[0001] The present invention relates to a cladding system for buildings.
[0002] Cladding is an outer skin applied to a building with the purpose of providing weather
protection, insulation, and/or desired aesthetics. There are many different known
cladding systems, involving a range and combination of materials and styles. Some
cladding systems use composite panels or glass to provide the cladding surface. However,
it is often desirable for the cladding to provide the appearance of traditional brickwork.
One reason for using cladding to provide the effect of traditional brickwork is that
the number of skilled bricklayers is decreasing so it is becoming more difficult,
and in some cases prohibitively expensive, to implement traditional bricklaying methods.
However, the resulting cladding panels are heavy and unwieldy. Some panels are sized
up to 6 metres tall and 3 metres wide and they are difficult to handle, expensive
to transport and difficult to manage onsite, requiring a large workforce to oversee
installation. In addition, due to the weight of the cladding panels, it is required
to use many mounting points to ensure that the cladding panels are secured to the
building, which again increases the installation time and materials required on site.
One solution is to simply make the panels in smaller sizes, and it is known to provide
0.5 m
2 panels, however, the onsite assembly time is drastically increased with these panels
as the workers are required to install significantly more panels to create the same
finish as when using larger panels.
[0003] Brick-slip cladding systems are also known, wherein the outer surface is provided
by thin sections of traditional brick (referred to as 'brick slips'). In some known
systems, the brick slips are glued to a panel, which is then in turn fixed to the
building to provide the cladding. The problem with using adhesives is that they will
fail over time, and further, in the event of a fire, when burned, the adhesives can
release toxins which can travel throughout the building and intoxicate inhabitants
distal to the source of the fire. It is therefore desirable to use an alternative
solution to adhesives.
[0004] In known brick-slip cladding systems, the supporting framework which supports the
cladding panels is assembled onsite and the panels are then in turn installed on the
framework. The gap between the panels where the brick slips from adjacent panels meet
is then pointed. Again, with these systems, the panels are small (approximately 0.5
m
2), meaning that there is still a significant amount of pointing required onsite, and
the onsite time is considerable due to the pointing requirements and the assembly
of the framework.
[0005] In some known cladding systems, the arrangements used for mounting the cladding panels
to the building structure often do not provide a sufficient cavity between the panel
and the building structure. A minimum cavity of 50 mm is recommended, and this cannot
be obtained by some known systems. There is also a problem with regards to adjustability
of cladding panels during installation. Typically, installation involves fixing a
bracket to the building and a further bracket to the panel which are configured to
engage with one another. The panel is then installed such that the brackets engage.
However, there are often fine margins of error because the panel must align with all
adjacent panels, and the cavity spacing (between the cladding panel and the building
structure) must be consistent across the panels. If the brackets are not fixed in
the correct position, this can result in the panel not being correctly positioned
when it is installed.
[0006] It is therefore an object of the invention to obviate or mitigate the problems outlined
above in relation to cladding systems and particularly brick slip cladding systems.
[0007] According to an aspect of the invention there is provided a cladding system for a
building, the cladding system comprising a cladding panel, the cladding panel comprising
a frame and a backing member mounted on the frame, and wherein the backing member
is suitable for receiving covering elements thereto, the cladding system further comprising
a mounting means for mounting the cladding panel to a building structure.
[0008] Ideally, the cladding panel is formed mostly or entirely from non-combustible materials.
[0009] Preferably, during installation, the mounting means provides adjustability of the
cladding panel relative to the building structure towards or away from the building
and/or upwards or downwards with respect to the building and/or laterally with respect
to the building.
[0010] Ideally, the mounting means comprises a building mounting component to be mounted
to the building structure during installation, and a cladding-panel mounting component
to be mounted to the cladding panel. Preferably, the building mounting component and
the cladding-panel mounting component are separate components that are directly or
indirectly fixable to one another.
[0011] Preferably, the mounting means comprises an intermediate mounting component that
is fixable to the building mounting component and to the cladding-panel mounting component,
wherein the intermediate mounting component is arranged extending between the building
mounting component and the cladding-panel mounting component. Advantageously, use
of an intermediate mounting component provides a greater degree of adjustability when
installing the cladding panel because the position of the intermediate mounting component
relative to the building mounting component and relative to the cladding-panel mounting
component can be adjusted. Further, the intermediate mounting component spaces the
cladding-panel mounting component from the building component and can therefore increase
the size of the cavity between the panel and the building structure. Alternatively,
the building mounting component could be directly fixed to the cladding-panel mounting
component, but this provides less adjustability.
[0012] Ideally, the building mounting component comprises a building engagement portion
configured to engage with the building structure when the building mounting component
is fixed to a building structure. Preferably, the building engagement portion is adapted
to engage with a flat surface of a building structure. Ideally, the building engagement
portion can engage with a floor slab. Ideally, the building engagement portion is
fixable to a building structure. Preferably, the building engagement portion comprises
one or more apertures for receiving fixing elements such as bolts to fix the building
engagement portion to a surface, such as the surface of a floor slab.
[0013] Ideally, the building mounting component comprises a projection that projects from
the building engagement portion and which is configured to fix the building mounting
component to the intermediate and/or cladding-panel mounting component(s). Ideally,
there is a cavity located between the panel and the building structure when the panel
is installed. The size of the projection and/or the intermediate mounting component,
and the connection between the two, defines the size of the cavity between the cladding
panel and the building structure. Ideally, the cavity is 50 mm or greater, but variations
in this will be apparent to the skilled person.
[0014] Preferably, the building engagement portion is planar. Ideally, the projection is
a flange, most preferably a planar flange, arranged extending from the building engagement
portion. Ideally, the projection is arranged at 90° or approximately 90° to the building
engagement portion. Ideally, the projection is located centrally, or approximately
centrally, along the length of the building engagement portion.
[0015] Ideally, the projection of the building mounting component comprises one or more
apertures to receive fixing elements to fix, most preferably to releasably fix, the
building mounting component to the intermediate mounting component and/or cladding-panel
mounting component(s). Ideally, the one or more apertures are elongate slots. Ideally,
there are two or more elongate slots which are most preferably arranged in parallel
with respect to one another. Advantageously, use of an elongate slot provides adjustability
along the length of the slot. Ideally, the longitudinal axis of the slot is arranged
perpendicular to the building engagement portion. Advantageously, when installed,
this means adjustability is provided towards and away from the building structure.
[0016] Preferably, the mounting means comprises a grip means to prevent relative movement
between the different components of the mounting means such as the building mounting
component, the cladding-panel mounting component and/or the intermediate mounting
component, when the mounting means or component parts thereof is assembled.
[0017] Preferably, the grip means prevents relative movement between the building mounting
component and the intermediate mounting component and/or relative movement between
the intermediate mounting component and the cladding-panel mounting component, when
the intermediate mounting component and cladding-panel mounting component are in engagement
with one another.
[0018] Ideally, the grip means comprises all or part of a surface of the building mounting
component, most preferably all or part of a surface of the projection of the building
mounting component, having a topography that can engage with all or part of a surface
of the intermediate mounting component having a corresponding topography, or with
all or part of a surface of the cladding-system mounting component having a corresponding
topography, in more than one configuration. Advantageously, if during installation
it is desired to adjust the relative position of the building mounting component and
the intermediate mounting component, for example, the component topographies can be
disengaged and re-engaged in a different configuration.
[0019] Ideally, the surface topography is provided by indentations, ridges, grooves, bumps,
teeth, crenelations or other suitable formation or any combination thereof.
[0020] Ideally, the indentations, ridges, grooves, bumps, teeth, crenelations or other suitable
formation or any combination thereof are provided around the aperture or apertures
of the projection of the building mounting component.
[0021] Ideally, the surface topography is provided by a series of ridges, most preferably
arranged in parallel with respect to one another.
[0022] The indentations, ridges, grooves, bumps, teeth, crenelations or other suitable formation
or any combination thereof may be integrally formed with the projection of the building
mounting component, or may be provided by a separate piece fixed to the projection
to provide the topography.
[0023] Ideally, the intermediate mounting component has a first part for engaging with the
building mounting component and a second part for engaging with the cladding-panel
mounting component.
[0024] Ideally, the first and/or second parts of the intermediate mounting component are
planar parts.
[0025] Preferably, the first part is arranged at 90° or approximately 90° to the second
part.
[0026] Ideally, the first and second parts are provided by an angle bracket.
[0027] Ideally, the first part comprises one or more apertures to receive fixing elements
to releasably fix the intermediate mounting component to the building mounting component.
Ideally, the one or more apertures are elongate slots. Ideally, there are two or more
elongate slots which are most preferably longitudinally aligned with respect to one
another such that they are arranged on the same longitudinal axis. Ideally, when installed,
the longitudinal axis of the elongate slot of the intermediate mounting component
is arranged at 90° or approximately 90° to the longitudinal axis of the elongate slot
of the projection of the building mounting component. Advantageously, the orientation
of the slot provides adjustability upwards or downwards with respect to the building
structure.
[0028] Ideally, the grip means comprises all or part of a surface of the intermediate mounting
component, most preferably all or part of a surface of the first part of the intermediate
mounting component having a topography that can engage with all or part of a surface
of the building mounting component having a corresponding topography, in more than
one configuration. Advantageously, if during installation it is desired to adjust
the relative position of the intermediate mounting component and the building mounting
component, for example, the component topographies can be disengaged and re-engaged
in a different configuration.
[0029] Ideally, the surface topography is provided by indentations, ridges, grooves, bumps,
teeth, crenelations or other suitable formation or any combination thereof.
[0030] Ideally, the indentations, ridges, grooves, bumps, teeth, crenelations or other suitable
formation or any combination thereof are provided around the aperture or apertures
of the first part of the intermediate mounting component.
[0031] The indentations, ridges, grooves, bumps, teeth, crenelations or other suitable formation
or combination thereof may be integrally formed with the first part of the intermediate
mounting component, or may be provided by a separate piece fixed to the first part
to provide the topography.
[0032] Ideally, the intermediate mounting component, most preferably the second part of
the intermediate mounting component, comprises one or more apertures to receive fixing
elements to releasably fix the intermediate mounting component to the cladding-panel
mounting component.
[0033] Preferably, the cladding-panel mounting component comprises a first part for engaging
with the intermediate mounting component and a second part for engaging with the cladding
panel.
[0034] Ideally, the first and/or second parts of the cladding-panel mounting component are
planar parts. Preferably, the first part is arranged at 90° or approximately 90° to
the second part. Ideally, the first and second parts are provided by an angle bracket.
[0035] Ideally, the cladding-panel mounting component, most preferably the first part of
the cladding-panel mounting component, comprises one or more apertures to receive
fixing elements to releasably fix the cladding-panel mounting component to the intermediate
mounting component. Ideally, the one or more apertures are elongate slots.
[0036] The cladding-panel mounting component may be operable to provide a shelf on which
a cladding panel can be mounted, and/or the cladding-panel mounting component may
be operable to suspend a panel from the cladding-panel mounting component and therefore
from the mounting means and the building structure. Ideally, the cladding system comprises
a first cladding-panel mounting component operable as a shelf for cladding panels,
and a second cladding-panel mounting component operable to suspend a panel from the
mounting means.
[0037] Ideally, at least in the cladding-panel mounting component that is operable as a
shelf for cladding panels, there are two or more elongate slots which are most preferably
longitudinally aligned with respect to one another such that they are arranged on
the same longitudinal axis. Ideally, when installed, the first part of the cladding-panel
mounting component is parallel or substantially parallel with the building engagement
portion of the building mounting component. Ideally, the longitudinal axis of the
elongate slot in the first part of the cladding-panel mounting component is aligned
with the longitudinal axis of the first part. Advantageously, this provides lateral
adjustability of the cladding panel during installation. Alternatively, the elongate
slot could be provided on the second part of the intermediate mounting component to
provide lateral adjustability.
[0038] Ideally, the perimeter of the elongate slot or slots of the cladding-panel mounting
component comprises a series of teeth adapted to engage with a corresponding series
of teeth on the outer boundary of a washer. Advantageously, a washer may be inserted
into the elongate slot such that the teeth of the washer and the teeth of the perimeter
of the elongate slot engage one another, and this prevents movement of the washer
along the length of the slot. A bolt or other suitable fixing element can then be
inserted through the washer and through the aperture on the second part of the intermediate
mounting component to fix the intermediate mounting component to the cladding-panel
mounting component. To adjust the lateral position of the cladding panel with respect
to the building structure, the washer can be removed from the elongate slot, repositioned,
and reinserted as desired.
[0039] Preferably, the cladding-panel mounting component can be used to mount an upper part
of a first panel and a lower part of a second panel directly above the first panel.
Advantageously, a single cladding-panel mounting component can be used for two panels,
and the height of two floors may be cladded by using just two panels, and three sets
of mounting means.
[0040] Ideally, the cladding-panel mounting component, most preferably the second part of
the cladding-panel mounting component, comprises fixing means for fixing the cladding-panel
mounting component to the cladding panel. Ideally, the fixing means are fixing elements
that extend from the second part and that can engage with an opening or aperture on
the cladding panel to enable fixing thereto. Ideally, the fixing elements are spaced
apart and extend from either or, most preferably, both planar sides of the second
part of the cladding-panel mounting component. Advantageously, the second part provides
a shelf to which the cladding panel can be fixed. The fixing elements extending below
the second part of the cladding-panel mounting component can engage with a panel below
the cladding-panel mounting component, whereas the fixing elements extending above
the second part of the cladding-panel mounting component can engage with a panel that
is above and preferably sitting on the second part of the cladding-panel mounting
component. The same cladding-panel mounting component can be used on the lower surface
of the cladding panel, wherein the second part of the cladding-panel mounting component
extends below the cladding panel, as well as on the upper surface of the cladding
panel wherein the second part extends above the cladding panel.
[0041] The cladding-panel mounting component may be mounted via two intermediate mounting
components to two building mounting components. Two cladding-panel mounting components
may be used per each cladding panel.
[0042] The fixing elements used to fix the building mounting component to the intermediate
mounting component, and to fix the intermediate mounting component to the cladding-panel
mounting component may be a nut-and-bolt or other suitable fixing elements.
[0043] Ideally, a lower cladding-panel mounting component can be mounted on a floor slab
of a building, and an upper cladding-panel mounting component can be mounted on the
floor slab immediately above the floor slab to which the lower cladding-panel mounting
component is mounted, with the cladding panel mounted extending therebetween. Advantageously,
one cladding panel can be used extending the entire height between the two floor slabs.
[0044] Ideally, the backing member is formed from a non-combustible material. Preferably,
the backing member is formed from cementitious material such as calcium silicate fibre
cement or magnesium oxide board. Ideally, in one embodiment the panel does not use
a cement particle board. Advantageously, the backing member can readily receive mechanical
fixings, such as screws or bolts, to mechanically fix a covering element thereto.
Further advantageously, the backing member is relatively light in weight compared
to other backing members, such as steel or concrete. The combination of a frame and
lightweight backing member, rather than a concrete panel, means the cladding panel
overall is much lighter and therefore easier to transport and install than known cladding
panels. Ideally, the backing member is fitted to the frame before transportation.
Advantageously, it is not required to assemble the frame onsite, and onsite installation
times are reduced.
[0045] Preferably, one or more covering elements are fixed to the backing member.
[0046] Ideally, the one or more covering elements are mechanically fixed to the backing
member.
[0047] Ideally, the one or more covering elements are fixed to the backing member via one
or more horizontal rails.
[0048] Ideally, the one or more covering elements are fixed to the frame via one or more
horizontal rails.
[0049] Ideally, the one or more covering elements are fixed to the frame via one or more
horizontal rails and clips which are configured to support the covering elements on
the rails.
[0050] Ideally, the one or more covering elements are masonry slips such as brick slips,
block slips or stone slips, or composite slips such as glass-reinforced plastic (GRP)
slips, or a combination thereof.
[0051] Ideally, the covering elements have a front face, a rear face, and side faces extending
between the front face and the rear face. In use, the rear face engages with the backing
member.
[0052] Ideally, there is a slot in one or more side faces, ideally in at least two side
faces, of the covering elements, the slot being configured to receive a fixing element.
Ideally, the slot is located at a position in the side face between the rear face
and the front face.
[0053] Ideally, the covering elements are fixed to the backing member by a covering-element
fixing element that is disposed in the slot of the covering element, and which is
in turn fixed to the backing member.
[0054] Ideally, the covering-element fixing element is a bracket which has a flange that
engages the slot in the covering element, a first portion that extends from the flange
towards the backing member and then a second portion that extends from the first portion
and is fixed or fixable to the backing member. Ideally, the second portion comprises
an aperture for receiving a screw. The aperture may be elongate, thereby providing
adjustability of the bracket relative to the screw during installation.
[0055] The bracket may comprise a third portion that extends from the second portion to
a second flange engaged in the slot of an adjacent covering element. The bracket is
therefore substantially U-shaped.
[0056] Alternatively, the flange may be sized to extend from a slot in one covering element
to a slot in an adjacent covering element. Advantageously with this fixing element
there is no requirement for the third portion and second flange. The flange may be
planar and it may be substantially U-shaped. The flange may have a polygonal perimeter,
ideally having three sides, or it may be rounded.
[0057] A further fixing element is provided which is ideally used to mechanically attach
covering elements located at the side of the backing member. In this fixing element,
the flange and the second portion are mutually opposed. The first portion is sized
such that the flange engages a slot in one covering element and the second portion
is disposed to the rear of the backing member, where it can then be fixed with a screw.
The length of the first portion is therefore equal to or greater than the width of
the backing member and the width of the covering element from the rear of the covering
element to the slot.
[0058] Adhesives may also be used with the mechanical fix to enhance the connection between
the covering elements and the backing member.
[0059] Preferably, the frame comprises a plurality of structural frame elements that are
connected to one another and/or integrally formed with one another to define a frame.
[0060] Ideally, the cladding panel is arranged with the frame defining the rear of the cladding
panel, with the backing member having a front surface for receiving covering elements.
Ideally, no part of the frame is visible on the front surface. Preferably, no part
of the frame extends to the front surface.
[0061] Ideally, the panels are designed such that the covering elements dovetail along the
panel joint.
[0062] Ideally, the covering elements dovetail the panel at corner joints.
[0063] Ideally, the covering elements dovetail the panel at planar joints.
[0064] Preferably, the covering elements and the panel interlock to each other via corresponding
recesses and projecting covering elements provided in adjacent panels in such a manner
that no part of the panel is visible on the front surface of the building.
[0065] Ideally, the frame is mountable to the cladding-panel mounting component. The cladding-panel
mounting component may be pre-mounted on the cladding panel before transport to the
building site.
[0066] Ideally, the frame comprises one or more structural frame elements extending longitudinally
in a first direction, and one or more structural frame elements extending longitudinally
in a second direction. Ideally, the second direction is perpendicular or substantially
perpendicular to the first direction.
[0067] Ideally, the frame comprises an upper frame element, arranged at or close to the
upper edge of the backing member.
[0068] Ideally, the frame comprises a lower frame element, arranged at or close to the lower
edge of the backing member.
[0069] Ideally, the upper and/or lower frame elements have apertures or openings that are
configured to receive the fixing elements of the cladding-panel mounting component.
[0070] The cladding panel may be mounted on the cladding-panel mounting component without
having to secure the cladding panel thereto. Advantageously, this reduces complexity
of the installation. The cladding panel can be installed by simply setting it onto
a cladding-panel mounting component which is mounted on the building structure, such
that the fixing elements of the cladding-panel mounting component extend through the
apertures on the lower frame element. A cladding-panel mounting component can then
be set on the upper frame element such that the fixing elements of the cladding-panel
mounting component extend through apertures on the upper frame element. The upper
cladding-panel mounting component can then be secured to the building.
[0071] Preferably, the frame comprises a side frame element, arranged at or close to the
side of the backing member. Preferably, the frame comprises two side frame elements,
one arranged at each side of the backing member.
[0072] Ideally, the side frame element extends between the upper and lower frame elements.
[0073] Ideally, the frame comprises one or more intermediate frame elements located extending
partially or entirely between the upper and lower frame elements, and/or located extending
partially or entirely between the two side frame elements. Advantageously, this strengthens
the frame and the cladding panel.
[0074] Ideally, the frame is formed from a metal. Preferably, a majority of the frame is
formed from steel and most preferably from light gauge steel. Ideally, at least 50%,
60%, 70%, 80%, 90%, 95%, 96%, 97%, 98% or 99% of the frame is formed from steel, most
preferably light gauge steel. The entirety of the frame may be formed from steel,
most preferably light gauge steel (with the possible exception of fixing elements
or materials used to fix the structural frame elements together to form the frame,
which may be formed from different materials to the frame elements). Light gauge steel
is also known as cold-formed steel or cold-rolled steel. Use of light gauge steel
ensures that the cladding panel is light in weight, and it can therefore be made to
a larger size than known brick-slip cladding panels without becoming unwieldy and
difficult to transport. Advantageously, a panel spanning an entire floor may be made
in this way.
[0075] The backing member may be provided by a single sheet of material, or it may be multiple
sheets fixed to the frame and/or joined together.
[0076] Ideally, the panels are arrangeable extending between two floor slabs on a building,
such that the panel extends from floor-to-floor.
[0077] Ideally, one panel is shaped to provide a flat outer surface of covering elements.
[0078] Ideally, a further panel is shaped to provide the appearance of a stepped column.
In this panel, the frame is arranged to provide the frame of a stepped column, with
the backing member fixed thereto.
[0079] Ideally, yet a further panel is arranged having both a fascia surface and a soffit
surface. Advantageously, said panel can be used extending across openings such as
windows, with the soffit surface extending in towards the building opening.
[0080] Combinations of the features of the stepped column and/or soffit surface may be integrated
into a single panel and panels may be made with openings to accommodate windows, for
example.
[0081] Ideally, the panel with the soffit surface has part of the backing member fixed to
one part of the frame defining a fascia surface, and a further part of the backing
member fixed to a further part of the frame defining a soffit surface, wherein the
soffit surface is perpendicular or substantially perpendicular to the fascia surface.
[0082] Ideally, the frame of the panel with the soffit surface comprises a soffit frame
element that extends along the rear of the backing member that defines the soffit
surface. Ideally, the soffit frame element is a C-shaped beam. Ideally, one side of
the C-shape beam extends along the rear of the soffit surface.
[0083] Ideally, the panel with the soffit surface is mountable to the intermediate mounting
component. Ideally, the panel with the soffit surface is mounted by a cladding-panel
mounting component for suspending the panel from the mounting means. Ideally, the
cladding-panel mounting component for suspending the panel is mounted in turn on the
frame of the panel with the soffit surface. Ideally, the frame of the panel with the
soffit surface is configured to receive the cladding-panel mounting component. Ideally,
the frame comprises a surface, most preferably a planar surface, for receiving the
cladding-panel mounting component. Ideally, the surface for receiving the cladding-panel
mounting component comprises one or more apertures to receive the cladding-panel mounting
component. Ideally, the surface for receiving the cladding-panel mounting component
is located proximal to the side of the panel and preferably proximal to the upper
part of the panel.
[0084] Ideally, the cladding-panel mounting component for suspending a panel comprises an
engagement means to engage with the aperture of the surface on the panel. Ideally
the engagement means is a hook or hooks. Most preferably, the cladding-panel mounting
component comprises two spaced apart hooks that engage with two spaced apart apertures
on the panel. Preferably, a portion of the cladding-panel mounting component for suspending
a panel, most preferably a planar portion, extends from at or about the engagement
means, most preferably perpendicularly to the engagement means. Ideally, the cladding-panel
mounting component for suspending a panel comprises a tab that is arranged perpendicularly
to the engagement means and/or perpendicularly to the portion that extends from at
or about the engagement means. The tab abuts an upper surface of the upper frame element
of the panel with the soffit surface when the cladding-panel mounting component is
fitted to the panel. The tab can be fixed to the frame of the panel with the soffit
surface to secure the cladding-panel mounting component to the panel. Ideally, the
tab has an aperture for receiving a fixing element.
[0085] Preferably, the portion of the cladding-panel mounting component for suspending a
panel that extends from at or about the engagement means comprises an aperture, most
preferably an elongate slot, to receive fixing elements to fix the mounting component
to the intermediate mounting component or building mounting component. Ideally, the
perimeter of the elongate slot comprises a series of teeth adapted to engage with
a corresponding series of teeth on the outer boundary of a washer. Ideally, the longitudinal
axis of the slot extends from the upper to lower part of the portion that extends
from at or about the engagement means, thereby providing adjustability upwards or
downwards of the panel with the soffit surface.
[0086] It should be noted that the flat panel or stepped-column panel could be configured
to be mounted via the cladding-panel mounting component for suspending a panel, and
the panel with a soffit surface could be configured to be mounted via the cladding-panel
mounting component that is operable as a shelf.
[0087] The cladding panel may extend for at least 1 m, at least 2 m, at least 3 m, at least
4 m, at least 5 m or at least 6 m in one direction. The cladding panel may have a
surface area of at least 1 m
2, at least 4 m
2, at least 9 m
2, at least 16 m
2, or at least 25 m
2. Advantageously, despite large sizes, the cladding panel is not unwieldy due to being
formed from lightweight materials.
[0088] According to a further aspect of the invention there is provided a cladding panel
for a building, the cladding panel comprising a frame, and a backing member mounted
on the frame, the backing member being suitable for receiving brick slips or other
covering elements thereto.
[0089] The cladding panel may comprise any features in any combination of any cladding panel
described above in relation to the cladding system.
[0090] According to a further aspect of the invention there is provided a mounting means
for mounting cladding panels to a building structure.
[0091] The mounting means may comprise any features in any combination of the mounting means
described above in relation to the cladding system.
[0092] According to a further aspect of the invention there is provided a building, wherein
the building is cladded with a cladding system.
[0093] The cladding system may comprise any features in any combination of the cladding
system described above.
[0094] Ideally, the building comprises a flat surface provided by a cladding panel mounted
extending between two spaced apart floor slabs. Ideally, wherein one floor slab is
located above the other floor slab.
[0095] Ideally, the building comprises a stepped column provided by a cladding panel mounted
extending between two spaced apart floor slabs. Ideally, wherein one floor slab is
located above the other floor slab.
[0096] Ideally, the building comprises a soffit surface and fascia surface provided by a
cladding panel.
[0097] Ideally, the majority of the building is cladded in the cladding system. Most preferably,
at least 80%, 85%, 90% or 95% of the building is cladded in the cladding system.
[0098] According to a further aspect of the invention there is provided a method for cladding
a building with a cladding system as described above.
[0099] Ideally, the method comprises fixing the building mounting component to a building
structure, such as a floor slab.
[0100] Preferably, the method comprises fixing an intermediate mounting component to the
building mounting component. The method may comprise a readjustment step wherein the
alignment between the intermediate mounting component and the building mounting component
is checked after engagement between the surface topographies of the components, and
wherein the components are disengaged, adjusted and re-engaged.
[0101] Ideally, the method comprises fixing a cladding-panel mounting component on the intermediate
mounting component. The method may comprise a readjustment step wherein the alignment
between the cladding-panel mounting component and the intermediate mounting component
is checked after the washer is inserted into the elongate slot of the cladding-panel
mounting component, and wherein the washer is removed, the alignment between the cladding-panel
mounting component and intermediate mounting component is adjusted, and wherein the
washer is reinserted.
[0102] Ideally, the method comprises using fixing elements such as a nut-and-bolt to fix
the building mounting component to the intermediate component and/or to fix the intermediate
component to the cladding-panel mounting component.
[0103] The method may then comprise the step of fixing a panel on a cladding-panel mounting
component. The panel may be fixed by fixing elements such as nuts and bolts or another
suitable fixing element.
[0104] The method may comprise mounting the cladding panel on the cladding-panel mounting
component without securing the cladding panel thereto with a nut or other fixing element.
The method may comprise installing the cladding panel by simply setting it onto a
cladding-panel mounting component which is mounted on the building structure, such
that cladding-panel mounting component supports the cladding panel. Ideally, the method
comprises installing the cladding panel such that the fixing elements of the cladding-panel
mounting component extend through the apertures on the lower frame element. The method
may then comprise setting a cladding-panel mounting component on the upper frame element
such that the fixing elements of the cladding-panel mounting component extend through
apertures on the upper frame element. The method may comprise then securing the upper
cladding-panel mounting component to the building. The method may comprise setting
a second panel on the upper cladding-panel mounting component directly above the panel.
The method may involve stacking subsequent panels in this manner to clad the building.
[0105] The panel may be a flat panel, stepped-column panel or panel with a soffit surface.
The method may comprise pre-fitting the cladding-panel mounting component or mounting
component for a panel with a soffit surface to the panel, then raising the panel and
fixing the cladding-panel mounting component or mounting component for a panel with
a soffit surface to the intermediate mounting component or building mounting component.
Alternatively, the method may comprise first fixing the cladding-panel mounting component
to the intermediate component or building mounting component, then raising the panel
and fixing the panel to the cladding-panel mounting component. Ideally, the panels
are prefabricated before transport to a site for installation. Ideally, the backing
member is secured to the frame with screws or other suitable fixing means before transport
to a site for installation. Ideally, the covering elements are fitted to the backing
member, and spacing between the covering elements filled with mortar before transport
to a site for installation.
[0106] Ideally, the method comprises the step of installing a single panel extending from
one floor to the floor directly above or below said floor. The method may comprise
installing a plurality of panels adjacent to each other to clad the majority or entirety
of a building. Ideally, the method comprises the step of installing a panel suspended
from the mounting means.
[0107] The method may comprise the step of fitting waterproof membranes and/or insulation
between and/or around the panels.

[0109] In the drawings there is shown a cladding system for a building, the cladding system
being indicated generally by reference numeral 2. The cladding system 2 comprises
a cladding panel which is mountable to a building structure. In the illustrated embodiment,
the cladding system 2 comprises three cladding panels of different shapes. Figures
1 to 8 illustrate a flat panel indicated by reference numeral 4, Figures 9 to 18 illustrate
a stepped column panel indicated by reference numeral 6, and Figures 19 to 26 illustrate
a panel with a soffit surface, the panel being indicated by reference numeral 8. The
cladding panels 4, 6, 8 have a frame 10 and a backing member 12 mounted on the frame
10. The backing member 12 is suitable for receiving covering elements 14. In the illustrated
embodiment, there are brick slips 14 fixed to the backing member 10.
[0110] The cladding system 2 further comprises a mounting means 16 for mounting the cladding
panels 4, 6, 8 to a building structure. In the illustrated embodiment, the flat panel
4 and stepped column panel 6 are each shown mounted to a floor slab 18. The cladding
panels 4, 6, 8 are formed from non-combustible materials and are therefore suitable
for use in high-rise buildings (i.e., over 18 metres tall) in the UK, where regulations
currently prohibit use of flammable materials on the exterior of buildings. The mounting
means 16 provides adjustability of the cladding panels 4, 6, 8 relative the building
structure towards and away from the building and upwards and downwards with respect
to the building. The mounting means 16 can also provide adjustability of the flat
and stepped-column panels 4, 6 laterally with respect to the building structure.
[0111] The mounting means 16 comprises a building mounting component 20 to be mounted to
the building during installation. The mounting means 16 further comprises a cladding-panel
mounting component 22 to be mounted to the cladding panel 4, 6. The cladding-panel
mounting component 22 is operable as a shelf on which the cladding panels 4, 6 can
be mounted. The mounting means 16 involves a cladding-panel mounting component 88
which is operable to suspend a panel from the mounting means 16 and is used with the
panel 8 as will be described in further detail below. The building mounting component
20 and the cladding-panel mounting components 22, 88 are separate components that
are directly or indirectly fixable to one another. The mounting means 16 further comprises
an intermediate mounting component 24 that is fixable to the building mounting component
20 and to the cladding-panel mounting components 22, 88. The intermediate mounting
component 24 is arranged extending between the building mounting component 20 and
the cladding-panel mounting component 22, 88. Use of the intermediate mounting component
24 provides a greater degree of adjustability when installing the cladding panel 4,
6 because the position of the intermediate mounting component 24 relative to the building
mounting component 20 and relative to the cladding-panel mounting component 22, 88
can be adjusted. Alternatively, the building mounting component 20 could be directly
fixed to the cladding-panel mounting component 22, 88, but this provides less adjustability.
[0112] The building mounting component 20 is illustrated in isolation in Figures 27 to 29.
The building mounting component 20 is formed from steel although other metals or materials
may be suitable, provided they are sufficiently strong to withstand the weight of
the cladding panels 4, 6, 8. The building mounting component 20 comprises a building-engagement
portion 26 configured to engage with the building structure when the building mounting
component 20 is fixed to a building structure. The building engagement portion 26
is adapted to engage with a flat surface of a building structure. Ideally, the building
engagement portion 26 can engage with a floor slab, as shown in Figure 1. In the illustrated
embodiment, the building engagement portion 26 is a flat, rectangular plate, although
the skilled person will understand that other shapes may be suitable for the same
purpose. The building engagement portion 26 comprises two apertures 28a, 28b in the
illustrated embodiment for receiving fixing elements such as bolts to fix the building
engagement portion 26 to a surface, such as the surface of a floor slab. The building
engagement portion 26 may have more or less than two apertures if desired.
[0113] The building mounting component 20 further comprises a projection 30 that projects
from the building engagement portion 26 and which is configured to fix the building
mounting component 20 to the intermediate and/or cladding-panel mounting component(s)
22, 24, 88. The size of the projection 30 and/or the intermediate mounting component
24 defines the size of the cavity between the cladding panel 4, 6, 8 and the building
structure.
[0114] The projection 30 is a rectangular, planar flange, arranged extending from the building
engagement portion 26. The skilled person will understand that other shapes may be
suitable for the same purpose. The projection is arranged at 90° to the building engagement
portion 26. The projection 30 is located centrally along the length of the building
engagement portion 26.
[0115] The projection 30 of the building mounting component 20 comprises two apertures 32a,
32b to receive fixing elements to releasably fix the building mounting component 20
to the intermediate and/or cladding-panel mounting component(s) 22, 24, 88. The projection
30 may have more or less than two apertures for this purpose if desired. The apertures
32a, 32b are elongate slots. The elongate slots 32a, 32b are arranged in parallel
with respect to one another. Use of an elongate slot provides adjustability along
the length of the slot. The longitudinal axis of each slot 32a, 32b is arranged perpendicular
to the building engagement portion 26. Advantageously, when installed, this means
adjustability is provided towards and away from the building structure.
[0116] The mounting means 16 further comprises a grip means 34 to prevent relative movement
between the building mounting component 20, the cladding-panel mounting component
22, 88 and/or the intermediate mounting component 24, when the cladding system 2 is
assembled. The grip means 34 comprises a surface of the projection 30 of the building
mounting component 20 having a topography that can engage with the all or part of
a surface of the intermediate mounting component 24 having a corresponding topography,
or with the all or part of a surface of the cladding-system mounting component 22,
88 having a corresponding topography, in more than one configuration. Therefore, if
during installation it is desired to adjust the relative position of the building
mounting component 20 and the intermediate mounting component 24, for example, the
component topographies can be disengaged and re-engaged in a different configuration.
The surface topography is provided by a series of ridges 36 arranged in parallel.
Any suitable formation, such as indentations, grooves, bumps, teeth, crenelations
or other suitable formation or combination thereof could be used provided it functions
to engage with a corresponding topography on another component. The ridges 36 are
provided located around the apertures 32a, 32b. The ridges 36 may be integrally formed
with the projection 30 of the building mounting component 20, or may be provided by
a separate piece fixed to the projection 30 to provide the topography. The longitudinal
axis of the ridges 36 is parallel with the longitudinal axis of the elongate slot
32a, 32b around which it is located. The ridges 36 are arranged defining a rectangular
outline.
[0117] The intermediate mounting component 24 has a first part 38 for engaging with the
building mounting component 20 and a second part 40 for engaging with the cladding-panel
mounting component 22, 88. The first and second parts 38, 40 of the intermediate mounting
component 24 are planar parts. In the illustrated embodiment, both the first and second
parts 38, 40 are rectangular, but variations in shape will be apparent to the skilled
person. The intermediate mounting component 24 is formed from steel although other
metals or materials may be suitable, provided they are sufficiently strong to withstand
the weight of the cladding panels 4, 6, 8. The first part 38 is arranged at 90° to
the second part 40. The first and second parts 38, 40 are provided by an angle bracket.
[0118] The first part 38 comprises two apertures 42a, 42b to receive fixing elements to
releasably fix the intermediate mounting component 24 to the building mounting component
20. It should be noted that, in the drawings, the fixing elements are not illustrated
in every drawing for the purposes of clarity, as illustrating the fixing elements
would obscure the other important features of the drawings. In Figure 1, fixing elements
106 are illustrated between the building mounting component 20 and the intermediate
mounting component 22, and between the building mounting component 20 and the floor
slab 18. More or less than two apertures may be present as desired. The apertures
42a, 42b are elongate slots. The elongate slots longitudinally aligned with respect
to one another such that they are arranged on the same longitudinal axis. When installed,
the longitudinal axis of the elongate slots of the intermediate mounting component
24 is arranged at 90° to the longitudinal axis of the elongate slot of the projection
30 of the building mounting component 20. The orientation of the slot therefore provides
adjustability upwards or downwards with respect to the building structure.
[0119] The grip means 34 comprises all or part of a surface of the first part 38 of the
intermediate mounting component 24 having a topography that can engage with all or
part of a surface of the building mounting component 20 having a corresponding topography,
in more than one configuration. If, during installation, it is desired to adjust the
relative position of the intermediate mounting component 24 and the building mounting
component 20, for example, the component topographies can be disengaged and re-engaged
in a different configuration. The surface topography is provided by a series of ridges
44 arranged in parallel. Any suitable formation, such as indentations, grooves, bumps,
teeth, crenelations or other suitable formation or combination thereof could be used
provided it functions to engage with a corresponding topography on another component.
The ridges 44 are provided located around the apertures 42a, 42b. The ridges 44 may
be integrally formed with the first part 38 of the intermediate mounting component
24, or may be provided by a separate piece fixed to the first part 38 to provide the
topography. The longitudinal axis of the ridges 44 is perpendicular with the longitudinal
axis of the elongate slot 42a, 42b around which it is located. The ridges 44 are arranged
defining a rectangular outline. When assembled, the ridges 44 of the first part 38
of the intermediate mounting component 24, and the ridges 36 of the projection 30
of the building mounting component 20 extend longitudinally in the same direction,
with the ridges 44 of the first part 38 of the intermediate mounting component 24
fitting between the ridges 36 of the projection 30 of the building mounting component
20.
[0120] The second part 40 of the intermediate mounting component 24 comprises an aperture
46 to receive fixing elements to releasably fix the intermediate mounting component
24 to the cladding-panel mounting component 22. The second part 40 may have more than
one aperture for additional fixing elements if desired.
[0121] The cladding-panel mounting component 22, which is operable as a shelf for the flat
panel 4 and stepped-column panel 6, has a first part 48 for engaging with the intermediate
mounting component 24 and a second part 50 for engaging with the cladding panel 4,
6. The first and second parts 48, 50 of the cladding-panel mounting component 22 are
planar, rectangular parts. The cladding-panel mounting component 22 is formed from
a steel angle bracket, although alternative materials or shapes may be used if desired.
The first part 48 is arranged at 90° to the second part 50. The first part 48 has
two apertures 52a, 52b to receive fixing elements to releasably fix the cladding-panel
mounting component 22 to the intermediate mounting component 24. More or less than
two apertures could potentially be used if desired. The apertures 52a, 52b are elongate
slots. The elongate slots are longitudinally aligned with respect to one another such
that they are arranged on the same longitudinal axis. When installed, the first part
48 of the cladding-panel mounting component 22 is parallel or substantially parallel
with the building-engagement portion 26 of the building mounting component 20. The
longitudinal axis of the elongate slots 52a, 52b is aligned with the longitudinal
axis of the first part 48 of the cladding-panel mounting component 22. This provides
lateral adjustability of the cladding panel 4, 6 during installation.
[0122] The perimeter of the elongate slots 52a, 52b of the cladding-panel mounting component
22 comprises a series of teeth 54 adapted to engage with a corresponding series of
teeth (not shown) on the outer boundary of a washer (not shown). Advantageously, a
washer may be inserted into the elongate slot 52a, 52b such that the teeth of the
washer and the teeth of the perimeter of the elongate slot 52a, 52b engage one another
and this prevents movement of the washer along the length of the slot 52a, 52b. A
bolt or other suitable fixing element can then be inserted through the washer and
through the aperture 46 on the second part 40 of the intermediate mounting component
24 to fix the intermediate mounting component 24 to the cladding-panel mounting component
22. To adjust the lateral position of the cladding panel 4, 6 with respect to the
building structure, the washer can be removed from the elongate slot 54a, 54b, repositioned,
and reinserted as desired.
[0123] The second part 50 of the cladding-panel mounting component 22 has fixing means 56
for fixing the cladding-panel mounting component 22 to the cladding panel 4, 6. The
fixing means 56 are fixing elements 58a, 58b that extend from the second part 50 and
that can engage with an opening or aperture on the cladding panel 4, 6 to enable fixing
thereto. The fixing elements 58a, 58b are spaced apart and extend from both planar
sides of the second part 50 of the cladding-panel mounting component 22. The second
part 50 provides a shelf to which the cladding panel 4, 6 can be fixed. The same cladding-panel
mounting component 22 can be used on the lower surface of the cladding panel 4, 6,
wherein the second part 50 of the cladding-panel mounting component 22 extends below
the cladding panel 4, 6, as well as on the upper surface of the cladding panel 4,
6 wherein the second part 50 extends above the cladding panel 4, 6. Ideally, each
cladding-panel mounting component 22 is mounted via two intermediate mounting components
24 to two building mounting components 20. Two cladding-panel mounting components
22 may be used per each cladding panel 4, 6. Two panels may be mounted on one cladding-panel
mounting component 22, wherein one panel is located above the second part 50, and
one panel is located below the second part 50.
[0124] The fixing elements are used to fix the building mounting component 20 to the intermediate
mounting component 24 and to fix the intermediate mounting component 24 to the cladding-panel
mounting component 22 may be a nut-and-bolt or other suitable fixing elements.
[0125] A lower cladding-panel mounting component 22 can be mounted on a floor slab 18 of
a building, and an upper cladding-panel mounting component 22 can be mounted on the
another floor slab 18 immediately above the floor slab 18 to which the lower cladding-panel
mounting component 22 is mounted, with the cladding panel 4, 6 mounted extending therebetween.
Advantageously, one cladding panel 4, 6 can be used extending the entire height between
the two floor slabs 18. This arrangement is illustrated in Figures 3, 4, 11 and 12.
[0126] The backing member 12 is formed from calcium silicate fibre cement but other non-combustible
material, preferably cementitious materials may be used if desired. The backing member
12 can readily receive mechanical fixings, such as screws or bolts, to mechanically
fix a covering element thereto. In the illustrated embodiment a plurality of covering
elements 14, which are brick slips, are mechanically fixed to the backing member 12.
Other masonry slips such as block, or stone slips, or composite slips such as GRP
slips, or combinations thereof could be used. Slips or sheets of any other desirable
material could be fixed to the backing member 14 if desired.
[0127] The covering elements 14 have a front face 60, a rear face 62, and side faces 64
extending between the front face 60 and the rear face 62. The rear face 62 abuts the
backing member 12. There is a slot 66 that extends along the side faces 64, the slot
66 being configured to receive a fixing element. The slot 66 is located at a position
in the side face 64 between the rear face 62 and the front face 60. The covering elements
14 are fixed to the backing member 12 by a fixing element 68 that is disposed in the
slot 66 of the covering element, and which is in turn fixed to the backing member
12.
[0128] The fixing element 68 is a bracket which has a flange 70a that engages the slot 66
in the covering element 14, a first portion 72a that extends from the flange 70a towards
the backing member 12 when in use and then a second portion 72b that extends from
the first portion 72a and abuts and is fixed to the backing member 12. The second
portion 72b comprises an aperture 74 for receiving a screw. The fixing element 68
comprises a third portion 72c that extends from the second portion 72b to a second
flange 70b engaged in the slot 66 of an adjacent covering element 14. The bracket
is therefore substantially U-shaped.
[0129] In Figure 39 there is a further fixing element for covering elements indicated by
reference numeral 108. The fixing element 108 has first and second portions 114, 116.
There is an elongate aperture 110 in the second portion for receiving a screw. The
elongate aperture 110 provides adjustability of the bracket relative to the screw
during installation. The fixing element 108 has a flange 112, similar to the flange
70a of the fixing element 68, for engaging a slot 66 in the side of a covering element
14. The flange 112 extends from the first portion 114, and the second portion 116
extends from an opposing end of the first portion 114. The flange 112 is sized to
extend from a slot in one covering element to a slot in an adjacent covering element
14. Advantageously with this fixing element there is no requirement for the third
portion 72b and second flange 70b. The flange 112 is planar and is substantially U-shaped.
The flange 112 has three outer sides, but may have more sides if desired. The flange
108, first portion 114 and second portion 116 are formed by initially providing a
planar piece, the perimeter of which forms the flange 108, then cutting and bending
the piece to provide the first and second portions 114, 116.
[0130] Figure 40 shows a further fixing element 118. The fixing element 118 is similar to
the fixing element 108, with the exception that it has a rounded flange 120.
[0131] Figure 41 shows a further fixing element 122 which is used to mechanically attach
covering elements 14 located at the side of the backing member 12. The fixing element
has a flange 124 for engaging a slot in a covering element, a first portion 126 extending
from the flange, and a second portion 128 extending from the first portion that is
fixable to the backing member 12. The flange 124 mutually opposes the second portion
128. The flange 124 has a rounded edge. The first portion 126 is sized such that the
flange 124 engages a slot in one covering element and the second portion 128 is disposed
to the rear of the backing member 12, where it can then be fixed with a screw thereby
securing the covering element on the backing member 12. The length of the first portion
126 is therefore equal to or greater than the width of the backing member 12 and the
width of the covering element 14 from the rear of the covering element to the slot
66.
[0132] Alternative shapes of fixing elements are within the scope of the invention provided
they engage with the slot 66 and can be fixed to the backing member 12 to secure the
covering element 14 mechanically to the backing member 12. Adhesives may also be used
with the mechanical fix to enhance the connection between the covering elements 14
and the backing member 12.
[0133] After the covering elements 14 are fixed to the backing member 12 during manufacture,
the space between the covering elements 14 are filled with mortar. The covering elements
14 are arranged creating the appearance of traditional brickwork and in particular
a stretcher bond pattern. Other patterns, such as Flemish bond or common bond may
be used as desired.
[0134] The frame 10 has a plurality of structural frame members 76 that are connected to
one another to define a frame. The cladding panels 4, 6, 8 are arranged with the frame
10 defining the rear of the cladding panel 4, 6, 8, with the backing member 12 having
a front surface for receiving covering elements 14. No part of the frame 10 is visible
on the front surface and no part of the frame 10 extends to the front surface.
[0135] The frame 10 is mountable to the cladding-panel mounting component 22. The cladding-panel
mounting component 22 may be pre-mounted on the cladding panel 4, 6 before transport
to the building site, or this may be conducted on site.
[0136] The frame 10 has a plurality of structural frame elements 76 extending longitudinally
in a first direction, and a plurality of structural frame elements 76 extending longitudinally
in a second direction, wherein the second direction is perpendicular to the first
direction. The frame 10 has an upper frame element 76a, arranged at or close to the
upper edge of the backing member 12. The frame 10 comprises a lower frame element
76b, arranged at or close to the lower edge of the backing member 12. The upper and
lower frame elements 76a, 76b have apertures 80 that are configured to receive the
fixing elements 58a, 58b of the cladding-panel mounting component 22. The frame 10
further comprises two side frame elements 76c, 76d, arranged at or close to the side
of the backing member 12. The side frame element 76c, 76d extends between the upper
and lower frame elements 76a, 76b.
[0137] Referring now specifically to the flat panel 4, the frame 10 has two intermediate
frame elements 76e located between the two side frame elements 76c, 76d and which
are spaced apart from one another. The intermediate frame elements 76e extend between
the upper and lower frame elements 76a, 76b and they are parallel with the side elements
76c, 76d. The frame 10 further comprises six intermediate frame elements 76f which
are parallel to the top and bottom frame members 76a, 76b and which are arranged extending
from the side frame elements 76c, 76d or from the intermediate frame elements 76e
to provide structural support. The stepped panel 6 has a similar configuration but
a step 78 is built into the frame 10. The step is located centrally between the frame
side elements 76c, 76d. The step 78 extends across the entire height of the panel
6. The backing member 12 is formed from a plurality of separate pieces fitted to the
frame 10 to provide the stepped column. The panel 8 with a soffit surface is described
in more detail below.
[0138] The frame 10 is formed from light gauge steel, but the fixing elements or materials
used to fix the frame elements 76 together may be formed from different materials.
Some of the frame elements may be formed from other materials, such as traditional
steel, but it is preferable that the majority of the frame 10 is formed from light
gauge steel, as this lowers the weight of the panels 4, 6, 8. Advantageously, a panel
spanning an entire floor may be made in this way.
[0139] Referring now to the panel 8 with a soffit surface, the panel 8 has a fascia surface
82 and a soffit surface 84. The panel 8 can therefore be used extending across openings
such as windows, with the soffit surface 84 extending in towards the building opening.
The panel 8 has part of the backing member 12 fixed to one part of the frame 10 defining
a fascia surface 82, and a further part of the backing member 10 fixed to a further
part of the frame 10 defining a soffit surface 84, wherein the soffit surface 84 is
perpendicular to the fascia surface 82. The frame 10 of the panel 8 with the soffit
surface has a soffit frame element 86 that extends along the rear of the backing member
12 that defines the soffit surface 84. The soffit frame element 86 is a C-shaped beam.
[0140] The panel 8 with the soffit surface 84 is mountable to the intermediate mounting
component 24. The mounting means 16 comprises a cladding-panel mounting component
88 for use in suspending a panels from the mounting means 16. The cladding-panel mounting
component 88 is mounted on the frame 10 of the panel 8 with the soffit surface 84.
The frame 10 of the panel 8 with the soffit surface 84 is configured to receive the
cladding-panel mounting component 88. The frame 10 comprises a planar surface 90 for
receiving the cladding-panel mounting component 88. The surface 90 for receiving the
cladding-panel mounting component 88 comprises two apertures 92. The surface 90 for
receiving the cladding-panel mounting component 88 is located at the upper side of
the panel 8.
[0141] The cladding-panel mounting component 88 for suspending the panel 8 has an engagement
means for engaging with the apertures 92. The engagement means is provided by two
hooks 94a, 94b that engage with the apertures 92 of the surface 90 on the panel 8.
Specifically, the cladding-panel mounting component 88 for suspending the panel 8
comprises two spaced apart hooks 94a, 94b that engage with two spaced apart apertures
92 on the panel 90. A planar portion 96 extends perpendicularly from the hooks 94a,
94b and it therefore extends beyond the side perimeter of the panel 8. The cladding-panel
mounting component 88 further has a tab 98, arranged perpendicularly to the hooks
94a, 94b and also perpendicularly to the planar portion 96. The tab 98 abuts an upper
surface of the upper frame element 76a of the panel 8 with the soffit surface 84 when
the cladding-panel mounting component 88 is fitted to the panel 8. The tab 98 can
be fixed to the frame 10 of the panel 8 to secure the cladding-panel mounting component
88 to the panel. The tab 98 has an aperture 100 for receiving a fixing element (not
shown). The cladding-panel mounting component 88 is formed from a single piece of
folded metal.
[0142] The planar portion 96 of the cladding-panel mounting component 88 further comprises
an aperture 102, arranged as an elongate slot, to receive fixing elements (not shown)
to fix the cladding-panel mounting component 88 to the intermediate mounting component
24 or building mounting component 20. The perimeter of the elongate slot 102 comprises
a series of teeth 104 adapted to engage with a corresponding series of teeth (not
shown) on the outer boundary of a washer (not shown). The longitudinal axis of the
slot 102 extends from the upper to lower part of the planar portion 96, thereby providing
adjustability upwards or downwards of the panel 8 with the soffit surface 84 during
installation. Because the planar portion 96 extends beyond the perimeter of the panel
8, this provides visibility of the aperture 102 during installation of the panel 8.
[0143] In use, the building mounting component 20 is first mounted to a building structure
such as a floor slab 18. Next, an intermediate mounting component 24 is fixed to the
building component. A readjustment step may be required wherein the alignment between
the intermediate mounting component 24 and the building mounting component 20 is checked
after engagement between the surface topographies of the components 20, 24, and wherein
the components 20, 24 are disengaged, adjusted and re-engaged.
[0144] Next a cladding-panel mounting component 22, 88 is mounted on the intermediate component
24. Again, a readjustment step may be required wherein the alignment between the cladding-panel
mounting component 22, 88 and the intermediate mounting component 24 is checked after
the washer is inserted into the elongate slot 52a or 52b of the cladding-panel mounting
component 22, and wherein the washer is removed, the alignment between the cladding-panel
mounting component 22, 88 and intermediate mounting component 24 is adjusted, and
wherein the washer is reinserted. Fixing elements such as a nut-and-bolt are used
to fix the building mounting component 20 to the intermediate component 24 and to
fix the intermediate component 24 to the cladding-panel mounting component 22, 88.
[0145] The panel 8 with a soffit surface 84 may be mounted by mounting the cladding-panel
mounting component 88 for suspending a panel from the mounting means 16 initially
on the surface 90 of the panel 8 and then mounting the cladding-panel mounting component
88 on the intermediate component 24. A readjustment step may be required wherein the
alignment between the cladding-panel mounting component 88 and the intermediate mounting
component 24 is checked after the washer is inserted into the elongate slot 102 of
the mounting component 88 of the panel 8 with a soffit surface 84, and wherein the
washer is removed, the alignment between the cladding-panel mounting component 88
of the panel 8 with a soffit surface 84 and the intermediate mounting component 24
is adjusted, and wherein the washer is reinserted.
[0146] Referring to the flat panel 4 and stepped-column panel 6, the panels 4, 6 can be
installed by simply setting the panel 4, 6 onto a cladding-panel mounting component
22 which is mounted on the building structure, such that the fixing elements 56a,
56b extend through the apertures 80 of the lower frame element 76b. It is not necessary
to then use a nut on the fixing element 56a, 56b because the weight of the panel 4,
6 secures the panel to the cladding-panel mounting component 22. The upper end of
the panel 4, 6 can be mounted by either mounting a cladding-panel mounting component
22 on the upper frame element 76b, and then securing the cladding-panel mounting component
22 to a mounted intermediate mounting component 24. Alternatively, the panel 4, 6
could be secured initially at its upper end and then at its lower end if desired.
As the panels 4, 6 extend the entire height of a floor between two floor slabs 18,
a single panel can be installed extending the height of the floor. Adjacent panels
can be sequentially installed to clad the building. The panel 8 with the soffit surface
84 can be installed over openings such as windows. An entire building can therefore
be clad using the cladding system 2, thereby providing the appearance of traditional
brick work on the exterior of the building. Ideally, the panels are prefabricated
in a factory before transport to a site for installation, with the covering elements
14 ideally being fitted to the backing members 12, and spacing between the covering
elements 14 filled with mortar before transportation. The installation may also comprise
fitting waterproof membranes and/or insulation (not shown) between and/or around the
panels 4, 6, 8.
