[0001] The invention relates to a panel for an outer wall, comprising an assembly of two
flat parallel plates separated by a peripheral profile, provided with a peripheral
edge of a moisture and vapour-tight adhesive and at least one recess provided between
the plates in the peripheral edge for at least partially receiving a fastening element
therein.
[0002] Such an outer wall panel is known and is applied in so-called curtain walls.
[0003] The known outer wall panels are normally manufactured from two parallel glass plates
which are separated from each other by a hollow aluminium peripheral profile in which
a desiccant is arranged. The two glass plates and the peripheral profile are joined
together to form a double-walled glass outer wall panel using a moisture and vapour-tight
mastic edge.
[0004] The known outer wall panels can be fastened in known manner against for instance
aluminium vertical and horizontal profiles of an outer wall. Use is herein made in
known manner of a T-shaped fastening element which consists of two transverse wings
which are rotated into the respective recesses of two outer wall panels lying adjacently
or above, and a central hollow middle part through which a screw can be inserted which
can be screwed into a vertical or horizontal profile.
[0005] Outer wall panels are known in which the recess for receiving a T-shaped fastening
element is formed onto the peripheral profile of the panel. Such a panel is expensive,
and moreover has the drawback that the minimal distance between the plates required
for the recess is too large in respect of the desired insulating properties.
[0006] It is an object of the invention to provide an outer wall panel which can be fastened
in simple manner to an outer wall, which panel is provided with at least one recess
in the peripheral edge, in which panel the plates can be adhered in moisture and vapour-tight
manner at a mutual distance which is optimal in respect of the desired insulating
properties of the panel.
[0007] It is a further object to provide such a panel that can be produced in simple manner.
[0008] These objectives are achieved, and other advantages gained, with a panel of the type
specified in the preamble, wherein according to the invention the recess is provided
by an elongate holder element which can be countersunk in the peripheral edge substantially
clear of the peripheral profile and which is formed substantially by an elongate bottom
part, two opposite long wall parts and two opposite short wall parts.
[0009] During the production of the outer wall panel such a holder element can be pressed
between the plates into the peripheral edge formed by the adhesive as long as this
adhesive has not yet cured.
[0010] In an embodiment of a panel according to the invention the bottom part is flat, the
opposite long wall parts extend perpendicularly thereof and the opposite short wall
parts extend obliquely and transpose gradually into the bottom part.
[0011] The gradual transition between the short wall parts and bottom part gives the holder
element a trough form which facilitates pressing of the holder element into the adhesive
that has not yet cured.
[0012] For strengthening thereof the holder element is preferably provided on its top side
with a flat peripheral edge extending transversely of the wall parts.
[0013] In order to prevent the adhesive being pressed out by the holder element between
the bottom thereof and the peripheral profile, in an advantageous embodiment the holder
element is provided on its bottom part with foot elements.
[0014] Such a holder element can be pressed up to a determined depth into the adhesive,
whereafter it supports with the foot elements on the edge profile.
[0015] In another embodiment of a panel according to the invention the holder element is
provided with longitudinal ribs on the sides of the long wall parts remote from each
other.
[0016] Such longitudinal ribs serve for fixation of the holder element immediately after
arrangement thereof in the peripheral edge, during the period that the adhesive has
not yet cured.
[0017] A holder element in a panel according to the invention can be manufactured from any
suitable material, from a metal as well as from a plastic material.
[0018] The invention further relates to a holder element for an above described outer wall
panel.
[0019] The invention will be elucidated hereinbelow on the basis of an exemplary embodiment
with reference to the drawings.
[0020] In the drawings
Fig. 1 shows in cross-sectional view a detail of an outer wall with parts of two adjacent
coupled wall panels according to the invention and a horizontal profile in a vertical
section through a pair of corresponding holder elements and a T-shaped fastening element,
and
Fig. 2 is a perspective view of an embodiment of a holder element for an outer wall
panel as shown in fig. 1.
[0021] Corresponding components are designated in the figures with the same reference numerals.
[0022] Fig. 1 shows a detail of an outer wall with two outer wall panels 1, each assembled
from two parallel glass plates 2, 3 which are separated from each other by a hollow
aluminium peripheral profile 4 and which are adhered to each other by a peripheral
edge 5 of a moisture and vapour-tight adhesive. Panels 1 are provided with a number
of holder elements 6 according to the invention, of which are shown a bottom part
7, long wall parts 8 extending therefrom, feet 9 supporting on peripheral profiles
4, and an edge 10. Using a T-shaped fastening element 13 the panels 1 are indirectly
fastened to a horizontal profile 11, separated therefrom by a profile 12 of a compressible
neoprene plastic material. The T-shaped fastening element 13 consists of two transverse
wings 14 which are rotated into the respective holder elements 6 of outer wall panels
1, and a central hollow middle part through which protrudes a screw 15 which is screwed
into a screw channel 16 formed for this purpose in horizontal profile 11. The (in
this embodiment horizontal) gap between outer wall panels 1 is sealed by a strip 17
of a flexible material.
[0023] Fig. 2 is a perspective view of a holder 6 which is shown in fig. 1 in the section
along the broken line I-I, having in addition to the above-mentioned components the
oblique short wall parts 18 transposing gradually into the bottom 7, longitudinal
ribs 19 on the long wall parts 8, and a flat peripheral edge 10 extending transversely
of wall parts 8, 18.
