FIELD OF THE INVENTION
[0001] This invention pertains to the building sector and relates in particular to external
thermal façade insulation systems consisting of insulation panels with ceramic tiling
or plating.
BACKGROUND OF THE INVENTION
[0002] Among the different types of cladding which an external thermal façade insulation
system can have are those consisting of ceramic tiles and plates which simulate facing
bricks. In all systems, the ceramic pieces are directly glued to the insulation panels
such that, if the adhesive were to fail, the pieces could become detached and fall
down, with the resulting risk of causing personal injuries. Thus, this kind of ceramic
cladding is usually used in buildings which are one or two-storey high at the most.
As set out below, the insulation panel which is the object of this invention helps
to satisfactorily solve the safety problem posed by known ceramic claddings, for which
it makes use of and improves the system for the mechanical joining of corrugated synthetic-foam
panels and ribbed ceramic tiles described in the same applicant and inventor's patent
with publication number
ES2457992. Hence, this new panel constitutes an industrial development derived from said patent.
DISCLOSURE OF THE INVENTION
[0003] The panel (1) of the invention will be preferably manufactured in expanded polystyrene,
although it can also be made of any other synthetic foam suitable for the intended
use. The panel is configured in the shape of a plate crisscrossed by a series of parallel
main channels (2), having a dovetail cross section, and of other secondary channels
(3) arranged transversely to the main channels. The parallel main channels are wider
since they have to house the flanges or ribs (9) which the ceramic tiles have plus
the adhesive mortar which surrounds them, whereas the secondary channels (3) are narrower
because they only have to hold a thin partition of adhesive mortar. The secondary
channels (3) are connected with the main channels (2) in order to assemble as a whole
a reticular, adhesive mortar structure which multiplies the anchoring and joining
effect among the different pieces that make up the insulation system. The edges of
the channels take on markedly rounded shapes so as to facilitate the dispersion of
the adhesive mortar that is displaced when the flanges or ribs (9) of the ceramic
tiles (7) or plates (6) are inserted in the main channels (2) of the panels. From
the sides of the main channels of the panel emerge projections (4) that support the
ceramic pieces aligned with the panel. Other, additional characteristics are that
the bottom (8) of the main channels may have a bulging or convex shape, which permits
expanding the depth of the footprint - to boost the anchoring effect of the dovetail
- without having to increase the average thickness of the adhesive mortar layer as
a result, and also that some special panels (1.2) may have a fluted edge (10) to extend
the grooves in the main channels at inside corners.
[0004] In an optional manner, the edges of the panels may have grooves for attaching hidden
staples; in addition, the back thereof may be embossed or grooved in order to increase
the surface in contact with the façade wall adhesion mortar.
DESCRIPTION OF THE DRAWINGS
[0005]
Figure 1 shows a standard panel (1) in perspective, crisscrossed by the main channels
(2) and the secondary channels (3), plus the protruding flanges (4) for aligning and
supporting the ceramic pieces; additionally, two enlarged detailed views A and B of
the dovetail cross sections of the respective channels are included. Detailed view
A corresponds to the narrow secondary channels and detailed view B corresponds to
the wider main channels and the convex bottom (8).
Figure 2 shows a panel (1) in perspective clad with ceramic plates (6) simulating
facing bricks. A cut has been made in the cladding materials to render the flanges
or ribs (9) of the ceramic plates and the intermediate adhesive mortar layer (5),
which coheres the entire assembly whilst filling the joints between plates, visible.
Figure 3 is a typical cross section of a panel (1) with a cladding of ceramic plates
(6) and the intermediate adhesive mortar layer (5) which coheres all the pieces.
Figure 4 shows a panel (1) in perspective with a large-sized ceramic tile (7) attached
thereto. A cut has been made in the cladding materials to render the flanges (9) of
the tiles and the intermediate adhesive mortar layer visible.
Figure 5 is a typical cross section of a panel (1) with an attached ceramic tile (7)
and the intermediate adhesive mortar layer (5).
Figure 6 shows a special corner panel (1.2) with groove extension channels (10) on
one of its edges.
PREFERRED EMBODIMENTS
[0006] In a preferred embodiment - with an 'in situ' execution of the work, the naked insulation
panels are glued to the façade wall of the building with adhesive mortar of the same
type and quality as that used in any other external insulation system having expanded
polystyrene panels. The panels must then be secured by means of mechanical fasteners,
which may consist in well-known devices such as hidden staples and/or plastic-shank
wall plugs with a racket-shaped head. Next - using a brick trowel, the main channels
of the panels are filled up to the edge with an adhesive mortar of a doughy consistency
and, afterwards, the ceramic tiles or plates are stuck such that the longitudinal
flanges or ribs thereof become submerged in the adhesive mortar. As the ribs sink
in the adhesive mortar, the latter is displaced and forced to flow in all directions,
thereby filling the secondary channels whilst forming a thin intermediate layer between
the surface of the panel and the ceramic pieces. An intelligent design of all involved
pieces which takes into account the ideal amount of the volume of displaced adhesive
mortar will even allow for there to be enough excess mortar left to fill up the exposed
joints between ceramic pieces. The flanges which emerge from the side faces of the
main channels of the panel help to centre and support the ceramic pieces in their
right position during the mortar setting time. The final result is a façade insulated
and clad with ceramic tiles or plates which, under normal conditions of use, cannot
become detached since they are attached by means of an efficient joining system of
both a chemical and a mechanical nature.
[0007] In another preferred embodiment, it would also be possible to prefabricate the panels
in a workshop, with the tiles or plates already assembled and glued to the insulation
panels, their placement being then adapted to the characteristics in question.

in expanded polystyrene or any other type of synthetic foam, by moulding or machining,
with a design comprising a ceramic panel and tile joining system, crisscrossed by
main channels (2) and wherein the flanges (9) of the ceramic tiles (7) or plates (6),
plus the adhesive mortar (5) which surrounds them, are housed, characterised in that it is additionally configured with other, narrower secondary channels (3) connected
in a transverse arrangement with the main channels (2), and in that the edges of the channels have a markedly rounded profile to facilitate the free
dispersion in all directions of the adhesive mortar (5) which sits between the panel
and the ceramic tiles, and in that from the side faces of the main channels (2) emerge flanges (4) as devices to support
the ceramic tiles aligned with the insulation panel during adhesive mortar setting
time.

claim 1, characterised in that the bottom of the main channels (2) has a convex shape (8).
3. A panel for external thermal façade insulation with ceramic cladding according to
claim 1, characterised in that one of its edges is fluted (10) to extend the groove of the main channels (2) at
the inside corners formed where two panels meet.
