Description

[0001] SYSTEM FOR THE THERMAL AND ACOUSTIC INSULATION OF WALLS OF BUILDINGS AND METHOD FOR THE REALIZATION OF SAID SYSTEM. DESCRIPTION

[0002] The present invention relates to a system for the thermal and acoustic insulation of walls of buildings, which combines the insulating efficacy of an insulation panel with the robustness and versatility of external tiles. The system is designed to improve the energy efficiency of buildings, reduce environmental noise and simplify the installation process of the system itself.

[0003] It is known that, currently, to acoustically and thermally insulate a building, panels of insulating material, usually polymeric material such as Sintered Expanded Polystyrene (EPS), are arranged on the external and / or internal walls of the building.

[0004] Once this cladding is finished, a plaster is made on its external surface or tiles or other covering elements are arranged to realise an aesthetic finish.

[0005] In case tiles or other covering elements are used, there is the disadvantage, however, that the insulation panels do not guarantee sufficient rigidity to be able to support the tiles themselves.

[0006] Therefore, such tiles must necessarily be fixed directly to the wall of the building, usually by means of metal fixing elements.

[0007] This disadvantageously entails a complication in the installation, and also the definition of thermal and acoustic bridges between the tile and the wall of the building.

[0008] The task of the present invention is to develop a thermal and acoustic insulation system capable of obviating the aforesaid drawbacks and limitations of the prior art.

[0009] In particular, it is an object of the present invention to realise a thermal and acoustic insulation system that is simple to install.

[0010] Even more in detail, it is an object of the present invention to realise a preassembled thermal and acoustic insulation system that makes it possible to simplify and speed up its installation.

[0011] Another object of the invention is the realization of a thermal and acoustic insulation system that avoids defining thermal and acoustic bridges between the external aesthetic finish and the internal wall of the building.

[0012] A further object of the invention is the realization of a thermal and acoustic insulation system that guarantees optimal and greater stability, compared to prior art systems, between the tile and the wall of the building, despite the interposition of the insulation panel.

[0013] The above objects are achieved by a thermal and acoustic insulation system according to claim 1 .

[0014] Further characteristics of the thermal and acoustic insulation system according to claim 1 are described in the dependent claims.

[0015] These objects are also achieved by the method for the realization of the thermal and acoustic insulation system according to claim 12.

[0032] The thermal and acoustic insulation system for walls of buildings of the invention is represented in an isolated manner in figures 1 to 3, where it is indicated overall with 1.

[0033] According to the invention, said thermal and acoustic insulation system 1 comprises an insulation panel 2 made on two levels 2a and 2b staggered from each other, as visible in figures 4 and 5. Furthermore, said thermal and acoustic insulation system 1 comprises an external tile 3 coupled to the aforesaid insulation panel 2, as visible in figures 6 to 8 in isolation. In particular, according to the preferred embodiment of the invention, said external tile 3 is provided, at a first side edge 4a and a second side edge 4b of its internal surface 4, with two notches 5 made with an angle substantially of 45° with respect to the aforesaid internal surface 4. Even more in detail, said notches 5 at 45° are defined starting from said internal surface 4, in a divergent direction towards the outside, as visible in figures 8 and 8a.

[0034] Preferably, said first side edge 4a and said second side edge 4b are two contiguous edges of the tile and, in particular, they correspond to the upper edge and to a side edge of the external tile 3 when the system 1 is correctly installed on the wall of a building.

[0035] Furthermore, the thermal and acoustic insulation system 1 of the invention also comprises “Z”-shaped brackets 6 constituting distinct mechanical elements separable from said insulation panel 2 and fixed to the external tile 3. In particular, as visible in figures 9 and 10, each of these brackets 6 has a first flat element 7 and a second flat element 8, substantially parallel to each other and joined together by an intermediate connecting section 9, so as to define the aforesaid “Z” shape. Furthermore, on the external surface 7a of the first flat element 7, as visible in the aforesaid figures, a tab 10 projecting at 45° and configured to be fixed inside one of the aforesaid notches 5 is defined.

[0036] Even more particularly, as can be seen in figures 9 and 10, according to the preferred embodiment of the invention, on said tab 10 two further cantilevered elements 101 and 102 are obtained with respect to the tab 10, which, when said tab 10 is inserted in one of the notches 5, allow to optimize the coupling by interference between the same tab 10 and the walls of the notch 5, thus improving the coupling between the external tile 3 and the bracket 6.

[0037] It is not excluded that, according to embodiment variants of the invention, the tab 10 is devoid of such cantilevered elements, has a single cantilevered element or has more than two cantilevered elements.

[0038] Advantageously, the fact that these brackets 6 constitute distinct mechanical elements separable from the insulation panel 2, and therefore are not incorporated into the latter, allows the aforesaid brackets 6 to be fixed on at least the first side edge 4a and the contiguous second side edge 4b of the external tile 3. In fact, conversely, if the brackets 6 were incorporated at two contiguous edges of the insulation panel 2, therefore immovable with respect to the latter, it would be impossible to fix the external tile 3 to the brackets 6 at the two contiguous edges 4a and 4b, due to the fact that the inclination of the notches 5 and the tabs 10, at the various edges, take on different directions. Therefore, advantageously, this feature of the invention allows to guarantee greater stability between the external tile 3 and the wall of the building, despite the interposition of the insulation panel 2.

[0039] In this way, each of the brackets 6, when the internal surface 4 of the external tile 3 is coupled to the upper surface 21a of the first level 2a of the insulation panel 2, has the intermediate connecting section 9 positioned close to the side wall of the first level 2a and its second flat element 8 resting by direct contact on the upper surface 21 b of the second level 2b of the insulation panel 2, as visible in figure 2.

[0040] It is not excluded, however, that at each of said first side edge 4a and second side edge 4b of the external tile 3 only one notch 5 or more than two notches 5 are made. Consequently, it is not excluded that only one of these “Z”-shaped brackets 6 or more than two “Z”-shaped brackets 6 are fixed to each of said side edges 4a and 4b.

[0041] This bracket 6, at the second flat element 8, has one or more holes that allow this bracket 6 to be fixed to the wall of the building by means of special fixing elements, for example dowels and screws.

[0042] Consequently, since these brackets 6 are directly fixed to the external tile 3, the latter will also be fixed to the wall of the building. In addition, since the second flat element 8 rests on the upper surface 21b of the second level 2b of the insulation panel 2, the latter will also be fixed to the wall by means of the aforesaid fixing elements and at the same time will not determine thermal bridges between the external tile 3 and the aforesaid wall of the building.

[0043] Even more advantageously, since according to the preferred embodiment of the invention the aforesaid brackets 6 are arranged and fixed on at least two adjacent side edges 4a and 4b of the internal surface 4 of the external tile 3, this allows the latter to be stably associated to the wall of the building, without the risk of unwanted oscillations of the same external tile 3 with respect to the wall of the building.

[0044] According to the preferred embodiment of the invention, moreover, the external tile 3 has at least one notch 5 at 45° with respect to the internal surface 4 also at the third edge 4c of the same internal surface 4, configured to be coupled to the cantilevered edge 11 of the first level 2a of the insulation panel 2 with respect to said second level 2b.

[0045] Also in this case, the notch 5 made at the third edge 4c is defined starting from said internal surface 4, in a divergent direction towards the outside.

[0046] Preferably, said third edge 4c of the tile is the edge diametrically opposite to the first edge 4a and, in particular, it corresponds to the lower edge of the external tile 3 when the system 1 is correctly installed on the wall of a building.

[0047] The system 1 of the invention provides, in this circumstance, a “U”-shaped bracket 12, fixed to the external tile 3 at this third edge 4c. To this end, said bracket 12, as can be seen in figures 11 and 12, is provided with a tab 13 projecting at 45° from the external surface 14a of one of the two flat elements 14, parallel to each other of the same bracket 12, where said tab 13 is configured to be fixed inside the aforesaid notch 5.

[0048] Also in this case, even more particularly, as can be seen in figures 11 and 12, according to the preferred embodiment of the invention, on said tab 13 two further cantilevered elements 131 and 132 are obtained with respect to the tab 13, which, when said tab 13 is inserted in one of the notches 5, allow to optimize the coupling by interference between the same tab 13 and the walls of the notch 5, thus improving the coupling between the external tile 3 and the bracket 12.

[0049] It is not excluded that, according to embodiment variants of the invention, the tab 13 is devoid of such cantilevered elements, has a single cantilevered element or has more than two cantilevered elements.

[0050] The particular “U”-shape allows the bracket 12 to be wedged externally to the cantilevered edge 11 of the first level 2a of the insulation panel 2 when the external tile 3 is coupled to the same insulation panel 2.

[0051] This advantageously allows the coupling between the external tile 3 and the insulation panel 2 to be strengthened and made more stable.

[0052] As for the insulation panel 2, it is made of polymeric material, in particular Sintered Expanded Polystyrene (EPS).

[0053] Furthermore, it is preferably made by injection moulding of the aforesaid polymeric material.

[0054] As far as instead the external tile 3 is concerned, it can preferably but not necessarily be made of porcelain stoneware, tombstones, wooden material, resins, metals, etc.

[0055] A further aspect of the invention consists in the fact that two first longitudinal grooves 15, parallel and spaced apart from each other are made, from edge to edge, on the upper surface 21a of the first level 2a of the insulation panel 2, in such a way as to define two channels 16 passing between the external tile 3 and the insulation panel 2 when said external tile 3 is associated with the aforesaid insulation panel 2.

[0056] It is not excluded that, according to embodiment variants of the invention, at said upper surface 21a only one first longitudinal groove 15 or more than two first longitudinal grooves 15, parallel and spaced apart from each other, can be made.

[0057] In any case, the definition of these channels 16 makes it possible to recirculate air between the external tile 3 and the insulation panel 2.

[0058] Furthermore, according to a different aspect of the invention, second ring-closed grooves 17 are internally made on the same upper surface 21a of the first level 2a of the insulation panel 2.

[0059] The presence of said second ring-closed grooves 17 allows an adhesive material to be applied on said upper surface 21a, to improve the coupling between the insulation panel 2 and the external tile 3, without the risk that said adhesive material may protrude from the same external tile 3 and from the same insulation panel 2.

[0060] Still, according to a different aspect of the invention, third longitudinal grooves 18 transverse between them are made, from edge to edge, on the upper surface 21b of the second level 2b of the insulation panel 2.

[0061] Also in this case, as will be seen shortly, when two or more systems 1 of the invention are installed and wedged between them on the wall of a building, the presence of such third grooves 18 allows to define further through channels, not represented in the figures, which, in this case, in turn, allow to drain any condensation or water that forms between the aforesaid systems 1 coupled and wedged together.

[0062] Finally, as will become clear shortly, the preferred embodiment of the invention provides for the presence of spacer elements 19 arranged at the first side edge 4a and the second side edge 4b of the external tile 3.

[0063] As is clear from what has just been described, the thermal and acoustic insulation system 1 of the invention, and in particular the insulation panel 2 with two levels 2a and 2b staggered from each other, is configured and shaped to allow the same insulation panel 2 to be fixed to the wall of a building, flanked to and interlocked with several systems 1 , in particular with several insulation panels 2, always according to the invention.

[0064] In particular, in this case the spacer elements 19 advantageously allow to keep the various external tiles 3 of two flanked systems 1 precisely and regularly spaced apart along their edges, and also allow to keep these external tiles 3 coplanar with each other.

[0065] Furthermore, the fact that the various systems 1 of the invention are arranged adjacent to and wedged between them on the wall of a building allows to define a continuity for the entire wall both of the first through channels 16 defined by the aforesaid first grooves 15, and of the aforesaid second through channels defined by the third longitudinal grooves 18 made on the upper surface 21b of the second level 2b of the insulation panel 2.

[0066] As mentioned above, the method for assembling a thermal and acoustic insulation system according to the invention is also part of the invention.

[0067] In particular, the method of the invention provides for:

[0068] - preparing a mould configured for the realization of the insulation panel 2;

[0069] - injecting the polymeric material into the mould for moulding the insulation panel 2;

[0070] - extracting the insulation panel 2 from the mould, after consolidation of the polymeric material;

[0071] - preparing the external tile 3;

[0072] - realizing, at least at a first side edge 4a and a second side edge 4b of its internal surface 4, at least one notch 5 with an angle substantially of 45° with respect to said internal surface 4;

[0073] - fixing for each of the notches 5 a “Z”-shaped bracket 6, by fixing inside the notch 5 the tab 10 projecting at 45° from the same bracket 6;

[0074] - coupling the external tile 3 to the insulation panel 2 so that each bracket 6, when the internal surface 4 of the external tile 3 is coupled to the upper surface 21a of the first level 2a of the insulation panel 2, has the intermediate connecting section 9 positioned close to the side wall of the first level 2a and also has its second flat element 8 resting by direct contact on the upper surface 21b of the second level 2b of the insulation panel 2.

[0075] Based on the above, it is understood that the thermal and acoustic insulation system of the invention achieves all the above objects.

[0076] In particular, the object of realizing a thermal and acoustic insulation system that is simple to install has been achieved.

[0077] Even more in detail, the object of the present invention to realize a preassembled thermal and acoustic insulation system that allows to simplify and speed up its installation is achieved.

[0078] Another object achieved by the invention is the realization of a thermal and acoustic insulation system that avoids defining thermal bridges between the external aesthetic finish and the internal wall of the building.
