STATE OF THE ART

How?? known, in the building sector there are modular panels for the creation of insulating coats in existing buildings, in order to improve the thermal and possibly acoustic performance of the buildings themselves.

Known types of panels are available in a plurality of of insulating materials including, for example, wood fibre, expanded cork, rock or glass wool, expanded polystyrene, polyurethane, etc.

According to a known technique, the panels are first secured to the walls to be insulated by means of adhesive substances and/or mechanical fastening systems, placing them side by side so as to obtain a substantially continuous covering. Subsequently, the panels are covered with plaster, in such a way as to obtain the continuity surface aesthetics.

According to a known variant, the insulation is made outside the building, with the advantage of having limited dimensional constraints and allowing the use of very thick panels, which correspond to equally high insulation performances.

The variant just mentioned pu? lead to the inconvenience of requiring the assembly of an external scaffolding which allows for the plastering to be carried out and which must be removed at the end of the work, consequently increasing the times and overall costs of installation.

Does the aforementioned scaffolding have the further possible drawback of occupying public land, requiring the obtainment of the relative authorizations from the authorities? premises, with a consequent increase in bureaucratic obligations and related costs.

In some cases, before plastering, any cracks present between the panels are sealed with a sealing material to prevent water infiltration into the insulation.

The sealing operation just mentioned increases the drawbacks already mentioned, increasing the complexity? and the time needed to make the coat.

PRESENTATION OF THE INVENTION

The object of the present invention is to at least partially overcome the drawbacks of the prior art mentioned above.

In particular, ? The purpose of the invention is to create a modular system for the thermal insulation of buildings which simplifies the process for making an external coat with respect to the previously described prior art, reducing the time required for this process.

The above aims are achieved by a modular system according to the main claim.

Further detailed characteristics of the invention are specified in the relative dependent claims.

According to a first aspect, the invention concerns a modular system comprising a plurality of of panels that can be placed side by side in both horizontal and vertical directions and incorporating gaskets which, by positioning themselves in reciprocal contact, prevent water infiltration through the respective interspaces.

According to a further aspect of the invention, the upper and lower edges of the panels have shapes suitable to prevent water infiltrations towards the wall.

According to a further aspect of the invention, the panels comprise guide elements to ensure correct alignment between the panels and, therefore, between the aforementioned gaskets, both during assembly and subsequently, as well as during assembly. to ensure effective water tightness.

According to a further aspect of the invention, the panels comprise fixing elements to facilitate assembly of the insulation.

Executive variants of the invention provide for drainage profiles interposed between adjacent panels and shaped in such a way as to facilitate the drainage of the water towards the outside.

Further embodiments of the invention envisage providing the panels with a finishing layer, in particular plastering, during production.

Advantageously, the ease? installation of the modular system of the invention allows to reduce the time for the construction of the insulation and, therefore, the relative costs.

Still advantageously, the modular system of the invention makes it possible to avoid plastering and sealing, consequently avoiding the need for plastering and sealing. of scaffolding and the relative authorisations, except those strictly necessary for the means for handling the panels.

The panels 2?, 3?, 4? are they completely analogous to panels 2, 3, 4 and, therefore, also to them? applicable how much will come? described below.

It should be noted from now on that, in Figs. 1 and 6, some panels are represented in transparency, indicating only the borders in dashed line, to facilitate the visualization of the underlying details.

Preferably and as can be seen for example in the section of Fig. 4, each panel 2, 3, 4 comprises a first support layer 15 made of rigid material, for example wood.

Still preferably, each panel 2, 3, 4 comprises a second layer 16 arranged between the first support layer 15 and the external face 2b, 3b, 4b and made of a material which has a thermal insulation coefficient per unit? thicker than that of the aforementioned rigid material, for example wood fibre, expanded cork, rock or glass wool, expanded polystyrene, polyurethane, etc.

Still preferably, each panel 2, 3, 4 comprises a third finishing layer 26, for example of plaster, which defines the external face 2b, 3b, 4b of the respective panel. Preferably, the third finishing layer 26 is prepared on the panels directly in the factory during production. Advantageously, the presence of the third finishing layer 26 incorporated in the panels avoids the final plastering operation.

Each panel 2, 3, 4 ? peripherally delimited by respective edges 5, 6, 7 which, preferably, are configured so as to define a generally rectangular perimeter for the panel.

A first panel 2 ? arranged below a second panel 3 and has a first edge portion 5 facing upwards and facing a second edge portion 6 facing downwards of the second panel 3, as can be better seen in Fig. 4. The aforementioned two edge portions 5 and 6 extend longitudinally according to corresponding first X directions, preferably horizontal, and have mutually conjugate and uniform sections according to the aforementioned first X directions.

In this way, the modular system 1 comprises a multiplicity? of panels 2, 3 superimposed on each other in series so as to form a first column which covers the wall P for the whole height or for a part thereof.

Also, preferably, a third panel 4 ? which can be positioned laterally to one of the panels 2 and/or 3 in the aforementioned operating configuration, so that a third edge portion 7 of the third panel 4 which delimits it according to a respective second direction Y, preferably vertical, incident on the first direction X faces a corresponding third edge portion 7 of panel 2 or 3 developed according to the same second direction Y.

Still preferably, ? is there a plurality? of the aforementioned third panels 4, each of which is positioned laterally to each of the panels 2 and 3 described above, in such a way as to define a further column alongside the aforementioned first column.

Evidently, the use of a plurality? of the aforementioned columns placed side by side allows the wall P to be covered over the entire width.

It should be noted from now on that the distinction of the panels into first, second and third, and the relative numbering, has the sole purpose of distinguishing the panels on the basis of their reciprocal position, in order to describe more of them. clearly the geometric and functional aspects, but does not intend to set further limitations on the shapes of the panels themselves. For example, two or more of the panels 2, 3, 4 can be similar to each other, or even identical and interchangeable. In the latter case, what is described below? to be understood as applicable to any of the aforementioned similar or identical panels.

Preferably, each panel 2, 3 comprises a respective first gasket 8, 8? associated with the respective edge portion 5, 6 and developed according to the corresponding first direction X. The first gasket 8, 8? ? configured in such a way as to be in contact with the first gasket 8, 8' of the other panel when the panels 2, 3 are in the operative configuration.

Advantageously, when the panels are in the operative configuration, the first gaskets 8, 8? described above are arranged in mutual contact cos? to prevent the penetration of water from the outside towards the wall P through a first cavity 22 defined between the edge portions 5 and 6, avoiding the need to to seal the cavity itself.

It is hereby specified that, in the present description, the references to water which can penetrate from the outside of the system 1 towards the wall P are to be understood in a broad way, to include rainwater or spray water, water originating from the condensation of humidity environmental, and what? Street.

Still advantageously, the gaskets 8, 8? they ensure airtightness from inside the building to the outside of the panel, improving insulation performance.

Preferably and as can be seen in detail in Fig. 4, the first edge portion 5 of the first panel 2 and the second edge portion 6 of the second panel 3 comprise respective first surfaces 5a, 6a which have an upward slope, according to a direction Z orthogonal to the plane defined by the panels 2, 3 and according to an orientation which goes from the external faces 2b, 3b towards the internal faces 2a, 3a, when the panels 2, 3 are in the operative configuration.

Consequently, a portion of the first surface 5a of the first panel 5 is larger. next to the respective internal face 2a according to the orthogonal direction Z is it more? up compared to its portion pi? close to the respective external face 2b. The same occurs for the first surface 6a of the second panel 6 with respect to the corresponding internal 3a and external 3b faces.

Advantageously, the aforementioned first surfaces 5a, 6a hinder the ascent of water from the external faces 2b, 3b of the panels 2, 3 towards the wall P and, therefore, help to hinder the passage of water between the panels themselves and the assembly time .

Preferably, the angle a formed by the first surfaces 5a, 6a with respect to the orthogonal direction Z? about 50? or, anyway, ? preferably between 40? and 50?. Advantageously, the first surfaces 5a, 6a configured as just described facilitate the correct positioning between the panels 2, 3, as they facilitate the sliding of the second panel 3 on the first panel 2 according to the orthogonal direction Z during the vertical descent of the second panel 3, how will it come? described later.

Advantageously, the presence of two first gaskets 8, 8? on each panel increases water and air tightness. In particular, the water tightness is performed above all by the most? external, while those pi? internal perform above all the function of air tightness.

Preferably, each of the aforementioned first edge portion 5 and second edge portion 6 comprises a corresponding second surface 5b, 6b which extends from one side of the corresponding first surface 5a, 6a according to the aforementioned orthogonal direction Z with a slope lower than the slope of the first surface 5a, 6a. In the operative configuration, the aforementioned second surfaces 5b, 6b face each other.

Advantageously, the aforementioned second surfaces 5b, 6b contribute to a better water tightness and, moreover, they facilitate the precise alignment between the two panels 2, 3 in the orthogonal direction Z, as well as the stability? of mutual mating. Still advantageously, the second surfaces 5b, 6b offer space for housing the first gaskets 8, 8?, as will be better described later.

Preferably, the second surfaces 5b, 6b are oriented so as to be generally horizontal when the panels 2, 3 are in the operating configuration, advantageously helping to facilitate positioning and stability? coupling between the panels themselves.

Still preferably, each edge portion 5, 6 comprises a further of the aforementioned second surfaces, indicated by 5c, 6c, which extends from the opposite side of the first surface 5a, 6a according to the orthogonal direction Z, also with a lower slope to that of the first surface 5a, 6a. The presence of two second surfaces on each edge portion 5, 6 and arranged opposite to the respective first surface 5a, 6a increases the advantages highlighted above.

Preferably, each of the aforementioned first gaskets 8, 8? ? associated with a corresponding second surface 5b, 5c, 6b, 6c. Advantageously, the positioning just described, in virtue? of the reduced slope of the second surfaces 5b, 5c, 6b, 6c, favors an optimal contact between the pairs of the first gaskets 8, 8' facing each other and, therefore, the seal between the two panels 2, 3.

Still preferably, the first surfaces 5a, 6a and the second surfaces 5b, 5c, 6b, 6c described above are formed on the first support layer 15 of the respective panel 2, 3.

Preferably, the second panel 3 also comprises one or more? bodies of comparison 10, of which one? visible in Figs. 2 and 4, which extend from the internal face 3a so as to protrude beyond the second edge portion 6. In this way, in the operative configuration, the abutment bodies 10 are oriented downwards and are arranged close to the internal face 2a of the underlying first panel 2.

Advantageously, the protruding portion of the aforesaid abutment bodies 10 faces the first surface 6a thus? that they delimit, on respective opposite sides, a channel which couples with the first edge portion 5 of the first underlying panel 2 so as to guide the alignment of the two panels 2, 3 according to the orthogonal direction Z during assembly, facilitating what? also the correct reciprocal positioning of the first gaskets 8, 8?.

Preferably, each abutment body 10 ? in the form of a plate, preferably metallic, which is constrained to the inner face 3a of the second panel 3 by means of screws or other connection means, not shown in the drawings but per se? Note.

Preferably, the protruding portion of each abutment body 10 is inclined so as to diverge from the internal face 3a towards the wall P. Advantageously, the divergent shape just mentioned facilitates the coupling of the second panel 3 to the first panel 2.

As regards the third lateral edge portions 7 of the panels, they preferably comprise respective grooves 7a, two of which are visible in the detail of Fig. 3 for the two panels 2 and 3. The grooves 7a are developed according to the second directions Y and configured in such a way as to face each other when the panels 2, 3, 4 are in the operating configuration, to define corresponding channels 11 which, preferably, extend along the entire length of the panels 2, 3, 4 according to the second direction Y.

? there is also an alignment bar 12 which can be inserted in the aforementioned channel 11 to advantageously make the panels monolithic once installed, thus to increase the stability? of the coating. As an equally advantageous consequence, the alignment bar 12 allows the two third edge portions 7 to be kept mutually aligned according to the orthogonal direction Z, thus to ensure that the two panels 2, 3, 4 mutually placed side by side match according to the aforementioned direction.

Preferably, the panels 2, 3, 4 are configured in such a way that, in operative configuration, the respective channels 11 are vertically aligned. This ? represented in Fig. 4, where the aforementioned alignment bar 12 ? shown cut to allow the first surfaces 5a, 6a to be seen. In reality?, the 12 bar can? have a sufficient length to affect both panels 2 and 3, or can there be more? alignment bars 12 stacked vertically in channels 11 and in mutual contact at their respective ends.

The second seal 9, 9? ? configured in such a way as to be in contact with a corresponding second gasket 9, 9' associated with the other panel 2, 3, 4 when the panels are in the operative configuration.

Advantageously, the second seals 9, 9? ensure water and air tightness through a second gap 23 included between the third edge portions 7 facing each other, further favoring the overall seal of the modular system 1. Similarly to the first gaskets 8, 8?, also in the case of the second gaskets 9, 9? the watertightness is ensured above all by the external seals, while the internal ones mainly perform an airtight function.

Preferably, the second gasket 9, 9'? connected in a continuous way with a corresponding one of the aforementioned first gaskets 8, 8' to, advantageously, ensure continuity? also on the corner of the corresponding panel.

Still preferably, each panel comprises two of the aforesaid second gaskets 9, 9?, arranged on two respective mutually opposite sides with respect to the groove 7a.

Still preferably, the grooves 7a and, possibly, the surfaces to which the second gaskets 9, 92 are associated, belong to the first support layer 15 of the panels 2, 3, 4, with the same advantages already remember earlier.

Preferably, each first gasket 8, 8? and second gasket 9, 9? ? a respective elastomeric element developed in a longitudinal direction with a uniform cross-section, of the type commonly used for sealing door and window frames. Furthermore, preferably, each edge portion 5, 6, 7 defines a corresponding groove 24 developed according to the respective longitudinal direction X, Y, which is indicated in dotted lines in Fig. 2 and more. in detail in Fig. 3, which accommodates a mating edge of the gaskets 8, 8', 9, 9' so that the opposite edge of the gasket remains protruding from the edge portion 5, 6, 7 to be compressed against the gasket of the tiled panel.

Still preferably, each second gasket 9, 9? ? connected to the corresponding first seal 8, 8? in such a way as to form a sharp edge, with the advantage of improving water tightness at the tops of the panels. The aforementioned corner can? be obtained, for example, by cutting the gaskets 8, 8?, 9, 9? so that each of the two surfaces that define the ends? of each gasket form an angle of 45? with respect to the longitudinal direction of the gasket itself, so as to match the end surface? of the adjacent gasket arranged orthogonally to the first.

Still preferably, the modular system 1 comprises a plugging profile 13, preferably made of bent sheet metal, visible in particular in Figs. 3 and 5. The infill profile 13 ? configured to be coupled to the aforementioned second interspace 23 so as to close it, so to further prevent the ingress of water.

Preferably, the plugging section 13 is provided with a first longitudinal edge 13a which can be inserted into the second interspace 23 and configured so as to delimit a channel 14 which runs parallel to the second direction Y of the third edge portions 7. Advantageously, the aforementioned channel 14 facilitates the drainage of water which may accumulate in the second cavity 23.

Still preferably, the closing profile 13 is inserted in a portion of the second cavity 23 defined by the second layer 16 of the panels 2, 3, 4, ie the insulating layer. This last layer has a certain yield which allows the insertion of the infill profile 13 into the second cavity 23 by interference, favoring stability. coupling and water tightness.

Still preferably, the first longitudinal edge 13a is folded back on itself so as to define an enlarged portion to facilitate the insertion of the profile 13 by interference into the interspace 23 and increase the stability? of mating.

Preferably, the infill profile 13 comprises a second longitudinal edge 13b opposite the aforementioned first longitudinal edge 13a and with a width greater than the width of the second interspace 23, so that, when the panels 2, 3, 4 are in the operating configuration and the first longitudinal edge 13a of the infill profile 13 is inserted in the second cavity 23, the second longitudinal edge 13b rests on the external faces 2b, 3b, 4b of the pair of panels 2, 3, 4 which define the second cavity 23 itself to cover it, to the advantage of the aesthetic result of the whole.

The embodiment variant shown in Figs. 6 and 7 differs from the previous one in that the third edge portions 7 of the panels are configured in such a way that the second gap 23 has an enlarged portion 23a adjacent to the external face 2b, 3b, 4b. Furthermore, ? there is a different infill profile, indicated with 13', which has two opposite and mutually facing first longitudinal edges 13a', connected by an intermediate portion 13b' the width of which ? smaller than the width of the enlarged portion 23a. The profile 13' just described is inserted by interference into the portion 23a of the cavity so that the first two longitudinal edges 13a' are arranged in contact, respectively, with the two mutually facing surfaces which delimit the portion of cavity 23a in such a way to be defined two drainage channels 14 parallel to each other, similar to the one described above for the previous infill profile 13.

Preferably, the modular system 1 also comprises a drainage profile 17, visible in detail in Fig. 4. The profile 17, preferably made of bent sheet metal, is secureable to the first edge portion 5 of the first panel 2 or to the second edge portion 6 of the second panel 3 in such a way that one of its first longitudinal edges 17a protrudes beyond the external face 3b of the panel 3 itself. Advantageously, the first longitudinal edge 17a intercepts any water that may drip onto the external face 3b of the panel 3 and carries it towards the outside of the panel itself, preventing it from entering the first interspace 22.

Preferably, the first longitudinal edge 17a is folded down cos? to increase the stiffness of the profile 17 and guide the conveyance of the water towards the outside.

Still preferably, the first longitudinal edge 17a is further folded upwards so as to define a channel 18 which runs parallel to the first direction X of the second edge portion 6, both to convey the water towards one side of the panel 3, and to further increase the stiffness of the profile itself .

Still preferably, the drainage profile 17 has a second longitudinal edge 17b, opposite to the first, folded upwards, which can? be wedged into the interface between the support layer 15 and the insulating layer 16 of the panel to, advantageously, contribute to the stable connection of the section bar 17 to the panel itself, while avoiding longitudinal deformation thereof.

As regards the fixing of the panels 2, 3, 4 to the wall P, this preferably takes place by means of one or more? support bars 19, visible for example in Fig. 1, which can be secured to the wall P. Preferably, the support bars 19 are wooden prismatic elements. In the preferred embodiments shown in the drawings, the support bars 19 are oriented vertically, but in embodiments of the invention they could be oriented horizontally.

The first panel 2 ? also equipped with one or more fixing bodies 20 secured to the internal face 2a of the panel itself, so that a portion of each fixing body 20 protrudes beyond the first edge portion 5 upwards when the panels are in the operative configuration. Preferably, each fastening body 20 is a metal plate constrained to the inner face 2a by screws, nails or other equivalent fastening means.

Are there also connection means, not shown in the drawings but per se? known, to secure the fastening body 20 to a corresponding support bar 19. The connection means can comprise screws, nails or other equivalent fastening means, which are inserted into corresponding through holes of the aforementioned protruding portion of the fastening body 20.

According to a variant embodiment not shown in the drawings, the first panel 2 comprises a recess defined on the internal face 2a to house each fastening body 20 in such a way that it does not protrude from the face itself according to the orthogonal direction Z. In this way, advantageously, ? possible to arrange the internal face 2a substantially in contact with the support bar 19 so as to limit the distance of the panel 2 from the wall P.

Preferably, the first panel 2 comprises two or more? of the aforementioned fixing bodies 20, mutually spaced along the first edge portion 5 according to the first direction X to allow the connection of the panel to as many support bars 19.

Obviously, the aforesaid fixing bodies 20 can be present in one or more? of the other panels 2, 3, 4 which make up the modular system 1. Also in this case, each fixing body 20 protrudes beyond the upper edge of the respective panel 2, 3, 4 so as to allow the fixing of the panel itself to a corresponding support bar 19.

Operationally, the lining of the wall P with the modular system 1 preferably takes place as follows.

First of all, a platform 25 is arranged at the foot of the wall P, which acts as a horizontal base for resting the lower panels.

Subsequently, a series of support bars 19 are secured to the wall P, for example by means of screws or nails, preferably oriented vertically.

A first series of panels 2, 4 is then positioned resting on the aforementioned platform 25 and placed side by side according to the horizontal direction, fixing the respective fixing bodies 20 to the support bars 19. The third edge portions 7 of the panels 2 , 4 are brought side by side so as to bring the second gaskets 9, 9' into reciprocal contact, so to define the second gaps 23.

Subsequently, the alignment bars 12 are inserted into the channels 11 defined by each pair of mutually adjacent panels 2, 4, as shown in Fig.5.

If envisaged, the plugging sections 13 or 13' are then inserted into the second interspaces 23 or into their enlarged portions 23a.

A second series of panels 3, 4 are then lowered vertically onto the first series of panels and in turn secured to the support bars 19 by means of the respective fixing bodies 20, so as to be placed side by side and spaced from the underlying panels by means of the first gaskets 8, 8' to define the first gaps 22.

This last operation ? facilitated by the inclination of the first surfaces 5a, 6a, which act as many slides, and by the presence of the abutment bodies 10, which during their descent guide the panels 3, 4 according to the orthogonal direction Z so as to bring them into alignment with the corresponding panels 2, 4 below.

Preferably, the upper panels 3, 4 are fixed to the wall P so as to define, with the lower panels 2, 4, a first interspace 22 of substantially uniform width and suitable for compressing the gaskets 8, 8? against each other so that they perform their function optimally. The same occurs for the second gaps 23 defined between the side edges of the panels 2, 3, 4.

If the drainage sections 17 are used, they are preferably secured to the upper panels 3, 4 before lowering the latter onto the underlying panels. In a variant embodiment, the drainage profiles 17 can be secured to the first edge portions 5 of the lower panels 2, 4 before lowering the upper panels 3, 4.

After the second series of panels have been fixed to the wall P, the alignment bars 12 are inserted between them, similarly to what has been described above for the first series of panels.

The procedure continues with the possible installation of further series of panels which are superimposed on the previous ones until the cladding of wall P is completed.

The entire procedure described up to now pu? be carried out using a lifting device, such as a crane, without the need? of scaffolding.

The presence of the finishing layer 26 incorporated in the panels also avoids the need for of final plastering.

Although the procedure described provides for the laying of the panels in a succession of horizontal layers superimposed on each other, it is not? excluding that it is possible to proceed in a different way, placing the panels in a succession of vertical columns side by side.

From what has been described above, it is understood that the modular system of the invention achieves the set objects.

In particular, the particular geometric configuration of the panels facilitates their mutual alignment, making the method of manufacturing the cladding particularly simple and rapid with respect to the prior art.

Furthermore, the presence of the gaskets avoids the need for external sealing. Furthermore, the presence of an external finishing layer incorporated in the panels avoids having to carry out the final plastering.

The invention? susceptible to modifications and variations, all falling within the inventive concept expressed in the attached claims. In particular, the elements of the invention can be replaced by other technically equivalent elements.

Furthermore, the materials can be selected according to requirements, without however departing from the scope of the invention.

Furthermore, one or more elements of a specific embodiment of the invention technically compatible with another specific embodiment of the invention may be introduced into the latter in addition to or in substitution of elements of the latter.

Where the technical elements specified in the claims are followed by reference marks, these reference marks are included for the sole purpose of enhancing the understanding of the invention and, therefore, they do not imply any limitation to the claimed scope of protection.
