"INSULATING PANEL FOR RESIDENTIAL BUILDINGS ''

The invention relates to an insulating panel for residential buildings, particularly applicable on the roof of the same and made so as to carry out the. function of thermal iSOlament, waterproofing, ventilation and support structure. In the patent application for invention n. PN92A000055, filed on L?. * 7.1992 by the same Applicant,? described an insulating panel for residential buildings, applicable particularly on supporting structures of roofs of such buildings, together with other panels of the same type, and comprising a piece of almost shape? parallelepiped. or of other geometric shapes, made of heat-insulating material and preferably of expanded polystyrene or other suitable plastic material with an expanded cellular structure of the type known per se.

In the aforementioned panel, this piece? preferably made of form. flat, has a discontinuous upper surface with a plurality of of raised parts and of recessed parts with different shapes and arrangements, if this panel is applied on the roofs of the edifices, said parts being able to support a plurality of roof covering elements with different shapes and sizes, said piece being coated at least for its entire external surface. from matter, ie waterproofing against water. compatible with the material of the panel and applied at room temperature on said external surface, preferably from one or more? layers of bituminous emulsion., of the type used for road paving and from one or more layers, possibly overlying, of solid materials with fine grain, such as for example sandy materials preferably of the type or fine sand of the PQ, grits, etc. , designed to roughen and make said external surface aesthetically pleasing. The parts in relief and the recessed parts of the considered panel are defined by a plurality of d 'transverse rectilinear grooves, parallel and mutually equally spaced, by a plurality of of longitudinal rectilinear grooves parallel and mutually spaced and intersecting orthogonally the previous grooves, and by a plurality of grooves. of grooves grooved with opposite directions of inclination, made between said transversal and longitudinal rectilinear grooves.

Besides, the side profile of all the grooves? preferably wavy, with a series of depressions in the bottom areas of the longitudinal grooves, which are connected by means of convex inclined surfaces with a series of summits? provided in the bottom areas of the longitudinal grooves, finally, these Long itud inal grooves can be provided with a plurality of grooves, which extend horizontally for the entire width of each groove, in parallel and equidistant positions, in order to define a p lurality? d 1 recesses suitable for the insertion of the corresponding protrusions provided in the roofing elements (tiles, roof tiles, etc.), on which these and the roofing elements are also advantageously fixed by means of nails, screws and insertable elements, so as to prevent unwanted detachment and slippage of the covering elements from their position of application on the panels.

The panels thus made allow the support of covering elements almost? of all kinds, also insuring? an effective waterproofing action, thanks to the use of the b ituminous emulsion and the thin-grained soft materials for the coating of the external surface of the panels themselves, however in practice, yes? found that sometimes the insertion in the external surface of said panels of nails, screws and similar elements for the aforementioned purposes can? entail risks of damage and / or deformation of the constructive structure of the panels themselves, which normally? made of cellular material tending to flake and with reduced mechanical resistance, with consequent lower reliability functional of the panels themselves especially in the presence of roofs with strong inelinations in which the fixing of all the roofing elements to the relative panels must be absolutely safe and irremovable for any reason.

The present invention has the purpose of eliminating the drawbacks and limitations described above, by using an insulating panel for residential buildings capable of ensuring in a simple and rapid way a secure support and fastening of the roofing elements for application on roofs of any kind, and particular of roofs with strong inclinations, preventing any possibility? falls, detachments and unwanted damage to them.

This insulation panel? realized with the constructive characteristics substantially described with particular reference to the attached claims of the patent.

The invention will be pi? understandable from the following description, for non-limiting example purposes only and with reference to the attached drawings, in which:

Referring now to FIGS. 1-A, an insulating panel for residential buildings is shown according to the invention and obtained in a first embodiment thereof, which? practically identical to the panel described in the patent application for invention n. PN92A000055, filed on 1? .7? I99c by the same Applicant and it differs exclusively for the inventive characteristics that will be described below.

Also in this case, therefore, the insulating panel considered? essentially consisting of a flat piece? almost in shape? paraileiepjpeda, in the present case rectangular, but which of course can? be made also with other geometric shapes, said panel being made of heat-insulating material and preferably of expanded polystyrene or other suitable plastic material with expanded cellular structure, of limited specific weight and low cost, or also with possible further plastic materials of known type in s ?, possibly loaded with fillers known per se, which lend themselves to the heat-insulating materials function and which allow a compromised advantage between weight, phases and processing costs

In the present case of the panel in expanded polystyrene or in expanded plastic material of another kind ies. polyurethane), this panel has an upper main surface consisting of a plurality of parts in relief 7 and forming in their upper part a discontinuous flat surface B, and a plurality of parts in relief 7 of recessed parts 9, 10 for supporting different types of roof covering elements (tiles, bent tiles, etc.), if this insulating panel is applied to the roof of residential buildings as described in the aforementioned patent application.

For this purpose, this panel has a flat lower main surface 11 for adaptation to the support structures of the roofs of residential buildings, as well as for the adaptation to the roof support structures of residential buildings. has longitudinal 15 and transverse 13 surfaces which are also flat and lend themselves to juxtaposition with corresponding surfaces of identical insulating panels and the upper surface of the panel; it is also provided with a plurality of transverse rectilinear recesses 1A- of a given, identical width, extending over the entire width. of the panel and arranged parallel and mutually equidistant, as well as? of a plurality? of longitudinal rectilinear grooves 15 which orthogonally intersect the preceding grooves and extend throughout the length. of the cloth itself, parallel and reciprocally equidistant.

Furthermore, the upper surface of the panel? provided with a plurality? of longitudinal rectilinear grooves 16 made in an intermediate position and parallel to the previous grooves, as well as? of a plurality? of inclined recesses 17 and 18 symmetrical to each other, of the same determined length, and with opposite inclination directions, which are made in the areas of the upper surface of the panel defined between two longitudinal recesses 15 and two transverse recesses? 4. Finally, it is necessary to specify that the lateral profile of all the aforementioned recesses? corrugated with a series of depressions in the bottom areas 19 of the longitudinal grooves 15, which are connected by means of convex curved surfaces with a series of summits. provided in the bottom ions HO of the intermediate recesses L ??

The top surface of the panel? waterproofed with one or more? layers of a bituminous emulsion of the type commonly used to make road pavements, applied at room temperature on this external surface, together with sandy material or other suitable solid materials with fine grain, of the type described and claimed in the aforementioned patent application, and this panel can? also be provided with a plurality? of grooves 21 in the longitudinal grooves 15 and 1, extending horizontally for the entire width of each groove, positions parallel and equidistant to each other, in order to define a plurality of of grooves in which corresponding protrusions provided in the tiles or bent tiles can be inserted, with consequent locking in position of the same. According to the inventive characteristic of the present invention, the locking in position of the covering elements. of the roof and in particular of the tiles, which are devoid of edges? corner pieces which hook into corresponding transverse recesses 14 of the panel, edges which are instead provided in tiles of various kinds, is carried out by means of a plurality of elements. of raised parts HH provided on the upper surface of the insulating panel, in one piece with myself, preferably in correspondence with the intermediate recesses l ?, that is? in the positions in which the overturned cups are rested and fixed on said upper surface, said raised parts being provided with at least one respective internal insert made of suitable material with hardness and mechanical resistance greater than those of the material of the panels.

As shown in detail in fig. 4, each insert inter 23? preferably consisting of. high density p lastic material and with higher hardness and mechanical resistance than that of the plastic material of the Lio cream, for example polythyrene or other suitable high density plastic material, which is over-injected onto the plastic material. low density. of the insulating panel during the format of the same, so that the high density plastic material is result firmly embedded within the plastic material of said panel, furthermore, said internal insert 23 is provided with at least one cavity. 24, internally threaded less, penetrating for a determined depth? inside the respective insert, to allow the insertion of a corresponding threaded element or not, such as eg. threaded screw, bolt or similar, marked with the numerical reference 25 (fig. 3 *? which is previously inserted through a corresponding through hole of each tile or other covering element and subsequently through this cavity 24 to fix it firmly in such a position tile or roofing element, which is placed on the overturned panel, with its rounded convex surface, and on which the adjacent tiles, not overturned, are then placed on the two sides, thus preventing any danger of unwanted detachment, fall or seizure of all the bent tiles or roofing elements. from the upper surface of the present insulating panel. Naturally, the insert 23 can also be made in a manner and with material other than that described purely by way of example, without thereby leaving the scope protection of the present invention.

In this way, then, this insert can also be made of hard material of another kind such as e.g. metallic material, wood, ceramic or plastic filler materials of adequate hardness and mechanical strength, which can be incorporated with the panel material both during the forming of the latter and also separately Thanks to the presence of these raised parts 22 with inserts 23 in hard and mechanically resistant material, which can be joined together in a simple and rapid way with a few processing steps, thus it is possible to fix in position on the upper surface of the panel the tiles or other roof covering elements, by means of screws, nails, or similar fastening elements which interact with the hard and resistant material of these inserts, without these fastening elements coming into contact direct with the material the flaking and of reduced resistance of the breakdown itself, thus preventing with absolute certainty that undesired damages and / or deformations of the constructive structure of such panels are determined, and also ensuring? reliable and unmovable fixings of all roofing elements to the respective panels in the presence of any kind of roofs, and in particular in the presence of roofs even with strong inclinations, with the consequent elimination of any possibility? of falls, detachments and damage to the covering elements themselves Examining now figures 5 and 6, a possible embodiment of the panel according to the invention is shown, in which it is noted that in this case the panel has a slightly different construction from that previously described, in fact it? predisposed for the support and fixing on its upper surface exclusively of tiles and no more? of tiles of various kinds, as before. For this purpose, the panel? devoid of all the previously described grooves and? made with flat external surfaces, on which the upper surface? obtained a series of identical protruding elements 251, of the same thickness and spaced apart by an identical interval 252 in the direction of the width of the panel, said protruding elements 251 being shaped in the frame. of 26 degrees with corrugated profiles corresponding to the shape of the tiles, in order to allow the support of the tiles themselves, superimposed between them, on the upper edges of these profiles (as visible in the floor. h) and to also define? with the intervals 252 between the protruding elements 251 of the channels for the natural circulation of air, for the ventilation between each tile resting and fixed on the panel and the upper surface of the latter.

Examining now figs. 7 and S, an additional component 27 of the present insulating panel is schematically shown, which is applied on the roofs of residential buildings in combination with the panels considered, to allow support of the tiles, bent tiles and roof covering elements of different sizes and shapes, in the terminal and sloping area of the roofs themselves.

As can be seen particularly from these figures, the add-on 27? substantially constituted by a piece of heat-insulating material and preferably made of expanded polystyrene or other suitable plastic material. with expanded cellular structure, of high density, hardness and specific weight, preferably of the same component material as the internal inserts 23 of each insulating panel according to the invention, this piece being provided with two straight flat shanks 28 and 27 almost orthogonal to each other extending over the entire width of each respective insulating panel applied to the roof and suitably profiled above, in the ways and by the edges described below by way of example, of which the stem EB? intended to rest and to be fixed with its external flat surface on the roof, in its terminal and sloping area, and? able to get stuck in its extremity.

1free with the corresponding extremity? of respective insulating panels, for example by means of projection union? inta.g1io, so that a free space remains between the end edge? of said panels and the opposite, flat wall of the stem 29, thus locking said panels in position and preventing any unwanted sliding downwards.

THE fixing of this stem 2? of the additional component on the roof, in particular, is made by means of nails or similar fastening devices, which are first inserted through corresponding orthogonal through holes 30 of said stem and then tightly inserted into the roof itself. In turn, the remaining shank 29 of the additional component 27 protrudes beyond the outer surface. of each panel thus applied in position, to allow the support of the tiles, the bent tiles and the various roof covering elements used, in the manner described below, absolutely avoiding. safety any unwanted detachment or sliding downwards of the same.

Ne? I and fig. 9? LI three different construction versions of the add-on 27 specified above are now shown.

in which you notice the lower profile of the same? the same in all three versions and what? ? consisting of a flat bottom wall 31 for resting on the roof of residential buildings, in which various grooves 32 of different heights and shapes are obtained, extending throughout the thickness of the shank 29 and partly also in the shank 28 * for a depth of ? such as to communicate the free space defined on the end edge? of each insulating panel applied in position and the flat wall of the stem 29, so as to allow the circulation of an air flow ventilation from the outside through the interspace

between the upper outer surface of all the panels and the overlying covering elements, as can be seen particularly in fig. 12. The upper wall of these additional components, constituted by the upper edge of the stem 29, on the other hand,? shaped with different profiles to allow the support and fixing of tiles, bent tiles and roofing elements of different kinds. In particular, in fig. 9 you notice that the prof? Lo of the add-on 2? ? provided with a flat portion 33 which alternates with a semicircular portion 34, for "the support of corresponding tiles 35 of the" Portuguese "type, in Fig. 10 it can be seen that this additional component has a profile with a continuous rectilinear portion 36, for the support of corresponding tiles 37 of the "Marseillaise" type, while in the figures it is noted that this additional component has a profile with a curved recessed portion 38 which alternates with a protruding part 39, for the support of corresponding tiles 40 Furthermore, all the profiled portions of the upper wall of these additional components are suitably equipped with through grooves spaced apart and practiced for the entire thickness of the relative legs 29, respectively marked with the reference numerals 41, 42 and 43, to further ensure an effective circulation of the ventilation air in the space between the upper external surface of the iso Lat panels iti and the covering elements supported and fixed on them. Finally, examining fig. 12, the roof 44 of a residential building is schematically shown, on which the insulating panels according to the invention have been applied and fixed, as well as? the additional components 27. How is it clearly visible, then, since? the stem 29 of such additional components? raised with respect to the upper external surface of the panels, the tiles, bent tiles and other roofing elements that are arranged therein are placed on said stem 29 in a raised position and suitably fixed in position in the internal inserts 23 of the respective panels, so that they can no longer. slide downwards for the sp inta of the overlying roof covering elements.

The use of the additional components thus produced, in addition to ensuring the support and secure fixing of the roof covering elements, also allows an effective circulation of the ventilation air between the panels and the covering elements, which passing light? defined exclusively by the reduced dimensions of the through grooves 32 and 41, 42 or 43, which are chosen in such a way as to prevent any unwanted penetration of birds or insects of certain dimensions, a circumstance that allows to eliminate the flexible protections previously required for these purposes, simplifying thus considerably the construction of the assembly with consequent savings in materials and processing for the installation of such flexible protections.
