DESCRIZIONEDESCRIPTION La presente invenzione ha per oggetto un pannello modulare, per sottocoperture di edifici civili o industriali.The present invention relates to a modular panel for under-roofing of civil or industrial buildings. Pannelli per sottocoperture, da interporsi cioè tra listelli in legno e un tetto in tegole, sono già noti e sono normalmente a forma di lastre piane, ad esempio in polistirolo estruso, lana di vetro o di roccia, sughero espanso e simili.Panels for under-roofs, ie to be placed between wooden strips and a tiled roof, are already known and are normally in the form of flat plates, for example made of extruded polystyrene, glass or rock wool, expanded cork and the like. Con tali pannelli noti non si riesce a raggiungere un buon compromesso tra peso del pannello, resistenza meccanica, isolamento termico, impermeabilità, etc.With these known panels it is not possible to reach a good compromise between panel weight, mechanical strength, thermal insulation, impermeability, etc. Inoltre, tali lastre piane non si prestano in modo soddisfacente a sostenere una copertura di tegole curve, comunemente chiamate coppi.Furthermore, these flat slabs are not suitable for supporting a covering of curved tiles, commonly called bent tiles. Esistono, invero, anche pannelli ondulati particolarmente adatti per coperture in coppi, quali ad esempio le lastre ondulate in cemento amianto, note col nome commerciale «Eternit».Indeed, there are also corrugated panels particularly suitable for roofing tiles, such as for example the corrugated asbestos cement sheets, known by the trade name «Eternit». Tali lastre sono, però, notevolmente pesanti e non hanno buone caratteristiche di isolamento.However, these slabs are considerably heavy and do not have good insulation characteristics. Inoltre, in fase di installazione, le lastre ondulate note devono essere parzialmente sovrapposte per garantire una continuità della sottocopertura, ciò che comporta uno spreco di materiale e una non uniformità delle tegole in corrispondenza delle zone di sovrapposizione delle lastre ondulate.Furthermore, during installation, the known corrugated sheets must be partially overlapped to ensure continuity of the under-roof, which entails a waste of material and non-uniformity of the tiles in correspondence with the overlapping areas of the corrugated sheets. Scopo dell'invenzione è quello di eliminare gli inconvenienti illustrati, fornendo un pannello modulare per sottocoperture, di peso molto contenuto, con elevata resistenza meccanica, con ottime caratteristiche di isolamento e completamente impermeabile.The object of the invention is to eliminate the drawbacks illustrated, providing a modular panel for underroofs, which is very light in weight, has high mechanical strength, excellent insulation characteristics and is completely waterproof. Tale scopo viene raggiunto, in accordo all'invenzione, con questo pannello costituito da poliuretano caricato con fibre di vetro.This object is achieved, according to the invention, with this panel made of polyurethane reinforced with glass fibres. In vantaggio principale del presente pannello è un risparmio di materiale.The main advantage of the present panel is a saving of material. Il presente pannello può essere vantaggiosamente a cellule chiuse e risulta autoportante, per cui si può aumentare la distanza tra i listelli sui quali esso viene poggiato, semplificandone l'installazione e ottenendo allo stesso tempo un risparmio di materiale.The present panel can advantageously have closed cells and is self-supporting, so that the distance between the strips on which it rests can be increased, simplifying its installation and at the same time obtaining a saving of material. Secondo una forma preferita di realizzazione, il presente pannello può vantaggiosamente essere di tipo ondulato, particolarmente adatto per coperture in tegole curve o coppi, e presenta i bordi laterali scanalati da bande opposte, in modo che nella composizione della sottocopertura i bordi scanalati di pannelli adiacenti si sovrappongono senza determinare un au-s mento di spessore del pannello.According to a preferred embodiment, the present panel can advantageously be of the corrugated type, particularly suitable for roofs made of curved tiles or pantiles, and has the side edges grooved on opposite sides, so that in the composition of the under roof the grooved edges of adjacent panels overlap without causing an increase in panel thickness. In tal modo si ha il suddetto risparmio di materiale, in quanto non si ha accavallamento tra pannelli adiacenti, e allo stesso tempo si ottiene una superficie di sottotetto perfettamente ondulata, che consente una posa uniforme del tetto a tegole io curve.In this way there is the aforesaid saving of material, since there is no overlap between adjacent panels, and at the same time a perfectly corrugated under-roof surface is obtained, which allows a uniform laying of the roof with curved or tiled tiles. Ulteriori vantaggi del presente pannello, risulteranno più chiari dalla descrizione dettagliata che segue, riferita ad una sua forma puramente esemplificativa e quindi non limitativa di realizzazione, illustrata nei disegni annessi in cui:Further advantages of the present panel will become clearer from the following detailed description, referring to a purely exemplifying and therefore non-limiting embodiment thereof, illustrated in the attached drawings in which: 15 la fig. 1 è una vista assonometrica mostrante l'affiancamen-to di due pannelli ondulati secondo l'invenzione;15 fig. 1 is an axonometric view showing the side by side of two corrugated panels according to the invention; la fig. 2 è una vista parziale in sezione, presa secondo la linea II-II di Fig. 1, mostrante, in scala maggiore, un dettaglio dell'affiancamento di due pannelli.the fig. 2 is a partial sectional view, taken along the line II-II of Fig. 1, showing, on a larger scale, a detail of the juxtaposition of two panels. 20 Con riferimento a tali figure, con 1 è stato indicato un pannello secondo l'invenzione che, nella realizzazione preferita raffigurata, è di tipo ondulato ed è quindi particolarmente adatto a coperture con tegole curve o coppi, o per coperture con lastre ondulate.20 With reference to these figures, numeral 1 indicates a panel according to the invention which, in the preferred embodiment shown, is of the corrugated type and is therefore particularly suitable for roofs with curved tiles or pantiles, or for roofs with corrugated sheets. 25 II pannello 1 ha dimensioni modulari e viene poggiato, ad esempio, su listelli in legno ai quali può essere fissato per chiodatura. I listelli in legno possono far parte di un telaio portante in legno, o essere a loro volta fissati ad un solaio in cemento armato.25 Panel 1 has modular dimensions and is placed, for example, on wooden slats to which it can be fixed by nailing. The wooden slats can be part of a wooden load-bearing frame, or in turn be fixed to a reinforced concrete floor. 30 Sui bordi laterali di ciascun pannello 1 sono previste rispettive scanalature 2 e 3, estendentesi per tutta la lunghezza del pannello e aperte rispettivamente verso il basso e verso l'alto.30 On the lateral edges of each panel 1, respective grooves 2 and 3 are provided, extending along the entire length of the panel and opening downwards and upwards, respectively. Tali scanalature 2 e 3 vengono ricavate mediante asportazione di materiale dal pannello, determinando sui bordi laterali 35 dello stesso dei tratti sporgenti, rispettivamente 4 e 5, che vengono a sovrapporsi nell'affiancamento di due pannelli, come chiaramente visibile dalle figure, senza determinare un aumento di spessore dei pannelli nella zona di sovrapposizione, ottenendo così una superficie uniformemente ondulata. 40 II prolungamento in lunghezza dei pannelli avviene semplicemente attestando i bordi ondulati degli stessi gli uni contro gli altri. Ciò comporta un risparmio di materiale, in quanto non c'è accavallamento tra pannelli contigui, e consente una agevole posa della copertura, che risulta perfettamente uniforme. 45 II pannello 1, in accordo all'invenzione, è ricavato per stampaggio di poliuretano caricato con fibre di vetro.These grooves 2 and 3 are obtained by removing material from the panel, forming protruding portions 4 and 5 on the side edges 35 thereof, which overlap when two panels are side by side, as clearly visible from the figures, without causing a increase in thickness of the panels in the overlapping area, thus obtaining a uniformly corrugated surface. 40 The lengthening of the panels occurs simply by abutting their wavy edges against each other. This results in material savings, as there is no overlap between contiguous panels, and allows easy laying of the roof, which is perfectly uniform. 45 The panel 1, according to the invention, is obtained by molding polyurethane loaded with glass fibres. Sorprendentemente si è osservato che un pannello così ottenuto presenta eccellenti caratteristiche, non ottenibili con i materiali finora impiegati per gli stessi scopi.Surprisingly, it has been observed that a panel thus obtained has excellent characteristics which cannot be obtained with the materials used up to now for the same purposes. so Esso è infatti completamente impermeabile all'acqua, in quanto è a cellule chiuse; presenta elevate proprietà di isolamento termico; risulta di peso molto contenuto ed è dotato di notevole resistenza meccanica alla compressione.so It is in fact completely impermeable to water, as it has closed cells; has high thermal insulation properties; it is very light in weight and has considerable mechanical resistance to compression. Ad esempio un pannello ondulato di dimensioni utili 183 x 55 89 cm e spessore di 1,3 cm, ha un peso di circa 3 kg e presenta una resistenza alla compressione di circa 3 kg/cmq.For example, a corrugated panel with useful dimensions 183 x 55 89 cm and a thickness of 1.3 cm has a weight of about 3 kg and has a compressive strength of about 3 kg/cm2. Naturalmente al pannello modulare per sottocoperture, oggetto dell'invenzione, precedentemente descritto ed illustrato con riferimento ad una sua forma puramente esemplificativa di 60 realizzazione, possono essere apportate numerose modifiche di dettaglio, senza per questo uscire dall'ambito dell'invenzione stessa.Of course, numerous detailed modifications can be made to the modular panel for under-roofs, object of the invention, previously described and illustrated with reference to a purely exemplifying embodiment thereof, without thereby departing from the scope of the invention itself. vv 1 foglio disegni1 drawing sheet
