PANNELLO TERMOISOLANTE PER COPERTURE VENTILATE THERMAL INSULATION PANEL FOR VENTILATED ROOFS
DESCRIZIONE DESCRIPTION
II presente brevetto è attinente al settore degli elementi prefabbricati per l’edilizia ed in particolare concerne un nuovo pannello termoisolante composito, per la realizzazione di coperture coibentate e ventilate ad alta resistenza al fuoco. This patent relates to the sector of prefabricated building elements and in particular concerns a new composite thermal insulation panel, for the construction of insulated and ventilated roofs with high fire resistance.
Sono noti elementi modulari per la realizzazione di coperture comprendenti pannelli compositi di vario tipo. Modular elements are known for making roofs comprising composite panels of various types.
Sono noti pannelli o elementi di copertura compositi formati da una lamiera principale ondulata, nervata o grecata, sovrapposta ed accoppiata ad un pannello in materiale termo e fono isolante inferiore, la cui superficie superiore è corrispondentemente sagomata. Gli elementi di copertura compositi così costituiti presentano un adeguato isolamento termico e anche acustico, fungendo anche da barriera vapore. Composite roofing panels or elements formed by a corrugated, ribbed or corrugated main sheet, superimposed and coupled to a panel made of lower thermo and soundproof material, whose upper surface is correspondingly shaped, are known. The composite roofing elements thus constituted have adequate thermal and also acoustic insulation, also acting as a vapor barrier.
Detta lamiera principale e detto pannello isolante inferiore possono essere prodotti separatamente e tra loro successivamente uniti mediante colla disposta su alcuni punti di contatto. Said main sheet and said lower insulating panel can be produced separately and subsequently joined together by means of glue arranged on some contact points.
Sono anche noti elementi di copertura compositi, isolanti ed impermeabili, formati da una lamiera principale superiore, sagomata, grecata, ondulata o sostanzialmente piana ed uno strato inferiore in materiale espanso isolante direttamente sinterizzato su detta lamiera, detto materiale isolante essendo ad esempio polistirene espanso. Composite, insulating and waterproof covering elements are also known, formed by an upper main sheet, shaped, corrugated, corrugated or substantially flat and a lower layer of insulating foam material directly sintered on said sheet, said insulating material being for example expanded polystyrene.
La tecnica nota prevede che sulla lamiera superiore venga sinterizzato detto strato di materiale isolante. A tale scopo vengono utilizzati degli stampi, con relativi controstampi, in cui la lamiera che funge da rivestimento viene applicata al controstampo o comunque costituisce il coperchiocontrostampo. The known technique provides that said layer of insulating material is sintered on the upper sheet. For this purpose, molds are used, with relative counter-molds, in which the sheet metal that acts as a coating is applied to the counter-mold or in any case constitutes the counter-mold cover.
La lamiera ed il materiale isolante sono eterogenei e l’adesione del materiale isolante alla superficie della lamiera avviene in fase di espansione per incollaggio ove il materiale isolante aderisce ed si aggrappa nei punti dove la lamiera è bagnata da sostanze aggrappanti come i poliuretanici. The sheet and the insulating material are heterogeneous and the adhesion of the insulating material to the surface of the sheet occurs in the expansion phase by gluing where the insulating material adheres and clings to the points where the sheet is wetted by clinging substances such as polyurethane.
Tali sostanze aggrappanti aderiscono perfettamente alla lamiera e costituiscono una superficie di adesione per il materiale isolante in sinterizzazione. These adhering substances adhere perfectly to the sheet and form an adhesion surface for the sintering insulating material.
Dette lamiere sono grecate, ondulate o altrimenti piegate per costituire un irrigidimento del pannello ed una canalizzazione superiore di scorrimento delle acque meteoriche. Said sheets are corrugated, corrugated or otherwise bent to form a stiffening of the panel and an upper channeling for the flow of rainwater.
Detta lamiera metallica superiore può anche avere forma riproducente la sagoma dei coppi in laterizio, unita, per tutta la superficie ed in completa aderenza, con uno strato inferiore di polistirene espanso isolante. Said upper metal sheet can also have a shape reproducing the shape of the brick tiles, joined, for the whole surface and in complete adherence, with a lower layer of insulating expanded polystyrene.
Sono anche noti pannelli metallici "sandwich", ossia formati da una coppia di lamiere metalliche affacciate, tra le quali vengono generalmente iniettate delle resine che, espandendosi, saturano tutto il volume Ubero e, grazie alla loro composizione chimica, solidificano aggrappandosi alle pareti interne delle lamiere formando con esse un unico elemento solidale e monolitico. In alternativa alle resine espandibili si possono utilizzare dei pannelli isolanti già predisposti, come lastre di polistirolo espanso o estruso, da incollare fra le due lamiere metalliche che possono avere le superfici piane o grecate, con conformazione diritte o curve. "Sandwich" metal panels are also known, i.e. formed by a pair of facing metal sheets, between which resins are generally injected which, expanding, saturate the entire free volume and, thanks to their chemical composition, solidify by clinging to the internal walls of the sheets forming with them a single integral and monolithic element. As an alternative to expandable resins, pre-prepared insulating panels can be used, such as expanded or extruded polystyrene sheets, to be glued between the two metal sheets which may have flat or corrugated surfaces, with straight or curved conformation.
Tali pannelli compositi hanno un buon isolamento termico però presentano una bassa resistenza al fuoco ed una bassa fonoassorbenza per la caratteristica specifica delle resine espanse e per la conformità stessa dei pannelli sandwich. These composite panels have good thermal insulation but have low fire resistance and low sound absorption due to the specific characteristic of the expanded resins and the conformity of the sandwich panels.
Sono noti inoltre pannelli metallici sandwich accoppiati con fibre minerali orientate verso le rispettive pareti metalhche di cui una, quella rivolta verso Tintemo dell’edificio, risulta essere forata. Questo pannello ha una buona resistenza al fuoco e contemporaneamente ha un buon abbattimento acustico; per contro ha un elevato costo, non risolve il problema dei fumi e dello smaltimento del calore in caso di incendio e può rilasciare nell’ ambiente, attraverso la foratura della lamiera, pericolose polveri o parti di fibre minerali che compongono l’anima del pannello inoltre l’isolamento termico è minore se confrontato con quello dei materiali isolanti espansi a parità di spessori. Sandwich metal panels coupled with mineral fibers oriented towards the respective metal walls are also known, one of which, the one facing towards the building's color, is perforated. This panel has good fire resistance and at the same time has good noise reduction; on the other hand, it has a high cost, does not solve the problem of fumes and heat dissipation in the event of a fire and can release into the environment, through the drilling of the sheet metal, dangerous dust or parts of mineral fibers that make up the core of the panel. thermal insulation is lower if compared with that of expanded insulating materials with the same thickness.
Altra tecnica nota comprende pannelli di copertura in lamiera nervata con incollato inferiormente un pannello in materiale isolante pieno con bordo inferiore completamente piano. Another known technique comprises covering panels in ribbed sheet metal with a panel of solid insulating material glued at the bottom with a completely flat lower edge.
Sono noti gli impieghi di lamiere nervate non isolate per la realizzazione di coperture di edifici residenziali ed edifici industriali in genere. Tali lamiere superiori non isolate sono soggette ai fenomeni di condensa dovuta alla bassa temperatura esterna ed al valore dell’umidità dell’aria, che a contatto con la fredda superficie inferiore delle lamiere nervate porta alla formazione di gocce. Dette gocce staccandosi cadono sul sottostante controsoffitto rovinandolo esteticamente, e/o sul sottostante strato isolante inumidendolo, con conseguente aumento del carico, con rischi di distacchi e piccoli crolli. Sono note anche le lamiere nervate di copertura dotate di uno strato o telo in feltro, incollato inferiormente con funzione anticondensa, ma privo di ogni capacità di coibenza termica e di fonoassorbenza. The uses of non-insulated ribbed sheets for the construction of roofing of residential buildings and industrial buildings in general are known. These non-insulated upper sheets are subject to condensation due to the low external temperature and the humidity of the air, which in contact with the cold lower surface of the ribbed sheets leads to the formation of drops. When these drops come off, they fall on the underlying false ceiling, ruining it aesthetically, and / or on the underlying insulating layer, moistening it, with a consequent increase in the load, with the risk of detachments and small collapses. Also known are the ribbed roofing sheets equipped with a layer or sheet of felt, glued at the bottom with an anti-condensation function, but without any capacity for thermal insulation and sound absorption.
Oggetto del presente brevetto è un nuovo tipo di pannello termoisolante composito, per la realizzazione di coperture ventilate, ad elevata resistenza al fuoco, termoisolanti e fonoassorbenti. The subject of this patent is a new type of composite heat-insulating panel, for the construction of ventilated, high-fire-resistant, heat-insulating and sound-absorbing roofs.
Compito principale del presente trovato è quello di realizzare una copertura avente elevata resistenza al fuoco. La nuova copertura è pertanto particolarmente adatta anche all'installazione di pannelli fotovoltaici o solari in genere. The aim of the present invention is to provide a covering having a high resistance to fire. The new roof is therefore particularly suitable for the installation of photovoltaic or solar panels in general.
Il nuovo pannello comprende due lamiere con intercapedine d'aria, risultando quindi conforme alla guida per l'installazione di impianti fotovoltaici contenuti nel DPR 1.8.2011 n. 151 sostituendo la precedente Nota Prot n. 5158 del 26/03/2010. The new panel includes two sheets with an air gap, thus complying with the guide for the installation of photovoltaic systems contained in Presidential Decree 1.8.2011 n. 151 replacing the previous Note Prot no. 5158 of 03/26/2010.
Altro scopo del presente trovato è reahzzare una copertura ventilata. Another object of the present invention is to provide a ventilated cover.
Altro scopo del presente trovato è realizzare una copertura termo isolante e fonoassorbente. Another object of the present invention is to provide a thermo-insulating and sound-absorbing cover.
Altro scopo del presente trovato è quella di realizzare una copertura traspirante, con lamiere microforate. Another object of the present invention is to provide a transpiring cover with micro-perforated sheets.
Questi ed altri scopi, diretti e complementari, sono raggiunti dal nuovo pannello termisolante composito, per la realizzazione di coperture ventilate, ad elevata resistenza al fuoco, termoisolanti e fonoassorbenti. These and other direct and complementary purposes are achieved by the new composite heat-insulating panel, for the construction of ventilated roofs with high fire resistance, heat-insulating and sound-absorbing roofs.
Il nuovo pannello termoisolante per coperture ventilate comprende almeno una lamiera principale, preferibilmente grecata o nervata, e almeno una lastra o strato isolante in materiale espanso o in fibre minerali vincolato all'intradosso di detta lamiera principale, ad esempio sinterizzato su essa o incollato, e dove almeno un'ulteriore lamiera di copertura, anch'essa preferibilmente nervata o grecata, è vincolata superiormente a detta lamiera principale, individuando una pluralità di intercapedini o canalizzazioni tra le nervature o greche di detta lamiera principale e di detta lamiera di copertura. Dette nervature o greche di detta lamiera principale e di detta lamiera di copertura possono avere forma speculare o disposizione diversa, tale che sovrapponendo detta lamiera di copertura a detta lamiera principale, siano individuate dette intercapedini o canalizzazioni per l'aria. The new thermal insulation panel for ventilated roofs comprises at least one main sheet, preferably corrugated or ribbed, and at least one sheet or insulating layer made of expanded material or mineral fibers bonded to the intrados of said main sheet, for example sintered on it or glued, and where at least one further cover plate, also preferably ribbed or ribbed, is constrained above said main plate, identifying a plurality of gaps or channels between the ribs or ribs of said main plate and said cover plate. Said ribs or frets of said main plate and said cover plate can have a specular shape or different arrangement, such that by superimposing said cover plate on said main plate, said air spaces or ducts are identified.
Detta lamiera principale e detta lamiera di copertura sono inoltre conformate in modo che i rispettivi bordi laterali e uno o più punti intermedi possano essere tra loro uniti, ad esempio per saldatura. Said main plate and said covering plate are furthermore shaped so that the respective lateral edges and one or more intermediate points can be joined together, for example by welding.
Dette lamiere principale e di copertura, in alternativa o in combinazione alla saldatura, possono essere tra loro unite meccanicamente mediante graffatura e/o mediante rivettatura e/o altri mezzi di fissaggio. In alternativa o in combinazione, è possibile prevedere che dette lamiere principale e di copertura siano tra loro unite per deformazione puntuale in corrispondenza di detti punti di contatto e/o di detti bordi laterali. Said main and cover plates, alternatively or in combination with welding, can be mechanically joined together by stapling and / or by riveting and / or other fastening means. Alternatively or in combination, it is possible to provide that said main and cover plates are joined together by punctual deformation at said contact points and / or said lateral edges.
Detto pannello termoisolante per coperture ventilate comprende anche preferibilmente almeno una lamiera inferiore di finitura, ad esempio preferibilmente liscia oppure nervata, e dove detta lastra o strato isolante è interposto tra dette lamiere principale e inferiore. Said thermal insulating panel for ventilated roofs also preferably comprises at least one lower finishing sheet, for example preferably smooth or ribbed, and where said insulating plate or layer is interposed between said main and lower sheets.
Dette lamiere inferiore e/o principale possono essere microforate. Said lower and / or main sheets can be micro-perforated.
Detto strato intermedio in materiale isolante può essere realizzato in polistirene, materiali poliuretanici o fibre minerali o altro materiale adeguato con caratteristiche di isolamento termico e acustico, in funzione del REI che si vuole ottenere. Said intermediate layer in insulating material can be made of polystyrene, polyurethane materials or mineral fibers or other suitable material with thermal and acoustic insulation characteristics, depending on the REI to be obtained.
Le caratteristiche del nuovo pannello termoisolante per coperture ventilate saranno meglio chiarite dalla seguente descrizione con riferimento alla tavola di disegno, allegata a titolo di esempio non limitativo, dove in figura I viene presentata in sezione una pratica realizzazione del trovato. The characteristics of the new thermal insulating panel for ventilated roofs will be better clarified by the following description with reference to the drawing table, attached by way of non-limiting example, where in figure I a practical embodiment of the invention is presented in section.
Si tratta di un pannello termoisolante (1) per coperture ventilate comprendente una lamiera principale (2) con una pluralità di greche o nervature (21) e preferibilmente anche una lamiera inferiore (3) di finitura, ad esempio liscia o anch'essa nervata. It is a thermal insulating panel (1) for ventilated roofs comprising a main sheet (2) with a plurality of ribs or ribs (21) and preferably also a lower finishing sheet (3), for example smooth or also ribbed.
Tra dette lamiere principale (2) e inferiore (3) è interposto e vincolato almeno una lastra o strato isolante (4) in materiale espanso o fibre minerali, vincolato all'intradosso o facce interne (26, 31) di dette lamiere principale (2) e inferiore (3). Between said main (2) and lower (3) sheets there is interposed and constrained at least one sheet or insulating layer (4) made of expanded material or mineral fibers, constrained to the intrados or internal faces (26, 31) of said main sheets (2 ) and lower (3).
Detto strato (4) isolante è ad esempio direttamente sinterizzato o schiumato su dette lamiere (2, 3) oppure incollato. Said insulating layer (4) is for example directly sintered or foamed on said sheets (2, 3) or glued.
Detto strato (4) isolante ha superficie superiore (43) di preferenza sostanzialmente piana oppure conformata in modo corrispondente alla forma di detta lamiera principale (2). Said insulating layer (4) has an upper surface (43) which is preferably substantially flat or shaped in a manner corresponding to the shape of said main sheet (2).
II nuovo pannello termoisolamte (1) comprende anche almeno un'ulteriore lamiera di copertura (5), anch'essa nervata o grecata, ossia comprendente una pluralità di greche o nervature (51), e dove detta lamiera di copertura (5) è superiormente affacciata a detta lamiera principale (2) e ad essa vincolata. Dette nervature o greche (21, 51) di detta lamiera principale (2) e di detta lamiera di copertura (5) hanno forma e disposizione non corrispondente tale che sovrapponendo detta lamiera di copertura (5) a detta lamiera principale (2) siano individuate una pluralità di intercapedini o canalizzazioni (6) per l'aria tra le lamiere (2, 5) stesse. The new heat-insulating panel (1) also comprises at least one further covering sheet (5), also ribbed or ribbed, i.e. comprising a plurality of ribs or ribs (51), and where said covering sheet (5) is at the top facing said main sheet (2) and constrained thereto. Said ribs or frets (21, 51) of said main sheet (2) and of said cover sheet (5) have a shape and arrangement that does not correspond such that by superimposing said covering sheet (5) to said main sheet (2) they are identified a plurality of cavities or channels (6) for the air between the sheets (2, 5) themselves.
Nella soluzione attuativa rappresentata in figura 1, dette nervature (51) della lamiera di copertura (5) sono sostanzialmente uguali ma disposte sfalsate e/o speculari rispetto alle nervature (21) di detta lamiera principale (2) e dove tra nervature (21, 51) successive sono individuate dette intercapedini o canalizzazioni (6). In the embodiment represented in Figure 1, said ribs (51) of the cover plate (5) are substantially the same but arranged offset and / or specular with respect to the ribs (21) of said main plate (2) and where between ribs (21, 51) subsequent ones are identified as cavities or channels (6).
Dette nervature (21, 51) di ciascuna lamiera principale (2) o di copertura (5) hanno ad esempio forma quadra o trapezia ossia comprendono una parte piana (22, 52) atta a risultare contrapposta e a contatto ad una corrispondente parte piana (53, 23) della lamiera (5, 2) affacciata. Said ribs (21, 51) of each main sheet (2) or cover (5) have, for example, a square or trapezoidal shape, i.e. they comprise a flat part (22, 52) capable of being opposed and in contact with a corresponding flat part (53 , 23) of the facing sheet metal (5, 2).
Detta lamiera principale (2) e detta lamiera di copertura (5) sono tra loro vincolate almeno in corrispondenza di detta parti piane (22, 52, 23, 53) a contatto, aumentando di fatto la portata e la pedonalità superiore, fatto questo rilevante considerato che, data la sua struttura fibrosa, lo strato isolante (4) non ha resistenza alla compressione e quindi ai carichi. Said main sheet (2) and said cover sheet (5) are constrained to each other at least in correspondence with said flat parts (22, 52, 23, 53) in contact, effectively increasing the range and the upper pedestrian traffic, which is a significant fact considering that, given its fibrous structure, the insulating layer (4) has no resistance to compression and therefore to loads.
Detta lamiera principale (2) e detta lamiera di copertura (5) comprendono bordi laterali (24, 54, 25, 55) sagomati, ad esempio ripiegati, per la reciproca connessione. Said main plate (2) and said covering plate (5) comprise shaped side edges (24, 54, 25, 55), for example folded, for mutual connection.
Dette lamiere principale (2) e di copertura (5) sono in particolare tra loro uniti lungo dette parti piane (22, 52, 23, 53) di contatto e detti bordi (24, 54, 25, 55) ad esempio per saldatura e/o tramite graffatura e/o mediante rivettatura e/o altri mezzi di fissaggio e/o tra loro unite per deformazione puntuale. Said main (2) and cover (5) sheets are in particular joined together along said flat contact parts (22, 52, 23, 53) and said edges (24, 54, 25, 55) for example by welding and / or by stapling and / or by riveting and / or other fastening means and / or joined together by punctual deformation.
Il nuovo pannello termoisolante (1) ha larghezza modulare e comprende lati (11, 12) conformati per l'accoppiamento con pannelli (1) adiacenti. In particolare, detti bordi laterali (24, 25, 25, 55) di dette lamiere principale (2) e di copertura (5) sono ripiegati per laccoppiamento con il corrispondente bordo laterale del pannello (1) adiacente. The new thermal insulation panel (1) has a modular width and includes sides (11, 12) shaped for coupling with adjacent panels (1).
