Description

Panneau isolant autoporteur pour toiture Self-supporting roof insulation panel
La présente invention concerne le domaine du bâtiment, en particulier les éléments de construction et notamment les panneaux isolants de toiture, et a pour objet un tel panneau isolant autoporteur pour toiture.The present invention relates to the building sector, in particular construction elements and in particular roof insulation panels, and relates to such a self-supporting insulation panel for roofs.
Actuellement, les panneaux isolants de toiture sont généralement sous forme de panneaux sandwichs essentiellement constitués par une couche isolante interne, le plus souvent en matière synthétique expansée, cette couche étant entourée par des plaques externes rigides. De tels panneaux peuvent être fixés directement sur des chevrons de charpente par vissage ou par clouage et sont munis sur leur face externe d'un double lattage permettant la pose de tuiles avec réalisation d'un espace de circulation d'air sous ces dernières.Currently, insulating roofing panels are generally in the form of sandwich panels essentially constituted by an internal insulating layer, most often made of expanded synthetic material, this layer being surrounded by rigid external plates. Such panels can be fixed directly to roof rafters by screwing or nailing and are provided on their external face with a double lath allowing the laying of tiles with the creation of an air circulation space under the latter.
Ces panneaux présentent une rigidité transversale et longitudinale correcte pour leur manutention, mais ne sont pas autoporteurs, du fait qu'ils ne peuvent pas être posés directement sur les poutres porteuses d'une charpente sans interposition de chevrons garantissant la rigidité longitudinale sous la charge de la couverture.These panels have a correct transverse and longitudinal rigidity for their handling, but are not self-supporting, because they cannot be placed directly on the supporting beams of a frame without interposition of rafters guaranteeing the longitudinal rigidity under the load of the cover.
En outre, du fait qu'ils présentent une surface externe parfaitement plane, un double lattage est obligatoire pour permettre une circulation d'air sous la couverture, afin d'en assurer un bon état, ce qui entraîne que le prix de revient d'une toiture ainsi réalisée est relativement élevé, tant en raison des matériaux mis en oeuvre, que de la main d'oeuvre nécessaire.In addition, because they have a perfectly flat external surface, double battening is compulsory to allow air circulation under the cover, in order to ensure a good condition, which results in the cost of a roof thus produced is relatively high, both because of the materials used, and the labor required.
On connaît également, par FR-A-2 715 955 un panneau de ce type constitué par un corps en un matériau isolant rigide qui est relié, au moyen d'inserts, respectivement, à un élément porteur et à un élément de revêtement. Un tel panneau n'est pas porteur en lui-même, mais uniquement du fait qu'il est monté sur un élément porteur plan. En outre, il ne prévoit aucun moyen de montage de tuiles ou d'autres éléments de couverture, ce avec possibilité simultanée d'une circulation d'air sous la couverture.Also known from FR-A-2 715 955 is a panel of this type constituted by a body of rigid insulating material which is connected, by means of inserts, respectively, to a support element and to a coating element. Such a panel is not load-bearing in itself, but only because it is mounted on a flat load-bearing element. In addition, it does not provide any means of mounting tiles or other covering elements, with the simultaneous possibility of air circulation under the covering.
La présente invention a pour but de pallier ces inconvénients en proposant un panneau isolant autoporteur pour toiture permettant de réaliser une couverture de toiture à un coût réduit par rapport aux moyens existant actuellement, tout en assurant une meilleure capacité d'absorption de charge.The object of the present invention is to overcome these drawbacks by proposing a self-supporting insulating panel for a roof making it possible to produce a roof covering at a reduced cost compared to the means currently existing, while ensuring better load absorption capacity.
A cet effet, le panneau isolant pour toiture, qui est essentiellement constitué par un bloc rigide en matière isolante, est caractérisé en ce" qu'il est autoporteur et en ce qu'il comporte au moins un profilé de reprise des efforts, inséré dans la matière isolante inséré dans la matière isolante par surmoulage au moyen du matériau constitutif dudit bloc, dans le sens longitudinal du panneau.To this end, the insulating panel for roofing, which is essentially constituted by a rigid block of insulating material, is characterized in that " it is self-supporting and in that it comprises at least one profile for taking up forces, inserted into the insulating material inserted into the insulating material by overmolding by means of the material constituting said block, in the longitudinal direction of the panel.
L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels : la figure 1 est une vue en coupe transversale d'un panneau conforme à l'invention ; la figure 2 est une vue en perspective du panneau ; la figure 3 est une vue en coupe transversale, à plus grande échelle, d'une fente d'insertion d'un liteau de réception de tuiles ou analogues ; la figure 4 est une vue partielle en perspective représentant la fixation d'une extrémité du panneau sur une panne ; la figure 5 est une vue partielle en perspective représentant l'aboutement de deux panneaux ; la figure 6 est une vue partielle en coupe longitudinale d'un panneau en position de service, et la figure 7 est une vue partielle en perspective, à plus grande échelle, d'un liteau de réception de tuiles ou analogues.The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which: FIG. 1 is a cross-sectional view of a panel according to the invention; Figure 2 is a perspective view of the panel; FIG. 3 is a cross-sectional view, on a larger scale, of an insertion slot for a tile-receiving batten or the like; Figure 4 is a partial perspective view showing the attachment of one end of the panel on a purlin; Figure 5 is a partial perspective view showing the abutment of two panels; FIG. 6 is a partial view in longitudinal section of a panel in the service position, and FIG. 7 is a partial perspective view, on a larger scale, of a tile for receiving tiles or the like.
La figure 1 des dessins annexés représente un panneau isolant pour toiture, qui est essentiellement constitué par un bloc rigide 1 en matière isolante. Comme le montrent les figures 4 à 6, des panneaux de ce types sont destinés à être montés sur des pannes de toiture 2 ou des supports analogues.Figure 1 of the accompanying drawings shows an insulating panel for roofing, which is essentially constituted by a rigid block 1 of insulating material. As shown in Figures 4 to 6, panels of this type are intended to be mounted on roof purlins 2 or similar supports.
Conformément à l'invention, le bloc rigide 1 est autoporteur et comporte au moins un profilé 3 de reprise des efforts, inséré dans la matière isolante inséré dans la matière isolante par surmoulage au moyen du matériau constitutif dudit bloc, dans le sens longitudinal du panneau. Un tel surmoulage est réalisé par disposition du ou des profilés 3 dans un moule, puis injection du matériau isolant, de préférence sous forme d'une mousse synthétique en expansion. De préférence, chaque bloc rigide 1 constitutif d'un panneau est pourvu de deux profilés 3 s'étendant parallèlement entre-eux et disposés symétriquement par rapport à l'axe longitudinal du panneau.According to the invention, the rigid block 1 is self-supporting and comprises at least one profile 3 for taking up the forces, inserted into the insulating material inserted into the insulating material by overmolding by means of the material of said block, in the longitudinal direction of the panel. . Such overmolding is carried out by placing the section or sections 3 in a mold, then injecting the insulating material, preferably in the form of an expanding synthetic foam. Preferably, each rigid block 1 constituting a panel is provided with two sections 3 extending parallel to each other and arranged symmetrically with respect to the longitudinal axis of the panel.
Les profilés 3 sont avantageusement constitués en un matériau à haute résistance mécanique, en particulier à la flexion, à savoir, notamment en tôle d'acier ou en un composite synthétique armé. Ainsi, après surmoulage des profilésThe profiles 3 are advantageously made of a material with high mechanical resistance, in particular to bending, namely, in particular sheet steel or a reinforced synthetic composite. Thus, after overmolding of the profiles
3, le panneau obtenu présente une bonne rigidité longitudinale, là rigidité transversale étant assurée grâce à la faible largeur des panneaux comparativement à leur longueur.3, the panel obtained has good longitudinal rigidity, there rigidity transverse being ensured thanks to the small width of the panels compared to their length.
Conformément à une autre caractéristique de l'invention, les profilés 3 présentent, de préférence, une section droite en Z (figures 1, 2 4 et 5). Une telle section permet, d'une part, de garantir une importante surface de contact entre les profilés 3 et le matériau constitutif du bloc rigide 1 et, d'autre part, d'utiliser les ailes parallèles du Z formant le profilé pour coopérer avec des moyens de fixation sur les pannes 2 ou de fixation d'autres éléments sur lesdits profilés 3 et donc sur le panneau. A cet effet, le bloc rigide 1 peut avantageusement être muni, en fonction des besoins, au droit de chaque aile inférieure des profilés 3, de trous de passage 4 s'étendant de la face supérieure du bloc 1 jusqu'à ladite aile (figures 2 et 4). Ces trous 4 sont effectués sur chantier à un entraxe correspondant à l'entraxe entre deux pannes. La fixation de panneaux conforme à l'invention sur des pannes peut donc être réalisée facilement par mise en oeuvre de vis auto-perçantes 5 et auto-taraudeuses simplement insérées dans les trous 4 et actionnées au moyen d'une visseuse ou analogue.According to another characteristic of the invention, the profiles 3 preferably have a cross section in Z (Figures 1, 2 4 and 5). Such a section makes it possible, on the one hand, to guarantee a large contact surface between the profiles 3 and the material constituting the rigid block 1 and, on the other hand, to use the parallel wings of the Z forming the profile to cooperate with fixing means on the purlins 2 or fixing of other elements on said sections 3 and therefore on the panel. To this end, the rigid block 1 can advantageously be provided, as required, at the level of each lower wing of the profiles 3, with through holes 4 extending from the upper face of the block 1 to said wing (FIGS. 2 and 4). These holes 4 are made on site at a center distance corresponding to the center distance between two purlins. The fixing of panels according to the invention on purlins can therefore be carried out easily by the use of self-drilling screws 5 and self-tapping simply inserted into the holes 4 and actuated by means of a screwdriver or the like.
Sur sa face supérieure, opposée à celle de fixation sur les pannes 2, le bloc rigide 1 est pourvu de bossages 6 disposés en quinconce et déterminant entre - eux des passages longitudinaux et transversaux, avec formation de chicanes entre les passages transversaux, ces bossages 6 étant munis chacun d'une pluralité de fentes 7 ou autres ouvertures disposées en quinconce et destinées à la réception de moyens de montage de tuiles ou d'autres éléments de couverture (figures 2 à 6). La double disposition en quinconce des bossages 6 et des fentes 7 ou autres ouvertures permet d'obtenir un écartement entre les fentes 7 ou autres ouvertures de très faible module et, ainsi, une adaptation possible à toutes les dimensions possibles de couverture et d'écartement entre les supports de couverture. En outre, la disposition en quinconce des bossages 6 a pour effet de déterminer des canaux de circulation d'air sous la couverture, de sorte que la ventilation de la face interne de cette dernière est parfaitement assurée.On its upper face, opposite that of attachment to the purlins 2, the rigid block 1 is provided with bosses 6 staggered and determining between them longitudinal and transverse passages, with the formation of baffles between the transverse passages, these bosses 6 being each provided with a plurality of slots 7 or other openings arranged in staggered rows and intended for the reception of means for mounting tiles or other covering elements (FIGS. 2 to 6). The double staggered arrangement of the bosses 6 and the slots 7 or other openings makes it possible to obtain a spacing between the slots 7 or other very small module openings and, thus, possible adaptation to all the possible dimensions of coverage and spacing between the cover supports. In addition, the staggered arrangement of the bosses 6 has the effect of determining air circulation channels under the cover, so that the ventilation of the internal face of the latter is perfectly ensured.
De préférence, comme le montre la figure 3 des dessins annexés, les fentes 7 ou autres ouvertures sont pourvues chacune d'un évasement d'introduction 7' destiné à coopérer avec une partie de fixation correspondante de section correspondante de moyens de montage de tuiles ou d'autres éléments de couverture. Grâce à ces évasements 7', il est possible de guider facilement, lors de la mise en place de moyens de montage, les parties de fixation de ces derniers vers le fond des fentes 7 ou autres ouvertures. Par ailleurs, comme il ressort également des figures 1, 2 et 4 des dessins annexés, les bossages 6 peuvent être munis chacun d'une rainure 14 s'étendant suivant le sens longitudinal du bloc rigide 1. De telle rainures 14 permettent une mise en oeuvre des panneaux suivant l'axe des pannes 2 et un montage de moyens de support de couverture dans lesdites rainures parallèles 14.Preferably, as shown in FIG. 3 of the accompanying drawings, the slots 7 or other openings are each provided with an insertion flare 7 ′ intended to cooperate with a corresponding fixing part of corresponding section of tile mounting means or other cover elements. Thanks to these flares 7 ', it is possible to easily guide, during the installation of mounting means, the fixing parts of the latter towards the bottom of the slots 7 or other openings. Furthermore, as is also apparent from Figures 1, 2 and 4 of the accompanying drawings, the bosses 6 may each be provided with a groove 14 extending in the longitudinal direction of the rigid block 1. Such grooves 14 allow a setting work of the panels along the axis of the purlins 2 and an assembly of cover support means in said parallel grooves 14.
Selon une autre caractéristique de l'invention, les bords longitudinaux du bloc rigide 1 présentent avantageusement des profils complémentaires, l'un des bords étant pourvu d'une rainure ouverte vers le haut 8 destinée à former un canal d'évacuation d'humidité d'infiltration, l'autre bord étant muni d'une rainure 9 tournée vers le bas destinée à former un barrage pare-vapeur. Ainsi, lors de la juxtaposition des panneaux conformes à l'invention, leurs bords longitudinaux s'interpénétrent et coopèrent par forme, réalisant des joints longitudinaux parfaitement étanche à la traversée d'eau de ruissellement ou de condensation. En effet, la rainure ouverte vers le haut 8 prévue sur l'un des bords permet la récupération des infiltrations éventuelles et leur canalisation vers l'extrémité de la pente, dans une gouttière ou analogue, tandis que la rainure 9 tournée vers le bas de l'autre bord forme un piège à vapeur tendant à condenser cette dernière, de sorte que le condensât peut s'écouler sur la face correspondante de l'autre bord, d'où il sera dirigé vers la rainure 8 dudit bord. L'étanchéité de l'aboutement des panneaux est obtenu par injection entre les bords d'extrémité des panneaux d'un mastic ou d'une mousse expansible 10, comme le montre plus particulièrement la figure 5 des dessins annexés. H résulte d'un tel mode de réalisation que la continuité de l'étanchéité entre panneaux aboutés est parfaitement assurée. Conformément à une autre caractéristique de l'invention, le panneau coopère avec des moyens 11 de montage de tuiles 12 ou d'autres éléments de couverture, ces moyens 11 étant avantageusement chacun sous forme d'une réglette s'étendant transversalement à l'axe longitudinal du panneau et pourvue, à intervalles réguliers correspondants à ceux entre les fentes 7 ou autres ouvertures des bossages 6, d'au moins une rangée de pattes 12 destinées à coopérer avec lesdites fentes 7 ou autres ouvertures (figures 6 et 7).According to another characteristic of the invention, the longitudinal edges of the rigid block 1 advantageously have complementary profiles, one of the edges being provided with a groove open upwards 8 intended to form a moisture evacuation channel d 'infiltration, the other edge being provided with a groove 9 facing downwards intended to form a vapor barrier. Thus, during the juxtaposition of the panels according to the invention, their longitudinal edges interpenetrate and cooperate by shape, producing longitudinal joints that are perfectly sealed at the crossing of runoff or condensation water. Indeed, the groove open upwards 8 provided on one of the edges allows the recovery of possible infiltrations and their channeling towards the end of the slope, in a gutter or the like, while the groove 9 turned towards the bottom of the other edge forms a vapor trap tending to condense the latter, so that the condensate can flow on the corresponding face of the other edge, from where it will be directed towards the groove 8 of said edge. The sealing of the abutment of the panels is obtained by injection between the end edges of the panels of a sealant or an expandable foam 10, as shown more particularly in Figure 5 of the accompanying drawings. It results from such an embodiment that the continuity of the seal between butted panels is perfectly ensured. According to another characteristic of the invention, the panel cooperates with means 11 for mounting tiles 12 or other covering elements, these means 11 being advantageously each in the form of a strip extending transversely to the axis. longitudinal of the panel and provided, at regular intervals corresponding to those between the slots 7 or other openings of the bosses 6, at least one row of lugs 12 intended to cooperate with said slots 7 or other openings (Figures 6 and 7).
Comme le montre plus particulièrement la figure 7 des dessins annexés, la réglette formant un moyen 11 est préférentiellement pourvue de deux rangées de pattes 13 espacées selon un module correspondant à l'écartement entre au moins deux fentes 7 ou autres ouvertures d'un bossage 6. Une telle prévision de deux rangées de pattes 13 permet une meilleure fixation du moyen II sur le panneau et d'assurer son maintien sans dispositif de fixation complémentaire. Selon une caractéristique de l'invention, la ou les rangées de pattes 13 sont disposées suivant un ou des axes excentrés par rapport au plan médian de la réglette formant le moyen 11. Cette caractéristique apparaît plus particulièrement sur la figure 7 des dessins. Ainsi, l'écartement mutuel des moyens 11 sur un panneau en fonction de l'espace entre appuis des éléments de couverture mis en oeuvre peut être modulé d'un cran supplémentaire et permettre une adaptation très fine aux besoins.As shown more particularly in Figure 7 of the accompanying drawings, the strip forming a means 11 is preferably provided with two rows of legs 13 spaced apart according to a module corresponding to the spacing between at least two slots 7 or other openings of a boss 6 Such a provision of two rows of legs 13 allows better fixing of the means II on the panel and ensuring its maintenance without additional fixing device. According to a characteristic of the invention, the row or rows of tabs 13 are arranged along one or more axes which are offset relative to the median plane of the strip forming the means 11. This characteristic appears more particularly in FIG. 7 of the drawings. Thus, the mutual spacing of the means 11 on a panel as a function of the space between supports of the covering elements used can be modulated by an additional notch and allow very fine adaptation to needs.
Grâce à l'invention, il est possible de réaliser un panneau isolant autoporteur pour toiture permettant la mise en oeuvre de tous types de couverture et dont la rigidité longitudinale est suffisante pour assurer la résistance nécessaire aux charges.Thanks to the invention, it is possible to produce a self-supporting insulating panel for roofing allowing the implementation of all types of roofing and whose longitudinal rigidity is sufficient to ensure the necessary resistance to loads.
En outre, comme le montre plus particulièrement la figure 6 des dessins annexés, les profilés 3 de reprise des efforts, qui sont insérés dans le bloc rigide 1 en matériau isolant, permettent la fixation d'éléments de décoration ou de finition intérieurs, directement par application de ces éléments sur lesdits profilés ou avec interposition des pannes 2 de soutien, par vissage sur lesdits profilés.In addition, as shown more particularly in Figure 6 of the accompanying drawings, the profiles 3 of force recovery, which are inserted in the rigid block 1 of insulating material, allow the fixing of interior decoration or finishing elements, directly by application of these elements on said profiles or with interposition of the support 2 purlins, by screwing on said profiles.
Le panneau conforme à l'invention présente l'avantage d'être d'un très faible poids relativement à ses dimensions, de sorte qu'il peut facilement être manutentionné par un opérateur seul et sa mise en oeuvre facile et rapide permet d'importants gains de productivité entraînant une minoration correspondante des coûts de construction.The panel according to the invention has the advantage of being very light in relation to its dimensions, so that it can easily be handled by an operator alone and its easy and rapid implementation allows important productivity gains resulting in a corresponding reduction in construction costs.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.
