Description

Domaine techniqueTechnical area

La présente invention concerne le domaine général du bâtiment, et plus particulièrement un panneau composite autoportant de toiture.The present invention relates to the general field of the building, and more particularly to a self-supporting composite roofing panel.

Technique antérieurePrior art

Dans le domaine de la couverture de maisons ou de bâtiments, il est connu d'utiliser des panneaux composites autoportants aptes à recevoir ou non une couverture classique du type tuile par exemple.In the field of the roofing of houses or buildings, it is known to use self-supporting composite panels capable of receiving or not a conventional roof type tile for example.

Ces panneaux composites connus, qui sont de plus en plus utilisés dans des maisons individuelles à plafond rampant ou à combles aménageables, remplissent de manière classique les fonctions suivantes :

  • portance : le panneau composite assure en partie la portance entre les éléments de charpente,
  • isolation thermique : le panneau composite comprend un isolant thermique,
  • parement intérieur : le panneau composite est prêt à recevoir les finitions intérieures,
  • contre liteaunage : le panneau composite doit pouvoir recevoir les liteaux (ou lattes) pour répondre à tous les types de couvertures en petits éléments tels que, par exemple, des tuiles,
  • étanchéité : le panneau composite doit assurer les fonctions de pare-pluie et pare-neige.
These known composite panels, which are increasingly used in individual homes with crawling ceiling or attic conversion, typically fulfill the following functions:
  • lift: the composite panel partly provides the lift between the structural elements,
  • thermal insulation: the composite panel includes thermal insulation,
  • interior siding: the composite panel is ready to receive interior finishes,
  • against liteaunage: the composite panel must be able to receive the battens (or laths) to meet all types of blankets in small elements such as, for example, tiles,
  • waterproof: the composite panel must provide the functions of rain and snow.

Si chacun de ces panneaux connus est étanche, l'assemblage d'un de ces panneaux avec un panneau semblable adjacent n'est pas toujours d'une étanchéité efficace. En effet, l'étanchéité entre ces panneaux connus est réalisée, de manière classique, lors du montage de ces derniers sur une charpente par la mise en place entre lesdits panneaux adjacents d'un cordon de mousse expansive.If each of these known panels is waterproof, the assembly of one of these panels with an adjacent similar panel is not always effective sealing. Indeed, the sealing between these known panels is carried out, conventionally, during the assembly of the latter on a frame by the establishment between said adjacent panels of an expansive foam bead.

Toutefois, cette technique présente les inconvénients d'être longue à mettre en oeuvre et d'avoir une efficacité qui dépend principalement du professionnalisme de l'équipe de monteurs. En effet, si les monteurs ne font pas correctement les cordons de mousse expansive, l'étanchéité à l'eau et surtout à l'air entre les panneaux ne sera pas garantie, ce qui est préjudiciable dans les maisons d'habitations modernes à basse consommation d'énergie, dites BBC, construites dans le respect de la Réglementation Thermique RT2012 mise en place à la suite du Grenelle de l'Environnement.However, this technique has the disadvantages of being long to implement and have an efficiency that depends mainly on the professionalism of the team of editors. In fact, if the assemblers do not make the expansive foam cords correctly, the watertightness and especially the airtightness between the panels will not be guaranteed, which is detrimental in modern low-rise houses. energy consumption, so-called BBC, built in compliance with the RT2012 Thermal Regulation set up following the Grenelle de l'Environnement.

En outre, les panneaux connus, qui sont prévus pour être fixés sur et entre les éléments de charpente en bois, ne permettent pas nécessairement de réaliser des parties en porte à faux le long des bords des toitures.In addition, the known panels, which are intended to be fixed on and between the timber frame members, do not necessarily make it possible to make cantilevered parts along the edges of the roofs.

On comprend bien que le traitement actuel des jonctions entre panneaux adjacents avec un cordon de mousse expansive ne permet pas de garantir une isolation thermique continue sur l'ensemble de la toiture.It is understood that the current treatment of junctions between adjacent panels with an expansive foam bead does not ensure a continuous thermal insulation on the entire roof.

Enfin, On connaît également des panneaux composites connus tels que ceux décrits dans la demande de brevet allemand DE 30 11 159 présentant des bords longitudinaux spécifiques. Toutefois, ces derniers ne garantissent pas une étanchéité avec les panneaux adjacents.Finally, known composite panels such as those described in the German patent application are also known. DE 30 11 159 with specific longitudinal edges. However, these do not guarantee a seal with the adjacent panels.

Exposé de l'inventionPresentation of the invention

Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de présenter une alternative aux panneaux de toiture existants en proposant un panneau composite autoportant facile et rapide à mettre en oeuvre avec peu de main d'oeuvre, permettant de réaliser une mise hors d'eau d'un bâtiment en une seule opération, et garantissant une parfaite étanchéité à l'eau et à l'air.The purpose of the present invention is therefore to overcome the aforementioned drawbacks and to present an alternative to existing roof panels by proposing a self-supporting composite panel easy and quick to implement with little labor, to achieve a bet out of water of a building in a single operation, and guaranteeing a perfect water and air tightness.

A cet égard, la présente invention a pour objet un panneau composite autoportant agencé pour être fixé au moins sur la sablière et la faitière de la charpente d'une maison d'habitation pour former sa toiture et comportant au moins un élément en forme globale de parallélépipède allongé comprenant une face intérieure, une face extérieure et des bords latéraux et longitudinaux reliant entre elles lesdites faces intérieure et extérieure, l'un desdits bords longitudinaux comportant une première découpe longitudinale en forme de J aménagée du côté de ladite face intérieure et une deuxième découpe longitudinale en forme de J aménagée du côté de la face extérieure, ledit panneau composite autoportant étant remarquable en ce que ledit bord longitudinal comporte une découpe intermédiaire longitudinale rejoignant les première et deuxième découpes longitudinales et ayant une section transversale en forme de N incliné, et en ce que l'autre bord longitudinal a une section transversale de forme complémentaire à celle dudit bord longitudinal.In this regard, the present invention relates to a self-supporting composite panel arranged to be fixed at least on the sandpit and the frame of a dwelling house to form its roof and comprising at least one elongate parallelepiped shaped element comprising an inner face, an outer face and lateral and longitudinal edges interconnecting said inner and outer faces, one of said longitudinal edges having a first longitudinal cut in the shape of J arranged on the side of said inner face and a second longitudinal cut in the shape of J arranged on the side of the outer face, said self-supporting composite panel being remarkable in that said longitudinal edge comprises a longitudinal intermediate cut-out joining the first and second longitudinal cut-outs and having an inclined N-shaped cross-section, and in that the other longitudinal edge has a cross-section of shape complementary to that of said longitudinal edge .

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

En référence aux figures 1 et 5, on a représenté une maison d'habitation 1 comportant des murs 2 de façade sur lesquels repose une charpente 3 recouverte en partie par des panneaux composites autoportants 10 selon l'invention formant la toiture 4 de ladite maison d'habitation 1, ladite charpente 3 comportant une pluralité d'éléments classiquement en bois tels que, par exemple, des sablières 5, des pannes intermédiaires 6 ou encore des faitières 7.With reference to figures 1 and 5 , there is shown a dwelling house 1 having walls 2 front on which rests a frame 3 partially covered by self-supporting composite panels 10 according to the invention forming the roof 4 of said dwelling house 1, said frame 3 comprising a plurality of elements conventionally made of wood such as, for example, sablières 5, intermediate failures 6 or stilles 7.

Les panneaux composites autoportants 10 selon l'invention pourront également être utilisés pour recouvrir un bâtiment d'un tout autre type tel que, par exemple, un bâtiment de bureau ou encore un bâtiment industriel, sans sortir du cadre de la présente invention.The self-supporting composite panels 10 according to the invention may also be used to cover a building of any other type such as, for example, a office building or an industrial building, without departing from the scope of the present invention.

En référence aux figures 2 à 5, chaque panneau composite autoportant 10 selon l'invention comporte au moins un élément 11 en forme globale de parallélépipède allongé comprenant une face intérieure 12 et une face extérieure 13 parallèles entre elles ou non, des bords latéraux 14 et des bords longitudinaux 15,16 reliant entre elles lesdites faces intérieure et extérieure 12,13.With reference to Figures 2 to 5 each self-supporting composite panel 10 according to the invention comprises at least one element 11 in the overall shape of an elongate parallelepiped comprising an inner face 12 and an outer face 13 parallel to each other or not, lateral edges 14 and longitudinal edges 15, 16 connecting between them said inner and outer faces 12,13.

Lesdits bords latéraux 14 sont de préférence globalement plans (Cf. figure 5), mais ils pourront toutefois avoir une section transversale plus ou moins courbe pour permettre, par exemple, la pose d'accessoires de toiture, sans sortir du cadre de la présente invention. On entend ici par "intérieur(e)" et "extérieur(e)" un élément ou une partie d'un élément constitutif du panneau composite autoportant 10 se situant réciproquement du côté intérieur et du côté extérieur de la maison d'habitation 1, lorsque le panneau composite autoportant 10 est mis en place sur la charpente 3 de ladite maison d'habitation 1.Said lateral edges 14 are preferably generally planar (Cf. figure 5 ), but they may however have a cross section more or less curved to allow, for example, the installation of roofing accessories, without departing from the scope of the present invention. Here "inner (e)" and "outer (e)" mean an element or a part of a constituent element of the self-supporting composite panel 10 lying reciprocally on the inner side and on the outer side of the dwelling house 1, when the self-supporting composite panel 10 is put in place on the frame 3 of said dwelling house 1.

Par ailleurs, chaque élément 11 est composé d'une pluralité de couches assemblées entre elles par toute technique adaptée telle que, par exemple, le collage, le thermocollage ou encore le vissage.Furthermore, each element 11 is composed of a plurality of layers assembled together by any suitable technique such as, for example, gluing, heat sealing or screwing.

Ainsi, de sa face intérieure 12 à sa face extérieure 13, chaque élément 11 du panneau composite autoportant 10 est multicouche et comporte avantageusement au moins les couches suivantes :

  • une couche de parement intérieur 17,
  • une première couche de renfort 18,
  • une couche isolante 19,
  • une deuxième couche de renfort 20,
  • une couche de parement extérieur 21,
  • une couche de sous-couverture phonique 22,
  • une couche écran de sous toiture 23,
  • une couche de lattes longitudinales 24, et
  • une couche de voliges 25 et/ou panneaux permettant la mise en place des éléments de couverture du type tuile, par exemple, ou pour créer des réservations pour la mise en place de fenêtre de toit ou encore de conduit de cheminée.
Thus, from its inner face 12 to its outer face 13, each element 11 of the self-supporting composite panel 10 is multilayer and advantageously comprises at least the following layers:
  • an inner facing layer 17,
  • a first reinforcing layer 18,
  • an insulating layer 19,
  • a second reinforcing layer 20,
  • an outer facing layer 21,
  • a layer of phonic sub-coverage 22,
  • a screen layer of under-roof 23,
  • a layer of longitudinal slats 24, and
  • a layer of fences 25 and / or panels allowing the introduction of roofing elements of the tile type, for example, or to create reservations for the installation of roof window or chimney.

La face intérieure 12 est déterminée par la couche de l'élément 11 située le plus à l'intérieur, à savoir dans l'exemple décrit la couche de parement intérieur 17.The inner face 12 is determined by the innermost layer of the element 11, namely in the example described the inner facing layer 17.

De façon analogue, la face extérieure 13 est déterminée par la couche de l'élément 11 située le plus à l'extérieur, à savoir dans l'exemple décrit la couche de voliges 25.Similarly, the outer face 13 is determined by the layer of the outermost element 11, namely in the example described the layer of battens 25.

La couche de parement intérieur 17 est la couche finie ou semi-finie qui est visible depuis l'intérieur de la maison d'habitation 1 lorsque le panneau composite autoportant 10 est mis en place sur la charpente 3 de ladite maison d'habitation 1. Ladite couche de parement intérieur 17 peut donc être constituée d'une plaque de différentes épaisseurs en différents matériaux tels que, par exemple, du plâtre, du métal, du bois aggloméré, ou encore du bois mais de différentes essences. Pour des raisons principalement économiques, ladite couche de parement intérieur 17 est constituée de manière avantageuse d'une plaque d'épicéa de 20 mm d'épaisseur pouvant être brut, recouverte de peinture ou vernis, ou encore structurée avec éléments décoratifs ou phoniques.The inner facing layer 17 is the finished layer or semi-finished which is visible from the interior of the dwelling house 1 when the self-supporting composite panel 10 is put in place on the frame 3 of said dwelling house 1. Said inner facing layer 17 may be constituted a plate of different thicknesses in different materials such as, for example, plaster, metal, chipboard, or wood but different species. For mainly economic reasons, said inner facing layer 17 advantageously consists of a spruce plate 20 mm thick which can be rough, covered with paint or varnish, or structured with decorative or phonic elements.

La première couche de renfort 18 est une couche qui contribue à conférer à chaque élément 11 du panneau composite autoportant 10 de la stabilité et de la rigidité longitudinale et transversale. Cette première couche de renfort 18 peut donc être constituée d'une plaque de différentes épaisseurs en différents matériaux tels que, par exemple, du bois massif de différentes essences, du bois aggloméré ou encore du métal. Pour des raisons de résistance mécanique, ladite couche de renfort 18 est avantageusement constituée d'une plaque de contreplaqué brut de 5 mm d'épaisseur.The first reinforcing layer 18 is a layer which contributes to giving each element 11 of the self-supporting composite panel 10 stability and longitudinal and transverse rigidity. This first reinforcing layer 18 may therefore consist of a plate of different thicknesses of different materials such as, for example, solid wood of different species, agglomerated wood or metal. For reasons of mechanical strength, said reinforcing layer 18 is advantageously constituted by a plywood plate 5 mm thick.

Pour des raisons évidentes d'économie et de rationalisation de la fabrication, la deuxième couche de renfort 20 est de préférence identique à la première couche de renfort 18.For obvious reasons of economy and rationalization of the manufacture, the second reinforcing layer 20 is preferably identical to the first reinforcing layer 18.

Toutefois, pour des raisons de résistance au feu de chaque élément 11 du panneau composite autoportant 10, les première et deuxième couches de renfort 18,20 pourront ne pas être identiques, sans sortir du cadre de la présente invention. La couche isolante 19 est la couche qui permet en grande partie d'obtenir pour chaque élément 11 du panneau composite autoportant 10 le niveau d'isolation thermique souhaité. Cette couche isolante 19 se compose de préférence d'une plaque de polystyrène expansé (PSE). Le polystyrène expansé est avantageusement du type graphité, de densité 25 kg/m3 minimum et ignifugé c'est-à-dire auto-extinguible (ne propageant pas le feu). Par ailleurs, le polystyrène expansé est particulièrement intéressant car il comporte 96 à 98 % d'air sec statique et uniquement 2 à 4 % de matière synthétique et il est exempt de chlorofluorocarbures (CFC) responsable en partie de la destruction de la couche d'ozone. En outre, le polystyrène expansé ne constitue pas un bouillon de culture pour les animaux nuisibles, les plantes, ou les micro-organismes, il est imputrescible, pérenne et totalement recyclable.However, for reasons of fire resistance of each element 11 of the self-supporting composite panel 10, the first and second reinforcement layers 18,20 may not be identical, without departing from the scope of the present invention. The insulating layer 19 is the layer which makes it possible in large part to obtain for each element 11 of the panel self-supporting composite 10 the desired level of thermal insulation. This insulating layer 19 preferably consists of an expanded polystyrene plate (EPS). The expanded polystyrene is advantageously of the graphite type, with a minimum density of 25 kg / m3 and flame retarded, that is to say self-extinguishing (not spreading fire). Furthermore, expanded polystyrene is particularly interesting because it comprises 96 to 98% static dry air and only 2 to 4% of synthetic material and it is free of chlorofluorocarbons (CFC) responsible in part for the destruction of the coating layer. ozone. In addition, expanded polystyrene is not a culture broth for pests, plants, or micro-organisms, it is rot-proof, durable and fully recyclable.

L'épaisseur de la couche isolante 19 sera adaptée pour obtenir une résistance thermique R correspondant à ladite isolation thermique. Ainsi, le tableau suivant donne la valeur de résistance R en m2.K/W (Mètre carré-Kelvin par Watt) en fonction de l'épaisseur de la plaque de PSE : Epaisseur plaque PSE (mm) Résistance thermique R (m2.K/W) 181 7, 14 215 8, 12 270 9, 89 280 10, 21 The thickness of the insulating layer 19 will be adapted to obtain a thermal resistance R corresponding to said thermal insulation. Thus, the following table gives the resistance value R in m2.K / W (square meter-Kelvin per Watt) as a function of the thickness of the EPS plate: PSE plate thickness (mm) Thermal resistance R (m2.K / W) 181 7, 14 215 8, 12 270 9, 89 280 10, 21

La couche isolante 19 pourra également être composée de plusieurs plaques assemblées entre elles de façon superposée, ces dernières pouvant être de différentes matières et/ou épaisseurs. Cette configuration particulière permet, par exemple, d'obtenir, pour une épaisseur donnée, une résistance thermique R plus élevée que celle donnée dans le tableau précédent.The insulating layer 19 may also be composed of several plates assembled together superimposed, the latter may be of different materials and / or thicknesses. This particular configuration makes it possible, for example, to obtain, for a given thickness, a higher thermal resistance R than that given in the preceding table.

Pour des raisons évidentes d'économie et de rationalisation de la fabrication, la couche de parement extérieur 21 est de préférence identique à la couche de parement intérieur 17. Toutefois, cette couche de parement extérieur 21 est évidemment brute puisque non visible.For obvious reasons of economy and rationalization of the manufacture, the outer facing layer 21 is preferably identical to the inner facing layer 17. However, this outer facing layer 21 is obviously gross since not visible.

La couche de sous-couverture phonique 22 est mise en oeuvre pour réaliser l'isolation acoustique entre l'extérieur et l'intérieur de la maison d'habitation 1. Pour des raisons écologiques et de tenue mécanique, ladite couche de sous-couverture phonique 22 est constituée de préférence d'une plaque de fibre de bois d'épaisseur 35 mm.The sound sub-cover layer 22 is used to achieve the acoustic insulation between the outside and the inside of the dwelling house 1. For ecological and mechanical reasons, said layer of sound under-coverage 22 is preferably a 35 mm thick wood fiber board.

La couche écran de sous toiture 23 est imperméable à l'eau afin d'éviter l'entrée d'eau à l'intérieur de la maison d'habitation 1. Selon un mode de réalisation avantageux, la couche écran de sous toiture 23 est constituée par une toile souple ou similaire. Ladite couche écran de sous toiture 23 s'étend au-delà de l'élément 11 du panneau composite autoportant 10 pour permettre un recouvrement en partie du ou des éléments 11 adjacents pour assurer la continuité de l'étanchéité (Cf. figures 4 et 5).The under-roofing screen layer 23 is impermeable to water in order to prevent the entry of water into the dwelling house 1. According to an advantageous embodiment, the under-roof screen layer 23 is constituted by a flexible fabric or the like. Said under-roof screen layer 23 extends beyond the element 11 of the self-supporting composite panel 10 so as to allow part of the adjacent element (s) 11 to overlap to ensure continuity of the seal (Cf. figures 4 and 5 ).

La couche de lattes longitudinales 24 est constituée par une pluralité de lattes 24 en bois, de préférence trois, espacées parallèlement entre elles et s'étendant le long de la longueur de l'élément 11 associé. Cette couche de lattes longitudinales 24 permet la mise en place éventuelle de la couche de voliges 25. Ces lattes longitudinales 24 participent également, en faisant office de renfort mécanique longitudinal, à la fixation des éléments 11 et/ou des panneaux composites autoportants 10 entre eux et/ou sur la charpente 3 de ladite maison d'habitation 1.The layer of longitudinal slats 24 is constituted by a plurality of slats 24 of wood, preferably three, spaced parallel to each other and extending along the length of the associated element 11. This layer of longitudinal slats 24 allows for the possible installation of the layer of battens 25. These longitudinal slats 24 also participate, by making longitudinal mechanical reinforcing office, the attachment of the elements 11 and / or self-supporting composite panels 10 between them and / or on the frame 3 of said dwelling house 1.

La couche de voliges 25 est constituée par une pluralité de lattes 25 en bois espacées parallèlement entre elles et s'étendant perpendiculairement auxdites lattes longitudinales 24 et permettant la mise en place des éléments de couverture du type tuile, leurs espacement et nombre dépendant des dimensions dudit élément de couverture retenus par le propriétaire de la maison d'habitation 1.The layer of battens 25 is constituted by a plurality of wooden slats 25 spaced parallel to each other and extending perpendicularly to said longitudinal slats 24 and allowing the introduction of the roofing elements of the tile type, their spacing and number depending on the dimensions of said roof element retained by the owner of the dwelling house 1.

En outre, lesdits bords longitudinaux 15,16 de chaque élément 11 sont de forme spécifique de manière à permettre à la fois une jonction aisée avec un élément adjacent et une étanchéité à l'air assurée entre deux éléments 11 adjacents, quelle que soit l'équipe de monteurs employée pour mettre en place le panneau composite autoportant 10 sur la maison d'habitation 1In addition, said longitudinal edges 15,16 of each element 11 are of specific shape so as to allow both an easy connection with an adjacent element and an airtightness assured between two adjacent elements 11, whatever the team of fitters used to set up the freestanding composite panel 10 on the dwelling house 1

Pour ce faire, les bords longitudinaux 15,16 de chaque élément 11 ont des sections transversales de forme complémentaire, c'est-à-dire que, en référence à la figure 4, le bord longitudinal 16 de l'élément 11 coopère avec le bord longitudinal 15' d'un élément 11' adjacent en s'engageant au moins en partie dans ce dernier (Cf. figure 4) de manière à ce que leurs faces intérieures 12,12' et extérieures 13,13' soient coplanaires lorsque les deux éléments 11,11' sont assemblés.To do this, the longitudinal edges 15, 16 of each element 11 have cross-sections of complementary shape, that is to say that, with reference to the figure 4 , the longitudinal edge 16 of the element 11 cooperates with the longitudinal edge 15 'of an adjacent element 11' engaging at least partly in the latter (Cf. figure 4 ) so that their inner faces 12,12 'and outer 13,13' are coplanar when the two elements 11,11 'are assembled.

Ainsi, en référence à la figure 3, le bord longitudinal 15 comporte une première découpe longitudinale 26 en forme de J aménagée du côté de la face intérieure 12 de l'élément 11, de préférence dans la couche de parement intérieur 17, une deuxième découpe longitudinale 27 en forme de J aménagée du côté de la face extérieure 13 de l'élément 11, de préférence jusqu'à la couche de parement extérieur 21, et une découpe intermédiaire 28 globalement inclinée rejoignant les première et deuxième découpes longitudinales 26,27.So, with reference to the figure 3 , the longitudinal edge 15 has a first longitudinal cutout 26 in the shape of J arranged on the side of the inner face 12 of the element 11, preferably in the inner facing layer 17, a second longitudinal cutout 27 in the shape of a J arranged in the side of the outer face 13 of the element 11, preferably to the outer facing layer 21, and an intermediate cutout 28 generally inclined joining the first and second longitudinal cutouts 26,27.

Ladite découpe intermédiaire 28 a une section transversale en forme de N incliné et comporte donc une première face inclinée 29, une deuxième face inclinée 30 et une troisième face inclinée 31.Said intermediate cutout 28 has an inclined N-shaped cross-section and therefore comprises a first inclined face 29, a second inclined face 30 and a third inclined face 31.

Ladite première face inclinée 29 est issue du bord longitudinal de la première découpe longitudinale 26 situé du côté de la face extérieure 13 de l'élément 11 et s'étend en direction de cette dernière et de l'intérieur dudit élément 11.Said first inclined face 29 is derived from the longitudinal edge of the first longitudinal cut 26 located on the side of the outer face 13 of the element 11 and extends towards the latter and the inside of said element 11.

Ladite deuxième face inclinée 30 est issue du bord longitudinal libre de la première face inclinée 29 et s'étend en direction de la face intérieure 12 de l'élément 11 et de l'intérieur de ce dernier.Said second inclined face 30 is derived from the free longitudinal edge of the first inclined face 29 and extends in the direction of the inner face 12 of the element 11 and the interior of the latter.

Enfin, ladite troisième face inclinée 31 est issue du bord longitudinal libre de la deuxième face inclinée 30 et s'étend en direction de la face extérieure 13 de l'élément 11 et de l'intérieur de ce dernier, jusqu'à rejoindre le bord longitudinal de la deuxième découpe longitudinale 27 situé du côté de la face intérieure 12 de l'élément 11.Finally, said third inclined face 31 is derived from the free longitudinal edge of the second inclined face 30 and extends towards the outer face 13 of the element 11 and the inside of the latter, until reaching the edge longitudinal of the second longitudinal cutout 27 located on the side of the inner face 12 of the element 11.

De manière analogue, le bord longitudinal 16, qui a une forme complémentaire à celle du bord longitudinal 15, comporte donc une première découpe longitudinale 32 en forme de J pivoté de 90° dans le sens horaire et aménagée du côté de la face intérieure 12 de l'élément 11, de préférence dans la couche de parement intérieur 17, une deuxième découpe longitudinale 33 en forme de J pivoté de 90° dans le sens horaire et aménagée du côté de la face extérieure 13 de l'élément 11, de préférence jusqu'à la couche de parement extérieur 21, et une découpe intermédiaire 34 globalement inclinée rejoignant les première et deuxième découpes longitudinales 32,33.Similarly, the longitudinal edge 16, which has a shape complementary to that of the longitudinal edge 15, thus comprises a first longitudinal cut 32 J-shaped rotated 90 ° clockwise and arranged on the side of the inner face 12 of the element 11, preferably in the inner facing layer 17, a second longitudinal cut 33 in the shape of a J rotated 90 ° in the clockwise direction and arranged on the side of the outer face 13 of the element 11, preferably up to to the outer facing layer 21, and an intermediate generally inclined cutout 34 joining the first and second longitudinal cutouts 32,33.

Ladite découpe intermédiaire 34 a également une section transversale en forme de N incliné et comporte donc une première face inclinée 35, une deuxième face inclinée 36 et une troisième face inclinée 37.Said intermediate cutout 34 also has an inclined N-shaped cross section and thus comprises a first inclined face 35, a second inclined face 36 and a third inclined face 37.

Ladite première face inclinée 35 est issue du bord longitudinal de la première découpe longitudinale 32 situé du côté de la face extérieure 13 de l'élément 11 et s'étend en direction de cette dernière et de l'extérieur dudit élément 11.Said first inclined face 35 is derived from the longitudinal edge of the first longitudinal cutout 32 located on the side of the outer face 13 of the element 11 and extends towards the latter and outside said element 11.

Ladite deuxième face inclinée 36 est issue du bord longitudinal libre de la première face inclinée 35 et s'étend en direction de la face intérieure 13 de l'élément 11 et de l'extérieur de ce dernier.Said second inclined face 36 is derived from the free longitudinal edge of the first inclined face 35 and extends towards the inner face 13 of the element 11 and the outside of the latter.

Enfin, ladite troisième face inclinée 37 est issue du bord longitudinal libre de la deuxième face inclinée 36 et s'étend en direction de la face extérieure 13 de l'élément 11 et de l'intérieur de ce dernier, jusqu'à rejoindre le bord longitudinal de la deuxième découpe longitudinale 33 situé du côté de la face intérieure 12 de l'élément 11.Finally, said third inclined face 37 is derived from the free longitudinal edge of the second inclined face 36 and extends towards the outer face 13 of the element 11 and from inside the latter, until reaching the edge longitudinal of the second longitudinal cutout 33 located on the side of the inner face 12 of the element 11.

En référence à la figure 4, la jonction longitudinale entre deux éléments 11,11' adjacents est obtenue en rapprochant ces derniers en mettant en appui les première et troisième faces inclinées 35,37 du bord longitudinal 16 de l'élément 11 contre les première et troisième faces inclinées 29',31' du bord longitudinal 15' de l'élément 11', jusqu'à ce que la deuxième face inclinée 36 dudit bord longitudinal 16 vienne en contact avec la deuxième face inclinée 30' dudit bord longitudinal 15'.With reference to the figure 4 the longitudinal junction between two adjacent elements 11, 11 'is obtained by bringing the latter closer together by placing the first and third inclined faces 35, 37 of the longitudinal edge 16 of the element 11 against the first and third inclined faces 29', 31 'of the longitudinal edge 15' of the element 11 ', until the second inclined face 36 of said longitudinal edge 16 comes into contact with the second inclined face 30' of said longitudinal edge 15 '.

On comprend bien que la forme en N incliné de la section transversale des découpes intermédiaires 28,34 respectives des bords longitudinaux 15,16 est intéressante car, une fois les éléments 11,11' adjacents assemblés, cela garantit l'étanchéité de la jonction longitudinale desdits éléments 11,11' en constituant une chicane limitant voire empêchant tout passage d'eau et/ou d'air.It is well understood that the inclined N-shape of the cross-section of the respective intermediate cutouts 28, 34 of the longitudinal edges 15, 16 is of interest because, once the elements 11, 11 'are assembled together, this guarantees the tightness of the longitudinal junction. said elements 11,11 'constituting a baffle limiting or even preventing any passage of water and / or air.

Pour accroitre l'étanchéité à l'air de cette jonction, des joints d'étanchéité 38 sont de préférence mis en place dans les première et deuxième découpes longitudinales 26',27' du bord longitudinal 15' de l'élément 11' et comprimés respectivement par les première et deuxième découpes longitudinales 32,33 du bord longitudinal 16 de l'élément 11.To increase the airtightness of this junction, seals 38 are preferably placed in the first and second longitudinal cutouts 26 ', 27' of the longitudinal edge 15 'of the element 11' and compressed respectively by the first and second longitudinal cutouts 32, 33 of the longitudinal edge 16 of the element 11.

Pour solidariser les deux éléments 11,11' adjacents entre eux, un organe de fixation, non représenté, du type vis par exemple, est mis en place au droit de la jonction des bords longitudinaux 15',16 le long du trait d'axe A-A' de la figure 4 de sorte à traverser au moins en partie lesdits deux éléments 11,11', ledit organe de fixation permettant également de comprimer les joints d'étanchéité 38.To secure the two elements 11,11 'adjacent to each other, a fixing member, not shown, of the screw type for example, is put in place at the junction of the longitudinal edges 15 ', 16 along the center line AA' of the figure 4 so as to pass at least in part said two elements 11,11 ', said fixing member also for compressing the seals 38.

Toutefois, pour garantir la solidité de cette solidarisation, les première 29,29' et deuxième faces inclinées 30,30' du bord longitudinal 15,15' de chaque élément 11,11' sont déterminées par une latte de renfort 39,39' fixée sur la première couche de renfort 18 et contre la couche isolante 19. Ladite latte de renfort 39,39' est avantageusement en bois massif pour permettre une bonne prise dudit organe de fixation.However, to ensure the solidity of this connection, the first 29,29 'and second inclined faces 30,30' of the longitudinal edge 15,15 'of each element 11,11' are determined by a reinforcement lath 39,39 'fixed on the first reinforcing layer 18 and against the insulating layer 19. Said reinforcing strip 39,39 'is preferably solid wood to allow a good grip of said fastener.

Chaque élément 11 mesure environ 120 cm de large et sa longueur correspond à la longueur du pan de la toiture 4.Each element 11 is approximately 120 cm wide and its length corresponds to the length of the pan of the roof 4.

Chaque panneau composite autoportant 10 peut selon les besoins comporter un ou deux éléments 11. De plus, on comprend bien que l'élément 11 du panneau composite autoportant 10 disposé au bord de la toiture 4 de la maison d'habitation 1 pourra comporter un bord longitudinal 15 ou 16 sensiblement plan pour permettre la mise en place de planche de rive, non représentée, le long des bords de la toiture 4, sans sortir du cadre de la présente invention.Each self-supporting composite panel 10 may, as required, comprise one or two elements 11. Moreover, it is well understood that the element 11 of the self-supporting composite panel 10 disposed at the edge of the roof 4 of the residential house 1 may comprise an edge longitudinal 15 or 16 substantially planar to allow the establishment of edge board, not shown, along the edges of the roof 4, without departing from the scope of the present invention.

Enfin, en référence à la figure 5, chaque panneau composite autoportant 10 est fixé au moins sur la sablière 5 et la faitière 7 de la charpente 3 par un organe de fixation, non représenté, du type vis par exemple, mis en place au moins au droit de la jonction des bords longitudinaux de panneaux composites autoportants 10 adjacents, le long d'au moins chaque trait d'axe de la figure 5 de sorte à traverser lesdits deux éléments 11,11' au niveau des lattes montantes 24 et au moins en partie la sablière 5 ou faitière 7 associée.Finally, with reference to figure 5 , each self-supporting composite panel 10 is fixed at least on the sandbox 5 and the ridge 7 of the frame 3 by a fastener, not shown, of the screw type for example, set up at least at the junction of the longitudinal edges of adjacent self-supporting composite panels 10 along at least each center line of the figure 5 so as to pass through said two elements 11,11 'at the level of the rising slats 24 and at least partly the associated sand pit 5 or screed 7.

Pour faciliter la mise en place de chaque panneau composite autoportant 10 sur la charpente 3, la couche de parement intérieur 17 est munie d'une rainure 40 aménagée transversalement au voisinage de l'une de ses extrémités longitudinales et agencée pour coopérer avec un tasseau 8 disposé au moins en partie en saillie sur le dessus de la sablière 5 associée de la charpente 3 pour maintenir le panneau composite autoportant 10 en position sur cette dernière, avant la mise en place des organes de fixation.To facilitate the setting up of each panel self-supporting composite 10 on the frame 3, the inner facing layer 17 is provided with a groove 40 arranged transversely in the vicinity of one of its longitudinal ends and arranged to cooperate with a cleat 8 disposed at least partly projecting on the above the associated sill 5 of the frame 3 to maintain the self-supporting composite panel 10 in position on the latter, before the establishment of the fasteners.

Pour garantir une parfaite étanchéité, des joints d'étanchéité 9 sont mis en place sur les éléments de charpente 3 avant la mise en place des panneaux composites autoportants 10, la couche écran de sous toiture 23 d'un élément 11 recouvre en partie le ou les éléments 11 adjacents, et l'espace entre ces derniers au droit du faitage est comblé par de la mousse expansive 41.To guarantee a perfect seal, gaskets 9 are put in place on the frame members 3 before the setting up of the self-supporting composite panels 10, the under-roof screen layer 23 of an element 11 partly covers the or the adjacent elements 11, and the space between them at the ridge is filled by expansive foam 41.

Avec une telle configuration, on comprend bien que les panneaux composites autoportants 10 permettent la pose d'une toiture 4 très rapide et la mise hors d'eau d'une maison d'habitation 1 en une seule opération tout en garantissant une parfaite étanchéité à l'eau et à l'air.With such a configuration, it is understood that the self-supporting composite panels 10 allow the installation of a roof 4 very fast and the out of water of a dwelling house 1 in a single operation while ensuring a perfect seal at water and air.

Enfin, on comprend bien que la conception des panneaux composites autoportants 10 permet de poser ces derniers sur la charpente 3 non seulement de manière à avoir les bords longitudinaux 15,16 de leur élément 11 perpendiculaires à l'axe longitudinal de la faitière 7, mais également de manière à avoir les bords longitudinaux 15,16 de leur élément 11 parallèles à l'axe longitudinal de la faitière 7.Finally, it is understood that the design of the self-supporting composite panels 10 makes it possible to place the latter on the frame 3 not only so as to have the longitudinal edges 15,16 of their element 11 perpendicular to the longitudinal axis of the ridge 7, but also so as to have the longitudinal edges 15,16 of their element 11 parallel to the longitudinal axis of the ridge 7.

Selon une variante de réalisation représentée à la figure 6, pour augmenter la résistance au feu du panneau composite autoportant et plus particulièrement de garantir le plus longtemps possible sa rigidité lorsqu'un feu se déclare au niveau de la toiture, chaque élément 11,11' comporte au moins une et de préférence plusieurs barres longitudinales de renfort 42 solidaires de la première couche de renfort 18,18' et disposées dans la couche isolante 19,19', lesdites barres longitudinales de renfort 42 s'étendant entre les bords latéraux dudit élément 11,11' parallèlement à ses bords longitudinaux 15,15';16,16'.According to an embodiment variant represented in figure 6 , to increase the fire resistance of the self-supporting composite panel and more particularly to guarantee as long as possible its rigidity when a fire is declared at the level of the roof, each element 11, 11 'comprises at least one and preferably several bars longitudinal reinforcement 42 integral with the first reinforcing layer 18, 18 'and disposed in the insulating layer 19, 19', said longitudinal reinforcement bars 42 extending between the lateral edges of said element 11, 11 'parallel to its longitudinal edges 15,15 ';16,16'.

Avec cette variante de réalisation, la rigidité de chaque élément 11,11' est garantie lorsque la couche isolante 19,19' se détériore suite à une élévation importante de température générée par un incendie au niveau de la toiture.With this variant embodiment, the rigidity of each element 11, 11 'is guaranteed when the insulating layer 19, 19' deteriorates as a result of a significant increase in temperature generated by a fire at the level of the roof.

Possibilité d'application industriellePossibility of industrial application
