Abstract

The device has a web (4) including a rigid insulating foam arranged between two rigid faces (2, 3). Longitudinal sides of panels are arranged for assembling the panels by an interlocking system which cooperates with the core and longitudinal folded edges (2a, 2b, 3a, 3b) of the rigid faces. A specific profile of the longitudinal sides of the panels is defined by a series of tabs (6-11) and notches (12-17) to assemble the panels together.

Description

-1- Dispositif de jonction par embrèvement de panneaux sandwich. La-1- Junction device by recessing sandwich panels. The

présente invention concerne un dispositif de jonction par embrèvement de panneaux sandwich avantageusement utilisables pour la couverture de locaux professionnels, de garages ou autres bâtiments de grandes dimensions. Ce dispositif est également applicable à la réalisation de couvertures de dimensions plus modestes telles que les couvertures de vérandas, de terrasses, de maisons individuelles, de balcons, de galerie, etc., ou à la réalisation de bardages ou analogues. to Plus généralement, l'invention est applicable à la réalisation de surfaces ou parois ayant des fonctions diverses les exposant au ruissellement, ces surfaces ou parois auxquelles il est fréquemment demandé d'offrir des qualités d'isolation thermique et phonique, pouvant être disposées horizontalement, avec une inclinaison plus ou moins prononcée, ou dressées verticalement. 15 Les panneaux composites utilisés pour la réalisation de ces surfaces ou parois peuvent être constituées d'une âme de mousse rigide de matière plastique disposée entre deux parements rigides. Pour la réalisation de couvertures de grandes dimensions, il est connu (EP-0 796 960) d'accoler de tels panneaux fixés sur une ossature porteuse, en 20 ménageant entre les panneaux un espace que l'on remplit ensuite avec une mousse de polyuréthane. Une bande de PVC est ensuite appliquée par collage ou soudage à chaud sur la zone de jonction des panneaux pour assurer l'étanchéité de cette jonction. L'inconvénient de ce mode de jonction est que les qualités de la bande de protection sont plus ou moins rapidement altérées du fait 25 de son exposition permanente à l'ensoleillement et aux intempéries, de sorte que l'étanchéité n'est plus assurée. Il est aussi connu, pour assurer l'étanchéité dans la zone de jonction des panneaux (EP-0 354 149) d'encastrer une gouttière de drainage dans une rainure ou saignée longitudinale ménagée symétriquement dans les chants de 30 l'âme de deux panneaux à structure sandwich accolés. Toutefois, il a été -2- constaté, à l'usage, que les panneaux ainsi assemblés présentaient une rigidité insuffisante dans de nombreuses applications et qu'un tel dispositif de jonction ne présentait pas des qualités d'étanchéité et de stabilité suffisamment fiables et durables dans le temps.  The present invention relates to a junction device by recess sandwich panels advantageously used for the coverage of professional premises, garages or other large buildings. This device is also applicable to the realization of more modest covers such as roofs of verandas, terraces, houses, balconies, gallery, etc., or the realization of cladding or the like. More generally, the invention is applicable to the production of surfaces or walls having various functions exposing them to runoff, these surfaces or walls which are frequently required to offer thermal and sound insulation qualities, which can be arranged horizontally , with a more or less pronounced inclination, or erected vertically. The composite panels used for producing these surfaces or walls may consist of a core of rigid plastic foam disposed between two rigid facings. For the production of large covers, it is known (EP-0 796 960) to join such panels fixed to a load-bearing framework, leaving between the panels a space which is then filled with a polyurethane foam. . A PVC strip is then applied by gluing or hot welding on the junction area of the panels to seal this junction. The disadvantage of this junction mode is that the qualities of the protective strip are more or less rapidly deteriorated due to its permanent exposure to sunlight and weather, so that the seal is no longer assured. It is also known, for sealing in the joint zone of the panels (EP-0 354 149), to embed a drainage trough in a longitudinal groove or groove arranged symmetrically in the edges of the core of two panels. sandwiched structure. However, it has been found, in use, that the panels thus assembled had insufficient rigidity in many applications and that such a joining device did not have sufficiently reliable sealing and stability qualities and lasting in time.

Pour pallier cet inconvénient, il a été prévu ( par exemple dans le document FR-2 710 374) d'incorporer, dans les cotés longitudinaux des panneaux à structure sandwich, des profilés rigides d'habillage de chant comportant une gorge longitudinale dont le fond est conformé pour constituer un canal de drainage, et d'encastrer dans les gorges longitudinales, une gouttière de ~o drainage disposée de manière que ses faces latérales aboutissent, respectivement, à l'ouverture d'entrées des dits canaux de drainage, ce qui permet d'améliorer l'étanchéité. Le dispositif a pour inconvénient d'être relativement coûteux en raison d'une fabrication relativement complexe des panneaux, tandis que le dispositif de jonction proposé n'apporte pas une 15 amélioration sensible des qualités de stabilité et de rigidité. D'autre part, on a déjà préconisé (WO-99/24682) de replier des parties latérales débordantes des parements rigides des panneaux, de sorte à créer des gorges latérales longitudinales permettant le logement d'éléments d'assemblage évitant la formation de ponts thermiques dans la zone de jonction des panneaux. 20 L'invention se propose d'apporter des solutions aux problèmes sus mentionnés non résolus par les procédés et systèmes de l'état de la technique et plus particulièrement aux problèmes de rigidité, de stabilité et d'étanchéité, grâce à son dispositif de liaison. Selon l'invention, ces problèmes sont résolus au moyen de panneaux 25 sandwich du genre composé d'une âme essentiellement constituée d'une mousse isolante rigide prise entre deux parements rigides de préférence constitués par des tôles d'acier et principalement remarquables en ce que les côtés longitudinaux desdits panneaux sont agencés pour permettre leur assemblage par un système d'emboîtement à double rainure et languette ou 30 embrèvement double auquel participent, à la fois, l'âme de mousse isolante rigide et les bords repliés des parements rigides. -3- Selon un mode d'exécution intéressant, les chants de l'âme de mousse isolante rigide des panneaux sont pourvus, dans la partie médiane de leurs épaisseurs, d'une rainure longitudinale, et le dispositif de jonction étanche selon l'invention comprend également une gouttière de jonction et de drainage destinée à être encastrée, par l'intermédiaire de ses bords opposés, dans les rainures de deux panneaux accolés. La mise en oeuvre du dispositif de l'invention autorise la réalisation de couvertures présentant une bonne résistance mécanique permettant d'envisager la construction de toitures de grandes surfaces. En outre, les panneaux sont ~o assemblés de manière étanche et la pérennité de cette étanchéité est bien assurée. Les buts, caractéristiques, et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et des dessins annexés dans lesquels : 15 - La figure 1 est une vue en coupe transversale d'un panneau suivant l'invention. La figure 2 est une vue en coupe transversale représentant la pièce de jonction de deux panneaux, servant de gouttière. - La figure 3 est une vue en coupe transversale représentant le profil des 20 côtés adjacents de deux panneaux et la gouttière de jonction avant emboîtage desdits panneaux. - La figure 4 est une vue en coupe transversale représentant la liaison de deux panneaux emboîtés. On se réfère aux dits dessins pour décrire un exemple intéressant, bien 25 que nullement limitatif, de réalisation du dispositif de jonction étanche selon l'invention. L'invention s'applique à l'assemblage de panneaux-sandwich 1 du type comprenant deux parements rigides 2 et 3 et une âme isolante 4 disposée entre ces parements. -4- Dans la description qui suit, l'un (2) des parements, appelé à être orienté en direction de l'extérieur de l'ouvrage en faisant application, sera appelé conventionnellement "parement externe", alors que l'autre (3) sera nommé "parement interne".  To overcome this drawback, it has been provided (for example in document FR-2 710 374) to incorporate, in the longitudinal sides of the sandwich structure panels, rigid profiles for edge dressing having a longitudinal groove whose bottom is formed to form a drainage channel, and to embed in the longitudinal grooves, a ~ o drain drainage arranged so that its side faces end, respectively, to the opening of entries of said drainage channels, which improves the seal. The disadvantage of the device is that it is relatively expensive because of the relatively complex manufacture of the panels, while the proposed jointing device does not provide a significant improvement in the qualities of stability and rigidity. On the other hand, it has already been advocated (WO-99/24682) to fold up flanking side portions of the rigid facings of the panels, so as to create longitudinal lateral grooves for housing assembly elements avoiding the formation of bridges in the area where the panels meet. The invention proposes to provide solutions to the aforementioned problems not solved by the methods and systems of the state of the art and more particularly to the problems of rigidity, stability and sealing, thanks to its connecting device. . According to the invention, these problems are solved by means of sandwich panels of the kind consisting of a core consisting essentially of a rigid insulating foam sandwiched between two rigid facings, preferably consisting of steel sheets and mainly remarkable in that the longitudinal sides of said panels are arranged to allow their assembly by a double groove and tongue or double recess interlocking system in which both the rigid insulating foam core and the folded edges of the rigid facings participate. According to an interesting embodiment, the edges of the insulating rigid foam core of the panels are provided, in the middle part of their thicknesses, with a longitudinal groove, and the sealed jointing device according to the invention. also comprises a junction and drainage trough intended to be recessed, via its opposite edges, into the grooves of two adjoining panels. The implementation of the device of the invention allows the realization of covers having good mechanical strength to consider the construction of roofs large areas. In addition, the panels are ~ o tightly assembled and the durability of this seal is ensured. The above and other objects, features, and advantages will become more apparent from the following description and accompanying drawings, in which: FIG. 1 is a cross-sectional view of a panel according to the invention; . Figure 2 is a cross-sectional view showing the joining part of two panels, serving as a gutter. FIG. 3 is a cross-sectional view showing the profile of the adjacent sides of two panels and the junction groove before fitting of said panels. - Figure 4 is a cross-sectional view showing the connection of two nested panels. Reference is made to the said drawings to describe an interesting example, although not limiting, of the embodiment of the sealed junction device according to the invention. The invention applies to the assembly of sandwich panels 1 of the type comprising two rigid facings 2 and 3 and an insulating core 4 disposed between these facings. In the following description, one (2) of the facings, which is to be oriented toward the outside of the structure by application, will be conventionally called "external facing", while the other ( 3) will be named "internal facing".

Selon les applications envisagées, les parements rigides 2 et 3 peuvent être constitués par des tôles d'acier galvanisées, ou laquées, ou par des tôles d'aluminium laquées ou autrement traitées, voire par des plaques de matière plastique rigide, lesdits parements pouvant par ailleurs être recouverts de tout autre revêtement de nature et coloris appropriés à l'usage des panneaux.  Depending on the applications envisaged, rigid facings 2 and 3 may consist of galvanized or lacquered steel sheets, or of lacquered or otherwise treated aluminum sheets, or even of rigid plastic plates, said facings being able to in addition, be covered with any other covering of nature and colors appropriate to the use of the panels.

L'âme 4 est essentiellement constituée par une mousse rigide de matière plastique telle que mousse de polyuréthanne, mousse de chlorure de polyvinyle, mousse de polystyrène extrudé, etc. Selon une disposition caractéristique de l'invention, au moins les côtés ou chants longitudinaux des panneaux 1 sont agencés pour permettre leur assemblage par un système d'emboîtement à double rainure et languette ou embrèvement double, auquel participent, à la fois, l'âme de mousse isolante rigide 4 et les bords longitudinaux repliés 2a, 2b et 3a, 3b, des parements 2 et 3, respectivement. De la sorte, on conçoit que les bords repliés 2a, 2b et 3a, 3b des parements 2 et 3 contribuent à la rigidité des panneaux et à la rigidification des couvertures constituées d'une pluralité de panneaux 1A, 1B, ..., accolés les uns aux autres. Le profil spécifique des côtés longitudinaux des panneaux est défini par une série de languettes 6, 7, 8 et 9, 10, 11 et de rainures ou entailles 12, 13, 14 et 15, 16, 17, réalisées sur toute la longueur des chants des panneaux 1, permettant d'assembler lesdits panneaux entre eux, par embrèvement. Les languettes 7 et 10 sont réalisées dans le matériau constituant l'âme 4 du panneau 1 et les languettes 6 et 9, sont constituées par un pliage (2a, 3b) de l'un des bords longitudinaux des parements externe 2 et interne 3, respectivement. D'autre part, les languettes 8 et 11 sont constituées par une partie saillante de l'âme de mousse rigide 4 recouverte, sur deux de ses trois faces, par l'un des bords longitudinaux replié 3a, 2b des parements interne 3 et -5- externe 2, respectivement. Ces bords repliés 6, 9 et 8, 11, renforcent la rigidité des panneaux et de leur assemblage. L'une des entailles 14, 17 de chaque côté longitudinal ou chant des panneaux, est constituée par l'un des bords longitudinaux replié 3a, 2b du parement interne 3 et du parement externe 2, respectivement, desdits panneaux. Les languettes 6 et 9 constituées par les bords repliés 2a, 3b des parements 2 et 3 et les entailles 14 et 17 formées par les bords repliés 3a, 2b desdits parements, sont disposées de sorte que lors de l'assemblage des panneaux 1A, 1B, lesdites languettes renforcées 6 et 9 se trouvent engagées dans lesdites entailles renforcées 17 et 14. Selon le mode d'exécution illustré, les chants opposés de l'âme 4 de mousse isolante rigide, sont pourvus, dans la partie médiane de leur épaisseur et sur toute leur longueur, d'une rainure longitudinale 5, 5a et le dispositif d'emboîtement étanche selon l'invention comprend également une gouttière de jonction et de drainage 18 destinée à être encastrée, par l'intermédiaire de ses parties latérales opposées, dans les rainures 5, 5a de deux panneaux 1A et 1B accolés. Cette gouttière 18 est, de préférence, réalisée dans un matériau ferreux traité contre la corrosion, par exemple en acier galvanisé. Elle contribue à l'assemblage, à l'étanchéité et à la stabilité de la liaison de deux panneaux accolés 1A et I B. Les figures 3 et 4 illustrent l'assemblage par embrèvement de deux panneaux 1A et 1B selon l'invention. Lors de l'accolement des panneaux, les languettes 9, 10 et 11 du panneau 1B s'encastrent dans les rainures ou entailles 14, 13, 12 du panneau 1A, respectivement, tandis que les languettes 8, 7, 6 de ce dernier s'encastrent dans les rainures ou entailles 15, 16, 17, respectivement, du panneau I B. -6- Des joints 19 et 20 sont positionnés dans les interstices de la liaison, par embrèvement pour garantir une isolation étanche de la paroi constituée par un ensemble de panneaux. Le joint 19, côté face intérieure, servant à réaliser une finition correcte de la 5 paroi est constitué par un matériau souple et facilement applicable en cordon, tels que par exemple un joint en silicone. Selon l'emboîtement représenté par les languettes 9, 10, 11, d'une part, et 6, 7, 8, d'autre part, sont placés dans les interstices de la liaison, deux joints 20 positionnés pour réaliser une isolation étanche de l'emboîtement de deux 10 panneau 1A et 1B. Les joints 20 servant à réaliser une étanchéité idéale de la liaison entre deux panneaux 1A et 1B sont constitués par un matériau autocollant, tels que par exemple un joint en mastic butyl, durcissable après l'application sur le chant du panneau et après l'emboîtage du dispositif selon l'invention.  The core 4 is essentially constituted by a rigid plastic foam such as polyurethane foam, polyvinyl chloride foam, extruded polystyrene foam, etc. According to a characteristic arrangement of the invention, at least the sides or longitudinal edges of the panels 1 are arranged to allow their assembly by a double groove and tongue or double recess interlocking system, in which both the core rigid insulating foam 4 and the folded longitudinal edges 2a, 2b and 3a, 3b, facings 2 and 3, respectively. In this way, it can be seen that the folded edges 2a, 2b and 3a, 3b of the facings 2 and 3 contribute to the rigidity of the panels and to the stiffening of the covers consisting of a plurality of panels 1A, 1B, ..., contiguous each other. The specific profile of the longitudinal sides of the panels is defined by a series of tongues 6, 7, 8 and 9, 10, 11 and grooves or notches 12, 13, 14 and 15, 16, 17, made along the entire length of the edges. panels 1, for assembling said panels together, by recess. The tongues 7 and 10 are made of the material constituting the core 4 of the panel 1 and the tongues 6 and 9 consist of a folding (2a, 3b) of one of the longitudinal edges of the outer and inner plies 2 and 3, respectively. On the other hand, the tongues 8 and 11 are constituted by a projecting portion of the rigid foam core 4 covered, on two of its three faces, by one of the folded longitudinal edges 3a, 2b of the internal facings 3 and - 5- external 2, respectively. These folded edges 6, 9 and 8, 11, reinforce the rigidity of the panels and their assembly. One of the notches 14, 17 on each longitudinal side or edge of the panels, is constituted by one of the folded longitudinal edges 3a, 2b of the inner facing 3 and the outer facing 2, respectively, of said panels. The tongues 6 and 9 constituted by the folded edges 2a, 3b of the facings 2 and 3 and the notches 14 and 17 formed by the folded edges 3a, 2b of said facings, are arranged so that during the assembly of the panels 1A, 1B said reinforced tongues 6 and 9 are engaged in said reinforced notches 17 and 14. According to the illustrated embodiment, the opposite edges of the core 4 of rigid insulating foam, are provided in the middle part of their thickness and along their entire length, a longitudinal groove 5, 5a and the tight fitting device according to the invention also comprises a junction and drainage trough 18 intended to be recessed, via its opposite lateral parts, in the grooves 5, 5a of two panels 1A and 1B contiguous. This channel 18 is preferably made of a ferrous material treated against corrosion, for example galvanized steel. It contributes to the assembly, sealing and stability of the connection of two contiguous panels 1A and 1B. FIGS. 3 and 4 illustrate the assembly by recessing of two panels 1A and 1B according to the invention. When joining the panels, the tabs 9, 10 and 11 of the panel 1B are embedded in the grooves or notches 14, 13, 12 of the panel 1A, respectively, while the tabs 8, 7, 6 of the latter embedded in the grooves or notches 15, 16, 17, respectively, of the panel I B. -6- Seals 19 and 20 are positioned in the interstices of the connection, by recess to ensure a tight insulation of the wall constituted by a set of panels. The gasket 19, on the inner side, used to achieve a correct finish of the wall is constituted by a flexible material and easily applicable in bead, such as for example a silicone gasket. According to the interlocking represented by the tabs 9, 10, 11, on the one hand, and 6, 7, 8, on the other hand, are placed in the interstices of the connection, two seals 20 positioned to achieve a watertight insulation of the interlocking of two panels 1A and 1B.
