Description

La présente invention concerne des panneaux intérieurs de façades légères ventilées de bâtiments comportant des baies.The present invention relates to interior panels of light ventilated facades of buildings comprising bays.

Dans l'industrie du bâtiment, des façades légères ventilées sont bien connues. Elles sont appréciées pour leurs excellentes performances techniques, en particulier en ce qui concerne l'isolation thermique, la grande variété de choix des parements extérieurs et leur amovibilité facile. Les parements extérieurs peuvent, en effet, être enlevés et remplacés rapidement et proprement, totalement ou partiellement, et cela à peu de frais, sans affecter l'utilisation des bâtiments et sans gêner leurs occupants.In the building industry, ventilated light facades are well known. They are appreciated for their excellent technical performance, in particular with regard to thermal insulation, the wide variety of choice of exterior cladding and their easy removal. Exterior facings can, in fact, be removed and replaced quickly and cleanly, totally or partially, and at low cost, without affecting the use of the buildings and without disturbing their occupants.

C'est à des constructions traditionnelles lourdes que l'on voit le plus souvent appliquer la technique des façades légères ventilées. Dans ce cas, la paroi intérieure est généralement un mur de maçonnerie ou un voile de béton armé.It is to heavy traditional constructions that we most often see applying the technique of light ventilated facades. In this case, the interior wall is generally a masonry wall or a reinforced concrete veil.

Dans la construction industrialisée légère, il est connu de fabriquer la paroi intérieure de façade en usine et de la fixer à l'ossature du bâtiment. Une lame d'air ventilée est ménagée entre cette paroi intérieure et un bardage ou parement extérieur qui, par divers moyens, est fixé devant la paroi intérieure. C'est principalement pour la réalisation de parties opaques de façades (ou de façades entièrement opaques) que de tels systèmes présentent de réels avantages.In light industrialized construction, it is known to manufacture the interior facade wall in the factory and to fix it to the frame of the building. A ventilated air space is provided between this interior wall and an exterior cladding or facing which, by various means, is fixed in front of the interior wall. It is mainly for the production of opaque parts of facades (or fully opaque facades) that such systems have real advantages.

Cependant, lorsqu'il s'agit de construire une façade légère ventilée qui doit comporter des baies pour fenêtres, porte-fenêtres, etc., ce qui est quasiment toujours le cas, la fabrication et l'assemblage de cette façade deviennent plus compliqués, coûteux et peu systématiques, surtout lorsqu'il faut prévoir des baies de dimensions diverses.However, when it comes to building a light ventilated facade which must include windows, windows, French windows, etc., which is almost always the case, the manufacture and assembly of this facade becomes more complicated, expensive and not very systematic, especially when it is necessary to provide bays of various dimensions.

La présente invention a pour but de fournir des panneaux intérieurs de façades légères ventilées qui soient eux-mêmes légers et dont la construction procure un encadrement de baie simple et peu coûteux comme c'est le cas dans la construction de façades légères ventilées dont la paroi intérieure est lourde, en maçonnerie ou en béton armé.The present invention aims to provide interior panels of ventilated light facades which are themselves light and whose construction provides a simple and inexpensive bay frame as is the case in the construction of ventilated light facades whose wall interior is heavy, in masonry or reinforced concrete.

Un autre but de l'invention est de permettre la construction systématique, facile et économique de baies de dimensions très différentes.Another object of the invention is to allow the systematic, easy and economical construction of bays of very different dimensions.

Un autre but de l'invention est de permettre la combinaison d'un panneau intérieur avec fenêtre, qui résiste à la corrosion par les agents atmosphériques, qui soit mécaniquement résistant et qui puisse éventuellement comporter un dormant de chassis incorporé dans le panneau intérieur.Another object of the invention is to allow the combination of an interior panel with window, which resists corrosion by atmospheric agents, which is mechanically resistant and which may optionally include a frame frame incorporated in the interior panel.

Un autre but est de fournir une paroi intérieure légère, facile à pourvoir de moyens d'isolation thermique, ne présentant pas elle-même de pont thermique, offrant par elle-même une étanchéité à la fois à l'eau et à la vapeur d'eau et permettant la réalisation facile de la lame d'air ventilée.Another object is to provide a light interior wall, easy to provide with means of thermal insulation, not itself presenting a thermal bridge, offering by itself a seal both at water and at vapor. water and allowing easy realization of the ventilated air knife.

Un autre but est de faciliter, simplifier, rationaliser et rendre modulaire la fabrication et l'assemblage de la paroi intérieure et son montage sur l'ossature.Another object is to facilitate, simplify, rationalize and make modular the manufacture and assembly of the interior wall and its mounting on the framework.

Un autre but de l'invention est de rendre les façades légères ventilées encore plus facilement démontables et interchangeables, partiellement ou totalement, que ne le sont les façades légères connues.Another object of the invention is to make ventilated light facades even more easily removable and interchangeable, partially or totally, than are the known light facades.

La présente invention a pour objet un panneau intérieur de façade légère ventilée pourvu d'au moins une baie. Ce panneau intérieur comporte des profilés verticaux en forme de C stylisé ayant un pan central dorsal auquel se raccordent, à angle droit, deux pans latéraux portant eux-­mêmes un rebord à angle droit, les deux rebords étant dirigés l'un vers l'autre. Ces profilés verticaux, juxtaposés et assemblés les uns aux autres par leurs pans latéraux, sont interrompus à l'endroit de la baie. Le panneau intérieur ainsi formé est renforcé par des profilés raidisseurs fixés le long des bords horizontaux du panneau intérieur et de la baie. La suite des pans dorsaux des profilés verticaux forme une feuille dorsale continue destinée à être fixée à l'ossature d'un bâtiment. Les rebords des profilés verticaux en C sont destinés à porter un parement extérieur de la façade légère ventilée.The present invention relates to an interior panel of ventilated light facade provided with at least one opening. This interior panel has stylized vertical C-shaped profiles having a central back panel to which are connected, at right angles, two side panels themselves carrying a rim at right angles, the two rims being directed towards each other. . These vertical profiles, juxtaposed and assembled to each other by their side panels, are interrupted at the location of the bay. The interior panel thus formed is reinforced by stiffening profiles fixed along the horizontal edges of the interior panel and of the opening. The series of dorsal sections of the vertical profiles forms a continuous dorsal sheet intended to be fixed to the framework of a building. The edges of the vertical C profiles are intended to carry an exterior facing of the ventilated light facade.

Suivant une forme d'exécution avantageuse, le panneau intérieur comporte, des profilés verticaux dont les pans dorsaux sont de largeurs différentes, par exemple de 30, 45 et 60 cm. La juxtaposition appropriée de profilés de largeurs différentes permet ainsi la réalisation de panneaux de dimensions diverses pourvus eux-mêmes de baies de la largeur désirée, laquelle peut différer d'un panneau à l'autre. La hauteur de la baie est définie par un simple choix de la longueur des profilés, selon la hauteur requise au-dessus et au-dessous de la baie pour le linteau et pour l'allège. On peut ainsi réaliser des panneaux et des baies de dimensions variées sans qu'il n'y ait jamais aucune perte de matière, ce qui est économiquement très important.According to an advantageous embodiment, the inner panel comprises, vertical profiles whose back panels are of different widths, for example 30, 45 and 60 cm. The appropriate juxtaposition of profiles of different widths thus allows the production of panels of various dimensions themselves provided with bays of the desired width, which may differ from one panel to another. The height of the opening is defined by a simple choice of the length of the profiles, depending on the height required above and below the opening for the lintel and for the sill. It is thus possible to produce panels and bays of various dimensions without there ever being any loss of material, which is economically very important.

Les profilés utilisés peuvent être faits en divers matériaux et notamment en métal.The profiles used can be made of various materials including metal.

Toutefois, ces profilés sont de préférence en matériau composite comportant des polymères et des matériaux de renfort. Ce choix de matériau permet de réaliser des panneaux intérieurs qui sont légers tout en étant mécaniquement résistants, et permet également d'éviter les ponts thermiques entre l'extérieur et l'intérieur du bâtiment. En outre, les profilés en matériau composite peuvent facilement être assemblés entre eux, notamment par collage.However, these profiles are preferably made of composite material comprising polymers and reinforcing materials. This choice of material makes it possible to produce interior panels which are light while being mechanically resistant, and also makes it possible to avoid thermal bridges between the exterior and the interior of the building. In addition, the profiles of composite material can easily be assembled together, in particular by gluing.

Les polymères peuvent être choisis parmi une gamme très large de matières plastiques, comme par exemple les polyesters insaturés, le poly(chlorure de vinyle), les polyimide et les polycarbonate. Les matériaux de renfort peuvent également être de nature diverses. Ce sont, en général, des fibres, par exemple les fibres de verre ou de carbone.The polymers can be chosen from a very wide range of plastics, such as, for example, unsaturated polyesters, poly (vinyl chloride), polyimide and polycarbonate. The reinforcing materials can also be of various kinds. These are, in general, fibers, for example glass or carbon fibers.

Suivant une forme préférée d'exécution, lre profilés en C, en matière plastique renforcée, sont fabriqués par pultrusion.According to a preferred embodiment, the first C profiles, made of reinforced plastic, are produced by pultrusion.

Les profilés verticaux en C présentent, de préférence, une surépaisseur à l'endroit de leurs rebords et à la partie du pan dorsal située en regard. Lorsque des profilés verticaux sont juxtaposés et assemblés entre eux pour former un panneau intérieur, ces parties en surépaisseur, dont l'inertie est ainsi augmentée, forment avec les pans latéraux des profils renforcés en I qui permettent au panneau intérieur de mieux résister aux sollicitations dynamique de pression et de dépression engendrées par le vent et aux sollicitations statiques engendrées par le poids plus ou moins important des parements extérieurs.The vertical C-shaped profiles preferably have an extra thickness at the point of their edges and at the part of the back panel situated opposite. When vertical profiles are juxtaposed and joined together to form an interior panel, these extra parts, the inertia of which is thus increased, form with the lateral sections profiles reinforced in I which allow the interior panel to better withstand dynamic stresses of pressure and depression generated by the wind and the static stresses generated by the more or less significant weight of the exterior facings.

Suivant une forme d'exécution préférée, une couche de matériau isolant couvre le pan central dorsal à l'intérieur de chaque profilé vertical en C. L'épaissuer de cette couche d'isolant est moindre que la largeur des pans latéraux, de manière à ménager un espace constituant une lame d'air de ventilation verticale entre la couche d'isolant et le parement extérieur qui sera fixé devant le panneau intérieur.According to a preferred embodiment, a layer of insulating material covers the central back panel inside each vertical section in C. The thickness of this insulating layer is less than the width of the side panels, so as to create a space constituting a vertical air gap between the insulation layer and the exterior facing which will be fixed in front of the interior panel.

Suivant une forme exécution particulière, les pans latéraux des profilés verticaux en C présentent une nervure dirigée vers l'intérieur du C. Ces nervures maintiennent en place, devant la couche de matériau isolant, une feuille flexible en un matériau différent de celui de la couche d'isolant, par exemple une tôle d'aluminium, en améliorant ainsi l'isolation acoustique.According to a particular embodiment, the lateral sections of the vertical profiles in C have a rib directed towards the interior of the C. These ribs hold in place, in front of the layer of insulating material, a flexible sheet of a material different from that of the layer insulation, for example an aluminum sheet, thereby improving the sound insulation.

Suivant une autre forme d'exécution particulière, le pan central dorsal des profilés verticaux en C est formé de deux ou plusieurs feuilles parallèles reliées entre elles par les pans latéraux. L'espace ménagé entre ces feuilles parallèles est rempli d'un matériau isolant acoustique et thermique, par exemple une mousse polymère ou de la laine de roche.According to another particular embodiment, the central back panel of the vertical C-shaped sections is formed two or more parallel sheets joined together by the side panels. The space provided between these parallel sheets is filled with an acoustic and thermal insulating material, for example a polymer foam or rock wool.

Ces feuilles parallèles qui forment le pan dorsal des profilés verticaux en C peuvent éventuellement toutes faire partie intégrante du profilé (qui est, de préférence, pultrudé). Il est cependant prévu également que seule la feuille située le plus en arrière fasse partie intégrante du profilé vertical en C, la feuille (ou les feuilles) située(s) plus en avant étant glissée(s) en place entre les pans latéraux, dans de petites glissières prévues à cet effet. Dans ce cas, il est avantageux de réaliser cette feuille (ou ces feuilles) en une matière différente de celle du profilé lui-même, de manière à améliorer l'isolation acoustique.These parallel sheets which form the dorsal side of the vertical C-shaped profiles may possibly all be an integral part of the profile (which is preferably pultruded). However, it is also intended that only the sheet located furthest back forms an integral part of the vertical section in C, the sheet (or sheets) located (s) further forward being slid (s) in place between the side panels, in small slides provided for this purpose. In this case, it is advantageous to produce this sheet (or these sheets) in a material different from that of the profile itself, so as to improve the sound insulation.

Lorsque le pan central dorsal des profilés verticaux en C est formé de plus de deux feuilles parallèles (par exemple trois feuilles), les espaces entre les feuilles successives peuvent être remplis de matériaux isolants différents, ce qui améliore encore l'isolation acoustique.When the central dorsal section of the vertical C-shaped sections is formed from more than two parallel sheets (for example three sheets), the spaces between the successive sheets can be filled with different insulating materials, which further improves the sound insulation.

Suivant une forme d'exécution particulière, le panneau intérieur comporte, en outre, des profilés en forme de T, en matériau composite pultrudé, fixés verticalement contre sa face dorsale aux endroits de jonction des profilés verticaux en C, renforçant ainsi la liaison entre ces profilés verticaux. Une feuille ou plaque mince (par exemple une tôle ou une plaque mince en fibres-ciment) peut être fixée contre ces profilés en T, parallèlement aux pans dorsaux des profilés verticaux en C. L'espace entre cette feuille ou plaque et lesdits pans dorsaux peut être rempli d'un matériau isolant acoustique et thermique.According to a particular embodiment, the interior panel further comprises T-shaped profiles, of pultruded composite material, fixed vertically against its dorsal face at the junction points of the vertical C-shaped profiles, thus strengthening the connection between these vertical profiles. A thin sheet or plate (for example a sheet or a thin fiber-cement plate) can be fixed against these T-profiles, parallel to the back panels of the vertical C profiles. The space between this sheet or plate and said back panels can be filled with an acoustic and thermal insulating material.

A l'endroit de la baie, les pans latéraux des profilés verticaux en C ainsi que les profilés raidisseurs peuvent être munis de pans dirigés vers l'intérieur de la baie, formant un motif en F. L'ensemble de ces motifs en F forme un dormant de fenêtre à double battée.At the location of the opening, the lateral sections of the vertical C-shaped sections as well as the stiffening sections may be provided with sections facing the inside of the bay, forming a pattern in F. All of these patterns in F form a double window sash.

Les profilés raidisseurs fixés le long des bords horizontaux du panneau intérieur et de la baie sont, de préférence, faits de matériau composite et formés par pultrusion. Ce sont, de préférence, des profilés en caisson et l'espace compris dans ces profilés peut être rempli d'une matière isolante thermique et acoustique.The stiffening profiles fixed along the horizontal edges of the interior panel and the opening are preferably made of composite material and formed by pultrusion. They are preferably box profiles and the space included in these profiles can be filled with a thermal and acoustic insulating material.

Le profilé horizontal inférieur de la baie peut être prolongé d'un seuil de fenêtre.The lower horizontal profile of the opening can be extended by a window sill.

De manière avantageuse, le panneau intérieur comporte, en outre, des profilés porteurs horizontaux fixés contre les rebords des profilés verticaux en C et destinés à y accrocher des éléments de parement extérieur de la façade légère ventilée.Advantageously, the interior panel further comprises horizontal load-bearing profiles fixed against the edges of the vertical C-shaped profiles and intended to hang there elements of external facing of the light ventilated facade.

La présente invention a également pour objet une façade légère ventilée qui comporte des panneaux intérieurs tels que définis ci-dessus.The present invention also relates to a light ventilated facade which comprises interior panels as defined above.

Dans cette façade légère ventilée suivant l'invention, la jonction entre les panneaux intérieurs peut être faite au moyen de profilés en U en une matière souple et étanche, ces profilés en U s'appuyant contre des battées plates fixées aux bords arrière des panneaux intérieurs. L'espace compris entre ces profilés en U est rempli d'une matière isolante thermique et acoustique.In this light ventilated facade according to the invention, the junction between the interior panels can be made by means of U-shaped profiles made of a flexible and waterproof material, these U-shaped profiles pressing against flat beats fixed to the rear edges of the interior panels. . The space between these U-shaped profiles is filled with thermal and acoustic insulating material.

De manière particulière, l'invention a pour objet une façade légère ventilée qui comporte des panneaux intérieurs tels que définis ci-dessus, munis de profilés porteurs horizontaux auxquels sont fixés des éléments de parement extérieurs.In particular, the invention relates to a light ventilated facade which includes interior panels as defined above, provided with horizontal support profiles to which are attached exterior facing elements.

L'invention a également pour objet un procédé de construction d'un panneau intérieur d'une façade légère ventilée pourvu d'au moins une baie. Suivant ce procédé, on fabrique des profilés en forme de C stylisé, lesquels profilés ont un pan central dorsal auquel se raccordent, à angle droit, deux pans latéraux portant eux-mêmes un rebord à angle droit, les deux rebords étant dirigés l'un vers l'autre. On juxtapose de tels profilés en C de même longueur et à l'endroit prévu pour une baie, on intercale des profilés en C plus courts qui encadrent la baie par-dessus et par-dessous. On assemble tous les profilés en C entre eux, pan latéral contre pan latéral, tous les pans dorsaux de ces profilés étant disposés suivant un même plan. On fixe alors aux bords supérieur et inférieur des panneaux, ainsi qu'aux bords supérieur et inférieur de la baie, des profilés raidisseurs.The invention also relates to a method of constructing an interior panel of a ventilated light facade provided with at least one opening. According to this process, stylized C-shaped profiles are manufactured, which profiles have a central dorsal panel to which are connected, at right angles, two lateral panels themselves carrying a flange at right angles, the two edges being directed towards each other. Such C-profiles of the same length are juxtaposed and at the place provided for a bay, shorter C-sections are inserted which frame the bay above and below. All the C sections are assembled together, side panel against side panel, all the back panels of these sections being arranged in the same plane. Stiffeners are then fixed to the upper and lower edges of the panels, as well as to the upper and lower edges of the opening.

Les profilés en C sont avantageusement fabriqués par pultrusion d'un matériau composite.The C profiles are advantageously produced by pultrusion of a composite material.

Suivant une forme d'exécution préférée de ce procédé, on couvre le pan central dorsal à l'intérieur de chaque profilé en C d'une couche de matériau isolant, dont l'épaisseur est moindre que la largeur des pans latéraux.According to a preferred embodiment of this method, the central back panel is covered inside each C-shaped section with a layer of insulating material, the thickness of which is less than the width of the side panels.

Perpendiculairement à la direction des profilés en C, on peut fixer, contre les rebords de ceux-ci, des profilés porteurs destinés à y accrocher le parement extérieur de la façade légère ventilée.Perpendicular to the direction of the C profiles, it is possible to fix, against the edges of these, load-bearing profiles intended to hang the external facing of the light ventilated facade there.

Suivant une forme d'exécution particulière du procédé, on fixe des profilés en forme de T contre la face dorsale du panneau intérieur, parallèlement à la direction des profilés en C et aux endroits de leur jonction, renforçant la liaison entre eux; on remplit l'espace entre les profilés en T successifs d'un matériau isolant acoustique et thermique et on fixe une feuille contre les profilés en T.According to a particular embodiment of the method, T-shaped profiles are fixed against the dorsal face of the interior panel, parallel to the direction of the C profiles and at the places of their junction, strengthening the connection between them; the space between the successive T-profiles is filled with an acoustic and thermal insulating material and a sheet is fixed against the T-profiles.

Les panneaux intérieurs conformes à l'invention présentent de nombreux avantages.The interior panels according to the invention have many advantages.

Ils sont construits à partir d'un petit nombre de pièces de base, faciles à fabriquer et à assembler en atelier, avec un minimum de main-d'oeuvre.They are built from a small number of basic parts, easy to manufacture and assemble in the workshop, with a minimum of manpower.

Comme les profilés qui les composent sont faits de matériau composite, ils ont à la fois un poids faible, une bonne résistance mécanique et une faible conductivité thermique. L'épaisseur des profilés verticaux varie en fonction des sollicitations dynamiques et statiques auxquelles ses diverses parties sont soumises, ce qui permet d'allier un maximum de stabilité à un minimum de matière utilisée.As the profiles which compose them are made of composite material, they have at the same time a low weight, a good mechanical resistance and a low conductivity thermal. The thickness of the vertical profiles varies according to the dynamic and static stresses to which its various parts are subjected, which allows to combine maximum stability with a minimum of material used.

La forme des profilés verticaux assure une bonne rigidité du panneau intérieur dans le sens vertical. La rigidité du panneau dans le sens horizontal est assurée non seulement par les profilés raidisseurs horizontaux mais également par le fait que le panneau est fixé en plusieurs points à des éléments horizontaux de l'ossature du bâtiment.The shape of the vertical profiles ensures good rigidity of the interior panel in the vertical direction. The rigidity of the panel in the horizontal direction is ensured not only by the horizontal stiffening profiles but also by the fact that the panel is fixed at several points to horizontal elements of the frame of the building.

Des fenêtres fixes ou ouvrantes, avec ou sans dormant, peuvent être incorporées au panneau en atelier.Fixed or opening windows, with or without window frames, can be incorporated into the panel in the workshop.

Les panneaux sont étanches à la pluie, au vent et à la vapeur d'eau et permettent des degrés variables de sophistication des isolations thermique et phonique.The panels are waterproof against rain, wind and water vapor and allow varying degrees of sophistication in thermal and sound insulation.

La fabrication des panneaux intérieurs séparément du parement extérieur permet le montage de parements extérieurs très divers en nature, forme, relief et dimensions, même dans les façades d'un même bâtiment. Il peut s'agir de pierres minces, de marbres, de granits, de céramiques, de tôles d'aluminium ou d'acier, de matières plastiques, de plaques de fibres-ciment, etc. Le montage de ces parements sur le panneau intérieur peut éventuellement être réalisé en atelier.The manufacture of the interior panels separately from the exterior facing allows the mounting of exterior facing very diverse in nature, shape, relief and dimensions, even in the facades of the same building. It can be thin stones, marbles, granites, ceramics, aluminum or steel sheets, plastics, fiber cement sheets, etc. The mounting of these facings on the interior panel can possibly be carried out in the workshop.

Dans la technique des façades légères ventilées, les panneaux intérieurs suivant l'invention remplacent très avantageusement la paroi intérieure qui dans la construction traditionnelle lourde consiste généralement en un mur de maçonnerie ou un voile de béton armé.In the technique of light ventilated facades, the interior panels according to the invention very advantageously replace the interior wall which in traditional heavy construction generally consists of a masonry wall or a reinforced concrete veil.

De manière plus particulière, les éléments préfabriqués suivant l'invention peuvent être utilisés très avantageusement pour la réalisation de façades légères ventilées pour des bâtiments dont le gros oeuvre est construit au moyen d'unités de construction modulaires, et notamment pour des bâtiments dont le gros oeuvre est réalisé suivant la technique décrite dans le brevet européen n° 0 012 736.More particularly, the prefabricated elements according to the invention can be used very advantageously for the production of ventilated light facades for buildings whose main structure is constructed by means of modular construction units, and in particular for buildings whose large work is done according to the technique described in European patent No. 0 012 736.

Dans ce cas, les panneaux intérieurs suivant l'invention peuvent être montés, en atelier, sur les unités de construction modulaires. Le cas échéant, on peut fixer aux panneaux intérieurs des profilés porteurs horizontaux et éventuellement le parement extérieur.In this case, the interior panels according to the invention can be mounted, in the workshop, on modular construction units. If necessary, horizontal load-bearing profiles and possibly the exterior facing can be attached to the interior panels.

Dans ce cas encore, la face de la paroi intérieure tournée vers l'intérieur du bâtiment peut être dissimulée par une autre paroi, analogue aux cloisons intérieures du bâtiment, ce qui rend sans importance l'aspect de la face dorsale de la paroi intérieure et est de nature à renforcer encore davantage l'isolation acoustique et thermique des façades.In this case also, the face of the interior wall facing the interior of the building can be concealed by another wall, similar to the interior partitions of the building, which makes the appearance of the dorsal face of the interior wall irrelevant and is likely to further strengthen the acoustic and thermal insulation of facades.

On comprendra néanmoins que, dans le cadre de la présente invention, l'intérêt des façades légères ventilées comportant des baies n'est nullement limité à cette application sur des unités de construction modulaires.It will nevertheless be understood that, in the context of the present invention, the advantage of ventilated light facades comprising openings is in no way limited to this application on modular construction units.

Dans tous les cas on laisse un espace entre les bords des panneaux intérieurs. Pour réaliser un ajustage fin sur chantier, on peut exécuter la jonction entre panneaux et l'étanchéité du parement intérieur comme suit.In all cases, a space is left between the edges of the interior panels. To make a fine adjustment on site, the junction between panels and the sealing of the interior facing can be carried out as follows.

On fixe aux bords arrière des panneaux intérieurs des plats en aluminium ou en matière plastique renforcée qui servent de battées à la fermeture du joint. On fixe à ces battées, par collage ou vissage, des profilés en U en une matière souple mais étanche et on remplit l'espace compris dans ces profilés en U d'une matière isolante thermique.Aluminum or reinforced plastic dishes are fixed to the rear edges of the interior panels, which serve to beat the seal. U-shaped sections of flexible but impervious material are fixed to these ends by gluing or screwing, and the space comprised in these U-shaped sections is filled with thermal insulating material.

Fig. 2 is a horizontal section and FIG. 3 is a vertical section through part of the facade shown in FIG. 1.

Sur les Fig. 1 à 3, une ossature lourde 1 en béton armé porte un remplissage 2 en béton armé ou maçonnerie qui forme une paroi intérieure lourde comportant des baies 3. Sur la face extérieure de la paroi intérieure et de l'ossature sont fixés des profilés porteurs verticaux 4 en forme de I, par exemple en aluminium. Entre les profilés porteurs verticaux 4, on pose des panneaux isolants 5, qui sont découpés à l'endroit des baies 3. On fixe sur les profilés porteurs verticaux 4 des profilés porteurs horizontaux 6. Des plaques de revêtement 7 formant le parement extérieur sont fixées aux profilés porteurs horizontaux 6. Les panneaux isolants 5 ont une épaisseur qui est moindre que la hauteur des profilés verticaux 4 en I laissant ainsi entre les panneaux isolants 5 et les plaques de revêtement 7 un espace 8 qui permet une ventilation naturelle verticale, spécifique des façades légères ventilées.In Figs. 1 to 3, a heavy frame 1 of reinforced concrete carries a filling 2 of reinforced concrete or masonry which forms a heavy interior wall comprising openings 3. On the exterior face of the interior wall and of the framework are fixed vertical support profiles 4 I-shaped, for example aluminum. Between the vertical load-bearing profiles 4, insulating panels 5 are placed, which are cut at the location of the openings 3. Horizontal load-bearing profiles are fixed on the vertical load-bearing profiles 4 6. Cover plates 7 forming the external facing are fixed to the horizontal support profiles 6. The insulating panels 5 have a thickness which is less than the height of the vertical profiles 4 in I thus leaving between the insulating panels 5 and the covering plates 7 a space 8 which allows natural vertical ventilation, specific to the light ventilated façades.

La Fig. 4 est une vue éclatée d'un panneau intérieur avec baie, suivant l'invention, destiné à porter un parement extérieur pour former ensemble une façade légère ventilée. La Fig. 5 est une coupe horizontale et la Fig. 6 une coupe verticale d'une partie de façade légère ventilée dont le panneau intérieur est réalisé suivant l'invention. La Fig. 7 est une coupe horizontale et la Fig. 8 une coupe verticale d'une baie de fenêtre, comme celle de la Fig. 4, dans laquelle les châssis et vitrages ne sont pas représentés.Fig. 4 is an exploded view of an interior panel with opening, according to the invention, intended to carry an exterior facing to form together a light ventilated facade. Fig. 5 is a horizontal section and FIG. 6 a vertical section of a portion of ventilated light facade whose inner panel is produced according to the invention. Fig. 7 is a horizontal section and FIG. 8 is a vertical section through a window opening, like that of FIG. 4, in which the frames and glazing are not shown.

Sur les Fig. 4 à 8, des profilés verticaux 9 en forme de C stylisé forment, par juxtaposition et collage ou vissage, un panneau intérieur 10 suivant l'invention destiné à recouvrir l'ossature du bâtiment et à porter le parement extérieurs Les Fig. 4 à 8 illustrent bien que le panneau intérieur 10 suivant l'invention remplit à lui seul et avantageusement les mêmes fonctions que le béton armé ou la maçonnerie 2 et les profilés en aluminium 4 représentés aux Fig. 1 à 3. Chaque profilé vertical 9 a un pan central dorsal 11 auquel se raccordent, à angle droit, deux pans latéraux 12 portant eux-mêmes un rebord, à angle droit. Les deux rebords 13 sont dirigés l'un vers l'autre. La juxtaposition de plusieurs profilés 9 en C, côte à côte, forme le panneau 10. La suite des pans dorsaux 11 des profilés verticaux 9 forme une feuille dorsale continue destinée à être fixée à l'ossature du bâtiment (non représentée).In Figs. 4 to 8, vertical profiles 9 in the form of a stylized C form, by juxtaposition and gluing or screwing, an interior panel 10 according to the invention intended to cover the framework of the building and to carry the exterior facing. FIGS. 4 to 8 illustrate well that the interior panel 10 according to the invention alone and advantageously fulfills the same functions as reinforced concrete or masonry 2 and the aluminum profiles 4 shown in FIGS. 1 to 3. Each vertical section 9 has a central back panel 11 to which are connected, at right angles, two side panels 12 themselves carrying a rim, at right angles. The two flanges 13 are directed towards each other. The juxtaposition of several sections 9 in C, side by side, forms the panel 10. The series of back panels 11 of the vertical sections 9 forms a continuous back sheet intended to be fixed to the frame of the building (not shown).

A l'endroit où l'on désire ménager une baie 14, par exemple pour une fenêtre, dans le panneau intérieur 10, on utilise des profilés 9 plus courts, dont la longueur correspond respectivement à la hauteur 15 requise au-dessus de la baie 14 et à la hauteur 16 requise au-dessous de la baie 14 en laissant l'espace de la baie 14 vide. Cette technique est économique en matériau et en temps.In the place where it is desired to provide a bay 14, for example for a window, in the interior panel 10, shorter profiles 9 are used, the length of which corresponds respectively to the height 15 required above the bay 14 and at the required height 16 below the bay 14, leaving the bay 14 space empty. This technique is economical in material and time.

Pour assurer la raideur du panneau 10 dans le sens horizontal, on fixe, le long du bord supérieur du panneau 10, un profilé raidisseur supérieur 17 qui est un profilé en caisson, en substance en forme de P. On fixe un profilé raidisseur 18, identique mais renversé, le long du bord inférieur du panneau 10.To ensure the stiffness of the panel 10 in the horizontal direction, an upper stiffening profile 17 is fixed along the upper edge of the panel 10 which is a box profile, substantially in the form of a P. A stiffening profile 18 is fixed, identical but reversed, along the lower edge of the panel 10.

De manière analogue, on fixe le long du bord supérieur de la baie 14 un profilé raidisseur 19 qui forme un dessous de linteau, et le long du bord inférieur de la baie 14 un profilé raidisseur 20 qui forme un appui d'allège.Similarly, along the upper edge of the opening 14 is fixed a stiffening section 19 which forms a lintel underside, and along the lower edge of the opening 14 a stiffening section 20 which forms a light support.

L'espace compris dans les profilés raidisseurs 17, 18, 19 et 20 est rempli d'une matière isolante thermique et acoustique.The space included in the stiffening profiles 17, 18, 19 and 20 is filled with a thermal and acoustic insulating material.

La raideur du panneau intérieur 10 dans le sens vertical est assuré d'office par la forme des profilés verticaux 9 qui le composent, grâce aux pans latéraux 12 et aux rebords 13.The stiffness of the interior panel 10 in the vertical direction is automatically ensured by the shape of the vertical profiles 9 which compose it, by virtue of the side panels 12 and the flanges 13.

Un matériau isolant 21 couvre le pan dorsal 11 à l'intérieur de chaque profilé 9 en C, l'épaisseur de l'isolant 21 est moindre que la largeur des pans latéraux 12. L'espace libre laissé entre l'isolant 21 et le rebord 13 constitue une lame d'air de ventilation verticale 8 le long de l'ouverture du profilé 9 en C. Les rebords 13 des profilés 9 portent des profilés horizontaux 6 auxquels on fixe le parement extérieur 7.An insulating material 21 covers the back panel 11 inside each section 9 at C, the thickness of the insulator 21 is less than the width of the side panels 12. The free space left between the insulator 21 and the rim 13 constitutes a vertical ventilation air gap 8 along the opening of the profile 9 at C. The edges 13 of the profiles 9 carry horizontal profiles 6 to which the outer facing 7 is fixed.

Le fait que les panneaux intérieurs 10 selon l'invention sont réalisés par juxtaposition de profilés verticaux 9 en C permet une grande variété de dimensions de ces panneaux 10 et de celles des baies 14 qu'ils comportent. On peut varier la largeur de ces profilés 9 de manière à disposer d'un jeu de largeurs standards, par exemple de 30, 45 et 60 cm. Diverses combinaisons de ces profilés 9 de largeurs différentes permettent ainsi la réalisation de panneaux intérieurs 10 pourvus de baies 14 de largeurs très diverses, éventuellement dans un même bâtiment. Quant à la variation de la hauteur des baies, elle s'obtient de manière plus simple encore, par découpage, avant assemblage, des profilés 9 en C à la longueur voulue correspondant à la hauteur 15 désirée pour le linteau au-dessus de la baie 14 et à la hauteur 16 désirée pour les allèges au-dessous de la baie 14, pour laisser à la baie 14 une ouverture libre de la dimension désirée. Cette technique permet la réalisation de baies 14 de dimensions très variées d'une manière très simple et sans chute inutile de matériaux. Les schémas A à F de la Fig. 9 montrent quelques possibilités d'agencement de baies 14 de dimensions variées. L'invention résoud ainsi, d'une manière très simple, le difficile problème de la réalisation de baies 14 de dimensions très variées dans des façades légères ventilées produites industriellement.The fact that the interior panels 10 according to the invention are produced by juxtaposition of vertical profiles 9 in C allows a wide variety of dimensions of these panels 10 and those of the bays 14 which they comprise. The width of these sections 9 can be varied so as to have a set of standard widths, for example 30, 45 and 60 cm. Various combinations of these profiles 9 of different widths thus allow the production of interior panels 10 provided with bays 14 of very different widths, possibly in the same building. As for the variation of the height of the bays, it is obtained even more simply, by cutting, before assembly, profiles 9 in C at the desired length corresponding to the desired height 15 for the lintel above the bay 14 and at the desired height 16 for the lighters below the bay 14, to leave the bay 14 a free opening of the desired dimension. This technique allows the production of bays 14 of very varied dimensions in a very simple manner and without unnecessary drop of materials. The diagrams A to F of FIG. 9 show some possibilities of arrangement of bays 14 of various dimensions. The invention thus solves, in a very simple manner, the difficult problem of producing bays 14 of very varied dimensions in ventilated light facades produced industrially.

Un autre avantage qui découle de la construction de panneaux intérieurs à partir de profilés verticaux 9 en C en matière composite est le fait qu'on n'est pas obligé de s'en tenir à une épaisseur uniforme de la matière constitutive desdits profilés. Ainsi, comme le montre la Fig. 10, on peut créer un rebord en surépaisseur 22, ainsi qu'une surépaisseur 23 de la partie correspondante du pan dorsal 11, de manière à augmenter l'inertie des profilés 9 en C, pour qu'ils résistent mieux aux sollicitations dynamiques de pression et de dépression engendrées par le vent et aux sollicitations statiques engendrées par le poids plus ou moins important, suivant le matériau choisi, du parement extérieur 7 que ces profilés 9 doivent supporter.Another advantage which results from the construction of interior panels from vertical profiles 9 in C in composite material is the fact that one is not obliged to stick to a uniform thickness of the material of said profiles. Thus, as shown in FIG. 10, it is possible to create a rim in excess thickness 22, as well as an excess thickness 23 in the corresponding part of the back panel 11, so as to increase the inertia of the profiles 9 in C, so that they better resist dynamic stresses of pressure. and of depression generated by the wind and the static stresses generated by the more or less significant weight, depending on the material chosen, of the exterior facing 7 that these sections 9 must support.

On peut également apporter d'autres modifications aux profilés verticaux 9 en C. Ainsi, comme le montre la Fig. 11, on peut pultruder un profilé qui, en outre, porte une nervure 24 au pan latéral 12 entre le panneau d'isolation 21 et le rebord 22. La nervure 24 maintient une feuille 25 contre la surface de l'isolant 21, par exemple une feuille d'aluminium. Cette disposition confère à la couche d'isolant thermique 21 une meilleure capacité de jouer en même temps un rôle d'isolation acoustique.Other modifications can also be made to the vertical sections 9 at C. Thus, as shown in FIG. 11, a profile can be pultruded which, in addition, carries a rib 24 in the side panel 12 between the insulation panel 21 and the flange 22. The rib 24 holds a sheet 25 against the surface of the insulation 21, for example aluminum foil. This arrangement gives the thermal insulating layer 21 a better ability to play at the same time an acoustic insulation role.

Dans la forme d'exécution montrée à la Fig. 11, le panneau intérieur 10 comporte, en outre, des profilés 26 en forme de T. Ces profilés 26 en matière composite pultrudée sont collés contre la face dorsale du panneau intérieur 10, aux endroits de jonction des profilés 9 en C, renforçant ainsi la liaison entre ces profilés 9 et augmentant encore la rigidité du panneau intérieur 10. L'espace entre les profilés 26 successifs est rempli d'un matériau isolant acoustique et thermique 27. Cet isolant 27 est recouvert d'une paroi mince 28 en tôle ou en fibres-­ciment, par exemple.In the embodiment shown in FIG. 11, the interior panel 10 further comprises T-shaped profiles 26. These profiles 26 of pultruded composite material are bonded against the dorsal face of the interior panel 10, at the junction points of the profiles 9 at C, thus strengthening the connection between these sections 9 and further increasing the rigidity of the interior panel 10. The space between the successive sections 26 is filled with an acoustic and thermal insulating material 27. This insulator 27 is covered with a thin wall 28 in sheet metal or fiber cement, for example.

La forme d'exécution montrée à la Fig. 11 améliore encore nettement l'isolation acoustique et thermique du panneau intérieur 10.The embodiment shown in FIG. 11 further clearly improves the acoustic and thermal insulation of the interior panel 10.

Les Fig. 12 et 13 montrent qu'en apportant une modification aux profilés 9, 19 et 20 qui encadrent une baie 14, on peut réaliser un dormant de fenêtre incorporé dans le panneau intérieur 10 lui-même. A cette fin, le pan latéral 12 du profilé vertical 9 en C, qui forme le tableau vertical de l'encadrement de baie 14, présente, à l'endroit de la baie 14, deux pans dirigés vers l'intérieur donnant au pan latéral 12 un profil 29 en forme de F. De même, le profilé raidisseur horizontal supérieur 19, formant linteau, et le profilé raidisseur inférieur 20, formant appui d'allège, présentent vers l'intérieur de la baie 14 des motifs 29 en F. L'ensemble de ces motifs 29 en F forme un dormant de fenêtre à double battée. Le profilé raidisseur horizontal inférieur 20 est prolongé par un seuil de fenêtre ou appui d'allège 30 surplombant le panneau de parement extérieur 7 et laissant un espace 31 permettant la ventilation de la lame d'air verticale 8 le long des profilés verticaux 9 en C.Figs. 12 and 13 show that by making a modification to the sections 9, 19 and 20 which frame a bay 14, it is possible to produce a window frame incorporated in the interior panel 10 itself. To this end, the side panel 12 of the vertical section 9 at C, which forms the vertical table of the window frame 14, has, at the location of the window 14, two sides facing inwards giving to the side panel 12 a profile 29 in the form of F. Similarly, the upper horizontal stiffening profile 19, forming a lintel, and the lower stiffening profile 20, forming a light support, have patterns 29 in F. towards the interior of the opening 14. All of these patterns 29 at F form a window frame with double battée. The lower horizontal stiffener profile 20 is extended by a window threshold or sill support 30 overhanging the exterior facing panel 7 and leaving a space 31 allowing the ventilation of the vertical air gap 8 along the vertical profiles 9 at C .

La Fig. 14 est une coupe horizontale d'un profilé vertical 9 comme on peut également le voir à la Fig. 5. Il s'agit d'un profilé en forme de C stylisé, dont le pan central dorsal 11 consiste en une seule feuille.Fig. 14 is a horizontal section of a vertical profile 9 as can also be seen in FIG. 5. It is a stylized C-shaped profile, of which the central dorsal panel 11 consists of a single sheet.

Suivant des variantes de réalisation, le pan central dorsal de ces profilés verticaux peut cependant être formé de deux ou plusieurs feuilles parallèles entre elles, reliées par les pans latéraux 12.According to variant embodiments, the central dorsal panel of these vertical sections can however be formed from two or more sheets parallel to each other, connected by the side panels 12.

C'est ainsi que dans le profilé vertical 32 montré à la Fig. 15, le pan central dorsal est formé de deux feuilles 33 et 34 parallèles entre elles. L'espace entre ces feuilles 33 et 34 est rempli d'un matériau isolant acoustique et thermique 35.Thus in the vertical profile 32 shown in FIG. 15, the central dorsal panel is formed by two sheets 33 and 34 parallel to each other. The space between these sheets 33 and 34 is filled with an acoustic and thermal insulating material 35.

De manière analogue, le profilé vertical 36 (Fig. 16) comporte un pan central dorsal formé de trois feuilles 37, 38 et 39 parallèles entre elles. Ici également, l'espace entre ces feuilles 37, 38 et 39 est rempli d'un matériau isolant acoustique et thermique 35.Similarly, the vertical profile 36 (Fig. 16) has a central back panel formed by three sheets 37, 38 and 39 which are parallel to each other. Here also, the space between these sheets 37, 38 and 39 is filled with an acoustic and thermal insulating material 35.

Sur les Fig. 17 et 18, les panneaux intérieurs 10 sont fixés aux ossatures constituées d'unités de construction tridimensionnelles modulaires 40 telles que décrites dans le brevet européen n° 0 012 736. Les bords de ces unités de construction 40, à savoir les colonnes verticales 41 et les poutres horizontales 42 ne se touchent pas mais ménagent un vide vertical 43 et un vide horizontal 44 respectivement, pour le passage des tuyauteries et câbles.In Figs. 17 and 18, the interior panels 10 are fixed to the frameworks made up of three-dimensional modular construction units 40 as described in European Patent No. 0 012 736. The edges of these construction units 40, namely the vertical columns 41 and the horizontal beams 42 do not touch but provide a vertical vacuum 43 and a horizontal vacuum 44 respectively, for the passage of pipes and cables.

Il est avantageux de monter les panneaux intérieurs 10 suivant l'invention sur les unités de construction 40 lors de la réalisation de celles-ci en usine.It is advantageous to mount the interior panels 10 according to the invention on the construction units 40 when these are produced in the factory.

Que les panneaux intérieurs 10 soient montés sur des unités de construction modulaires préfabriquées ou sur l'ossature d'autres bâtiments, il est généralement souhaitable de ménager un espace entre les panneaux intérieurs 10 juxtaposés et superposés.Whether the interior panels 10 are mounted on prefabricated modular construction units or on the framework of other buildings, it is generally desirable to provide a space between the interior panels 10 juxtaposed and superimposed.

Le raccord entre les panneaux intérieurs 10 peut se faire comme montré aux Fig. 17 et 18. Des plats 45 en aluminium ou en matière polymère renforcée sont fixés aux bords arrière des panneaux 10. Contre ces plats 45 qui servent de battées, on colle ou visse des profilés 46 en forme de U en une matière souple mais étanche et on remplit l'espace compris dans ces profilés 46 en forme de U d'un bourrage 47 en une matière isolante thermique.The connection between the interior panels 10 can be made as shown in Figs. 17 and 18. Dishes 45 made of aluminum or reinforced polymer material are fixed to the rear edges of the panels 10. Against these dishes 45 which serve as battées, glues or screws are formed on the U-shaped profiles 46 in a flexible but waterproof material and the space included in these U-shaped sections 46 is filled with stuffing 47 made of a thermal insulating material.

Les panneaux intérieurs 10 sont, de préférence, fixés à l'ossature du bâtiment (et surtout aux poutres horizontales de cette ossature) au moyen de boulons (non représentés). Ces boulons traversent le pan central dorsal 11 des profilés 9 en C à proximité des pans latéraux 12, c'est-à-dire à l'endroit où il y a une surépaisseur 23 du pan dorsal 11. Des pièces d'espacement (non représentées) sont généralement interposées entre l'ossature du bâtiment et la face dorsale des panneaux intérieurs 10.The interior panels 10 are preferably fixed to the frame of the building (and especially to the horizontal beams of this frame) by means of bolts (not shown). These bolts pass through the central back panel 11 of the profiles 9 at C near the side panels 12, that is to say at the place where there is an excess thickness 23 of the back panel 11. Spacers (not shown) are generally interposed between the structure of the building and the dorsal side of the interior panels 10.
