Description

L'invention concerne les façades de bâtiment et les éléments pour de telles façades.The invention relates to building facades and elements for such facades.

On connaít des éléments pour façade comportant une âme en matériau alvéolaire et un panneau de parement en matière plastique supporté par l'âme et visible depuis l'extérieur du bâtiment. De tels éléments ont un poids réduit et permettent de constituer une façade légère. Toutefois, le matériau du panneau de parement a généralement un coefficient de dilatation élevé par rapport à celui de l'âme, de sorte qu'il est difficile d'obtenir une fixation fiable et simple du panneau à l'âme.We know elements for facade comprising a core of cellular material and a facing panel of plastic material supported by the core and visible from outside the building. Such elements have weight reduced and make it possible to constitute a light facade. However, the material of the facing panel has generally a high coefficient of expansion by compared to that of the soul, so it's difficult to obtain a reliable and simple fixing of the panel to blade.

Un but de l'invention est de proposer un élément pour façade dans lequel le panneau est fixé de façon fiable et simple à son support.An object of the invention is to propose an element for facades in which the panel is fixed so reliable and simple to support.

En vue de la réalisation de ce but, on prévoit selon l'invention un élément pour façade, comportant un support et un panneau comprenant au moins deux parties de fixation fixées au support et une paroi généralement plane s'étendant entre les deux parties de fixation, dans lequel au moins l'une des parties de fixation s'étend en retrait du plan de la paroi et est déformable de sorte que la paroi est libre de se mouvoir parallèlement à elle-même par rapport au support lors d'une modification de la température du panneau.In order to achieve this goal, provision is made according to the invention a facade element, comprising a support and a panel comprising at least two parts of fixing fixed to the support and a wall generally plane extending between the two fixing parts, in which at least one of the fixing parts extends back from the wall plane and is deformable so that the wall is free to move parallel to itself with respect to the support during a change in the panel temperature.

Ainsi, la déformation de la ou chaque partie de fixation autorise la paroi à se dilater suivant son plan sans menacer la qualité de la fixation du panneau au support.So the deformation of the or each part of fixing allows the wall to expand along its plane without threatening the quality of the fixing of the panel to the support.

Avantageusement, le support comporte une âme présentant au moins une face latérale s'étendant suivant une direction générale perpendiculaire à la paroi du panneau, le support comportant des moyens de fixation de la ou chaque partie de fixation s'étendant en regard et à distance de la face latérale de l'âme.Advantageously, the support comprises a core having at least one lateral face extending along a general direction perpendicular to the wall of the panel, the support comprising means for fixing the or each fixing part extending opposite and away from the lateral face of the core.

Avantageusement, les moyens de fixation sont reliés à une face arrière de l'âme opposée à la paroi du panneau.Advantageously, the fixing means are connected to a rear face of the core opposite the wall of the sign.

Avantageusement, les moyens de fixation sont agencés pour recevoir la partie de fixation lors d'un déplacement relatif du support par rapport au panneau perpendiculairement à la paroi.Advantageously, the fixing means are arranged to receive the fixing part during a relative displacement of the support relative to the panel perpendicular to the wall.

Ainsi, la fixation du panneau au support est simple à effectuer.Thus, the fixing of the panel to the support is simple to perform.

Avantageusement, le support comporte une surface de guidage adaptée à guider la partie de fixation depuis une position voisine des moyens de fixation jusqu'à ceux-ci lors d'un déplacement relatif du support par rapport au panneau perpendiculairement à la paroi.Advantageously, the support has a surface guide adapted to guide the fixing part from a position close to the fixing means up to these during a relative displacement of the support by relation to the panel perpendicular to the wall.

Ainsi, on simplifie encore la fixation du panneau au support.Thus, it further simplifies the fixing of the panel to the support.

Avantageusement, la surface de guidage est conformée pour éloigner les parties de fixation l'une de l'autre lors du déplacement du support.Advantageously, the guide surface is shaped to distance the fixing parts one of the other when moving the support.

Ainsi, on autorise la partie de fixation à se déformer suivant une grande amplitude lors d'une dilatation de la paroi.Thus, the fixing part is allowed to stand deform by a large amplitude during a wall dilation.

Avantageusement, le support comporte une première et une deuxième pièces d'assemblage constituant les moyens de fixation, la première pièce d'assemblage étant fixée à l'âme et s'étendant en regard de celle-ci et la deuxième pièce d'assemblage s'étendant à l'extérieur de l'élément et étant fixée à la première pièce d'assemblage avec interposition d'un joint d'interposition en matériau isolant thermique. Ainsi, on limite les transferts thermiques depuis la deuxième pièce d'assemblage en contact direct avec l'air ambiant, et la première pièce d'assemblage adjacente à l'âme.Advantageously, the support comprises a first and second assembly parts constituting the fixing means, the first assembly part being attached to the core and extending opposite it and the second assembly piece extending to the outside of the element and being attached to the first assembly piece with interposition of a seal of thermal insulating material. So, we limits heat transfers since the second assembly part in direct contact with the ambient air, and the first assembly part adjacent to the core.

Avantageusement, la première pièce d'assemblage est profilée et s'étend le long d'une face latérale de l'âme.Advantageously, the first assembly part is profiled and extends along a lateral face of blade.

Ainsi, la première pièce d'assemblage constitue une pièce de renfort améliorant la résistance mécanique de l'âme.Thus, the first assembly part constitutes a reinforcement piece improving mechanical strength of soul.

Avantageusement, l'âme comprend un matériau alvéolaire.Advantageously, the core comprises a material alveolar.

On obtient ainsi un élément de façade de poids réduit.This gives a weighty facade element reduced.

Avantageusement, le panneau comprend une matière plastique pleine.Advantageously, the panel comprises a material full plastic.

Ainsi, le panneau peut revêtir des aspects très variés suivant l'esthétique souhaitée pour la façade.Thus, the panel can assume very varied according to the aesthetics desired for the facade.

On prévoit également selon l'invention un ensemble pour la construction d'une façade, comprenant deux éléments de façade selon l'invention et un joint de liaison adapté à être fixé aux deux éléments de façade lorsque ceux-ci sont disposés en étant adjacents l'un à l'autre, de façon à interdire le passage de l'air entre les deux éléments de façade suivant une direction perpendiculaire aux parois des panneaux.There is also provided according to the invention a assembly for the construction of a facade, comprising two facade elements according to the invention and a gasket connection adapted to be fixed to the two facade elements when these are arranged adjacent to one another the other, so as to prevent the passage of air between the two facade elements in a direction perpendicular to the walls of the panels.

Ainsi, on limite les échanges thermiques entre l'extérieur et l'intérieur de la façade.Thus, we limit the heat exchanges between the exterior and interior of the facade.

Avantageusement, chaque élément de façade comporte un joint à recouvrement agencé de sorte que les joints à recouvrement de deux éléments de façade disposés en étant adjacents l'un à l'autre viennent en contact l'un avec l'autre de manière à interdire des passages de projections d'eau entre les deux éléments de façade suivant une direction perpendiculaire aux parois des panneaux.Advantageously, each facade element has a lap joint arranged so that the overlap joints of two facade elements arranged adjacent to each other come in contact with each other so as to prohibit splashes of water between the two elements of facade in a direction perpendicular to the walls Signs.

Avantageusement, la deuxième pièce d'assemblage est adaptée à recevoir en fixation au moins l'un des joints parmi les joints de recouvrement et de liaison.Advantageously, the second assembly part is suitable for receiving at least one of the joints among the cover and link joints.

On simplifie ainsi le montage des différentes parties de chaque élément de façade.This simplifies the assembly of the different parts of each facade element.

On prévoit en outre selon l'invention une façade comprenant des éléments pour façade selon l'invention, ou un ensemble selon l'invention.In addition, a facade is provided according to the invention. comprising facade elements according to the invention, or an assembly according to the invention.

La façade, dans le présent mode de réalisation de l'invention, est fixée à un bâtiment comportant plusieurs planchers horizontaux 2 constitués principalement en béton et s'étendant à des niveaux différents, les uns au-dessus des autres. Ces planchers 2 présentent chacun un bord rectiligne vertical 4, ces bords étant parallèles entre eux et inscrits dans un même plan vertical. La façade s'étend contre ces bords 4. Chaque plancher 2 présente deux faces planes horizontales supérieure 5 et inférieure 6.The facade, in this embodiment of the invention, is attached to a building comprising several horizontal floors 2 made up mainly concrete and extending to levels different, one above the other. These floors 2 each have a vertical straight edge 4, these edges being parallel to each other and inscribed in a same vertical plane. The facade extends against these edges 4. Each floor 2 has two flat faces horizontal upper 5 and lower 6.

La façade comporte des premiers éléments de façade ou trumeaux 8 et des deuxièmes éléments de façade ou éléments de remplissage 10. Chacun de ces éléments a une forme générale de parallélépipède rectangle présentant notamment une grande face avant 12 et une grande face arrière 14 généralement planes et parallèles entre elles.The facade contains the first elements of facade or trumeaux 8 and second facade elements or fillers 10. Each of these has a general shape of a rectangular parallelepiped having in particular a large front face 12 and a large rear face 14 generally flat and parallel between them.

Chaque premier et deuxième éléments de façade 8, 10 comporte une âme alvéolaire 16, par exemple en mousse de polyuréthanne. L'âme 16 présente une face avant 15 et une face arrière 17, parallèles entre elles et recouvertes par deux feuilles métalliques respectives ayant une épaisseur de 0,05 mm. L'âme 16 présente deux faces latérales rectilignes planes 20 parallèles entre elles et s'étendant verticalement. A chaque face latérale 20 est associé un renfort profilé rigide 22 en tôle galvanisée, d'épaisseur 2,5 mm, recouvrant la face latérale et une partie des faces avant 15 et arrière 17 de l'âme. Le renfort 22 est fixé à la face arrière 17 de l'âme 16 orientée vers les planchers 2 avec interposition de la feuille métallique, en réalisant un contact surface contre surface avec celle-ci. Il s'étend sur toute la hauteur de la face arrière 17 de l'âme.Each first and second facade elements 8, 10 comprises a honeycomb core 16, for example made of foam polyurethane. The core 16 has a front face 15 and a rear face 17, parallel to each other and covered by two respective metal sheets having a thickness of 0.05 mm. Soul 16 has two flat rectilinear side faces 20 parallel between them and extending vertically. On each side side 20 is associated with a rigid profiled reinforcement 22 in galvanized sheet, 2.5 mm thick, covering the face side and part of the front 15 and rear 17 faces of soul. The reinforcement 22 is fixed to the rear face 17 of the core 16 oriented towards the floors 2 with interposition of the metal sheet, making a surface-to-surface contact with it. He's stretching over the entire height of the rear face 17 of the core.

Les éléments de remplissage 10 comportent en outre deux renforts profilés rigides horizontaux 24 associés de la même façon à deux faces rectilignes planes horizontales supérieure et inférieure de l'âme 16.The filling elements 10 include in addition to two horizontal rigid profile reinforcements 24 associated in the same way with two rectilinear faces upper and lower horizontal planes of the core 16.

Chacun des premiers et deuxièmes éléments de façade 8, 10 comporte un panneau de parement 25 en matière plastique, par exemple en PVC, s'étendant en regard de la face avant 15 de l'âme 16, parallèlement à celle-ci et la dissimulant à la vue depuis l'extérieur du bâtiment. Le panneau de parement 25 s'étend du côté extérieur de l'élément de façade pour être visible depuis l'extérieur du bâtiment. Il présente une face plane 12 constituant la face avant de l'élément de façade. Each of the first and second elements of front 8, 10 has a facing panel 25 in plastic material, for example PVC, extending look of the front face 15 of the core 16, parallel to this and hiding it from view from the outside of the building. The facing panel 25 extends from the side exterior of the facade element to be visible from outside the building. It has a face plane 12 constituting the front face of the element of facade.

La façade comporte en outre des menuiseries telles que des fenêtres 26 ou des portes, de forme générale plane et rectangulaire en élévation.The facade also has joinery such as windows 26 or doors, shaped general planar and rectangular in elevation.

Les premiers et deuxièmes éléments de façade 8, 10 et les menuiseries 26 sont disposées les uns à côté des autres dans un même plan adjacent aux bords 4 des planchers 2.The first and second facade elements 8, 10 and the joinery 26 are arranged next to each other others in the same plane adjacent to the edges 4 of floors 2.

Les premiers éléments de façade 8 sont fixés aux planchers 2 et uniquement à ceux-ci, au moyen de premiers organes de fixation ou équerres 30. Les premiers éléments de façade 8 sont disposés en plusieurs rangées verticales parallèles entre elles, et espacées les unes des autres. Les premiers éléments de façade 8 de chaque rangée sont adjacents les uns aux autres et ont leurs faces latérales verticales alignées. Chaque premier élément de façade 8 a une dimension longitudinale ou hauteur h suivant la direction verticale perpendiculaire aux planchers 3. Cette dimension h est égale à la distance d séparant les faces homologues (par exemple les faces supérieures 5) de deux planchers 2 adjacents l'un de l'autre suivant la direction verticale. Cette distance d est la hauteur d'un étage du bâtiment.The first facade elements 8 are fixed to the floors 2 and only to these, by means of first fasteners or brackets 30. The first facade elements 8 are arranged in several vertical rows parallel to each other, spaced apart each other. The first facade elements 8 of each row are adjacent to each other and have their vertical side faces aligned. Each first facade element 8 has a dimension longitudinal or height h in the direction vertical perpendicular to the floors 3. This dimension h is equal to the distance d between the faces counterparts (for example the upper faces 5) of two floors 2 adjacent to each other according to the vertical direction. This distance d is the height of a floor of the building.

Chaque premier élément de façade 8 est fixé à deux planchers adjacents 2 s'étendant à des niveaux différents. Il est fixé à chacun de ces planchers par deux équerres 30 qui fixent également à ce même plancher 2 le premier élément de façade 8 suivant dans la rangée.Each first facade element 8 is fixed to two adjacent floors 2 extending to levels different. It is attached to each of these floors by two brackets 30 which also fix to this same floor 2 the first front element 8 following in the row.

Chaque équerre 30 comporte une première et une deuxième platines 32, 34 fixées l'une à l'autre en formant un angle droit. La première platine 32 comporte quatre orifices traversants 44 pour la fixation à l'équerre de deux premiers éléments de façade 8, chacun par deux vis ou rivets traversant deux des orifices 44. La première platine 32 s'étend verticalement, parallèlement à la face arrière 17 de l'âme et est fixée à chacun des deux premiers éléments de façade 8, par exemple au moyen de deux vis ou rivets d'axe 90. L'une des tiges traverse l'âme 16 de part en part suivant son épaisseur et est reliée à l'un des renforts rigides verticaux 22 de part et d'autre de l'âme, et l'autre tige traverse le renfort 22 et l'âme 16. La deuxième platine 34 s'étend horizontalement et est noyée dans le plancher 2. La deuxième platine 34 présente trois logements circulaires filetés 38 traversant l'épaisseur de la platine et disposés en triangle. L'équerre comporte trois vis- pointeaux 40 engagées dans les logements 38 respectifs de façon à s'étendre en saillie d'une face de la deuxième platine 34 opposée à la première platine 32.Each bracket 30 has a first and a second plates 32, 34 fixed to each other in forming a right angle. The first plate 32 comprises four through holes 44 for fixing to the square of the first two facade elements 8, each by two screws or rivets passing through two of the holes 44. The first plate 32 extends vertically, parallel to the rear face 17 of the core and is fixed to each of the first two facade elements 8, by example by means of two screws or rivets with axis 90. One rods through the core 16 right through following its thickness and is connected to one of the rigid reinforcements vertical 22 on either side of the core, and the other rod passes through the reinforcement 22 and the core 16. The second plate 34 extends horizontally and is embedded in the floor 2. The second plate 34 has three circular threaded housings 38 running through the thickness of the plate and arranged in a triangle. The square comprises three needle screws 40 engaged in the respective housings 38 so as to project of a face of the second plate 34 opposite the first deck 32.

L'équerre 30 est mise en place de la façon suivante. On réalise une dalle de béton horizontale 36 constituant le gros-oeuvre du plancher 2, en ménageant dans cette dalle une feuillure adjacente au bord 4 du plancher et présentant une face plane 37 généralement horizontale. On dispose l'équerre avec la première platine 32 s'étendant verticalement près du bord 4 du plancher et dirigée vers le haut, les extrémités des trois vis-pointeaux 40 venant en contact avec la face plane 37 de la feuillure. On actionne ensuite l'une ou plusieurs des vis-pointeaux 40 en vue de régler la position angulaire de l'équerre 30 par rapport à la face 37 de la feuillure suivant deux directions horizontales perpendiculaires l'une de l'autre, par exemple, les directions X et Y de la figure 3. La deuxième platine 34 présente deux orifices 42, dont l'un est proche de la première platine 32, et long, et l'autre est éloigné de la première platine et circulaire, et deux vis de solidarisation 39 engagées dans les orifices 42 respectifs. Après que la position angulaire souhaitée de l'équerre a été obtenue, on visse les vis de solidarisation 39 dans la dalle 36 pour fixer rigidement l'équerre à la dalle. Puis on coule dans la feuillure un matériau de remplissage tel qu'un mortier 41, emplissant toute la feuillure et recouvrant la deuxième platine horizontale 34 sans recouvrir la première platine verticale 32. Ce matériau immobilise l'équerre après durcissement. Avant serrage des vis de solidarisation 39, on peut interposer une ou plusieurs cales 43 entre la deuxième platine horizontale 34 et la face supérieure 37 de la feuillure. Les équerres 30 ont des dimensions très inférieures aux dimensions des premiers et deuxièmes éléments de façade 8, 10 suivant les directions horizontale et verticale, et notamment inférieures à la plus grande dimension de ces éléments.The bracket 30 is set up in the way next. We realize a horizontal concrete slab 36 constituting the main structure of floor 2, sparing in this slab a rebate adjacent to edge 4 of the floor and having a flat face 37 generally horizontal. We place the square with the first plate 32 extending vertically near the edge 4 of the floor and directed upwards, the ends of the three needle screws 40 coming into contact with the face plane 37 of the rebate. We then activate one or several of the needle screws 40 in order to adjust the angular position of the bracket 30 relative to the face 37 of the rebate in two horizontal directions perpendicular to each other, for example, the directions X and Y of figure 3. The second plate 34 has two orifices 42, one of which is close to the first stage 32, and long, and the other is far from the first circular plate, and two screws joining 39 engaged in the orifices 42 respective. After the desired angular position of the square has been obtained, we screw the screws of joining 39 in the slab 36 to rigidly fix square to the slab. Then we sink into the rebate one filling material such as mortar 41, filling all the rebate and covering the second plate horizontal 34 without covering the first plate vertical 32. This material immobilizes the square after hardening. Before tightening the fixing screws 39, one or more wedges 43 can be interposed between the second horizontal plate 34 and the upper face 37 of the rebate. The 30 brackets have dimensions very much smaller than the first and second facade elements 8, 10 according to the horizontal and vertical directions, including smaller than the largest dimension of these elements.

Les deuxièmes éléments de façade 10 et les menuiseries 26 ont les mêmes dimensions horizontales ou longueur, et sont disposés en plusieurs rangées verticales espacées les unes des autres et alternées avec les rangées des premiers éléments de façade 8. Dans chaque rangée, les deuxièmes éléments de façade 10 et les menuiseries 26 sont alternées et ont leurs faces latérales verticales alignées entre elles. Les deuxièmes éléments de façade 10 présentent une dimension verticale ou hauteur f, et les menuiseries 26 présentent une dimension verticale ou hauteur g. La somme de la hauteur f et de la hauteur g est égale à la hauteur h des premiers éléments de façade 8.The second facade elements 10 and the joinery 26 have the same horizontal dimensions or length, and are arranged in several rows vertical spaced from each other and alternating with the rows of the first facade elements 8. In each row, the second facade elements 10 and joinery 26 are alternated and have their faces vertical sides aligned with each other. The second façade elements 10 have a vertical dimension or height f, and the joinery 26 has a vertical dimension or height g. The sum of the height f and the height g is equal to the height h of first facade elements 8.

Chaque deuxième élément de façade 10 s'étend en regard de deux premiers éléments de façade 8 de chaque rangée adjacente. Chaque deuxième élément de façade 10 est fixé à ces quatre premiers éléments de façade 8 et seulement à ceux-ci. Chaque menuiserie 26 est fixée à un premier élément de façade 8 de chaque rangée adjacente et seulement à ceux-ci.Each second facade element 10 extends in look of the first two facade elements 8 of each adjacent row. Each second facade element 10 is attached to these first four facade elements 8 and only to these. Each joinery 26 is fixed to a first facade element 8 of each adjacent row and only to these.

La fixation des deuxièmes éléments de façade 10 est effectuée au moyen de deuxièmes organes de fixation tels que des pattes métalliques planes allongées horizontales 46 fixées aux renforts verticaux 22 des premiers éléments de façade 8. La patte 46 présente six orifices traversants 48. Deux de ces orifices 48 reçoivent des attaches telles que des vis ou rivets d'axe 95 traversant un renfort vertical 22 et l'âme 16 du premier élément de façade 8 associé. Un troisième orifice 48 reçoit une attache d'axe 96 traversant un renfort vertical 22 et l'âme 16 du deuxième élément de façade 10. Deux autres orifices 48 reçoivent deux attaches d'axe 97 traversant l'un des renforts horizontaux 24 du deuxième élément de façade 10.The fixing of the second facade elements 10 is carried out by means of second fasteners such as elongated flat metal legs horizontal 46 fixed to the vertical reinforcements 22 of the first facade elements 8. Leg 46 has six through holes 48. Two of these holes 48 receive fasteners such as screws or rivets of axis 95 passing through a vertical reinforcement 22 and the core 16 of the first associated facade element 8. A third orifice 48 receives a pin attachment 96 passing through a vertical reinforcement 22 and the core 16 of the second element of facade 10. Two other orifices 48 receive two axis 97 fasteners passing through one of the reinforcements horizontal 24 of the second facade element 10.

Les panneaux 25 des premiers éléments de façade 8 ont un profil en coupe verticale transversale à la façade, tel que le panneau présente une zone supérieure 25a qui est proche de l'âme 16 et une zone inférieure 25b qui est distante de l'âme, et recouvre par l'extérieur la zone supérieure 25a du premier élément de façade 8 adjacent dans la rangée. On obtient ainsi une disposition en tuiles qui dissimule à la vue les jonctions entre les premiers éléments de façade 8 au niveau de leurs faces horizontales.The panels 25 of the first facade elements 8 have a profile in vertical section transverse to the front, such that the panel has an upper zone 25a which is close to the core 16 and a lower zone 25b which is distant from the core, and covers by outside the upper zone 25a of the first element of facade 8 adjacent in the row. We thus obtain a arrangement in tiles which hides from view the junctions between the first facade elements 8 to level of their horizontal faces.

Cette façade est donc construite au moyen d'un ensemble comprenant des premiers éléments 8 comportant une âme alvéolaire 16 et adaptés à être fixés à un bâtiment, des deuxièmes éléments 10, et des moyens de fixation 30 des deuxièmes éléments 10 aux premiers éléments 8, avec les premiers et deuxièmes éléments 8, 10 s'étendant dans un même plan.This facade is therefore constructed by means of a assembly comprising first elements 8 comprising a cellular core 16 and adapted to be fixed to a building, second elements 10, and means for attachment 30 of the second elements 10 to the first elements 8, with the first and second elements 8, 10 extending in the same plane.

Cette construction est effectuée en fixant les premiers éléments 8 au bâtiment, en disposant les premiers éléments 8 et les deuxièmes éléments 10 dans un même plan vertical, et en fixant les deuxièmes éléments 10 aux premiers éléments 8.This construction is carried out by fixing the first elements 8 to the building, arranging the first elements 8 and second elements 10 in one same vertical plane, and fixing the second elements 10 to the first elements 8.

La façade ainsi obtenue a un faible poids et est qualifiée de légère.The facade thus obtained has a low weight and is qualified as light.

On va maintenant décrire plus en détail les premier et deuxième éléments de façade 8, 10 en référence aux figures 6 à 8.We will now describe in more detail the first and second facade elements 8, 10 in reference to Figures 6 to 8.

En référence à la figure 6 représentant un premier élément de façade 8, chacun des premier et deuxième éléments de façade comporte une âme 16, en forme générale de parallélépipède rectangle, présentant deux grandes faces avant 15 et arrière 17 planes et parallèles entre elles, deux faces latérales planes 20, parallèles entre elles, perpendiculaires aux grandes faces 15 et 17, destinées à s'étendre verticalement, et deux faces d'extrémité planes parallèles entre elles, perpendiculaires aux grandes faces 15 et 17 et destinées à s'étendre horizontalement. Chaque grande face 15, 17 est recouverte par une feuille métallique.Referring to Figure 6 showing a first facade element 8, each of the first and second facade elements comprises a core 16, in general shape of a rectangular parallelepiped, presenting two large front faces 15 and rear 17 planes and mutually parallel, two flat lateral faces 20, parallel to each other, perpendicular to large faces 15 and 17, intended to extend vertically, and two plane end faces parallel to each other, perpendicular to the large faces 15 and 17 and intended to extend horizontally. Each large face 15, 17 is covered by a metal sheet.

L'élément de façade comporte deux renforts profilés métalliques ou première pièce d'assemblage 22. Chaque renfort 22 a un profil transversal en forme générale de "U", présentant une base 50, une branche avant 52 et une branche arrière 54, les branches étant parallèles l'une à l'autre. Les branches avant et arrière sont séparées l'une de l'autre par une distance légèrement supérieure à l'épaisseur de l'âme 16, à savoir la distance séparant les deux grandes faces avant 15 et arrière 17 de l'âme. Le renfort 22 a une longueur voisine de celle des faces latérales verticales 20 de l'âme. Chaque renfort 22 est disposé pour recouvrir l'une des faces latérales 20 de l'âme, la branche avant 52 venant en regard de la face avant 15, la branche arrière 54 venant en regard de la face arrière 17 et la base 50 venant en regard de la face latérale 20. La branche arrière 54 est fixée à la face arrière 17 de l'âme, à travers la feuille métallique, au moins à deux extrémités longitudinales du renfort 22, cette branche réalisant un contact surface contre surface avec cette face. La branche avant 52 s'étend parallèlement, à distance et en regard de la face avant 15, et la base 50 s'étend en regard et à distance de la face latérale 20.The facade element has two reinforcements metal profiles or first assembly part 22. Each reinforcement 22 has a shaped transverse profile general of "U", having a base 50, a branch front 52 and a rear branch 54, the branches being parallel to each other. The front and rear are separated from each other by a distance slightly greater than the thickness of the core 16, at find out the distance between the two large front faces 15 and rear 17 of the core. Reinforcement 22 has a length close to that of the vertical side faces 20 of blade. Each reinforcement 22 is arranged to cover one of the lateral faces 20 of the core, the front branch 52 coming opposite the front face 15, the branch rear 54 facing the rear face 17 and the base 50 coming opposite the lateral face 20. The rear branch 54 is fixed to the rear face 17 of the soul, through the metal sheet, at least two longitudinal ends of the reinforcement 22, this branch making surface-to-surface contact with this face. The front branch 52 extends parallel to distance from and facing the front face 15, and the base 50 extends opposite and at a distance from the lateral face 20.

La base 50 présente un profil en "S" de l'une à l'autre des deux branches 52, 54. Depuis la branche avant 52 jusqu'à la branche arrière 54, la base 50 présente une première portion plane 50a qui s'éloigne de la face latérale 20 en étant inclinée, puis une deuxième portion médiane 50b qui se rapproche de la face latérale 20, et une troisième portion plane 50c parallèle à la face latérale 20.The base 50 has an "S" profile from one to the other of the two branches 52, 54. From the branch front 52 to rear branch 54, base 50 has a first flat portion 50a which moves away from the side face 20 while being inclined, then a second middle portion 50b which approaches the lateral face 20, and a third flat portion 50c parallel to the lateral face 20.

L'élément de façade comporte deux deuxièmes pièces d'assemblage 60 associées aux premières pièces d'assemblage respectives 22. Chaque deuxième pièce d'assemblage 60 est en aluminium, est profilée et a une longueur égale à celle de la première pièce d'assemblage 22. La deuxième pièce d'assemblage 60 présente un profil transversal en "S" analogue à celui de la branche 50 de la première pièce d'assemblage 22, avec une première portion 60a, une deuxième portion 60b et une troisième portion 60c.The facade element has two second assembly parts 60 associated with the first parts respective assembly 22. Each second piece 60 is made of aluminum, is profiled and has a length equal to that of the first assembly part 22. The second assembly part 60 has a profile transverse in "S" similar to that of branch 50 of the first assembly part 22, with a first portion 60a, a second portion 60b and a third portion 60c.

La troisième portion 50c de la première pièce d'assemblage et une zone de la troisième portion 60c de la deuxième pièce d'assemblage ont sensiblement même forme et mêmes dimensions. Elles sont fixées l'une à l'autre, par exemple au moyen de vis ou de rivets d'axe 70 régulièrement espacés le long des profilés et les traversant de part en part avec interposition sur toute leur longueur d'un joint d'interposition 62 en caoutchouc synthétique formant une rupture thermique entre les deux pièces d'assemblage 22 et 60.The third portion 50c of the first piece of assembly and an area of the third portion 60c of the second assembly piece have substantially even shape and same dimensions. They are fixed one to the other, for example by means of screws or pin rivets 70 regularly spaced along the profiles and crossing right through with interposition on all their length from an interposition joint 62 in synthetic rubber forming a thermal break between the two connecting pieces 22 and 60.

Les deuxièmes portions médianes 50b et 60b s'étendent en regard l'une de l'autre. Les deux premières portions 50a et 60a s'étendent en regard l'une de l'autre en étant parallèles l'une à l'autre. La portion médiane 60a de la deuxième pièce d'assemblage 60 et plus courte que la portion médiane 50a de la première pièce d'assemblage 22, et présente des reliefs 64 en forme de dents sur une face de la portion médiane 60a orientée vers la portion médiane 50a.The second middle portions 50b and 60b lie opposite each other. Both first portions 50a and 60a extend opposite one on the other by being parallel to each other. The middle portion 60a of the second connecting piece 60 and shorter than the middle portion 50a of the first assembly part 22, and has reliefs 64 in tooth shape on one side of the middle portion 60a oriented towards the middle portion 50a.

L'âme 16 et les quatre pièces d'assemblage 22, 60 de l'élément constituent un support de l'élément.The core 16 and the four assembly pieces 22, 60 of the element constitute a support for the element.

L'élément de façade comporte un panneau 25 comprenant une paroi plane rectangulaire 66 ayant des dimensions voisines de celles des grandes faces 15, 17 de l'âme 16. Une face avant 12 de cette paroi est destinée à être visible depuis l'extérieur de la façade. Le panneau comprend quatre bords 68 de forme plane, s'étendant à partir des côtés du rectangle de la paroi 66, et opposés deux à deux de part et d'autre de celle-ci. Les bords 68 s'étendent généralement perpendiculairement à la paroi 66 et en retrait du plan de celle-ci, du côté opposé à la face visible 12. Chaque bord 68 est légèrement incliné en direction opposée au bord 68 lui faisant face.The facade element has a panel 25 comprising a rectangular flat wall 66 having dimensions close to those of the large faces 15, 17 of the core 16. A front face 12 of this wall is intended to be visible from the outside of the facade. The panel includes four edges 68 of planar shape, extending from the sides of the rectangle of the wall 66, and opposite two by two on either side thereof. The edges 68 generally extend perpendicular to the wall 66 and set back from the plane of it, on the side opposite to the visible face 12. Each edge 68 is slightly inclined in the opposite direction to the edge 68 facing him.

Les deux bords 68 destinés à s'étendre verticalement constituent deux parties de fixation du panneau 25 au support, ces deux parties s'étendant à distance l'une de l'autre et à deux extrémités du panneau.The two edges 68 intended to extend vertically constitute two fixing parts of the panel 25 to the support, these two parts extending to distance from each other and at two ends of the sign.

Les deux pièces d'assemblage 22, 60 adjacentes à chaque bord 68 constituent des moyens de fixation de ce bord au support. Le bord 68 est destiné à être inséré entre les deux premières portions 50a et 60a pour être pincé entre celles-ci et retenu par les reliefs 64. La première portion 50a de la première pièce d'assemblage 22 est plus fortement inclinée par rapport à la face latérale 20 de l'âme que le bord 68 associé. Elle constitue une surface de guidage adaptée à guider le bord 68 depuis une position voisine des moyens de fixation jusqu'à ceux-ci, le panneau 25 étant fixé au support par encastrement au moyen d'un déplacement relatif du support par rapport au panneau 25 suivant une direction perpendiculaire à la paroi 66 du panneau. Une fois le panneau 25 fixé au support, la paroi 66 s'étend parallèlement et à distance de la face avant 15 de l'âme qu'elle recouvre. Lors de ce guidage, les deux bords 68 s'éloignent l'un de l'autre. Dans cette position, la première pièce d'assemblage 22 s'étend à l'intérieur de l'élément de façade et la deuxième pièce d'assemblage 60 s'étend à l'extérieur de l'élément de façade. The two connecting pieces 22, 60 adjacent to each edge 68 constitute means for fixing this edge to support. The edge 68 is intended to be inserted between the first two portions 50a and 60a to be pinched between them and retained by the reliefs 64. The first portion 50a of the first assembly part 22 is more strongly inclined with respect to the face lateral 20 of the core than the associated edge 68. She constitutes a guide surface adapted to guide the edge 68 from a position close to the means of fixing to these, the panel 25 being fixed to the support by embedding by means of a displacement relative of the support relative to the panel 25 according to a direction perpendicular to the wall 66 of the panel. A once the panel 25 is fixed to the support, the wall 66 extends parallel and at a distance from the front face 15 of the core that it covers. During this guidance, the two edges 68 move away from each other. In this position, the first connecting piece 22 extends inside of the facade element and the second assembly part 60 extends outside the facade element.

On peut renforcer la fixation des bords 68 aux moyens de fixation en fixant chaque bord 68 et les premières portions 50a, 60a, par exemple au moyen de vis ou de rivets d'axe 80 les traversant de part en part et régulièrement espacés le long des profilés.We can strengthen the fixing of edges 68 to fixing means by fixing each edge 68 and the first portions 50a, 60a, for example by means of screws or of rivets of axis 80 crossing them right through and regularly spaced along the profiles.

Chaque élément de façade comporte un joint de recouvrement profilé 72 en caoutchouc synthétique fixé à la deuxième pièce d'assemblage 60 au voisinage de la portion médiane 60b et présentant une lèvre généralement plane s'étendant vers l'extérieur de l'élément de façade, parallèlement à la paroi 66.Each facade element has a joint of profile cover 72 in synthetic rubber attached to the second assembly part 60 in the vicinity of the middle portion 60b and generally having a lip plane extending outward from the element of facade, parallel to the wall 66.

L'ensemble comprend en outre un joint de liaison profilé 74 ayant un profil en forme de "V" dans lequel chaque branche du "V" est prolongée par une patte latérale profilée 76. Lorsque deux éléments de façade sont disposés dans un même plan en étant adjacents avec leurs deuxièmes pièces d'assemblage 60 en regard et parallèles l'une à l'autre, le joint de liaison 74 est adapté à être fixé aux deux deuxièmes pièces d'assemblage 60 par ses deux pattes latérales 76, au voisinage des branches arrière 54. La pointe du "V" s'étend alors en direction des joints de recouvrement 72.The set also includes a connecting joint profile 74 having a "V" shaped profile in which each branch of the "V" is extended by a leg profiled lateral 76. When two facade elements are arranged in the same plane by being adjacent with their second assembly parts 60 facing each other and parallel to each other, the connecting joint 74 is suitable to be fixed to the two second pieces assembly 60 by its two lateral legs 76, at neighborhood of the rear branches 54. The point of the "V" then extends towards the overlap joints 72.

Dans cette position, les deux joints de recouvrement 72 viennent en contact et en appui l'un contre l'autre de manière à interdire des passages de projection d'eau entre les deux éléments de façade suivant une direction perpendiculaire aux parois 66 des panneaux, depuis l'avant vers l'arrière des éléments de façade. Le joint de liaison 74 obture l'espace entre les deux éléments de façade et réalise une étanchéité à l'air suivant la même direction. Les joints d'interposition 62, à recouvrement 72 et de liaison 74 s'étendent sur toute la longueur des pièces d'assemblage 22 et 60. La deuxième pièce d'assemblage 60 est adaptée à recevoir le joint d'interposition 62, le joint à recouvrement 72 et le joint de liaison associé 74 avant fixation à la première pièce d'assemblage 22.In this position, the two joints of overlap 72 come into contact and support one against each other so as to prohibit passages from projection of water between the two facade elements in a direction perpendicular to the walls 66 of panels, from front to back of the elements of facade. The joint 74 closes the space between the two facade elements and provides a seal at air in the same direction. Joints interposition 62, overlapping 72 and connecting 74 extend over the entire length of the connecting parts 22 and 60. The second assembly part 60 is adapted to receive the interposition seal 62, the seal at cover 72 and the associated connection joint 74 before fixing to the first assembly part 22.

Dans cette position, les deux éléments de façade s'étendent à distance l'un de l'autre. Les bords 68 sont déformables de sorte que la paroi 66 est libre de se mouvoir parallèlement à elle-même par rapport au support associé lors d'une modification de la température du panneau 25, notamment lorsqu'elle se dilate. La fixation du panneau au support n'est pas altérée par cette déformation.In this position, the two facade elements extend at a distance from each other. The edges 68 are deformable so that the wall 66 is free to move parallel to itself with respect to the support associated when the temperature of the panel 25, especially when it expands. Fixation from the panel to the support is not altered by this deformation.

La première pièce d'assemblage 22 est par exemple en acier et s'étend à l'intérieur de l'élément de façade et au contact des équerres 30. La deuxième pièce d'assemblage 60 s'étend à l'extérieur de l'élément de façade et est en contact direct avec l'air extérieur ambiant. Elle est par exemple en aluminium. Le joint d'interposition 74 limite les transferts thermiques de la deuxième pièce d'assemblage 60 vers la première pièce d'assemblage 22.The first assembly part 22 is by example in steel and extends inside the element front and in contact with the 30 brackets. The second connecting piece 60 extends outside the element façade and is in direct contact with the outside air ambient. It is for example made of aluminum. Gasket interposition 74 limits heat transfers from the second connecting part 60 to the first part assembly 22.

La paroi 66 du panneau 25 peut avoir une forme, des reliefs et des couleurs très variées au gré des souhaits du concepteur de la façade. Le panneau 25 sera avantageusement une pièce thermoformée.The wall 66 of the panel 25 can have a shape, reliefs and colors very varied according to the wishes of the facade designer. Panel 25 will advantageously a thermoformed part.
