Description

Domaine techniqueTechnical area

La présente invention concerne les dalles de fausse paroi, notamment les dalles de faux plafond et plus particulièrement les dalles constituées d'un cadre formé de lisses aboutées sur lequel est tendue une toile.The present invention relates to false-wall slabs, including false ceiling slabs and more particularly slabs consisting of a frame formed of abutting slats on which is stretched a canvas.

Technique antérieurePrior art

De nos jours, il est connu de créer des fausses parois, du type faux plafond notamment, à partir de dalles. Les dalles du type précité sont habituellement obtenues en fixant, notamment par collage, sur un cadre, généralement obtenu préalablement par assemblage de profilés en aluminium, une nappe constituée d'une toile extensible de matière plastique, habituellement en chlorure de polyvinyle (PVC), que l'on chauffe afin de la dilater, si bien qu'après refroidissement, la rétraction de la toile sur le cadre assure la tension de celle-ci. On sait par ailleurs que les dalles de plafond précédemment mentionnées sont la plupart du temps disposées dans une structure supportée par un plafond et qui est constituée d'un quadrillage réalisé à partir d'éléments profilés dont la section droite est préférentiellement en forme de T inversé, si bien que chacun des bords de la dalle de plafond repose par sa périphérie sur la face interne d'une branche latérale du profilé en forme de T.Nowadays, it is known to create false walls, including false ceiling type, from slabs. Slabs of the aforementioned type are usually obtained by fixing, especially by gluing, on a frame, generally previously obtained by assembling aluminum profiles, a sheet consisting of an extensible plastic web, usually made of polyvinyl chloride (PVC), heated to dilate it, so that after cooling, the retraction of the fabric on the frame ensures the tension thereof. It is also known that the above-mentioned ceiling slabs are most of the time arranged in a structure supported by a ceiling and which consists of a grid made from profiled elements whose cross-section is preferably in inverted T-shape. so that each edge of the ceiling tile rests at its periphery on the inner face of a side branch of the T-shaped profile.

Une difficulté importante dans la réalisation de ces dalles est que le cadre se déforme, par suite de la fixation sous tension de la toile sur ce cadre, en raison de la légèreté de la structure dudit cadres utilisé, et donc de sa résistance à la flexion. Diverses solutions ont déjà été proposées dans l'art antérieur pour résoudre ce problème. En effet, il a été proposé de prévoir des moyens exerçant une précontrainte dirigée de l'intérieur vers l'extérieur du cadre. Toutefois, de tels moyens, s'ils sont efficaces, sont néanmoins coûteux tout au moins au niveau de la mise en oeuvre nécessaire à leur réalisation.A major difficulty in the realization of these slabs is that the frame is deformed, as a result of the attachment under tension of the fabric on this frame, because of the lightness of the structure of said frame used, and therefore of its resistance to bending . Various solutions have already been proposed in the prior art to solve this problem. problem. Indeed, it has been proposed to provide means exerting a prestress directed from the inside to the outside of the frame. However, such means, if they are effective, are nevertheless expensive at least at the level of the implementation necessary for their realization.

De plus, on connaît également une dalle de plafond dont les profilés formant le cadre sont soit pourvus d'ailes de renfort soit en forme de caisson parfaitement apte à résister aux forces de traction de la toile. Toutefois, ces profilés sont relativement larges, en particulier lorsque les dalles sont de grande surface, ce qui impose d'avoir des éléments supports en forme de T larges afin de ne pas laisser apparaître, d'une part, la zone de fixation de la toile et, d'autre part, l'ombre projetée desdits profilés en cas de dalles rétro-éclairées. Ces éléments supports en forme de T larges rendent particulièrement inesthétiques la fausse paroi ainsi constituée.In addition, there is also known a ceiling tile whose profiles forming the frame are either provided with reinforcing wings or box-shaped perfectly able to withstand the tensile forces of the fabric. However, these profiles are relatively wide, especially when the slabs are large, which requires having T-shaped support members large so as not to show, on the one hand, the fixing area of the canvas and, on the other hand, the projected shadow of said profiles in case of backlit slabs. These support elements T-shaped wide make particularly unsightly the false wall thus formed.

Enfin, dans les dalles de l'art antérieur, la nappe est classiquement collée sur les profilés constituant le cadre. Ce mode de fixation n'est pas facile à mettre en oeuvre et ne permet pas de retirer aisément la nappe dudit cadre pour adapter la nappe au changement d'ambiance du local dans lequel sont installées lesdites dalles.Finally, in the slabs of the prior art, the sheet is conventionally bonded to the profiles constituting the frame. This method of attachment is not easy to implement and does not allow easy removal of the sheet of said frame to adapt the sheet to change the atmosphere of the room in which are installed said slabs.

FR 2 952 087 décrit une dalle pour fausse paroi selon le préambule de la revendication 1. FR 2,952,087 discloses a slab for false wall according to the preamble of claim 1.

Exposé de l'inventionPresentation of the invention

L'objet de la présente invention est de proposer une alternative aux dalles de fausse paroi existantes permettant de pallier les inconvénients précités. Ces dalles selon l'invention sont faciles à mettre en oeuvre, sans collage, résistantes, pérennes et permettent une utilisation rétro-éclairée sans faire apparaître l'ombre projetée des profilés constituant leur cadre.The object of the present invention is to provide an alternative to existing false-wall slabs to overcome the aforementioned drawbacks. These slabs according to the invention are easy to implement, without gluing, resistant, durable and allow backlit use without showing the projected shadow of the profiles constituting their frame.

La présente invention a ainsi pour objet une dalle pour fausse paroi, notamment du type faux plafond, comprenant un cadre réalisé à partir de profilés aboutés et une nappe fixée tendue sur ledit cadre, chaque profilé comportant une paroi supérieure, une paroi latérale issue de l'une des extrémités de ladite paroi supérieure et une paroi de renfort réunissant les extrémités libres des parois supérieure et latérale de manière à ce que chaque profilé ait une section transversale en forme générale de triangle, ladite dalle étant remarquable en ce qu'elle comporte un clip de fixation distinct de la nappe et en ce que la paroi supérieure est pourvue d'au moins un logement apte à coopérer de façon amovible avec ledit clip de fixation pour fixer la nappe tendue sur ledit cadre en la maintenant serrée dans ledit logement par le clip de fixation.The present invention thus relates to a slab for a false wall, in particular of the false ceiling type, comprising a frame made from abutting profiles and a fixed sheet stretched on said frame, each section comprising an upper wall, a side wall coming from one of the ends of said upper wall and a reinforcing wall joining the free ends of the upper and lateral walls so that each section has a cross section in the general shape of a triangle, said slab being remarkable in that it comprises a fastening clip distinct from the sheet and in that the upper wall is provided with at least one housing adapted to cooperate removably with said fixing clip for fixing the sheet stretched on said frame by keeping it tight in said housing by the fastening clip.

Une telle configuration offre de nombreux avantages. En particulier, on comprend bien que le mode de fixation est résistant et pérenne et qu'on n'a plus à craindre que la largeur de la zone de collage de la nappe sur ledit cadre soit insuffisante pour que le collage résiste aux tensions de la nappe. De plus, cette configuration permet de changer très facilement et sans endommagement la nappe de la dalle.Such a configuration offers many advantages. In particular, it is well understood that the method of attachment is strong and durable and it is no longer to be feared that the width of the bonding zone of the sheet on said frame is insufficient for the bonding to withstand the stresses of the tablecloth. In addition, this configuration makes it possible to very easily and without damage change the sheet of the slab.

De manière avantageuse, chaque profilé a une section transversale en forme générale de triangle rectangle.Advantageously, each section has a cross section in the general shape of a right triangle.

Selon un mode de réalisation préféré, la paroi latérale de chaque profilé est munie d'un évidement prévu au moins dans une zone proche du point de rencontre des parois latérale et de renfort et apte à recevoir des éléments de liaison en forme d'équerre pour constituer ledit cadre.According to a preferred embodiment, the lateral wall of each profile is provided with a recess provided at least in an area near the meeting point of the side and reinforcement walls and adapted to receive wedge-shaped connecting elements for constitute the said framework.

Lesdits évidements ont de préférence au moins une dimension légèrement inférieure à celle des branches de l'élément de liaison en forme d'équerre, de façon à permettre une mise en place à force desdites branches dans lesdits évidements.Said recesses preferably have at least one dimension slightly smaller than that of the branches of the bracket-shaped connecting element, so as to allow these branches to be force-fitted into said recesses.

Selon un mode de réalisation préféré, les parois internes de dudit évidement sont pourvues de picots déformables dont la hauteur est telle que la distance séparant les picots de deux faces opposées de cet évidement soit légèrement inférieure à la dimension correspondante de la branche de l'élément de liaison prenant place dans ledit évidement, de façon à permettre un assemblage à force.According to a preferred embodiment, the inner walls of said recess are provided with deformable pins whose height is such that the distance between the pins of two opposite faces of this recess is slightly smaller than the corresponding dimension of the element's limb. linkage taking place in said recess, so as to allow a forced assembly.

Avantageusement, ledit évidement est réalisé sur toute la longueur du chaque profilé associé et en ce que la paroi latérale dudit profilé est pourvue d'une rainure longitudinale débouchant dans ledit évidement.Advantageously, said recess is made along the entire length of each associated section and in that the side wall of said profile is provided with a longitudinal groove opening into said recess.

Description sommaire des figuresBrief description of the figures

D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre d'une variante d'exécution d'une dalle de fausse paroi selon l'invention en référence aux figures annexées sur lesquelles :

  • la figure 1 est une section verticale d'une dalle pour fausse paroi selon l'invention ;
  • la figure 2 est une vue de détail d'un profilé du cadre de la dalle de la figure 1.
Other advantages and features will become more apparent from the following description of an alternative embodiment of a false wall slab according to the invention with reference to the appended figures in which:
  • the figure 1 is a vertical section of a slab for false wall according to the invention;
  • the figure 2 is a detail view of a profile of the frame of the slab of the figure 1 .

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

On décrira, dans ce mode d'exécution non limitatif, une dalle de fausse paroi horizontale du type faux plafond. Toutefois, la dalle selon l'invention pourra évidemment être utilisée pour constituer une fausse paroi verticale ou inclinée du type faux mur, les termes horizontal et vertical seront alors à adaptés.In this non-limiting embodiment, a false horizontal wall slab of the false ceiling type will be described. However, the slab according to the invention can obviously be used to form a false vertical wall or inclined false wall type, the horizontal and vertical terms will then be adapted.

Ainsi, on a représenté sur les figures 1 et 2 une dalle 1 pour fausse paroi, notamment du type faux plafond, comprenant un cadre 2 réalisé à partir de profilés 3 aboutés et une nappe 4 fixée tendue sur ledit cadre 2. La dalle 1 est disposée dans une structure constituée d'un quadrillage réalisé à partir d'éléments support 5 dont la section droite est préférentiellement en forme de T inversé, si bien que chacun des bords de la dalle 1 repose par sa périphérie sur la face interne d'une branche latérale de l'élément support 5 en forme de T.Thus, it has been shown on Figures 1 and 2 a slab 1 for a false wall, in particular of the false ceiling type, comprising a frame 2 made from 3 abutting sections 3 and a fixed sheet 4 stretched on said frame 2. slab 1 is arranged in a structure consisting of a grid made from support elements 5 whose cross section is preferably inverted T-shaped, so that each of the edges of the slab 1 rests by its periphery on the inner face of a lateral branch of the support element 5 in the form of a T.

Chaque profilé 3 comprend une paroi supérieure 31 sensiblement horizontale, une paroi latérale 32 issue de l'une des extrémités de ladite paroi supérieure 31 de préférence sensiblement perpendiculairement et une paroi de renfort 33 réunissant les deux parois supérieure et latérale 31, 32 et s'étendant de l'extrémité libre de la paroi supérieure 31 jusqu'à l'extrémité libre de la paroi latérale 32 de manière à ce que chaque profilé 3 ait une section transversale en forme générale de triangle rectangle.Each profile 3 comprises a substantially horizontal upper wall 31, a side wall 32 issuing from one of the ends of said upper wall 31 preferably substantially perpendicularly and a reinforcing wall 33 joining the two upper and lateral walls 31, 32 and extending from the free end of the upper wall 31 to the free end of the side wall 32 so that each section 3 has a generally rectangular cross-sectional shape.

On comprend bien que cette section permet à la fois de garantir une grande résistance aux efforts de flexion et de ne pas avoir d'ombre du profilé projetée sur la nappe 4 car la partie des profilés 3 du cadre 2 reposant sur les éléments support 5 ne dépassent de la branche latérale desdits éléments support 5 en forme de T.It is well understood that this section makes it possible both to guarantee a high resistance to the bending forces and to have no shadow of the profile projected on the ply 4 because the part of the profiles 3 of the frame 2 resting on the support elements 5 protrude from the side branch of said T-shaped support members 5.

Par ailleurs, la paroi latérale 32 de chaque profilé 3 est munie d'un évidement 34 de section droite rectangulaire destiné à recevoir des éléments de liaison non représentés en forme d'équerre. Chacun de ces éléments de liaison prend place dans un évidement 34 qui est prévu au moins dans une zone proche du point de rencontre des parois latérale et de renfort 32, 33, c'est-à-dire dans une zone où les contraintes exercées par la nappe 4 sont les plus importantes. Ces éléments de liaison assurent la liaison entre différents profilés 3 pour constituer le cadre 2 mais également le renfort mécanique des angles dudit cadre 2.Furthermore, the side wall 32 of each section 3 is provided with a recess 34 of rectangular cross-section for receiving non-represented connecting elements in the form of a square. Each of these connecting elements takes place in a recess 34 which is provided at least in an area near the meeting point of the side and reinforcement walls 32, 33, that is to say in an area where the stresses exerted by the tablecloth 4 are the most important. These connecting elements provide the connection between different profiles 3 to constitute the frame 2 but also the mechanical reinforcement of the corners of said frame 2.

Les évidements 34 ont au moins une dimension légèrement inférieure à celle des branches de l'élément de liaison en forme d'équerre, de façon à permettre une mise en place à force desdites branches dans lesdits évidements 34.The recesses 34 have at least a dimension slightly smaller than that of the branches of the bracket-shaped connecting element, so as to allow for force-fitting said branches into said recesses 34.

Dans un mode de réalisation préférée, les faces internes de cet évidement 34 seront pourvues de picots, non représentés, formant surépaisseur, dont la déformation assurera un frottement contrôlé établissant une solidarisation efficace des éléments de liaison avec chaque profilé 3. Pour ce faire la largeur et la hauteur de la section droite des éléments de liaison seront légèrement supérieures à la distance séparant aussi bien en largeur qu'en hauteur les picots de deux faces opposées de l'évidement 34. Bien entendu, à l'inverse, on pourra également disposer les picots sur les éléments de liaison en équerre.In a preferred embodiment, the internal faces of this recess 34 will be provided with pins, not shown, forming an excess thickness, the deformation of which will ensure a controlled friction establishing an effective joining of the connecting elements with each profile 3. To do this the width and the height of the cross section of the connecting elements will be slightly greater than the distance separating both the width and height of the pins of two opposite faces of the recess 34. Of course, conversely, it will also be possible the pins on the connecting elements at right angles.

Chaque profilé 3 est de préférence réalisé en alliage d'aluminium par extrusion. Par conséquent, afin de faciliter la mise en oeuvre de ce mode de réalisation, l'évidement 34 sera réalisé sur toute la longueur du chaque profilé 3 associé et la paroi latérale 32 dudit profilé 3 sera pourvue d'une rainure 35 longitudinale débouchant dans ledit évidement 34.Each profile 3 is preferably made of aluminum alloy by extrusion. Therefore, to facilitate the implementation of this embodiment, the recess 34 will be made along the entire length of each associated section 3 and the side wall 32 of said profile 3 will be provided with a longitudinal groove 35 opening into said recess 34.

La nappe 4 est constituée d'une toile 41 extensible de matière plastique, habituellement en chlorure de polyvinyle (PVC). Cette nappe 4 est fixée tendue sur le cadre 2 pour former la dalle 1 pour fausse paroi selon l'invention.The web 4 consists of an extensible fabric 41 of plastic, usually polyvinyl chloride (PVC). This sheet 4 is fixed stretched on the frame 2 to form the slab 1 for false wall according to the invention.

Pour cela, la paroi supérieure 31 de chaque profilé 3 est pourvue d'au moins un logement 36 apte à coopérer de façon amovible avec un clip de fixation 6. La nappe 4 est alors fixée sur ledit profilé 3 en étant maintenue serrée dans ledit logement 36 par le clip de fixation 6. En effet, on comprend bien que ce mode de fixation avec le clip de fixation 6 permet, d'une part de ne pas utiliser de colle et, d'autre part, de pouvoir changer aisément de nappe 4 sans l'endommager en retirant simplement ledit clip de fixation 6 du logement 36, comme représenté en pointillé sur la figure 2.For this, the upper wall 31 of each section 3 is provided with at least one housing 36 adapted to cooperate in a detachable manner with a fastening clip 6. The sheet 4 is then fixed on said section 3 being held tightly in said housing 36 by the fastening clip 6. Indeed, it is understood that this method of attachment with the fastening clip 6 allows, on the one hand, not to use glue and, on the other hand, to be able to easily change the sheet 4 without damaging it by simply removing said clip from fastening 6 of the housing 36, as shown in dotted line on the figure 2 .

Pour tendre la nappe 4 avant sa fixation, on pourra tirer à la main sur la nappe 4 en la chauffant de préférence pour, qu'après refroidissement, sa rétraction assure une parfaite tension.In order to tension the ply 4 before it is fastened, it is possible to pull the ply 4 by hand by heating it preferably so that, after cooling, its retraction ensures a perfect tension.

Possibilité d'application industriellePossibility of industrial application

Comme décrit précédemment, l'invention trouvera une application pour tout type de fausses parois de bâtiments industriels, mais aussi d'habitations particulières.As described above, the invention will find an application for all types of false walls of industrial buildings, but also special homes.

Enfin, il est clair que la présente invention ne se limite pas à la seule forme d'exécution de cette dalle 1 pour fausse paroi ; elle en embrasse, au contraire, toutes les variantes de réalisation et d'application respectant le même principe.Finally, it is clear that the present invention is not limited to the sole embodiment of this slab 1 for false wall; it embraces, on the contrary, all variants of implementation and application respecting the same principle.
