Description

La présente invention concerne une dalle, notamment une dalle de plafond, du type constitué d'un cadre sur lequel une toile est tendue.The present invention relates to a slab, in particular a ceiling tile, of the type consisting of a frame on which a canvas is stretched.

On connaít diverses dalles du type précité qui sont destinées à constituer un plafond mais qui peuvent également être utilisées pour former une paroi murale, et qui sont généralement obtenues en collant sur un cadre rigide une toile de matière plastique constituée la plupart du temps de chlorure de polyvinyle, que l'on chauffe afin de la dilater, de façon qu'après refroidissement, la rétraction de la toile sur le cadre assure la tension de celle-ci.We know various tiles of the above type which are intended to constitute a ceiling but which may also be used to form a wall, and which are generally obtained by sticking on a frame rigid a plastic canvas made up most of polyvinyl chloride time, which is heated so to expand it, so that after cooling, the retraction of the canvas on the frame ensures the tension of this one.

On sait par ailleurs que les forces de tension exercées par la toile sur le cadre ont tendance à provoquer un affaissement des côtés de celui-ci en direction du centre du cadre, qui donne à chacun des côtés de ce dernier une concavité orientée vers l'extérieur. C'est pourquoi, afin d'éviter les déformations des côtés du cadre, on donne à ceux-ci des sections droites importantes, si bien que le collage de la toile sur le cadre s'effectue sur une grande largeur. Or la plupart du temps ces dalles sont destinées à constituer de faux plafonds et sont ainsi disposées dans une structure support constituée d'un quadrillage réalisé à partir d'éléments profilés dont la section droite est en forme de T inversé. Dans ces conditions, chaque bord du cadre repose sur la face interne d'une branche latérale du profilé en T si bien que la zone de collage se trouve être plus large que celle de la branche du T et qu'elle devient dès lors visible, ce qui a pour effet de nuire grandement à l'esthétique.We also know that the tension forces exerted by the canvas on the frame tend to cause a sagging of the sides thereof towards the center of the frame, which gives each side of the latter an outward-facing concavity. That is why, in order to avoid deformations of the sides of the frame, we give to these important cross sections, so that the collage of the canvas on the frame is carried out on a large width. Most of the time, these tiles are intended for constitute false ceilings and are thus arranged in a support structure consisting of a grid produced at from profiled elements whose cross section is in inverted T shape. Under these conditions, each edge of the frame rests on the internal face of a lateral branch of the T-shaped so that the bonding area happens to be wider than that of the T branch and that it becomes therefore visible, which has the effect of greatly harming aesthetics.

On a proposé dans la demande de brevet FR-A-2.751.682 de remédier à cet inconvénient en proposant de réaliser une dalle de plafond dont le cadre est à la fois mince et indéformable. A cet effet, le cadre comportait des moyens aptes à réaliser une force de précontrainte dirigée de l'intérieur vers l'extérieur du cadre de façon à compenser la déformation due à la tension de la toile. Une telle réalisation est cependant complexe et onéreuse à mettre en oeuvre.It has been proposed in patent application FR-A-2,751,682 to remedy this drawback by proposing to carry out a ceiling tile with a frame that is both thin and undeformable. To this end, the framework included means able to achieve a directed prestressing force of inside to outside of the frame to compensate the deformation due to the tension of the fabric. Such a realization is however complex and expensive to set up artwork.

On sait enfin que les dalles de plafond sont parfois constituées de dalles pleines, habituellement formées d'un matériau isolant, tel que la laine de verre, la laine de roche, le polystyrène expansé etc... Lorsque de tels plafonds sont usagés, ils présentent de nombreux défauts sur le plan esthétique tout en conservant cependant l'essentiel de leurs qualités sur le plan de l'isolation phonique et thermique. Dans la pratique cependant on est contraint de remplacer l'ensemble de ces dalles. Un tel remplacement conduit ainsi à jeter des éléments qui conservent encore de bonnes qualités quant à l'absorption phonique et à l'isolation thermique. De plus, la destruction de ces dalles contribue d'une part à détériorer l'environnement en raison de la pollution qu'elle génère et d'autre part représente une perte sur le plan de la consommation d'énergie.We finally know that the ceiling tiles are sometimes made up of solid slabs, usually made of a insulating material, such as glass wool, wool rock, expanded polystyrene etc ... When such ceilings are worn, they have many defects aesthetically while retaining however most of their qualities in terms of insulation phonic and thermal. In practice, however, we are forced to replace all of these slabs. Such replacement thus leads to throwing away items which still retain good absorption qualities soundproofing and thermal insulation. In addition, the destruction of these slabs contributes on the one hand to deteriorate the environment because of the pollution it generates and on the other hand represents a loss in terms of energy consumption.

La présente invention a pour objet de proposer des dalles permettant notamment d'assurer la rénovation sur le plan esthétique de tels plafonds tout en conservant, voire en améliorant les qualités d'absorption phonique et d'isolation thermique procurées par les dalles anciennes, puisque l'invention favorise la disposition des nouvelles dalles sous les dalles anciennes. On satisfait ainsi aux critères de qualité à la fois sur le plan esthétique et sur le plan de l'isolation.The object of the present invention is to provide slabs used in particular to ensure renovation on the aesthetic level of such ceilings while retaining or even improving the sound absorption qualities and thermal insulation provided by old tiles, since the invention favors the disposition of news tiles under the old tiles. We thus meet the quality criteria both aesthetically and the insulation plan.

La présente invention a ainsi pour objet une dalle, notamment de plafond, du type constituée d'un cadre et d'une toile tendue sur celui-ci, dans laquelle chacun des cotés du cadre est formé d'un élément profilé comportant une paroi supérieure et une paroi latérale, et au moins une paroi de rigidification reliant les deux premières, de façon que l'élément profilé forme un caisson, caractérisée en ce que la base de chaque élément profilé est d'une faible largeur voisine de l'épaisseur de la paroi latérale de cet élément.The present invention thus relates to a slab, including ceiling, of the type consisting of a frame and of a canvas stretched over it, in which each of sides of the frame is formed of a profiled element comprising an upper wall and a side wall, and at least one stiffening wall connecting the first two, of so that the profiled element forms a box, characterized in that the base of each profiled element is of a narrow width close to the thickness of the side wall of this element.

Le cadre de la dalle suivant l'invention pourra être constitué d'éléments longitudinaux formant caisson qui sont assemblés entre eux.The frame of the slab according to the invention may be made up of longitudinal elements forming a box which are assembled together.

Dans un mode de mise en oeuvre préférentiel de l'invention cet assemblage des éléments longitudinaux pourra être effectué au moyen d'éléments rigides, par exemple en forme d'équerre, dont les branches respectives sont solidarisées desdits éléments longitudinaux. Pour réaliser cette solidarisation les éléments en équerre pourront prendre place dans des logements longitudinaux prévus à la base desdits éléments, au voisinage de la zone de fixation de la toile.In a preferred embodiment of the invention this assembly of longitudinal elements may be carried out by rigid elements, by square-shaped example, the respective branches of which are secured to said longitudinal elements. For realize this joining the square elements can take place in longitudinal housing provided at the base of said elements, in the vicinity of the area fixing the canvas.

Afin de favoriser la solidarisation, les logements longitudinaux auront au moins une dimension légèrement inférieure à celle des branches de l'élément en équerre, de façon à permettre une mise place à force des branches dans l'évidement. Dans une variante, les parois internes de l'évidement seront pourvues de picots déformables dont la hauteur sera telle que la distance séparant les picots appartenant à deux faces opposées de cet évidement soit légèrement inférieure à la dimension correspondante de la branche de l'élément en équerre prenant place dans ledit évidemment, de façon à permettre un assemblage à force. Par ailleurs afin de favoriser l'extrusion des éléments longitudinaux, l'évidement pourra comporter une rainure longitudinale débouchant à l'intérieur de l'élément longitudinal formant caisson.In order to promote solidarity, housing longitudinal will have at least one dimension slightly lower than that of the branches of the angled element, so as to allow forcing of the branches in the recess. Alternatively, the internal walls of the recess will be provided with deformable pins whose height will be such that the distance between the pins belonging to two opposite faces of this recess either slightly smaller than the corresponding dimension of the branch of the angled element taking place in said obviously, so as to allow assembly by force. Furthermore, in order to favor the extrusion of longitudinal elements, the recess may include a longitudinal groove opening inside the element longitudinal forming box.

La présente invention a également pour objet une installation comprenant des moyens de maintien de dalles constitués d'éléments support profilés à section droite en forme de T inversé, dans laquelle les dalles viennent en appui sur les branches horizontales des profilés en T, la dalle étant constituée d'un cadre et d'une toile tendue sur celui-ci, chacun des côtés du cadre étant formé d'un élément profilé comportant une paroi supérieure et une paroi latérale, et au moins une paroi de rigidification reliant les deux premières, de façon que l'élément profilé forme un caisson, caractérisée en ce que la base de chaque élément profilé est d'une largeur inférieure à celle des branches horizontales du profilé en T.The present invention also relates to a installation comprising means for holding slabs consisting of support elements profiled in cross section in inverted T shape, in which the slabs come in support on the horizontal branches of the T-sections, the slab consisting of a frame and a canvas stretched over this one, each side of the frame being formed of a profiled element comprising an upper wall and a side wall, and at least one stiffening wall connecting the first two, so that the profiled element forms a box, characterized in that the base of each profiled element has a width less than that of horizontal branches of the T-profile

On décrira ci-après, à titre d'exemples non limitatifs diverses formes d'exécution de la présente invention, en référence aux dessins annexés sur lesquels :There will be described below, by way of nonlimiting examples. various embodiments of the present invention, in reference to the accompanying drawings in which:

La figure 1 est une vue en coupe verticale d'un plafond équipé de dalles de plafond suivant l'état antérieur de la technique.Figure 1 is a vertical sectional view of a ceiling fitted with ceiling tiles according to condition prior art.

La figure 2 est une vue en coupe verticale d'un plafond pourvu de dalles suivant l'invention, qui sont disposées en combinaison de dalles suivant l'état antérieur de la technique.Figure 2 is a vertical sectional view of a ceiling provided with tiles according to the invention, which are arranged in combination of tiles according to the previous state of technique.

La figure 5 est une vue en coupe verticale partielle montrant un détail de mise en oeuvre des moyens de réception des dalles suivant l'invention.Figure 5 is a partial vertical sectional view showing a detail of implementation of the means of reception of the tiles according to the invention.

La figure 6 est une vue en coupe partielle en plan d'une dalle suivant l'invention montrant le mode d'assemblage de celle-ci.Figure 6 is a partial sectional plan view of a slab according to the invention showing the mode assembly thereof.

Les figures 7 à 9 sont des vues en coupe verticale partielle de variantes de mise en oeuvre d'une dalle de plafond suivant l'invention.Figures 7 to 9 are vertical section views partial of implementation variants of a slab of ceiling according to the invention.

Ainsi que représenté sur la figure 1, les dalles de plafond 1' de l'état antérieur de la technique sont habituellement maintenues à une distance d'un plafond 3 de la pièce au moyen de tirants 5 réglables en hauteur qui assurent le maintien d'éléments profilés longitudinaux 6 de section droite en forme de T inversé et qui sont disposés parallèlement, de façon à former des rangées dont l'écartement est égal à l'une des dimensions de la dalle 1. L'installation comprend également des éléments transversaux 7, qui sont disposés sur ceux-ci et qui sont écartés entre eux en fonction de l'autre dimension de la dalle 1' de façon à former un quadrillage. Comme représenté sur la figure 1, la dalle de plafond 1', qui est habituellement de forme carrée ou rectangulaire, et qui est constituée d'un matériau isolant tel que de la laine de roche ou du polystyrène expansé, vient prendre place dans le quadrillage formé par les éléments longitudinaux 6 et les éléments transversaux 7, de façon à prendre appui sur les branches latérales à profil en T de ces éléments.As shown in Figure 1, the slabs of 1 'ceiling of the prior art are usually kept at a distance of a ceiling 3 of the part by means of tie rods 5 adjustable in height which ensure the maintenance of longitudinal profiled elements 6 of inverted T-shaped cross section which are arranged in parallel, so as to form rows of which the spacing is equal to one of the dimensions of the slab 1. The installation also includes transverse elements 7, which are arranged thereon and which are spaced between them according to the other dimension of the slab 1 'of so as to form a grid. As shown in the Figure 1, the ceiling tile 1 ', which is usually square or rectangular shape, and which consists of a insulating material such as rock wool or expanded polystyrene, comes to take place in the grid formed by the longitudinal elements 6 and the transverse elements 7, so as to rest on the T-shaped side arms of these elements.

La dalle de plafond 1 suivant l'invention, qui est représentée sur les figures 2 et 3, est constituée d'une part d'un cadre 8, qui est formé ainsi que décrit ci-après, et d'une toile 9 qui est tendue et collée à la base de celui-ci.The ceiling tile 1 according to the invention, which is shown in Figures 2 and 3, consists of a part of a frame 8, which is formed as described below, and a canvas 9 which is stretched and glued to the base of this one.

Le cadre 8 formant l'ossature de la dalle 1 est constitué à partir d'éléments profilés 10 en chlorure de polyvinyle, dont la section droite est représentée en détails sur la figure 3, et qui sont fixés entre eux par exemple par collage. La section droite des éléments 10 est ainsi constituée de deux ailes perpendiculaires, à savoir une aile supérieure 10a et une aile latérale 10b qui sont réunies par une aile de rigidification 10c qui s'étend de la partie extrême interne de l'aile 10a à une zone distante d'une valeur e de la partie extrême inférieure de l'aile lOb. On forme donc un caisson qui présente l'avantage de posséder une grande rigidité.The frame 8 forming the framework of the slab 1 is made from profiled elements 10 of polyvinyl chloride, the cross section of which is shown in detail in FIG. 3, and which are fixed to each other for example by gluing. The cross section of the elements 10 thus consists of two perpendicular wings, namely an upper wing 10a and a lateral wing 10b which are joined by a stiffening wing 10c which extends from the inner end of the wing 10a to a zone distant by a value e from the lower extreme part of the wing lOb. A box is therefore formed which has the advantage of having great rigidity.

La toile 9, qui est également constituée préférentiellement de chlorure de polyvinyle et qui forme la partie visible de la dalle, est fixée notamment par collage, par soudure haute fréquence, ou par tout autre moyen, sur la base inférieure 10d de l'élément 10. On notera qu'il est particulièrement intéressant que l'élément profilé 10 et la toile 9 soient constitués d'un même matériau, notamment du chlorure de polyvinyle, cette identité de nature permettant leur solidarisation par des moyens de type soudure haute fréquence ou même soudure par chauffage. Cette base 10d a été hachurée sur la figure 4 afin de mieux la définir. Préférentiellement, la largeur de la base 10d des éléments 10 est inférieure à la largeur d'une branche horizontale 6a de l'élément en T 6 sur laquelle elle prend appui. De cette façon la zone de fixation de la toile 9 sur le cadre 8 qui présente habituellement un état de surface différent du reste de la surface centrale du cadre se trouve masquée aux yeux de l'utilisateur.Canvas 9, which also consists preferably polyvinyl chloride and which forms the visible part of the slab, is fixed in particular by bonding, by high frequency welding, or by any other medium, on the lower base 10d of element 10. On note that it is particularly interesting that the element profile 10 and the fabric 9 are made up of the same material, especially polyvinyl chloride, this identity of nature allowing their solidarity by high frequency welding or even welding by means heater. This base 10d has been hatched in FIG. 4 to better define it. Preferably, the width of the base 10d of the elements 10 is less than the width of a horizontal branch 6a of the element in T 6 on which it is supported. In this way the area of fixing of the canvas 9 on the frame 8 which has usually a different surface finish from the rest of the central surface of the frame is hidden from the eyes of the user.

Par ailleurs, le fait que la toile 9 soit fixée sur une zone 10d dont la largeur est réduite, facilite l'opération de fixation, que celle-ci s'effectue par collage ou par soudure à chaud ou à haute fréquence.Furthermore, the fact that the fabric 9 is fixed to an area 10d whose width is reduced, facilitates the fixing operation, that this is done by bonding or hot welding or high frequency.

Dans le cas d'un collage, l'opération d'application de la colle sera facilitée dans la mesure où on évite, de façon simple, tout débordement de celle-ci en dehors de la zone 10d destinée à la fixation de la toile.In the case of bonding, the operation of applying the glue will be facilitated insofar as it avoids, simple way, any overflow of it outside the zone 10d intended for fixing the fabric.

La section droite des éléments 10 constituant le cadre 8 de la dalle 1 est particulièrement intéressante en ce qu'elle présente une rigidité, notamment en raison de sa forme en caisson en raison de la présence de l'élément 10c, qui lui évite de se déformer sous l'effet de la force de la tension exercée par la toile 9.The cross section of the elements 10 constituting the frame 8 of slab 1 is particularly interesting in that that it has rigidity, in particular because of its box shape due to the presence of element 10c, which prevents it from deforming under the effect of the force of the tension exerted by the fabric 9.

Dans un mode de mise en oeuvre de l'invention, représenté sur les figures 6, 8 et 9, les différents éléments constituant le cadre 8 ne sont pas assemblés de façon définitive par collage ou par soudure mais à l'aide d'éléments métalliques 12 en forme d'équerre. Chacun de ces éléments 12 prend place dans un logement 14 de section droite rectangulaire qui est prévu dans une zone proche du point de rencontre des ailes 10b et 10c, c'est-à-dire dans une zone où les contraintes exercées par la toile 9 sont les plus importantes.In one embodiment of the invention, shown in Figures 6, 8 and 9, the different elements constituting the frame 8 are not assembled from definitively by gluing or welding but using of metal elements 12 in the form of a square. Each of these elements 12 takes place in a housing 14 of section rectangular right which is provided in an area close to the meeting point of wings 10b and 10c, that is to say in an area where the stresses exerted by the fabric 9 are the most important.

Préférentiellement les faces internes de ce logement 14 seront pourvues de picots 16 formant surépaisseur, dont la déformation assurera un frottement contrôlé établissant une solidarisation efficace des éléments 10 avec les équerres 12. Pour ce faire la largeur et la hauteur de la section droite de l'élément en équerre 12 seront légèrement supérieures à la distance séparant aussi bien en largeur que en hauteur les picots 16 de deux parois opposées. Bien entendu, à l'inverse, on pourra également disposer les picots 16 sur les éléments en équerre 12.Preferably the internal faces of this housing 14 will be provided with pins 16 forming additional thickness, of which the deformation will ensure a controlled friction establishing effective joining of the elements 10 with the brackets 12. To do this the width and height of the cross section of the angled element 12 will be slightly greater than the distance separating both in width that in height the pins 16 of two opposite walls. Well of course, conversely, we can also arrange the pins 16 on the square elements 12.

Les éléments constitutifs du cadre 8 pourront être formés notamment par moulage par injection ou par moulage par extrusion. Afin de faciliter ce dernier mode de mise en oeuvre, la paroi supérieure du logement 14 recevant l'élément en équerre 12 sera pourvue d'une rainure longitudinale verticale 18.The constituent elements of frame 8 may be formed in particular by injection molding or by molding by extrusion. In order to facilitate this last mode of implementation work, the upper wall of the housing 14 receiving the angled element 12 will be provided with a groove vertical longitudinal 18.

Ainsi que représenté sur la figure 5, on pourra recouvrir les éléments profilés longitudinaux 6 et transversaux 7 de l'élément à section droite en forme de T, d'une gaine en matière plastique 19, ce qui d'une part permettra de modifier et contrôler l'esthétique de ce profilé et d'autre part protégera la toile, dans la zone par laquelle elle vient en contact avec cet élément, des atteintes susceptibles d'être réalisées par l'élément support, telles que les accrochages, etc...As shown in Figure 5, we can cover the longitudinal profiled elements 6 and transverse 7 of the T-shaped cross-section element, of a plastic sheath 19, which on the one hand will modify and control the aesthetics of this profiled and on the other hand will protect the canvas, in the area by which it comes into contact with this element, damage likely to be achieved by the element support, such as hanging, etc ...

On pourrait bien entendu, ainsi que représenté sur la figure 7, réaliser l'élément allongé 10 constituant le cadre 8 avec une section droite de forme rectangulaire de façon à constituer également un élément en caisson.We could of course, as shown on the Figure 7, make the elongated element 10 constituting the frame 8 with a rectangular cross section of so as to also constitute a box element.

On pourrait également assurer l'assemblage de deux éléments longitudinaux consécutifs à l'aide de deux éléments en équerre.We could also ensure the assembly of two consecutive longitudinal elements using two square elements.
