Description

DALLE DE PAROI FORMANT MIROIR ET PROCEDE  WALL SLAB FORMING MIRROR AND METHOD
DE REALISATION D'UNE TELLE DALLE  REALIZATION OF SUCH A SLAB
[001] L'invention concerne le domaine des dalles de paroi destinées notamment à former un plafond suspendu ou une paroi murale. [001] The invention relates to the field of wall tiles intended in particular to form a suspended ceiling or a wall wall.
[002] L'invention concerne plus particulièrement une dalle de paroi constituée d'un cadre et d'une toile tendue sur le cadre, ladite toile présentant une face à effet miroir. [002] The invention relates more particularly to a wall panel consisting of a frame and a canvas stretched over the frame, said fabric having a mirror effect face.
[003] De manière connu, les dalles de paroi pour plafond suspendu ou paroi murale sont formées d'une toile, constituée la plupart du temps de chlorure de polyvinyle (PVC), fixée sur un cadre rigide métallique. Afin de tendre la toile sur le cadre, il est en général procédé à son chauffage afin de la dilater, la toile se rétractant ensuite lors de son refroidissement, assurant ainsi sa tension sur le cadre. [003] In known manner, the wall tiles for suspended ceiling or wall are formed of a fabric, usually consisting of polyvinyl chloride (PVC), fixed on a rigid metal frame. In order to stretch the canvas on the frame, it is generally heated to expand, the canvas then retracts during its cooling, thus ensuring its tension on the frame.
[004] Face à une demande croissante de plafonds ou de parois murales décoratif(ve)s, il est répandu de revêtir les faces des dalles de paroi visibles depuis le local dans lequel elles sont installées, soit de peinture, soit d'un revêtement décoratif. Parmi les revêtements décoratifs mis en œuvre, sont proposés des revêtements à effet miroir. [004] Faced with a growing demand for ceilings or decorative wall walls, it is common to coat the faces of the wall tiles visible from the room in which they are installed, either of paint or of a coating decorative. Among the decorative coatings used, are proposed mirror effect coatings.
[005] Ces derniers présentent cependant l'inconvénient de conférer à la toile une certaine rigidité de sorte que la mise en tension de la toile sur le cadre est rendue plus difficile. Or, lorsqu'elle n'est pas suffisamment tendue, l'image reflétée sur la toile présente des distorsions. Par ailleurs, les défauts et déformations présents sur la surface de la toile sont d'autant plus visible à l'œil nuque que la toile n'est pas bien tendue, nuisant alors à l'effet miroir recherché. [005] However, the latter have the disadvantage of giving the fabric a certain rigidity so that the tension of the canvas on the frame is made more difficult. However, when it is not sufficiently taut, the image reflected on the canvas presents distortions. Moreover, the defects and deformations present on the surface of the fabric are all the more visible to the nape eye that the fabric is not well tensioned, thus detracting from the desired mirror effect.
[006] L'invention vise à remédier à ces problèmes en proposant une dalle de paroi à effet miroir présentant une tension optimale de la toile sur le cadre. [007] A cet effet, et selon un premier aspect, l'invention propose une dalle de paroi constituée d'un cadre présentant au moins un bord latéral et d'une toile présentant une face avant réfléchissante et une face arrière, la dalle de paroi comprenant en outre au moins un méplat de renfort de tension disposés entre ladite toile et le bord latéral du cadre. [006] The invention aims to remedy these problems by proposing a mirror wall slab having an optimal tension of the fabric on the frame. [007] For this purpose, and according to a first aspect, the invention proposes a wall slab consisting of a frame having at least one side edge and a fabric having a reflective front face and a rear face, the slab of wall further comprising at least one tension reinforcing flat disposed between said web and the side edge of the frame.
[008] Par « face avant», on désigne la face de la toile visible de l'intérieur du local dans lequel la dalle de paroi est installée, et inversement, par « face arrière», la face de la toile non visible de l'intérieur du local dans lequel la dalle de paroi est installée. [009] On désigne également par « méplat » une pièce ayant un profil de section rectangulaire et de faible épaisseur. [008] "Front face" means the face of the visible web from the interior of the room in which the wall panel is installed, and conversely, by "rear face", the face of the non-visible fabric of the inside the room in which the wall slab is installed. [009] Also denotes by "flat" a part having a profile of rectangular section and thin.
[0010] La présence de méplat(s) de renfort de tension permet d'assurer la mise sous tension de la toile sur le cadre. Par ailleurs, lorsque la toile est tendue sur le cadre, cette dernière exerce des forces de compression et de flexion sur le cadre. La présence de méplat(s) de renfort de tension permet alors de distribuer uniformément le long du ou des bords latéraux du cadre les forces ainsi exercées par la toile. The presence of flat (s) of tension reinforcement ensures the power of the canvas on the frame. Moreover, when the canvas is stretched on the frame, the latter exerts compression and bending forces on the frame. The presence of flattened (s) of tension reinforcement then allows to distribute uniformly along the side or edges of the frame the forces thus exerted by the fabric.
[0011] La dalle de paroi dont la tension de la toile est assurée du fait de la présence de méplat(s) de renfort présente ainsi une face avant réfléchissante plane en tout point, offrant ainsi en retour une image miroir dépourvue de distorsion. [0012] On désignera indifféremment par la suite le « méplat de renfort de tension », par « méplat de renfort » ou « méplat ». The wall slab whose tension of the fabric is ensured due to the presence of flattening (s) of reinforcement and has a flat reflective front face at any point, thus providing in return a mirror image devoid of distortion. We will designate indifferently thereafter the "flat reinforcement of tension", by "flattened reinforcement" or "flattened".
[0013] Avantageusement, le méplat de renfort présente une épaisseur supérieure à 0,5 millimètre. Advantageously, the reinforcing flat has a thickness greater than 0.5 millimeters.
[0014] Avantageusement, le méplat de renfort est fixé sur le bord latéral du cadre au moyen d'une première couche adhésive et sur la toile au moyen d'une deuxième couche adhésive, les première et deuxième couches adhésives étant située à une hauteur donnée de la toile. Advantageously, the reinforcing flat is fixed on the lateral edge of the frame by means of a first adhesive layer and on the fabric by means of a second adhesive layer, the first and second adhesive layers being located at a given height. some cobweb.
[0015] L'invention concerne également un procédé de réalisation d'une dalle de paroi comprenant un cadre présentant au moins un bord latéral et une toile présentant une face extérieure réfléchissante et une face intérieure, le procédé comprenant les étapes consistant à renforcer un portion de toile au moins à l'aide d'au moins un méplat de renfort de tension, le méplat de renfort étant agencé sur la toile de manière à présenter un bord longitudinal jointif au bords latéral du cadre lorsque le cadre est positionné sur la toile et replier et fixer la portion de toile renforcée sur le bord latéral du cadre. The invention also relates to a method of producing a wall slab comprising a frame having at least one side edge and a fabric having a reflective outer face and an inner face, the method comprising the steps of reinforcing a portion at least using at least one tension reinforcing flat, the reinforcing flat being arranged on the fabric so as to have an edge longitudinal border joined to the side edges of the frame when the frame is positioned on the fabric and fold and secure the reinforced fabric portion on the side edge of the frame.
[0016] Avantageusement, la face extérieure réfléchissante est revêtue d'un film de protection, de préférence pelable. [0017] Avantageusement, le méplat de renfort est fixé sur la toile au moyen d'une première couche adhésive appliquée sur une face du méplat de façon à réserver une zone longitudinale dépourvue d'adhésif, le méplat étant placé sur la toile de sorte que le bord longitudinal du méplat bordant la zone longitudinale dépourvue d'adhésif soit au contact de la zone longitudinale dépourvue d'adhésif (7) du bord latéral du cadre. [0018] Avantageusement, le méplat de renfort est fixé sur le bord latéral du cadre au moyen d'une deuxième couche adhésive appliquée sur le bord latéral du cadre de façon à réserver une zone longitudinale dépourvue d'adhésif. [0016] Advantageously, the reflective outer face is coated with a protective film, preferably peelable. Advantageously, the reinforcing flat is fixed on the fabric by means of a first adhesive layer applied on one face of the flat so as to reserve a longitudinal zone free of adhesive, the flat part being placed on the fabric so that the longitudinal edge of the flat part bordering the longitudinal zone without adhesive is in contact with the longitudinal zone without adhesive (7) of the lateral edge of the frame. Advantageously, the reinforcing flat is attached to the side edge of the frame by means of a second adhesive layer applied to the side edge of the frame so as to reserve a longitudinal area devoid of adhesive.
[0019] Avantageusement, la toile est découpée le long d'une ligne de découpe délimitée par le méplat de renfort et le cadre. [0020] Avantageusement, le procédé comporte une étape de chauffage de la toile une fois cette dernière tendue sur le cadre. Advantageously, the fabric is cut along a cutting line defined by the reinforcing flat and the frame. Advantageously, the method comprises a step of heating the fabric once the latter stretched on the frame.
[0021] D'autres objets et avantages de l'invention apparaîtront au cours de la description qui suit, faite en référence aux dessins annexés, dans lesquels : Other objects and advantages of the invention will become apparent from the following description, made with reference to the accompanying drawings, in which:
- la figure 1 représente une vue schématique en coupe d'une dalle de paroi selon l'invention ; - Figure 1 shows a schematic sectional view of a wall panel according to the invention;
- la figure 2 représente une vue de détail agrandie de la dalle de paroi de la figure 1 ; FIG. 2 represents an enlarged detail view of the wall slab of FIG. 1;
- les figures 3A à 3D représentent une illustration schématique des étapes de réalisation de la dalle de paroi de la figure 1 ; FIGS. 3A to 3D show a schematic illustration of the steps for producing the wall slab of FIG. 1;
- la figure 4 représente une vue en coupe du cadre de la dalle de paroi de la figure 3 A. [0022] En relation avec les figures 1 et 2, il est décrit une dalle de paroi 1 comprenant un cadre 2 de forme sensiblement parallélépipédique et une toile 3 montée tendue sur ledit cadre. - Figure 4 shows a sectional view of the frame of the wall plate of Figure 3 A. In connection with Figures 1 and 2, there is described a wall panel 1 comprising a frame 2 of substantially parallelepiped shape and a web 3 mounted on said frame.
[0023] Le cadre 2, de préférence métallique, est formé de quatre profilés 2a à 2d, de préférence en aluminium, présentant, en section, une forme d'équerre droite dont l'une des branches constitue un des bords latéraux 20a à 20d du cadre 2, l'autre branche constituant la face arrière de la dalle de paroi. The frame 2, preferably metal, is formed of four sections 2a to 2d, preferably aluminum, having, in section, a straight square shape of which one of the branches constitutes one of the side edges 20a to 20d frame 2, the other branch constituting the rear face of the wall slab.
[0024] La toile 3, avantageusement en polychlorure de vinyle (PVC), comporte une première face dite « face avant » 30 revêtue d'un matériau métallisé réfléchissant et d'une deuxième face dite « face arrière » 31. On définit les faces avant et arrière 30, 31 selon la position de la toile 3 par rapport au cadre 2. The fabric 3, advantageously made of polyvinyl chloride (PVC), comprises a first so-called "front face" 30 coated with a reflective metallized material and a second so-called "back face" 31. The faces are defined front and rear 30, 31 according to the position of the fabric 3 relative to the frame 2.
[0025] Selon l'invention, la toile 3 est fixée sur le cadre 2 par l'intermédiaire de méplats de renfort 4a à 4d. Plus particulièrement, la dalle de paroi 1 comporte quatre méplats 4a à 4d, chaque méplat étant disposé entre un bord latéral d'un des profilés 2a à 2d et la face interne d'un volet de toile replié sur le bord latéral en question. Comme on le verra plus loin, les méplats de renfort 4a à 4d sont agencés avec le cadre 2 et la toile 3 pour assurer la mise en tension de la toile sur le cadre. According to the invention, the fabric 3 is fixed on the frame 2 by means of reinforcing flats 4a to 4d. More particularly, the wall slab 1 comprises four flats 4a to 4d, each flats being disposed between a lateral edge of one of the profiles 2a to 2d and the inner face of a fabric flap folded over the lateral edge in question. As will be seen below, the reinforcing flats 4a to 4d are arranged with the frame 2 and the fabric 3 to ensure the tensioning of the fabric on the frame.
[0026] Les méplats se présentent chacun sous la forme d'une plaque allongée, de section rectangulaire et de faible épaisseur. Avantageusement, chaque méplat 4a à 4d présente avantageusement des dimensions identiques aux dimensions du bord latéral 20a, 20d associé du cadre 2. Il présente en outre une épaisseur supérieure à 0,5 millimètre. Selon un mode de réalisation préféré, les méplats 4a à 4d présentent une épaisseur sensiblement égale celle des branches des profilés constituant les bords latéraux du cadre. The flats are each in the form of an elongate plate, of rectangular section and of small thickness. Advantageously, each flat portion 4a to 4d advantageously has dimensions identical to the dimensions of the lateral edge 20a, 20d associated with the frame 2. It further has a thickness greater than 0.5 millimeter. According to a preferred embodiment, the flats 4a to 4d have a thickness substantially equal to that of the branches of the profiles constituting the lateral edges of the frame.
[0027] Comme représenté sur la figure 2, chaque méplat 4a à 4d est fixé par une première couche adhésive 6 sur la toile 2 et par une deuxième couche adhésive 5 sur un des bords latéraux 20a, 20d du cadre 2. Les couches adhésives 5 présentent des dimensions identiques à celles des couches adhésives 6. Dans le mode de réalisation décrit, les couches adhésives 5 et 6 consistent en des bandes adhésives double face. Comme représenté sur les figures 3 A, 3B et 4, les bandes adhésives sont dimensionnées pour s'étendre sur toute la longueur des bords latéraux du cadre 2 ainsi que sur toute la longueur des méplats. En revanche, elles présentent une largeur inférieure à celle des bords latéraux et des méplats. Comme on le verra plus loin, cette différence dimensionnelle permettra d'assurer la mise sous tension de la toile (2). [0028] La dalle de paroi 1 selon l'invention est réalisée selon les étapes suivantes (figures 3 A à 3D). As shown in Figure 2, each flat part 4a to 4d is fixed by a first adhesive layer 6 on the fabric 2 and a second adhesive layer 5 on one of the side edges 20a, 20d of the frame 2. The adhesive layers 5 have the same dimensions as the adhesive layers 6. In the embodiment described, the adhesive layers 5 and 6 consist of double-sided adhesive tapes. As shown in FIGS. 3A, 3B and 4, the adhesive strips are sized to extend over the entire length of the lateral edges of the frame 2 as well as over the entire length of the flats. However, they have a width less than that of the side edges and flats. As will be seen below, this dimensional difference will ensure the power of the canvas (2). The wall panel 1 according to the invention is made according to the following steps (FIGS. 3A to 3D).
[0029] La première étape consiste à revêtir le bord latéral extérieur 20a à 20d de chaque profilé 2a à 2d formant le cadre 2 ainsi que l'une des surfaces de chaque méplat 4a à 4d d'une bande adhésive 5, 6 double face. [0030] Comme représenté sur les figures 3 A et 4, les bandes adhésives 5 sont collées sur les bords latéraux du cadre 2 en étant positionnées en bordure des arêtes de la forme en équerre des profilés, préservant ainsi une zone longitudinale non adhésive 7 (ou zone longitudinalement dépourvue d'adhésif 7). De même, et comme représenté sur la figure 3B, les bandes adhésives 6 sont collées sur l'une des faces de chacun des méplats en étant positionnées en bordure de l'un des bords longitudinaux des méplats, préservant ainsi une zone longitudinale non adhésive 8 (ou zone longitudinale dépourvue d'adhésif 8). The first step is to coat the outer side edge 20a to 20d of each profile 2a to 2d forming the frame 2 and one of the surfaces of each flat 4a to 4d of a double-sided adhesive tape 5, 6. As shown in FIGS. 3A and 4, the adhesive strips 5 are glued to the lateral edges of the frame 2 while being positioned at the edges of the edges of the angled shape of the profiles, thus preserving a non-adhesive longitudinal zone 7 ( or area longitudinally devoid of adhesive 7). Similarly, and as shown in FIG. 3B, the adhesive strips 6 are bonded to one of the faces of each of the flats while being positioned on the edge of one of the longitudinal edges of the flats, thus preserving a non-adhesive longitudinal zone. (or longitudinal zone without adhesive 8).
[0031] Une fois les couches d'adhésif 5, 6 appliquées sur les bords latéraux 20a à 20d du cadre 2 et les méplats 4a à 4b, on positionne le cadre 2 sur la face arrière 31 de la toile 3, la zone non adhésive 7 du cadre 2 étant disposée du côté de la toile 2 (figure 3A). [0032] Vient ensuite l'étape de pose des méplats de renfort 4a à 4d sur la toile 3. Pour ce faire, chaque méplat de renfort 4a à 4d est placé sur la toile 3 en positionnant d'un part le bord longitudinal situé du côté de la zone non adhérente 8 de chaque méplat de manière jointive avec le bord latéral du profilé correspondant et d'autre part la face de chaque méplat 4a à 4d portant une bande adhésive double 6 côté toile 3 comme illustré sur la figure 3B. Préalablement au positionnement des méplats sur la toile 3, il aura été pris soin d'enlever la protection recouvrant l'adhésif de la bande adhésive double face. Ainsi, le bord longitudinal de chaque méplat bordant la zone longitudinale non adhérente du méplat est en contact avec la zone longitudinale non adhérente du bord latéral associé du cadre 2. [0033] Une fois les quatre méplats de renfort 4a à 4d fixés sur la toile 2, cette dernière est ensuite découpée le long d'une ligne de découpe 9 délimitée par chacun des méplats 4a à 4d et le cadre 2 afin de retirer la partie excédentaire de la toile, ie. la partie de la toile 3 s'étendant au-delà du cadre 2 et non renforcée par un méplat, et ainsi de former des volets (ou portions) de toile renforcés 3a à 3d. Once the adhesive layers 5, 6 applied on the side edges 20a to 20d of the frame 2 and the flats 4a to 4b, the frame 2 is positioned on the rear face 31 of the fabric 3, the non-adhesive area 7 of the frame 2 being disposed on the side of the fabric 2 (Figure 3A). Next is the step of laying the reinforcing flats 4a to 4d on the fabric 3. To this end, each reinforcing fl oor 4a to 4d is placed on the fabric 3 by positioning on the one hand the longitudinal edge of the fl oor. the side of the non-adherent zone 8 of each flat surface contiguously with the lateral edge of the corresponding profile and secondly the face of each flat portion 4a to 4d carrying a double adhesive tape 6 side cloth 3 as shown in Figure 3B. Prior to the positioning of the flats on the fabric 3, care was taken to remove the protection covering the adhesive of the double-sided adhesive tape. Thus, the longitudinal edge of each flat part bordering the non-adherent longitudinal region of the flat surface is in contact with the longitudinal non-adherent zone of the associated lateral edge of the frame 2. Once the four flats of reinforcement 4a to 4d fixed on the fabric 2, the latter is then cut along a cutting line 9 delimited by each of the flats 4a to 4d and the frame 2 to remove the part excess of the canvas, ie. the portion of the fabric 3 extending beyond the frame 2 and not reinforced by a flat, and thus form reinforced shutters (or portions) of fabric 3a to 3d.
[0034] Chacune volet de toile renforcé 3a à 3d est ensuite replié sur le bord latéral 20a à 20d associé du cadre 2, la feuille de protection de la bande adhésive double face ayant été au préalable retirée. Lors de cette opération, chaque méplat de renfort 4a à 4d va basculer autour de la ligne de jonction XX entre le bord longitudinal du méplat et la zone longitudinale non adhérente du bord latéral associé du cadre, entraînant ainsi la mise sous tension de la toile 3 sur le cadre 2. Il est entendu que l'opération de fixation des méplats de renfort lors du rabattement des volets de toile renforcés ne se limite par à la technique du collage, tout autre moyen et technique appropriés connus de l'homme du métier pouvant être mis en œuvre sans sortir du cadre de l'invention. En particulier, il peut être prévu une fixation des méplats de renfort sur le cadre par vissage, clouage ou spittage. Each reinforced fabric shutter 3a to 3d is then folded over the side edge 20a to 20d associated with the frame 2, the protective sheet of the double-sided adhesive tape having been previously removed. During this operation, each reinforcing flat 4a to 4d will swing around the junction line XX between the longitudinal edge of the flat and the longitudinal non-adherent zone of the associated lateral edge of the frame, thus causing the tensioning of the fabric 3 on the frame 2. It is understood that the fixing operation of the reinforcing flats when folding reinforced fabric flaps is not limited to the bonding technique, any other appropriate means and technique known to those skilled in the art can be implemented without departing from the scope of the invention. In particular, it can be provided a fixation of the reinforcing flats on the frame by screwing, nailing or spitting.
[0035] Afin d'assurer une planéité satisfaisante de la surface de la toile 3 recouvrant le cadre 2, le deuxième volet renforcé a être fixé sur le cadre 2 sera le volet de toile opposé au premier volet de toile renforcé fixé. Ainsi, si le premier volet renforcé est le volet 3b comme illustré sur la figure 3D, le deuxième volet à être fixé sur le cadre 2 sera le volet associé au profilé 2a (non représenté), le troisième volet étant l'un des deux volets restant (volets 3c ou le volet correspondant au profilé 2d). To ensure a satisfactory flatness of the surface of the fabric 3 covering the frame 2, the second reinforced flap to be fixed on the frame 2 will be the canvas flap opposite to the first fixed reinforced fabric shutter. Thus, if the first reinforced flap is the flap 3b as illustrated in FIG. 3D, the second flap to be fixed on the frame 2 will be the flap associated with the section 2a (not shown), the third flap being one of the two flaps. remaining (flaps 3c or the flap corresponding to the section 2d).
[0036] Une fois les quatre volets renforcés 3a à 3d fixés sur les bords latéraux 20a à 20d du cadre, la toile 3 étant alors tendue sur le cadre 2, il est procédé au chauffage de cette dernière afin d'enlever toutes déformations éventuelles produites au cours de la réalisation de la dalle de paroi et susceptibles de générer des marques visibles à l'œil nu sur la dalle de paroi. Le chauffage est réalisé par la face arrière 31 ou la face avant 30 de la toile 3 selon que la face réfléchissante de la toile est recouverte d'un film de protection (chauffage étant alors effectué par l'arrière) ou non (chauffage pouvant être effectué alors par l'avant de la toile). Il est à noter que dans le cas où la toile comporte un film de protection recouvrant sa face réfléchissant, il convient de retirer ce dernier une fois l'étape de chauffage achevée. [0037] Dans l'exemple illustré, lequel est un mode de réalisation préféré, les couches adhésives se présentent sous la forme de bandes adhésives double face. Il est bien entendu évident que la couche adhésive pourra prendre une autre forme que celle d'une bande adhésive double face, comme par exemple une couche adhésive directement active, ie. sans couche de protection. Dans ce cas là, on comprendra que l'application de la couche adhésive devra se faire à des moments bien précis lors de la réalisation de la dalle de paroi. En particulier, l'application de la couche adhésive sur chaque méplat sera appliquée avant leur pose respective sur la toile tandis que celle appliquée sur les bords latéraux du cadre sera réalisée après la pose du cadre de la face arrière de la toile, précédent ou suivant l'étape de pose des méplats sur la toile. Par ailleurs, dans le mode de réalisation décrit, l'adhésif est appliqué sous la forme de bandes. Il peut être cependant également appliqué sous la forme de bandes discontinues. Once the four reinforced shutters 3a to 3d fixed on the side edges 20a to 20d of the frame, the fabric 3 is then stretched on the frame 2, it is heated to the latter to remove any possible deformations produced during the realization of the wall slab and likely to generate marks visible to the naked eye on the wall slab. The heating is performed by the rear face 31 or the front face 30 of the fabric 3 according to whether the reflective face of the fabric is covered with a protective film (heating being then performed from the rear) or not (heating may be done then by the front of the canvas). It should be noted that in the case where the fabric comprises a protective film covering its reflective face, it should be removed after the heating step completed. In the illustrated example, which is a preferred embodiment, the adhesive layers are in the form of double-sided adhesive tapes. It is, of course, obvious that the adhesive layer may take another form than that of a double-sided adhesive tape, such as, for example, a directly active adhesive layer, ie. without protective layer. In this case, it will be understood that the application of the adhesive layer should be done at specific times during the production of the wall slab. In particular, the application of the adhesive layer on each flat will be applied before their respective laying on the canvas while that applied to the lateral edges of the frame will be performed after the installation of the frame of the rear face of the fabric, previous or next the step of laying flats on the canvas. Moreover, in the embodiment described, the adhesive is applied in the form of strips. However, it can also be applied in the form of discontinuous strips.
[0038] Dans le mode de réalisation précédemment décrit, la toile est fixée sur le cadre par collage, et plus particulièrement par collage des méplats sur la toile et sur les bords latéraux du cadre. Il est entendu que l'invention ne se limite pas à ce type de moyen de fixation, ladite toile pouvant être fixée par tout autre moyen et technique appropriés connus de l'homme du métier sans sortir du cadre de l'invention, comme par exemple par rivetage des éléments entre eux (toile, méplat et cadre), par clipsage, etc.. In the embodiment described above, the fabric is fixed to the frame by gluing, and more particularly by gluing flats on the fabric and on the side edges of the frame. It is understood that the invention is not limited to this type of fastening means, said canvas can be fixed by any other appropriate means and technique known to those skilled in the art without departing from the scope of the invention, such as for example by riveting the elements between them (canvas, flat and frame), by clipping, etc.
[0039] De même, dans l'exemple décrit précédemment, le cadre est formé de quatre profilés distincts. Il est bien entendu possible que le cadre soit constitué d'un seul élément profilé, ledit cadre étant réalisé par pliage et découpage dudit élément profilé. Similarly, in the example described above, the frame is formed of four separate profiles. It is of course possible that the frame consists of a single profiled element, said frame being made by folding and cutting said profiled element.
[0040] De même, dans l'exemple décrit précédemment, le cadre 2 est de forme sensiblement parallélépipédique. Il est entendu que l'invention ne se limite pas à une telle forme de cadre, la dalle pouvant comprendre un cadre présentant une forme différente, comme par exemple une forme triangulaire (dans ce cas, la dalle de paroi comprendra trois méplats de renfort placés chacun entre un des bords latéraux du cadre et une portion de toile recouvrant le bord latéral en question) ou circulaire (dans ce cas, la dalle de paroi comprendra un ou plusieurs méplats de renfort s 'étendant entre le pourtour du cadre et la portion de toile recouvrant le pourtour en question). [0041] De même, dans l'exemple décrit précédemment, les volets de toile renforcés sont fixés plaqués contre les bords latéraux du cadre. Selon une variante de réalisation, il est prévu de rabattre partiellement les volets de toile sur les bords latéraux du cadre, les volets renforcés présentant ainsi une position inclinée par rapport aux bords latéraux dudit cadre. Cette configuration a pour avantage d'offrir une mise sous tension de la toile plus importante sur le cadre permettant encore une meilleure tension. Similarly, in the example described above, the frame 2 is of substantially parallelepipedal shape. It is understood that the invention is not limited to such a frame shape, the slab may comprise a frame having a different shape, such as a triangular shape (in this case, the wall slab will include three reinforcement flats placed each between one of the side edges of the frame and a portion of fabric covering the lateral edge in question) or circular (in this case, the wall tile will comprise one or more reinforcing flats extending between the periphery of the frame and the portion of canvas covering the perimeter in question). Similarly, in the example described above, the reinforced canvas shutters are fixed against the side edges of the frame. According to an alternative embodiment, it is intended to partially fold the fabric flaps on the side edges of the frame, the reinforced flaps thus having a position inclined relative to the side edges of said frame. This configuration has the advantage of providing a tensioning of the larger fabric on the frame allowing even better tension.
[0042] L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention. The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
