Definitions
- the invention relates to the field of wall tiles intended in particular to form a suspended ceiling or a wall wall.
- 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.
- 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.
- PVC polyvinyl chloride
- the canvas 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.
- 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.
- the image reflected on the canvas presents distortions.
- 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.
- the invention aims to remedy these problems by proposing a mirror wall slab having an optimal tension of the fabric on the frame.
- 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.
- 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.
- rear face the face of the non-visible fabric of the inside the room in which the wall slab is installed.
- flat a part having a profile of rectangular section and thin.
- the reinforcing flat has a thickness greater than 0.5 millimeters.
- 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.
- 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.
- the reflective outer face is coated with a protective film, preferably peelable.
- 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.
- 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.
- the fabric is cut along a cutting line defined by the reinforcing flat and the frame.
- the method comprises a step of heating the fabric once the latter stretched on the frame.
- FIG. 1 shows a schematic sectional view of a wall panel according to the invention
- FIG. 2 represents an enlarged detail view of the wall slab of FIG. 1;
- FIGS. 3A to 3D show a schematic illustration of the steps for producing the wall slab of FIG. 1;
- FIG. 4 shows a sectional view of the frame of the wall plate of Figure 3 A.
- a wall panel 1 comprising a frame 2 of substantially parallelepiped shape and a web 3 mounted on said frame.
- 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.
- 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.
- the fabric 3 is fixed on the frame 2 by means of reinforcing flats 4a to 4d.
- 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.
- 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.
- 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.
- 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.
- the adhesive layers 5 and 6 consist of double-sided adhesive tapes.
- 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).
- 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.
- 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).
- 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).
- 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.
- 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.
- 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.
- 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.
- the second reinforced flap to be fixed on the frame 2 will be the canvas flap opposite to the first fixed reinforced fabric shutter.
- 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).
- 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).
- the fabric comprises a protective film covering its reflective face, it should be removed after the heating step completed.
- the adhesive layers are in the form of double-sided adhesive tapes.
- 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.
- the application of the adhesive layer should be done at specific times during the production of the wall slab.
- 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.
- the adhesive is applied in the form of strips. However, it can also be applied in the form of discontinuous strips.
- 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.
- 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.
- the frame 2 is of substantially parallelepipedal 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).
- the reinforced canvas shutters are fixed against the side edges of the frame.
