• the invention relates to the technical field of false suspended ceilings and false walls.
• the invention relates more particularly to slabs of false ceilings or false walls comprising a stretched canvas and a frame.
• the fabric is made of polyvinyl chloride and is firstly tensioned before being fixed on a frame, this frame being itself previously obtained by assembling aluminum profiles.
• the aluminum profiled element comprises two wings, namely a vertical outer wing on which is fixed the polyvinyl chloride cloth, and a vertical inner wing whose base is set back from the base of the outer wing so as not to come into contact with the canvas.
• the aluminum profile element has two wings, namely a vertical outer wing on which is fixed the polyvinyl chloride cloth, and an inner inclined or vertical wing whose base is located below the base of the outer wing so as to come into contact with the canvas.
• the aluminum profile element comprises a horizontal upper wall, a vertical side wall and an oblique stiffening wall, the section forming a box.
• the T-shaped elements supporting the slabs should preferably be as discrete as possible, the width of their transverse branch should be as small as possible so that the false suspended ceiling has an appearance as close as possible to that of a real ceiling.
• the assemblies described in the documents FR 2 793 504, FR 2 793 506 or FR 2 789 101 do not make it possible to significantly reduce the width of the T-shaped support elements, in particular when the slabs are of large surface area, except that the bonding area of the canvas is apparent.
• the larger the slab the greater the bonding area of the fabric to the frame, this bonding area can no longer be masked by the T-shaped support, except to increase the width of this T-section.
• the slab described in document FR 2 793 506 has the additional disadvantage that the fabric of each slab is not stretched flat on its frame, the finish of the false ceiling can not be close to that of a conventional ceiling plane. Reference can also be made to WO 9950512.

• the Applicant has endeavored to solve this problem in a simple, fast, and inexpensive way, without changing the structure of the slab frame or the process for pocketing it.
• the invention relates, according to a first aspect, to a false ceiling slab frame, at least one side of this frame comprising, when seen in section, an upper wall and a side wall, the upper wall being provided with a flat surface, this flat comprising at least two through holes of assembly means such as screws, one of the through holes being oval or oblong.

• the frame comprises a second stiffening wall, this second wall forming a box with the first stiffening wall and the lateral wall; - said frame side comprises, when viewed in section, a substantially horizontal upper wall, said obtuse angle being between 1 degree and 60 degrees, and more particularly between 5 and 20 degrees.
• the invention relates, in a second aspect, to a false ceiling slab comprising a frame as presented above, and a canvas in which the frame is bagged, thereby defining a lower stretched canvas strip and a stretched canvas strip. higher.
• the invention relates, in a third aspect, to a false ceiling comprising a slab as presented above, this slab being mounted on an inverted T-shaped support.
• FIGS. 1 and 2 are sectional views of slabs comprising a frame, this frame being bagged in a fabric, a mounting bracket being in place in the variant of Figure 2;
• Figure 3 is a top view of the slabs shown in Figures 1 and 2.
• the slab frame 1 shown in Figure 1 is for example made of aluminum alloy, by extrusion.
• This frame 1 comprises a substantially horizontal upper wall 2, and a side wall comprising a substantially vertical upper portion 3 and a lower inclined portion 4.
• the upper part 3 and the lower part 4 define an angle ⁇ (alpha) of the order of 10 to 20 degrees, this angle alpha being obtuse when measured in the outer face of the frame.
• the lower part 4 goes away from the inside 5 of the frame 1.
• the frame further comprises an inner wing 6 substantially vertical and parallel to the upper part 3 of the side wall.
• On this inner flange 6 are formed two grooves 7, 8 with an inwardly facing opening 5 of the frame 1. These grooves 7, 8 serve, where appropriate, to mount a support angle 9 for an insert, such as that for example a sound insulation insert and / or thermal, or even a lighting device.
• the frame 1 also comprises a horizontal bearing surface 10 of small width, in the lower part of the side wall. In the embodiments shown, the lower part 4 of the side wall, the angle alpha and the width of the horizontal bearing surface 10 are chosen such that this bearing surface 10 extends substantially completely towards the outside of the frame relative to a vertical plane P corresponding to the upper part 3 of the side wall.
• This embodiment makes it possible to marry at best the shape of the supports 11 of inverted T bars 12.
• the frame 1 further comprises a first substantially horizontal stiffening wall 13.
• This first stiffening wall forms a box 14 with the upper wall 2, the upper part 3 of the side wall and the inner wing 6.
• a C-groove may be placed to house a joint splice or bracket 15 of two contiguous frame sections.
• three C-grooves extend in the box 14. These three grooves 21, 22, 23 extend on the upper wall 2, the upper part 3 of the side wall and the first wall of stiffening. Each of these grooves allows the establishment of splices or brackets assembly of contiguous frame sections.
• the frame 1 further comprises a second stiffening wall 16 connecting the bearing surface 10 and the inner wing 6.
• This second stiffening wall forms a box 17 with the side wall, the bearing surface 10 and the first wall stiffening 13.
• the frame is bagged in a fabric 18, so as to define a lower fabric band 19 and an upper fabric band 20.
• the fabric is advantageously heat-shrunk onto the frame.
• these two strips of fabric are substantially parallel. Between these two strips 19,20 sound and / or thermal inserts (not shown) can be mounted on brackets 9 or any other ad hoc support, mounted on the frame 1 by the grooves 7, 8.
• the presence of two grooves 7, 8 (or more) makes it possible to adjust the mounting height of the angles 9.
• the angle between the horizontal and the stiffening wall 16 is of the order of 40 degrees
• the angle between the horizontal and the lower part 4 of the side wall is 70 degrees

• Translucent or opaque, tinted or not in the mass, matt, lacquered, marbled, suede or satin, these materials can be used both in industrial and hospital environments, for public facilities, laboratories or homes.
• the lacquered finish allows a mirror effect often implemented in shopping centers, a matte finish close enough to a plaster aspect being more usual to traditional decorations.
• the slab frame thus designed has a high resistance to deformation, due to the presence of the obtuse angle ⁇ (alpha) and the presence of stiffening walls forming caissons.
