Description

The present invention relates to a framing rod for the use of laminate sheets for the constitution of internal walls of dwellings, decorations, furnishing elements and the like of flat or curved shape, said rod being intended to border on its sides a laminate sheet of polygonal shape.

Such a strip made of wood is known from document FR-A-1 475 446 for making false ceilings, this strip having a groove in which is engaged an edge of elastic plastic material, integral with a sheet stretched in a frame formed by such rods.

Document FR-A-2 095 463 reveals an element of false ceiling and various coverings, formed of a rigid frame coated with a veil.

Document FR-A-2 355 674 relates to a device allowing the installation of wall hangings and frames, comprising an angle iron of aluminum or a similar material which is perforated so as to be malleable.

In document FR-A-2,525,961, a process has previously been described which makes it possible to use laminate sheets to constitute internal walls of dwellings, decorations or attics. In particular, a method has been described in which each laminate sheet is surrounded by a strip with a gripper profile, the sheet being able to take a curved shape by bringing the strips together with two parallel edges.

The present invention relates more particularly to a construction method of this kind and, more particularly still, to a particular profile of framing strip for laminate sheet, by means of which the framing can be carried out on the edges of 'a sheet of polygonal shape.

The framing strip according to the invention for the use of laminate sheets for the constitution of internal walls of dwellings, decorations, furnishing elements and the like, said strip being intended to border on its sides a laminate sheet of polygonal shape is formed from a profile consisting of a solid central core forming the core of the profile. Two superimposed wings extend from one side of said core outwards, the upper wing comprising a recess so that the two superimposed wings delimit between them a stepped groove to allow the reception of laminates of different thicknesses, one edge of which engages inside said groove, said upper wing having its curved edge to delimit a first upper groove. A third wing extends on the other side of the core upwards and carries a rib extending parallel to the first two wings and forming with the upper part of the core a second upper groove symmetrical with said first groove and defining with the latter a slide to receive connecting pieces of the adjoining rods. Said third wing also has, above said rib, a curved edge opposite to said rib to ensure the positioning of the rod on a primary support structure preferably formed of inverted T profiles. Said strip profile is made in one piece, in a material such that can be bent to achieve, by framing the laminate sheets, walls and the like of curved shape.

Once the panel is framed on its edges by profiles integral with each other, the slab thus formed, curved or flat, is maintained in the desired shape, which allows the transport in the form of the slabs, without fear of deformation, a placement without having to perform any effort on the panel, and disassembly of each slab separately and individually without prejudice to neighboring slabs.

By means of such profiles, it is thus possible to stiffen a sheet of laminate and produce self-supporting tiles with a flexible material;

• assurer par un même profilé le montage de stratifiés d'épaisseurs différentes (par exemple 13/ 10 mm, 4 mm et 16 mm); les épaisseurs de 4 mm et 16 mm ou même 19 mm sont utilisées dans le cas de dalles planes permettant en particulier l'encastrement d'appareillage type spots encastrés, détection incendie et analogues;
• permettre les variations dimensionnelles du stratifié en fonction de l'humidité, ce qui évite de prévoir des joints de dilatation intermédiaires.

make, by suitably curved profiles, curved slabs;

• ensure by the same profile the mounting of laminates of different thicknesses (for example 13/10 mm, 4 mm and 16 mm); the thicknesses of 4 mm and 16 mm or even 19 mm are used in the case of flat slabs allowing in particular the installation of equipment such as recessed spotlights, fire detection and the like;
• allow the dimensional variations of the laminate as a function of humidity, which avoids having to provide intermediate expansion joints.

By means of the upper groove, it is possible not only to assemble the frame by means of invisible brackets after assembly, but also by sliding pieces to fix the tiles to hangers formed for example of threaded rods.

Advantageously, the profile is produced by drawing in aluminum, but it can also be obtained in any other extruded, injected or molded material.

Bending is preferably carried out hot, the shape chosen with a solid central core allowing bending without deformation of the visible face of the profiles.

An embodiment of a profile according to the invention will now be described by way of example, as well as its implementation for the construction of panels of different shapes, with the aid of the appended drawings in which:

• Figures 1a and 1b are sections of the profile with laminate sheets of different thicknesses;
• Figure 2 is a section showing two adjacent panels supported by the same T-shaped frame member;
• Figure 3 is a section showing other modes of support;
• Figure 4 is an exploded view showing a junction by a corner piece;
• Figure 5 is a sectional view of a convex rod;
• Figure 6 is a sectional view of a concave rod.

The profile for the framing of a laminate panel according to the invention is shown in section in Figures 1a and 1b. It consists of a central core or core 1 from which extend, on one side, a lower wing 2 and an upper wing 3, this wing 3 having a recess 4 so as to form a groove 5 capable of receiving, either a thin panel (Figure 1a), or a thicker panel (Figure 1b), without appreciable play other than that necessary for the expansion or for the bending of the panel. The upper wing is curved at 6 parallel to itself to form an upper groove 7, which advantageously cooperates with a symmetrical groove 8 formed between a rib 9 parallel to the first two and the upper wing 3, these two grooves 7 and 8 can be used as a slide for an annex piece, assembly or support as will be described later.

On the other side of the core 1, and at its upper end situated above the rib 9, extends a wing 10 intended to rest on a support parallel to the profile, and itself constituted for example by a inverted T-profile 11 (FIG. 2), which thus receives for example the parallel rods of two adjacent panels 12 and 13, a clip 14 can also be used.

As can be seen from FIG. 3, other forms of support can be provided, for example with a re-entrant angle, such as the profile 15 or projecting angle, profile 15 ′, which allows the appearance provided by a false ceiling.

Also shown in this same figure is a panel 16 in wall presentation held vertically along a partition 17.

As has been said, a framing strip is placed on each of the four edges of the panel, the strips can be bent identically on both sides so as to form a concave or convex panel, the other two strips being parallel and straight . At each angle thus formed, the two rods are assembled by a square piece 18 (FIG. 4), the branches of which are introduced into the upper grooves 7 and 8 forming slides and are held in place for example by screws 19 driving into the partition 3. If the two strips are cut at 45 ° angles, the adjustment is carried out in a conventional manner.

When the panels are curved concave (FIG. 6) or convexly (FIG. 5), it is advisable to leave a straight portion 20 at the two ends of each strip to allow the angle pieces 18 to be adjusted.

As has been said, the advantage of such framing is to constitute, before installation, the constitution of panels having the desired shape and dimensions, panels of which the stress forces are taken up by the framing so that they do not exert no effort on their supports and that these only have to support the weight, which can be very low.

Although in the embodiments described, quadrangular panels have been used, panels with a different number of sides could also be used, for example triangular panels.
