DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for fixing a decorative board to a wall.

In particular, the invention finds application in fixing marble slabs useful for the decoration of structures.

In main structures, decorative marble slabs are often placed on the structural walls.

These marble slabs must be fixed independently of each other, and the current method of embedding them in walls is a time-consuming and difficult process, and also presents various problems regarding the alignment and flatness of the marble slabs. occurs.

The present invention seeks to solve these problems by automatically arranging and flattening the decorative plates, thereby making their installation simple and rapid.

For this purpose, the fixing device according to the invention comprises: - a profile to be arranged parallel to the middle of the decorative board;
Each profile has a rear flange that rests against the wall, a front flange that together with this rear flange delimits the storage area of the decorative panel edge, and a connecting web between these rear and front flanges. the web includes a profile provided with engaging bodies forming two fitting spaces open on opposite sides; - a fixing member for fixing the profile against the wall by means of a rear flange; - elastic means arranged on the rear flange for crimping and holding the decorative plate against the front flange; - tenons arranged in the engaging bodies of the profile; and tenons arranged in the engaging bodies of the profile; and a profile retaining part with retaining means for securing therein.

The profiles can in particular be made of light aluminum alloy, and in each case by appropriate anodization they can be adapted to the appearance of the decorative board, in order to give the entire structure a good decorative effect.

The device of the present invention allows decorative plates to be placed very quickly.

That is, the sections are fixed perpendicularly to the wall using a "spigot" type fixing device driven in by an automatic driving pistol, and then each decorative board is placed between adjacent sections parallel to each other, and the decorative board is placed between adjacent sections parallel to each other. Each time a board is placed, a fixing component is installed to fix the decorative board.

In this case, these decorative plates are supported by holding parts,
Note that there is no load transfer between the upper and lower decorative plates.

The elastic means for holding each decorative plate against the front flange of the profile consist, in particular, of a spring plate fixed on the rear flange of the profile.

This spring plate is preferably fixed on the rear flange of the profile by the same fastening means (in particular bolts or nails installed by pyrotechnics) when the profile itself is fixed on the wall. .

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

The apparatus illustrated in FIGS. 1, 2 and 3 includes a profile 1
Including aluminum light alloy extrusion shapes such as.

Each profile 1 arranged perpendicularly to the wall to be coated (indicated by M in FIG. 3) comprises a rear flange 2 abutting the wall, a front flange 3 and a web 4; The web is provided with an engaging body 19 forming two fitting spaces 5 and 6 open on both sides.

The rear flange 2 and the front flange 3 form a storage area for the edge of the decorative plate P disposed between them, and are therefore spaced apart from each other by a distance greater than the thickness of the decorative plate P. The front flange 3 is provided with short inward folds 7 and 8 on both sides thereof (indicated by dashed lines in the figure and solid lines in Figures 2 and 3), and these folds serve as supports for the decorative plate P. It serves as a body.

The rear flange 2 has two side parts 2a and 2b extending beyond the front flange 3 on both sides, each part 2a or 2b having two inwardly directed ribs 8 and 10, respectively 1, and between these ribs a respective decorative plate. The spring plate 11 is fixed at the level P.

These spring plates have a convex cross-section projecting against each rib 9 and 10 and are crimped onto the decorative plate P so that this plate can be attached to the folds 7 or 8 of the front flange 3 as shown in FIG. Crimp.

The leaf spring 11 is fixed in the profile by a striking means 12.

This striking means 12 is installed by pyrotechnics through the rear flange 2 and also serves to hold the profile against the wall.

Ribs 9 and 10 prevent the heads of these striking means from protruding.

This is to prevent the risk of damage to the marble by not posing an obstacle when installing the decorative plate P, and to eliminate the possibility of causing a fracture initiation part of the marble.

Furthermore, each of the fitting spaces 5 and 6 forms an inverted dovetail shape as shown.

The engaging body 19 forming the fitting spaces 5 and 6 slides the tenon 13a of the holding component 13 inside thereof, thereby disposing the holding component 13 at a desired height.

Therefore, the tenon 13a has a shape corresponding to the fitting space 5 or 6, and a fixing means consisting of a set screw 14 with a square hole is screwed into the screw hole of the holding part 13 and passes through the tenon 13a, It is crimped onto the side wall of the connecting web which delimits the fitting space 5 or 6.

This set screw 14 is slightly inclined and protrudes above the upper surface of the holding part 13 to facilitate adjustment.

In the embodiments of FIGS. 1, 2 and 3, each retaining portion 13 has an inclined lower surface of the reservoir that abuts the beveled section made at the edge of the decorative plate and a lower end of the adjacent upper decorative plate. and the horizontal upper surface of the dam supporting the dam.

As can be understood from FIG. 2, the inclined lower surface of each holding part 13 is for fixing the decorative plate underneath, and the soil surface of the holding part 13 supports the upper decorative plate. Although the upper and lower plates are in contact with each other, they are independent from each other without transmitting any load between them.

The device described above places marble slabs, granite slabs, or similar material slabs very rapidly against a wall.

At the same time, the alignment and perfect flatness of these plates can be guaranteed.

First, a large number of sections 1 are fixed perpendicularly to a wall and spaced apart from each other at a distance slightly larger than the width of the decorative board to be installed.

As mentioned above, this fixing is carried out by nailing at different height levels of the profile, and at the same time a spring plate 11 can be installed at the level of each decorative board.

Next, in order to fix the decorative board, two holding parts 13 are placed in the two opposing sections that support the decorative board, and these holding parts are placed at an appropriate height (already fixed). The edge of the top plate to be fixed is then fitted into the recess defined by the profile flange and moved downwards along the profile. All you have to do is slide it.

When this decorative board is placed on the two holding parts below it, two other holding parts are installed to fix the upper part of this decorative board.

It will be appreciated that such an installation method is extremely simple and can be implemented quickly.

In some cases, the removal of the decorative plate can also be carried out very quickly by reverse operation.

In the illustrated embodiment, the front flange 3 of the profile extends laterally beyond the holding part 13 in order to cover the gap at the level of the oblique section of the decorative panel.

In this way, a facade structure is obtained in which the marble decoration is interrupted by vertical narrow aluminum surfaces, which gives it a very good aesthetic appearance.

4 and 5 show another embodiment of the device of the invention.

In this case, the profile has a slightly different connecting web, in which the front flange 3 is divided into two parts 14 and 15 separated from each other by a concave surface 16.

Of course, other shapes are also conceivable depending on the desired decorative effect.

Also in this embodiment, each holding part 17 has a parallelepiped end, which end is arranged inside a correspondingly shaped cutout made in the edge of each decorative plate.

In this way, the upper plate and the lower plate are fitted into and fixed to the end portion of the holding component.

These decorative plates are then placed in mutually joined positions without mutually transmitting loads.

In this embodiment, the set screw 18 is arranged horizontally on the top of the holding part so that it can be adjusted when the holding part end is inserted into the cutout in the lower plate.

The present invention is not limited to the above description, but can be modified and implemented as desired within the scope of the spirit thereof.
