FLOOR COVERING PLATE WITH TILED SURFACE AND MANUFACTURING METHOD THEREOF

The present invention relates to a modular plate comprising a tiled surface and intended for producing a tiled floor. It also relates to a process for the manufacture of said modular plates.

Both in the construction of new buildings and in the renovation of old buildings, it is becoming increasingly important today to combine an aesthetic aspect with an insulating character of the product applied. The isolated product must also have a certain ease of installation to avoid the need for specialized personnel who are generally expensive.

The laying of a tiling, especially in the case of the renovation of old buildings, generally involves difficulties as to the thicknesses and levels to be expected. Generally, it is necessary to provide a layer of thermal and possibly acoustic insulation, a concrete screed and a thickness of mortar in which 2 g would fit the tiles. These arrangements generally lead to thicknesses of 10 to 15 cm.

In addition, conventional tiling can only be applied with difficulty to a wooden floor. As a result, the comfort and ease of tiling are only rarely possible in a house with a wooden structure or in a construction comprising a wooden storey or mezzanine, for example.

The present invention therefore aims to provide a modular type ^ floor covering plate having a tiled surface and which allows the realization of a tiled covering applicable on a concrete floor as well as on a wooden floor, maintaining a thickness scaled down.

Another object of the present invention is to provide a floor covering plate which can be applied equally well to new buildings, whether in prefabricated construction or to so-called traditional construction, than to buildings undergoing renovation. The product must ► 2 s', r- 4 be easy to use, must ensure, as soon as it is installed, insulating and waterproofing properties; the plate used must not deform either in use or in storage and must be able to correspond, as regards its appearance, to conventional coatings.

An additional aim of the present invention consists in providing a modular plate allowing the production of a floor comprising thermal and acoustic insulation.

The objects of the present invention are achieved by a modular type floor covering plate having a tiled surface characterized in that it has a back made of an essentially rigid material, coated with a foamed synthetic material in which 15 are partially embedded tiles sticking to it.

Preferably, the foamed synthetic material consists of a polyurethane foam, more particularly a closed cell polyurethane foam. According to an advantageous embodiment of the present invention, the back can consist of a relatively rigid sheet of cardboard or of an asbestos plate. Other materials may also be suitable, such as veils of textile material or glass fibers. The tiles may of course be chosen in any manner and consist of conventional tiles, in particular ceramic tiles, which have not undergone any particular preparation treatment. It is essential, in order to ensure sufficient resistance of a tile produced according to the present invention, that the foamed synthetic material has a density such that the plate meets the usual standards of resistance to compression and sinking. According to the present invention, it has been found to be particularly advantageous to use a polyurethane foam having a density of 40 to 50 g / m3.

It is surprising to note that a modular element according to the present invention allows the laying of a <% ï f 3 tiling both on a concrete floor than on a wooden floor while ensuring a largely sufficient resistance to compression, to sinking and wear. Furthermore, a tiling produced using the modular elements according to the invention ensures good thermal and acoustic insulation, in particular thanks to the use of a foamed synthetic material.

A modular plate according to the present invention can be easily installed by gluing or screwing or by simple deposition on the support. It can also include recesses and lateral projecting parts allowing interlocking. It is easily adaptable to the contours of the support to be covered since the synthetic material is easy to cut and use. It is obvious that after laying, the flooring must be repointed; this operation can be carried out in a completely conventional manner, using a usual repointing cement. It should also be noted that the laying of a tiling using the modular plates 20 according to the present invention is very rapid. This can be particularly important in the case of the renovation of a building, where the inhabitants can occupy the freshly tiled room, immediately after the installation of the modular elements, without having to wait for a drying time of several days, as in the case of classic tiles.

According to the invention, plates of the aforementioned type are obtained by depositing on the bottom of a mold, with the outside face facing down, tiling plates 30 t, with a space corresponding to an ordinary joint, in that partially filling said joint with dry sand made up of a mixture of fine sand and coarse sand, so as to obtain a particle size range of 0-6 mm, provided that a back adheres to the product finished after which the mold is closed leaving a space at least equal to the thickness of the wafer and a plastic material capable of foaming is injected into the mold, preferably a foamable polyurethane. .

\ \ 4

It is observed that, the foam not only fills the empty space of the joint between the plates but also that it agglomerates and stabilizes a thickness of the order of a few millimeters of sand in the joint, thus forming, after demolding, in the joint, a bonding layer formed by a layer of hardened sand agglomerated by the foam. This layer has remarkable bonding properties for a repointing finish with a conventional mortar, this of course after the excess sand 1 q, which is easily removed after demolding has been removed. It is also found that the seal thus formed, even before repointing, is sufficiently tight to prevent the passage of moisture. Finally, the plate obtained is stiffened by the gasket lining and it does not deform during storage and during application, both for renovation use and for finishing a new construction.

The tiles used are chosen in any way. The shape of the mold and therefore of the modular plate according to the invention may have a shape adapted to the dimensions and shapes of the chosen tiles.

The invention is described in more detail below with reference to the attached single figure.

2 5 In a mold comprising a bottom 1, lateral edges 2 and a cover 3, there are tiles at the bottom of the mold 5. These plates 5 are spaced apart, leaving between them the width of a joint 6. This joint is partially filled with sand, for example jus-3Q only about half the height of the pads.

Before closing the lid on the mold, interpose a sheet of cardboard or an asbestos plate.

A foamable preparation is then injected into the mold and its expansion is then allowed.

The foamable preparation fills the free spaces (that is to say not occupied by the sand) between the plates and all the remaining space of the mold. The expanded foam is shown schematically at 8.

4 D

Part of the foam agglomerates on a reduced thickness, the sand placed between the joints.

After stabilization of the foam, the panel is removed from the mold, and the excess sand is recovered. At the joints 5 between the tiles, the sand, under the action of foam, has formed a very hard, rough and tight layer, placed approximately half the height of the joint between the tiles, the remaining half of the joint on the rear face is filled with foam which causes cohesion of the plates in connection with the hard seal placed halfway up in the seal.

On the front face, after removal of the sand, there remains about half a height of plates about a spacing which will make it possible to possibly receive screws for fixing the plate on its support and which will be subsequently repointed.

Although a preferred embodiment of the invention has been described, it should be understood that the invention is not limited thereto and that numerous modifications and variants remain possible within the scope of 1 'invention.
