Abstract

The tile 1, particularly for use as a floor tile, has an upper layer 2 formed with sintered finely ground materials, preferably spray-dried clay, and a lower layer 3 formed from a plastic material, preferably recycled plastic material. The tile may also include an intermediate layer 4 formed from refractory material, preferably foundry scraps, and may include a set of projections 5 extending down from the lower layer to aid floor laying.

Description

Mu ! ti-laycrtype tile

The present invention refers to a multi-layer type tile.

It is known that the currently produced floor tiles are made up of sintcred materials and in particular are made in one or more layers, still with spraydried clay of top quality and extremely fine grinding.

These tiles have a relatively low sound-absorption coefficient and thus do not constitute a barrier to the passage of sound waves. Further on. the laying requires an even floor and the weight of the individual piece is high.

Purpose of this invention is to produce a multi-layer type tile free of the above inconveniences.

Further purposes of this invention shall be described into details in the following description.

Subject of this invention is a multi-layer type tile, as described in the preamble of appended claim I, and characterized by what disclosed in the characterizing portion of the same claim 1.

This invention shall be further on described with reference to the enclosed drawings, that show a non-limiting application, where : - figure 1 is a perspective view of a tile produced according to this invention ; - figure 2 is a section, on enlarged scale, of the tilc in figure 1.

With reference to the figures 1 and 2. number 1 corresponds to the whole tile-multi-layer type. including an upper layer 2 with sintcred materials and in particular with spray-dried clay, of top quality and extremely fine grinding, a lower layer 3 in plastic material, preferably in recycled plastic material and an intermediate layer 4 made up of refractory material such as for example foundry scraps. The lower layer 3 has a set of projections 5 for the floor laying.

From the above, the advantages achieved by the realization of this invention are clear.

In particular, the produced tile. with the same total thickness with respect to a currently marketed tile, is lighter ; in particular, tile 1 has an average weight of 14 kg every square meter of surface, against the average weight of 20 kg every square meter of currently marketed tiles. In addition, the tile 1, due to the type of material used to define the lower layer 3, has a relatively high sound-absorption coefficient. This feature is very appreciated by the market, to improve the house sound insulation. It is to

he pointed out that, to realize the layers 3 and 4, scrapped materials can be used, contributing to the reduction of the materials to be sent to the rubbish dump and thus decreasing costs for those companies producing those scrap materials. In addition, the presence of projections 5 enables a more precise laying of the tiles 1 on unlevelled floors and the possibility of a safer gluing of tiles 1 on the floor, through standard technical glues that cover the space defined among the different projections 5.
