ABSTRACT:
A double floor contruction is proposed which has supports set up at predetermined intervals on a stable substructure and tile-like floor elements bedded directly or indirectly on said supports. Each tile-like floor element is formed by a composite construction of a plurality of superposed layers of different materials, whereby the composite contruction is composed of a cover tile made of ceramic material, a core layer made of rigid material with low volume weight and a thin bottom layer with high tensile strength properties. This double floor construction solves the problem of allowing for the individual tile-like floor elements to be optimally selected in terms of their dimensions, in particular their thickness, while nevertheless being capable of taking up high loads. It also allows for the surface to be resistant to organic solvents and other chemicals. Finally, the floor coverings do not require for their bond with the subfloor any adhesive that might be critical in terms of its stability.
