DOUBLE FLOORING »
This invention is directed to a double deck construction consisting of support brackets mounted on a sturdy construction underlying predetermined distances, and by plate-like floor elements seated directly or indirectly on these support brackets and which are formed by a association of several layers of different materials placed on top of each other.
It is common for a group of such widely used floor elements that they consist of a tub-like structure that is constructed in the form of a sheet metal or steel frame combined with a sheet bottom. The filling of this trough consists of different materials such as plaster, concrete, wood fiber materials or the like. A pan coating consisting of a filler particleboard core may also be used. Another group of such floor elements θ consists of tubular steel sections or pressure injection molded aluminum plates.
Both groups have as their top closure a hard carpet or polyvinyl chloride cover. Therefore all static requests that arise have

be received by the construction of the tub, as the top covers cannot make any contribution to this.
Recently, however, great demands have been placed on double-deck constructions, with load resistances up to 1,000 kg / 60 x 60 cm elements being required. But these demands lead to a considerable increase in the elements, which can lead to a dullness of the building and difficulties with the floor height dimensions. Moreover, such elements are then evidently considerably heavier, which have inconvenient action on the underlying sturdy construction.
It is the object of the present invention to provide a double-deck construction in which the individual plate-shaped floor elements can be optimally selected in relation to their dimensions in particular their thickness, but it is possible to receive higher loads. In addition, it is intended to obtain superior surface resistance against organic solvents and other chemical compounds and, finally, it is intended that floor coverings do not need to be bonded to the lower floor of any glue, which could make it doubtful. its stability.
According to the present invention this problem is solved if said combination is comprised of a cover plate made of ceramic material, a core layer made of a low weight bending-resistant material per square meter and a thin lower layer with good surface characteristics. resistance to traction. With such a construction considerable weight reduction can be achieved compared to known constructions, considerably higher static resistance, height savings

of floor construction for an equal interval or equal height for larger intervals. Moreover, there is no metal element which could possibly be subjected to corrosion.
Preferably, the different layers of said association are bonded together by the use of a glue, possibly under pressure.
It is particularly advantageous for the cover plate to consist of a high compressive strength plate obtained from an initial compressed, flattened and baked plastic ceramic starting material whose thickness is 1:45 000 of the upper area in the case of 30 x 30 cm dimensions of the plate.
As a core layer a porous material or a bee's nest material is advantageously used, in which case the comb axes are arranged perpendicularly to the cover plate. The core layer may also be of ceramic material, which can easily be treated to form a porous body or a bee nest body, the lower layer preferably consisting of a glass or mineral fiber fabric or bedding. charcoal or plastic. In the case of | The use of ceramic material for the core layer and / or layers of fiberglass, minerals or charcoal for the lower layer is conveniently effected by means of an enamel or varnish type material, the melting point of which is less than quartz transition point (573<sup>9</sup> θ) · θ The drawing shows, in a single figure, a section of a floor element with which it can be used in the construction of double floor according to the present invention.
In figure (1), the designation of the ceramic material cover plate (2) as a whole is a core layer (3) made of a resistant material.

bending light weight per square meter and a thin lower layer (4) with a high tensile strength.
In the chosen embodiment, the core layer is comprised of a bee-nest ceramic body, the opening of which is called (p) ·
