description

Cantilever slabs protruding from the Hauswarid, as used in particular for balcony floors, are usually made of steel reinforced concrete. This results in very weighty constructions with the required strength requirements. Particular attention must be paid to the risk of corrosion associated with steel reinforcement. Another major disadvantage of these known plates is that, as an element leading from the outside into the interior, they cause considerable heat losses due to the high thermal conductivity of steel-reinforced concrete. Today, this is no longer viable in the general efforts to carefully insulate buildings.

The invention has for its object to provide a cantilever plate which avoids the disadvantages mentioned above. The essential features of the subject matter of the invention result from the patent claim.

An embodiment of the invention is explained in more detail with reference to the drawing.

The cantilever plate shown for a balcony extends cantilevered beyond the house wall 8. The over-concrete 3 of the slab is poured onto a prefabricated, combined goat-concrete slab 1, 2. The latter consists of the clay rib stones 2 and the ceiling beams 1, the latter being reinforced with fiber composite cables 9. Further reinforcements 4 are introduced in the over-concrete 3, wherein a mesh 5 can also be provided as reinforcement. For all these reinforcements 4, 5, 9, fiber composite material cables are preferred! made of aramid or a carbon fiber or glass fiber reinforced (CFCC, GFK) composite material, i.e. in any case a material that, in addition to negligible thermal conductivity, is not subject to corrosion. Depending on the mechanical requirements and the type of material, the reinforcement with pre-stress or slack is used, the former in particular with aramid, the latter with CFCC.

The clay rib blocks 2 are continuous over the entire length of the panel, as are the cables 4 serving as upper armor and absorbing the tensile stress. The design described below achieves thermal separation between the inner and outer panel parts. The over-concrete 3 is divided by an insulation core 6 made of plastic in the area of the house wall 8, and the ceiling beams 1 are divided into two sections by pressure-resistant plastic plates 7. A heat flow from the outside into the interior can therefore only take place through the clay ribs 2 and the reinforcements 4 and 9 consisting of composite material, all of these elements are very poor heat conductors. In order to obtain an underside of the panel consisting of the same material, the ceiling beams 1 can be provided with a clay shoe 10.

Due to the design described, the forces are absorbed by the fiber composite cable 4 at the top in the tension zone, while the pressure zone is formed at the bottom by the clay-brick elements.
