The invention relates to a self-supporting reinforced-concrete shuttering element which receives the floor reinforcement and has one or more parallel load-bearing ribs for the shutteringless production of solid floors. The aim of the invention consists in reducing the amount of steel used while maintaining the same load-bearing capacity as monolithic floor structures. The object of the invention is to ensure the complete transmission of shear forces between shuttering element and in-situ concrete, without using reinforcing steel members. This is achieved by frictional locking between load-bearing ribs and in-situ concrete by the width of the load-bearing ribs tapering from both end sides to the centre of the shuttering element, with the result that the casting concrete assumes the shape of a double dovetail, the largest width of which is located in the centre. In the region of the pressure zone, the longitudinal sides of the ribs are stepped corresponding to the taper angle (Figure 1). <IMAGE> |
