The present invention relates to a construction element consisting of a concrete slab 1, on one side of which wooden transoms 2, which are placed on edge, are fastened. The wooden transoms are anchored in the concrete with metal fastening members 3, 4, which in part are driven into the wood and in part are embedded in the concrete. In order to absorb shearing stresses upon relative motion between the wood and the concrete in case of loads and moisture and/or temperature variations, according to the invention recesses 5 are made in the wooden transoms, which recesses, during casting of the slab, are filled with concrete. The shearing forces are greater at the ends of the wooden transoms than in their middle sections, so that the recesses are expediently disposed fairly close to the ends of the transoms. <IMAGE> |
