摘要

Securing means for load-bearing and for the horizontal and vertical adjustment of concrete facade slabs which are located one above the other and between which an expansion joint remains. In the opposite concrete facade elements there is a mirror-invertedly identical longitudinal recess, the base surface of which is inclined with respect to the horizontal. Two wedge pieces are introduced into the longitudinal recesses, which wedge pieces correspond to the cross-section and whose length only constitutes a portion of the recess in the facade element. An oval recess, directed towards the expansion joint, is located in the wedge pieces. A round metal disc is inserted between the two wedge pieces, which disc exhibits in each case one dowel arranged eccentrically on either side. The dowels of the disc engage into the oval recesses of the wedges. Rotating the disc results, by way of the eccentrically arranged dowels, in horizontal adjustment. Displacement of the wedges results in vertical adjustment. Inadvertent displacement is prevented by the high frictional resistance from the load.
