ABSTRACT:
In a formwork panel for concrete walls having a forming skin carried on a steel frame comprising frame pieces extending along the edges of the said forming skin and at least one wedge slide guided on a cross-strut of the said frame, which wedge slide serves to press one end of a bar extending over the joint between two neighboring formwork panels against frame pieces of the said formwork panel, the slide (20) is guided on a cross-strut (5) and has an essentially U-shaped cross-section the legs (22) of which are provided with inwardly extending projections (24) which coact with projections (15) extending laterally from the cross-strut (5) to form a wedge-type connection. The height of the cross-strut (5) is reduced as compared to that of the frame pieces (4) by the value corresponding to the thickness of the cross bar (30) of the slide (20). The slide (20) can be moved into a position in which it does not project during transportation of the panels beyond the surface of the frame opposite the forming plane, and the wedge-type connection is very sturdy. (FIG. 3).
