Abstract: A formwork panel for constructing concrete walls having a forming skin supported by a steel frame in which a plurality of holes are provided for receiving a tie rod. The holes are provided with a plastic bushing which extends through and is fastened in the frame. The bushing has a conically tapered bore, the surface of which is continuous and smooth. This makes the removal of concrete from the bore extremely easy (FIG. 3).

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).

Abstract: In a climbing scaffolding or in a climbing formwork a guide rail (11) for the sole purpose of guiding the scaffolding during the lifting and lowering movements is provided, which is detachably secured to the concrete wall by at least two mounting parts (3, 4) for the climbing scaffolding section (6). This allows rapid lifting, and instead of a crane a lifting gear which is supported on the mounting parts can also be used for lifting.
