A drop head of a ceiling formwork has levers (33) connected pivotably to the supporting plate (14) and pivoting outwards as a result of their own weight and possessing locking projections (38). These engage in apertures (39) of engaging profiles (18, 19) on the formwork carriers (16, 17). The insertion of the engaging profiles (18, 19) is not impeded, since the locking projections (38) thereby shift aside. In contrast, separation necessitates a horizontal movement. If a formwork carrier (16, 17) therefore remains adhering to the concreted ceiling, the supporting plate (14) also continues to remain safely connected to the formwork carrier as a result of the interlock. An uncontrolled falling down of formwork carriers is therefore impossible, with the result that the risk of accidents is reduced. <IMAGE> |
