The invention relates to a method for displacing a ceiling formwork (10) for a nearest concreting section (9), wherein first (11) and second (12) supporting devices for supporting the ceiling formwork (10) are arranged below the nearest concreting section (9). Said supporting devices each have a shuttering position (EP) and a stripping position (AP), wherein the ceiling formwork is raised to a concreting level in the shuttering position (EP) and lowered relative to the concreting level in the stripping position (AP). The first supporting device (11) is moved into the stripping position and the second supporting device is moved into the shuttering position, and a collision protection element (15, 15) is arranged between the second supporting device (12) and an end face (17, 17) of the ceiling formwork (10) when the end face (17, 17) of the ceiling formwork (10) strikes the second supporting device (12) after passing over the first supporting device (11), so that the collision protection element (15, 15) forms a flank (15a) rising in the displacement direction (VR) for guiding the ceiling formwork (10) in the displacement direction (VR). The end face (17, 17) of the ceiling formwork (10) is then liftedguided by the collision protection element (15, 15)to the concreting level so that the ceiling formwork (10) passes over the second supporting device (12).

The invention relates to a supporting device (14, 14, 14, 15, 15, 15) for the construction industry. Said device has a fixing element (14a, 15a) which rests against a side wall (2a) and is fixed at a fixing point (FP) of the side wall (2a). Said device also has a cantilever (14b1, 14b2, 14c; 15b1, 15b2, 15c-15e) which is connected to the fixing element (14a, 15a) and, when the fixing element (14a, 15a) is in the fixed state, projects from the side wall (2a) such that a load element (10) can rest against a bearing point (AP) of a bearing element (14b1, 14b2; 15b1, 15b2) of the cantilever. The load element (10) can now be displaced in a displacement direction (VR) substantially parallel to the side wall (2a) relative to the cantilever and, when the load element (10) rests against the bearing element of the cantilever, the cantilever is coupled to the load element (10) such that a displacement force component acts on the cantilever in the displacement direction (VR) when the load element (10) is displaced, said displacement force component resulting in a torque on the cantilever. The device also comprises an anti-rotation element (16, 16, 17, 17) which is connected to the cantilever. When the load element (10) is displaced, another end of the anti-rotation element should rest against the side wall (2a) in order to counteract the torque.
