Abstract: The invention relates to a support (1) for supporting a structure region, comprising a central part which has a hollow profiled rectangular tube (8) and two end parts (4), wherein each of the end parts (4) is arranged so as to be telescopable out of the central part from open ends (9) of the hollow profiled rectangular tube (8) in order to change the length of the support (1). Each of the end parts (4) has a hollow profiled round tube (2, 3), and inner wall regions (21) of the hollow profiled rectangular tube (8) form guides for the hollow profiled round tubes (2, 3). The hollow profiled round tubes (2, 3) can be guided in the central part in the longitudinal direction of the hollow profiled rectangular tube (8) by means of contact region (22) lying against the guides so as to achieve the telescopability of the end parts (4).

Abstract: 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).

Abstract: The invention relates to a supporting device (14, 14?, 14?, 15, 15?, 15?) for the construction industry. Said device has a fixing element (14a, 15?a) 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; 15?b1, 15?b2, 15?c-15?e) which is connected to the fixing element (14a, 15?a) and, when the fixing element (14a, 15?a) 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; 15?b1, 15?b2) of the cantilever.

Abstract: The invention relates to a lowering system (10) for lowering ceiling formworks (70) during the removal of formworks of a building ceiling, comprising a reciprocating piston (14) and a support base (18), and a locking device, wherein the reciprocating piston (14) is slidably mounted in the support base (18), and can be pushed from an extended working position to a lowered position, and can be locked in the extended position by means of the locking device. The locking device has a pivot bearing and an eccentric lever (16), wherein the eccentric lever (16) is rotatably mounted in the pivot bearing, and the reciprocating piston (14) and the support base (18) are supported against each other in the working position by means of the eccentric lever (16).
