Drive device for a movably suspended support structure, formwork system having said drive device, arrangement on a building, and movement method

Abstract

The invention relates to the movement of a support structure (6) for a formwork (10) for concreting a concrete part, which protrudes or projects laterally from a reference edge (2) of a construction element (1) of a building, along the reference edge (2), wherein the support structure (6) is suspended by means of a support device or support rail (5) which is guided movably by means of suspension heads (3). A drive device (16) is designed to move the support structure (6) in the longitudinal direction (x) and has: a base element (30) which is formed integrally with or couplable to the support device and has a cross-sectional contour such that the base element (30) can be guided movably in the longitudinal direction (x) through the suspension heads (3) or can be moved past the suspension heads (3); a motor unit (29) which acts in the longitudinal direction (x) and is installed on the base element (30); and at least one pressing element (17) which is coupled to the motor unit (29) so as to be movable by the motor unit (29) relative to the base element (30) or together with the base element (30) relative to the support device and is designed to project beyond the cross-sectional contour of the base element (30) in order to press against one of the suspension heads (3) when said pressing element is moved by the motor unit (29) relative to the base element (30) or together with the base element (30) relative to the support device.
