  • Publication number: 20230358060
    Abstract: The invention relates to a self-climbing system (1) for a concrete structural body (2), having a climbing rail (10) and having a climbing unit (12) which is axially movable along the climbing rail (10), wherein a control rod (24) is designed, in predetermined positions (18a, 18b) of a linear drive (18), to apply a torque (D) to at least one of the actuating elements (20, 22). The invention also relates to a self-climbing method.

  • Publication number: 20220307276
    Abstract: The invention relates to a self-climbing system (10) with a self-climbing unit (12) in which the climbing brackets (26) and the working brackets (20) each have anchor receptacles which each correspond with one another in their pattern with respect to their relative positions, with the result that, after freeing the anchor holes (32), which are used by the working brackets (28), of an anchor point (34, 36, 38) of a concrete wall section (14, 16) of a concrete building structure (18), the climbing brackets (26) can be anchored in precisely these freed anchor holes (32) of the anchor point (34, 36, 38). Moreover, the invention relates to a self-climbing unit (12) for an aforementioned self-climbing system (10) and to a method for moving such a self-climbing unit (12) on a concrete building structure (18).

  • Patent number: 11371539
    Abstract: A hydraulic arrangement. The hydraulic arrangement has multiple hydraulic units, the control units of which are connected, in particular in series, via a data connection. The control units are preferably designed to control selectively only hydraulic cylinders directly associated with said units, or also indirectly control, via the data connection and the control unit of an additional hydraulic unit, the hydraulic cylinders associated with said additional hydraulic unit. A climbing formwork having at least one climbing unit, in particular multiple climbing units. The hydraulic units can be linked via the data connection such that synchronous lifting and/or lowering of all climbing units can be or is achieved. The hydraulic units are preferably connected in a master-slave arrangement or are preferably controlled in a master-slave mode. Also preferably, the hydraulic units are designed to switch from the master-slave mode to the stand-alone mode.

  • Patent number: 11359390
    Abstract: A self-climbing system with a self-climbing unit in which the climbing brackets and the working brackets each have anchor receptacles which each correspond with one another in their pattern with respect to their relative positions, with the result that, after freeing the anchor holes, which are used by the working brackets, of an anchor point of a concrete wall section of a concrete building structure, the climbing brackets can be anchored in precisely these freed anchor holes of the anchor point. Moreover, a self-climbing unit for an aforementioned self-climbing system and to a method for moving such a self-climbing unit on a concrete building structure.

  • Patent number: 11105104
    Abstract: A formwork apparatus for producing a wall section in fresh concrete design that includes projecting connection reinforcement elements for connecting a floor to be constructed, comprising a formwork element that includes a support structure and a forming panel supported on the support structure. The formwork element is provided on one of its edge sections with a plurality of edge recesses spaced preferably uniformly apart from one another for the connection reinforcement elements. A single forming board element or multiple forming board elements serve to reversibly cover the edge recesses when the connection reinforcement elements extend through the edge recesses. A method for producing wall sections situated vertically above one another with projecting connection reinforcement elements in fresh concrete design for connecting to a floor.

  • Publication number: 20200332812
    Abstract: The invention relates to a hydraulic arrangement (24). The hydraulic arrangement (24) has multiple hydraulic units (20a, 20b), the control units (26a, 26b) of which are connected, in particular in series, via a data connection (28). The control units (26a, 26b) are preferably designed to control selectively only hydraulic cylinders (16a-16d) directly associated with said units, or also indirectly control, via the data connection (28) and the control unit (26a, 26b) of an additional hydraulic unit (20a, 20b), the hydraulic cylinders (16a-16d) associated with said additional hydraulic unit (20a, 20b). The invention also relates to a climbing formwork (22) having at least one climbing unit (10), in particular multiple climbing units (10). The hydraulic units (20a, 20b) can be linked via the data connection (28) such that synchronous lifting and/or lowering of all climbing units (10) can be or is achieved.
