Combined-type large-load self-climbing cylindrical structure construction platform and construction method

Abstract

The invention discloses a combined-type large-load self-climbing cylindrical structure construction platform and a construction method and belongs to the technical field of super high-rise major structure construction equipment. The combined-type large-load self-climbing cylindrical structure construction platform and the construction method are used for solving the problem that the super high-rise cylindrical structure construction equipment is low in safety and weak in bearing capacity. The construction platform comprises a frame and a pile-loading platform body; the frame is divided into an upper construction section and a lower climbing section, and the pile-loading platform body comprises an upper main pile-loading platform body and a lower vice pile-loading platform body; a platform girder of the upper main pile-loading platform body is connected with a girder of the upper construction section through a bolt, a platform girder of the lower vice pile-loading platform body is connected with the girder of the upper construction section through a bolt, and a template system is suspended onto an extending mold suspending girder of the frame through a chain block; the lower climbing section adopts hydraulic power, uses a core-tube wall body embedded part as a fixed point and drives the upper climbing section to upwards climb along a guide rail, after climbing in place, supporting legs of a bearing steel girder are deepened into a reserved hole of a core-tube wall body, at this moment, climbing is finished, and construction of the corresponding layer core-tube wall body is started.

Description

technical field [0001] The invention relates to the technical field of super high-rise main structure construction equipment, in particular to a combined large-load self-climbing cylindrical structure construction platform and a construction method. Background technique [0002] For the construction of super high-rise structural cylinder structures, tube formwork, integral steel platform formwork system or hydraulic climbing formwork system are now mostly used. However, there are certain deficiencies in the above three forms: first, the bobbin mold needs to be lifted by manpower, and the operator needs to operate inside the formwork during the lifting stage, which is not conducive to the safe operation of workers, and the bobbin mold cannot be used for larger cylindrical structures Second, the formwork structure of the overall steel platform is complex and the overall structure is huge, which is suitable for the overall construction of the core tube wall, but it is not flexi...
