The invention relates to the technical field of building construction platforms, and discloses a liftable construction platform of an assembly type building and a construction method of the liftable construction platform. The liftable construction platform comprises a working platform horizontally surrounding the periphery of the building, masts used for supporting the working platform, a bridge crane located on the working platform, a concrete spreader installed on the bridge crane, and a net rack located at the top end of the working platform. The working platform is formed by splicing standard joint trusses. The working platform comprises an upper platform body, a lower platform body, truss columns and a climbing system, wherein the upper platform body and the lower platform body are arranged in the mast direction in parallel in a spaced mode; the truss columns are connected with the upper platform body and the lower platform body; and the climbing system is arranged in the truss columns. The side length of the cross section of each truss column is larger than the corresponding side length of the cross section of each mast. Each mast is sleeved with the corresponding truss column. Each mast is formed by splicing standard mast joints. The bridge crane is arranged between two long beams of the upper platform body in a crossing mode. According to the liftable construction platform and the construction method, hoisting equipment is combined with the construction platform, prefabricated members can be arranged in place easily, the position accuracy is high, and the installation efficiency is high.
Description
technical field [0001] The invention relates to the technical field of building construction platforms, in particular to a liftable construction platform of a prefabricated building and a construction method thereof. Background technique [0002] Prefabricated building is a building construction method that uses prefabricated components to quickly assemble and construct on site. Because of its fast construction speed and labor-saving, it has rapidly developed. At present, in prefabricated buildings, prefabricated components are usually hoisted to the working position by mobile or fixed jib cranes. The lifting equipment and the structure of the construction platform are mutually restricted, and it is difficult to position and position the components. It is difficult to adjust the height, elevation and verticality, etc., and the accuracy is poor. The components cannot be placed in place accurately at one time, and there are outstanding problems such as low installation efficie...
