Description

Technical Field

[0001] The present invention belongs to the field of core tube construction, and particularly relates to a hydraulic climbing material platform system built in a tower crane in a tube and a construction method thereof. Background Art

[0002] The hydraulic climbing material platform is used for the in-situ climbing formwork construction in the core tube of high-rise and super high-rise buildings. The general structure of the prior art is as follows: it is installed in the wall-attached device on the opposite inner walls of the core tube, and guide rails are penetrated through; the climbing column assembly is installed on the guide rails; the fixed truss and the climbing column assembly are fixedly connected through connecting rods; after several groups of transverse structures are formed, an upper frame and a lower hanging frame are respectively built at the upper chord part and the lower chord part of the transverse structure, and the upper frame and the hanging frame are respectively connected into a whole structure through longitudinal cross beams.

[0003] The prior art can refer to the patent with the publication number of CN206942115U applied by the company, which discloses a horizontally self-adjusting hydraulic climbing material platform, including a wall-attached device, guide rails, a climbing column assembly, a combined truss, an upper frame, and a hanging frame. The climbing column assembly moves up and down on the guide rails, and the combined truss is connected to the climbing column assembly to move up and down together. The upper frame is installed at the top of the combined truss, and the hanging frame is installed at the bottom of the combined truss. Generally, for the convenience of installation and fabrication, the combined truss is fabricated in sections and then assembled, and three to four groups of hydraulic climbing material platforms are arranged in the core tube.

[0004] However, in the core tube construction, the situation of setting a tower crane inside the tube is gradually adopted. As a result, there is a single group of hydraulic climbing material platforms on one side of the tower crane and a double group of hydraulic climbing material platforms on the other side. The platform beam on the single group of hydraulic climbing material platforms can only be fixed on the combined truss in a very short section due to the limitation of the tower crane position. Therefore, there is a potential safety hazard that the structural stability is poor and affects the construction safety. Summary of the Invention
