Problems solved by technology

[0004] (1) Affecting the on-site construction period
The overall installation of the climbing frame often requires the cooperation of structural construction, and it is necessary to suspend the construction of some areas for the installation of the climbing frame, which often leads to a delay in the main construction period
[0005] (2) High risk
Due to the existence of a temporary conversion process, the climbing frame is the most dangerous moment in the installation and disassembly process. Since this kind of construction will lead to multiple disassembly and assembly, there is a huge danger
[0006] (3) Cross-operation, the construction process is complicated, occupies a lot of climbing frame resources, and requires a huge climbing frame assembly site

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] see Figure 1 to Figure 12 , taking the Tianhui Center project as an example, the office building structure of this project has three variable sections, and each variable section is retracted by 1300mm through two-story inclined columns. The integrated lifting operation platform 2 adopts the processing measure of pulling the frame inward. The cantilevered steel beam 1 is welded by channel steel with a length of 3.0m of the corresponding strength type according to the design requirements. The hoist 4 is connected between the floor 3 and the integrated lifting operation platform 2 to lift the integrated lifting operation platform 2. When the integrated lifting operation platform 2 climbs to the non-variable section, loosen the floor 3 at the non-variable section. The bolts for fixing the cantilevered steel beam 1 are fixedly connected to...

Abstract

The invention discloses an ultrahigh building variable-section integrated lifting operation platform retraction construction method. The method includes: fixing an overhung steel beam on a floor slab; lifting an integrated lifting operation platform; when the integrated lifting operation platform climbs to a non-variable section, loosening a bolt for fixing the overhung steel beam on the floor slab at the non-variable section, and fixedly connecting the front end of the overhung steel beam with the integrated lifting operation platform; adopting another hoist connected between the floor slab and the integrated lifting operation platform to inward pull the integrated lifting operation platform for several times to pull the integrated lifting operation platform in place, and fixedly mounting the integrated lifting operation platform after being pulled in place on the floor slab at the non-variable section.

Description

technical field [0001] The invention relates to an inward construction method of an integrated elevating operation platform, in particular to an adducting construction method of an integrated elevating operation platform when the external building outline of a super high-rise building needs to be changed in section due to its shape. Background technique [0002] In super high-rise buildings, it is often necessary to retract the external frame columns through slanted columns due to the architectural shape, but at present, super high-rise buildings often use an integrated lifting operation platform, which poses a challenge to how to carry out lifting when constructing this variable section. Here comes the difficulty. [0003] At present, the method of replacing the climbing frame is generally adopted at the construction site for adduction, that is, the climbing frame in the adduction area is stopped at the variable section, and the climbing frame is reassembled at the lower pa...
