Abstract

The invention provides a removing tool and a removing method of an indoor ultrahigh assembly-type steel structure support system. The tool comprises first removing units and second removing units, which are arranged on the bottom of roof beams at intervals; each first removing unit comprises a non-standard electric hoists and an embedded rigid rail; each second removing unit comprises a winch and a flexible rail; and the first removing units and the second removing units are operated remotely. According to the removing tool and the removing method, a horizontally and bidirectionally sliding and vertically lifting and descending device is adopted, and is matched with a manual pushing and regulating method at the bottom so as to achieve a technical index of removing efficiently and safely, and finally indoor ultrahigh large assembled-type non-standard steel construction elements are removed and lifted efficiently; and the removing difficulty because construction units of the support system are large, high and heavy, and can not be transferred manually and mechanically is solved fully.

Description

technical field

[0001] The invention relates to the technical field of building installation and demolition, in particular to a tool and method for effectively hoisting and dismantling non-standard components of an indoor ultra-high and large-scale assembled steel structure. Background technique

[0002] With the continuous development of industry and construction, there are more and more tall and large space concrete structure projects, especially in large-scale national defense special projects, and this structure has the characteristics of high rigidity and high seismic performance. These ultra-high and large-space reinforced concrete structures have large cross-sections and heavy weights, and the conventional steel pipe formwork support frame cannot meet the construction needs. Therefore, this large-scale assembled steel structure support of "tower column + Bailey frame composite beam" is adopted. system, which is a necessary means to satisfy the construction; after the ...
