Steel pipe column verticality adjusting device and pile column integrated construction technology by using steel pipe column verticality adjusting device in reverse construction

Abstract

The invention provides a steel pipe column verticality adjusting device and a pile column integrated construction technology by using the steel pipe column verticality adjusting device in a reverse construction technology. Pile column integrated construction in the reverse construction can be met, complicated steel pipe column verticality adjusting and positioning equipment can be omitted, the perpendicularity of a steel pipe column in the reverse construction is dramatically improved, the construction period is shortened, and the project cost is reduced. According to the steel pipe column verticality adjusting device, the structure is simple, adjustment is convenient, the verticality adjusting effect is audio-visual, repeated using can be achieved, the construction cost is effectively reduced, and the economic benefit is dramatically improved; and through organic coordinating working of each built-up section of the verticality adjusting device, it is ensured that the steel pipe column can vertically meet the demands of building design, the safe structure is achieved, and using function is satisfied.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a vertical adjustment device for a steel pipe column in upside-down construction and an integrated construction process for piles using the device. Background technique [0002] At present, with the development of urban construction, high-rise buildings and large-scale public buildings are gradually increasing, but construction in densely built urban areas is restricted by two important factors: the small site and the impact on the safety of adjacent buildings. In order to solve the problem of small site and reduce the impact of foundation pit excavation on surrounding structures, roads and underground pipelines, the reverse construction method has been widely used in construction projects. Compared with conventional foundation pit construction, the upside-down method adopts the method of "replacing columns with piles, supports with slabs, and walls with enclosures", which sa...

Problems solved by technology

However, the installation accuracy control of steel pipe columns has always been a major and difficult point in the construction process control of the reverse method, and the construction difficulty and unpredictability are relatively large.
