Construction method for suspended building structure

Abstract

The invention discloses a construction method for a suspended building structure. The method comprises the following steps that S1, a peripheral core tube bearing platform foundation region is excavated, a peripheral core tube bearing platform foundation is constructed at the foundation region, and a vertical load-bearing structure is installed on the core tube bearing platform foundation; S2, a support jig is erected at a position, outside the core tube bearing platform foundation, of the foundation region; S3, a roof truss is installed above the support jig and the vertical load-bearing structure, and the support jig is removed after the roof truss is installed; and S4, a floor steel structure is installed below the roof truss from top to bottom in a layer-by-layer mode. According to themethod, construction is carried out by obeying the structure stress sequence, actual deformation and stress conditions of the suspended structure are convenient to obtain, the structure safety in theconstruction process is ensured, the construction flow and a hoisting process are optimized, a construction site is fully utilized, the construction cost is reduced, the construction efficiency is improved, moreover, the construction quality is ensured, and the method can be widely applied to construction of the suspended structure.

Description

technical field [0001] The invention relates to the technical field of building structure construction, in particular to a construction method of a suspended building structure. Background technique [0002] The suspended structure is a new structural system formed by using four corner core tubes as the vertical load-bearing structure, and the load of the floor structure is transmitted to the above-mentioned vertical load-bearing structure through suspenders and long-span trusses. This structure can often realize the formation of an open free space on the ground floor of the building, which is easy to meet the requirements of large spaces. [0003] For the construction of the steel structure of the floor, the traditional method adopts the bottom-up reverse construction method. This construction method is opposite to the stress principle of the suspension structure. It needs to be supported by the support frame throughout the whole process, which makes the construction measur...

[0003] For the construction of the steel structure of the floor, the traditional method adopts the bottom-up reverse construction method. This construction method is opposite to the stress principle of the suspension structure. It needs to be supported by the support frame throughout the whole process, which makes the construction measures complicated and affects the construction progress; Moreover, when the supporting tire frame is removed, due to the instantaneous release of the load, it is easy to cause structural deformation
