Installation method of modular steel structure

Abstract

The invention relates to an installation method of a modular steel structure, which comprises the following steps: binding ground beam steel bars and formwork on the foundation to obtain a plurality of foundation cells; tying the cup-mouth steel bars upward at the intersection of the foundation cells and supporting the formwork , get the base of the cup mouth reinforcement cage and the cup mouth reinforcement cage, set the column foot positioning bottom plate and the column foot side wall mounting plate, and then support the formwork; after reviewing the elevation of the column foot positioning bottom plate, pour the ground beam reinforcement cup mouth reinforcement cage with concrete Base, complete the construction of the ground beam and the base of the cup mouth; complete the construction of the floor; put the steel structure column in the cup mouth; install the bottom connecting beam between the steel structure columns to form the first layer frame, and install the beams layer by layer to form Multilayer frame structure. The invention can realize the simultaneous construction of the cup-mouth column foot and the floor, the steel structure column does not need to be divided, the cup-mouth method is used to improve the stability of the steel structure column during the installation process, the installation safety risk is reduced, and the protection difficulty of the finished product is greatly reduced.

Description

technical field [0001] The invention relates to a modular steel structure, in particular to an installation method of the modular steel structure. Background technique [0002] In some factory expansion projects, the main production device needs to use multi-layer steel structure devices, and the underlying equipment needs to be installed in advance, but the on-site installation site is limited and the construction period is short, which brings a lot of inconvenience to the construction. According to the requirements of the steel structure specification, the multi-layer steel structure device needs to be in the form of embedded column feet. If the traditional construction method is used, the following two methods can be used: [0003] 1. After the construction of the pile foundation project is completed, the installation area is excavated as a whole, and then the foundation construction is carried out. After the foundation strength is reached, the steel structure column is i...

But there are also unfavorable situations, for example: the 24-meter-long column is divided into two parts, and the on-site assembly and welding require the precision to be within 3mm, which makes the construction difficult and the risks uncontrollable; it is difficult to protect the finished products of the underlying equipment
