Steel structure modularization construction process

Abstract

The invention relates to modular construction technology for a steel structure, which comprises the following steps: firstly, precisely processing members used by the steel structure in a workshop; secondly, assembling the members into modular assembly units; and thirdly, performing on-scene integral hoisting on the assembled units after assembly by a lifting device, wherein the process of assembling the members into the modular assembly units is completed on the spot, and the process of assembling the on-scene members into the modular assembly units is completed on a group of assembly jigs; and each assembly jig consists of a group of H-shaped steels which are perpendicular to the members and horizontally placed on the ground. The modular construction technology for the steel structure utilizes mature modern large-scale hoisting technology and adopts a modular assembly mode to well solve the problems, is safe and reliable, has high assembly speed, saves machines and tools, is easy to control structural parameters of a size deviation scattering frame, avoids the danger of long-term aloft work, and is ideal novel technology for manufacturing and assembling a large-scale steel structure frame.

Description

technical field [0001] The invention belongs to the steel structure frame of a large factory building and a platform building in the construction field, and in particular relates to a steel structure modular construction technology. Background technique [0002] In recent years, with the development of social economy and productivity, steel structure buildings have developed rapidly due to their small footprint, low overall cost, fast construction speed, easy quality assurance, green environmental protection and many other advantages, and are widely used in factories and high-rise or large buildings. The construction process of the existing steel structure frame is as follows: firstly, the components used in the steel structure are processed in the processing plant; then the components are transported to the construction site and then installed with hoisting tools. For the large-scale steelmaking and mineral processing plants in the metallurgical industry, the steel structu...

AI Technical Summary

Problems solved by technology

For the large-scale steelmaking and mineral processing plants in the metallurgical industry, the steel structure accounts for a large proportion of the building, and the traditional steel structure frame construction technology can no longer meet the construction requirements of this modern super large and super high steel structure frame. During the construction process It shows many shortcomings: 1. The large amount of on-site installation and construction, especially the large amount of high-altitude work, leads to a long construction process; 2. The difficulty of high-altitude work makes it difficult to control the frame structure parameters and installation accurac
