Inside and outside ring-shaped steel structure three-dimensional divergent construction method

Abstract

The invention discloses an inside and outside ring-shaped steel structure three-dimensional divergent construction method and relates to the technical field of building construction. The inside and outside ring-shaped steel structure three-dimensional divergent construction method comprises BIM modeling, determination of a construction thought, partitioning of projection of a horizontal plane of the structure, arrangement of mechanical equipment, radial three-dimensional hoisting, zipper-type close-up sealing and reverse ending of a peripheral area. All steel structure members are processed and prefabricated in a processing plant. When the steel structures are mounted, all the steel members are hoisted modularly. The steel members are mounted by adopting a construction technique of being symmetrical in east-west direction and synchronous in inner and outer loops, partitioning in a gridding shape, arranging in multiple point locations, hoisting radially and closing up in a zipper shape.The construction efficiency is improved greatly, the mounting speed is accelerated, the mounting construction period of the steel structures is shortened obviously, other follow-up professional inserted construction in advance is facilitated, and the inside and outside ring-shaped steel structure three-dimensional divergent construction method has good economical benefit and social benefit and isworth being popularized and applied in similar steel structures.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a three-dimensional divergent construction method of an inner and outer ring-shaped steel structure. Background technique [0002] In recent years, my country's construction industry has developed rapidly and its construction capacity has been continuously enhanced. With the continuous rapid development of the construction industry, the scale of projects is constantly expanding, and the construction methods are gradually changing. In building construction, for the installation of the steel structure of the inner and outer ring-shaped structural system, the traditional installation method is to construct the structure within the ring area first, and then construct the structure outside the ring area, gradually constructing layer by layer from the inside to the outside. [0003] On the one hand, the existing traditional installation method is slow in construction pro...

AI Technical Summary

Problems solved by technology

[0003] On the one hand, the existing traditional installation method is slow in construction progress, and it is difficult to meet the higher requirements of today's quality and construction period, and the construction from the inside to the outside is likely to block the road leading to the interior during the construction of the steel structure, causing other professions to fail. Adding in will lead to the inability to form flowing water construction, resulting in waste of resources. Therefore, we propose a three-dimensional divergent construction method for inner and outer ring-shaped steel structures
