High-altitude bulk construction method for steel-structure grid

Abstract

The invention discloses a high-altitude bulk construction method for a steel-structure grid. The method comprises the steps as follows: 1), the steel-structure grid is divided into a starting grid and a follow-up grid; 2), a scaffold construction platform is set up at the position of the starting grid, and then construction of the starting grid is carried out by means of the scaffold construction platform; and 3), a constructor carries out the construction of the follow-up grid by considering the starting grid as an operation platform. In the steps above, before construction of the starting grid and the follow-up grid, basic parts such as bolt spheres, chord members and web members are spliced into an assembled unit, and then the assembled unit is hoisted to a construction position, so that splicing construction of the starting grid and the follow-up grid is carried out. According to the method, workload required for setting up a scaffold is reduced; revolving material consumption is low; setting-up time for the scaffold is saved at the same time; and the construction cost is reduced. Besides, the basic parts are spliced into the assembled unit and a high-altitude assembled unit simultaneously, so that the construction progress can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of assembling steel structure grids, and in particular relates to a high-altitude bulk construction method of steel structure grids. Background technique [0002] The steel structure grid is a spatial structure formed by connecting multiple rods through nodes according to a certain spatial grid form. It has simple structure, convenient connection, clear force, high rigidity of the nodes themselves, light weight and beautiful appearance. [0003] There are many installation methods for grids, generally: high-altitude bulk installation, block installation method, high-altitude sliding method, overall hoisting method, etc. Among them, the high-altitude bulk installation method is divided into three types: full support method, partial movable support method, and cantilever method. The process of the full support method is to set up a working platform that is basically the same size as the grid, and the grid is a...
