Installation method of large-diameter circular roof pipe truss

Abstract

The invention provides an installation method of a large-diameter circular roof pipe truss. The installation method comprises the following steps that step 1, construction fixing of a plurality of concrete foundations is carried out in the center of an installation site of the large-diameter circular roof pipe truss according to the design position; step 2, repetition measurement, labeling and recording of position coordinates and elevation are carried out on the concrete foundations; step 3, temporary supports are set up on site and fixed with the concrete foundations one to one respectively;step 4-5, hoisting and welding of an inner ring truss and outer ring truss of a center circle of a circular roof are carried out; step 6, trusses 12 are symmetrically arranged in sequence, and main truss welding is carried out; step 7, installation welding of secondary trusses, supporting rods and riding tracks is carried out; step 8, the pipe truss is integrally disassembled, and it is detectedwhether or not the deflection under the pipe truss meets the requirement; step 9, the temporary supports are disassembled, and site formation is recovered. The installation method of the large-diameter circular roof pipe truss has the advantages that the rapid installation of the large-diameter circular roof pipe truss is achieved, the splicing efficiency is improved, and the splicing quality is ensured.

Description

technical field [0001] The invention belongs to the field of installation methods of large-scale pipe trusses, and in particular relates to an installation method of large-diameter circular roof pipe trusses. Background technique [0002] At present, in the hoisting process of pipe trusses in large stadiums, railway stations, terminal buildings and other large venues, the traditional method of installing temporary tire frames requires a lot of auxiliary materials, requires high mechanical performance for hoisting, and the auxiliary structure is complex and dangerous. The construction cost is high. Therefore, it is necessary to design a relatively simple and stable installation method for large-diameter circular roof pipe trusses to improve construction efficiency, reduce fabrication difficulty and construction cost, and ensure construction safety. Contents of the invention [0003] For the problems existing in the prior art, the technical scheme adopted by the present inve...
