Problems solved by technology

[0002] At present, in the process of hoisting pipe trusses in large venues such as large stadiums, railway stations, and terminal buildings, 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, so 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

Embodiment Construction

[0032] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described further specifically, as Figure 1-4 As shown, a large-diameter circular roof pipe truss installation method includes the following steps:

[0033] Step 1. In the center of the installation site of the large-diameter circular roof pipe truss, carry out the construction and fixing of several concrete foundations 1 according to the design position of the drawing, and the concrete foundation 1 is used as the support embedded part of the temporary support of the subsequent pipe truss;

[0034] Step 2. Retest the position coordinates and elevation of several concrete foundations 1, and clearly mark them, and fill in the test records;

[0035] Step 3. Set up temporary supports on site and fix them one-to-one with the concrete foundation respectively, retest and locate the elevation and axis of the temporary supports, and mark the positions;

[0036] Step ...

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...
