Spatial curved surface steel structure pipe truss roof installation construction method

Abstract

A spatial curved surface steel structure pipe truss roof installation construction method relates to the technical field of a building construction method. The construction method comprises the following steps of elevating a scheme, making preparation for the construction, measuring and setting out, tidying a pre-buried iron member, setting up an all-around scaffold, checking and accepting a main and secondary trusses, installing the main and secondary trusses, installation ridges and stress sheets, detaching the whole, checking and accepting after main body installation, installing a roof panel plate and checking and accepting the whole. Finite element modeling for a non-linear construction phase can be achieved; construction scheme safety is evaluated according to stimulation check of component stress and strain during the construction, so practical construction can be guided; strain displacement can be monitored during the construction; real-time adjustments can be conducted to components, so construction precision can be improved and building cost can be reduced.

Description

technical field [0001] The present invention relates to the technical field of building construction methods. Background technique [0002] Compared with the usual steel structure, the installation of space curved steel structure pipe truss has a relatively high level of detail in terms of detailed design of components, joint welding of intersecting lines, blanking of irregular roof panels, production and installation of pipe trusses, etc. difficulty. The installation of the traditional space curved steel structure pipe truss has the following disadvantages: 1. The construction needs to build a lot of scaffolding, which is cumbersome, long construction period, and the quality is not easy to guarantee; The quality is not easy to control, the safety assurance of construction personnel is poor, and accidents of falling from heights are prone to occur; 3. The cumulative errors generated during the production and installation of the pipe truss components are relatively large, an...

The installation of the traditional space curved steel structure pipe truss has the following disadvantages: 1. The construction needs to build a lot of scaffolding, which is cumbersome, long construction period, and the quality is not easy to guarantee; The quality is not easy to control, the safety assurance of construction personnel is poor, and accidents of falling from heights are prone to occur; 3. The cumulative errors generated during the production and installation of the pipe truss components are relatively large, and in the end it is often necessary to rework or make larger components. It is time-consuming and labor-intensive to make changes to make the structure close together smoothly; 4. The shape of the space curved roof is complex, and the roof panels are mostly fan-shaped and the shape and size of each fan-shaped panel are different, so it is very difficult to stake out. Inaccurate dimensions, material waste, etc.
