Embodiment Construction

[0065] Such as figure 1 As shown, the space curved steel structure pipe truss roof installation construction method of the present invention comprises the following steps:

[0066] The first step: construction plan evaluation:

[0067] Before the official construction, the MIDAS software was used to simulate the construction plan in the non-linear construction stage. The stress and strain of each component during the construction process were investigated through the simulation, so as to evaluate the safety of the construction plan. The construction phase can only be entered after the simulation evaluation confirms that the construction plan is safe. During the construction stage, the stress and strain monitoring of the main components should be carried out according to the simulation analysis results.

[0068] The second step: construction preparation:

[0069] To level the road and installation site, the road for the crane to travel must be flat and solid, and steel subgr...

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...
