Abstract

The invention discloses an overall lifting construction method of a large complex composite structure steel roof. According to the overall lifting construction method, a lifting support is arranged onthe corresponding position in a house, a composite structure roof (including a truss girder, an annular net rack, a pull rope and a roof secondary girder) is assembled in situ through the ground in the house, truss column house exterior hoisting and composite structure roof assembling are conducted synchronously, after roof system ground assembling and pull rope mounting are completed, ground initial tensioning is conducted, ten lifting power is provided for the roof through a lifting jack and a hydraulic control system, thus the composite structure steel roof is overall lifted and descended,and the lifting jack vertically moves to achieve linear adjustment of the roof truss girder, column joint butting and an overall roof system.

Description

Technical field

[0001] The invention relates to an integral lifting construction method of a large-scale complex composite structure steel roof, which is particularly suitable for the installation and construction of a single system or a combined system composed of a large-span stadium truss, a net frame and a cable structure. The invention belongs to the technical field of building construction. Background technique

[0002] Spatial grid truss, grid and cable structure, as a structural form of large-span spatial structure, is a force-bearing system of spatial composite structure, which is used in large and medium-sized stadiums. At present, the construction method of space grid truss structure mostly adopts the segmented hoisting method.

[0003] For a large-span complex composite structure stadium steel roof, its plane size is 94m in diameter, and the maximum height of the truss structure is 22.72m. There are a total of 18 supports, the angles between the supports are all 200, t...
