Key Construction Technology for Permanent Protection Steel Structure of a Site
A site protection project adopts a steel structure greenhouse in the form of arch+cantilever,which has an ultra-long cantilever with a span of 45m.This article analyzes the refined construction of the steel structure and determines the key points for controlling the construction process of each key link.After the main arch is assembled on the ground,it rotates in place in the air and forms a complete force system with the supporting arch.The remaining members are installed in a scattered manner,and the installation difficulty is reduced by setting temporary support bed-jig.MIDAS Gen was used to simulate and analyze various major construction processes,ensuring the safety and convenience of the construction process,improving installation efficiency,effectively protecting the original site during the construction process,and reducing interference.
