Key Technologies for Hoisting Construction of Large and Complex Steel Truss Roof
The comprehensive pre-treatment workshop of the Phase Ⅲ project of Shanghai Bioenergy Reuse has a total of 6 steel structure roof units,with a truss span of 53.2 m,a truss height of 4.4 m,and a maximum single truss weight of 27.5 t;The steel truss inspection corridor is a steel truss beam frame system,with a truss span of 35.2 m,a truss height of 2.4 m,and a single truss weight of 17 t.This project has high requirements for steel struc-ture processing,transportation,and installation.The rigorous steel structure transportation and installation plan prepared by the project has verified the lifting conditions of various large components,providing strong guaran-tees for the smooth implementation of the project and providing a reference experience for similar projects.
