| Abstract: | The hall light window of a project is steel grid structure with projection area of 1312.2 m2 and arrow height 4.05 m.Both upper and lower chords as well as web members are welded thick-wall square-sectioned pipes while the nodes are of special-shaped cast steel,of which the maximum one is 0.8m by 0.8m.By elaborate organization and rational arrangement of the construction sequence of component fabrication,pedestal installation,high assembly and site weld,good social-economical benefit was achieved. |
