Study on the Design Technology of High Sliding Bracket of Triple Steel Truss Arch Roof Cover
The steel roof project of Nanchang East Railway Station is divided into three zones,the roof is a triple steel truss arch,the structure is complex,the maximum height of the sliding bracket is 56 m,the height of the sliding bracket is high,and the load is large.The traditional design based on the symmetrical form of the roof uses a large amount of steel to support,and the construction time is long,which cannot meet the goal of saving and efficient modern engineering.In this paper,based on the structural form of steel roof and the site construction condi-tions,the design of the asymmetric slip support,not only meet the requirements of the slip support construction force,but also save the cost and time limit,to ensure the accurate and safe construction.
