Shanghai-Tong Railway Zhangjiagang Station Local Supporting Project Completed the main structure of the left and right wings of the butterfly-shaped sky curtain

The local supporting project of Zhangjiagang station of Shanghai to Shanghai Railway - butterfly shaped canopy project of passenger distribution area on the west side of the station. The proposed structure is a hyperboloid shell membrane structure with butterfly shaped shape in the square in front of Zhangjiagang high speed railway station in Suzhou, which is divided into four parts: Large wings and small wings.

The steel structure of the project is a single-layer hyperbolic reticulated shell structure system, which is symmetrical in plane. The long span of the large wing is about 50m, the short span is about 25m, the long span of the small wing is about 35m, and the short span direction is about 15m. The top surface of the building is hyperbolic, and the highest elevation of the building is about 17 meters. The total steel consumption is 800 tons, and the total membrane area is about 7000 square meters.

At present, the main structure of the left wing is completed, the secondary steel structure is completed by 80%, and the main structure of the right wing is completed. 3 pieces of left small wing are assembled and welded, 4 pieces of steel castings are assembled and welded, and 3 pieces of steel castings are assembled and welded; The lofting of the right small wing is completed and is being assembled.
