Wuhan Railway Station: Manufacturing Technology of Complex Multi-pipe Intersecting Nodes

Compared with the spherical joint truss structure, the steel pipe intersecting space truss structure is more beautiful and generous. The large-scale use of intersecting trusses started from the construction of Kansai International Airport in Osaka, Japan in 1995. In recent years, some public buildings at home and abroad, such as airport terminals, airports, terminal halls, exhibition halls, and gymnasiums have been widely used. 

There is a big difference between the multi-tube intersecting nodes of the Wuhan Railway Station and the intersecting nodes of other structures. The number of intersecting members of common truss structures generally does not exceed 8, and the intersecting members are obviously divided into primary and secondary members. The number of steel structure intersecting rods in the Wuhan Station is between 6-10, more than 8 pipes intersecting, and the specifications of intersecting elements are relatively close. There is no obvious distinction between primary and secondary, making the production more difficult.

The manufacturing process of the steel structure multi-tube intersecting node of Wuhan Railway Station fills the gap of the lack of mature manufacturing process for the multi-tube intersecting node both home and abroad.
