Abstract：
The roof of Cangzhou Stadium adopts double-twisted spatial steel pipe truss structure, and both main and secondary rods are made of bent pipe, having complex processing technique and large difficulty in assembly. Most part of the steel truss is assembled into integral segments on ground through setting of segment assembly jig, standing assembly jig and horizontal assembly jig. This assembly method could effectively guarantee construction quality, such as assembly and welding, etc.
