Research Review on the Manufacturing Technology of Large-span Spatial Pipe Truss Structures of the Tongling Stadium

Aiming at the large cantilever triangle spatial pipe truss structure system of Tngling stadium, from the perspective of component processing technology, studying of machining technology for complex steel structure components, combining the new steel tube with existing commonly used hydraulic press, the smaller investment in equipment will meet the production requirements. In view of the small curvature angle bend, proposing the more straight pipe shrimp tube instead of the circular arc segment has solved the intersecting node production problems of the two small Angle steel pipes. In this paper, the results for complex pipe truss structure was processed for the future similar structure construction with popularization and application value.
