Steel structure roof of Wuyuanhe Gymnasium in Haikou, radiating fish-bellied truss structure roof


The Wuyuanhe Gymnasiumsteel structure roof of Wuyuanhe Gymnasium adopts a radial fish-belly truss structure with a maximum height of 45 meters. “Steel structure is the top priority of this project, and the construction of the project is difficult, mainly in terms of large span, large volume, and many special materials. “The project leader Chen Xiandao introduced that after careful organization and design by the project department, and with the cooperation of all parties involved in the construction, the steel roof structure began to be hoisted on July 25 last year.

“Affected by the epidemic, the procurement and logistics of steel structure raw materials in the first half of last year was delayed. In the later period, we increased machinery, increased construction personnel, and increased construction time. Under the premise of ensuring project safety and quality, we adopted “5+2” and “white”. +Black “Continuously grabbing the construction period and finally completing the capping of the main steel structure.” According to Guo Guanhai, the production manager of the project, after capping, the next step is to unload the support tire frame.
