忠县电竞场馆超长主次桁架与环带桁架穹顶钢结构施工技术

Construction Technology of Super Long Main and Secondary Trusses and Belt Truss Dome Steel Structures of Zhongxian E-sports Venues

超长主、次桁架与环带桁架穹顶钢结构的结构形式为主、次桁架与主体钢柱刚性连接,形成稳定空间桁架结构,再通过环带桁架与主、次桁架相互连接,形成了圆弧造型。以简单的桁架+框架结构,实现了空间圆弧形穹顶的设计思路,以忠县电竞场馆项目为依托,介绍了超长主、次桁架与环带桁架穹顶结构的相关施工技术。

Long truss with main and secondary belt steel structure truss dome,its structural style is main and secondary belt with the rigid connection of the main steel column,the stable space truss structure is formed. The belt shape is formed by connecting the girder with the main and secondary truss. With simple truss ＋ frame structure,the design idea of space dome is realized. This paper takes Zhongxian esports venues projects as the backing,mainly introduces the super long truss with main and secondary belt truss dome structure of the relevant construction technology.
