摘要
鹤壁市体育馆工程为大跨度预应力空间钢管钢桁架结构。分析预应力空间钢管桁架结构受力机理,研究了钢管桁架的拼接、吊装技术和预应力拉索的张拉方法,从而确定了屋盖结构的施工方案。
Prestressed spatial steel pipe truss structure with large span is used in Hebi Gymnasium.The stress mechanism of prestressed spatial steel pipe truss structure is analyzed.The authors study on splicing and hoisting of spatial steel pipe truss,and tension method of prestressed cable,thus the construction scheme of roof structure is determined.
