| 摘 要： | 河南省体育中心游泳跳水馆工程,其屋盖体系由上部组合梁结构、空间索杆体系、玻璃顶结构和悬挑结构组成,因施工条件限制,不能进行整体吊装、滑移就位,通过在张弦梁部位搭设局部钢管胎架,分段拼装就位,现场进行预应力拉索张拉,有效解决了施工难题,节省了工程费用。

| Abstract: | In the swimming and diving hall project of He＇ nan Sports Center, the roof system is composed of upper composite beam structure, space rod-cable system, glass roof structure and cantilever structure. Limited by construction conditions, the roof can neither be lifted as a whole nor be positioned through slippage. Construction difficulties are successfully solved and construction cost is saved through setting local steel pipe jig at the position of beam string structure, segment assembly and positioning, as well as field tensioning of prestressing cable. |
