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.
