深圳宝安体育场屋盖为轮辐式索-桁结构+膜结构组合形式。屋盖索-桁结构是膜结构的支撑骨架,由上内环索、下内环索、飞柱、外环梁及36片三角形径向索网组成,施工的关键是径向索的整体张拉。钢索数量多、荷载大、工期紧,施工难度非常大。在对各种张拉方案进行仿真模拟计算后,最终确定了先提升上径向索就位,再提升张拉下径向索就位,最后安装悬挂索的张拉方案,并采用计算机自动控制整体张拉系统进行张拉施工。
Shenzhen Baoan Stadium roof spoke cable - truss structure + membrane structure combinations. The roof cable-truss structure is the supporting structure of the membrane structure, which consists of the inner inner ring cable, the lower inner ring cable, the flying column, the outer ring beam and 36 triangular radial cable networks. The key to the construction is the whole sheet of the radial cable Pull. Cable number, load, tight schedule, construction is very difficult. After simulating and calculating various tensioning schemes, the tension scheme of first lifting the upper radial cable and then pulling the radial cable under tension is finally determined, and finally the tensioning scheme of the suspension cable is installed, and a computer automatic control Overall tension system for tensioning construction.
