Batch circulating tensioning construction method for spoke type cable-supported grid structure
The invention discloses a spoke type cable-supported grid structure batch circulation tensioning construction method. The method comprises the following steps that S1, an operation scaffold is erected, specifically, the operation scaffold is erected at the end, close to a tensioned radial cable, of a prefabricated stand; and S2, tensioning tool equipment is installed, specifically, a set of tool equipment is arranged at the end of each tensioned radial cable, the oil pressure gauge reading consistent with the tensioning force of the radial steel pull rod is calculated strictly according to the calibration record, and the actual tensioning force of the jack is controlled according to the reading. The radial cables of the same batch are tensioned at a time, construction is simple and easy, and tensioning synchronism can be effectively guaranteed; the displacement of key nodes can be strictly controlled by monitoring the support rod deflection amount and the cable length shrinkage amount of each truss of radial cable in real time in the tensioning process; the cable force of each stage and each batch is controlled in real time in the tensioning process, and the cable force after tensioning anchoring can reach the construction analysis theory tensioning force.
本发明公开了一种车辐式索承网格结构分批循环张拉施工方法，包括以下步骤：S1、操作脚手架搭设：在预制看台靠近张拉的径向索端搭设操作脚手架；S2、安装张拉工装设备：在张拉的每根径向索端设置一套工装设备严格按照标定记录计算与径向钢拉杆张拉力一致的油压表读数，并依此读数控制千斤顶实际张拉力。本发明通过单次张拉同批径向索，简单易施工，张拉的同步性可以得到有效保证；通过张拉过程中实时监测各榀径向索的撑杆偏摆量和索长收缩量，可以严格控制关键节点位移；通过张拉过程中实时控制每阶段、每批次的索力，可实现张拉锚固后的索力达到施工分析理论张拉力。
