Construction method of prestressed steel pull rod of building daylighting roof
The invention discloses a construction method of a prestressed steel pull rod of a building daylighting roof. The construction method comprises the following steps: S1, checking the steel pull rod; s2, a supporting jig frame in-situ mounting steel structure is erected; s3, setting up an operation platform; s4, mounting a lower chord steel pull rod, hoisting the steel pull rod to a proper mounting position, and connecting a cable head of the steel pull rod with a corresponding cable end node according to a construction scheme; s5, the steel pull rod is tensioned, tensioning equipment is installed, and the steel pull rod is tensioned in batches and stages through the tensioning equipment; s6, the supporting jig frame is unloaded, and the supporting jig frame is dismantled after tensioning is completed; and S7, crossed steel pull rods are installed, and the steel pull rods are additionally installed between the corresponding nodes. According to the construction method of the prestressed steel pull rods of the building daylighting roof, the lower chord steel pull rods are arranged and tensioned, upward equivalent prestressed loads are generated, the internal force state of the structure is optimized, the crossed steel pull rods are used for providing a stabilizing effect after a supporting jig frame is disassembled, and the steel pull rods are installed step by step to ensure that the steel structure is safe and reliable.
本发明公开了一种建筑采光顶的预应力钢拉杆的施工方法，包括以下步骤：S1、钢拉杆检查；S2、搭设支撑胎架原位安装钢结构；S3、搭设操作平台；S4、安装下弦钢拉杆，将钢拉杆吊装到合适的安装位置，按照施工方案将钢拉杆的索头与对应索端节点相连；S5、张拉钢拉杆，安装张拉设备，通过张拉设备对钢拉杆进行分批、分级张拉；S6、卸载支撑胎架，张拉完成后将支撑胎架拆除；S7、安装交叉钢拉杆，在相应的节点之间加装钢拉杆。该建筑采光顶的预应力钢拉杆的施工方法，通过布置和张拉下弦钢拉杆，产生向上的等效预应力荷载，优化结构内力状态，利用交叉钢拉杆在拆卸支撑胎架后为提供稳定作用，分步安装钢拉杆确保钢结构安全可靠。
