Beam string structure roof construction method based on block hoisting and in-situ assembly
The invention discloses a beam string structure roof construction method based on block hoisting and in-situ assembly. The beam string structure roof construction method comprises the steps that a site is reinforced, an offset supporting jig frame is erected, and a limiting baffle is arranged at the top. The large-span beam string structure is assembled on the ground in a module and unit mode and then hoisted, and finally high-altitude in-situ butt joint and assembly of the two sections of beam string structure units are achieved. And after the secondary beam supporting rods and the inhaul cables are installed, the inhaul cables are tensioned, and construction of the beam string structure roof is completed. Splicing and hoisting of the beam string structure are carried out according to modules and units, the position of a welding seam is shifted to the midspan through the shifting supporting jig frame, continuity of the midspan of the beam string structure is guaranteed, transmission of force to the v-shaped supporting rod and the beam string structure during inhaul cable tensioning is optimized, and a limiting baffle and an adjusting short column are arranged at the top. According to the construction method, the deflection, the stability and the safety of the beam string structure in the hoisting, tensioning and unloading processes are controlled, it is guaranteed that the geometric configuration of the beam string structure is more approximate to the ideal state, and meanwhile the construction difficulty is greatly reduced.
本发明公开了一种基于分块吊装原位拼装的张弦梁屋盖施工方法，包括场地的加固和搭设偏移支撑胎架并在顶部设置限位挡板。将大跨度张弦梁分模块、分单元进行地面拼装后吊装，最终实现两段张弦梁单元高空的原位对接拼装。在次梁撑杆及拉索安装完成后对拉索张拉，完成张弦梁屋盖施工。本发明通过分模块分单元进行张弦梁的拼装和吊装，采用偏移支撑胎架将焊缝的位置偏移跨中，保证张弦梁跨中的连续性，优化了拉索张拉时对v型撑杆和张弦梁力的传递，并在顶部设置限位挡板以及调节短柱。本施工方法控制了张弦梁在吊装、张拉和卸载过程中的挠度、稳定性和安全性，以及保证张弦梁的几何位形更近似于理想状态，同时大大减低了施工难度。
