Synchronous integral bracket-free formwork hanging construction method for tower beam of cable bent tower
The invention provides a cable bent tower beam synchronous integral support-free formwork hanging construction method, which comprises the following steps of: firstly, assembling a cable bent tower beam profile steel framework, reinforcing steel bars and a bottom formwork, integrally lifting to a mounting height, finely adjusting the distance between two tower columns through a main tower opposite-pulling position adjusting system, and finally, mounting the tower columns in a formwork. The main tower and the cross beams are accurately aligned and connected through the cross beam butting and positioning system, and the cross beam profile steel framework is aligned and connected with the tower column profile steel framework, so that the cross beams are smoothly butted and closed, and the deformation and the tower bottom stress in the main tower construction process are controlled; and then the cross beam profile steel framework and the steel bars are connected with the profile steel framework and the steel bars reserved in the tower column. By improving the construction method, the construction period is effectively shortened, the construction difficulty is reduced, the high-altitude operation risk and the mechanical equipment cost are reduced, the application range is wide, and the economical efficiency and safety of the construction process are greatly improved.
本发明创造提供了一种索塔塔梁同步整体无支架挂模施工方法，先拼装索塔横梁型钢骨架、钢筋和底模，并整体提升至安装高度，通过主塔对拉调位系统微调两个塔柱之间距离，以保证横梁顺利对接合龙及控制主塔施工过程中的变形和塔底应力，并通过横梁对接调位系统，进行主塔和横梁精确对位连接，将横梁型钢骨架与塔柱型钢骨架对位连接，之后将横梁型钢骨架及钢筋与塔柱内预留的型钢骨架及钢筋进行连接。本发明通过改进施工方法，有效缩短工期，降低施工难度，减少高空作业风险和机械设备成本，适用范围广，极大提升施工过程的经济性和安全性。
