Rapid installation method for large-span portal frame unit structure
The invention provides a rapid installation method for a large-span portal steel frame unit structure which comprises steel columns located at the four corners and steel frame beams arranged on the steel columns. The steel frame beam comprises two steel beams and tie bars, wherein the two ends of the steel beams are arranged on the steel columns on the two sides respectively, and the two ends of the tie bars are arranged on the two steel beams respectively. According to the hoisting method, the large-span portal frame unit structure can be hoisted in place only through one-time hoisting of one truck crane, lateral deformation of the steel frame beam is avoided in the hoisting process, a stable and good integral structure can be directly formed, the construction efficiency is improved, the cost is reduced, and the risk of high-altitude operation is reduced.
本发明提供了一种大跨度门式钢架单元结构快速安装方法，所述钢架单元结构包括位于四角处的钢柱和设置在所述钢柱上的钢架梁，所述钢架梁包括两个两端分别设置在两侧所述钢柱上的钢梁和两端分别设置在两个所述钢梁上的系杆。本发明能够仅通过一台汽车吊单次吊装即可将大跨度门式钢架单元结构吊装就位，在吊装的过程中钢架梁不会发生侧向变形，能够直接形成一个稳定良好的整体结构，提高了施工的效率，并且降低了成本，降低了高空作业的风险。
