High-altitude construction method for large-span support-free large H-shaped steel beam in narrow space
The invention provides a high-altitude construction method for a large-span support-free large H-shaped steel beam in a narrow space. The high-altitude construction method comprises the steps of pre-embedded plate installation, connecting plate installation, truck crane in-place, hoisting of a large H-shaped steel beam section a, arching of the large H-shaped steel beam section a, hoisting of a large H-shaped steel beam section b, clamping plate installation, small-section square steel installation and high-altitude welding butt joint. Operation safety can be guaranteed, the construction cost is reduced, the construction period is obviously shortened, and efficient building construction is achieved.
本发明提供一种大跨度无支撑大型H型钢梁狭小空间高空施工方法，包括预埋板安装、连接板安装、汽车吊就位、大型H型钢梁分段a吊装、大型H型钢梁分段a起拱、大型H型钢梁分段b吊装、卡马板安装、小截面方钢安装、高空焊接对接。本发明能够保证作业的安全，降低施工成本，明显节约工期，实现高效建造施工。
