The invention discloses a large-span roof steel truss hoisting construction method which comprises the following steps: determining the foundation bearing capacity of a host installation operation site area, selecting a crane model according to the hoisting height, the operation radius and the weight of a hoisted object, and determining a hoisting scheme according to the site condition after selection; calculating a steel wire rope breaking force, and selecting a steel wire rope model according to the steel wire rope breaking force T; and according to the hoisting scheme and the breaking force T of the steel wire rope, a special construction scheme for steel truss installation operation is formulated, steel truss hoisting work is conducted according to the special construction scheme for steel truss installation operation, and welding and paint repairing are conducted after hoisting is completed. Standardized comprehensive hoisting of the large-span roof steel truss of the high-rise building is achieved.

    本发明公开了一种大跨度屋面钢桁架吊装施工方法,包括:确定主机安装作业场地区域的地基承载力,根据吊装高度、作业半径、吊物重量选定吊车型号,选定后根据场地情况确定吊装方案;计算钢丝绳破断拉力,根据钢丝绳破断拉力T选定钢丝绳型号;根据吊装方案、钢丝绳破断拉力T制定钢桁架安装作业专项施工方案,按照钢桁架安装作业专项施工方案进行钢桁架吊装工作,吊装完成后焊接补漆。发明实现了高层建筑大跨度屋面钢桁架的标准化综合吊装。
