大跨度钢管桁架的施工工艺

Construction technology of large-span steel pipe truss

结合工程实例,从杆件下料、桁架焊接两方面详细介绍了管桁架的制作过程,并从主桁架的吊装、管桁架的滑移两方面对主桁架的吊装进行了阐述,以保证桁架的制作、安装质量,同时可供类似工程参考。

Combined with practical engineering, the author introduces the making process of pipe truss from member cutting and truss welding, and illustrates the hoisting of truss from the hoisting of main truss and the glide of pipe truss, in order to ensure the making and installation quality of truss and offer a reference for similar engineering.
