谈大跨度异形钢结构正装倒置法施工方法

On right-handed inversion method for large-span special steel structure

结合工作经验,从钢结构材料构件验收、操作平台搭建、单体构件焊接、构件翻转倒置等方面,探讨了大跨度异形钢结构正装倒置施工技术,并总结了该施工技术的特点,为大跨度、异形复杂性钢结构施工提供参考。

Combining with the experience, the paper explores the right-handed inversion method of the large-span special steel structure from theacceptance of the material components of steel structures, establishment of the operation platform , welding of single components, and inversion ofcomponents, and sums up the technical features of the construction, so as to provide some reference for the special long-span steel structure construction.
