大型钢结构悬挑屋架的施工质量控制

Quality control of case-scale steel structure construction

通过原材料质量控制及焊接工艺技术措施防超厚钢板层状撕裂;采用双塔吊后退吊装工艺,通过过程中的质量控制,完成大跨度悬挑桁架施工,确保钢结构质量和工期。

This article introduces some quality control measures in steel structure, such as preventing thick steel plate from laminar welding crack by raw material quality control and welding technique measures, apples tower cranes with back hoisting technique and process control in installation of large span steel truss and ensures the quality and duration of steel structure construction.
