摘　　要：某超高层建筑项目主体结构施工的时间长达2年之久,其沉降后浇带采用钢管支撑架时出现钢管生锈、模板和木方腐烂现象,影响支撑的效果,且钢管支撑架长期租赁费用高。介绍一种大直径无缝钢管作为沉降后浇带两侧梁的支撑的做法,避免了小直径钢管架长期租赁,有效解决超高层建筑沉降后浇带支撑的难题。The construction time of the main structure of one super high-rise building project shall last for2years long.When the steel pipe support is used for the construction of settlement post-pouring strap,the corrosions of steel pipe as well as formwork and square wood pillar are easy to occur,which not only affect the supporting effect,but also increase the long-term rental cost of steel pipe support frame.This paper introduces a method of large diameter seamless steel pipe as the support on both sides of the settlement post-pouring strap,which can avoid long-term rent of small-diameter steel pipe frame and effectively solve the difficult support problem in construction of settlement post-pouring strap in super high-rise building.
