摘　　要：以南京某超高层建筑地下室逆作法项目为例,针对该工程地下室采用钢梁—钢筋桁架楼承板组合楼面结构的特点,逆作施工时钢梁具有长度长、自重大、吊运安装难度大等特点,同时受层高及逆作钢立柱间距的影响,导致机械转运吊装钢梁难度大,进而耽误工期。本研究详细介绍了在地下室逆作情况下钢梁吊运、定位安装以及与钢立柱焊接等施工技术,可为类似工程施工提供参考。Taking the reverse construction of the basement of a super high-rise building in Nanjing as an example,the floor structure of the basement consists of steel beams and steel bar truss bearing plates.Considering the length and weight of steel beams,difficulties in hoisting and installation,and influence of the storey height and steel column spacing in reverse construction,steel beams cannot be transferred and hoisted easily by mechanical means,leading to a delay in construction.In this study,construction technologies for steel beam hoisting,installation and welding with steel columns are introduced in detail,providing a reference for the construction of similar projects.
