摘　　要：本文以首都医科大学附属北京友谊医院顺义院区建设工程为背景,阐述了高层建筑中分叉钢柱结构的施工技术。该项施工技术能够解决分叉钢柱铸钢节点呈不规则发散、起吊过程易发生翻转、起吊效率低的问题。同时,针对分叉钢柱铸钢节点各分支斜柱较长无法与节点整体吊装、高空对接定位精度及效率低、施焊条件差的问题,提出了一种详细的解决方案。Based on the construction project of Shunyi Branch of Beijing Friendship Hospital Affiliated to Capital Medical University,the construction technology of bifurcated steel column structure in high-rise building is expounded.The construction technology can solve the problems of the irregular divergence of the bifurcated steel column bracket,the flip of the lifting process,and the low lifting efficiency,and so on.In view of the problems of long inclined columns of bifurcated steel column cast steel joints that cannot be hoisted integrated with the joints,low-altitude docking positioning accuracy and efficiency,and poor welding conditions,a detailed solution is proposed.
