摘　　要：对超高层塔楼内爬式动臂吊拆卸施工技术进行总结,主要通过采用主次塔机交替安拆、增设次塔机基础、主塔机大臂退步滑移拆卸等施工方法,解决了屋顶为多层构架结构超高层塔楼内爬式动臂吊拆卸施工的问题,且提升了拆卸过程的安全性。经过研究得出结论:利用该技术施工可取得良好的效果,施工效率及经济效益突出。This paper summarizes the disassembly construction technology of the internal climbing boom crane in super high-rise towers. By adopting construction methods such as alternate installation and disassembly of the primary and secondary tower cranes, adding the foundation of the secondary tower cranes, and retrograde and sliding disassembly of the main tower cranes, the problems of disassembly construction of the internal climbing boom crane in super high-rise towers with multi-storey roof structures are solved and the safety of the disassembly process is improved. It is concluded that good results can be obtained by using this technology in construction, and the construction efficiency and economic benefits are outstanding.
