随着经济和建筑技术的发展,超高层建筑逐渐增多,内爬式塔吊是一种常见的大型设备,超高层建筑通常通过建筑电梯井道安装内爬式塔吊,内爬式塔吊的安装和施工具有一定的难度,尤其是后期的高空拆卸更是重中之重。文章通过苏州世茂运河城商业二期8#地块超高层建筑项目的真实案例,阐述在实际拆卸高度将近200 m的高空狭窄屋顶(屋顶上有二层9 m高的钢筋混凝土井字梁构架及沿构架四周1~5 m高的钢结构构架)上,采用经设计改进的10 t小型屋面吊和扒杆组合进行内爬式塔吊拆除工作的过程及施工技术要点。
With the development of economy and construction technology, the number of super high-rise buildings is gradually increasing, and the inner climbing type crane is a common large-scale equipment. The super tall building usually installs the inner climbing type crane through the construction elevator hoistway. The installation and construction of the inner climbing type crane has A certain degree of difficulty, especially in the late high-altitude demolition is the most important. Through the real case study of Suzhou Shimao Canal City Commercial Phase II 8 # super high-rise building project, the paper elaborates on the actual disassembly of a 200-meter high-altitude narrow roof (with two 9-meter-high reinforced concrete beam- Along the framework of 1 ~ 5 m high steel frame around the structure), the use of improved design of 10 t small roof hanging and grilling rod combination of internal climbing tower crane removal process and construction techniques.
