摘　　要：为了解决大跨度型钢混凝土高空连廊施工的施工难题,对支撑架体的搭设进行了研究。结合工程实例,参考钢结构搁置主梁的结构形式,通过在已完成结构主体上搭设搁置主梁,下部设置斜撑的形式作为连廊支撑架体的承载平台,经有限元软件受力分析,证实架体能满足此跨度下连廊施工荷载需求及结构设计规范要求,所总结的施工技术可在类似工程中推广应用。In order to solve the construction problems of large-span steel reinforced concrete(SRC)high-altitude corridor,the erection of support frame was studied.Combined with the engineering example,referring to the structural form of the main beam of the steel structure,the main beam is erected on the completed main structure,and the diagonal bracing is set at the lower part as the bearing platform of the corridor support frame body.Through the stress analysis of the finite element software,it is confirmed that the frame body can meet the construction load demand and structural design specification requirements of the corridor under this span.The construction technology summarized in this paper can be applied in similar projects.
