摘　　要：在高层建筑装饰装修及砌体结构施工中越来越多的施工单位为了避免地下室顶板开洞过多,会将施工电梯基础放置在地库顶板上,但考虑顶板的承载力不满足要求,故需要对电梯基础下面的顶板进行加固处理,通过对钢管架、工字钢柱、格构柱回顶方法进行受力验算和材料用量对比分析,其结果得出格构柱受力较好且耗材较少。In the decoration and Masonry structure construction of high-rise buildings, more and more construction units will place the construction elevator foundation on the basement roof in order to avoid too many openings in the basement roof. However, considering that the bearing capacity of the roof does not meet the requirements, it is necessary to strengthen the roof under the elevator foundation through steel pipe frame, I-steel column The results showed that the stress of lattice column was better and the consumables were less.
