摘 要：在高層建筑裝飾裝修及砌體結(jié)構(gòu)施工中越來越多的施工單位為了避免地下室頂板開洞過多，會(huì)將施工電梯基礎(chǔ)放置在地庫(kù)頂板上，但考慮頂板的承載力不滿足要求，故需要對(duì)電梯基礎(chǔ)下面的頂板進(jìn)行加固處理，通過對(duì)鋼管架、工字鋼柱、格構(gòu)柱回頂方法進(jìn)行受力驗(yàn)算和材料用量對(duì)比分析，其結(jié)果得出格構(gòu)柱受力較好且耗材較少。

Abstract： 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.

在高層建筑施工中，由于地下室層數(shù)較多， 為最大程度上避免在樓層地下室頂板預(yù)留較多、較大的洞口，對(duì)后期封堵洞口、防水施工造成不便，往往施工電梯臨時(shí)基礎(chǔ)會(huì)設(shè)置在地下室頂板之上。（剩余4695字）
