摘　　要：某32 m大直径钢筋混凝土筒仓仓顶为锥壳结构,常规混凝土筒仓仓顶施工时需搭设满堂红脚手架或中心井架,脚手架搭设难度大、成本高、所需工期长。为解决此类问题,以32 m大直径筒仓仓顶为例提出三种施工支撑平台方案,结合有限元分析,综合考虑工期、成本、周转效率等多方面因素,最终采用贝雷架钢平台结合中心立柱作为仓顶施工的支撑体系。该体系形式简单、受力性能好、周转率高、通用性强,可适用于不同直径筒仓仓顶施工需求,缩短工期,节约成本。The roof of 32m large diameter reinforced concrete silo is a conical shell structure,and the construction of a conventional concrete silo roof requires the erection of a full-scale scaffolding or a central shaft frame,which is difficult,costly and requires a long construction period.In order to solve such problems,three construction support platform solutions are proposed for the 32m large diameter silo roof,combined with finite element analysis,taking into account various factors such as construction period,cost and turnover efficiency,and finally adopting the beryl frame steel platform combined with central column as the support system for silo roof construction.The system is simple in form,with good force performance,high turnover rate and high versatility,and can be applied to the construction needs of different diameter silo roofs,shortening the construction period and saving costs.
