摘　　要：针对新型装配式高桩码头π形梁板无底板薄壁框架结构预制过程中因箱室内温度高、内模拆除难的问题,对无底板框架结构的预制工艺进行分析,同时引入分体式液压伸缩自动脱模工艺和电热蒸汽养护工艺。结果表明,自动脱模工艺解决了因π形梁板浇注混凝土后内腔温度高无法进行人工作业的难题;电热蒸汽养护工艺压缩构件起吊所需龄期,节约模板用量,提高预制效率。The thin-walled frame structure without a bottom plate ofπ-shape beam plate for a new prefabricated high-piled wharf faces high temperatures in box rooms and difficult inner mold removal during the prefabrication process.In order to solve these problems,this paper analyzes the prefabrication process of the frame structure without a bottom plate and introduces the split-type hydraulic telescopic automatic demolding process and the electric steam curing process.The results show that the automatic demolding process solves the problem that manual work cannot be carried out due to the high temperature in the inner cavity after concrete pouring of theπ-shape beam plate.The electric steam curing process can compress the age required for lifting components,save the amount of formwork,and improve the prefabrication efficiency.
