大跨预应力混凝土楼盖施工技术

CONSTRUCTION TECHNOLOGY OF LONG SPAN PRESTRESSED CONCRETE FLOOR

针对部分混凝土建筑中大跨预应力混凝土楼盖施工技术展开研究,依次对安装偏差过大、施加预应力后位移过大问题等相关问题进行综合论述,结合具体工程案例,对该建筑的混凝土楼盖施工技术进行深入分析。同时,对楼盖模板支撑结构的选型与选材任务、大跨预应力混凝土楼盖模板结构计算任务、楼盖结构混凝土浇筑任务,给出全新的施工技术建议,希望可通过新施工技术的有效应用,降低施工过程中存在的安装偏差,进一步实现对大跨度预应力施加后的架构位移控制,全面提升工程建设质量。

This article conducts research on the construction technology of large-span prestressed concrete floors in some concrete buildings,and comprehensively discusses related issues such as excessive installation deviation and excessive displacement after applying prestressing.Combined with specific engineering cases,indepth analysis is conducted on the construction technology of concrete floors in this building.At the same time,new construction technical suggestions are provided for the selection and material selection of the support structure of the floor formwork,the calculation task of the large-span prestressed concrete floor formwork structure,and the pouring task of the floor structure concrete.It is hoped that through the effective application of new construction technologies,the installation deviation problem during the construction process can be reduced,and the displacement control problem of the structure after the application of large-span prestressed concrete can be further achieved,Comprehensively improve the construction quality of the project.
