大跨度预应力屋面拱板装配拼装滑移施工技术

Construction Technology of Assembly and Slipping for Large-span Prestressed Roof Arch Plates

以中央储备粮重庆北碚直属库合资建仓项目一标段项目为例,介绍屋面异形拱板、构件模块化预制,装配式施工,高空拼装现浇、顶推滑动就位整套技术,达到节约人工、材料、模板架料,减少垂直运输工程量,装饰装修工序提前进入,提高质量、降低安全隐患,缩短工期,节约成本的目的。

Taking the project of the first section of the joint venture warehouse construction project of the sino-grain warehouse directly under Beibei,Chongqing as an example,this paper introduces the whole process set of special-shaped roof arch plate,modular prefabrication of components,assembly construction,high-altitude assembly and cast-in-place,jacking and sliding in place,so as to save labor,materials and formwork support,reduce vertical transportation,let decoration process in advance,improve quality,reduce safety hazards,shorten the construction period,and save costs.
