预应力双拱架预制和提升施工技术

Prefabrication and Lifting Technology of Prestressed Double-arching Frame

从大跨度空间结构预应力工程项目的施工经验出发,结合近期完成的虎牌电气工程预应力双拱架预制和提升施工,简述浙江地区首次采用的超大空间结构预应力构件双拱架预制和整体提升施工应用技术,提出拱架提升施工的安全事项。

Based on construction experience of the long-span prestressed space structures project,combined with recent completion of the Tiger Electric project,the prefabrication and lifting technology of super-large space prestressed doublearching frame is adopted in Zhejiang region for the first time,and safety issues for lifting of the frame are suggested.
