摘要
结合一实际工程 ,介绍了无粘结预应力楼盖开洞改造工程的概念设计、计算分析以及后装式组合锚具应用的施工新技术。该技术不需要对预应力钢筋进行二次张拉和对结构进行临时支撑 ,明显节省了施工周期和工程费用。
Based on a project, the new technique of opening reconstruction on the unbonded prestressed concrete slab has been presented,which includes the concept design, construction procedure, and application of post\|assembly anchorage ZM15. Using this new technique, construction time and cost can be cut down obviously.
