摘要
结合实际工程 ,介绍了无粘结预应力楼盖开洞改造工程的概念设计、施工程序、后装式组合锚具的应用等技术要点。该改造工程不需要对预应力钢筋二次张拉和对结构进行临时支撑 ,因而明显地缩短了施工周期并节省了工程费用。
Based on a real project, the new technology of opening\|reconstruction on the unbonded prestressed concrete slab has been presented in this paper, which includes the concept design, construction procedure, and application of post\|assembly anchorage ZM15. Using this new technology, there needs no the second tensioning of the prestressing tendons and temporary braces, thus the construction period and cost can be cut down obviously.
