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。
Combined with a practical project, this paper introduces the concept design, calculation and analysis of open hole reconstruction project of unbonded prestressed floor and the new construction technology of back-mounted composite anchorage. The technology does not require pre-tensioned steel secondary tensile and temporary support structure, significantly saving construction cycles and engineering costs.
