| 摘 要： | 由于近年来预应力结构楼板的普及应用和既有建筑物改造的增加,造成了既有的预应力结构楼板开洞项目的增加.本施工技术充分利用预应力结构的特性,对楼板开洞位置的预应力筋进行放张、切割、二次张拉等工序,通过仅对局部楼板进行加固,保留原有预应力筋的作用,减少了整体加固成本,取得了更好的加固效果.本文详细介绍了既有预应力结构楼板开洞的施工工艺.

| Abstract: | In recent years, due to the popularity of pre-stressed floor structure of the application and use of the building features the transformation of the increase, resulting in the cutting prestressed floor structure of the increase in construction projects. Construction of this technology to make full use of prestressed structural characteristics of prestressed reinforcement for relaxation tension, cutting, secondary tension, only partially through the floor reinforced to retain the role of the tendons, reducin... |
