后张法预应力筋张拉控制方法

On controlling methods for tension control of prestressing tendon of post-tensioning method

以16 m预应力梁板后张法施工为例,探讨了后张法预应力筋在施工中如何进行张拉控制,分别介绍了张拉工艺流程,机具设备的选择,伸长值的理论计算,实际伸长值的测量等内容,为今后后张法预应力张拉施工提供了经验。

Taking 16 m prestressed beam plate post-tensioning method construction as the example, the paper explores how the post-tensioning method to undertake the tension control in construction, and introduces the tension craft process, the selection of machine equipment, the theory calculation of extension value, the measurement of factual extension value, so as to provide the experience for the future post-tensioning pres- tressed tension construction.
