Prestressed tendon tensioning system of broken line pre-tensioning beam and construction method
The invention discloses a prestressed tendon tensioning system of a broken line pre-tensioning beam and a construction method. The tensioning system comprises an upper-layer tensioning bottom plate and a lower-layer tensioning bottom plate. An upper prestressed tendon is arranged on an upper-layer tensioning bottom plate, a lower prestressed tendon is arranged on a lower-layer tensioning bottom plate, an upper beam inner steel beam bending device is arranged at the bending position of the upper prestressed tendon, a lower beam inner steel beam bending device is arranged at the bending position of the lower prestressed tendon, and a first tensioning counter-force device is arranged at the bottom of the upper-layer tensioning bottom plate. The first tensioning counter-force device provides tensioning counter-force for the steel beam bending device in the upper beam and the steel beam bending device in the lower beam, and compared with the prior art, the device is simple in structure and low in cost, and can be completely reused.
本发明公开了一种折线先张梁的预应力筋张拉系统及施工方法，其中张拉系统包括上层张拉底板和下层张拉底板；在上层张拉底板上设置上预应力筋，在下层张拉底板上设置下预应力筋，上预应力筋折弯位置设置上梁内钢束弯起器，下预应力筋折弯位置设置下梁内钢束弯起器，且在上层张拉底板底部设置第一张拉反力装置，所述的第一张拉反力装置分别对上梁内钢束弯起器和下梁内钢束弯起器提供张拉反力，相对于现有技术，结构简单，成本低，且装置完全可以重复利用。
