Longitudinal prestressed tendon rapid strand pulling device and method for highway continuous beam
The invention discloses a longitudinal prestressed tendon rapid strand pulling device and method for a highway continuous beam. The device comprises an inner guide pulley (1), an outer guide pulley (2), a positioning guide pipeline (3) and a tensioning device. The positioning guide pipeline is embedded in the box wall of a continuous beam (5), one end of the positioning guide pipeline is inserted into a continuous beam box chamber, and the other end of the positioning guide pipeline extends out of the continuous beam. The inner guide pulley is arranged on the inner wall of a box chamber of the continuous beam, the outer guide pulley is arranged on the beam surface of the continuous beam, and the inner guide pulley and the outer guide pulley face the two ends of the positioning guide pipeline; one end of a longitudinal prestressed tendon (6) is arranged in the box chamber of the continuous beam, the other end of the longitudinal prestressed tendon penetrates through the box wall of the continuous beam through a positioning guide pipeline, and the longitudinal prestressed tendon winds around the inner guide pulley and the outer guide pulley; and the tensioning device is arranged above the continuous beam and is connected with the longitudinal prestressed tendons. According to the invention, rapid penetration and tensioning construction of the longitudinal prestressed tendons of the highway continuous beam can be assisted.
本发明公开了一种用于公路连续梁的纵向预应力筋快速穿束装置及方法，该装置包括内导向滑轮(1)、外导向滑轮(2)、定位导向管道(3)和张拉装置；定位导向管道嵌在连续梁(5)箱壁中，定位导向管道一端插入在连续梁箱室内，定另一端延伸至连续梁的外部；内导向滑轮设在连续梁的箱室内壁上，外导向滑轮设在连续梁的梁面上，内导向滑轮和外导向滑轮面向定位导向管道的两端设置；纵向预应力筋(6)一端装在连续梁的箱室内，纵向预应力筋另一端通过定位导向管道贯穿连续梁的箱壁，且纵向预应力筋绕经内导向滑轮和外导向滑轮；张拉装置设置在连续梁的上方并与纵向预应力筋连接。本发明能辅助公路连续梁的纵向预应力筋的快速穿设和张拉施工。
