T-structure continuous beam prestressed steel strand pulling method and strand pulling device thereof
The invention relates to a T-structure continuous beam prestressed steel strand pulling method and a strand pulling device thereof. The strand pulling method comprises the following steps: step 1, arranging steel strands, and installing a strand pulling device; step 2, installing auxiliary traction prestressed tendons; step 3, wrapping and fixing the ends of the whole bundle of steel strands through a connecting sleeve; step 4, connecting and fixing the auxiliary traction prestressed tendons with the connecting sleeve at the end part of the whole bundle of steel strands; step 5, enabling the strand pulling device to pull the auxiliary traction prestressed tendons so as to pull the whole strand of steel strands to penetrate through the T-shaped hole channels; and step 6, dismantling the auxiliary traction prestressed tendons, and fixing the two ends of the whole bundle of steel strands. The strand pulling device comprises a frame, a supporting frame, a steel strand pulling machine and a driving assembly, the supporting frame is slidably connected to the frame, the steel strand pulling machine is slidably connected to the supporting frame in the horizontal direction, the driving assembly is used for driving the supporting frame to vertically slide along the frame, and the device has the effect of improving the strand pulling efficiency of large-span T-structure continuous beam steel strands.
本申请涉及一种T构连续梁预应力钢绞线穿束方法及其穿束装置，穿束方法包括如下步骤：步骤一：整理钢绞线；穿束装置的安装；步骤二：辅助牵引预应力筋的安装；步骤三：通过连接套对整束钢绞线端头进行包裹固定；步骤四：将辅助牵引预应力筋与整束钢绞线端部的连接套连接固定；步骤五：通过穿束装置牵引辅助牵引预应力筋进而拉动整束钢绞线穿过T构孔道；步骤六：拆除辅助牵引预应力筋，对整束钢绞线的两端进行固定。穿束装置包括框架、支撑架、钢绞线穿束机以及驱动组件，支撑架滑动连接于框架上，钢绞线穿束机沿水平方向滑动连接于支撑架上，驱动组件用于驱使支撑架沿框架竖直滑动，本申请具有提高大跨度T构连续梁钢绞线的穿束效率的效果。
