Prestress low-retraction anchorage device automatic tensioning and locking equipment and tensioning and locking method thereof
The automatic tensioning and locking equipment comprises a tensioning rod (1) and is characterized in that a pressure-bearing cylinder (5) is installed on the outer circumference of the middle of the tensioning rod (1), and a tensioning jack (7) is installed at the upper end of the pressure-bearing cylinder (5); the tensioning end of the upper portion of the tensioning rod (1) penetrates through an inner cavity of the tensioning jack (7) and then is provided with a tensioning nut (2) through external threads, a base plate supporting piece (6) is coaxially fixed to the lower end of the pressure bearing barrel (5), a guide pipe cavity (11) is formed in the base plate supporting piece (6), and an automatic locking device with a telescopic function is coaxially installed in the guide pipe cavity (11). The tensioning and locking device is simple in structure and convenient to use, can automatically tension and lock, can accurately measure displacement and tension value in real time, avoids the situation that the prestressed steel bar is broken during tensioning construction, is safe and efficient in the tensioning process, is high in anchoring efficiency and is small in prestress loss.
一种预应力低回缩锚具自动张拉锁紧设备及其张拉锁紧方法，包括张拉杆（1），其特征在于：所述张拉杆（1）的中部外圆周上安装有承压筒（5），承压筒（5）的上端安装有张拉千斤顶（7），张拉杆（1）的上部张拉端穿过张拉千斤顶（7）的内腔后通过外螺纹安装有张拉螺母（2），承压筒（5）的下端同轴固定有垫板支撑件（6），垫板支撑件（6）的内部为导向管空腔（11），导向管空腔（11）内同轴安装有具有伸缩功能的自动锁紧装置，本发明结构合理，能自动张拉和锁紧，并能实时精确测量位移量和拉力数值，避免了张拉施工时预应力钢棒断裂的情况，张拉过程安全高效，并且锚固效率高，预应力损失小。
