Tension clamping and locking device
The invention discloses a tension clamping and locking device which comprises a sleeve, a bearing sleeve, a gland, a sliding block and a rubber ring. The internal thread of the sleeve is connected to the peripheral surface of the finish-rolled twisted steel; one end of the sleeve radially extends away from the finish-rolled twisted steel to form a ring eave; the gland is positioned above the sleeve and is mounted on the peripheral surface of the finish-rolled twisted steel; a certain space is reserved between the gland and the sleeve for the sleeve to move upwards when the sleeve is stressed; according to the tension clamping and locking device, the sleeve is installed on the peripheral surface of the finish-rolled twisted steel under the action of external force and moves in the stress direction of the finish-rolled twisted steel, and when the displacement height is larger than the height of the sliding block, the sliding block moves to the position below the annular eave of the sleeve under the combined action of resistance of the gland and resilience force of the rubber sleeve; after the external force is removed, the sliding block is clamped below the ring brim of the sleeve, so that the sleeve is prevented from being recovered to the original position, the finish-rolled twisted steel is prevented from being recovered to the original state, and the deformation increment part generated by the finish-rolled twisted steel has tensile stress.
本发明公开了一种拉力卡锁器，包括套筒、承载套、压盖、滑块、橡胶圈；套筒的内螺纹连接在精轧螺纹钢筋的外围表面上；套筒的一端向远离精轧螺纹钢筋径向延伸有环檐；压盖位于套筒的上方且安装在精轧螺纹钢筋的外围表面上；压盖与套筒之间留有一定空间供套筒受力时向上移动；本发明的拉力卡锁器，在外力作用下安装在精轧螺纹钢筋外围表面上套筒随精轧螺纹钢筋受力方向移动，当位移高度大于滑块高度时，滑块受压盖的阻力和橡胶套回弹力共同作用下移动到套筒环檐下方，去除外力后因滑块卡在套筒环檐下方，阻止了套筒恢复原位置和精轧螺纹钢筋恢复至原状态，使精轧螺纹钢筋产生的变形增量的部分具有了拉应力。
