Combined prestressed anchorage device
The invention relates to the technical field of air detection and monitoring, in particular to a combined prestressed anchorage device which comprises a shell, a supporting rod is fixedly connected to the lower portion of the inner side wall of the shell, a corrugated pipe is fixedly connected to the lower end of the supporting rod, a threaded rib is fixedly connected to the lower end of the shell, and a round hole is formed in the top of the shell. A threaded cylinder is slidably connected to the inner side wall of the round hole, a clamping piece is movably connected to the upper end of the threaded cylinder, a sleeve is connected to the outer side of the threaded cylinder in a threaded mode, cavities are formed in the left side and the right side of the interior of the threaded cylinder, and limiting rods are fixedly connected to the positions, located at the lower ends of the interiors of the cavities, of the interior of the shell. After the clamping piece enters the threaded cylinder, the sleeve is rotated to drive the threaded cylinder to move upwards, the prestress lost when the clamping pieces move inwards when the clamping piece is recycled can be supplemented, the prestress can reach the set ideal preset value as much as possible, and the possibility that a building is damaged due to the fact that the prestress does not reach the standard in the later period is avoided as much as possible.
本发明涉及空气检测监控技术领域，具体为一种组合式预应力锚具，包括外壳，所述外壳的内侧壁下部固定连接有支撑杆，所述支撑杆的下端固定连接有波纹管，所述外壳的下端固定连接有螺纹筋，所述外壳的顶部开设有圆孔，所述圆孔的内侧壁滑动连接有螺纹圆筒，所述螺纹圆筒的上端活动连接有夹片，所述螺纹圆筒的外侧螺纹连接有套筒，所述螺纹圆筒的内部左右有两侧均开设有空腔，所述外壳的内部位于空腔的内部下端固定连接有限位杆，在夹片进入螺纹圆筒的内部后，通过旋转套筒带动螺纹圆筒向上移动，可以将夹片回收时向内部移动损失的预应力补回，使预应力可以尽可能达到设定的理想预值，尽可能避免了在后期建筑因为预应力不达标而损坏的可能性。
