Prestress compensation anchorage device with monitoring function applied to prestress anchor rod
The invention discloses a prestress compensation anchorage device with a monitoring function applied to a prestress anchor rod. The prestress compensation anchorage device can compensate the prestressof the prestress anchor rod in time and prevent the prestress of the anchor rod from disappearing so as to improve the stability and reliability of the prestress anchor rod and prolong the effectiveservice life of the prestress anchor rod, and meanwhile, can further visually reflect the current anchor rod prestress condition of the prestress anchor rod. The prestress compensation anchorage device comprises an outer side sleeve, an inner side anchoring and pressing rod, a prestress compression spring and a force measuring scale, wherein the first end of the inner side anchoring and pressing rod is inserted into the outer side sleeve, the inner side anchoring and pressing rod and the outer side sleeve can slide relatively, the second end of the inner side anchoring and pressing rod is located on the outer side of the outer side sleeve, and an anchoring rod via hole is formed in the inner side anchoring and pressing rod; a limiting stop block is arranged on the inner wall of the outer side sleeve, and the prestress compression spring is located between the limiting stop block and the inner side anchoring and pressing rod; and the force measuring scale is arranged on the outer side surface of the inner side anchoring and pressure rod.
本发明公开了一种应用于预应力锚杆上的带监测功能的预应力补偿锚具，旨在提供一种能够及时的补偿预应力锚杆的锚杆预应力，避免锚杆预应力消失，以提高预应力锚杆的稳定性和可靠性，延长预应力锚杆的有效使用期限，同时还能够直观的反应预应力锚杆当前的锚杆预应力情况的预应力补偿锚具。它包括外侧套筒；内侧锚压杆，内侧锚压杆的第一端插入外侧套筒内，内侧锚压杆与外侧套筒之间能够相对滑动，内侧锚压杆的第二端位于外侧套筒的外侧，内侧锚压杆内设有锚杆过孔；预应力压缩弹簧，外侧套筒的内壁上设有限位挡块，预应力压缩弹簧位于限位挡块与内侧锚压杆之间；测力标尺，所述测力标尺设置在内侧锚压杆的外侧面上。
