Expandable rock stratum anchor rod
The expandable rock stratum anchor rod comprises a rod body reinforcing steel bar, threads are arranged on the rod body reinforcing steel bar, the middle of the rod body reinforcing steel bar serves as a boundary, the thread directions of the upper end threads and the lower end threads are opposite, a flange is screwed at the upper end of the rod body reinforcing steel bar, an anchoring connecting rod is hinged to the side wall of the flange, and a threaded base is screwed at the lower end of the rod body reinforcing steel bar. A movable connecting rod is hinged to the side wall of the threaded base, and the anchoring connecting rod and the movable connecting rod are connected through a pin. After the expansion type rock stratum anchor rod and a rock stratum are anchored and locked, the bottom of the anchor rod obtains anchoring force, and therefore the anti-pulling capacity of the anchor rod is greatly improved. And a higher pulling resistance effect is obtained while the depth of the designed anchor rod entering a rock stratum is reduced.
本发明公开了一种可扩张式岩层锚杆，包括杆体钢筋，所述杆体钢筋上设有螺纹，以杆体钢筋中间为界，上端螺纹和下端螺纹螺方向相反，杆体钢筋上端螺旋有法兰，所述法兰侧壁铰接有锚定连杆，杆体钢筋下端螺旋有螺纹底座，所述螺纹底座侧壁铰接有活动连杆，所述锚定连杆和活动连杆通过柱销连接。扩张式岩层锚杆与岩层锚定锁死后，使锚杆底部得到一个锚定力，从而使锚杆抗拔能力大幅度提升。在减小设计锚杆的入岩层深度的同时获得更高的抗拔力效果。
