Supporting body anchor rod and supporting body anchor rod with sac
The invention provides a supporting body anchor rod. The supporting body anchor rod comprises an anchor rod body and at least one supporting body sleeved on the anchor rod body. The outer surface of the anchor rod body is provided with an outer rib. The surface, sleeved on the anchor rod body, of the supporting body is provided with inner ribs matched with the outer ribs. The supporting body is used for being sleeved on the anchor rod body and is bitten to the outer ribs. A flexible interlayer is further arranged between the outer ribs of the anchor rod body and the inner ribs of the supporting body. Through deformation of the flexible interlayer, the bite force of the supporting body on the anchor rod body can be increased, and stress concentration possibly generated between the supporting body and the anchor rod body during drawing of the anchor rod is reduced or avoided; meanwhile, resistance force acting on the supporting body and a grouting body can tend towards equilibrium, the anchoring strength of the anchor rod is substantially improved, and the using effect and safety of the anchor rod are reliably ensured. The invention further provides the anchor rod with a sac. The sacis arranged at the lower end of the anchor rod body. The diameter of an anchoring section of the anchor rod is increased, and the pulling resistance of the anchor rod is further increased.
本发明提供了一种承载体锚杆，包括锚杆杆体和至少一套合于锚杆杆体的承载体，所述锚杆杆体外表面具有外肋纹；承载体与锚杆杆体的套合面上具有与外肋纹匹配的内肋纹，用于承载体套合于锚杆杆体并与外肋纹咬合；在锚杆杆体的外肋纹与承载体的内肋纹之间，还设置有柔性夹层。本发明利用柔性夹层的变形，可提高承载体在锚杆杆体上的咬合力，降低或避免锚杆拉拔时承载体与锚杆杆体之间可能产生的应力集中，同时可使作用在承载体和注浆体上的阻抗力趋于均衡，使锚杆锚固强度大幅度提高，可靠保证了锚杆的使用效果和安全性。本发明还提供了一种带有囊袋的锚杆，是在上述锚杆杆体的下端设置一囊袋，增大了锚杆锚固段的直径，进一步提高了锚杆的抗拔力。
