Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to an anchor rod positioner and an anchor rod. Background Art

[0002] The rod body of the anchor rod is generally made of materials with high tensile strength such as threaded steel bars, steel pipes, and steel strands.

[0003] The anchor rod has a free section and an anchoring section. The free section can transmit the tension at the anchor rod head to the area of ​​the anchor body, thereby applying prestress to the anchor rod; the anchoring section is the area where the cement slurry bonds the prestressed tendons to the soil layer, which can increase the bonding friction and pressure-bearing effect between the anchor body and the soil layer, and transmit the tension of the free section to the deep soil.

[0004] At present, split positioners are generally used. Most of the existing split positioners need to be used separately according to the needs of each half zone. They need to be locked by nuts when splicing. During this process, the spliced ​​positioners are likely to be scattered and need to be re-spliced. The positioners cannot be pre-positioned when spliced. Utility Model Content
