The structure is reasonable, and the full thread of the anchor bolt is of equal strength, which solves the weakness of low strength of the reverse Fried Dough Twists anchor bolt thread and flat place.
Anchor rod is a member system structure for rock and soil reinforcement.By utilizing the longitudinal tensile force of the anchor rod body, the disadvantage of much lower tensile strength than compressive strength of rock and soil can be overcome.
Rock Bolts is a rod-like body anchored to the inside of a rock mass. The use of bolts to support the roadway is to drill holes in the surrounding rock after the roadway is excavated, and then the bolts are installed in the bolt holes to manually reinforce
It can be matched with a high-strength ribbed threaded steel rod body with a yield strength of 500MPa. Compared with cast steel or forged nuts, it can fully exert the performance of anchor rods, Significantly improve the support effect.
