Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber anchor rods and relates to a detachable glass fiber anchor rod structure. Background Art

[0002] Anchor rods are the most basic component of tunnel support in contemporary coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dams. As a tensile member that penetrates deep into the stratum, one end of the anchor rod is connected to the engineering structure, and the other end penetrates deep into the stratum. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body. Its function is to apply prestress to the anchor rod.

[0003] In the existing detachable anchor rod structure, when the anchor rod is connected, the two different sections of the anchor rod are connected through a connecting sleeve. Since the inner diameter of the connecting sleeve is larger than the inner diameter of the anchor rod and the outer surface is smooth, this results in a portion of it protruding relative to the anchor rod. This protruding portion has poor stability when connected to the rock layer, and the nuts on the top of the anchor rod are all exposed, which is prone to rust and damage after long-term use.

[0004] Fiberglass anchor is a fiber-reinforced composite material. It uses glass fiber and reinforced resin as the main raw materials, with curing agent, flame retardant and other filling materials added. It is a fully threaded rod body processed by pultrusion, winding and other processes, and is used with tray nuts and anchors. The weight of the fiberglass anchor is only one-fourth of the weight of the steel anchor of the same specification. It has low transportation costs and is easy to install and construct. The product has excellent anti-static and flame retardant capabilities, and does not produce sparks when cut, ensuring the safety of coal mine operations. Utility Model Content
