Introduction to FRP anchors
FRP anchors are an emerging new composite material product that replaces metal anchors. Glass fiber is used as the reinforcing material and polyester resin is used as the base material. It is pulled by a special pultrusion machine and solidified under high temperature and high pressure through a preformed mold to form a fully threaded glass fiber reinforced plastic rod. Add the resin anchoring agent tray and nuts to form the fiberglass anchor. Mainly used for tunnel support, surrounding rock surface anchorage and slope anchorage, coal mine tunnel and semi-coal rock tunnel support and various underground engineering support deep foundation pit anchorage.
Characteristics of fiberglass anchors
High strength, tensile strength is better than ordinary steel, even more than twice that of steel anchors of the same specifications, light weight, is the same as steel anchors of the same specifications The / can be cut, easy to cut, does not damage the cutting machine, shearer, safe. The surface is antistatic, self-flame retardant, does not produce sparks, does not conduct electricity or heat, is durable and highly corrosion-resistant, has good durability and strong bonding strength with anchoring agent concrete, and its thermal expansion coefficient is close to that of cement.
It is characterized in that the fiberglass anchor is fitted with a fiberglass nut through an arc toothed thread, and one end of the fiberglass nut close to the fiberglass tray is extended and narrowed to form a neck, and the fiberglass tray is fitted on the neck of the fiberglass nut. The middle section of the fiberglass anchor is a polished rod structure. The utility model has strong tensile, shear and torsional strength, low production cost and good support effect, and can be applied to all special environments that are flammable and explosive.

The diameter and length of fiberglass anchors can be up to meters, and can be customized according to customer requirements.
This kind of fully threaded FRP and other strong anchors have glass fiber content, tensile strength, elastic modulus, failure elongation, thread bearing capacity/each button, and shear strength. It can be widely used for supporting and anchoring of railways, highways, water conservancy and mine tunnel roadbed slope protection. It not only solves the problem of easy corrosion of steel anchor rods, but also greatly improves the tensile strength and anchoring force, reduces labor intensity and reduces support costs.
