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 that of ordinary steel, even more than twice that of steel anchors of the same specifications, light weight, and can be cut easily, not the same as steel anchors of the same specifications. Damage to 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 FRP anchor is fitted with a FRP nut through an arc toothed thread, and one end of the FRP nut close to the FRP tray is extended and narrowed to form a neck. The FRP tray is set on the neck of the FRP nut, and the FRP anchor is The middle section 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.

FRP anchor technical parameters
FRP anchor diameter, length up to meters, 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.
