FRP (Fiber Reinforce Plastic) rib composite type prestress anchoring device

The invention provides an FRP (Fiber Reinforce Plastic) rib composite prestressed anchoring device, which belongs to the technical field of building construction and comprises an outer anchor ring, and an inverted conical through hole is formed in the outer anchor ring; the steel sleeve is inserted into the conical through hole in a conical shape, and a cavity allowing the FRP rib to penetrate through is formed in the steel sleeve; the end plug and the tail end anchoring device are arranged at the two ends of the steel sleeve respectively, and the FRP rib penetrates through the end plug and then is fixedly connected with the tail end anchoring device; and the bonding medium is filled in the cavity and is used for fixing the FRP rib. Wherein the FRP rib is fixed in the steel sleeve through the bonding medium, so that the problem that the FRP rib is damaged by clamping due to circumferential stress concentration in the tensioning process can be effectively avoided; the steel sleeve is inserted into the conical
