Steel strand anchoring structure

The invention provides a steel strand anchoring structure, and belongs to the field of anchoring devices. The anchoring device comprises an anchoring cup arranged at the outer periphery of a steel strand; a support nut for supporting the anchoring cup is arranged on the outer side of the anchoring cup; a clamping piece for tightly pressing the steel strand is arranged on the inner side of the anchoring cup; a protection pipe is arranged at the outer periphery of the steel strand between an anchoring disc and a base; and multiple reinforcing ribs are spirally distributed on the outer side of the protection pipe. The steel strand anchoring structure can adaptively adjust the prestress of the steel strand to prevent the prestress value change of the steel strand caused by stratum creep, steel looseness and structure change so as to enhance the stability of an anchoring system and to guarantee the safety and the stability of buildings and bridges.
