[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 2As shown, in this embodiment, a high-strength galvanized steel strand for a cable-stayed cable comprises a steel strand body 1, the outer sleeve of the steel strand body 1 is provided with a covering sleeve 2, and a limiting component is provided at the end of the steel strand body 1, and the limiting component comprises a limiting collar 4 sleeved on the end of the steel strand body 1, the inner diameter of the limiting collar 4 is not larger than the outer diameter of the end of the steel strand body 1, the limiting collar 4 is made of metal material, and one side surface of the limiting collar 4 is in a broken shape, and a fixed flange 5 is symmetrically fixed on the outer side of the broken part of the surface of the limiting collar 4, and a first limiting bolt is symmetrically installed on the surface of the fixed flange 5 6. A mounting hole for screwing in a first limiting bolt 6 is provided on the surface of the fixed flange 5. There is a distance between the surfaces of the two fixed flanges 5. A nut is sleeved on the outside of one end of the first limiting bolt 6. A mounting screw hole 7 is symmetrically provided on the surface of the limiting collar 4. A second limiting bolt 8 is screwed into the inside of the mounting screw hole 7. One end of the second limiting bolt 8 extends to the inner side of the end of the steel strand body 1, which is convenient for limiting the end of the steel strand body 1 and preventing the end of the galvanized steel strand from loosening.
