High strength nick steel strand wires

The utility model aims at providing a high strength nick steel strand wires is formed by the winding of three steel wire helix, include: indented wire, nick, process wire, first enhancement layer, second enhancement layer and inner steel wire, its characterized in that: the indented wire is provided with three, and the surface of three indented wires all is provided with the nick, and three indented wires are all around same the equidirectional spiral of axis winding, the process wire sets up the inboard of indented wire, the lateral wall of process wire with the indented wire strands each other, and first enhancement layer setting is in the outside of process wire, and inner steel wire sets up the inboard of process wire, inner steel wire's lateral wall with the process wire strands eachother. The utility model has the advantages of simple structure, great increase the intensity of steel strand wires, can make this application range with the prestress wire wider, the normal clear ofengineering is guaranteed
