Special-shaped prestressed steel strand bundle
The invention relates to the technical field of prestress of steel materials used for construction industry, in particular to a special-shaped prestressed steel strand bundle used for a prepressed concrete component. The special-shaped prestressed steel strand bundle comprises a steel strand body, the steel strand body is formed by twisting a center wire and five side wires, wherein the cross-section of the center wire is shaped like a star, the cross-sections of the side wires are all shaped like a triangle, and the cross-section of the steel strand body is shaped like a regular pentagon. The special-shaped prestressed steel strand bundle has the advantages that the seamless connection is adopted between the center wire and the side wires of the steel strand body, so that the steel strand body has stronger cohesive force and is not prone to sliding; meanwhile, the periphery of the prestressed steel strand is shaped like a wedge, the bond stress between the steel strand and the concrete is increased, the quality and the service life of the concrete reinforced structure is improved, and the production cost is reduced.
