Novel prestress die-drawing steel strand
The invention belongs to the technical field of metal wires, and particularly relates to a novel prestress die-drawing steel strand. The novel prestress die-drawing steel strand is composed of three steel wires. The sections of the three steel wires are the same in shape and are similar to isosceles triangles with the vertex angles being 120 degrees respectively. The three steel wires form the die-drawing steel strand with the section being an equilateral triangle. The novel prepress die-drawing steel strand has the advantages that gaps among the steel wires are small, and meanwhile the periphery of the prestress steel strand is in a wedge shape and is embedded into concrete, so that the bonding strength of the concrete and the prestres steel strand is large, the concrete is not prone to falling off, the overall extension strength is greatly enhanced, and meanwhile the service life of the steel strand is prolonged.
