Abstract
The invention discloses a partially upsetting high-strength steel wire and a preparation method thereof, belonging to the technical field of construction. The local upsetting shape of the steel wire can be spherical, ellipsoidal or other polygonal, and the corresponding longitudinal section shape is circular, elliptical or other polygonal. At other positions near the end of the steel wire or in the middle, after making several local upsettings, the anchoring strength between the steel wire and the anchor can be enhanced, the anchorage length can be shortened, the performance of the component can be improved, and steel resources can be saved. After local upsetting is made on the steel wire, other parts can be installed on the steel wire. After multiple steel wires are partially upset at the same position, a platform can be installed for decoration, office and other occasions. The manufacturing method provided by the invention is to use hydraulic pressure to extrude in the upsetting die of the upsetting machine. The invention can be used for anchor rods, prefabricated concrete components, stay cables and hangers, storage racks and the like.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a locally upset high-strength steel wire and a preparation method thereof. Background technique [0002] At present, steel strands are widely used as prestressed tendons in prestressed components and large structures. The steel hinge wire is made by winding steel wire, and the modulus of elasticity is lower than that of straight steel wire. In addition, the steel wire in the steel strand is relatively thin (diameter ≤ 5.0mm), which is very sensitive to corrosion. Therefore, the linear prestressed tendon should try to use large diameter steel wire. However, the surface of high-strength steel wire is relatively smooth, and the bonding force with the anchor is much lower than that of steel hinge wire. The concave and convex of the scored steel wire is small, and the improvement of the bonding performance is limited. In addition, it is inconvenient to install other parts in ...
