Abstract

The invention discloses a monofilament-coated epoxy coating zinc-plating prestressed steel strand. The monofilament-coated epoxy coating zinc-plating prestressed steel strand comprises a support column, a middle roller and a winding rod. A top end of the support column is fixedly welded with a cross rod, and the left and right sides of a top end of the cross rod are fixedly welded with blocking strips. An inner end of the blocking strip is sheathed with an installing plate. A top end of a reset spring is provided with a buffer rod. The winding rod is fixedly stuck on an inner wall of a fixingplate. The middle of the interior of a steel strand outer housing is provided with a main steel wire, and two head and tail ends of the steel strand outer housing are sheathed with first gear mechanisms. In a process of conveying the monofilament-coated epoxy coating zinc-plating prestressed steel strand, a threaded rod is fixedly connected between the installing plate and the fixing plate, so that the fixing plate is avoided to be leftwards and rightwards moved and shaken in the conveying process, and stability performance of the winded steel strand can be guaranteed. In addition, in a process of using the steel strand for working, the installing plate and the fixing plate can be detached.

Description

technical field

[0001] The invention relates to the related technical field of steel strands, in particular to monofilament-coated epoxy-coated galvanized prestressed steel strands. Background technique

[0002] The prestressed steel strand is a stranded steel cable composed of 2, 3, 7 or 19 high-strength steel wires, and has been subjected to stress relief treatment, that is, stabilization treatment, suitable for prestressed concrete or similar purposes, the prestressed steel strand The main features are high strength and good relaxation performance. In addition, it is relatively straight when unfolded. The common tensile strength level is 1860 MPa, and there are also strength levels such as 1720, 1770, 1960, 2000, and 2100 MPa. The yield strength is also very high. It is made of high-carbon steel wire rod, which is cold-drawn into steel wire after surface treatment, and then a certain number of steel wires are twisted into strands according to the steel strand structure, a...
