Abstract

The utility model relates to a full-coated steel strand, which comprises a core wire and a plurality of sidings and is characterized in that the circumference of the outer margin of the core wire and the siding of each board is covered with a layer of nonmetal antiseptic made of polyester resin, or epoxy resin or other similar materials, and the coating thickness is from 0.10 mm to 0.24 mm. The outer side of the steel strand is coated with a layer of nonmetal antiseptic or is sheathed with a PE coat. So the steel strand has the advantages of corrosion resistance, good chemical resistance, good waterproof property, excellent impact resistance and good bendability, has the same softness and anchoring property as the ordinary PC steel strands, and is widely used for anchor cables used in operation method without gluing.

Description

Whole coating steel twisted wire

The utility model relates to the member that a kind of prestress engineering is used, and does not particularly have the steel strand wires that bonding worker method is used.

At present, steel strand wires as one of prestress engineering main member, particularly there are not the steel strand wires that bonding worker method is used, for improving its Corrosion Protection, general employing has the plain bar twisted wire of protective jacket PE, or sprays one deck or double layer of metal (referring to Fig. 1, Fig. 2) at the outer surface of its plain bar twisted wire, because gapped between each steel wire of steel strand wires, Korrosionsmediums such as water and air can immerse these gaps from the end, thereby cause the steel strand wires can not be anticorrosion fully.For outer surface sprays the steel strand wires that are coated with a metal level; invar twisted wire stretch-draw etc. are former thereby when making steel wire generation relative displacement; its appearance metal coating is come off and lose protective effect; in addition; because flame sprays the performance that the high temperature that produces can influence steel strand wires during the spray metal, makes mechanical performance variation such as its pliability.

The purpose of this utility model is to provide a kind of outer rim that constitutes each root steel wire of steel strand wires to be coated with the nonmetal anticorrosive coat of one deck all around, and its antiseptic property is good, and does not influence the whole coating steel twisted wire of the original mechanical performance of steel strand wires.

For reaching above-mentioned purpose, the whole coating steel twisted wire of the utility model is formed by a heart yearn and several side line strand system, evenly is coated with the above nonmetal anti-corrosion material of one deck around described heart yearn and each side line outer rim.

Because adopt said structure, the whole coating steel twisted wire of the utility model has the following advantages:

1, corrosion resistance, chemical proofing and water resistance are good;

2, have good resistance to impact, flexible and flexibility and the anchoring identical, solve in transportation and the work progress and be directed at the not corrosion resistant problem of steel strand wires because of the collsion damage steel strand wires with common PC steel strand wires.

3, because the technology of production process is special, the yield strength of these steel strand wires and fracture elongation not only can not reduced, also slightly improve stable mechanical performance.

4, smooth surface, friction loss is few.

Below in conjunction with drawings and Examples, architectural feature of the present utility model is further described.

Embodiment one:

A kind of whole coating steel twisted wire

As shown in Figure 3, these steel strand wires are made of 1,6 side line of heart yearn 2, and heart yearn 1 and each side line 2 outer rim evenly are coated with one deck epoxy coating 3 all around, and coating layer thickness is 0.10mm-0.24mm.

Embodiment two:

The whole coating steel twisted wire of band PE sheath

This kind strand structure is to put a PE sheath 4 again outside embodiment one described whole coating steel twisted wire as shown in Figure 4, is filled with grease or wax 5 between PE sheath 4 and the whole coating steel twisted wire.

Embodiment three:

This kind strand structure is to apply one deck epoxy resin 6 again outside embodiment one described whole coating steel twisted wire as shown in Figure 5, and coating layer thickness is 0.5mm-2mm.

As a kind of conversion of the present utility model: the nonmetal preservative agent that around the outer rim of described steel strand wires or the outside applies can also be the synthetic resin of mylar and so on.
