Abstract
The utility model discloses an anti-corrosion prestressed steel strand, which comprises a plurality of steel strand wire harnesses, wherein the outer surface of each steel strand wire harness is sprayed with an anti-corrosion coating; the outer surface of the anticorrosive coating is wrapped with first glass fiber cloth; the outer sides of the steel strand wire bundles are integrally wrapped with second glass fiber cloth; the outer side of the second glass fiber cloth is provided with a steel strand jacket. The utility model discloses the surface spraying of steel strand wires pencil has anticorrosive coating, and anticorrosive coating's surface parcel has first glass fiber cloth, and first glass fiber cloth can play the effect of effective protection anticorrosive coating, and then slows down because the mutual friction between the steel strand wires pencil leads to the fact the coming off of anticorrosive coating; and meanwhile, the outer sides of the plurality of steel strand wire harnesses are integrally wrapped with second glass fiber cloth, and the second glass fiber cloth plays a role in stabilizing the steel strand wire harnesses again. Through the stabilizing effect of the first glass fiber cloth and the second glass fiber cloth, the anti-corrosion effect of the steel strand is further ensured.
Description
Technical Field
The utility model relates to a steel strand wires technical field, in particular to anticorrosion prestress wire.
Background
The steel strand is a steel product formed by stranding a plurality of steel wires, and is divided into a prestressed steel strand, an unbonded steel strand, a galvanized steel strand and the like, wherein the most commonly used steel strand is a galvanized steel strand and a prestressed steel strand. Because the directly twisted prestressed steel strand does not have the corrosion resistance, the prestressed steel strand is very easy to corrode and rust, and the service performance is further influenced.
In the prior art, in order to prevent the corrosion of the prestressed steel strands, rubber sleeves are usually sleeved on the prestressed steel strands; or paint is sprayed on the surface of the prestressed steel strand; both the two modes have the technical problem of poor anti-corrosion effect, and the paint layer is very easy to fall off due to mutual friction between the prestressed steel strands in the mode of spraying paint on the surfaces of the prestressed steel strands.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an anticorrosion prestressing force steel strand wires, corrosion resistance is better.
In order to solve the technical problem, the utility model discloses a technical scheme does:
an anti-corrosion prestressed steel strand comprises a plurality of steel strand wire bundles, wherein an anti-corrosion coating is sprayed on the outer surface of each steel strand wire bundle; the outer surface of the anticorrosive coating is wrapped with first glass fiber cloth; the outer sides of the steel strand wire bundles are integrally wrapped with second glass fiber cloth; and a steel strand jacket is arranged on the outer side of the second glass fiber cloth.
Furthermore, the number of the steel strand wire harnesses is 3, the steel strand wire harnesses are arranged in a regular triangle, and the adjacent steel strand wire harnesses are in line contact.
Furthermore, the number of the steel strand wire harnesses is 4, the steel strand wire harnesses are arranged in a quadrilateral mode, and the adjacent steel strand wire harnesses are in line contact with each other.
Further, the anti-corrosion coating is an anti-corrosion resin coating.
Furthermore, the outer side walls of the steel strand wire harnesses are in line contact with the inner side walls of the steel strand jackets.
The utility model has the advantages that:
(1) by adopting the technical scheme, the anti-corrosion coating is sprayed on the outer surface of the steel strand wire bundle, and the first glass fiber cloth is wrapped on the outer surface of the anti-corrosion coating and can play a role in effectively protecting the anti-corrosion coating, so that the falling-off of the anti-corrosion coating caused by the mutual friction between the steel strand wire bundles is slowed down; and meanwhile, the outer sides of the plurality of steel strand wire harnesses are integrally wrapped with second glass fiber cloth, and the second glass fiber cloth plays a role in stabilizing the steel strand wire harnesses again. Through the firm effect of first glass fiber cloth and second glass fiber cloth, the anticorrosive coating of protection at the surface spraying of steel strand wires pencil from this, and then guarantee anticorrosive effect.
(2) The glass fiber cloth is used as an inorganic non-metallic material with excellent performance, has wide raw material source and low cost, has better heat resistance and corrosion resistance, and is not easy to adhere any substance due to non-adhesiveness, so that the glass fiber cloth has better effect of wrapping an anti-corrosion coating.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
An anti-corrosion prestressed steel strand comprises a plurality of steel strand wire bundles 1, wherein each single steel strand wire bundle 1 is formed by twisting a plurality of steel wires together, and an anti-corrosion coating 2 is sprayed on the outer surface of each single steel strand wire bundle 1; the outer surface of the anticorrosive coating 2 is wrapped with a first glass fiber cloth 3; the outer sides of the steel strand wire bundles 1 are integrally wrapped with second glass fiber cloth 4; and a steel strand jacket 5 is arranged on the outer side of the second glass fiber cloth 4.
Further, in order to improve the mutual stabilizing effect of the steel strand wire harnesses 1, the steel strand wire harnesses 1 are provided with 3 steel strand wire harnesses and 3 steel strand wire harnesses 1 are arranged in a regular triangle manner, and adjacent steel strand wire harnesses are in line contact with each other.
Further, in order to improve the mutual stabilizing effect of the steel strand wire harnesses 1, the steel strand wire harnesses 1 are provided with 4 steel strand wire harnesses and 4 steel strand wire harnesses are arranged in a quadrilateral mode and are in line contact with each other.
Further, the anti-corrosion coating 2 is an anti-corrosion resin coating. The anticorrosive resin coating has strong adhesive force, and specifically, the anticorrosive resin coating can be an epoxy resin coating.
Furthermore, the outer side walls of the steel strand wire harnesses 1 are in line contact with the inner side walls of the steel strand jackets 5. This kind of design can be so that have better firm effect between a plurality of steel strand wires pencil 1, and difficult the emergence is removed, reduces because the poor single steel strand wires pencil 1 that leads to of steadiness is undulant.
The utility model discloses a theory of operation:
the utility model discloses the surface spraying of steel strand wires pencil 1 has anticorrosive coating 2, because the surface of anticorrosive coating 2 wraps up first glass fiber cloth 3, first glass fiber cloth 3 can play the effect of effective protection anticorrosive coating 2, and then slows down because the mutual friction between steel strand wires pencil 1 causes anticorrosive coating 2 to drop; meanwhile, the second glass fiber cloth 4 is integrally wrapped on the outer sides of the steel strand wire harnesses 1, and the second glass fiber cloth 4 plays a role in stabilizing the steel strand wire harnesses 1 again.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
