Abstract

The utility model discloses an improved structure of a steel strand. The periphery of a wiring harness is plated with a zinc layer at first, and an epoxy resin coating is then coated outside the galvanized layer. The galvanized layer plated on the wiring harness of the steel strand at first can protect the steel strand from corrosion, and the epoxy resin coating coated later can further protect the steel strand from corrosion. Due to the dual protection, the steel strand has higher corrosion resistance.

Description

A kind of steel strand wires improve structure
Technical field
The utility model is about a kind of prestress wire, is meant that especially the good steel strand wires of a kind of corrosion resistance improve structure.
Background technology
At present, the basic structure of prestress wire is to be formed by a heart yearn and several sideline strand system, it does not have Corrosion Protection usually, when using at bridge or other special occasions, need expose fully in the middle of atmosphere as the stressed material beyond the long span building matrix, therefore very easily be corroded and get rusty, influence serviceability.In order to solve foregoing problems, this case applicant once designed a kind of epoxy coating steel strand wires with corrosion proof function, with reference to Chinese patent application number 03140214.3 " epoxy coating steel strand wires and manufacture method thereof " a case, it is to apply the epoxy coating that one deck has corrosion-resistant function in the periphery that has steel strand wires now, this structure can effectively provide steel strand wires with decay resistance, promotes result of use.
Yet, because the stressed lack of uniformity of construction stage, steel structure or rope often are in the contraction or the elongated condition of trace, in the course of time these material surfaces will crack to some extent, because epoxy coating is only attached to the surface of steel strand wires, therefore the position that cracks is easy to the oxidation that is corroded, and reduction of service life, all brings no small trouble to design, construction and the use of this type of building; In addition, in transportation, swiped, also the epoxy coating on surface can be wiped off, expose the steel strand wires of the inside, thereby easy rust corrosion influences result of use, therefore transportation is had relatively high expectations the cost of transportation height as the surface of fruit product.
In view of aforementioned analysis, the design people studies improvement at existing strand structure, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of raising steel strand wires corrosion resistance, and the steel strand wires that improve its service life improve structure.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of steel strand wires improve structure, and wherein: the periphery elder generation plating one deck zinc layer at wire harness is coated with epoxy coating again outside zinc coat.
The described wire harness outside that has epoxy coating also is arranged with a spring-backed quill, and the internal diameter of this spring-backed quill is greater than the external diameter of the wire harness that is coated with epoxy coating.
The described wire harness outside that has epoxy coating also is arranged with inside and outside two-layer spring-backed quill successively.
Above-mentioned spring-backed quill is to use the rubber-moulding technology to make.
After adopting such scheme; because the wire harness of steel strand wires of the present utility model elder generation plating has one deck zinc coat; zinc coat has the etch-proof effect of protection to steel strand wires; be coated with epoxy resin layer again and prevent corrosion to reach further protection steel strand wires, dual protective effect makes the corrosion resistance of steel strand wires stronger.
In addition, by at the sheathed again sleeve pipe in the wire harness outside with epoxy coating, the internal diameter of sleeve pipe is greater than the external diameter of wire harness simultaneously, can be wire harness extendable room is provided, and sleeve pipe is made by elastic material, utilizes its elastic reaction to have prestressing force, backward pull design, shrinks or elongated condition even wire harness is in, can not cause breaking of sleeve pipe yet, increase the service life;
Moreover sleeve pipe externally plays the effect of protection, prevents from the transportation epoxy coating to be caused scuffing, thereby can reduce cost of transportation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Fig. 3 is the structural representation of the utility model embodiment 3.
The specific embodiment
Below in conjunction with drawings and the specific embodiments structure of the present utility model is elaborated.
With reference to shown in Figure 1, the utility model has disclosed a kind of steel strand wires and has improved structure, comprises wire harness 1, zinc coat 2 and coating 3, below introduces respectively.
Wire harness 1 comprises a middle heart yearn 11 and several sideline 12, and described sideline 12 strand is around middle heart yearn 11, and zinc coat 2 is to be plated on wire harness 1 periphery that the strand system is finished, and plays etch-proof effect; Be coated with epoxy coating 3 more again outside zinc coat 2, further play etch-proof effect, this zinc coat 2 makes the corrosion resistance of steel strand wires stronger with epoxy coating 3 double-deck dual protective effects to wire harness 1.
As shown in Figure 2, also be arranged with sleeve pipe 4 with elastic performance in the outside of the wire harness 1 that is coated with epoxy coating 3, and the internal diameter of sleeve pipe 4 is greater than the external diameter that applies the wire harness 1 behind the epoxy coating 3, this sleeve pipe 4 can utilize the rubber-moulding fabrication techniques to form, utilize its elastic reaction, can provide steel strand wires bigger elastic telescopic space, utilize the design of prestressing force, backward pull, make sleeve pipe 4 can not ftracture because of the elongation of wire harness 1; On the other hand, outside sleeve pipe 4 can also play the effect of protection, avoids epoxy coating 3 damaged because of scraping in transportation; prevent that inner wire harness 1 is because of being exposed to the atmosphere corrosion oxidation; reduction is to the requirement of transportation, thus the saving cost of transportation, convenient transportation.
As shown in Figure 3, for improving the protection effect of wire harness 1, can be arranged with inside and outside two-layer spring-backed quill 4,5 successively in wire harness 1 outside that has epoxy coating 3.
In sum, the improvement structure of a kind of steel strand wires of the present utility model focuses on that first plating applies epoxy resin layer 3 after one deck zinc coat 2 is arranged again outside wire harness 1, thereby improves the steel strand wires corrosion resistance, improves its service life.
Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
