Description
Technical field
The utility model relates to metal material anti-corrosion treatment technology, and a kind of steel wires for prestressed concrete rope is provided especially.
Background technology
At present, processing that the steel wires for prestressed concrete rope has nothing further does not usually have Corrosion Protection usually.This steel wire rope is used in general occasion and can be suitable for, but when being used for important or during special occasions (as bridge or chemical plant), then decay resistance must being arranged.
Common solution is just overlapped the last layer protective jacket in the steel wire rope periphery, or is coated with the last layer protective paint at the steel wire rope outer surface.Yet gapped between protective jacket and the steel wire rope, water and air or other Korrosionsmedium enter easily, so the effect of its anticorrosive property is not good.And the protective paint that applies at the steel wire rope outer surface very easily peels off, and makes it lose the protection effect.
People's expectation reaches the better steel wires for prestressed concrete rope of a kind of technique effect.
The utility model content
The purpose of this utility model provides the better steel wires for prestressed concrete rope of a kind of technique effect.
The utility model provides a kind of steel wires for prestressed concrete rope, it is characterized in that: described steel wires for prestressed concrete rope is formed by 3~40 bursts of steel wire articulations, and described articulation becomes outside and/or each burst gaps between steel wires of the steel wires for prestressed concrete rope integral body of integral body all to have corrosion-resistant finishes (1).
Specifically include following two kinds of versions in the described steel wires for prestressed concrete rope preferred content: one, described steel wire rope is formed by one heart yearn 2 and six bursts of sideline 3 common articulations; Its two, described steel wire rope constitutes jointly by the core rope that is positioned at its centre with around 6 strands of steel wires of core rope articulation.
Described corrosion-resistant finishes 1 thickness that is arranged in steel wires for prestressed concrete rope integral outer is that (preferred thickness is 0.5~2mm) to 0.2~3mm.
In addition, one deck sand grains in the described preferably also uniform embedding of corrosion-resistant finishes 1 outer surface that is arranged in steel wires for prestressed concrete rope integral outer.
Preferred content also comprises: per share steel wire is specifically formed by 1~3 layer of common twisting of steel wire in the described steel wires for prestressed concrete rope;
The steel wire rope nominal diameter is 0.6~60mm; The per share steel wire of described steel wires for prestressed concrete rope is formed by 1~3 layer of steel wire articulation; Steel wire number in per share is 1~18.
The version of described steel wires for prestressed concrete rope specifically satisfies one of following two class situations:
One is with reference to the following version of YB/T 5197-2005 standards: 1 * 7 single-strand rope, 1 * 19 single-strand rope, 6 * 7+IWS metal thigh core rope, 6 * 19+IWS metal thigh core rope, 6 * 7+FC fibre core rope, 6 * 19+FC fibre core rope, 6 * 37+FC fibre core rope;
They are two years old, with reference to GB/T 20118-2006 standards, group is respectively 1~16 following structured sort: single-strand rope, 6 * 7,6 * 19,6 * 37,6 * 61,8 * 19,8 * 37,18 * 7,18 * 19,34 * 7,35W * 7,6 * 12,6 * 24,6 * 15,4 * 19,4 * 37.
Further specify: with reference to GB/T 20118-2006 standards, the 3rd group 6 * 19 specifically were divided into two class formation forms during the version of described steel wires for prestressed concrete rope specifically satisfied: 6 * 19 (a), 6 * 19 (b); The 4th group 6 * 37 specifically be divided into two class formation forms 6 * 37 (a), 6 * 37 (b).
The manufacture method of described steel wires for prestressed concrete rope is roughly as follows:
1) launches steel wire rope or directly select for use the single steel wire line to make raw material;
2) the steel wire rope surface cleaning is handled;
3) steel wire rope is preheated.
4) steel wire rope is carried out the electrostatic spraying operation, can adopt the epoxy powder of heavy anti-corrosive properties, high tenacity, high-wearing feature;
5) each strand is twisted together;
6) cured;
7) rope traction that processes is come out, receive winding displacement again.
Compare with existing steel wire rope, the utlity model has following advantage:
1, anti-fatigue performance brilliance: because epoxy coating filled-type steel wire rope skin is with coatings such as epoxy materials, epoxy material has certain thickness, can prevent effectively that the steel wire of steel wire rope and peripheral concrete, cement mortar or other metal from producing CONTACT WITH FRICTION;
2, corrosion resistance brilliance: owing to yet all coated and filled by resistant material between corrosion-resistant finishes filled-type steel wire rope surface and the steel wire, can prevent that steam and corrosive medium from infiltrating, the protection steel wire rope is not corroded;
3, stability in use is good: owing to there is resistant material to fill between the corrosion-resistant finishes filled-type steel wire rope steel wire, effectively prevented the sliding friction between the twisted wire steel wire, improved whole service life;
4, steel wires for prestressed concrete rope described in the utility model and concrete or cement mortar to bond (bonding) performance good: because one deck sand grains in the outer resistant material surface embedding uniformly of corrosion-resistant finishes filled-type steel wire rope, increased the frictional resistance with concrete or cement mortar, can guarantee that corrosion-resistant finishes filled-type steel wire rope and concrete or cement mortar bond together reliably.
The utility model technique effect obviously is better than prior art, and it has foreseeable comparatively huge economy and social value.
