Technical field

The present invention relates to the suspension cable of bridge part and suspension cable field of fixtures, specially a kind of zinc-aluminum-magnesium coating main cable strand And its manufacturing method.

Background technique

Suspension bridge is current bridge type most important in the world, has many advantages, such as handsome in appearance, and span ability is strong.Main cable strand It is most important primary structure member on suspension bridge, all bridge floor load require to carry by main push-towing rope.The performance of main cable strand, relationship To service life, the operation security etc. of bridge.It is completed at present and uses zinc-coated wire in the most of suspension bridge founded a capital, Although zinc-coated wire main push-towing rope can reach longer service life, answer according to different environmental conditions and different maintenance measures For bridge especially large bridge, still there is shortcoming on service life.

Summary of the invention

In order to overcome the drawbacks of the prior art, provide a kind of durability is good, cross sectional shape is stable, uniform force, using the longevity Long bridge suspension cable is ordered, the invention discloses a kind of zinc-aluminum-magnesium coating main cable strand and its manufacturing methods.

The present invention reaches goal of the invention by following technical solution:

A kind of zinc-aluminum-magnesium coating main cable strand, including steel tendon, steel tendon are bonded mutually with lateral surface by steel wire strand and are constituted, It is characterized in: further includes anchorage, anchoring material, wire sub-panel and twining package tape, the both ends of steel tendon passes through wire sub-panel set on an anchor respectively In tool, casting anchoring material is in anchorage one end of wire sub-panel and steel tendon to be fixed in anchorage, edge on the lateral surface of steel tendon The central axis of steel tendon successively coats twining package tape；Anchoring material is pltine, constitutes and plates on the lateral surface of the steel wire of steel tendon There is zinc-magnesium aluminum alloy coating.

The zinc-aluminum-magnesium coating main cable strand, it is characterized in that:

The cross section of steel tendon is rectangle or regular hexagon；

Corrugated shaping slice is lined between steel tendon and twining package tape, one piece of sizing of lining on every side of steel tendon cross section Piece, each groove of shaping slice medial surface are bonded a steel wire of steel tendon lateral surface respectively.

The manufacturing method of the zinc-aluminum-magnesium coating main cable strand, it is characterized in that: successively implementing as follows:

1. fixed length: taking several, the steel wire of certain length, zinc-magnesium aluminum alloy coating is coated on the lateral surface of the steel wire, to every A piece steel wire pulled out from turntable carries out tension detection, keeps all steel wire tensions consistent, to guarantee strand system Make precision, the steel wire collection beam forming is constituted into steel tendon, twining package tape is successively coated on the lateral surface of steel tendon, by steel tendon By the length requirement customized cut-off of main cable strand.

2. cleaning: the both ends of steel tendon are crossed liquid and cleans at least 5 minutes with helping, and are then rinsed with clear water with clean quickening liquid, The both ends of steel tendon are dried in the shade keeping away at sunlight again.

Help that cross formula of liquid as follows: by CNH₄Cl:CZnCl₂It is made into solute with mass ratio 7:5 mixing, the solute is dissolved in water It is made into the solvent of 300g/L, the solvent is quickening liquid.

3. filoselle: the both ends of steel tendon being respectively penetrated an anchorage, and guarantee the center of both steel tendon and anchorage Axis is overlapped, and the steel wire that steel tendon is constituted in anchorage is spread out by root, wire sub-panel is installed in anchorage, makes the every steel Silk is embedded in the positioning hole of wire sub-panel one by one.

4. anchoring: the inner cavity of anchorage being preheated to 150 DEG C, cast temperature is 460 DEG C~480 DEG C in melting in anchorage The pltine of state anchors material, then cooling under field conditions (factors) to make anchoring material solidification, and main cable strand is made, finally will be described Main cable strand lopping packaging.

The manufacturing method of the zinc-aluminum-magnesium coating main cable strand, it is characterized in that:

Step 1. when, the gauge of wire Φ is in 5mm~7mm, and the tensile strength of the steel wire is in 1560MPa~2160MPa； The cross section of steel tendon is rectangle or regular hexagon, and shirt has corrugated shaping slice between steel tendon and twining package tape, and steel tendon is horizontal One piece of shaping slice is served as a contrast on every side in section, each groove of shaping slice medial surface is bonded one of steel tendon lateral surface respectively Steel wire.

Zinc-aluminum-magnesium coating is most applied to steel plate prior to last century end, to the identical zinc/aluminum-plated steel plate of thickness of coating and plating zinc-aluminium Magnesium steel plate carries out salt spray test, and comparison discovery, the corrosion resistance of zinc-aluminum-magnesium coating is 8~10 times of zinc-aluminium coating.The present invention Main cable strand is made using zinc-aluminum-magnesium coating wire, and has reformed the system of main cable strand accordingly for the characteristic of zinc-aluminum-magnesium coating Make technique and anchor technique processed, increase the stability of main cable strand cross sectional shape, greatly increases stress between steel wire more evenly, The durability of main cable strand, further improves the service life of main cable strand.

The invention has the following beneficial effects: easy to make, safety and environmental protections, and durability is good, and cross sectional shape is stablized, and stress is equal It is even, the service life of bridge can be effectively improved, construction cost is saved, improves bridge construction benefit.
