Abstract
The invention discloses a kind of steel wire stay cable preventer and preparation method thereof, including steel wire rope, the outer layer covers of described steel wire rope has polyester band, the outer layer covers of polyester band to have pe sheath, pe sheath is hollow structure, injects noble gas in this hollow structure.Being sprayed directly into steel wire rope surface after being cooled down by air by zinc liquid, play physics covering effect so that the corrosive mediums such as steel wire rope and water and air are kept apart, owing to temperature during spraying is the lowest, steel wire rope will not deform, and its interior mechanics performance is substantially unaffected.Owing to the chemical property of zinc powder is relatively active, electrode potential is lower than steel wire rope, in this corrosion cell; zinc powder is negative pole, and steel wire rope is positive pole, and zinc powder loses electronics; becoming ion to enter to be corroded in dielectric solution, its free electron flows to steel wire rope, makes steel wire rope polarization be protected.This device technique means are simple and easy to do, safe and reliable, easy construction, substantially increase durability and the safety of suspension cable.
Description
Technical field
The present invention relates to bridge protection field, particularly relate to a kind of steel wire stay cable preventer and preparation side thereof
Method.
Background technology
Suspension cable is the peculiar component of cable-stayed bridge, and it plays is transmitted dead load and the mobile load of girder by Sarasota
To the effect of ground.Owing to suspension cable is generally disposed at outside beam body, and it is chronically under high-stress state,
Its sectional dimension is the least, therefore very sensitive to corrosiveness, even if occurring its intensity of slight corrosion also can
There is bigger loss.The most in process of production, steel wire stay cable typically uses hot-dip galvanizing technique to process,
Needing before treatment to first pass through pickling, phosphating process, Steel Wire Surface has the residue of acid, alkali liquor, stays
Descend the hidden danger of corrosion, made zinc coat easily produce and come off, and in hot dip galvanizing process, due to plating
Liquid temp is high, easily makes steel wire deform, and produces internal stress, affects its mechanical property.In use,
Steel wire stay cable also often as outsourcing hot extruded polyethylene sheath aging, cracking, and occur in various degree
Corrosion, had a strong impact on durability and the safety of cable-stayed bridge bridge span structure, it has to change the shape of rope
Formula ensures the normal use of bridge.And the manufacturing expense of suspension cable it is far longer than by the expense changing rope generation,
Also will have a strong impact on traffic, cause bad social influence simultaneously.
Summary of the invention
It is an object of the invention to overcome the shortcoming and defect of above-mentioned prior art, it is provided that a kind of technique is simple,
Cheap steel wire stay cable preventer and preparation method thereof, improves durability and the safety of suspension cable
Property.
The present invention is achieved through the following technical solutions:
A kind of steel wire stay cable preventer, including steel wire rope 1, the outer layer covers of described steel wire rope 1 has poly-
Fat band 3, the outer layer covers of described polyester band 3 has the pe sheath 4, described pe sheath 4 to be
Hollow structure 5, injects noble gas in this hollow structure 5.
Described steel wire rope 1 is made up of many steel wires, is filled with zinc powder 2 in the gap formed between every steel wire.
The cross sectional shape of described steel wire rope 1 is polygon.
The preparation method of above-mentioned steel wire stay cable preventer, comprises the steps:
(1), after steel wire rope 1 uses derusting by sandblasting, the zinc liquid after air cools down is sprayed directly into steel
On cord 1 surface, steel wire rope 1 surface is made to form protective layer；
(2) zinc powder 2 is filled between every steel wire of steel wire rope 1 in the gap formed；
(3) polyester band 3 is wrapped up in the periphery of steel wire rope 1；
(4) pe sheath 4 on the outer layer jacket of polyester band 3；
(5) finally inject inert gas in the hollow structure 5 of pe sheath 4, form noble gas
Layer.
The present invention, relative to prior art, has such advantages as and effect:
It is sprayed directly into steel wire rope 1 surface after being cooled down by air by zinc liquid, plays physics covering effect,
The corrosive mediums such as steel wire rope 1 and water and air are kept apart, owing to temperature during spraying is the lowest, steel
Cord 1 will not deform, and its interior mechanics performance is substantially unaffected.
Owing to the chemical property of zinc powder is relatively more active, electrode potential is lower than steel wire rope 1, corrodes at this
In battery, zinc powder is negative pole, and steel wire rope 1 is positive pole, and zinc powder loses electronics, becomes ion and enters electric Jie
Being corroded in matter solution, its free electron flows to steel wire rope 1, makes steel wire rope 1 polarize and be protected.
Polyester band 3 is wrapped in outside steel wire rope 1, in order to fix and to protect through overspray zinc and Zinc powder process
Steel wire rope 1 after process.
Owing to pe sheath 4 plays a part to completely cut off moisture and etchant gas to steel wire rope 1, also simultaneously
Can shielding of ultraviolet, prevent mechanical injuries.
Noble gas injects in the hollow structure 5 of pe sheath 4, forms layer of inert, thus enters
One step improves the decay resistance of steel wire rope 1.
Technical measure is simple and easy to do, safe and reliable, easy construction, substantially increases suspension cable
Durability and safety.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is more specifically described in detail.
Embodiment
As shown in Figure 1.One steel wire stay cable preventer of the present invention, including steel wire rope 1, described steel wire
The outer layer covers of rope 1 has polyester band 3, the outer layer covers of described polyester band 3 to have pe sheath 4,
Described pe sheath 4 is hollow structure 5, injects noble gas in this hollow structure 5.This hollow structure
For sealing hollow structure.
Described steel wire rope 1 is made up of many steel wires, is filled with zinc powder 2 in the gap formed between every steel wire.
The cross sectional shape of described steel wire rope 1 is polygon.
The preparation method of above-mentioned steel wire stay cable preventer, comprises the steps:
