Description
Technical field
The utility model is related to bridge cable structure of steel wire, specially a kind of bridge cable hot dip zinc-copper-titanium alloy steel
The structure of silk.
Background technology
Suspension bridge and cable-stayed bridge can reduce moment of flexure in beam body as guy system, reduce building height, mitigate structure weight
Amount, saves material, and the span ability than beam bridge is bigger, is the main bridge type of current Large Span Bridges in the world.With economy
Fast development, the continuous construction of crossing-fiver bridge over strait, the service life requirement for bridge cable further improves.In addition,
For suspension bridge and cable-stayed bridge, the cost of cable accounts for the 25~30% of bridge total cost, and cable is used as the master of bridge
Primary structure member is wanted to be referred to as " lifeline " of bridge.Therefore, bridge cable is bridge operation safety with the decay resistance of steel wire
With the key factor of service life.
At present, bridge cable generally uses the pure zinc coating of hot dip with steel wire, with the raising of Bridge Design service life, heat
Zinc-aluminium-alloy steel wire（Aluminium content：4.2%~7.2%）Start to apply in some large and medium-sized projects at home, in equal coating
Thickness（It is not less than 300g/m2）Under conditions of, the decay resistance of Zn-Al Alloy Coated Steel Wire is 2~3 times of zinc-coated wire.
Zinc-copper-titanium alloy be the forties in last century develop a kind of high intensity, highly corrosion resistant, creep resistant alloy, its machinery
Performance can compare favourably with copper alloy, aluminium alloy.Progressively industrial production and application, the structure opened up are obtained after the sixties in America and Europe
The frontier of material.The alloy has obtained substantial amounts of application in fields such as building, machinery, transport, instrument and meters, and it should
Constantly expanded with field.Such as apply on the roof boarding of large stadium or industrial premises, relative to common color steel, zinc
Copper-titanium alloy plate can reduce roofing weight about 10%, and corrosion resistance and service life are far above color steel.Zinc-copper-titanium alloy is in bridge
Application on cable steel wire, can effectively improve the decay resistance of steel wire and the creep-resistant property of coating and mechanical performance.
Therefore, application of the technology in the protection of bridge cable steel wire, can solve the problem that the problems in engineering, and can bring can
The economic benefit of sight.
Utility model content
The purpose of this utility model is to provide a kind of bridge cable hot dip zinc-copper-titanium alloy on the basis of existing technology
Steel wire, the structure of steel wire is simple, and protective coating is well combined with steel wire matrix, and thickness is uniform, organizes fine and closely woven, intensity is high.
The technical scheme in the invention for solving the above technical problem is：A kind of bridge cable hot dip zinc-copper-titanium alloy
Steel wire, including steel wire matrix, the uniform zinc-copper-titanium alloy coating of steel wire matrix surface cladding thickness, zinc-copper-titanium alloy coating
For double-layer structure, internal layer is the alloy transition layer that corrosion resistance is strong, hardness is high, and outer layer is outside the alloy that plasticity is preferable, surface is smooth
Coating.
Preferably, the zinc-copper-titanium alloy thickness of coating quality is not less than 300g/m2。
Preferably setting is, the steel wire matrix uses the high tensile steel wire of middle and high carbon component.
Compared with prior art, the utility model has the advantage of：
（1）Its anticorrosive coat thickness is uniform, organize fine and closely woven, is well combined with matrix, and intensity is high, creep-resistant property is good.Hot dip
Zinc-copper-titanium alloy Steel Wire Surface is smooth, and favorable anti-corrosion effect, service life is long.
（2）Because the intensity of zinc-copper-titanium alloy is high, creep-resistant property is more preferable, application can be prevented on main rope of suspension bridge strand
To the damage of coating in work progress, and it can prevent cord clip from causing sliding due to coating creep.
Brief description of the drawings

Fig. 2 is the radial cross-section of hot dip zinc-copper titanium steel silk in the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, the bridge cable hot dip zinc-copper-titanium alloy steel wire in the present embodiment, the surface of steel wire matrix 3 is covered
Cover zinc-copper-titanium alloy coating in uniform thickness.Zinc-copper-titanium alloy coating is double-layer structure, and internal layer is the conjunction that corrosion resistance is strong, hardness is high
Golden transition zone 2, outer layer is the alloy serving 1 that plasticity is preferable, surface is smooth.The zinc-copper-titanium alloy thickness of coating quality is not
Less than 300g/m2, the high tensile steel wire of the middle and high carbon component of the use of matrix 3 of hot dip zinc-copper-titanium alloy steel wire.
Cu content is that 1%~2%, Ti content is 0.1%~0.5% in coating, and remaining is Zn.
In addition to the implementation, the utility model also includes other embodiment, all use equivalents or equivalent
The technical scheme of substitute mode formation, all should fall within the utility model scope of the claims.
