Abstract
The utility model relates to an epoxy coating steel wire stay cable, which is provided with a steel wire cable body (1), a black high-density polyethylene layer (2) and a color high-density polyethylene (3) through the compact compounding from inside to outside, and is characterized in that the surface of each steel wire in the steel wire cable body (1) is coated with an epoxy resin coating, thereby forming an epoxy resin coating steel wire stay cable. The epoxy resin coating steel wire stay cable has tensile strength larger than 1860MPa and higher corrosion resistance life.
Description
(1) technical field
The utility model relates to a kind of suspension cable that is used for cable stayed bridge.Belong to bridge construction part technical field.
(2) background technology
Suspension cable is the main bearing member of cable stayed bridge, and it is arranged in the beam external body, and is under the high-stress state for a long time, and sectional dimension is again little, thus very responsive to corrosiveness, so the suspension cable corrosion is the very serious problem that people face always.Along with a large amount of constructions of large span stayed-cable bridge, the anticorrosion life-span and the tensile strength of its suspension cable are had higher requirement at present.
Before the utility model is made, the suspension cable cross section structure that in the past was used for cable stayed bridge as shown in Figure 1: this suspension cable closely is composited by steel wire cable body, black high-density polyethylene layer and color high-density polyethylene sheath from the inside to the outside successively.Can not satisfy higher anticorrosion life requirements of suspension cable and tensile strength requirement.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the epoxy coating steel wire stay cable that a kind of anticorrosion life-span is long, tensile strength is high is provided.
The purpose of this utility model is achieved in that a kind of epoxy coating steel wire stay cable, described suspension cable closely is composited by steel wire cable body, black high-density polyethylene layer and color high-density polyethylene sheath from the inside to the outside successively, it is characterized in that: every Steel Wire Surface of described steel wire cable body is coated with epoxy coating, constitute the epoxy coating steel wire stay cable, the tensile strength of this epoxy coating steel wire stay cable is greater than 1860MPa, and the anticorrosion life-span is higher.
Epoxy resin is as organic nonmetallic coating; its not with reactions such as acid, alkali; have that high chemical stability and ductility are big, drying shrinkage is little; and has splendid stickiness with the metal surface; can form its physical barriers that contacts with moisture, oxygen, chloride or corrosive medium of obstruct in the metal surface; simultaneously, also have the function that barrier metal contacts with extraneous electric current, can protect metal material to exempt from corrosion effectively.The epoxy coating coating generally about 230 ℃, can not cause the decline of steel wire intensity such as 450 ℃ of galvanizings the time in addition.Therefore the epoxy coating steel wire not only has excellent antiseptic property, and has the higher tensile strength greater than 1860MPa, can satisfy the demand that current suspension cable develops to high strength, durability direction day by day.
The anticorrosion life-span of the utility model epoxy coating steel wire stay cable is long, the tensile strength height.
(4) description of drawings
Fig. 1 is a suspension cable cross section structure schematic diagram in the past.
Fig. 2 is the utility model epoxy coating steel wire stay cable cross section structure schematic diagram.
Reference numeral among the figure: steel wire cable body 1, black high-density polyethylene layer 2, color high-density polyethylene sheath 3, zinc-coated wire 4.
(5) specific embodiment
Referring to Fig. 2, the epoxy coating steel wire stay cable that the utility model relates to closely is composited by steel wire cable body 1, black high-density polyethylene layer 2 and color high-density polyethylene sheath 3 from the inside to the outside successively.Every Steel Wire Surface of described steel wire cable body 1 is coated with epoxy coating, constitutes the epoxy coating steel wire, and the tensile strength of this epoxy coating steel wire is greater than 1860MPa.
Claims (1)
1, a kind of epoxy coating steel wire stay cable, described suspension cable closely is composited by steel wire cable body (1), black high-density polyethylene layer (2) and color high-density polyethylene sheath (3) from the inside to the outside successively, it is characterized in that: every Steel Wire Surface of described steel wire cable body (1) is coated with epoxy coating.
