Abstract
The utility model discloses a steel-wire stay cable, comprising a steel wire bundle, wherein the steel wire bundle is provided with a plastic sleeve and a zinc layer is arranged between the surface of the steel wire bundle and the plastic sleeve; and an anti-corrosion layer is coated on the zinc layer. According to the utility model, one layer of the anti-corrosion layer is additionally arranged on the zinc layer, so that the defect that the anti-corrosion effect of the prior art is not good is overcome, the use value of the steel-wire stay cable is improved and the service life of a bridge is prolonged.
Description
Technical field
The utility model relates to a kind of wire digging line, particularly relates to a kind of wire digging line of using under long span building or the analogue of being used for.
Background technology
Wire digging line is one of key stressed member of cable stayed bridge, so wire digging line has also determined the life-span length of bridge.Present wire digging line is because antiseptic effect is bad, too early damages because of rust corrosion.
For example application number is 90211306.2; Publication number is 2068534 Chinese patent " a kind of Brick with tongue and groove "; A kind of wire digging line of multilayer proofing is disclosed; Plastic sheath (4) is arranged on the steel tendon (1), it is characterized in that: between steel tendon (1) surface and the plastic sheath (4) metallic zinc layer (2) is arranged, be sprayed with layer of aluminum, copper or chromium metal level (3) on the zinc layer (2).But the brick anticorrosion ability of this utility model still has problems, and the wire digging line life-span is short.
The utility model content
The purpose of the utility model is to overcome the problems referred to above that wire digging line exists in the prior art, proposes a kind of wire digging line.The utility model is set up one deck anticorrosive coat through being employed on the zinc layer, overcome the bad problem of prior art anticorrosion ability, has improved the use value of wire digging line, has also prolonged the application life of bridge.
The utility model adopts following technical scheme to realize:
A kind of wire digging line comprises steel tendon, and said steel tendon is provided with plastic sheath, is provided with the zinc layer between the surface of said steel tendon and the plastic sheath, it is characterized in that: scribble anticorrosive coat on the said zinc layer.
The thickness of said zinc layer is 1.1-2mm.
Said anticorrosive coat is an epoxy resin layer.
The utility model compared with prior art, its advantage is:
1, the utility model is employed in and sets up one deck anticorrosive coat on the zinc layer, has overcome the bad problem of prior art anticorrosion ability, has improved the use value of wire digging line, has also prolonged the application life of bridge.2, the utility model adopts the positive truncated rectangular pyramids that is shaped as of boss, and is simple in structure, easy to use.
2, the thickness of the utility model employing zinc layer is 1.1-2mm, can select thickness according to the different dynamics that receives, and is easy to use.
3, the utility model employing anticorrosive coat is an epoxy resin layer, and the epoxy resin layer anticorrosive property is strong, and effect is remarkable.
