Abstract

The utility model discloses a steel wire inhaul cable for a large-span building. The steel wire inhaul cable comprises a steel wire bundle, wherein a plastic sleeve is arranged on the steel wire bundle, a zinc layer is arranged between the plastic sleeve and the surface of the steel wire bundle, an anticorrosive layer is coated on the zinc layer, and a fireproof material is arranged in the plastic sleeve. The steel wire inhaul cable has the advantages that one anticorrosive layer is additionally added on the zinc layer, in addition, the fireproof material is arranged in the plastic sleeve and is perlite, the problems of poor fireproof performance and poor anticorrosive effect in the prior art are solved, the use value of the steel wire inhaul cable is improved, and the service life of a bridge is also prolonged.

Description

A kind of wire digging line that is used for long span building
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 fire line is poor, makes that the wire digging line life-span 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 that is used for long span building.The utility model is set up one deck anticorrosive coat through being employed on the zinc layer; And be provided with fire proofing material in the plastic sheath, fire proofing material is a perlite, has overcome the bad problem with the fire line difference of prior art anticorrosion ability; Improve the use value of wire digging line, also prolonged the application life of bridge.
The utility model adopts following technical scheme to realize:
A kind of wire digging line that is used for long span building 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, scribbles anticorrosive coat on the said zinc layer, it is characterized in that: be provided with fire proofing material in the said plastic sheath.
Said fire proofing material is a perlite.
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; And be provided with fire proofing material in the plastic sheath, fire proofing material is a perlite, has overcome the bad problem with the fire line difference of prior art anticorrosion ability; Improve the use value of wire digging line, also prolonged the application life of bridge.
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.
