Abstract
The utility model relates to a windproof and rainproof and shockproof standing rope, including an anchor and a rope body. A sheath of the rope body is internally provided with a steel wire bundle and has the external surface provided with a dual-spiral wire flange. Through the arrangement of the dual-spiral wire flange on the sheath surface, the utility model can prevent the formation of water ways on the standing rope surface and stabilize the pneumatic force on the standing rope surface, thereby avoiding the wind-rain induced vibration, achieving good result in vibration reduction and being helpful for the service life prolonging of the cable stayed bridge, in particular to the long-span cable stayed bridge.
Description
Technical field
The utility model relates to a kind of drag-line that is used for bridge engineering.
Technical background
At present, drag-line generally all is to adopt half parallel galvanized steel rope to extrude light face pe sheath outward to protect.There are 2 shortcomings in actual use in this drag-line: the one, rain when blowing, drag-line can be subjected to the effect of wind and rain vibration, and deflection repeatedly takes place root, makes the steel wire in the rope produce additional flexural stress, thereby quicken the fatigue of steel wire, reduce the application life of drag-line.This shows particularly outstandingly on large span stayed-cable bridge, high wind speed area cable stayed bridge, estuary place cable stayed bridge.The 2nd, waterproof measure is not taked in the steel wire gap in the drag-line, in case the lasso protection damage layer, rainwater will enter in the steel wire gap, corrosion steel wire, the application life of minimizing drag-line.In order to slow down inhaul cable vibration, existing drag-line has all been installed damping shock absorber or oil-pressure damper at its two ends.The minority suspension cable also is provided with pit in the pe sheath appearance.
Summary of the invention
The purpose of this utility model provides a kind of drag-line of anti-wind, rain and vibration.The further purpose of the utility model is to make the antiseptic property of drag-line better.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-wind, rain and vibration drag-line, comprise anchor head and cable body, and in the sheath of cable body steel tendon is housed, jacket outer surface is provided with the bifilar helix flange.
Described sheath is divided into skin and internal layer, and skin and flange can be made into colour, so that coordinate mutually with view around the bridge, is provided with the band that is wrapped between sheath internal layer and the steel tendon, is used for the steel tendon typing that is wrapped.The cross sectional shape of flange is semicircle or half elliptic.The helical angle of bifilar helix flange is 70～75 °, and flange width is 4.5 ± 0.5mm, highly is 3 ± 0.5mm.
In order to increase the antiseptic property of drag-line, in the steel wire gap of steel tendon, be marked with anticorrosion grease.
The utility model is by being provided with the bifilar helix flange at jacket surface, can stop the formation in water route, drag-line surface, stablize the aerodynamic force on drag-line surface, thus the generation of having avoided wind and rain to shake, good damping result helps prolonging cable stayed bridge life-span of large span stayed-cable bridge drag-line especially.The utility model is by injecting anticorrosion oil layer in the steel wire gap, perfect lasso protection system can prevent the erosion of sheath damage back rainwater effectively, and antiseptic effect is obvious.
Description of drawings
Fig. 1 is a section structure schematic diagram of the present utility model;
General structure schematic diagram when Fig. 2 is left-handed for the utility model bifilar helix flange;
General structure schematic diagram when Fig. 3 is dextrorotation for the utility model bifilar helix flange.
The specific embodiment
As shown in Figure 1, drag-line comprises anchor head 7 and cable body 8 two parts.The pe sheath of cable body 8 is double-deck, is respectively internal layer 4 and outer 5.In outer 5 Surface Machining of sheath bifilar helix flange 6 is arranged, sheath and bifilar helix flange are a coextrusion mold, and its manufacturing cost is compared with light face double layer rubber sleeve drag-line to be increased seldom.The cross sectional shape of flange 6 is semicircle, half elliptic or other shape that is fit to, and bifilar helix flange 6 can be left-handed as shown in Figure 2, also dextrorotation as shown in Figure 3.The helical angle of bifilar helix flange 6 is 70～75 °, and flange width A is 4.5 ± 0.5mm, and height B is 3 ± 0.5mm.Sheath outer 5 and bifilar helix flange 6 can be made into colour, so that coordinate mutually with the view around the bridge.Between steel tendon 1 and sheath internal layer 4, be provided with being wrapped of making of polyester composite band and be with 2, be used for the steel tendon typing that is wrapped.In the steel wire gap of steel tendon 1, be marked with anticorrosion oil layer 3, can effectively prevent the erosion of cable body sheath damage back rainwater, have good antiseptic effect.
Claims (5)
