Abstract
The utility model relates to a steel rope with the resistance of ultrahigh fatigue stress amplitude, which is mainly used in bridges and other construction structures. The steel rope is characterized in that a steel tendon (1) is composed of steel wires with the fatigue stress amplitude reaching to above 500 MPa, and the steel tendon (1) is stranded by 2 degrees plus/minus 0.5 degrees; a fiber band is wound on the surface of the steel tendon (1); anchor devices (5) are mounted at two ends of the steel tendon (1); anti-fatigue rings (2) are mounted at the transitional parts between the anchor devices and the steel tendon (1); and copper zinc alloy (3) and an epoxy filler (4) are filled between the anchor devices (5) and the steel tendon (1). The steel rope provided by the utility model has ultrahigh stress amplitude and anti-fatigue performance, that is, the stress toplimit of the steel rope is 0.4 times more than nominal breaking load, the ultrahigh stress amplitude achieves 400 MPa above, and the cycle index for anti-fatigue performance achieves 2 million.
Description
Technical field
The utility model relates to a kind of cable wire.Be mainly used in bridge and other building structure.Belong to the building structural member technical field.
Background technology
The anti-fatigue performance of cable wire has directly determined its cycle fatigue life.Traditional cable wire is applied to mobile load and accounts for bridge and other building structure than small scale.The stress amplitude of its cable wire requires generally between 100-200MPa.The large-span cable net that is used for along with difference and the appearance of rope membrane structure, its mobile load that acts on the cable wire has accounted for bigger ratio, requires the stress upper limit of cable wire to reach 0.4 times the disrumpent feelings load of nominal, has
400MPa withOn the ultrahigh stress width of cloth, cycle-index reach 2,000,000 times anti-fatigue performance.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of cable wire with anti-superelevation Fatigue Stress Amplitude of the ultrahigh stress width of cloth and anti-fatigue performance is provided.
The purpose of this utility model is achieved in that a kind of cable wire of anti-superelevation Fatigue Stress Amplitude, and this cable wire is that the steel wire that Fatigue Stress Amplitude reaches more than the 500MPa is formed steel tendon, the steel tendon process
2 ° ± 0.5 °Twisting is wound with fabric strip on the steel tendon surface, at the steel tendon two ends ground tackle is installed, and the intermediate location of ground tackle and steel tendon is equipped with the antifatigue ring, is filled with pltine and epoxy filler between ground tackle and the steel tendon.
The beneficial effects of the utility model are:
The utility model cable wire is that the steel wire that Fatigue Stress Amplitude reaches more than the 500MPa is formed steel tendon, and steel tendon makes cable wire have the ultrahigh stress width of cloth and anti-fatigue performance through 2 ° ± 0.5 ° twisting, and the stress upper limit of cable wire reaches
0.4 doublyThe disrumpent feelings load of nominal, have
More than the 400MPaThe ultrahigh stress width of cloth, cycle-index reach 2,000,000 times anti-fatigue performance.
