A kind of main rope of suspension bridge of the utility model, described main push-towing rope includes the hexagon cable consisting of multiply strand, on above-mentioned strand, be coated with zinc aluminum alloy coating, and the end of cable is connected with anchor cup, the above-mentioned strand that stretches into the cable that is fixed connection in anchor cup is only coated with zinc aluminum alloy coating, on the zinc aluminum alloy coating of the above-mentioned strand that is positioned at the formation cable outside anchor cup, be coated with epoxy resin coating, and be filled with pltine in anchor cup.
A kind of main rope of suspension bridge of the utility model, is provided with locating ring and connecting cylinder between described anchor cup and cable, and is filled with anti-corrosion material between connecting cylinder and cable.
A kind of main rope of suspension bridge of the utility model, has tied up the band that is wrapped on above-mentioned cable.
A kind of main rope of suspension bridge of the utility model, is provided with locating ring between described anchor cup and cable, and is filled with anti-corrosion material between locating ring and cable.
A kind of main rope of suspension bridge of the utility model, and on above-mentioned cable, tied up the band that is wrapped.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is by applying successively zinc aluminum alloy coating and epoxy resin coating outward at steel wire, reach the effect that improves intensity and resistance to corrosion, and strand is positioned at the part of anchor cup in order better to fuse with the pltine that is filled in anchor cup, this part strand only applies allumen, thereby improve it in conjunction with effect, improve the anti-pull ability of main push-towing rope; By above-mentioned improvement, greatly improved intensity and the resistance to corrosion of strand, be conducive to it and improve application life.
