Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of resistance to corrosion by force and main rope of suspension bridge and this main push-towing rope strand of long service life.
The object of the present invention is achieved like this: a kind of main rope of suspension bridge strand, described main rope of suspension bridge includes steel wire with strand, on described steel wire, is coated with zinc aluminum alloy coating, is coated with epoxy resin coating on described zinc aluminum alloy coating.
A kind of main rope of suspension bridge of the present invention, described main push-towing rope includes the hexagon cable being made up 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 present invention, 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 present invention, has tied up the band that is wrapped on above-mentioned cable.
A kind of main rope of suspension bridge of the present invention, 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 present invention, and on above-mentioned cable, tied up the band that is wrapped.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention 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 improve intensity and the resistance to corrosion of strand, be conducive to it and improve application life.
