Description
Technical field
The utility model relates to the suspension cable field that is used for bridge, is specially a kind of prefabricated parallel zinc-plated aluminum steel silk strand.
Background technology
Along with the continuous development and the technology innovation of suspension bridge and drag-line bridge technology, suspension bridge has worldwide obtained application more and more widely.The big portion of bridge floor weight of suspension bridge is born by the suspension cable strand, and therefore the quality to strand has very high requirement.Simultaneously, bridge span constantly increases at present, the length and the specification of corresponding main cable strand are also increasing, and have both at home and abroad much and building suspension bridge and building up the suspension bridge that needs to change main push-towing rope for many years, owing to be subjected to the restriction in anchoring space, also need to be replaced with the unit strand that specification is bigger, intensity of steel wire is higher.And main push-towing rope unit strand is toward big specification, and the high strength direction develops, and optimizing construction technology is arranged, alleviate bridge load, saves the effect of bridge cost.Therefore, the high strength and large specification of unit strand has become the inexorable trend of domestic and international large-span suspension bridge main push-towing rope technical development.But, the unit strand of present bridge, intensity and specification still can not be satisfied the demand, and can only reach 127 such as the specification maximum, can only reach requirement of strength with the method that increases unit strand quantity like this, thereby make complex process, cost increase.In addition, the suspension cable strand uses the high-tensile steel wires of plating zinc on surface more at present, though zinc-coated wire has certain antiseptic power, still is apparent not enough the service life more than 50 with respect to bridge, is still waiting to improve.
Summary of the invention
In order to overcome the defective of prior art, the bridge suspension cable of a kind of high strength, big specification is provided, the utility model discloses a kind of prefabricated parallel zinc-plated aluminum steel silk strand.
The utility model reaches goal of the invention by following technical solution:
