Abstract
The utility model discloses a prestress wire is restrainted, including hollow steel pipe, copper strands and steel strand wires, the inside packing of hollow steel pipe has the carbon body, the outside transposition of hollow steel pipe has aluminium conductors (cable) steel -reinforced, the copper strands transposition is in aluminium conductors (cable) steel -reinforced's gap department, the gap department with copper strands at copper strands is woven to steel strand wires, steel strand wires have zinc -plated copper strands with the gap department transposition of steel strand wires. The utility model discloses steel strand wires are restrainted, and copper strands, tin -coated copper hank and the steel strand wires in the outside adopt seamless connection for steel strand wires are restrainted has stronger cohesiveness, and is difficult to produce and slides, and the protruding rib that is equipped with of the angles such as surface of steel strand wires has simultaneously increased steel strand wires and copper strands's etc. Bond stress, therefore, the utility model relates to a rationally, simple structure not only can reduce cost, alleviates the weight that these steel strand wires were restrainted, can improve the prestressing force that steel strand wires were restrainted moreover greatly.
Description
Technical field
The utility model belongs to steel strand wires technical field, is specifically related to a kind of prestressing tendon.
Background technology
Existing prestressing tendon is all made up of central hair and Bian Si, shortcoming is the cross section of central hair and Bian Si is all circular, hole between them is large, contact area between steel wire is less, the frictional force that effective contact produces is little, very easily produce core silk edge slippage retraction, core silk stress is caused to reduce or lose stress completely, constrain quality and the life-span of prestress wire, simultaneously, the steel wire bundle formed is all light face, make concrete and steel wire bundle to agree with effect bad, affect steel strand wires and concrete bond stress, reduce quality and the service life of concrete strand structure.Meanwhile, existing prestressing tendon is all adopt that the steel wire of material of the same race is stranded to be formed, and not only weight is large, and increases cost.
Utility model content
The purpose of this utility model is to provide a kind of prestressing tendon, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of prestressing tendon, comprise hollow steel pipe, copper stranded conductor and steel strand wires, the inside of described hollow steel pipe is filled with carbon body, the outside of described hollow steel pipe is stranded steel-cored aluminium strand, described copper stranded conductor is stranded in the gap place of steel-cored aluminium strand, and described steel strands-woven is woven in the gap place of copper stranded conductor and copper stranded conductor, and the gap place of described steel strand wires and steel strand wires is stranded tin-coated copper twisted wire.
Preferably, described steel strand surface is angularly at least provided with six groups of salient ribs, described salient rib move towards undulate or fold-line-shaped.
Preferably, described steel-cored aluminium strand comprises aluminum steel and steel wire, and aluminum steel is woven in the outside of steel wire.
Technique effect of the present utility model and advantage: this prestressing tendon, can not only be increased the prestressing force of steel wire bundle, and can reduce the steel wire consumption of steel wire bundle, reduce costs by the carbon body of filling in hollow steel pipe inside; Its steel-cored aluminium strand can alleviate the weight of this steel wire bundle and improve the corrosivity of this steel wire bundle; The outermost copper stranded conductor of this steel wire bundle, tin-coated copper strand and steel strand wires adopt seamless link, steel wire bundle is made to have stronger cohesiveness, and be not easy to produce and slide, simultaneously the salient rib that is angularly provided with of the surface of steel strand wires, adds the bond stress of steel strand wires and copper stranded conductor etc.; Therefore, the utility model is reasonable in design, and structure is simple, can not only reduce costs, alleviate the weight of this steel wire bundle, and greatly can improve the prestressing force of steel wire bundle.
Accompanying drawing explanation
