Description
Technical field
The utility model relates to a kind of steel strand wires, particularly a kind of 1 × 55 galvanized strand wires.
Background technology
Existing round stock galvanized strand wires is generally the structure of 1 × 3,1 × 7,1 × 19,1 × 37, and the arrangement sequence of its steel wire from inner ring to outer ring is 0+3,1+6,1+6+12,1+6+12+18 respectively, and its specification is not from φ 6.2mm ~ φ 28mm etc.Steel strand wires minimum breaking force is from 23.16KN ~ 660.07KN, and Nominal Tensile/MPa is from 1270MPa ~ 1670MPa, and their bulkfactor is respectively; 65.6%, 77.8%, 76.03%, 75.5%.
But, because existing steel strand wires steel wire arranging is unreasonable, make to be point-like contacts between its steel wire and steel wire, the steel strand wires of this point-like contacts are when being subject to pulling force and the pressure of vertical and horizontal, every layer of steel wire and adjacent layer steel wire are formed shears shape scar, it is great for shearing the harm of shape scar to steel strand wires, can hurt the zinc-iron alloy layer of zinc-coated wire.
In addition, it is comparatively large that point-like contacts causes steel strand wires internal voids, and its bulkfactor is about 75% to the maximum, and its pulling force of same specification steel strand wires is restricted, and when not adding large gauge, can only meet the demand of user by increasing every square millimeter, steel wire MPa.But the maximum outside diameter of the Fine Steel Casting iron wire rod produced by each steel mill at present is also difficult to meet consumers' demand.If rely on the geometry external diameter strengthening steel wire to strengthen the pulling force of steel strand wires, once external diameter is infinitely-great time, its transport is again difficult.
Further, steel strand wires space is comparatively large, is in use very easily subject to the infringement of harmful substance, can causes these steel strand wires except being corroded from outside, also can be corroded from inside simultaneously, thus the service life of conventional steel twisted wire is on the hazard.
Summary of the invention
The purpose of this utility model is to provide that a kind of scientific structure design is reasonable, tensile strength large, long service life, be convenient to 1 × 55 galvanized strand wires that transports.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of 1 × 55 galvanized strand wires, it is characterized in that: formed by five layers of steel wire twisting, first steel wire floor is made up of 1 steel wire, second steel wire floor and the 3rd steel wire floor are formed by 9 steel wires, 4th steel wire floor and the 5th steel wire floor are formed by 18 steel wires, the external diameter of the first steel wire floor steel wire is 5.67mm, the external diameter of the second steel wire floor each steel wire is 2.95mm, the external diameter of the 3rd steel wire floor each steel wire is 5.4mm, 4th steel wire floor steel wire is arranged by the steel wire interval of external diameter to be the steel wire of 4.74mm and external diameter be 3.6mm and forms, the external diameter of the 5th steel wire floor each steel wire is 5.44mm.
And common twisting in the same way after the first described steel wire floor, the second steel wire floor, the 3rd steel wire floor and the 4th steel wire floor arrangement bunchy, the 5th described steel wire floor reverse lay is formed on the outside of the 4th steel wire floor.
Advantage of the present utility model and beneficial effect are:
1. 1 × 55 galvanized strand wires, by when keeping product outside dimension constant, increase the radical of steel wire, its pliability and endurance are strengthened, its minimum breaking force can reach 1.228KN, exceeds 1.86 times of YB/T5004-2012 standard maximum pull 660.07KN; By the setting of various outer diameter steel wire, increase the bulkfactor of steel strand wires, its bulkfactor exceeds about 6% than YB/T5004-2012 standard.This strand structure reaches optimization, and tensile property is more rational, because cover wire and adjacent layer steel wire are twisted with the fingers to contrary, can reach micro-rotation during use.
2. the utility model design science is reasonable, and having that tensile strength is large, long service life, be convenient to the advantage of transporting, is a kind of 1 × 55 galvanized strand wires with higher innovation.

1-the 5th steel wire floor, 2-the 4th steel wire floor, 3-the 3rd steel wire floor, 4-first steel wire floor, 5-second steel wire floor.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of 1 × 55 galvanized strand wires, its innovation is: formed by five layers of steel wire twisting, first steel wire floor 4 is made up of 1 steel wire, second steel wire floor 5 and the 3rd steel wire floor 3 are formed by 9 steel wires, 4th steel wire floor 2 and the 5th steel wire floor 1 are formed by 18 steel wires, the external diameter of the first steel wire floor steel wire is 5.67mm, the external diameter of the second steel wire floor each steel wire is 2.95mm, the external diameter of the 3rd steel wire floor each steel wire is 5.4mm, 4th steel wire floor steel wire is arranged by the steel wire interval of external diameter to be the steel wire of 4.74mm and external diameter be 3.6mm and forms, the external diameter of the 5th steel wire floor each steel wire is 5.44mm.
Common twisting in the same way after the first described steel wire floor, the second steel wire floor, the 3rd steel wire floor and the 4th steel wire floor arrangement bunchy, the 5th described steel wire floor reverse lay is formed on the outside of the 4th steel wire floor.
This steel wire is when producing, and carry out twisting at twice, the first steel wire floor first carry out twist-on-twist system to the 4th steel wire floor, and then carries out reverse twisting with the 5th steel wire floor, can reach micro-rotation during use, is applicable to electric pole, the traction of steel tower, pulling.
This 1 × 55 galvanized strand wires, by when keeping product outside dimension constant, increase the radical of steel wire, its pliability and endurance are strengthened, its minimum breaking force can reach 1.228KN, exceeds 1.86 times of YB/T5004-2012 standard maximum pull 660.07KN; By the setting of various outer diameter steel wire, increase the bulkfactor of steel strand wires, its bulkfactor exceeds about 6% than YB/T5004-2012 standard.This strand structure reaches optimization, and tensile property is more rational, because cover wire and adjacent layer steel wire are twisted with the fingers to contrary, can reach micro-rotation during use.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
