Description
Technical field
This utility model relates to a kind of wire rod, and particularly a kind of highway barrier galvanized steel wire rope, belongs to highway barrier equipment technical field.
Background technology
Highway barrier is the traffic protection construction of road, is generally adopted steel board and makes, and adopts zinc-plated steel cable to substitute steel board also being promoted and applying progressively.The advantages such as zinc-plated steel cable has materials province, strong adaptability compared to steel board, maintenance reparation is convenient, security performance is good.But also the mechanical performance of steel wire rope is had higher requirement.
Summary of the invention
Goal of the invention of the present utility model is in that: for above-mentioned Problems existing, it is provided that a kind of rational in infrastructure, highway barrier galvanized steel wire rope that favorable working performance, long service life, tensile strength are high.
The technical solution adopted in the utility model is as follows:
Highway barrier galvanized steel wire rope, rope body is formed by 3 bursts of steel wire twistings, by 1 core wire and twisting, 6 outer rim steel wires in core wire periphery form per share steel wire, the diameter of core wire is 2.72mm-3.0mm, outer rim gauge of wire is 2.6mm-2.8mm, and the outer wall of core wire and outer rim steel wire all has zinc coat.
Further, the diameter of described core wire is more than outer rim gauge of wire.
Further, the diameter of described core wire 0.1mm-0.20mm bigger than outer rim gauge of wire.
Further, the lay pitch of described rope body is 156mm-171mm.
Further, the material of described core wire and outer rim steel wire is No. 70 steel.
Further, the diameter of described rope body is 16mm-18mm.
Further, the thickness of described zinc coat is not less than 230g/m2。
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
Described highway barrier galvanized steel wire rope, rational in infrastructure, favorable working performance, long service life, individual wire tensile strength reach more than 1570MPa, and minimum total Fracture Force can reach 147KN-198KN.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Labelling in figure: 1-steel wire, 2-core wire, 3-outer rim steel wire.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Embodiment
Highway barrier galvanized steel wire rope, its structure is as shown in Figure 1, rope body is formed by 3 bursts of steel wire 1 twistings, by 1 core wire 2 and twisting, 6 outer rim steel wires 3 in core wire 2 periphery form per share steel wire 1, the diameter of core wire 2 is 2.72mm-3.0mm, the diameter of outer rim steel wire 3 is 2.6mm-2.8mm, and the outer wall of core wire 2 and outer rim steel wire 3 all has zinc coat.In the present embodiment, core wire 2 and outer rim steel wire 3 adopt No. 70 steel to draw and form.
In another embodiment, the diameter of described core wire 2 is more than the diameter of outer rim steel wire 3.Preferably, the diameter of described core wire 0.1mm-0.20mm bigger than outer rim gauge of wire so that outer rim steel wire 3 and core wire 2 reach good twisted effect, it is ensured that twisted reliable, also makes three bursts of steel wire 1 twisted better effects if.The diameter of core wire 2 and outer rim steel wire 3 combines in being embodied as and can be such that core wire diameter 2.72mm, outer rim steel wire diameter are 2.62mm；Core wire diameter 2.75mm, outer rim steel wire diameter are 2.6mm；Core wire diameter 3.0mm, outer rim steel wire diameter are 2.8mm.
In the present embodiment, the lay pitch of described rope body is 156mm-171mm so that whole-root rope body tight, intensity is more preferably.The diameter of described rope body is 16mm-18mm.
In order to ensure weatherability and the life-span of steel cable, in the present embodiment, the thickness of the zinc coat 4 of core wire 2 and outer rim steel wire 3 is not less than 230g/m2。
Highway barrier galvanized steel wire rope of the present utility model, rational in infrastructure, favorable working performance, long service life, anticollision ability are better than former steel guardrail, improve traffic safety, the tensile strength of individual wire reaches more than 1570MPa, minimum total Fracture Force can reach 147KN-198KN, compared to minimum total Fracture Force requirement of the 135KN-170KN of national standard, promote nearly 14%-16%, there is good effect.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
