The plastic-coated layer is hot-pressed and pasted on the outer surface of the inner core, so that the concrete-coated composite material has the characteristics of corrosion resistance, acid and alkali resistance, static resistance, aging resistance, good toughness, high tensile strength and the like, simultaneously, the gluing in-row process is omitted, all single materials are in bulk, the stirring and dispersing effect in the thrown concrete is good, the dispersion is more uniform, and the conglomeration phenomenon cannot occur; and the outer surface of the plastic-coated steel fiber inner core is threaded, and the two ends of the plastic-coated steel fiber inner core are provided with hooks, so that the plastic-coated layer on the outer surface of the inner core is not easy to fall off in the concrete stirring process or when the concrete is impacted by external force or pulled.
Description
Technical Field
The utility model relates to a steel fiber structure technical field, more specifically the cover and mould steel fibre that says so relates to one kind.
Background
The steel fiber is a fiber with a length-diameter ratio of 40-80 prepared by a thin steel wire cutting method, cold-rolled strip steel shearing, steel ingot milling or molten steel rapid condensation method. The properties of the steel fibers produced by different preparation methods are different. Although steel fibers are coming out soon, the application is more and more extensive and the variety is more and more.
However, the existing steel fiber has poor performance, and the outer surface is easily damaged; and meanwhile, when the composite material is put into concrete, the conglomeration phenomenon is easy to occur, the daily use requirement cannot be met, and even if the plastic-coated steel fiber is adopted, the plastic-coated material on the surface of the steel fiber is easy to fall off when being impacted.
Therefore, the problem to be solved by those skilled in the art is to provide a plastic-coated steel fiber with excellent and stable performance.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a cover and mould steel fibre, the superior stable performance, it is effectual to stir the dispersion in putting in the concrete simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a plastic-coated steel fiber, which comprises an inner core and a plastic-coated layer,
the outer surface of the inner core is in a thread shape, and two ends of the inner core are in hook-shaped structures;
the plastic coating layer is hot-pressed and attached to the outer surface of the inner core.
Further, the inner core has a straight section, and the ratio of the length of the straight section to the length of the hook structure is 4: 1.
Furthermore, the inner core is made of a steel wire material with the diameter of more than or equal to 0.4mm and the tensile strength of more than or equal to 700 MPa.
Further, the cross section of the inner core is round or flat.
Furthermore, the plastic-coated layer is made of PVA or PP materials.
Furthermore, the thickness of the plastic-coated layer is more than or equal to 0.1 mm.
Through taking above scheme, the beneficial effects of the utility model are that:
1) the plastic-coated layer is hot-pressed and pasted on the outer surface of the inner core, so that the concrete composite material has the characteristics of corrosion resistance, acid and alkali resistance, static resistance, aging resistance, good toughness, high tensile strength and the like, and the plastic-coated layer is hot-pressed and pasted on the outer surface of the inner core, so that a gluing and row-arranging process is omitted, all single materials are in bulk, the stirring and dispersing effect in the thrown concrete is good, the dispersion is more uniform, and the agglomeration phenomenon cannot occur;
2) the outer surface of the plastic-coated steel fiber inner core is threaded, and the two ends of the plastic-coated steel fiber inner core are provided with hooks, so that the plastic-coated layer on the outer surface of the inner core is not easy to fall off in the concrete stirring process or when the concrete is impacted by external force or pulled.
