Abstract
The utility model provides a kind of and anticorrosionly boils black steel fiber, comprise undulating shape, it is characterized in that: be connected with straight line portion respectively by oblique line portion at the two ends of undulating shape, the surface of steel fiber body is provided with several anchor points, be provided with texture between the anchor point of adjacent two, steel fiber surface has one deck preservative coat.The beneficial effects of the utility model are middle is undulating shape, and two ends are that oblique line portion is connected with straight line portion, enhance steel fiber body and concrete bonding force, enhance concrete going out property of resistance to plucking; Steel fiber surface has one deck preservative coat, this preservative coat favorable anti-corrosion effect, improves the work-ing life of steel fiber body.
Description
Technical field
The utility model belongs to engineering construction field, especially relates to a kind of anticorrosionly boiling black steel fiber.
Background technology
For the steel fiber used in the concrete such as highway, bridge, tunnel, oceanographic engineering, sewage work, what generally adopt is that any chemical treatment is not done on surface, or does not plate the steel fiber of any chemical layer.The steel fiber of this structure, perishablely gets rusty, and therefore work-ing life is short, and cost is high; Steel fiber and concrete bonding effect undesirable, all easily pull in steel fiber and concrete bonding state, tension, anti-shear ability are more weak.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, long service life, favorable anti-corrosion effect and not easily unsticking in concrete, improves the anticorrosion of concrete bending performance and boils black steel fiber, be especially suitable on the concrete of construction work.
The technical solution of the utility model is: one is anticorrosion boils black steel fiber, comprise undulating shape, be connected with straight line portion respectively by oblique line portion at the two ends of undulating shape, the surface of steel fiber body is provided with several anchor points, be provided with texture between the anchor point of adjacent two, steel fiber surface has one deck preservative coat.
Further, described anchor point is that depression is distributed in steel fiber surface.
Further, described preservative coat is that steel fiber body boils casting skin layer by what obtain in polypropylene plastics feed liquid.
The advantage that the utility model has and positively effect are: owing to adopting technique scheme, centre is undulating shape, and two ends are that oblique line portion is connected with straight line portion, enhance steel fiber body and concrete bonding force, enhance concrete going out property of resistance to plucking; Steel fiber surface there is one deck preservative coat, the favorable anti-corrosion effect of this preservative coat, improve the work-ing life of steel fiber.

Fig. 2 is cut-away view of the present utility model.
In figure:
1, undulating shape 2, oblique line portion 3, straight line portion
4, anchor point 5, texture 6, preservative coat
7, steel fiber body
Embodiment
As Fig. 1, shown in 2, the technical solution of the utility model is: one is anticorrosion boils black steel fiber, comprise undulating shape 1, be connected with straight line portion 3 respectively by oblique line portion 2 at the two ends of undulating shape 1, waviness is set in the middle part of steel fiber body 7, steel fiber body 7 and concrete bonding force are strengthened, not easily unsticking in concrete, steel fiber body 7 two ends are that oblique line portion 2 is connected with straight line portion 3, in concrete loading process, steel fiber body 7 is pulled off instead of extracts, improve concrete going out property of resistance to plucking, the surface of steel fiber body 7 is provided with several anchor points 4, anchor point 4 is surperficial for depression is distributed in steel fiber body 7, texture 5 is provided with between the anchor point 4 of adjacent two, the concrete of such activeness and quietness, improve concrete bending performance, one deck preservative coat 6 is had on the surface at steel fiber body 7, this preservative coat 6 is by polypropylene plastics feed liquid by shaping steel fiber body 7, on the steel fiber of thermalization, securely hold steel wire, obtain boiling casting skin layer, i.e. preservative coat, improve the work-ing life of steel fiber body 7, cost is low simultaneously.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
Claims (3)
1. one kind is anticorrosionly boiled black steel fiber, comprise undulating shape, it is characterized in that: be connected with straight line portion respectively by oblique line portion at the two ends of undulating shape, the surface of steel fiber body is provided with several anchor points, be provided with texture between the anchor point of adjacent two, steel fiber surface has one deck preservative coat.
2. one according to claim 1 is anticorrosion boils black steel fiber, it is characterized in that: described anchor point is that depression is distributed in steel fiber surface.
