    The present invention is concerned with a steel fiber for reinforcing concrete. The steel fiber according to the present invention is a needle-shaped chip resulting from directly machining a steel ingot material. The fiber has a wrinkled surface with a plurality of rugged waves along the length of the fiber. This new production employs a plain milling cutter having a plurality of cutting edges of negative rake angle and twist angle with respect to an axis of the cutter for machining the ingot material by a down-cut milling under conditions of high speed and short depth of cut.

    专利说明:

    The invention relates to reinforcing elements used for the manufacture of dispersion-reinforced reinforced concrete structures.
    The reinforcing element for d.spersnrgo reinforcement of concrete, made in the form of a piece of wire with bends of various shapes at the ends of l J.
    Also known is a reinforcing element of the same purpose, made in the form of a metal strip with broadening or bending at the ends 2,
    These reinforcing elements are difficult to manufacture, as they require special technological operations to form their end parts. The closest to the invention is a reinforcing element for dispersed reinforcement of concrete, containing a steel strip with a wavy relief of the NW surface.
    The wavy relief of the surface of this reinforcing element is obtained by deforming it in the transverse direction, therefore, when mixed in Betol, such reinforcing elements interlock, form lumps and unevenly spread in the concrete mix, which reduces the strength of the reinforced concrete.
    The purpose of the invention is to increase the strength of reinforced concrete.
    The goal is achieved by the fact that in the reinforcing element for dispersed reinforcement of concrete containing a steel strip with a wavy relief of the surface, the strip is made in the form of needle-shaped chips, while the wave of the rail is oriented along its length with an inclination to the longitudinal axis.
    One of the longitudinal edges of the chips can be made pointed
    FIG. 1 shows a part of the reinforcing element, a general view; in fig. 2 - its cross section.
    The reinforcement element is a needle-shaped chip 1 with a wavy surface relief formed by thin folds 2 and rough waves 3 of different height, oriented along the length of the chip inclined to its longitudinal axis. One of the longitudinal edges of the 4 chips is made pointed. Part of the surface 5 of the chip is made flat. Chips are formed by treating the surface of a steel ingot with a cylindrical cutter.
    When mixed with the concrete mix, the reinforcing elements are evenly distributed in the mix without the formation of lumps, which increases the strength of the reinforced concrete. The strength of concrete also increases due to the fact that reinforcing elements have an increased surface due to inclined folds and waves, which increases adhesion to concrete.
