Definitions

  • the present invention relates to a reinforcing steel according to the preamble of patent claim 1, a method for its production according to patent claim 6 and a device for carrying out the method according to patent claim 7.
  • AT-B 318 207 states that reinforcing steels with a circular cross section are connected to one another in one piece and without being twisted, so that the cross-sectional areas delimited by two or three circles are connected to one another in a width that corresponds to at least half the diameter of the circles.
  • the rods lie directly against one another, moreover the rods are connected to one another by webs arranged transversely to the longitudinal axes.
  • the strength can, however, be achieved by bars which are arranged at a distance from one another and are connected to one another over their entire length by a web wall lying in the direction of the bar longitudinal axis, as are known from US Pat. No. 2,317,454 or US Pat. No. 2,418,383 , improve.
  • the transverse ribs which are also provided in the following result in a relatively high material consumption.
  • the staggered knobs on both sides of the web wall, as provided in US Pat. No. 2,317,454 also mean an increased material expenditure, which cannot contribute to the strength.
  • the web wall 3 has through holes 4, which are preferably arranged equidistantly.
  • the steel wires 1, 2 are circular and have the same diameter d.
  • the two wires 1, 2 are spaced apart from one another by a distance equal to d and the web wall 3 has a thickness of d / 2, as is also indicated in FIG. 1.
  • a reinforcement bar according to FIG. 1 has a section modulus that is five times greater, namely 31.5 cm 3 only an amount of 3.03 cm for d and therefore a meter weight of 14.9 kg / m. This comparison shows that with a larger section modulus a saving of about 50% can be achieved.
  • Such constructions are, for example, the girders in cavity structures, which are installed after the rock has broken out and form a support for the excavated vault until the reinforcement is covered with shotcrete.
  • FIGS. 2 and 3 An example of a reinforcement perpendicular to reinforcing bars according to FIG. 1 is shown in FIGS. 2 and 3.
  • Two reinforcing bars 10, 20 are arranged flat next to one another and a wire 30 with a smaller diameter than d is welded in between these two reinforcing bars 10, 20.
  • FIG. 4 A further variant is shown in FIG. 4, in which, instead of the meandering wire 30 in FIG. 3, a further reinforcement bar 40 is welded perpendicularly to the plane in which the web walls 3 of the two reinforcement bars 10, 20 are welded between them. Such an arrangement could in certain cases be used directly as a belt carrier.
  • the holes in the web wall 3 are punched simultaneously with the hot rolling process.
  • This punching can be carried out from one side via a counterholder, or rollers with opposing cams can be provided in order to impress depressions so that a membrane wall exists remains, which can then be knocked out. However, knocking out takes place in the same operation as rolling.
