  • the length of the reinforcing bars 22 is chosen such that they protrude statically deep enough by the reinforcing rod fixing device 3 in the reinforcing cage 19 ( Fig. 12a, b ).
  • the connection of the reinforcement device 1 is released with respect to the reinforcement cage 19, wherein the reinforcement device 1 is held on the holding adapter 46 arranged thereon by means of the crane or the drilling device in its position ,
  • the reinforcement device 1 can now be measured, in particular with regard to the desired position of the later produced reinforcement 22, wherein the reinforcement device 1 can be rotated within the casing 19 to a desired position and on the other also in their height and inclination, in particular also be adapted to the reinforcement cage 19 ( Fig. 12b, c ).
  • the reinforcement device 1 is fixed by means of an adjustment of the alignment elements 4, wherein the alignment elements 4 rest on a support ring 29 of the reinforcement cage 19. If necessary, an additional support of the reinforcement device 1 with respect to the bottom 45 surrounding the borehole 50 can also take place by means of a support device 18 (FIG. Fig. 1a ).
  • the support 18 is usually used when the reinforcement cage 19 can not be discontinued down to the foundation base of the bored pile.

  • reinforcing bars 22 are provided in further receiving openings 12 of the reinforcing bar fixing device 3 of the fixed reinforcing device 1 with securing bars 47, so that they penetrate into the still liquid concrete 23 ( Fig. 13a, b ).
  • the reinforcing device 1 can be secured against further change in position by filling the remaining cavities, ie, the casing 43 at least as far as with granular building material 51 (such as gravel, grit, ash, Granules), until the reinforcing bar fixing device 1 is completely filled with granular building material 51 and / or covered.
  • granular building material 51 such as gravel, grit, ash, Granules
  • the thus fixed reinforcement device 1 can now be solved by the crane or the drill. In addition, however, it is often also possible to separate the reinforcement device 1 before the introduction of further reinforcing rods 22 already from the crane.
  • the security rods are removed from the reinforcing bars 22 or the rebars 22 separated accordingly, so that the reinforcement device 1 can be pulled out, inter alia, by means of the holding adapter 46, the separation of the reinforcing device 1 from the cast, sufficiently hardened Concrete 23 is facilitated by means of a arranged on the bottom 16 of the reinforcing rod fixing device 3 separating film 15.
  • the bored pile 21 produced in this way has plane surfaces as well as a defined designed and aligned reinforcement 22.
  • the concrete overflow 49 lies above the lower reinforcement rod fixing element 5 (FIG. Fig. 13a ).
  • the piping 43 is pulled out by means of the crane or the drill and depending on the hardened state of the concrete with the additional use of heavy construction equipment. At the earliest, the pulling of the casing 43 after sufficient hardening of the concrete 23 can be done to a humid condition.
  • a layer-defined reinforcement 20 is obtained, so that a transverse reinforcement 37 can be easily applied to the reinforcement 20 of a plurality of bored piles 21 without any problems.
  • the reinforcement 20 is arranged in each case in intermediate spaces of the transverse reinforcement 37 and consequently also the transverse reinforcement 37 in particular can be arranged precisely ( Fig. 14 ).
  • the position-determined reinforcement 20 also allows the use of finished parts for further completion of the structure 21.
