  • load-carrying means is understood very comprehensively in the art today. It also includes elements incorporated in the precast concrete part, such as threaded sleeves having an anchor-like design at their lower end.

Known load-carrying means are for example fixedly arranged on the component or releasably connected thereto. The invention includes both variants. However, the invention relates here to a load-receiving means, in which the two ends of a cable sleeve are pressed into a tube press clamp substantially parallel to each other, lying in this.

  • the cable deflection serves to deflect the cable section of the cable eye, which adjoins the pipe press clamp in a deflection region, following the rounding.
  • a further rounding is provided in addition to the cable deflection on the tube press clamp in the component.

  • a recess is provided in the area of the component in which the cable piece exits, in the boundary surface of the component itself.
