  • the proposed method can be carried out easily and inexpensively. It can be assumed that a conventional base or a formwork table for producing a concrete formwork panel.
  • reinforcing frameworks for the carrier elements are placed on the substrate in such a way that penetration areas formed therein are arranged in alignment, so that shaped cores can be driven through the penetration areas.
  • Forming elements are also arranged between the reinforcing frames.
  • Concrete concrete ceiling element concrete poured into the formed between the mold elements elongated mold cavities. The cast-in concrete spreads over the base and forms the concrete shuttering panel as well as the support elements. The process does not require a lot of time. It can be done relatively inexpensively.

  • the concrete formwork panel is cast before arranging the mold elements.
  • the concrete formwork panel is cast before arranging the mold elements.
  • the mandrels are retracted from two opposite sides of the mold by the passage areas. This allows in particular pulling the mandrels in opposite directions. This facilitates demolding. This is especially true when retracted from opposite sides

  • the mold elements are placed on the retracted mandrels.
  • the form elements can be lowered for example with a crane on the mandrels.

  • the mold elements may have recesses provided at regular intervals at an upper side facing away from the mold. Such recesses are used to make recesses in the support elements, which serve for inserting reinforcing bars.
  • the mold elements have at their ends from the bottom extending extensions, so that thus a concrete ceiling element can be produced, in which the support elements extend beyond a side wall of the concrete formwork panel addition.
  • the supernatant of the carrier elements is expediently 2 to 10 cm, preferably 3 to 8 cm.
  • a device for shaking the mandrels is provided. This allows easier demolding. Furthermore, a device for automatically performing a pulling movement of the mold cores and a simultaneous movement, preferably lifting movement, of the mold elements can be provided. A simultaneous and automatically coordinated movement of the mandrels and the form elements allows a particularly gentle demolding. An undesirable deformation, in particular of the carrier elements, is avoided.
  • a device for filling the elongated formed between the mold elements is provided. Stretched interspaces with concrete provided. With such a device, the entire required for the production of concrete ceiling element concrete can be cast. But it is also possible to first cast the concrete formwork panel with this device and then to produce the intermediate spaces with concrete to produce the support elements.
