  • Each formwork panel has a formwork front side for attaching formwork elements and a formwork rear side, with the formwork rear sides of the formwork panels facing one another in the folded state of the formwork device.
  • the formwork devices are fitted on a substrate in the unfolded state, with formwork elements being attached to the formwork fronts of the horizontally aligned formwork panels that are pointing upwards. Thereafter, the formwork devices are raised with the aid of a lifting device, whereby the rear side of the formwork panels fold up.
  • the formwork panels are so between two Partition walls positioned so that cavities form between the formwork fronts, the formwork elements and the partition walls, which are filled with concrete.
  • the precast concrete parts can be hardened within the battery mold.

  • the formwork device can be arranged in a drying position with the second end regions of the formwork elements spread apart outside the space between the battery formwork.
  • the spreading device engages the second end regions - opposite the pivotable connection between the formwork elements - at least while the shuttering device is being set down with the component to be dried on the substrate.

  • a coupling rod 35 which is connected to a compression spring 36, is arranged on a side of the pivot bearing 34 opposite the hook 32.
  • the compression spring 36 extends into the receptacle 25 of the lever element 20, on which the hook 32 is arranged, so that when the guide pin is received in the receptacle 25, the compression spring 36 is actuated, whereby the coupling rod 35 connected to the compression spring 36 via the pivot bearing 34 The hook 32 is released from the receiving device 33.
  • the formwork elements 11 of a formwork device 2 according to the invention can be converted into the lying state.
  • two spreading devices 18 according to the embodiment in FIG Fig. 5 arranged on a substrate in such a way that the guide tracks 27 of the spreading devices 18 are aligned parallel to one another.
  • the formwork elements 11 After drying and removal of the precast concrete parts from the formwork elements 11, as in Fig. 6 shown, the formwork elements 11 using the lifting device 9 arranged in the standing state above the ground above the spreading devices 18.
  • the formwork elements 11 are arranged in such a way that the bolts 23, which are fastened in the bores of the connecting elements 16 and are provided as guide bolts, are positioned directly above the receiving troughs 25 of the spreading devices 18. After that, as in Fig. 7 As shown, the formwork elements 11 are lowered onto the expansion devices 18, so that the bolts 23 of the formwork elements 11 are received by the receiving troughs 25 of the expansion devices 18.
  • the shuttering elements 11 each have two bolts 23, so that the total of four bolts 23 of the shuttering elements 11 are received in the four receiving depressions 25 of the two spreading devices 18.
  • the total of four support elements 28 of the two formwork elements 11 are support bolts which are arranged above the two guide tracks 27 when the connecting elements 16 and the bolts 23 are received in the receiving troughs 25 of the spreading devices 18.
  • the support elements 28 can be designed as support rollers.
  • the total of four transfer sections 29 of the two guide tracks 27 are arranged in such a way that when the second end regions 15 of the formwork elements 11 are lowered and spread apart, the support elements 28 of the formwork elements 11 rest on the transfer sections 29 of the guide tracks 27.
  • the formwork elements 11 are lowered further, they are spread apart further by guiding the support elements 28 on the guide tracks 27, the bolts 23 moving out of the receiving troughs 25 of the spreading devices 18.
  • the formwork elements 11 are moved by means of the guide tracks 27 of the opening devices 26 from the spread-apart state of the second end regions 15 into the lying state of the formwork elements 11.
  • the formwork elements 11 can be easily cleaned and reloaded.
