  • the following is according to Fig. 2 lifted the concrete form 10 upwards from the molding. In this case, the stamp plate 15 continues to press against the top of the molding, so that it remains lying on the backing board 12 and is not raised with the concrete mold 10.
  • the following is according to Fig. 3 also the punch 14 is raised with the stamp plate 15, so that the molding or the plasterboard 16 is free on the base board 13. The backing board can then be transported with the molding lying on it for drying.
  • the filled concrete can also be subjected to a compaction process.
  • a vibrating table can be located beneath the base board 13, which vibrates the concrete form 10.
  • the mold walls 12 are used, as shown in the figures, to form upright side surfaces 17 of the plasterboard 16 to be produced.

  • the paving slabs 16 may be laid to a soil cover 26. Within the soil cover 26 adjacent paving slabs 16 are spaced apart, to form preferably regular transverse and longitudinal joints. Depending on the arrangement of the spacers 25, the paving slabs 16 may be laid so that spacers 25 adjacent paving slabs 16 abut each other or offset from each other so that they each receive contact on a side surface 17 of the adjacent paving slab 16. In this way, different joint widths arise. After laying the paving slabs, the joints are filled by a suitable joint filling material, so that the spacers 25 are preferably no longer visible.
  • the paving slabs 16 are preferably rectangular or square in plan. Preferred ground plan dimensions of the paving slab 16 are 600 mm x 600 mm, 600 mm x 450 mm, 600 mm x 300 mm, 450 mm x 450 mm or 300 mm x 300 mm. It is understood that the plasterboard 16 may also have irregular planforms.
