Es entsteht somit eine Platte, bei der die beiden Betonscheiben in einem Abstand voneinander mit Zwischenraum durch die Gitterträger gehalten sind.The pallet is then conveyed into the drying oven in step S10 and the Cured concrete. This creates a slab with the two concrete slices held at a distance from each other with space by the lattice girders are.

    In den Zwischenraum kann nun durch Einfüllen, Einblasen oder Einsaugen loses Dämmaterial, wie beispielsweise Polysterol-Kügelchen, Zellulose-Flocken oder Mineralwolle-Flocken eingefüllt werden. Alternativ kann auch PU-Schaum eingefüllt und ausgehärtet werden. Ebenso ist es möglich, dass nach dem Fertigen der unteren Betonscheibe PU-Schaum aufgefüllt und dieser ausgehärtet wird. Erst danach erfolgen die weiter oben im Schritt S6 genannten Arbeitsschritte.Loose space can now be added by filling, blowing or sucking in Insulation material such as polystyrene beads, cellulose flakes or Mineral wool flakes can be filled in. Alternatively, PU foam can be filled in and be cured. It is also possible that after finishing the bottom concrete disc filled with PU foam and this is cured. First The work steps mentioned above in step S6 then take place.
