    vier Enden, darunter ein oberes Ende und ein dem oberen Ende gegenüberliegendes unteres Ende, ein vertikales rechtes Ende und ein vertikales linkes Ende,
    wobei das obere Ende eine vorstehende Kante entlang der Länge der Platte, eine Aussparung entlang der Länge der Platte und einen Hohlraum umfasst, der in der genannten Aussparung entlang der Länge der Platte angeordnet ist;
    wobei das untere Ende eine vorstehende Kante entlang der Länge der Platte umfasst, die in einer Trichterform endet, um die Verbindungsstangen aus Metall zusammenzudrücken, wenn sie auf eine andere Platte aufgesetzt werden.
  15. Verfahren für den Zusammenbau des isolierenden Betonschalungssystems mit Isolierplatten (1,5) und Verbindungselementen nach einem der Ansprüche 1-12, umfassend: mindestens zwei Platten (1,5); mindestens zwei Profile (3); eine oder mehrere Verbindungsvorrichtungen (2,7); wobei das Verfahren die folgenden Schritte umfasst:
