Abstract

Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung eines kerngedämmten Betonfertigteils sowie ein kerngedämmtes Betonfertigteil. Bei herkömmlichen Verfahren wird eine Lage eines aus Dämmmatten bestehenden Dämmmaterials auf eine noch flüssige Betonschicht aufgebracht. Beim Erhärten verbinden sich die beiden Schichten zu einem Rohdämmelement, welches mit der Seite der Dämmschicht auf eine weitere flüssige Betonschicht aufgelegt wird. Durch zusätzlich eingebrachte Verbindungsmittel entsteht eine feste Verbindung zwischen den beiden Betonschichten. Durch die Verwendung von Dämmmatten birgt das Verfahren jedoch das Risiko von Unterschreitungen von Mindestdicken der Betonschichten einerseits sowie von Lufteinschlüssen andererseits. Zum Lösung wird in einer ersten Schalung eine Betonschicht gegossen, mit Verbindungsmitteln versehen und teilweise erhärtet. In einer zweiten Schalung werden zunächst eine zweite Betonschicht und auf diese noch flüssige Betonschicht eine Schicht Mineralschaum ausgebracht. Das zuerst hergestellte Betonelement wird nun auf die Mineralschaumschicht gelegt, wobei die Verbindungsmittel die Mineralschaumschicht durchdringen und sich beim Erhärten mit der zweiten Betonschicht verbinden, wodurch ein kerngedämmtes Betonfertigteil entsteht.The present invention describes a method for producing a core-insulated precast concrete part and a core-insulated precast concrete part. In conventional methods, a layer of insulating material consisting of insulating mats is applied to a layer of concrete that is still liquid. When hardening, the two layers combine to form a raw insulating element, which is placed with the side of the insulating layer on another liquid concrete layer. Additional fasteners are used to create a firm connection between the two concrete layers. Due to the use of insulating mats, however, the process carries the risk of falling below the minimum thickness of the concrete layers on the one hand and of air inclusions on the other. To solve this, a concrete layer is poured in a first formwork, provided with fasteners and partially hardened. A second layer of concrete is placed in a second formwork and then a layer of mineral foam is placed on top of this layer of concrete, which is still liquid. The concrete element produced first is now placed on the mineral foam layer, with the connecting means penetrating the mineral foam layer and connecting with the second concrete layer as it hardens, resulting in a core-insulated precast concrete element.
