Dazu zeigt Figur 1 einen Schnitt durch eine erfindungsgemäße Verbundplatte, bei der sich eine aus Hartschaum bestehende Leichtstoffschicht 3 als Zwischenschicht zwischen der oberen Tragplatte 1 und der unteren Tragplatte 2 angeordnet ist. Die Tragplatten 1 und 2 werden vorzugsweise als Hartfaserplatten ausgeführt, können aber auch aus anderen Materialien, beispielsweise aus Holz bestehen. Figure 1 shows a section through a composite panel according to the invention, in which a lightweight material layer 3 made of rigid foam is arranged as an intermediate layer between the upper support panel 1 and the lower support panel 2. The support panels 1 and 2 are preferably made of hardboard, but can also be made of other materials, for example wood.

In Figur 2 ist eine Ausführungsform dargestellt, bei der in der Leichtstoffschicht 3 Hohlräume 8 zur Aufnahme von Funktionselementen wie Kabelkanälen, Rohrleitungen und dergleichen angebracht sind. Ferner befindet sich in der Leichtstoffschicht 3 ein Verstärkungsprofil 9, das zur Verstärkung der Tragfähigkeit der Verbundplatte dient. Die aus Leichtstoffschicht 3 wurde eingebracht, indem zunächst weichkonsistenter Leichtstoff unter Druck zwischen die obere Tragplatte 1 und die untere Tragplatte 2 eingebracht wurde, dort selbständig aufgeschäumt ist und beim Erhärten die beiden Tragplatten 1 und 2 gegenseitig verklebt hat. Figure 2 shows an embodiment in which hollow spaces 8 are provided in the lightweight material layer 3 to accommodate functional elements such as cable ducts, pipes and the like. Furthermore, there is a reinforcing profile 9 in the lightweight material layer 3, which serves to increase the load-bearing capacity of the composite panel. The lightweight material layer 3 was introduced by first introducing soft, consistent lightweight material under pressure between the upper support plate 1 and the lower support plate 2, where it foamed up independently and, when it hardened, bonded the two support plates 1 and 2 to one another.

Figur 3 erläutert ein Anwendungsbeispiel, bei dem die Verbundplatte mit einer aufgeklebten Steinplatte 4, die aus Kompositstein oder aus Naturstein besteht, versehen ist. Es ist natürlich auch möglich, eine Steinplatte aus Werkstein zu verwenden. Die Dicke der Steinplatte 4 beträgt 13 mm, die Figure 3 illustrates an application example in which the composite panel is provided with a glued-on stone panel 4 made of composite stone or natural stone. It is of course also possible to use a stone panel made of ashlar. The thickness of the stone panel 4 is 13 mm, the

Dicke der beiden Tragplatten beträgt jeweils 4 mm und die Dicke der Hartschaum-Zwischenschicht 3 beträgt 22 mm. Die Gesamtstärke der Verbundplatte beträgt exakt 40 mm.

Es ist auch möglich, als Frontplatte 7 KunststoffelementeThe thickness of the two supporting plates is 4 mm each and the thickness of the rigid foam intermediate layer 3 is 22 mm. The total thickness of the composite plate is exactly 40 mm. A front plate 7 is arranged on the front of the composite plate, which is made of the same material as the stone plate 4. It is also possible to use plastic elements as the front plate 7

Dies ist insbesondere dann angebracht, wenn die Verbundplatte dampfdicht ausgebildet werden soll, was beispielsweise für Küchenarbeitsplatten über Spülmaschinen vorteilhaft ist. 10to be used. The lower support plate 2 is expediently provided with an aluminum layer 10. This is particularly appropriate if the composite plate is to be made vapor-tight, which is advantageous for kitchen worktops above dishwashers, for example. 10
