Description

Die Erfindung betrifft ein Vakuum-Isolations-Element, bei dem ein inneres Bauteil mehrere Hohlräume aufweist und mit einer Hülle versehen ist und ein Verfahren zu seiner Herstellung.The The invention relates to a vacuum insulation element in which an inner Component several cavities has and with a shell is provided and a method for its preparation.

Das erfindungsgemäße Paneel ist für den Einsatz im Bauwesen geeignet.The inventive panel is for suitable for use in construction.

Bisher bekannte Vakuum-Isolationspaneele werden in Geräten, beispielsweise in Kühlschränken und Tiefkühltruhen verwendet und neuerdings auch im Bauwesen eingesetzt. Ein Vakuum-Isolations-Paneel besteht im Wesentlichen aus einem inneren Bauteil in Form eines Kernmaterials, welches in einer Vakuumkammer in eine gasdichte Hüllfolie eingeschweißt wird. Das dabei entstehende Vakuum unterbindet die Wärmeleitung des im Dämmstoff eingeschlossenen Gases, so dass eine sehr hohe Wärmedämmung bei verhältnismäßig geringen dicken Abmessungen erreicht wird. Bei den bekannten Paneelen ist nachteilig, dass diese mit einer Folie umhüllt werden müssen, die extrem gasdicht sein muss. Dennoch verliert das Vakuum mit der Zeit durch Ausgasung und Undichtigkeit an Qualität.So far known vacuum insulation panels are used in appliances, such as refrigerators and Freezers used and recently used in construction. A vacuum insulation panel consists essentially of an inner component in the form of a Core material, which in a vacuum chamber in a gas-tight envelope film shrink wrapped becomes. The resulting vacuum prevents heat conduction in the insulating material enclosed gas, so that a very high thermal insulation at relatively low thick dimensions is achieved. In the known panels disadvantageous that they must be wrapped with a film, the must be extremely gas-tight. Nevertheless, the vacuum loses over time through outgassing and leakage of quality.

Die Erfindung liegt der Aufgabe zugrunde, ein Vakuum-Isolations-Element der eingangs genannten Art anzugeben, das kostengünstig herstellbar ist und für den Einsatz im Bauwesen besonders geeignet ist.The Invention is the object of a vacuum insulation element specify the type mentioned, the inexpensive to produce is and for the use in construction is particularly suitable.

Eine bevorzugte Ausführung sieht vor, dass die Hohlräume in zwei übereinander liegenden Reihen angeordnet sind, wobei die Hohlräume der oberen Reihe gegenüber den Hohlräumen der unteren Reihe seitlich versetzt angeordnet sind. Es ist auch möglich, dass das innere Bauteil aus einem vorgefertigten Wabenmaterial besteht. Dabei weisen die Zwischenwände der einzelnen Waben Öffnungen auf, die es ermöglichen, ein Vakuum in allen Wabenräumen zu erzeugen.A preferred embodiment provides that the cavities in two on top of each other lying rows are arranged, wherein the cavities of opposite the top row the cavities the lower row are arranged laterally offset. It is also possible that the inner component consists of a prefabricated honeycomb material. Here are the partitions the individual honeycomb openings on that make it possible a vacuum in all honeycomb spaces to create.

Als Laminatwerkstoff wird Glasvlies, Glasgewebe, Metallgewebe oder schwer entflammbarem Papier verwendet. Diese Materialien können auch in Kombination eingesetzt werden.When Laminate material becomes glass fleece, glass fabric, metal mesh or heavy used flammable paper. These materials can also be used in combination.

Die im Bypass aufgebrachten, aus verschiedenen Werkstoffen bestehenden Laminate dienen der Verringerung der Permeabiliät. Dadurch wird die Zeit zur Aufrechterhaltung eines ausreichenden Vakuums verlängert.The Applied in the bypass, made of different materials Laminates serve to reduce permeability. This is the time to Maintaining a sufficient vacuum extended.

Eine vorteilhafte Ausführung sieht vor, das Vakuum durch eine an der Einsatzstelle der Paneele integrierte Vakuumpumpe in bestimmten Zeitabständen nachzubessern. Hierzu wird das Paneel mit Steuerungseinrichtungen gekoppelt, welche das Vakuum überprüfen und gegebenenfalls nachbessern.A advantageous embodiment provides the vacuum through a built-in at the point of use of the panels Improve vacuum pump at certain intervals. For this For example, the panel is coupled to control devices incorporating the Check vacuum and correct if necessary.

Vorteilhaft ist dabei, dass die im Bypass beim Extrudieren auflaminierten Schichten eingefärbt sein können. Dies ermöglicht es beispielsweise Hallenbauten mit selbst tragenden Wänden zu errichten, die ohne zusätzliche Anstriche ein bestimmtes Farbdesign aufweisen.Advantageous is that the layers laminated in the bypass during extrusion colored could be. this makes possible for example, hall buildings with self-supporting walls too to build without additional Paintings have a specific color design.
