Description

Die Erfindung betrifft einen Leichtbaukern für Raumwände, Leichtbaudecken, Türen, Möbel oder sonstige Flächentragelemente, bestehend aus einem zweifach gekrümmten Schalentragwerk mit periodisch wiederkehrenden, dreidimensionalen Erhebungen und Vertiefungen, die in eine Werkstoffplatte eingeprägt sind.The Invention relates to a lightweight core for room walls, Lightweight ceilings, doors, furniture or other surface support elements, consisting of a double-curved shell structure with periodically recurring, three-dimensional elevations and Depressions, which are embossed in a material plate.

Derartige Leichtbaukerne werden im Bauwesen in Sandwichbauweise mit zwei Deckschichten kombiniert, um Flächentragelemente wie Raumwände, Möbelwände, Türen, Leichtbaudecken oder dergleichen herzustellen. Aufgrund des geschilderten Aufbaus gewährleisten die Leichtbaukerne trotz ihres geringen Gewichtes eine hervorragende Steifigkeit sowie einen wirksamen Wärme- und Schallschutz.such Lightweight cores are combined in construction in sandwich construction with two layers, around supporting elements such as room walls, furniture walls, Doors, lightweight ceilings or the like produce. by virtue of of the described construction ensure the lightweight cores despite its low weight, excellent stiffness as well Effective heat and sound insulation.

Gegenstand der DE 10 2004 024 878 A1 ist ein Leichtbaukern der eingangs umrissenen Bauart, bei dem die kuppelartigen Erhebungen und Vertiefungen im Wesentlichen als Halbkugeln ausgebildet sind. Die daran angrenzenden Deckschichten haben wannenartige Einprägungen, in die die halbkugelförmigen Erhebungen und Vertiefungen des Leichtbaukerns eingreifen.Subject of the DE 10 2004 024 878 A1 is a lightweight core of the initially outlined type, in which the dome-like elevations and depressions are formed substantially as hemispheres. The adjacent outer layers have trough-like embossments, in which engage the hemispherical elevations and depressions of the lightweight core.

Aus dem Gebrauchsmuster 20 2008 006 174 ist ein ähnlicher Leichtbaukern bekannt, bei dem die Erhebungen und Vertiefungen obere und untere, ebene Begrenzungsflächen haben, die flächig an der jeweiligen Deckschicht anliegen. Das bedeutet, dass alle Begrenzungsflächen exakt in ein und derselben Ebene liegen müssen, um eine lückenlose Verbindung mit den Deckschichten zu gewährleisten.Out the utility model 20 2008 006 174 is a similar lightweight core known, in which the elevations and depressions upper and lower, level Have boundary surfaces that are flat at the respective Cover layer abut. This means that all boundary surfaces must be exactly in the same plane, around one to ensure complete connection with the outer layers.

Der Erfindung liegt die Aufgabe zugrunde, einen Leichtbaukern zur Verfügung zu stellen, dessen Erhebungen und Vertiefungen nicht, wie aus dem Stand der Technik bekannt, mit den angrenzenden Deckschichten über Berührungsflächen verbunden sind, sondern eine linienförmige Verbindung herstellen, die größere Fertigungstoleranzen erlaubt.Of the Invention is based on the object, a lightweight core available to ask, its elevations and depressions not, as from the state known in the art, with the adjacent facings over Contact surfaces are connected, but a make linear connection, the larger Manufacturing tolerances allowed.

Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, dass die Erhebungen und Vertiefungen obere bzw. untere Begrenzungsringe aufweisen, die jeweils eine kraterförmige Mulde umschließen.to Solution to this problem is according to the invention provided that the elevations and depressions upper or lower Contain boundary rings, each having a crater-shaped Enclose the hollow.

Dabei ist es von besonderem Vorteil, wenn die Begrenzungsringe einen linienförmigen Kontaktbereich zur angrenzenden Deckschicht bilden.there it is of particular advantage if the boundary rings a linear Form the contact area to the adjacent cover layer.

Diese Lösung hat anstelle der durchgehenden, ebenen oder halbkugeligen Begrenzungsflächen zwischen dem Leichtbaukern und den angrenzenden Deckschichten eine Linienberührung, die einen definierte Verbindung zwischen Kernschicht und Deckschicht gewährleistet.These Solution has instead of continuous, even or hemispherical Boundary surfaces between the lightweight core and the adjacent Overlays a line contact, the one defined Guaranteed connection between core layer and cover layer.

Die Erfindung ist nachstehend an einem Ausführungsbeispiel erläutert, das in der Zeichnung dargestellt ist. Es zeigen:The Invention is hereinafter an embodiment explained, which is shown in the drawing. Show it:

1 die perspektivische Ansicht eines Leichtbaukerns gemäß der Erfindung, 1 the perspective view of a lightweight core according to the invention,

2 eine Seitenansicht in Richtung des Pfeiles II der 1, 2 a side view in the direction of arrow II the 1 .

3 einen Querschnitt in der Ebene III-III der 1 und 3 a cross section in the plane III-III of 1 and

4 ein Schnittdiagramm zur Darstellung einer Erhebung und einer sich daran anschließenden Vertiefung des Leichtbaukerns. 4 a sectional diagram illustrating a survey and a subsequent deepening of the lightweight core.

Der in den Figuren dargestellte Leichtbaukern 10 gemäß der Erfindung kann aus verpressten Fasermaterialien, beispielsweise Holzfaserwerkstoffe oder Hanffasermaterial mit Bindemitteln wie etwa Harz, aus Kunststoff oder auch einem Leichtmetall durch Prägen hergestellt werden. Er hat die Form eines zweifach gekrümmten Schalentragwerks mit in gleichbleibendem Abstand wiederkehrenden, dreidimensionalen Erhebungen 12 und Vertiefungen 14, wobei jeder Erhebung 12 eine Vertiefung 14 und umgekehrt gegenüberliegt. Damit ergibt sich ein wabenförmiger Aufbau. Die einander benachbarten Erhebungen 12 einerseits und die Vertiefungen 14 andererseits sind durch Sattelflächen 16 miteinander verbunden.The lightweight core shown in the figures 10 According to the invention can be made of pressed fiber materials, such as wood fiber materials or hemp fiber material with binders such as resin, plastic or even a light metal by embossing. It has the shape of a double-curved shell structure with constantly spaced, three-dimensional elevations 12 and depressions 14 , each survey 12 a depression 14 and vice versa. This results in a honeycomb structure. The adjacent surveys 12 on the one hand and the depressions 14 on the other hand are by saddle surfaces 16 connected with each other.

Die Erhebungen 12 und Vertiefungen 14 können, wie in den Beispielen der 1 bis 3 gezeigt, einen periodisch gleich bleibenden Abstand oder aber auch einen variierenden Abstand voneinander haben.The surveys 12 and depressions 14 can, as in the examples of 1 to 3 shown to have a periodically constant distance or even a varying distance from each other.

Wie aus den 3 und 4 hervorgeht, haben die Erhebungen 12 und die Vertiefungen 14 obere bzw. untere Begrenzungsringe 18, die jeweils eine im wesentlichen kreisförmige Aussparung umschließen, die im dargestellten Ausführungsbeispiel die Form einer kraterförmigen Mulde 20 hat. Daraus ergibt sich im Idealfall der 4 ein linienförmiger Kontaktbereich 22 zu einer angrenzenden Deckschicht 24 (vgl. 3). In der Praxis wird sich aufgrund der Verpressung beim Verleimen oder Verkleben zwischen dem Leichtbaukern 10 und den beiden Deckschichten 24 ein Kontaktbereich 22 einstellen, der aus einer jeweils sehr schmalen, ringförmigen Begrenzungsfläche besteht.Like from the 3 and 4 indicates the surveys have 12 and the depressions 14 upper or lower boundary rings 18 each enclosing a substantially circular recess, in the illustrated embodiment, the shape of a crater-shaped trough 20 Has. This results in the ideal case of 4 a linear contact area 22 to an adjacent cover layer 24 (see. 3 ). In practice, due to the compression during gluing or gluing between the lightweight core 10 and the two cover layers 24 a contact area 22 set, which consists of a very narrow, annular boundary surface.
