Abstract
Leichtbaukern für Raumwände, Leichtbaudecken, Türen, Möbel oder sonstige Flächentragelemente, bestehend aus einem zweifach gekrümmten Schalentragwerk mit periodisch wiederkehrenden, dreidimensionalen Erhebungen (12) und Vertiefungen (14), die in eine Werkstoffplatte eingeprägt sind, dadurch gekennzeichnet, dass die Erhebungen (12) und Vertiefungen (14) obere bzw. untere Begrenzungsringe (18) aufweisen, die jeweils eine kraterförmige Aussparung oder Mulde (20) umschließen.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 (12) and depressions (14) which are embossed in a material plate, characterized in that the elevations (12) and depressions (14) have upper and lower limiting rings (18), each enclosing a crater-shaped recess or depression (20).
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.

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:
