Description
aus pyramidenförmigen Elementen als Zwischenschicht für Platten und gewölbte Schalenmade of pyramid-shaped elements as an intermediate layer for plates and curved shells
Die Erfindung betrifft die Konstruktion von dreidimensionalen Gittern aus pyramidenförmigen Elementen, wobei diese Elemente drei-, vier- oder sechskantig gestaltet sein können und miteinander verbunden sind. Die Spitzen der pyramidenförmigen Elemente können abgeflacht sein. Diese Konstruktion soll als Zwischenschicht für die Herstellung von Platten und gewölbten Schalen verwendet werden. (Siehe Fig. 1)The invention relates to the construction of three-dimensional grids made of pyramid-shaped elements, whereby these elements can be designed with three, four or six edges and are connected to one another. The tips of the pyramid-shaped elements can be flattened. This construction is intended to be used as an intermediate layer for the production of plates and curved shells. (See Fig. 1)
Diese dreidimensionale Gitter haben die gleiche Funktion wie die Waben bei Wabenplatten oder wie die Schaumstoffe und andere poröse Materialien bei Sandwichplatten. Sie dienen als Verbindungsschicht zwischen der oberen und unteren Fläche und übertragen hauptsächlich senkrecht wirkende Kräfte.These three-dimensional grids have the same function as the honeycombs in honeycomb panels or as the foams and other porous materials in sandwich panels. They serve as a connecting layer between the upper and lower surfaces and mainly transfer vertical forces.
Waben und Schaumstoffe als Zwischenschichten werden mit den Oberflächen durch Kleben bzw. Löten verbunden. Diese beiden Verbindungsarten haben einige Nachteile: Sie benötigen eine komplizierte und aufwendige Technologie, die Verbindungsstellen sind auf die Qualität der Verbindung unzureichend überprüfbar und unterliegen besonders an den Klebestellen Alterungserscheinungen. Aus diesen Gründen haben solche Platten bisher nur eine begrenzte Anwendung gefunden.Honeycombs and foams as intermediate layers are connected to the surfaces by gluing or soldering. These two types of connection have some disadvantages: they require complicated and expensive technology, the connection points cannot be adequately checked for the quality of the connection and are subject to aging, particularly at the bonding points. For these reasons, such panels have so far only found limited use.
Der Erfindung liegt die Aufgabe zugrunde, eine solche Gestaltung der Zwischenschicht vorzuschlagen, die die obenbeschriebenen Nachteile beseitigt und eine kostengünstige Massenproduktion ermöglicht.The invention is based on the object of proposing such a design of the intermediate layer that eliminates the disadvantages described above and enables cost-effective mass production.
Die vorgeschlagene Konstruktion der Zwischenschicht nach Schutzanspruch 1 in Form eines dreidimensionalen Gitters aus drei-, vier- oder sechskantigen pyramidenförmigen Elementen mit abgeflachten Spitzen gestattet, die Nachteile, die den Waben- und Sandwichplatten immanent sind, durch punktuelle Verbindung der Gitterspitzen mit den Oberflächen auszuschließen und ermöglicht ein Herstellungsverfahren, das eine Massenproduktion zuläßt, da an die Spitzen der dreidimensionalen Gitter ein direkter Zugang, z.B. durch Schweißelektroden, von beiden Oberflächenseiten gewährleistet ist.The proposed construction of the intermediate layer according to claim 1 in the form of a three-dimensional grid made of three-, four- or six-edged pyramid-shaped elements with flattened tips makes it possible to eliminate the disadvantages inherent in honeycomb and sandwich panels by connecting the grid tips to the surfaces at specific points and enables a manufacturing process that allows mass production, since direct access to the tips of the three-dimensional grids, e.g. by welding electrodes, is guaranteed from both surface sides.
Eine vorteilhafte Ausgestaltung der Konstruktion ist im Schutzanspruch 2 angegeben. Das Abflachen der Spitzen der pyramidenförmigen Elemente nach Schutzanspruch 2 ermöglicht die Vergrößerung der Kontaktflächen und somit der Verbindungsflächen mit den Außenflächen, was besonders für die Kraftübertragung günstig sein kann.An advantageous embodiment of the construction is specified in claim 2. The flattening of the tips of the pyramid-shaped elements according to claim 2 enables the contact surfaces and thus the connection surfaces with the outer surfaces to be enlarged, which can be particularly advantageous for the transmission of force.
Eine weitere vorteilhafte Ausgestaltung der Erfindung ist in Schutzanspruch 3 angegeben. Die Öffnungen an den abgeflachten Spitzen der pyramidenförmigen Elemente nach Schutzanspruch 3 erlauben, weitere Verbindungsarten wie Vernieten, Verschrauben u.a. zu verwenden. Damit werden die Anwendungsmöglichkeiten für dreidimensionale Gitter aus pyramidenförmigen Elementen erweitert.A further advantageous embodiment of the invention is specified in claim 3. The openings on the flattened tips of the pyramid-shaped elements according to claim 3 allow other types of connection such as riveting, screwing, etc. to be used. This expands the application possibilities for three-dimensional grids made of pyramid-shaped elements.
Die Ausfuhrungsbeispiele der Erfindung sind anhand der Figuren 1 bis 7 erläutert. Sie zeigen:The embodiments of the invention are explained using Figures 1 to 7. They show:
