Abstract
Description
Die Erfindung bezieht sich auf die Verbindung von gegeneinander stoßenden, aus zwei Deckschichten und dazwischenliegendem Kern bestehenden Sandwichplatten.The invention relates to the connection of each other butting, consisting of two cover layers and intermediate core existing sandwich panels.
Es ist bekannt, Sandwichplatten unter Zwischenschaltung von Profilschie nen miteinander zu verbinden. Die Schienen werden zu diesem Zweck vor dem Einbau bzw. Einkleben der Sandwichplatten zu einem Gerippe zusammen geschweißt. Hierdurch ist es möglich, die einzelnen Plattenelemente in beliebiger Reihenfolge in das Gerippe einzubauen. Dabei ist jedoch Voraussetzung, daß z.B gekrümmte Profile in der Kontur genau mit den Sandwichplatten übereinstimmen. Außerdem muß die Höhe der Profile genau der Dicke des Kerns und der Deckschichten entsprechen. Kreuzungsstellen der Profile, die ausgeklinkt und geschweißt werden müssen, sind aufwen dig und können Schweißverzug verursachen. Das Gewicht der Querspriegel, das nicht der Längssteifigkeit der Platten zugute kommt, wirkt sich nachteilig aus. Die Teilung des Gerippes muß beispielsweise beim Fahr zeugbau auf Fenster und Türen im Wagenkastensystem abgestimmt sein. Für die Profile ist eine Legierung mit besonderer Schweißeigung erforder lich. Das Gerippe bewirkt außerdem Steifigkeitssprünge, die eine ungün stige sekundäre Belastung der Deckbleche hervorrufen, während die Profile unerwünschte Wärmebrücken bilden.It is known sandwich panels with the interposition of profiling to connect with each other. The rails are used for this purpose the installation or gluing of the sandwich panels together to form a framework welded. This makes it possible to in the individual plate elements in any order in the framework. However, it is Prerequisite that, for example, curved profiles in the contour exactly match the Sandwich panels match. In addition, the height of the profiles must be exact correspond to the thickness of the core and the cover layers. Crossing points the profiles that have to be released and welded are expensive dig and can cause welding distortion. The weight of the crossbar, that does not benefit from the longitudinal rigidity of the panels has an effect disadvantageous. The division of the skeleton, for example, when driving construction on windows and doors in the car body system. For the profile requires an alloy with a special tendency to weld Lich. The skeleton also causes jumps in stiffness, which is unun permanent secondary stress on the cover plates, while the Profiles form undesirable thermal bridges.
Der Erfindung liegt die Aufgabe zugrunde, gegeneinander stoßende Sand wichplatten direkt so miteinander zu verbinden, daß unter Vermeidung von bisher verwendeten zwischengeschalteten Profilen eine ebene oder zumin dest nahezu ebene Fläche entsteht und die Sandwichplattenverbindung einen gleichmäßigen Kraftfluß ermöglicht.The invention has for its object, abutting sand wichplatten to connect directly so that avoiding previously used intermediate profiles a flat or at least least flat surface and the sandwich panel connection enables an even flow of force.
Diese Aufgabe wird gemäß dem Kennzeichen des Anspruchs 1 gelöst. Die Unteransprüche beziehen sich auf weitere vorteilhafte Ausgestaltungen der Erfindung. This object is achieved in accordance with the characterizing part of claim 1. The Subclaims relate to further advantageous configurations the invention.
Die Sandwichplatten sind in vorteilhafter Weise so gestaltet, daß sowohl eine Deckschicht mit dem Kern der einen Platte als auch der Kern mit der gegenüberliegenden Deckschicht der anderen Platte je eine Stufe bilden, so daß das überstehende Ende der jeweils angrenzenden Sandwichplatte genau hineinpaßt und auf diese Weise alle drei Bauteile lückenlos miteinander verklebt werden können.The sandwich panels are advantageously designed so that both a top layer with the core of one plate as well as the core with the form the opposite top layer of the other plate, so that the protruding end of the adjacent sandwich plate fits exactly and in this way all three components without gaps can be glued together.
Zur überlappenden Kraftflußübertragung ist vorteilhaft jeweils am freien Kernende ein Streifen oder ein Winkelprofil eingeklebt. Winkelprofile sind insbesondere bei geraden Verbindungsstößen von Vorteil. Da die Winkelprofile den Kern entgegen der Montagerichtung umgreifen, wird hierdurch eine formschlüssige Verbindung gegen Abschälen der Klebever bindung erzielt. Außerdem ist es aufgrund der erhöhten Steifigkeit des Winkelprofils möglich, Befestigungspunkte, z.B. durch Blindnietmuttern, in diesem Bereich vorzusehen.For overlapping power flow transmission is advantageous in each case on the free A strip or an angled profile glued into the end of the core. Angle profiles are particularly advantageous for straight connection joints. Since the Angle profiles encompass the core against the assembly direction hereby a positive connection against peeling of the adhesive bond achieved. It is also due to the increased rigidity of the Angle profile possible, attachment points, e.g. through blind rivet nuts, to be provided in this area.
Durch wechselseitiges Kröpfen der Deckschichten kann der Kraftfluß vorteilhaft flächenbündig und einschnittig übertragen werden. Bei dünnen Deckschichten ist auch eine gerade Blechform möglich, wobei dann die Verbindung nicht ganz eben ist.By alternately cranking the outer layers, the flow of force can are advantageously transferred flush and one-cut. With thin Cover layers are also possible in a straight sheet form, in which case the Connection is not quite level.
In vorteilhafter Ausgestaltung der Erfindung sind die Deckschichten diagonal gegeneinander versetzt. Hierdurch ist es möglich, eine in Länge und Breite "unendliche" Platte zusammenzusetzen. Dazu werden die Deck bleche sowohl längs als auch quer versetzt auf den Kern geklebt. Damit ist ein gleichmäßiger Kraftfluß in beiden Ebenen gegeben.In an advantageous embodiment of the invention, the cover layers are diagonally offset from each other. This makes it possible to have one in length and width to put together "infinite" plate. To do this, the deck sheets glued to the core both longitudinally and transversely. In order to there is an even flow of force in both planes.
Da die Sandwichplatten direkt aneinandergesetzt werden und nicht ein Gerippe aus Profilen die Teilung bestimmt, können die Bleche oder das Kernmaterial in ihren lagerhaltigen Abmessungen ohne Verschnitt verwen det werden.Because the sandwich panels are put directly together and not one The structure of the frame determines the division, the sheets or that Use core material in its stocked dimensions without waste be det.
