Abstract
Description
Die Erfindung betrifft ein Knotenelement gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a node element according to the generic term of claim 1.
Rahmenkonstruktionen mit einer räumlichen Gitterstruktur, die im Enzelnen aus Hohlprofilen besteht, welche über Knotenelemente verbunden sind, sind an sich bekannt. Dabei werden häufig Aluminiumguss-Knotenelemente verwendet. Die Fertigung der Knoten als Gussteile ist aufwendig, da kein störender Grad vorhanden sein darf und Bauteiländerungen hohe Investitionen fordern.Frame structures with a spatial lattice structure, which in the individual consists of hollow profiles, which over node elements connected are known per se. Cast aluminum node elements are often used used. The production of the knots as castings is complex, since no annoying Degrees may exist and component changes high investments demand.
Um diesen Nachteil zu vermeiden,wird
in der
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Knotenelement zur Verbindung von Hohlprofilen für eine Rahmenkonstruktion anzugeben, das einfach und kostengünstig bereitgestellt werden kann.Against this background, the Invention, the object of a node element for connection of hollow profiles for to provide a frame structure that is provided simply and inexpensively can be.
Diese Aufgabe wird gelöst mit einem Knotenelement gemäß den Merkmalen des Patentanspruchs 1. Die Unteransprüche betreffen besonders zweckmäßige Weiterbildungen der Erfindung.This problem is solved with a Node element according to the characteristics of claim 1. The subclaims relate to particularly useful further training the invention.
Erfindungsgemäß ist also ein Knotenelement zur Verbindung von mehreren Hohlprofilen für eine Rahmenkonstruktion vorgesehen, welches aus einem Strangpressprofil besteht. Dabei wird ein Teilstück von dem Strangpressprofil abgelängt, dessen Länge der maximalen Länge des herzustellenden Knotenelementes in Längsrichtung des Profils entspricht. Anschließend werden Bereiche des abgelängten Pressprofils ausgeschnitten, um das endgültige Knotenelement zu erhalten. Obwohl bei dem Herausschneiden ein Verschnitt entstehen kann, ist diese Herstellungsweise des Knotenelementes deutlich preiswerter als Anwendung eines Gießverfahrens oder einer Umformung, beispielsweise Innenhochdruckumformung.According to the invention is therefore a node element for Connection of several hollow profiles provided for a frame construction, which consists of an extruded profile. A section of the Extruded profile cut to length, its length the maximum length corresponds to the node element to be produced in the longitudinal direction of the profile. Subsequently are areas of the cut to length Cut the press profile to obtain the final knot element. Although there is a waste when cutting out, is this way of manufacturing the node element significantly cheaper as application of a casting process or forming, for example hydroforming.
Bevorzugt weist das Strangpressprofil mehrere Kammern auf, um so unterschiedlichen Anforderungen an das Knotenelement gerecht zu werden. In Abhängigkeit von der Form und Anzahl der Kammern können Knotenelemente hergestellt werden, die mehrere Endbereiche aufweisen, die in unterschiedliche Raumrichtungen weisen.The extruded profile preferably has several chambers to meet different demands on the To meet node element. Depending on the shape and number of the chambers can Node elements are produced which have several end regions, that point in different spatial directions.
In vorteilhafter Weise weist das Knotenelement zumindest abschnittsweise Vorsprünge auf, welche bei zusammengefügter Verbindung auf die gegenüberliegende Fläche des Hohlprofils unter Vorspannung einwirken. Die Abmessungen der Vorsprünge sind dabei so dimensioniert, dass stets senkrecht zur Einschubrichtung eine Vorspannung erzeugt wird. Durch die Vorspannung werden das Knotenelement und die Hohlprofile relativ zueinander fixiert, so dass ohne zusätzliche Einrichtungen gegebenenfalls erforderliche weitere Verbindungsmaßnahmen durchgeführt werden können.Advantageously, this Node element at least in sections on projections, which when the connection is joined to the opposite area of the hollow profile under pre-tension. The dimensions of the projections are dimensioned so that they are always perpendicular to the direction of insertion a bias is generated. Due to the preload, the node element and the hollow profiles fixed relative to each other, so that without additional Facilities may require additional liaison measures carried out can be.
Besonders vorteilhaft ist, wenn das Knotenelement im Verbindungsbereich zumindest abschnittsweise konisch ausgeführt ist. Durch die konische Ausführung ist ein leichteres Einführen möglich, eine Zentrierung gegeben und eine höhere Haltekraft möglich.It is particularly advantageous if that Node element in the connection area, at least in sections, conical accomplished is. Due to the conical design is an easier introduction possible, given a centering and a higher holding force possible.
Zur Verbindung des Knotenelementes mit Hohlprofilen hat es sich als vorteilhaft erwiesen, wenn das Knotenelemente an seinen Enden clipsartige Rastelemente aufweist. Dadurch ist eine kraftschlüssige Verbindung zwischen Knotenelement und den Hohlprofilen möglich. Bevorzugt weist das Knotenelement an seinem Endbereich stegförmige Rastelemente auf.For connecting the node element with hollow profiles, it has proven to be advantageous if that Knot elements has clip-like locking elements at its ends. This is a non-positive Connection between node element and the hollow profiles possible. Prefers the node element has web-shaped locking elements at its end region on.
Die Hohlprofile weisen bevorzugt entsprechende Ausnehmungen auf, in die die Rastelemente des Knotenelementes einrasten. Hierdurch wird in einfacher Weise die Verbindung gesichert.The hollow profiles preferably have corresponding recesses into which the locking elements of the node element engage. In this way, the connection is secured in a simple manner.
Die endgültige Verbindung zwischen Knotenelement und Hohlprofilen kann in an sich bekannter Weise durch Schweißen, Kleben, Schrauben oder Nieten erfolgen. Diese ist jedoch auch erreichbar, wenn Steckverbindungen als selbstsichernde Presspassungen ausgeführt werden.The final connection between the node element and hollow profiles can be welded, glued, Screws or rivets. However, this can also be reached if Plug connections are designed as self-locking press fits.
