Description

Die vorliegende Erfindung betrifft ein Eckverbindungselement für Hohlprofile nach dem Oberbegriff des Anspruchs 1 oder 2 sowie ein Verfahren zur Herstellung dieses Verbindungselementes nach Anspruch 7.The present invention relates to a Eckverbindungselement for hollow sections according to the preamble of claim 1 or 2 and a method for producing this connecting element according to claim 7.

Derartige Eckverbinder finden im Fensterbau ihre Anwendung und verbinden die auf Gehrung geschnittenen Hohlprofile einer Rahmenkonstruktion, beispielsweise eines Fensters, wobei unterschiedliche Aussparungen in dem Verbindungselement vorgesehen sind, die zusammen mit dem Hohlprofil als Kanäle für einzufüllenden Kleber dienen. Außerdem sind in den Verbindungselementen geeignete Befestigungsvorrichtungen integriert mit denen der Zusammenbau des Rahmens schnell und belastbar durchgeführt werden kann.Such corner joints found in the window their application and connect the mitred hollow sections of a frame construction, such as a window, with different recesses are provided in the connecting element, which serve together with the hollow profile as channels for einzufüllenden glue. In addition, suitable fasteners are integrated in the fasteners with which the assembly of the frame can be performed quickly and resiliently.

Nach der erfolgten Montage der Rahmenkonstruktion wird Klebstoff durch eine Einfüllöffnung im Hohlprofil gepresst. Die Verteilung des Klebstoffes wird durch bereits im Querschnitt des Strangpressprofiles vorgesehene Aussparungen und Stege im Zusammenspiel mit einer Nut bewerkstelligt, wobei diese zusammen mit der Wand des Hohlprofiles Kanäle und Kammern bilden, die den Klebstoff an die Ober- und Unterseite des Eckverbinders und insbesondere auch entlang des, der Wetterseite zugewandten, Gehrungsspaltes des Hohlprofiles, transportiert.After the assembly of the frame construction adhesive is pressed through a filling opening in the hollow profile. The distribution of the adhesive is accomplished by already provided in the cross section of the extruded profile recesses and webs in conjunction with a groove, which together with the wall of the hollow profile channels and chambers form the adhesive to the top and bottom of the corner and in particular along of, facing the weather side, miter gap of the hollow profile, transported.

Wesentliches Merkmal der gewählten Geometrie ist ein Mittelsteg unterhalb der Gehrungsfuge des Hohlprofiles, der einerseits breit genug ist, um eine Nut aufzunehmen und sich andererseits zumindest an einer Stelle derart verjüngt, dass die Nut dort in die rechts und links davon liegenden Kammern hineinragt und mit der Einfüllöffnung im äußeren Hohlprofil verbindet.An essential feature of the selected geometry is a central web below the miter joint of the hollow profile, on the one hand wide enough to receive a groove and on the other hand tapers at least at one point such that the groove protrudes there into the right and left of these chambers and with the Filling opening in the outer hollow profile connects.

Die gewählte Geometrie in Verbindung mit der Nut ermöglicht das hier vorgestellte Fertigungsverfahren, bei dem in einem einzigen, kostengünstigen Arbeitsschritt durch die entlang der Gehrung verlaufende Nut sowohl ein Kanal erzeugt wird, durch den der Kleber von der Einfüllöffnung über die ganze Länge der Gehrungsfuge transportiert werden kann, und gleichzeitig die verschiedenen Kammern an der Ober- und Unterseite des Eckverbinders verbindet.The selected geometry in conjunction with the groove allows the manufacturing process presented here, in which in a single, cost-effective operation through the groove extending along the miter both a channel is generated, through which the adhesive from the filling opening over the entire length of the miter be transported can, and at the same time connects the different chambers at the top and bottom of the corner connector.

Ein Lösungsansatz wäre die Herstellung derartiger Verbindungselemente samt Klebekanal in einem Kokillen- oder Druckgussverfahren, was aber die Herstellungskosten des hier vorgestellten Verbindungselementes aus Strangpressprofil deutlich übersteigen würde.One approach would be the production of such fasteners together with glue channel in a mold or die casting process, but this would significantly exceed the manufacturing cost of the here presented connecting element of extruded profile.

Die Aufgabe der vorliegenden Erfindung liegt somit in der Bereitstellung eines geeigneten Eckverbinders, der eine schnelle und kostengünstige Verbindung von Hohlprofilen ermöglicht und gleichzeitig die Möglichkeit des nachträglichen Verklebens nach erfolgter Montage des Rahmens bietet, ein Auslaufen des Klebstoffes in die zur Materialersparnis angelegten Hohlkammern des Verbindungselementes und in in den Bereich hinter dem Verbindungselement verhindert und keine zusätzlichen Anbauteile oder Abdeckkörper benötigt.The object of the present invention is thus to provide a suitable corner connector, which allows a quick and cost-effective connection of hollow sections and at the same time offers the possibility of subsequent bonding after installation of the frame, leakage of the adhesive into the applied to save material hollow chambers of the connecting element and prevented in the area behind the connecting element and no additional attachments or cover body needed.

Diese Aufgabe wird durch einen Eckverbinder mit den kennzeichnenden Merkmalen des Anspruchs 1 oder 2 gelöst.This object is achieved by a corner connector with the characterizing features of claim 1 or 2.

Zur Material- und Gewichtseinsparung weisen die Eckverbinder üblicherweise eine fachwerkartige Struktur auf. Als Werkstoff werden im Strangpressverfahren hergestellte Aluminiumprofile verwendet. Aus diesen werden die Winkel in der gewünschten Höhe abgetrennt und in einem weiteren Arbeitsschritt mit einer oder zwei Nuten entlang des Mittelsteges versehen.To save material and weight, the corner connectors usually have a framework-like structure. The material used is extruded aluminum profiles. From these the angles are separated at the desired height and provided in a further step with one or two grooves along the central web.

Nach der Montage des Rahmens wird durch eine im Hohlprofil vorgesehene Einfüllöffnung Klebstoff eingepresst, der über die durch die Nut erzeugten Verbindungen den unter der Gehrungsfuge verlaufenden Klebekanal und die Kammern an den Flächen der inneren und äußeren Ecke des Verbinders auffüllt und abdichtet.After assembly of the frame is pressed by a provided in the hollow profile filler opening adhesive, which fills the joints generated by the groove extending under the miter joint adhesive channel and the chambers on the surfaces of the inner and outer corner of the connector and seals.

Das Verfahren zur Herstellung eines erfindungsgemäßen Eckverbinders nach Anspruch 1 oder 2, umfasst folgende Verfahrensschritte: Trennen eines Eckverbinderrohlings von einem stranggepressten Profil und Aufspannen mehrerer Eckverbinderrohlinge auf einem Bearbeitungtisch, auf dem alle Eckverbinder in einem einzigen Arbeitsschritt mit einem Zerspanungswerkzeug überfahren werden.The method for producing a corner connector according to the invention according to claim 1 or 2, comprises the following method steps: separating a Eckverbinderrohlings of an extruded profile and clamping a plurality Eckverbinder blanks on a machining table on which all corner connectors are run over in a single step with a cutting tool.
