Description

Die Erfindung bezieht sich auf eine Befestigungsschiene für Trapezbleche in der Bautechnik, mit an den Schenkeln der am Querschnitt U-förmigen Schiene angebrachten Ankern. Solche Schienen sind z.B. aus DE-U-7 520 911 bekannt.The invention relates to a fastening rail for trapezoidal sheets in construction technology, with anchors attached to the legs of the cross-sectionally U-shaped rail. Such rails are e.g. known from DE-U-7 520 911.

Bei den bekannten Befestigungsschienen für Trapezbleche in der Bautechnik sind die Anker an den Schenkeln der im Querschnitt U-förmigen Schiene angeschweißt. Das Anschweißen ist aufwendig und teuer in der Herstellung.In the known fastening rails for trapezoidal sheets in construction technology, the anchors are welded to the legs of the rail which is U-shaped in cross section. The welding is complex and expensive to manufacture.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigungsschiene für Trapezbleche in der Bautechnik zu schaffen, deren Anker in herstellungstechnisch einfacher Weise mit den Schenkeln der Befestigungsschiene verbunden sind, wobei insbesondere eine sehr hohe Festigkeit der Verbindung angestrebt wird.The invention has for its object a mounting rail to create for trapezoidal sheets in construction, the anchors of which are connected in a technically simple manner to the legs of the fastening rail, in particular a very high strength of the connection being sought.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die aus Metallstreifen gebildeten Anker am Befestigungsende mit zwei sich in Längsrichtung des Metallstreifens erstreckenden, drei Laschen bildenden kurzen Einschnitten versehen sind, und daß die mittlere Lasche senkrecht zur Ebene des Metallstreifens abgebogen, durch den zugehörigen Längsschlitz des Schenkels der Schiene gesteckt und auf der anderen Seite des Schenkels umgebogen ist, so daß die beiden äußeren Laschen auf der einen Seite und mittleren Lasche auf der anderen Seite des Schenkels anliegen. Hierdurch wird eine in der Herstellung äußerst einfache Verbindung zwischen Anker und Befestigungsschiene geschaffen, welche eine große Festigkeit aufweist. Die Festigkeit kann insbesondere dadurch erheblich gesteigert werden, daß der mittlere Lappen in Richtung der beiden äußeren Lappen und parallel zu diesen abgebogen ist. Versuche haben gezeigt, daß diese Verbindungstechnik eine sehr hohe Verbindungsfestigkeit hat.To achieve this object, the invention provides that the anchors formed from metal strips at the fastening end are provided with two short incisions extending in the longitudinal direction of the metal strip, forming three tabs, and that the middle tab is bent perpendicular to the plane of the metal strip, through the associated longitudinal slot of the leg of the rail and is bent on the other side of the leg, so that the two outer tabs on one side and middle tab on the other side of the leg. This creates a connection between the anchor and the fastening rail which is extremely simple to manufacture and which has great strength. The strength can in particular be increased considerably in that the middle flap is bent in the direction of the two outer flaps and parallel to them. Tests have shown that this connection technique has a very high connection strength.

Die in der Fig. 1 in einer Perspektivdarstellung gezeigte Befestigungsschiene 1 ist im Querschnitt U-förmig und umfaßt eine flache Basis 10 sowie zwei rechtwinklig von dieser abstehende Schenkel 2. In die Randbereiche der Schenkel 2 sind an diametral gegenüberliegenden Stellen Längsschlitze 3 zur Befestigung von Ankern 4 eingebracht. Jeder Anker 4 besteht aus einem schmalen und flachen Metallstreifen 5, der vor der Montage mit der Befestigungsschiene 1 gemäß Fig. 2 U-förmig ausgeformt ist. Am Befestigungsende 6 sind senkrecht zur Stirnfläche des Metallstreifens 5 zwei parallele Einschnitte 7 eingebracht, welche das Befestigungsende 6 in eine innere Lasche 8 und zwei äußere Laschen 9 unterteilen, wie es in Fig. 1 dargestellt ist.The fastening rail 1 shown in FIG. 1 in a perspective view is U-shaped in cross-section and comprises a flat base 10 and two legs 2 protruding at right angles from it 4 introduced. Each anchor 4 consists of a narrow and flat metal strip 5, which is attached to the mounting rail prior to assembly 1 according to FIG. 2 is U-shaped. At the fastening end 6, two parallel incisions 7 are made perpendicular to the end face of the metal strip 5, which divide the fastening end 6 into an inner tab 8 and two outer tabs 9, as shown in FIG. 1.

Der vor der Montage gemäß Fig. 2 U-förmig gebogene Anker 4 trägt vor der Montage an seinem Befestigungsende 6 die parallel in der Ebene des gebogenen Metallstreifens 5 befindlichen beiden äußeren Laschen 9 und die hiervon rechtwinklig nach innen abgebogenen inneren Laschen 8. In diesem Zustand wird der Anker 4 über die darunter befindliche Befestigungsschiene 1 derart gebracht, daß die Längsschlitze 3 in den Schenkeln 2 der Befestigungsschiene 1 in eine Ebene mit den rechtwinklig abstehenden inneren Laschen 8 des Ankers 4 gelangen. Nun wird der Anker 4 gemäß Fig. 3 durch ein nicht näher dargestelltes Werkzeug verformt, wobei die inneren Laschen 8 durch die Längsschlitze 3 in den Schenkeln 2 in das Innere der Befestigungsschiene 1 eindringen, wobei die äußeren Laschen 9 auf der Außenseite der Schenkel 2 zur Anlage kommen. Anschließend werden die inneren Laschen 8 gemäß Fig. 4 nach innen abgebogen und zwar parallel zu den äußeren Laschen 9 in Richtung auf die Basis 10 der Befestigungsschiene 1. Der Anker 4 ist nunmehr mit sehr hoher Festigkeit mit der Befestigungsschiene 1 verbunden.The anchor 4 bent into a U shape prior to assembly according to FIG. 2 carries the two outer straps 9 located parallel in the plane of the bent metal strip 5 and the inner straps 8 bent from it at right angles inward at its fastening end 6 in this state the armature 4 is brought over the fastening rail 1 underneath in such a way that the longitudinal slots 3 in the legs 2 of the fastening rail 1 reach a plane with the inner tabs 8 of the armature 4 which protrude at right angles. 3 is deformed by a tool, not shown, the inner tabs 8 penetrate through the longitudinal slots 3 in the legs 2 into the interior of the fastening rail 1, the outer tabs 9 on the outside of the legs 2 for Plant come. The inner tabs 8 according to FIG. 4 are then bent inwards, namely parallel to the outer tabs 9 in the direction of the base 10 of the fastening rail 1. The armature 4 is now connected to the fastening rail 1 with very high strength.

In der in den Figuren 5 bis 7 dargestellten zweiten Ausführungsform der Verbindung zwischen Anker 4′ und Befestigungsschiene 1′ sind die inneren Laschen 8′ rechtwinklig nach außen abgebogen, wie es in Fig. 5 dargestellt ist, wobei die Befestigungsenden 6′ des Ankers 4′ von innen in die Längsschlitze 3′ der Schenkel 2′ der Befestigungsschiene 1′ eingreifen, wie es in Fig.6 dargestellt ist. Anschließend werden die inneren Laschen 8′ parallel zu den Schenkeln 2′ der Befestigungsschiene 1′ abgebogen und zwar in Richtung auf die Basis 10′ der Befestigungsschiene 1′. Auch hierdurch wird eine Verbindung zwischen Befestigungsschiene 1′ und Anker 4′ mit sehr hoher Festigkeit geschaffen, wobei die Form des von der Befestigungsschiene 1′ hervorstehenden Ankers 4 sich von der Form des Ankers 4 gemäß den Figuren 1 und 3,4 dadurch unterscheidet, daß der Anker 4′ als gerader Metallstreifen 5′ ausgebildet ist, der gegebenenfalls mit Durchbrüchen zur besseren Verbindung mit dem Betonbauteil versehen sein kann.In the second embodiment of the connection between anchor 4 'and fastening rail 1' shown in FIGS. 5 to 7, the inner tabs 8 'are bent outwards at a right angle, as shown in FIG. 5, the fastening ends 6' of the anchor 4 ' engage from the inside in the longitudinal slots 3 'of the leg 2' of the mounting rail 1 ', as shown in Fig.6. Then the inner tabs 8 'parallel to the legs 2 'of the mounting rail 1' bent in the direction of the base 10 'of the mounting rail 1'. This also creates a connection between the fastening rail 1 'and anchor 4' with very high strength, the shape of the armature 4 projecting from the fastening rail 1 'differing from the shape of the armature 4 according to FIGS. 1 and 3, 4 in that the anchor 4 'is formed as a straight metal strip 5', which can optionally be provided with openings for better connection to the concrete component.

In bekannter Weise werden die Befestigungsschienen 1, 1′ in ein Betonteil derart eingebettet, daß die Basis 10, 10′ bündig mit der Oberfläche des Betonbauteiles liegt, so daß durch die Befestigungsschiene 1,1′ hindurch Befestigungsschrauben geschraubt werden können. Im Innenraum der Befestigungsschiene 1,1′ befinden sich dann weiche Materialien, wie Holz oder Polystyrol, die ein Eindringen von Beton in den U-förmigen Innenraum der Befestigungsschiene 1,1′ verhindern.In a known manner, the fastening rails 1, 1 'are embedded in a concrete part such that the base 10, 10' lies flush with the surface of the concrete component, so that fastening screws can be screwed through the fastening rail 1, 1 '. In the interior of the mounting rail 1.1 'are then soft materials such as wood or polystyrene, which prevent the penetration of concrete into the U-shaped interior of the mounting rail 1.1'.
