Description
Träger mit auf dem Gurt aufgeschweißter Verstärkungslamelle Die Erfindung betrifft die Herstellung von geschweißten Trägern und insbesondere solchen, auf deren Gurtteil zur Verstärkung Platten, sogenannte Lamellen, aufgeschweißt sind.Beam with reinforcing lamella welded onto the belt The invention relates to the manufacture of welded beams and particularly those the belt part of which plates, so-called lamellae, are welded on for reinforcement.
Bei bisher bekannten Ausführungen solcher Träger hat sich gezeigt, daß Risse und Zerstörungen des Baustoffes zuerst an den Stellen der Gurte, an welchen die Endverschiveißungen der Lamellen ansetzen, eintreten. Dies ist daraus zu erklären, daß bei Belastung des Trägers ,an den Endverschweißungen der Lamellen .auf den Gurtteil eine Kerbwirkung ausgeübt wird, die sich der in der äußeren Trägerfaser naturgemäß. stärksten Beanspruchung, z. B. Zugspannung, überlagert und dadurch ;eine besonders hohe Beanspruchung des Baustoffes an der betreffenden Stelle hervorruft.In previously known designs of such carriers, it has been shown that that cracks and destruction of the building material first at the points of the belts, at which the end wear of the lamellas begin to occur. This can be explained by that when the carrier is loaded, at the end welds of the lamellas .on the belt part a notch effect is exerted which is inherent in the outer carrier fiber. heavy use, e.g. B. tensile stress, superimposed and thereby; one special causes high stress on the building material at the relevant point.
Diese Nachteile werden durch die Erfindung bei Trägern mit auf dem Gurt aufge-. schweißter Lamelle dadurch vermieden, daß der Gurt auf seiner Außenseite eine Einbuchtung aufweist und die Enden der Verstärkungslamellen nach der Trägerachse hin abgebogen und in der Einbuchtung des Gurtes verschweißt sind. Durch diese Ausgestaltung werden die Endverschweißungen der Lamellen aus der .äußeren Zone des Trägers in eine bei Belastung weniger hoch beanspruchte Zone verlegt, wo die an den Verschweißungen auftretenden Kerbwirkungen sich nicht so schädlich auswirken können.These disadvantages are by the invention in carriers with on the Strap on. welded lamella avoided that the belt on its outside has an indentation and the ends of the reinforcement lamellas according to the carrier axis are bent down and welded in the indentation of the belt. Through this design the end welds of the lamellas from the outer zone of the carrier in a zone that is less exposed to stress is laid where the welds occurring notch effects can not be as damaging.
Die Einbuchtungen für die Aufnahme der Lamellenenden bzw. deren Verschweißung können je .nach der Form des Trägers und der Lamelle verschieden sein. Es kÖnnen sowohl besondere Ausbuchtungen geschaffen wie auch solche an bekannten Trägerprofilen vorhandene benutzt werden.The indentations for receiving the lamella ends or their welding can be different depending on the shape of the carrier and the lamella. It can both special bulges created as well as those on known carrier profiles existing ones can be used.
In den Zeichnungen sind verschiedene Ausführungsbeispiele :dargestellt, und zwar zeigen: Abb. i, q., 6, 8 und io je eine Aufsicht auf die erfindungsgemäße Lamellenanordnung bei verschiedenen bekannten Trägerprofilen, Abb. 2 einen Längsschnitt gemäß Linie I I-1 I der Abb. i, Abb.3, 5, 7 und 9 Querschnitte, entsprechend den zugehörigen Aufsichten.Various exemplary embodiments are shown in the drawings: namely show: Fig. i, q., 6, 8 and io each a plan view of the invention Lamella arrangement in various known carrier profiles, Fig. 2 is a longitudinal section according to line I I-1 I of Fig. i, Fig.3, 5, 7 and 9 cross-sections, corresponding to the associated oversight.
Bei der in Abb. i und 2 dargestellten Ausführungsform ist auf dem Träger i die Lasche 2 mit ihrem Ende 3 in eine Ausbuchtung q. hereingezogen und dort verschweißt. Diese Endverschweißung 5 liegt unter der äußeren Trägerfaser.In the embodiment shown in Fig. I and 2 is on the Carrier i the flap 2 with its end 3 in a bulge q. drawn in and welded there. This end weld 5 lies under the outer carrier fiber.
Abb. 3 und q. zeigen in Aufsicht und Schnitt .einen Träger mit winkelförmig ausgebildetem Obergurt 6, bei dem die Verstärkungslasche 2 mit ihrem Ende 3 bis auf den Grund 7 des Winkelprofils 6 herabgezogen und dort verschwei.ßt ist.Fig. 3 and q. show in plan and section .a carrier with angled formed upper belt 6, in which the reinforcing flap 2 with its end 3 to is pulled down to the bottom 7 of the angle profile 6 and is welded there.
Die in Abb. 5 bis i o angeführten Ausführungsbeispiele zeigen die Anwendung des Erfindungsgedankens in Verbindung mit bekannten Trägerprofilen.The embodiments listed in Fig. 5 to i o show the Application of the inventive concept in connection with known carrier profiles.
