Description

Die Erfindung betrifft einen Profilträger aus Metall stenwänden 3, 4 und 5, 6 verbunden ist. Bei dem darmit einem geraden oder durch Verformungen ver- 40 gestellten Ausführungsbeispiel liegt der Steg 9 mit steiften Steg und mit zwei mit dem Steg verschweiß- seinen Längskanten zwischen den einander zugeten Trägergurten, von denen jeder Trägergurt zwei wandten Hohlkastenwänden 3 bis 6 der Trägergurte beidseitig des Steges durch Umfalzen gebildete Hohl- A, B an der Innenseite der jeweiligen Gurtaußenkästen aufweist, die durch die Gurtaußenwand mit- wand 7, 8 an.The invention relates to a profile beam made of metal stenwwall 3, 4 and 5, 6 is connected. In the exemplary embodiment that is straight or displaced by deformations, the web 9 with a rigid web and two longitudinal edges welded to the web lies between the carrier belts that are connected to one another, of which each carrier belt has two facing hollow box walls 3 to 6 of the carrier belts on both sides The web has hollow A, B formed by crimping on the inside of the respective outer belt boxes, which wall 7, 8 through the outer belt wall.
