Patentansprüche:Patent claims: 1; Warm- oder kaltgewalzter Stahlträger mit I-Querschnitt, dessen Obergurt gewellt ist, dadurch gekennzeichnet, daß die oberen Flanschränder unter Überschreitung der Elastizitätsgrenze wellenartig verformt sind und daß dadurch eine Druckspannung im unteren Flansch . (2) und eine negative Durchbiegung des Trägers erzeugt ist, wobei die Wellung zum Trägersteg (5) hin abnimmt, so daß der mittlere Teil des oberen Flansches (3) eben bleibt. t 1; Hot-rolled or cold-rolled steel girder with an I-shaped cross-section, the upper flange of which is corrugated, characterized in that the upper flange edges are deformed in a wave-like manner, exceeding the elastic limit, and that this results in a compressive stress in the lower flange. (2) and a negative deflection of the carrier is produced, the corrugation decreasing towards the carrier web (5) so that the middle part of the upper flange (3) remains flat. t 2. Träger nach Anspruch 1, dadurch gekennzeichnet, daß der untere Trägerflansch (2) im Querschnitt etwa doppelt so groß ist wie der obere.2. Carrier according to claim 1, characterized in that the lower carrier flange (2) in the Cross-section is about twice as large as the upper one. 3. Träger nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß er aus zwei verschweißten kaltgewalzten U-Profilen (6,7) besteht.3. Carrier according to claim 1 or 2, characterized in that it is welded from two cold-rolled U-profiles (6.7).
