Den gewalzten breitflanschigen 1 rägern wird in immer steigerndem Maße Be; ,chtung zugewendet. Ganz besondere Bea :htung verdienen die breitflans'chigen Träger rr it Flanschen gleichbleibender Stärke, also ohne j< de Neigung. Bekanntlich entstehen beim Wal sen von T-Trägern an den Übergangsstelle ι zwischen Steg und Flansch beträchtliche ί pannungen, die aus walztechnischen Gründen gering ausfallen, wenn die innere Flanschse te sich mit einer möglichst großen Neigung £ η den Steg ansetzt. Bei breitflanschigen Trägern mit Flanschen gleichbleibender Stärk) entstehen daher zwischen Steg und Flansch beim WaIzprozeß erhebliche Spannungen, ι lie bei der späteren Verwendung der Träger häufig unliebsame Erscheinungen im Gef ilge haben. Da nun die breitflanschigen Träger r lit neigungslosen Flanscheninnenseiten — r< in parallelflanschige Träger — infolge der m; nnigfaltigen Vorteile, die sie gegenüber den bre tflanschigen Trägern mit geneigten Flansche linnenseiten bieten, vielfach bevorzugt werden, so erscheint es von besonderem Wert, daß die 1 eim Walzen derselben zwischen Steg und I lansch auftretenden Spannungen möglichst lerabgesetzt werden.The rolled wide-flanged 1 girders are increasingly being used; , attention turned to. The wide-flanged beams with flanges of constant thickness, i.e. without any inclination, deserve special attention. It is known that when T-beams are whaled at the transition point ι between the web and the flange, considerable tensions occur which, for reasons of rolling technology, turn out to be low when the inner flange se attaches to the web with the greatest possible inclination. Therefore, in breitflanschigen carriers consistent with flanges starch) are formed between the web and flange at WaIzprozeß considerable stresses, ι the carrier lie in the later use often unpleasant phenomena in Found have Ilge. Since now the wide-flanged girders r lit inclination-free inner flanges - r <in parallel-flanged girders - as a result of the m; If the manifold advantages they offer over the wide-flange girders with inclined flanges on the inside are often preferred, it seems of particular value that the stresses that occur between the web and flange are reduced as much as possible when rolling them.
Gegenstand der Erfindung ist ein breitflanschiger Träger, der alle Vorz ige der bereits bekannten breitflanschigen Träger mit neigungslosen Flanscheninnenseitei besitzt, jedoch infolge seiner besonderen (luerschnittsform die beim Walzen dieser ar den Übergangsstellen zwischen Flansch ui d Steg auftretenden Spannungen nicht erlei< .et.The subject of the invention is a wide-flanged carrier that has all the advantages of the already known wide-flanged carrier with inclination-free Flanscheninnenseitei has, however due to its special (luschnittsform) the transition points when rolling this ar No stresses occurring between the flange and the web .et.

Auf der Zeichnung ist beispielsweise ein gemäß der Erfindung gestalteter Träger von I-förmigem Querschnitt dargestellt.In the drawing, for example, a carrier designed according to the invention is shown I-shaped cross-section shown.
Er besteht aus dem Steg α und den breiten Flanschen b. Die inneren Flanschkanten verlaufen nicht auf ihrer ganzen Länge parallel zu den äußeren Flanschkanten, sondern besitzen auf einer Strecke c eine bestimmte Neigung gegenüber den äußeren Flanschkanten. Neben den oben erwähnten Vorteilen wird hierdurch eine wesentliche Querschnittsver-Stärkung gerade an der Stelle erzielt, die ihrer auch aus statischen Gründen, namentlich im Hinblick auf die Anstrengung in der Flanschwurzel und die Übertragung der Scherspannungen bedarf. .It consists of the web α and the wide flanges b. The inner flange edges do not run parallel to the outer flange edges over their entire length, but have a certain inclination with respect to the outer flange edges over a distance c. In addition to the advantages mentioned above, this achieves a significant strengthening of the cross-section precisely at the point that also requires it for static reasons, namely with regard to the strain in the flange root and the transmission of shear stresses. .
Der vergrößerte Querschnitt an der Übergangsstelle zwischen Steg und Flansch sichert in diesem Sinne den inneren Zusammenhang des Profils und dient zur einwandfreien Überleitung von Spannungen aus den Flanschen zum Steg und umgekehrt. Als Übergang zwischen der eingelegten Schräge und dem Steg ist die übliche Abrundung beibehalten.The enlarged cross-section at the transition point between the web and flange secures In this sense, the inner context of the profile and serves for a perfect transition of stresses from the flanges to the web and vice versa. As a transition between the inserted slope and the The bridge has retained the usual rounding.
Als Maß für die Länge der Strecke c, auf die sich die Neigung erstreckt, kann ungefähr 1/7,5—1/8 der Gesamtflanschbreite und als Maß für die Neigung das SteigungsverhältnisApproximately 1/7.5-1 / 8 of the total flange width can be used as a measure of the length of the path c over which the inclination extends, and the gradient ratio can be used as a measure of the inclination
