Die Erfindung bezieht sich auf einen Träger für Bauzwecke nach Patentanmeldung B 60421 V/37b.The invention relates to a support for building purposes according to patent application B 60421 V / 37b.

Das diesen Träger charakterisierende einteilige Blechprofil, welches die Bewehrung des Betonuntergurtes bildet, weist schräg zur Trägerebene verlaufende, über die ganze Trägerlänge durchgehende, die Betonleiste des Untergurtes verankernde Faltflanken auf. Die starken Umbüge und die verhältnismäßig hohen Faltflanken verursachen leicht ein Verziehen, Verdrehen oder innere Spannungen des Blechprofils bei seiner Herstellung im Walzverfahren. Diese unerwünschte Verformung kann nur durch Walzwerkzeuge von außergewöhnlicher Genauigkeit5 beispielsweise geschliffene Walzen, vermieden werden. Solche Werkzeuge sind jedoch mit hohen Kosten belastet. The one-piece sheet metal profile characterizing this girder, which forms the reinforcement of the concrete lower chord, has folded flanks which run obliquely to the girder plane and which extend over the entire length of the girder and anchor the concrete strip of the lower chord. The strong folds and the relatively high fold flanks easily cause warping, twisting or internal stresses in the sheet metal profile when it is manufactured using the rolling process. This undesirable deformation can only be avoided by using rolling tools of exceptional accuracy 5, for example, ground rollers. However, such tools have a high cost.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß mindestens ein Teil der Oberfläche des Blechprofils durch in Längsrichtung verlaufende Wellung, Rillung, Zahnung od. dgl. vergrößert ist.According to the invention, these disadvantages are avoided in that at least part of the surface of the sheet metal profile by corrugation, grooves, teeth or the like running in the longitudinal direction is.

Die Wellung, Rillung, Zahnung od. dgl. wird vorteilhaft bereits am ebenen Ausgangsmaterial vorgenommen, so daß bei der folgenden ProfiIgebung die Umbüge zwischen den horizontalen Profilstreifen und den schrägen Faltflanken durch die Wellung, Rillung, Zahnung od. dgl. eingeleitet und erleichtert werden. Die Wellung, Rillung, Zahnung od. dgl. bewirkt überdies, daß ein Verziehen, Verdrehen oder innere Spannungen des Blechprofils auch dann vermieden werden, wenn Walzwerkzeuge von übücher Genauigkeit Anwendung finden. Dies gilt sowohl für den Fall, daß das Blechprofil mit Wellen, Rillen od. dgl., die in der Längsrichtung des Profils verlaufen, über seine ganze Breite versehen ist, als auch für den Fall, daß die Wellung, Rillung, Zahnung od. dgl. lediglich auf die Umbüge bzw. die Anschlüsse der schrägen Faltflanken beschränkt ist.The corrugation, grooving, toothing or the like is advantageously already carried out on the flat starting material, so that in the following profile the folds between the horizontal profile strips and the inclined folding flanks by the corrugation, grooving, toothing od. The like. Introduced and facilitated. The corrugation, grooving, toothing or the like also causes warping, twisting or internal stresses of the sheet metal profile can also be avoided when rolling tools of high accuracy Find application. This applies both to the case that the sheet metal profile od with waves, grooves. Like. Which in the Run longitudinally of the profile, is provided over its entire width, as well as in the event that the Corrugation, grooving, toothing or the like only on the folds or the connections of the inclined folding flanks is limited.

Die Wellung, Rillung, Zahnung od. dgl. hat auch eine Materialvergütung zur Folge, wodurch das Blechprofil in der Lage ist, bei gleicher Wandstärke höhere Zugspannungen aufzunehmen. Endlich wird durch die Wellung, Rillung, Zahnung od. dgl. die für die Haftung zwischen dem Blechprofil und der Betonleiste des Untergurtes maßgebende Fläche wesentlich erhöht und damit die Verbundwirkung verbessert.The corrugation, grooving, toothing od. The like. Also has a material compensation as a result, whereby the sheet metal profile is able to absorb higher tensile stresses with the same wall thickness. Finally is through the corrugation, grooving, toothing od. The like. For the adhesion between the sheet metal profile and the concrete strip the decisive area of the lower chord is significantly increased and thus the composite effect is improved.

In der Zeichnung sind zwei Ausführungsbeispiele des erfindungsgemäßen Blechprofils in Querschnitten Träger für BauzweckeIn the drawing, two exemplary embodiments of the sheet metal profile according to the invention are shown in cross-sections Beams for building purposes

dargestellt. Das Blechprofil ist symmetrisch zur Trägermittelebene 1 angeordnet und weist bei den Ausführungsbeispielen drei schräge Faltflanken 2, 2', 2" auf. Diese Faltflanken sind erfindungsgemäß mit Wellen3 (Fig. 1), einer Rillung oder einer Zahnung 3 (Fig. 2) ausgestattet.shown. The sheet metal profile is arranged symmetrically to the carrier center plane 1 and in the exemplary embodiments has three inclined folding flanks 2, 2 ', 2 " . According to the invention, these folding flanks are equipped with corrugations 3 (FIG. 1), a grooving or a toothing 3 (FIG. 2) .

Diese Wellen oder Zahnungen 3 gestatten es, bei der Herstellung des Profils die Umbüge am Übergang zu den Faltflanken 2, 2', 2" besonders leicht und kostensparend zu erhalten. Aus der Zeichnung sind noch die Ansatzzonen der Streben 4 und beispielsweise mögliche Zulagestäbe 5 im Querschnitt ersichtlich. Der um das Profil vorzusehende Betonfuß ist mit bezeichnet. Die Faltflanken 2, 2', 2" laufen über die ganze Trägerlänge und etwa die ganze Trägerhöhe 7 des Blechprofils durch.These waves or sets of teeth 3 make it possible to receive in the production of the profile the Umbüge at the transition to the Faltflanken 2, 2 ', 2 "particularly easy and cost-saving. The shoulder zones of the struts 4 and, for example, possible additional bars 5 are still in from the drawing The concrete foot to be provided around the profile is denoted by. The folding flanks 2, 2 ', 2 " run over the entire length of the beam and approximately the entire height of the beam 7 of the sheet metal profile.

Die erfindungsgemäße Ausbildung ist auf die dargestellten und beschriebenen Beispiele nicht beschränkt. The design according to the invention is not limited to the examples shown and described.
