Description

Die Erfindung betrifft einen aus Blechen zusammengesetzten Stahlträger, der als Bewehrung dient zur Herstellung von Stahlbeton-Deckenbalken, -Deckenrippen o. dgl. Unter Verwcrtdung derartiger Stahlträger können Decken ohne Verschalung hergestellt werden.The invention relates to a steel beam composed of sheet metal, which serves as reinforcement for the production of reinforced concrete ceiling beams and ceiling ribs or the like. With such steel girders ceilings can be ceilings without cladding getting produced.

Das Neue besteht in einem im Grundriß wellen- oder mäanderförmig verlaufenden gelochten Steg. Die Einbuchtungen werden zu beiden Seiten am oberen Ende des Steges durch zwei Schienen überbrückt. Der Stahlträger ist außerdem mit zwei Winkelschienen ausgeführt, die mit nach oben offenem Profil zu beiden Seiten am unteren Ende eines Steges befestigt sind und dabei durchlaufend die Einbuchtungen des Steges überbrücken. Die Ränder der Steglöcher sind teils nach der einen und teils nach der anderen Seite ausgebogen.The novelty consists in a plan that is undulating or meandering perforated bridge. The indentations are on both sides at the top of the web bridged by two rails. The steel beam is also equipped with two angle rails executed with the upwardly open profile on both sides at the lower end of a Web are attached and thereby continuously bridge the indentations of the web. The edges of the pier holes are partly on one side and partly on the other curved.

In der Zeichnung ist eine beispielsweise Ausführungsform veranschaulicht.An example embodiment is illustrated in the drawing.

Fig. i zeigt eine Seitenansicht, Fig. 2 eine Draufsicht; Fig. 3 zeigt einen Querschnitt in ungefähr natürlicher Größe, Fig. 4 ein Konstruktionsteil.FIG. 1 shows a side view, FIG. 2 shows a plan view; Fig. 3 shows a cross-section in approximately natural size, FIG. 4 a structural part.

Der Blechstreifen i ist zur Verstärkung, wie Fig. 2 veranschaulicht, mäanderförmig gebogen. Diese Einbuchtungen werden oben zu beiden Seiten von einer Längsschiene 2 überbrückt, desgleichen unten von einer Schiene 3. Der freie Schenkel 4 der unteren Winkelschiene 3 ist mit einer Lochung 5 versehen. Der Blechstreifen i hat Lochungen 6, wobei die Lochränder 7 dieser Lochungen teils nach der einen, teils nach der anderen Seite, wie aus Fig. 2 und 4 ersichtlich, ausgebogen sind. Diese Lochrandausbiegungen bilden warzenähnliche Vorsprünge zur Förderung einer innigen Verbindung mit dem Beton. Die vorgesehenen Lochungen 6, 5 erleichtern die vollständige Umhüllung des Stahlträgers mit Beton und fördern in Verbindung mit den Lochrandausbiegungen 7, die warzenähnliche Vorsprünge bilden, die innige Verbindung zwischen Stahl und Beton.The sheet metal strip i is for reinforcement, as Fig. 2 illustrates, meandering curved. These indentations are at the top on either side of one Longitudinal rail 2 bridged, likewise below by a rail 3. The free leg 4 of the lower angle rail 3 is provided with a perforation 5. The sheet metal strip i has holes 6, the hole edges 7 of these holes partly after the one, partly to the other side, as can be seen from FIGS. 2 and 4, are bent out. These Lochrandausbiegungen form wart-like projections to promote a intimate connection with the concrete. The provided holes 6, 5 facilitate the complete encasing of the steel girder with concrete and conveying in connection with the hole edge bends 7, which form wart-like projections, the intimate connection between steel and concrete.

Die De--kensteine erhalten ihre Auflage auf dem freien Winkelschenkel 4. Die Form der Deckensteine ist dieser Schenkelform anzupassen.The paving stones are placed on the free angle leg 4. The shape of the ceiling stones is to be adapted to this leg shape.
