Description
Zur schalungsfreien Herstellung von Stahlbetonrippendecken aus Fertigbalken mit zwischenliegenden Decksteinen werden an Stelle von Retonfertigbalken auch Metallträger verwendet, die in die Rippen einbetoniert werden. Bei Verwendung von Vollivandträgern ergibt sich der Nachteil, daß die sowieso verhältnismäßig dünnen Betonrippen durch den Trägersteg in zwei Hälften geteilt «erden, deren Zusammenwirken fraglich ist.For the production of reinforced concrete rib ceilings from prefabricated beams without formwork with capstones in between, metal girders are also used instead of prefabricated concrete beams used, which are concreted into the ribs. When using solid veneer beams there is the disadvantage that the anyway relatively thin concrete ribs through the support bar divided into two halves «earth the interaction of which is questionable.
Dem kann man nach vorstehender Erfindung begegnen, indem die Stege mit Löchern von beliebiger Größe und beliebigem Querschnitt versehen werden, durch welche hindurch der Beton der beiden Rippenhälften verbunden ist, oder man kann den Trägersteg mit aufgewalzten oder aufgepreßten Erhöhungen bzw. Vertiefungen versehen, durch welche die beiden Rippenhälften gewissermaßen miteinander verdübelt werden. Zugleich wird durch vorbeschriebene Maßnahmen eine außerordentlich gute Haftung des Betons an den Trägern erzielt und damit eine ausgezeichnete Verbundwirkung erreicht.This can be countered according to the above invention by the webs be provided with holes of any size and any cross-section, through through which the concrete of the two rib halves is connected, or one can provide the carrier web with rolled-on or pressed-on elevations or depressions, through which the two halves of the rib are to a certain extent pegged together. At the same time, the measures described above ensure extremely good adhesion of the concrete on the girders and thus achieves an excellent bond effect.
Der Gegenstand der Erfindung ist in Abb. i bis 4 dargestellt. Die Stahlbetonrippendecken können druckfeste Deckensteine c, wie in Abb. i und 4, oder Deckenfüllsteine i mit darüber betonierter Betondruckschicht k, wie in Abb. 2 und 3, erhalten. Die Träger können gewalzte Träger a oder durch Nietung oder Schweißung hergestellte Blechträger i sein. Bei dem Beispiel in Abb. i sind dem Stegblech Warzen d bzw. Riffeln e aufgewalzt. Bei dem Beispiel in Abb.2 sind dem Stegblech Buckel f bzw. Waffeln ä eingepreßt. Als weiteres Beispiel dieser Abbildung sind durchgehende oder begrenzte Wellen h des Stegblechs dargestellt. In Beispie13 und 4 sind Beispiele für durchbrochene Stegbleche gezeigt. In Abb.3 sind runde, nt, und längliche Löchern dargestellt. Da die dünnen Stegblechränder auf den Beton eine meißelartige Wirkung haben, werden die Lochränder durch Bördelung o bzw. durch aufgenietete oder aufgeschweißte Randverstärkungen p, wie in Abb. ¢, verbreitert.The subject of the invention is shown in Figs. the Reinforced concrete rib ceilings can be pressure-resistant ceiling stones c, as in Fig. I and 4, or Ceiling filler blocks i with concrete pressure layer k concreted over it, as in Fig. 2 and 3, received. The beams can be rolled beams or by riveting or welding be manufactured sheet metal carrier i. In the example in Fig. I there are lugs on the web plate d or corrugations e rolled on. In the example in Fig. 2 there are bumps on the web plate f or wafers ä pressed in. As another example of this figure are continuous or limited waves h of the web plate shown. Examples 13 and 4 are examples shown for openwork web plates. In Fig 3 are round, nt, and oblong holes shown. Because the thin web sheet edges have a chisel-like effect on the concrete the edges of the holes are flanged or riveted or welded on Edge reinforcements p, as in Fig. ¢, broadened.
