Description
llohldielen mit röhrenförmigen Hohlräumen sind bekannt. Sie sind an beiden Enden offen und werden als frei aufliegende Träger berechnet.Llohl boards with tubular cavities are known. You are on open at both ends and are calculated as free-lying beams.
Die Erfindung besteht darin, daß die Hohlräume der Stahlbeton-Hohldielen an einem Ende oder an beiden Enden geschlossen sind und daß die Dielen an einem Ende oder an beiden Enden Rillen mit Verzahnungen zum Einlegen von oberen Bewehrungseisen aufweisen.The invention consists in that the cavities of the reinforced concrete hollow floorboards are closed at one or both ends and that the floorboards are closed at one end At the end or at both ends, grooves with serrations for inserting upper reinforcing bars exhibit.
Der Zweck der Erfindung ist, die Hohldielen als kontinuierliche Träger auszubilden, um hierdurch Material zu sparen und einen durchgehenden Zusammenhang der Deckenfelder herzustellen.The purpose of the invention is to use the hollow floorboards as a continuous beam train in order to save material and a continuous connection of the ceiling panels.
Abb. i zeigt eine geschlossene Hohldiele mit Rillen und macht die Verzahnungen der letzteren anschaulich; Alrb,. a stellt den Querschnitt einer Hohldiele dar mit unterer Zug- und oberer Transportbewehrung; Abb. 3 zeigt einen Längsschnitt durch die Rillen, und zwar zwei über einer Stütze aneinanderstoßende Dielen mit den Rillen R, den Verzahnungen h, der oberen Bewehrung über den Mittelstützen zur Aufnahme der negativen Momente, dem am Bau nach Verlegen der fertigen Hohldielen eingebrachten Beton C, den Hohlräumen H und .deren AbschluB ; Abb. 4 zeigt einen Längsschnitt durch die Stege der Hohldielen mit bis zu den Auflagern durchgehender unterer und oberer Bewehrung.Fig. I shows a closed hollow floorboard with grooves and makes the The interlocking of the latter vividly; Alrb ,. a represents the cross-section of a hollow board Dar with lower tensile and upper transport reinforcement; Fig. 3 shows a longitudinal section through the grooves, namely two planks butting against one another over a support the grooves R, the teeth h, the upper reinforcement over the central supports Recording of the negative moments in the building after laying the finished hollow planks poured concrete C, the cavities H and their closure; Fig. 4 shows one Longitudinal section through the webs of the hollow planks with a continuous section up to the supports lower and upper reinforcement.
Die Herstellung der Hohldielen erfolgt wie üblich durch Stahlrohre zwischen Seiten- und Kopfschalung. Hier jedoch werden an einem Ende mit einer ovalen Kappe verschlossene Röhren verwendet. Die Herstellung der geschlossenen Hohldielen erfolgt durch "Zurückziehung der Stahlrohre bis zu einem gewünschten Punkt, nachdem die Mitte der Hohldiele bereits festgestampft oder gerüttelt ist, damit die Rohre Führung haben und genau in der Achse der Hohlräume liegenbleiben. An dein zti schließenden Ende wird ein volles Blech vor die runden Öffnungen für die Rohre gestellt, eine Lehre für die Rillen eingelegt mild dann die Hohldiele an diesem Ende fertig gestampft oder gerüttelt. Hierdurch entsteht der in Abb.3 rechts dargestellte Zustand: eine am Ende geschlossene Hohldiele mit oder. wenn gewünscht, auch ohne Rillen. Durch vollständiges Herausziehen der Rohre, Einführen eines vorher gefertigten Pfropfens an eine gewünschte Stelle in den Hohlräumen, Auflegen der Lehre für die Rillen, Fertigstampfen oder Rütteln entsteht der "Zustand von Abb. 3 links: Eine am anderen Ende ebenfalls geschlossene Diele mit Rillen. Durch Herausziehen der Stahlrohre ohne Einführung des Pfropfens St entsteht eine an diesem Ende offene Hohldiele, falls so gewünscht.The hollow planks are made as usual using steel pipes between side and top formwork. Here, however, are at one end with an oval Cap-sealed tubes used. The production of the closed hollow planks is done by "withdrawing the steel pipes to a desired point after that." the middle of the hollow board is already tamped or jogged so that the pipes Have a guide and stay exactly in the axis of the cavities. To your zti closing At the end a full sheet is placed in front of the round openings for the pipes, one Gauge for the grooves inserted mildly then the hollow plank finished at this end or shaken. This creates the state shown in Fig. 3 on the right: a hollow board closed at the end with or. if desired, also without grooves. By Complete extraction of the pipes, insertion of a previously made plug at a desired location in the cavities, placing the gauge for the grooves, Finishing or shaking creates the "state of Fig. 3 left: One on the other The end of the board is also closed with grooves. By pulling out the steel pipes without the introduction of the plug St, a hollow board is created that is open at this end, if so desired.
