Description

Zum Herstellen von insbesondere im Rüttelpreßverfahren zu fertigenden bewehrten Betonrohren geeigneter Bewehrungskorb Es ist ein Bewehrungskorb aus kreisförmigen, geschlossenen Bewehrungsringen und einer Diagonalbewehrung, die mit den Längsstäben verbunden sind, zum Herstellen von insbesondere im Rüttelpreßverfahren zu fertigenden bewehrten Betonrohren bekannt. Nachteilig war hierbei, daß beim Rüttelpreßverfahren zwangläufig auf die Spirale und auf die Verteiler ein Druck ausgeübt wurde, so daß beim Entschalen sich die Verteilerstäbe in die Ausgangsstellung zurückreckten und die Spirale mitbewegten, wodurch im frischen Beton Risse entstanden, die das Betonrohr unbrauchbar machten. Zur Beseitigung dieser Nachteile wird erfindungsgemäß vorgeschlagen, daß die Längsstäbe im oberen Drittel geteilt und miteinander über angeknüpfte Verbindungsstäbe längsnachgiebig verbunden sind. Hierdurch können beim Entschalen die Verteilerstäbe und auch die Ringe nur in geringem Umfang in die Ausgangsstellung zurücktreten, so daß die gefürchtete Rißbildung vermieden wird.For the manufacture of, in particular, those to be manufactured using the vibration press process reinforced concrete pipes suitable reinforcement cage It is a reinforcement cage made of circular, closed reinforcement rings and a diagonal reinforcement with the longitudinal bars are connected, for the production of to be manufactured in particular in the Vüttelpreßverfahren reinforced concrete pipes known. The disadvantage here was that the Vüttelpreßverfahren inevitably a pressure was exerted on the spiral and on the manifold, so that When removing the formwork, the distributor rods retracted into the starting position and the spiral moved with it, creating cracks in the fresh concrete, which the concrete pipe rendered useless. To eliminate these disadvantages, it is proposed according to the invention that that the longitudinal bars are divided in the upper third and connected to each other via linked connecting bars are connected in a longitudinally flexible manner. This allows the distributor rods and also the rings only move back to their original position to a small extent, so that the feared cracking is avoided.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigt F i g. 1 den Drahtkorb und die Bewehrungsringe der Obermuffe und F i g. 2 die Draufsicht zu F i g. 1.In the drawing, the invention is illustrated, for example, namely, FIG. 1 the wire basket and the reinforcement rings of the upper sleeve and F i g. 2 shows the top view of FIG. 1.

Der Bewehrungskorb wird durch Ringe 1 gebildet, die an ihrer Stoßstelle miteinander verschweißt sind, und durch längsverlaufende Verteilerstäbe 2, an denen die Ringe angeknüpft sind. Die Verteilerstäbe 2 enden etwa im oberen Drittel des herzustellenden Betonrohres. An die Enden wird ein etwas dünneres Zwischenstück 3 angeknüpft, an das am anderen Ende kurze Verteilerstäbe 4 mit den Ringen 1 gleichfalls angeknüpft sind. Auf den Verteilerstäben 2 und 4 sitzen als Abstandhalter in bekannter Weise frei drehbare Scheiben 5 aus Beton, Kunststoff od. dgl. und am unteren Ende der Verteilerstäbe 2 gleichfalls frei drehbare, stärkere Scheiben 6, wobei die Verteilerstäbe nur zum Teil in diese eingreifen. Mit 7 sind zwei Diagonalstreben bezeichnet, die an mehreren Stellen mit den Verteilerstäben 2 und 4 und den Ringen 1 durch Anknüpfen verbunden sind.The reinforcement cage is formed by rings 1, which are welded to one another at their joint, and by longitudinal distributor bars 2 to which the rings are linked. The distribution bars 2 end approximately in the upper third of the concrete pipe to be produced. A somewhat thinner intermediate piece 3 is linked to the ends, to which short distribution rods 4 with the rings 1 are also linked at the other end. On the distributor rods 2 and 4, freely rotatable disks 5 made of concrete, plastic or the like sit as spacers in a known manner, and at the lower end of the distributor rods 2 likewise freely rotatable, stronger disks 6, the distributor rods only partially engaging them. With 7 two diagonal struts are referred to, which are connected at several points with the distributor rods 2 and 4 and the rings 1 by tying.

Im oberen Muffenteil des herzustellenden, gestrichelt gezeichneten Betonrohres werden Ringe 8 eingelegt, die durch winkelförmig gebogene Drähte 9 verbunden sind, so daß auch eine Bewehrung in diesem Teil des Betonrohres gegeben ist.In the upper part of the socket to be produced, shown in dashed lines Concrete pipe rings 8 are inserted, which are connected by wires 9 bent at an angle are, so that there is also reinforcement in this part of the concrete pipe.
