Description
Die Erfindung betrifft dieAusbildung von Betonformstücken, insbesondere von Betonrohren für Kanalisationen, Brunnenbau u. dgl., und die Verbindung solcher Formstücke bzw. Rohre. Bei bekannten Rohren der erwähnten Art besteht die Verbindung aus Falzen, die mit Zementmörtel ausgelegt und gegebenenfalls außen noch mit einer Wulst aus Zementmörtel umhüllt werden. Die bekannte Verbindungsart von Rohren ist nicht in der Lage, die infolge ungleichmäßiger Auflagerdrücke von Erdverschiebungen, Absackungen o. dgl. auftretenden Kräfte aufzunehmen, so daß sich die Rohre verschieben und die Verbindung zerreißt.The invention relates to the formation of concrete fittings, in particular of concrete pipes for sewer systems, well construction, etc., and the connection of such Fittings or pipes. In known pipes of the type mentioned, there is a connection from folds that are lined with cement mortar and, if necessary, with one on the outside Bead of cement mortar to be encased. The well-known connection type of pipes is unable to cope with the uneven bearing pressures caused by the displacement of the earth, Absorbs sagging o. The like. Forces occurring so that the pipes move and the connection breaks.
Demgegenüber besteht die Erfindung darin, daß Betonformstücke, insbesondere Betonrohre, mit einerLängsbewehrung und gegebenenfalls mit einer Querbewehrung versehen sind, die an ihren Enden Ösen, gezahnte Leisten oder Nutringe zur Aufnahme von Spannschlössern zum Aneinanderpressen der Formstücke bzw. Rohre aufweisen.In contrast, the invention consists in that concrete fittings, in particular Concrete pipes, provided with longitudinal reinforcement and, if necessary, with transverse reinforcement are that have eyelets, toothed strips or grooved rings at their ends to accommodate turnbuckles for pressing the fittings or pipes together.
Die Ösen, gezahnten Leisten, Nutringe o. dgl. stehen zweckmäßig über die Oberfläche der Formstücke bzw. der Rohre nicht vor, so daß die bisher benutzte Schalung für die Herstellung der Formstücke bzw. Betonrohre beibehalten werden kann.The eyelets, toothed strips, grooved rings or the like are expediently protruding the surface of the fittings or the pipes not before, so that the previously used Formwork for the production of the fittings or concrete pipes can be retained.
Bei einer Verbindung von Betonformstücken, insbesondere Betonrohren mit an den Enden der Bewehrung angebrachten gezahnten Leisten, sind die gezahnten Leisten zweier aneinanderstoßender Formstücke bzw. Betonrohre durch eine beide Leisten übergreifende Zahnstange überdeckt, die durch Sicherungsschrauben an den Leisten und gegebenenfalls an der Bewehrung gehalten ist.When connecting concrete fittings, especially concrete pipes with serrated strips attached to the ends of the reinforcement, the ones are serrated Strips of two adjoining fittings or concrete pipes through one of the two strips overlapping rack covered by locking screws on the bars and is held to the reinforcement if necessary.
Die Bewehrung kann auch zur Ermöglichung der Verwendung alter Formstücke bzw. Rohre auf der Außenseite des Formstückes oder der Betonrohre angeordnet sein.The reinforcement can also be used to enable the use of old fittings or pipes can be arranged on the outside of the fitting or the concrete pipes.
Durch die Anordnung von Spannschlössern gemäß der Erfindung entsteht durch die aneinandergereihten Formstücke ein durchlaufender Zuggurt, der ein Absinken oder Ausscheren einzelner Formstücke bzw. Rohrteile verhindert. Ferner ermöglicht das Anziehen der Spannschlösser eine vollkommene Dichtung der Stöße.The arrangement of turnbuckles according to the invention arises through the lined-up fittings a continuous tension belt that prevents a sinking or shearing of individual fittings or pipe parts is prevented. Also enables tightening the turnbuckles a perfect seal of the joints.
In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.Exemplary embodiments of the subject matter of the invention are shown in the drawing shown.
Abb. i bis 3 zeigen Längsschnitte durch gemäß der Erfindung ausgebildete Rohre und ihre Verbindungen, und Abb. 4 ist die Ansicht eines Stoßes von Betonrohren mit außenliegender Bewehrung und mit zwei verschiedenen Ausführungsformen des Spannschlosses.Figs. I to 3 show longitudinal sections through formed according to the invention Pipes and their connections, and Fig. 4 is a view of a joint of concrete pipes with external reinforcement and with two different versions of the turnbuckle.
Bei dein in Abb. i dargestellten Ausführungsbeispiel sind die Betonrohre
