Description

Die Erfindung betrifft ein rechteckförmiges Bauelement aus Beton mit einer rinnenförmigen Aussparung, die mit einer im Betonkörper verankerten Auskleidung aus Kunststoff versehen ist, zur Erstellung eines abgedichteten Rinnensystems mit Steckverbindung.The invention relates to a rectangular component made of concrete with a groove-shaped recess, which is provided with a plastic lining anchored in the concrete body, for creating a sealed channel system with a plug connection.

Bei derartigen Rinnensystemen werden im allgemeinen mehrere Bauelemente der vorgenannten Art aneinandergereiht, wobei die Aufgabe besteht, ein sicheres Abdichten des Systems, insbesondere zwischen den Verbindungsstellen der einzelnen Bauelemente, herzustellen. Hierzu sind schon verschiedene Vorschläge bekanntgeworden, die im allgemeinen darin bestehen, an den Verbindungsstellen zwischen den einzelnen Bauelementen Dichtungen einzusetzen. Die einzelnen Bauelemente mußten dabei mit Klammern oder Bügeln fest gegeneinander gepreßt werden, um eine gute Abdichtung zu erzielen.In such gutter systems, several components of the aforementioned type are generally strung together, the task being to produce a secure seal of the system, in particular between the connection points of the individual components. Various proposals have already become known for this, which generally consist in using seals at the connection points between the individual components. The individual components had to be pressed firmly against one another with clips or brackets in order to achieve a good seal.

Bei weiterhin bekanntgewordenen Rinnensystemen ist die rinnen-, vorzugsweise U-förmige Aussparung mit einer Kunststoffauskleidung versehen, die im Betonkörper verankert ist. Damit soll vermieden werden, daß Flüssigkeit in den Betonkörper eindringt.In channel systems that have become known, the Gutter, preferably U-shaped recess with a plastic lining that is anchored in the concrete body. This is to prevent liquid from entering the concrete body.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Bauelement der eingangs genannten Art zu schaffen, mit dem insbesondere an den Verbindungsstellen der Bauelemente untereinander ein vollständig abgedichtetes Rinnensystem bei einfacher Verlegung erreicht wird.The present invention has for its object to provide a component of the type mentioned, with which a completely sealed channel system is achieved with simple installation, in particular at the junctions between the components.

Die Aufgabe wird durch ein Bauelement der eingangs genannten Art gelöst, welches dadurch gekennzeichnet ist, daß an einem stirnseitigen Ende des Betonkörpers die Aussparung und die Kunststoffauskleidung als U-förmige Muffe mit einer, im Querschnitt gesehen, U-förmigen Nut zur Aufnahme einer Dichtung ausgebildet sind, und daß vom anderen stirnseitigen Ende die Kunststoffauskleidung entsprechend der Tiefe der Muffe als ein in diese einsteckbares Endstück vorsteht, wobei an dem genannten Endstück und oder der Muffe Einrichtungen, wie Klammern, Haken, Spannringe, Stege od. dgl., vorgesehen sind, um die nach oben wirkenden Spannkräfte nach dem Einstecken des Endstückes in die Muffe zur dichten Verbindung der Bauelemente aufzunehmen.The object is achieved by a component of the type mentioned, which is characterized in that the recess and the plastic lining are formed as a U-shaped sleeve with a, seen in cross section, U-shaped groove for receiving a seal at an end face of the concrete body and that from the other end the plastic lining protrudes according to the depth of the sleeve as an insertable into this end piece, facilities such as clamps, hooks, tension rings, webs or the like being provided on said end piece and or the sleeve, to absorb the upward-acting clamping forces after inserting the end piece into the sleeve for the tight connection of the components.

Mit dem Bauelement gemäß der Erfindung wird der wesentliche Vorteil erreicht, daß beim Verlegen durch einfaches Ineinanderstecken der einzelnen Bauelemente absolut dichte Rinnensysteme geschaffen werden können.With the component according to the invention, the main advantage is achieved that absolutely tight channel systems can be created by simply plugging the individual components into each other during installation.

Eine besondere Ausführungsform des erfindungsgemäßen Bauelementes besteht darin, daß über dem oben offenen Bereich des Endstückes ein mit einem nach oben gerichteten Absatz versehener Steg eingesetzt ist, und daß über dem oben offenen Bereich der Muffe ein mit einem nach unten gerichteten, entsprechenden Ansatz versehener Steg derart angeordnet ist, daß beim Einstecken des Endstükkes in die Muffe die beiden Stege über die Absätze zur dichten Verbindung der Bauelemente einrasten.A special embodiment of the component according to the invention is that a web provided with an upwardly directed shoulder is inserted over the open area of the end piece and that over the open area of the sleeve one with a Bottom facing, corresponding approach provided web is arranged so that when inserting the end piece in the sleeve, the two webs snap over the heels for the tight connection of the components.

Durch die beiden Stege wird nicht nur erreicht, daß die Verbindung sicher hergestellt wird, sondern daß auch die infolge der oben offenen Bereiche der Endstücke auftretenden, nach oben gerichteten Spannkräfte aufgenommen werden und sich somit nicht auf die Verschlechterung der Dichtung auswirken können.The two webs not only ensure that the connection is made securely, but also that the upward tension forces occurring as a result of the open areas of the end pieces are absorbed and thus cannot have an effect on the deterioration of the seal.

Eine weitere Ausführungsform des erfindungsgemäßen Bauelementes besteht darin, daß im Bereich des oben offenen Endstückes vorspringende Klammern vorgesehen sind, die beim Ineinanderstecken des Endstückes in die Muffe in entsprechende Aussparungen im Betonkörper einrasten.Another embodiment of the component according to the invention consists in the fact that in the area of the open top piece projecting clips are provided which snap into corresponding recesses in the concrete body when the end piece is inserted into the sleeve.

Schließlich können auch U-förmige Bügel das gesamte Endstück umschließen, um so beim Ineinanderstecken des Endstückes in die Muffe die nach oben gerichteten Spannkräfte aufzunehmen und eine dichte Verbindung zwischen den einzelnen Bauelementen herzustellen.Finally, U-shaped brackets can enclose the entire end piece in order to absorb the upward clamping forces when the end piece is inserted into the sleeve and to establish a tight connection between the individual components.

Anhand der Zeichnungen soll am Beispiel bevorzugter Ausführungsformen das Bauelement gemäß der Erfindung näher erläutert werden.The component according to the invention will be explained in more detail using the drawings using the example of preferred embodiments.

Wie sich aus den Figuren der Zeichnung ergibt, besteht das rechteckförmige Bauelement im wesentlichen aus einem Betonkörper 1, der eine U-förmige, rinnenförmige Aussparung 2 aufweist. Diese Aussparung ist mit einer Kunststoffauskleidung 3 versehen, die, wie bei 4 angezeigt, im Betonkörper 1 verankert ist. Das Bauelement gemäß der Erfindung ist mit einer im folgenden beschriebenen Steckverbindung versehen.As can be seen from the figures of the drawing, the rectangular component essentially consists of a concrete body 1 which has a U-shaped, channel-shaped recess 2. This recess is provided with a plastic lining 3, which, as indicated at 4, is anchored in the concrete body 1. The component according to the invention is provided with a plug connection described below.

An einem stirnseitigen Ende des Betonkörpers 1 sind die Aussparung und die Kunststoffauskleidung als Muffe 5 ausgebildet. Diese verbreiterte Muffe 5 weist eine im Querschnitt gesehen U-förmige Nut 6 auf, in die eine Dichtung 7 eingesetzt ist.At one end of the concrete body 1, the recess and the plastic lining are designed as a sleeve 5. This widened sleeve 5 has a U-shaped groove 6, seen in cross section, into which a seal 7 is inserted.

Vom anderen stirnseitigen Ende steht die Kunststoffauskleidung 3 als ein in die Muffe 5 einsteckbares Endstück 8 vor, wobei über den nach oben offenen Bereich des Endstückes ein mit einem nach oben gerichteten Absatz 9 versehener Steg 10 aus Metall eingesetzt ist. Ein entsprechender Steg 11 ist über den offenen Bereich der Muffe 5 mit einem nach unten gerichteten Absatz 12 eingesetzt.From the other end, the plastic lining 3 protrudes as an end piece 8 which can be inserted into the sleeve 5, a web 10 made of metal having an upwardly directed shoulder 9 being inserted over the area of the end piece which is open at the top. A corresponding web 11 is inserted over the open area of the sleeve 5 with a downwardly directed shoulder 12.

Wenn nun, wie in den Figuren 5 bis 8 gezeigt, das Endstück des folgenden Bauelementes in die Muffe des vorausgehenden Bauelementes eingesteckt wird, schiebt sich das oben etwas schräg ausgebildete Endstück 8 mit dem Steg 10 unter den Steg 11 der Muffe 5. Die einzelnen Phasen sind in den Figuren 6 bis 8 dargestellt. Beim Weiterschieben des Endstückes rastet schließlich der nach oben gerichtete Absatz 9 des Steges 10 in den nach unten gerichteten Absatz 12 des Steges 11 ein (Fig. 8), wodurch sich eine feste und dichte Verbindung ergibt. Dies ist insbesondere aus der unteren Detaildarstellung "II" ersichtlich.If, as shown in FIGS. 5 to 8, the end piece of the following component is inserted into the sleeve of the preceding component, the end piece 8 with a somewhat oblique design pushes with the web 10 under the web 11 of the sleeve 5. The individual phases are shown in Figures 6 to 8. When the end piece is pushed further, the upward heel 9 of the web 10 finally engages in the downward heel 12 of the web 11 (FIG. 8), resulting in a firm and tight connection. This can be seen in particular from the detailed illustration "II" below.

Wie sich aus Fig. 9 ergibt, sind anstelle des Steges am Endstück zwei nach außen springende Winkelstücke 13 vorgesehen, die nach dem Einschieben in die Muffe in entsprechende Aussparungen 14 im Betonkörper einrasten und somit auf diese Weise die nach oben wirkenden Spannkräfte aufnehmen.As can be seen from FIG. 9, instead of the web on the end piece, two outwardly protruding angle pieces 13 are provided which, after being inserted into the sleeve, snap into corresponding recesses 14 in the concrete body and thus absorb the tensioning forces acting upwards.
