Description

Die Erfindung bezieht sich auf einen Bodenablauf für den Sanitärbereich, der in eine Kernbohrung einer Betondecke eines Gebäudes einsetzbar ist, mit einem dem Fußbodenbelag des sanitären Raumes zugeordneten Aufsatz und mit einer den Aufsatz aufnehmenden Ablaufglocke, deren Auslaufstutzen mit einem Abflußrohr strömungsfähig verbindbar ist.The invention relates to a floor drain for the sanitary area, in a Core hole of a concrete floor of a building is used, with a the floor covering the sanitary room assigned essay and with an essay receiving drain bell, the outlet nozzle flowable with a drain pipe is connectable.

Die Kernbohrung wird mittels eines geeigneten Werkzeuges in die Betondecke eingegossen und ist demzufolge maßgenau. Es ist jedoch auch möglich, dass der Bodenablauf in einen Durchbruch eingesetzt wird. Ferner besteht auch die Möglichkeit, dass im Zuge einer Sanierung eines Gebäudes der Bodenablauf in ein vorhandenes Rohr eingesetzt wird, welches vermörtelt ist.The core hole is poured into the concrete floor using a suitable tool and is therefore dimensionally accurate. However, it is also possible that the floor drain is used in a breakthrough. There is also the option of that in the course of a renovation of a building, the floor drain into an existing Pipe is used, which is mortared.

Der in Rede stehende Bodenablauf ist insbesondere für Naßzellen eines Gebäudes geeignet. Er soll verhindern, daß beispielsweise aus einer Versorgungsleitung ausströmendes Wasser in die angrenzenden Räume des Gebäudes gelangt. Der Auslaufstutzen ist mit dem Abflußrohr verbunden, welches Teil eines geschlossenen Rohrsystems ist, welches an den Abwasserkanal angeschlossen ist. Die Ablaufglocke ist so ausgelegt, daß eine gewisse Menge Wasser darin stehenbleibt, um den sogenannten Geruchverschluß zu bilden. Der Aufsatz des Bodenablaufs liegt zum größten Teil oberhalb der oberen Fläche der Betondecke und wird beim Verlegen des Estriches und des Fußbodenbelages sinngemäß eingemauert. Damit der Bodenablauf kein Loch im Fußboden bildet, ist der Ablauf an der oberen Seite durch ein Rost abgedeckt. Dadurch wird auch der eigentliche Bodenablauf zugänglich, beispielsweise um Verstopfungen zu beseitigen.The floor drain in question is in particular for wet cells of a building suitable. He should prevent, for example, from a supply line effluent Water enters the adjacent rooms of the building. The spout is connected to the drainpipe, which is part of a closed pipe system is, which is connected to the sewer. The drain bell is designed so that a certain amount of water remains in the so-called To form an odor trap. The attachment of the floor drain is the largest Part above the upper surface of the concrete ceiling and is when laying the screed and the floor covering immemorial walled. So that the floor drain no Hole in the floor forms, the drain at the upper side is covered by a rust. As a result, the actual floor drain is accessible, for example to eliminate blockages.

Die Durchbrüche in einer Betondecke werden heutzutage nicht mehr durch Einsetzen eines Styroporklotzes in die Schalung erstellt, sondern die Betondecke wird öffnungsfrei vergossen und es werden anschließend mittels geeigneter Werkzeuge die Durchbrüche erstellt. Der Zwischenraum zwischen der Innenfläche der Kernbohrung und des Bodenablaufes wird anschließend mit Mörtel verfüllt. Dies sind für den den Bodenablauf einsetzenden Installateur artfremde Arbeiten, so daß der zuständige Fachmann im Anschluß diese Arbeiten verrichten muß. Naturgemäß werden jedoch diese Arbeiten nicht immer fachmännisch durchgeführt. Es ist jedoch einschlägig vorgeschrieben, daß ein Bodenablauf im Brandfall über einen vorgeschriebenen Zeitraum rauch- und feuerdicht sein muß. Das Verfüllen mit Mörtel ist deshalb äußerst gewissenhaft durchzuführen. Daraus ergibt sich, daß es auch sehr zeit- und somit kostenaufwendig ist. Um die Sicherheit zu erhöhten ist es bekannt, ein Dichtelement in den Zwischenraum einzusetzen, welches bei einer Wärmeeinwirkung von beispielsweise 100 °C aufquillt. Diese bekannten Bodenabläufe haben sich zwar bestens bewährt, jedoch ist deren Einsetzen in die Durchbrüche der Betondecke recht aufwendig.The breakthroughs in a concrete ceiling are nowadays no longer by inserting a Styroporklotzes created in the formwork, but the concrete ceiling is opening shed and it will then be using appropriate tools the Breakthroughs created. The space between the inner surface of the core hole and the floor drain is then filled with mortar. These are for the Floor installation installer alien works, so that the competent Professional following this work must do. Naturally, however This work is not always done expertly. It is, however, relevant prescribed that a floor drain in case of fire over a prescribed Period must be smoke and fire-proof. The filling with mortar is therefore extremely conscientiously perform. It follows that it is very time and thus expensive. For safety reasons, it is known a sealing element in the space to be used, which in a heat of For example, 100 ° C swells. These known floor drains have indeed well proven, however, is their insertion in the breakthroughs of the concrete pavement quite expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen Bodenablauf der eingangs näher beschriebenen Art so zu gestalten, daß er vom Installateur in äußerst kurzer Zeit in die Kernbohrung eingesetzt werden kann, und daß darüber hinaus auf das aufwendige Verfüllen des Zwischenraumes zwischen dem Bodenablauf und der Innenfläche der Kernbohrung mit Mörtel verzichtet werden kann.The invention is based on the object, a floor drain the beginning closer described in such a way that it by the installer in a very short time in the core hole can be used, and that in addition to the elaborate Filling the space between the floor drain and the inner surface The core hole can be dispensed with mortar.

Die gestellte Aufgabe wird gelöst, indem der Bodenablauf zur Zentrierung innerhalb der Kernbohrung im äußeren Bereich mit mindestens drei Federkrallen versehen ist, und daß der Bodenablauf im unteren, dem Aufsatz abgewandten Bereich mit einer eine Rauchbremse bildenden Dichtanordnung versehen ist. The task is solved by the floor drain for centering within the core hole in the outer area is provided with at least three spring claws, and that the floor drain in the lower, the tower facing away from the area with a a smoke brake forming sealing arrangement is provided.

Die Federkrallen sind so ausgelegt, daß sie sich sehr stark verformen können bzw. daß der Federweg quer zur Durchflußrichtung des Bodenablaufes relativ groß ist, so daß in allen Fällen sichergestellt ist, daß sie noch eine gewisse Kraft auf die Innenfläche der Kernbohrung im eingesetzten Zustand ausüben. Sinngemäß wird durch die Federkrallen eine Selbstzentrierung des Bodenablaufes erreicht. Da sie aus einem Federwerkstoff bestehen, beispielsweise aus Federstahl, sind sie extrem hitzebeständig. Die Dichtanordnung im unteren Bereich ist so ausgelegt, daß zumindest über den vorgeschriebenen Zeitraum verhindert wird, daß Rauch durch den Ringraum zwischen dem Bodenablauf und der Innenfläche der Kernbohrung durchströmen kann. Dadurch kann auf das zeit- und kostenintensive Verfüllen des Ringraumes mit Mörtel verzichtet werden. Der Bodenablauf kann aufgrund seiner Auslegung in äußerst kurzer Zeit von einem Installateur in die Kernbohrung eingesetzt werden, so daß die Montage kostengünstig erfolgen kann.The spring claws are designed so that they can deform very much or that the spring travel is relatively large transversely to the flow direction of the floor drain, so that in all cases it is ensured that they still have a certain force on the inner surface exercise the core hole in the inserted state. By analogy is through the spring claws achieved a self-centering of the floor drain. Since they are from one Spring material consist, for example spring steel, they are extremely heat resistant. The sealing arrangement in the lower region is designed so that at least Over the prescribed period of time, smoke is prevented from passing through the annulus flow between the bottom drain and the inner surface of the core hole can. This can on the time and cost-intensive filling of the annulus to be dispensed with mortar. The floor drain can be due to its design Installed in the core hole in a very short time by an installer be so that the assembly can be done inexpensively.

Die Dichtanordnung kann aus mehreren Dichtelementen bestehen. So enthält sie beispielsweise eine die Innenfläche der Kernbohrung kontaktierende Lippendichtung, die in der Projektion gesehen, ringförmig gestaltet ist. Die Lippendichtung ist aus einem wärmebeständigen Material, so daß sie im Brandfall über einen ausreichenden Zeitraum die Funktion aufrecht erhalten wird. Diese Lippendichtung ist zweckmäßigerweise an eine Scheibe angesetzt, die in bevorzugter Ausführung aus Stahl besteht. Die Lippendichtung könnte beispielsweise an die Scheibe anvulkanisiert sein. Die Dichtanordnung enthält außerdem eine Flanschhülse, die ein unter Wärmeeinwirkung aufquellbares Material enthält. Die ist so in den unteren Bereich des Bodenablaufes eingesetzt, daß der rohrförmige Bereich das Abflußrohr umgreift, während der Flansch dem Aufsatz zugewandt liegt. Die Scheibe mit der angesetzten Lippendichtung kontaktiert den Flansch an der dem Aufsatz abgewandten Seite. Dadurch wird eine intensive Schutzwirkung erreicht. Damit die Wirkung der Lippendichtung voll gegeben ist, ist der Durchmesser des Flansches der Flanschhülse etwa genauso groß wie der Innendurchmesser der Lippendichtung. In bevorzugter Ausführung ist der Durchmesser ein klein wenig größer. Die Federkrallen sind in bevorzugter Ausführung aus einem Flachstab gefertigt und verlaufen bogenförmig, wobei der mittlere Bereich den größten Durchmesser aufweist. Im nicht eingesetzten Zustand ist der größte Durchmesser der durch die Federkrallen im mittleren Bereich gebildet wird, größer als der Innendurchmesser der Kernbohrung, so daß die Federkrallen beim Einsetzen verformt werden, so daß die Rückstellkräfte auf die Innenfläche der Kernbohrung drücken, so daß der Bodenablauf kraftschlüssig in der Kernbohrung gehalten wird. Die Sicherung gegen eine Verschiebung des Bodenablaufes innerhalb der Kernbohrung wird noch erhöht, wenn die Federkrallen im mittleren Bereich nach außen gerichtete Zähne aufweisen, die beispielsweise sägezahnförmig gestaltet sind, wobei die Spitzen nach außen zeigen. Die Spitzen kontaktieren dann die Innenfläche der Kernbohrung. Die Federkrallen sind lose mit dem Körper des Bodenablaufes verbunden, d.h. die Enden greifen in Taschen oder Nuten ein. Die Länge der noch nicht angesetzten Federkrallen ist so ausgelegt, daß sie beim Ansetzen an den Körper des Bodenablaufes die bogenförmige Form bilden.The sealing arrangement may consist of several sealing elements. So it contains for example, a lip seal contacting the inner surface of the core bore, seen in the projection, is ring-shaped. The lip seal is made of a heat-resistant material, so that in case of fire on a sufficient Period the function is maintained. This lip seal is Appropriately attached to a disc, in a preferred embodiment of Steel exists. For example, the lip seal could be vulcanized to the pane be. The sealing assembly also includes a flange sleeve, a below Heat action contains swellable material. It's so in the lower part the bottom drain used, that the tubular area surrounds the drain pipe, while the flange is facing the attachment. The disc with the attached Lip seal contacts the flange on the side facing away from the attachment. Thereby an intensive protective effect is achieved. Thus the effect of the lip seal is fully given, the diameter of the flange of the flange sleeve is about the same as the inner diameter of the lip seal. In a preferred embodiment the diameter is a little bit bigger. The spring claws are in preferred Made of a flat bar and run arcuately, with the central area has the largest diameter. In the unused state is the largest diameter of the spring claws in the middle area is formed, larger than the inner diameter of the core bore, so that the spring claws deformed during insertion, so that the restoring forces on the inner surface Press the core hole, so that the floor drain frictionally in the Core hole is held. The protection against a displacement of the floor drain within the core hole is further increased when the spring claws in the middle Area outwardly facing teeth, for example, sawtooth are designed with the tips facing outward. Contact the tips then the inner surface of the core hole. The spring claws are loose with the body connected to the floor drain, i. the ends engage in pockets or grooves. The length of not yet scheduled spring claws is designed so that they Attach to the body of the floor drain forming the arcuate shape.
