Abstract
Description
Die Erfindung bezieht sich auf einen Bodenablauf für den Sanitärbereich, der in einen als Kernbohrung ausgeführten Durchbruch einer Betondecke eines Gebäudes einsetzbar ist, mit einem dem Fußbodenbelag des Sanitärbereichs zugeordneten Aufsatz und mit einer den Aufsatz aufnehmenden Ablaufglocke, deren Auslaufstutzen mit einem Abflußrohr strömungsfähig verbindbar ist, wobei der Bodenablauf im unteren, dem Aufsatz abgewandten Bereich mit einer eine Rauchbremse bildenden Dichtanordnung versehen ist, die so ausgelegt ist, dass zumindest über einen vorgegebenen Zeitraum verhindert wird, dass Rauch durch den Ringraum zwischen der Ablaufglocke und der Innenfläche des Durchbruchs strömen kann.The invention relates to a floor drain for the sanitary area, which can be used in a core hole perforation of a concrete floor of a building, associated with a floor covering of the sanitary area essay and with a tower receiving the drain bell whose outlet is fluidly connected to a drainpipe, wherein the bottom drain in the lower, the tower facing away from the area is provided with a smoke barrier forming a sealing arrangement which is designed so that at least over a predetermined period of time prevents smoke can flow through the annulus between the drain bell and the inner surface of the opening.
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 by means of a suitable tool in the concrete ceiling and is therefore dimensionally accurate. However, it is also possible that the floor drain is used in a breakthrough. Furthermore, there is also the possibility that in the course of a renovation of a building, the floor drain is inserted into an existing pipe, 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 particularly suitable for wet cells of a building. He should prevent, for example, from a supply line escaping water enters the adjacent rooms of the building. The spout is connected to the drainpipe, which is part of a closed pipe system 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 located for the most part above the upper surface of the concrete floor and is walled in when laying the screed and the floor covering mutatis mutandis. So that the floor drain does not form a hole in the floor, the drain on the upper side is covered by a grate. This also makes the actual floor drain 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 pavement are nowadays no longer created by inserting a Styroporklotzes in the formwork, but the concrete ceiling is potted open-minded and then the breakthroughs are created by means of suitable tools. The space between the inner surface of the core hole and the floor drain is then filled with mortar. These are alien to the floor installer installer, so that the competent professional must perform this work subsequently. Naturally, however, this work is not always performed expertly. However, it is pertinently required 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 conscientious. It follows that it is very time consuming and thus costly. To increase safety, it is known to use a sealing element in the intermediate space, which swells at a heat of, for example, 100 ° C. Although these known floor drains have proven their worth, their insertion into the openings in the concrete floor is rather complicated.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Bodenablauf der eingangs genannten Art so zu gestalten, dass er vom Installateur in äußerst kurzer zeit in einen als Kernbohrung ausgeführten Durchbruch eingesetzt werden kann, und dass darüber hinaus auf das aufwendige Verfüllen des Zwischenraumes zwischen Bodenablauf und der Innenfläche der Kernbohrung mit Mörtel verzichtet werden kann.The present invention has for its object to make a floor drain of the type mentioned so that it can be used by the installer in a very short time in a run as a core hole breakthrough, and that in addition to the costly backfilling of the gap between the floor drain and the Inner surface of the core hole can be dispensed with mortar.
Gelöst wird diese Aufgabe durch den Bodenablauf mit den Merkmalen des Anspruchs 1.This problem is solved by the floor drain with the features of claim 1.
Der erfindungsgemäße Bodenablauf ist dadurch gekennzeichnet, dass an die Ablaufglocke außen mindestens drei Federkrallen angesetzt sind, die der Zentrierung des Bodenablaufs innerhalb des Durchbruchs der Betondecke dienen, wobei die Federkrallen aus einem Flachmaterial gefertigt sind und im nicht eingesetzten Zustand bogenförmig an der Ablaufglocke angesetzt sind, so dass sie unter Bildung von Rückstellkräften im eingesetzten Zustand die Innenfläche des Durchbruchs flächig kontaktieren.The floor drain according to the invention is characterized in that at least three spring claws are attached to the drain bell outside, which serve to center the floor drain within the opening of the concrete ceiling, the spring claws are made of a flat material and are applied in the unused state arcuately on the drain bell, so that they contact flat surface with the formation of restoring forces in the inserted state, the inner surface of the opening.
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 exert a certain force on the inner surface of the core hole in the inserted state , Analogously, a self-centering of the floor drain is achieved by the spring claws. Since they are made of a spring material, such as spring steel, they are extremely heat resistant. The sealing arrangement in the lower area is designed so that at least over the prescribed period of time it is prevented that smoke can flow through the annular space between the floor drain and the inner surface of the core bore. This can be dispensed with the time-consuming and cost-intensive filling of the annular space with mortar. The floor drain can be used by an installer in the core hole due to its design in a very short time, so that the installation 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. Sie 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. Thus, for example, it contains a lip seal which contacts the inner surface of the core bore and, viewed in the projection, has a ring-shaped design. The lip seal is made of a heat-resistant material, so that it is maintained in the event of a fire for a sufficient period of time the function. This lip seal is expediently attached to a disc, which consists of steel in a preferred embodiment. The lip seal could, for example, be vulcanized onto the pane. The sealing assembly also includes a flange sleeve containing a heat swellable material. The is inserted into the lower portion of the floor drain, that the tubular portion 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. As a result, an intensive protective effect is achieved. So that the effect of the lip seal is fully satisfied, the diameter of the flange of the flange sleeve is about the same size as the inner diameter of the lip seal. In a preferred embodiment, the diameter is a little larger. The spring claws are made in a preferred embodiment of a flat bar. They are arcuate, with the central area having the largest diameter. In the unused state, the largest diameter of the spring claws in the middle region is formed, larger than the inner diameter of the core bore, so that the spring claws are deformed during insertion, so that the restoring forces press on the inner surface of the core bore, so that the Bodenablauf is held frictionally in the core bore. The protection against displacement of the floor drain within the core bore is further increased when the spring claws in the central region have outwardly directed teeth, which are designed, for example, sawtooth-shaped, with the tips facing outward. The tips then contact the inner surface of the core bore. The spring claws are loosely connected to the body of the floor drain, ie the ends engage in pockets or grooves. The length of the not yet scheduled spring claws is designed so that they form the arcuate shape when applied to the body of the floor drain.
