Die vorliegende Erfindung betrifft eine Dachablaufvorrichtung gemäß dem Oberbegriff des Anspruchs 1 sowie die Anordnung einer derartigen Dachablaufvorrichtung an einem Dach.The present invention relates to a roof drainage device according to the preamble of claim 1 and the arrangement of such a roof drainage device to a roof.

Eine Dachablaufvorrichtung der vorgenannten Art ist beispielsweise aus der DE 102 01 347 A1 bekannt. Als nachteilig bei einer derartigen Dachablaufvorrichtung erweist sich die Tatsache, dass im Brandfall Feuer von unten durch die Dachablaufvorrichtung auf das Dach oder durch die Wärmedämmung des Daches hindurchdringen oder in die Wärmedämmung des Daches eindringen kann. Auf dem Dach beziehungsweise in dem Dach kann sich das Feuer in Querrichtung verbreiten, so dass sich dadurch das Feuer auch in dem unter dem Dach befindlichen Gebäude in Querrichtung ausbreiten kann.A roof drain device of the aforementioned type is for example from the DE 102 01 347 A1 known. A disadvantage of such a roof drainage device proves to be the fact that fire can penetrate from below through the roof drain device on the roof or through the thermal insulation of the roof or penetrate into the thermal insulation of the roof in case of fire. On the roof or in the roof, the fire can spread in the transverse direction, so that it can spread the fire in the building located under the roof in the transverse direction.

Aus der EP 1 362 961 A1 ist eine Ablaufvorrichtung bekannt, die in eine Öffnung in einem Boden eines Raumes einbaubar ist. Diese Ablaufvorrichtung weist ein teilweise aus Metall bestehendes Teil auf, das auf seiner Innenseite mit einer bei erhöhter Temperatur aufschäumenden Brandschutzmasse versehen ist. Von diesem Teil wird ein Ablauftopf gehalten, der einen sich nach unten in das Teil erstreckenden Rohrstutzen aufweist.From the EP 1 362 961 A1 For example, a draining device is known which can be installed in an opening in a floor of a room. This drainage device has a partially made of metal part, which is provided on its inside with a foaming at elevated temperature fire protection compound. From this part, a drain pot is held, which has a downwardly extending into the part pipe socket.

Aus der DE 201 01 589 U1 ist eine weitere Ablaufvorrichtung bekannt, die in eine Öffnung in einem Boden eines Raumes einbaubar ist. Diese Ablaufvorrichtung umfasst einen Ablauftopf mit einem sich nach unten erstreckenden Rohrstutzen, der mit einem Abflussrohr verbindbar ist. Die Ablaufvorrichtung umfasst weiterhin einen aus Metall bestehenden Schutzkasten, der den Ablauftopf teilweise umgibt. Es sind bei erhöhter Temperatur aufschäumende Brandschutzmassen vorgesehen, die Teile des Ablauftopfes und des Abflussrohres umgeben.From the DE 201 01 589 U1 For example, another draining device is known which can be installed in an opening in a floor of a room. This drainage device comprises a drain pot with a downwardly extending pipe socket, which is connectable to a drain pipe. The drainage device further comprises a protective metal box which partially surrounds the drainage pot. There are foaming at elevated temperature Provided fire protection compounds that surround parts of the drain pot and the drain pipe.

Das der vorliegenden Erfindung zugrunde liegende Problem ist die Schaffung einer Dachablaufvorrichtung der eingangs genannten Art, die einen besseren Schutz im Falle eines Brandes bietet.The problem underlying the present invention is to provide a roof drain device of the type mentioned, which provides better protection in the event of a fire.

Dies wird erfindungsgemäß durch eine Dachablaufvorrichtung der eingangs genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche betreffen bevorzugte Weiterbildungen der Erfindung.This is inventively achieved by a roof drain device of the type mentioned above with the characterizing features of claim 1. The subclaims relate to preferred developments of the invention.

Dadurch, dass die Dachablaufvorrichtung Brandschutzmittel umfasst, kann weitgehend verhindert werden, dass Feuer und Rauch von unten nach oben durch das Dach dringen oder in das Dach eindringen kann.The fact that the roof drainage device includes fire protection can be largely prevented that fire and smoke from the bottom upwards penetrate through the roof or can penetrate into the roof.

Beispielsweise können die Brandschutzmittel als bei einer erhöhten Temperatur ausschäumende Brandschutzmasse ausgebildet sein, die insbesondere zumindest teilweise das Ablaufrohr und/oder einen von der Dachablaufvorrichtung umfassten Ablauftopf umgibt. Im Brandfall kann die Brandschutzmasse unter starker Volumenvergrößerung aufschäumen und das Ablaufrohr und/oder den Ablauftopf zusammendrücken, so dass die für die Dachablaufvorrichtung vorgesehene Öffnung im Dach geschlossen wird.For example, the fire protection means may be designed as a fire protection compound which foams at an elevated temperature and which, in particular, at least partially surrounds the drainage pipe and / or a drainage pot encompassed by the roof drainage device. In case of fire, the fire protection compound can foam under strong increase in volume and squeeze the drain pipe and / or drain pot, so that provided for the roof drain device opening in the roof is closed.

Alternativ oder zusätzlich kann vorgesehen sein, dass die Brandschutzmasse zumindest teilweise im Inneren des Ablauftopfes angeordnet ist. Auf diese Weise kann sich auch im Inneren des Ablauftopfes im Brandfall unmittelbar Brandschutzmasse ausdehnen.Alternatively or additionally, it may be provided that the fire protection compound is at least partially disposed in the interior of the drain pot. In this way, even in the interior of the drain pot in case of fire directly fire protection compound can expand.

Erfindungsgemäß umfasst die Dachablaufvorrichtung eine metallische Umhüllung, die zumindest teilweise den Ablauftopf und/oder das Abflussrohr umgibt. Dabei kann die Umhüllung die Brandschutzmasse daran hindern, sich nach außen auszudehnen, so dass der Expansionsdruck der Brandschutzmasse nach innen gerichtet wird.According to the invention, the roof drainage device comprises a metallic enclosure which at least partially surrounds the Drain pot and / or the drain pipe surrounds. In this case, the envelope may prevent the fire protection compound from expanding to the outside, so that the expansion pressure of the fire protection compound is directed inwards.

Erfindungsgemäß umfasst die Umhüllung einen, sich radial von der Umhüllung nach außen erstreckenden Flansch. Dieser kann beispielsweise die für die Dachablaufvorrichtung im Dach vorgesehene Öffnung radial nach außen überragen, so dass von unten kein Feuer und kein Rauch durch die Öffnung nach oben durchschlagen oder in das Dach eindringen kann.According to the invention, the sheath comprises a flange extending radially outward from the sheath. This can, for example, project beyond the opening provided for the roof drainage device in the roof opening radially outwards, so that from below no fire and no smoke can penetrate through the opening upwards or penetrate into the roof.

Die aus Fig. 1 ersichtliche Dachablaufvorrichtung umfasst einen Ablauftopf 1 mit einer Einlauföffnung, die auf ihrer Oberseite mit einem Laubfang 2 abgedeckt ist. Der Laubfang kann aus Nirostastahl oder aus Kunststoff oder dergleichen bestehen. Der Ablauftopf 1 besteht ebenfalls aus Kunststoff. Die Dachablaufvorrichtung ist teilweise in eine Öffnung 3 in dem Betondach 4 eingesetzt. Der Ablauftopf 1 kann in üblicher Weise in seinem oberen Bereich einen Flansch 19 aufweisen oder mit einem Flansch 19 verbunden sein, der auf der Oberseite des Daches aufliegen kann (siehe dazu beispielsweise Fig. 2b).From Fig. 1 apparent roof drain device comprises a drain pot 1 with an inlet opening, which is covered on its upper side with a leaf trap 2. The leaf catch may consist of stainless steel or plastic or the like. The drain pot 1 is also made of plastic. The roof drainage device is partially inserted into an opening 3 in the concrete roof 4. The drain pot 1 may have in the usual way in its upper region a flange 19 or be connected to a flange 19 which may rest on the top of the roof (see, for example Fig. 2b ).

Die Dachablaufvorrichtung umfasst weiterhin eine Brandschutzeinheit 5, die einen Teller 6 mit einem daran angeformten, sich nach unten erstreckenden Stutzen 7 umfasst. Der Teller 6 weist dabei einen Radius auf, der etwa dem Durchmesser der Öffnung 3 entspricht, so dass oberhalb des Tellers 6 Mörtel oder dergleichen eingefüllt werden kann. Auf dem Teller 6 und an der Innenseite des Stutzens 7 ist eine Brandschutzmasse 8 vorgesehen, die als Intumeszenzschaum ausgebildet sein kann, der bei erhöhter Temperatur sein Volumen deutlich vergrößert. Im Brandfall kann dieser Intumeszenzschaum sich insbesondere im Bereich des Stutzens 7 radial nach innen bewegen und die Öffnung 3 komplett verschließen. Dabei können der an der Unterseite des Ablauftopfes 1 angeformte Stutzen 9 und das mit diesem verbundene Abflussrohr 10 von der Brandschutzmasse zerquetscht werden.The roof drainage device further comprises a fire protection unit 5, which comprises a plate 6 with a downwardly extending nozzle 7 formed thereon. The plate 6 in this case has a radius which corresponds approximately to the diameter of the opening 3, so that above the plate 6 mortar or the like are filled can. On the plate 6 and on the inside of the nozzle 7, a fire protection compound 8 is provided, which may be formed as an intumescent foam, which significantly increases its volume at elevated temperature. In the event of fire, this intumescent foam can move radially inwards, in particular in the region of the connecting piece 7, and completely close the opening 3. In this case, the integrally formed on the underside of the drain pot 1 nozzle 9 and connected to this drain pipe 10 can be crushed by the fire protection compound.

Es besteht durchaus die Möglichkeit, andere Brandschutzmittel vorzusehen. Beispielsweise besteht die Möglichkeit anstelle der Brandschutzeinheit 5 mit Teller und Stutzen eine untere Rohrmanschette um den Stutzen 9 des Ablauftopfes 1 und/oder um das Abflussrohr 10 herum anzuordnen. Dabei könnte beispielsweise an der Außenseite der Brandschutzmanschette, die innen ebenfalls eine umlaufende Brandschutzmasse umfassen kann, entweder Mörtel oder eine Metallummantelung vorgesehen sein.It is quite possible to provide other fire protection products. For example, instead of the fire protection unit 5 with plate and socket, it is possible to arrange a lower pipe sleeve around the socket 9 of the drain pot 1 and / or around the drain pipe 10. In this case, for example, mortar or a metal casing could be provided on the outside of the fire protection sleeve, which may also include a circumferential fire protection compound inside.

Weiterhin besteht die Möglichkeit, eine Brandschutzmasse im Inneren des Ablauftopfes 1 vorzusehen. Diese könnte beispielsweise im Brandfall in eine bestimmte Höhe des Ablauftopfes 1 fallen und sich an dieser Stelle, beispielsweise im Bereich der Verjüngung des Ablauftopfes im Verbindungsbereich mit dem Stutzen 9, ausbreiten und an dieser Stelle den Ablauftopf nach außen quetschen und die Öffnung 3 verschließen.Furthermore, it is possible to provide a fire protection compound in the interior of the drain pot 1. This could fall, for example, in case of fire in a certain height of the drain pot 1 and at this point, for example in the region of the taper of the drain pot in the connection area with the nozzle 9, spread and squeeze the drain pot to the outside and close the opening 3 at this point.

Auch weitere Anordnungen einer Brandschutzmasse sind möglich. Beispielsweise besteht die Möglichkeit den Ablauftopf zumindest teilweise ringförmig mit einer Brandschutzmasse zu umgeben. Beispielsweise könnte außerhalb des Rohrstutzens 11, der sich in dem abgebildeten Ausführungsbeispiel von dem Teller 6 nach oben erstreckt, eine sich um diesen Rohrstutzen herum erstreckende Brandschutzmanschette aus einer Brandschutzmasse vorgesehen sein. In diesem Fall könnte auch auf die Brandschutzeinheit 5 verzichtet werden, weil dann in einem höher angeordneten Bereich eine sich radial nach innen ausdehnende Brandschutzmasse vorgesehen ist.Other arrangements of a fire protection compound are possible. For example, it is possible to surround the drain pot at least partially annular with a fire protection compound. For example, could outside the pipe socket 11, located in the illustrated embodiment extends from the plate 6 upwards, be provided around this pipe socket around extending fire protection sleeve of a fire protection compound. In this case, could also be dispensed with the fire protection unit 5, because then in a higher area arranged a radially inwardly expanding fire protection compound is provided.

Fig. 2a bis Fig. 2c zeigen die Anordnung einer erfindungsgemäßen Dachablaufvorrichtung in einem Industriedach, insbesondere in einem sogenannten Trapezdach, bei dem eine untere metallische Abdeckung 12 vorgesehen ist, die teilweise eine trapezförmige Gestalt aufweist. Bei Fig. 2a bis Fig. 2c sind gleiche Teile mit gleichen Bezugszeichen versehen wie in Fig. 1. Insbesondere weist die darin abgebildete Dachablaufvorrichtung ebenfalls einen Ablauftopf 1 mit einem Laubfang 2 auf. In den teilweise doppelwandig ausgeführten Ablauftopf 1 sind Wärmedämmeinlagen 14, 15 beispielsweise aus Styropor eingebracht. Der Ablauftopf 1 ist insgesamt von einer äußeren metallischen Umhüllung 13 umgeben, die in ihrem unteren Bereich zylindrisch ausgebildet ist. An ihrer Oberseite weist die Umhüllung 13 einen sich radial nach außen erstreckenden Flansch 18 auf, der die Öffnung 3 radial nach außen überragt. Die Umhüllung 13 kann beispielsweise aus Stahl bestehen. Fig. 2a to Fig. 2c show the arrangement of a roof drainage device according to the invention in an industrial roof, in particular in a so-called trapezoidal roof, in which a lower metallic cover 12 is provided, which partially has a trapezoidal shape. at Fig. 2a to Fig. 2c are the same parts with the same reference numerals as in Fig. 1 , In particular, the roof drain device depicted therein also has a drain pot 1 with a leaf trap 2. In the partially double-walled drain pot 1 thermal insulation inserts 14, 15, for example made of polystyrene introduced. The drain pot 1 is surrounded by a total of an outer metal sheath 13 which is cylindrical in its lower portion. On its upper side, the sheath 13 has a flange 18 extending radially outwards, which projects beyond the opening 3 radially outward. The envelope 13 may for example consist of steel.

Weiterhin ist der untere Bereich des Ablauftopfes 1 von einer Brandschutzmasse 16 umgeben, die insbesondere an der Innenseite der Umhüllung 13 angebracht ist.Furthermore, the lower region of the drain pot 1 is surrounded by a fire protection compound 16, which is attached in particular to the inside of the enclosure 13.

Die Dachablaufvorrichtung umfasst weiterhin eine sich horizontal erstreckende Wärmedämmeinlage 17, die beispielsweise einen Durchmesser von etwa einem Meter aufweist. Die Wärmedämmeinlage 17 kann aus Mineralwolle oder dergleichen bestehen und beispielweise temperaturbeständig sein.The roof drain device further comprises a horizontally extending thermal insulation insert 17, for example, has a diameter of about one meter. The thermal insulation insert 17 may consist of mineral wool or the like and, for example, be temperature resistant.

Im Brandfall wird die Brandschutzmasse 16, die beispielsweise aus einem Intumeszenzschaum bestehen kann, sich ausdehnen und sich radial nach innen erstrecken. Dabei wird sie den Ablauftopf 1, den an diesem angeformten Stutzen 9 und das Abflussrohr 10 zerquetschen und die lichte Öffnung der Stahlumhüllung 13 verschließen, so dass kein Feuer und auch kein Rauch von unten nach oben hindurch schlagen oder in das Dach eindringen kann.In case of fire, the fire protection compound 16, which may for example consist of an intumescent, expand and extend radially inwards. In doing so, it will crush the drain pot 1, the nozzle 9 formed thereon and the drain pipe 10, and close the clear opening of the steel casing 13, so that no fire or smoke can penetrate from below upwards or penetrate into the roof.

Fig. 2c zeigt ein Dach, das im Vergleich zu dem in Fig. 2a abgebildeten Dach eine größere Dicke aufweist. Trotzdem kann die gleich erfindungsgemäße Dachablaufvorrichtung Verwendung finden. Fig. 2c lässt sich entnehmen, dass im Vergleich zur Fig. 2a der Ablauftopf 1 gegenüber der Umhüllung 13 nach oben verschoben wurde. Damit kann trotz gleicher Höhe der Einlauföffnung des Ablauftopfes 1 bzw. des die Einlauföffnung umgebenden, auf dem Dach aufliegenden Flansches 19 (siehe Fig. 2b) der Flansch 18 der Umhüllung 13 an der Unterseite des Daches anliegen. Fig. 2c shows a roof that compared to the one in Fig. 2a pictured roof has a greater thickness. Nevertheless, the roof drain device according to the invention can be used. Fig. 2c can be seen that compared to Fig. 2a the drain pot 1 relative to the enclosure 13 has been moved upwards. Thus, despite the same height of the inlet opening of the drain pan 1 and the surrounding the inlet opening, resting on the roof flange 19 (see Fig. 2b ) abut the flange 18 of the enclosure 13 at the bottom of the roof.

Auch bei der Vorrichtung gemäß Fig. 2a bis Fig. 2c können im Zusammenhang mit Fig. 1 diskutierte Varianten realisiert werden. Beispielsweise können Brandschutzmanschetten um das Abflussrohr 10 herumgelegt werden. Weiterhin besteht auch die Möglichkeit, ein innerhalb des Ablauftopfes 1 vorgesehenes Brandschutzmittel vorzusehen, das ebenfalls im Brandfall aufschäumen kann und die Öffnung in dem Dach verschließen kann.Also in the device according to Fig. 2a to Fig. 2c can be related to Fig. 1 discussed variants are realized. For example, fire protection sleeves can be wrapped around the drainpipe 10. Furthermore, there is also the possibility to provide a provided within the drain pot 1 fire protection, which can also foam in the event of fire and can close the opening in the roof.

Die erfindungsgemäße Dachablaufvorrichtung sollte die Anforderungen gemäß den Feuerwiderstandsklassen F 30 bis F 90 erfüllen sowie der DIN 18234 genügen.The roof drainage device according to the invention should meet the requirements according to the fire resistance classes F 30 to F 90 and satisfy DIN 18234.
