Description

Die Erfindung betrifft einen Dachwasserablauf nach dem Oberbegriff von Anspruch 1.The invention relates to a roof water drain according to the preamble of claim 1.

Durch die DE-A-24 37 191 ist ein Ablauf für Flachdächer bekanntgeworden, bei welchem ein Kragen mit einer Dichtungs­bahn fest mit dem Ablaufkörper verbunden ist. Zum Auf­stocken wird in den Ablaufkörper ein einstückiges Aufsatz­element mit ebenfalls fest angebrachter Dichtungsbahn ein­gesetzt. Auch während der Bauphase ist der Kragen aufge­setzt und die Dichtungsbahn ausgelegt, was oft zu einer Ver­letzung derselben und zu späteren Undichtigkeiten führt.From DE-A-24 37 191 a drain for flat roofs has become known, in which a collar with a sealing membrane is firmly connected to the drain body. To stock up, a one-piece attachment element with a permanently attached sealing membrane is inserted into the drain body. Even during the construction phase, the collar is put on and the sealing membrane is laid out, which often leads to an injury to the same and to later leaks.

Der Erfindung liegt die Aufgabe zugrunde, einen Ablauf der eingangs genannten Gattung zu schaffen, der kostengünstig hergestellt werden kann und der unter Vermeidung des oben genannten Nachteils funktionssicher und einfach in der Montage ist.The invention has for its object to provide a sequence of the type mentioned that can be manufactured inexpensively and while avoiding the above mentioned disadvantage is reliable and easy to install.

Diese Aufgabe wird durch die im Patentanspruch 1 gezeich­nete Erfindung gelöst.This object is achieved by the invention drawn in claim 1.

Die herstellungstechnisch vergleichsweise aufwendigen Teile werden sowohl für den Aufsatzteil als auch für den Ablaufkörper verwendet, wodurch die Herstellung, die Lager­haltung und die Montage vereinfacht werden. Um eine Ver­letzung der Dichtungsbahn zu vermeiden, kann der Ablauf­körper während der Bauphase auch ohne Kragen für die provisorische Entwässerung verwendet werden.The parts, which are comparatively complex in terms of production technology, are used both for the top part and for the drain body, as a result of which the manufacture, storage and assembly are simplified. To avoid damaging the waterproofing membrane, the drain body can also be used without a collar for provisional drainage during the construction phase.

Gemäss einer vorzugsweisen Ausführung ist am Aufsatzteil ein Rohrstück angebracht, das in den Ablaufkörper einge­setzt ist. Dieses Rohrstück kann entsprechend der gewünsch­ten Höhe des Aufsatzes abgelängt werden. Gemäss einer weiteren Ausführung ist ein Einsatzkörper vorgesehen, der während der Bauphase in den Ablaufkörper eingesetzt wird. Damit ist auch während der Bauphase eine einwandfreie Ent­wässerung gewährleistet, und gleichzeitig ist der Einlauf vor Bauschutt geschützt. Weitere Ausgestaltungen der Erfin­dung sind in den abhängigen Patentansprüchen gekennzeichnet.According to a preferred embodiment, a piece of pipe is attached to the top part, which is inserted into the drain body. This piece of pipe can be cut to length according to the desired height of the attachment. According to a further embodiment, an insert body is provided which is inserted into the drain body during the construction phase. This guarantees perfect drainage even during the construction phase, and at the same time the inlet is protected against rubble. Further refinements of the invention are characterized in the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird nun anhand von Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 einen Schnitt durch einen in eine Decke eingebau­ten Ablaufkörper mit Aufsatzteil, und
  • Fig. 2 einen Schnitt durch einen eingebauten Ablaufkörper mit Einsatzkörper.
An embodiment of the invention will now be explained in more detail with reference to drawings. Show it:
  • Fig. 1 shows a section through a drain body built into a ceiling with attachment, and
  • Fig. 2 shows a section through a built-in drain body with insert body.

Der Ablauf weist einen aus Kunststoff bestehenden Ablauf­körper 1 mit einer äusseren, wärmedämmenden Isolations­schicht 24 beispielsweise aus PUR und einer inneren Schale 25 auf. An der Schale 25 ist mittig ein Stutzen 4 angeformt, der zu einem hier nicht dargestellten Fallrohr führt. Ueber der Oeffnung 3 des Stutzens ist ein Deckel 9 angebracht, der am Boden 2 der Schale befestigt ist. Der Deckel 9 weist Schlitze 10 in der Seitenwand 12 sowie Schlitze 11 in der Deckenwand 13 auf. Dieser Deckel erhöht in an sich bekannter Weise die Abflussleistung des Ablaufs und dient zugleich als zusätzliches Sieb. Der Ablaufkörper 1 besitzt eine kreiszylindrische Wand 40, die eine Wasser­sammelmulde 44 umgibt und die oben einen nach aussen ge­richteten Flansch 47 aufweist. Der Ablaufkörper 1 ist in einem Boden 30 eingegossen oder eingesetzt.The drain has a drain body 1 made of plastic with an outer, heat-insulating layer 24, for example made of PUR, and an inner shell 25. A socket 4 is integrally formed on the shell 25, which leads to a downpipe, not shown here. A cover 9 is attached above the opening 3 of the neck and is attached to the bottom 2 of the shell. The cover 9 has slots 10 in the side wall 12 and slots 11 in the top wall 13. This cover increases the drainage capacity of the drain in a manner known per se and also serves as an additional sieve. The drain body 1 has a circular cylindrical wall 40 which surrounds a water collecting trough 44 and which has an outwardly directed flange 47 at the top. The drain body 1 is cast or inserted into a base 30.

Eine ebene nach aussen gerichtete Dichtungsbahn 5, bei­spielsweise aus Polyvinylchlorid, ist am Flansch 45 eines Kragens 6 befestigt. Am Flansch 45 ist ein kreiszylindri­scher Stutzen 14 angeformt, der in die Wassersammelmulde 44 eingreift und in dessen Aussenseite 15 eine Lippendichtung 38 eingesetzt ist. Der Kragen 6 ist mittels einer Ring­dichtung oder Lippendichtung 7 gegen den Ablaufkörper 1 ab­gedichtet.A flat, outwardly directed sealing membrane 5, for example made of polyvinyl chloride, is attached to the flange 45 of a collar 6. A circular cylindrical connecting piece 14 is formed on the flange 45, which engages in the water collecting trough 44 and a lip seal 38 is inserted in the outside 15 thereof. The collar 6 is sealed against the drain body 1 by means of an annular seal or lip seal 7.

Ist, wie in Fig. 1 dargestellt, eine zusätzliche Boden­schicht 31 vorgesehen, so wird in den Ablaufkörper 1 ein Aufsatz 8 eingesetzt. Dieser besitzt einen Kragen 20, der genau dem Kragen 6 im unteren Teil des Ablaufs entspricht. Am Kragen 20 ist ebenfalls eine Dichtungsbahn 26 angeformt. Ebenfalls entspricht die kreiszylindrische Wandung 23 einer Schale 33 dem entsprechenden Wandbereich 43 der Schale 25. An der Schale 33 ist ein zylindrisches Rohr 22 angeformt. Das Rohr 22 steht mit dem unteren Rand auf dem Boden 2 der Schale 25. Dieses Rohr 22 wird bei der Montage je nach Dicke der Schicht 31 abgelängt. In die Oeffnung des Kragens 20 ist schliesslich ein Laubsieb 27 eingesetzt.If, as shown in FIG. 1, an additional bottom layer 31 is provided, an attachment 8 is inserted into the drain body 1. This has a collar 20 which corresponds exactly to the collar 6 in the lower part of the drain. A sealing membrane 26 is also formed on the collar 20. Likewise, the circular cylindrical wall 23 of a shell 33 corresponds to the corresponding wall area 43 of the shell 25. A cylindrical tube 22 is formed on the shell 33. The tube 22 stands with the lower edge on the bottom 2 of the shell 25. This tube 22 is cut to length depending on the thickness of the layer 31. Finally, a leaf sieve 27 is inserted into the opening of the collar 20.

Die Fig. 2 zeigt, wie der Ablauf für die provisorische Entwässerung während der Bauphase verwendet werden kann. Dazu wird der Ablaufkörper 1 ohne Kragen 6 in die Wand 30 eingesetzt. Provisorisch ist ein Einsatzkörper 28 aus bei­ spielsweise geschäumtem Polystyrol in die Wassersammel­mulde 44 eingesetzt. Dieser Körper 28 ist weitgehend komple­mentär zur Wassersammelmulde gestaltet und weist über dem Deckel 9 eine Oeffnung auf, durch die auf der Oberfläche der Schicht 30 ankommendes Wasser abfliessen kann. Zu gegebener Zeit wird der Einsatzkörper 28 entfernt und der Kragen 6 mit der Dichtungsbahn eingesetzt.Fig. 2 shows how the process for the provisional drainage can be used during the construction phase. For this purpose, the drain body 1 is inserted into the wall 30 without a collar 6. An insert body 28 is provisionally from for example foamed polystyrene used in the water collecting trough 44. This body 28 is largely complementary to the water collecting trough and has an opening above the cover 9 through which water arriving on the surface of the layer 30 can flow off. The insert body 28 is removed at the appropriate time and the collar 6 with the sealing membrane is inserted.

Die Schalen 33 und 43 werden aus dem gleichen Rohling her­gestellt. Für die Schale 43 wird dann jeweils das Rohr 22 entfernt und der Boden 2 mit dem Stutzen 4 angeschweisst. Auf der Unterseite des Bodens 2 sind Heizelemente I7 ange­bracht, mit deren Hilfe Schwitzwasser im Ablaufkörper 1 ent­fernt werden kann.The shells 33 and 43 are made from the same blank. For the shell 43, the tube 22 is then removed in each case and the base 2 is welded to the socket 4. On the underside of the bottom 2, heating elements I7 are attached, by means of which condensation water in the drain body 1 can be removed.
