Der insbesondere als Dachablauf auf versiegelten ebenen Dachflächen bestimmte Wasserablauf 1 umfaßt einen Basiskörper 2 und einen Aufsatzkörper 3. Der Basiskörper 2 ist mit einem ringförmigen Plattenteil 4 versehen, der auf der zu entwässernden ebenen Fläche aufgelegt oder oberseitig bündig mit der Fläche abschließend in diese eingelassen wird. Ferner umfaßt der Basiskörper 2 einen zentralen Muldenteil 5, aus dem bodenseitig eine zentrale Ablauföffnung 6 ausmündet, an die sich ein Ablaufstutzen 7 anschließt, der in Einbaustellung in das obere Ende eines Ablaufrohres eingreift.The particular as a roof drain on sealed flat roof surfaces certain water outlet 1 comprises a base body 2 and a top body 3. The base body 2 is provided with an annular plate member 4, which rests on the flat surface to be drained or the top flush with the surface is embedded in this. Furthermore, the base body 2 comprises a central bowl part 5, from the bottom side a central drain opening 6 opens, to which a drain pipe 7 connects, which engages in the installed position in the upper end of a drain pipe.

Der Aufsatzkörper 3 weist eine ebene, in Zusammenbaustellung der Teile den Muldenteil 2 zentral übergreifende Abdeckplatte 8 auf, die unterseitig mit zumindest drei hochkant stehenden, radial ausgerichteten Distanzstegen 9 versehen ist, mit denen sich der Aufsatzkörper 3 auf dem ringförmigen Plattenteil 4 des Basiskörpers 2 abstützt. Die Distanzstege 9 sind vorzugsweise mit gleichen Winkelabständen über den Umfang der Abdeckplatte 8 verteilt. Anstelle von drei Distanzstegen 9 können auch deren vier oder mehr vorgesehen sein. In Zusammenbaustellung der Teile begrenzt die Abdeckplatte 8 mit dem Plattenteil 4 des Basiskörpers 2 eine umlaufende Einlauföffnung 10, die in der Höhe verhältnismäßig gering ausgeführt werden kann, so daß sie unmittelbar selbst als Laub- und Steinfänger wirksam ist. Der Aufsatzkörper 3 kann mittels üblicher Befestigungsmittel wie Schrauben o.ä. mit dem Basiskörper 2 verbunden werden (nicht dargestellt).The attachment body 3 has a flat, in the assembled position of the parts the trough part 2 centrally cross-cover plate 8, which is provided on the underside with at least three upstanding, radially aligned spacer webs 9, with which the attachment body 3 is supported on the annular plate member 4 of the base body 2 , The spacer webs 9 are preferably distributed over the circumference of the cover plate 8 at equal angular intervals. Instead of three spacer webs 9 and their four or more can be provided. In the assembled position of the parts, the cover plate 8 limits the plate part 4 of the base body 2 a circumferential inlet opening 10, which can be made relatively low in height, so that it is directly effective even as foliage and Steinfänger. The attachment body 3 can by means of conventional fasteners such as screws o.ä. be connected to the base body 2 (not shown).

Auf der Oberseite weist die Abdeckplatte 8 frei nach oben vorstehende, radial ausgerichtete, vertikale Lamellen 11 auf, die mit der Abdeckplatte 8 - ebenso wie die Distanzstege 9 - integral ausgeführt sein können. Die Lamellen 11 wirken mit ihren Außenrändern bzw. Außenkanten 12 als Laub- und Kiesfänger und mit ihren einander zugewandten Hauptflächen als Leitelemente zur Strömungsberuhigung und -ausrichtung von anströmendem Wasser, wenn der Wasserpegel infolge entsprechender Regenfälle oder sonstiger Ursachen über die Oberseite der Abdeckplatte 8 ansteigt.On the upper side, the cover plate 8 freely upwardly projecting, radially aligned, vertical fins 11, which can be performed with the cover plate 8 - as well as the spacer webs 9 - integral. The fins 11 act with their outer edges or outer edges 12 as foliage and gravel trap and with their major faces facing each other as guiding elements for flow calming and orientation of inflowing water when the water level rises due to corresponding rains or other causes on the top of the cover plate 8.

Die Lamellen 11 liegen in einem Ringbereich und bilden einen Kranz, wobei sie mit ihren Außenrändern 12 an den Außenrand 13 der Abdeckplatte 8 unmittelbar angrenzen. Zwischen ihren Außenrändern 12 begrenzen die Lamellen 11 Durchtrittsöffnungen 14, deren Breite, in Umfangsrichtung gemessen, etwa dem halben mittleren Durchmesser der Kiesel einer Kiesauflage auf der zu entwässernden Fläche entspricht. Die Breite kann dementsprechend zwischen 10-30 mm betragen und bewegt sich vorzugsweise bei etwa 15 mm - 20 mm. Die Höhe der Durchtrittsöffnungen 14 zwischen den Außenrändern 12 der Lamellen 11 entspricht dem 1,5 - 3,0-fachen der Öffnungsbreite, und beträgt vorzugsweise etwa das Zweifache. In der radialen Erstreckung weisen die Lamellen 11 eine Länge auf, die etwa dem 1,5 - 2,5-fachen der Höhe der Durchtrittsöffnungen 14, vorzugsweise etwa dem 1,75-fachen, entspricht.The fins 11 lie in a ring area and form a wreath, with their outer edges 12 directly adjacent to the outer edge 13 of the cover plate 8. Between their outer edges 12, the fins 11 limit passages 14, whose width, measured in the circumferential direction, corresponds to approximately half the mean diameter of the pebbles of a gravel support on the surface to be drained. The width can accordingly be between 10-30 mm and preferably moves at about 15 mm - 20 mm. The height of the passage openings 14 between the outer edges 12 of the fins 11 corresponds to 1.5 to 3.0 times the opening width, and is preferably about twice. In the radial extent, the lamellae 11 have a length which corresponds approximately to 1.5-2.5 times the height of the passage openings 14, preferably approximately 1.75 times.

In dem von den Lamellen 11 eingenommenen Ringbereich weist die Abdeckplatte 8 einen radial außerhalb des Außenrandes 15 der Mulde 5 gelegenen Ringschlitz 16 auf, der vorzugsweise in radialer Richtung eine Breite hat, die etwa dem 0,5 - 1,5-fachen, vorzugsweise etwa dem Einfachen der Breite der Durchtrittsöffnungen 14 zwischen den Außenrändern 12 der Lamellen 11 entspricht. Der Außenrand 17 des Ringschlitzes 16 liegt vorzugsweise in einem Abstand zum Außenrand 13 der Abdeckplatte 8, der zumindest etwa der Ringschlitzbreite entspricht. Der Ringschlitz 16 bildet dementsprechend eine Einlaßöffnung für Wasser, die für sich allein, jedenfalls aber in Verbindung mit der Einlaßöffnung 10 zwischen dem Außenrand 13 der Abdeckplatte 8 und dem Außenrand 18 des Plattenteils 4 des Basiskörpers 2 ausreicht, um den Wasserablauf 1 problemlos mit jener maximalen Wassermenge zu versorgen, die durch die Ablauföffnung 6 hindurchtreten und in das Abflußrohr gelangen kann.In the annular region occupied by the lamellae 11, the cover plate 8 has a ring slot 16 located radially outside the outer edge 15 of the trough 5, which preferably has a width in the radial direction which is approximately 0.5-1.5 times, preferably approximately 0.5 the simplicity of the width of the passage openings 14 between the outer edges 12 of the fins 11 corresponds. The outer edge 17 of the annular slot 16 is preferably at a distance from the outer edge 13 of the cover plate 8, which corresponds at least approximately to the annular slot width. The annular slot 16 accordingly forms an inlet opening for water, which in itself, but in any case in conjunction with the inlet opening 10 between the outer edge 13 of the cover plate 8 and the outer edge 18 of the plate member 4 of the base body 2 is sufficient to the water drain 1 easily with that maximum To supply amount of water that can pass through the drain opening 6 and get into the drain pipe.

Wie oben schon erwähnt wird die Höhe der Einlauföffnung 10 durch die Distanzstege 9 bestimmt, und diese Distanzstege weisen zweckmäßig eine Höhe auf, die etwa dem 0,5 - 1,5-fachen, vorzugsweise etwa dem Einfachen der Breite der Durchtrittsöffnungen 14 zwischen den Außenrändern 12 der Lamellen 11 beträgt. Die Einlauföffnung 10 hat damit eine Durchtrittsfläche, die einen stets unbehinderten Wasserdurchtritt gewährleistet. Durch die radialen Distanzstege 9 ist dabei auch gesichert, daß in dem von den Distanzstegen 9 eingenommenen, unterseitigen Ringbereich keine nennenswerten Wirbel- oder Strudelbildungen eintreten können. Da die Distanzstege 9 mit ihren inneren Enden zumindest bis an den Außenrand 15 der Mulde 5 im Basiskörper 2 heranreichen, tritt auch innerhalb der Mulde 5 keine Wirbel- oder Strudelbildung mehr auf, da das Wasser bis zum Erreichen der Ablauföffnung 6 angesichts seiner Strömungsgeschwindigkeit hierfür keine Gelegenheit mehr hat. Erforderlichenfalls können allerdings auch in der Mulde 5 noch radiale, den Lamellen 11 ähnliche Leitstege angebracht werden, die mit ihren Innenrändern dann etwa an den Umfang der Ablauföffnung 6 heranreichen.As mentioned above, the height of the inlet opening 10 is determined by the spacer webs 9, and these spacer webs expediently have a height which is about 0.5 to 1.5 times, preferably approximately the width of the passage openings 14 between the outer edges 12 of the fins 11 is. The inlet opening 10 thus has a passage surface, which always unobstructed water passage guaranteed. By the radial spacer webs 9 is also ensured that in the occupied by the spacer webs 9, underside ring area no significant vortex or vortex formations can occur. Since the spacer webs 9 come with their inner ends at least up to the outer edge 15 of the trough 5 in the base body 2, occurs within the trough 5 no vortex or vortex formation more, since the water until reaching the drain opening 6 in view of its flow rate for this no Opportunity has more. If necessary, however, even in the trough 5 radial, the fins 11 similar guide webs can be attached, which then zoom with their inner edges approximately to the circumference of the drain opening 6.

Steigt der Wasserpegel auf der zu entwässernden ebenen Fläche über die Oberseite der Abdeckplatte 8 hinaus an, kann zusätzlich Wasser durch den Ringschlitz 16 in den Innenraum des Wasserablaufs 1 eintreten, wobei dieses Wasser aus einem durch die Lamellen 16 vorgegebenen Beruhigungsbereich entnommen wird und dementsprechend seinerseits keine Tendenz zu Turbulenzen hat. Das unterhalb der Abdeckplatte 8 von der Einlauföffnung 10 zur Ablauföffnung 6 strömende Wasser übt auf das Wasser oberhalb des Ringschlitzes 16 eine einer Wasserstrahlpumpe ähnliche Saugwirkung aus, wobei das in den Wasserstrom unterhalb der Abdeckplatte 8 durch den Ringschlitz 16 eintretende Wasser zur Beruhigung und Vergleichmäßigung der Wasserströmung beiträgt, so daß der Wasserablauf eine bezogen auf die vorgegebenen Abmessungen maximale Abwassermenge entsorgt.If the water level on the flat surface to be drained above the top of the cover plate 8 addition, water can also enter through the annular slot 16 in the interior of the water outlet 1, this water is removed from a predetermined by the slats 16 calming and accordingly in turn no Has tendency to turbulence. The below the cover plate 8 from the inlet opening 10 to the drain opening 6 flowing water exerts on the water above the annular slot 16 a similar to a water jet pump suction, wherein the entering into the water flow below the cover plate 8 through the annular slot 16 water for calming and evening out the flow of water contributes, so that the water drain disposed of a maximum based on the given dimensions wastewater.

Als günstig hat sich ergeben, wenn der Durchmesser der Abdeckplatte 8 etwa 320 mm , des Plattenteils 4 etwa 300 mm, der Ablauföffnung 6 etwa 70 mm und der Mulde 5 etwa 130 mm beträgt, wobei die Lamellenhöhe etwa 60 mm und die Ringschlitzbreite etwa 15 mm betragen kann.As low has been found, when the diameter of the cover plate 8 is about 320 mm, the plate member 4 about 300 mm, the drain opening 6 is about 70 mm and the trough 5 is about 130 mm, wherein the lamella height about 60 mm and the annular slot width about 15 mm can amount.
