Der insbesondere als Dachablauf auf versiegelten ebenen Dachflรคchen bestimmte Wasserablauf 1 umfaรŸt einen Basiskรถrper 2 und einen Aufsatzkรถrper 3. Der Basiskรถrper 2 ist mit einem ringfรถrmigen Plattenteil 4 versehen, der auf der zu entwรคssernden ebenen Flรคche aufgelegt oder oberseitig bรผndig mit der Flรคche abschlieรŸend in diese eingelassen wird. Ferner umfaรŸt der Basiskรถrper 2 einen zentralen Muldenteil 5, aus dem bodenseitig eine zentrale Ablaufรถffnung 6 ausmรผndet, an die sich ein Ablaufstutzen 7 anschlieรŸt, der in Einbaustellung in das obere Ende eines Ablaufrohres eingreift.The particular intended as a roof drain on sealed flat roof surfaces Water outlet 1 comprises a base body 2 and an attachment body 3. The base body 2 is provided with an annular plate member 4 which is to be drained on the flat surface laid on top or flush with the surface is embedded in this. Furthermore, the base body 2 comprises a central Trough part 5, from the bottom side opens a central drain opening 6, to the a drainage pipe 7 connects, in the installed position in the upper end of a Drainpipe engages.

Der Aufsatzkรถrper 3 weist eine ebene, in Zusammenbaustellung der Teile den Muldenteil 2 zentral รผbergreifende Abdeckplatte 8 auf, die unterseitig mit zumindest drei hochkant stehenden, radial ausgerichteten Distanzstegen 9 versehen ist, mit denen sich der Aufsatzkรถrper 3 auf dem ringfรถrmigen Plattenteil 4 des Basiskรถrpers 2 abstรผtzt. Die Distanzstege 9 sind vorzugsweise mit gleichen Winkelabstรคnden รผber den Umfang der Abdeckplatte 8 verteilt. Anstelle von drei Distanzstegen 9 kรถnnen auch deren vier oder mehr vorgesehen sein. In Zusammenbaustellung der Teile begrenzt die Abdeckplatte 8 mit dem Plattenteil 4 des Basiskรถrpers 2 eine umlaufende Einlaufรถffnung 10, die in der Hรถhe verhรคltnismรครŸig gering ausgefรผhrt werden kann, so daรŸ sie unmittelbar selbst als Laub- und Steinfรคnger wirksam ist. Der Aufsatzkรถrper 3 kann mittels รผblicher Befestigungsmittel wie Schrauben o.รค. mit dem Basiskรถrper 2 verbunden werden (nicht dargestellt).The attachment body 3 has a flat, in the assembled position of the parts the container part 2 centrally overlapping cover plate 8, the underside with at least three standing upright, radially aligned spacer webs 9 is provided, with which the attachment body 3 is supported on the annular plate part 4 of the base body 2. The spacer webs 9 are preferably over at equal angular intervals the scope of the cover plate 8 distributed. Instead of three spacer bars 9 can also be provided four or more. Limited in the assembled position of the parts the cover plate 8 with 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 a leaf and Steinfรคnger. The tower body 3 can by means of conventional fasteners such as screws o.รค. with the base body 2 are connected (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 ausgefรผhrt sein kรถnnen. Die Lamellen 11 wirken mit ihren AuรŸenkanten 12 als Laub- und Kiesfรคnger und mit ihren einander zugewandten Hauptflรคchen als Leitelemente zur Strรถmungsberuhigung und -ausrichtung von anstrรถmendem Wasser, wenn der Wasserpegel infolge entsprechender Regenfรคlle oder sonstiger Ursachen รผber die Oberseite der Abdeckplatte 8 ansteigt.On the upper side, the cover plate 8 has freely upwardly projecting, radially aligned, vertical slats 11, which with the cover plate 8 - as well as the Distance webs 9 - can be made integral. The fins 11 act with their Outer edges 12 as foliage and gravel trap and with their facing each other Main surfaces as guiding elements for flow calming and orientation of inflowing water when the water level due to corresponding rains or other causes on the top of the cover plate 8 increases.

Die Lamellen 11 liegen in einem Ringbereich und bilden einen Kranz, wobei sie mit ihren AuรŸenrรคndern 12 an den AuรŸenrand 13 der Abdeckplatte 8 unmittelbar angrenzen. Zwischen ihren AuรŸenrรคndern 12 begrenzen die Lamellen 11 Durchtrittsรถffnungen 14, deren Breite, in Umfangsrichtung gemessen, etwa dem halben mittleren Durchmesser der Kiesel einer Kiesauflage auf der zu entwรคssernden Flรคche entspricht. Die Breite kann dementsprechend zwischen 10-30 mm betragen und bewegt sich vorzugsweise bei etwa 15 mm - 20 mm. Die Hรถhe der Durchtrittsรถffnungen 14 zwischen den AuรŸenrรคndern 12 der Lamellen 11 entspricht dem 1,5 - 3,0-fachen der ร–ffnungsbreite, und betrรคgt vorzugsweise etwa das Zweifache. In der radialen Erstreckung weisen die Lamellen 11 eine Lรคnge auf, die etwa dem 1,5 - 2,5-fachen der Hรถhe der Durchtrittsรถffnungen 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, about half the middle Diameter of the pebbles of a gravel layer on the surface to be drained equivalent. The width can accordingly be between 10-30 mm and moved preferably at about 15 mm - 20 mm. The height of the passages 14 between the outer edges 12 of the fins 11 corresponds to 1.5 - 3.0 times the opening width, and is preferably about twice. In the radial Extension, the fins 11 have a length which is about 1.5 to 2.5 times the height of the passage openings 14, preferably about 1.75 times, corresponds.

In dem von den Lamellen 11 eingenommenen Ringbereich weist die Abdeckplatte 8 einen radial auรŸerhalb des AuรŸenrandes 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 Durchtrittsรถffnungen 14 zwischen den AuรŸenrรคndern 12 der Lamellen 11 entspricht. Der AuรŸenrand 17 des Ringschlitzes 16 liegt vorzugsweise in einem Abstand zum AuรŸenrand 13 der Abdeckplatte 8, der zumindest etwa der Ringschlitzbreite entspricht. Der Ringschlitz 16 bildet dementsprechend eine EinlaรŸรถffnung fรผr Wasser, die fรผr sich allein, jedenfalls aber in Verbindung mit der EinlaรŸรถffnung 10 zwischen dem AuรŸenrand 13 der Abdeckplatte 8 und dem AuรŸenrand 18 des Plattenteils 4 des Basiskรถrpers 2 ausreicht, um den Wasserablauf 1 problemlos mit jener maximalen Wassermenge zu versorgen, die durch die Ablaufรถffnung 6 hindurchtreten und in das AbfluรŸrohr gelangen kann.In the annular area occupied by the slats 11, the cover plate 8 a ring slot 16 located radially outside the outer edge 15 of the trough 5 which preferably has a width in the radial direction of about 0.5 to 1.5 times, preferably about the width of the passage openings 14 simple between the outer edges 12 of the fins 11 corresponds. The outer edge 17 of Ring 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 ring slot 16 accordingly forms an inlet for water, in itself, anyway but 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 part 4 of the base body 2 is sufficient, to provide the water drain 1 easily with that maximum amount of water, which pass through the drain opening 6 and enter the drainpipe can.

Wie oben schon erwรคhnt wird die Hรถhe der Einlaufรถffnung 10 durch die Distanzstege 9 bestimmt, und diese Distanzstege weisen zweckmรครŸig eine Hรถhe auf, die etwa dem 0,5 - 1,5-fachen, vorzugsweise etwa dem Einfachen der Breite der Durchtrittsรถffnungen 14 zwischen den AuรŸenrรคndern 12 der Lamellen 11 betrรคgt. Die Einlaufรถffnung 10 hat damit eine Durchtrittsflรคche, die einen stets unbehinderten Wasserdurchtritt gewรคhrleistet. Durch die radialen Distanzstege 9 ist dabei auch gesichert, daรŸ in dem von den Distanzstegen 9 eingenommenen, unterseitigen Ringbereich keine nennenswerten Wirbel- oder Strudelbildungen eintreten kรถnnen. Da die Distanzstege 9 mit ihren inneren Enden zumindest bis an den AuรŸenrand 15 der Mulde 5 im Basiskรถrper 2 heranreichen, tritt auch innerhalb der Mulde 5 keine Wirbel- oder Strudelbildung mehr auf, da das Wasser bis zum Erreichen der Ablaufรถffnung 6 angesichts seiner Strรถmungsgeschwindigkeit hierfรผr keine Gelegenheit mehr hat. Erforderlichenfalls kรถnnen allerdings auch in der Mulde 5 noch radiale, den Lamellen 11 รคhnliche Leitstege angebracht werden, die mit ihren Innenrรคndern dann etwa an den Umfang der Ablaufรถffnung 6 heranreichen.As mentioned above, the height of the inlet opening 10 through the spacer webs 9 determined, and these spacer bars expediently have a height that about 0.5 to 1.5 times, preferably about 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 is always an unobstructed water passage guaranteed. By the radial spacer webs 9 is also secured, that in the occupied by the spacer webs 9, lower-side ring area no appreciable eddy or vortex formations can occur. Because the spacer bars 9 with their inner ends at least up to the outer edge 15 of the trough 5 in the base body 2, also occurs within the trough 5 no vortex or vortex formation more because the water until reaching the drain opening. 6 in view of its flow rate for this no longer has an opportunity. If necessary, however, even in the trough 5 radial, the fins 11 similar guide webs are attached, with their inner edges then approximately reach the periphery of the drain opening 6.

Steigt der Wasserpegel auf der zu entwรคssernden ebenen Flรคche รผber die Oberseite der Abdeckplatte 8 hinaus an, kann zusรคtzlich 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 Einlaufรถffnung 10 zur Ablaufรถffnung 6 strรถmende Wasser รผbt auf das Wasser oberhalb des Ringschlitzes 16 eine einer Wasserstrahlpumpe รคhnliche Saugwirkung aus, wobei das in den Wasserstrom unterhalb der Abdeckplatte 8 durch den Ringschlitz 16 eintretende Wasser zur Beruhigung und VergleichmรครŸigung der Wasserstrรถmung beitrรคgt, so daรŸ der Wasserablauf eine bezogen auf die vorgegebenen Abmessungen maximale Abwassermenge entsorgt.If the water level on the flat surface to be drained rises above the top the cover plate 8 addition, water can additionally through the annular slot 16 in enter the interior of the water outlet 1, this water from a is given by the slats 16 predetermined calming and accordingly in turn has no tendency to turbulence. That 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 of a water jet pump similar suction effect, which in the water flow below the cover plate 8 entering through the annular slot 16 water for reassurance and homogenization contributes to the flow of water, so that the water drain a related disposed of to the given dimensions maximum amount of waste water.
