Abstract

A drain device for draining flat roofs, balconies, terraces or other flat structures, has an inflow body provided with a collar rim. When the inflow body is mounted, the collar rim lies on the surface of the roof. A loose flange can be introduced into the inflow body. The flange also has a collar rim. A connector film can be tensed between the collar rims of the inflow body and the loose flange for establishing a tight connection of a covering layer between said two elements. In order to allow for abnormally large amounts of water to be drained, the inflow body is provided with a cavity, into which two drain pipes and lead. One of the drain pipes co-operates with a pressurized, i.e., a pumped drainage system, and the other one of the drain pipes cooperates with a free-flowing drainage system.

Description

Die Erfindung betrifft eine Vorrichtung zur Entwässerung von Flachdächern. Balkonen, Terrassen oder anderen Flachbauten, die aus einem Einlaufkörper mit einem Kragenrand besteht, der im eingesetzten Zustand des Einlaufkörpers auf der Dachfläche aufliegt, und wobei in den Einlauf ein Losflansch einsteckbar ist, der ebenfalls einen Kragenrand aufweist, und wobei zwischen dem Kragenrand von Einlaufkörper und Losflansch eine Anschlussfolie eingelassen ist, die zur dichtenden, herstellenden Verbindung einer Deckschicht zwischen diesen verspannbar ist.The invention relates to a device for drainage of flat roofs. Balconies, terraces or other low-rise buildings made up of one Inlet body with a collar edge, which is in the inserted state of the inlet body rests on the roof surface, and being in the inlet a loose flange can be inserted, which also has a collar edge has, and being between the collar edge of the inlet body and loose flange a connection film is inserted, which is used for sealing, producing connection of a cover layer can be clamped between them is.

Derartige Vorrichtungen werden dazu benutzt, gezielt und sicher das auf der Fläche eines Flachdaches, einer Terrasse bzw. eines Balkones anfallende Wasser in ein Abflussrohr einzuleiten. Von Wichtigkeit ist dabei, dass der Randbereich der Öffnung in dem Baukörper derart abgedichtet ist, dass das Wasser nicht an den Wänden herunterläuft, sondern gezielt in das Abflussrohr eingeleitet wird. Derartige Vorrichtungen bezeichnet man auch als Gully, wobei der Gully aus einem Einlaufkörper besteht, der meist trichterförmig ausgebildet ist und aus einem Losflansch, der in den Einlaufkörper einsteckbar ist. Um einen sicheren und dichtenden Anschluss, beispielsweise auf einer Bitumenbahn, herstellen zu können, wird der Losflansch auf den Einlaufkörper gesteckt und kann auf diesem verspannt werden. Hierzu weist sowohl der Einlaufkörper als auch der Losflansch einen Kragenrand auf, der im gesteckten Zustand einen Spalt aufweist, in dem dann die Anschlussfolie oder die Bitumenbahn eingefügt werden kann.Such devices are used for this purpose, specifically and safely on the surface of a flat roof, a terrace or a balcony discharge water into a drain pipe. It is important thereby ensuring that the edge area of the opening in the structure is sealed in this way is that the water doesn't run down the walls, but is specifically directed into the drain pipe. Such devices is also called a gully, where the gully consists of one Inlet body exists, which is usually funnel-shaped and from a loose flange that can be inserted into the inlet body. Around a secure and sealing connection, for example on a Bitumen membrane, to be able to manufacture, the loose flange on the Inlet body inserted and can be clamped on this. For this both the inlet body and the loose flange have one Collar edge, which has a gap when plugged in which then the connection film or the bitumen sheet are inserted can.

DE-A-19819116 offenbart eine derartige Entwässerungsvorrichtung.DE-A-19819116 discloses such a drainage device.

Bei der Dachentwässerung unterscheidet man zwischen zwei Entwässerungsprinzipien, wobei das Freispiegelsystem viele Fallleitungen zur Entwässerung vorhält, wohingegen das Druckentwässerungssystem nur über eine geringe Anzahl von Fallleitungen entwässert. Die Leistungsfähigkeit des Druckwassersystems wird häufig dadurch beeinträchtigt, dass bei der Entwässerung Luft mit angesaugt wird, was sich unwillkürlich durch einen Wasserwirbel und einen Luftzapfen, der sich im Einlaufkörper bildet, einstellt. Die Strömung des Wassers im Rohr wird dadurch beeinträchtigt, so dass die Ablaufleistung der Druckentwässerungsanlage gemindert ist. Zudem bietet das Druckentwässerungssystem keine Gewährleistung dafür, dass beispielsweise bei auftretendem Jahrhundertwasser die anfallenden Wassermengen mit einem Druckwassersystem abgeführt werden können. Hierzu ist es dann erforderlich, dass ein Freispiegelsystem vorgehalten werden muss um ein sicheres Entwässern der Dachflächen zu gewährleisten. Entsprechendes gilt auch für eine einfache Entwässerung mit einem Fallrohr.With roof drainage, a distinction is made between two drainage principles, the free-mirror system for many downpipes Drainage lasts, whereas the pressure drainage system only drained through a small number of downpipes. The efficiency the pressurized water system is often affected by that air is sucked in during drainage, which is involuntary by a vortex of water and an air cone, which is in the Inlet body forms, adjusts. The flow of water in the pipe is affected, so that the drainage performance of the pressure drainage system is diminished. The pressure drainage system also offers no guarantee that, for example, Century water the amount of water with a pressurized water system can be dissipated. It is then necessary to that a free mirror system must be kept in order to be safe Ensure drainage of the roof surfaces. The same also applies to simple drainage with a downpipe.

Hier setzt die Aufgabe der Erfindung an, bei der ein Entwässerungssystem derart weitergebildet werden soll, das insbesondere auch die Möglichkeit bietet, Jahrhundertwassermengen zu verarbeiten.This is where the object of the invention begins, in which a drainage system should be further developed in such a way, in particular that Possibility to process volumes of water from the century.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Der Einlaufkörper weist eine Kammer auf, in der zwei Ablaufrohre münden, wobei das eine Ablaufrohr und das andere Ablaufrohr mit Druck- oder Freispiegelentwässerungssystemen zusammenwirken. Auf Grund der Kombination von zwei Entwässerungssystemen bzw. der Kombination von zwei Ablaufrohren in einem Einlaufkörper wird erreicht, dass das bewährte Druckentwässerungssystem einerseits mit einem Freispiegelentwässerungssystem andererseits kombiniert in einem Einlaufkörper angeordnet werden kann. Somit kann in Folge des Einbaus eines Einlaufkörpers die Normalmenge von anfallendem Regenwasser von der Dachfläche abgezogen werden, wobei insbesondere, wenn ein Jahrhundertregen auftreten sollte, durch dieselbe Entwässerungsvorrichtung auch eine wesentlich größere Wassermenge abgeführt werden kann, die dann entsprechend durch das größere Ablaufrohr abläuft. Durch diese Kombination der Entwässerungssysteme ergibt sich für den einzelnen installierten Gully eine höhere Sicherheit hinsichtlich des abzuführenden Wassers, wobei ein derartig ausgelegter Gully dort einzusetzen ist, wo die gefährdeten Wassermengen auf dem Dach auftreten können.This object is solved by the features of claim 1. The enema body has a chamber in which two drain pipes open, wherein the one drain pipe and the other drain pipe with pressure or Open-level drainage systems work together. Due to the Combination of two drainage systems or the combination of two drain pipes in one inlet body ensures that that proven pressure drainage system with one Free-level drainage system, on the other hand, combined in one Inlet body can be arranged. Thus, as a result of the installation of an inlet body the normal amount of rainwater be deducted from the roof area, especially if it rains a century should occur through the same drainage device a much larger amount of water can also be removed, which then runs through the larger drain pipe. By this combination of drainage systems results for the individual installed gully a higher security regarding the water to be drained, using a gully designed in this way is where the endangered amounts of water appear on the roof can.

Hierzu weist die Einlaufkammer im wesentlichen einen flach ausgebildeten Boden auf, in dem einerseits der Einlaufstutzen des Ablaufrohres direkt in dem Boden des Einlaufkörpers mündet, wobei der Einlaufstutzen des anderen Ablaufrohres durch den flach ausgebildeten Boden des Einlaufkörpers hindurchragt und dessen Einlaufstutzen somit oberhalb der Einlaufkammer mündet. Somit wird gewährleistet, dass einerseits das Entwässerungssystem in der Kammer störungsfrei arbeitet, indem die Einlaufkammer sich zunächst mit Wasser füllt, so dass das in dem Boden der Einlaufkammer mündende Ablaufrohr gefüllt wird. Steigt die Menge des anfallenden Regens, so steigt der Wasserspiegel in der Einlaufkammer an, bis er etwa den Horizont des Einlaufstutzen des anderen Ablaufrohres erreicht. In Folge des größeren Durchmessers des Ablaufrohres zur Freispiegelentwässerung kann die entsprechend überschüssig anfallende Regenmenge dann durch das Ablaufrohr der Freispiegelentwässerung abgeführt werden.For this purpose, the inlet chamber essentially has a flat bottom, in which on the one hand the inlet connector the drain pipe opens directly into the bottom of the inlet body, the inlet pipe of the other drain pipe through the flat bottom of the inlet body protrudes through it Inlet nozzle thus opens above the inlet chamber. Thus ensures that the drainage system in the chamber works trouble-free by first using the inlet chamber Fills water so that the drain pipe opens into the bottom of the inlet chamber is filled. If the amount of rain increases, so the water level in the inlet chamber rises until it Horizon of the inlet pipe of the other drain pipe reached. In Result of the larger diameter of the drain pipe Free-level drainage can result in excess Rainfall then through the drain pipe of the free-level drainage be dissipated.

In Weiterbildung der Erfindung ist an dem Losflansch mittels Distanzelementen eine scheibenförmige Abdeckung mit einer Öffnung vorgesehen, durch die der Einlaufstutzen der Freispiegelentwässerung ragt. Dies ermöglicht eine radiale Anströmung in die Kammer des Einlaufkörpers. In a development of the invention is on the loose flange by means of spacers a disk-shaped cover with an opening is provided, through which the inlet of the free-level drainage projects. This enables a radial inflow into the chamber of the inlet body.

Zur Vermeidung von Wirbeln in dem Einlaufstutzen des Ablaufrohres zur Druckentwässerung ist unterhalb der Abdeckung eine weitere Abdeckung für den Einlaufstutzen angeordnet, soweit er mit einem Druckentwässerungssystem zusammenwirkt. Die Abdeckung bewirkt, dass sich im Bereich der Einlaufkammer auch eine radiale Anströmung für den Einlaufstutzen der Druckentwässerung einstellt.To avoid eddies in the inlet pipe of the drain pipe Pressure drainage is another cover below the cover arranged for the inlet connection, insofar as it has a pressure drainage system interacts. The cover causes itself to be in the area the inlet chamber also has a radial flow for the inlet connector pressure drainage.

Nach einer vorteilhaften Weiterbildung der Erfindung umfasst die Abdeckung für die Druckentwässerung ebenfalls eine Scheibe, die unter einer Distanz zum Einlaufstutzen angeordnet ist. In Weiterbildung der Erfindung ist auf der Abdeckung ein Kiesfangkorb verrastbar.According to an advantageous development of the invention, the cover comprises for the pressure drainage also a disc, which is under a distance to the inlet nozzle is arranged. In further training of Invention, a gravel trap can be locked onto the cover.

Zwischen dem Kragenrand 3 von Einlaufkörper 2 und Losflansch 4 kann eine nicht näher dargestellte Anschlussfolie eingelassen werden, die zur dichtenden herstellenden Verbindung einer Dachschicht zwischen diesen verspannbar ist. Wie aus der Seitenansicht der Figur 01 aber auch der Figur 02 zu erkennen ist, weist der Einlaufkörper 2 eine Kammer 6 auf, in der zwei Ablaufrohre 7 und 8 münden, wobei das eine Ablaufrohr 7 mit einem Druckentwässerungssystem und das andere Ablaufrohr 8 mit einem Freispiegelentwässerungssystem zusammenwirkt.Figure 01 shows a side view of a device 1 for drainage of flat roofs. Balconies, terraces or other low-rise buildings. The device 1 consists of an inlet body 2 which a collar edge 3 is formed on in the inserted state a roof surface, not shown, rests and in which Inlet 2 a loose flange 4 can be inserted, which also has a collar edge 5 has.

As from the side view 01 but also 02 can be seen, the Inlet body 2 has a chamber 6 in which two drain pipes 7 and 8 open, the one drain pipe 7 with a pressure drainage system and the other drain pipe 8 with a free-level drainage system interacts.

    Wie aus der Figur 01 und 02 zu erkennen ist, weist die Einlaufkammer 6 im wesentlichen einen flach ausgebildeten Boden 9 auf. Dabei mündet das Ablaufrohr 7 mit seinem Einlaufstutzen 10 zur Druckentwässerung direkt in den Boden 9 der Einlaufkammer 6. Das Ablaufrohr 8, welches für die Freispiegelentwässerung bestimmt ist, ragt durch den Boden 9 hindurch, wobei sein Einlaufstutzen 11 oberhalb der Einlaufkammer 6 endet.
