Description

Die Erfindung betrifft eine Entwässerungsvorrichtung für Dächer nach dem Oberbegriff des beigefügten Anspruches 1.The invention relates to a drainage device for roofs according to the preamble of attached claim 1.

Aus dem Stand der Technik sind verschiedene Entwässerungsvorrichtungen bekannt, die insbesondere für die Entwässerung von Flachdächern verwendbar sind. Beispielsweise ist aus der DE-PS 34 45 186 ein Wassereinlauf für den genannten Zweck bekannt, der aus einem Einlaufkörper besteht, welcher an einen Kunststoffring und an eine Anschlussfolie derart angeschäumt ist, dass die Oberseite der Anschlussfolie und die obere Stirnfläche des Ringes einen planen Anschlussflansch bilden. Der Einlaufkörper ist im wesentlichen als zylindrisches Rohr ausgebildet und weist einen nach außen vorstehenden Kragen auf. Um einen derartigen Wassereinlauf bei Flachdächern unterschiedlicher Dicke einsetzen zu können, ist es bekannt, den Wassereinlauf in Verbindung mit einem Aufstockelement zu verwenden. Das Aufstockelement ist hierbei im wesentlichen gleich mit dem Einlaufkörper ausgebildet, wobei der Außendurchmesser des Aufstockelements mit dem Innendurchmesser des Einlaufkörpers übereinstimmt, so dass das Aufstockelement in den Einlaufkörper einschiebbar ist. Die Abdichtung zwischen dem Aufstockelement und dem Einlaufkörper erfolgt bei diesen vorbekannten Vorrichtungen durch einen O-Ring, der in eie innenliegende, umlaufende Nut in den Einlaufkörper eingesetzt ist. Die Anpassung dieser vorbekannten Entwässerungsvorrichtung an die Dicke des Daches erfolgt dadurch, dass das Aufstockelement mehr oder weniger in den Einlaufkörper eingeschoben wird. Es hat sich jedoch bei diesen vorbekannten Entwässerungsvorrichtungen als nachteilig ergeben, dass bei der Montage des Aufstockelements im Einlaufkörper und bei der Einstellung der relativen Position des Aufstockelementes zum Einlaufkörper Verschiebungen des O-Rings innerhalb des Einlaufkörpers auftreten, die die notwendige Abdichtung des Aufstockelementes relativ zum Einlaufkörper nachteilig beeinflussen. Darüber hinaus kann es zu einem Herausschieben des O-Rings aus der Nut kommen, so dass in diesem Bereich die Abdichtung in der voranstehend genannten Weise nicht mehr vollständig gegeben ist.Various dewatering devices are known from the prior art, which especially suitable for the drainage of flat roofs. For example from DE-PS 34 45 186 a water inlet for the purpose known, from an inlet body which is connected to a plastic ring and to a connection foil foamed so that the top of the terminal foil and the upper end face of the ring form a flat connection flange. The inlet body is essentially designed as a cylindrical tube and has an outwardly projecting collar. To use such a water inlet with flat roofs of different thickness It is known to be able to use the water inlet in conjunction with an extension element use. The extension element is in this case substantially equal to the inlet body formed, wherein the outer diameter of the Aufstockelements with the inner diameter of the inlet body, so that the Aufstockelement in the inlet body is insertable. The seal between the extension element and the inlet body takes place in these prior art devices by an O-ring, which is in internal, circumferential groove is inserted into the inlet body. The adaptation of this previously known dewatering device to the thickness of the roof takes place in that the Aufstockelement is more or less inserted into the inlet body. It has However, these are disadvantageous in these prior art dewatering devices, that during assembly of the Aufstockelements in the inlet body and in the setting of relative position of the extension element to the inlet body displacements of the O-ring occur within the inlet body, the necessary sealing of the Aufstockelementes affect adversely relative to the inlet body. In addition, it can become one Pushing out the O-ring come out of the groove, so that in this area the Seal in the above manner is no longer complete.

Eine bekannte Entwässerungsvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art - DE-A-37 37 767 - lehrt ein Trichtergüed, das mit einem rohrförmigen Stutzen weit in die Betondecke hineinragt und dort über eine Dichtung an der Dampfsperrschicht abschließt, hier unmittelbar an einem in der Betondecke angeordneten Formstück, an das die breitflächig zwischen der Betondecke und der darüber befindlichen Isolierschicht angeordnete Dampfsperrschicht angeschlossen ist.A known dewatering device referred to in the preamble of claim 1 Art - DE-A-37 37 767 - teaches a Trichtergüed that with a tubular neck in far the concrete ceiling protrudes and terminates there via a seal on the vapor barrier layer, here directly on a arranged in the concrete ceiling fitting, to which the broadly arranged between the concrete floor and the insulating layer located above it Vapor barrier layer is connected.

Des weiteren ist bei einem Dach anderen Aufbaus - DE-A-1 658 207 - bekannt, zwischen einem Dachaufnahmekörper und einer abdichtenden Folie einen elastischen Spreizkörper einzusetzen, der im Bereich des Dichtungsabschnittes elastische Dichtlippen aufweist, die zum oberen Ende des Aufnahmekörpers hin schräg gestellt sind und damit ein Herausfüesen der Folie aus dem Dichtungsabschnitt verhindern.Furthermore, in a roof of other construction - DE-A-1 658 207 - known between a roof receiving body and a sealing foil an elastic expansion body use, which has elastic sealing lips in the region of the sealing portion, the are inclined towards the upper end of the receiving body and thus a herausfüesen prevent the foil from the sealing portion.

Ausgehend von dem vorstehend beschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Entwässerungsvorrichtung zu schaffen, die einfach ausgestaltet und zu montieren ist sowie in zuverlässiger Weise verhindert, dass aufsteigender Wasserdampf zu Kondensationsbildung in der Wärmedämmung führt. Starting from the above-described prior art, the invention is the The object of the invention is to provide a generic dewatering device which is simple is designed and assembled in a reliable way prevents ascending Water vapor leads to condensation in the thermal insulation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Dampfsperrelement zwischen der Außenfläche des Einlaufkörpers und der dieser Außenfläche zugewandten Stirnseite der wärmedämmenden Dachschicht angeordnet ist, und dass die Dichtung zwischen der Außenfläche des Einlaufkörpers und dem Dampfisperrelement angeordnet ist und den Einlaufkörper in der Öffnung des Daches gegen Austreiben aus dieser Öffnung arretiert.This object is achieved in that the Vapor barrier element between the outer surface of the inlet body and the latter Outside surface facing front side of the heat-insulating roof layer is arranged, and that the seal between the outer surface of the Inlet body and the Dampfisperrelement is arranged and the inlet body locked in the opening of the roof against expulsion from this opening.

Bei der erfindungsgemäßen Entwässerungsvorrichtung ist demzufolge der trichterförmige Einlaufkörper unter Zwischenlage eines an die unterhalb der dämmenden Dachschicht angeordnete Dampfsperrschicht angeschlossenen Dampfsperrelementes in eine entsprechende Öffnung im Dach eingesetzt. Das Dampfsperrelement trennt hierbei die Dachisolierung von dem Einlaufkörper ab, so daß durch die Öffnung aufsteigende Feuchtigkeit nicht in die dämmende Dachschicht eindringen kann. An den Einlaufkörper ist innerhalb der Öffnung ein Aufsteckelement angeschlossen, und zwar durch Aufschieben auf den unteren, engeren Endbereich des trichterfömigen Einlaufkörpers oder mittels Verbindungsmuffe, die beide miteinander umschließend verbindet. Das Aufsteckelement kann das Ablaufrohr selbst sein, es kann sich aber auch um ein Zwischenrohrstück handeln. Darüberhinaus ist zwischen dem Einlaufkörper und dem Dampfsperrelement eine Dichtung angeordnet, mit der der Einlaufkörper an dem Dampfsperrelement und somit am Dach festgehalten ist. Die vorzugsweise ringförmig ausgebildete Dichtung sorgt dafür, daß eine Kondensationsbildung im Wärmedämmungsbereich des Daches verhindert wird und der Einlaufkörper in der Öffnung arretiert ist.In the dewatering device according to the invention is therefore the funnel-shaped inlet body with the interposition of a below the insulating roofing layer arranged vapor barrier layer connected Vapor barrier element in a corresponding opening in the roof used. The vapor barrier element separates In this case, the roof insulation from the inlet body, so that through the opening rising moisture can not penetrate into the insulating roof layer. A plug-in element is connected to the inlet body within the opening, by pushing on the lower, narrower end of the funnel-shaped inlet body or by means of coupling sleeve, both together enclosing connects. The Aufsteckelement can the drain pipe be yourself, but it can also be an intermediate pipe piece. Furthermore is a seal between the inlet body and the vapor barrier element arranged with the inlet body to the vapor barrier element and thus is held on the roof. The preferably annular seal ensures that a condensation formation in the thermal insulation of the Roof is prevented and the inlet body is locked in the opening.

Der Angriff der Dichtung an dem Einlaufkörper erfolgt in einem oberen, weiteren Bereich, der insbesondere etwa hohlzylindrisch ausgebildet ist. Dadurch ist der untere, engere Bereich des trichterförmigen Einlaufkörpers für ein diesen Bereich von außen umgreifendes Aufschieben eines Ablaufrohres (Fallrohres) oder Verlängerungsstückes als Aufsteckelement innerhalb der Öffnung im Dach entsprechend frei zugänglich.The attack of the seal on the inlet body takes place in a upper, wider region, which is formed in particular approximately hollow cylindrical. As a result, the lower, narrower region of the funnel-shaped inlet body for a pushing around a drainpipe enclosing this area from the outside (Downpipe) or extension piece as Aufsteckelement within the Opening in the roof accordingly freely accessible.

Die Dichtung kann mit einem Federstahlring versehen sein, der dichtend an dem Einlaufkörper, angreift. Dieser Federstahlring dient einerseits der Arretierung des Einlaufkörpers an dem Dampfsperrelement und andererseits als Dichtkörper, der die Funktion der Dichtung ergänzt bzw. ersetzt, da es auch möglich ist, daß die Dichtung lediglich aus dem Federstahlring besteht. In diesem Fall ist es vorteilhaft, den Federstahlring aus nichtrostendem Stahl herzustellen.The seal may be provided with a spring steel ring which sealingly against the Inlet body, attacks. This spring steel ring serves on the one hand the lock the inlet body to the vapor barrier element and on the other hand as a sealing body, which supplements or replaces the function of the seal, since it is also possible that the seal consists only of the spring steel ring. In this case it is advantageous to produce the spring steel ring made of stainless steel.

Bei einer Weiterbildung dieser Ausgestaltung hat es sich als vorteilhaft erwiesen, daß der Federstahlring und/oder die Dichtung widerhakenförmig ausgebildet ist bzw. sind und vorzugsweise mit einer an der Außenfläche des Einlaufkörpers angeordneten Verrastung zusammenwirkt bzw. -wirken. Diese Ausgestaltung hat insbesondere den Vorteil, daß eine weitergehende Verrastung zwischen Dichtung und Einlaufkörper vorhanden ist. Darüberhinaus ist es bei einer widerhakenförmigen Dichtung vorteilhaft, daß die einzelnen Widerhaken als Dichtlippen wirken, so daß eine verbesserte Abdichtung vorhanden ist.In a development of this embodiment, it has proved to be advantageous that the spring steel ring and / or the seal is barb-shaped and are and preferably arranged with a on the outer surface of the inlet body Locking cooperates or acts. This embodiment has in particular the advantage that a further locking between seal and inlet body is present. Moreover, it is in a barb-shaped Seal advantageous that the individual barbs as sealing lips act, so that an improved seal is present.

Vorzugsweise ist das Dampfsperrelement im Querschnitt seines Kreisringverlaufes etwa L-förmig ausgebildet, wobei der etwa vertikal verlaufende Schenkelbereich eine rohrförmige Auskleidung für zumindest einen Teilbereich der Dachdicke bildet, während der andere, von der Auskleidung etwa in horizontaler Ebene abstrebende Schenkelbereich an die Dampfsperrschicht an der Unterseite der dämmenden Dachschicht angeschlossen ist und gegebenenfalls mit der tragenden Dachschicht in fester Verbindung steht.Preferably, the vapor barrier element in the cross section of its circular ring course approximately L-shaped, wherein the approximately vertically extending leg region a tubular lining for at least a portion of the roof thickness forms, while the other, from the lining approximately in horizontal Level shearing leg area to the vapor barrier layer at the bottom the insulating roof layer is connected and optionally with the load-bearing Roof layer is firmly connected.

Das Dampfsperrelement kann im montierten Zustand mit seinem die Auskleidung bildenden Schenkelbereich nach oben von dem horizontalen Schenkelbereich abragend angeordnet sein, so daß die Auskleidung in den die dämmende Dachschicht durchgreifenden Öffnungsbereich hineinragt. Man könnte somit in Begriffsanalogie zum Aufstockelement von einem "Unterstockelement" sprechen. Man kommt daher mit einem als normaler Dachgully ausgebildeten "Aufstockelement" aus, um zusammen mit dem "Unterstockelement" eine anschlußfähige Entwässerungsvorrichtung zur Verfügung zu stellen.The vapor barrier element may be in the assembled state with its lining forming leg region up from the horizontal leg region be arranged projecting, so that the lining in the insulating roof layer penetrating opening area protrudes. One could thus be in conceptual analogy to the extension element of a "lower floor element" speak. One comes therefore with a trained as a normal roof gully "Aufstockelement" out, in order to connect with the "lower floor element" a connectable To provide drainage device.

Ein weiteres Merkmal der Erfindung ist darin zu sehen, daß das Dampfsperrelement in seinem dem Einlaufkörper zugewandten Bereich eine Ausnehmung für die Dichtung hat, die vorzugsweise im Querschnitt rechteckig ausgebildet ist. Diese Ausnehmung hat insbesondere die Aufgabe, die Dichtung bzw. den Federstahlring derart in dem Dampfsperrelement zu halten, daß beim Einsetzen des Einlaufkörpers in die Öffnung ein Verschieben oder ein Herauschieben der Dichtung aus dem Dampfsperrelement vermieden wird, so daß eine dauerhafte Abdichtung der erfindungsgemäßen Entwässerungsvorrichtung bei vereinfachter Montage gegeben ist.Another feature of the invention is the fact that the vapor barrier element in its the inlet body region facing a recess for the seal has, which is preferably rectangular in cross-section. This recess has in particular the task of the seal or the spring steel ring to hold in the vapor barrier element that at the onset of Intake body in the opening a move or a Herauschieben the seal is avoided from the vapor barrier element, so that a permanent seal the dewatering device according to the invention in simplified Assembly is given.

An der Unterfläche der Dachschicht ist in vorteilhafter Weise eine Verstärkungseinrichtung, insbesondere ein Verstärkungsblech, unter Zwischenlage eines Randbereiches des Dampfsperrelementes angeordnet, so daß dieses in diesem Bereich mit dem Dach bzw. einer tragenden Dachschicht verbunden ist. Das Dampfsperrelement ist darüberhinaus in vorteilhafter Weise mit der Verstärkungseinrichtung verbunden, vorzugsweise verschraubt und/oder verklebt; das gilt insbesondere für Trapezblechdecken als tragende Dachschicht.On the lower surface of the roof layer is advantageously an amplifying device, in particular a reinforcing plate, with the interposition of a Edge region of the vapor barrier element arranged so that this in this area is connected to the roof or a supporting roof layer. The Vapor barrier is also advantageously with the amplifying device connected, preferably screwed and / or glued; this is especially true for trapezoidal sheet metal ceilings as a supporting roof layer.

Bei der erfindungsgemäßen Entwässerungsvorrichtung ist es besonders vorteilhaft, daß die Dichtung bzw. der Federstahlring an dem Dampfsperrelement befestigt ist, so daß der Einlaufkörper relativ zu dem Dampfsperrelement in axialer Richtung verschoben werden kann. Hierdurch kann die erfindungsgemäße Entwässerungsvorrichtung in einfacher Weise in Abhängigkeit der axialen Länge des Einlaufkörpers an die jeweilige Gesamtdicke des Flachdaches angepasst werden.In the dewatering device according to the invention it is particularly advantageous that the seal or the spring steel ring attached to the vapor barrier element is, so that the inlet body relative to the vapor barrier element in the axial Direction can be moved. As a result, the dewatering device according to the invention in a simple manner depending on the axial length of Inlet body can be adapted to the respective total thickness of the flat roof.

Schließlich ist bei einer erfindungsgemäßen Entwässerungsvorrichtung vorgesehen, daß die Dichtung an ihrer dem Einsteckkörper zugewandten Seite eine Vielzahl von nach unten gerichteten Dichtungsfahnen hat, die an der Außenfläche des Einsteckkörpers dichtend anliegen. Diese Dichtungsfahnen erhöhen die Abdichtfunktion der Dichtung gegenüber dem Einsteckkörper.Finally, it is provided in a dewatering device according to the invention, that the seal on its side facing the male body a Variety of down-facing sealing flags on the outside surface abut the male body sealing. These sealing flags increase the Sealing function of the seal against the male body.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines in der Zeichnung in geschnitten dargestellter Halbseitenansicht wiedergegebenen Ausführungsbeispieles.Further features and advantages of the invention will become apparent from the following Description of a cut in the drawing in half-side view reproduced embodiment.

Ein zweiter Schenkel 12 des Dampfsperrelementes 10 bildet eine rohrförmige Auskleidung und weist an seinem freien Ende eine im Querschnitt U-förmige Abbiegung 13 auf, in welche eine Dichtung 14 eingesetzt ist, die mit ihrer Dichtfläche an der Außenfläche des Einlaufkörpers 6 anliegt, und zwar in einem oberen, etwa hohlkreiszylindrischen Abschnitt 21.On the dewatering device 5 facing end face 9 of the roof layer 2, a vapor barrier element 10 is arranged, which is annular and in the Cross-section is L-shaped. A leg 11 of the vapor barrier 10 is located on the opposite side of the film bottom of the roof layer 2 and is connected to a vapor barrier layer 20 disposed there. The connection can be carried out for example by a gluing process. A second Leg 12 of the vapor barrier element 10 forms a tubular lining and has at its free end a cross-sectionally U-shaped turn 13 in which a seal 14 is inserted, with its sealing surface on the Outer surface of the inlet body 6 rests, in an upper, approximately hollow circular cylindrical Section 21.

Die Dichtung 14, welche vorzugsweise aus einem Elastomer besteht, weist einen Federstahlring auf, der der Dichtung 14 eine ausreichende Stabilität verleiht und die Dichtung 14 beim Einschieben des Einlaufkörpers 6 in die Öffnung 4 in der durch die Abbiegung 13 gebildeten Ausnehmung des Dampfsperrelementes 10 hält.The seal 14, which preferably consists of an elastomer, has a Spring steel ring, which gives the seal 14 sufficient stability and the seal 14 during insertion of the inlet body 6 in the opening 4 in the formed by the bend 13 recess of the vapor barrier element 10th holds.

An der dem Einlaufkörper 6 zugewandten Seite der Dichtung 14, welche als Ringdichtung ausgebildet ist, sind mehrere Dichtfahnen nach unten ausgerichtet, d.h. in Richtung auf das Ende 8 des Einlaufkörpers 6, angeordnet. Diese Dichtfahnen wirken in Form von Widerhaken, welche an der Außenfläche des Einlaufkörpers 6 angreifen. Dort können Verrastungen vorgesehen sein, die mit den Dichtfahnen zusammenwirken, so daß ein Austreiben des Einlaufkörpers 6 aus der Öffnung 4 vermieden wird.At the inlet body 6 facing side of the seal 14, which as Ring seal is formed, a plurality of sealing flags are aligned downward, i.e. in the direction of the end 8 of the inlet body 6, arranged. These sealing flags act in the form of barbs, which on the outer surface of the inlet body 6 attack. There can be provided latching, which with the Dense flags interact, so that expelling the inlet body 6 from the opening 4 is avoided.

An das Ende 8 des Einlaufkörpers 6 ist ein Aufsteckelement 15 - gegebenenfalls direkt das obere Ende eines Fallrohres - angesetzt, welches als zylindrisches Rohr ausgebildet ist und an seinem einen Ende in seinem Innenbereich ein als radial ausgebildeter Vorsprung ausgebildetes Befestigungselement 16 tragen kann, das mit einer Befestigungsvorrichtung 17 an der Außenfläche des Endes 8 des Einlaufkörpers 6 zusammen wirken kann. In der Regel wird das Fallrohr bzw. Aufsteckelement in glatter Ausbildung auf das Ende 8 des Einlaufkörpers 6 dieses außen umgreifend aufgeschoben oder mittels einer beide benachbarten Ränder übergreifenden Muffe angeschlossen.At the end 8 of the inlet body 6 is a slip-15 - optionally directly the upper end of a downpipe - attached, which as a cylindrical Pipe is formed and at its one end in its interior as a radially trained projection trained fastener 16 wear can, with a fastening device 17 on the outer surface of the end eighth of the inlet body 6 can act together. In general, the downpipe or slip-on element in a smooth training on the end 8 of the inlet body. 6 this pushed around the outside or by means of a two adjacent Connected edges overlapping sleeve.

Die dargestellte Entwässerungsvorrichtung 5 kann bei Flachdächern 1 bzw. Dachschichten 2 mit unterschiedlichen Dicken verwendet werden, da eine Relativbewegung des Einlaufkörpers 6 zum Dampfsperrelement 10 möglich ist, ohne daß die wesentlichen Funktionen der Abdichtung zwischen Dampfsperrelement 10 und Einlaufkörper 6 sowie die Arretierung dieser beiden Elemente zueinander beeinträchtigt werden. Ausschlaggebend ist hierbei lediglich der axial verlaufende Teil des Einlaufkörpers 6.The illustrated dewatering device 5 can be used in flat roofs 1 and Roof layers 2 are used with different thicknesses, as a relative movement of the inlet body 6 to the vapor barrier element 10 is possible, without that the essential functions of sealing between vapor barrier element 10 and inlet body 6 and the locking of these two elements to each other be affected. Decisive here is only the axially extending Part of the inlet body 6.

Schließlich ist bei der dargestellten Entwässerungsvorrichtung 5 ein Verstärkungsblech 18 angeordnet, welches auf dem Schenkel 11 des Dampfsperrelementes 10 aufliegt und über eine Schraube 19 mit dem Dampfsperrelement 10 verbunden ist. Darüberhinaus ist es aber auch möglich, das Verstärkungsblech 18 mit dem Dampfsperrelement 10, nämlich dessen Schenkel 11, zu verkleben. In gleicher Weise ist eine Kombinationsverbindung aus Verklebetechnik und Schraubtechnik denkbar.Finally, in the illustrated dewatering device 5 is a reinforcing plate 18 is arranged, which on the leg 11 of the vapor barrier element 10 rests and a screw 19 with the vapor barrier element 10th connected is. Moreover, but it is also possible, the reinforcing plate 18th with the vapor barrier element 10, namely its legs 11, to glue. In the same way is a combination of adhesive bonding and Bolting conceivable.
