Abstract

1. Flat roof ventilator with an upper section (I), which has, at its free end, a head-piece with a larger cross-section and is arranged in a detachable overlapping connection on a lower pipe section (II), which is located on a support plate (1), which is to be fastened on the roof and serves as a support for the roof covering foil (11), and continues downwards in a down connection pipe (2), characterized in that a connecting sleeve (3), which projects upwards on the support plate (1) coaxially with the connection pipe (2), forms an external thread (9) for screwing on, with stop limiting, the upper pipe section (I), which external thread (9), starting from the free end of the connecting sleeve (3), only extends over a part of the length of the same and leaves a distance to the support plate (1) for the arrangement as a seal of a turned up collar (12) of the roof covering foil (11).

Description

Die Erfindung betrifft einen aus Oberteilrohr und Unterteil­rohr bestehenden Flachdachentlüfter mit einer im Abstand vom unteren Ende angeordneten, vom Entlüftungsrohr durchsetzten Stützplatte zur Auflage der Dacheindeckungsfolie und mit am oberen Ende des in Überlappung zum Unterteilrohr liegenden Oberteilrohr vorgesehenem querschnittsgrößeren Kopfstück.The invention relates to a flat roof vent consisting of an upper part pipe and a lower part pipe, with a support plate arranged at a distance from the lower end and penetrated by the ventilation pipe for supporting the roof covering film, and with a head section of larger cross section provided at the upper end of the upper pipe lying in overlap with the lower part pipe.

Die Zweiteiligkeit gattungsgemäßer Flachdachentlüfter wirkt sich beim Verlegen der Eindeckungsfolie hilfreich aus. Flachdachentlüfter dieser Art sind durch den Prospekt, "Sicherheit und Qualität für's Dach" der Anmelderin auch druckschriftlich verbreitet (Impressum 3/86/80 OC). Ober­rohr und Unterrohr sind auf eine Steckzuordnung abgestellt. So kann in günstiger Weise nach dem Verkleben der Dacheindek­kungsfolie praktisch als letztes das in der Regel ein quer­schnittsgrößeres Kopfstück aufweisende Oberteilrohr aufge­steckt werden. Es steht also im Zuge der Montagearbeiten nicht im Wege und wird andererseits auch nicht beschädigt. Außerdem kann ein geringerer Freischnitt zugrundeliegen, da die Folie nicht über den dicken Kopf gestülpt werden muß.The two-part generic flat roof vent has a helpful effect when laying the roofing membrane. Flat roof ventilators of this type are also distributed in printed form by the applicant's brochure, "Safety and Quality for the Roof" (Imprint 3/86/80 OC). The top tube and down tube are assigned to a plug-in assignment. Thus, after the roof covering film has been glued, the top tube, which generally has a head section with a larger cross-section, can practically be slipped on last. So it is not in the way of the assembly work and on the other hand it is not damaged. It can also be based on a smaller free cut, since the film does not have to be put over the thick head.

Aufgabe der Erfindung ist es, einen gattungsgemäßen Flach­dachentlüfter ohne Vergrößerung der Teilezahl noch zuord­nungsgünstiger auszubilden, dies unter Zugewinn an Gebrauchs­stabilität.The object of the invention is to design a generic flat roof vent without increasing the number of parts even easier to assign, this with increased stability in use.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilhafte Weiterbildungen des erfindungsgemäßen Flachdachentlüfters.The subclaims are advantageous developments of the flat roof vent according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßer Flach­dachentlüfter von insbesondere erhöhtem Gebrauchswert er­zielt: Die Schraubverbindung führt zu einem belastungsstabi­len Verbund, dies selbst auch dann, wenn nur ein Teil des Gewindes im Eingriff steht, was z. B. dann vorkommt, wenn unterschiedliche Längen der im Durchtrittsbereich kragenar­tig hochgestülpten Eindeckungsfolie kompensiert werden müs­sen. Die enge Nachbarschaftslage der Schraubverbindungsstel­le zur Stützplatte bringt eine sich gegenseitig hochstabili­sierende Zone; die Schraubkräfte und die bspw. bei vollem Durchlaufen des Gewindeabschnitts auftretende Torsionswir­kung bringen, trotz der Möglichkeit der Anwendung recht geringer Wandungsdicken, kein Problem. Auch das etwaige spätere Lösen, um bspw. ein anderes Kopfstück aufzusetzen, wie z. B. einen Haubenkorb, eine Antennendurchführung, eine schlagregensichere Haube etc., ist jederzeit ohne weiteres möglich. Eine vor allem auch witterungsgünstige Ausgestal­tung der Schraubenverbindungsstelle ergibt sich dadurch, daß das Oberteilrohr mit seinem aufgeweiteten, unteren Ende das Schraub-Mutternteil bildet. Abfließender Regen kann somit nicht in die Verbindungsstelle eintreten. In diesem Zusam­menhang ergibt sich eine vorteilhafte Ausgestaltung weiter durch eine vom aufgeweiteten Ende abwärts ragende Ringschür­ze, die ausladend über die Randkante des Kragens der Dachein­deckungsfolie tritt. Dies stellt eine ebenso einfache, wie wirkungsvolle Dichtungsmaßnahme im kritischen Bereich der Durchtrittsstelle des Entlüftungsrohres dar. Optimiert ist diese Lösung durch einen Überlappungsfreiraum zwischen Schür­ze und Mantelfläche des Unterteilrohres. Die Ringschürze ist so in Art einer Glocke gestaltet, deren Rand einen Schutzmantel formt, andererseits aber zufolge des Freiraumes ein schnelles Abtrocknen des Kragens sicherstellt und das Eindrücken von bspw. Faserkitt zu Dichtungszwecken erlaubt.As a result of such a design, a generic flat roof vent of particularly high utility value is achieved: the screw connection leads to a load-stable bond, even if only part of the thread is engaged, which, for. B. occurs when different lengths of the covering film which is turned up like a collar in the passage area have to be compensated for. The close proximity of the screw connection point to the support plate creates a mutually highly stabilizing zone; the screwing forces and the torsional effect that occurs, for example, when the threaded section is fully run through, despite the possibility of using very small wall thicknesses, pose no problem. Also possible later loosening, for example, to put on another head piece, such as. B. a hood basket, an antenna feedthrough, a driving rain-proof hood, etc., is easily possible at any time. A particularly favorable weather-related configuration of the screw connection point results from the fact that the upper part tube forms the screw nut part with its widened, lower end. Flowing rain cannot enter the connection point. In this context, an advantageous embodiment is further provided by a ring apron protruding downwards from the widened end, which protrudes over the edge of the collar of the roof covering film. This represents an equally simple and effective sealing measure in the critical area of the passage point of the ventilation pipe. This solution is optimized by an overlap space between the apron and the outer surface of the lower part pipe. The ring apron is designed in the manner of a bell, the edge of which forms a protective jacket, but on the other hand due to the free space ensures that the collar dries quickly and allows, for example, fiber cement to be pressed in for sealing purposes.

Der Gegenstand der Erfindung ist nachstehend anhand eines zeichnerisch veranschaulichten Ausführungsbeispieles näher erläutert. Es zeigt

  • Fig. 1 den erfindungsgemäß ausgebildeten Flachdachentlüf­ter in Seitenansicht, und zwar in verschraubtem Zustand,
  • Fig. 2 denselben im Vertikalschnitt, in unverschraubtem Zustand,
  • Fig. 3 die Draufsicht auf das Unterteilrohr mit angeform­ter Stützplatte und
  • Fig. 4 eine Herausvergrößerung aus Fig. 1, also in ver­schraubtem Zustand.
The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment. It shows
  • 1 is a side view of the flat roof vent according to the invention, in the screwed state,
  • 2 the same in vertical section, in unscrewed condition,
  • Fig. 3 is a plan view of the lower tube with molded support plate and
  • Fig. 4 is an enlargement of Fig. 1, that is, in the screwed state.

Der dargestellte Flachdachentlüfter besteht aus einem Ober­teilrohr I und einem Unterteilrohr II. Es handelt sich um Kunststoff-Spritzteile.The flat roof vent shown consists of an upper pipe I and a lower pipe II. These are injection molded plastic parts.

Dem Unterteilrohr II ist außenseitig verlaufend eine flansch­artige Stützplatte 1 angeformt. Letztere erstreckt sich in einer Senkrechtebene zur Mittelachse x-x des Flachdachentlüf­ters, also horizontal. Sie ist als Ringscheibe gestaltet mit oberseitig gefaster Randkante.A flange-like support plate 1 is integrally formed on the outside of the lower pipe II. The latter extends in a vertical plane to the central axis x-x of the flat roof vent, i.e. horizontally. It is designed as a ring disc with a bevelled edge on the top.

Der axiale Stützplatten-Abstand zum unteren Ende 2 des Unter­teilrohres II ist größer als der entsprechende Abstand zum oberseitigen Ende des Unterteilrohres II.The axial support plate distance to the lower end 2 of the lower part pipe II is greater than the corresponding distance to the upper end of the lower part pipe II.

Dieses oberseitige Ende trägt das Bezugszeichen 3. Der Durchmesser der Stützplatte 1 entspricht etwa dem drei- bis vierfachen Durchmesser des Unterteilrohres II.This upper end has the reference number 3. The diameter of the support plate 1 corresponds approximately to three to four times the diameter of the lower pipe II.

Die Stützplatte 1 weist in geringem Abstand zur Peripherie lochartige Durchbrechungen 4 auf zum Durchtritt nicht mehr dargestellter Befestigungsmittel, die die Verbindung des Unterteilrohres II mit der Flachdachkonstruktion 5 sichern. Auf deren Oberseite stützt sich die Stützplatte 1 ab. Zum Durchtritt des Unterteilrohres II weist die Flachdachkon­struktion 5 eine vorzugsweise querschnittsangepaßte Vertikal­bohrung 6 auf. Die Durchbrechungen 4 sind in gleichem Win­kel beabstandet. Insgesamt befinden sich acht Durchbrechun­gen 4 in der Stützplatte 1.The support plate 1 has, at a short distance from the periphery, hole-like openings 4 for the passage, not shown, fastening means which secure the connection of the lower pipe II to the flat roof structure 5. The support plate 1 is supported on the upper side thereof. For the passage of the lower pipe II, the flat roof construction 5 has a vertical bore 6, preferably adapted to the cross section. The openings 4 are spaced at the same angle. There are a total of eight openings 4 in the support plate 1.

Das Oberteilrohr I befindet sich in Überlappung zum Unter­teilrohr II. Diese Überlappung von Oberteilrohr I und Unter­teilrohr II ist als kurz oberhalb der Stützplatte 1 angeord­nete Schraubverbindungsstelle SV realisiert.The upper part pipe I is in overlap with the lower part pipe II. This overlap of the upper part pipe I and lower part pipe II is realized as a screw connection point SV arranged just above the support plate 1.

Das Innengewinde 7 des Oberteilrohres I befindet sich im aufgeweiteten, unteren Ende 8. Es bildet das Schraub-Mut­ternteil. Der periphere Versprung hält sich im Maß der Dicke der Rohrwandung.The internal thread 7 of the top tube I is in the widened, lower end 8. It forms the screw nut part. The peripheral jump is in line with the thickness of the pipe wall.

Das entsprechende Außengewinde 9 liegt in einer inversen Versprungzone 10 des oberen Endes 3 des Unterteilrohres II. Die entsprechenden Aufweitungen bzw. Verdickungen schaffen einerseits stabilisierte Gewindeeingriffszonen, und bringen andererseits aber wegen des nur geringen Vorsprungs keinen Nachteil in strömungstechnischer Hinsicht. Die axiale Länge der Gewinde 7/9 entspricht etwa einem Fünftel des maximalen lichten Rohrdurchmessers von Oberteilrohr I bzw. Unterteil­rohr II.The corresponding external thread 9 lies in an inverse jump zone 10 of the upper end 3 of the lower part pipe II. The corresponding widenings or thickenings on the one hand create stabilized thread engagement zones, but on the other hand bring no disadvantage in terms of flow technology because of the small projection. The axial length of the threads 7/9 corresponds to approximately one fifth of the maximum clear pipe diameter of the upper pipe I or lower pipe II.

Das aufgeweitete bzw. verdichtete Ende 8 kann eine Axial­riefung aufweisen, dies zur Erhöhung der Griffigkeit und damit Erleichterung der Schraubzuordnung bzw. des Abschrau­bens. Durch Mehrkantigkeit können auch Voraussetzungen geschaffen werden für das Ansetzen eines Maulschlüssels.The widened or compressed end 8 can have an axial grooving, this to increase the grip and thus facilitate screwing or unscrewing. By polygonal conditions can also be created for the application of a wrench.

Sämtliche Übergangskanten der gewindebildenden Abschnitte sind gefast.All transition edges of the thread-forming sections are chamfered.

Die Zuordnung ist wie folgt:The assignment is as follows:

Nach Befestigen des Unterteilrohres II wird die Dacheindek­kungsfolie 11 übergelegt. Zum Übergreifen des stutzenartig über die Stützplatte 1 nach oben vorragenden Endes 3 des Unterteilrohres II bedarf es des Ausschneidens der Folie bzw. einer Kreuzschlitzung. Dabei ist darauf zu achten, daß noch ein genügender Vorrat zur Bildung eines hochschlagbaren Kragens 12 verbleibt, vergl. Fig. 4. Dieser Kragen 12 schmiegt sich eng in die Ringkehle zwischen Stützplatte 1 und dortiger Mantelwand des Unterteilrohres II. Der Kragen kann in üblicher Weise daran verklebt werden, so daß diese kritische Zone festgelegt ist.After attaching the lower pipe II, the roof covering film 11 is considered. To overlap the end 3 of the lower part pipe II projecting upward like a nozzle over the support plate 1, it is necessary to cut out the film or a cross-slit. Care should be taken to ensure that there is still sufficient stock to form a flip-up collar 12, see FIG. 4. This collar 12 nestles tightly into the ring groove between the support plate 1 and the lateral wall of the lower tube II there. The collar can be made in the usual manner be glued to it so that this critical zone is defined.

Es folgt danach das Aufschrauben des an seinem oberen Ende ein querschnittsgrößeres Kopfstück 13 aufweisenden Oberteil­rohres I. Beim Ausführungsbeispiel handelt es sich um eine nicht schlagregensichere Haube, die eine Anzahl horizonta­ler, axial beabstandeter Ringlamellen 14 aufweist und ober­seitig mit einem flachkegelförmigen Dach 15 abschließt. Wie ersichtlich, überragen die Ringlamellen 14 und der Dachrand die Mantelwand des Oberteilrohres I. Zufolge der Zweiteilig­keit kann das Oberteilrohr I nach Abschluß der Eindeckungsar­beiten aufgesetzt bzw. später jederzeit bequem ausgewechselt werden.This is followed by screwing on the upper part tube I, which has a head section 13 of larger cross-section at its upper end. The exemplary embodiment is a non-driving rain-proof hood which has a number of horizontal, axially spaced-apart annular fins 14 and ends on the top side with a flat-conical roof 15. As can be seen, the ring lamellae 14 and the roof edge protrude from the outer wall of the top tube I. Due to the two-part structure, the top tube I can be put on after the roofing work has been completed or can be easily replaced at any time later.

Um dem Oberteilrohr I noch eine weitgehendere Funktion zu verleihen, ist diesbezüglich so vorgegangen, daß vom aufge­weiteten Ende 8 eine abwärtsragende Ringschürze 16 ausgeht, die in rotationssymmetrischer Ausgestaltung ausladend über die obere Randkante 12ʹ des Kragens 12 der Dacheindeckungsfo­lie 11 tritt. An der Außenseite des Flachdachentlüfters ablaufendes Regenwasser kann so nicht in die Fuge zwischen Kragen 12 und Mantelwand des Unterteilrohres II eindringen.In order to give the top tube I a more extensive function, in this regard the procedure is such that a flared ring apron 16 extends from the widened end 8, which, in a rotationally symmetrical configuration, extends over the upper edge 12 'of the collar 12 of the roof covering film 11. Rainwater running off on the outside of the flat roof vent cannot penetrate into the joint between the collar 12 and the jacket wall of the lower pipe II.

Vielmehr erstreckt sich diese Kragenzone in einen Überlap­pungs-Freiraum 17 zwischen der Ringschürze 16 und der dorti­gen Mantelfläche des Unterteilrohres II. Der Überlappungs-­Freiraum kann in der dargestellten Weise unten offenbleiben oder bedarfsweise auch zugekittet werden, um z. B. deflek­tierten Schlagregen abzuhalten.Rather, this collar zone extends into an overlap free space 17 between the ring apron 16 and the lateral surface of the lower tube II there. The overlap free space can remain open in the manner shown below or, if necessary, can also be cemented in order, for. B. to prevent deflected driving rain.

Eine entsprechende glockenartige Ringschürze 16 läßt sich gleich mitanformen durch einen weiteren Aufweitungsschritt des im Grunde zylindrischen Rohrkörpers des Oberteilrohres I.A corresponding bell-like ring apron 16 can be molded at the same time by a further expansion step of the basically cylindrical tube body of the upper part tube I.

Unter Einsatz zäh-elastischen Materiales besitzt die Ring­schürze 16 auch eine gewisse Anpassungsfähigkeit an nicht gleichförmige Kragenzonenabschnitte. Ansonsten wirkt die Ringschürze 16 aber auch lagezentrierend; sie stellt eine Art Fangtrichter dar für das nach dem Aufsetzen auf das Unterteilrohr II stattfindende Verschrauben. Die Ringschür­ze 16 ist in strichpunktierter Linienart wiedergegeben.Using tough-elastic material, the ring apron 16 also has a certain adaptability to non-uniform collar zone sections. Otherwise, the ring apron 16 also acts in a position-centering manner; it represents a kind of catch funnel for the screwing which takes place after being placed on the lower pipe II. The ring apron 16 is shown in dash-dotted lines.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
