Description

Die Erfindung bezieht sich auf eine Dacheindeckungsplatte gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a roofing panel according to the preamble of claim 1.

Eine Dacheindeckungsplatte dieser Art ist durch die DE-A 2 128 035 bekannt. Diese Dacheindeckungsplatte weist im Mittelbereich eine Lüftungsöffnung auf. Letztere wird von einem ringsumlaufenden, zur Dacheindeckungsplatten-Oberseite weisenden Randkragen begrenzt. Überfangen ist die Lüftungsöffnung durch einen haubenartigen Deckel. Letzterer besteht aus gestaffelt übereinander liegenden Lamellenstreifen. Die Oberseite des Deckels ist entweder geschlossen oder gegittert. An der Unterseite der Dacheindeckungsplatte sitzt eine dem Umrißverlauf des Randkragens folgende Schale. Diese ist trichterförmig ausgebildet. An tiefster Stelle setzt ein Schlauchanschlußstutzen an, der mit einer Entlüftungsleitung verbunden werden kann. Die Schale ist verzerrt kegelförmiger Gestalt und etwa tropfenförmigen Grundrisses. Zur Befestigung der Schale greift diese mit einen Kragen durch die Lüftungsöffnung hindurch, um hinter eine Schulter des Deckels zu fassen. Eine solche Ausgestaltung ist fertigungstechnisch relativ kompliziert sowie montageungünstig. Die pagodendachartige Lamellenstruktur des Deckels bringt bei einstückiger Herstellung komplizierte Hinterschneidungsformen.A roof covering plate of this type is known from DE-A 2 128 035. This roof covering plate has a ventilation opening in the central area. The latter is bordered by a circumferential collar facing the top of the roofing slab. The ventilation opening is covered by a hood-like cover. The latter consists of staggered lamella strips. The top of the lid is either closed or grated. On the underside of the roof covering plate sits a shell that follows the outline of the edge collar. This is funnel-shaped. At the lowest point there is a hose connector that can be connected to a ventilation line. The bowl has a distorted conical shape and an approximately teardrop-shaped outline. To fasten the bowl, it reaches through the ventilation opening with a collar to reach behind a shoulder of the cover. Such an embodiment is relatively complicated in terms of production technology and is unsuitable for assembly. The pagoda-roof-like lamellar structure of the cover brings with it one-piece manufacture complicated undercut shapes.

Durch die US-A 3 374 138 ist eine Dacheindeckungsplatte bekannt, welche von einem ihr gleich mitangeformten Rohrstutzen durchsetzt ist, welcher also mit je einem Stutzenabschnitt die Dacheindeckungsplatten-Oberseite wie -Unterseite überragt. An den der Dacheindeckungsplatten- Unterseite angeformten Stutzen wird unter Vermittlung einer Klemmschelle ein Krümmmer befestigt, der wiederum mit einer Entlüftungsleitung, ebenfalls unter Verwendung einer Schelle, verbunden ist.A roof covering plate is known from US Pat. No. 3,374,138, which is penetrated by a pipe socket which is also molded onto it, and which therefore projects above and below the roof covering plate with a respective nozzle section. A manifold is attached to the nozzle formed on the underside of the roofing panel by means of a clamp, which in turn is connected to a ventilation line, also using a clamp.

Aufgabe der Erfindung es, eine gattungsgemäße Dacheindekkungsplatte in herstellungstechnisch einfacher, montagegünstiger Ausgestaltung so auszubilden, daß die Strömungsverhältnisse optimiert sind.The object of the invention is to design a generic roofing plate in a production-technically simple, easy-to-assemble configuration so that the flow conditions are optimized.

Gelöst ist diese Aufgabe durch die im Kennzeichen des Patentanspruchs 1 angegebene Erfindung.This object is achieved by the invention specified in the characterizing part of patent claim 1.

Der Unteranspruch ist eine vorteilhafte Weiterbildung der erfindungsgemäßen Dacheindeckungsplatte.The subclaim is an advantageous further development of the roof covering plate according to the invention.

Zufolge solcher Ausgestaltung ist eine gattungsgemäße Dacheindeckungsplatte erhöhten Gebrauchswerts erzielt: Der Randkragen setzt sich über die Dacheindeckungsplatten-Unterseite hinaus fort. Dies führt nicht nur zu einer Stabilisierung der Randzone der Luftdurchtrittsöffnung - es entsteht ein umlaufendes T-Profil -, sondern der Randkragen kann zugleich als Träger für die anzubringende Schale dienen. Die diesbezügliche Zweiteiligkeit öffnet eine praxisbezogen äußerst vorteilhafte Variabilität, dies sowohl in Bezug auf die Ausrichtung der Schale als auch in Bezug auf die Verwendung der unterschiedlichsten Schalentypen in Bezug auf Durchmesser und Lage des angeformten Schlauchanschlußstutzens. Vor allem Sonderformen finden eine günstige Zuordbarkeit. Aber auch in gesamtstabilisatorischer Hinsicht sind wesentliche Vorteile erzielt. Konkret ist so vorgegangen, daß der auch über die Unterseite der Dacheindekkungsplatte überstehende Randkragen mit seinen querverlaufenden Abschnitten die Innenkehlen einer Querwölbung der Dacheindeckungsplatte kreuzend schließt und, wie schon angedeutet, Träger der Überlappung aufgesteckten Schale ist, welche weiter den Schlauchanschlußstützen in Gegenüberlage zu einer Bogenlinie der Innenfläche des Deckels trägt dargestellt, daß er die Mitte des Bodens der Schale tangiert. Das entsprechende Ausfüllen der Innenkehlen verschließt nicht nur Strömungs-Nebenwege, die einen Eintritt der Entlüftungsluft bspw. zwischen Dachhaut und Dacheindeckungsplattenunterseite zuließen, sondern verleihen dem Randkragen einen homogenen stabilen Übergangsbereich zum Plattenkörper der Dacheindekkungsplatte. Dementsprechend kann auch eine hochgradige Dünnwandigkeit zugrundeliegen, was aus materialsparenden Gründen heute durchaus wieder Bedeutung hat. Aber auch in anderer strömungstechnischer Hinsicht liegen Vorteile vor, indem die im Mittelbereich der Dacheindeckungsplatte liegende erhabene Wölbung der haubenartigen Decke des Deckels nicht nur die dadurch auch noch vergrößerte Zwischenkammer der Schale begrenzt, sondern zugleich auch als Verteiler wirkt. Die aufsteigende Luftströmung prallt gegen diesen erhaben gewölbten Mittelbereich des Deckels und verteilt sich unter Umlenkung quer nach außen. Der Austausch über die Dacheindeckungsplatte ist so verbessert. Der die Mitte des Bodens der Schale tangierende Schlauchanschlußstutzen läßt sich durch Umsetzen der Schale den jeweils vorliegenden Gegebenheiten gerechtwerdend anbringen. In stabilisatorischer Hinsicht im Hinblick auf die Schale selbst erweist es sich schließlich noch als vorteilhaft, daß der Boden der Schale sich zum Schlauchanschlußstutzen hin in flach-pyramidaler Gestalt trichterförmig vertieft.As a result of such an embodiment, a generic roof covering plate of increased utility value is achieved: the edge collar continues beyond the underside of the roof covering plate. This not only stabilizes the edge zone of the air passage opening - a circumferential T-profile is created - but the edge collar can also serve as a carrier for the shell to be attached. The two-part system in this respect opens up a variability which is extremely advantageous in practice, both in relation to the orientation of the shell and in relation to the use of a wide variety of shell types with regard to the diameter and position of the molded hose connection piece. Special forms in particular are easy to assign. But there are also significant advantages in terms of overall stabilization. Specifically, the procedure is such that the edge collar, which also projects beyond the underside of the roof covering plate, closes with its transverse sections and intersects the inner throats of a transverse curvature of the roof covering plate and, as already indicated, is the carrier of the overlapping attached shell, which furthermore the hose connection supports in opposition to an arched line of the The inner surface of the lid shows that it touches the center of the bottom of the bowl. The corresponding filling of the inner fillets not only closes by-pass paths that allow the ventilation air to enter, e.g. between the roof skin and the underside of the roof covering, but also gives the edge collar a homogeneous, stable transition area to the plate body of the roof covering plate. Accordingly, a high degree of thin-walledness can also be the basis, which is of great importance again today for material-saving reasons. But there are also advantages in other fluid-technical terms in that the raised curvature of the hood-like cover of the cover, which lies in the middle region of the roof covering plate, not only limits the intermediate chamber of the shell which is thereby enlarged, but also acts as a distributor. The rising air flow impinges against this raised, arched central area of the lid and is distributed transversely outwards under deflection. The exchange over the roof covering plate is improved. The hose connection piece tangent to the middle of the bottom of the shell can be attached by moving the shell to meet the prevailing circumstances. In terms of stabilization with regard to the shell itself, it finally proves advantageous that the bottom of the shell deepens in a funnel shape in a flat, pyramidal shape towards the hose connector.

Die dreieckigen Pyramidenflächen können günstigst an den rechteckigen bzw. quadratischen Grundriß der Schale anschließen.The triangular pyramid surfaces can most conveniently connect to the rectangular or square floor plan of the bowl.

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

The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment. It shows:
  • 1 is a top view of the roof covering plate designed according to the invention,
  • 2 is a side view of this,
  • 3 shows the bottom view of the roof covering plate,
  • 4 shows the end view of the roof covering plate, seen from the ridge side,
  • Fig. 5 shows the section along line VV in Fig. 3, in comparison with Fig. 3 enlarged and
  • Fig. 6 shows the section according to Fig. VI-VI in Fig. 3, also enlarged.

Die Dacheindeckungsplatte weist in ihrem erhaben gewölbten Mittelbereich M eine Lüftungsöffnung 1 auf. Letztere ist rechteckigen Grundrisses. Die längeren Öffnungsrandkanten erstrecken sich in der Dacheindeckungsplatten-Neigungsrichtung.The roof covering plate has a ventilation opening 1 in its raised, arched central region M. The latter is rectangular in plan. The longer edges of the opening extend in the roofing sloping direction.

Die Lüftungsöffnung 1 ist durch einen aufwärts gerichteten Randkragen K begrenzt. Letzterer erstreckt sich ringsumverlaufend und bildet praktisch einen Schacht. Die Oberkante 2' beider in Querrichtung, d.h. parallel zur Traufe verlaufenden Kragenabschnitte 2 nimmt einen Verlauf, der dem des gewölbten Mittelbereichs M der Dacheindekkungsplatte entspricht, ein. Unter Belassung eines allseitigen Luftdurchtrittsschlitzes 3 verlaufen auch die darüber liegenden Innenflächen 4' eines die Luftdurchtrittsöffnung 1 überfangenden Deckels 4 gewölbt. Die Bogenlinien der Innenflächen 4' können in ihrem Querwölbungsmuster so gestaltet sein, daß die Oberkanten 2' der Kragenabschnitte 2 parallel zu den Innenflächen 4' verlaufen.The ventilation opening 1 is delimited by an upwardly directed edge collar K. The latter extends all around and practically forms a shaft. The top edge 2 'of both in the transverse direction, i.e. Collar sections 2 running parallel to the eaves take a course which corresponds to that of the curved central region M of the roof covering plate. Leaving an air passage slit 3 on all sides, the inner surfaces 4 ′ of a cover 4 that overlaps the air passage opening 1 also run arched. The curved lines of the inner surfaces 4 'can be designed in their transverse curvature pattern so that the upper edges 2' of the collar sections 2 run parallel to the inner surfaces 4 '.

Der ebenfalls rechteckigen Umriß aufweisende Deckel 4 geht in eine umlaufend angeordnete, abwärts gerichtete Randleiste 5 über. Randleiste 5 und Randkragen K überlappen einander (vergl. Fig. 6), so daß der Lüftungsstrom im Bereich des Luftdurchtrittsschlitzes 3 einen Z-förmigen Verlauf 6 nimmt. Die Spaltbreite zwischen der Randleiste 5 und dem Randkragen K entspricht in etwa der Spaltbreite zwischen Oberkante 2' und Innenfläche 4' der Abdeckhaube 4.The cover 4, which also has a rectangular outline, merges into a circumferentially arranged, downward-facing edge strip 5. Edge strip 5 and edge collar K overlap one another (see FIG. 6), so that the ventilation flow in the area of the air passage slot 3 takes a Z-shaped course 6. The gap width between the edge strip 5 and the edge collar K corresponds approximately to the gap width between the upper edge 2 'and the inner surface 4' of the cover 4.

Der firstseitige Abschnitt 5' der Randleiste 5 reicht bis auf die oberseitige Breitfläche der Dacheindeckungsplatte. Die Randleisten-Unterkante 5" ist dort dem Dacheindeckungsplatten-Wölbungsverlauf angepaßt. Der diesbezügliche Abschnitt ist dachfirstseitig etwas ausgestellt. Der tiefgezogene Abschnitt 5' der Randleiste 5 bildet einen Schurz, so daß abfließendes Regenwasser abgehalten wird, bzw. am Randkragen K nicht überschwappen kann. Von dort her besteht forglich auch kein direkter Luftein- bzw. Austritt. Dieser erfolgt vielmehr von den Längsseiten und der Traufseite her.The ridge-side section 5 'of the edge strip 5 extends to the wide top surface of the roof covering plate. The lower edge strip 5 "there is adapted to the roof covering plate curvature. The relevant section is somewhat exposed on the ridge side. The deep-drawn section 5 'of the edge strip 5 forms an apron so that rainwater flowing off is prevented or cannot overflow at the edge collar K. There is no direct air inlet or outlet from there, but rather from the long sides and the eaves side.

Zur Befestigung des haubenartigen Deckels 4 an der Dacheindeckungsplatte dienen von dessen Innenseite her ausgehende, freistehend angespritzte Zungen 7. Es sind insgesamt vier solcher Zungen 7 vorgesehen. Letztere besitzen winkelförmigen Querschnitt. Ihre einsteckenden Enden liegen mit ihren Außenseiten an den Innenecken des Randkragens K an. Sie sind im Bereich ihrer Innenecken mit dem Haltekragen verklebt, verrastet oder dergleichen. Den Steck-Begrenzungsanschlag bildet firstseitig den schurzartig bis auf die Oberseite der Dacheindeckungsplatte heruntergezogene Randleisten-Abschnitt 5'. Traufenseitig übernimmt diese Abstützung unter Freihaltung des Luftdurchtrittsschlitzes 3 je ein auf dem Rücken der Zunge 7 angeordneter Distanzsteg 8.To fasten the hood-like cover 4 to the roofing panel, freestanding molded tongues 7 are used which extend from the inside thereof. A total of four such tongues 7 are provided. The latter have an angular cross section. Their inserting ends lie with their outer sides on the inner corners of the edge collar K. They are glued, locked or the like in the area of their inner corners with the retaining collar. The plug-in limit stop on the ridge side is formed by the skirting section 5 'which is pulled down like a skirt to the top of the roofing panel. On the eaves side, this support takes over a spacer web 8 arranged on the back of the tongue 7 while keeping the air passage slot 3 free.

Der Randkragen K setzt sich über die Dacheindeckungsplatten-Unterseite hinaus fort, wo er in eine Schale Sch übergeht, an deren Boden ein nach unten gerichteter Schlauchanschlußstutzen 10 vorsteht. Letzterer weist kreisrunden Querschnitt auf und dient zum Aufstecken eines Entlüftungsschlauches 11 (vergl. Fig. 5).The edge collar K continues beyond the roof covering plate underside, where it merges into a shell Sch, on the bottom of which a downwardly directed hose connection piece 10 protrudes. The latter has a circular cross section and is used to attach a ventilation hose 11 (see FIG. 5).

Der Entlüftungsschlauch 11 ist als flexibler Schlauch gestaltet und geht von einer nicht näher dargestellten Entlüftungsleitung aus, mit welcher er ebenfalls in Wege der Steckverbindung gekuppelt ist.The ventilation hose 11 is designed as a flexible hose and is based on a ventilation line, not shown, with which it is also coupled by way of the plug connection.

Der verlängerte, die Unterseite U deutlich überragende Randragenabschnitt K' kann mit der Schale plus Schlauchanschlußstutzen 10 einstückig der Dacheindeckungsplatte angeformt sein. Für eine Zugänglichkeit oder überhaupt die wahlweise Bestückung ist das dargestellte Ausführungsbeispiel jedoch so realisiert, daß der Randkragen K als die Halterung der als getrenntes Bauteil gestalteten Schale Sch ausgebildet ist. Hierzu ist eine Steckverbindung dahingehend gewählt, daß die Seitenwand 12 der Schale Sch formpassend und somit dichtend in Überlappung zum Randkragen K, genauer zum Randkragenabschnitt K' liegt. Es ist ein außenseitiger Übergriff der Schale vorgesehen. Seitenwand 12 und Randkragenabschnitt K' sind mittels sich kreuzender Schrauben 13 miteinander verbunden. Die diesbezüglichen Befestigungszonen liegen in den Endbereichen der Ecken. Die Durchtrittslöcher für gegebenenfalls selbstschneidend ausgebildeten Schrauben 13 liegen im gleichen Abstand von diesen Eckbereichen, so daß die Schale Sch wahlweise um 180° verschwenkt zugeordnet werden kann. Dies hat im Hinblick auf die außermittige, d.h. exzentrische Anordnung des Schlauchanschlußstutzens 10 an der Schale Sch den Vorteil, daß für diesen Stutzen eine mehr firstseitige bzw. eine mehr traufenseitige Lage erreicht wird. Man kann so im Wege stehenden Lattungen bzw. Sparren gut umgehen. Im Falle einer eines quadratischen Aufbaues von Schale Sch und Randkragen K läßt sich bei entsprechend exzentrischer Lage des Schlauchanschlußstutzens 10 eine noch weitergehende Variation erreichen.The elongated edge portion K ', which clearly projects beyond the underside U, can be integrally formed with the shell plus hose connection piece 10 of the roof covering plate. For accessibility or the optional assembly, however, the exemplary embodiment shown is implemented in such a way that the edge collar K is designed as the holder for the shell Sch designed as a separate component. For this purpose, a plug-in connection is selected such that the side wall 12 of the shell Sch lies in a form-fitting and thus sealing manner in an overlap with the edge collar K, more precisely with the edge collar section K '. An outside overlapping of the shell is provided. Side wall 12 and edge collar section K 'are connected to one another by means of intersecting screws 13. The relevant fastening zones are in the end areas of the corners. The through holes for possibly self-tapping screws 13 are at the same distance from these corner areas, so that the shell Sch can be assigned pivoted by 180 ° . With regard to the eccentric, ie eccentric arrangement of the hose connector 10 on the shell Sch, this has the advantage that a more ridge-side or a more eaves-side position is achieved for this connector. You can easily avoid slats or rafters in the way. In the case of a square structure of the shell Sch and the edge collar K, an even more extensive variation can be achieved if the hose connecting piece 10 is in a correspondingly eccentric position.

In jedem Fall sitzt der Schlauchanschlußstutzen 10 so am Boden 9 der Schale Sch, daß die Rohrwandung desselben die Mitte x des Bodens 9 tangiert (vergl. Fig. 6).In any case, the hose connection piece 10 sits on the bottom 9 of the shell Sch in such a way that the tube wall thereof touches the center x of the bottom 9 (cf. FIG. 6).

Der Boden 9 ist eingedellt. Er fällt zur genannten Mitte x hin allseitig geneigt ab, so daß eine Art Trichterform entsteht. Sich etwa ansammelndes Kondenswasser oder von Flugschnee herrührende Feuchtigkeit kann so gut ablaufen. Unter Berücksichtigung der Dachneigung liegt in solchen Fällen der Schlauchanschlußstutzen 10 zweckmäßig traufenseitig.The bottom 9 is dented. It falls inclined on all sides towards the center x, so that a kind of funnel shape is created. Accumulated condensation or moisture from flying snow can run off so well. In such cases, taking into account the roof pitch, the hose connector 10 is expediently on the eaves side.

Die Montage beschränkt sich bei lösbarer Schale Sch auf das Eindrehen der Schrauben 13.In the case of a detachable shell Sch, the assembly is limited to the screwing in of the screws 13.

Der Randkragen K ist, wie aus Fig. 5 hervorgeht, so gestaltet, daß seine Wandung die aus der Querwölbung im Mittelbereich M der Dacheindeckungsplatte resultierenden Innenkehlen 14 schließend kreuzt. Die Oberseite des Randkragens läuft in einer parallelen Ebene zur Grundebene der Dacheindeckungsplatte.The edge collar K, as can be seen from FIG. 5, is designed in such a way that its wall crosses the inner throats 14 resulting from the transverse curvature in the central region M of the roof covering plate. The top of the edge collar runs in a plane parallel to the base plane of the roofing slab.

Claims (2)

1. A roofing panel formed with a ventilation aperture (1) in the central area (M), such aperture being bouded by a peripheral edge collar (K) and having a cober (4) engaging after the style of a hood thereover and being associated with a funnel-shaped shell (Sch) directed towards the underside of roofing panel, said shell having a flexible tube connection (10), characterised in that the edge collar (K) which also projects over the underside of the roofing panel crossingly closes the inner fillet (14) of a transverse curvature of the roofing panel by its transverse portions and is the carrier of the shell (Sch) which is fitted overlappingly and which carries the fexible tube connection (10) in a position opposite an arcuate line of the inner surface (4') of the cover (4) in such manner that it is tangential to the center (x) of the base (9) of the shell (Sch), which has a rectangular or square cross-section.
2. A roofing panel according to claim 1, characterised in that the base (9) deepens funnel-fashion in a shallow pyramidal form towards the flexible tube connection.
