Description

Die Erfindung betrifft eine Anordnung zur Dachbedeckung mit einem mindestens eine Durchbrechung zur Dachentlüftung aufweisenden flächigen Dachelement gemäß dem Oberbegriff des unabhängigen Anspruches 1.The invention relates to an arrangement for roofing with a flat roof element having at least one opening for roof ventilation according to the preamble of independent claim 1.

Aus GB-A-2 199 860 und WO 85/01539 ist eine Lüfterdachplatte der gattungsbildenden Art bekannt. Über eine in der Dachplattenebene liegenden Durchbrechung befindet sich eine gaubenartig nach oben abstehende Abdeckung, die in Traufrichtung mit der Dachplattenebene eine offene Stufe als Luftaus-/-eintritt bildet. Unterhalb dieser Anordnung befindet sich ein Einsatz mit einem Auffangbereich und mit einer nach oben gegenüber der Durchbrechung versetzten Durchtrittsöffnung. Aufgrund der konstruktiven Ausgestaltung wird der Luftstrom mehrmals abgelenkt, wobei er im wesentlichen nach unten gerichtet ist.From GB-A-2 199 860 and WO 85/01539 a fan roof panel of the generic type is known. Above an opening in the roof plate level there is a dome-like upstanding cover, which forms an open step in the eaves direction with the roof plate level as an air outlet / inlet. Below this arrangement there is an insert with a collecting area and with a passage opening which is offset upwards relative to the opening. Due to the structural design, the air flow is deflected several times, essentially pointing downwards.

Ferner ist aus dem DE-GM 87 09 514 ein Dachentlüfterstein bekannt, welcher in einer gaubenartigen Ausführung mit etwa halbrundem Profil versehen ist, an dessen traufseitigen, offenen Ende ein Kunststoffteil angesetzt ist, welches in Verlängerung des Gaubenmantels ein Lüftungsgitter mit vertikalen Stegen und einer geschlossenen, konvex ausgebildeten und mit einem Abrißspoiler versehenen Frontfläche aufweist.Furthermore, from DE-GM 87 09 514 a roof vent block is known, which is provided in a dormer-like design with an approximately semicircular profile, on the eaves-side, open end a plastic part is attached, which is an extension of the dormer jacket a ventilation grille with vertical webs and a closed , convex and has a tear-off spoiler front surface.

Bei der Herstellung ist es also erforderlich, zwei unterschiedliche Materialien, nämlich Beton und Kunststoff, bündig, wasserdicht und dauerhaft miteinander zu verbinden, was die Herstellung relativ aufwendig macht. Außerdem ist eine in der Dachfläche sichtbare Kombination unterschiedlicher Materialien häufig unerwünscht. Ferner erzeugen gaubenartige Ausformungen in der Dachfläche optische Unterbrechungen, die manchmal im Hinblick auf den Gesamteindruck eines Daches als störend empfunden werden.During production, it is therefore necessary to connect two different materials, namely concrete and plastic, flush, watertight and permanently to one another, which makes production relatively complex. In addition, a combination of different materials visible in the roof surface is often undesirable. Furthermore, dormer-like shapes in the roof surface create optical interruptions that are sometimes perceived as disruptive with regard to the overall impression of a roof.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zur Dachbedeckung der gattungsgemäßen Art anzugeben, welche leicht montierbar ist und dennoch eine zuverlässige Abdichtung gewährleistet und welche sich darüber hinaus harmonisch in eine Dachlandschaft einpaßt.The invention has for its object to provide an arrangement for roofing of the generic type, which is easy to install and still ensures a reliable seal and which also fits harmoniously into a roof landscape.

Diese Aufgabe wird gemäß den kennzeichnenden Teilen des Ansprüches 1 gelöst. Durch eine derartige Ausbildung können Dachelemente, insbesondere Lüftungsziegel, mit einer größeren Durchbrechung verwendet werden, da diese nicht mehr nach oben hin gegen das Eindringen von Niederschlägen und Verunreinigungen abgedeckt werden müssen. Um ein volumen-bzw. flächenmäßig vorgegebenes Unterdach zu entlüften, sind daher weniger Lüftungsziegel als bisher erforderlich. Außerdem sind Lüftungsziegel innerhalb des Dachverbandes kaum mehr von den übrigen Ziegein zu unterscheiden, da sie im wesentlichen keine äußerlich erkennbaren Ausformungen aufweisen. Insbesondere wird hierbei eine nach außen sichtbare Materialvielfalt vermieden, weil lediglich das äußere Dachelement sichtbar ist und der Einsatz nach außen nicht in Erscheinung tritt.This object is achieved in accordance with the characterizing parts of claim 1. With such a design, roof elements, in particular ventilation tiles, with a larger opening can be used, since they no longer have to be covered at the top against the ingress of precipitation and contaminants. To a volume or To ventilate the sub-roof specified in terms of area, fewer ventilation tiles are required than previously. In addition, ventilation tiles within the umbrella organization can hardly be distinguished from the other goats, since they essentially have no externally recognizable shapes. In particular, an externally visible variety of materials is avoided because only the outer roof element is visible and the use does not appear to the outside.

Bei einer zur Unterdach- oder Dachraumentlüftung ausgebildeten Anordnung ist erfindungsgemäß auf dem Einsatz eine Querrippe angeordnet, welche am traufseitigen Rand der Durchbrechung des äußeren Dachelementes bis über die Durchbrechung hinausgeführt ist, und deren freies Ende als Abrißkante ausgebildet ist. Durch diese Kante wird ein Abriß einer über die Dachfläche streichenden Luftströmung bewirkt. Der dabei entstehende Unterdruck führt zu einem Absaugen von Luft aus dem Unterdach.In an arrangement designed for under-roof or roof space ventilation, a transverse rib is arranged on the insert according to the invention, which is led to the eaves-side edge of the opening in the outer roof element beyond the opening, and the free end of which is designed as a tear-off edge. This edge causes an air flow passing over the roof surface to be torn off. The resulting negative pressure causes air to be sucked out of the lower roof.

Es ist zweckmäßig, diese Querrippe mit Hilfe von in Abflußrichtung ausgerichteten Stützrippen in einem vorgegebenen Abstand vom Auffangbereich des Einsatzes anzuordnen, so daß zwischen dieser Rippe und dem Auffangbereich eine in Traufrichtung weisende Durchtrittsöffnung für die aufgefangenen Niederschläge vorhanden ist. Sind die Stützrippen an den Seiten der Durchbrechung angeordnet, so verhindern sie ebenso wie die Querrippe mit der Abrißkante einen Schrägeinfall von Niederschlägen in den Auffangbereich, wie er insbesondere bei starkem Wind auftreten könnte. Niederschläge werden somit definiert auf den Auffangbereich geleitet und ein unkontrolliertes Eindringen in den Dachraum wird verhindert.It is expedient to arrange this transverse rib with the aid of support ribs oriented in the outflow direction at a predetermined distance from the collecting area of the insert, so that there is a passage opening in the direction of the eaves for the collected precipitation between this rib and the collecting area. If the supporting ribs are arranged on the sides of the opening, they, like the transverse rib with the tear-off edge, prevent inclined precipitation in the catchment area, as it could occur especially in strong winds. Precipitation is thus directed to the collecting area and an uncontrolled penetration into the roof space is prevented.

Um die Stabilität und Biegesteifigkeit des Einsatzes weiter zu verbessern, sind Stützrippen über die gesamte Durchbrechung des äußeren Dachelements in vorgegebenen Abständen verteilt gitterartig angeordnet und bis in den Bereich der Durchbrechung geführt. Auf diese Weise wird auch ein Schutzgitter gegen das Eindringen von Blattwerk, Kleintieren oder ähnlichem gebildet. Durch den Eingriff der Stützrippen in die Durchbrechung des äußeren Dachelementes wird ferner der Einsatz in seiner Lage relativ zum Dachelement fixiert. Das hat den Vorteil, daß der Einsatz nicht gesondert auf den Dachlatten oder ähnlichem befestigt zu werden braucht, so daß die Anordnung während des Dachdeckens unproblematisch und ähnlich schnell wie eine normale Dachplatte aufgelegt werden kann.In order to further improve the stability and bending stiffness of the insert, support ribs are arranged in a grid-like manner at predetermined intervals over the entire opening of the outer roof element and are guided into the area of the opening. In this way, a protective grid against the penetration of foliage, small animals or the like is formed. The engagement of the support ribs in the opening in the outer roof element also fixes the insert in its position relative to the roof element. This has the advantage that the insert does not have to be fastened separately on the roof battens or the like, so that the arrangement can be placed on the roofing unproblematically and as quickly as a normal roof tile.

Eine besonders vorteilhafte Weiterbildung der Erfindung im Zusammenhang mit einer Unterdachentlüftung besteht darin, daß die Durchbrechung in Fließrichtung an der unteren Seite und im wesentlichen über die gesamte Breite des äußeren Dachelements angeordnet ist, daß die Durchtrittsöffnung des Einsatzes bezüglich der Durchbrechung nach oben versetzt angeordnet ist und daß der Querschnitt der Durchtrittsöffnung, der Durchbrechung sowie des Zwischenraums zwischen dem Dachelement und dem Einsatz im wesentlichen gleich ist. Durch diese Maßnahme kann ein maximaler Luftdurchtritt bei möglichst geringer Störung der Luftströmung erreicht werden. Um eine zuverlässige Wasserableitung zu gewährleisten, ist es zweckmäßig, den Einsatz entlang seiner beiden Seitenränder jeweils mit einem nach oben weisenden Kragen zu versehen. Der Kragen dient gleichermaßen zur Randversteifung des Einsatzes.A particularly advantageous development of the invention in connection with an under-roof ventilation is that the opening is arranged in the flow direction on the lower side and essentially over the entire width of the outer roof element, that the passage opening of the insert is arranged offset upwards with respect to the opening and that the cross section of the passage opening, the opening and the space between the roof element and the insert is substantially the same. This measure allows maximum air passage with the least possible disturbance of the air flow. To ensure reliable drainage of water, it is advisable to provide the insert along its two side edges with an upward-facing collar. The collar serves equally for stiffening the insert.

Es kann ferner auch zweckmäßig sein, daß der Einsatz oberhalb der Durchtrittsöffnung mit einer querverlaufenden Kröpfung versehen ist. Das hat den Vorteil, daß der Abstand und somit der Durchtrittsquerschnitt zwischen dem Einsatz und dem äußeren Dachelement vergrößert wird. Außerdem kann auf diese Weise der Auffangbereich wannenförmig ausgeformt und ausgesteift werden.It may also be appropriate that the insert is provided with a transverse offset above the passage opening. This has the advantage that the distance and thus the passage cross section between the insert and the outer roof element is increased. In addition, the collecting area can be shaped and braced in the manner of a trough.

Es ist auch vorteilhaft, das traufseitige Ende des Aufsatzes, welches innerhalb eines Dachverbandes auf dem nächstfolgenden Dachelement aufliegt, mit einer Tropfkante zu versehen. Außerdem kann es zweckmäßig sein, zumindest den unteren Rand, vorzugsweise jedoch auch die beiden anschließenden Seitenränder der Einsatz-Durchtrittsöffnung mit einem nach oben weisenden Kragen zu versehen. Auf diese Weise ist sichergestellt, daß beispielsweise bei geringer Dachneigung eventuell zurückstauende Niederschläge über die Durchtrittsöffnung in den Dachraum eindringen können.It is also advantageous to provide the end of the attachment on the eaves side, which rests on the next roof element within a roof structure, with a drip edge. In addition, it can be expedient to provide at least the lower edge, but preferably also the two adjoining side edges of the insert passage opening, with an upwardly facing collar. In this way it is ensured that, for example in the case of a low roof pitch, precipitation that may back up can penetrate into the roof space through the passage opening.

Es kann zur Lagefixierung des Dachelements auch vorteilhaft sein, daß es an seinem firstseitgen Ende unterseitig mit einem Steg zum Einhängen in eine Dachlatte versehen ist.To fix the position of the roof element, it may also be advantageous for it to be provided on the underside at its ridge-side end with a web for hanging in a roof batten.

Der Einsatz ist vorzugsweise aus Kunststoff oder Metall hergestellt.The insert is preferably made of plastic or metal.

Der Einsatz kann zur Verbesserung seiner Stabilität einen profilierten Querschnitt haben. Dies trägt vor allem zur Verbesserung der Steifigkeit bei. Eine höhere Steifigkeit ist auch durch das Vorsehen von Verstärkungsrippen auf dem Einsatz erzielbar. Die Verstärkungsrippen können hierbei parallel zur Fließrichtung verlaufen und gleichzeitig der Führung von abfließenden Niederschlägen dienen.The insert can have a profiled cross section to improve its stability. Above all, this helps to improve the rigidity. A higher rigidity can also be achieved by providing reinforcing ribs on the insert. The reinforcing ribs can run parallel to the flow direction and at the same time serve to guide runoff precipitation.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles weiter beschrieben:

The invention is further described below using an exemplary embodiment:
Fig. 1
shows a longitudinal section through an arrangement for venting a roof space; and
Fig. 2
shows a perspective view of the insert of the arrangement of FIG. 1st

Die in Fig. 1 veranschaulichte Anordnung, die auch als Flächenlüfter 9 bezeichnet werden kann, umfaßt ein als Lüfterziegel 10 ausgebildetes äußeres Dachelement für die Montage auf einem geneigten Dach. Der Lüfterziegel 10 hat an seinem unteren, traufseitigen Ende innerhalb der Ziegelfläche eine Durchbrechung 12, welche sich soweit wie möglich über die gesamte Breite des Lüfterziegels 10 senkrecht zur Zeichenebene erstreckt. Die Durchbrechung 12 weist einen rechteckigen Querschnitt auf. An seinem firstseitigen Ende ist der Lüfterziegel 10 mit einer Nase 14 an einer Dachlatte 16 in der Dachkonstruktion aufgehängt, während das traufseitige Ende 18 auf dem firstseitigen Ende des nächstfolgenden Dachziegels 20 aufliegt. Unter dem Lüfterziegel 10 ist ein Kunststoffeinsatz 8 angeordnet, der eine Schikane bildet, um einerseits durch die Durchbrechung 12 eindringende Niederschläge aufzufangen und abzuleiten und andererseits einen Luftstrom von innen nach außen zur Entlüftung des Unterdachs 7 sicherzustellen.The arrangement illustrated in FIG. 1, which can also be referred to as a surface fan 9, comprises an outer roof element designed as a fan tile 10 for mounting on an inclined roof. The fan brick 10 has at its lower, eaves-side end within the brick surface an opening 12 which extends as far as possible over the entire width of the fan brick 10 perpendicular to the plane of the drawing. The opening 12 has a rectangular cross section. At its ridge-side end, the fan tile 10 is suspended with a nose 14 on a roof batten 16 in the roof structure, while the eaves-side end 18 rests on the ridge-side end of the next roof tile 20. A plastic insert 8 is arranged under the fan tile 10, which forms a chicane, on the one hand to collect and discharge precipitation penetrating through the opening 12, and on the other hand to ensure an air flow from the inside to the outside for venting the lower roof 7.

Firstseitig liegt der Einsatz 8 auf der Dachlatte 16 auf, wobei er vom Gewicht des Lüfterziegels 10 von oben angedrückt wird. Sein traufseitiges Ende 25 liegt auf dem unten benachbarten Dachziegel 20 auf, wobei es mit einer stegartig nach unten ausgeformten Tropfkante 6 in eine Rinne am Dachziegel 20 eingreift.The insert 8 rests on the ridge side on the roof batten 16, being pressed from above by the weight of the fan tile 10. Its eaves-side end 25 lies on the roof tile 20 adjacent below, and it engages with a web-shaped, downwardly shaped drip edge 6 in a groove on the roof tile 20.

Der Einsatz 8 weist unterhalb der Durchbrechung 12 des Lüfterziegels 10 einen geschlossenen Auffangbereich 22 auf, welcher eindringende Niederschläge sammelt und nach unten auf den Dachziegel 20 ableitet. Im Auffangbereich 22 befinden sich in Fließrichtung ausgerichtete und vertikal abstehende Stützrippen 27, die bis in die Durchbrechung 12 reichen. Die Stützrippen 27 tragen an ihren traufseitigen Stirnflächen eine Querrippe 26, die bis über den Rand der Durchbrechung 12 hinausragt. Der über die Oberfläche des Lüfterziegels 10 überstehende Rand bildet eine scharfe Abrißkante 28. Eine über den Lüfterziegel 10 streichende Luftströmung reißt an der Kante 28 ab und erzeugt dadurch einen Unterdruck in der Durchbrechung 12. Die Querrippe 26 endet in einem vorgegebenen Abstand oberhalb des Auffangbereichs 22, so daß in Abflußrichtung ein genügender Auslauf 29 vorhanden ist. Die Querrippe 26 ist in dem wiedergegebenen Beispiel aus aerodynamischen Gründen mit einem abgerundeten Querschnitt versehen.
In Fließrichtung oberhalb des Auffangbereichs 22 ist der Einsatz 8 mit einer Durchtrittsöffnung 30 versehen, die eine Verbindung zum Unterdach 7 herstellt. Ein um den Rand der Durchtrittsöffnung 30 umlaufender Kragen 31 verhindert, daß durch die Durchbrechung 12 eintretender Niederschlag durch die Durchtrittsöffnung 30 in das Unterdach 7 gelangen kann, insbesondere im Falle einer niedrigen Dachneigung. Mit 5 ist eine aerodynamische Abrundung am Rand der Durchtrittsöffnung 30 bezeichnet.The insert 8 has a closed collecting area 22 below the opening 12 of the fan tile 10, which collects penetrating precipitation and leads it down onto the roof tile 20. In the catchment area 22 there are support ribs 27 which are oriented in the direction of flow and project vertically and extend into the opening 12. The support ribs 27 have a transverse rib on their eaves-side end faces 26, which extends beyond the edge of the opening 12. The edge projecting over the surface of the fan brick 10 forms a sharp tear-off edge 28. An air flow passing over the fan brick 10 breaks off at the edge 28 and thereby creates a negative pressure in the opening 12. The transverse rib 26 ends at a predetermined distance above the collecting area 22 , so that there is a sufficient outlet 29 in the drain direction. In the example shown, the transverse rib 26 is provided with a rounded cross section for aerodynamic reasons.
In the flow direction above the collecting area 22, the insert 8 is provided with a passage opening 30, which creates a connection to the lower roof 7. A collar 31 running around the edge of the passage opening 30 prevents precipitation entering through the opening 12 from reaching the sub-roof 7 through the passage opening 30, particularly in the case of a low roof pitch. 5 denotes an aerodynamic rounding at the edge of the passage opening 30.

Der Einsatz 8 erstreckt sich im wesentlichen in einer Ebene und parallel zur Deckfläche des Lüfterziegels 10 in einem vorgegebenen Abstand von dessen Unterseite. Über den Abstand wird ein Luftdurchtrittsquerschnitt 32 festgelegt, welcher der Querschnittsfläche sowohl der Durchtrittsöffnung 30 als auch der Durchbrechung 12 entspricht.The insert 8 extends essentially in one plane and parallel to the top surface of the fan brick 10 at a predetermined distance from its underside. An air passage cross-section 32 is determined via the distance, which corresponds to the cross-sectional area of both the passage opening 30 and the opening 12.

Wie die Fig. 2 weiter veranschaulicht, ist der Einsatz 8 entlang seiner beiden Längsseiten jeweils mit Aufkantungen 33 versehen, welche verhindern, daß eindringender Niederschlag über die Längsseiten hinaus im Stoßbereich der betreffenden Ziegel in das Unterdach gelangen kann. Die perspektivische Ansicht verdeutlicht ferner, daß die Stützrippen 27 ein Schutzgitter bilden, welches das Eindringen von Laubwerk oder ähnlichem in die Durchbrechung 22 verhindert. Außerdem fixiert es durch einen formschlüssigen Sitz in der Durchbrechung 12 den Einsatz 8 lagerichtig unterhalb des Lüfterziegels 10.As FIG. 2 further illustrates, the insert 8 is provided with upstands 33 along its two long sides, which prevent penetrating precipitation from reaching the lower roof beyond the long sides in the joint area of the tiles in question. The perspective view further clarifies that the support ribs 27 form a protective grid which prevents the penetration of leaves or the like into the opening 22. In addition, it fixes the insert 8 in the correct position below the fan brick 10 by means of a positive fit in the opening 12.
