Description

Die Erfindung betrifft Entlüfterdachziegel, insbes. Firstanschluß-Entlüfterziegel, die zur Entlüftung des Lüftungsquerschnittes unter der Dachhaut einsetzbar sind.The invention relates to vent roof tiles, in particular ridge connection vent tiles, which can be used for venting the ventilation cross section under the roof skin.

Nach der neuen DIN-Norm 4103 Teil 3 wird die Belüftung von geneigten, ausgebauten Dächern zwingend vorgeschrieben, um insbes. die Wärmedämmung vor einer Durchfeuchtung zu schützen. Vorschriften für die Entlüftung nicht ausgebauter Dächer sind ebenfalls zu erwarten, da eine fehlende oder unzureichende Unterlüftung in jedem Fall Nachteile hat. Hierbei sind insbes. folgende Gesichtspunkte zu betrachten :

  • 1. Es bildet sich ein Wärmestau und bei Wiederabkühlung Kondenswasser.
  • 2. Eindringende Feuchtigkeit, die nicht austrocknen kann, macht die Wärmedämmung unwirksam und gefährdet die Dachkonstruktion.
  • 3. Durch fehlende unterseitige Austrocknung der Dachziegel erhöht sich deren Wassersättigung soweit, daß sich die Zahl der Frosttauwechsel bei gleichzeitiger kritischer Sättigung nachweislich erhöht.
According to the new DIN standard 4103 part 3, the ventilation of pitched, removed roofs is mandatory, in particular to protect the thermal insulation from moisture. Regulations for the ventilation of undeveloped roofs are also to be expected, since a lack of ventilation or insufficient ventilation in each case has disadvantages. The following aspects should be considered in particular:
  • 1. A build-up of heat forms and condensate water when it cools down again.
  • 2. Penetrating moisture that cannot dry out makes the insulation ineffective and endangers the roof structure.
  • 3. Due to the lack of drying out of the roof tiles on the underside, their water saturation increases to such an extent that the number of frost thaw changes demonstrably increases with simultaneous critical saturation.

Nach der genannten DIN-Vorschrift muß der Entlüftungsquerschnitt am First mindestens 0,5 % der zugehörigen Dachfläche betragen, um die Dachkonstruktion durch eine ausreichende Entlüftung vor Feuchtigkeitsschäden zu bewahren.According to the aforementioned DIN regulation, the ventilation cross-section on the ridge must be at least 0.5% of the associated roof area in order to protect the roof structure from moisture damage by adequate ventilation.

Zur Dachentlüftung kennt man bereits sog. Lüfterfirste. Sie können bei Satteldächern und auch bei Walmdächern am Grat angebracht werden. Bei den hierzu bekannten Lüfterfirstziegeln erfolgt die Entlüftung durch Schlitze im Bereich ihrer gegenseitigen Längsüberdeckung. Aus diesen Öffnungen entweicht die Umluft. Der Nachteil solcher Lüfterfirstziegel besteht darin, daß durch die Öffnungen Flugschnee eindringen kann, so daß an der Dachfolie, der Verlattung usw. Feuchtigkeit entsteht.So-called fan ridges are already known for roof ventilation. They can be attached to the ridge on gable roofs and also on hipped roofs. In the case of the fan ridge tiles known for this purpose, ventilation takes place through slots in the area of their mutual longitudinal overlap. The circulating air escapes from these openings. The disadvantage of such fan ridge tiles is that flying snow can penetrate through the openings, so that moisture forms on the roof foil, the battens, etc.

Zur Entlüftung des Daches werden auch sog. Entlüfterziegel mit Entlüftungsgaupen verwendet. Sie werden aber aus architektonischen Gesichtspunkten nur ungern zur Dachentlüftung eingesetzt, da sie für das Aussehen der Dachfläche unvorteilhaft sind und das einheitliche Bild der Dachfläche stören. Außerdem haben derartige Ziegel den Nachteil, daß ihre Entlüftungsöffnungen direkt über der Dachfläche liegen. Im Falle einer über die Dachfläche hinwegstreichenden Luftströmung ist der Staudruck im Gaupenbereich am größten, so daß eine erhebliche Gefahr des Einwehens von Flugschnee oder des Eindringens von Schlagregen gegeben ist.So-called breather tiles with ventilation dormer are also used to vent the roof. From an architectural point of view, however, they are reluctant to use them for roof ventilation, since they are disadvantageous for the appearance of the roof area and disrupt the uniform appearance of the roof area. In addition, such tiles have the disadvantage that their ventilation openings are located directly above the roof surface. In the event of an air flow sweeping over the roof surface, the dynamic pressure is greatest in the dormer area, so that there is a considerable risk of blowing snow from flying in or driving rain entering.

In der Vergangenheit wurden auch Vorkehrungen getroffen, um die Entlüftung in die Firstanschlußziegel zu integrieren. Firstanschlußziegel besitzen zur besseren Auflage und zur Abdichtung gegen den Firstziegel ein anderes Kopffeld als normale Flächenziegel. Die sowieso benötigten Firstanschlußziegel für Entlüfterzwecke heranzuziehen hätte den Vorteil, daß keine weiteren Sonderziegel für die Entlüftung benötigt würden und somit Kosten eingespart werden könnten.In the past, precautions were also taken to integrate the ventilation in the ridge connection tiles. Ridge connection tiles have a different head field than normal flat tiles for better support and sealing against the ridge tile. The advantage of using the ridge connection tiles required for ventilation purposes would be that no further special tiles would be needed for ventilation and thus costs could be saved.

Die bekannten Firstanschluß-Entlüfterziegel weisen im Kopffeld zwei Randauflageflächen für die Firstziegel auf. Zwischen der Unterkante des quer auf dem Firstanschluß-Entlüfterziegel aufliegenden Firstziegels und der Oberfläche des Firstanschluß-Entlüfterziegels verbleibt ein Querspalt, durch den die durch den Firstziegel zugeführte Umluft austritt.The well-known ridge connection vent tiles have two edge contact surfaces for the ridge tiles in the header. Between the lower edge of the ridge tile resting transversely on the ridge connection ventilation tile and the surface of the ridge connection ventilation tile, there remains a transverse gap through which the circulating air supplied through the ridge tile exits.

Es hat sich jedoch gezeigt, daß durch den Querspalt Feuchtigkeit, Schlagregen und Flugschnee eindringen können und sich, wie vorstehend im Zusammenhang mit den bekannten Entlüftergaupen beschrieben wurde, auf der Dachfolie, der Verlattung usw. niederschlagen.However, it has been shown that moisture, driving rain and flying snow can penetrate through the transverse gap and, as described above in connection with the known ventilating dormers, are deposited on the roof film, the battens, etc.

Auch der im Zusammenhang mit Entlüftergaupen bereits erwähnte Staudruck, hervorgerufen durch den über die Dachfläche hinwegstömenden Luftstrom, verhindert den Austritt des mit geringerem Druck austretenden Umluftstromes.The back pressure already mentioned in connection with ventilating dormers, caused by the air flow flowing over the roof surface, also prevents the outflow of the circulating air flow emerging at a lower pressure.

Ein Entlüfterdachziegel gemäß den Oberbegriff des Anspruchs 1 ist aus der DE-C-466 548 bekannt.A vent roof tile according to the preamble of claim 1 is known from DE-C-466 548.

Der Erfindung liegt daher die Aufgabe zugrunde, die bekanten Firstanschluß-Entlüfterziegel dahingehend zu verbessern, daß sie die vorstehend genannten Nachteile der bekannten Firstanschluß-Entlüfterziegel nicht mehr aufweisen, eine sichere Entlüftung der Dachfläche gewährleisten und gleichzeitig einen größtmöglichen Schutz gegen das Eindringen von Wasser und Schnee liefern. Des weiteren ist Aufgabe der Erfindung, Entlüfterziegel mit Entlüftungsgaupen sowie Lüfterfirstziegel in der Weise weiterzuentwickeln, daß die Dachfläche einwandfrei und sicher entlüftet und das Eindringen von Wasser, insbes. durch Schlagregen und Schnee, insbes. Flugschnee, verhindert wird.The invention is therefore based on the object to improve the known ridge connection breather tiles to the effect that they no longer have the disadvantages of the known ridge connection breather tiles mentioned above, ensure reliable ventilation of the roof surface and at the same time provide the greatest possible protection against the ingress of water and snow deliver. Furthermore, it is an object of the invention to further develop ventilation bricks with ventilation dormer and fan ridge bricks in such a way that the roof surface is vented properly and safely and the ingress of water, in particular by driving rain and snow, in particular flying snow, is prevented.

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.According to the invention, this is achieved by the characterizing features of claim 1.

Die Kanäle dienen als Entlüftungsöffnungen für die Ableitung der durch die Firstziegel ausströmenden Umluft, die Nocken und/oder Stege gleichzeitig als Schutz gegen eindringende Feuchtigkeit. Dieser Schutz wird insbes. dann erreicht, wenn nach einer vorzugsweisen Ausbildung der Erfindung die einzelnen Stege aus zueinander abgewinkelten, miteinander verbundenen Stegabschnitten gebildet sind. Durch den hierdurch erzielten labyrinthartigen Verlauf der Kanäle wird der Luftstrom zwar umgelenkt, aber nicht am Austritt gehindert, während ein Schutz insbes. gegen das Eindringen von Flugschnee und dergl. geschaffen wird. Weitere vorteilhafte Nocken- oder Stegausbildungen ergeben sich aus den Unteransprüchen und der Zeichnung.The channels serve as ventilation openings for the discharge of the circulating air flowing out through the ridge tiles, the cams and / or webs at the same time as protection against the ingress of moisture. This protection is achieved in particular if, according to a preferred embodiment of the invention, the individual webs are formed from web sections that are angled to one another and connected to one another. The resulting labyrinthine course of the channels deflects the air flow, but does not prevent it from escaping, while providing protection, in particular, against the penetration of flying snow and the like. Further advantageous cam or web designs result from the subclaims and the drawing.

Um aber gleichzeitig die Entlüftungseigenschaften des Ziegels zu verbessern, ist das Kopffeld des Ziegels mit einer durch einen Querkanal von den Stegen getrennten, quer über die Ziegeloberfläche verlaufenden Stauleiste abgeschirmt. Hierdurch werden die Entlüftungskanäle von dem am Fuß eines Firstes besonders hohen Staudruck der über die Dachfläche hinwegstreichenden Luftströmung abgeschirmt. Durch entsprechende Formgebung des Profiles der Stauleiste kann erreicht werden, daß sich im Bereich des Kopffeldes des Ziegels, insbes. im Bereich der Kanäle hinter der Stauleiste, ein Unterdruck aufbaut, der die Entlüftungsvorgänge unterstützt. Ein solcher auf die Umluft wirkender Sog ist vor allem dann von Bedeutung, wenn sich ein Teil der Kanäle durch Flugschnee verstopft haben sollte.However, in order to improve the ventilation properties of the brick at the same time, the head area of the brick is shielded by a damming bar which is separated from the webs by a transverse channel and runs across the brick surface. As a result, the ventilation ducts are shielded from the particularly high dynamic pressure at the base of a ridge of the air flow passing over the roof surface. By appropriate shaping of the profile of the baffle bar, it can be achieved that a vacuum builds up in the area of the head area of the brick, in particular in the area of the channels behind the baffle bar, which supports the ventilation processes. Such a suction effect on the circulating air is particularly important if part of the channels should be blocked by flying snow.

Die erfindungsgemäße Ausbildung des Kopffeldes der Firstanschluß-Entlüfterziegel kann ihre Wirkung nur dann voll entfalten, wenn beim Einbau der Firstanschluß-Entlüfterziegel der Entlüftungsquerschnitt in ausreichendem Maße frei zugänglich bleibt, also nicht zu weit von den aufgesetzten Firstziegeln eingeengt wird. Um dies zu gewährleisten, sind vorzugsweise aus Sicherheitsgründen im Kopffeld des Firstanschluß-Entlüfterziegels Begrenzungsnocken vorgesehen, die Anschläge für die Lage der Firstziegel auf den Firstanschluß-Entlüfterziegeln bilden.The inventive design of the head field of the ridge connection vent brick can only fully develop its effect if, when installing the ridge connection vent brick, the ventilation cross section remains freely accessible to a sufficient extent, that is, it is not constricted too far from the ridge tiles placed on it. To ensure this, limiting cams are preferably provided in the header of the ridge connection vent tile for safety reasons, which form stops for the position of the ridge tiles on the ridge connection vent tile.

Die Ausgestaltung der Entlüfterziegel mit Entlüftungsgaupen nach der Erfindung erfolgt in der Weise, daß der stirnseitigen Öffnung der Entlüftungsgaupe eine Stauleiste gegenübergestellt wird, die in ihrer Höhe und Formgebung z. B. der Entlüftungsgaupe entspricht, die aber wahlweise auch mit größerer Höhe ausgebildet sein kann. Dabei stehen sich die Stirnflächen von Entlüftungsgaupe und Stauleiste in geringem Abstand gegenüber, während die Außenflächen von Entlüftungsgaupe und Stauleiste in ihrer gemeinsamen Formgebung sich z. B. zu einer strömungstechnisch günstigen Form (Stromlinienform) ergänzen. Durch die Anordnung der Stauleiste wird an der Entlüftungsgaupe anstehender Wind daran gehindert, einen Staudruck zu erzeugen. Aufgrund, der stromlinienförmigen Formgebung der Kombination aus Entlüftungsgaupe und Stauleiste, aber auch, wenn die Stauleiste die Höhe der Entlüftungsgaupe wesentlich übersteigt, entsteht beim Hinwegstreichen von Luft über das Dach ein Sog an der Trennstelle zwischen Entlüftungsgaupe und Stauleiste, der jedes Eindringen von Wasser oder Schnee in die Öffnung verhindert und gleichzeitig die Entlüftung unterstützt.The design of the vent brick with ventilation dormer according to the invention is carried out in such a way that the front opening of the ventilation dome is juxtaposed with a baffle bar, the height and shape of which, for. B. corresponds to the ventilation gap, but can optionally also be designed with a greater height. The end faces of the venting bead and the baffle bar face each other at a short distance, while the outer surfaces of the breather bead and the baffle bar are in their common shape, for. B. to a fluidically favorable form (streamlined form). The arrangement of the baffle bar prevents the wind that is present at the ventilation gap from generating a dynamic pressure. Due to the streamlined shape of the combination of ventilation bead and baffle bar, but also if the baffle bar significantly exceeds the height of the breather bead, there is suction at the separation point between breather bead and baffle bar when air is swept away over the roof, preventing any ingress of water or snow prevented in the opening and at the same time supports the ventilation.

In der Anwendung der Erfindung auf Lüfterfirstziegel wird letzterer ebenfalls mit einer Stauleiste am einen Ende oder an beiden Enden versehen, die die Aufgabe hat, die vorbeistreichende Luft zu führen und am Entlüftungsspalt zwischen zwei aneinander anschließenden Ziegeln einen Sog zu erzeugen, der das Eindringen von Regen oder Schnee wirksam verhindert.In the application of the invention to fan ridge tiles, the latter is also provided with a damming bar at one end or at both ends, which has the task of guiding the air flowing past and creating a suction at the ventilation gap between two adjacent tiles, which prevents the ingress of rain or snow effectively prevented.

Die Stauleiste 9 begrenzt auch das kopfseitige Ende de Wulst 3.The so-called head field 7 of the brick 1 is delimited by a head edge strip 8, which is drawn up along the head-side outer edge of the brick 1 and by a storage ledge 9 running parallel to the head edge strip 8 at a distance from the latter across the brick surface 2. The stowage bar 9 also delimits the head-side end of the bead 3.

Im Kopffeld 7, und zwar im Bereich zwischen der Kopfrandleiste 8 und der Stauleiste 9, ist ein Steglabyrinth 10 (siehe Fig. 4a) vorgesehen. Dieses Labyrinth 10 ist aus einer Vielzahl von Stegen 11 gebildet, die zueinander benachbart verlaufen und Entlüftungskanäle 12 für die Ableitung der von dem hier nicht dargestellten, auf dem Firstanschluß-Entlüfterziegel 1 quer aufliegenden Firstziegel zugeführten, aus dem Dachinneren aufsteigenden und durch die Öffnungen der Firstziegel ausströmenden Umluft begrenzen.A web labyrinth 10 (see FIG. 4a) is provided in the head field 7, specifically in the area between the head edge strip 8 and the storage rail 9. This labyrinth 10 is formed from a multiplicity of webs 11 which run adjacent to one another and ventilation channels 12 for the discharge of the ridge tile from the roof ridge vent tile 1, not shown here, which is fed transversely, ascending from the roof interior and through the openings of the ridge tile limit escaping circulating air.

In Fig. 1 sind die Stege 11 entsprechend der schematischen Darstellung in Fig. 4a aus zueinander abgewinkelten, miteinander verbundenen Stegabschnitten 11 a, 11 b gebildet. Eine solche Konfiguration hat den Vorteil, daß die Umluft aus den Entlüftungskanälen 12 austreten, Flugschnee oder Schlagwasser aber nicht durch den Firstziegel vordringen und unter die Dachhaut gelangen kann. Die hier gewählte Anordnung der Stege hat den besonderen Vorteil, daß sie trotz der erzielten Abschirmung den nutzbaren Entlüfterquerschnitt nicht unnötig verringert.In Fig. 1, the webs 11 are formed according to the schematic representation in Fig. 4a from mutually angled, interconnected web sections 11 a, 11 b. Such a configuration has the advantage that the circulating air can escape from the ventilation ducts 12, but flying snow or blow water cannot penetrate through the ridge tile and get under the roof skin. The arrangement of the webs chosen here has the particular advantage that, despite the shielding achieved, it does not unnecessarily reduce the usable vent cross section.

Die Sperrwirkung der in Fig. 4a gezeigten Steganordnung wird besonders deutlich aus der in Fig. 3 in perspektivischer Darstellung gezeigten Anordnung der Stege 11, deren Querschnittsprofil die Form eines Trapezes aufweist. Die Stege 11 sind so nebeneinander angeordnet, daß sich ihre Scheitel 11c etwa auf der Höhe der Schenkelenden des jeweils benachbarten Steges 11 befinden. Hierdurch wird die gewünschte Umlenkung der Luft erreicht und gleichzeitig das Eindringen von Feuchtigkeit erschwert. Eine ähnliche Wirkung kann auch durch Steg- bzw. Nockenanordnungen erzielt werden, wie sie in den Figuren 4b, c und d schematisch angedeutet sind. In Fig. 4b handelt es sich um Stege 20 mit ebenfalls winkelartiger Verbindung in Form eines « S •, bei Fig. 4c um ein mäanderartige Konfiguration 21.The blocking effect of the web arrangement shown in FIG. 4a becomes particularly clear from the arrangement of the webs 11 shown in perspective view in FIG. 3, the cross-sectional profile of which has the shape of a trapezoid. The webs 11 are arranged side by side so that their apices 11c are approximately at the level of the leg ends of the adjacent web 11. This achieves the desired redirection of the air and at the same time impedes the penetration of moisture. A similar effect can also be achieved by web or cam arrangements, as are indicated schematically in FIGS. 4b, c and d. 4b it is webs 20 with also an angular connection in the form of an “S •, in FIG. 4c a meandering configuration 21.

Die in Fig. 4d gezeigte Nockenanordnung ist aus in Abständen zueinander verlaufenden, parallelen Nockenreihen 22, 23, 24 gebildet. Innerhalb einer Nockenreihe sind die Nocken in Abständen voneinander angeordnet. Die Nocken einander benachbarter Reihen 22, 23, 24 sitzen jeweils auf Lücke. Eine solche Nockenanordnung bietet einen besonders guten Schutz gegen das Eindringen von Wasser oder Schnee. Es muß aber in Kauf genommen werden, daß der für die Umluft zur Verfügung stehende Entlüftungsquerschnitt gegenüber der in Fig. 4a gezeigten Steganordnung erheblich verringert ist.The cam arrangement shown in FIG. 4d is formed from parallel, parallel rows of cams 22, 23, 24. The cams are arranged at a distance from one another within a row of cams. The cams of adjacent rows 22, 23, 24 each sit on a gap. Such a cam arrangement offers particularly good protection against the ingress of water or snow. However, it must be accepted that the ventilation cross section available for the circulating air is considerably reduced compared to the web arrangement shown in FIG. 4a.

Um den hohen Staudruck der das Dach überstreichenden Luftströmung am Fuß des Firstes aus dem Entlüftungsbereich zu entfernen, ist die Stauleiste 9 in einem Abstand vom Fußpunkt der Stege 11 angeordnet. Ihr Querschnittsprofil, aus der Fig. 2 erkennbar, ist so gewählt, daß es für die über das Dach zum First hin strömende Luft einen durch die Strömungslinien in Fig. 2 angedeuteten Strömungsverlauf verursacht. An den Stellen hoher Stromliniendichte bildet sich ein Unterdruck aus, der auf die durch den Kanal 13 strömende Umluft einen Sog in Richtung des Pfeiles P ausübt und damit die Ableitung der Umluft begünstigt. Das Profil der der Ziegelfläche 2 zugewandten Seite der Stauleiste 9 hat z. B. eine etwa hyperbelförmige Gestalt, wobei sich die Hyperbel asymptotisch der Ziegeloberfläche 2 bzw. der Staufläche 9 nähert. Dabei ist die Höhe der Stauleiste 9 größer als die der Kopfrandleiste 8.In order to remove the high dynamic pressure of the air flow sweeping over the roof at the foot of the ridge from the ventilation area, the baffle bar 9 is arranged at a distance from the base point of the webs 11. Its cross-sectional profile, which can be seen in FIG. 2, is selected such that it causes a flow profile indicated by the flow lines in FIG. 2 for the air flowing over the roof towards the ridge. At the points of high streamline density, a negative pressure forms which exerts a suction on the circulating air flowing through the channel 13 in the direction of the arrow P and thus favors the discharge of the circulating air. The profile of the brick surface 2 facing side of the storage rail 9 has z. B. an approximately hyperbolic shape, the hyperbola approaching the brick surface 2 or the storage surface 9 asymptotically. The height of the storage bar 9 is greater than that of the top edge bar 8.

Eine weitere Funktion der hochgezogenen Stauleiste 9 besteht darin, das Eindringen von Feuchtigkeit in die mit dem Firstziegel in Verbindung stehenen Kanäle 12 zu verhindern. Dieser Feuchtigkeitsschutz wird, wie bereits erläutert, durch die Formgebung der Stege 11 verstärkt, die labyrinthartig den Zugang zu den Entlüftungsschlitzen der Firstziegel versperren und damit das Eindringen von Flugschnee und Feuchtigkeit nahezu unmöglich machen.Another function of the raised baffle bar 9 is to prevent the ingress of moisture into the channels 12 connected to the ridge tile. This moisture protection is, as already explained, reinforced by the shape of the webs 11, which block access to the ventilation slots of the ridge tiles in a labyrinth-like manner and thus make the penetration of flying snow and moisture almost impossible.

Um einerseits sicherzustellen, daß die Firstziegel ordnungsgemäß auf die Firstanschluß-Entlüfterziegel aufgesetzt, d. h. so befestigt werden, daß die durch die Schlitze der Firstziegel zugeführte Umluft in die Kanäle 12 zwischen den Stegen 11 eingeleitet wird und dann ungehindert aus dem Kanal 13 in die Umgebung austreten kann, und andererseits die Verlegearbeiten nicht unnötig zu erschweren, sind an der Stauleiste 9 und an der Kopfrandleiste 8 Begrenzungsnocken 14 bzw. 15 vorgesehen. Der Begrenzungsnocken 14 ist im Bereich einer regelmäßig seitlich am Ziegel 1 vorgesehenen Randauflageleiste 16 angeordnet und erstreckt sich quer zur Stauleiste 9 in Richtung zur Kopfleiste 8. Der Begrenzungsnocken 15 sitzt in Form eines Höckers 15 ebenfalls im Bereich der Randauflageleiste 16 auf der Kopfrandleiste 8.On the one hand, to ensure that the ridge tile is properly placed on the ridge connection vent tile, i. H. are attached in such a way that the circulating air supplied through the slots of the ridge tile is introduced into the channels 12 between the webs 11 and can then emerge unhindered from the channel 13 into the environment, and on the other hand the laying work is not made unnecessarily difficult, are on the ram bar 9 and 8 limiting cams 14 and 15 are provided on the top edge strip. The limiting cam 14 is arranged in the area of an edge support bar 16 provided laterally on the brick 1 and extends transversely to the storage bar 9 in the direction of the head bar 8. The limiting cam 15 is also in the form of a hump 15 in the area of the edge support bar 16 on the top edge bar 8.

Es ist aber auch möglich, gemäß Fig. 5 einen Begrenzungsnocken 17 an der Kopfrandleiste 8 gegenüber einem Nocken 18 anzuordnen, der ebenfalls in das Kopffeld hineinragt und zur Stauleiste 9 hin gerichtet ist.However, it is also possible, according to FIG. 5, to arrange a limiting cam 17 on the top edge strip 8 opposite a cam 18, which likewise protrudes into the head field and is directed towards the storage bar 9.

Ein Entlüfterziegel 25 mit Entlüftungsgaupe 26 nach Fig. 6, 7 ist auf der Stirnseite 27 geöffnet und weist eine Stauleiste 28 auf, deren Stirnseite 29 der Stirnseite 27 gegenübersteht. Der Abstand der beiden Stirnflächen 27 und 29 beträgt beispielsweise 20 mm und kann zwischen ca 10 und ca 50 mm betragen. Die Stauleiste 28 ist auf der von der Stirnseite 29 abgewandten Seite 30 gekrümmt, z. B. im Querschnitt teilkreisförmig ausgebildet, derart, daß die Außenfläche 30 der Stauleiste 28 und die Außenfläche der Entlüftungsgaupe 26 sich zu einer Stromlinienform ergänzen. Die Stauleiste 28 kann jedoch die Entlüftungsgaupe 26 auch wesentlich überragen.6, 7 is open on the end face 27 and has a storage bar 28, the end face 29 of which faces the end face 27. The distance between the two end faces 27 and 29 is, for example, 20 mm and can be between approximately 10 and approximately 50 mm. The storage rail 28 is curved on the side facing away from the end face 29, z. B. formed in cross-section part-circular, such that the outer surface 30 of the baffle 28 and the outer surface of the ventilation bead 26 complement each other to form a streamlined shape. However, the baffle bar 28 can also project significantly beyond the ventilation bead 26.

Bei der in Fig. 8, 9 dargestellten Ausführungsform eines Lüfterfirstziegels 31 ist entweder an dem überlappten Ende des Firstziegels eine Stauleiste 32 vorgesehen, oder aber es sind an beiden Enden des Firstziegels Stauleisten 32, 33 vorgesehen, wobei jeweils die einander gegenüberstehenden Stauleisten 32, 33' zweier aneinander anschließender Firstziegel sich z. B. so ergänzen, daß ein stromlinienförmiger Übergang an den beiden einander zugewandten Stauleisten erzielt wird, der einen Sog im Luftführungskanal 34 bewirkt. Auch bei dieser Ausführungsform der Erfindung kann die eine Stauleiste im Vergleich zur anderen wesentlich höher ausgebildet sein. Des weiteren kann generell bei den vorbeschriebenen Ausführungsformen die gekrümmte Oberfläche der Stauleiste(n) konkav oder konvex ausgebildet sein.In the embodiment of a fan ridge tile 31 shown in FIGS. 8, 9, a baffle bar 32 is either provided at the overlapped end of the ridge tile, or baffle bars 32, 33 are provided at both ends of the ridge tile, the opposing baffle bars 32, 33 in each case 'two adjacent ridge tiles z. B. add so that a streamlined transition is achieved on the two facing ram ledges, which causes suction in the air duct 34. In this embodiment of the invention, too, one baffle bar can be made significantly higher than the other. Furthermore, in the above-described embodiments, the curved surface of the baffle strip (s) can generally be concave or convex.
