Definitions

  • the invention relates to a ridge ventilation on roofs with rows arranged one behind the other in the roof longitudinal direction underneath the ridge cover caps, with their front-side mouth openings open to the opposite roof slopes, individual channels crossing the cavity below the cover caps, which are open to flow zones of the air that open from the distance spaces are formed in the area between the individual channels.
  • Such a ridge ventilation is known from DE-A-2451 058.
  • the known roving ventilation requires the use of a special ridge beam, which is provided on its underside with cutouts into which individual insert pieces with a U-shaped cross-section are inserted, which form the channels. These inserts are provided with cover walls that leave openings that connect to the air-access zones. Profiled strips are attached to the ends of the channels, which create the gaps between the channels and the roofing panels on the adjacent sloping ceilings. It can be seen that such a ridge ventilation is made up of a large number of relatively complicated individual parts, which must also be laid with great care. As a result, such ridge ventilation is relatively expensive, which, despite its good effect, prevents widespread use.
  • the invention is therefore based on the object to develop such a ridge ventilation such that it consists of a smaller number of easily manufactured parts and can also be retrofitted to existing roofs with ease.
  • the invention accordingly makes use of a ridge cover with sealing strips, as is known, for example, from DE-C-2701 196.
  • the sealing strips bring about an essentially tight seal of the roof space
  • the ridge ventilation can be produced by the design of these sealing strips according to the invention, which has individual channels crossing the cavity under the cover caps, which are open to air rise zones. It is therefore only necessary to replace the known sealing strips with the sealing strips designed according to the invention in order to achieve a very effective ridge ventilation.
  • the sealing strips designed according to the invention can be produced in a simple manner and are just as easy to attach to the roof screed as the conventional sealing strips. Therefore, the ridge ventilation according to the invention can be produced at very low cost and can also be easily retrofitted to existing roofs.
  • the features extend to the underside of the ridge cap, and the openings are made in the mutually opposite side walls of the features.
  • the top of the embossments can rise at least in the region of the openings from the longitudinal center plane parallel to the individual channels to the side walls. In this way, well separated individual channels are created, which leads to maximum effectiveness of the roof ventilation, and it has the profiling of the top of the forms a beneficial effect both in terms of mechanical stability and the deflection of the rising air in the direction of those in the side walls arranged openings.
  • the features end in a tip in the direction of the outer edge of the sealing strips.
  • the air flowing in at the sloping roof is distributed to the individual ducts largely without vortexes.
  • a nozzle-like narrowing occurs at the inlet of the individual channels, which results in a reduction in pressure in the region of the openings and thus an improvement in the ventilation.
  • a particularly favorable and stable design is obtained if a section of the formations which has the openings and which has side walls which are essentially perpendicular to one another and parallel to the surface of the sealing strip, is followed by a section which is triangular both in plan and in cross section and decreases in height to the outside .
  • the sealing strips can be angled downward in the region of the transition from the section having the openings to the triangular section. This also results in an optimal adaptation of the sealing strip to the shape of the ridge cover caps.
  • the characteristics can in principle extend to the inner edge of the sealing strips if the sealing strips are attached to the ridge screed with abutting edges, as is known from DE-C-2 701 196. In a preferred embodiment of the invention, however, the characteristics extend towards the inner edge of the Sealing strips only up to an angled edge strip, which is attached to the top of the ridge batten. This measure makes it easier to attach the weather strip to the ridge batten.
  • the distance that arises between the features lying one behind the other in the longitudinal direction of the channels is not disruptive because, in the case of the air flow forced through the individual channels, a transverse flow through these spaces in the longitudinal direction of the ridge can practically not occur. In principle, however, there would also be the possibility of forming the sealing strips in one piece in such a way that they extend from one to the opposite other sloping roof and are fastened to the ridge screed in the region of their center.
  • the sealing strips are usually provided on their outer edges lying on the roofing panels with cutouts which are adapted to the profile of the roofing panels, so that the roofing panels engage with these beads in their cutouts.
  • This design of the sealing strips requires the provision of different embodiments for the different, commercially available roofing sheets.
  • the position of the sealing strips is determined by the arrangement of the roofing panels. Therefore, the roof covering plates arranged on the two roof slopes adjacent to the ridge screed must be aligned with each other in such a way that, given the position of the sealing strips lying on a common section of the ridge screed, the characteristics and, accordingly, the individual channels delimited therefrom are aligned, as is the case for one optimal ventilation is required.

  • elongated sealing bodies made of a highly elastic material are arranged between the outer edges of the sealing strips and the roof covering plates, which seal the gap between the edges of the sealing strips and the roof covering plates .
  • the sealing bodies can advantageously consist of a foamed plastic, in particular a foamed polyurethane, and can be attached, in particular glued, to the edges of the sealing strips.
  • the sealing bodies have an essentially rectangular cross section, the height of which is measured perpendicular to the underside of the sealing strips and is approximately twice as large as its width.
  • the height of the sealing strip is approximately 50 mm. This height is sufficient to ensure that it fits snugly against a wide variety of profiles of roofing panels, while on the other hand the width ensures that the sealing body fits snugly against the roofing panels. It can be particularly advantageous if the sealing body is not exactly rectangular, but rather has the cross section of a parallelogram, the acute angles of which lie at the upper, inner and lower, outer corners.
  • the sealing bodies are then slightly outwards and have a tip pointing slightly downwards and outwards, which also ensures that they fit snugly against the fine profiles of the roof covering panels.

  • the edges 4 and 5 formed by angling the edge strips 2 and 3 run in the longitudinal direction of the sealing strip 1.
  • the one edge strip 2 has a width B which is slightly less than half Wide ridge planks.
  • In this edge strip there is a number of nail holes 6, which make it easier to nail this edge strip onto a ridge plank.
  • the other edge strip 3 is adapted to the profile of such roofing panels by cutouts 7, the spacing of which is equal to the spacing of the longitudinal beads of roofing panels with which the sealing strip 1 is intended to cooperate. As can be seen, the cutouts 7 are arranged symmetrically to the center of the sealing strip 1.
  • the sealing strip has upward-directed features 8 which extend over the entire width of the central section and are arranged parallel to one another at a distance.
  • These features 8 have a first section 9, the side walls 10 of which extend essentially perpendicular to the surface of the sealing strip 1 and are provided with openings 11.
  • This first section is adjoined by a second section 12 which extends in the direction of the outer edge strip 3 and which has a triangular shape both in plan and in cross section.
  • the central section of the edge strip is angled again in the area of the transition from the first section 9 of the features 8 to its second section 12 in the same sense as the edge strips 2 and 3.

  • the features 8 ideally extend to the inside of the caps 29, so that the gaps between the expressions 8 not only downwards and to the side, but also at the top are closed and form transverse channels to the ridge 13, which are open with their front openings to the opposite roof slopes.
  • These individual channels are connected via the openings 11, which are located in the side walls 10 of the forms, with air rise zones which are formed by the interior spaces of the forms 8, which in turn are connected to the roof space located below the sealing strips.
  • These interiors of the forms 8 are at the same time spaces between the individual channels 13.
  • this roving ventilation is based on the fact that practically in every wind direction the individual channels are flowed through by an air stream which entrains air from the openings 11 in the walls 10 of the forms, which air is drawn off from the roof interior to be vented.
  • This venting is only slightly dependent on the wind speed and wind direction.
  • the air guiding webs 15, which are arranged at the ends of the individual channels 13 parallel to the forms 8, also contribute to this independence. It is particularly important that no back pressure can occur that prevents the roof from being vented. When there is no wind, the ventilation based on natural convection is not prevented.
  • the triangular outer sections 12 of the forms cause a constant inflow of air at the ends of the channels, so that on the one hand a vortex formation is prevented and on the other hand a nozzle effect promoting ventilation occurs.

Description

Die Erfindung betrifft eine Firstentlüftung an Dächern mit unterhalb der First-Abdeckkappen in Dachlängsrichtung reihenförmig hintereinander angeordneten, mit ihren stirnseitigen Mündungsöffnungen zu den gegenüberliegenden Dachschrägen hin offenen, den Hohlraum unterhalb der Abdeckkappen kreuzenden Einzelkanälen, die zu Strömungszonen der Luft hin offen sind, die von den sich im Bereich zwischen den Einzelkanälen befindenden Abstandsräumen gebildet werden.The invention relates to a ridge ventilation on roofs with rows arranged one behind the other in the roof longitudinal direction underneath the ridge cover caps, with their front-side mouth openings open to the opposite roof slopes, individual channels crossing the cavity below the cover caps, which are open to flow zones of the air that open from the distance spaces are formed in the area between the individual channels.

Eine solche Firstentlüftung ist aus der DE-A-2451 058 bekannt. Die bekannte Firstenentlüftung erfordert die Anwendung eines besonderen Firstbalkens, der an seiner Unterseite mit Ausschnitten versehen ist, in die einzelne, im Querschnitt U-förmige Einsatzstücke eingesetzt sind, welche die Kanäle bilden. Diese Einsatzstücke sind mit Deckwänden versehen, die Öffnungen freilassen, welche die Verbindung zu den Luftaufstiegszonen herstellen. An den Enden der Kanäle sind Profilleisten angebracht, welche die Spalte zwischen den Kanälen und den Dacheindeckungsplatten auf den angrenzenden Dachschrägen herstellen. Es ist ersichtlich, daß eine solche Firstentlüftung aus einer Vielzahl relativ komplizierter Einzelteile aufgebaut ist, die außerdem mit großer Sorgfalt verlegt werden müssen. Infolgedessen ist eine solche Firstentlüftung relativ kostspielig, was trotz ihrer guten Wirkung einer verbreiteten Anwendung entgegensteht.Such a ridge ventilation is known from DE-A-2451 058. The known roving ventilation requires the use of a special ridge beam, which is provided on its underside with cutouts into which individual insert pieces with a U-shaped cross-section are inserted, which form the channels. These inserts are provided with cover walls that leave openings that connect to the air-access zones. Profiled strips are attached to the ends of the channels, which create the gaps between the channels and the roofing panels on the adjacent sloping ceilings. It can be seen that such a ridge ventilation is made up of a large number of relatively complicated individual parts, which must also be laid with great care. As a result, such ridge ventilation is relatively expensive, which, despite its good effect, prevents widespread use.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine solche Firstentlüftung derart weiterzubilden, daß sie aus einer geringeren Anzahl einfach herzustellender Teile besteht und auch noch nachträglich bei bestehenden Dächern ohne Mühe angebracht werden kann.The invention is therefore based on the object to develop such a ridge ventilation such that it consists of a smaller number of easily manufactured parts and can also be retrofitted to existing roofs with ease.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Spalte zwischen der Firstbohle und den Dacheindeckungsplatten der beidseitig angrenzenden Dachschrägen durch an der Firstbohle befestigte Dichtungsstreifen abgeschlossen sind, welche die Abstandsräume bildende und somit die Einzelkanäle begrenzende in Richtung auf die Abdeckkappen vorstehende Ausprägungen aufweisen, in deren Wandungen die Einzelkanäle und die Abstandsräume verbindende Öffnungen angeordnet sind.This object is achieved according to the invention in that the gaps between the ridge screed and the roof covering plates of the roof slopes adjoining on both sides are completed by sealing strips attached to the ridge screed, which have the spacing spaces and thus delimit the individual channels and protrude in the direction of the cover caps the walls of which are arranged the individual channels and the openings connecting the spacing spaces.

Die Erfindung macht demnach von einer Firstabdeckung mit Dichtungsstreifen Gebrauch, wie sie beispielsweise aus der DE-C-2701 196 bekannt ist. Obwohl bei der bekannten Firstabdeckung die Dichtungsstreifen einen im wesentlichen dichten Abschluß des Dachraums bewirken, läßt sich durch die erfindungsgemäße Ausbildung dieser Dichtungsstreifen eine Firstentlüftung herstellen, welche den Hohlraum unter den Abdeckkappen kreuzende Einzelkanäle aufweist, die zu Luftaufstiegszonen hin offen sind. Es brauchen daher nur die bekannten Dichtungsstreifen durch die nach der Erfindung ausgebildeten Dichtungsstreifen ersetzt zu werden, um eine sehr effektive Firstentlüftung zu erzielen. Die nach der Erfindung ausgebildeten Dichtungsstreifen sind in einfacher Weise herstellbar und ebenso leicht an der Dachbohle anzubringen wie die herkömmlichen Dichtungsstreifen. Daher ist die erfindungsgemäße Firstentlüftung mit sehr geringen Kosten herstellbar und auch bei bestehenden Dächern noch nachträglich leicht anzubringen.The invention accordingly makes use of a ridge cover with sealing strips, as is known, for example, from DE-C-2701 196. Although in the known ridge cover the sealing strips bring about an essentially tight seal of the roof space, the ridge ventilation can be produced by the design of these sealing strips according to the invention, which has individual channels crossing the cavity under the cover caps, which are open to air rise zones. It is therefore only necessary to replace the known sealing strips with the sealing strips designed according to the invention in order to achieve a very effective ridge ventilation. The sealing strips designed according to the invention can be produced in a simple manner and are just as easy to attach to the roof screed as the conventional sealing strips. Therefore, the ridge ventilation according to the invention can be produced at very low cost and can also be easily retrofitted to existing roofs.

Bei einer bevorzugten Ausführungsform der Erfindung reichen die Ausprägungen bis an die Unterseite der Firstkappe, und es sind die Öffnungen in den einander gegenüberliegenden Seitenwänden der Ausprägungen angebracht. In diesem Fall kann die Oberseite der Ausprägungen wenigstens im Bereich der Öffnungen von der zu den Einzelkanälen parallelen Längsmittelebene zu den Seitenwänden hin ansteigen. Auf diese Weise werden gut gegeneinander abgetrennte Einzelkanäle geschaffen, die zu einer maximalen Wirksamkeit der Dachentlüftung führt, und es hat die Profilierung der Oberseite der Ausprägungen eine günstige Wirkung sowohl bezüglich der mechanischen Stabilität als auch der Umlenkung der aufsteigenden Luft in Richtung auf die in den Seitenwänden angeordneten Öffnungen.In a preferred embodiment of the invention, the features extend to the underside of the ridge cap, and the openings are made in the mutually opposite side walls of the features. In this case, the top of the embossments can rise at least in the region of the openings from the longitudinal center plane parallel to the individual channels to the side walls. In this way, well separated individual channels are created, which leads to maximum effectiveness of the roof ventilation, and it has the profiling of the top of the forms a beneficial effect both in terms of mechanical stability and the deflection of the rising air in the direction of those in the side walls arranged openings.

Bei einer bevorzugten Ausführungsform der Erfindung laufen die Ausprägungen in Richtung auf den äußeren Rand der Dichtungsstreifen hin in eine Spitze aus. Auf diese Weise wird die an der Dachschräge anströmende Luft weitgehend wirbelfrei auf die einzelnen Kanäle verteilt. Außerdem entsteht am Einlauf der Einzelkanäle eine düsenartige Verengung, welche im Bereich der Öffnungen der Ausprägungen eine Druckverminderung und damit eine Verbesserung der Entlüftung zur Folge hat.In a preferred embodiment of the invention, the features end in a tip in the direction of the outer edge of the sealing strips. In this way, the air flowing in at the sloping roof is distributed to the individual ducts largely without vortexes. In addition, a nozzle-like narrowing occurs at the inlet of the individual channels, which results in a reduction in pressure in the region of the openings and thus an improvement in the ventilation.

Eine besonders günstige und stabile Ausführung ergibt sich, wenn sich an einen die Öffnungen aufweisenden Abschnitt der Ausprägungen, der zur Oberfläche des Dichtungsstreifen im wesentlichen senkrechte und zueinander parallele Seitenwände aufweist, ein sowohl im Grundriß als auch im Querschnitt dreieckiger Abschnitt mit nach außen abnehmender Höhe anschließt. Dabei können die Dichtungsstreifen im Bereich des Überganges von dem die Öffnungen aufweisenden Abschnitt zu dem dreieckigen Abschnitt nach unten abgewinkelt sein. Auf diese Weise ergibt sich auch eine optimale Anpassung des Dichtungsstreifens an die Form der First-Abdeckkappen.A particularly favorable and stable design is obtained if a section of the formations which has the openings and which has side walls which are essentially perpendicular to one another and parallel to the surface of the sealing strip, is followed by a section which is triangular both in plan and in cross section and decreases in height to the outside . The sealing strips can be angled downward in the region of the transition from the section having the openings to the triangular section. This also results in an optimal adaptation of the sealing strip to the shape of the ridge cover caps.

Die Ausprägungen können grundsätzlich bis an den inneren Rand der Dichtungsstreifen reichen, wenn die Dichtungsstreifen mit aneinanderstoßenden Rändern auf der Firstbohle befestigt werden, wie es aus der DE-C-2 701 196 bekannt ist. Bei einer bevorzugten Ausführungsform der Erfindung reichen die Ausprägungen jedoch in Richtung auf den inneren Rand der Dichtungsstreifen nur bis zu einem abgewinkelten Randstreifen, der auf der Oberseite der Firstlatte befestigt ist. Diese Maßnahme erleichtert die Befestigung des Dichtungsstreifens auf der Firstlatte. Der dabei entstehende Abstand zwischen den in Längsrichtung der Kanäle hintereinanderliegenden Ausprägungen ist nicht störend, weil bei der durch die Einzelkanäle erzwungenen Luftströmung eine Querströmung durch diese Zwischenräume hindurch in Längsrichtung des Firstes praktisch nicht auftreten kann. Es bestände aber grundsätzlich auch die Möglichkeit, die Dichtungsstreifen einteilig in der Weise auszubilden, daß sie von der einen bis zur gegenüberliegenden anderen Dachschräge reichen und im Bereich ihrer Mitte auf der Firstbohle befestigt werden.The characteristics can in principle extend to the inner edge of the sealing strips if the sealing strips are attached to the ridge screed with abutting edges, as is known from DE-C-2 701 196. In a preferred embodiment of the invention, however, the characteristics extend towards the inner edge of the Sealing strips only up to an angled edge strip, which is attached to the top of the ridge batten. This measure makes it easier to attach the weather strip to the ridge batten. The distance that arises between the features lying one behind the other in the longitudinal direction of the channels is not disruptive because, in the case of the air flow forced through the individual channels, a transverse flow through these spaces in the longitudinal direction of the ridge can practically not occur. In principle, however, there would also be the possibility of forming the sealing strips in one piece in such a way that they extend from one to the opposite other sloping roof and are fastened to the ridge screed in the region of their center.

Die Dichtungsstreifen sind gewöhnlich an ihren äußeren, auf den Dacheindeckungsplatten anliegenden Rändern mit Ausschnitten versehen, die dem Profil der Dacheindeckungsplatten angepaßt sind, so daß die Dacheindeckungsplatten mit ihren Wülsten in diese Ausschnitte eingreifen. Diese Ausbildung der Dichtungsstreifen erfordert die Bereitstellung unterschiedlicher Ausführungsformen für die verschiedenen, handelsüblichen Dacheindeckungsplatten. Darüberhinaus ist die Lage der Dichtungsstreifen durch die Anordnung der Dacheindeckungsplatten bestimmt. Daher müssen die auf den beiden, an die Firstbohle angrenzenden Dachschrägen angeordneten Dacheindeckungsplatten derart zueinander ausgerichtet sein, daß bei der dadurch bedingten Lage der auf einem gemeinsamen Abschnitt der Firstbohlen aufliegenden Dichtungsstreifen die Ausprägungen und demnach auch die davon begrenzten Einzelkanäle miteinander fluchten, wie es für eine optimale Entlüftung erforderlich ist. Diese Bedingung kann zwar bei neu zu deckenden Dächern eingehalten werden, erfordert jedoch besondere Maßnahmen, die die Dachdeckung erschweren und in der Praxis sicher häufig unterlassen werden. Beim nachträglichen Anbringen einer solchen Firstentlüftung bei einem bestehenden Dach wird diese Bedingung in aller Regel nicht erfüllt sein.The sealing strips are usually provided on their outer edges lying on the roofing panels with cutouts which are adapted to the profile of the roofing panels, so that the roofing panels engage with these beads in their cutouts. This design of the sealing strips requires the provision of different embodiments for the different, commercially available roofing sheets. In addition, the position of the sealing strips is determined by the arrangement of the roofing panels. Therefore, the roof covering plates arranged on the two roof slopes adjacent to the ridge screed must be aligned with each other in such a way that, given the position of the sealing strips lying on a common section of the ridge screed, the characteristics and, accordingly, the individual channels delimited therefrom are aligned, as is the case for one optimal ventilation is required. Although this condition can be met with new roofs to be covered, it requires special measures that make roofing more difficult and are often often avoided in practice. If such a ridge ventilation is retrofitted to an existing roof, this condition will generally not be met.

Um die Firstentlüftung von der Art und Ausführung der Dachdeckung unabhängig zu machen, sind bei einer bevorzugten Ausführungsform der Erfindung zwischen den äußeren Rändern der Dichtungsstreifen und den Dacheindeckungsplatten langgestreckte Dichtungskörper aus einem hochelastischen Material angeordnet, die den Spalt zwischen den Rändern der Dichtungsstreifen und den Dacheindekkungsplatten verschließen.In order to make the ridge ventilation independent of the type and design of the roof covering, in a preferred embodiment of the invention elongated sealing bodies made of a highly elastic material are arranged between the outer edges of the sealing strips and the roof covering plates, which seal the gap between the edges of the sealing strips and the roof covering plates .

Die Dichtungskörper können vorteilhaft aus einem geschäumten Kunststoff, insbesondere einem geschäumten Polyurethan, bestehen und an den Rändern der Dichtungsstreifen befestigt, insbesondere angeklebt sein.The sealing bodies can advantageously consist of a foamed plastic, in particular a foamed polyurethane, and can be attached, in particular glued, to the edges of the sealing strips.

Um eine gute Anpassung an Dacheindekkungsplatten unterschiedlicher Profilierung zu erreichen, weisen bei einer bevorzugten Ausführungsform der Erfindung die Dichtungskörper einen im wesentlichen rechteckigen Querschnitt auf, dessen senkrecht zur Unterseite der Dichtungsstreifen gemessene Höhe etwa doppelt so hoch ist wie dessen Breite. Bei einer praktischen Ausführungsform der Erfindung beträgt die Höhe des Dichtungsstreifens etwa 50 mm. Diese Höhe ist ausreichend, um ein gutes Anschmiegen an die verschiedensten Profile von Dacheindeckungsplatten zu gewährleisten, während andererseits die Breite ein sattes Anliegen der Dichtungskörper an den Dacheindeckungsplatten gewährleistet. Dabei kann es von besonderem Vorteil sein, wenn der Dichtungskörper nicht genau rechteckig ist, sondern eher den Querschnitt eines Parallelogramms aufweist, dessen spitze Winkel an der oberen, inneren und der unteren, äußeren Ecke liegen. Die Dichtungskörper stehen dann leicht nach außen und weisen eine leicht nach unten und außen gerichtete Spitze auf, die das Anschmiegen auch an feine Profilierungen der Dacheindeckungsplatten gewährleistet. Der spitze Winkel des Parallelogramms kann zweckmäßig 75 Grad bis 80 Grad und vorzugsweise 78 Grad betragen.In order to achieve a good adaptation to roof covering panels with different profiles, in a preferred embodiment of the invention the sealing bodies have an essentially rectangular cross section, the height of which is measured perpendicular to the underside of the sealing strips and is approximately twice as large as its width. In a practical embodiment of the invention, the height of the sealing strip is approximately 50 mm. This height is sufficient to ensure that it fits snugly against a wide variety of profiles of roofing panels, while on the other hand the width ensures that the sealing body fits snugly against the roofing panels. It can be particularly advantageous if the sealing body is not exactly rectangular, but rather has the cross section of a parallelogram, the acute angles of which lie at the upper, inner and lower, outer corners. The sealing bodies are then slightly outwards and have a tip pointing slightly downwards and outwards, which also ensures that they fit snugly against the fine profiles of the roof covering panels. The acute angle of the parallelogram can suitably be 75 degrees to 80 degrees and preferably 78 degrees.

Gegenstand der Erfindung ist nicht nur eine Firstentlüftung, sondern auch die zur Herstellung einer solchen Firstentlüftung dienenden Dichtungsstreifen, die vorzugsweise aus Kunststoff bestehen.The invention relates not only to a ridge ventilation, but also to the sealing strips used to produce such a ridge ventilation, which preferably consist of plastic.

Der in Fig. 1 dargestellte Dichtungsstreifen 1 besteht aus einem relativ steifen, aber elastischen Kunststoff. An einen Mittelabschnitt schließen sich zwei Randstreifen 2 und 3 an, die gegenüber dem Mittelabschnitt nach der gleichen Seite hin abgewinkelt sind. Die durch das Abwinkeln der Randstreifen 2 und 3 gebildeten Kanten 4 bzw. 5 verlaufen in Längsrichtung des Dichtungsstreifens 1. Der eine Randstreifen 2 hat eine Breite B, die etwas geringer ist als die halbe Breite üblicher Firstbohlen. In diesem Randstreifen befindet sich eine Anzahl von Nagellöchern 6, die das Aufnageln dieses Randstreifens auf einer Firstbohle erleichtern. Der andere Randstreifen 3 ist durch Ausschnitte 7, deren Abstand gleich dem Abstand der Längswulste von Dacheindeckungsplatten ist, mit denen der Dichtungsstreifen 1 zusammenwirken soll, an das Profil solcher Dacheindeckungsplatten angepaßt. Wie ersichtlich, sind die Ausschnitte 7 symmetrisch zur Mitte des Dichtungsstreifens 1 angeordnet.The sealing strip 1 shown in Fig. 1 consists of a relatively rigid but elastic plastic. A central section is adjoined by two edge strips 2 and 3, which are angled towards the central section on the same side. The edges 4 and 5 formed by angling the edge strips 2 and 3 run in the longitudinal direction of the sealing strip 1. The one edge strip 2 has a width B which is slightly less than half Wide ridge planks. In this edge strip there is a number of nail holes 6, which make it easier to nail this edge strip onto a ridge plank. The other edge strip 3 is adapted to the profile of such roofing panels by cutouts 7, the spacing of which is equal to the spacing of the longitudinal beads of roofing panels with which the sealing strip 1 is intended to cooperate. As can be seen, the cutouts 7 are arranged symmetrically to the center of the sealing strip 1.

Im Bereich seines Mittelabschnittes weist der Dichtungsstreifen nach oben gerichtete Ausprägungen 8 auf, die sich über die ganze Breite des Mittelabschnittes erstrecken und im Abstand parallel zueinander angeordnet sind. Diese Ausprägungen 8 weisen einen ersten Abschnitt 9 auf, dessen Seitenwände 10 sich im wesentlichen senkrecht zur Oberfläche des Dichtungsstreifens 1 erstrecken und mit Öffnungen 11 versehen sind. An diesen ersten Abschnitt schließt sich ein in Richtung auf den äußeren Randstreifen 3 erstreckender zweiter Abschnitt 12 an, der sowohl im Grundriß als auch im Querschnitt eine dreieckige Gestalt hat. Der Mittelabschnitt des Randstreifens ist im Bereich des Überganges von dem ersten Abschnitt 9 der Ausprägungen 8 zu deren zweiten Abschnitt 12 nochmals im gleichen Sinne abgewinkelt wie die Randstreifen 2 und 3.In the region of its central section, the sealing strip has upward-directed features 8 which extend over the entire width of the central section and are arranged parallel to one another at a distance. These features 8 have a first section 9, the side walls 10 of which extend essentially perpendicular to the surface of the sealing strip 1 and are provided with openings 11. This first section is adjoined by a second section 12 which extends in the direction of the outer edge strip 3 and which has a triangular shape both in plan and in cross section. The central section of the edge strip is angled again in the area of the transition from the first section 9 of the features 8 to its second section 12 in the same sense as the edge strips 2 and 3.

Wie Fig. 2 zeigt, werden die in Fig. 1 dargestellten Dichtungsstreifen 1 bei einer Firstäbdekkung so auf eine Firstbohle 21 aufgenagelt, daß die abgewinkelten inneren Randstreifen 2 auf der Oberseite der Firstbohle 21 aufliegen. Dabei fallen die Kanten 4 zwischen dem Mittelabschnitt und dem inneren Randstreifen 2 der Dichtungsstreifen 1 mit den äußeren Kanten 22 der Firstbohle 21 zusammen. Hierdurch wird das Ausrichten der Dichtungsstreifen 1 parallel zur Firstbohle 21 sehr erleichtert. In Längsrichtung der Firstbohle 21 werden die Dichtungsstreifen 1 so aufgelegt, daß die in ihrem äußeren Randstreifen 3 vorgesehenen Ausschnitte 7 die Längswulst 23 der an die Firstbohle 21 angrenzenden Dacheindeckungsplatten 24 aufnehmen. Symmetrisch zur Firstbohle 21 sind über den Dichtungsstreifen 1 mittels durch Nägel 27 befestigte Halteklammern 28 Abdeckkappen 29 angebracht. Die seitlichen Ränder der Abdeckkappe 29 reichen bis nahe an die äußeren Randstreifen 3 der Dichtungsstreifen 1 heran und überdecken die Ausprägungen 8. Wie die Fig. 3 und 4 zeigt, reichen im Idealfall die Ausprägungen 8 bis zur Innenseite der Abdeckkappen 29, so daß die Zwischenräume zwischen den Ausprägungen 8 nicht nur nach unten und zur Seite hin, sondern auch nach oben hin abgeschlossen sind und quer zum First verlaufende Einzelkanäle 13 bilden, die mit ihren stirnseitigen Mündungsöffnungen zu den gegenüberliegenden Dachschrägen hin offen sind. Diese Einzelkanäle stehen über die Öffnungen 11, die sich in den Seitenwänden 10 der Ausprägungen befinden, mit Luftaufstiegszonen in Verbindung, die von den Innenräumen der Ausprägungen 8 gebildet werden, die ihrerseits mit dem sich unterhalb der Dichtungsstreifen befindenden Dachraum in Verbindung stehen. Diese Innenräume der Ausprägungen 8 sind zugleich Abstandsräume zwischen den Einzelkanälen 13.As shown in FIG. 2, the sealing strips 1 shown in FIG. 1 are nailed onto a ridge plank 21 in a ridge beam covering in such a way that the angled inner edge strips 2 rest on the upper side of the ridge plank 21. The edges 4 between the central section and the inner edge strips 2 of the sealing strips 1 coincide with the outer edges 22 of the ridge plank 21. This makes it much easier to align the sealing strips 1 parallel to the ridge plank 21. In the longitudinal direction of the ridge screed 21, the sealing strips 1 are placed in such a way that the cutouts 7 provided in their outer edge strip 3 accommodate the longitudinal bead 23 of the roof covering panels 24 adjacent to the ridge screed 21. Symmetrical to the ridge plank 21, cover caps 29 are attached over the sealing strip 1 by means of retaining clips 28 fastened by nails 27. The lateral edges of the cap 29 extend close to the outer edge strips 3 of the sealing strips 1 and cover the features 8. As shown in FIGS. 3 and 4, the features 8 ideally extend to the inside of the caps 29, so that the gaps between the expressions 8 not only downwards and to the side, but also at the top are closed and form transverse channels to the ridge 13, which are open with their front openings to the opposite roof slopes. These individual channels are connected via the openings 11, which are located in the side walls 10 of the forms, with air rise zones which are formed by the interior spaces of the forms 8, which in turn are connected to the roof space located below the sealing strips. These interiors of the forms 8 are at the same time spaces between the individual channels 13.

Die Wirkungsweise dieser Firstenlüftung beruht darauf, daß praktisch bei jeder Windrichtung die Einzelkanäle von einem Luftstrom durchflossen werden, der aus den Öffnungen 11 in den Wandungen 10 der Ausprägungen Luft mitreißt, die aus dem zu entlüftendem Dachinnenraum abgezogen wird. Diese Entlüftung ist nur in geringem Maß von der Windgeschwindigkeit und Windrichtung abhängig. Zu dieser Unabhängigkeit tragen auch die Luftleitstege 15 bei, die an den Enden der Einzelkanäle 13 parallel zu den Ausprägungen 8 angeordnet sind. Von besonderer Bedeutung ist, daß kein Staudruck auftreten kann, der eine Entlüftung des Daches verhindert. Bei Windstille ist die auf natürlicher Konvektion beruhende Entlüftung nicht gehindert.The operation of this roving ventilation is based on the fact that practically in every wind direction the individual channels are flowed through by an air stream which entrains air from the openings 11 in the walls 10 of the forms, which air is drawn off from the roof interior to be vented. This venting is only slightly dependent on the wind speed and wind direction. The air guiding webs 15, which are arranged at the ends of the individual channels 13 parallel to the forms 8, also contribute to this independence. It is particularly important that no back pressure can occur that prevents the roof from being vented. When there is no wind, the ventilation based on natural convection is not prevented.

Für die Wirkung der Entlüftung ist von besonderem Vorteil, daß die dreieckigen äußeren Abschnitte 12 der Ausprägungen einen stetigen Einlauf der Luft an den Enden der Kanäle bewirken, so daß einerseits eine Wirbelbildung verhindert wird und andererseits ein die Entlüftung fördernder Düseneffekt entsteht. Gleichzeitig wird durch die beschriebene und dargestellte Gestaltung der Ausprägungen eine hohe Formstabilität und eine optimale Anpassung an die Form der First-Abdeckkappen erzielt. In dieser Hinsicht ist es auch günstig, daß bei dem dargestellten Ausführungsbeispiel die Oberseiten 14 der Ausprägungen 8 zu den Seitenwandungen 10 hin ansteigen, wie es insbesondere Fig. deutlich zeigt. Hierdurch wird sowohl eine verbesserte Umlenkung der Luft als auch eine weitere Versteifung der Ausprägung erzielt.It is particularly advantageous for the effect of the ventilation that the triangular outer sections 12 of the forms cause a constant inflow of air at the ends of the channels, so that on the one hand a vortex formation is prevented and on the other hand a nozzle effect promoting ventilation occurs. At the same time, a high degree of dimensional stability and an optimal adaptation to the shape of the ridge cover caps are achieved through the described and illustrated design of the forms. In this regard, it is also favorable that, in the exemplary embodiment shown, the upper sides 14 of the forms 8 rise towards the side walls 10, as is particularly clearly shown in FIG. This achieves both an improved deflection of the air and a further stiffening of the shape.

Da bei dem dargestellten Ausführungsbeispiel die Ausprägungen 8 nur bis zu dem inneren Randstreifen 2 reichen, bleibt zwischen den miteinander fluchtenden Ausprägungen der zu beiden Seiten der Firstbohle 21 angeordneten Dichtungsstreifen 1 ein Zwischenraum 16, der eine Verbindung zwischen benachbarten Einzelkanälen 13 herstellt. Da sich jedoch in allen Einzelkanälen 13 im wesentlichen die gleichen Druckverhältnisse einstellen, kann durch diese Zwischenräume 16 hindurch keine störende Querströmung entstehen. Es wäre jedoch grundsätzlich möglich, die Dichtungsstreifen so auszubilden, daß sich die Ausprägungen 8 bis über die inneren Randstreifen 2 hinweg erstrecken, so daß sie in der hergestellten Firstabdeckung aneinanderstoßen. Ebenso wäre es möglich, den Dichtungsstreifen für die erfindungsgemäße Firstentlüftung so auszubilden, daß er einteilig die Firstbohle 21 überspannt und von der einen Dachschräge bis zur gegenüberliegenden Dachschräge reicht, und einen solchen Dichtungsstreifen mit einer Ausprägung zu versehen, die sich von einem äußeren Randstreifen bis zum anderen erstreckt. Besonders dann wäre es leicht möglich, die Öffnung in den Ausprägungen nicht in deren Seitenwänden anzubringen, sondern an deren Oberseite, insbesondere an einer über der Firstbohle liegenden Stelle. Weiterhin wäre es auch möglich, bei zu beiden Seiten der Firstbohle im Abstand voneinander angeordneten Ausprägungen die Öffnungen in den einander zugewandten Stirnseiten dieser Ausprägungen anzubringen.Since, in the exemplary embodiment shown, the features 8 only extend as far as the inner edge strip 2, an intermediate space 16 remains between the mutually aligned features of the sealing strips 1 arranged on both sides of the ridge screed 21, which creates a connection between adjacent individual channels 13. However, since essentially the same pressure conditions occur in all individual channels 13, no interfering cross-flow can occur through these spaces 16. However, it would in principle be possible to design the sealing strips in such a way that the embossments 8 extend beyond the inner edge strips 2 so that they abut one another in the ridge cover produced. It would also be possible to design the sealing strip for the ridge ventilation according to the invention in such a way that it spans the ridge plank 21 in one piece and extends from one sloping roof to the opposite sloping roof, and such a sealing strips to be provided with an expression which extends from one outer edge strip to the other. In this case, in particular, it would easily be possible to make the opening in the forms not in the side walls, but rather on the upper side thereof, in particular at a point lying above the ridge plank. Furthermore, it would also be possible to make the openings in the mutually facing end faces of these forms, with the mutually spaced forms on both sides of the ridge screed.

Ebenso wie bei dem Dichtungsstreifen nach den Fig. 1 bis 6 besteht auch der in den Fig. 7 und 8 dargestellte Dichtungsstreifen 101 aus einem relativ steifen, aber elastischen Kunststoff, und es schließen sich an einen Mittelabschnitt zwei Randstreifen 102 und 103 an, die gegenüber dem Mittelabschnitt nach der gleichen Seite hin abgewinkelt sind. Die durch das Abwinkeln der Randstreifen 102 und 103 gebildeten Kanten 104 bzw. 105 verlaufen in Längsrichtung des Dichtungsstreifens 101. Der eine Randstreifen 102 hat eine Breite B, die etwas geringer ist als die halbe Breite üblicher Firstbohlen. In diesem Randstreifen befindet sich eine Anzahl von Nagellöchern 106, die das Aufnageln dieses Randstreifens auf einer Firstbohle erleichtern. An der Unterseite des anderen Randstreifens 103 ist ein Dichtungskörper 107 befestigt, der aus geschäumtem Kunststoff besteht. Besonders geeignet ist geschäumtes Polyurethan. Die Höhe H dieses Dichtungskörpers ist größer als die Höhe der Profilierung üblicher Dacheindeckungsplatten, so daß sich der Dichtungskörper infolge seiner hohen Elastizität einwandfrei an die Oberfläche der Dacheinlegungsplatten anlegt und dadurch den Spalt zwischen dem Rand der Dichtungsstreifen 101 und den angrenzenden Dacheindekkungsplatten, die in den Fig. 7 und 8 nicht dargestellt sind, einwandfrei abschließen kann. Für das gute Anliegen des Dichtungskörpers 107 an den Dacheindeckungsplatten ist es besonders günstig, daß der Dichtungskörper bei dem dargestellten Ausführungsbeispiel im Querschnitt nicht genau die Form eines Rechteckes, sondern vielmehr eines Parallelogrammes besitzt. Wie aus Fig. 8 ersichtlich, sind die spitzen Winkel x an der äußeren unteren Ecke und der oberen inneren Ecke des Dichtungskörpers 107 angeordnet, so daß der Dichtungskörper über den Rand des Dichtungsstreifens leicht schräg nach außen vorsteht und außerdem eine nach außen und unten gerichtete Spitze aufweist. Hierdurch ist auch das Anschmiegen an relativ feine Profilierungen der Dacheindeckungsplatten gewährleistet. Bei dem dargestellten Ausführungsbeispiel beträgt der spitze Winkel x 78 Grad. Die Höhe des Dichtungsstreifens H beträgt etwa 50 mm, und es ist die Höhe H etwa doppelt so groß wie die Breite D.Like the sealing strip according to FIGS. 1 to 6, the sealing strip 101 shown in FIGS. 7 and 8 also consists of a relatively stiff but elastic plastic, and two edge strips 102 and 103 adjoin a central section, which are opposite the middle section are angled towards the same side. The edges 104 and 105 formed by angling the edge strips 102 and 103 run in the longitudinal direction of the sealing strip 101. The one edge strip 102 has a width B which is slightly less than half the width of conventional ridge planks. In this edge strip there are a number of nail holes 106 which facilitate the nailing of this edge strip onto a ridge plank. On the underside of the other edge strip 103, a sealing body 107 is attached, which consists of foamed plastic. Foamed polyurethane is particularly suitable. The height H of this sealing body is greater than the height of the profile of conventional roofing panels, so that the sealing body fits perfectly against the surface of the roofing panels due to its high elasticity and thereby the gap between the edge of the sealing strips 101 and the adjacent roofing panels, which are shown in FIGS 7 and 8 are not shown, can conclude perfectly. For the good contact of the sealing body 107 on the roofing panels, it is particularly favorable that the sealing body in the illustrated embodiment does not have exactly the shape of a rectangle in cross section, but rather a parallelogram. As can be seen from Fig. 8, the acute angles x are arranged at the outer lower corner and the upper inner corner of the sealing body 107, so that the sealing body protrudes slightly obliquely outwards over the edge of the sealing strip and also has an outwardly and downwardly directed tip having. This also ensures that the roof cladding clings to relatively fine profiles. In the illustrated embodiment, the acute angle is x 78 degrees. The height of the sealing strip H is approximately 50 mm, and the height H is approximately twice as large as the width D.

Der in den Fig. 7 und 8 dargestellte Dichtungsstreifen wird beim Erstellen der erfindungsgemäßen Firstentlüftung mit dem Randstreifen 102 auf eine nicht näher dargestellte Firstbohle aufgenagelt. Dabei kann die Lage des Dichtungsstreifens sowohl quer zur Firstbohle als auch in deren Längsrichtung ohne Rücksicht auf das Profil der verwendeten Dacheindeckungsplatten frei gewählt werden, so daß eine einwandfreie Abdichtung der Dichtungsstreifen gegenüber den Dacheindeckungsplatten vermittels des Dichtungskörpers 107 erzielt wird und zugleich die Ausprägungen 108 der zu beiden Seiten einer Firstbohle angeordneten Dichtungsstreifen 101 miteinander fluchtend angeordnet werden können, damit auch die von diesen Ausprägungen begrenzten Einzelkanäle 113 miteinander fluchten und von Luft möglichst störungsfrei durchströmt werden können. Die Entlüftung des Dachinnenraumes erfolgt über Öffnungen 111, die in den Seitenwänden 110 der Ausprägungen angebracht sind und die Verbindung zwischen den vom Inneren der Ausprägung 108 gebildeten Luftaufstiegszonen und den Einzelkanälen 113 zwischen den Ausprägungen 108 herstellen. Bei dem dargestellten Ausführungsbeispiel sind in den Seitenwänden 110 jeweils drei solcher Öffnungen 111 angebracht.The sealing strip shown in FIGS. 7 and 8 is nailed to the ridge strip 102 on a ridge plank, not shown, when creating the ridge ventilation according to the invention. The position of the sealing strip can be freely selected both transversely to the ridge screed and in its longitudinal direction, regardless of the profile of the roofing panels used, so that a perfect sealing of the sealing strips against the roofing panels is achieved by means of the sealing body 107 and at the same time the characteristics 108 of the Sealing strips 101 arranged on both sides of a ridge screed can be arranged in alignment with one another, so that the individual channels 113 delimited by these forms are also in alignment with one another and air can flow through them as freely as possible. The roof interior is vented via openings 111, which are provided in the side walls 110 of the features and which establish the connection between the air rise zones formed by the interior of the feature 108 and the individual channels 113 between the features 108. In the illustrated embodiment, three such openings 111 are made in each of the side walls 110.
