Abstract

The invention relates to a ridge and/or hip ventilation element (10) having a central part (11) which can be fixed onto a ridge lath and/or a hip lath (15), and a side part (12). Both sides of the central part (11) are adjoined by side parts (12), which can be placed by their outer edge areas (26) on roof coverings (20), and are so configured as to let air circulate between their edge areas (26) and the central part (11). The side parts (12) have longitudinal folds (18, 19, 28 to 30) in their air-permeable area (16) and/or in their outer edge areas (26). These longitudinal folds extend in the longitudinal direction (17) of the ridge and/or hip ventilation element and create a storage area. The ridge and/or hip ventilation element (10) is thus so configured as to be extractable by its lateral length. By using this ridge and/or hip ventilation element (10), open spaces of different sizes between the ridge lath and the roof covering can be covered in such a way that air circulation is possible between the ridge lath and the roof covering, and the space between the ridge bricks and the roof covering is easy to seal.

Description

First- und/oder Gratbelüftungselement Ridge and / or ridge ventilation element
Die vorliegende Erfindung betrifft ein First- und/oder Gratbelüftungselement , dessen Mittelteil auf einer First- oder Gratlatte befestigbar ist, und dessen beidseitig an den Mittelteil angrenzende Seitenteile mit ihren äußeren Randbereichen auf Dacheindeckungen auflegbar und zwischen ihren Randbereichen und dem Mittelteil luftdurchlässig ausgebildet sind.The present invention relates to a ridge and / or ridge ventilation element, the middle part of which can be fastened on a ridge or ridge slat, and whose side parts adjoining the middle part on both sides with their outer edge regions can be placed on roof coverings and are designed to be air-permeable between their edge regions and the middle part.
Ein derartiges First und/oder Gratbelüftungselement ist aus dem Deutschen Gebrauchsmuster G 94 16 291.3 bekanntgeworden.Such a ridge and / or ridge ventilation element has become known from German utility model G 94 16 291.3.
First- und/oder Gratbelüftungselemente werden im Dachbereich verwendet, um den zwischen der First- oder Gratlatte und den Dacheindeckungen verbleibenden Spalt abzudichten. Dieser Spalt zwischen First- oder Gratlatte und Dacheindeckung verläuft rechts und links der First- oder Gratlatte in Längsrichtung des Dachfirstes. Durch das First- und/oder Gratbelüftungselement wird das Eindringen von Regenwasser, Schnee, Ungeziefer oder Unrat in den Dachinnenraum nach Möglichkeit verhindert. Gleichzeitig soll durch das Firstund/oder Gratbelüftungselement auch eine ausreichende Belüftung des Dachinnenraumes ermöglicht werden, um den Dachstuhl gegen fäulnisbedingte Beschädigungen zu schützen.Ridge and / or ridge ventilation elements are used in the roof area to seal the gap remaining between the ridge or ridge slat and the roof coverings. This gap between the ridge or ridge batten and the roof covering runs to the right and left of the ridge or ridge batten in the longitudinal direction of the roof ridge. The ridge and / or ridge ventilation element prevents rainwater, snow, vermin or debris from entering the roof interior as far as possible. At the same time, the ridge and / or ridge ventilation element should also enable sufficient ventilation of the roof interior to protect the roof structure against damage caused by rot.
Das bekannte First- und/oder Gratbelüftungselement ist einstückig aus einem weichen, offenzelligen Schaumstoff gefertigt . Durch seine fest vorgegebenen geometrischen Abmessungen soll der Spalt zwischen Firstlatte und Dacheindeckung überbrückt werden. Anschließend werden Firstziegel über dem Firstbelüftungselement angeordnet, so daß die Randbereiche des Firstbelüftungselements abdichtend auf die Dacheindek- kung gedrückt werden. Probleme entstehen nun, wenn das Firstbelüftungselement den Spalt zwischen Firstlatte und Dacheindeckung nicht wie vorgesehen überdecken kann. In diesen Fällen treten Dichtungsprobleme in den Randbereichen zwischen Dacheindeckung und Firstziegeln auf. Es können auch Belüftungsprobleme aus der unsachgemäßen Befestigung des Firstbelüftungselements resultieren, da der luftdurchlässige Bereich des Seitenteils unter Umständen auf der Firstlatte oder aber auf der Dacheindeckung zur Anlage kommt. Der luftdurchlässige Bereich kann aus diesem Grund nicht mehr die Funktion der Belüftung des Dachinnenraums erfüllen.The well-known ridge and / or ridge ventilation element is made in one piece from a soft, open-cell foam. Due to its fixed geometric dimensions, the gap between the ridge batten and the roof covering is to be bridged. Then ridge tiles are arranged over the ridge ventilation element so that the edge areas of the ridge ventilation element are pressed onto the roof covering in a sealing manner. Problems now arise when that The ridge ventilation element cannot cover the gap between the ridge batten and the roof covering as intended. In these cases, sealing problems occur in the edge areas between the roof covering and the ridge tiles. Ventilation problems can also result from improper fastening of the ridge ventilation element, since the air-permeable area of the side part may come to rest on the ridge batten or on the roof covering. For this reason, the air-permeable area can no longer fulfill the function of ventilation of the roof interior.
Bei der Errichtung des Dachstuhls kommt es aber immer wieder vor, daß die Abstände zwischen Firstlatte und Dachlatte (bzw. Dacheindeckung) unterschiedlich bemessen sind. Auch kann es bei unpräziser Ausrichtung der Dachlatten vorkommen, daß der Abstand zwischen Firstlatte und Dacheindeckung innerhalb desselben Dachstuhls Schwankungen unterworfen ist.When erecting the roof truss, however, it often happens that the distances between the ridge batten and the roof batten (or roof covering) are dimensioned differently. If the roof battens are not precisely aligned, it can also occur that the distance between the ridge battens and the roof covering is subject to fluctuations within the same roof truss.
Eine mögliche Lösung dieser Probleme könnte darin bestehen, daß der Handwerker Firstbelüftungselemente unterschiedlicher Größe verwendet . Dies ist aber aufwendig durchzuführen und verteuert die Abdichtung zwischen Dacheindeckung und First - ziegeln.A possible solution to these problems could be that the craftsman uses ridge ventilation elements of different sizes. However, this is expensive to carry out and increases the cost of sealing between the roof covering and ridge tiles.
Auch aus der DE 40 01 766 C2 ist ein First- und/oder Gratbelüftungselement bekannt, das in der obengenannten Weise im Firstbereich befestigt werden kann. Die Seitenteile dieses Firstbeluftungselements bestehen aus einem Vliesstoff oder Gewebe, das die Form und Abmessungen des Firstbeluftungselements fest vorgibt. Folglich ist auch dieses First- und/oder Gratbelüftungselement nicht in der Lage, unterschiedliche Abstände zwischen Firstlatte und Dacheindeckung abdecken zu können . Bei einem in der Deutschen Gebrauchsmusterschrift 295 01 242.0 beschriebenen Dichtungsstreifen geht ein Mittelstreifen über zwei längsverlaufende, zwischen sich jeweils einen Abschnitt vorgegebener Länge aufweisende Sicken in einen Seitenstreifen über. Aufgrund dieser Ausbildung weist der Dichtungsstreifen vorgeformte Abknickkanten auf, welche jeweils an unterschiedliche First- und/oder Gratlattenbreiten anpaßbar sind.A ridge and / or ridge ventilation element is also known from DE 40 01 766 C2, which can be fastened in the ridge area in the manner mentioned above. The side parts of this ridge ventilation element consist of a nonwoven fabric or fabric, which specifies the shape and dimensions of the ridge ventilation element. Consequently, this ridge and / or ridge ventilation element is also not able to cover different distances between the ridge batten and the roof covering. In the case of a sealing strip described in the German utility model 295 01 242.0, a median strip merges into a side strip via two longitudinal beads which each have a predetermined length between them. Because of this design, the sealing strip has preformed bend edges, which can each be adapted to different ridge and / or ridge slat widths.
Einfache oder mehrfache Abwinklungen, die an einem Lüftungs- organ nach der Lehre der DE 38 25 348 AI ausgebildet sind, ermöglichen die Ausbildung von Strömungsabrißkanten .Single or multiple bends, which are formed on a ventilation element according to the teaching of DE 38 25 348 AI, enable the formation of flow separation edges.
Längsfalten eines aus der GB 21 55 516 A bekannten Firstbelüftungselements bilden Nutflanken einer Haltenut, in der weitere Komponenten des Firstbelüftungselements befestigt werden können.Longitudinal folds of a ridge ventilation element known from GB 21 55 516 A form groove flanks of a retaining groove in which further components of the ridge ventilation element can be fastened.
Der vorliegenden Erfindung liegt das technische Problem zugrunde, ein First- und/oder Gratbelüftungselement vorzustellen, durch dessen Verwendung unterschiedlich große Freiräume zwischen Firstlatte und Dacheindeckung derart abgedeckt werden können, daß zwischen Firstlatte und Dacheindeckung eine Luftzirkulation möglich ist und der Bereich zwischen Firstziegeln und Dacheindeckung leicht abzudichten ist.The present invention is based on the technical problem of presenting a ridge and / or ridge ventilation element, through the use of which differently sized spaces between the ridge and roof covering can be covered such that air circulation is possible between the ridge and roof covering and the area between ridge tiles and roof covering is easy is to be sealed.
Dieses technische Problem wird erfindungsgemäß dadurch gelöst, daß die Seitenteile in ihrem luftdurchlässigen Bereich und/oder in ihren äußeren Randbereichen mit in Längsrichtung des First- und/oder Gratbelüftungselements verlaufenden Längsfalten versehen sind, die einen Vorratsbereich schaffen, so daß das Firstbeluftungselement in seiner seitlichen Länge ausziehbar gestaltet ist. Durch die Ausbildung der erfindungsgemäßen Längsfalten des Firstbelüftungselements kann das Firstbelüftungselement variabel auf unterschiedliche Abstände zwischen Firstlatte und Dacheindeckung reagieren. Die Falten in Längsrichtung des Firstbelüftungselements gewährleisten, daß die seitliche Erstreckung des Firstbeluftungselements entsprechend angepaßt werden kann und trotzdem der zur Belüftung notwendige Bereich des Seitenteils gegeben ist. Bei einem gegenüber der seitlichen Länge des Firstbelüftungselements kleineren Abstand zwischen Firstlatte und Dacheindeckung können im Firstbelüftungselement neue Falten erzeugt werden, damit sich das Firstbeluftungselement entsprechend seitlich verkürzt. Aus diesem Grund liegt stets der Randbereich dichtend auf der Dacheindeckung auf, während der luftdurchlässige Bereich des Seitenteils des Firstbeluftungselements optimal ausgerichtet zwischen der Firstlatte fixiert ist .This technical problem is solved according to the invention in that the side parts are provided in their air-permeable area and / or in their outer edge areas with longitudinal folds running in the longitudinal direction of the ridge and / or ridge ventilation element, which create a storage area, so that the ridge ventilation element in its lateral length is designed extendable. By designing the longitudinal folds of the ridge ventilation element according to the invention, the ridge ventilation element can react variably to different distances between the ridge slat and the roof covering. The folds in the longitudinal direction of the ridge ventilation element ensure that the lateral extent of the ridge ventilation element can be adapted accordingly and the area of the side part necessary for ventilation is nevertheless provided. If the distance between the ridge batten and the roof covering is smaller than the lateral length of the ridge ventilation element, new folds can be created in the ridge ventilation element so that the ridge ventilation element is shortened laterally accordingly. For this reason, the edge area always lies sealingly on the roof covering, while the air-permeable area of the side part of the ridge ventilation element is fixed optimally aligned between the ridge batten.
Toleranzschwankungen durch die Verwendung unterschiedlicher First- oder Gratlatten und in ihrer ausgerichteten Befestigung zueinander besitzen folglich einen Einfluß auf eine funktionsgerechte Benutzung des Firstbelüftungselements.Tolerance fluctuations due to the use of different ridge or ridge battens and their aligned fastening to one another consequently have an influence on the functional use of the ridge ventilation element.
Erfindungsgemäß können die Längsfalten derart ausgebildet sein, daß entsprechende Abschnitte des Seitenteils der First- und/oder Gratbelüftungselemente zum Firstziegel hin übereinander angeordnet sind oder aber nebeneinander aufgerichtet sind, so daß die Längsfalten zum Firstziegel hinweisen. Die einzelnen Längsfalten müssen auch nicht scharfkantig ausgebildet sein, sondern können auch mit Rundungen gefaltet sein. Wichtig ist es, daß Flächenbereiche des Seitenteils faltenrockartiger Struktur ziehharmonikaartig zusammen- oder auseinandergeschoben werden können. Daher wird erfindungsgemäß unter der Ausbildung von Längsfalten auch ver- standen, daß einzelne Bereiche der Seitenteile des Firstbelüftungselements Wellenberge bzw. Wellentäler bilden. Diese wellenartige Faltung hat den Vorteil, daß sich das Firstbelüftungselement quer zu seiner Längsrichtung variabel anpassen läßt. Beim Auseinanderziehen vergrößert sich der relative Winkel benachbarter Falten bzw. Wellen, und es längt sich dabei dieser Abschnitt des Firstbelüftungselements, ohne daß Materialspannungen auftreten.According to the invention, the longitudinal folds can be designed such that corresponding sections of the side part of the ridge and / or ridge ventilation elements are arranged one above the other towards the ridge tile or are erected next to one another so that the longitudinal folds point towards the ridge tile. The individual longitudinal folds do not have to be sharp-edged either, but can also be folded with curves. It is important that surface areas of the side part of a pleated skirt-like structure can be pushed together or pulled apart like an accordion. Therefore, according to the invention, with the formation of longitudinal folds stood that individual areas of the side parts of the ridge ventilation element form wave crests or wave troughs. This wave-like folding has the advantage that the ridge ventilation element can be variably adjusted transversely to its longitudinal direction. When pulling apart, the relative angle of adjacent folds or waves increases, and this section of the ridge ventilation element lengthens without material stresses occurring.
In einer besonders bevorzugten Ausführungsform des erfin- dungsgemäßen Firstbelüftungselements weisen die äußeren Randbereiche eine Längsfalte auf, die zu einer von der Dacheindeckung wegweisenden Strömungskante aufrichtbar ist . In Verbindung mit der Möglichkeit, das Firstbeluftungselement je nach Bedarf auseinanderziehen zu können, läßt sich eine derartige Strömungskante an beliebiger Stelle mit einer beliebigen Größe zwischen Dacheindeckung und Firstziegel ausbilden. Die Strömungskante kann mit einer geringen Erstrek- kung nach oben zum Firstziegel ragen, sie kann aber auch an dem Firstziegel anliegen. Die Strömungskante verhindert, daß einströmende Luft Schnee, Feuchtigkeit oder Unrat nach innen tragen kann. Der luftdurchlässige Bereich des Firstbelüftungselements bleibt daher stets trocken und durchströmbar, so daß Luft durch den luftdurchlässigen Bereich zirkulieren kann.In a particularly preferred embodiment of the ridge ventilation element according to the invention, the outer edge regions have a longitudinal fold which can be erected to a flow edge pointing away from the roof covering. In connection with the possibility of being able to pull the ridge ventilation element apart as required, such a flow edge can be formed at any point with any size between the roof covering and the ridge tile. The flow edge can protrude upwards to the ridge tile with a slight extension, but it can also rest on the ridge tile. The flow edge prevents incoming air from carrying snow, moisture or debris inside. The air-permeable area of the ridge ventilation element therefore always remains dry and flowable, so that air can circulate through the air-permeable area.
Bei einer weiteren Ausführungsform bestehen die Seitenteile in ihrem luftdurchlässigen Bereich aus einzelnen Filamenten, die zu einem formbaren Gitter oder Gewebe miteinander verbunden sind. Durch die Verwendung der einzelnen Filamente wird ein Bereich des Firstbeluftungselements geschaffen, durch den Luft mit einem hohen Wirkungsgrad strömen kann. Selbst wenn Teilbereiche der Seitenteile mit einer Gitter- Struktur übereinander gefaltet werden, kann trotzdem Luft aus dem Dachinnenbereich nach außen strömen. Im Gegensatz zum Stand der Technik wird durch die vorgegebenen Gitteröffnungen stets eine definierte Möglichkeit für die Luftströmung gewährleistet .In a further embodiment, the side parts in their air-permeable area consist of individual filaments which are connected to one another to form a formable grid or fabric. The use of the individual filaments creates an area of the ridge ventilation element through which air can flow with a high degree of efficiency. Even if partial areas of the side parts with a grid If the structure is folded over each other, air can still flow outwards from the interior of the roof. In contrast to the prior art, the defined grille openings always ensure a defined possibility for the air flow.
Hinsichtlich der Herstellung des erfindungsgemäßen Firstbelüftungselements ist es bevorzugt, daß die äußeren Randbereiche der Seitenteile durch eine Verfestigung der Gitterbereiche gebildet sind. Folglich ist das gesamte Firstbelüftungselement außer dem Mittelteil aus einem Netz oder Gitter gefertigt. Zur Abdichtung zwischen Dacheindeckung und Firstziegeln ist es vorteilhaft, daß auch die äußeren Randbereiche aus dem verformbaren Gitter bestehen. Dies ermöglicht es, die Randbereiche auf die Kontur der Dacheindeckung anzupassen und eine bessere Abdichtung auszubilden. Durch die Verfestigung der Gitterbereiche wird erreicht, daß die Öffnungen zwischen den einzelnen Filamenten beseitigt, eine Dichtfunktion ausgeübt werden kann, aber die Verformbarkeit des Gitters erhalten bleibt .With regard to the manufacture of the ridge ventilation element according to the invention, it is preferred that the outer edge regions of the side parts are formed by solidifying the grille regions. As a result, the entire ridge ventilation element, apart from the central part, is made from a mesh or grid. For sealing between the roof covering and the ridge tiles, it is advantageous that the outer edge areas also consist of the deformable grid. This makes it possible to adapt the edge areas to the contour of the roof covering and to form a better seal. The strengthening of the lattice areas ensures that the openings between the individual filaments are eliminated, a sealing function can be carried out, but the deformability of the lattice is retained.
Bei einer Weiterbildung dieser Ausführungsform besteht die Verfestigung der Randbereiche in einer Beschichtung und/oder Abdeckung der Gitterbereiche mit einer dünnwandigen Folie. Die dünnwandige Folie erfüllt einerseits die Aufgabe, die Gitteröffnungen der Gitterbereiche zu verschließen und andererseits die Stabilität der Randbereiche zu erhöhen. Daher können sich die Randbereiche an unterschiedliche Dachkonturen gut anpassen und die Wirkung einer Abdichtung ermöglichen. Bei einer ersten Realisierung dieser Weiterbildung ist die Folie aus einem Leichtmetall herstellbar. Es ist z.B. denkbar, das Gittergewebe sowohl auf seiner Oberseite als auch an seiner Unterseite mit einer Aluminiumfolie abzudecken. Die beiden Aluminiumfolien können miteinander verklebt werden, so daß das formbare Gitter oder Gewebe in eine Alumi- niumummantelung eingebettet ist. Die Formbarkeit durch die Gitterstruktur bleibt dabei erhalten, auch wenn die Aluminiumfolie aufgebracht ist. Es können natürlich auch Folien aus anderen Metallegierungen verwendet werden.In a further development of this embodiment, the edge regions are solidified by coating and / or covering the grid regions with a thin-walled film. On the one hand, the thin-walled film fulfills the task of closing the lattice openings in the lattice areas and on the other hand increasing the stability of the edge areas. Therefore, the edge areas can adapt well to different roof contours and enable the effect of a seal. In the first implementation of this development, the film can be produced from a light metal. For example, it is conceivable to cover the mesh fabric with an aluminum foil both on its upper side and on its underside. The two aluminum foils can be glued to one another, so that the formable grid or fabric is embedded in an aluminum casing. The formability due to the lattice structure is retained even if the aluminum foil is applied. Of course, foils made of other metal alloys can also be used.
Bei einer anderen Verwirklichung der Beschichtung der Gitterstruktur ist die Folie aus Kunststoff fertigbar. Die Verwendung von Kunststoff hat den Vorteil, daß das Firstbelüftungselement neben seiner kostengünstigen Herstellung aus einem wetterbeständigen Werkstoff gefertigt ist .In another implementation of the coating of the lattice structure, the film can be made of plastic. The use of plastic has the advantage that the ridge ventilation element is made from a weather-resistant material in addition to its cost-effective production.
Der Gitterbereich des First- und/oder Belüftungselements ist vorzugsweise durch Fäden aus einem elastischen Kunststoff oder Metall aufgebaut. Durch derartige Fäden (Filamente) läßt sich das Seitenteil eines Firstbeluftungselements zusätzlich zur Gestaltbarkeit durch die erfindungsgemäßen Längsfalten noch weiter verformen, um eine dreidimensionale Struktur auszubilden, die sich gut an den zu bearbeitenden Dachbereich anpassen kann. Insbesondere können die einzelnen Filamente auch nach der Befestigung des Firstbelüftungselements noch bearbeitet werden. Ähnlich einer Bespannung eines Tennisschlägers können die Filamente gegen einander verschoben werden, um gegebenenfalls korrigieren zu können, daß die Luftdurchlässigkeit beeinträchtigt ist. Bei einer weiteren bevorzugten Ausführungsform ist das First- und/oder Gratbelüftungselement aufrollbar. Dies hat den Vorteil, daß das First- und/oder Gratbelüftungselement zu größeren Rollen aufgerollt werden kann, die sehr einfach und kostengünstig gelagert, transportiert und im Dachbereich befestigt werden können. Es lassen sich Rollen mit einer Länge herstellen, die für ein durchschnittliches Dach ausreicht . Durch das Abrollen des Firstbeluftungselements kann der Handwerker problemlos das Firstbelüftungselement auf der Firstlatte und der Dacheindeckung befestigen.The grid area of the ridge and / or ventilation element is preferably constructed from threads made of an elastic plastic or metal. Such threads (filaments) allow the side part of a ridge ventilation element to be further deformed, in addition to being able to be shaped by the longitudinal folds according to the invention, in order to form a three-dimensional structure which can adapt well to the roof area to be processed. In particular, the individual filaments can still be processed even after the ridge ventilation element has been attached. Similar to the covering of a tennis racket, the filaments can be shifted against one another in order, if necessary, to be able to correct that the air permeability is impaired. In a further preferred embodiment, the ridge and / or ridge ventilation element can be rolled up. This has the advantage that the ridge and / or ridge ventilation element can be rolled up into larger rolls that can be stored, transported and fastened in the roof area very easily and inexpensively. Rolls can be made with a length sufficient for an average roof. By rolling off the ridge ventilation element, the craftsman can easily attach the ridge ventilation element to the ridge batten and the roof covering.
Als Alternative zur aufrollbaren Ausführung kann das erfindungsgemäße Firstbelüftungselement auch durch quer zu seiner Längsrichtung gebildete Falten zu einem Endlos-Firstbelüf- tungselement zusammengelegt werden. Das transport- fertige Firstbeluftungselement liegt dann nicht in zylindrischer Rollenform vor, sondern besitzt quaderförmige Geometrie. Es kann dann besser gestapelt werden. Das Firstbelüftungselement kann dann in einer rechteckigen "Spenderbox" untergebracht werden und als Streifen in entsprechenden Abschnitten entnommen und je nach Bedarf abgetrennt werden.As an alternative to the roll-up design, the ridge ventilation element according to the invention can also be folded into an endless ridge ventilation element by means of folds formed transversely to its longitudinal direction. The ready-to-transport ridge ventilation element is then not in a cylindrical roll shape, but has a cuboid geometry. It can then be stacked better. The ridge ventilation element can then be accommodated in a rectangular "dispenser box" and removed as strips in corresponding sections and separated as required.
Die Befestigung des Firstbelüftungselements läßt sich besonders einfach durchführen, wenn die Unterseite des Mittelteils und/oder der äußeren Randbereiche des Seitenteils mit einer aktivierbaren Klebeschicht versehen sind. Durch das Abziehen einer Schutzfolie über der Klebeschicht kann das Firstbelüftungselement festgeklebt werden. Somit ist das dauerhafte dichte Verschließen des Spaltes zwischen der Firstlatte und der schräggeneigten Dacheindeckung einfach durchzuführen. Zur Verklebung des Firstbelüftungselements sind jegliche Klebetechniken und Klebstoffe denkbar, unter anderem auch die Verwendung von Heißleim. Heißleim verbindet sich unlösbar mit dem Kunststoff des Firstbelüftungselements, so daß auch trotz des Auftretens hoher Temperaturen im Dachbereich eine sichere formschlüssige Verbindung dauerhaft gegeben ist .The ridge ventilation element can be attached particularly easily if the underside of the middle part and / or the outer edge regions of the side part are provided with an activatable adhesive layer. The ridge ventilation element can be glued by pulling off a protective film over the adhesive layer. Thus, the permanent tight sealing of the gap between the ridge slat and the sloping roof covering is easy to carry out. Any adhesive techniques and adhesives are conceivable for gluing the ridge ventilation element, including the use of hot glue. Hot glue connects is inseparable from the plastic of the ridge ventilation element, so that a secure positive connection is permanently provided even in spite of the occurrence of high temperatures in the roof area.

Die Erfindung ist in den Figuren schematisch dargestellt, so daß die wesentlichen Merkmale der Erfindung gut zu erkennen sind. Die Darstellungen sind nicht notwendigerweise maßstäblich zu verstehen.The invention is shown schematically in the figures, so that the essential features of the invention can be clearly seen. The representations are not necessarily to be understood to scale.
Die Fig. 1 zeigt ein Firstbelüftungselement 10, wie es beispielsweise im Firstbereich eines Dachstuhls angeordnet ist. Das Firstbeluftungselement 10 besitzt ein Mittelteil 11 und daran angrenzende Seitenteile 12. Im befestigten Zustand des Firstbelüftungselements 10 liegt das Mittelteil 11 mit seiner Unterseite 13 auf der Oberseite 14 einer Firstlatte 15 auf. An seiner Unterseite 13 besitzt das Mittelteil 11 eine Klebeschicht, so daß das Mittelteil 11 auf der Firstlatte 15 dauerhaft und sicher fixiert ist .1 shows a ridge ventilation element 10, as is arranged, for example, in the ridge area of a roof structure. The ridge ventilation element 10 has a middle part 11 and adjoining side parts 12. When the ridge ventilation element 10 is fastened, the underside 13 of the middle part 11 lies on the top 14 of a ridge batten 15. On its underside 13, the middle part 11 has an adhesive layer, so that the middle part 11 is permanently and securely fixed on the ridge batten 15.
An das Mittelteil 11 grenzen luftdurchlässige Bereiche 16 des Seitenteils 12 an. Die luftdurchlässigen Bereiche 16 besitzen zwei in Längsrichtung 17 des Firstbelüftungselements 10 verlaufende Längsf lten 18 und 19. Aufgrund der Ausbildung der Längsfalten 18 und 19 kann der Bereich 16 quer zur Längsrichtung 17 auseinander gefaltet werden. Die Erstreckung des Firstbelüftungselements 10 quer zur Längsrichtung 17 kann daher verändert werden. Durch die Ausbildung noch weiterer Längsfalten 18 und 19 läßt sich diese Funktion noch verstärken. Es lassen sich unterschiedliche Abstände zwischen der Firstlatte 15 und einer Dacheindek- kung 20 überbrücken.Air-permeable regions 16 of the side part 12 adjoin the middle part 11. The air-permeable regions 16 have two longitudinal folds 18 and 19 running in the longitudinal direction 17 of the ridge ventilation element 10. Due to the design of the longitudinal folds 18 and 19, the region 16 can be folded apart transversely to the longitudinal direction 17. The extent of the ridge ventilation element 10 transversely to the longitudinal direction 17 can therefore be changed. This function can be reinforced by the formation of further longitudinal folds 18 and 19. Different distances between the ridge bar 15 and a roof covering 20 can be bridged.
Die Dacheindeckung 20 ist aus einzelnen Dacheindeckungsplat- ten gebildet und liegt auf Dachlatten 21 und 22 auf. Die Dachlatten 21 und 22 sind an den Dachsparren 23 und 24 befestigt. Die Firstlatte 15 ist über den Dachsparren 23 und 24 mit Hilfe eines Firstlattenhalters 25 angeordnet.The roof covering 20 is formed from individual roof covering plates and lies on roof battens 21 and 22. The roof battens 21 and 22 are attached to the rafters 23 and 24. The ridge batten 15 is arranged above the rafters 23 and 24 with the aid of a ridge batten holder 25.
Das Mittelteil 11 des Firstbelüftungselements 10 geht in den luftdurchlässigen Bereich 16 über, an den wiederum ein nicht luftdurchlässiger Randbereich 26 angrenzt. Das Seitenteil 12 setzt sich aus dem luftdurchlässigen Bereich 16 und dem nicht luftdurchlässigen Randbereich 26 zusammen. Der Randbereich 26 ist ebenfalls zusammenfaltbar, so daß seine Länge in Pfeilrichtung 27 ebenfalls variiert werden kann. Zusätzlich sind im Randbereich 26 Querfalten ausgebildet, deren Faltenkanten in Pfeilrichtung 27 verlaufen. Der Randbereich 26 kann deshalb gut an wellenförmige Dachkonturen angepaßt werden.The middle part 11 of the ridge ventilation element 10 merges into the air-permeable region 16, which in turn is adjoined by a non-air-permeable edge region 26. The side part 12 is composed of the air-permeable area 16 and the non-air-permeable edge area 26. The edge region 26 can also be folded up, so that its length can also be varied in the direction of arrow 27. In addition, transverse folds are formed in the edge region 26, the fold edges of which extend in the direction of arrow 27. The edge region 26 can therefore be adapted well to undulating roof contours.
In der Figur sind Längsfalten 28 bis 30 des Randbereichs 26 gezeigt. Es könnten ebenso wie bei dem Bereich 16 auch bei dem Randbereich noch weitere Längsfalten 28 ausgebildet sein. Sowohl der Bereich 16 als auch der Randbereich 26 sind in einem solchen Fall ziehharmonikaartig ausdehnbar. Die durch die Längsfalten 28 bis 30 gebildeten Bereiche können entweder derart zusammengefaltet sein, daß der Randbereich 26 möglichst parallel zur Dacheindeckung 20 ausgerichtet oder aber daß der Randbereich 26 mit einer zum Firstziegel 31 hin ausgerichteten Strömungskante 32 ausgebildet ist. Die Strömungskante 32 verhindert, daß aus dem Bereich der Dacheindeckung 20 Schnee oder Regen unterhalb des Firstziegels 31 bis zum luftdurchlässigen Bereich 16 vordringen kann.In the figure, longitudinal folds 28 to 30 of the edge region 26 are shown. As in the region 16, further longitudinal folds 28 could also be formed in the edge region. In such a case, both the region 16 and the edge region 26 can be expanded like an accordion. The areas formed by the longitudinal folds 28 to 30 can either be folded together in such a way that the edge area 26 is aligned as parallel as possible to the roof covering 20 or that the edge area 26 is formed with a flow edge 32 oriented toward the ridge tile 31. The flow edge 32 prevents snow or rain from the area of the roof covering 20 from penetrating below the ridge tile 31 to the air-permeable area 16.
Der luftdurchlässige Bereich 16 besteht aus einer Vielzahl einzelner Filamente, die zu einem Gitter verbunden sind. Die Filamente bestehen aus elastischen Fäden aus Kunststoff, so daß der Bereich 16 noch zusätzlich verformt werden kann, um an den Bereich zwischen Firstlatte 15 und Dacheindeckung 20 angepaßt zu werden.The air-permeable area 16 consists of a large number of individual filaments which are connected to form a grid. The filaments consist of elastic threads made of plastic, so that the area 16 can be additionally deformed in order to be adapted to the area between the ridge batten 15 and the roof covering 20.
Ein zwischen den Firstziegeln 31 und dem Firstbeluftungselement 10 verbleibender Freiraum 33 bildet eine Strömungs- bzw. Luftaufstiegszone für die aus einem Dachinneren aufsteigende Luft und für die quer zum Dachfirst strömende Luftströmung . In diesem Freiraum 33 sammelt sich die aus dem Dachinneren durch die Bereiche 16 aufsteigende Abluft.A free space 33 remaining between the ridge tiles 31 and the ridge ventilation element 10 forms a flow or air rise zone for the air rising from a roof interior and for the air flow flowing transversely to the roof ridge. The exhaust air rising from the interior of the roof through the areas 16 collects in this free space 33.
Der auf einer Luvseite des Daches ankommende Luftstrom strömt teilweise unterhalb des Ziegelbereichs 34 in den Freiraum 33 hinein. Unterhalb eines Ziegelbereichs 35 kann der Luftstrom aus dem Freiraum 33 wieder austreten und nimmt dabei die sich in dem Freiraum 33 befindende Abluft mit. Andere Teile des Luftstroms werden über den Firstziegel 31 gelenkt und erzeugen auf der Leeseite im Ziegelbereich 35 einen Unterdruck. Folglich wird die in dem Freiraum 33 befindliche Luft unter dem Ziegelbereich 35 abgesaugt, so daß eine gute Entlüftung des Dachinneren gewährleistet ist .The air flow arriving on a windward side of the roof flows partially into the free space 33 below the brick area 34. Below a brick area 35, the air flow can emerge again from the free space 33 and takes with it the exhaust air located in the free space 33. Other parts of the air flow are directed over the ridge tile 31 and generate a negative pressure on the leeward side in the brick area 35. Consequently, the air located in the free space 33 is extracted under the brick area 35, so that good ventilation of the roof interior is ensured.
Für die Entlüftung des Dachinneren ist es vorteilhaft, wenn die Luftströmung in dem Freiraum 33 in Pfeilrichtung 27 erfolgt.For venting the interior of the roof, it is advantageous if the air flow in the free space 33 takes place in the direction of the arrow 27.
Fig. 2 zeigt, wie das Firstbeluftungselement vor seiner Montage transportiert werden kann.Fig. 2 shows how the ridge ventilation element can be transported before it is installed.
Das Firstbelüftungselement 10 besteht aus dem Mittelteil 11 und den Seitenteilen 12. Das Firstbelüftungselement 10 ist symmetrisch aufgebaut, um mit dem Mittelteil auf einer Firstlatte (siehe Fig. 1) befestigt zu werden. Erfindungsgemäß sind aber auch Firstbeluftungselemente vorstellbar, die unsymmetrisch aufgebaut sind bzw. nur zur Abdichtung und Belüftung einer einzigen Dachschräge dienen.The ridge ventilation element 10 consists of the middle part 11 and the side parts 12. The ridge ventilation element 10 is constructed symmetrically in order to be fastened with the middle part on a ridge slat (see FIG. 1). According to the invention, however, ridge ventilation elements are also conceivable which are constructed asymmetrically or only serve to seal and ventilate a single roof slope.
An das Mittelteil 11 grenzen die Seitenteile 12 beidseitig an. Jedes Seitenteil 12 setzt sich wiederum aus einem luftdurchlässigen Bereich 16 und aus einem nicht luftdurchlässigen Bereich 26 zusammen. Der luftdurchlässige Bereich 16 be- steht aus einer Vielzahl einzelner Filamente, die zu einem Netz oder Gitter zusammen verbunden sind. Das Gitter ist in der Fig. 2 lediglich angedeutet.The side parts 12 adjoin the middle part 11 on both sides. Each side part 12 is in turn composed of an air-permeable area 16 and a non-air-permeable area 26. The air-permeable area 16 consists of a large number of individual filaments that are connected to form a network or grid. The grid is only indicated in FIG. 2.
Die Seitenteile 12 des Firstbelüftungselements 10 besitzen Längsfalten 18, 19 und 28 bis 30, so daß die Seitenteile 12 möglichst eben zusammengedrückt werden können. Im befestigten Zustand des Fristbelüftungselements 10 können die Seitenteile 12 expandiert werden, um unterschiedliche Abstände und Zwischenräume zwischen Firstlatte und Dacheindeckung zu überbrücken. In der Figur sind Abschnitte der Seitenteile 12 platt zusammengepreßt, damit das Firstbelüftungselement 10 zu einer Rolle zusammengerollt werden kann. Das Firstbeluf- tungselement 10 ist aus einem elastischen Kunststoff hergestellt. Daher lassen sich die Seitenteile 12 leicht zusammenfalten, auseinanderziehen und gegebenenfalls wieder erneut zusammenfalten. Die Längsfalten 18, 19 und 28 bis 30 können bereits im gefertigten Zustand des Firstbeluftungselements 10 ausgebildet sein, sie können aber auch aufgrund der Verformbarkeit des Materials durch den Handwerker an anderer Stelle der Seitenteile 12 in das Material eingeformt werden. Durch die Ausbildung der Längsfalten 28 bis 30 kann im Randbereich 26 eine unterschiedlich große von dem Randbereich 26 aufragende Strömungskante (siehe Fig. 1) gebildet werden, deren Höhe auf den Freiraum unterhalb des Firstziegels abgestimmt werden kann.The side parts 12 of the ridge ventilation element 10 have longitudinal folds 18, 19 and 28 to 30, so that the side parts 12 can be compressed as flat as possible. When the time-limited ventilation element 10 is fastened, the side parts 12 can be expanded in order to bridge different distances and spaces between the ridge batten and the roof covering. In the figure, sections of the side parts 12 are pressed flat together so that the ridge ventilation element 10 can be rolled up into a roll. The ridge ventilation element 10 is made of an elastic plastic. Therefore, the side parts 12 can be easily folded, pulled apart and, if necessary, folded again. The longitudinal folds 18, 19 and 28 to 30 can already be formed in the finished state of the ridge ventilation element 10, but they can also be molded into the material elsewhere on the side parts 12 due to the deformability of the material by the craftsman. By forming the longitudinal folds 28 to 30, a differently sized flow edge (see FIG. 1) rising from the edge region 26 can be formed in the edge region 26, the height of which can be matched to the free space below the ridge tile.
Ein Firstbelüftungselement 40 setzt sich nach Fig. 3 wiederum aus einem Mittelteil 41 und daran angrenzenden Seitenteilen 42 zusammen. Das Mittelteil 41 ist eben ausgebildet und aus einem Material hergestellt, das sich von dem Material der Seitenteile 42 unterscheidet. Die Seitenteile 42 setzen sich aus zwei separaten Bestandteilen, einem luftdurchlässi- gen Bereich 43 und einem nichtluftdurchlässigen Randbereich 44, zusammen. Der Bereich 42 und der Randbereich 44 sind aus verschiedenen Werkstoffen gefertigt und miteinander verklebt. Daher kann der Bereich 42 Luftströme sehr gut durchlassen, während der Randbereich 44 eine gute Dichtfunktion ausüben kann .According to FIG. 3, a ridge ventilation element 40 is in turn composed of a central part 41 and adjoining side parts 42. The middle part 41 is flat and made of a material that differs from the material of the side parts 42. The side parts 42 consist of two separate components, an air-permeable gene area 43 and a non-air-permeable edge area 44, together. The area 42 and the edge area 44 are made of different materials and glued together. The area 42 can therefore very well let air flows through, while the edge area 44 can perform a good sealing function.
Der Bereich 42 ist balgartig mit aufragenden Längsfalten zusammengeschoben, um die Erstreckung des Firstbelüftungselements 40 in Pfeilrichtung 45 variieren zu können. Der Randbereich 44 besitzt Querfalten 46 zur Anpassung an wellenförmigen Dacheindeckungen (siehe Figur 1) . Eine Strömungskante 47 kann das Eindringen von Schnee oder Regen verhindern.The area 42 is pushed together like a bellows with upstanding longitudinal folds in order to be able to vary the extent of the ridge ventilation element 40 in the direction of the arrow 45. The edge region 44 has transverse folds 46 for adaptation to undulating roof coverings (see FIG. 1). A flow edge 47 can prevent snow or rain from entering.
Ein First- und/oder Gratbelüftungselement 10 besitzt ein Mittelteil 11, das auf einer First- oder Gratlatte 15 befestigbar ist, und ein Seitenteil 12. Beidseitig grenzen an den Mittelteil 11 Seitenteile 12 an, die mit ihren äußeren Randbereichen 26 auf Dacheindeckungen 20 auflegbar und zwischen ihren Randbereichen 26 und dem Mittelteil 11 luftdurchlässig ausgebildet sind. Die Seitenteile 12 sind in ihrem luftdurchlässigen Bereich 16 und/oder in ihren äußeren Randbereichen 26 mit in Längsrichtung 17 des First- und/oder Gratbelüftungselements 15 verlaufenden Längsfalten 18, 19, 28 bis 30 versehen. Durch die Verwendung des First- und/oder Gratbelüftungselements 10 können unterschiedlich große Frei- räume zwischen Firstlatte und Dacheindeckung derart abgedeckt werden, daß zwischen Firstlatte und Dacheindeckung eine Luftzirkulation möglich ist und der Bereich zwischen Firstziegeln und Dacheindeckung leicht abzudichten ist . A ridge and / or ridge ventilation element 10 has a central part 11, which can be fastened on a ridge or ridge batten 15, and a side part 12 are designed to be air-permeable between their edge regions 26 and the central part 11. The side parts 12 are provided in their air-permeable region 16 and / or in their outer edge regions 26 with longitudinal folds 18, 19, 28 to 30 running in the longitudinal direction 17 of the ridge and / or ridge ventilation element 15. By using the ridge and / or ridge ventilation element 10, differently sized free spaces between the ridge slat and the roof covering can be covered in such a way that air circulation is possible between the ridge slat and the roof covering and the area between the ridge tiles and the roof covering can be easily sealed.
