Die Erfindung betrifft ein Firstflächenelement für ein Reetdach, wobei das Firstflächenelement zwei Schenkelbereiche aufweist.The invention relates to a ridge surface element for a thatched roof, wherein the ridge surface element has two leg regions.

Die DE 10 2005 023 994 B3 offenbart eine Einrichtung zum Verhindern einer Bewuchsbildung und zum Abtöten eines auf einem Reetdach gebildeten Bewuchses, wobei der First des Reetdaches mit einer Dachbahn abgedichtet ist, die mit Heidekraut o.dgl. bedeckt ist, das mittels Maschendraht auf dem First des Reetdaches festgelegt ist. Der Maschendraht ist mittels Spanndrähten auf dem Reetdach befestigt. Diese bekannte Einrichtung weist eine Anzahl länglich streifenförmige Abstandsgitterelemente und ein auf dem jeweiligen Abstandsgitterelement fest angebrachtes, länglich streifenförmiges Metallionen-Erzeugerelement auf. Das jeweilige Abstandsgitterelement beabstandet das zugehörige Metallionen-Erzeugerelement von der Oberfläche des Reetdaches.The DE 10 2005 023 994 B3 discloses a means to prevent fouling and to kill a vegetation formed on a thatched roof, wherein the ridge of the thatched roof is sealed with a roofing sheet that is covered with heather or the like. covered by wire mesh on the ridge of the thatched roof. The wire mesh is fixed by means of tension wires on the thatched roof. This known device has a number of elongated strip-shaped spacer grid elements and a fixedly mounted on the respective spacer grid element, elongated strip-shaped metal ion generator element. The respective spacer grid element spaces the associated metal ion generator element from the surface of the thatched roof.

Aus der DE 10 2005 024 008 B3 ist eine Einrichtung zum Verhindern einer Bewuchsbildung oder zum Abtöten eines Bewuchses auf einem Reetdach bekannt, dessen First mit einer Dachbahn abgedichtet ist, die mit Heidekraut o.dgl. bedeckt ist. Auf der Dachbahn sind länglich streifenförmige Flächenelemente aus einem Metallblech angeordnet, das bei einer Reaktion mit Niederschlagwasser Metallionen bildet. Das jeweilige Flächenelement weist in Firstlängsrichtung orientierte und in Traufrichtung voneinander beabstandete Längsfalten sowie in Traufrichtung orientierte und in Firstlängsrichtung voneinander beabstandete Wasserablaufrinnen auf.From the DE 10 2005 024 008 B3 a device for preventing fouling or for killing a vegetation on a thatched roof is known whose ridge is sealed with a roofing sheet or the like with heather. is covered. On the roof membrane elongated strip-shaped surface elements are arranged from a metal sheet, which forms metal ions in a reaction with precipitation water. The respective planar element has longitudinal folds which are oriented in the first-longitudinal direction and spaced apart from one another in eaves, and also have drainage channels oriented in the direction of eaves and spaced apart from one another in the first longitudinal direction.

Die DE 10 2005 027 624 B3 beschreibt eine Einrichtung zum Verhindern bzw. Abtöten von Bewuchs auf einem Reetdach, wobei auf den Dachlatten des Reetdaches Schilfrohrbündel angebracht sind. Um auch an Problemzonen des Reetdaches, die vom Niederschlagwasser nur eingeschränkt erreicht werden, eine gewünschte Wirkung zu erzielen, sind in die Schilfrohrbündel Halmelemente einsteckbar, die bei einer Reaktion mit Niederschlagwasser einen Bewuchs verhindernde bzw. einen Bewuchs abtötende Metallionen erzeugen.The DE 10 2005 027 624 B3 describes a device for preventing or killing fouling on a thatched roof, with reeds bundles being mounted on the roof battens of the thatched roof. In order to achieve a desired effect even on problem areas of the thatched roof, which are only partially reached by the precipitation water, straw elements can be inserted into the reed bundles, which in a reaction with precipitation water produce a growth-preventing or fouling metal ions.

Bei Reetdächern besteht bislang das Problem, dass sich am First durch die jeweils bestehende Luftfeuchtigkeit ein Kondensat bilden kann. Das Kondensat resultiert in einem vorzeitigen Verrotten des Reetdaches im Bereich seines Firstes. Das gilt insbesondere für Gebäude, die bis unter das Reetdach ausgebaut werden, um zusätzlichen Wohnraum zu schaffen.In the case of thatched roofs, there has been the problem that condensate can form on the ridge due to the prevailing humidity. The condensate results in premature rotting of the thatched roof in the area of its ridge. This is especially true for buildings that are expanded to below the thatched roof to create additional living space.

Der Erfindung liegt die Aufgabe zugrunde, ein Firstflächenelement der eingangs genannten Art zu schaffen, mittels welchem ein vorzeitiges Verrotten des Reetdaches im Bereich seines Firstes vermieden wird.The invention has for its object to provide a ridge surface element of the type mentioned, by means of which premature rotting of the thatched roof in the region of his ridge is avoided.

Mit Hilfe des erfindungsgemäßen Firstflächenelementes ergibt sich zwischen diesem und der Oberfläche des Reetdaches im Bereich seines Firstes zwischen der Luvseite und der Leeseite einer durch Wind bedingten Luftströmung der Vorteil, dass eine Kondensatbildung im Firstbereich eines erfindungsgemäße Firstflächenelemente aufweisenden Reetdaches und somit ein vorzeitiges Verrotten des Reetdaches im Firstbereich verhindert wird. Dabei kann die Luftströmung unter dem Firstflächenelement hindurch und über den Firstbereich des Reetdaches durch eine Wetter bedingte Luftströmung oder durch thermische Aufwinde entlang des Reetdaches bewirkt werden.With the aid of the ridge surface element according to the invention results between this and the surface of the thatched roof in the region of his ridge between the windward side and the leeward side of a wind-induced air flow the advantage that a condensate formation in the ridge region of a ridge roof elements according to the invention having thatched roof and thus premature rotting of the thatched roof in the ridge area is prevented. In this case, the air flow can be effected under the ridge surface element and over the ridge region of the thatched roof by a weather-related air flow or by thermal windings along the thatched roof.

Desgleichen ist es möglich, das erfindungsgemäße Firstflächenelement mit Hilfe einer Ventilatoreinrichtung zwangsweise zu belüften.Likewise, it is possible to forcibly aerate the ridge surface element according to the invention by means of a fan device.

Bei dem erfindungsgemäßen Firstflächenelement kann zwischen den beiden Schenkelbereichen ein Firstkronenbereich vorgesehen sein, der mit den beiden Schenkelbereichen materialeinstückig verbunden ist, wobei die beiden Schenkelbereiche mit dem Firstkronenbereich ein vom First des Reetdaches definiert beabstandetes Profil bilden, um mit dem Firstflächenelement auf dem First des Reetdaches einen Lüftungskanal zu bildet.In the ridge surface element according to the invention, a ridge crown region can be provided between the two leg regions, which form a material integral with the two limb regions, wherein the two limb regions form a profile spaced from the ridge of the thatched roof with the ridge crown region in order to form a ridge surface element on the ridge of the thatched roof Ventilation channel to forms.

Das Firstflächenelement kann ein halbrundes, ein halbelliptisches, ein dreieckiges, ein mehreckiges oder ein beliebig anders gestaltetes Profil besitzen.The ridge surface element may have a semicircular, a semi-elliptical, a triangular, a polygonal or any other designed profile.

Als zweckmäßig hat es sich bei einem Firstflächenelement der oben genannten Art erwiesen, wenn die beiden Schenkelbereiche jeweils mit einem Firstauflagebereich ausgebildet sind, der zur Befestigung des Firstflächenelementes bspw. an der Dachlattung des Reetdaches vorgesehen ist. Die Befestigung des erfindungsgemäßen Firstflächenelementes an Dachlatten des Reetdaches kann bspw. mittels Bindedraht und/oder mittels Befestigungsschrauben erfolgen.It has proven to be useful in a ridge surface element of the above type, when the two leg portions are each formed with a Firstauflagebereich, which is provided for fastening the ridge surface element, for example. At the roof battens of the thatched roof. The attachment of the ridge surface element according to the invention on battens of the thatched roof can be done, for example, by means of binding wire and / or by means of fastening screws.

Der jeweilige Firstauflagebereich kann ebenflächig oder rinnenförmig ausgebildet sein. Dabei kann die jeweilige Rinne bspw. nach oben offen sein. In der jeweiligen Rinne, die ein rundes oder ein eckiges Querschnitts-Profil besitzen kann, kann ein Befestigungsdraht- oder ein Befestigungsstangenelement angeordnet sein. Das Befestigungsdraht- oder Befestigungsstangenelement kann zum Fixieren des Bindedrahtes dienen.The respective first contact area can be planar or channel-shaped. In this case, the respective trough, for example, be open at the top. In the respective gutter, which has a round or an angular cross-sectional profile may have a Befestigungsdraht- or a mounting rod member may be arranged.

Als vorteilhaft hat es sich erwiesen, wenn das Firstflächenelement in Firstlängsrichtung zwei voneinander abgewandte Anschlußränder aufweist, von welchen der eine Anschlußrand mit einer nach außen orientierten Anschlußrinne und der davon entfernte zweite Anschlußrand mit einer nach innen orientierten Anschlußrippe ausgebildet ist. Dabei ist es bevorzugt, wenn die Anschlußrinne eine lichte Breitenabmessung besitzt, die größer ist als die Wanddicke der Anschlußrippe, so dass eine optimale Anpassung an unterschiedliche Reetdach-Firstabschlüsse sowohl in Firstlängsrichtung als auch in Höhenrichtung möglich ist.It has proven to be advantageous if the ridge surface element in the Firstlängsrichtung has two mutually remote terminal edges, of which one terminal edge is formed with an outwardly oriented terminal groove and the second terminal edge remote therefrom with an inwardly oriented terminal rib. It is preferred if the connection channel has a clear width dimension, which is greater than the wall thickness of the connecting rib, so that an optimal adaptation to different thatched ridge ridge finishes both in Firstlängsrichtung and in the height direction is possible.

Besonders zweckmäßig ist es hierbei, wenn die Anschlußrinne an ihrem distalen Außenrand eine Lagerrinne für ein Dichtungsband aufweist. Bei dem Dichtungsband kann es sich bspw. um ein handelsübliches Dichtungs-Quellband handeln. Damit ist eine wetterfeste Abdichtung von aneinander anschließenden Firstflächenelementen auf dem First eines Reetdaches gewährleistbar.It is particularly expedient here if the connection channel has a bearing groove for a sealing strip at its distal outer edge. The sealing tape can be, for example, a commercially available sealing source tape. For a weatherproof seal of adjoining First surface elements on the ridge of a thatched roof is guaranteed.

Das erfindungsgemäße Firstflächenelement kann aus jedem geeigneten temperatur- und druckstabilen, witterungsbeständigen Material bestehen. Hierbei kann es sich um ein Metall, ein Kunststoffmaterial, einen nachwachsenden Rohstoff o.dgl. handeln. Desgleichen ist es möglich, dass das Firstflächenelement ein Basiselement aus einem Kunststoffmaterial und ein mit diesem materialschlüssig verbundenes Deckflächenelement aufweist, das aus einem durch Reaktion mit Niederschlagwasser biozide Metallionen generierenden Metall besteht. Das Deckflächenelement kann zur Oberflächenvergrößerung gewellt und/oder gefaltet und/oder genoppt sein. Zur materialschlüssigen Verbindung des Deckflächenelementes mit dem Basiselement dient zweckmäßigerweise eine Haftvermittlerschicht.The ridge surface element according to the invention may consist of any suitable temperature and pressure-stable, weather-resistant material. This may be a metal, a plastic material, a renewable raw material or the like. act. Likewise, it is possible for the ridge surface element to have a base element made of a plastic material and a cover surface element which is materially connected thereto and which consists of a metal which generates biocidal metal ions by reaction with precipitation water. The cover surface element can be curled and / or folded and / or studded for surface enlargement.

Bei dem Deckflächenelement handelt es sich z.B. um ein dünnes Kupferblech, wobei es sich versteht, dass auch andere Materialien für das Deckflächenelement zur Anwendung gelangen können.The cover sheet is e.g. a thin sheet of copper, it being understood that other materials for the top surface element may be used.

Vorteilhaft kann es sein, wenn am Firstkronenbereich des erfindungsgemäßen Firstflächenelementes eine Scharniereinrichtung vorgesehen ist, die sich in Längsrichtung des Firstkronenbereiches erstreckt. Mit Hilfe der Scharniereinrichtung ist es möglich, das Firstflächenelement problemlos an die jeweiligen baulichen Gegebenheiten des Firstes eines Reetdaches anzupassen. Zu diesem Zwecke ist es sinnvoll, wenn Die Scharniereinrichtung im Mittenbereich des Firstkronenbereiches des Firstflächenelementes vorgesehen ist, um eine Symmetrie zu verwirklichen.It may be advantageous if a hinge device is provided on the ridge crown region of the ridge surface element according to the invention, which extends in the longitudinal direction of the ridge crown region.

Fig.1 verdeutlicht schematisch einen Abschnitt eines Reetdaches 10 mit Dachsparren 12, auf welchen Dachlatten 14 befestigt sind. Auf den Dachlatten 14 ist eine Reetdach-Eindeckung 16 in an sich bekannter Weise befestigt. Auf dem First 18 des Reetdaches 10 ist ein Firstflächenelement 20 angebracht, das zwei seitlich voneinander beabstandete Schenkelbereiche 22 aufweist, die mittels eines Firstkronenbereiches 24 miteinander materialeinstückig verbunden sind. Die beiden Schenkelbereiche 22 sind jeweils mit einer Belüftungszone 26 ausgebildet. Fig.1 schematically illustrates a portion of a thatched roof 10 with rafters 12, on which battens 14 are attached. On the roof battens 14 a thatched roofing 16 is attached in a conventional manner. On the ridge 18 of the thatched roof 10, a ridge surface element 20 is attached, which has two laterally spaced apart leg portions 22, which are connected by means of a ridge crown portion 24 with each other materialeinstückig. The two leg regions 22 are each formed with a ventilation zone 26.

Die beiden Schenkelbereiche 22 und der Firstkronenbereich 24 bilden ein vom First 18 des Reetdaches 10 beabstandetes Profil, so dass das Firstflächenelement 20 auf dem First 18 des Reetdaches 10 einen Lüftungskanal 28 bildet.The two leg regions 22 and the ridge crown region 24 form a profile spaced from the ridge 18 of the thatched roof 10, so that the ridge surface element 20 forms a ventilation channel 28 on the ridge 18 of the thatched roof 10.

Eine durch Wind bedingte Luftströmung, die durch die Pfeillinie 30 angedeutet ist, kann somit von der Luvseite 32 des Reetdaches 10 durch den Lüftungskanal 28 zur Leeseite 34 strömen und dabei aus dem Inneren des Dachraumes durch einen im First 18 des Reetdaches 10 ausgebildeten Spalt 36 aufsteigenden Luft, die durch den Pfeil 38 angedeutet ist, zwangsweise abgeführt werden.

Thus, in the ridge area an air accumulation and thus condensation, which would lead to premature rotting of the covering 16 in the region of the ridge 18, prevented.

Die beiden Schenkelbereiche 22 des Firstflächenelementes 20 sind jeweils mit einem Firstauflagebereich 40 ausgebildet. Die Firstauflagebereiche 40 sind zur Befestigung des Firstflächenelementes 20 an zugehörigen Dachlatten 14 vorgesehen. Diese Befestigung ist durch dünne strichpunktierte Linien 42 schematisch angedeutet.The two leg regions 22 of the ridge surface element 20 are each formed with a ridge support region 40. The Firstauflagebereiche 40 are for attachment of the ridge surface element 20 at associated Roof battens 14 are provided. This attachment is indicated by thin dash-dotted lines 42 schematically.

Wie aus Fig. 2 ersichtlich ist, weist das jeweilige Firstflächenelement 20 in Firstlängsrichtung zwei voneinander abgewandte Außenränder 44 und 46 auf. Der erste Außenrand 44 ist mit einer nach außen orientierten Anschlußrinne 48 und der davon entfernte zweite Anschlußrand 46 ist mit einer nach innen orientierten Anschlußrippe 50 ausgebildet. Die jeweilige Anschlußrinne 48 weist eine lichte Breitenabmessung b auf, die wesentlich größer ist als die Wanddicke d der Anschlußrippe 50. Die jeweilige Anschlußrinne 48 ist an ihrem distalen Außenrand 52 mit einer Lagerrinne 54 für ein Dichtungsband 56 ausgebildet. Bei dem Dichtungsband 56 handelt es sich bspw. um ein handelsübliches Quellband, mit welchem eine zuverlässige Abdichtung der zueinander benachbarten, auf dem First 18 in einer Reihe hintereinander angeordneten Firstflächenelemente 20 erreicht wird.How out Fig. 2 can be seen, the respective ridge surface element 20 in the ridge longitudinal direction two opposite outer edges 44 and 46 on. The first outer edge 44 is formed with an outwardly oriented terminal groove 48 and the second terminal edge 46 remote therefrom is formed with an inwardly oriented terminal rib 50. The respective connection channel 48 has a clear width dimension b, which is substantially greater than the wall thickness d of the connecting rib 50. The respective connecting channel 48 is formed at its distal outer edge 52 with a bearing groove 54 for a sealing strip 56. The sealing strip 56 is, for example, a commercially available swelling strip, with which a reliable sealing of the mutually adjacent ridge surface elements 20 arranged on the ridge 18 in a row behind one another is achieved.

Das jeweilige Firstflächenelement 20 weist ein Basiselement 58 aus einem Kunststoffmaterial und ein mit dem Basiselement 58 materialschlüssig verbundenes Deckflächenelement 60 auf. Das Deckflächenelement 60 besteht aus einem durch Reaktion mit Niederschlagwasser biozide Metallionen generierenden Metall, um auf dem Reetdach 10 einen Bewuchs zu verhindern bzw. abzutöten.The respective ridge surface element 20 has a base element 58 made of a plastic material and a cover surface element 60 materially connected to the base element 58. The cover surface element 60 consists of a metal which generates biocidal metal ions by reaction with precipitation water in order to prevent or kill fouling on the thatched roof 10.

Fig.4 verdeutlicht perspektivisch eine Ausbildung des Firstflächenelementes 20, bei dem am Firstkronenbereich 24 eine Scharniereinrichtung 118 vorgesehen ist. Die Scharniereinrichtung 118 erstreckt sich im Mittenbereich des Firstkronenbereiches 24 in Längsrichtung des Firstflächenelementes 20, so dass sich eine symmetrische Ausbildung im Bezug zur Scharniereinrichtung 118 ergibt. Die Schenkelbereiche 22 des Firstflächenelementes 20 sind um die Scharniereinrichtung 118 verschwenkbar. Diese Verschwenkbarkeit ist durch die bogenförmigen Doppelpfeile 120 angedeutet. Durch die Verschwenkbarkeit der Schenkelbereiche 22 ist das Firstflächenelement 20 die jeweiligen baulichen Gegebenheiten eines Firstes eines Reetdaches einfach anpassbar. Figure 4 illustrates in perspective an embodiment of the ridge surface element 20, in which a hinge device 118 is provided on the ridge crown region 24. The hinge device 118 extends in the middle region of the ridge crown region 24 in the longitudinal direction of the ridge surface element 20, so that a symmetrical design with respect to the Hinge 118 results. The leg regions 22 of the ridge surface element 20 are pivotable about the hinge device 118. This pivotability is indicated by the arcuate double arrows 120. Due to the pivotability of the leg regions 22, the ridge surface element 20 is easily adaptable to the respective constructional conditions of a ridge of a thatched roof.
