Description

Die Erfindung bezieht sich auf ein Dachbelüftungselement mit den Dachpfannen zugeordneter, in Richtung der Dachneigung liegender Luftdurchtrittsöffnung.The invention relates to a roof ventilation element with the roof tiles assigned air passage opening lying in the direction of the roof pitch.

Ein Dachbelüftungselement dieser Art ist durch die DE-OS 31 18 468 bekannt. Konkret handelt es sich dort um eine in die Dachpfannenreihe eingeschaltete Lüfterpfanne als sogenannte Lüftungsgaube. Letztere besitzt eine von einer Haube überfangene, traufenseitige Luftdurchtrittsöffnung. Die Lüfterpfanne wird im Bereich jeweils einer Durchbrechungsstelle einer Unterspannbahn angeordnet, so daß die Zone zwischen bspw. einer Wärmedämmschicht und der Dacheindeckung Luftzirkulation ermöglicht. Solche Lüftungsgauben stehen aber optisch meist auffällig vor, so daß das ansonsten gleichmäßige Bedachungsbild gestört ist. Außerdem bilden größere Überstände bei Wind eine oft störende Geräuschquelle.A roof ventilation element of this type is known from DE-OS 31 18 468. Specifically, there is a fan pan switched on in the roof tile row as a so-called ventilation dormer. The latter has an air passage opening covered by a hood. The fan pan is arranged in the area of a break-through point of a sarking membrane, so that the zone between, for example, a thermal insulation layer and the roof covering enables air circulation. Such ventilation dormers are usually visually conspicuous, so that the otherwise uniform roof pattern is disturbed. In addition, larger protrusions in the wind are an often annoying source of noise.

Aufgabe der Erfindung ist es, ein Dachbelüftungselement zu schaffen, welches bei einfacher, gebrauchsstabiler Ausbildung die Homogenität des Dachpfannen-Überlappungsbildes nicht mehr so augenfällig stört.The object of the invention is to provide a roof ventilation element which, with a simple, stable design, does not disturb the homogeneity of the roof tile overlap image so conspicuously.

Gelöst ist diese Aufgabe durch die im Anspruch 1 angegebene Erfindung.This object is achieved by the invention specified in claim 1.

Die Unteransprüche sind vorteilhafte Weiterbildungen des erfindungsgemäßen Dachbelüftungselements.The subclaims are advantageous developments of the roof ventilation element according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßes Dachbelüftungseiement von erhöhtem Gebrauchswert erzielt: Durch Einsatz solcher nun sogar kleiner auszubildenden Dachpfannen-Distanzstücke liegt eine optisch weit unauffälligere Belüftungseinrichtung vor, die sich durchgehend reihenförmig ausgerichtet über die ganze Breite des Daches erstreckt. Der die Dachpfannen-Distanzstücke aufnehmende Überlappungsbereich braucht lediglich leicht geöffnet zu werden durch Heben der oberen Dachpfanne. Er unterscheidet sich nach der Bestückung in der Neigungslage kaum von der normalen Eindeckungsstruktur. Die Dachpfannen selbst bleiben in ihrer Form unverändert. Die baulichen Mittel sind einfach und zweckmäßig. Das Dachpfannen-Distanzstück wird an der Oberkante der unteren Dachpfanne befestigt, das Überlappungsende der oberen Dachpfanne wird dabei in Abstandsstellung zur Oberseite der unteren Dachpfanne gehalten. Die Luftdurchtrittsöffnung befindet sich in den Stützwänden des Elementes. Es handelt sich dabei um kastenförmige Grundkörper in Anpassung an die Struktur des jeweiligen Pfannentyps. Dabei ist es weiter von Vorteil, daß das Dachpfannen-Distanzstück die Unterkante der oberen Dachpfanne verhakend umgreift. Der verhakende Umgriff optimiert die Fixierung des Distanzstückes. Wird dabei weiter so vorgegangen, daß das Dachpfannen-Distanzstück auch die untere Dachpfanne im Bereich der Oberkante fesselnd, zweckmäßig hakenartig übergreift, so erhält das Distanzstück zugleich die Funktion einer die Dachpfannen untereinander verbindenden, S-förmig gestalteten Klammer. In baulicher Hinsicht ist es weiter günstig, daß zwei hintereinanderliegende Stützwände mit in Distanzrichtung zueinander versetzt angeordneten Luftdurchtrittsöffnungen ausgestattet sind, wobei die traufenseitige Stützwand die Luftdurchtrittsöffnung im Bereich der der unteren Dachpfanne zugekehrten Kante besitzt. Die demzufolge höhenversetzt liegende dachfirstseitige Luftdurchtrittsöffnung führt im vom Distanzstück gebildeten Raum praktisch kaminartige Verhältnisse und führt damit zu einer günstigeren Strömung. Andererseits wird verhindert, daß Schlagregen oder Pulverschnee in den zu belüftenden Dach-Zwischenraum gelangt. In vorteilhafter Weise kann jede der Luftdurchtrittsöffnungen sich aus Teilöffnungsquerschnitten zusammensetzen, was den Vorteil einer höheren Stützstabilität bringt und im übrigen zu große zusammenhängende Öffnungen, bspw. als Nistmöglichkeit, vermeidet.As a result of such a design, a generic roof ventilation element of increased utility value is achieved: by using roof tile spacers of this type, which are now even smaller, there is a visually far less conspicuous ventilation device which extends in a row-oriented manner over the entire width of the roof. The overlap area accommodating the roof tile spacers only needs to be opened slightly by lifting the upper roof tile. After the placement in the inclined position, it hardly differs from the normal covering structure. The shape of the roof tiles themselves remains unchanged. The structural means are simple and functional. The roof tile spacer is attached to the upper edge of the lower roof tile, the overlap end of the upper roof tile is held in a spaced position from the top of the lower roof tile. The air passage opening is located in the supporting walls of the element. These are box-shaped basic bodies that adapt to the structure of the respective pan type. It is furthermore advantageous that the roof tile spacer engages around the lower edge of the upper roof tile in a hooked manner. The hooking wrap optimizes the fixation of the spacer. If you proceed further so that the roof tile spacer also engages over the lower roof tile in the area of the upper edge in a captivating manner, expediently hook-like, the spacer also has the function of an S-shaped clip connecting the roof tiles to one another. From a structural point of view, it is furthermore favorable that two support walls lying one behind the other are equipped with air passage openings arranged offset in the distance direction from one another, the support wall on the eaves side having the air passage opening in the region of the edge facing the lower roof tile. The height-offset ridge-side air passage opening leads practically chimney-like conditions in the space formed by the spacer and thus leads to a more favorable flow. On the other hand, driving rain or powder snow is prevented from getting into the roof space to be ventilated. Each of the air passages can advantageously Openings are made up of partial opening cross sections, which has the advantage of greater support stability and, moreover, avoids openings that are too large, for example as a nesting possibility.

Zwischen den zum Dachfirst hin ansteigenden oder konvergierenden Dachsparren 1 und den horizontal verlaufenden, parallel zueinander angeordneten Dachlatten 2 befindet sich eine aus Folienmaterial bestehende Unterspannbahn 3.Between the rafters 1 rising or converging towards the roof ridge and the horizontally running roof battens 2 arranged parallel to one another there is an underlay 3 made of film material.

Die Eindeckung besteht aus Dachpfannen 4, die in bekannter Weise die firstseitigen Dachlattenkanten übergreifen und mit ihrem traufenseitigen Ende die nächstfolgende Dachpfanne 4 überlappen. Zwischen die traufenseitige Dachpfanne und die firstseitig folgende vorletzte Dachpfanne 4 ist ein Belüftungselement eingeschaltet. Letzteres ermöglicht einen Belüftungsstrom zwischen einem Belüftungsraum 5 zwischen Dachpfannen 4 und Unterspannbahn 3. Unterhalb der Unterspannbahn 3 und einer zwischen den Dachsparren 1 angeordneten Wärmedämmschicht 6 liegt ein zweiter Belüftungsraum 7. Beide Belüftungsräume sind durch eine Durchbrechung 8 strömungstechnisch miteinander verbunden. Es handelt sich bezüglich des Belüftungselements um ein Dachpfannen-Distanzstück D.The roofing consists of roof tiles 4, which overlap the ridge-side roof battens in a known manner and overlap the next roof tile 4 with their eaves-side end. Between the The eaves-side roof tile and the second to last roof tile 4 following on the ridge side, a ventilation element is switched on. The latter enables a ventilation flow between a ventilation space 5 between roof tiles 4 and roofing membrane 3. Below the roofing membrane 3 and a thermal insulation layer 6 arranged between the roof rafters 1 there is a second ventilation chamber 7. Both ventilation spaces are connected to one another in terms of flow by an opening 8. With regard to the ventilation element, it is a roof tile spacer D.

Das Dachpfannen-Distanzstück D besteht aus einem Kunststoff-Form-oder Spritzling. Dieser ist im wesentlichen kastenförmig gestaltet. Die Kastenöffnung weist nach unten. Es besteht aus zwei quer zur Dachneigung gerichteten, nach unten schwach divergierenden Stützwänden 9 und 10. Die etwas höher gestaltete Stützwand 9 liegt traufenseitig. Die geschlossene Decke des Distanzstücks besitzt eine dem Pfannentyp angepaßte Struktur, also wellenförmig erhaben vorstehende Partien und rinnenartig gestaltete Zonen. Die in Neigungsrichtung liegende, seitliche Überlappungsstruktur entspricht denen der Dachpfannen.The roof tile spacer D consists of a plastic molded or molded part. This is essentially box-shaped. The box opening points downwards. It consists of two supporting walls 9 and 10 directed transversely to the roof pitch and slightly diverging downwards. The somewhat higher supporting wall 9 is on the eaves side. The closed ceiling of the spacer has a structure adapted to the type of pan, that is, protruding parts with undulating projections and zones shaped like channels. The lateral overlap structure in the direction of inclination corresponds to that of the roof tiles.

Das Distanzstück D hebt das traufenseitige Ende 4' der vorletzten Dachpfannen 4 um ein Maß an, welches etwa der Gesamtdicke einer Dachpfanne 4 entspricht, so daß eine wenig auffällige Unterbrechung des Eindeckungsbildes vorliegt, trotzdem aber zufolge der am Distanzstück D vorgesehenen Luftdurchtrittsöffnungen L eine hinreichende Belüftung erfolgt, zumal sich diese Distanzstücke über die ganze Dachbreite unterbrechungsfrei reihenartig verlegen lassen. Bedarfsweise können auch bei längeren Dächern, wie Schleppdächern oder solchen mit einem Niederlaß mehrere Belüftungsreihen realisiert sein, zweckmäßig die letzte in unmittelbarer Firstnähe.The spacer D lifts the eaves-side end 4 'of the penultimate roof tiles 4 by an amount which corresponds approximately to the total thickness of a roof tile 4, so that there is a less noticeable interruption of the covering picture, but nevertheless adequate ventilation is provided due to the air passage openings L provided on the spacer D. takes place, especially since these spacers can be laid in rows without interruption across the entire roof width. If necessary, even with longer roofs, such as trailing roofs or those with a branch, several ventilation rows can be implemented, the last one in the immediate vicinity of the ridge.

Die Luftdurchtrittsöffnungen sind mit L bezeichnet. Sie befinden sich einerseits in der traufenseitigen Stützwand 9 des Distanzstückes D und andererseits in der firstseitigen Stützwand 10 desselben. Die in der Stützwand 9 angeordnete Luftdurchtrittsöffnung ist von von der unteren Wandkante 9' ausgehenden, nicht allzu tief eingeschnittenen Nischen gebildet, so daß sich die als Ganzes mit L bezeichnete Luftdurchtrittsöffnung praktisch aus einer Anzahl von Teilöffnungsquerschnitten a-d zusammensetzt. Gleiches gilt auch in Bezug auf die Luftdurchtrittsöffnung L in der firstseitigen Stützwand 10, nur daß diese von in Deckennähe liegenden, aus fensterartigen Durchbrechungen gebildet ist und nur drei TQilöffnungsquerschnitte a-c zählt. Die in Strömungsrichtung gesehen in zwei hintereinanderliegenden Stützwänden angeordneten Luftdurchtrittsöffnungen nehmen so eine in ihrer Höhe versetzte Lage ein, wobei die traufenseitige Stützwand 9 die Luftdurchtrittsöffnung L im Bereich der der unteren Dachpfanne zugekehrten Kante 9' besitzt. Der so umgelenkte Strömungsweg ist in Fig. 6 durch x bezeichnet.The air passage openings are designated with L. They are located on the one hand in the eaves-side support wall 9 of the spacer D and on the other hand in the ridge-side support wall 10 of the same. The in the Support wall 9 arranged air passage opening is formed by not too deeply recessed niches starting from the lower wall edge 9 ', so that the air passage opening designated as a whole as L is practically composed of a number of partial opening cross sections ad. The same applies in relation to the air passage opening L in the ridge-side support wall 10, only that it is formed by window-like openings located near the ceiling and only counts three T Q il opening cross sections ac. The air passage openings arranged in two support walls lying one behind the other in the direction of flow thus assume a position which is offset in height, the support wall 9 on the eaves side having the air passage opening L in the region of the edge 9 ′ facing the lower roof tile. The flow path deflected in this way is designated by x in FIG. 6.

Die in Reihe angeordneten Dachpfannen-Distanzstücke D sind mit den in Überlappung tretenden Abschnitten der Dachpfannen befestigungsmittelfrei verbunden derart, daß das Distanzstück D, an der Oberkante 11 der unteren Dachpfanne 4 befestigt, das Überlappungsende 4' der oberen Dachpfanne 4 in Abstandsstellung y zur Oberseite der unteren Dachpfanne 4 hält.The roof tile spacers D, which are arranged in series, are connected to the sections of the roof tiles which overlap in such a way that the spacer D, attached to the upper edge 11 of the lower roof tile 4, the overlap end 4 'of the upper roof tile 4 in the spacing position y from the top of the lower roof tile 4 holds.

Dabei ist weiter so vorgegangen, daß das Dachpfannen-Distanzstück D andererseits die Unterkante 12 der oberen Dachpfanne verhakend umgreift. In diesem Bereich sind zwei Haken 13 angeformt. Der Hakenschaft liegt in der Ebene der traufenseitigen Stützwand 9 und setzt sich über die Decke des Distanzstückes hinaus nach oben hin fort, um mit seinem hakenförmig abgewinkelten Ende von etwa der Schaftlänge über die Dachpfanne 4 zu treten.The procedure here is such that the roof tile spacer D, on the other hand, engages around the lower edge 12 of the upper roof tile in a hooked manner. Two hooks 13 are formed in this area. The hook shank lies in the plane of the support wall 9 on the eaves side and continues upward beyond the ceiling of the spacer in order to step over the roof tile 4 with its hook-shaped angled end of approximately the shaft length.

Eine entsprechende Verhakung ist auch im Bereich der Oberkante 11 vorgesehen. Dort gehen mit 14 bezeichnete, ebenfalls paarig angeordnete Haken 14 von der Unterkante der firstseitigen Stützwand 10 aus. Diese Haken 14 untergreifen sogar noch die Einhängeleiste 15 der Dachpfanne 4, welche Einhängeleiste selbst über die Dachlatte 2 greift.A corresponding hooking is also provided in the area of the upper edge 11. There, designated 14, also paired hooks 14 extend from the lower edge of the ridge-side support wall 10. These hooks 14 even engage under the hanging bar 15 Roof tile 4, which engages itself over the roof batten 2.

Die so gegenläufig offenen Hakenmäuler führen zu einem S-förmigen Verbindungselement für die Dachpfannen, so daß dem Distanzstück insofern eine weitere Funktion zukommt.The hook jaws open in opposite directions lead to an S-shaped connecting element for the roof tiles, so that the spacer has a further function in this respect.

Die Zuordnung der Distanzstücke geschieht in der Weise, daß diese den überlappten Dachpfannen firstseitig aufgeschoben werden. Die nächstfolgende braucht nur mit den Haken 13 verbunden und anderenends in Hintergriffstellung zur Dachlatte 2 gebracht zu werden.The spacers are assigned in such a way that they are pushed onto the overlapping roof tiles on the ridge side. The next following need only be connected to the hook 13 and brought to the roof batten 2 at the other end in the rear grip position.

Die Decke des Distanzstückes D berücksichtigt durch entsprechende Neigungslage den veränderten Neigungswinkel der aufliegenden Dachpfanne. Er beträgt ca. 7".The ceiling of the spacer D takes into account the changed inclination angle of the overlying roof tile by means of a corresponding inclination position. It is approximately 7 ".

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
