Description

Die Erfindung betrifft ein Dach mit einer aus über Zwischenstücke verbundenen Firstpfannen bestehenden Firstabdeckung, wobei die Firstpfannenenden zwischen von den Zwischenstücken auskragenden, der Wölbung der Firstpfannen angepaßten Firstpfannen-Abdeckleisten und Firstpfannen-Auflageleisten aufgenommen und in ihrer Lage gehalten sind.The invention relates to a roof with a ridge cover consisting of ridges connected by intermediate pieces, the ridge pan ends being received and held in their position between ridge pan cantilever ridges that protrude from the intermediate pieces and are adapted to the curvature of the ridge pans.

Ein derartiges Dach ist aus der GB-A-2 105 384 bekannt und weist eine aus Firstpfannen bestehende Firstabdeckung auf, wobei die Firstpfannen über Zwischenstücke miteinander verbunden sind. Diese Zwischenstücke besitzen Aufnahmekanäle für die Aufnahme der Firstpfannenenden. Zwischen den einzelnen Firstpfannen und den angrenzenden Dachpfannen des Daches sind Zwischenräume ausgebildet, die zur Belüftung des Dachinneren dienen.Such a roof is known from GB-A-2 105 384 and has a ridge cover consisting of ridge pans, the ridge pans being connected to one another via intermediate pieces. These intermediate pieces have receiving channels for receiving the ridge pan ends. Spaces are formed between the individual ridge tiles and the adjacent roof tiles, which serve to ventilate the interior of the roof.

Die WO-Ä-8 200 336 zeigt einen Ventilator, dessen Gehäuse einen labyrinthförmigen Luftdurchtrittsweg ausbildet. Ein derartiger Ventilator kann in eine kreisrunde Öffnung eines Flachdaches eingesetzt werden, wobei er in der Öffnung des Daches gehalten wird.WO-A-8 200 336 shows a fan, the housing of which forms a labyrinth-shaped air passage. Such a fan can be inserted into a circular opening in a flat roof, being held in the opening in the roof.

Aus der DE-A-2 451 058 sind Firstlüftungselemente bekannt, wobei mehrere in Dachlängsrichtung mit Abstand zueinander reihenförmig hintereinander angeordnete Einzelkanäle mit zu den gegenüberliegenden Dachschrägen hin offenen stirnseitigen Mündungsöffnungen vorgesehen sind. Von den äußeren Stirnrändern jedes Einzelkanals gehend Deckenwände aus, die mit Abstand vor dem Firstbalken enden. Die einander zugekehrten Endkanten der Deckenwände belassen eine Durchbrechung zwischen sich. Im Bereich der Mündungsquerschnitte des Einzelkanales sind mit Abstand zueinander liegende Luftleitwände vorgesehen, die sich zwischen Boden und Deckenwand erstrecken. Mit zur Halterung der als Einsatzstücke ausgebildeten Einzelkanäle dienen Endabschlußleisten der Dachdeckung. Überfangen sind die Einzelkanäle sodann von einer Firstkappe, die in ihrem Mittelbereich auf dem Firstbalken aufliegt. Zwischen den Einzeikanälen befinden sich Abstandsräume, die als Luftaufstiegszonen wirken. Diese Ausgestaltung erschwert das Anbringen von Dachabdeckungen.From DE-A-2 451 058 ridge ventilation elements are known, in which several individual channels arranged in series in the roof longitudinal direction at a distance from one another are provided with front opening openings that are open towards the opposite roof slopes. Ceiling walls extending from the outer end edges of each individual channel end at a distance from the ridge beam. The facing end edges of the ceiling walls leave an opening between them. In the area of the mouth cross-sections of the single channel, air baffles are provided at a distance from one another, which extend between the floor and the ceiling wall. End cover strips of the roof covering also serve to hold the individual channels designed as insert pieces. The individual channels are then overlaid by a ridge cap, which rests on the ridge beam in its central area. There are spacing spaces between the single channels, which act as air access zones. This configuration makes it difficult to attach roof covers.

Der Erfindung liegt die Aufgabe zugrunde, ein Dach der eingangs genannten Art zu schaffen, das bei guter Belüftung gegen Witterungseinflüsse unempfindlich ist und den Dachinnenraum gegen Niederschläge sicher abschirmt.The invention has for its object to provide a roof of the type mentioned, which is insensitive to weather conditions with good ventilation and reliably shields the interior of the roof against precipitation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zwischenstücke als Firstlüftungselemente mit labyrinthförmigen Luftdurchtrittsweg ausgebildet sind.This object is achieved in that the intermediate pieces are designed as ridge ventilation elements with a labyrinth-shaped air passage.

Zufolge derartiger Ausgestaltung ist das Erstellen der Firstabdeckung erleichtert vornehmbar. Es kann auf handelsübliche Firstpfannen zurückgegriffen werden. Zwischen je zwei Firstpfannen ist das Firstlüftungselement unterzubringen. Das- Firstlüftungselement ist so beschaffen, daß es die Kupplungsverbindung zweier Firstpfannen darstellt. Dieselben werden daher in ihrer Lage stabilisiert. Der labytinthförmige Luftdurchtrittsweg des Firstlüftungselements ist so beschaffen, daß Flugschnee oder Schlagregen nicht in den Dachinnenraum eintreten können. Im übrigen liegt ein guter Abzug der Abluft vor.As a result of such a configuration, the creation of the ridge cover can be carried out more easily. Commercial ridge pans can be used. The ridge ventilation element must be placed between two ridge pans. The ridge ventilation element is designed so that it represents the coupling connection of two ridge pans. Their position is therefore stabilized. The labytinth-shaped air passage of the ridge ventilation element is designed so that flying snow or driving rain cannot enter the interior of the roof. Otherwise there is a good extraction of the exhaust air.

Eine vorteilhafte Weiterbildung ist darin zu sehen, daß jedes Firstlüftungselement einen entsprechend der Wölbung der Firstpfannen gestalteten Innendom aufweist, von dessen Seitenflanken die Firstpfannen-Abdeckleisten auskragen und dessen Oberrand mit Abstand überfangen ist von einer formangepaßten Haube. Die Firstpfannen-Abdeckleisten führen zu einem dichten stirnseitigen Abschluß der Firstpfannen, so daß Feuchtigkeit von oben her nicht in den Dachinnenraum eintreten kann. Dabei ist die den Oberrand des Innendoms mit Abstand überfangende Haube so gestaltet, daß sie in Verbindung mit dem Innendom den labyrinthartigen Luftdurchtrittsweg bildet. Die Dachbe- bzw. - entlüftung kann daher im Gegensatz zu der eingangs beschriebenen DE-A-2451 058 sowohl längs- als auch quergerichtet zum Dachfirst erfolgen.An advantageous further development can be seen in the fact that each ridge ventilation element has an inner dome designed in accordance with the curvature of the ridge pans, from whose side flanks the ridge pan cover strips protrude and the upper edge of which is covered by a shape-adapted hood. The ridge pan cover strips lead to a tight front end of the ridge pan, so that moisture cannot enter the interior of the roof from above. The hood overlapping the upper edge of the inner dome is designed so that it forms the labyrinth-like air passage path in connection with the inner dome. In contrast to the DE-A-2451 058 described at the beginning, the roof ventilation or ventilation can therefore take place both longitudinally and transversely to the roof ridge.

Von Vorteil erweist es sich, daß unter den Firstpfannen-Abdeckleisten die Firstpfannen-Auflageleisten von den Seitenflanken des Innendoms auskragen. Demzufolge brauchen die Firstpfannen nicht gesondert befestigt zu werden. Die Festlegung erfolgt über die Firstpfannen-Auflageleisten, auf welchen sich die Firstpfannen abstützen. Gegen Abheben sind die Firstpfannen von den sie überfangenden Firstpfannen-Abdeckleisten gesichert. Diese Abdeckleisten und Auflageleisten führen in Verbindung mit der Stirnseite der Firstpfannen zu einer labyrinthartigen Dichtung.It proves to be advantageous that under the ridge pan cover strips the ridge pan support strips protrude from the side flanks of the inner dome. As a result, the ridge pans do not need to be attached separately. It is determined using the ridge pan support strips on which the ridge pans are supported. The ridge pans are secured against lifting off by the ridge pan cover strips that overlap them. These cover strips and support strips lead to a labyrinth-like seal in connection with the face of the ridge pan.

Günstige Lüftungsverhältnisse ergeben sich, wenn die Haube jedes Firstlüftungselementes den Innendom allseitig und mit Abstand überfängt.Favorable ventilation conditions result when the hood of each ridge ventilation element overlaps the inner dome on all sides and at a distance.

Die Tatsache, daß die Haube in ihrem Scheitel mit einem Befestigungsschrauben-Durchtrittsloch ausgestattet ist, kommt einer schnellen und dauerhaften Festlegung des Firstlüftungselements sehr entgegen.The fact that the hood is equipped with a fastening screw passage hole in its apex is very convenient for a quick and permanent fixing of the ridge ventilation element.

Die Dichtigkeit wird noch dadurch erhöht, daß jede Firstpfannen-Abdeckleiste bis über eine auf sie zu gerichtete Hauben-Seitenflanke auskragt.The tightness is further increased by the fact that each ridge pan cover strip protrudes beyond a hood side flank directed towards it.

Um eine gewisse Neigung beim Verlegen der Firstpfannen zu erzielen, liegen die Firstpfannen-Auflageleisten auf unterschiedlicher Höhe zueinander.In order to achieve a certain inclination when laying the ridge pans, the ridge pan support strips are at different heights.

Eine vorteilhafte weiterbildung des Daches mit den als Firstlüftungselemente ausgebildeten Zwischenstücken ist gemäß Anspruch 8 gekennzeichnet durch einen mit dem Innendom jedes Firstlüftungselementes in Verbindung stehenden lsolations-Zwischenraum, der von einer mit Durchbrechungen ausgestatteten Unterspannbahn abgeteilt ist, die unter einem traufenseitig verlaufenden Auflager endet, welches als Luftdurchtritts-Schacht und schachteingangsseitig labyrinthartig gestaltet ist. Die traufenseitig durch den Luftdurchtritts-Schacht einströmende Zuluft kann nun den Raum zwischen Dachpfannen und Unterspannbahn als auch den Isolations-Zwischenraum belüften, welche Zuluft dann durch das Firstlüftungselement nach außen tritt.An advantageous further development of the roof with the intermediate pieces designed as ridge ventilation elements is characterized in accordance with claim 8 by an insulation space which is connected to the inner dome of each ridge ventilation element and which is provided with an underlayer equipped with openings is divided into a section that ends under a support on the eaves side, which is designed as an air passage shaft and a labyrinth-like side on the shaft entrance. The supply air flowing in through the air passage shaft on the eaves side can now ventilate the space between the roof tiles and the underlay and the insulation space, which supply air then exits through the ridge ventilation element.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Fig. 1 bis 4 erläutert. Es zeigt :

  • Figur 1 in schematischer Darstellung einen Querschnitt durch ein mit den Firstlüftungselementen ausgestattetes Dach,
  • Figur 2 einen Längsschnitt durch das Dach in der Ebene des Firstbalkens,
  • Figur 3 in größerer Einzeldarstellung einen Längsschnitt durch den Dachfirst im Bereich eines Firstlüftungselements und
  • Figur 4 in größerer Darstellung einen Querschnitt durch den Dachfirst im Bereich eines Lüftungselements.
An exemplary embodiment of the invention is explained below with reference to FIGS. 1 to 4. It shows :
  • 1 shows a schematic illustration of a cross section through a roof equipped with the ridge ventilation elements,
  • FIG. 2 shows a longitudinal section through the roof in the plane of the ridge beam,
  • Figure 3 in a larger detail a longitudinal section through the ridge in the area of a ridge ventilation element and
  • FIG. 4 shows a cross section through the roof ridge in the area of a ventilation element in a larger representation.

Der Firstbalken trägt die Bezugsziffer 1. Dieser dient als Auflager für das obere Ende der in der Dachneigung liegenden Dachsparren 2. Jeweils zwei dieser Dachsparren 2 befinden sich auf gleicher Querschnittsebene. Der Abstand zwischen jeweils zwei benachbarten Dachsparren 2 ist gleich.The ridge beam bears the reference number 1. This serves as a support for the upper end of the rafters 2 lying in the roof pitch. Two of these rafters 2 are located on the same cross-sectional plane. The distance between two adjacent rafters 2 is the same.

Auf den Dachsparren 2 liegt eine Unterspannbahn 3 auf. Zu ihrer Fesselung dienen Konterlatten 4, die in der Dachneigung verlaufen und die die Unterspannbahn 3 zwischen den Dachsparren 2 und sich einklemmen. Das traufenseitige Ende der Unterspannbahn 3 wird überfangen von einem traufenseitig verlaufenden Auflager 5, das als Schacht gestaltet ist. Letzterer verjüngt sich in Strömungsrichtung. Die eingangseitig liegende Labyrinthwand 6 wird von einer Abwinklung der Decke 7 gebildet. Parallel zur Labyrinthwand 6 erstreckt sich eine weitere Labyrinthwand 8, die ihrerseits vom Boden 9 ausgeht. Die Labyrinthwände 6 und 8 sind so beschaffen, daß sie einander überlappen und einen zickzackförmigen Durchtrittsverlauf der Zuluft erzwingen. Das schachtförmige Auflager 5 ist in Traufenrichtung so lang bemessen, daß es endseitig auf den Dachsparren 2 aufliegt. Dementsprechend sind mehrere solcher Auflager 5 in Traufenrichtung hintereinanderliegend angeordnet.A roofing membrane 3 lies on the rafters 2. Counter battens 4, which run in the roof pitch and which clamp the sarking membrane 3 between the rafters 2 and themselves, serve to bind them. The eaves-side end of the underlay 3 is overlaid by a support 5 running on the eaves, which is designed as a shaft. The latter tapers in the direction of flow. The labyrinth wall 6 lying on the input side is formed by angling the ceiling 7. A further labyrinth wall 8 extends parallel to the labyrinth wall 6 and in turn extends from the floor 9. The labyrinth walls 6 and 8 are designed such that they overlap one another and force a zigzag-shaped passage of the supply air. The shaft-shaped support 5 is dimensioned so long in the eaves direction that it rests on the rafters 2 at the end. Accordingly, several such supports 5 are arranged one behind the other in the eaves direction.

Parallel zum Dachfirstbalken 1 sind auf den Konterlatten 4 Dachlatten 10 befestigt, die ihrerseits von den Einhakenden 11 der Dachpfannen 12 übergriffen werden. Die traufenseitig verlaufenden unteren Dachpfannen stützen sich dabei an den Auflagern 5 ab und überragen das Stirnende der Dachsparren um ein gewisses Maß. An diesen Stirnenden sind Halterungen 13 für eine nicht dargestellte Regenrinne befestigt. Hierdurch ist erreicht, daß die Zuluft unterhalb der Regenrinne in das eingangsseitig labyrinthartig gestaltete Auflager 5 einströmt.Parallel to the roof ridge beam 1, 4 roof battens 10 are fastened on the counter battens, which in turn are overlapped by the hooking ends 11 of the roof tiles 12. The lower roof tiles running on the eaves side are supported on the supports 5 and protrude to a certain extent from the front end of the rafters. Brackets 13 for a rain gutter, not shown, are attached to these ends. It is thereby achieved that the supply air flows in below the rain gutter into the labyrinth-like support 5.

Zufolge der traufenseitig angeordneten Auflager 5 enden die Konterlatten 4 mit geringem Abstand vor den Auflagern.As a result of the supports 5 arranged on the eaves, the counter battens 4 end at a short distance in front of the supports.

Die Unterspannbahn 3 besitzt jenseits ihres unter der ersten dem Schacht 5 benachbarten Dachlatte 10 verlaufenden Abschnitts eine von einem aufwärts gerichteten Kragen 14 gefaßte Durchbrechung 15. Der Kragen 14 ist seinerseits an der Unterseite zweier parallel zueinander liegender Dachlatten 10 befestigt. Auf diese Weise wird im Bereich der Durchbrechung 15 ein Dom gebildet, so daß bei undichtem Dach oberhalb der Unterspannbahn 3 befindliches Wasser durch den Schacht 5 abfließt.The sarking membrane 3 has, beyond its section running under the first roof batten 10 adjacent to the shaft 5, an opening 15 surrounded by an upwardly directed collar 14. The collar 14 is in turn fastened to the underside of two roof batten 10 lying parallel to one another. In this way, a dome is formed in the area of the opening 15, so that when the roof is leaking, water located above the roofing membrane 3 flows out through the shaft 5.

Zwischen jeweils zwei Dachsparren 2 ist eine Isolations-Zwischenschicht 16 vorhanden. Deren Dicke ist geringer als die Dicke des Dachsparrens. so daß zwischen Unterspannbahn 3 und lsolations-Zwischenschicht 16 ein Zwischenraum 17 verbleibt.An intermediate insulation layer 16 is present between each two rafters 2. Their thickness is less than the thickness of the rafters. so that a space 17 remains between the underlay 3 and the insulation intermediate layer 16.

Dem Dachfirst ist eine als Ganzes mit 18 bezeichnete Firstabdeckung zugeordnet. Die wesentlichen Bestandteile derselben sind eine von den Dachsparren 2 getragene Firstiatte 19, Firstpfannen 20 und jeweils zwischen zwei Firstpfannen 20 angeordnete Firstlüftungselemente 21.A ridge cover, designated as a whole by 18, is assigned to the ridge. The essential components thereof are a ridge mat 19 carried by the rafters 2, ridge pans 20 and ridge ventilation elements 21 each arranged between two ridge pans 20.

Jedes Firstlüftungselement weist einen entsprechend der Wölbung der Firstpfannen 20 gestalteten Innendom 25 auf. Deren etwa ringabschnittförmig gestaltete Seitenflanken 22 sind an ihren unteren Enden durch Stege 23 verbunden, die auf die Oberfläche der firstseitigen Dachpfannen 12 aufsetzen. Der Oberrand R des Innendoms 25 ist mit Abstand von einer formangepaßten Haube 24 überfangen derart, daß die Haube den Innendom 25 allseitig mit Abstand überfängt. Zu diesem Zweck sind die ringabschnittförmig verlaufenden Hauben-Seitenflanken 26 der Krümmung der Firstpfannen 20 ebenfalls angepaßt derart, daß die unteren Enden der Hauben-Seitenflanken 26 durch Stege 27 untereinander verbunden sind. Auf Distanz wird die Haube 24 von Stützstegen 28 der Seitenflanken 22 des Innendoms 25 gehalten. Die Stützstege 28 sind in geeigneter Weise an der Haube 24 festgelegt, bspw. durch Kunststoffschweißung oder Verklebung. Die Stege 23. 27 und die Seitenflanken 22, 26 überlappen sich unter Bildung einer labyrinthartigen Durchströmöffnung. Diese ist so bemessen, daß weder Schlagregen noch Flugschnee in das Firstlüftungselement 21 eintreten können.Each ridge ventilation element has an inner dome 25 designed in accordance with the curvature of the ridge pans 20. Their approximately flank-shaped side flanks 22 are connected at their lower ends by webs 23 which rest on the surface of the ridge-side roof tiles 12. The upper edge R of the inner dome 25 is overlapped at a distance from a shape-adapted hood 24 such that the hood overlaps the inner dome 25 on all sides at a distance. For this purpose, the hood side flanks 26 running in the form of a ring section are also adapted to the curvature of the ridge pan 20 in such a way that the lower ends of the hood side flanks 26 are connected to one another by webs 27. The hood 24 is held at a distance by support webs 28 of the side flanks 22 of the inner dome 25. The support webs 28 are fixed in a suitable manner on the hood 24, for example by plastic welding or gluing. The webs 23, 27 and the side flanks 22, 26 overlap to form a labyrinth-like flow opening. This is dimensioned such that neither driving rain nor flying snow can enter the ridge ventilation element 21.

Die Haube 24 enthält in ihrem Scheitel 29 ein Durchtrittsloch 30 für eine Befestigungsschraube 31, die in die Firstlatte 19 eingreift und die Stege 23 des Innendoms 25 gegen die benachbarten Dachpfannen 12 verspannt.The hood 24 contains in its apex 29 a through hole 30 for a fastening screw 31 which engages in the ridge batten 19 and braces the webs 23 of the inner dome 25 against the adjacent roof tiles 12.

Von den Seitenflanken 22 des Innendoms 25 gehen Firstpfannen-Abdeckleisten 32, 33 aus, die bis über die auf sie zu gerichtete Hauben-Seitenflanke 26 auskragen. Die Krümmung der Firstpfannen-Abdeckleisten 32, 33 entspricht der Außenkrümmung der Firstpfannen 20.Ridge pan cover strips 32, 33 extend from the side flanks 22 of the inner dome 25 and protrude beyond the hood side flank 26 directed towards them. The curvature of the ridge pan cover strips 32, 33 corresponds to the outer curvature of the ridge pan 20.

Unter den Firstpfannen-Abdeckleisten 32. 33 kragen von den Seitenflanke 22 des Innendoms 25 Firstpfannen-Auflageleisten 34, 35 aus. Deren Außenkrümmung entspricht der Innenkrümmung der Firstpfannen 20. In den von den Abdeckleisten und Auflageleisten gebildeten Innenraum treten die Stirnenden 20' der Firstpfannen 20 ein. Die Unterkante der Firstpfannen endet dicht oberhalb der zugekehrten Dachpfannen 12, so daß die Firstpfannen ohne zusätzliche Mitel gehaltert sind.Under the ridge pan cover strips 32, 33, 25 ridge pan support strips 34, 35 protrude from the side flanks 22 of the inner dome. Their outer curvature corresponds to the inner curvature the ridge pans 20. The front ends 20 'of the ridge pans 20 enter the interior formed by the cover strips and support strips. The lower edge of the ridge tiles ends just above the facing roof tiles 12, so that the ridge tiles are held without additional means.

Die durch den Schacht 5 einströmende Zuluft gelangt gemäß eingezeichneter Pfeile sowohl in den Zwischenraum 17 als auch in den Raum oberhalb der Unterspannbahn 3 und von dort aus zum Dachfirst, von wo aus die Luft gemäß Pfeilrichtung durch die laybrinthartig zueinander stehenden Stege 23 und 27 sowie Seitenflanken 22 und 26 das Firstlüftungselement verläßt. Auf diese Weise wird eine homogene optimale Entlüftung erreicht.The incoming air flowing in through the shaft 5 reaches, according to the arrows, both into the intermediate space 17 and into the space above the roofing membrane 3 and from there to the roof ridge, from where the air according to the direction of the arrow through the webs 23 and 27, which are in the manner of a laybrinth, and side flanks 22 and 26 leaves the ridge ventilation element. In this way a homogeneous optimal ventilation is achieved.

Wie Fig. 3 insbesondere veranschaulicht, erstrecken sich die Firstpfannen-Auflageleisten 34, 35 auf unterschiedlicher Höhe zueinander, so daß die Firstpfannen 20, wenn sie jeweils zwischen zwei Firstlüftungselementen eingespannt sind, einen geneigten Verlauf einnehmen.As particularly illustrated in FIG. 3, the ridge pan support strips 34, 35 extend at different heights from one another, so that the ridge pan 20, when they are each clamped between two ridge ventilation elements, assume an inclined course.
