DachelementRoof element
Die Erfindung betrifft ein Dachelement, das an seinen Seitenrändern und an seinem firstseitigen Rand von Dacheindeckungsplatten überdeckbar ist und im Bereich seines firstseitigen Endabschnitts zumindest eine etwa rechtwinklig von seiner Oberseite ausgehende und an die Unterseite der firstseitig überdeckenden Dacheindeckungsplatte anlegbare Dichtung aufweist.The invention relates to a roof element that can be covered by roof covering panels on its side edges and on its ridge-side edge and has in the region of its ridge-side end section at least one seal that extends approximately at right angles from its top side and can be applied to the underside of the roof covering panel that covers the ridge side.
Aus der DE 39 14 025 AI ist ein Dachelement bekannt, das zu einer in ein Schrägdach einbaubaren Lüftungsvorrichtung gehört. Das Dachelement ist als Abdeckung für eine Grundplatte mit einem Austrittsstutzen für ein Lüftungsrohr ausgebildet. Im Bereich seines firstseitigen Endabschnitts weist das Dachelement zumindest eine etwa rechtwinklig von seiner Oberseite ausgehende Dichtung auf, die als elastisch verformbarer Schaumkunststoffkeil ausgebildet ist. Das Dachelement ist beim Einbau in das Schrägdach an seinen Seitenrändern und an seinem firstseitigen Rand von Dacheindeckungsplatten überdeckbar, wobei die Dichtung an die Unterseite der das Dachelement firstseitig überdeckenden Dacheindeckungsplatte anlegbar ist.From DE 39 14 025 AI a roof element is known which belongs to a ventilation device which can be installed in a sloping roof. The roof element is designed as a cover for a base plate with an outlet connection for a ventilation pipe. In the area of its ridge-side end section, the roof element has at least one seal that extends approximately at right angles from its top, which is designed as an elastically deformable foam plastic wedge. When installed in the sloping roof, the roof element can be covered by roof covering plates on its side edges and on its ridge-side edge, the seal being able to be placed on the underside of the roof covering plate covering the roof element on the ridge side.
Beim Auflegen einer stark profilierten Dacheindeckungsplatte auf den Schaumkunststoff eil wird dieser zusammengedrückt, so daß er im Bereich der Wasserläufe an der Unterseite der Dacheindeckungsplatte anliegt. Im Bereich der hohenWhen placing a strongly profiled roof covering plate on the foam plastic, this is pressed together so that it lies in the area of the watercourses on the underside of the roof covering plate. In the area of high
Mittelkrempe der Dacheindeckungsplatte wölbt sich der Schaumkunststoff geringfügig nach oben zur Mittelkrempe hin aus, liegt jedoch nicht an der Mittelkrempe an. Durch den zwischen Dichtung und Unterseite der Dacheindeckungsplatte bestehenden Spalt können Kleintiere, beispielsweise Vögel und Insekten, in die Dachhaut eindringen. Gleichzeitig begünstigt der Spalt das Eindringen von Regenwasser und Flugschnee in die Dachhaut. Aufgabe der vorliegenden Erfindung ist es, ein Dachelement der eingangs genannten Gattung zu schaffen, das universell zum Einbau in Dächer geeignet ist, auch wenn diese mit stark profilierten Dacheindeckungsplatten eingedeckt werden, und das eine dauerhafte und zuverlässige Abdichtung der Dachhaut garantiert.Middle brim of the roof covering plate, the foam plastic bulges slightly upwards towards the middle brim, but does not lie against the middle brim. The gap between the seal and the underside of the roof covering plate allows small animals, such as birds and insects, to penetrate the roof membrane. At the same time, the gap encourages rainwater and flying snow to penetrate the roof membrane. The object of the present invention is to provide a roof element of the type mentioned, which is universally suitable for installation in roofs, even if they are covered with strongly profiled roofing panels, and which guarantees a permanent and reliable sealing of the roof skin.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Dichtung flüssigkeitsdicht als firstseitige Dichtlippe aus plastisch verformbarem Werkstoff ausgebildet ist und zumindest im Bereich ihres freien Randes gewellt ist, so daß dieser in Längsrichtung streckbar und an die gegenüber der Wurzel der firstseitigen Dichtlippe längere Kontur der Unterseite der firstseitig überdeckenden Dacheindeckungsplatte anpaßbar ist.The object is achieved in that the seal is liquid-tight as a ridge-side sealing lip made of plastically deformable material and is corrugated at least in the area of its free edge, so that it can be stretched in the longitudinal direction and to the longer contour of the underside of the root of the ridge-side sealing lip roof covering plate covering the ridge side is adaptable.
Aufgrund ihrer Ausbildung als Dichtlippe weist die Dichtung neben einer hohen Streckbarkeit in Längsrichtung eine hohe Flexibilität auf, so daß die Dichtung an jeder beliebigen Stelle zwischen ihrer Wurzel und ihrem freien Rand abwinkelbar ist. Beim Auflegen einer stark profiliertenDue to its design as a sealing lip, the seal has a high degree of extensibility in the longitudinal direction and a high degree of flexibility, so that the seal can be bent at any point between its root and its free edge. When laying on a strongly profiled
Dacheindeckungsplatte kann sich die Dichtung beispielsweise im Bereich der Wasserläufe abwinkein und großflächig an die Unterseite der Dacheindeckungsplatte anlegen, während sie im Bereich der Mittelkrempe der Dacheindeckungsplatte noch etwa rechtwinklig von der Oberseite des Dachelements absteht und mit ihrem freien Rand linienförmig an der Unterseite der Dacheindeckungsplatte anliegt.The roof covering plate can, for example, bend the seal in the area of the watercourses and place it extensively on the underside of the roof covering plate, while in the area of the central brim of the roof covering plate it still protrudes approximately at a right angle from the top of the roof element and its free edge lies linearly against the underside of the roof covering plate.
Da die Dichtung aus einem flüssigkeitsdichten Werkstoff besteht, ist ein kapillares Eindringen von Regenwasser und ein Durchfeuchten der Dichtung nicht möglich. Die erfindungsgemäße Dichtung besitzt deshalb gegenüber dem bekannten Schaumkunststoffkeil eine wesentlich längere Lebensdauer, weil dieser aufgrund der offenen Poren des SchaumkunststoffesSince the seal is made of a liquid-tight material, capillary penetration of rainwater and a dampening of the seal is not possible. The seal according to the invention therefore has a significantly longer service life than the known foam plastic wedge, because of this due to the open pores of the foam plastic
Regenwasser schwammartig aufsaugt, durchfeuchtet und durch Fäulnis, Pilzbefall und Frosteinwirkung beschädigt wird. Eine besonders großflächige Überdeckung des Dachelements durch die firstseitige Dacheindeckungsplatte kann erreicht werden, wenn zumindest der firstseitige Endabschnitt des Dachelements die seitlichen Dacheindeckungsplatten zum First hin überragt.Rainwater is absorbed like a sponge, moistened and damaged by putrefaction, fungal attack and frost. A particularly large coverage of the roof element by the ridge-side roof covering plate can be achieved if at least the ridge-side end section of the roof element projects beyond the lateral roof covering plates towards the ridge.
Die firstseitige Dichtlippe kann sich über die gesamte Breite des Dachelements erstrecken.The ridge-side sealing lip can extend over the entire width of the roof element.
Bei einem eingebauten Dachelement kann das Eindringen von Schnee oder Regen im Bereich der seitlichenWith a built-in roof element, snow or rain can penetrate into the side area
Dacheindeckungsplatten verhindert werden, wenn im wesentlichen parallel zu den Seitenrändern des Dachelements verlaufende seitliche Dichtlippen vorgesehen sind, die durch die seitlichen Dacheindeckungsplatten zur Mitte des Dachelements hin abgewinkelt werden und sich an deren Unterseite anlegen.Roof covering plates are prevented if lateral sealing lips are provided which run essentially parallel to the side edges of the roof element and which are angled through the lateral roof covering plates towards the center of the roof element and rest on their underside.
Zum Anformen der firstseitigen Dichtlippe an die firstseitige Dacheindeckungsplatte bzw. der seitlichen Dichtlippen an die seitlichen Dacheindeckungsplatten ist es vorteilhaft, wenn die seitlichen Dichtlippen von der firstseitigen Dichtlippe getrennt sind.To form the ridge-side sealing lip on the ridge-side roof covering plate or the side sealing lips on the side roof covering plates, it is advantageous if the side sealing lips are separated from the ridge-side sealing lip.
Auf der Oberseite des Dachelements können im Bereich der Seitenränder je zwei seitliche Dichtlippen angeordnet sein, so daß zwischen den beiden Dichtlippen ein zusätzlicherTwo side sealing lips can be arranged on the top of the roof element in the area of the side edges, so that an additional one between the two sealing lips

Die seitlichen Dichtlippen können zumindest im Bereich des firstseitigen Endabschnitts im Bereich ihrer freien Ränder gewellt sein, so daß sie in ihrer Längsrichtung streckbar und an die gegenüber den Wurzeln der seitlichen Dichtlippen längere Kontur der seitlichen Dacheindeckungsplatten anpaßbar sind. Dies ist vorteilhaft, wenn die Dacheindeckungsplatten an ihrer Unterseite vorspringende Nasen zum Einhängen an einer Dachlatte aufweisen. Das Dachelement kann ebenfalls an einer Dachlatte einhängbar sein. Hierzu kann in den firstseitigen Endabschnitt des Dachelement zumindest eine Vertiefung eingeformt sein, die gleichzeitig einen an der Dachlatte einhängbaren Vorsprung und eine Aufnahme für die Nase einer seitlichen Dacheindeckungsplatte bildet.The lateral sealing lips can be corrugated at least in the region of the ridge-side end section in the area of their free edges, so that they can be stretched in their longitudinal direction and can be adapted to the longer contour of the lateral roofing panels compared to the roots of the lateral sealing lips. This is advantageous if the roof covering plates have projecting lugs on their underside for hanging on a roof batten. The roof element can also be hung on a roof batten. For this purpose, at least one recess can be formed in the ridge-side end section of the roof element, which at the same time forms a projection that can be hung on the roof batten and a receptacle for the nose of a lateral roof covering plate.
Das Dachelement wird beim Einbau mit seinem traufseitigen Endabschnitt auf die Oberseite einer traufseitig verlegten Dacheindeckungsplatte aufgelegt. Das Dachelement inDuring installation, the roof element is placed with its eaves-side end section on the top of a roof covering plate laid on the eaves side. The roof element in

Ein Abheben des traufseitigen Endabschnitts von der traufseitigen Dacheindeckungsplatte bei Sturm kann verhindert werden, wenn auf der Unterseite des Dachelements am traufseitigen Endabschnitt ein streckbares Band aus Metall und/oder ein selbstklebendes Dichtungsband angeordnet ist. Das streckbare Band kann als gewelltes oder geschlitztes Bleiband ausgebildet sein.Lifting of the eaves-side end section from the eaves-side roof covering plate during a storm can be prevented if a stretchable metal band and / or a self-adhesive sealing band is arranged on the underside of the roof element on the eaves-side end section. The stretchable tape can be designed as a corrugated or slotted lead tape.
Das Dachelement kann in seiner Gesamtheit aus einem plastisch verformbaren Material bestehen. Eine formstabilere Ausführung des Dachelements ergibt sich, wenn das Dachelement als Abdeckung einer das Dachelement versteifenden Grundplatte ausgebildet ist. Die Grundplatte kann einen die Dachfläche überragenden Stutzen und das Dachelement eine den Stutzen aufnehmende Durchlaßöffnung aufweisen, so daß Antennenmasten, Dunstrohre, Kaminrohre oder Stützen für Dachaufbauten durch das Dachelement hindurch zur Oberseite des Daches geführt werden können.The roof element as a whole can consist of a plastically deformable material. A more dimensionally stable design of the roof element results if the roof element is designed as a cover for a base plate stiffening the roof element. The base plate can have a nozzle projecting above the roof surface and the roof element can have a passage opening which receives the nozzle, so that antenna masts, extractor pipes, chimney pipes or supports for roof structures can be guided through the roof element to the top of the roof.
