Description

Die Erfindung betrifft einen Falzdachziegel. Es handelt sich hierbei um einen Falzdachziegel, der die Merkmale des Oberbegriffs des Anspruchs 1 aufweist.The invention relates to a seam roof tile. This is a seam roof tile which has the features of the preamble of claim 1.

Bekannte Dachziegel und Dachsteine dieser Gattung ergeben, wenn sie als Dacheindeckung verlegt sind, ein schuppenartig übereinanderliegendes Bild und leiten in einer oder mehreren breiten Mulden den anfallenden Niederschlag zur Traufe.Known roof tiles and roof tiles of this type, when they are laid as roof cladding, create a scale-like image and guide the precipitation to the eaves in one or more broad hollows.

Die DE 10 2013 010 169 A1 beschreibt einen Falzdachziegel mit einem L-förmigen Wasserfalzbereich und einem L-förmigen Deckfalzbereich, wobei im Wasserfalzbereich jeweils zwei Wasserfalzrillen ausgebildet sind. Glatte horizontal schuppenförmig angeordnete Dachziegel erreichen entweder durch Mehrfachüberdeckung oder eine tiefliegende ein- oder mehrfache Seitenverfalzung Regensicherheit, die jedoch geringer ist als bei einer muldenförmigen Dacheindeckun.The DE 10 2013 010 169 A1 describes a rebate roof tile with an L-shaped water rebate area and an L-shaped cover rebate area, two water rebate grooves being formed in the water rebate area. Smooth, horizontally, flaky roof tiles achieve rain protection either through multiple coverings or a deep, single or multiple side rebate, which is, however, less than with a trough-shaped roofing.

Die DE 182316 C beschreibt einen anderen Falzdachziegel.The DE 182316 C describes another seam roof tile.

Aufgabe der vorliegenden Erfindung ist es, einen Falzdachziegel zu schaffen der auch bei geringen Dachneigungen die Regensicherheit gewährleistet.The object of the present invention is to create a rebated roof tile which guarantees rainproofing even with low roof slopes.

Erfindungsgemäß wird diese Aufgabe mit dem Gegenstand des Anspruchs 1 gelöst. Bei diesem Gegenstand handelt es sich um einen Falzdachziegel mit einem Kopfabschnitt, einem dem Kopfabschnitt gegenüberliegenden Fußabschnitt und zwei sich gegenüberliegenden Seitenabschnitten.
Der Kopfabschnitt ist an der Unterseite des Falzdachziegels mit einer Aufhängenase zur Halterung an einer Dachlatte ausgebildet ist. Ein L-förmiger Wasserfalzbereich ist an der Oberseite des Falzdachziegels ausgebildet, mit einem Kopf-Wasserfalzbereich im Kopfabschnitt und einem Seiten-Wasserfalzbereich im ersten Seitenabschnitt. Ein L-förmiger Deckfalzbereich ist an der Unterseite des Falzdachziegels ausgebildet, mit einem Fuß-Deckfalzbereich im Fußabschnitt und einem Seiten-Deckfalzbereich im zweiten Seitenabschnitt und zwischen dem Wasserfalzbereich und dem Deckfalzbereich ist ein Mittelfeld ausgebildet. Der Wasserfalzbereich und der Deckfalzbereich sind so ausgebildet, dass im als eine Dacheindeckung verlegten Zustand bei benachbarten Falzdachziegeln der Deckfalzbereich des einen Falzdachziegels den Wasserfalzbereich des anderen Falzdachziegels überlappt. Wesentlich dabei ist, dass der Kopf-Wasserfalzbereich und der Seiten-Wasserfalzbereich mit jeweils vier Wasserfalzstegen und drei Wasserfalzrillen ausgebildet sind, und dass der Fuß-Deckfalzbereich mit drei Deckfalzstegen und zwei Deckfalzrillen ausgebildet ist, und dass der Seiten-Deckfalzbereich mit zwei Deckfalzstegen und einer Deckfalzrille ausgebildet ist.According to the invention, this object is achieved with the subject matter of claim 1. This object is a seam roof tile with a head section, a foot section opposite the head section and two opposite side sections.
The head section is formed on the underside of the seam roof tile with a hanging lug for mounting on a roof batten. An L-shaped water seam area is formed on the top of the seam roof tile, with a head water seam area in the head section and a side water seam area in the first side section. An L-shaped cover rebate area is formed on the underside of the rebate roof tile, with a foot cover rebate area in the foot section and a side cover rebate area in the second side section and a central panel is formed between the water rebate area and the cover rebate area. The water rebate area and the cover rebate area are designed in such a way that, when laid as a roof covering, the cover rebate area of one rebate roof tile overlaps the water rebate area of the other rebate roof tile in the case of adjacent rebated roof tiles. It is essential that the top water fold area and the side water fold area are each formed with four water fold webs and three water fold grooves, and that the foot cover fold area is designed with three cover fold webs and two cover fold grooves, and that the side cover fold area has two cover fold webs and one Cover fold groove is formed.

Durch die drei Wasserrillen im Kopf-Wasserfalzbereich und im Seiten-Wasserfalzbereich und der darin eingreifenden Deckfalzstege kann auch bei geringer Dachneigung ab 7° eine hohe Regensicherheit gewährleistet werden, wobei die Dachneigung durch den Winkel zwischen der Neigung der Dachkonstruktion und der Waagerechten ausgebildet wird. Bei einer geringen Dachneigung zwischen 7° und 10° ist ein bei dem erfindungsgemäßen Falzdachziegel regensicheres oder wasserdichtes Unterdach notwendig. Bei einer geringen Dachneigung ab 10° ist es bei dem erfindungsgemäßen Falzdachziegel nicht notwendig das Unterdach regensicher oder sogar wasserdicht auszubilden. Eine naht- und perforationsgesichtere Unterdeckung oder Unterspannung ist ausreichend, um eine funktionsfähige Zusatzmaßnahme gegen Schlagregen und Schneetrieb zu gewährleisten. Bei steigender Dachneigung über 12° kann das Unterdach durch eine verschweißte oder verklebte Unterdeckung oder eine nahtgesicherte Unterspannung oder eine überlappende oder verfalzte Unterdeckung ersetzt werden. Erfindungsgemäß sind zwei Alternativen a) und b) als und/oder Alternativen vorgesehen.Thanks to the three water grooves in the head water rebate area and in the side water rebate area and the cover rebate webs engaging in them, a high level of rain protection can be guaranteed even with a low roof slope from 7 °, whereby the roof slope is formed by the angle between the slope of the roof structure and the horizontal. If the roof pitch is between 7 ° and 10 °, a rainproof or watertight sub-roof is necessary in the case of the rebated roof tile according to the invention. In the case of the seam roof tile according to the invention, it is not necessary to make the sub-roof rainproof or even watertight if the roof pitch is less than 10 °. A seam and perforation-facing undercover or under-tensioning is sufficient to ensure a functional additional measure against driving rain and snowfall.

Die Figuren 1 und 2 zeigen einen durch Pressen herstellbaren Falzdachziegel 1 mit einem Kopfabschnitt 2 und einem dem Kopfabschnitt 2 gegenüberliegenden Fußabschnitt 3 und zwei sich gegenüberliegenden Seitenabschnitten, den ersten Seitenabschnitt 4 (im Fachbereich als Seitenfalz bekannt) und den zweiten Seitenabschnitt 5 (im Fachbereich als Deckfalz bekannt). Der Falzdachziegel 1 ist so am Dach angeordnet, dass der Kopfabschnitt 2 eines in einer Dacheindeckung angeordneten Falzdachziegels 1 zum Dachfirst weist und der Fußabschnitt 3 zur Dachtraufe weist. An der Unterseite des Falzdachziegels 1 sind im Kopfabschnitt 2 zwei Einhängenasen oder Aufhängenasen 9 zur Halterung des Falzdachziegels 1 an einer Dachlatte ausgebildet.The Figures 1 and 2 show a seam roof tile 1 that can be produced by pressing, with a head section 2 and a foot section 3 opposite the head section 2 and two opposite side sections, the first side section 4 (known in the field as a side fold) and the second side section 5 (known in the field as a cover fold). The rabbet roof tile 1 is arranged on the roof in such a way that the head section 2 of a rabbet roof tile 1 arranged in a roof covering faces the roof ridge and the foot section 3 faces the eaves. On the underside of the rabbet roof tile 1, two hanging lugs or hanging lugs 9 for holding the seam roof tile 1 on a roof batten are formed in the head section 2.

In Figur 1 ist eine perspektivische Ansicht von oben des erfindungsgemäßen Falzdachziegels 1 gezeigt. Auf der Oberseite des Falzdachziegels 1 ist ein Wasserfalzbereich 10 ausgebildet, welcher in Draufsicht des Falzdachziegels 1 L-förmig ausgebildet ist. Der L-förmige Wasserfalzbereich 10 setzt sich zusammen aus einem Kopf-Wasserfalzbereich 12 und einem Seiten-Wasserfalzbereich 14. Der Seiten-Wasserfalzbereich 14 ist im Ausführungsbeispiel in der Figur 1 auf der linken Seite ausgebildet, also im ersten Seitenabschnitt 4. Die Anordnung des Seiten-Wasserfalzbereichs 14 gilt auch im verlegten Zustand mit Blickrichtung von der Dachtraufe in Richtung des Dachfirstes. Im Kopf-Wasserfalzbereich 12 und im Seiten-Wasserfalzbereich 14 sind jeweils drei Wasserrillen 17 ausgebildet, welche durch jeweils vier Wasserfalzstege 16 begrenzt werden. Die Wasserfalzstege 16 sind trapezförmig ausgebildet. Der äußerste Wasserfalzsteg 16 des Seiten-Wasserfalzbereichs 14 weist Sturmklammerkerben 7 auf, die mit einer in den Figuren nicht dargestellten Sturmklammereinrichtung zusammenwirken können.In Figure 1 a perspective view from above of the seam roof tile 1 according to the invention is shown. On the upper side of the seam roof tile 1, a water seam region 10 is formed, which is L-shaped in plan view of the seam roof tile 1. The L-shaped water fold area 10 is composed of a top water fold area 12 and a side water fold area 14. The side water fold area 14 is shown in the exemplary embodiment in FIG Figure 1 formed on the left side, that is, in the first side section 4. The arrangement of the side water fold area 14 also applies in the installed state as viewed from the eaves in the direction of the roof ridge. In the top water fold area 12 and in the side water fold area 14, three water grooves 17 are formed, each of which is delimited by four water fold webs 16. The water fold webs 16 are trapezoidal. The outermost water fold web 16 of the side water fold area 14 has storm clip notches 7 which can interact with a storm clip device not shown in the figures.

In der Figur 1 ist gezeigt, dass die oberste Wasserrille 17 im Kopf-Wasserfalzbereich 12 und die randseitige Wasserrille 17 im Seiten-Wasserfalzbereich 14 miteinander verbunden ausgebildet sind und eine L-förmige Wasserrille 17 über den gesamten Wasserfalzbereich 10 ausbilden. Die mittleren Wasserrillen 17 des Kopf-Wasserfalzbereichs 12 und des Seiten-Wasserfalzbereichs 14 sind auch durchgehend als eine L-förmige Wasserrille 17 ausgebildet.In the Figure 1 it is shown that the uppermost water groove 17 in the head water fold area 12 and the edge water groove 17 in the side water fold area 14 are connected to one another and form an L-shaped water groove 17 over the entire water fold area 10. The central water grooves 17 of the head water fold area 12 and the side water fold area 14 are also continuously formed as an L-shaped water groove 17.

Die äußere Wasserrille 17 und die innere Wasserrille 17 im Seiten-Wasserfalzbereich 14 sind derart ausgebildet, dass die Tiefenerstreckung der Wasserrillen 17 vom Kopfende zum Fußende hin zunimmt (nicht in den Figuren dargestellt). Im untersten Wassersteg 16 im Kopf-Wasserfalzbereich 12, in Fließrichtung gesehen, ist ein Durchbruch 8 zum Mittelfeld 6 hin ausgebildet, damit das Wasser aus der mittleren und der unteren Wasserrille 17 des Kopf-Wasserfalzbereichs 12 über das Mittelfeld 6 hin abfließen kann. Das Wasser der Wasserrillen 17 des Seiten-Wasserfalzbereichs 14 wird über die Wasserrille 17, welche dem Mittelfeld am nächsten liegt, auf den darunter angeordneten Falzdachziegel 1 oder einer Regenrinne abgeleitet.The outer water groove 17 and the inner water groove 17 in the side water fold area 14 are formed in such a way that the depth of the water grooves 17 increases from the head end to the foot end (not shown in the figures). In the lowermost water web 16 in the head water fold area 12, viewed in the direction of flow, an opening 8 is formed towards the middle field 6 so that the water can flow out of the middle and lower water groove 17 of the head water fold area 12 via the middle field 6. The water of the water grooves 17 of the side water fold area 14 is diverted via the water groove 17, which is closest to the central field, onto the folded roof tiles 1 or a rain gutter arranged below.

In Figur 2 ist eine perspektivische Ansicht von unten des erfindungsgemäßen Falzdachziegels 1 gezeigt. Auf der Unterseite des Falzdachziegels 1 ist ein Deckfalzbereich 20 ausgebildet, welcher in Draufsicht des Falzdachziegels 1 L-förmig ausgebildet ist. Der L-förmige Deckfalzbereich 20 setzt sich zusammen aus einem Fuß-Deckfalzbereich 23 und einem Seiten-Deckfalzbereich 25. Der Seiten-Deckfalzbereich 25 ist im Ausführungsbeispiel in der Figur 1 auf der rechten Seite ausgebildet, mit Blickrichtung von der Dachtraufe in Richtung des Dachfirstes, also im zweiten Seitenabschnitt 5, und auf der Unterseite des Falzdachziegels 1 in Figur 2 auf der linken Seite. Im Fuß-Deckfalzbereich 23 sind zwei Deckfalzrillen 27 ausgebildet, welche durch drei trapezförmige Deckfalzstege 26 begrenzt werden. Im Gegensatz dazu ist im Seiten-Deckfalzbereich 25 nur eine Deckfalzrille 27 ausgebildet, welche durch zwei trapezförmige Deckfalzstege 26 begrenzt wird.In Figure 2 is a perspective view from below of the seam roof tile 1 according to the invention is shown. On the underside of the rebate roof tile 1, a cover rebate area 20 is formed, which is L-shaped in plan view of the rebate roof tile 1. The L-shaped cover fold area 20 is composed of a foot cover fold area 23 and a side cover fold area 25. The side cover fold area 25 is shown in the exemplary embodiment in FIG Figure 1 formed on the right side, looking from the eaves in the direction of the roof ridge, i.e. in the second side section 5, and on the underside of the rabbet roof tile 1 in Figure 2 on the left. In the base cover fold area 23, two cover fold grooves 27 are formed, which are delimited by three trapezoidal cover fold webs 26. In contrast to this, only one cover fold groove 27 is formed in the side cover fold area 25, which is delimited by two trapezoidal cover fold webs 26.

Der Wasserfalzbereich 10 und der Deckfalzbereich 20 sind so ausgebildet, dass im als Dacheindeckung verlegten Zustand bei benachbarten Falzdachziegeln 1 der Seiten-Deckfalzbereich 25 des einen Falzdachziegels 1 den Seiten-Wasserfalzbereich 14 des anderen Falzdachziegels 1 überlappt. Dadurch greifen Deckfalzstege 26 in Wasserfalzrillen 17 ein und Wasserfalzstege 16 in Deckfalzrillen 27. Der Kopf-Wasserfalzbereich 12 wird im als Dacheindeckung verlegten Zustand vom Fuß-Deckfalzbereich 23 des darüber liegenden Falzdachziegels 1 vollständig überdeckt. Der Seiten-Wasserfalzbereich 14 wird im als Dacheindeckung verlegten Zustand vom Seiten-Deckfalzbereich 25 des seitlich darüber liegenden Falzdachziegels 1 vollständig überdeckt.The water rebate area 10 and the cover rebate area 20 are designed in such a way that, when laid as a roof covering, they are adjacent Falzdachziegeln 1 the side seam area 25 of one seam roof tile 1 overlaps the side water seam area 14 of the other seam roof tile 1. As a result, cover rebate webs 26 engage in water rebate grooves 17 and water rebate webs 16 in cover rebate grooves 27. The top water rebate area 12 is completely covered by the foot cover rebate area 23 of the rebated roof tile 1 above when laid as a roof covering. In the state laid as a roof covering, the side water rebate area 14 is completely covered by the side rebate area 25 of the rebated roof tile 1 lying laterally above it.

Der als Dacheindeckung verlegte Zustand ist in den Figuren 3 und 4 gezeigt. Figur 3 zeigt einen Längsschnitt zweier sich überlappender Falzdachziegel 1, also einen Schnitt von Dachfirst zu Dachtraufe. Figur 4 zeigt einen Querschnitt zweier sich überlappender Falzdachziegel 1.The condition laid as a roof covering is in the Figures 3 and 4th shown. Figure 3 shows a longitudinal section of two overlapping folded roof tiles 1, that is to say a section from roof ridge to eaves. Figure 4 shows a cross section of two overlapping seam roof tiles 1.

Wie in Figur 3 gezeigt, ist im verlegten Zustand der Falzdachziegel 1 der Fuß-Deckfalzbereich 23 über dem Kopf-Wasserfalzbereich 12 angeordnet, und greift mit seinen Deckfalzstegen 26 in die Wasserfalzrillen 17 ein. Der unterste Deckfalzsteg 26, in Fließrichtung gesehen, liegt auf dem untersten Wasserfalzsteg 16 des Kopf-Wasserfalzbereichs 12 auf, so dass der unterste Deckfalzsteg 26 nicht in eine Wasserfalzrille 17 des darunter liegend angeordneten Falzdachziegels 1 eingreift. Die Fließrichtung in der Figur 3 ist von rechts nach links, d.h. rechts ist firstseitig und links ist traufseitig. Eine Wasserfalzrille 17, in welche kein Deckfalzsteg 26 eingreift, bildet eine sogenannte Wirbelkammer 30.
Figur 4 zeigt einen Querschnitt durch zwei Falzdachziegel 1 im verlegten Zustand. Der Seiten-Deckfalzbereich 25 überlappt dabei den Seiten-Wasserfalzbereich 14 des darunterliegend angeordneten Falzdachziegels 1.As in Figure 3 As shown, in the installed state of the seam roof tile 1, the foot cover rebate area 23 is arranged above the head water rebate area 12 and engages with its cover rebate webs 26 in the water rebate grooves 17. The lowermost cover rebate web 26, seen in the direction of flow, rests on the lowermost water rebate web 16 of the top water rebate area 12, so that the lowermost cover rebate web 26 does not engage in a water rebate groove 17 of the rebate roof tile 1 arranged below. The direction of flow in the Figure 3 is from right to left, ie right is on the ridge side and left is on the eaves side. A water fold groove 17, in which no cover fold web 26 engages, forms a so-called vortex chamber 30.
Figure 4 shows a cross section through two folded roof tiles 1 in the installed state. The side cover rebate area 25 overlaps the side water rebate area 14 of the rebate roof tile 1 arranged below.

Dabei greifen die Deckfalzstege 26 des Seiten-Deckfalzbereichs 25 in Wasserfalzrillen 17 des Seiten-Wasserfalzbereichs 14 ein. Wie in Figur 4 gezeigt, greifen die die Deckfalzstege 26 in die äußeren Wasserfalzrillen 17 ein. Die mittlere Wasserfalzrille 17 in Figur 4, in welche kein Deckfalzsteg 26 eingreift, bildet eine sogenannte Wirbelkammer 30.The cover fold webs 26 of the side cover fold area 25 engage in water fold grooves 17 of the side water fold area 14. As in Figure 4 As shown, the cover fold webs 26 engage in the outer water fold grooves 17. The center waterfold groove 17 in Figure 4 , in which no cover rebate web 26 engages, forms a so-called vortex chamber 30.
