Description

Die Erfindung betrifft einen Dachfalzziegel, dessen Oberseite durch ein Mittelfeld, ein relatiy zum Mittelfeld höher liegendes Deckfalzfeld, einen seitlich an das Mittelfeld anschließenden Seitenfalzteil und einen oben an das Mittelfeld und an das Deckfalzfeld anschließenden Kopffalzteil gebildet ist.The invention relates to a roof rebate tile, the top of which is formed by a central field, a cover fold field located higher relative to the central field, a side fold part adjoining the middle field laterally and a top fold part adjoining the middle field and the cover fold field.

Bei einem bekannten Dachfalzziegel dieser Art (DE-PS 12 55 276) sind zur Erhöhung der Sicherheit gegen ein Eindringen von Wind, Flugschnee und Treibwasser besondere Maßnahmen getroffen. Diese bestehen u. a. darin, daß im Bereich des Wasserfalzecks ein Sperrkörper angeordnet ist und daß Ausschnitte in den Eckbereichen des Ziegels so ausgebildet sind, daß der Sperrkörper in der Eindeckung von dem den Seitenfalzteil und von dem den Kopffalzteil des Ziegels überdeckenden Nachbarziegel nicht überdeckt wird, hingegen im Bereich des fußseitigen Endes auf der Unterseite des Deckfalzfeldes ein Umfassungskörper vorgesehen ist, der sich durch die in den Ecken der Nachbarziegel gebildete Öffnung erstreckt und den Sperrkörper des darunterliegenden Ziegels umgreift. Es sind auch bereits Dachfalzziegel der gleichen Art bekannt geworden (DE-OS 29 06 472), die einen Sperrkörper mit zugeordnetem Umfassungkörper nicht aufweisen, jedoch andere Maßnahmen im Wasserfalzeck zur Steigerung der Regeneindring-Sicherheit des Dachziegels beinhalten.In a known roofing tile of this type (DE-PS 12 55 276), special measures have been taken to increase the security against the ingress of wind, flying snow and driving water. These exist. a. in that in the area of the Wasserfalzecks a locking body is arranged and that cutouts in the corner areas of the tile are designed so that the covering body is not covered in the covering by the side rebate part and by the head rebate part of the tile, but in the area of a peripheral body is provided on the underside of the cover seam field, which extends through the opening formed in the corners of the neighboring tiles and engages around the blocking body of the underlying brick. Roof rebate tiles of the same type have also become known (DE-OS 29 06 472) which do not have a locking body with an associated surrounding body, but which contain other measures in the water rebate corner to increase the rain penetration security of the roof tile.

Der bekannte Dachziegel hat sich im Sinn der geschilderten Zielsetzung durchaus bewährt. Jedoch hat sich herausgestellt, daß bei relatiy flachen Dächern und in Gegenden, in denen Regen mit hohen Windgeschwindigkeiten verbunden ist, wie das in Monsungebieten der Fall ist, ein Wasserstau im Bereich des vom Seitenfalzteil und dem Deckfalzfeld eingegrenzten Mittelfeldes entstehen kann. Im Zusammenwirken mit einem durch hohe Windgeschwindigkeit verursachten Winddruck kann dieser Wasserstau trotz der oben geschilderten Abdichtmaßnahmen in den vom nächstoberen Dachziegel überdeckten Kopffalzteil hineingetrieben werden, von wo aus das Wasser dann ins Dachinnere eindringen kann.The well-known roof tile has proven itself in the sense of the described objective. However, it has been found that in the case of relatively flat roofs and in areas where rain is associated with high wind speeds, as is the case in monsoon areas, a water build-up can occur in the region of the middle field delimited by the side fold part and the cover fold field. In combination with a wind pressure caused by high wind speeds, this water build-up can be driven into the top rebate part covered by the next roof tile, from where the water can then penetrate into the roof, despite the sealing measures described above.

Aufgabe der Erfindung ist es daher, einen Dachfalzziegel der eingangs angegebenen Art so auszubilden, daß die Sicherheit gegen Regeneintrag auch bei sehr hohen Windgeschwindigkeiten oder sehr flacher Dachneigung gewährleistet ist.The object of the invention is therefore to design a roofing tile of the type specified in such a way that security against rain entry is ensured even at very high wind speeds or very flat roof pitch.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Mittelfeld in den beiden Eckbereichen, die durch den Seitenfalzteil und den Kopffalzteil sowie durch den Kopffalzteil und das Deckfalzfeld gebildet sind, je eine in Richtung auf den Kopffalzteil ansteigende Windleitfläche aufweist.According to the invention, this object is achieved in that the middle field in the two corner regions, which are formed by the side fold part and the top fold part as well as by the top fold part and the cover fold field, each have a wind deflection surface which increases in the direction of the head fold part.

Die Erfindung geht dabei von der Überlegung aus, daß auch eine grössere Wasseransammlung im Bereich des Mittelfeldes keine Gefahr eines Wassereintrages zur Folge hat, wenn es gelingt, auch bei sehr hohen Windgeschwindigkeiten den auf die Wasseransammlung wirkenden Winddruck niedrig zu halten. Dies gelingt erfindungsgemäß dadurch, daß in den beiden genannten Eckbereichen des Mittelfeldes nach oben ansteigende Windleitflächen geschaffen sind, die unmittelbar vor dem Kopffalzteil eine Ablenkung der Luftströmung nach oben bewirken. Überraschenderweise hat sich dabei gezeigt, daß der beabsichtigte Erfolg in zureichendem Ausmaß nur dann erreicht wird, wenn die Windleitflächen auf die Eckbereiche beschränkt sind, d.h. eine quer über das ganze Mittelfeld verlaufende geschlossene Windleitfläche vermieden ist.The invention is based on the consideration that even a larger water accumulation in the area of the middle field does not result in a risk of water entry if it is possible to keep the wind pressure acting on the water accumulation low even at very high wind speeds. This is achieved according to the invention by creating wind deflecting surfaces which rise upwards in the two corner regions of the middle field and which cause a deflection of the air flow upwards directly in front of the top fold part. Surprisingly, it has been shown that the intended success is only achieved to a sufficient extent if the wind deflection surfaces are limited to the corner areas, i.e. a closed wind deflection surface running across the entire middle field is avoided.

Die in den Eckbereichen vorgesehenen Windleitflächen können im Rahmen der Erfindung unterschiedliche Gestalt haben. Von besonderem Vorteil ist es, sie so auszubilden, daß sie sowohl in Richtung zum Kopffalzteil als auch in Querrichtung dazu, d.h. also auf einer Seite zum Seitenfalzteil hin, auf der anderen Seite zum Deckfalzfeld hin, ansteigen. Hierdurch wird die offenbar auftretende seitliche oder diagonale Ablenkung der Luftströmung begünstigt. In der einfachsten Ausführungsform der so gestalteten Windleitflächen sind diese annähernd dreieckig, wobei die den höchsten Punkt bildende Dreieckspitze in der zwischen Seitenfalzteil und Kopffalzteil bzw. zwischen Kopffalzteil und Deckfalzfeld gebildeten Ecke liegt.The wind deflection surfaces provided in the corner areas can have different shapes within the scope of the invention. It is particularly advantageous to design them in such a way that they both in the direction of the top fold part and in the transverse direction thereto, i.e. So rise on one side to the side fold part, on the other side to the cover fold field. This favors the apparently occurring lateral or diagonal deflection of the air flow. In the simplest embodiment of the wind deflecting surfaces designed in this way, they are approximately triangular, the triangle tip forming the highest point being in the corner formed between the side fold part and the top fold part or between the top fold part and the cover fold field.

Es hat sich gezeigt, daß eine Beeinflussung der Luftströmung in dem beabsichtigten Sinn schon durch eine Höhenerstreckung der Windleitflächen nur über einen Teil der Höhe zwischen Mittelfeld und Deckfalzfeld bzw. zwischen Mittelfeld und dem fußfalzseitigen Mittelfeld des in der Eindeckung nächstoberen Ziegels erreicht wird. Jedoch wird eine maximale Regeneindring-Sicherheit dann erreicht, wenn die Windleitfläche im deckfalzseitigen Eckbereich bis zur Höhe des Deckfalzfeldes und die Windleitfläche im seitenfalzseitigen Eckbereich bis auf die Höhe der Oberseite des in der Eindeckung nächstoberen Dachfalzziegels ansteigt. Hierdurch wird nicht nur in den unmittelbaren Eckbereichen ein Übertreten der Wasseransammlung durch die insoweit höhere Schwelle erschwert, sondern vor allem die geschilderte Strömungsleitwirkung so ausgeprägt erzielt, daß auch bei sehr hohen Windgeschwindigkeiten (bis zu 40 m/sec) und bei einer Dachneigung von beispielsweise 15° Regeneindring-Sicherheit gegeben ist.It has been shown that an influence on the air flow in the intended sense is achieved only by extending the height of the wind deflector surfaces only over part of the height between the central field and the top seam field or between the center field and the center field on the foot seam side of the tile next to the roof. However, maximum protection against rain penetration is achieved when the wind deflection surface in the corner area on the rebate side increases to the height of the corner seam area and the wind deflection area in the corner area on the side seam side increases to the height of the top of the roof tile next to the roofing. This not only makes it more difficult for the higher threshold to cross the water accumulation in the immediate corner areas, but above all achieves the flow control effect so pronounced that even at very high wind speeds (up to 40 m / sec) and with a roof pitch of e.g. 15 ° Rain penetration security is given.

Ein Ausführungsbeispiel der Erfindung ist nachfolgend anhand der beiliegenden Zeichnungen näher erläutert. In den Zeichnungen zeigen:

  • Fig. 1 eine Draufsicht auf die Oberseite eines erfindungsgemässen Dachfalzziegels;
  • Fig. 2 eine Stirnansicht des Dachfalzziegels gemäß Fig. 1, gesehen von der Fußseite her (wobei zur deutlicheren Hervorhebung die stirnseitigen Fächen dunkel gehalten sind), und
  • Fig. 3 eine schematische Darstellung mehrerer erfindungsgemässer Dachfalzziegel in der Eindeckung.
An embodiment of the invention is explained below with reference to the accompanying drawings. The drawings show:
  • Figure 1 is a plan view of the top of an interlocking tile according to the invention.
  • Fig. 2 is an end view of the interlocking tile according to FIG. 1, seen from the foot side (with the front faces kept dark for clearer emphasis), and
  • Fig. 3 is a schematic representation of several roofing tiles according to the invention in the covering.

Der. in Fig. 1 dargestellte Dachfalzziegel weist ein Mittelfeld 1, ein Deckfalzfeld 2, einen links an das Mittelfeld 1 anschließenden Seitenfalzteil 3 und einen oben an das Mittelfeld 1 und an das Deckfalzfeld 2 anschließenden Kopffalzteil 4 auf. Wie sich aus Fig. 2 ergibt, liegt das Deckfalzfeld 2 gegenüber dem Mittelfeld 1 beträchtlich höher, beispielsweise um 5 cm, und ist in dem gezeigten Ausführungsbeispiel weitgehend eben. Der Seitenfalzteil 3 sowie der Kopffalzteil 4 sind mit Seitenfalz - bzw. Kopffalzrippen versehen, von denen insbesondere die Kopffalzrippen 41 und 42 verhältnismässig hoch ausgebildet sind und auf gleicher Höhe quer verlaufen. Die Ausgestaltung und Anordnung der Kopf-und Seitenfalzrippen sowie deren Zusammenwirken mit der (nicht gezeigten) Unterseite des Dachfalzziegels im übrigen sind bekannt und bedürfen daher an dieser Stelle keiner näheren Erläuterung.The. Roof rabbet tiles shown in FIG. 1 have a central panel 1, a cover panel 2, a side panel part 3 adjoining the center panel 1 on the left and a top panel portion 4 adjoining the center panel 1 and the top panel panel 2. As can be seen from FIG. 2, the cover fold field 2 lies against Above the center field 1 considerably higher, for example by 5 cm, and is largely flat in the exemplary embodiment shown. The side fold part 3 and the top fold part 4 are provided with side fold or head fold ribs, of which in particular the head fold ribs 41 and 42 are made relatively high and run transversely at the same height. The design and arrangement of the top and side rebate ribs and their interaction with the underside of the roof rebate tile (not shown) are known and therefore do not require any further explanation at this point.

Das Mittelfeld 1 und das Deckfalzfeld 2 erstrecken sich in dem gezeigten Ausführungsbeispiel gleich weit nach oben und grenzen längs einer gedachten, quer zum Dachziegel verlaufenden Linie an den Kopffalzteil 4 an. Sie haben, wie sich aus Fig. 1 ergibt, eine schmale rechteckige Gestalt und nehmen jeweils etwa die Hälfte der in der Eindeckung freiliegenden Ziegeloberseite ein. Erfindungsgemäß sind nun in den beiden Eckbereichen, die das Mittelfeld 1 auf der einen Seite mit dem Seitenfalzteil 3 und dem Kopffalzteil 4 und auf der anderen Seite mit dem Kopffalzteil 4 und dem Deckfalzfeld 2 bildet, Windleitflächen 11, 12 vorgesehen, die unmittelbar ausgehend von der Oberseite des Mittelteils 1 etwa diagonal zu den durch Seitenfalzteil 3 und Kopffalzteil 4 bzw. Kopffalzteil 4 und Deckfalzfeld 2 gebildeten Ecken hin ansteigen. In dem gezeigten Ausführungsbeispiel sind die Windleitflächen 11, 12 weitgehend eben und haben daher die Form von Dreiecken. Die seitenfalzseitige Windleitfläche 11 steigt dabei bis zu einer Höhe an, die der Lage der Oberseite des in der Eindeckung nächstoberen Dachziegels entspricht, wie sich aus Fig. 3 ergibt. Die deckfalzseitige Windleitfläche 12 hingegen ist höher und erreicht mit der Spitze das Niveau des Deckfalzfeldes 2. Unmittelbar oberhalb anschließend an die Windleitflächen 11, 12 weist der Kopffalzteil 4 etwa auf dem Niveau des übrigen Mittelfeldes liegende Abstützflächen 13, 14 auf, auf denen sich in der Eindeckung eine auf der Dachziegelunterseite vorgesehene Fußfalzrippe 15 abstützen kann. Hierdurch schließt der in der Eindeckung jeweils nächstobere Dachziegel eng an die Windleitflächen 11, 12 an, so daß durch diese eine in Längsrichtung des Mittelfeldes 1 verlaufende Luftströmung stufenweise in jeder Dachziegelreihe über das Niveau des nächstoberen Mittelfeldes 1 angehoben wird. Hierdurch wird vermieden, daß im Bereich des Mittelfeldes 1 nach unten laufendes Regenwasser gestaut und über die Kopffalzrippen gedrückt wird.In the exemplary embodiment shown, the center panel 1 and the top seam panel 2 extend equally far upwards and adjoin the top rebate part 4 along an imaginary line running transversely to the roof tile. As can be seen from FIG. 1, they have a narrow rectangular shape and each occupy about half of the top of the brick exposed in the covering. According to the invention, wind deflection surfaces 11, 12 are now provided in the two corner regions, which form the central field 1 on one side with the side fold part 3 and the top fold part 4 and on the other side with the top fold part 4 and the top fold field 2, which start directly from the The top of the middle part 1 rises approximately diagonally to the corners formed by the side fold part 3 and top fold part 4 or head fold part 4 and cover fold field 2. In the exemplary embodiment shown, the wind deflection surfaces 11, 12 are largely flat and therefore have the shape of triangles. The wind deflection surface 11 on the side rebate side rises to a height which corresponds to the position of the upper side of the roof tile next in the covering, as can be seen from FIG. 3. The cover fold-side wind deflector surface 12, on the other hand, is higher and reaches the level of the cover fold field 2 with the tip Covering can support a rebate rib 15 provided on the underside of the roof tiles. As a result, the next roof tile in the covering closely adjoins the wind deflector surfaces 11, 12, so that an air flow running in the longitudinal direction of the central field 1 is gradually raised above the level of the next upper central field 1 in each row of roof tiles. This avoids that rainwater running down in the area of the center field 1 is jammed and pressed over the top fold ribs.

Im Rahmen der Erfindung können Abweichungen von dem gezeigten Ausführungsbeispiel getroffen werden. So brauchen, wie eingangs bereits erwähnt, die Windleitflächen 11, 12 keineswegs auf ihrer Oberseite eben zu verlaufen, sondern können konkav gekehlt sein. Weiterhin können die Abmessungen der Windleitflächen 11, 12, die im gezeigten Ausführungsbeispiel in Längsrichtung des Mittelfeldes 1 etwa 1/6 bis 1/8 der Länge des Mittelfeldes ausmachen, verändert werden.Within the scope of the invention, deviations from the exemplary embodiment shown can be made. Thus, as already mentioned at the beginning, the wind deflection surfaces 11, 12 do not need to run flat on their upper side, but can be grooved concavely. Furthermore, the dimensions of the wind deflection surfaces 11, 12, which in the exemplary embodiment shown make up about 1/6 to 1/8 of the length of the middle field in the longitudinal direction of the middle field 1, can be changed.

Auch ist selbstverständlich die Erfindung nicht auf die geschilderte, etwa hälftige Teilung der in der Eindeckung freiliegenden Dachziegeloberfläche oder auf die annähernd ebene Ausgestaltung des Mittelfeldes und/oder des Deckfalzfeldes beschränkt. Auch kann bei solchen Dachziegeln, die am Dachrand verlegt werden, der Seitenfalzteil 3 ähnlich wie das Deckfalzfeld 2 ausgebildet sein, d.h. auf der Ziegeloberseite keine Falzrippen aufweisen, so daß der Dachfalzziegel insoweit Doppelwulstform hat. In diesem Fall sind zweckmässigerweise die beiden Windleitflächen 11, 12 symmetrisch zueinander ausgebildet, da das die Seitenfalzrippen ersetzende Feld in der Regel auf gleicher Höhe mit dem Deckfalzfeld liegen wird.Of course, the invention is not limited to the above-described, approximately half division of the roof tile surface exposed in the covering or to the approximately flat design of the central field and / or the top fold field. Also, in such roof tiles that are laid on the roof edge, the side rebate part 3 can be designed similarly to the top rebate section 2, i.e. have no folded ribs on the top of the tile, so that the interlocking tile has a double bead shape. In this case, the two wind deflection surfaces 11, 12 are expediently formed symmetrically to one another, since the field which replaces the side fold ribs will generally be at the same height as the cover fold field.
