Description

Die Erfindung bezieht sich auf einen Dachfalzziegel mit einfacher Seitenverfalzung mit einer äußeren und einer inneren Seitenfalzrippe, Ziegelmittelfeld, wenigstens einem Deckwulst und einfacher Kopfverfalzung mit einer äußeren und einer über Ziegelmittelfeld und Deckwulst durchlaufenden inneren Kopffalzrippe.The invention relates to a roof rebate tile with a simple side rebate with an outer and an inner side rebate rib, brick center panel, at least one cover bead and simple head rebate with an outer and an inner top rebate rib running through the brick center panel and cover bead.

Ein derartiger bekannter Dachfalzziegel ermöglicht weder eine nennenswerte Längsverschiebung noch eine optimale Abdichtung im Bereich der Kopfverfalzung und Seitenverfalzung.Such a well-known roof rebate tile allows neither a significant longitudinal displacement nor an optimal seal in the area of the head rebate and side rebate.

Durch die DE-A-16 59 290 ist ein Dachfalzziegel mit einfacher Seiten- und Kopfverfalzung ohne Längsverschiebemöglichkeit bekannt geworden. Bei diesem Dachfalzziegel ist auch eine horizontale Trennfuge zwischen überdeckender Deckwulstflanke und innerer Seitenfalzrippe vorgesehen, und die beiden Deckfalzrippen und beiden Seitenfalzrippen greifen ineinander ein.From DE-A-16 59 290 a roofing tile with simple side and head interlocking without longitudinal displacement has become known. In this roof rebate tile, a horizontal parting line is also provided between the covering flank flank and the inner side rebate rib, and the two cover rebate ribs and both side rebate ribs engage with one another.

Der Erfindung liegt die Aufgabe zugrunde, einen Dachfalzziegel der eingangs beschriebenen Art zu schaffen, der bei möglichst geringer Längsüberdeckung eine möglichst große Längsverschiebemöglichkeit bei gleichzeitig optimaler Abdichtung auch im Vierziegeleck ergibt.The invention has for its object to provide a roof rebate tile of the type described, which results in the greatest possible longitudinal displacement with the least possible longitudinal overlap with simultaneous optimal sealing in the four-tile corner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,

  • daß eine äußere Fußfalzrippe auf Ziegelmittelfeld und im wesentlichen Deckwulst des überdeckten Ziegels aufliegend und die äußere Kopffalzrippe bis mit geringem Spiel an die Unterfläche des überdeckenden Ziegels herangeführt ausgebildet ist, daß die Höhen der inneren Kopffalzrippe und einer inneren Fußfalzrippe etwa gleich und um ein geringes Spiel kleiner als die halbe Höhe der äußeren Fußfalzrippe sind,
  • und daß in der Kopfverfalzung im Vierziegeleck ein von Rippen umschlossenes, nur zur Kopffalznut und damit zum Ziegelmittelfeld offenes Überschiebeplateau vorgesehen ist.
According to the invention, this object is achieved by
  • that an outer rebate rib resting on the central tile field and essentially the cover bead of the covered brick and the outer head rebate rib is brought up to the bottom surface of the covering brick with little play, that the heights of the inner rebate rib and an inner foot rebate rib are approximately equal and a little less than half the height of the outer foot rib,
  • and that in the top interlocking in the four-tile corner there is a slide-in plateau which is enclosed by ribs and is only open to the top rebate groove and thus to the central tile field.

Ein derartiger Dachfalzziegel weist eine Längsverschiebemöglichkeit auf, die nicht durch die innere Kopffalzrippe und die innere Fußfalzrippe eingeschränkt ist, da sich diese beiden Falzrippen überschieben lassen. Gleichzeitig ist sichergestellt, daß die innere Kopffalzrippe in jeder Verschiebeposition immer in die durch die Oberkanten der äußeren und der inneren Kopffalzrippe verlaufende Ebene eintaucht und damit eine echte Labyrinthdichtung ergibt. Es wird damit eine hohe Dichtigkeit gegen Schlagregen und Treibschnee bei gleichzeitig kleinstmöglicher Überdeckung im Kopfbereich des Ziegels erreicht.Such a roof rebate tile has a longitudinal displacement possibility, which is not restricted by the inner top rebate rib and the inner foot rebate rib, since these two rebate ribs can be pushed over. At the same time, it is ensured that the inner head rebate rib always dips into the plane running through the upper edges of the outer and the inner head rebate rib in every displacement position and thus results in a real labyrinth seal. A high level of tightness against driving rain and drifting snow is achieved with the least possible coverage in the head area of the brick.

Der erfindungsgemäße Dachfalzziegel weist eine Vierfachüberdeckung im Vierziegeleck auf. Durch die erfindungsgemäße Ausbildung des Überschiebeplateaus im Vierziegeleck ist gewährleistet, daß unabhängig von der Verschiebeposition keine Lücke im Vierziegeleck auftritt und somit auch hier eine optimale Abdichtung erreicht ist. Die Entwässerung des Überschiebeplateaus erfolgt auf das Ziegelmittelfeld.The roof rebate tile according to the invention has a fourfold covering in the four-tile corner. The inventive design of the slide-over plateau in the four-tile corner ensures that no gap occurs in the four-tile corner regardless of the shifting position, and thus an optimal seal is also achieved here. The drainage plateau is drained onto the central brick field.

Vorteilhaft ist der Deckwulst im seitlichen Überdeckungsbereich und ein Mittelwulst in der Mitte des Ziegelmittelfeldes vorgesehen.The cover bead is advantageously provided in the lateral overlap area and a center bead in the middle of the central tile field.

Bei einer zweckmäßigen Ausführungsform des erfindungsgemäßen Dachfalzziegels ist zwischen der äußeren und der inneren Kopffalzrippe eine mittlere Kopffalzrippe gleicher Höhe wie die innere Kopffalzrippe und zwischen der äußeren und der inneren Fußfalzrippe eine mittlere Fußfalzrippe gleicher Höhe wie die innere Fußfalzrippe vorgesehen. Hierdurch wird die Abdichtung im Kopffalzbereich des Ziegels zusätzlich verbessert.In an expedient embodiment of the roof rebate tile according to the invention, a middle head rebate rib of the same height as the inner head rebate rib and between the outer and the inner foot rebate rib a middle foot rebate rib of the same height as the inner foot rebate rib are provided between the outer and the inner rebate rib. This additionally improves the sealing in the top rabbet area of the brick.

Vorteilhaft weist die innere Kopffalzrippe wenigstens einen Entwässerungsdurchbruch zum Ziegelmittelfeld hin und die mittlere Kopffalzrippe wenigstens einen, zu dem Entwässerungsdurchbruch der inneren Kopffalzrippe seitlich versetzten Entwässerungsdurchbruch zum Ziegelmittelfeld hin auf. Hiermit wird im Kopffalzbereich eine zusätzliche Labyrinthdichtung in seitlicher Richtung erreicht.The inner head rebate rib advantageously has at least one drainage opening to the central brick area and the central head rebate rib has at least one drainage opening to the brick center section which is laterally offset from the drain opening of the inner head rebate rib. This achieves an additional labyrinth seal in the lateral direction in the top rebate area.

Zweckmäßig ist die Nut zwischen der äußeren und der mittleren Kopffalzrippe durch eine Längsrippe zum Überschiebeplateau hin abgeschlossen. Die Entwässerung des Überschiebeplateaus erfolgt damit auf kürzestem Wege zum Ziegelmittelfeld hin.The groove between the outer and the middle head rebate rib is expediently closed off by a longitudinal rib towards the slide-over plateau. The drainage of the transfer plateau is thus carried out by the shortest route to the central brick area.

Gemäß einer Weiterbildung des erfindungsgemäßen Dachfalzziegels ist die überdeckende Deckwulstflanke derart ausgebildet, daß sie mit der Oberseitenfläche der inneren Seitenfalzrippe des überdeckten Ziegels eine horizontale Trennfuge bildet. Dies ermöglicht eine minimale Querüberdeckung bei gleichzeitiger optimaler Abdichtung im Seitenfalzbereich. Verschmutzung, Vermoosung und Überflutung der Seitenfalznut werden durch die gegenüber dem Ziegelmittelfeld angehobene horizontale Trennfuge vermieden.According to a development of the roof rebate tile according to the invention, the covering flank flank is designed such that it forms a horizontal parting line with the top surface of the inner side rebate rib of the covered tile. This enables a minimal cross coverage with simultaneous optimal sealing in the side rebate area. Contamination, moss and flooding of the side rebate groove are avoided due to the horizontal parting line raised compared to the central tile area.

Vorteilhaft verläuft die innere Seitenfalzrippe geradlinig in voller Höhe bis zum Ziegelfuß und weist am Ziegelfuß einen seitlichen Rippenansatz zur Bildung eines schräg nach außen geneigten Trennfugenteils mit dem überdeckenden Deckwulst auf.The inner side rebate rib advantageously runs in a straight line at full height up to the brick base and has a lateral rib attachment on the brick base to form an obliquely outwardly inclined part of the joint with the overlapping cover bead.

Die äußere Seitenfalzrippe verläuft zweckmäßig geradlinig in voller Höhe bis zu einem um mehr als den maximalen Längsverschiebeweg vom Ziegelfuß entfernten Punkt und endet dort.The outer side rebate rib expediently runs in a straight line at full height to a point which is more than the maximum longitudinal displacement path from the brick base and ends there.

In der Überdeckung greift eine äußere Deckfalzrippe in die von den Seitenfalzrippen gebildete Seitenfalznut ein, während eine innere Deckfalzrippe die äußere Seitenfalzrippe seitlich übergreift. Die Entwässerung der Seitenfalznut erfolgt direkt auf das Überschiebeplateau.In the overlap, an outer cover fold rib engages in the side fold groove formed by the side fold ribs, while an inner cover fold rib engages laterally over the outer side fold rib. The side rebate groove is drained directly onto the slide-over plateau.

Weiter sind vorteilhaft anschließend an den Kopffalzbereich auf dem Ziegelmittelfeld an der inneren Seitenfalzrippe und an dem Deckwulst je eine Verschlußnase mit einer Längserstreckung entsprechend dem maximalen Längsverschiebeweg und in der äußeren Fußfalzrippe entsprechende Aussparungen vorgesehen. Infolge der Aussparungen in der äußeren Fußfalzrippe können bei der Herstellung des Dachfalzziegels Einheitsrähmchen verwendet werden, während die Verschlußnasen dieser Aussparungen in der Eindeckung dichtend und optisch vorteilhaft abdecken.In addition, a locking lug with a longitudinal extension corresponding to the maximum longitudinal displacement path and corresponding recesses are advantageously provided in each case subsequent to the top rebate area on the central brick panel on the inner side rebate rib and on the cover bead. As a result of the recesses in the outer foot rebate rib, standard frames can be used in the production of the roof rebate tile, while the locking lugs of these recesses cover the cover in a sealing and optically advantageous manner.

Gemäß einer Weiterbildung des erfindungsgmä- ßen Dachfalzziegels sind im Fußbereich auf der Ziegelunterseite zwei Längsstegteile vorgesehen, die eine Höhe bis zum Ziegelmittelfeld des überdeckten Ziegels aufweisen und in den Entwässerungsdurchbrüchen der inneren Kopffalzrippe zu liegen kommen. Diese Längsstegteile ergeben eine weitere Abdichtung im Bereich der Entwässerungsdurchbrüche im Kopffalzbereich.According to a further development of the ß Dachfalzziegel tiles are provided in the foot area on the underside of the brick two longitudinal web parts, which have a height up to the central tile field of the covered tile and come to rest in the drainage breakthroughs of the inner head rebate rib. These longitudinal web parts provide a further seal in the area of the drainage openings in the top rebate area.

Zusätzlich können im Kopfbereich auf der Ziegelunterseite gegenüber der wenigstens äußeren Kopffalznut zwei Einhängenasen vorgesehen sein, die eine Höhe bis zum mit dem Ziegelmittelfeld flächenebenengleichen Grund der Kopffalznut des überstapelten Ziegels aufweisen.In addition, two hook-in lugs can be provided in the head area on the underside of the brick opposite the at least outer top rabbet groove, which have a height up to the bottom of the top rabbet groove of the stacked brick which is flush with the central tile area.

Hiermit ergibt sich eine Stapelmöglichkeit des erfindungsgemäßen Dachfalzziegels, die zu einer Höhe der Ziegel in der Stapelung übereinander gleich der Höhe der Ziegel übereinander in der Eindeckung führt. Die Stapelauflage erfolgt ausschließlich auf dem Ziegelmittelfeld bzw. dem mit diesem flächenebenengleichen Grund der Kopffalznut. Die Längsverschiebemöglichkeit des Ziegels wird weder durch die der Stapelung dienenden Längsstegteile noch durch die Einhängenasen behindert. Weiter greifen die Einhängenasen in der Stapelung in die Kopffalznut derart verriegelnd ein, daß die gestapelten Ziegelpakete einwandfrei und abrutschsicher in sich verriegelt sind, so daß ein Ziegelpaket bedenkenlos auf dem Dach abgelegt werden kann, ohne daß einer oder mehrere Ziegel abgleiten können.This results in a possibility of stacking the roof tile according to the invention, which leads to a height of the tiles in the stack on top of one another equal to the height of the tiles one above the other in the covering. The stacking is carried out exclusively on the central tile field or on the same level of the bottom of the top rabbet groove. The possibility of longitudinal movement of the brick is not hindered either by the longitudinal web parts serving for stacking or by the hanging lugs. Furthermore, the hooking lugs in the stack engage in the top rabbet groove in such a way that the stacked brick packs are properly and securely locked, so that a brick pack can be safely placed on the roof without one or more bricks sliding off.

Der in den Fig. 1 und 2 dargestellte Dachfalzziegel weist ein Ziegelmittelfeld 1, eine einfache Seitenverfalzung 2 und eine einfache Kopfverfalzung 3 auf. Unter einfacher Verfalzung ist jeweils eine solche Verfalzung zu verstehen, bei der in eine durch zwei Rippen auf der Ziegeloberseite begrenzte Falznut wenigstens eine Falzrippe auf der Unterseite des Ziegels derart eingreift, daß sie in durch die Oberkanten der Rippen auf der Oberseite des Ziegels verlaufende Ebene eintaucht und damit eine echte Labyrinthdichtung ergibt.The roof rebate tile shown in FIGS. 1 and 2 has a central tile field 1, a simple side rebate 2 and a simple head rebate 3. A simple interlocking is to be understood in such a way that at least one interlocking rib on the underside of the brick engages in a rebate groove delimited by two ribs on the top of the brick in such a way that it dips into the plane running through the top edges of the ribs on the top of the brick and thus results in a real labyrinth seal.

Der in den Fig. 1 und 2 dargestellte Dachfalzziegel weist weiter einen Mittelwulst 4 in der Mitte des Ziegelmittelfeldes 1 sowie einen Deckwulst 5 mit Deckwulstflanke 6 auf. Am Ziegelkopf ist eine äußere Kopffalzrippe 7, eine innere Kopffalzrippe 8 und eine mittlere Kopffalzrippe 9 vorgesehen. Die innere Kopffalzrippe 8 ist durchlaufend über das Ziegelmittelfeld 1, den Mittelwulst 4 und den Deckwulst 5 ausgebildet. In der Kopfverfalzung 3 ist im Vierziegeleck ein Überschiebeplateau 10 vorgesehen, das von Rippen 11 derart umschlossen ist, daß es nur zur Kopffalznut und damit zum Ziegelmittelfeld 1 offen ist. Die Nut zwischen der äußeren Kopffalzrippe 7 und der mittleren Kopffalzrippe 9 ist zum Überschiebeplateau 10 hin durch eine Längsrippe 12 abgeschlossen.The roof rebate tile shown in FIGS. 1 and 2 also has a central bead 4 in the middle of the central tile field 1 and a cover bead 5 with cover bead flank 6. An outer top fold rib 7, an inner top fold rib 8 and a middle head fold rib 9 are provided on the brick head. The inner head rebate rib 8 is formed continuously over the central tile field 1, the central bead 4 and the cover bead 5. In the head rebate 3 in the four-tile corner, a slide-over plateau 10 is provided, which is surrounded by ribs 11 in such a way that it is only open to the top rebate groove and thus to the central tile field 1. The groove between the outer top rabbet rib 7 and the middle top rabbet rib 9 is closed off towards the slide-over plateau 10 by a longitudinal rib 12.

Die innere Kopffalzrippe 8 weist zwei zum Ziegelmittelfeld 1 offene Entwässerungsdurchbrüche 13 und die mittlere Kopffalzrippe 9 zwei Entwässerungsdurchbrüche 14 zum Ziegelmittelfeld 1 auf. Die Entwässerungsdurchbrüche 13 und 14 sind jeweils seitlich zueinander versetzt, so daß in der Kopffalznut eine Labyrinthdichtung in seitlicher Richtung entsteht.The inner head rebate rib 8 has two drainage openings 13 which are open to the brick center section 1 and the middle head rebate rib 9 has two drainage openings 14 to the brick center section 1. The drainage breakthroughs 13 and 14 are laterally offset from one another, so that a labyrinth seal is formed in the lateral direction in the top rabbet groove.

Eine äußere Seitenfalzrippe 15 und eine innere Seitenfalzrippe 16 bilden eine Seitenfalznut 18. Die innere Seitenfalzrippe 16 verläuft geradlinig in voller Höhe bis zum Ziegelfuß und weist am Ziegelfuß einen seitlichen Rippenansatz 17 auf. Der seitliche Rippenansatz 17 ist derart ausgebildet, daß er mit dem überdeckenden Deckwulst 5 in der Dacheindeckung ein schräg nach außen geneigtes Trennfugenteil bildet. Die äußere Seitenfalzrippe 15 verläuft geradlinig in voller Höhe bis zu einem um näher als den maximalen Längsverschiebeweg vom Ziegelfuß entfernten Punkt und endet dort.An outer side rebate rib 15 and an inner side rebate rib 16 form a side rebate groove 18. The inner side rebate rib 16 extends in a straight line at full height up to the brick base and has a lateral rib shoulder 17 on the brick base. The lateral rib shoulder 17 is designed such that it forms an obliquely outwardly inclined parting joint part with the covering covering bead 5 in the roof covering. The outer side rebate rib 15 extends in a straight line at full height to a point that is closer than the maximum longitudinal displacement path from the brick base and ends there.

Anschließend an den Kopffalzbereich sind auf dem Ziegelmittelfeld 1 an der inneren Seitenfalzrippe 16 und an dem Deckwulst 5 je eine Verschlußnase 19 mit einer Längserstreckung entsprechend dem maximalen Längsverschiebeweg vorgesehen.Subsequent to the top rebate area, a locking lug 19 with a longitudinal extension corresponding to the maximum longitudinal displacement path is provided on the inner side rebate rib 16 and on the cover bead 5 on the center brick section 1.

Wie Fig. 2 zeigt, sind auf der Unterseite des Dachfalzziegels eine äußere Fußfalzrippe 21, eine innere Fußfalzrippe 22 und eine mittlere Fußfalzrippe 23 vorgesehen. In der äußeren Fußfalzrippe 21 sind darüber hinaus zwei Aussparungen 20 vorgesehen, in denen die Verschlußnasen 19 in der Überdeckung zu liegen kommen und die Kopffalznut ergänzend abdichten.As FIG. 2 shows, on the underside of the roof tile an outer foot rib 21, an inner foot rib 22 and a middle foot rib 23 are provided. In the outer foot rib 21, two recesses 20 are also provided, in which the locking lugs 19 come to lie in the overlap and additionally seal the top rabbet groove.

Weiter sind auf der Ziegelunterseite eine äußere Deckfalzrippe 24 und eine innere Deckfalzrippe 25 vorgesehen.Furthermore, an outer cover fold rib 24 and an inner cover fold rib 25 are provided on the underside of the brick.

Die äußere Fußfalzrippe 21 ist derart ausgebildet, daß sie in der Überdeckung auf dem Ziegelmittelfeld 1 und im wesentlichen auf dem Mittelwulst 4 und dem Deckwulst 5 des überdeckten Ziegels aufliegt, während die äußere Kopffalzrippe 7 bis mit geringem Spiel an die Unterfläche des überdeckenden Ziegels herangeführt ausgebildet ist. Die Höhen der inneren Kopffalzrippe 8 und der inneren Fußfalzrippe 22 sind etwa gleich und um ein geringes Spiel kleiner als die halbe Höhe der äußeren Fußfalzrippe 21. Die mittlere Kopffalzrippe 9 hat eine Höhe gleich der der inneren Kopffalzrippe 8, und die mittlere Fußfalzrippe 23 hat eine Höhe gleich der der inneren Fußfalzrippe 22. Hierdurch ist eine Längsverschiebebewegung der einander überdeckenden Dachfalzziegel nicht behindert.The outer foot rebate rib 21 is designed such that it rests in the overlap on the central tile field 1 and essentially on the central bead 4 and the cover bead 5 of the covered brick, while the outer head rebate rib 7 is formed up to the undersurface of the covering brick with little play is. The heights of the inner head fold rib 8 and the inner foot fold rib 22 are approximately the same and a little less than half the height of the outer foot fold rib 21. The middle head fold rib 9 has a height equal to that of the inner head fold rib 8, and the middle foot fold rib 23 has one Height equal to that of the inner foot rib 22. This is one Longitudinal movement of the overlapping roofing tiles is not hindered.

Die überdeckende Deckwulstflanke 6 ist derart ausgebildet, daß sie mit der Oberseitenfläche der inneren Seitenfalzrippe 16 des überdeckten Ziegels eine horizontale Trennfuge bildet. Dies ist in Fig. 5 deutlich zu erkennen.The covering flank 6 is formed such that it forms a horizontal parting line with the top surface of the inner side rebate rib 16 of the covered tile. This can be clearly seen in FIG. 5.

Im Fußbereich auf der Ziegelunterseite sind weiter zwei Längsstegteile 26 vorgesehen, die eine Höhe bis zum Ziegelmittelfeld 1 des überdeckten Ziegels aufweisen und in den Entwässerungsdurchbrüchen 13 der inneren Kopffalzrippe 8 zu liegen kommen. Hierdurch ergibt sich eine zusätzliche Labyrinthdichtung im Bereich der Kopffalzrippe 8.In the foot area on the underside of the brick, two longitudinal web parts 26 are further provided, which have a height up to the center brick section 1 of the covered brick and come to rest in the drainage openings 13 of the inner head rebate rib 8. This results in an additional labyrinth seal in the area of the top rabbet rib 8.

Schließlich sind im Kopfbereich auf der Ziegelunterseite gegenüber der äußeren Kopffalznut zwei Einhängenasen 27 vorgesehen, die eine Höhe bis zum mit dem Ziegelmittelfeld 1 flächenebenengleichen Grund der Kopffalznut des überstapelten Ziegels aufweisen. Mit Hilfe nur der Längsstegteile 26 und der Einhängenasen 27 läßt sich eine Stapelung erreichen, in der die Ziegel die gleiche Höhe zueinander aufweisen wie in der Eindeckung. Weiter sind gestapelte Ziegelpakete durch den Eingriff der Einhängenasen 27 in die äußere Kopffalznut einwandfrei und abrutschsicher in sich verriegelt.Finally, two hook-in lugs 27 are provided in the head area on the underside of the brick opposite the outer top rabbet groove, which have a height up to the bottom of the top rabbet groove of the stacked brick which is level with the central tile area 1. With the help of only the longitudinal web parts 26 and the hanging lugs 27, a stack can be achieved in which the bricks are at the same height to one another as in the covering. Furthermore, stacked brick packs are locked in themselves properly and securely by the engagement of the hook-in lugs 27 in the outer top rabbet groove.

In Fig. 3 ist die Kopfverfalzung des in den Fig. 1 und 2 dargestellten Dachfalzziegels schematisch dargestellt. Es ist deutlich zu erkennen, daß innere Kopffalzrippe 8 und mittlere Kopffalzrippe 9 sowie innere Fußfalzrippe 22 und mittlere Fußfalzrippe 23 einander bei einer Längsverschiebung des Dachfalzziegels nicht behindern.In Fig. 3 the head interlocking of the roof tile shown in Figs. 1 and 2 is shown schematically. It can be clearly seen that the inner rebate rib 8 and the middle rebate rib 9 as well as the inner rebate rib 22 and the middle rebate rib 23 do not interfere with one another when the roof rebate tile is displaced longitudinally.

Fig. 4 zeigt eine entsprechende Ausführung der Kopfverfalzung ohne mittlere Kopffalzrippe 9 und mittlere Fußfalzrippe 23.FIG. 4 shows a corresponding design of the head fold without central head fold rib 9 and middle foot fold rib 23.

In Fig. 5 ist die Seitenverfalzung eines Dachfalzziegels nach den Fig. 1 und 2 dargestellt. Die horizontale Trennfuge zwischen der überdeckenden Deckwulstflanke 6 und der Oberseitenfläche der inneren Seitenfalzrippe 16 ist deutlich zu erkennen.5 shows the side interlocking of a roofing tile according to FIGS. 1 and 2. The horizontal parting line between the covering flank 6 and the top surface of the inner side rib 16 can be clearly seen.

In Fig. 5 ist auch zu erkennen, daß die äußere Deckfalzrippe 24 in die von der äußeren Seitenfalzrippe 15 und der inneren Seitenfalzrippe 16 gebildete Seitenfalznut 18 eingreift, während die innere Deckfalzrippe 25 die äußere Seitenfalzrippe 15 seitlich übergreift.In Fig. 5 it can also be seen that the outer cover rib 24 engages in the side fold groove 18 formed by the outer side fold rib 15 and the inner side fold rib 16, while the inner cover fold rib 25 laterally engages over the outer side fold rib 15.

In Fig. 6 sind gestapelte Dachfalzziegel nach Fig. 1 schematisch in Ziegelfußansicht dargestellt. Hier ist zum einen deutlich zu erkennen, daß die Höhe der Ziegel in der Stapelung übereinander gleich der Höhe der Ziegel übereinander in der Eindeckung ist. Weiter läßt sich in Fig. 6 der seitliche Rippenansatz 17 und der von diesem zusammen mit dem überdeckenden Deckwulst 5 gebildete, schräg nach außen geneigte Trennfugenteil deutlich erkennen.In Fig. 6 stacked roofing tiles according to Fig. 1 are shown schematically in a tile base view. On the one hand it can be clearly seen that the height of the bricks in the stack on top of one another is equal to the height of the bricks on top of one another in the covering. 6, the lateral rib attachment 17 and the parting part which is inclined outwards and which is formed by this together with the covering covering bead 5, can be clearly seen.
