Description

Die Erfindung betrifft eine Flachdachpfanne mit einer Kopf-, Seiten-, Deck- und Fußverfalzung, wobei die Kopfverfalzung wenigstens eine zwischen Kopffalzrippen befindliche Kopffalznut aufweist, gemäß dem Oberbegriff des Auspruchs 1.The invention relates to a flat roof tile with a head, Side, top and bottom folds, with the head folds at least a top rabbet groove located between top rabbet ribs has, according to the preamble of expression 1.

Eine derartige Flachdachpfanne ist aus der EP 0 303 993 bekannt. Hier wird die Kopffalznut über den Überlaufkopf, der sich in der inneren Kopffalzrippe befindet, entwässert.Such a flat roof tile is known from EP 0 303 993. Here the top rebate groove is over the overflow head located in the inner head fold rib, drained.

Dieser Überlaufkopf hat zur Folge, daß Regenwasser unter Windeinfluß durch diesen gedrückt wird und über die äußere Kopffalzrippe in den Dachinnenraum gelangt.This overflow head results in rainwater under Wind influence is pushed through this and over the outer Head rebate rib gets into the roof interior.

Aus der EP 0 585 737 ist ein Überlauf ebenfalls im Bereich der äußeren Kopffalzrippe bekannt. Auch hier wird das Regenwasser durch die Öffnung der Wasseraustrittsöffnung in den Dachinnenraum getrieben.From EP 0 585 737 an overflow is also in the range of outer head fold rib known. Here too the rainwater through the opening of the water outlet opening into the roof interior driven.

Eine andere Ausführungsform ist aus der DE 599 798 bekannt. Hier ist die innere Kopffalzrippe geschlossen. Im Kopfseitenfalzeck findet sich allerdings wieder eine, hier auch notwendige, Entwässerungsöffnung, diesmal in der inneren Seitenfalzrippe im Bereich des Kopfseitenfalzecks. Hier wird das Regenwasser ebenfalls durch diese Öffnung über den Rand der äußeren Seitenfalzrippe hinweg in den Dachinnenraum geweht.Another embodiment is known from DE 599 798. Here the inner head fold is closed. In the header fold however, there is another one that is also necessary here Drainage opening, this time in the inner side fold rib in the area of the header side fold. Here is the rainwater also through this opening over the edge of the outer side fold rib blown away into the roof interior.

Bei der DE 1 907 165 ist ein Überlaufkopf ebenfalls im Bereich der äußeren Kopffalzrippe vorhanden. Dieser Ziegel hat nicht nur eine doppelte Kopf-, sondern auch eine doppelte Seitenverfalzung. Er hat jeweils zwei Kopf-, beziehungsweise Seitenfalznuten und drei Kopf-, beziehungsweise Seitenfalzrippen. Hier wird das Wasser bei Windeinfluß ebenfalls durch den Überlaufkopf, der ja eine Öffnung in der inneren Kopffalzrippe darstellt, über das Kopfseiten-, beziehungsweise Kopfdeckfalzeck in den Dachinnenraum eingetrieben.In DE 1 907 165 an overflow head is also in the area the outer head fold rib present. This brick has not only a double head fold, but also a double side fold. It has two top and side rebate grooves and three top or side fold ribs. Here the water is also drained through the overflow head which is an opening in the inner head fold, over the top side or top deck fold into the roof interior driven.

Aus der FR 321 794 ist schließlich ein Dachziegel bekannt, bei dem das zwei Längsmulden enthaltene Ziegelmittelfeld unmittelbar in die Kopffalznut mündet. Diese Nut ist in Richtung auf die Seitenverfalzung geneigt. Der nahtlose Übergang der Kopffalznut bewirkt jedoch eine äußerst mangelhafte Entwässerung des Kopfbereiches, da bei traufseitigem Wind das auf dem Ziegelmittelfeld vorhandene Wasser in den Kopffalzbereich eingetrieben wird. Die seitliche Entwässerung im Bereich der Seitenverfalzung ist gleichfalls mangelhaft, da die Kopffalznut sich nur teilweise in die Seitenfalznut entwässert, der andere Teil rinnt über den seitlichen Ziegelabschluss in das Unterdach.Finally, a roof tile is known from FR 321 794, in which the two longitudinal recesses contained brick center field opens directly into the top rebate. This groove is inclined towards the side fold. The seamless transition of the top groove however, causes an extremely poor drainage of the head area, since at wind on the eaves side the water present in the central tile field in the top rebate area is driven. The lateral drainage in the area of the side folds is also defective, since the top rebate groove only partially drains into the side rebate groove, the other part runs over the side brick edge into the lower roof.

Die Erfindung hat das Ziel, die Wasserüberlaufköpfe, beziehungsweise Wasseraustrittsöffnungen im Bereich des Ziegelkopfes, seien sie in einer Kopffalzrippe oder in einer inneren Seitenfalzrippe, im Bereich des Kopfseitenfalzecks zu vermeiden.The object of the invention is the water overflow heads or water outlet openings in the area of the brick head, be it in a top rabbet rib or in one inner side seam rib, to be avoided in the area of the head side seam corner.

Die Nachteile dieser Wasseraustrittsöffnungen sind seit langer Zeit bekannt. Man hat wiederholt Anstrengungen gemacht, um die Nachteile dieser Wasseraustrittsöffnungen oder Überlaufköpfe auszuschalten. Unter anderem hat man die Wasseraustrittsöffnungen im Bereich der inneren Kopffalzrippe, beziehungsweise der inneren Seitenfalzrippe, im Bereich des Kopfseitenfalzecks einfach geschlossen. Dann bleibt im Bereich der Kopffalznut, beziehungsweise der Nuten Wasser stehen, es bilden sich Wassersäcke. Bei Böen wird das dort stehende Wasser aus der Kopffalznut, durch sich bildende plötzliche Unterdruckgebiete ausgeweht und gelangt in den Dachinnenraum.The disadvantages of these water outlet openings have been known for a long time. One has repeated efforts to address the disadvantages of these water outlets or switch off overflow heads. Among other things, you have the water outlet openings in the area of the inner head fold rib or the inner side fold rib, simply closed in the area of the top seam fold. Then remains in the area of Top rabbet groove, or the grooves of water, water bags form. In the event of gusts, the water standing there becomes from the top groove, due to sudden Vacuum areas blown out and enters the roof interior.

Auch bei den neuesten Entwicklungen hat man nach wie vor nicht auf derartige Wasseraustrittsöffnungen oder Überlaufköpfe verzichten können. Even with the latest developments, there are still no such water outlet openings or can dispense with overflow heads.

Die meisten Dachziegel, insbesondere solche vom Typ Flachdachpfanne, zu denen auch der erfindungsgemäße Ziegel gemäß Oberbegriff zählt, sind sehr oft, wenn sie auf dem Dach liegen, produktionsbedingt, ganz leicht in Richtung Deckfalz geneigt. Damit entsteht der oben bereits angesprochene Wassersack in der Kopffalznut oder den Kopffalznuten, im Bereich des Kopfdeckfalzecks, was besonders schädlich ist, da das dort anstehende Wasser bei Böen sofort in den Dachinnenraum geweht wird.Most roof tiles, especially those of the flat roof tile type, to which the tile according to the preamble according to the invention also counts very often when it is on the roof, due to production, inclined slightly towards the top fold. In order to creates the water bag already mentioned above in the top groove or the Top rabbet grooves, in the area of the top deck fold, which is particularly harmful since that water present there is gust blown into the roof interior immediately.

Die Kopffalznut oder Nuten, wurden bei solchen Dachziegelmodellen stets parallel zu den Auflageflächen der Dachlatten ausgebildet. Durch die leicht geneigte Lage der Ziegel auf der Dachfläche, neigten sich diese Nuten dann im allgemeinen ganz leicht in Richtung Deckfalz. The top rabbet groove or grooves were always parallel to such roof tile models the contact surfaces of the roof battens. Due to the slightly inclined position of the bricks on the roof surface, these grooves then generally inclined very slightly Towards the cover fold.

Aufgabe der Erfindung ist es, die äußere Kopffalznut oder nuten ohne Benützung eines Überlaufkopfes oder einer Wasseraustrittsöffnung zu entwässern.The object of the invention is to groove the outer top groove or without using an overflow head or a water outlet opening to drain.

Erfindungsgemäß wird dies dadurch gelöst, daß der Kopfverfalzung ein Aulagestreifen vorgelagert ist, der die Verbindung zum Mittelfeldschafft, und daß die Kopffalznut in Richtung auf die Seitenverfalzung geneigt ist, so daß sich vom deckfalzseitigen Ende der Kopffalznut in Richtung auf den Seitenfalz ein Gefälle ergibt, das eine schnellere Entwässerung der Kopffalznut, beziehungsweise Kopffalznuten sicherstellt und eine eventuell leicht, produktionsbedingte Schräglage der Kopffalznut oder Nuten überwunden werden.According to the invention, this is achieved in that the head fold is preceded by an assembly strip which creates the connection to the middle field, and in that the head fold groove is inclined towards the side fold, so that from the top seam-side end of the top groove in the direction of the Side fold gives a slope that allows faster drainage the top rebate groove or top rebate grooves ensures and a possibly slight, production-related inclined position of the top groove or grooves are overcome.

Mit dieser schnellen Entwässerung wird auch erreicht, daß das bei der Eindeckung stets kritische Vierziegeltreffeck weniger anfällig ist, weil durch die Neigung der Kopffalznut oder Nuten das Wasser von den im deckfalzseitigen Ende der Kopffalznut vorhandenen Ausschnitten weggefördert wird.With this rapid drainage it is also achieved that Critical four-tile target less when covering is susceptible because of the inclination of the top rabbet groove or grooves the water from the in the top seam-side end of the top groove existing cutouts is promoted.

Bei der Entwässerung der Kopffalznut sollte die Neigung so bestimmt werden, daß nicht nur die Adhäsionskräfte des Tonscherben überwunden werden, sondern daß sich auch ein fühlbarer schneller Abfluß der Nut ergibt. Die effektive Neigung gegenüber der Dachlatte sollte mindestens 0,5° betragen, sie wird wohl vornehmlich bei 1°, 2° oder mehr liegen.The slope should be determined in this way when draining the top rebate groove that not only the adhesive forces of the pottery shards be overcome, but that is also a palpable rapid drainage of the groove results. The effective inclination towards the roof batten should be at least 0.5 °, it will probably primarily at 1 °, 2 ° or more.

Eine vorteilhafte Weiterbildung besteht darin, daß der inneren Kopffalzrippe und/oder der inneren Seitenfalzrippe in Richtung auf das Ziegelmittelfeld ein Auflagestreifen vorgeordnet ist, der beim Eindecken den Verschiebebereich des Ziegels abdeckt.An advantageous development is that the inner Head fold rib and / or the inner side fold rib in the direction a support strip is placed in front of the central tile field, which covers the sliding area of the tile when covering.

Der Kopffalzauflagestreifen ist eben und verläuft parallel zur Dachlatte. Im Gegensatz zur Kopffalznut ist er nicht geneigt. Er liegt auch in einer Ebene mit dem eventuell vorhandenen Seitengfalzauflagestreifen. Beide bilden bei der Eindeckung die Auflage für das Fußfalzteil, beziehungsweise das Deckfalzteil der überdeckenden Nachbarziegel. Hieraus ergeben sich eine horizontale Kopf- beziehungsweise Seitentrennfuge. The top rabbet support strip is flat and runs parallel to Batten. In contrast to the top groove, it is not inclined. It is also on one level with the side gusset strip that may be present. Both form the covering Support for the foot rebate part or the top rebate part the covering neighboring tile. This results in a horizontal one Head or side parting line.

Eine vorteilhafte Weiterbildung besteht darin, daß die Seitenfalznut oder Nuten, insbesonderre jene Seitenfalznut, in die die Kopffalznut einmündet, nur mäßig ansteigend in einem Winkel kleiner als 6° ausgebildet werden. Ein Anstieg der Seitenfalznut, beziehungsweise Seitenfalznuten ist notwendig, um im Bereich der Wasseraustrittsöffnung im Fußseitenfalzeck, einen Höhenunterschied zu erreichen. Hierdurch ergibt sich im Fußseitenfalzeck eine Stufe, die ihrerseits das Einwehen von Wasser in die Seitenfalznut verhindert.An advantageous development is that the side groove or grooves, in particular that side groove in which the top rabbet groove opens out, only moderately rising at an angle be formed smaller than 6 °. An increase in the side groove, or side rebate grooves is necessary to in the area the water outlet opening in the toe fold, a difference in height to reach. This results in the fold at the foot side a stage that in turn is blowing in water prevented in the side groove.

An embodiment is described below with reference to a drawing. Show it:
Figure 1
a plan view of a flat roof tile according to the invention,
Figure 2
a section through the pan of Figure 1 along line II-II.

Der Dachziegel 1 verfügt über einen Kopffalzteil 2, einen Deckfalzteil 3, einen Fußfalzteil 4, einen Seitenfalzteil 5, sowie über ein Mittelfeld 6. Zwischen Kopffalzteil und Seitenfalzteil ergibt sich ein Kopfseitenfalzeck 28, während zwischen dem Kopffalzteil und dem Deckfalzteil ein Kopfdeckfalzeck 29 vorhanden ist, das im Bereich der Kopfverfalzung zwei Eckausschnitte aufweist.The roof tile 1 has a top rebate part 2, a top rebate part 3, a foot fold part 4, a side fold part 5, and over a middle field 6. Between top fold part and side fold part there is a top-side fold corner 28, while between the Head fold part and the top fold part a top cover fold corner 29 present is that in the area of the head rebate two corner cutouts having.

Das Kopffalzteil 2 besitzt eine äußere Kopffalzrippe 213, die über eine Kopffalznut 214 von einer inneren Kopffalzrippe 215 getrennt ist. Letzterer ist ein Auflagestreifen 6133 vorgelagert, der in etwa so breit ist wie die Kopffalznut 214 und die Verbindung schafft zum Ziegelmittelfeld 6.The head rebate part 2 has an outer head rebate rib 213 which via an inner rabbet groove 214 from an inner rabbet rib 215 is separated. The latter is preceded by a support strip 6133, which is approximately as wide as the top groove 214 and the Connects to the central brick field 6.

Der Seitenfalzteil 5 zeigt eine äußere Seitenfalzrippe 513, eine Seitenfalznut 514, eine innere Seitenfalzrippe 515, die in dieser Reihenfolge einander nachgelagert zwischen dem äußeren Ziegelrand und dem Ziegelmittelfeld 6 vorhanden sind. Die Kopffalznut 214 geht stufenlos in die Seitenfalznut 514 über. The side fold part 5 shows an outer side fold rib 513, one Side fold groove 514, an inner side fold rib 515, which in this order is placed one after the other between the outer Brick edge and the brick center 6 are available. The top rabbet groove 214 merges smoothly into the side groove 514.

Der Anstieg der Seitenfalznut 514 beginnt unmittelbar in Nähe der Einmündung vo Kopffalzrippe 215 in die innere Seitenfalzrippe 515 und setzt sich mit einem Anstieg kleiner als 6° bis zur Wasseraustrittsöffnung im Bereich Fußseitenfalzecks fort.The increase in the side groove 514 begins immediately in the vicinity the confluence of the top fold rib 215 and the inner side fold rib 515 and continues with an increase of less than 6 ° to to the water outlet opening in the area of the side seam fold.

Beide Auflagestreifen - soweit vorhanden - bilden bei Eindekkung ein Auflager für die Fußverfalzung, beziehungsweise Deckverfalzung der überdeckenden Nachbarziegel. Sie bedingen bei der Eindeckung eine horizontale Kopf- und Seitentrennfuge.Both contact strips - if available - form when covered a support for the foot rebate or top rebate the covering neighboring tile. They condition a horizontal head and side joint.

Die Kopffalznut 214 ist gegenüber der Dachlattenauflage, das heißt gegenüber der Ebene der Dachlatten in einem Winkel α in Fallrichtung auf die Seitenverfalzung 5 geneigt. Die Kopffalznut beginnt am einen Eckausschnitt des Kopfdeckfalzecks 29 und mündet somit leicht fallend in die Seitenfalznut 514 und zwar im Bereich des Kopfseitenfalzecks 28. Bedingt durch die Neigung und durch den stufenlosen Übergang der beiden Nuten wird die Kopffalznut auch bei erhöhtem Wassereintrag, zum Beispiel bei traufseitigem Wind, rasch entwässert. Dies vermindert die Gefahr, daß das in der Nut aufgenommene Wasser über die äußere Kopffalzrippe 213 hinweg in die Dachunterseite eingeweht wird.The top rebate groove 214 is opposite the roof battens, that means in relation to the plane of the roof battens at an angle α in Fall direction inclined to the side folds 5. The top rabbet groove begins at a corner section of the top deck corner 29 and thus opens into the side groove 514 in a slightly falling manner in the area of the top side seam corner 28. Due to the inclination and through the stepless transition of the two grooves, the Top rebate groove even with increased water input, for example with eaves-side wind, quickly drained. This reduces the risk that the water absorbed in the groove through the outer Head fold rib 213 is blown into the underside of the roof.

Der Neigungswinkel α ist so groß zu bestimmen, daß sich auch bei beruhigter Luft das in der Kopffalznut gesammelte Wasser durch die Schwerkraft in Richtung auf den Seitenfalzteil bewegt. Hierzu muß die Adhäsionskraft überwunden werden.The angle of inclination α is to be determined so large that also in calm air, the water collected in the top groove moved by gravity towards the side fold part. To do this, the adhesive force must be overcome.

Dies bedingt aus physikalischen Gründen wenigstens eine Neigung von zirka 0,5°, wobei eine Neigung von ungefähr 1° bereits einen sichtbaren Abfluß in Richtung auf das Seitenfalzteil ermöglicht.For physical reasons, this requires at least one inclination of approximately 0.5 °, with an inclination of approximately 1 ° already one allows visible drainage towards the side rebate.

Die mit der Erfindung sich ergebende gute Entwässerung der Kopffalznut macht einen Wasserauslaß der inneren Kopffalzrippe 215 überflüssig.The good drainage resulting from the invention Top fold groove makes water outlet of the inner top fold rib 215 superfluous.

Um eine einwandfreie Auflage des Dachziegels auf den Dachlatten und damit die schräge Neigung der Kopffalznut, beziehungsweise Nuten zu gewährleisten, ist im Bereich der Aufhängenase im Bereich des Deckfalzteiles 3 an der Ziegelrückseite eine Auflageleiste 226 angeordnet. Sollte im Bereich des Seitenfalzteiles an der Ziegelrückseite eine Rippe, zum Beispiel zur Abführung von Wasser vorgesehen sein, dann ist auch im Bereich des Kopfseitenfalzecks eine Auflageleiste vorgesehen, damit die Wasserableitrippe nicht auf der Dachlatte aufliegt. In diesem Fall muß die im Bereich des Kopfdeckfalzecks vorgesehene Auflageleiste 226 um den Betrag tangens α mal dem Abstand der beiden Auflageleisten höher ausgebildet werden.To ensure that the tile fits perfectly on the roof battens and thus the oblique inclination of the top rabbet groove, respectively Ensuring grooves is in the area of the hanging nose in the area of the top seam part 3 on the back of the brick a support bar 226 arranged. Should be in the area of the side rebate a rib on the back of the brick, for example for removal be provided by water, then is also in the area of the top side fold a support bar is provided so that the water drainage rib does not rest on the roof batten. In this case the support strip provided in the area of the top deck corner 226 by the amount tangent α times the distance between the two Support strips are trained higher.
