  • This conventional wall connection construction has several disadvantages: The above-mentioned, true-to-form contact of the rolled lead strip on the top of the wall connection tile is only guaranteed if the interlocking folds of the profiled sheet and the rolled lead strip lie closely against one another. However, this prevents roof ventilation from occurring over the area of the wall connection construction. If roof ventilation is required, additional ventilation measures must therefore be taken. Furthermore, the transitions between different materials of the wall connection construction are always problematic due to the different expansion ratios.

  • this cannot be prevented in climatic conditions in which heavy rain is associated with high wind speeds, such as e.g. is the case in monsoon areas.

  • the roof tile according to the invention has a kink that is largely adapted to the angle formed between the sloping roof and the wall, and moreover is not limited to the upper edge area, but rather lies in such an area of the roof tile that the part that is bent upwards is at least a third of the total length of the roof tile makes up (where the total length is the sum of the length of the lower and the upper, bent part).
  • the upper bent part of the roof tile practically forms a continuation of the wall itself, against which backwater would have to rise vertically in order to be able to step over the upper edge of the roof tile.
  • the proposal according to the invention which includes an articulated brick and a cooperating, only suspended cross-cut brick, also forms the prerequisite for further advantages which are achieved by appropriate configurations.

  • the roof tile used in the context of the wall connection construction according to the invention and the associated cross-cut tile can also, as far as the formation of the folds is concerned, be made using the molds (if the clay roof tile is used) or the casting molds (if the concrete roof tile is used) also serve to manufacture the ridge connection tiles of the same roof tile type.

  • the invention also relates to a roof tile wall connection construction in which, in a corresponding embodiment of the inventive concept described above, the roof tile is not angled transversely to its longitudinal extent, but parallel to its longitudinal extent. This arrangement is important if the wall projecting over the roof connects laterally to the roof tiles.
  • the roof tile is bent about an axis lying approximately in its longitudinal center line in an analogous manner, as described above in connection with a wall adjoining the head side of the roof tiles.
  • the design of the cover in the form of the cross-cut tile remains unchanged even in such a case.

  • the invention is not limited to the use of this special type of roof tile, but any common roof tile, in particular roof rebate tile, can be used for this purpose.
  • the design of the articulated roof tile 6, which deviates from the conventional design, consists in the fact that it extends longitudinally, namely in the region of an edge 7, which runs just above a water outlet groove 9 opening onto the mirror surface 8, at an angle upwards, i.e. is buckled against the direction of arrow II, which corresponds at least approximately to the angle 4 between roof 1 and wall 3.
  • the water outlet groove 9 is in the covered state in the part of the articulated roof tile 6 that runs parallel to the roof plane of the roof 1.

Without this being shown in more detail, the cross-cut tiles 10 lying next to one another overlap one another in the manner known from ridge tiles with a fold not shown.
  • a wooden slat 17 is also fastened in a manner not specified, on the top of which the retaining cam 18 of the roof tile 6 is supported. With its water rebate, the roof tile 6 is in engagement with the top rebate of the next lower roof tile 2 on the roof 1.
  • the inclination of the sloping roof 1 runs in the rafter direction, ie the connection of the wall 3 to the roof 1 is made on the top rabbet side with respect to the roof tiles 2.
  • the wall 3 laterally to the Roof tile 2 should connect, it is necessary, as already explained at the outset, to provide such a roof tile instead of the roof tile 6, which is not bent along a transverse folding line 7, but along the longitudinal center line of the roof tile or a line running parallel to it. Since, as a rule, a wall adjoining the roof forms an angle of 90 ° with the roof, in this case the roof tile is bent accordingly by 90 ° around the line mentioned.
  • the cross-cut tile 10, which in this case can have the same configuration as that according to FIGS. 3 and 4, in this case overlaps the side fold of the roof tile with its folded rib 14.

Description

Die Erfindung betrifft eine Dachziegel-Wandanschlußkonstruktion an einer über ein Schrägdach nach oben sich fortsetzenden Wand, mit den Merkmalen gemäß dem Oberbegriff der Patentanspruche 1 und 6. Eine Dachziegel-Wandanschlußkonstruktion dieser Art ist z.B. aus der DE-C 952 559 bekannt.The invention relates to a roof tile wall connection structure on a wall which continues upwards via a sloping roof, with the features according to the preamble of claims 1 and 6. A roof tile wall connection structure of this type is e.g. known from DE-C 952 559.

Es kommt häufig vor, daß von einer Wand aus ein Dach, insbesondere ein Schrägdach, vorspringt, das mit Dachziegeln einzudecken ist. In diesem Fall muß der Obergang zwischen dem Dach und der Wand besonders gegen eindringende Feuchtigkeit gesichert sein. Zu diesem Zweck ist es bekannt, gesonderte sogenannte Wandanschlußziegel einzusetzen, die in ihrem oberen Randbereich etwas nach oben abgewinkelt sind, um den zwischen der Wand und dem Dach gebildeten Winkel zu überbrücken. Derartige Wandanschlußziegel weisen seiten- und deckfalzseitig zwar eine Verfalzung auf, die mit den entsprechenden Falzen an den seitlich anschließenden Wandanschlußziegeln zusammenwirkt, haben jedoch in dem nach oben abgewinkelten Randbereich eine glatte Fläche. Diese glatte Fläche dient dazu, eine möglichst dichte Anlage einer an der Wand befestigten Blechabdeckung zu ermöglichen. Die Blechabdeckung besteht in der Regel aus einem an der Wand dicht befestigten oder durch eine zusätzliche Blech-Kappleiste abgedichteten Profilblech, das an seinem unteren Rand einen nach innen hakenförmig eingeschlagenen Falz aufweist, und aus einem Walzbleistreifen, der mit einem komplementär umgeschlagenen Randfalz in den Falz des Profilbleches eingehakt ist und an die erwähnte glatte Oberseite des Wandanschlußziegels möglichst dicht anliegend angeformt ist.It often happens that a roof, in particular a pitched roof, projects from a wall and is to be covered with tiles. In this case, the transition between the roof and the wall must be protected against the ingress of moisture. For this purpose, it is known to use separate so-called wall connection tiles, which are angled slightly upward in their upper edge region in order to bridge the angle formed between the wall and the roof. Such wall connection tiles have a rebate on the side and cover seam side, which interacts with the corresponding folds on the laterally adjoining wall connection tiles, but have a smooth surface in the upwardly angled edge region. This smooth surface is used to allow a sheet metal cover attached to the wall to fit as tightly as possible. The sheet metal cover usually consists of a profiled sheet which is tightly fastened to the wall or sealed by an additional sheet metal cap strip, which has a fold folded inwards in the shape of a hook on its lower edge, and a rolled lead strip which is folded into the fold with a complementary folded edge of the profiled sheet is hooked on and is molded onto the smooth top of the wall connection tile as closely as possible.

Diese herkömmliche Wandanschlußkonstruktion hat verschiedene Nachteile: Die erwähnte möglichst formgetreue Anlage des Walzbleistreifens an der Oberseite des Wandanschlußziegels ist nur gewährleistet, wenn die ineinandergreifenden Falze des Profilbleches und des Walzbleistreifens eng aneinander anliegen. Dies verhindert aber, daß über den Bereich des Wandanschlußkonstruktion eine Dachentlüftung erfolgt. Es müssen deshalb, falls eine Dachentlüftung gewünscht ist, zusätzliche Entlüftungsmaßnahmen getroffen werden. Weiterhin sind die Übergänge zwischen unterschiedlichen Materialien der Wandanschlußkonstruktion aufgrund der unterschiedlichen Dehnverhältnisse immer problematisch. So muß das Profilblech, in das der Walzbleistreifen eingehakt ist, normalerweise eine höhere Tragfähigkeit und Festigkeit besitzen und wird deshalb regelmässig aus Eisen- oder Kupferblech gefertigt. Daraus resultieren Bewegungen zwischen Walzbleistreifen und Profilblech bei Temperaturänderungen. Das gleiche gilt für den Übergang zwischen dem Walzbleistreifen und dem in der Regel aus keramischem Material oder Beton bestehenden Wandanschlußziegel. Auch erfordert die Herstellung der Abdeckung an Ort und Stelle in der Regel Blecharbeiten, die für eine sachgemässe Ausführung entweder von Spenglern oder zumindest von einschlägig ausgebildeten Dachdeckern ausgeführt werden müssen, was bei der Dacheindeckung einen zusätzlichen Aufwand bedeutet. Weiterhin ergibt zwar der nach oben abgeknickte Randbereich des Wandanschlußziegels eine im Vergleich zur Neigung des Schrägdaches noch verstärkte Neigung, die das Eindringen von Stauwasser verhindern soll. Dies kann jedoch nicht bei solchen klimatischen Verhältnissen verhindert werden, in denen starker Regen mit grossen Windgeschwindigkeiten verbunden ist, wie das z.B. in Monsungebieten der Fall ist. Vielmehr besteht hier die Gefahr, daß infolge der bewusst glatten Oberseite des Wandanschlußziegels Wasser unter dem Walzbleistreifen hindurch in das Dachinnere eingedrückt wird. Schließlich bildet die Blechabdeckung in dem aus keramischen oder Beton-Dachziegeln bestehenden Dach materialmässig einen Fremdkörper und beeinträchtigt daher das Erscheinungsbild des Daches.This conventional wall connection construction has several disadvantages: The above-mentioned, true-to-form contact of the rolled lead strip on the top of the wall connection tile is only guaranteed if the interlocking folds of the profiled sheet and the rolled lead strip lie closely against one another. However, this prevents roof ventilation from occurring over the area of the wall connection construction. If roof ventilation is required, additional ventilation measures must therefore be taken. Furthermore, the transitions between different materials of the wall connection construction are always problematic due to the different expansion ratios. For example, the profiled sheet in which the rolled lead strip is hooked must normally have a higher load-bearing capacity and strength and is therefore regularly made from sheet iron or copper. This results in movements between the rolled lead strip and the profiled sheet when the temperature changes. The same applies to the transition between the rolled lead strip and the wall connection brick, which is usually made of ceramic material or concrete. Also, the production of the cover on site usually requires sheet metal work, which must be carried out either by plumbers or at least by suitably trained roofers for proper execution, which means additional effort in roofing. Furthermore, the edge area of the wall connection tile which is bent upwards results in an even greater inclination compared to the inclination of the sloping roof, which is intended to prevent the ingress of backwater. However, this cannot be prevented in climatic conditions in which heavy rain is associated with high wind speeds, such as e.g. is the case in monsoon areas. Rather, there is a risk that water will be pressed into the interior of the roof under the rolled lead strip due to the deliberately smooth top of the wall connection tile. Finally, the sheet metal cover forms a foreign body in the roof made of ceramic or concrete roof tiles and therefore impairs the appearance of the roof.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Dachziegel-Wandanschlußkonstruktion der geschilderten Art dahingehend zu verbessern, daß sie auch bei extremem Wasserstau und hohen Windgeschwindigkeiten eine praktisch absolut sichere Abdichtung ergibt, die unabhängig von Temperaturänderungen stets gleich bleibt, und darüber hinaus unter professionell geringerem Aufwand hergestellt werden kann.The invention is therefore based on the object to improve a roof tile wall connection construction of the type described in such a way that it results in a practically absolutely safe seal even with extreme water retention and high wind speeds, which always remains the same regardless of temperature changes, and moreover with less professional effort can be manufactured.

Erfindungsgemäß wird diese Aufgabe gelöst durch die Merkmale gemäß dem Kennzeichen des Patentanspruches 1.According to the invention this object is achieved by the features according to the characterizing part of patent claim 1.

Der erfindungsgemässe Dachziegel weist eine dem zwischen Schrägdach und Wand gebildeten Winkel weitgehend angepasste Abknickung auf, die darüber hinaus sich nicht auf den oberen Randbereich beschränkt, sondern in einem solchen Bereich des Dachziegels liegt, daß der nach oben abgeknickte Teil wenigstens ein Drittel der Gesamtlänge des Dachziegels ausmacht (wobei als Gesamtlänge die Summe der Länge des unteren und des oberen, abgeknickten Teils zu verstehen ist). Hierdurch bildet der obere abgeknickte Teil des Dachziegels praktisch eine Fortsetzung der Wand selbst, an der Stauwasser senkrecht hochsteigen müsste, um über den oberen Rand des Dachziegels hinwegtreten zu können. Infolge des Ersatzes der herkömmlichen Blechabdeckung durch einen aus Keramik oder Beton bestehenden Kappziegel, der lediglich an einer metallischen Aufhängung eingehängt ist, fällt auch der problematische Übergang an der Dichtstelle zwischen der Abdeckung und dem Dachziegel selbst weg. Da die Aufhängung durch den Dachziegel selbst verdeckt werden kann, wird auch das Gesamt-Erscheinungsbild des Daches nicht durch eine metallische Abdeckung beeinträchtigt.The roof tile according to the invention has a kink that is largely adapted to the angle formed between the sloping roof and the wall, and moreover is not limited to the upper edge area, but rather lies in such an area of the roof tile that the part that is bent upwards is at least a third of the total length of the roof tile makes up (where the total length is the sum of the length of the lower and the upper, bent part). As a result, the upper bent part of the roof tile practically forms a continuation of the wall itself, against which backwater would have to rise vertically in order to be able to step over the upper edge of the roof tile. As a result of the replacement of the conventional sheet metal cover by a cut tile made of ceramic or concrete, which is only attached to a metal suspension, the problematic transition at the sealing point between the cover and the roof tile itself is eliminated. Since the suspension can be covered by the roof tile itself, the overall appearance of the roof is not affected by a metallic cover.

Der erfindungsgemässe Vorschlag, der einen Knickziegel und einen damit zusammenwirkenden, lediglich aufgehängten Kappziegel beinhaltet, bildet auch die Voraussetzung für weitere Vorteile, die durch zweckmässige Ausgestaltungen erzielt werden. So ist es von Vorteil, den Dachziegel in seinem oberen Randbereich mit einem Kopffalz zu versehen, in den ein unterer Randfalz an der Innenseite des Kappziegels eingreifen kann. Hierbei erfolgt eine Verfalzung ähnlich derjenigen, die zwischen einem Firstziegel und einem Firstanschlußziegel auftritt. Diese Verfalzung bildet nicht nur einen weiteren erheblichen Widerstand gegen das Eindringen von Stauwasser unter Winddruck, sondern schafft auch die Möglichkeit, durch im Längsverlauf der Kopffalz- und Randfalzrippen vorgesehene Lücken auf einfache Weise eine Dachentlüftung zu bewirken, ohne daß dadurch die Dichtheit gefährdet wird.The proposal according to the invention, which includes an articulated brick and a cooperating, only suspended cross-cut brick, also forms the prerequisite for further advantages which are achieved by appropriate configurations. It is therefore advantageous to provide the roof tile with a top fold in its upper edge area, into which a lower edge fold can engage on the inside of the cross-cut tile. Here is egg Ne rebate similar to that which occurs between a ridge tile and a ridge connection tile. This interlocking not only forms a further considerable resistance to the ingress of backwater under wind pressure, but also creates the possibility of easily venting roof vents through gaps provided in the longitudinal course of the top rebate and edge rebate ribs, without thereby endangering the tightness.

Der im Rahmen der erfindungsgemässen Wandanschlußkonstruktion verwendete Dachziegel und der zugehörige Kappziegel können auch, was die Ausbildung der Falze betrifft, unter Einsatz der Preßformen (bei Ausbildung als Ton-Dachziegel) bzw. der Gießformen (bei Ausbildung als Beton-Dachziegel) hergestellt werden, die auch zur Herstellung der Firstanschluß ziegel des gleichen Dachziegeltyps dienen. Denn der erfindungsgemässe Dachziegel unterscheidet sich von dem üblichen Firstanschlußziegel des gleichen Typs nur dadurch, daß er in seinem Längsverlauf abgeknickt ist. Der erfindungsgemässe Kappziegel entspricht im Prinzip hingegen einem halben Firstziegel, der gewöhnlich mit einem Firstanschlußziegel des entsprechenden Typs zusammen eingedeckt wird. Der Dachziegel und der Kappziegel können daher im einfachsten Fall in den gleichen Formen wie die normalen Firstanschlußziegel bzw. Firstziegel hergestellt und anschließend durch Auseinandertrennen und anschließendes erneutes Verbinden in dem richtigen Winkel bzw. durch blosses Auseinandertrennen gefertigt werden.The roof tile used in the context of the wall connection construction according to the invention and the associated cross-cut tile can also, as far as the formation of the folds is concerned, be made using the molds (if the clay roof tile is used) or the casting molds (if the concrete roof tile is used) also serve to manufacture the ridge connection tiles of the same roof tile type. Because the roof tile according to the invention differs from the usual ridge connection tile of the same type only in that it is bent in its longitudinal course. In contrast, the cross-cut tile according to the invention corresponds in principle to half a ridge tile, which is usually covered together with a ridge connection tile of the corresponding type. In the simplest case, the roof tile and the cross-cut tile can therefore be produced in the same shapes as the normal ridge connection tiles or ridge tiles and then manufactured by separating them and then reconnecting them at the correct angle or simply by separating them.

Die Erfindung bezieht sich weiterhin auch auf eine Dachziegel-Wandanschlußkonstruktion, bei der in entsprechender Ausgestaltung des vorstehend geschilderten Erfindungsgedankens der Dachziegel nicht quer zu seiner Längserstreckung abgewinkelt ist, sondern parallel zu seiner Längserstreckung. Diese Anordnung ist dann von Bedeutung, wenn die über das Dach überstehende Wand seitlich an die Dachziegel anschließt. In diesem Fall ist der Dachziegel um eine etwa in seiner Längsmittellinie liegende Achse in analoger Weise geknickt, wie dies vorstehend in Zusammenhang mit einer an die Kopfseite der Dachziegel anschließenden Wand geschildert ist. Die Ausbildung der Abdeckung in Gestalt des Kappziegels bleibt auch in einem solchen Fall unverändert gleich.The invention also relates to a roof tile wall connection construction in which, in a corresponding embodiment of the inventive concept described above, the roof tile is not angled transversely to its longitudinal extent, but parallel to its longitudinal extent. This arrangement is important if the wall projecting over the roof connects laterally to the roof tiles. In this case, the roof tile is bent about an axis lying approximately in its longitudinal center line in an analogous manner, as described above in connection with a wall adjoining the head side of the roof tiles. The design of the cover in the form of the cross-cut tile remains unchanged even in such a case.

An embodiment of the wall connection construction according to the invention is explained in more detail below with reference to the accompanying drawings. The drawings show:
  • 1 shows a longitudinal section through an inventive roof tile, cut along the line 1-1 in Fig. 2.
  • FIG. 2 shows a plan view of the top of the roof tile according to FIG. 1, seen in the direction of arrow II in FIG. 1;
  • 3 shows a section analogous to FIG. 1 through an inventive roof tile wall connection construction using the roof tile shown in FIGS. 1 and 2, and
  • Fig. 4 is a plan view, seen in the direction of arrow IV in Fig. 3 of the wall connection structure, the side rebate area of the roof tile is shown open.

Die in den Fig. 3 und 4 dargestellte erfindungsgemässe Wandanschlußkonstruktion dient zum Anschluß eines im Ganzen mit 1 bezeichneten Schrägdaches, das mit Ton-Dachziegeln 2 eingedeckt ist, an eine Wand 3, die an das Dach 1 anschließt und sich gegenüber diesem nach oben fortsetzt. Zwischen dem Dach 1 und der Wand 3 ist ein Winkel 4 gebildet, der im gezeigten Ausführungsbeispiel etwa 120° beträgt. Einen Teil der im Ganzen mit 5 bezeichneten Wandanschlußkonstruktion bildet eine Knick-Dachziegel 6, der in den Fig. 1 und 2 für sich allein dargestellt ist. Der Dachziegel 6 entspricht - mit der nachfolgend geschilderten Ausnahme - in Bezug auf die Ausgestaltung seiner Ober- und Unterseite sowie sämtlicher Falze daran einem herkömmlichen Firstanshlußziegel des Types "Karat 70" der Anmelderin. Es versteht sich jedoch, daß die Erfindung nicht auf die Anwendung dieses speziellen Typs eines Dachziegels beschränkt ist, sondern hierfür jeder gebräuchliche Dachziegel, insbesondere Dachfalzziegel, einsetzbar ist.The wall connection construction according to the invention shown in FIGS. 3 and 4 is used to connect a sloping roof, generally designated 1, which is covered with clay roof tiles 2, to a wall 3, which connects to the roof 1 and continues upwards relative to it. An angle 4 is formed between the roof 1 and the wall 3, which is approximately 120 ° in the exemplary embodiment shown. A part of the wall connection construction, designated as a whole by 5, forms an articulated roof tile 6, which is shown on its own in FIGS. 1 and 2. With the exception described below, the roof tile 6 corresponds to a conventional ridge connection tile of the type "Karat 70" of the applicant with regard to the design of its top and bottom sides and all the folds thereon. However, it goes without saying that the invention is not limited to the use of this special type of roof tile, but any common roof tile, in particular roof rebate tile, can be used for this purpose.

Die von der herkömmlichen Gestaltung abweichende Ausbildung des Knick-Dachziegels 6 besteht darin, daß dieser in seinem Längsverlauf, nämlich im Bereich einer Kante 7, welche knapp oberhalb einer auf die Spiegelfläche 8 mündenden Wasseraustrittskehlung 9 verläuft, unter einem Winkel nach oben, d.h. entgegen der Pfeilrichtung II, abgeknickt ist, der zumindest annähernd dem Winkel 4 zwischen Dach 1 und Wand 3 entspricht. Auf diese Weise befindet sich die Wasseraustrittskehlung 9 im eingedeckten Zustand in dem Teil des Knick-Dachziegels 6, der parallel zur Dachebene des Daches 1 verläuft. Dieser Teil macht im gezeigten Ausführungsbeispiel etwa ein Drittel der Gesamtlänge des Dachziegels 6 aus, wobei als Gesamtlänge die Summe der Einzellängen der zueinander im Winkel stehenden Teile des Dachziegels 6 zu verstehen ist.The design of the articulated roof tile 6, which deviates from the conventional design, consists in the fact that it extends longitudinally, namely in the region of an edge 7, which runs just above a water outlet groove 9 opening onto the mirror surface 8, at an angle upwards, i.e. is buckled against the direction of arrow II, which corresponds at least approximately to the angle 4 between roof 1 and wall 3. In this way, the water outlet groove 9 is in the covered state in the part of the articulated roof tile 6 that runs parallel to the roof plane of the roof 1. In the exemplary embodiment shown, this part makes up about a third of the total length of the roof tile 6, the total length being the sum of the individual lengths of the parts of the roof tile 6 which are at an angle to one another.

Die Wandanschlußkonstruktion 5 weist als weiteren Bestandteil einen Kappziegel 10 auf, der im wesentlichen einen L-förmigen Querschnitt hat. Am freien Ende des horizontal liegenden L-Schenkels 11 sind mehrere nach unten abgewinkelte Vorsprünge 12 ausgebildet, während der nach unten gerichtete L-Schenkel 13 eine Falzrippe 14 auf seiner Innenseite aufweist, welche in die Kopfverfalzung des Dachziegels 6 eingreift. Da, wie erwähnt, der Dachziegel 6 bezüglich seiner Verfalzung und damit auch der Kopfverfalzung einem herkömmlichen Firstanschlußziegel entspricht, ist zweckmässigerweise die Falzrippe 14 in Anpassung an diese Kopfverfalzung ausgebildet.The wall connection structure 5 has, as a further component, a cross-cut tile 10 which has an essentially L-shaped cross section. At the free end of the horizontally lying L-leg 11, several downwardly angled projections 12 are formed, while the downward-facing L-leg 13 has a folded rib 14 on its inside, which engages in the interlocking of the roof tile 6. Since, as mentioned, the roof tile 6 corresponds to a conventional ridge connection tile with respect to its interlocking and thus also the top interlocking, the rabbet rib 14 is expediently designed to adapt to this top interlocking.

Die Wandanschlußkonstruktion 5 wird vervollständigt durch eine Winkelprofilschiene 15 aus Metall, die in nicht näher gezeigter Weise an der Wand 3 befestigt ist. Die Winkelprofilschiene 15 hat im wesentlichen U-Querschnitt, dessen einer Schenkel gegenüber dem anderen verlängert ist oder einen L-Querschnitt, an dessen kürzerem L-Schenkel ein hochstehender Rand ausgebildet ist. Die Vorsprünge 12 an dem L-Schenkei 11 des Kappziegels 10 sind hinter den hochstehenden Rand der Winkelprofilschiene 15 eingehängt, so daß sämtliche nebeneinander liegenden Kappziegel 10 von der Winkelprofilschiene 15 getragen werden. Ohne daß dies näher gezeigt ist, übergreifen die nebeneinander liegenden Kappziegel 10 einander in der von Firstziegeln her bekannten Weise mit einer nicht dargestellten Verfalzung.The wall connection structure 5 is completed by an angle rail 15 made of metal, which is attached to the wall 3 in a manner not shown. The angle profile rail 15 has a substantially U cross-section, one leg of which is elongated compared to the other, or an L-cross section, on the shorter L-leg of which a raised edge is formed. The projections 12 on the L-leg 11 of the cut tile 10 are hung behind the upstanding edge of the angle rail 15, so that all the adjacent cut tiles 10 are supported by the angle rail 15. Without this being shown in more detail, the cross-cut tiles 10 lying next to one another overlap one another in the manner known from ridge tiles with a fold not shown.

An der Wand 3 ist weiterhin eine Holzlatte 17 in nicht näher bezeichneter Weise befestigt, auf deren Oberseite sich die Haltenocke 18 des Dachziegels 6 abstützt. Mit seinem Wasserfalz steht der Dachziegel 6 in Eingriff mit dem Kopffalz des nächstunteren Dachziegels 2 auf dem Dach 1.On the wall 3, a wooden slat 17 is also fastened in a manner not specified, on the top of which the retaining cam 18 of the roof tile 6 is supported. With its water rebate, the roof tile 6 is in engagement with the top rebate of the next lower roof tile 2 on the roof 1.

Bei der in den Fig. 3 und 4 gezeigten Wandanschlußkonstruktion verläuft die Neigung des Schrägdaches 1 in Sparrenrichtung, d.h. der Anschluß der Wand 3 an das Dach 1 erfolgt kopffalzseitig in Bezug auf die Dachziegel 2. Für den Fall, daß die Wand 3 seitlich an die Dachziegel 2 anschließen sollte, ist es erforderlich, wie eingangs schon erläutert, anstelle des Dachziegels 6 einen solchen Dachziegel vorzusehen, der nicht längs einer querverlaufenden Knicklinie 7, sondern entlang der Längsmittellinie des Dachziegels oder einer dazu parallel verlaufenden Linie geknickt ist. Da in der Regel eine seitlich an das Dach anschließende Wand mit dem Dach einen Winkel von 90° bildet, ist in diesem Fall der Dachziegel entsprechend um 90° um die genannte Linie geknickt. Der Kappziegel 10, der in diesem Fall die gleiche Ausgestaltung wie derjenige nach den Fig. 3 und 4 haben kann, übergreift in diesem Fall mit seiner Falzrippe 14 den Seitenfalz des Dachziegels.3 and 4, the inclination of the sloping roof 1 runs in the rafter direction, ie the connection of the wall 3 to the roof 1 is made on the top rabbet side with respect to the roof tiles 2. In the event that the wall 3 laterally to the Roof tile 2 should connect, it is necessary, as already explained at the outset, to provide such a roof tile instead of the roof tile 6, which is not bent along a transverse folding line 7, but along the longitudinal center line of the roof tile or a line running parallel to it. Since, as a rule, a wall adjoining the roof forms an angle of 90 ° with the roof, in this case the roof tile is bent accordingly by 90 ° around the line mentioned. The cross-cut tile 10, which in this case can have the same configuration as that according to FIGS. 3 and 4, in this case overlaps the side fold of the roof tile with its folded rib 14.
