Abstract

The line of tiles (31) adjoining the rainwater gutter (26) of a sloping roof are formed with the lower half (31b) of the tile bent downwards at an angle which is steeper than the roof angle. The line of the bend is parallel to the upper and lower edges of the tile. This increased slope of the lower half of the tile directs rainwater, which runs off the roof, into the gutter. This reduces the risk of the rainwater being directed over the edge of the gutter during very heavy rainfall.

Description

Die Traufe eines Daches wird in der Regel so ausgebildet, daß im Bereich der unteren Dachziegelreihe auf den Sparren eine Bretterschalung mit einer Traufbohle oder eine Bretter- oder Lattenschalung mit einem Keilstück vorge­sehen wird, wobei die unteren Dachziegel auf der Trauf­bohle bzw. auf der von dem Keilstück abgestützten Schalung aufliegen. Die keilförmig zugeschnittene Traufbohle bzw. das Keilstück müssen so hoch sein, daß die untere Dach­ziegelreihe im wesentlichen dieselbe Neigung wie die oberen Dachziegelreihen erhält. Die untere Dachziegel­reihe wird gewöhnlich durch gesondert geformte Trauf­ziegel gebildet, die sich von den Flächenziegeln nur dadurch unterscheiden, daß der Querabschluß am unteren Rand des Ziegelfusses durch einen besonders hohen Falz gebildet ist, welcher zugleich eine Sichtblende bildet und verhindert, daß Vögel oder anderes Kleingetier zu leicht unter die Dachfläche gelangen können. Zur Aufnahme des über die unterste Dachziegelreihe ablaufenden Dach­flächenwassers ist an den Sparrenenden eine Dach- oder Traufrinne angeordnet, deren Halter an den Sparren oder an der Traufbohle befestigt sind und die in einer sog. hängenden Ausbildung zugleich als teilweise oder voll­ständige Sichtblende für die Sparrenstirnseiten dient. Die Traufziegel dürfen nur möglichst wenig über die Dach­rinne vorragen, da sonst vor allem in Gegenden, in welchen Starkregen auftreten, das in grosser Menge anfallende und mit erheblicher Geschwindigkeit über die unterste Dachziegelreihe laufende Dachflächenwasser zu einem beträchtlichen Teil über den Dachrinnenrand hinaus­schießt, so daß die Dachrinne weitgehend wirkungslos ist. Da andererseits aber die Traufkonstruktion, nämlich die Traufbohle, die Schalung und ggf. darunter befindliches Mauerwerk vor dem Einwehen von Spritzwasser und Schnee sorgfältig geschützt werden müssen, ist trotz des er­wähnten Fußfalzes von Traufziegeln regelmässig die An­bringung eines Traufbleches erforderlich, das den Sparren­fuß bei hängender Dachrinne schützt.The eaves of a roof is usually designed so that in the area of the lower row of roof tiles on the rafters a board formwork with an eaves board or a board or slat formwork with a wedge piece is provided, the lower roof tiles on the eaves board or on the Support the wedge-supported formwork. The wedge-shaped eaves or the wedge piece must be high enough that the lower row of roof tiles receives essentially the same inclination as the upper rows of roof tiles. The lower row of roof tiles is usually formed by specially shaped eaves tiles, which differ from the flat tiles only in that the transverse termination at the lower edge of the tile base is formed by a particularly high fold, which also forms a screen and prevents birds or other small animals from closing can easily get under the roof surface. A roof or eaves gutter is arranged on the rafter ends to hold the water flowing over the lowest row of roof tiles, the holder of which is fastened to the rafters or the eaves plank and, in a so-called hanging design, also serves as a partial or complete screen for the rafters' front sides. The eaves tiles should protrude as little as possible over the gutter, because otherwise, especially in areas where heavy rain occurs, in large quantities accumulating and running at considerable speed over the lowest row of roof tiles roof water to a considerable extent over the gutter edge, so that the gutter is largely ineffective. On the other hand, since the eaves construction, namely the eaves plank, the formwork and any masonry located underneath, must be carefully protected from the ingress of splashing water and snow, despite the mentioned rebate of eaves bricks, it is regularly necessary to attach an eaves plate that supports the rafter foot when the gutter is hanging protects.

Der Erfindung liegt die Aufgabe zugrunde, einen Trauf-­Dachfalzziegel zu schaffen, der ohne eine Beeinträchtigung der Regen- und Schneesicherheit eine Vereinfachung der geschilderten Traufkonstruktion ermöglicht, nämlich einen Verzicht auf das Traufblech erlaubt.The invention has for its object to provide an eaves roof rebate tile that allows simplification of the described eaves construction without impairing the rain and snow safety, namely allows the eaves sheet to be dispensed with.

Erreicht wird dies erfindungsgemäß durch einen Trauf-­Dachfalzziegel, der in seinem Längsverlauf um eine zu seinem unteren Rand zumindest annähernd parallele Linie nach unten abgewinkelt ist.This is achieved according to the invention by an eaves roofing tile, which is angled down in its longitudinal course around a line at least approximately parallel to its lower edge.

Von den herkömmlichen Traufziegeln, die in ihrem Längs­verlauf, d.h. von ihrem oberen firstseitigen zu ihrem unteren traufseitigen Rand hin, weitgehend geradlinig oder nur - im Bereich ihres unteren Randes - geringfügig nach unten gewölbt ausgebildet sind, unterscheidet sich der erfindungsgemässe Traufziegel durch eine kräftige Abknickung oder Abwinkelung, die schon ab der Längs­mitte des Dachziegels einsetzen kann. Damit ist der erfindungsgemässe Traufziegel in einen oberen Flächen­teil und einen unteren Flächenteil unterteilt, wobei der obere Flächenteil etwa gleich wie die darüber an­schließenden Flächenziegel geneigt ist, während dem­ gegenüber der untere Flächenteil stärker nach unten geneigt ist und deshalb darüberfließendes Wasser betont auf den Boden der anschließenden Dachrinne lenkt. Je grösser die Ausdehnung des unteren Flächenteiles ist, umso ausge­prägter ist die "Lenkfunktion" des Traufziegels, weshalb die Knicklinie bevorzugt in einem Bereich zwischen der Längsmitte und der unteren Längsdrittellinie des Trauf­ziegels angeordnet ist. Bei einer Abwinkelung unter einem Winkel von 20 bis 45° wird bei unveränderter Anordnung der Dachrinne Sicherheit gegenüber den Rand überschießendes Wasser gewährleistet. Der erfindungsgemässe Trauf­ziegel erübrigt somit häufig notwendige Anpaßmaßnahmen bei der Anbringung der Dachrinne.The eaves tile according to the invention differs from the conventional eaves tiles, which are largely straight in their longitudinal course, i.e. from their upper ridge-side to their lower eaves-side edge, or only slightly curved downwards in the area of their lower edge, by a strong kink or Angling that can start from the longitudinal center of the roof tile. The eaves tile according to the invention is thus subdivided into an upper surface part and a lower surface part, the upper surface part being inclined approximately the same as the surface tiles adjoining it during the Compared to the lower part of the surface is more inclined downwards and therefore water flowing over it directs the bottom of the subsequent gutter. The greater the extent of the lower surface part, the more pronounced is the "steering function" of the eaves tile, which is why the crease line is preferably arranged in a region between the longitudinal center and the lower longitudinal third line of the eaves tile. With an angle of 20 to 45 ° with an unchanged arrangement of the gutter, security against water overflowing the edge is guaranteed. The eaves tile according to the invention thus often eliminates the need for adaptation measures when attaching the gutter.

Infolge der Abwinkelung des erfindungsgemässen Traufziegels bildet dessen Oberseite die erwünschte Sichtblende und den Schutz gegen ein Eindringen von Kleingetier unter die Dachfläche. Aus diesem Grund ist der herkömmlicherweise am unteren Rand vorgesehene Fußfalz nicht erforderlich. Jedoch hindert nichts, z.B. aus Gründen der höheren Festigkeit oder zur Auflagerung auf den Trockenrähmchen bei der Herstellung als Preß-Dach­ziegel, diesen Fußfalz weiterhin vorzusehen. Es versteht sich im übrigen, daß der erfindungsgemässe Traufziegel auch in seinem unteren abgewinkelten Flächenteil die mit den nächstanschließenden Traufziegeln zusammen­wirkenden Verfalzungen im Seiten- und Deckfalzbereich aufweist und im übrigen die gleiche Ausgestaltung für den Ortgang wie bisher ermöglicht. Der erfindungsgemässe Traufziegel kann sowohl im Preßverfahren als Ton-Dach­ziegel als auch als Beton-Dachziegel hergestellt werden.As a result of the angling of the eaves tile according to the invention, its top forms the desired screen and protection against the ingress of small animals under the roof surface. For this reason, the foot fold conventionally provided at the lower edge is not necessary. However, nothing prevents, e.g. for reasons of higher strength or for support on the drying frames when manufacturing as pressed roof tiles, this foot rebate should continue to be provided. It goes without saying that the eaves tile according to the invention also has in its lower angled surface part the interlocking interlocking with the next adjoining eaves tiles in the side and cover rebate area and otherwise enables the same configuration for verge as before. The eaves tile according to the invention can be produced both in the pressing process as a clay roof tile and as a concrete roof tile.

Ausführungsbeispiele der Erfindung sind nachfolgend anhand der beiliegenden Zeichnungen näher erläutert. In den Zeichnungen zeigen:

  • Fig. 1 einen Längsschnitt (von oben nach unten) durch eine Traufkonstruktion mit einer halbrunden hängenden Dachrinne;
  • Fig. 2 eine Draufsicht in Richtung des Pfeiles II in Fig. 1 auf einen erfindungsgemässen Traufziegel, der bei der Traufkonstruktion nach Fig. 1 zur Anwendung kommt, und
  • Fig. 3 einen zu Fig. 1 analogen Längsschnitt durch eine abgewandelte Traufkonstruktion unter Anwendung einer anderen Ausführungsform eines erfindungs­gemässen Traufziegels.
Embodiments of the invention are explained below with reference to the accompanying drawings. The drawings show:
  • 1 shows a longitudinal section (from top to bottom) through an eaves construction with a semicircular hanging gutter.
  • Fig. 2 is a plan view in the direction of arrow II in Fig. 1 on an eaves tile according to the invention, which is used in the eaves construction according to Fig. 1, and
  • 3 shows a longitudinal section analogous to FIG. 1 through a modified eaves construction using another embodiment of an eaves tile according to the invention.

Die in Fig. 1 gezeigte Traufkonstruktion eines flach geneigten Daches weist eine auf den Sparren 1 angebrachte Schalung 2, ein auf der Schalung 2 befestigtes Keilstück 3 und eine auf diesem angebrachte Traufbohle 4 auf. Auf der Traufbohle 4 sind Rinnenhalter 5 befestigt, in denen eine Dachrinne 6 gelagert und in bekannter Weise bei 7 festgeklemmt ist. Die Rinnenhalter 5 sind zweckmässiger­weise in die Traufbohle 4 eingeklinkt.The eaves construction shown in FIG. 1 of a flat inclined roof has a formwork 2 attached to the rafters 1, a wedge piece 3 fastened to the formwork 2 and an eaves plank 4 attached to it. Gutter brackets 5 are fastened on the eaves board 4, in which a gutter 6 is mounted and clamped at 7 in a known manner. The gutter brackets 5 are expediently latched into the eaves board 4.

Das Dach ist mit Ton-Dachfalzziegeln 10 eingedeckt, von denen die unterste Reihe durch gesonderte Traufziegel 11 gebildet ist. Die Traufziegel 11 unterscheiden sich von den Flächenziegeln 10 im wesentlichen dadurch, daß sie in ihrem Längsverlauf nach unten abgeknickt sind und damit einen oberen Flächenteil 11a sowie einen unteren Flächenteil 11b bilden. In dem gezeigten Ausführungs­beispiel liegt die Knicklinie 12 in einem Abstand vom unteren Rand des Traufziegels 11, der etwa einem Viertel der Gesamtlänge der freiliegenden, d.h. nicht von Nachbar­ziegeln überdeckten Ziegeloberseite entspricht. Der Winkel, unter dem der untere Flächenteil 11b gegenüber dem oberen Flächenteil 11a nach unten abgeknickt ist, beträgt im gezeigten Ausführungsbeispiel etwa 45°. An seinem unteren Rand ist der Traufziegel 11 mit einem doppelten Fußfalz 13 versehen. Im übrigen entspricht der Trauf­ziegel 11 bezüglich seiner Verfalzung im Kopffalz-, Deckfalz- und Seitenfalzbereich sowie seiner Gestaltung auf der Ober- und Unterseite einem herkömmlichen Trauf­ziegel des Types "Karat 70" der Anmelderin und weist auf seiner Oberseite eine Spiegelfläche 14 auf, von der aus die für den "Karat 70" charakteristische weitgehend ebene Krempenfläche 15 nach oben vorspringt. Da der Dachziegel "Karat 70" hinreichend bekannt ist, bedarf seine weitere Ausgestaltung an dieser Stelle keiner näheren Erläuterung. Es versteht sich jedoch, daß die Erfindung nicht auf die Anwendung dieses speziellen Dachziegeltypes beschränkt ist, sondern auf jeden Dach­falzziegel anwendbar ist.The roof is covered with clay roofing tiles 10, of which the bottom row is formed by separate eaves tiles 11. The eaves tiles 11 differ from the surface tiles 10 essentially in that they are bent downwards in their longitudinal course and thus form an upper surface part 11a and a lower surface part 11b. In the exemplary embodiment shown, the crease line 12 lies at a distance from the lower edge of the eaves tile 11, which corresponds to approximately a quarter of the total length of the exposed top of the tile, ie not covered by neighboring tiles. The angle at which the lower surface part 11b relative to the upper Surface part 11a is kinked downward, is about 45 ° in the embodiment shown. At its lower edge, the eaves tile 11 is provided with a double rebate 13. Otherwise, the eaves tile 11 corresponds with respect to its interlocking in the top rebate, top rebate and side rebate area and its design on the top and bottom of a conventional eave tile of the type "Karat 70" of the applicant and has a mirror surface 14 on its top, from which the largely flat brim surface 15, which is characteristic of the "Karat 70", projects upwards. Since the "Karat 70" roof tile is well known, its further configuration requires no further explanation at this point. However, it is understood that the invention is not limited to the use of this particular type of roof tile, but is applicable to any roof tile.

Wie aus Fig. 1 deutlich wird, bildet der untere Flächen­teil 11b der Traufziegel 11 in Verbindung mit dem Doppel-Fußfalz 13 einen hinreichenden Schutz gegen eingewehtes Spritz- und Tropfwasser, ohne daß die Längsseite der Traufbohle 4 und die Stirnseiten der Keilstücke 3 durch ein Traufblech geschützt werden müssten. Die Schalung 2 ist hingegen durch eine herkömmliche Über­deckung 2′ aus Pappe geschützt. Der untere Flächenteil 11b entfaltet seine Schutzwirkung nicht nur aufgrund der abdeckenden Wirkung, sondern wesentlich dadurch, daß er gegenüber seitlich aus der Pfeilrichtung W anströmendem Wind eine Ablenkwirkung erzeugt, durch die sich in der Mulde der Dachrinne 6 eine verhältnismässig strömungsfreie Zone ausbildet. Aus diesem Grund sind die Traufziegel 11 auch gegen ein Abheben durch Windeinwirkung geschützt.As is clear from Fig. 1, the lower surface part 11b of the eaves tile 11 in connection with the double rebate 13 provides adequate protection against blowing spray and dripping water without the long side of the eaves board 4 and the end faces of the wedge pieces 3 by an eaves sheet would have to be protected. The formwork 2, however, is protected by a conventional cover 2 'made of cardboard. The lower surface part 11b develops its protective effect not only because of the covering effect, but essentially because it produces a deflecting effect with respect to the wind flowing laterally from the arrow direction W, through which a relatively flow-free zone is formed in the trough of the gutter 6. For this reason, the eaves tiles 11 are also protected against being lifted off by wind.

Die Fig. 3 zeigt eine Traufkonstruktion eines nicht über­stehenden Daches mit einer verdeckten Kastenrinne. Auch hier ist auf den Sparren 21 des Daches eine Bretterschalung 22 mit einer Pappabdeckung 22′ vorgesehen. Die Traufziegel­reihe ist durch Traufziegel 31 gebildet, die um eine etwa in der Längsmitte der nicht eingedeckten Ziegeloberseite querverlaufende Linie 32 nach unten abgewinkelt sind, und eine im Querschnitt an die Abwinkelung angepasste Trauf­bohle 24 dient zur Abstützung der Traufziegel 31 im Knick­bereich. Zwischen Schalung 22 und Traufbohle 24 sind die nicht näher bezeichneten Träger der Kastenrinne 26 befestigt, die auf ihrer Außenseite durch eine Attika 27 verdeckt ist.Fig. 3 shows an eaves construction of a roof not protruding with a hidden box gutter. Here too, a board formwork 22 with a cardboard cover 22 'is provided on the rafters 21 of the roof. The row of eaves bricks is formed by eaves bricks 31, which are angled downward about a line 32 running approximately in the longitudinal center of the uncovered brick upper side, and an eaves plank 24 which is adapted in cross-section to the bending serves to support the eaves bricks 31 in the buckling area. Between the formwork 22 and eaves 24, the unspecified supports of the box gutter 26 are fastened, which is covered on their outside by an attic 27.

Durch die Abwinkelung weisen auch die Traufziegel 31 jeweils einen oberen Flächenteil 31a und einen unteren Flächenteil 31b auf, wobei der untere Flächenteil 31b jedoch beträchtlich grösser als bei der Ausführungsform gemäß den Fig. 1 und 2 ist. Die Höhe der Traufbohle 24 ist so bemessen, daß der obere Flächenteil 31a die gleiche Neigung wie die darüber angeordneten Flächenziegel 30 hat, während der untere Flächenteil 31b unter einem Winkel von etwa 30° dazu geneigt ist. Auch hier ist erkennbar, daß die Traufziegel 31 deutlich in die Dachrinne 26 hineinragen und aufgrund des nach unten abgewinkelten Flächenteils 31b die Kante der Schalung und insbesondere die Traufbohle 24 vor Ein­wehungen schützen. In dem gezeigten Ausführungsbeispiel bildet bereits die Attika 27 der Kastenrinne 26 einen be­trächtlichen Windschutz; tritt jedoch an die Stelle dieser geschützten Kastenrinne 26 eine halbrunde Dachrinne 6 ent­sprechend dem Ausführungsbeispiel, so kann ohne die Gefahr eines Überschießens von herabströmendem Dachflächenwasser die Reihe der Traufziegel 31 noch näher an die Rinne heran­gerückt werden, so daß noch eine weitere Überdeckung die Folge ist.Due to the bending, the eaves bricks 31 also each have an upper surface part 31a and a lower surface part 31b, the lower surface part 31b, however, being considerably larger than in the embodiment according to FIGS. 1 and 2. The height of the eaves board 24 is dimensioned such that the upper surface part 31a has the same inclination as the surface tiles 30 arranged above it, while the lower surface part 31b is inclined at an angle of approximately 30 ° thereto. It can also be seen here that the eaves tiles 31 protrude clearly into the gutter 26 and, because of the downwardly angled surface part 31b, protect the edge of the formwork and in particular the eaves board 24 from blowing in. In the exemplary embodiment shown, the attic 27 of the box gutter 26 already forms a considerable wind protection; However, if this protected box gutter 26 is replaced by a semicircular gutter 6 according to the exemplary embodiment, the row of eaves tiles 31 can be moved even closer to the gutter without the risk of overflowing roof water, so that a further overlap is the result.

In dem Ausführungsbeispiel gemäß Fig. 3 weisen die Traufziegel 31 keine nach unten gerichtete Fußfalz­rippe auf, sondern laufen auf die Ziegeldicke aus. Es kann daran gedacht werden, im Knickbereich oder etwas nach oben versetzt auf der Unterseite des Flächenteils 31a geonderte Stützrippen auszubilden, mittels denen sich die Traufziegel auf der Traufbohle 24 abstützen können. Auch die Traufziegel 31 entsprechen, abgesehen von den vorstehend beschriebenen erfindungsgemässen Besonderheiten, bezüglich der weiteren Ausgestaltung ihrer Ober- und Unterseite sowie bezüglich der Ver­falzung im Kopf-, Seiten- und Deckfalzbereich dem Dach­ziegeltyp "Karat 70" der Anmelderin. Allerdings liegt aufgrund des flächenmässig grösseren unteren Flächen­teils 31b eine bei dem Ausführungsbeispiel gemäß den Fig. 1 und 2 über der Knicklinie 12 befindliche Wasser­ausführung 17 aus der Seitenverfalzung auf die Spiegel­fläche 14 bei der Ausführungsform gemäß Fig. 3 unterhalb der entsprechenden Knicklinie 32. Somit erfolgt eine bei Starkregen evtl. ins Gewicht fallende seitliche Einströmung dort erst im nach unten geneigten Teil des Traufziegels, was die strömungslenkende Wirkung des abgewinkelten Teils begünstigt.In the exemplary embodiment according to FIG. 3, the eaves bricks 31 do not have a downward rebate rib, but run down to the brick thickness. It can be considered to form separate support ribs in the kink area or slightly offset upwards on the underside of the surface part 31a, by means of which the eaves tiles can be supported on the eaves board 24. Apart from the special features according to the invention described above, the eaves tiles 31 also correspond to the applicant's "Karat 70" roof tile type with regard to the further configuration of their top and bottom sides and with respect to the folds in the top, side and cover rebate area. However, due to the larger area of the lower surface 31b, in the exemplary embodiment according to FIGS. 1 and 2, a water version 17 located above the fold line 12 from the side fold on the mirror surface 14 in the embodiment according to FIG. 3 lies below the corresponding fold line 32 in the event of heavy rain, there may be a significant lateral inflow only in the downward sloping part of the eaves tile, which favors the flow-guiding effect of the angled part.
