Abstract

This invention relates to a ridge tile which defines a ventilating gap between the outside surface of that end portion of the tile which is overlapped in the roof and the inside surface of the overlapping end portion of the adjacent ridge tile in that its end portion which is overlapped in the roof has a flat surface and the lower portions of the outside surface of its overlapped end portion define a clearance with the inside surface of the overlapping end portion of the adjacent ridge tile. It is an object of the invention to provide a ventilating ridge tile which is of the kind defined first hereinbefore and together with an adjacent ventilating ridge tile of the same kind defines a larger effective ventilating cross-sectional area whereas the external size and shape of the ventilating ridge tile are substantially preserved and the universal usability of the ventilating ridge time in a mortar bed or with unbonded joints on roof pane tiles or ridge-adjoining tiles is obstructed or reduced. This is accomplished in that the overlapped end portion of the ridge tile is provided with additional, outwardly sloping, flat surfaces between the surface at the apex of the tile and those portions which define a clearance with the adjacent ridge tile.

Description

Die Erfindung bezieht sich auf einen Firstziegel nach dem Oberbegriff des Anspruchs 1.The invention relates to a ridge tile according to the preamble of claim 1.

Die mit den aus den DE-PS 19 49 355 und 19 55 924 bekannten Firstziegeln dieser Gattung erzielbaren Entlüftungsquerschnitte sind pro laufenden Meter beschränkt. Ferner werden die in der DIN 4108 "Wärmeschutz im Hochbau", Teil 3, "Klimabedingter Feuchteschutz", vorgeschriebene Entlüftungsquerschnitte von 0,5 o/oo der dazugehörigen Dachfläche mit Lüftungs-Firstziegeln üblicher Größe nur für Sparrenlängen bis ca. 6 m erreicht. Bei einem Satteldach mit 2 x 6 m Sparrenlänge ist also ein Lüftungsquerschnitt am First von ca. 60 cm' pro laufenden Meter First erforderlich, der mit den oben genannten bekannten Firstziegeln erzielbar ist. Bei größeren Sparrenlängen ist bisher die zusätzliche Verdeckung von konventionellen Gaupenlüftern oder Firstanschlußlüftern in Firstnähe erforderlich, die den fünf- bis zehnfachen Preis eines normalen Mittelfelddachziegels haben und dadurch die Kosten eines Daches mit langen Sparren stark erhöhen.The ventilation cross sections achievable with the ridge tiles of this type known from DE-PS 19 49 355 and 19 55 924 are limited per running meter. Furthermore, the ventilation cross-sections specified in DIN 4108 "Thermal protection in building construction", Part 3, "Climate-related moisture protection", of 0.5 o / oo of the associated roof area with ventilation ridge tiles of the usual size can only be achieved for rafter lengths of up to approx. 6 m. In the case of a saddle roof with a rafter length of 2 x 6 m, a ventilation cross-section on the ridge of approx. 60 cm 'per running meter of ridge is required, which can be achieved with the known ridge tiles mentioned above. In the case of larger rafter lengths, the additional covering of conventional dormer fans or ridge connection fans near the ridge has so far been required, which have five to ten times the price of a normal middle field roof tile and thereby greatly increase the cost of a roof with long rafters.

Eine über die übliche Firstziegel-Breite deutlich hinausgehende Verbreiterung der aus den oben genannten Patentschriften bekannten Lüftungs-Firstziegel ist aus optischen Gründen nicht anzustreben und aus fertigungs- und anwendungstechnischen Gründen nachteilig, so daß eine Vergrößerung des Entlüftungsquerschnittes pro Firstziegelpaar bzw. pro laufenden Meter nur sehr beschränkt möglich und mit erheblichen Nachteilen verbunden wäre.A widening of the ventilation ridge tiles known from the above-mentioned patents, which goes well beyond the usual ridge tile width, is not desirable for optical reasons and is disadvantageous for reasons of production and application technology, so that an increase in the ventilation cross section per pair of ridge tiles or per running meter is very limited limited possible and would be associated with considerable disadvantages.

Eine unter die übliche Firstziegel-Decklänge von 33 cm gehende Verkürzung der aus den oben genannten Patentschriften bekannten Lüftungs-Firstziegel ist ebensowenig anzustreben, da sie eine Erhöhung der erforderlichen Stückzahl von Firstziegeln und damit eine erhebliche Kostenerhöhung verursachen würde. Immerhin liegt der Kostenanteil von vergleichbaren Firstziegeln bereits bei 10 % der gesamten Dachziegelkosten.An under the usual ridge tile deck length of 33 cm continuous shortening of the known from the above patents L üftungs ridge tile is desirable as little, as it would cause an increase of the required number of ridge tiles and thereby a substantial increase in cost. After all, the cost share of comparable ridge tiles is already 10% of the total roof tile costs.

Der Erfindung liegt die Aufgabe zugrunde, den wirksamen Lüftungsquerschnitt eines Firstziegelpaares der eingangs definierten Gattung unter weitgehender Beibehaltung seiner äußeren Größe und Form zu vergrößern, ohne daß die universelle Verdeckbarkeit in Mörtelbett oder trocken auf Flächendachziegeln oder Firstanschlußziegeln behindert oder verschlechtert wird.The invention is based on the object, the effective ventilation area to enlarge a ridge tile pair of the above-defined genus while largely retaining its external size and shape without the universal hidability in mortar bed or dry on surface of tiles or F hindered irstanschlußziegeln or is deteriorated.

Die Lösung der gestellten Aufgabe erfolgt gemäß dem Kennzeichen des Patentanspruchs 1. Der erfindungsgemäße Firstziegel hat den Vorteil, daß ohne Einschränkung des unteren Lichtraumprofils des überdeckten Endes des Firstziegels an der Stelle, an welcher der Kopf eines steil verdeckten Dachziegels den Firstziegel berührt, die seitlich abfallenden Abflachungen eines zusätz-lichen Lüftungsquerschnitt schaffen.The object is achieved according to the characterizing part of patent claim 1. The ridge tile according to the invention has the advantage that without restricting the lower clearance profile of the covered end of the ridge tile at the point where the head of a steeply covered roof tile touches the ridge tile, the sloping sides Create flats of an additional ventilation cross section.

Eine verbesserte Ausführungsform der Erfindung ist Gegenstand des Patentanspruchs 2. Durch die Nut ist eine sichere Ableitung von Regen- und Schmelzwasser über die beiderseitigen Randabschnitte bis auf die Dachfläche gewährleistet. Durch teilweisen oder völligen Verzicht auf die Rippe wird der wirksame Lüftungsquerschnitt weiter vergrößert.An improved embodiment of the invention is the subject of claim 2. The groove ensures safe drainage of rain and melt water over the bilateral edge sections up to the roof surface. By partially or completely dispensing with the rib, the effective ventilation cross-section is further increased.

Eine weitere Ausgestaltung des erfindungsgemäßen Firstziegels ist Gegenstand des Patentanspruchs 3. Die dort genannte Versteifungs-Rippe hat den Vorteil, daß sie das Ende des Firstziegels derart versteift, daß nicht nur der Scherben dünner gemacht werden kann, was den Lüftungsquerschnitt weiter vergrößert, sondern ggf. sogar auf die den Lüftungsquerschnitt verengende, außen umlaufende Rippe bzw. deren versteifende Wirkung überhaupt verzichtet werden kann.Another embodiment of the ridge tile according to the invention is the subject of claim 3. The stiffening rib mentioned there has the advantage that it stiffens the end of the ridge tile in such a way that not only the fragments are thinner can be made, which further increases the ventilation cross-section, but may even be able to do without the rib that narrows the ventilation cross-section and encircles the outside or its stiffening effect.

Eine weitere Ausgestaltung eines Firstziegels nach Anspruch 3 ist Gegenstand des Patentanspruchs 4. Diese bevorzugte Ausführungsform hat den Vorteil, daß die Biegesteifigkeit und Bruchfestigkeit im besonders beanspruchten und gefährdeten Mittelbereich stark erhöht wird, ohne daß die Höhe des unteren Lichtraumprofiles in den weiter außen liegenden Bereichen wesentlich eingeschränkt wird. Die Bruchfestigkeit des Firstziegels ist nicht nur im verdeckten Zustand von Bedeutung; Vielmehr spielt seine Steifigkeit auch im weichen Zustand nach der Verpressung im Hinblick auf Fertigungstoleranzen und Bruchrate eine wesentliche Rolle.A further embodiment of a ridge tile according to claim 3 is the subject of claim 4. This preferred embodiment has the advantage that the bending stiffness and breaking strength in the particularly stressed and endangered central area is greatly increased without the height of the lower clearance profile in the areas lying further out significantly is restricted. The breaking strength of the ridge tile is not only important when it is concealed; Rather, its stiffness also plays an important role in the soft state after pressing in terms of manufacturing tolerances and breakage rate.

Patentanspruch 5 bezieht sich auf einen patentgemäßen Firstziegel, dessen überdecktes Ende im Bereich der Stirnfläche des überdeckenden Endes des benachbarten Firstziegels im Querschnitt satteldachartig ausgebildet ist und mit seinem Scheitel ein Auflager für das überdeckende Ende des benachbarten Firstziegels bildet. Firstziegel mit den Gattungsmerkmalen dieses Anspruchs sind bereits aus der oben genannten DE-PS 19 55 924 bekannt. Die Verbesserung dieses bekannten Firstziegels gemäß dem Kennzeichen des Patentanspruchs 5 hat den Vorteil, daß am Übergang vom einfachen, waagerecht liegenden Lüftungs-Querschnitt zu den beiderseitigen, geteilten Lüftungs-Querschnitten links und rechts des satteldachartigen Teiles keine hinderliche Querschnittsverengung auftreten kann.Claim 5 relates to a ridge tile according to the patent, the covered end of which is formed in cross section in the area of the end face of the covering end of the adjacent ridge tile and forms a support for the covering end of the adjacent ridge tile with its apex. Ridge tiles with the generic features of this claim are already known from the above-mentioned DE-PS 19 55 924. The improvement of this known ridge tile according to the characterizing part of claim 5 has the advantage that at the transition from the simple, horizontal ventilation cross-section to the bilateral, divided ventilation cross-sections to the left and right of the gable roof-like part, no obstructive cross-sectional constriction can occur.

Eine weitere besonders vorteilhafte Ausführungsform der Erfindung ist Gegenstand von Patentanspruch 6. Dieser vermittelt den Vorteil, daß eine gegenseitige Längsverriegelung der Firstziegel gewährleistet ist, ohne daß zusätzliche Rippen an der Außfenfläche des überdeckten Endes nötig sind.Another particularly advantageous embodiment of the invention is the subject of claim 6. This gives the advantage that a mutual longitudinal locking of the Ridge tile is guaranteed without the need for additional ribs on the outer surface of the covered end.

Der Firstziegel nach Patentanspruch 7 hat den Vorteil, daß unter Beibehaltung des Querschnittes seines überdeckten Teiles der wirksame Lüftungsquerschnitt des Firstziegelpaares ohne wesentliche Änderung der äußeren Form erheblich vergrößert wird.The ridge tile according to claim 7 has the advantage that, while maintaining the cross section of its covered part, the effective ventilation cross section of the ridge tile pair is significantly increased without a significant change in the outer shape.

Durch die vorgeschriebenen erfindungsgemäßen Verbesserungen ergibt sich zusammen bereits mehr als eine Verdoppelung des Lüftungsquerschnittes, ohne daß Mehrkosten anfallen. Dies entspricht bei einem Satteldach einer zulässigen Sparrenlänge von beiderseits ca. 13 m.The prescribed improvements according to the invention already result in more than doubling the ventilation cross-section without incurring additional costs. With a saddle roof, this corresponds to a permissible rafter length of approx. 13 m on both sides.

Eine weitere wesentliche Erhöhung des Lüftungsquerschnitts pro laufenden Meter First ist darüberhinaus durch Patentanspruch 8 möglich, und zwar wiederum ohne Änderung seines Querschnittes. Durch diese Verkürzung des Firstziegels kann dann gegebenenfalls, allerdings unter Inkaufnahme von Mehrkosten, eine weitere Steigerung des Lüftungsquerschnitte- pro laufenden Meter First erreicht werden.A further significant increase in the ventilation cross section per running meter ridge is also possible by claim 8, again without changing its cross section. This shortening of the ridge tile can then result in a further increase in the ventilation cross-sections - per running meter of ridge - if necessary, but at the cost of additional costs.

Der erfindungsgemäße Firstziegel ist in der nachstehenden Beschreibung anhand der Zeichnung beispielhaft näher erläutert.The ridge tile according to the invention is explained in more detail in the following description using the drawing as an example.

The drawing shows:
  • Figure 1 shows a cross section through the mutually overlapping ends of two ridge tiles according to the invention, in the left or right half in different embodiments.
  • FIG. 2 shows a longitudinal section through a ridge tile in the central axis of FIG. 1;

Der Bereich der gegenseitigen Uberdeckung zweier Firstziegel 1, 2 ist aus Fig. 1 und 2 ersichtlich. Der Firstziegel 1 bildet zwischen der Außenseite seines in der Eindeckung überdeckten Endes 3 und der Innenseite des überdeckenden Endes 4 des benachbarten Firstziegels 2 einen Lüftungsspalt 5, und zwar dadurch, daß sein in der Eindeckung überdecktes Ende 3 im Scheitelbereich eine Abflachung 6 aufweist. Die der Dachfläche zugekehrten Abschnitte 7 der Außenseite seines überdeckten Endes 3 liegen jedoch mit Spiel an der Innenseite des überdeckenden Endes 4 des benachbarten Firstziegels 2 an. Das überdeckte Ende 3 des Firstziegels 1 weist zwischen seiner Abflachung 6 im Scheitelbereich und seinen mit Spiel am benachbarten Firstziegel 2 anliegenden Abschnitten 7 weitere, nach außen abfallende Abflachungen 8,9 auf. Auf diese Weise ist ohne Einschränkung des unteren Lichtraumprofils 10 des überdeckten Endes des Firstziegels 2 an der Stelle 11, an welcher der Kopf 12 eines steil verdeckten Dachziegels 13 den Firstziegel berührt, durch die seitlich nach außen abfallenden Abflachungen 8, 9 ein zusätzlicher Lüftungsquerschnitt 14 geschaffen.The area of mutual overlap of two ridge tiles 1, 2 can be seen from FIGS. 1 and 2. The ridge tile 1 forms a ventilation gap 5 between the outside of its end 3 covered in the covering and the inside of the covering end 4 of the adjacent ridge tile 2, specifically in that its end 3 covered in the covering has a flattening 6 in the apex region. The sections 7 facing the roof surface on the outside of its covered end 3, however, rest with play on the inside of the covering end 4 of the adjacent ridge tile 2. The covered end 3 of the ridge tile 1 has between its flattening 6 in the apex area and its sections 7 which rest with play on the adjacent ridge tile 2, further flats 8,9 falling outwards. In this way, an additional ventilation cross-section 14 is created without restriction of the lower clearance profile 10 of the covered end of the ridge tile 2 at the point 11 at which the head 12 of a steeply covered roof tile 13 touches the ridge tile, through the flats 8, 9 that drop off to the outside .

Das in der Eindeckung überdeckte Ende 3 des Firstziegels 1 weist neben seiner Stirnfläche 15 eine Rippe 16 auf. Diese kann aber teilweise oder ganz entfallen, wenn sie durch eine umlaufende Nut 17 ersetzt wird, in der anfallendes Regen-oder Schmelzwasser über die beiderseitigen Ränder 27 bis auf die Dachfläche abgeleitet wird. Durch den Wegfall der Rippe 16 wird der Lüftungsquerschnitt 14 weiter vergrößert. Zweckmäßigerweise wird dabei zur Versteifung des überdeckten Endes 3 eine nach innen vorspringende Rippe 18 angebracht, die im Mittelbereich 19 höher ausgebildet ist. Dadurch ist gewährleistet, daß das Lichtraumprofil 10 an der Stelle 11 nicht zu stark eingeschränkt wird, an welcher die Köpfe 12 von steil verdeckten Dachziegeln 13 den Firstziegel 1 vorzugsweise berühren. Der satteldachartige Teil 20 kann auch viel steiler als im Stand der Technik angeordnet sein und ist im Extremfall als Mittelstützrippe 21 ausgebildet. Der gegenseitigen Längsverriegelung der Firstziegel 1, 2 dienen die Rippen 24, die im Bereich der den Dachflächen zugekehrten Abschnitten 22, 23 des überdeckenden Endes 4 angebracht sind und in die Nut 17 des überdeckten Endes 3 eingreifen.The end 3 of the ridge tile 1 covered in the covering has a rib 16 in addition to its end face 15. However, this can be omitted partially or completely if it is replaced by a circumferential groove 17 in which rain or melt water is drained off via the edges 27 on both sides up to the roof surface. By eliminating the rib 16, the ventilation cross section 14 is further enlarged. Appropriately, an inwardly projecting rib 18 is attached to stiffen the covered end 3, which is formed higher in the central region 19. This ensures that the clearance profile 10 is not restricted too much at the point 11 at which the heads 12 of steeply covered roof tiles 13 preferably touch the ridge tile 1. The gable roof-like part 20 can also be arranged much steeper than in the prior art and in the extreme case is designed as a central support rib 21. The mutual longitudinal locking of the ridge tiles 1, 2 is served by the ribs 24, which are attached in the region of the sections 22, 23 of the covering end 4 facing the roof surfaces and engage in the groove 17 of the covered end 3.

In Fig. 3 a ist im Querschnitt die ha 1be Gesamtbreite 25 eines Firstziegels und in Fig. 3 b im Längsschnitt die Decklänge 2.6 dargestellt.In Fig. 3 a the h a 1be total width 25 of a ridge tile is shown in cross section and in Fig. 3 b the top length 2.6 is shown in longitudinal section.

In Fig. 4 ist in der rechten Häl.fte der ursprüngliche Lüftungsquerschnitt 28 eines Firstziegels des eingangs als bekannt vorausgesetzten Standes der Technik dargestellt; der Querschnitt kann vergleichsweise mit 100 % angesetzt werden. In der linken Hälfte sind der ursprüngliche Querschnitt 28 und die durch die erfindungsgemäßen Verbesserungen zusätzlich gewonnenen Lüftungsquerschnitt 29, 30 und 31 dargestellt. Der Querschnitt 29 ergibt sich aus der Abschrägung des Seitenbereiches und entspricht einer Vergrößerung von ca. 39 %, der Querschnitt 30 ergibt sich aus der Nut 17 und entspricht einer Vergrößerung von ca. 23 %, der Querschnitt 31 ergibt sich aus der Vergrößerung der Höhe des überdeckenden Endes und entspricht hier ca. 39 % Vergrößerung.In FIG. 4 in the right Häl.fte the original L is üftungsquerschnitt 28 of a ridge tile shown initially assumed to be known of the prior art; the cross-section can be comparatively set at 100%. In the left half, the original cross section 28 and the ventilation cross sections 29, 30 and 31 additionally obtained by the improvements according to the invention are shown. The cross section 29 results from the beveling of the side area and corresponds to an enlargement of approx. 39%, the cross section 30 results from the groove 17 and corresponds to an enlargement of approx. 23%, the cross section 31 results from the enlargement of the height of the overlapping end and corresponds here to an approx. 39% enlargement.

Die gesamte Querschnittsvergrößerung liegt bei über 100 %. Dabei sind die Gesamtbreite, das erforderliche Lichtraumprofil 10 und das gesamte äußere Erscheinungsbild des Lüftungsfirstziegels unverändert beibehalten.The overall cross-sectional enlargement is over 100%. The overall width, the required clearance profile 10 and the overall external appearance of the ventilation ridge tile are retained unchanged.
