Description

Die Erfindung betrifft eine Dacheindeckungsplatte, insbesondere aus Beton, mit zumindest einem die Festigkeit verstärkenden Vorsprung auf der Unterseite und einer auf ihrer Oberseite etwa in Längsmitte in Längsrichtung der Dacheindeckungsplatte angeordneten Halterung für ein Dachzubehörteil, wobei die Halterung an ihrem traufseitigen Ende ein nach oben weisendes im wesentlichen als Stumpf einer Pyramide ausgebildetes Horn aufweist und an der zum First weisenden Fläche des Horns zumindest ein erstes Befestigungselement sowie am firstseitigen Ende der Halterung auf deren Oberseite ein zweites Befestigungselement vorgesehen ist und im Bereich der Befestigungselemente Anlageflächen für ein Zubehörteil vorgesehen sind.The invention relates to a roof covering plate, in particular made of concrete, with at least one strength-enhancing projection on the underside and a holder for a roof accessory part arranged on its upper side approximately in the longitudinal center in the longitudinal direction of the roof covering plate, the holder at its eaves-side end facing upwards essentially has a horn formed as a truncated pyramid and at least a first fastening element is provided on the surface of the horn facing the ridge and a second fastening element is provided on the top of the holder on the ridge side and contact surfaces for an accessory are provided in the region of the fastening elements.

Aus der DE-A-3 824 808 ist ein Halter für Sicherheits-Steigtritte, Laufroste und Schneefänger bekannt, der auf einer handelsüblichen Dachpfanne aufliegt und ein Hakenteil aufeist, das die Dachpfanne an ihrem firstseitigen Ende sowie die dort befindliche Dachlatte U-förmig umgreift.From DE-A-3 824 808 a holder for safety climbing steps, gratings and snow catchers is known, which rests on a commercially available roof tile and has a hook part that grips around the roof tile at its first side end and the roof batten located there in a U-shape.

Aus der EP-A 0 499 145 ist eine derartige Dacheindeckungsplatte bekannt, die aus dünnwandigem Material besteht, und bei der die Halterung einstückig angeformt ist. Auf das Horn kann ein Dachzubehörteil wie eine Schneefanggitterstütze oder ein Rundholzhalter aufgesteckt werden. Mit den Befestigungselementen kann ein auf den Anlageflächen aufliegendes Dachzubehörteil wie ein Standbrettbügel an der Halterung befestigt werden. Die Dacheindeckungsplatte besteht vorzugsweise aus einer Aluminiumlegierung.From EP-A 0 499 145 such a roofing plate is known, which consists of thin-walled material, and in which the bracket is integrally formed. A roof accessory such as a snow guard support or a log holder can be attached to the horn. With the fastening elements, a roof accessory part lying on the contact surfaces can be fastened to the bracket like a stand board bracket. The roof covering plate is preferably made of an aluminum alloy.

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Dacheindeckungsplatte zu verbilligen und dennoch eine dauerhaft und sicher befestigte Halterung zur Verfügung zu stellen.The invention has for its object to cheapen the known roofing plate and still one to provide a permanently and securely fastened bracket.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Halterung mit ihrem Rand auf der Oberseite der Dacheindeckungsplatte aufgesetzt ist, daß auf der Oberseite der Dacheindeckungsplatte eine der Kontur des Randes der Halterung entsprechende Auflagefläche eingeprägt ist und innerhalb dieser Auflagefläche ein erhöhter Bereich angeformt ist, der in die Halterung formschlüssig eingreift und daß die Halterung an der Dacheindeckungsplatte mit zumindest einem unlösbaren Verbindungselement befestigt ist.According to the invention, the object is achieved in that the holder is placed with its edge on the top of the roof covering plate, that on the top of the roof covering plate a bearing surface corresponding to the contour of the edge of the holder is embossed and an elevated area is formed within this bearing surface the bracket engages positively and that the bracket is attached to the roofing panel with at least one non-detachable connecting element.

Die Halterung der erfindungsgemäßen Dacheindeckungsplatte liegt zumindest mit ihrem unten überstehenden Rand auf der diesem angepaßten Auflagefläche der Dacheindeckungsplatte auf. An seiner Innenseite liegt der Rand der Halterung an dem erhöhten Bereich innerhalb der Auflagefläche formschlüssig an, so daß die Halterung in Längs- und Querrichtung lagefixiert ist. Diese Ausführung hat den Vorteil, daß eine einzige Ausführung der Halterung für Dacheindeckungsplatten mit verschiedener Profilierung verwendbar ist, außerdem verhindert der erhöhte Bereich das Eindringen von Wasser am unlösbaren Verbindungselement.The holder of the roof covering plate according to the invention lies, at least with its edge protruding below, on the support surface of the roof covering plate which is adapted to this. On its inside, the edge of the holder lies in a form-fitting manner against the raised area within the support surface, so that the holder is fixed in position in the longitudinal and transverse directions. This version has the advantage that a single version of the holder can be used for roofing panels with different profiles, and the increased area prevents water from penetrating the non-detachable connecting element.

Die Formung der Auflagefläche kann beispielsweise an einem im Strangpreßverfahren auf einer Unterform hergestellten Betondachstein dadurch erfolgen, daß in die frische Betonschicht ein Prägewerkzeug eingedrückt wird, dessen Kontur dem Rand der Halterung entspricht. Somit sind die für die Ausrüstung mit einer Halterung vorgesehenen Betondachsteine mit der üblichen maschinellen Einrichtung herstellbar, der Rohling ist lediglich vor der Aushärtung in einem Zwischenschritt auf der Oberseite entsprechend zu formen. Beim Eindrücken des Prägewerkzeugs wird nur sehr wenig Material verdrängt, das in den Bereich des innerhalb der Ausformung vorgesehenen erhöhten Bereichs gelangt, der in die Halterung formschlüssig eingreift. In der Unterform ist eine dem die Festigkeit verstärkenden Vorsprung auf der Unterseite der Dacheindeckungsplatte entsprechende Aussparung vorzusehen. Die Befestigung der Halterung an der Dacheindeckungsplatte mit einem oder mehreren unlösbaren Verbindungselementen hat den Vorteil, daß gegenüber der üblichen Schraubverbindung weder eine Lockerung im Lauf der Zeit, noch eine unbefugte Manipulation stattfinden kann.The support surface can be formed, for example, on a concrete roof tile produced by extrusion on a lower mold by pressing an embossing tool into the fresh concrete layer, the contour of which corresponds to the edge of the holder. Thus, the concrete roof tiles provided for fitting with a holder can be produced with the usual mechanical equipment; the blank is only to be shaped accordingly in an intermediate step on the upper side before curing. When the embossing tool is pressed in, only very little material is displaced, which reaches the area of the raised area provided within the formation, which engages in the holder with a positive fit. In the lower form one is the one Strength-enhancing projection on the underside of the roof covering plate to provide a corresponding recess. Fastening the bracket to the roof covering plate with one or more non-detachable connecting elements has the advantage that, compared to the usual screw connection, neither loosening over time nor unauthorized manipulation can take place.

Das unlösbare Verbindungselement kann eine Niete sein. Dadurch ist es möglich, die Halterung werkseitig an der ausgehärteten Dacheindeckungsplatte zu befestigen, wobei die Nietung mit einer definierten Kraft ausgeführt wird. Somit ist eine Beschädigung der Dacheindeckungsplatte durch Ausübung einer zu großen Kraft ebenso ausgeschlossen wie eine zu lockere Befestigung der Halterung. Die Niete kann die Halterung und die Dacheindeckungsplatte durchsetzen.The permanent connector can be a rivet. This makes it possible to attach the bracket to the hardened roof covering plate at the factory, the riveting being carried out with a defined force. Damage to the roof covering plate due to the exertion of too great a force as well as an excessively loose fastening of the holder are thus excluded. The rivet can penetrate the bracket and the roof covering plate.

Vorzugsweise ist das Formende der Niete hohl ausgeführt. Wenn der Kopf der Niete auf der Oberseite der Halterung angeordnet ist, kann bei der Herstellung der Nietverbindung eine Unterlegscheibe auf das Formende der Niete aufgeschoben und anschließend der überstehende Endabschnitt umgebördelt werden. Dadurch wird verhindert, daß der Durchmesser der Niete im Bereich der Dacheindeckungsplatte zunimmt und ein Lochleibungsdruck ausgeübt wird.The shape of the rivet is preferably hollow. If the head of the rivet is arranged on the upper side of the holder, a washer can be pushed onto the form end of the rivet during the production of the rivet connection and the protruding end section can then be flanged. This prevents the diameter of the rivets from increasing in the area of the roof covering plate and exerting a soffit pressure.

Anstelle einer Niete kann als unlösbares Verbindungselement auf der Unterseite der Halterung ein den Rand überragender Zapfen vorgesehen sein, der die Dacheindeckungsplatte durchdringt und auf deren Unterseite wie vorstehend beschrieben vernietet wird. Es ist auch möglich, mit dem Zapfen ein entsprechendes Gegenstück beispielsweise durch Kleben oder Schweißen, insbesondere durch Reibschweißen, unlösbar zu verbinden.Instead of a rivet, a pin projecting beyond the edge, which penetrates the roof covering plate and is riveted to the underside thereof as described above, can be provided as a permanent connection element on the underside of the holder. It is also possible to permanently connect a corresponding counterpart to the pin, for example by gluing or welding, in particular by friction welding.

Zur Übertragung großer Kräfte, beispielsweise bei Montage eines Standbretts auf der Halterung, kann die Halterung im Querschnitt etwa hutförmig mit verbreitertem Rand ausgebildet sein, so daß eine größere Fläche zur Kraftübertragung zur Verfügung steht.In order to transmit large forces, for example when mounting a standing board on the holder, the holder can have an approximately hat-shaped cross section with a widened edge be so that a larger area is available for power transmission.

Die Halterung kann aus Kunststoff, insbesondere faserverstärktem Kunststoff, oder aus einer Aluminiumlegierung bestehen.The holder can be made of plastic, in particular fiber-reinforced plastic, or of an aluminum alloy.

Eine besonders geeignete Aluminiumlegierung enthält etwa 10 bis 11,5% Silizium, etwa 1,8 bis 2,4% Kupfer und etwa 0,7 bis 1% Eisen.A particularly suitable aluminum alloy contains about 10 to 11.5% silicon, about 1.8 to 2.4% copper and about 0.7 to 1% iron.

Auf das nach oben weisende Horn am traufseitigen Ende der Halterung kann Dachzubehör wie die Sütze eines Schneefangitters oder eines Schneefangbalkens aufgesteckt werden. Eine werkzeugfreie Montage des Dachzubehörs ist möglich, wenn das Horn im wesentlichen als Stumpf einer vierseitigen Pyramide ausgebildet ist und zumindest an einer Seitenfläche eine Stufe zur rastenden Arretierung von Dachzubehör aufweist.Roof accessories such as the support of a snow guard or a snow guard beam can be attached to the upward-facing horn on the eaves-side end of the bracket. A tool-free installation of the roof accessories is possible if the horn is essentially designed as a stump of a four-sided pyramid and has a step at least on one side surface for locking the roof accessories.

Die Halterung ist universell auch zur Befestigung des Bügels einer Trittplatte oder eines Standbretts verwendbar, weil an der zum First weisenden Fläche des Horns zumindest ein erstes Befestigungselement sowie am firstseitigen Ende der Halterung auf deren Oberseite ein zweites Befestigungselement vorgesehen ist und im Bereich der Befestigungselemente Anlageflächen für ein Zubehörteil vorgesehen sind.The holder can also be used universally for fastening the bracket of a footboard or a standing board, because at least a first fastening element is provided on the surface of the horn facing the ridge and a second fastening element is provided on the top of the holder on the ridge side and contact surfaces for fastening elements in the area of the fastening elements an accessory is provided.

Die Befestigungselemente können als Gewindebolzen ausgebildet sein, deren Achsen radial zum Mittelpunkt eines Kreisbogens verlaufen, welcher der Unterkontur eines in der Neigung verstellbaren Zubehörteils, insbesondere der Unterkontur eines Standbrettbügels entspricht und daß die Anlageflächen konkavzylindrisch geformt sind.The fastening elements can be designed as threaded bolts, the axes of which run radially to the center of a circular arc which corresponds to the subcontour of an accessory part adjustable in inclination, in particular the subcontour of a stand board bracket, and that the contact surfaces are concavely cylindrical.

Üblicherweise ist im Standbrettbügel für ein Befestigungselement ein Langloch und für das andere Befestigungselement eine Reihe von Rundlöchern vorgesehen. Auf die Ausbildung beider Befestigungselemente kann verzichtet werden, wenn eines der Befestigungselemente, vorzugsweise das an der zum First weisenden Fläche des Horns angeordnete erste Befestigungselement T-förmig mit in Querrichtung angeordnetem Knebel ausgebildet ist, wobei der Abstand zwischen Anlagefläche und Unterseite des Knebels gleich der Dicke des Befestigungsbügels und die Breite des Knebels kleiner oder gleich der Breite des Langlochs ist. Die Achse des Halses des T-förmigen Befestigungselements verläuft radial zum Mittelpunkt eines Kreisbogens, welcher der Unterkontur eines Standbrettbügels entspricht.Usually, an elongated hole is provided in the standboard bracket for one fastening element and a series of round holes for the other fastening element. On the formation of both fastening elements can be dispensed with if one of the fastening elements, preferably the first fastening element arranged on the surface of the horn facing the ridge, is T-shaped with a toggle arranged in the transverse direction, the distance between the contact surface and the underside of the toggle being equal to the thickness of the Mounting bracket and the width of the toggle is less than or equal to the width of the slot. The axis of the neck of the T-shaped fastening element runs radially to the center of a circular arc which corresponds to the lower contour of a stand board bracket.

So kann der Befestigungsbügel auf das T-förmige Befestigungselement mit seinem Langloch in Querrichtung aufgesetzt und nach Schwenken in Längsrichtung mit dem anderen Befestigungselement durch eines der Rundlöcher verbunden werden.The fastening bracket can be placed on the T-shaped fastening element with its elongated hole in the transverse direction and, after pivoting in the longitudinal direction, connected to the other fastening element by one of the round holes.

Die Dacheindeckungsplatte kann mit Nägeln, Schrauben oder dergleichen an der Unterkonstruktion des Daches befestigt werden, wenn am firstseitigen Ende der Dacheindeckungsplatte Löcher vorgesehen sind.The roof covering plate can be fastened to the substructure of the roof with nails, screws or the like if holes are provided at the ridge-side end of the roof covering plate.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher erläutert wird.In the drawing, a preferred embodiment of the invention is shown, which is explained in more detail below.

Der Kopf 32 eines jeden als Niete ausgeführten Verbindungselementes 22 ist auf der Oberseite der Halterung 12 angeordnet. Das Formende 34 ist hohl ausgeführt und auf einer Unterlegscheibe 36 umgebördelt.The head 32 of each connecting element 22 designed as a rivet is arranged on the top of the holder 12. The mold end 34 is hollow and flanged on a washer 36.

Die Halterung 12 ist an ihrem traufseitigen Ende mit einem nach oben weisenden im wesentlichen als Stumpf einer vierseitigen Pyramide ausgebildeten Horn 38 zum Aufstecken von Dachzubehör versehen.The holder 12 is provided at its eaves-side end with an upward-facing horn 38, essentially designed as a stump of a four-sided pyramid, for attaching roof accessories.

An der zum First weisenden Fläche des Horns 38 ist ein als Gewindebolzen ausgebildetes erstes Befestigungselement 40 sowie am firstseitigen Ende der Halterung 12 auf deren Oberseite ein ebenfalls als Gewindebolzen ausgebildetes zweites Befestigungselement 42 angeordnet. Die Achsen der Befestigungselemente 40, 42 verlaufen radial zum Mittelpunkt 44 eines Kreisbogens 46, welcher der Unterkontur eines in der Neigung verstellbaren Standbrettbügels entspricht. Im Bereich der Befestigungselemente 40, 42 sind der Unterkontur des Standbrettbügels angepaßte konkavzylindrisch geformte Anlageflächen 48, 50 vorhanden.On the surface of the horn 38 facing the ridge there is a first fastening element 40 which is designed as a threaded bolt, and on the top side of the holder 12 on the upper side thereof is also a threaded bolt second fastening element 42 arranged. The axes of the fastening elements 40, 42 extend radially to the center 44 of an arc 46 which corresponds to the lower contour of a stand board bracket which is adjustable in inclination. In the area of the fastening elements 40, 42, there are concave-cylindrical contact surfaces 48, 50 which are adapted to the lower contour of the stand board bracket.

Fig. 2 zeigt die Dacheindeckungsplatte 10 aus Fig. 1 im Querschnitt in Blickrichtung zur Traufe hin. In dieser Fig. ist deutlich zu erkennen, daß die Auflagefläche 18 im Bereich der Mittelkrempe 52 der Dacheindeckungsplatte 10 angeordnet ist. Die Halterung 12 ist im Querschnitt etwa hutförmig mit einem durch eine Abwinkelung 54 zur Außenseite hin verbreiterten Rand 16 ausgebildet.FIG. 2 shows the roof covering plate 10 from FIG. 1 in cross section in the viewing direction towards the eaves. It can be clearly seen in this figure that the bearing surface 18 is arranged in the region of the central rim 52 of the roof covering plate 10. The bracket 12 is approximately hat-shaped in cross section with an edge 16 widened toward the outside by an angled portion 54.

In Fig. 3 ist in der Unteransicht der Dacheindeckungsplatte 10 die Form des die Festigkeit verstärkenden Vorsprungs 14 erkennbar, der sich unterhalb der Mittelkrempe 52 vom firstseitigem Ende 24 bis zum Beginn des überdeckenden Abschnittes 26 am traufseitigen Ende 28 erstreckt. Die Dicke und die Breite des Vorsprungs 14 nehmen zur Mitte der Dacheindeckungsplatte 10 hin zu und zu deren Rändern hin ab. Die übergänge sind schräg und mit gerundeten Kanten ausgeführt, so daß keine Kerbwirkung entstehen kann. Am firstseitigen Ende 24 der Dacheindeckungsplatte 10 sind Löcher 56, 58 vorgesehen.In FIG. 3, the bottom view of the roofing plate 10 shows the shape of the strengthening projection 14, which extends below the central rim 52 from the ridge-side end 24 to the beginning of the overlapping section 26 at the eaves-side end 28. The thickness and the width of the protrusion 14 increase towards the center of the roof covering plate 10 and decrease towards the edges thereof. The transitions are oblique and with rounded edges so that no notch effect can occur. Holes 56, 58 are provided at the ridge-side end 24 of the roof covering plate 10.

In Fig. 4 sind die Einzelteile der Dacheindeckungsplatte 10 in perspektivischer Ansicht vor der Montage dargestellt. Außer der Form der in einer Ebene liegenden rechteckigen Auflagefläche 18 auf der Mittelkrempe 52 und dem innerhalb dieser befindlichen erhöhten Bereich 20 ist in dieser Figur eine an einer Seitenfläche des Horns 38 vorgesehene Stufe 60 zur rastenden Arretierung von Dachzubehör besonders deutlich zu erkennen.In Fig. 4, the individual parts of the roofing plate 10 are shown in a perspective view before assembly. In addition to the shape of the rectangular support surface 18 lying in one plane on the center brim 52 and the raised area 20 located within it, a step 60 provided on a side surface of the horn 38 for latching locking of roof accessories can be seen particularly clearly in this figure.
