The side edges (5a,5b) of the shield may be built with a mount (6) which crosses over in the plate base. The mount may be rounded and built as a prop for the shield. The metal roof plate may be embossed with copper plating.

Description

Die Erfindung betrifft eine Metall-Dachplatte zum Eindecken von Gebäudedächern, wobei die Metall-Dachplatte zwischen aufeinanderfolgenden Plattenreihen der Dacheindeckung eingefügt und mit einer Halterung gegen Abrutschen befestigt ist.The invention relates to a metal roof panel for roofing building roofs, the metal roof panel being inserted between successive rows of panels of the roof covering and fastened with a holder to prevent it from slipping.

Eine derartige Metall-Dachplatte ist aus der DE-A-44 13 119 bekannt. Diese Metall-Dachplatte dient insbesondere zur Reinigung von Gebäudedächern und der Bewuchsverhinderung durch Moos. Hierzu ist die Metall-Dachplatte bevorzugt aus Kupferblech ausgebildet, wobei zur Steigerung der Reinigungswirkung aus der Plattengrundfläche bzw. Reaktionsfläche Noppen herausgedrückt sein können, so daß ein schnelles Ablaufen der Feuchtigkeit verhindert wird, sondern die Reaktionszeit von Feuchtigkeit mit den Metallionen der Metall-Dachplatte vergrößert wird. Diese Metall-Dachplatte zum Einfügen zwischen aufeinanderfolgenden Plattenreihen der Dacheindeckung hat sich auch deshalb bewährt, da die Befestigung der Metall-Dachplatte durch einfache Weise durch Einstecken und Fixierung mittels eines nasenförmigen Halterungsprofiles erreicht werden kann.Such a metal roof panel is known from DE-A-44 13 119. This metal roof panel is used in particular for cleaning the roofs of buildings and preventing fouling by moss. For this purpose, the metal roof plate is preferably formed from copper sheet, with nubs being able to be pushed out of the plate base or reaction surface to increase the cleaning effect, so that rapid drainage of the moisture is prevented, but rather the reaction time of moisture with the metal ions of the metal roof plate is increased becomes. This metal roof panel for insertion between successive rows of panels of the roof covering has also proven itself because the fastening of the metal roof panel can be achieved in a simple manner by inserting and fixing by means of a nose-shaped mounting profile.

In schneereichen Gegenden werden gegen Abrutschen von Dachlawinen von den Baubehörden häufig Schneefangelemente vorgeschrieben, die im allgemeinen den nachfolgend beschriebenen Aufbau aufweisen. Hierbei werden gesonderte Schneefanggitter an entsprechend befestigten Haken eingehängt, wobei die Haken zur breitflächigen Abstützung ebenfalls an ihrer Unterseite plattenförmig ausgebildet sein können. Die Montage derartiger Schneefanggitter ist jedoch sehr aufwendig, da die einzelnen Gitterelmente in der Dachbreite abgelängt werden müssen. Demgemäß müssen auch die Abstützpunkte gewählt werden. Eine Anbringung derartiger Schneefanggitter über Gauben oder Kamineinfassungen ist kaum möglich, ohne die Dachfläche optisch zu verunstalten.In snowy areas, the building authorities often prescribe snow guard elements to prevent roof avalanches from slipping, which generally have the structure described below. In this case, separate snow guard grids are hung on appropriately fastened hooks, the hooks for wide-area support also being able to be plate-shaped on their underside. However, the installation of such snow guard grilles is very complex since the individual grid elements have to be cut to length in the roof width. The support points must also be selected accordingly. Attaching such snow guard grilles over dormers or Chimney edging is hardly possible without visually defacing the roof surface.

Demgemäß liegt der Erfindung die Aufgabe zugrunde, eine Metall-Dachplatte zum Eindecken von Gebäudedächern zu schaffen, die einfach zu montieren und herzustellen, sowie ein wirksames und optisches ansprechendes Schneefangelement bildet.Accordingly, the invention has for its object to provide a metal roof panel for covering building roofs, which is easy to assemble and manufacture, and forms an effective and visually appealing snow guard element.

Diese Aufgabe wird gelöst durch eine Metall-Dachplatte mit den Merkmalen des Anspruches 1.This object is achieved by a metal roof panel with the features of claim 1.

Durch die Bildung des Schneefangelementes aus wenigstens einem aufrechtstehenden Schild, das aus der Plattengrundfläche herausgebogen (ausgeklinkt) ist, wird eine einfache Herstellung erreicht. Zudem kann diese Metall-Dachplatte als Schneefangelement ohne weitere Halterungen einfach zwischen aufeinanderfolgenden Plattenreihen verlegt werden. Zusätzliche Schraub- oder Nagelarbeiten werden hierdurch vermieden. Durch das Herausbiegen des Schildes aus der Plattengrundfläche wird zudem ein gleichmäßiges Erscheinungsbild geboten, insbesondere wenn die Metall-Dachplatte aus Kupferblech geprägt ist und somit in Anpassung an übliche Dachfarben im Laufe der Zeit nachdunkelt. Hierdurch wird eine optische besonders ansprechende Dacheindeckung erreicht.The formation of the snow guard element from at least one upright shield, which is bent out from the base of the plate, enables simple manufacture. In addition, this metal roof panel as a snow guard element can be easily installed between successive rows of panels without additional brackets. This avoids additional screwing or nailing work. By bending the sign out of the base of the panel, a uniform appearance is also offered, especially if the metal roof panel is stamped from copper sheet and thus darkens over time in line with the usual roof colors. As a result, a particularly attractive roof covering is achieved.

Von besonderem Vorteil ist zudem die Ausbildung aus Kupferblech, da Kupfer einer der besten Wärmeleiter ist, wodurch bei Sonneneinstrahlung im Winter ein gleichmäßiges Abtauen des Schnees auf den Gebäudedach erreicht wird.The formation of copper sheet is also of particular advantage, since copper is one of the best heat conductors, which ensures that snow is thawed evenly on the roof of the building in winter.

Von weiterem Vorteil ist hierbei die Perforierung des Schildes, da hierdurch zusätzlich Tauwasser in Abflußrichtung austreten kann und somit eine rasche Schnee-Abtauung erreicht werden kann. Zudem tritt hierbei der abtauende Schnee in intensive Reaktion mit der Metall-Dachplatte, so daß gemäß der DE-A-44 13 119 eine intensive Reinigungswirkung erzielt wird. Weiterhin ist von Vorteil, wenn die Seitenkanten des Schildes mit je einem abgerundeten Steg in die Plattengrundfläche übergehen, wodurch eine besonders hohe Formstabilität des aufrechtstehenden Schildes erreicht wird. Somit sind auch hohe Schneelasten durch die Metall-Dachplatte zu bewältigen. Insbesondere bei sehr steilen Dächern wird hierbei der Kraftfluß zwischen dem in montierter Stellung aufrechtstehenden Schneefang-Schild und der Plattengrundfläche an die jeweils herrschende Belastung angepaßt, so daß eine hohe Formstabilität erreicht wird.A further advantage here is the perforation of the shield, since this can cause additional condensation to escape in the direction of the drain and thus rapid snow defrosting can be achieved. In addition, the thawing snow comes into intensive reaction with the metal roof plate, so that an intensive cleaning effect is achieved according to DE-A-44 13 119. It is also advantageous if the side edges of the shield merge into the base surface of the plate, each with a rounded web, whereby a particularly high dimensional stability of the upright shield is achieved. This means that even heavy snow loads can be managed through the metal roof panel. Particularly in the case of very steep roofs, the flow of force between the snow guard shield which is upright in the installed position and the base of the plate is adapted to the prevailing load, so that a high degree of dimensional stability is achieved.

Weitere vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Further advantageous embodiments are the subject of the dependent claims.

Nachfolgend wird ein Ausführungsbeispiel der Metall-Dachplatte anhand der Zeichnungen näher beschrieben und erläutert. Hierbei zeigen:

Fig. 2
eine Draufsicht auf die Metall-Dachplatte gemäß Fig. 1.
An exemplary embodiment of the metal roof panel is described and explained in more detail below with the aid of the drawings. Here show:
Fig. 1
a longitudinal sectional view through a roof covering; and
Fig. 2
2 shows a plan view of the metal roof panel according to FIG. 1.

In Fig. 1 ist eine Längsschnittdarstellung durch eine Dacheindeckung 2 gezeigt, die aus einer Vielzahl von aufeinanderfolgenden Plattenreihen 2a, 2b, 2c usw. besteht. Hier ist zwischen die Plattenreihe 2b und 2c eine Metall-Dachplatte 1 eingefügt und mittels einer nasenförmigen Halterung 3 gegen Abrutschen gesichert. Die Plattengrundfläche 4 der Metall-Dachplatte 1 entspricht dabei im wesentlichen der Form der verwendeten Dachziegel, beispielsweise wie hier dargestellt, einer sogenannten Biberschwanz-Dachplatte (vgl. auch Fig. 2).In Fig. 1, a longitudinal sectional view through a roof covering 2 is shown, which consists of a plurality of successive rows of plates 2a, 2b, 2c, etc. Here, a metal roof panel 1 is inserted between the row of panels 2b and 2c and secured against slipping by means of a nose-shaped holder 3. The plate base area 4 of the metal roof plate 1 essentially corresponds to the shape of the roof tiles used, for example, as shown here, a so-called beaver tail roof plate (cf. also FIG. 2).

Aus der Plattengrundfläche 4 der Metall-Dachplatte 1 ist hierbei nach einem Trennschnitt entlang der gebogenen Schnittlinie 8 (vgl. Fig. 2) der in Ablaufrichtung untere Bereich der Metall-Dachplatte 1 nach oben gebogen, so daß ein aufrechtstehendes Schild 5 als Schneefangelement entsteht. Die Höhe H des Schildes 5 entspricht hierbei etwa der halben Plattenlänge L. Es sei jedoch darauf hingewiesen, daß je nach erwartetem Schneeanfall die Höhe H des Schildes 5 auch niedriger gewählt werden kann, indem die Trenn- oder Schnittlinie 8 weiter zum unteren Ende hin angeordnet wird. Durch das Herausbiegen des Schildes 5 aus der Plattengrundfläche 4 um eine Biegelinie 9 im Bereich des unteren Endes der Metall-Dachplatte entsteht ein Durchbruch 7, so daß bei einer Draufsicht im eingesetzten Zustand der Metall-Dachplatte 1 die darunterliegende Plattenreihe 2b im Bereich dieses Durchbruches 7 sichtbar ist (vgl. Fig. 2).From the plate base 4 of the metal roof plate 1, the lower region of the metal roof plate 1 in the downward direction is bent upwards after a separating cut along the curved cutting line 8 (see FIG. 2), so that an upright shield 5 is created as a snow guard element. The height H of the plate 5 corresponds approximately to half the plate length L. However, it should be noted that depending on the expected Snowfall, the height H of the shield 5 can also be selected to be lower by arranging the dividing or cutting line 8 further towards the lower end. By bending the shield 5 out of the plate base 4 around a bending line 9 in the area of the lower end of the metal roof plate, a breakthrough 7 is created, so that when the metal roof plate 1 is in the plan view, the underlying row of plates 2b in the area of this hole 7 is visible (see FIG. 2).

Das Herausbiegen des aufrechtstehenden Schildes 5 aus der Plattengrundfläche 4 erfolgt hierbei vorzugsweise durch ein Präge-Werkzeug, so daß die Übergänge des Schildes 5 zu der Plattengrundfläche 4 mitgestaltet werden können. Insbesondere wird hierbei im Bereich der Seitenkanten 5a und 5b des Schildes 5 ein abgerundeter Übergang in Form von je einem Steg 6 mitausgebildet, der zur Abstützung des Schildes 5 und damit zur Erhöhung der Formstabilität der Metall-Dachplatte 1 dient.The upright shield 5 is preferably bent out of the plate base 4 by an embossing tool, so that the transitions of the shield 5 to the plate base 4 can be shaped. In particular, in the area of the side edges 5a and 5b of the shield 5, a rounded transition in the form of a web 6 is also formed, which serves to support the shield 5 and thus to increase the dimensional stability of the metal roof panel 1.

Die hier dargestellte Dachneigung der Dacheindeckung 2 beträgt ca. 25°. Demgemäß ist das Schild 5 um etwa 65° aus der Plattengrundfläche 4 um die Biegelinie 9 herausgebogen. Bei steilerer Dachneigung z. B. 45° müßte somit das Schild zur Erreichung einer aufrechtstehenden Position nur um ca. 45° aus der Plattengrundfläche herausgebogen werden. Dabei können bei der Präge-Bearbeitung der Metall-Dachplatte 1 die beiden seitlichen Stege 6 aufgrund des geringeren Biegewinkels großflächiger ausgebildet sein, so daß sich hierdurch eine Erhöhung der Stabilität des Schildes 5 ergibt, wie dies aufgrund der steileren Dachneigung dann auch erforderlich wäre. Durch diese Gestaltung ergibt sich in Ablaufrichtung eine Art Tasche, die den Schnee sicher auffängt.The roof pitch of the roof covering 2 shown here is approximately 25 °. Accordingly, the shield 5 is bent out about 65 ° from the plate base 4 around the bending line 9. With steeper roof pitch z. B. 45 °, the sign would have to be bent to achieve an upright position only by about 45 ° from the base of the plate. In this case, the two lateral webs 6 can be formed over a larger area due to the lower bending angle during the stamping processing of the metal roof panel 1, so that this results in an increase in the stability of the shield 5, as would then also be necessary due to the steeper roof pitch. This design results in a kind of pocket in the direction of the drain that safely catches the snow.

Es sei darauf hingewiesen, daß bei entsprechend langen Metall-Dachplatten 1 in Abflußrichtung auch mehrere derartiger Schneefangelemente übereinander angeordnet sein können oder bei entsprechend größerer Breite der Metall-Dachplatte 1 auch mehrere derartiger aufrechtstehender Schilde 5 nebeneinander aus der Plattengrundfläche 4 herausgebogen sein können. Dies ist durch entsprechende Werkzeuggestaltung ohne weiteres möglich.It should be noted that with correspondingly long metal roof panels 1, several such snow guard elements can also be arranged one above the other in the outflow direction, or also with a correspondingly larger width of the metal roof panel 1 several such upright shields 5 can be bent out of the plate base 4 side by side. This is easily possible through appropriate tool design.

Bei der Präge-Bearbeitung wird zudem die Plattengrundfläche 4 im Bereich des hochzubiegenden Schildes 5 bevorzugt perforiert, beispielsweise durch herausgedrückte Noppen, wie dies in der DE-A-44 13 119 beschrieben ist. Hierdurch wird zum einen ein verbessertes Ablaufen von abtauendem Schnee erreicht, da der aufliegende Schnee durch die in Fig. 2 mittels Kreuzen angedeuteten Perforationen im aufrechtstehenden Schild 5 ablaufen kann. Hierdurch wird zudem eine intensive Reinigungswirkung durch Aufnahme von Metallionen erreicht, so daß zugleich eine Reinigungswirkung für die Dacheindeckung 2 erzielt wird.In the case of embossing processing, the plate base area 4 is also preferably perforated in the region of the shield 5 to be bent up, for example by pushing out knobs, as is described in DE-A-44 13 119. In this way, on the one hand, an improved drainage of thawing snow is achieved, since the snow lying on it can run through the perforations indicated in FIG. 2 by means of crosses in the upright shield 5. This also achieves an intensive cleaning effect by absorbing metal ions, so that a cleaning effect for the roof covering 2 is achieved at the same time.

In Fig. 2 ist eine Draufsicht auf die Metall-Dachplatte 1 gemäß Fig. 1 dargestellt. Hieraus ist die aufrechtstehende Position des Schildes 5 und der Übergang der Seitenkanten 5a und 5b in die seitlichen Abstützstege 6 ersichtlich. Das perforierte Schild 5, wie dies mit Kreuzen angedeutet ist, wird hierbei um die Biegelinie 9 je nach Dachneigung um einen spitzen Winkel aus der Plattengrundfläche 4 nach oben gebogen, nachdem in der Plattengrundfläche eine Trenn- oder Schnittlinie 8, bevorzugt zusammen mit der Präge-Bearbeitung eingebracht wird. Bei der Präge- oder Stanzbearbeitung der Metall-Dachplatte wird zudem ein Mittelsteg 11 und eine umlaufende Wulst 10 mitausgebildet, um die Formstabilität der Metall-Dachplatte 1 zu gewährleisten. Zudem kann gleichzeitig das nasenförmige Halterungsprofil 3 mithergestellt werden. Die Trenn- oder Schnittlinie 8 ist hierbei bevorzugt gebogen ausgebildet, um hier einen abgerundeten oder "weichen" Übergang zu den seitlichen Stegen 6 und zu dem aufrechtstehenden Schild 5 zu gewährleisten. Zudem wird hierdurch die Verletzungsgefahr bei Verlegung der Metall-Dachplatte als Schneefangelement verringert. Die Biegelinie 9 am nach unten weisenden Ende der Metall-Dachplatte 1 ist hierbei an die jeweils gewählte Dachziegel-Form angepaßt. Bei Wahl von Biberschwanz-Dachziegeln ist die Biegelinie 9 ähnlich dem hier nach links weisenden Abschlußende der Metall-Dachplatte 1 gewölbt, während bei Biberschwanz-Dachziegeln mit gerader Abschlußkante die Biegelinie 9 im wesentlichen senkrecht zur Längserstreckung der Metall-Dachplatte 1 verläuft. Die Biegelinie 9 wird entsprechend der jeweiligen Materialstärke des Kupferbleches und des jeweiligen Biegewinkels in Anpassung an die gewünschte Dachneigung gewählt. Bei üblichen Dachneigungen von 25° bis 40° beträgt somit der Biegewinkel des Schildes 5 ca. 70° bis 50°. Wenn die Höhe H des Schildes 5 ähnlich wie in Fig. 1 relativ hoch gewählt ist, kann die Biegelinie 9 mit einem relativ großen Radius 9' ausgebildet werden, zum einen um die Biegearbeit zu erleichtern, zum andern um eine zusätzliche Abstützung des Schildes 5 zu erreichen.FIG. 2 shows a top view of the metal roof panel 1 according to FIG. 1. This shows the upright position of the shield 5 and the transition of the side edges 5a and 5b into the lateral support webs 6. The perforated shield 5, as indicated by crosses, is bent upwards around the bending line 9 depending on the roof pitch by an acute angle from the plate base area 4 after a dividing or cutting line 8, preferably together with the embossing line, has been formed in the plate base area. Processing is brought. When embossing or punching the metal roof panel, a central web 11 and a circumferential bead 10 are also formed in order to ensure the dimensional stability of the metal roof panel 1. In addition, the nose-shaped mounting profile 3 can be produced at the same time. The dividing or cutting line 8 is preferably curved to ensure a rounded or "soft" transition to the lateral webs 6 and to the upright shield 5. This also reduces the risk of injury when the metal roof panel is installed as a snow guard element. The bending line 9 at the downward-facing end of the metal roof panel 1 is adapted to the shape of the tile selected. If you choose Beaver-tail roof tiles, the bending line 9 is curved similar to the end of the metal roof plate 1 pointing to the left here, while in the case of beaver-tail roof tiles with a straight end edge, the bending line 9 runs essentially perpendicular to the longitudinal extent of the metal roof plate 1. The bending line 9 is selected according to the respective material thickness of the copper sheet and the respective bending angle in adaptation to the desired roof pitch. With usual roof pitches of 25 ° to 40 °, the bending angle of the plate 5 is approximately 70 ° to 50 °. If the height H of the shield 5 is chosen to be relatively high, as in FIG. 1, the bending line 9 can be formed with a relatively large radius 9 ', on the one hand to facilitate the bending work and on the other hand to provide additional support for the shield 5 to reach.

Insgesamt ergibt sich somit eine in einem einzigen oder wenigen Arbeitsgängen herzustellende, einfache Metall-Dachplatte, die die Funktion eines Schneefangelementes besonders wirksam erfüllt. Diese Metall-Dachplatte 1 mit integrierter Schneefangfunktion ist dabei besonders einfach zu verlegen. Dabei können auch im Gegensatz zu den üblichen Schneefanggittern einzelne Metall-Dachplatten punktuell verlegt werden, beispielsweise nur zwei oder drei derartiger Metall-Dachplatten oberhalb von Kamineinfassungen oder Dachgauben. Bei besonders hohem Schneefall kann natürlich andererseits auch die Metall-Dachplatte an zwei oder drei aufeinanderfolgenden Plattenreihen versetzt angeordnet werden.Overall, this results in a simple metal roof panel that can be produced in a single or a few work steps and that fulfills the function of a snow guard element particularly effectively. This metal roof panel 1 with integrated snow guard function is particularly easy to install. In contrast to the usual snow guard grilles, individual metal roof panels can also be installed selectively, for example only two or three such metal roof panels above chimney surrounds or dormer windows. In the case of particularly heavy snowfall, on the other hand, the metal roof panel can of course also be staggered on two or three successive rows of panels.

Schließlich sei darauf hingewiesen, daß unter dem Begriff aufrechtstehenden Schild auch Abweichungen von der Vertikalen verstanden werden, also beispielsweise die in Fig. 1 gezeigte Metall-Dachplatte auch bei anderen Dachneigungen verlegt werden kann, wobei dann das Schild 5 geringfügig außerhalb der Vertikalen ausgerichtet ist. Dies ist jedoch für die Schneefangfunktion nicht einschränkend. Somit kann eine Metall-Dachplatte, bei der das Schild um ca. 60° aus der Plattengrundfläche 4 nach oben herausgebogen ist, für die gebräuchlichen Dacheindeckungen mit Neigungswinkeln von 25° bis 40° ohne weiteres verwendet werden.Finally, it should be pointed out that the term upright sign also means deviations from the vertical, that is to say, for example, the metal roof plate shown in FIG. 1 can also be installed with other roof inclinations, the sign 5 then being oriented slightly outside the vertical. However, this is not restrictive for the snow guard function. Thus, a metal roof panel, in which the sign is bent upwards out of the base surface 4 by approximately 60 °, for the common roof coverings with angles of inclination of 25 ° to 40 ° can be used without further ado.
