Description

Die Erfindung betrifft eine Reinigungs-Dachplatte gemäß den oberbegrifflichen Merkmalen des Anspruches 1.The invention relates to a cleaning roof panel according to the generic features of claim 1.

Eine Reinigungs-Dachplatte zum Sauberhalten der Gebäudedächer, beispielsweise bei Bewuchs- oder Umweltschmutz ist aus der DE-A-44 13 119 bekannt, wobei die Reinigungs-Dachplatte aus plattenförmigem, kupferhaltigem Material durch Stanzen hergestellt ist, so daß in Verbindung mit der Feuchtigkeit eine chemische Reaktion hervorgerufen wird, die einen Bewuchs oder eine Verunreinigung der Gebäudedächer rückgängig machen kann, sowie zukünftig verhindern soll. Eine am äußeren Rand der Metall-Dachplatte eingeprägte Wulst verzögert hierbei das Abfließen der Feuchtigkeit aus Regen, Schnee oder Nebel. Hierdurch wird die Reaktionszeit zum Lösen von Kupferionen aus der Metall-Dachplatte erhöht, wodurch der Bewuchs der Dachplatten durch Moose und Gräser verhindert wird. Weiterhin kann in bevorzugter Ausführung die Reaktionsfläche von Feuchtigkeit und Metall-Dachplatte dadurch erhöht werden, daß in der unteren Hälfte der Metall-Dachplatte Noppen mit Durchtrittslöchern in erhabener Form eingeformt werden, beispielsweise durch Drücken, so daß die Feuchtigkeit auch auf die Unterseite der Metall-Dachplatte gelangen kann und dadurch zumindest eine Verdoppelung der Reaktionsfläche erreicht wird. Durch diese Maßnahmen wird erreicht, daß je nach Größe der Gebäudedachfläche bereits eine Reihe derartiger Metall-Dachplatten ausreichen, um die selbsttätige Reinigungswirkung zu erreichen, insbesondere Moosbewuchs zu unterdrücken.A cleaning roof panel to keep the building roofs clean, for example in the case of fouling or environmental pollution DE-A-44 13 119 known, the cleaning roof panel from plate-shaped, copper-containing material by punching is made so that in connection with moisture chemical reaction that causes fouling or can reverse contamination of the building roofs, as well as prevent in the future. One on the outer edge of the Embossed metal roof plate delays this Drain moisture from rain, snow or fog. This will cause the reaction time to dissolve copper ions the metal roof panel increases, causing the vegetation of the Roof tiles are prevented by moss and grass. Farther can, in a preferred embodiment, the reaction surface of Moisture and metal roof panel can be increased in that the lower half of the metal roof panel with knobs Passage holes are formed in a raised form, for example, by pressing so that the moisture is also on the bottom of the metal roof panel can get through and at least a doubling of the reaction area is achieved. These measures ensure that, depending on the size of the Building roof surface already a number of such metal roof panels are sufficient to the automatic cleaning effect achieve, especially to suppress moss growth.

Aus der DE-A-41 30 365 ist ebenfalls eine Vorrichtung aus Kupfer zum Schutz von Dachbedeckungen und zur Unterdrückung von Moos oder Flechtenbewuchs bekannt, wobei das Regenwasser Bestandteile aus Kupfermitteln lösen soll, um somit einem Bewuchs durch Moose und Flechten entgegenzuwirken. Diese Kupfermittel sind im Sichtbereich der Dachfläche so angebracht, daß das von den Kupfermitteln abfließende Regenwasser eine möglichst große Fläche der Dachabdeckung überfließt. Die Kupfermittel sind hierbei in Form von Firsthauben ausgebildet, bestehend vollständig aus Kupfer oder mit Kupferblech ummantelt oder einem im Bereich des Dachfirstes eingelegten Kupferblech, was jedoch die Ablaufgeschwindigkeit in unerwünschtem Maße erhöht.From DE-A-41 30 365 there is also a device made of copper to protect roof coverings and to suppress moss or lichen growth known, the rainwater components should dissolve from copper agents in order to prevent moss growth and counteract lichen. These copper agents are in the Visible area of the roof surface attached so that the Rainwater flowing out of copper means the largest possible Surface of the roof cover overflows. The copper means are here formed in the form of ridge hoods Made entirely of copper or coated with copper sheet or one copper sheet inserted in the area of the roof ridge, but that the running speed increases to an undesirable extent.

Eine ähnliche Ausführung mit Kupferstreifen wird in der DE-A-41 11 813 beschrieben, wobei Kupfer auch als Lack oder Anstrich aufgebracht werden kann, in dem Pulver oder Granulat gebunden ist. Der Lack oder Anstrich verhindert dabei jedoch weitgehend den Ionenaustausch. Ähnliches gilt für die in der DE-OS 28 40 814 vorgeschlagenen Dachsteine zur Bewuchsverhinderung, wobei Kupfer in das Pfannenmaterial eingemischt oder oberflächlich aufgetragen wird.A similar version with copper strips is used in the DE-A-41 11 813 described, copper also as lacquer or Paint can be applied in the powder or granules is bound. However, the varnish or paint prevents it largely ion exchange. The same applies to those in the DE-OS 28 40 814 proposed roof tiles for Prevention of fouling, with copper in the pan material mixed or applied superficially.

Bei dem vorstehend genannten Stand der Technik mit Anordnung von Kupferblechen im Sichtbereich der Dachfläche ist jedoch nachteilig, daß hierdurch die Gleichmäßigkeit der Dachfläche, zumindest im Neuzustand des Kupferbleches, unterbrochen wird, so daß das gleichmäßige Aussehen der Dachfläche gestört wird, was von manchen Bauherrn oder auch der Denkmalschutzbehörde, insbesondere bei historischen Altbauten, nicht akzeptiert wird. Zudem werden gerade historische Bauten mit roten, unglasierten Flachtonziegeln ("Biberschwänze") eingedeckt, so daß das im Laufe der Zeit oxidierende und damit dunkelbraune Kupferblech eine optische Unterbrechung der gleichmäßig roten Dachfläche bewirken würde.In the above-mentioned prior art with arrangement of However, there is copper sheet in the visible area of the roof surface disadvantageous that the uniformity of the roof surface, at least when the copper sheet is in new condition that the uniform appearance of the roof surface is disturbed, what by some builders or the monument protection authority, especially in the case of historic old buildings. In addition, historical buildings with red, unglazed are currently being used Flat clay bricks ("beaver tails") covered, so that in Over time oxidizing and thus dark brown copper sheet an optical interruption of the evenly red roof surface would cause.

Zudem weisen derartige Metall-Dachziegel oder Kupferbleche einen erhöhten Herstellungsaufwand auf, da im letzteren Falle häufig ein Spengler die fachgerechte Verlegung übernehmen muß, während im ersteren Falle die Metall-Dachplatten aufgrund steigender Rohstoffpreise für Kupfer ebenfalls einen gewissen Kostenaufwand darstellen, zumal die aus Dachziegeln bestehende Unterkonstruktion zur Abstützung ohnehin erforderlich ist. In addition, such metal roof tiles or copper sheets have one increased manufacturing costs, since in the latter case often a plumber must take care of the proper laying while in the former case the metal roof panels due to increasing Raw material prices for copper also have a certain cost represent, especially since the consisting of roof tiles Substructure for support is required anyway.

Das in der DE-A-41 11 813 angesprochene Lackieren bzw. Anstreichen ist ebenfalls herstellungsaufwendig, da für derartige Ziegelmaterialien spezielle Lacke erforderlich sind, die zudem Kupferpulver durch die Einbindung isolieren und damit einen Ionenaustausch verhindern. Zudem wird durch die Lackierung die Plattenoberfläche relativ glatt, so daß die Ablaufgeschwindigkeit steigt und somit die Reaktionszeit bis zur Unwirksamkeit verringert wird, sowie das Aussehen von unglasierten Dachziegeln verändert wird.The painting mentioned in DE-A-41 11 813 or Painting is also expensive to manufacture because for such brick materials require special varnishes, which also isolate copper powder through the integration and thus prevent ion exchange. In addition, the paint job the plate surface relatively smooth, so that the Expiration speed increases and thus the reaction time up to Ineffectiveness is reduced, as well as the appearance of unglazed roof tiles is changed.

Weiterhin ist aus der EP 0 727 542 A1 des Anmelders konkret bekannt, die Oberfläche von Dachplatten beziehungsweise Dachziegeln mit Metallpartikeln, vorzugsweise mit kleingebrochenen Kupferspänen, zu beschichten, indem diese auf den noch ungebrannten Ziegel gestreut und eingewalzt oder mit einem Abzugslineal eingestrichen werden, wobei mindestens ein kleiner Teil des Metallpartikels aus der Oberfläche herausstehen soll.Furthermore, EP 0 727 542 A1 of the applicant is specific known, the surface of roof tiles or tiles with metal particles, preferably with small particles Copper shavings to coat by placing these on the still strewn and rolled in unfired bricks or with a Trigger ruler, at least a small one Part of the metal particle protrudes from the surface should.

Es ist daher Aufgabe der Erfindung eine Dachplatte oder einen Dachziegel zum selbsttätigen Reinigen einer Dachoberfläche zu schaffen, die/der störenden Bewuchs durch Moose oder Flechten unterbindet, welche einerseits ein möglichst gleichmäßiges Aussehen mit üblichen Dachplatten oder Dachziegeln aufweist und zudem gegenüber den bekannten beschichteten Dachplatten und -ziegeln eine vergrößerte aktive Reaktionsfläche im Verhältnis zum Materialeinsatz aufweist.It is therefore an object of the invention a roof panel or a Roof tiles for automatic cleaning of a roof surface create the disturbing vegetation by moss or lichen prevents which on the one hand is as uniform as possible Appearance with usual roof tiles or tiles and also compared to the known coated roof panels and tiles an enlarged active reaction area in proportion for use of materials.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 erfüllt, vorteilhafte Ausbildungen sind in den Unteransprüchen beschrieben.This object is achieved by the features of claim 1 fulfilled, advantageous training are in the dependent claims described.

Der Erfinder hat erkannt, dass diese Methode zur Aufbringung von Metallteilchen gemäß der EP 0 727 542 A1 verbessert werden kann, da, um eine wirkungsvolle Verbindung zwischen den wahllos aufgestreuten Metallteilchen und dem Dachziegelkörper zu erreichen, diese Metallteilchen in den Ziegelkörper eingewalzt oder eingestrichen werden müssen. Hierdurch legen sich diese Teilchen weitestgehend flach und es entsteht relativ zum Materialeinsatz nur eine zu geringe aktive Reaktionsfläche. Eine grundlegende Verbesserung läßt sich dadurch erreichen, dass die Metallteilchen aufrechtstehend in die Dachziegel- oder Dachplattenoberfläche eingedrückt werden.The inventor has recognized that this method of application of metal particles can be improved according to EP 0 727 542 A1 can because there is an effective connection between the indiscriminate scattered metal particles and the roof tile body reach, these metal particles rolled into the brick body or need to be painted. This will put them down Particles largely flat and it is created relative to the material used only too little active reaction area. A fundamental improvement can be achieved in that the metal particles upright in the tile or Roof panel surface are pressed.

Durch die in die Dachplattenoberfläche aufrechtstehend eingesetzten oder eingedrückten Metallteilchen kann die durch Regen, Schneefall, Nebel verursachte Feuchtigkeit mit den Metallteilchen reagieren und hierdurch bei gleichmäßiger Verteilung der Feuchtigkeit über die Gebäudedachfläche Wachstum von Moos- und Pilzbewuchs und Umweltschmutz verhindern. Durch die formschlüssige Verankerung der Metallteilchen, insbesondere von feinen Kupferdrähten oder Kupferstiften, in die Ziegeloberfläche wird eine große aktive Reaktionsfläche gebildet, da sich die bürstenartig eingesetzten Kupferdrähte nach dem Eindrücken in das Plattenmaterial "gamsbartartig" auseinanderspreizen und somit eine besonders große, aktive Reaktionsoberfläche aufweisen. Gegenüber aufgestreuten Metallpartikeln aus kurzgebrochenen Spänen wird zudem durch das im wesentlichen senkrechte Eindrücken eine sichere Verankerung in der Platten- bzw. Ziegeloberfläche erreicht. By standing up in the roof panel surface used or pressed metal particles can by Rain, snow, fog caused moisture with the Metal particles react and thereby more evenly Distribution of moisture over the building roof surface growth prevent moss and fungus growth and environmental pollution. By the positive anchoring of the metal particles, in particular of fine copper wires or copper pins into which Brick surface becomes a large active reaction area formed because the brush-like copper wires after being pressed into the plate material "chamois-like" spread apart and thus a particularly large, active Have reaction surface. Sprinkled opposite Metal particles from broken chips are also removed by the essentially vertical impressions secure anchoring reached in the slab or brick surface.

Diese bürstenartige Reaktionsfläche erhöht dadurch die lange Reaktionszeit bei abfließender Feuchtigkeit, insbesondere in Verbindung mit ebenfalls rasterartig eingedrückten Vertiefungen, so daß eine besonders intensive Reaktion mit den Metallteilchen erreicht wird, wodurch der Bewuchs der Dacheindeckung sicher verhindert wird, auch wenn nur eine oder einige Reihen einer solchen Reinigungs-Dachplatte vorgesehen sind. Zudem weist dieses Eindrücken von feinen Kupferdrähten oder geriffelten Kupferstiften in die weiche Ziegeloberfläche noch vor dem Brennen des Dachziegels eine praktisch unveränderte Farbstruktur des Dachziegels auf, so daß derartige Dachziegel in unglasierter Ausführung auch für die Eindeckung von denkmalgeschützten Gebäuden geeignet sind.This brush-like reaction surface increases the long time Response time when moisture flows out, especially in Connection with depressions also depressed in a grid-like manner, so that a particularly intense reaction with the metal particles is achieved, which ensures the vegetation of the roof covering is prevented, even if only one or a few rows of one such cleaning roof panel are provided. Also points this indentation of fine copper wires or corrugated Copper pins in the soft brick surface before Burning the roof tile has a practically unchanged color structure of the roof tile, so that such roof tiles in unglazed Execution also for the covering of listed buildings Buildings are suitable.

Ein derartiger Dachziegel kann, wie vorstehend beschrieben, durch einfaches Eindrücken von Metallteilchen im wesentlichen senkrecht zur Plattenoberfläche in die noch weiche, ungebrannte Dachplatte hergestellt werden, wobei als Metallteilchen bevorzugt Kupferdrähte oder Kupferstifte bzw. nagelartige Drahtabschnitte oder Blechabschnitte verwendet werden, die relativ preiswert sind. Zudem kann ein derartig hergestellter Dachziegel in üblicher Weise verlegt werden, so daß keine zusätzlichen Spenglerarbeiten oder dergleichen erforderlich sind.Such a roof tile can, as described above, by simply pushing in metal particles perpendicular to the plate surface in the still soft, unfired Roof plate are made, being as metal particles preferably copper wires or copper pins or nail-like Wire sections or sheet metal sections can be used are relatively inexpensive. In addition, a manufactured in this way Roof tiles are laid in the usual way, so that none additional plumbing work or the like is required are.

Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Further advantageous configurations result from the Dependent claims.

Several exemplary embodiments of the cleaning roof panel according to the invention are explained and described in more detail below with reference to the drawing. Here show:

a side view along the cleaning roof panel in the installed state on a roof.

In Fig. 1 ist eine Reinigungs-Dachplatte 1 in der Ausführung als "Biberschwanz" dargestellt, wobei in der in Wasserabflußrichtung unteren Hälfte der Ziegel- bzw. Plattenoberfläche 2 eine Metallteilchen-Bestückung 3 vorgesehen ist. Diese Metallteilchen-Bestückung 3 besteht aus einer Vielzahl von stehend eingesetzten Metallteilchen 4, die bevorzugt aus senkrecht oder auch leicht schräg zur Plattenoberfläche 2 ausgerichteten Kupferdrähten oder Kupferstiften bestehen. Für eine gleichmäßige Rasterung der Metallteilchen 4, können diese Metallteilchen 4 durch Eindrückstempel in die noch weiche, ungebrannte Ziegeloberfläche jeweils einzeln oder bevorzugt jeweils in einer Zeile oder auch alle gleichzeitig an den in Fig. 1 durch ein Kreuz gekennzeichneten Stellen eingedrückt werden.In Fig. 1 is a cleaning roof panel 1 in the execution as "Beaver tail" shown, being in the direction of water drainage lower half of the brick or slab surface 2 a Metal particle assembly 3 is provided. This Metal particle assembly 3 consists of a variety of standing metal particles 4, which are preferably made of perpendicular or slightly oblique to the plate surface 2 aligned copper wires or copper pins. For a uniform grid of the metal particles 4, they can Metal particles 4 by stamping into the still soft, unfired brick surface individually or preferred each in one line or all at the same time in Fig. 1 depressed by a cross marked become.

Es sei darauf hingewiesen, daß anstatt der Kupferdrähte als Metallteilchen 4 auch dünne Metallstifte oder Blechabschnitte oder auch Röhrchen mit Durchbrüchen, insbesondere mit geriffelter oder profilierter Oberfläche verwendet werden können, wobei jedoch die Länge der Metallteilchen 4 so gewählt ist, daß zumindest das obere Drittel der stehend eingedrückten Metallteilchen 4 aus der Plattenoberfläche 2 hervorsteht, um hier eine große aktive Reaktionsfläche für die auf der Reinigungs-Dachplatte 1 abfließende Feuchtigkeit zu bieten.It should be noted that instead of the copper wires as Metal particles 4 also thin metal pins or sheet metal sections or also tubes with openings, especially with corrugated or profiled surface can be used can, however, the length of the metal particles 4 selected is that at least the top third of the standing indented Metal particles 4 protrudes from the plate surface 2 here is a large active reaction area for those on the Cleaning roof panel 1 to offer drained moisture.

In Fig. 2 ist ein Querschnitt gemäß der Schnittlinie A-A dargestellt, woraus die Struktur an der Oberfläche 2 der Reinigungs-Dachplatte 1 mit einer Halterungsnase 5 an der Unterseite ersichtlich ist. Zur Erhöhung der aktiven Reaktionsfläche mit Feuchtigkeit können in dem in Abflußrichtung unteren Bereich Vertiefungen 6 in Form von Kalotten (in Fig. 1 als Kreise angedeutet) in den Plattenrohling eingedrückt sein. Die von der Reinigungs-Dachplatte 1 abfließende Feuchtigkeit, insbes. Regenwasser überstreicht zunächst die Oberfläche 2, wobei ein Teil der abfließenden Feuchtigkeit in die Vertiefungen 6 gelangt und dort mit den Metallteilchen 4 in intensiven Kontakt tritt, bevor sie weiter abfließt (vgl. auch Fig. 3). Entlang diesem Abflußweg ist hierbei die Feuchtigkeit ständig in Kontakt mit den geringfügig aus den Oberflächen der Vertiefungen 6 hervorstehenden Metallteilchen 4, so daß eine besonders große Reinigungseffektivität erreicht wird. Wie ersichtlich, sind die Metallteilchen 4 dabei etwa zu einem Drittel ihrer Länge in die Plattenmasse eingedrückt, so daß sich eine sichere Verankerung ergibt.In Fig. 2 is a cross section along the section line A-A shown, from which the structure on the surface 2 of the Cleaning roof panel 1 with a mounting tab 5 on the Underside is visible. To increase active Reaction surface with moisture can in the downflow direction depressions 6 in the form of domes (in FIG. 1 indicated as circles) can be pressed into the blank. The moisture flowing away from the cleaning roof panel 1, rainwater first sweeps over surface 2, some of the moisture draining into the wells 6 arrives and there with the metal particles 4 in intensive Contact occurs before it continues to flow away (see also Fig. 3). The moisture is constantly in along this drainage path Contact with the slightly from the surfaces of the wells 6 protruding metal particles 4, so that a particularly large Cleaning effectiveness is achieved. As can be seen, they are Metal particles 4 about a third of their length in the Panel mass pressed in, so that there is a secure anchorage results.

In Fig. 3 ist eine Seitenansicht entlang einer derartigen Reinigungs-Dachplatten-Eindeckung gezeigt, wobei der Wasserabfluß jeweils über den unteren Bereich der Oberseite 2 und die dort eingesetzte Metallteilchen-Bestückung 3, sowie durch die Vertiefungen 6 mit einer gewissen Speicherwirkung erfolgt, wobei durch diese zusätzliche Wasserverweildauer eine intensive Reaktion mit den eingesetzten Metallteilchen 4 möglich ist, die aus der Oberfläche ähnlich wie bei einer Bürste hervorstehen.3 is a side view along such Cleaning roof tile covering shown, the Water drainage over the lower area of the top 2 and the metal particle assembly 3 used there, and through the recesses 6 with a certain storage effect takes place, with this additional water retention time intensive reaction with the metal particles 4 possible which is from the surface similar to a brush protrude.

Die vorgeschlagene rasterartige Metallteilchen-Bestückung 3 wird durch Eindrücken von Metallteilchen 4, insbesondere von Kupferdrähten oder geriffelten Kupferstiften, in die noch ungebrannte Ziegel- bzw. Plattenoberfläche 2 und anschließendem, üblichem Brennen des Dachziegels 1 erreicht. Um eine sichere Verankerung der Metallteilchen 4 in der Oberfläche 2 bzw. den darin ausgebildeten Vertiefungen 6 zu erreichen, können die Metallteilchen 4 vor dem Brennen in die noch weiche Ziegelfläche etwa bis zur halben Dicke der Reinigungs-Dachplatte 1 ggf. mit entsprechenden Vorlochungen eingedrückt werden. Durch dieses Herstellungsverfahren wird die Dachziegel-Herstellung kaum verteuert oder aufwendiger, so daß die Fabrikation auf üblichen Dachziegel-Herstellanlagen mit zusätzlicher Metallteilchen-Eindrückung in einfacher Weise realisiert werden kann.The proposed grid-like metal particle assembly 3 is by pressing metal particles 4, in particular Copper wires or fluted copper pins in the still unbaked brick or plate surface 2 and subsequent, usual burning of the roof tile 1 reached. To be safe Anchoring the metal particles 4 in the surface 2 or to achieve recesses 6 formed therein, the Metal particles 4 before burning in the still soft brick surface up to half the thickness of the cleaning roof panel 1, if necessary appropriate pre-punched holes are pressed. Because of this Roof tile production is hardly a manufacturing process more expensive or more elaborate, so that the production on usual Roof tile manufacturing plants with additional metal particle indentation can be realized in a simple manner.

Unter Reinigungs-Dachplatte sind hierbei auch Betonziegel oder Dachplatten aus ähnlichen Materialien, wie z. B. die sog. "Frankfurter Pfanne" zu verstehen, wobei aufgrund der dort vorgesehenen gewölbten Querschnittsform und geringer Überdeckung eine Metallteilchen-Eindrückung auch auf der gesamten PlattenOberseite vorgesehen sein kann. Im Falle von Betondachplatten erfolgt die Eindrückung im unausgehärteten Zustand des vorgeformten Dachplatten-Rohlings. Die Metallteilchen-Bestückung 3 ist dabei auch in Schieferplatten und dickwandigen Dachpappen anwendbar, wobei die Metallteilchen 4 ähnlich wie ein Niet auch in vorgestanzte Lochungen von der Rückseite her mit einem Dichtungsbund eingesetzt werden können. Im Falle von Bitumen-Dachpappe als Reinigungs-Dachplatte ergibt sich durch die Eigenelastizität des Materials eine sichere Abdichtung sogar ohne zusätzliche Dichtungsmaßnahmen.Under the cleaning roof plate there are also concrete tiles or Roof panels made of similar materials, such as. B. the so-called "Frankfurter Pfanne" to understand, being due to there provided arched cross-sectional shape and low coverage metal particle indentation also on the entire top of the panel can be provided. In the case of concrete roof tiles the indentation takes place in the uncured state of the preformed blank roof tiles. The metal particle assembly 3 is also in slate slabs and thick-walled roofing felt applicable, the metal particles 4 similar to a rivet in pre-punched holes from the back with a Seal collar can be used. In the case of bitumen roofing felt as a cleaning roof panel results from the The material's inherent elasticity even ensures a secure seal without additional sealing measures.
