Description

Die vorliegende Erfindung betrifft ein Metalldach für die Bedachung von Gebäuden jeglicher Art, mit wenigstens einem Metallelement, das eine Außenschale des Metalldachs bildet und wenigstens eine Metallschicht aufweist.The present invention relates to a metal roof for the Roofing of buildings of any kind, with at least one Metal element that forms an outer shell of the metal roof and has at least one metal layer.

Seit vielen Jahren ist es bekannt, Metallelemente, insbesondere profilierte Metallelemente, für die Dachabdeckung von Bauten, insbesondere Industriebauten zu verwenden. Das Einsetzen von Metalldächern findet zunehmend größere Verbreitung und die Nachfrage danach steigt ständig. Dabei werden auch traditionelle Bauweisen, wie beispielsweise Ziegeldächer, zunehmend durch Metalldächer ersetzt.For many years it has been known to use metal elements, in particular profiled metal elements, for the roof covering of buildings, especially industrial buildings. The The use of metal roofs is becoming increasingly widespread and the demand for it is constantly increasing. Here are also traditional construction methods, such as Tile roofs, increasingly replaced by metal roofs.

Herkömmliche Metalldächer, insbesondere wenn sie als Flachdächer ausgebildet sind, haben jedoch einige Nachteile. Der Hauptnachteil ist, daß sie nur regensicher und nicht vollständig wasserdicht sind. Die mangelnde Wasserdichtigkeit derartiger Metalldächer hat einen entsprechend negativen Einfluß auf die gesamte Bausubstanz. Ausbesserungen gelingen nicht oder nur unter hohem Aufwand nur unzureichend, so daß hohe Erneuerungskosten anfallen.Conventional metal roofs, especially when used as flat roofs are trained, but have some disadvantages. Of the The main disadvantage is that they are only rainproof and not complete are waterproof. The lack of water resistance such metal roofs has a correspondingly negative Influence on the whole structure. Repairs succeed not or only insufficiently at great expense, so that there are high renewal costs.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Metalldach der eingangs erwähnten Art derart zu verbessern, daß dieses auch über einen sehr langen Zeitraum wasserdicht ist.The present invention is therefore based on the object a metal roof of the type mentioned at the beginning improve this even over a very long period of time is waterproof.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das wenigstens eine Metallelement an der Außenseite (Witterungsseite) eine Beschichtung aufweist, und daß Fugen zwischen zwei Metallelementen bzw. den Metallelementen und Dachauf- bzw. -einbauten mit einer Abdichtungsbahn überdeckt sind.According to the invention this object is achieved in that the at least one metal element on the outside (weather side) has a coating, and that joints between two metal elements or the metal elements and Roof structures or internals covered with a waterproofing membrane are.

Dadurch wird erreicht, daß eine komplett verschlossene Außenhaut des Metalldaches erzielt wird und keinerlei Wasser mehr von außen eindringen kann.This ensures that a completely closed outer skin of the metal roof and no water can penetrate more from the outside.

Besondere Vorteile ergeben sich hier bei der Ausbildung einer Stoßfuge zwischen zwei Metallelementen, da ein sicherer Verschluß der Fuge gegenüber der Witterungsseite erfolgt. Damit können die Metallelemente stumpf aneinanderstoßen und werden die temperaturabhängigen Dehnungen bzw. Verkürzungen der Metallelemente, wobei letztere zur Vergrößerung von Stoßfugen führen, sicher abgedeckt und abgedichtet.There are particular advantages here when training a Butt joint between two metal elements, as a more secure The joint is sealed from the weather side. So that the metal elements can butt and the temperature-dependent strains or reductions of the metal elements, the latter for enlarging Guide butt joints, securely covered and sealed.

Vorteilhafterweise ist die Beschichtung des Metallelements als eine kaschierte Abdichtungsbahn ausgebildet, wodurch sich eine dauerhafte Wasserabdichtung ergibt. Eine derartige Abdichtungsbahn ist auch gegenüber Umwelteinflüssen, wie saurem Regen etc. beständig.The coating of the metal element is advantageous formed as a laminated waterproofing membrane, whereby there is permanent waterproofing. Such Waterproofing membrane is also exposed to environmental influences, such as resistant to acid rain etc.

Durch die Kaschierung ergibt sich ein sog. Verbundblech, das sich in hervorragender Weise als Außenhaut des Daches eignet. The lamination results in a so-called composite sheet, which is excellent as the outer skin of the roof is suitable.

Vorteilhafterweise ist zwischen der Folienkaschierung und dem Metallelement eine Korrosionsschutzschicht angeordnet. Diese dient zur Erhöhung des Korrosionsschutzes des Metallelements und erhöht somit insgesamt die einwandfreie Funktion und lange Lebensdauer des Metalldaches.It is advantageous between the film lamination and a corrosion protection layer is arranged on the metal element. This serves to increase the corrosion protection of the metal element and thus overall increases the perfect function and long service life of the metal roof.

Weiterhin ist vorteilhafterweise an der Innenseite des Metallelements eine wasserbalancierende Kaschierung vorgesehen. Mit Hilfe dieser wasserbalancierenden Kaschierung ist es möglich, im Innenraum des Gebäudes, der von dem Metalldach abgedeckt wird, entstehende Kondensationsfeuchte aufzufangen, und damit eine Beeinträchtigung des Gebäudes wie beispielsweise ein Feuchteeindringen in die Wände und gesundheitsgefährdenden Schimmelpilzbefall, zu verhindern.It is also advantageously on the inside of the metal element water-balancing lamination is provided. With the help of this water-balancing lamination it is possible in the interior of the building by the metal roof is covered to collect the resulting condensation moisture, and thus an impairment of the building like For example, moisture penetration into the walls and harmful to health To prevent mold infestation.

Weiterhin kann ebenfalls an der Innenseite zwischen dem Metallelement und der wasserbalancierenden Kaschierung eine Korrosionsschutzschicht angeordnet sein.Furthermore, can also be on the inside between the metal element and the water-balancing lamination Corrosion protection layer may be arranged.

Die Korrosionsschutzschichten sind beispielsweise in Form von Zinkauflagen ausgebildet. Zusätzlich kann eine organische Schutzlackschicht an der Unterseite der Zinkauflage vorgesehen sein.The corrosion protection layers are in shape, for example trained by zinc coatings. In addition, an organic Protective lacquer layer on the underside of the zinc coating be provided.

Vorteilhafterweise wird die Abdichtungsbahn mittels Verklebung aufgebracht, wobei die Kaschierung aus Kunststoffmaterial gebildet ist. Bei Thermoplasten kann auch eine Verschweißung erfolgen, die vorteilhafterweise mittels Warmgas oder Quellschweißmittel (Lösungsmittel) durchgeführt wird. The sealing membrane is advantageously bonded applied, the lamination made of plastic material is formed. Thermoplastics can also be welded take place, which advantageously by means of hot gas or welding solvent (solvent) is carried out.

Insbesondere bei Elastomeren erfolgt die Anbringung durch Verkleben.In the case of elastomers in particular, they are attached by Gluing.

Geeignete Materialien für die Abdichtungsbahn sind hierbei hochpolymere Bahnen, insbesondere Thermoplaste wie EVA, PVC, Polyolefine, thermoplastische Elastomere und Elastomere.Suitable materials for the waterproofing membrane are here high polymer sheets, especially thermoplastics like EVA, PVC, polyolefins, thermoplastic elastomers and elastomers.

Weiterhin ist vorteilhafterweise die Abdichtungsbahn über den Fugen aus demselben Material gebildet, wie die Abdichtungsbahn bzw. Folienkaschierung der Metallelemente.Furthermore, the sealing membrane is advantageously over the joints are made of the same material as the waterproofing membrane or foil lamination of the metal elements.

Mit besonderem Vorteil ergibt sich die Möglichkeit einer einfachen Befestigung des bzw. der Metallelemente an der Dachkonstruktion. Hierzu wird ein Befestigungselement verwendet, das einen Kopfabschnitt und einen Gewindeabschnitt aufweist, wobei der Gewindeabschnitt sich von der Außenseite nach innen erstreckt und damit mit der darunterliegenden Dachkonstruktion statisch sicher verbindbar ist. Durch den Kopfabschnitt erfolgt mittels Verschweißúng oder Verklebung eine dauerhafte und sichere Abdeckung und Abdichtung der Durchbruchstelle. Dadurch wird ermöglicht, daß das Befestigungselement bei ebenen Metallelementen an allen gewünschten Stellen bzw. bei Profil-Metallelementen in deren Profiltälern oder deren Hochsicken angeordnet werden kann. Weiterhin ist es möglich, das Befestigungselement mit einer entsprechenden Abdichtungsbahn zu überdecken.The possibility of a is particularly advantageous simple attachment of the metal element (s) to the Roof construction. A fastener is used for this, a head section and a threaded section has, wherein the threaded portion is from the outside extends inwards and thus with the one below Roof structure is statically securely connectable. By the Head section is done by welding or gluing permanent and secure covering and sealing of the Breakthrough. This allows the fastener with flat metal elements on all desired Places or with profile metal elements in their profile valleys or their raised beads can be arranged. It is also possible to attach the fastener with a cover the corresponding sealing membrane.

Vorteilhafterweise wird eine Abdichtungsbahn auch an Durchbrüchen, wie beispielsweise Kaminen in dem Metallelement auf der Außenseite angebracht, so daß hier wiederum eine langlebige Abdichtung erfolgt.A sealing membrane is also advantageously made at openings, such as chimneys in the metal element attached on the outside, so that here again durable sealing takes place.

Aufgrund der dehnbaren Abdichtungsbahn können somit Längenänderungen in den Metallelementen ausgeglichen werden, so daß die Eigenschaft der Wasserdichtheit über einen extrem langen Zeitraum sichergestellt ist, was insbesondere durch die gute Alterungsbeständigkeit der Abdichtungsbahn unterstützt wird.Due to the stretchable waterproofing membrane, changes in length can be made be balanced in the metal elements, so that the property of water resistance over an extreme long period of time, which is ensured in particular by supports the good aging resistance of the waterproofing membrane becomes.

Darüberhinaus ist aufgrund der Elastizität der Außenhaut des erfinderischen Metalldaches besonderer Schutz gegen Hagelschaden gegeben.Furthermore, due to the elasticity of the outer skin The inventive metal roof provides special protection against hail damage given.

Wie ersichtlich befindet sich zwischen dem perspektivisch dargestellten Metallelement 3 und einer benachbarten Wand 63 eine kastenförmige Rinne 61, die einen Anhängabschnitt 65 und einen Auflageabschnitt 67 aufweist. Der Anhängeabschnitt 65 ist ein einstückig mit der Kastenrinne 61 mehrfach abgekanteter Endabschnitt, der sich um den oberen Rand 69 der Wand 63 erstreckt.In Figure 8 is a so-called "parapet connection" with inside Box gutter 61 shown. As can be seen between the metal element shown in perspective 3 and an adjacent wall 63 a box-shaped Trough 61, which has a trailer section 65 and a Has support section 67. The appendage portion 65 is an integral with the box gutter 61 multiple times End portion that extends around the upper edge 69 of the wall 63 extends.

Das Metallelement 3 liegt auf dem Auflageabschnitt 67 auf. Zur Erzeugung der Wasserdichte ist eine als Abdichtungsbahn 12 ausgebildete Kunststofffolie 71 vorgesehen, die streifenartig ausgebildet ist. Ein Teil 73 ist mit dem Metallelement 3 verbunden und ein Rinnenteil 75 ist mit der Kastenrinne verbunden. Damit ist durch die elastische Kunststofffolie eine sichere Abdichtung des Fugenbereichs zwischen Metallelement 3 und Kastenrinne 61 sichergestellt.The metal element 3 lies on the support section 67. To create the watertightness is a waterproofing membrane 12 formed plastic film 71 is provided, the strip-like is trained. Part 73 is with the metal element 3 connected and a gutter part 75 is with the box gutter connected. So that's through the elastic plastic film secure sealing of the joint area between Metal element 3 and box gutter 61 ensured.

Mit der vorliegenden Erfindung wird somit universell eine wasserdichte Abdichtung eines Metalldaches erreicht, wobei zusätzlich der Vorteil besteht, daß im Innenraum derartig abgedeckter Gebäude mögliche Feuchtigkeits- und Kondenswasserbildungen abgefangen werden können. Damit wird eine langlebige einfach aufgebaute und entsprechend kostengünstige Dachabdeckung geschaffen, die ein extrem hohe Lebensdauer aufweist. Sie kann universell verwendet werden, insbesondere im Anschluß der einzelnen Elemente untereinander, im Wandanschluß bzw. im Anschluß an irgendwelche Rinnen, Kamine oder dergleichen. Wie bereits angegeben können die metallelemente 3 jegliche beliebige Form, wie Profilelemente, Flachelemente, wellenförmige Elemente, Stehfalze etc aufweisen.The present invention thus becomes universal achieved waterproof sealing of a metal roof, whereby In addition, there is the advantage that such an interior covered building possible moisture and condensation can be intercepted. So that becomes a durable, simply constructed and correspondingly inexpensive Roof cover created that have an extremely long lifespan having. It can be used universally, especially after the individual elements, in the wall connection or in connection with any gutters, Fireplaces or the like. As already stated, the metal elements 3 any shape, such as profile elements, Flat elements, wavy elements, standing seams etc exhibit.

Die vorliegende Erfindung ist nicht auf die dargestellten Beispiele beschränkt. So kann anstelle der wasserbalancierenden Kaschierung auch eine (untere) Abdichtungsbahn vorgesehen werden. Dies ermöglicht vorteilhafterweise benachbarte Metallelemente teilweise übereinanderzusetzen, so daß die untere Abdichtungsbahn des einen Elements die ober Abdichtungsbahn des benachbarten Elementes teilweise überdeckt und beide Bahnen auf einfache Weise wasserdicht verklebt oder verschweißt werden können.The present invention is not shown on the Examples limited. So instead of water balancing Lamination also provided a (lower) waterproofing membrane become. This advantageously enables neighboring ones Partially stack metal elements so that the lower sealing membrane of one element the upper sealing membrane of the neighboring element partially covered and easily glued both sheets waterproof or can be welded.
