Description

Die vorliegende Erfindung betrifft ein Dachbelagmaterial, ein Verfahren zur Montage des Dachbelages und eine Dachkonstruktion, in der der Dachbelag und das erfindungsgemässe Verfahren zur Anwendung kommen. Insbesondere betrifft die Erfindung Dachbeläge,für die langgestreckte profilierte Metallplatten verwendet werden. Gemäss dem Oberbegriff von Anspruch 1, betrifft die Erfindung eine langgestreckte in Querrichtung profilierte Dachplatte mit mindestens einer längsgerichteten Wölbung und an diese anschliessende Profiltäler und erste und zweite Kantenprofilierungen längs entgegengesetzter Kanten der Platte.The present invention relates to a roof covering material, a method for assembling the roof covering and a roof construction in which the roof covering and the method according to the invention are used. In particular, the invention relates to roofing for which elongated profiled metal plates are used. According to the preamble of claim 1, the invention relates to an elongated roof panel profiled in the transverse direction with at least one longitudinal curvature and adjoining profile valleys and first and second edge profiles along opposite edges of the panel.

Solche Dachplatten sind in verschiedensten Formen bekannt, siehe PCT Veröffentlichung WO 82/04277. Bei dieser Konstruktion ist auch bereits ein Uberhang vorgesehen, der das Eindringen zwischen die Platten von Wasser durch Kapillarwirkung verhindern soll.Such roof panels are known in various forms, see PCT publication WO 82/04277. With this construction, an overhang is already provided which is intended to prevent water from penetrating between the plates by capillary action.

Gemäss internationaler Normen sollten Dachbeläge dieser Art mindestens sechs Befestigungsstellen pro Quadratmeter aufweisen. Für Dächer langer Spannweite nicht herkömmlicher Art, z.B. mit 1,5 bis 2 m Zwischenräumen zwischen den Dachpfetten ergeben sich hieraus Schwierigkeiten, insbesondere hinsichtlich der wetterfesten Abdichtung. Zur Vermeidung von Löchern in der Plattenfläche selbst müssen die einzelnen Platten verhältnismässig schmal sein, damit sich die geforderte Anzahl Befestigungsstellen auch dann verwirklichen lässt, wenn nur die Längskantenbereiche der Platten befestigt werden. Da die Montage schnell vonstatten gehen muss, stellt die gründliche Abdichtung zwischen aneinandergrenzenden Platten hohe Anforderungen an die Dachdecker. Ausserdem verwendet man für Flächen hoher Spannweite im allgemeinen sehr lange Platten, was mit sich bringt, dass die thermische Ausdehnung ebenfalls berücksichtigt werden muss. Beispielsweise gelten für verschiedene herkömmliche Dachbeläge folgende thermische Ausdehnungskoeffizienten: 1 x 10-5/°C für verzinktes Eisenblech, 3 x 10-5/°C für Titanium-zinklegierung und 2 x 10-5/°C für Aluminium, was bedeutet, dass über eine Länge von 10m und einen Temperaturbereich von nur 40°C Relativbewegungen von zwischen 4 und l2mm zu erwarten sind. Weitere Probleme ergeben sich aus Seitenwindeffekten, sowie Kapiltarkräften, wodurch Regenwasser, z.B: zwischen die überlappenden Dachbelagbereiche eindringen kann. Auch dieses Problem wird durch den oben zitierten Stand der Technik nur teilweise überwunden, da dort nach wie vor grössere Uberlappungszonen mit Kapillarwirkung vorliegen, in die Wasser unter Winddruck eindringen kann.According to international standards, roofing of this type should have at least six fastening points per square meter. For roofs with a long span of a non-conventional type, for example with 1.5 to 2 m spaces between the roof purlins, this results in difficulties, in particular with regard to the weatherproof sealing. In order to avoid holes in the plate surface itself, the individual plates must be relatively narrow so that the required number of fastening points remains even then can be realized if only the longitudinal edge areas of the panels are attached. Since assembly must be quick, the thorough sealing between adjacent panels places high demands on roofers. In addition, very long plates are generally used for surfaces with a wide span, which means that the thermal expansion must also be taken into account. For example, the following coefficients of thermal expansion apply to various conventional roof coverings: 1 x 10 -5 / ° C for galvanized iron sheet, 3 x 10 -5 / ° C for titanium-zinc alloy and 2 x 10 -5 / ° C for aluminum, which means that Over a length of 10m and a temperature range of only 40 ° C, relative movements of between 4 and l2mm are to be expected. Other problems arise from cross wind effects and capillary forces, which means that rainwater, for example: can penetrate between the overlapping roof covering areas. This problem is also only partially overcome by the prior art cited above, since there are still larger overlap zones with capillary action, into which water can penetrate under wind pressure.

Die vorliegende Erfindung soll den obenbeschriebenen Problemen entgegenwirken. Erfindungsgemäss wird dies mit einer Vorrichtung der eingangsgenannten Art dadurch erreicht, dass die erste Kantenprofilierung einander gegenüberliegende erste Kantenflanken besitzt, die einander in einem umgebogenen Flansch begegnen, der einen von der ersten Kantenflanke nach innen gerichtet sich erstreckenden Eingrifflansch bildet, während die zweite Kantenprofilierung eine zweite Kantenflanke besitzt, von der aus ein Wellensattel nach aussen ragend sich erstreckt, und zur Bildung einer Eingriffsrille unter dem Wellensattel zurückgebogen ist.The present invention is intended to counter the problems described above. According to the invention, this is achieved with a device of the type mentioned at the outset in that the first edge profiling has mutually opposite first edge flanks which are in each other encounter a bent flange which forms an engagement flange which extends inwards from the first edge flank, while the second edge profiling has a second edge flank from which a shaft saddle projects outwards and is bent back to form an engagement groove under the shaft saddle.

Die Kantenprofilierungen aneinander grenzender Dachplatten werden dadurch miteinander verhakt, dass jeweils der Eingriffsflansch der einen Platte in die Eingriffsrille der anderen Platte einhakt. Vorzugsweise besitzt die erste Kantenflanke jeweils längs der Unterkante, einen nach oben gerichteten Steg zur Bildung einer Wasserablaufrinηe für den Fall, dass doch Wasser in die Verbindung eindringt.The edge profiles of adjoining roof panels are hooked together in that the respective engagement flange of one panel hooks into the engagement groove of the other panel. Preferably, the first edge flank along the lower edge has an upwardly directed web to form a water drainage ring in the event that water does enter the connection.

Die in der Beschreibungseinleitung genannten Probleme werden gemäss der Weiterbildung der Erfindung dadurch beseitigt, dass zur Befestigung der Dachplatten an der Dachstuhlkonstruktion Befestigungsschellen vorgesehen sind, wobei jede Schelle zur Befestigung an einem Teil der Dachstuhlkonstruktion, insbesondere einer Pfette eingerichtet ist, sowie ein Klammerteil besitzt für den Eingriff mit einem Teil der ersten Kantenprofilierung, dadurch gekennzeichnet, dass die Schelle dazu eingerichtet ist,entweder den Eingriffsflansch der ersten Kantenprofilierung einer Dachplatte oder den nach oben gerichteten Steg der ersten Kantenflanke einer Dachplatte zu umfassen.The problems mentioned in the introduction to the description are eliminated according to the development of the invention in that fastening clamps are provided for fastening the roof panels to the roof structure, each clamp being set up for fastening to a part of the roof structure, in particular a purlin, and having a clamp part for the Engagement with part of the first edge profiling, characterized in that the clamp is set up for this is to encompass either the engagement flange of the first edge profile of a roof panel or the upward web of the first edge flank of a roof panel.

Gemäss einer weiteren Variante des Eingriffsflansches und der erfindungsgemässen Dachplatte, besitzen die Flanken der ersten Kantenprofilierung der Platten ein Basisteil mit einem nach oben gerichteten Steg solcher Art, dass ein Befestigungsteil (z.B. Nagel, Schraube oder Bolzen) durch das Basisteil in die Dachstuhlkonstruktion getrieben werden kann, wobei der Steg gleichzeitig eine Wasserablaufrinne bildet.According to a further variant of the engagement flange and the roof plate according to the invention, the flanks of the first edge profiling of the plates have a base part with an upwardly directed web such that a fastening part (e.g. nail, screw or bolt) can be driven through the base part into the roof structure , the web also forming a water drainage channel.

Gemäss einer Weiterbildung der Erfindung wird das Problem der Undichtigkeit auf Grund der obengenannten Kapillarwirkung mittels einer Dachplatte mit Eingriffsflansch und Eingriffsrille der obengenannten Art dadurch gelöst, dass der Eingriffsflansch nach unten und zum Wellentrog der Dachplatte hin geneigt ist. Durch diese Neigung ergeben sich beim Eingriff des Eingriffsflansches in die Eingriffsrille Hohlräume oder Luftkammern, die die Kapillarwirkung unterbrechen. Vorzugsweise befindet sich am freien Ende des zurückgebogenen Teiles der zweiten Kantenprofilierung im Anschluss an die Eingriffsrille eine nach unten und vorzugsweise nach aussen gebogene Stegkante. Diese ist vorzugsweise so ausgebildet, dass sie mit der Flanke der ersten Kantenprofilierung einer anschliessenden Platte zusammenwirkt zur Bildung eines Hohlraumes, der das Eindringen von Wasser durch die Plattenverbindung unter Winddruck verhindert.According to a development of the invention, the problem of leakage due to the above-mentioned capillary action is solved by means of a roof plate with an engagement flange and engagement groove of the above-mentioned type in that the engagement flange is inclined downwards and towards the trough of the roof plate. This inclination results in cavities or air chambers which interrupt the capillary action when the engaging flange engages in the engaging groove. At the free end of the bent-back part of the second edge profiling, there is preferably a web edge bent downwards and preferably outwards, following the engagement groove. This is before preferably designed so that it interacts with the flank of the first edge profile of a subsequent plate to form a cavity which prevents water from penetrating through the plate connection under wind pressure.

Das oben angeschnittene Problem der Montage der Dachplatten wird gemäss einer Weiterbildung der Erfindung durch ein Verfahren zur Installation der oben beschriebenen Dachplatten dadurch gelost, dass zunächst eine Dachplatte auf den Dachstuhl aufgelegt wird, die erste Kantenprofilierung der Platte am Dachstuhl befestigt wird, eine zweite Platte geneigt zur ersten Platte, aufgestellt und die zweite Kantenprofilierung der zweiten Dachplatte mit der ersten Kantenprofilierung der bereits montierten ersten Dachplatte in Eingriff gebracht wird, danach die zweite Dachplatte durch Schwenkung in Position gebracht wird, und die erste Kante der zweiten Platte befestigt wird, welcher Vorgang mit weiteren Platten je nach der Grösse der Dachfläche beliebig oft wiederholt wird.According to a further development of the invention, the above-mentioned problem of mounting the roof panels is solved by a method for installing the roof panels described above, that first a roof panel is placed on the roof truss, the first edge profile of the panel is attached to the roof truss, and a second panel is inclined to the first plate, set up and the second edge profile of the second roof plate is brought into engagement with the first edge profile of the already installed first roof plate, then the second roof plate is brought into position by pivoting, and the first edge of the second plate is fastened, which process with other plates depending on the size of the roof surface is repeated as often as required.

Figur 2 zeigt wie die Dachplatte gemäss Figur 1 auf eine Dachstuhlkonstruktion mit Dachpfetten 40 montiert wird, die sich quer zu den Längswellen der Dachplatte erstrecken. Dachhautplatten 60 und 70 werden an der Dachpfette 40 mittels einer Befestigungsschelle 50 (die auch breiter sein kann wie in Figur 3 gezeigt) und eines Hakenbolzens 61 befestigt. Die Kantenprofilierung der Kante 60 besitzt eine geneigte Flanke 62, einen Eingriffsflansch 66 und eine etwa senkrechte Flanke 64, wobei der Eingriffsflansch hinsichtlich der Flanke 64 um 1050 umgebogen ist, und somit zum Wellentrog der Platte hin nach unten geneigt ist. Ein aufwärts ragender Steg 68 am freien Ende der Flanke 64 bildet eine Wasserablaufrille. Die Kantenprofilierung der Platte 70 besitzt eine geneigte Flanke 72, einen Wellensattel 74, einen zurückgebogenen Flansch 76 und einen Abtropfsteg 78.FIG. 2 shows how the roof panel according to FIG. 1 is mounted on a roof structure with purlins 40 that extend transversely to the longitudinal waves of the roof panel. Roof skin panels 60 and 70 are fastened to the purlin 40 by means of a fastening clamp 50 (which can also be wider as shown in FIG. 3) and a hook bolt 61. The edge profiling of the edge 60 has an inclined edge 62, an engagement flange 66 and an approximately vertical edge 64, where the engagement flange is bent by 105 0 with respect to the edge 64, and is thus inclined to the wave trough of the plate downwards. An upwardly projecting web 68 at the free end of the flank 64 forms a water drainage groove. The edge profiling of the plate 70 has an inclined flank 72, a shaft saddle 74, a bent back flange 76 and a drip web 78.

Der Wellensattel 74 erstreckt sich im wesentlichen parallel zu den Trögen der Platten 60 und 70, d.h. wenigstens nach der Montage. Die Eingriffsrille zwischen dem Wellensattel 74 und dem umgebogenen Flansch 76 nimmt den Eingriffsflansch 66 mit federnd angespanntem festen Sitz auf. In der praktischen Anwendung der Montage der Platte 70, hält man diese zunächst mit der gezeigten Kante nach unten geneigt, bringt den Flansch 66 mit der Eingriffsrille in Eingriff, schwenkt dann die Platte 70 bis sie parallel zur Platte 60 liegt, und zieht die Platte 70 von der Platte 60 so weg, dass der Steg 78 mit der Flanke 62 zur Anlage kommt. Dadurch werden die Flansche 64 und 66 federnd miteinander verspannt, wodurch Klappern des Dachbelages vermieden wird, ein Faktor der sonst erfahrungsgemäss zum Lösen der Befestigungsteile, beispielsweise Nägel, fuhrt. Durch die gezeigte Anordnung ergeben sich auch Luftkammern A und B in der Verbindung. Diese besitzen einen verhältnismässig grossen Querschnitt, und unterbrechen dadurch die Kapillarwirkung, wodurch das Eindringen von Wasser durch die Verbindung unter Kapillarkraft verhindert wird. Die Verwendung einer Befestigungsschelle in der Dachkonstruktion ermöglicht es den Dachplatten,sich unter dem Einfluss von Temperaturänderungen auszudehnen und zu schrumpfen, ohne die Einwirkung hoher Kräfte auf die Befestigungsteile. Die Befestigungsschelle 59 stellt eine Variante dar, die in den Steg 68 einhakt.The shaft saddle 74 extends substantially parallel to the troughs of the plates 60 and 70, ie at least after assembly. The engagement groove between the shaft saddle 74 and the bent flange 76 receives the engagement flange 66 with a spring-loaded tight fit. In the practical application of mounting the plate 70, first holding it with the edge shown downward, bringing the flange 66 into engagement with the engaging groove, then pivoting the plate 70 until it is parallel to the plate 60, and pulling the plate 70 away from the plate 60 so that the web 78 comes to rest with the flank 62. As a result, the flanges 64 and 66 are resiliently clamped to one another, thereby preventing rattling of the roof covering, a factor which, based on experience, otherwise leads to loosening the fastening parts, for example nails. The arrangement shown also results in air chambers A and B in the connection. These have a relatively large cross-section, thereby interrupting the capillary action, which prevents the penetration of water through the connection under capillary force. The use of a fastening clamp in the roof construction enables the roof panels to expand and shrink under the influence of temperature changes, without the action of high forces on the fastening parts. The fastening clamp 59 represents a variant which hooks into the web 68.

Figur 3 zeigt eine Befestigungsschelle 50 mit einem Basisteil 52 und zwei Löchern 53 darin, zur Befestigung am Dachstuhl, einer nach oben gerichteten Fläche 54 und einem Klammerteil 56 mit einem zurückgebogenen Steg 58, der eine Eingriffsrille bildet, die den Eingriffsflansch 26 einer Kantenprofilierung aufnimmt.FIG. 3 shows a fastening clamp 50 with a base part 52 and two holes 53 therein, for fastening to the roof structure, an upwardly facing surface 54 and a bracket portion 56 with a bent-back web 58 which forms an engagement groove which receives the engagement flange 26 of an edge profile.

Figur 4 zeigt ein Ausführungsbeispiel ohne Befestigungsschellen. In dieser Abbildung wird eine Kantenprofilierung 116 einer Dachplatte an der Pfette 40 mittels eines durch ein Basisteil 28 getriebenen Nagels 42 befestigt. Gegebenenfalls kann man auch an Stelle des Nagels 42 und der hölzernen Dachpfette 40 in an sich bekannter Weise eine Metallprofilpfette und Hakenbolzen verwenden. Die Kantenprofilierung 118 einer angrenzenden Dachplatte ist in die bereits am Dachstuhl befestigte zuerst genannte Dachplatte eingehakt, wobei die vom zuruckgebogenen Teil 136 der Kantenprofilierung 118 gebildete Eingriffsrille mit dem Eingriffsflansch 126 der Kantenprofilierung 116 in Eingriff gebracht ist. Gemäss der Abbildung liegt der Steg 138 gegen die Flanke 122 der Kantenprofilierung 116 an und bildet eine Luftkammer B ausreichender Grösse zur Verhinderung der Kapillarwirkung, wenn Wasser durch Sturmeinwirkung an der Flanke 122 hochgeblasen wird. Man sieht auch wie der Eingriffsflansch 126 nach unten geneigt ist; dadurch bildet sich eine zweite Luftkammer A, was ebenfalls dazu dient, das Hindurchsickern von Wasser durch die Verbindung zwischen aneinandergrenzenden Dachplatten zu verhindern. Eine Schicht "Mastic"(Handelsname) oder ähnlicher bituminöser Dichtungsmasse 46 befindet sich zwischen dem Flansch 126 und dem Wellensattel 134. Das Basisteil 28 besitzt einen nach oben gebogenen Steg 29 und wird dadurch zur Wasserablaufrinne.Figure 4 shows an embodiment without mounting clips. In this figure, an edge profile 116 of a roof panel is fastened to the purlin 40 by means of a nail 42 driven by a base part 28. If necessary, a metal profile purlin and hook bolts can also be used instead of the nail 42 and the wooden roof purlin 40 in a manner known per se. The edge profile 118 of an adjacent roof panel is hooked into the first roof panel already fastened to the roof frame, the engagement groove formed by the bent-back part 136 of the edge profile 118 being brought into engagement with the engagement flange 126 of the edge profile 116. According to the illustration, the web 138 bears against the flank 122 of the edge profiling 116 and forms an air chamber B of sufficient size to prevent the capillary action when water is blown up on the flank 122 by the action of a storm. It can also be seen how the engagement flange 126 is inclined downwards; this forms a second air chamber A, which also serves to allow water to seep through to prevent the connection between adjacent roof tiles. A layer of "Mastic" (trade name) or similar bituminous sealant 46 is located between the flange 126 and the shaft saddle 134. The base part 28 has an upwardly curved web 29 and thereby becomes a water drainage channel.

Beim Montieren eines Daches mit den obenbeschriebenen Dachplatten werden die Dachplatten nacheinander in seitlicher Richtung installiert. Das heisst also, dass eine Dachplatte angrenzend an eine Plattenkante zunächst an der Dachstuhlkonstruktion befestigt wird, wobei gleichzeitig die Kantenprofilierung 16 befestigt wird. Eine angrenzende Dachplatte wird dann mit der bereits befestigten Kantenprofilierung 116 in Eingriff gebracht, und deren Kantenprofilierung 116 wird ihrerseits am Dachstuhl befestigt. In dieser Weise können die Dachplatten schnell und mit einem Minimum an Befestigungsteilen,die ausserdem versteckt und gegen die Witterung geschützt sind, montiert werden.When installing a roof with the roof panels described above, the roof panels are installed one after the other in the lateral direction. This means that a roof panel adjacent to a panel edge is first attached to the roof structure, the edge profile 16 being attached at the same time. An adjacent roof panel is then brought into engagement with the already attached edge profile 116, and the edge profile 116 is in turn attached to the roof structure. In this way, the roof panels can be installed quickly and with a minimum of fastening parts, which are also hidden and protected against the weather.

Die Erfindung beschränkt sich nicht auf die genauen in der Zeichnung abgebildeten und hier beschriebenen Konstruktionseinzelheiten. Variationsmöglichkeiten sind im Rahmen des Erfindungsgedankens und Schutzumfanges gegeben. Zum Beispiel kann eine Befestigungsschelle vorgesehen sein, die lediglich den Steg 68 einer Dachplatte erfasst. In dem Falle kann man ein entsprechendes Dichtungsmittel vorsehen zur Abdichtung des Flansches 64 in der Rille zwischen den Teilen 74 und 76 aneinandergrenzender Platten. Der Rillensattel und der Eingriffsflansch können auch mit Hohlnieten vernietet werden, wobei die Nieten vorzugsweise nicht ganz durch die sich überlappenden Flansche hindurchgesteckt werden.The invention is not limited to the precise construction details shown in the drawing and described here. Variations are possible within the scope of the inventive concept and scope of protection. For example, a fastening clamp can be provided which only engages the web 68 of a roof panel. In this case, a suitable sealing means can be provided for sealing the flange 64 in the groove between the parts 74 and 76 of adjoining plates. The grooved saddle and the engagement flange can also be riveted with hollow rivets, the rivets preferably not being pushed completely through the overlapping flanges.

Die Erfindung ist auch nicht auf Dachplatten aus Metallblech beschränkt. Es können auch Kunststoffplatten, Glas-faser-verstärkte Kunststoffplatten, Zement-gebundene Faserplatten, Verbundmaterialien und dergleichen verwendet werden, die in ähnlicher Weise wie die Blechplatten profiliert sein können.The invention is also not limited to sheet metal roof panels. Plastic sheets, glass fiber reinforced plastic sheets, cement-bonded fiber sheets, composite materials and the like can also be used, which can be profiled in a similar manner to the sheet metal sheets.
