Description

Vorrichtung zur Befestigung eines Anbauteils Device for fastening an attachment
Die vorliegende Erfindung betrifft eine Vorrichtung zur Befestigung eines Anbauteils am Untergrund eines Bauwerks oder eines Fahrzeugs mittels eines Befestigungselements, das ortsfest mit dem Untergrund verbunden ist. Derartige Vorrichtungen kommen beispielsweise an Gebäudedächern zur Befestigung von Dachaufbauten zum Einsatz.The present invention relates to a device for fastening an attachment to the substrate of a building or a vehicle by means of a fastener which is fixedly connected to the ground. Such devices are used for example on building roofs for attachment of roof structures for use.
Bisher werden Dachaufbauten vor allem bei Bauwerken, z. B. Solaranlagen, häufig direkt mit der jeweiligen Tragkonstruktion des entsprechenden Gebäudes verbunden. Die dabei verwendeten Befestigungsbauteile, etwa Schrauben, durchdringen die Dachoberfläche des Gebäudes und verstärken damit die Anfälligkeit der Dachoberfläche für witterungsbedingte Undichtigkeiten. Alternativ ist es auch bekannt, Dachaufbauten durch Auflast auf der Dachoberfläche anzubringen. Hierbei wird in der Regel zumindest eine mit Ballast versehene Wanne auf der Dachoberfläche kraftschlüssig fixiert, an der dann wiederum der jeweilige Dachaufbau befestigt ist. Dies erfordert je nach Anwendungsfall eine erhebliche Menge an Ballast, was die Statik der gesamten Dachkonstruktion unnötig belastet.So far roof structures are mainly in buildings, eg. As solar systems, often directly connected to the respective support structure of the corresponding building. The fasteners used, such as screws, penetrate the roof surface of the building and thus increase the vulnerability of the roof surface for weather-related leaks. Alternatively, it is also known to attach roof structures by ballast on the roof surface. In this case, at least one tank provided with ballast is usually fixed on the roof surface non-positively, on which in turn the respective roof structure is attached. This requires depending on the application, a significant amount of ballast, which unnecessarily burdened the statics of the entire roof construction.
Darüber hinaus beschreibt die DE 295 17 085 U1 eine Montagehalterung für Photo- voltaik-Solarmodule zur Befestigung auf ebenen Flächen von Wohnmobilen, Wohnwagen, Booten, Wochenendhäusern etc.. Diese Montagehalterung wird mit der ebenen Fläche verklebt, wobei an der Montagehalterung das Solarmodul verschraubt wird. Als nachteilig wird hierbei die eingeschränkte Verwendung der Montagehalterung lediglich bei ebenen Flächen angesehen. Darüber erweist sich die die Haltbarkeit der Klebeverbindung zwischen der schienenförmigen Montagehalterungen und der ebenen Flächen insbesondere bei hohen Belastungen als unzureichend. Angesichts dessen besteht die Aufgabe der vorliegenden Erfindung in der Gestaltung einer universell einsetzbaren Vorrichtung zur Befestigung von einem Anbauteil an einem Bauwerk oder einem Fahrzeug, welche bei allen Anwendungsfällen einen sicheren Halt gewährleistet und das Bauwerk oder das Fahrzeug anderweitig nicht negativ beeinflusst.In addition, DE 295 17 085 U1 describes a mounting bracket for photovoltaic solar modules for mounting on flat surfaces of campers, caravans, boats, weekend homes, etc. This mounting bracket is glued to the flat surface, wherein the solar module is screwed to the mounting bracket , A disadvantage here is the limited use of mounting bracket considered only on flat surfaces. In addition, the durability of the adhesive bond between the rail-shaped mounting brackets and the flat surfaces proves to be inadequate, especially at high loads. In view of this, the object of the present invention in the design of a universally applicable device for attachment of an attachment to a building or a vehicle, which ensures a secure fit in all applications and otherwise does not adversely affect the building or the vehicle.
Gelöst wird diese Aufgabe durch eine Vorrichtung zur Befestigung von einem Anbauteil am Untergrund eines Bauwerks oder eines Fahrzeugs mit einem Befestigungselement, das ortsfest mit dem Untergrund verbunden ist und Befestigungsmittel zur lösbaren Befestigung des Anbauteils aufweist. Derartige Anbauteile sind etwa als Dachaufbauten (z. B. Solaranlagen, Antennen, Satellitenempfangsanlegen etc.) ausgebildet, die üblicherweise auf dem Dach eine Bauwerks oder eines Fahrzeugs montiert werden. Eine derartiger Untergrund, beispielsweise an einer zugehörigen Dachfläche, umfasst üblicherweise eine Tragkonstruktion, die ein die entsprechende Last tragendes Gerüst bildet, und eine in der Regel an der Oberfläche liegende Schicht, die gegenüber Witterungseinflüssen abdichtet. Neuerungsgemäß ist das Befestigungselement durchdringungsfrei an der Schicht befestigt sowie ortsfest gegenüber der Tragkonstruktion positioniert. Die durchdringungsfreie Befestigung an der Schicht erhält wie gewünscht die Witterungsbeständigkeit während die ortsfeste Positionierung gegenüber der Tragkonstruktion den sicheren Halt des Befestigungselements am Untergrund bewirkt.This object is achieved by a device for attachment of an attachment to the substrate of a building or a vehicle with a fastener which is fixedly connected to the ground and has fastening means for releasably securing the attachment. Such add-on parts are designed, for example, as roof structures (eg solar systems, antennas, satellite reception systems, etc.) which are usually mounted on the roof of a building or a vehicle. Such a base, for example on an associated roof surface, usually comprises a supporting structure which forms a framework carrying the corresponding load, and a layer which is generally located on the surface and which seals against the effects of weathering. According to the innovation, the fastening element is attached without penetration to the layer and positioned in a stationary position relative to the supporting structure. The penetration-free attachment to the layer obtains the weather resistance as desired while the stationary positioning relative to the support structure causes the secure attachment of the fastener to the ground.
Gemäß einer bevorzugten Ausführung ist die Schicht zumindest im Bereich des Befestigungselements ortsfest mit der Tragkonstruktion verbunden. Auf diesem Wege können an dem Anbauteil bzw. am Befestigungselement angreifende Kräfte, z. B. Windkräfte, zuverlässig in die Tragkonstruktion eingeleitet werden.According to a preferred embodiment, the layer is at least in the region of the fastening element fixedly connected to the support structure. In this way, on the attachment or on the fastener attacking forces, eg. As wind forces are reliably initiated in the supporting structure.
Eine weitere sinnvolle Variante der Vorrichtung sieht vor, die Schicht im Bereich des Befestigungselements mittels eines zusätzlichen Halters ortsfest mit der Tragkonstruktion zu verbinden. Dieser Halter ist zur sicheren Kraftübertragung ausreichend zu dimensionieren und unterstützt die schadensfreie Krafteinleitung in die Tragkonstruktion vor allem bei fehlender oder unzureichender Befestigung der Schicht an der Tragkonstruktion.Another useful variant of the device provides to connect the layer in the region of the fastener by means of an additional holder stationary with the support structure. This holder is sufficient for safe power transmission To dimension and supports the damage-free force transmission into the supporting structure, especially in the absence or insufficient attachment of the layer to the supporting structure.
Eine sehr einfache und gleichsam wirkungsvolle Vorrichtung zur Befestigung wird dadurch erreicht, dass die Schicht aus Kunststoff ausgeführt ist. Dies ermöglicht unter anderem die Verwendung unterschiedlicher durchdringungsfreier Verbindungstechniken zwischen Schicht und Befestigungselement, so z. B. kleben, schweißen etc..A very simple and effective as attachment device is achieved in that the layer is made of plastic. This allows, inter alia, the use of different penetration-free bonding techniques between layer and fastener, such. B. gluing, welding etc.
Eine funktionale Verbesserung des Befestigungselements ergibt sich dadurch, dass das Befestigungselement einen flexiblen Basisabschnitt, der an der Schicht befestigt ist, und einen Kern umfasst, der gegenüber dem Basisabschnitt höhere Festigkeit aufweist und an dem das Befestigungsmittel ausgebildet ist. Dabei besteht das Befestigungselement vorzugsweise aus einem thermoplastischen Kunststoff, z. B. auf Basis von weichem Polyvinylchlorid PVC-P, Ethylenvinylacetat EVAC, flexiblen PoIy- oefinen FPO, Vinylacetat-Ethylen VAE oder vergleichbaren Materialien. Der flexible Basisabschnitt lässt sich durch geeignete Materialauswahl besonders gut an der Schicht befestigen und sorgt aufgrund seiner flexiblen Materialeigenschaften für eine gleichmäßige Krafteinleitung in den Untergrund bzw. die Tragkonstruktion ohne die insbesondere an der Untergrundoberfläche angeordnete Schicht zu beschädigen. Der Kern weist gemäß einer vorteilhaften Weiterentwicklung eine höhere Shorehärte als der Basisabschnitt auf und ist demnach gezielt im Hinblick auf die sichere Befestigung sowie zuverlässige Kraftübertragung ausgelegt. Das ebenfalls am Kern ausgebildete Befestigungsmittel dient der lösbaren Befestigung des Anbauteils und ist beispielsweise als Buchse, vorzugsweise Gewindebuchse, oder als Bolzen, vorzugsweise als Gewindebolzen, ausgeführt.A functional improvement of the fastener results from the fact that the fastener comprises a flexible base portion which is attached to the layer, and a core which has higher strength relative to the base portion and on which the fastening means is formed. In this case, the fastening element preferably consists of a thermoplastic material, for. B. on the basis of soft polyvinyl chloride PVC-P, ethylene vinyl acetate EVAC, flexible poly oefinen FPO, vinyl acetate ethylene VAE or similar materials. Due to its flexible material properties, the flexible base section can be fastened particularly well to the layer by means of a suitable choice of material and, due to its flexible material properties, ensures a uniform introduction of force into the substrate or supporting structure without damaging the layer, which is arranged in particular on the substrate surface. The core has, according to an advantageous development, a higher Shore hardness than the base portion and is therefore designed specifically with regard to the secure attachment and reliable power transmission. The likewise formed on the core fastener is used for releasably securing the attachment and is for example as a bushing, preferably threaded bushing, or as a bolt, preferably as a threaded bolt executed.
Zur weiteren Vereinfachung des Befestigungselements ist dieses mittels Spritzgusstechnik hergestellt, insbesondere unter Verwendung von mehreren Materialien unterschiedlicher Festigkeit bzw. Shorehärte. Weitere sinnvolle Details der Erfindung ergeben sich auch aus den in den Zeichnungen dargestellten Ausführungsbeispielen, die im folgenden näher erläutert werden.To further simplify the fastener this is made by injection molding, in particular using a plurality of materials of different strength or Shore hardness. Further meaningful details of the invention will become apparent from the embodiments illustrated in the drawings, which are explained in more detail below.

Die Figuren verdeutlichen eine Vorrichtung zur Befestigung eines Anbauteils 1 an einem Untergrund 20 am Beispiel eines Dachaufbaus 1, der am Dachuntergrund 20 eines zugehörigen Bauwerks oder Fahrzeugs (z. B. Wohnmobil, Bus, Schiff etc.) fixiert ist. Ein derartiger Dachaufbau 1 ist beispielsweise als Solaranlage, Antenne, Satellitenempfangsanlage oder vergleichbares Anbauteil 1 ausgeführt. Zur zuverlässigen Befestigung des Dachaufbaus 1 am Dachuntergrund 20 etwa eines Gebäudes ist es wichtig, einerseits einen dauerhaften Halt zwischen Dachaufbau 1 und Dachuntergrund 20 zu gewährleisten sowie andererseits den Dachuntergrund 20 nicht unnötig negativ zu beeinflussen. Der Dachuntergrund 20 weist grundsätzlich zumindest eine gegenüber Witterungseinflüssen dichte Schicht 21 und eine Tragkonstruktion 23 auf, die der Erfüllung statischer Anforderungen dient und die wesentlichen Kräfte aufnimmt. Im einzelnen ist die Tragkonstruktion 23 vorzugsweise als Gerüststruktur, z. B. als Stahlkonstruktion, oder als Tragschale, z. B. aus Beton, ausgebildet. Die gegenüber Witterungseinflüssen dichte Schicht 21 ist im vorliegenden Ausführungsbeispiel als Dachbahn 21 aus Kunststoff ausgeführt.The figures illustrate a device for fastening an attachment 1 to a substrate 20 using the example of a roof structure 1 which is fixed to the roof substrate 20 of an associated structure or vehicle (eg motorhome, bus, ship, etc.). Such a roof structure 1 is designed for example as a solar system, antenna, satellite reception system or comparable attachment 1. For reliable attachment of the roof structure 1 on the roof substrate 20 such as a building, it is important to ensure a permanent hold between roof structure 1 and roof substrate 20 on the one hand and on the other hand, the roof substrate 20 is not unnecessarily negative influence. The roof substrate 20 basically has at least one weather-resistant layer 21 and a support structure 23, which serves to meet static requirements and absorbs the essential forces. In particular, the support structure 23 is preferably used as a scaffold structure, for. B. as a steel structure, or as a tray, z. B. made of concrete. The weather-resistant layer 21 is executed in the present embodiment as a roofing membrane 21 made of plastic.

Dies geschieht vorzugsweise mittels Kleben. Dazu weist die Kunststoffdachbahn 21 eine kaltselbstklebende Verbindungsschicht 22 auf, die an der Oberfläche der Tragkonstruktion 23 fixiert ist. Damit ist die Kunststoffdachbahn 21 ortsfest mit der Tragkonstruktion 23 verbunden. Allgemein sind aber auch andere, gleichwirkende Formen der Befestigung denkbar. Auf der Kunststoffdachbahn 21 ist wiederum das Befestigungselement 10 mittels einer Befestigungsschicht 13 verschiebesicher befestigt. Hierbei wird das Befestigungselement 10 mit der Kunststoffdachbahn 21 vorzugsweise verklebt oder verschweißt, z. B. thermisch bzw. mittels Quellschweißverfahren. Diese Befestigungsmethode ist zunächst durchdringungsfrei, so dass die witterungsbeständige Kunststoffdachbahn 21 unbeschädigt bleibt, und sorgt außerdem für eine besonders zuverlässige, unlösbare Verbindung.Figure 1 shows a first variant of the fastening device, according to which the plastic roofing membrane 21 is connected over a large area or continuously with the support structure 23. This is preferably done by gluing. For this purpose, the plastic roofing membrane 21 has a cold self-adhesive bonding layer 22, which on the surface of the Supporting structure 23 is fixed. Thus, the plastic roofing membrane 21 is fixedly connected to the support structure 23. In general, however, other equally effective forms of attachment are conceivable. On the plastic roof track 21, in turn, the fastener 10 is secured against displacement by means of a fastening layer 13. Here, the fastener 10 is preferably glued or welded to the plastic roofing membrane 21, z. B. thermally or by means of source welding. This attachment method is first penetration-free, so that the weather-resistant plastic roofing membrane 21 remains undamaged, and also ensures a particularly reliable, permanent connection.
Im einzelnen ist das Befestigungselement 10 aus thermoplastischem Kunststoff gefertigt, insbesondere auf Basis eines weichen Polyvinylchlorids PVC-P, eines Ethy- lenvinylacetats EVAC, eines flexiblen Polyoefins FPO, eines Vinylacetat-Ethylens VAE oder eines vergleichbaren Materials. Es besitzt zunächst einen plattenartigen sowie flexiblen Basisabschnitt 11 , der über die Befestigungsschicht 13 mit der Kunststoffdachbahn 21 verbunden ist. Darüber hinaus weist das Befestigungselement 10 auch einen Kern 12 auf, der gegenüber dem Basisabschnitt 11 eine höhere Festigkeit bzw. eine höhere Shorehärte besitzt. An diesem hochfesten Kern 12 ist auch zumindest ein Befestigungsmittel 14 ausgebildet, zur lösbaren Befestigung des Dachaufbaus 1. Das Befestigungsmittel 14 ist gemäß Ausführungsbeispiel nach Figur 1 als Gewindebolzen 14 gestattet, wobei der Gewindebolzen 14 in den Kern 12 eingeschraubt ist oder alternativ an diesen angeformt ist. Die spezielle Gestaltung des Befestigungselements 10 mit weichem Basisabschnitt 11 und hochfestem Kern 12 ermöglicht eine jeweils gezielte funktionale Auslegung der Einzelkomponenten. Gleichzeitig hält sich der fertigungstechnische Aufwand in Grenzen, insbesondere wenn das Befestigungselement 10 mittels Kunststoffspritztechnik vorteilhaft mit zwei unterschiedlichen Shorehärten hergestellt wird.In detail, the fastening element 10 is made of thermoplastic material, in particular based on a soft polyvinyl chloride PVC-P, an ethylene vinyl acetate EVAC, a flexible polyolefin FPO, a vinyl acetate ethylene VAE or a comparable material. It initially has a plate-like and flexible base portion 11 which is connected via the attachment layer 13 with the plastic roofing membrane 21. In addition, the fastening element 10 also has a core 12, which has a higher strength or a higher Shore hardness compared to the base portion 11. At least one fastening means 14 is also formed on this high-strength core 12, for the detachable fastening of the roof structure 1. The fastening means 14 is permitted as a threaded bolt 14 according to the embodiment of FIG. 1, wherein the threaded bolt 14 is screwed into the core 12 or alternatively is molded onto it , The special design of the fastener 10 with a soft base portion 11 and high-strength core 12 allows a targeted functional design of the individual components. At the same time, the manufacturing effort is limited, especially when the fastener 10 is advantageously made by means of plastic injection technique with two different Shore hardnesses.
Die eigentliche lösbare Befestigung des Dachaufbaus 1 bzw. des Anbauteils 1 erfolgt beispielsweise über einen mit dem Anbauteil 1 verbundenen Befestigungsbügel 2, der etwa mittels zweier Muttern 3, 4 mit dem Gewindebolzen 14 des Befestigungselements 10 verschraubt ist. Die lösbare Befestigung mittels Verschraubung bietet zudem den Vorteil, dass das Anbauteil 1 bezüglich seiner Einbauhöhe gegenüber dem Untergrund 20 eingestellt werden kann. Durch die beschriebenen Form der Befestigungsvorrichtung, insbesondere den Aufbau des Befestigungselements 10 wird eine zuverlässige Einleitung von am Anbauteil 1 angreifenden Kräften, z. B. Windkräften, in die Tragkonstruktion 23 erreicht. Vor allem geschieht die Einleitung von angreifenden Kräften ohne Schädigung der vor Witterungseinflüssen schützenden Schicht bzw. Kunststoffdachbahn 21. Hierbei verhindert der flexibel ausgebildete Basisabschnitt 11 bei einer etwaigen Krafteinwirkung ein mechanisches Eindrücken des Befestigungselements 10 in die Kunststoffdachbahn 21.The actual releasable fastening of the roof structure 1 or the attachment 1 takes place for example via a mounting bracket 2 connected to the attachment 1, which is screwed about by means of two nuts 3, 4 with the threaded bolt 14 of the fastener 10. The detachable attachment by means of screwing also offers the advantage that the attachment 1 can be adjusted with respect to its installation height relative to the substrate 20. Due to the described shape of the fastening device, in particular the structure of the fastening element 10, a reliable introduction of forces acting on the attachment 1, z. As wind forces, achieved in the support structure 23. Above all, the initiation of attacking forces occurs without damaging the weather-protective layer or plastic roofing membrane 21. In this case, the flexibly formed base section 11 prevents mechanical engagement of the fastening element 10 in the plastic roofing membrane 21 in the event of a force being applied.
Figur 2 zeigt demgegenüber ein leicht abgewandeltes zweites Ausführungsbeispiel der Befestigungsvorrichtung. Zunächst umfasst der Untergrund 20 lediglich die Tragkonstruktion 23 sowie die bereits erwähnte Kunststoffdachbahn 21. Hierbei ist die Kunststoffdachbahn 21 nicht großflächig mit der Tragkonstruktion 23 verbunden sondern nur lose auf dieser verlegt. Dies erschwert natürlich die Einleitung von am Befestigungselement 10 angreifenden Kräften in die Tragkonstruktion 23. Grundsätzlich ist das Befestigungselement 10 wie bereits anhand des ersten Ausführungsbeispiels beschrieben mittels einer Befestigungsschicht 13 ortsfest an der Kunststoffdachbahn 21 fixiert, vorzugsweise durch Kleben oder Schweißen. Zumindest unterhalb des Befestigungselements 10 ist zwischen der Tragkonstruktion 23 und der lose darauf verlegten Kunststoffdachbahn 21 ein plattenförmiger Halter 5 angeordnet. Dieser Halter 5 ist einerseits über angeformte Befestigungsbolzen 6 ortsfest in der Tragkonstruktion 23 verankert und andererseits verschiebesicher mit der Kunststoffdachbahn 21 verbunden, z. B. durch Kleben, Schweißen oder vergleichbares. Auf diesem Wege können am Befestigungselement 10 auftretende Kräfte, die z. B. von Krafteinwirkungen am Anbauteil 1 herrühren, zuverlässig über die Kunststoffdachbahn 21 sowie den Halter 5 sicher in die Tragkonstruktion 23 eingeleitet werden. Generell kann ein derartiger Halter 5 nicht nur bei lose verlegten Kunststoffdachbahn 21 Anwendung finden sondern auch bei großflächig verklebten Kunststoffdachbahn 21 gemäß dem ersten Ausführungsbeispiel nach Figur 1. Auch für eine solche Variante unterstützt der Halter 5 die Kraftübertragung vor allem von Schwerkräften, insbesondere wenn die Haltbarkeit der Klebeverbindung nicht für eine dauerhafte Übertragung solch hoher Kräfte ausgelegt ist.In contrast, FIG. 2 shows a slightly modified second exemplary embodiment of the fastening device. First, the substrate 20 comprises only the support structure 23 and the aforementioned plastic roof track 21. Here, the plastic roofing membrane 21 is not a large area connected to the support structure 23 but only loosely laid on this. This, of course, complicates the introduction of forces acting on the fastening element 10 into the supporting structure 23. Basically, the fastening element 10 is fixed to the plastic roofing track 21 by means of a fastening layer 13, as already described with reference to the first exemplary embodiment, preferably by gluing or welding. At least below the fastening element 10, a plate-shaped holder 5 is arranged between the support structure 23 and the loose plastic roofing track 21 laid thereon. This holder 5 is anchored on the one hand via molded mounting bolts 6 fixed in the support structure 23 and on the other hand verschiebesicher connected to the plastic roofing membrane 21, z. B. by gluing, welding or similar. In this way, occurring on the fastener 10 forces z. B. of force effects on the attachment 1, reliable on the plastic roof track 21 and the holder 5 are securely introduced into the support structure 23. In general, such a holder 5 can be found not only in loosely laid plastic roofing membrane 21 application but also for large-area glued plastic roofing membrane 21 according to the first embodiment of Figure 1. Also for such a variant, the holder 5 supports the power transmission, especially of gravitational forces, especially if the durability of the adhesive bond is not designed for a permanent transmission of such high forces.
Darüber hinaus unterscheidet sich das zweite Ausführungsbeispiel nach Figur 2 in der Gestaltung des Befestigungsmittels 15. Dabei ist das im hochfesten Kern 12 des Befestigungselements 10 angeformte bzw. angeordnete Befestigungsmittel 15 als Buchse 15, vorzugsweise als Gewindebuchse 15, ausgebildet. An der Buchse 15 bzw. der Gewindebuchse 15 kann dann ein zugehöriges Befestigungsbauteil des Dachaufbaus 1oder des Anbauteils 1 lösbar befestigt werden, z. B. durch Verschrau- ben, Verklemmen etc.. Selbstverständlich ist man in der Wahl eines geeigneten Befestigungsmittels 14, 15 nicht auf die in den Ausführungsbeispielen gezeigten Varianten beschränkt. Es sind genauso gut auch andere, vergleichbare Befestigungsmittel denkbar, die ebenfalls eine lösbare Befestigung des Anbauteils 1 am Untergrund 20 zulassen.In addition, the second embodiment differs from Figure 2 in the design of the fastener 15. In the high-strength core 12 of the fastener 10 integrally formed or arranged fastener 15 as a bushing 15, preferably as a threaded bushing 15 is formed. At the socket 15 and the threaded bushing 15, an associated fastening component of the roof structure 1oder the attachment 1 can then be releasably attached, for. For example, by screwing, jamming, etc. Of course, the choice of a suitable fastening means 14, 15 is not limited to the variants shown in the exemplary embodiments. There are just as well conceivable other comparable fastening means, which also allow a releasable attachment of the attachment 1 to the substrate 20.
Allgemein ist die erfindungsgemäße Befestigungsvorrichtung ebenso nicht auf die anhand der Ausführungsbeispiele erläuterten Dachanwendungen begrenzt. Zunächst lassen derartige Befestigungselemente 10 auch an einem Wand-, Boden- oder sonstigen Untergrund einsetzen. Insbesondere spielt es für die Realisierung der Erfindung keine Rolle, ob der Untergrund 20 an einem unbeweglichen Bauwerk oder an einem beweglichen Objekt, vor allem an einem Fahrzeug (z. B. Bus, Wohnmobil, Kraftfahrzeug, Schiff oder ähnlichem) gemeint ist. Ferner kann auch der spezifische Aufbau des Untergrunds 20, auf dem ein erfindungsgemäßes Befestigungselement 10 zum Einsatz kommt variieren. Insbesondere kann der Untergrund 20 neben der Tragkonstruktion 23, der witterungsdichten Schicht 21 und ggf. dem Halter 5 noch weitere Komponenten aufweisen. Beispielsweise besitzen vor allem moderne Flachdachkonstruktionen zwischen der witterungsdichten Schicht 21 und der Tragkonstruktion 23 noch weitere Schichten, z. B. Dämmschicht, Dampfsperrenschicht etc.. Entscheidend hierbei ist bei allen Varianten die Übertragung von am Anbauteil angreifenden Kräften über das Befestigungselement 10 in die Tragkonstruktion 23. Schließlich umfasst die Erfindung jegliche Art eines Anbauteils 1 , welches sich mit der der gattungsgemäßen Befestigungsvorrichtung an einem oben beschriebenen Untergrund fixieren lässt, und damit nicht nur die konkret genannten Dachaufbauteile (z. B. Solaranlagen, Antennen, Satellitenempfangsanlagen etc.) sondern ebenso vergleichbare sonstige Anbauteile 1. In general, the fastening device according to the invention is likewise not limited to the roof applications explained with reference to the exemplary embodiments. First of all, such fastening elements 10 can also be used on a wall, floor or other substrate. In particular, it is irrelevant to the realization of the invention whether the substrate 20 is intended for an immovable building or for a movable object, in particular for a vehicle (eg bus, camper, motor vehicle, ship or the like). Furthermore, the specific structure of the substrate 20 on which a fastening element 10 according to the invention is used can also vary. In particular, the substrate 20 in addition to the support structure 23, the weather-tight layer 21 and possibly the holder 5 may have further components. For example, especially modern flat roof constructions have between the weather-resistant layer 21 and the supporting structure 23 even more layers, z. The decisive factor here is in all variants, the transmission of forces acting on the attachment forces on the fastener 10 in the support structure 23. Finally, the invention includes any type of attachment 1, which with the generic fastening device at an above and thus not only the specifically mentioned roof construction parts (eg solar systems, antennas, satellite reception systems etc.) but also comparable other attachments 1.
