Wandbekleidungen aus Stein oder Glas erfreuen sich einer großen Beliebtheit. Dies gilt insbesondere für den Fassadenbereich. Denn Wandbekleidungen aus Stein oder Glas sind pflegeleicht und vermitteln eine gewisse Werthaltigkeit.Wallcoverings made of stone or glass enjoy great popularity. This applies in particular to the façade area. For wallcoverings made of stone or glass are easy to clean and convey a certain value.

Allerdings ist nicht jede Wand zur Aufnahme derartiger Wandbekleidungen geeignet, da Stein- und Glasplatten ein hohes Eigengewicht haben. Die Wand muss in der Lage sein, die Lasten des Eigengewichts der Wandbekleidung und Windlasten abzutragen. Bei Wänden in Leichtbauweise, beispielsweise in Skelett-oder Ständerbauweise, ist dies nicht immer der Fall.However, not every wall is suitable for receiving such wall coverings, since stone and glass panels have a high dead weight. The wall must be able to remove the loads of the dead weight of the wall covering and wind loads. For walls in lightweight construction, for example in skeleton or stand construction, this is not always the case.

Hohe Anforderungen werden auch an die Befestigung derartiger Wandbekleidungselemente an einer Wand gestellt. Die Befestigung kann sichtbar oder nicht sichtbar erfolgen. Bei der Befestigung kommt oftmals erschwerend hinzu, dass es Dämm- und/oder Luftschichten zu überbrücken gilt, um beispielsweise eine vorgehängte hinterlüftete Fassade auszubilden. Die Befestigung kann dann nur unter Zuhilfenahme einer Unterkonstruktion aus vertikal und/oder horizontal verlaufenden Profilen erfolgen, wobei das Eigengewicht der Elemente die maximale horizontale Ausladung der Unterkonstruktion bestimmt.High demands are placed on the attachment of such wallcovering elements on a wall. The attachment can be visible or not visible. In the attachment is often aggravated, that it must be bridged insulating and / or air layers, for example, to form a curtain ventilated facade. The attachment can then be made only with the aid of a substructure of vertically and / or horizontally extending profiles, the weight of the elements determines the maximum horizontal projection of the substructure.

Eine herkömmliche massive Natursteinplatte in einer Größe von 1 m2 und in einer Stärke von 30 mm weist ein Gewicht von etwa 90 kg auf. Das Flächengewicht beträgt somit 90 kg/m2. Darüber hinaus sind Wandbekleidungselemente bekannt, die zur Reduzierung des Gewichts eine Dünnsteinplatte im Verbund mit einer "leichten" Trägerplatte umfassen. Die Trägerplatte dient der Verstärkung der Dünnsteinplatte, so dass das Verbundelement eine ausreichende Stabilität besitzt.A conventional solid natural stone slab of a size of 1 m 2 and a thickness of 30 mm has a weight of about 90 kg. The basis weight is thus 90 kg / m 2 . In addition, wallcovering elements are known, which include a thin stone plate in combination with a "light" support plate to reduce the weight. The carrier plate serves to reinforce the thin-stone plate, so that the composite element has sufficient stability.

Eine solche Dünnstein-Wandbauplatte geht beispielsweise aus der deutschen Gebrauchsmusterschrift DE 20 2013 102 188 U1 hervor. Die Dünnsteinplatte weist eine Dicke von 3 bis 10 mm auf und ist mit einer leichten Verstärkungsplatte aus Polyethylen hoher Dichte (HDPE), extrudiertem Polystyrolschaum (XPS), Polyvinylchlorid (PVC), expandiertem Polystyrol (EPS), expandiertem Polypropylen (EPP), einer Kalksteinplatte, einer Magnesiumoxidplatte oder einer Sandwichplatte mit einem Aluminium-Wabenkern verklebt. Zur weiteren Stabilisierung ist auf der Rückseite der Verstärkungsplatte eine Rahmenkonstruktion angebracht. Sie soll einer Verformung, insbesondere einer Verwerfung, der Verbundplatte entgegenwirken. An der Rahmenkonstruktion können wiederum Haken montiert sein, die der Befestigung der Wandbauplatte an einer Wand dienen.Such a thin-wall wallboard, for example, from the German utility model DE 20 2013 102 188 U1 out. The thin stone slab has a thickness of 3 to 10 mm and is provided with a lightweight high density polyethylene (HDPE), extruded polystyrene foam (XPS), polyvinylchloride (PVC), expanded polystyrene (EPS), expanded polypropylene (EPP), a limestone sheet , a magnesium oxide plate or a sandwich panel glued to an aluminum honeycomb core. To further stabilize a frame construction is attached to the back of the reinforcing plate. It is intended to counteract deformation, in particular a warp, of the composite panel. In turn, hooks can be mounted on the frame construction, which serve to fasten the wallboard to a wall.

Ausgehend von dem vorstehend genannten Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Wandbekleidungselement zur Bekleidung einer Wandfläche im Innen- oder Außenbereich, insbesondere zur Ausbildung einer vorgehängten hinterlüfteten Fassade, anzugeben, das in einfacher Weise, und zudem nicht sichtbar an einer Wand befestigbar ist. Das Wandbekleidungselement soll dabei zumindest teilweise aus Stein oder Glas bestehen können und für eine dauerhaft sichere Befestigung vorgerichtet sein.Based on the above-mentioned prior art, the present invention has the object, a wallcovering element for clothing a wall surface in the interior or exterior, in particular to form a curtain ventilated facade, specify that in a simple manner, and also not visible on a wall is fastened. The wallcovering element is intended at least partially made of stone or glass and can be prepared for a permanent secure attachment.

Zur Lösung der Aufgabe wird das Wandbekleidungselement mit den Merkmalen des Anspruchs 1 vorgeschlagen. Ferner wird ein Wandbekleidungssystem mit einem solchen Wandbekleidungselement angegeben. Vorteilhafte Weiterbildungen der Erfindung sind den jeweiligen Unteransprüchen zu entnehmen.To solve the problem, the wallcovering element is proposed with the features of claim 1. Further, a wallcovering system is given with such a wallcovering element. Advantageous developments of the invention can be found in the respective subclaims.

Offenbarung der ErfindungDisclosure of the invention

Das zur Bekleidung von Wandflächen im Innen- oder Außenbereich vorgeschlagene Wandbekleidungselement umfasst eine Trägerplatte und eine mit der Trägerplatte verbundene Deckplatte sowie eine Befestigungsvorrichtung zur Befestigung des Wandbekleidungselements an einer Wand oder an einer an der Wand befestigten Unterkonstruktion. Erfindungsgemäß umfasst die Befestigungsvorrichtung mindestens eine Hülse zur Aufnahme eines Befestigungsmittels, wobei die Hülse mit der Trägerplatte formschlüssig verbunden ist.The wall covering element proposed for cladding indoor or outdoor wall surfaces comprises a carrier plate and a cover plate connected to the carrier plate, and a fastening device for fastening the wall covering element to a wall or to a substructure fixed to the wall. According to the invention the fastening device comprises at least one sleeve for receiving a fastening means, wherein the sleeve is positively connected to the carrier plate.

Bei dem erfindungsgemäßen Wandbekleidungselement gehen die Trägerplatte und die Deckplatte einen festen Verbund ein. Das heißt, dass es sich bei dem erfindungsgemäßen Wandbekleidungselement um ein Verbundelement handelt. Die Anordnung erfolgt aufeinanderliegend, so dass die nach außen weisende Oberfläche der Deckplatte eine Vorderseite und die nach außen weisende Oberfläche der Trägerplatte eine Rückseite des Wandbekleidungselements ausbilden. Das erfindungsgemäße Wandbekleidungselement wird demnach bei der Anbringung an einer Wand in der Weise orientiert, dass die Trägerplatte hinten zu liegen kommt.In the wallcovering element according to the invention, the carrier plate and the cover plate form a solid composite. This means that the wallcovering element according to the invention is a composite element. The arrangement takes place on top of each other so that the outwardly facing surface of the cover plate forms a front side and the outwardly facing surface of the carrier plate forms a rear side of the wallcovering element. The wallcovering element according to the invention is therefore oriented when mounted on a wall in such a way that the carrier plate comes to lie behind.

Ferner weist das erfindungsgemäße Wandbekleidungselement mindestens eine Hülse als Befestigungsvorrichtung auf. Die Hülse ist mit der Trägerplatte verbunden, d. h., dass die Anordnung der Hülse in einem rückwärtigen Bereich des Wandbekleidungselements erfolgt, so dass sie nicht sichtbar ist. Die Hülse ermöglicht somit eine nicht sichtbare Befestigung des Wandbekleidungselements an einem Untergrund. Die Verbindung der Hülse mit der Trägerplatte ist zudem dergestalt, dass ein Formschluss bewirkt wird. Der Formschluss soll verhindern, dass sich die Hülse von der Trägerplatte und damit das Wandbekleidungselement vom Untergrund löst. Der Formschluss wird daher bevorzugt in einer Richtung senkrecht zur Plattenebene der Trägerplatte erzielt.Furthermore, the wallcovering element according to the invention has at least one sleeve as a fastening device. The sleeve is connected to the carrier plate, that is, that the arrangement of the sleeve takes place in a rear region of the wall covering element, so that it is not visible. The sleeve thus allows an invisible attachment of the wallcovering element to a substrate. The connection of the sleeve with the carrier plate is also such that a positive connection is effected. The positive connection is intended to prevent the sleeve from detaching from the carrier plate and thus the wallcovering element from the substrate. The positive connection is therefore preferably achieved in a direction perpendicular to the plate plane of the carrier plate.

Die in das Wandbekleidungselement integrierte Hülse dient der Aufnahme eines Befestigungsmittels, das weiterer Bestandteil der Befestigungsvorrichtung des Wandbekleidungselements sein kann. Das Befestigungsmittel kann jedoch auch bauseits vorgehalten werden oder Bestandteil eines Wandbekleidungssystems sein, auf das nachfolgend noch näher eingegangen wird.The sleeve integrated into the wallcovering element serves to receive a fastening means, which may be a further component of the fastening device of the wallcovering element. However, the fastening means can also be provided by the customer or be part of a wallcovering system, which will be discussed in more detail below.

Zur formschlüssigen Verbindung mit der Trägerplatte weist die Hülse bevorzugt mindestens eine ein- und/oder hinterschneidende Geometrie auf. Bei der Geometrie kann es sich beispielsweise um ein Außengewinde handeln. Die Hülse ist dann zumindest abschnittsweise in die Trägerplatte eingeschraubt. Beim Einschrauben schneidet das Außengewinde der Hülse in die Trägerplatte ein, so dass der geforderte Formschluss bewirkt wird. Alternativ oder ergänzend kann die Geometrie ein Bund sein, der ring- oder scheibenförmig ausgeführt ist. Ist der Bund an einem stirnseitigen Ende der Hülse ausgeführt, kann dieser auch durch eine mit der Hülse verbundene Kopfplatte ausgebildet werden. Über den Bund kann eine Abstützung der Hülse an einer Oberfläche der Trägerplatte bewirkt werden, wobei es sich vorzugsweise um die der Deckplatte zugewandte bzw. die mit der Deckplatte verbundene Oberfläche der Trägerplatte handelt. Das heißt, dass vorzugsweise die Hülse bei der Herstellung des Wandbekleidungselements in die Trägerplatte eingesetzt wird, bevor diese mit der Deckplatte verbunden wird.For positive connection with the carrier plate, the sleeve preferably has at least one on and / or undercut geometry. The geometry may, for example, be an external thread. The sleeve is then at least partially screwed into the carrier plate. When screwing the external thread of the sleeve cuts into the support plate, so that the required positive engagement is effected. Alternatively or additionally, the geometry may be a collar that is designed ring-shaped or disc-shaped. If the collar is designed at a front end of the sleeve, this can also be formed by a head plate connected to the sleeve. Over the collar, a support of the sleeve can be effected on a surface of the support plate, which is preferably the surface of the support plate facing the cover plate or connected to the cover plate. That is, preferably, the sleeve is used in the manufacture of the wallcovering element in the support plate before it is connected to the cover plate.

Ferner wird vorgeschlagen, dass in der Trägerplatte eine Ausnehmung ausgebildet ist, in welcher die Hülse aufgenommen ist. Die Ausnehmung ist vorzugsweise als Sackloch- oder Durchgangsbohrung ausgeführt. Wird beispielsweise der Formschluss zwischen der Hülse und der Trägerplatte über einen die Trägerplatte hintergreifenden Bund der Hülse bewirkt, ist eine durchgehende Ausnehmung vorzusehen. Denn dann kann die Hülse derart in die Ausnehmung eingesetzt werden, dass der Bund auf der der zu bekleidenden Wandfläche abgewandten Seite der Trägerplatte zu liegen kommt, während in den die Trägerplatte durchsetzenden Hülsenabschnitt ein Befestigungsmittel eingesetzt werden kann.It is also proposed that a recess is formed in the support plate, in which the sleeve is received. The recess is preferably designed as a blind hole or through hole. For example, the Form fit between the sleeve and the support plate via a carrier plate engages behind the federal government of the sleeve causes a continuous recess is provided. Because then, the sleeve can be inserted into the recess such that the collar comes to rest on the side facing away from the panel to be dressed side of the support plate, while in the carrier plate passing through the sleeve portion, a fastening means can be used.

Vorzugsweise ist die Hülse vollständig in der Trägerplatte aufgenommen. Zumindest sollte die Hülse flächenbündig in Bezug auf mindestens eine Oberfläche in die Trägerplatte eingesetzt sein. Dies gilt insbesondere im Hinblick auf die der Deckplatte zugewandte Oberfläche der Trägerplatte, um einen vollflächigen Kontakt der Trägerplatte mit der Deckplatte zu gewährleisten. Alternativ kann in der Deckplatte eine Ausnehmung zur Aufnahme des überstehenden Teils der Hülse ausgebildet sein, diese erfordert jedoch einen zusätzlichen Bearbeitungsaufwand.Preferably, the sleeve is completely received in the carrier plate. At a minimum, the sleeve should be flush-mounted with respect to at least one surface in the carrier plate. This applies in particular with regard to the surface of the carrier plate facing the cover plate in order to ensure full contact of the carrier plate with the cover plate. Alternatively, a recess for receiving the protruding part of the sleeve may be formed in the cover plate, but this requires an additional processing effort.

Zur vollständigen bzw. flächenbündigen Aufnahme eines Bunds der Hülse kann die in der Trägerplatte vorgesehene Ausnehmung zur Aufnahme der Hülse an ihrer der Deckplatte zugewandten Oberfläche eine Absenkung aufweisen. Die Absenkung kann in einfacher Weise gemeinsam mit der Ausnehmung ausgebildet werden, so dass sich der Mehraufwand in Grenzen hält.For complete or flush mounting of a collar of the sleeve provided in the support plate recess for receiving the sleeve on its surface facing the cover plate may have a lowering. The lowering can be formed in a simple manner together with the recess, so that the additional effort is limited.

Die vollständige Aufnahme der Hülse in der Trägerplatte besitzt ferner den Vorteil, dass das Wandbekleidungselement planebene Oberflächen besitzt und somit besser stapelbar ist, um es beispielsweise zu lagern oder zu einer Baustelle zu transportieren.The complete inclusion of the sleeve in the support plate also has the advantage that the wallcovering element has flat surfaces and thus is better stackable, for example, to store or transport to a construction site.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Deckplatte eine Naturwerksteinplatte, eine Kunstwerksteinplatte oder eine Glasplatte. Wie eingangs bereits erwähnt, weisen derartige Materialien ein vergleichsweise hohes Gewicht auf. Im Verbund mit einer Trägerplatte kann die Stärke der Deckplatte aus Naturstein, Kunststein oder Glas jedoch reduziert werden, so dass das Gesamtgewicht des Wandbekleidungselements geringer als eine gleich starke massive Platte aus dem jeweiligen Material ist.According to a preferred embodiment of the invention, the cover plate is a natural stone slab, a piece of artificial stone or a glass plate. As already mentioned, such materials have a comparatively high weight. In combination with a carrier plate, the strength of the cover plate made of natural stone, artificial stone or glass, however, can be reduced, so that the total weight of the Wallcovering element is less than an equally strong solid plate of the respective material.

Die Deckplatte besitzt bevorzugt eine Stärke s1 zwischen 2 und 10 mm, vorzugsweise zwischen 3 und 8 mm, weiterhin vorzugsweise zwischen 4 und 6 mm. Die Stärke hängt unter anderem vom Material und/oder der Größe der Deckplatte ab. Im Verbund mit einer geeigneten Trägerplatte lassen sich auch großformatige Wandbekleidungselemente realisieren. Beispielsweise kann das Format 1,2 m x 2,4 m betragen. Bei Verwendung einer Deckplatte aus Naturstein hängt die Größe maßgeblich vom verfügbaren Format der Rohsteintafeln ab.The cover plate preferably has a thickness s 1 between 2 and 10 mm, preferably between 3 and 8 mm, more preferably between 4 and 6 mm. The strength depends, among other things, on the material and / or the size of the cover plate. In conjunction with a suitable carrier plate, it is also possible to realize large-size wallcovering elements. For example, the format can be 1.2 mx 2.4 m. When using a natural stone cover plate, the size depends largely on the available format of the rough stone panels.

Im Hinblick auf die Funktion der Trägerplatte sollte diese eine hohe Festigkeit und Formsteifigkeit aufweisen. Zugleich sollte sie leichter als die Deckplatte sein, um Gewicht einzusparen. Bevorzugt findet daher eine Trägerplatte Einsatz, die mindestens einen Leichtfüllstoff und mindestens ein anorganisches oder organisches Bindemittel enthält. Beispielsweise kann die Trägerplatte Blähglasgranulat, Perlite, insbesondere geschlossenzellige Perlite, geblähte Vermiculite, Bims, Blähton, Schaumglas, Calcium-Silikat-Hydrat, Hohlglas-Kugeln, Leichtsande und/oder Flugasche als Leichtfüllstoff enthalten. Bevorzugt ist Blähglasgranulat als Leichtfüllstoff enthalten, so dass es sich bei der Trägerplatte insbesondere um eine Blähglasgranulatplatte handeln kann. Diese ist vergleichsweise leicht und dennoch stabil. Ferner ist sie für den Außeneinsatz geeignet, da sie unempfindlich gegenüber Feuchtigkeit ist. Darüber hinaus weist eine Blähglasgranulatplatte ein vergleichbares temperaturbedingtes Dehnungsverhalten wie eine Naturwerkstein, Kunstwerkstein oder Glasplatte auf, so dass ein dauerhaft stabiler Verbund zwischen der Deckplatte und der Trägerplatte sichergestellt ist. Das in der Trägerplatte enthaltene Bindemittel kann beispielsweise Zement, Wasserglas, Epoxidharz, Polyurethan und/oder eine Dispersion sein.With regard to the function of the carrier plate, this should have a high strength and dimensional stability. At the same time, it should be lighter than the cover plate to save weight. Preferably, therefore, a carrier plate is used which contains at least one light filler and at least one inorganic or organic binder. For example, the carrier plate can contain expanded glass granules, perlites, in particular closed-cell perlites, distended vermiculites, pumice, expanded clay, foam glass, calcium silicate hydrate, hollow glass spheres, light sands and / or fly ash as light filler. Preference is given to expanded glass granules as lightweight filler, so that the carrier plate may in particular be a sheet of expanded glass granules. This is comparatively light and yet stable. Furthermore, it is suitable for outdoor use because it is insensitive to moisture. In addition, a Blähglasgranulatplatte a comparable temperature-induced expansion behavior such as a natural stone, artistic stone or glass plate, so that a permanently stable bond between the cover plate and the support plate is ensured. The binder contained in the carrier plate may be, for example, cement, water glass, epoxy resin, polyurethane and / or a dispersion.

Die Trägerplatte besitzt bevorzugt eine Stärke s2 zwischen 8 und 18 mm, vorzugsweise zwischen 10 und 16 mm, weiterhin vorzugsweise zwischen 12 und 14 mm. Die Summe s1 + s2, welche vorzugsweise der Gesamtstärke des Wandbekleidungselements entspricht, kann demnach weniger als 20 mm, vorzugsweise weniger als 18 mm, beispielsweise 16 mm betragen.The support plate preferably has a thickness s 2 between 8 and 18 mm, preferably between 10 and 16 mm, more preferably between 12 and 14 mm. The sum s 1 + s 2 , which preferably corresponds to the total thickness of the wall covering element, may accordingly be less than 20 mm, preferably less than 18 mm, for example 16 mm.

In Weiterbildung der Erfindung wird vorgeschlagen, dass die Trägerplatte mindestens eine Gewebeeinlage, beispielsweise in Form eines Glasgittergewebes, aufweist. Durch die Gewebelage erfährt die Trägerplatte eine Verstärkung.In a further development of the invention, it is proposed that the carrier plate has at least one fabric insert, for example in the form of a glass mesh fabric. Due to the fabric layer, the carrier plate undergoes a reinforcement.

Alternativ oder ergänzend kann die Trägerplatte eine Kaschierung mit einem Vlies aufweisen, wobei es sich vorzugsweise um ein strömungsdichtes Vlies handelt, das auf der der Deckplatte abgewandten Oberfläche der Trägerplatte aufkaschiert ist. Das Vlies verbessert die Handhabbarkeit der Trägerplatte. Dies gilt insbesondere, wenn es sich um ein strömungsdichtes Vlies auf einer an sich nicht strömungsdichten Blähglasgranulatplatte handelt. Denn dann kann die Blähglasgranulatplatte mittels Sauggreifern angehoben und bewegt werden.Alternatively or additionally, the support plate may have a lamination with a nonwoven, which is preferably a flow-tight nonwoven, which is laminated on the surface of the support plate facing away from the cover plate. The fleece improves the handling of the carrier plate. This is especially true when it is a flow-tight web on a per se not flow-tight Blähglasgranulatplatte. Because then the expanded glass granule plate can be lifted and moved by means of suction pads.

Bevorzugt ist das Vlies aus Glas bzw. Glasfasern und einem Bindemittel hergestellt. Glas bzw. Glasfasern sind nicht brennbar, so dass durch das aufkaschierte Vlies der Brandschutz verbessert wird. Zur weiteren Optimierung des Brandschutzes und/oder zur strömungsdichten Ausführung kann das Vlies zusätzlich beschichtet sein, wobei vorzugsweise die Beschichtung mineralische Füllstoffe und ein anorganisches oder organisches Bindemittel enthält.The fleece is preferably made of glass or glass fibers and a binder. Glass or glass fibers are not flammable, so that fire protection is improved by the laminated fleece. To further optimize the fire protection and / or the flow-tight design, the nonwoven may additionally be coated, wherein preferably the coating contains mineral fillers and an inorganic or organic binder.

Bei dem erfindungsgemäßen Wandbekleidungselement sind die Deckplatte und die Trägerplatte bevorzugt miteinander verklebt und/oder verpresst. Beispielsweise kann das Verkleben unter Druckeinwirkung erfolgen. Als Kleber kann ein anorganisch und/oder organisch gebundener Kleber eingesetzt werden. Das Bindemittel kann beispielsweise Zement, Wasserglas, Epoxidharz, Polyurethan und/oder eine Dispersion sein. Bevorzugt wird ein Zweikomponenten-Epoxy-Kleber verwendet. Beim Verkleben bzw. Verpressen der beiden Platten kann zugleich eine Kaschierung bzw. ein Vlies auf die Trägerplatte aufgebracht werden, so dass hierfür kein zusätzlicher Arbeitsschritt erforderlich ist.In the wallcovering element according to the invention, the cover plate and the carrier plate are preferably glued together and / or pressed. For example, the bonding can take place under pressure. As an adhesive, an inorganic and / or organic bonded adhesive can be used. The binder may be, for example, cement, water glass, epoxy resin, polyurethane and / or a dispersion. Preferably, a two-component epoxy adhesive is used. When gluing or pressing the two plates at the same time a lamination or a fleece are applied to the carrier plate, so that no additional step is required for this.

Sofern die in das Wandbekleidungselement integrierte Befestigungsvorrichtung eine Bundhülse ist, wird diese vor dem Verkleben und/oder Verpressen der beiden Platten in die Trägerplatte eingesetzt, so dass die Bundhülse über ihren Bund an der der Deckplatte zugewandten, ggf. mit einem Vlies kaschierten Oberfläche der Trägerplatte abgestützt ist.If the fastening device integrated in the wallcovering element is a collar sleeve, it is inserted into the carrier plate prior to the gluing and / or pressing of the two plates so that the collar sleeve, via its collar, faces the surface of the carrier plate facing the cover plate, optionally with a nonwoven is supported.

Als weiterbildende Maßnahme wird vorgeschlagen, dass die Hülse ein Innengewinde zur formschlüssigen Verbindung mit dem Außengewinde eines Befestigungsmittels aufweist. Das Befestigungsmittel kann beispielsweise eine Schraube oder ein Schraubbolzen sein. Die Schraubverbindung zwischen der Hülse und dem Befestigungsmittel stellt sicher, dass die Verbindung auf Zug beanspruchbar ist. Das Befestigungsmittel kann demnach dazu eingesetzt werden, ein Profil einer zwischen der Wand und dem Wandbekleidungselement angeordneten Unterkonstruktion an der Trägerplatte zu befestigen. Über das Profil ist dann das Wandbekleidungselement an wenigstens einem weiteren Profil der Unterkonstruktion befestigbar, beispielsweise durch Einhängen. Die Befestigung des Wandbekleidungselements an der Wand erfolgt demnach völlig unsichtbar. Zugleich ist eine dauerhaft sichere Befestigung gewährleistet.As a further education measure is proposed that the sleeve has an internal thread for positive connection with the external thread of a fastener. The fastening means may be, for example, a screw or a bolt. The screw connection between the sleeve and the fastening means ensures that the connection can be subjected to tensile stress. The fastening means can therefore be used to attach a profile of a substructure arranged between the wall and the wallcovering element to the carrier plate. The wall cladding element can then be fastened to the at least one further profile of the substructure via the profile, for example by hanging. The attachment of the wallcovering element to the wall is therefore completely invisible. At the same time a permanently secure attachment is guaranteed.

Das zur Lösung der eingangs genannten Aufgabe ferner vorgeschlagene Wandbekleidungssystem umfasst neben mindestens einem erfindungsgemäßen Wandbekleidungselement mindestens ein Befestigungsmittel. Bei dem Befestigungsmittel kann es sich insbesondere um eine Schraube handeln. In diesem Fall weist die formschlüssig mit der Trägerplatte des Wandbekleidungselements verbundene Hülse ein Innengewinde auf, so dass das als Schraube ausgebildete Befestigungselement in die Hülse eingeschraubt werden kann, um beispielsweise ein Profil an der Trägerplatte zu befestigen. Dadurch, dass das erfindungsgemäße Wandbekleidungssystem mindestens ein Befestigungsmittel umfasst, können Hülse und Befestigungsmittel genau aufeinander abgestimmt werden. In der Folge erhöht sich die Sicherheit der Befestigung.In addition to at least one wallcovering element according to the invention, the wallcovering system also proposed for achieving the object stated at the outset comprises at least one fastening means. The fastening means may in particular be a screw. In this case, the sleeve connected in a form-fitting manner to the carrier plate of the wallcovering element has an internal thread, so that the fastening element embodied as a screw can be screwed into the sleeve in order for example to fasten a profile to the carrier plate. Due to the fact that the invention Wall covering system comprises at least one fastening means sleeve and fastening means can be matched exactly. As a result, the security of the attachment increases.

In Weiterbildung des Wandbekleidungssystems wird vorgeschlagen, dass das System ferner mindestens ein Profil zur Ausbildung einer Unterkonstruktion oder zur Verbindung mit einer Unterkonstruktion umfasst. Das Profil stellt dann eine Systemkomponente dar, die das System weiter komplettiert. Vorzugsweise ist das Profil ein Metallprofil, das mit dem Befestigungsmittel an der Trägerplatte des Wandbekleidungselements befestigt oder befestigbar ist. Beispielsweise kann das Profil aus Stahl, insbesondere aus verzinktem Stahl, Edelstahl oder Aluminium gefertigt sein. Ein solches Profil ist in der Lage, hohe Lasten aufzunehmen. Dies erweist sich insbesondere als Vorteil, wenn das Wandbekleidungselement eine Deckplatte aus Naturstein, Kunststein oder Glas umfasst. Ferner können derartige Profile im Außenbereich eingesetzt werden, da sie unempfindlich gegenüber Feuchtigkeit sind.In a further development of the wallcovering system, it is proposed that the system further comprises at least one profile for forming a substructure or for connection to a substructure. The profile then represents a system component that further completes the system. Preferably, the profile is a metal profile which is fastened or attachable to the fastening plate on the support panel of the wallcovering element. For example, the profile may be made of steel, in particular of galvanized steel, stainless steel or aluminum. Such a profile is able to absorb high loads. This proves to be particularly advantageous if the wallcovering element comprises a cover plate made of natural stone, artificial stone or glass. Furthermore, such profiles can be used outdoors because they are insensitive to moisture.

Die Unterkonstruktion, die der Befestigung des Wandbekleidungselements an einer Wand dient, kann ein- oder mehrteilig ausgeführt sein. Um eine vorgehängte hinterlüftete Fassade auszubilden, muss mindestens eine Profillage vorgesehen werden, die vertikal verläuft. Zum Aufhängen der Wandbekleidungselemente ist vorzugsweise eine Profillage vorgesehen, die horizontal verläuft. Jede Profillage kann wiederum aus einem oder mehreren Profilen bestehen.The substructure, which serves to attach the wallcovering element to a wall, can be made in one or more parts. In order to form a curtain ventilated facade, at least one profile layer must be provided which is vertical. For hanging the wallcovering elements, a profile layer is preferably provided which extends horizontally. Each profile position can in turn consist of one or more profiles.

Beispielsweise kann die Befestigung der Unterkonstruktion an einer Wand über ein im Querschnitt T- oder C-förmiges Profil erfolgen, das vertikal verlaufend angeordnet wird. Das T- oder C-förmige Profil bildet dann eine erste Profillage aus. Eine zweite Profillage kann über ein zweiteiliges Profil gebildet werden, dass horizontal verläuft. Das erste Teil dient der Befestigung des zweiteiligen Profils an dem T- oder C-förmigen Profil und das zweite Teil wird mit der Trägerplatte des Wandbekleidungselements verschraubt. Hierbei kann es sich insbesondere um ein Agraffenprofil handeln, das in das erste Profil der zweiten Profillage einhängbar ist.For example, the attachment of the substructure to a wall via a cross-section T- or C-shaped profile can be done, which is arranged to extend vertically. The T- or C-shaped profile then forms a first profile position. A second profile layer can be formed over a two-part profile that runs horizontally. The first part is used to attach the two-piece profile to the T or C-shaped profile and the second part is connected to the support plate of the Wallcovering element screwed. This may in particular be an agraffing profile which can be suspended in the first profile of the second profile position.

Mit jeder weiteren Profillage nimmt die horizontale Ausladung der Unterkonstruktion zu, so dass mehrteilige Unterkonstruktionen zur Überbrückung von Dämm- und/oder Luftschichten besonders gut geeignet sind.With each further profile position, the horizontal projection of the substructure increases, so that multi-part substructures for bridging insulating and / or air layers are particularly well suited.

Eine bevorzugte Ausführungsform der Erfindung wird nachfolgend anhand der beigefügten Zeichnung näher erläutert. Diese zeigt einen Längsschnitt durch ein Wandbekleidungssystem mit einem erfindungsgemäßen Wandbekleidungselement.A preferred embodiment of the invention will be explained in more detail with reference to the accompanying drawings. This shows a longitudinal section through a wallcovering system with a wallcovering element according to the invention.

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing

Das in der Figur dargestellte Wandbekleidungssystem bildet eine vorgehängte hinterlüftete Fassade aus. Es umfasst plattenförmige Wandbekleidungselemente 1, die mittels einer mehrteilig ausgeführten Unterkonstruktion 7 an einer Wand 6 befestigt sind.The wallcovering system shown in the figure forms a curtain ventilated facade. It comprises plate-shaped wall covering elements 1, which are fastened to a wall 6 by means of a multi-part substructure 7.

Die Unterkonstruktion 7 weist hierzu ein im Querschnitt T-förmiges Tragprofil 13 auf, das an einer Wandfläche 2 der Wand 6 befestigt ist. Das Tragprofil 13 verläuft vertikal. An dem Tragprofil 13 ist ein zweiteiliges Profil 12 angebracht, das der Befestigung des Wandbekleidungselements 1 an dem Tragprofil 13 dient und horizontal verläuft. Ein erstes Teil des Profils 12 ist hierzu an dem Tragprofil 13 und ein zweites Teil des Profils 12 ist an dem Wandbekleidungselement 1 befestigt. Die Verbindung der beiden Teile des Profils 12 erfolgt über eine Steckverbindung. Diese Ausgestaltung der Unterkonstruktion 7 ermöglicht die Anbringung der Wandbekleidungselemente 1 mittels Einhängen in die Unterkonstruktion 7. Vorab muss jedoch das zweite Teil des Profils 12 an dem Wandbekleidungselement befestigt werden. Die Befestigung erfolgt rückseitig unter Zuhilfenahme eines Befestigungsmittels 9 in Form einer Schraube. Wird anschließend das Wandbekleidungselement 1 vor die Unterkonstruktion 7 gehängt, ist die Befestigung nicht mehr sichtbar. Zur Feinjustierung des Wandbekleidungselements 1 ist eine Justierschraube 14 vorgesehen, so dass das Wandbekleidungselement 1 nachträglich exakt ausgerichtet werden kann.The substructure 7 has for this purpose a cross-sectionally T-shaped support profile 13 which is fixed to a wall surface 2 of the wall 6. The support profile 13 extends vertically. On the support section 13, a two-part profile 12 is attached, which serves to attach the wall covering element 1 to the support section 13 and extends horizontally. A first part of the profile 12 is for this purpose on the support profile 13 and a second part of the profile 12 is attached to the wall covering element 1. The connection of the two parts of the profile 12 via a plug connection. This embodiment of the substructure 7 allows the attachment of the wall covering elements 1 by means of hooking into the substructure 7. However, in advance, the second part of the profile 12 must be fastened to the wall cladding element. The attachment takes place at the back with the aid of a fastening means 9 in the form of a screw. If the wallcovering element 1 is subsequently hung in front of the substructure 7, the attachment is not visible anymore. For fine adjustment of the wall covering element 1, an adjusting screw 14 is provided, so that the wall covering element 1 can subsequently be aligned exactly.

Das plattenförmige Wandbekleidungselement 1 des dargestellten Wandbekleidungssystems umfasst eine Deckplatte 4 aus einem Naturstein, die mit einer Trägerplatte 3 verklebt ist. Die Stärke s1 der Deckplatte 4 beträgt dabei nur 4 mm. Es handelt sich demnach um eine Dünnsteinplatte, die der Verstärkung bedarf. Diese Aufgabe übernimmt die Trägerplatte 3, deren Stärke s2 vorliegend 12 mm beträgt. Die Gesamtstärke sG des Wandbekleidungselements 1 beträgt demnach gerade mal 16 mm. Derart geringe Stärken sind möglich, wenn - wie vorliegend der Fall - eine Blähglasgranulatplatte als Trägerplatte 3 verwendet wird.The plate-shaped wallcovering element 1 of the illustrated wallcovering system comprises a cover plate 4 made of a natural stone, which is glued to a support plate 3. The thickness s 1 of the cover plate 4 is only 4 mm. It is therefore a thin stone plate, which requires the reinforcement. This task is performed by the carrier plate 3, whose thickness s 2 is 12 mm in the present case. The total thickness s G of the wallcovering element 1 is therefore just 16 mm. Such small thicknesses are possible if - as is the case here - a Blähglasgranulatplatte is used as a support plate 3.

Die geringen Stärken führen zwangsläufig zu einem geringen Gewicht, insbesondere zu einem geringen Flächengewicht des Wandbekleidungselements 1.The small thicknesses inevitably lead to a low weight, in particular to a low basis weight of the wallcovering element 1.

Beispielsweise hat das dargestellte Wandbekleidungselement 1 die Abmessungen 1200 mm x 2400 mm x 16 mm und wiegt etwa 60 kg. Dies entspricht einem Flächengewicht von etwa 20 kg/m2. Gegenüber einer massiven Natursteinplatte weist das dargestellte Wandbekleidungselement demnach ein deutlich reduziertes Flächengewicht auf. Dies wiederum ermöglicht große horizontale Ausladungen, so dass ausreichend starke Dämm- und Luftschichten realisierbar sind.For example, the illustrated wallcovering element 1 has the dimensions 1200 mm x 2400 mm x 16 mm and weighs about 60 kg. This corresponds to a basis weight of about 20 kg / m 2 . Compared to a solid natural stone slab, the illustrated wall covering element therefore has a significantly reduced weight per unit area. This in turn allows large horizontal projections, so that sufficiently strong insulation and air layers can be realized.

Um eine dauerhaft sichere Befestigung des Wandbekleidungselements 1 an der Wand 6 zu gewährleisten, ist bereits in das Wandbekleidungselement 1 eine Befestigungsvorrichtung 5 in Form einer Hülse 8 integriert. Die Hülse 8 ist in eine Ausnehmung 11 der Trägerplatte 3 eingesetzt, so dass eine an der Hülse 8 ausgebildete Geometrie 10 in Form eines scheibenförmigen Bunds die Trägerplatte 3 hintergreift. Zur flächenbündigen Aufnahme des Bunds weist die Trägerplatte 3 im Bereich der Ausnehmung 11 eine Absenkung auf, so dass die Deckplatte 4 planeben auf der Trägerplatte 3 aufliegen und vollflächig mit der Trägerplatte 3 verklebt werden kann. Da die Hülse 8 über den die Trägerplatte 3 hintergreifenden Bund an der der Deckplatte 4 zugewandten Oberfläche der Trägerplatte 3 abgestützt ist, kann sie sich nicht aus der Trägerplatte 3 lösen.In order to ensure a permanently secure attachment of the wallcovering element 1 to the wall 6, a fastening device 5 in the form of a sleeve 8 is already integrated into the wall covering element 1. The sleeve 8 is inserted into a recess 11 of the support plate 3, so that a formed on the sleeve 8 geometry 10 in the form of a disc-shaped collar, the support plate 3 engages behind. For flush mounting of the collar, the support plate 3 in the region of the recess 11 on a reduction, so that the cover plate 4 flat on the support plate 3 and fully bonded to the support plate 3 glued can be. Since the sleeve 8 is supported on the support plate 3 behind the engaging collar on the cover plate 4 facing surface of the support plate 3, it can not be solved from the support plate 3.
