Description
Die Erfindung betrifft eine mehrteilig ausgebildete Haltevorrichtung zum Anbringen plattenförmiger Wand- oder Deckenbekleidungselemente an einem bauseitigen Untergrund mit den Merkmalen des Oberbegriffs des Anspruchs 1. Des Weiteren betrifft die Erfindung ein Verfahren zur Herstellung einer solchen Haltevorrichtung.The invention relates to a multi-part holding device for attaching plate-shaped wall or ceiling clothing elements to an on-site substrate with the features of the preamble of claim 1. Furthermore, the invention relates to a method for producing such a holding device.
Haltevorrichtungen der vorstehend genannten Art können insbesondere zur Ausbildung vorgehängter, hinterlüfteter Fassaden eingesetzt werden. Hierbei werden plattenförmige Fassadenelemente unter Zuhilfenahme der Haltevorrichtung vor eine tragende Wandkonstruktion gehängt, die in der Regel außenseitig gedämmt ist. Da die Haltevorrichtung jedoch aus statischen Gründen an der tragenden Wandkonstruktion zu befestigen ist, muss zumindest der durch die Dämmschicht geschaffene Abstand zwischen der tragenden Wandkonstruktion und den plattenförmigen Fassadenelementen mittels der Haltevorrichtung überbrückt werden. Je nach Dämmschichtdicke, die es zu überbrücken gilt, kann die Ausladung der Haltevorrichtung beträchtlich sein. Ist aus bauphysikalischen Gründen ferner eine Hinterlüftung der Fassade gefordert, vergrößert sich der Abstand bzw. die Ausladung der Haltevorrichtung um eine zwischen der Dämmschicht und den plattenförmigen Fassadenelementen angeordnete, durchgehende Luftschicht.Holding devices of the aforementioned type can be used in particular for the formation of curtain-type, ventilated facades. Here, plate-shaped facade elements are hung with the aid of the holding device in front of a load-bearing wall construction, which is usually insulated on the outside. However, since the holding device is to be attached to the load-bearing wall construction for static reasons, at least the distance created by the insulating layer between the supporting wall construction and the plate-shaped facade elements must be bridged by means of the holding device. Depending on the Dämmschichtdicke, which is to be bridged, the projection of the holding device can be considerable. If a rear ventilation of the façade is also required for structural-physical reasons, the distance or the projection of the holding device increases by a continuous air layer arranged between the insulating layer and the plate-shaped facade elements.
Da das Hebelgesetz anwendbar ist, steigt mit zunehmendem Abstand bzw. mit zunehmender Ausladung der Haltevorrichtung auch deren Belastung. Sollen zudem besonders schwere Fassadenelemente, beispielsweise solche aus Naturstein oder Glas, an einem bauseitigen Untergrund angebracht werden, muss die Haltevorrichtung eine ausreichende mechanische Stabilität besitzen, um die Lastabtragung in den Untergrund zu gewährleisten.Since the lever law is applicable, the load increases with increasing distance or with increasing projection of the holding device. Should also Particularly heavy facade elements, such as those made of natural stone or glass, are attached to an on-site support, the fixture must have sufficient mechanical stability to ensure the load transfer into the ground.

Sie umfasst ein am Untergrund befestigbares Basisteil sowie mindestens ein mit dem Basisteil verbindbares Auslegerteil. Über das Auslegerteil ist die Haltevorrichtung mit einem Halteprofil verbindbar, das der Aufnahme mindestens eines plattenförmigen Wand- oder Deckenbekleidungselements dient. Das Basisteil weist eine längliche Basisplatte und mindestens einen senkrecht hierzu stehenden Schenkel zur Verbindung des Basisteils mit dem Auslegerteil auf. Erfindungsgemäß ist der Schenkel gegenüber einer ersten und einer zweiten Längskante der Basisplatte jeweils nach innen versetzt angeordnet. Das heißt, dass das Basisteil in einer Seitenansicht nicht L-förmig, sondern zumindest annähernd T-förmig ausgebildet ist. Die nach innen versetzte Anordnung des Schenkels ermöglicht eine im Wesentlichen mittige Belastung des Basisteils, wenn das Auslegerteil mit dem Schenkel des Basisteils verbunden wird. Auf diese Weise erhöht sich die Belastbarkeit der Haltevorrichtung. Dies gilt insbesondere, wenn die Befestigung des Basisteils am Untergrund in gedachter Verlängerung des Schenkels bzw. in einer Flucht mit dem Schenkel erfolgt. Beispielsweise kann die Befestigung am Untergrund mittels Schrauben und/oder Dübel bewirkt werden, die dann vorzugsweise derart angeordnet werden, dass sie auf einer Achse mit dem Schenkel zu liegen kommen.The proposed for attaching plate-shaped wall or ceiling clothing elements on an on-site support holding device is designed in several parts. It comprises a base part which can be fastened to the substrate and at least one boom part which can be connected to the base part. About the boom part, the holding device can be connected to a holding profile, which serves to receive at least one plate-shaped wall or ceiling lining element. The base part has an elongated base plate and at least one leg perpendicular thereto for connecting the base part to the boom part. According to the invention, the leg is arranged offset in each case inwards relative to a first and a second longitudinal edge of the base plate. That is, the base part in a side view is not L-shaped, but at least approximately T-shaped. The inwardly offset arrangement of the leg allows a substantially central loading of the base part when the boom part is connected to the leg of the base part. In this way, the load capacity of the holding device increases. This is especially true if the attachment of the base part takes place on the ground in imaginary extension of the leg or in alignment with the leg. For example, the attachment to the ground can be effected by means of screws and / or dowels, which are then preferably arranged so that they come to lie on an axis with the leg.
Über die längliche Basisplatte vermag sich das Basisteil am Untergrund abzustützen. Bevorzugt wird das Basisteil bei der Befestigung am Untergrund in der Weise orientiert, dass die Längsachse der Basisplatte mit der Hauptbelastungsrichtung zusammenfällt. An einer Wand erfolgt die Befestigung daher bevorzugt hochkant. Die gleiche Ausrichtung erfährt dabei der Schenkel, der vorzugsweise parallel zurAbout the elongated base plate, the base part is able to support the ground. Preferably, the base part is oriented in the attachment to the ground in such a way that the longitudinal axis of the base plate coincides with the main loading direction. On a wall, the attachment is therefore preferably edgewise. The same orientation undergoes the leg, which is preferably parallel to
Längsachse der Basisplatte und/oder parallel zu mindestens einer Längskante der Basisplatte verläuft. Auf diese Weise wird eine hohe Formsteifigkeit des Basisteils in Belastungsrichtung erreicht.Longitudinal axis of the base plate and / or runs parallel to at least one longitudinal edge of the base plate. In this way, a high dimensional stability of the base part in the loading direction is achieved.
Um das Auslegerteil mit dem Basisteil zu verbinden, wird dieses bevorzugt flach an eine Seitenfläche des Schenkels des Basisteils angelegt. Die eigentliche Verbindung kann wiederum mittels mechanischer Befestigungs- bzw. Verbindungsmittel, wie beispielsweise Schrauben, Nieten, Bolzen oder dergleichen, bewirkt werden. Das Auslegerteil kommt somit ebenfalls hochkant zu liegen, so dass die Lastabtragung über die gesamte Höhe des Auslegerteils erfolgt, was sich ebenfalls positiv auf die Belastbarkeit der Haltevorrichtung auswirkt.In order to connect the cantilever part to the base part, this is preferably applied flat to a side surface of the leg of the base part. The actual connection can in turn be effected by means of mechanical fastening or connecting means, such as screws, rivets, bolts or the like. The boom part thus comes also upright, so that the load transfer over the entire height of the jib part takes place, which also has a positive effect on the load capacity of the holding device.
Die mehrteilige Ausführung der Haltevorrichtung ermöglicht die Verwendung unterschiedlich langer Auslegerteile, so dass eine hohe Variabilität erreichbar ist, da je nach Länge des Auslegerteils unterschiedliche Abstände bzw. Ausladungen der Haltevorrichtung realisierbar sind.The multi-part design of the holding device allows the use of different length boom parts, so that a high variability can be achieved, since depending on the length of the boom part different distances or projections of the holding device can be realized.
Gemäß einer bevorzugten Ausführungsform der Erfindung begrenzt der Schenkel eine in der Basisplatte des Basisteils ausgebildete Aussparung, die sich vom Schenkel bis zu einer ersten Längskante der Basisplatte erstreckt. Durch diese Ausgestaltung kann die Herstellung des Basisteils und damit der Haltevorrichtung vereinfacht werden. Denn bei der Herstellung der Aussparung kann das überschüssige Material zur Ausbildung des Schenkels genutzt werden. Beispielsweise kann die Basisplatte im Bereich der ersten Längskante zweifach geschlitzt werden, so dass eine Lasche freigelegt wird, die zur Ausbildung des Schenkels nur noch durch Biegen in eine im Wesentlichen senkrecht zur Basisplatte stehende Position gebracht werden muss.According to a preferred embodiment of the invention, the leg defines a recess formed in the base plate of the base part and extending from the leg to a first longitudinal edge of the base plate. With this configuration, the production of the base part and thus the holding device can be simplified. Because in the production of the recess, the excess material can be used to form the leg. For example, the base plate can be slotted twice in the region of the first longitudinal edge, so that a tab is exposed, which only has to be brought by bending into a standing substantially perpendicular to the base plate position for the formation of the leg.
Bevorzugt ist daher zumindest das Basisteil der erfindungsgemäßen Haltevorrichtung ein Stanz-/Biegeteil, da es sich als solches einfach und kostengünstig herstellen lässt. Ferner bevorzugt ist zumindest das Basisteil aus Metall gefertigt. Durch die Verwendung eines metallischen Werkstoffs kann die Robustheit des Basisteils gesteigert werden.Preferably, therefore, at least the base part of the holding device according to the invention is a stamped / bent part, since it can be produced as such simple and inexpensive. Further preferably, at least the base part is made of metal. By using a metallic material, the robustness of the base part can be increased.
Des Weiteren bevorzugt ist zumindest das Basisteil aus Edelstahl gefertigt. Edelstahl korrodiert nicht und ist demnach insbesondere für den Einsatz im Außenbereich, vorzugsweise im Fassadenbereich, geeignet. Zugleich weist Edelstahl eine hohe Festigkeit auf, so dass das Basisteil hohe Lasten aufzunehmen vermag.Furthermore, preferably at least the base part is made of stainless steel. Stainless steel does not corrode and is therefore particularly suitable for outdoor use, preferably in the façade area. At the same time stainless steel has a high strength, so that the base part is able to absorb high loads.
Zur Robustheitssteigerung der gesamten Haltevorrichtung wird vorgeschlagen, dass auch das Auslegerteil vorzugsweise aus einem metallischen Werkstoff, insbesondere aus Edelstahl, gefertigt ist. Auf diese Weise wird zugleich eine hohe Festigkeit bzw. Formsteifigkeit der Haltevorrichtung erreicht.To increase the robustness of the entire holding device, it is proposed that the jib part is preferably made of a metallic material, in particular of stainless steel. In this way, a high strength or dimensional stability of the holding device is achieved at the same time.
Vorteilhafterweise ist der Schenkel des Basisteils im Wesentlichen mittig in Bezug auf die Breite der Basisplatte angeordnet. Die mittige Anordnung sorgt für eine gleichmäßige Lastverteilung. Dies gilt insbesondere, wenn auch die zur Befestigung des Basisteils am Untergrund vorgesehenen Befestigungsmittel im Wesentlichen mittig in Bezug auf die Breite der Basisplatte angeordnet werden, so dass diese auf einer Achse mit dem Schenkel zu liegen kommen.Advantageously, the leg of the base part is arranged substantially centrally with respect to the width of the base plate. The central arrangement ensures an even load distribution. This applies in particular if the fastening means provided for fastening the base part to the substrate are arranged substantially centrally with respect to the width of the base plate, so that they come to lie on an axis with the leg.
Zur Aufnahme eines Befestigungsmittels, mittels dessen das Basisteil am Untergrund befestigbar ist, weist die Basisplatte bevorzugt mindestens eine Ausnehmung auf. Die Ausnehmung kann insbesondere in Form einer Bohrung und/oder eines Langlochs ausgebildet sein. Als Befestigungsmittel können beispielsweise Schrauben und/oder Dübel dienen. Um die Belastbarkeit der Haltevorrichtung zu optimieren, wird ferner vorgeschlagen, dass die mindestens eine Ausnehmung mittig in Bezug auf die Breite der Basisplatte angeordnet ist. Die Belastbarkeit wird insbesondere dann optimiert, wenn der Schenkel - wie zuvor beschrieben - ebenfalls mittig in Bezug auf die Breite der Basisplatte angeordnet ist, so dass die Befestigungsmittel auf einer Achse mit dem Schenkel liegen.For receiving a fastening means, by means of which the base part can be fastened to the substrate, the base plate preferably has at least one recess. The recess may be formed in particular in the form of a bore and / or a slot. As fastening means, for example screws and / or dowels can serve. In order to optimize the load capacity of the holding device, it is further proposed that the at least one recess is arranged centrally with respect to the width of the base plate. The load capacity is optimized in particular when the leg - as described above - also in the middle in With respect to the width of the base plate is arranged, so that the fastening means lie on an axis with the leg.
In Weiterbildung der Erfindung wird vorgeschlagen, dass die Basisplatte im Bereich der zweiten Längskante eine Aufkantung aufweist. Die Aufkantung bewirkt eine Aussteifung, so dass sich durch diese Maßnahme die Formsteifigkeit des Basisteils erhöht. Vorzugsweise erstreckt sich die Aufkantung über die gesamte Länge der zweiten Längskante.In a further development of the invention, it is proposed that the base plate has an upstand in the region of the second longitudinal edge. The upstand causes a stiffening, so that increases the dimensional stability of the base part by this measure. Preferably, the upstand extends over the entire length of the second longitudinal edge.
Weiterhin bevorzugt weist der Schenkel des Basisteils mindestens eine Ausnehmung zur Aufnahme eines Verbindungsmittels auf, mittels dessen das Auslegerteil mit dem Basisteil verbindbar ist. Als Verbindungsmittel kann mindestens eine Schraube, ein Bolzen, ein Niet oder dergleichen eingesetzt werden. Die Ausnehmung kann insbesondere als Bohrung und/oder als Langloch ausgebildet sein. Eine als Langloch ausgebildete Ausnehmung besitzt den Vorteil, dass die zu verbindenden Teile relativ zueinander verschiebbar sind, um beispielsweise Fertigungs- und/oder Montagetoleranzen auszugleichen. Alternativ oder ergänzend wird vorgeschlagen, dass mehrere Ausnehmungen in gereihter Anordnung vorgesehen sind, so dass über die Wahl der Ausnehmung unterschiedliche Abstände des Auslegerteils in Bezug auf den Untergrund realisierbar sind.Further preferably, the leg of the base part has at least one recess for receiving a connecting means, by means of which the cantilever part can be connected to the base part. As a connecting means, at least one screw, a bolt, a rivet or the like can be used. The recess may be formed in particular as a bore and / or as a slot. A recess formed as an elongated hole has the advantage that the parts to be joined are displaceable relative to each other, for example, to compensate for manufacturing and / or assembly tolerances. Alternatively or additionally, it is proposed that a plurality of recesses are provided in a row arrangement, so that different distances of the jib part with respect to the ground can be realized via the choice of the recess.
Bevorzugt weist das Basisteil zwei in Längsrichtung zueinander beabstandete Schenkel auf, mittels welcher das Basisteil mit dem Auslegerteil verbindbar ist. Durch diese Maßnahme kann der Kontaktbereich des Auslegerteils mit dem Basisteil reduziert werden, was eine verminderte Wärmeübertragung zur Folge hat. Die Stabilität der Haltevorrichtung wird nicht oder zumindest nicht wesentlich beeinträchtigt, wenn die beiden Schenkel einschließlich Abstand eine Gesamtbreite aufweisen, die zumindest annähernd der Breite des Auslegerteils entspricht.Preferably, the base part has two legs spaced apart in the longitudinal direction, by means of which the base part can be connected to the boom part. By this measure, the contact area of the jib part can be reduced with the base part, resulting in a reduced heat transfer result. The stability of the holding device is not or at least not substantially impaired if the two legs including the distance have a total width which corresponds at least approximately to the width of the jib part.
Ferner bevorzugt weist das Auslegerteil mindestens eine Ausnehmung, insbesondere in Form einer Bohrung und/oder eines Langlochs, zur Aufnahme eines Verbindungsmittels auf, mittels dessen das Auslegerteil mit dem Basisteil und/oder mit einem Halteprofil verbindbar ist. Die Ausnehmung bzw. Ausnehmungen sind daher bevorzugt in zumindest einem Endabschnitt des Auslegerteils vorgesehen, der zur Anlage am Basisteil bzw. in Kontakt mit dem Halteprofil gelangt. Die Anordnung der Ausnehmung bzw. Ausnehmungen erfolgt bevorzugt in der Weise, dass sie jeweils in Überdeckung mit einer Ausnehmung des Schenkels des Basisteils bringbar sind.Further preferably, the jib part has at least one recess, in particular in the form of a bore and / or a slot, for receiving a connection means by means of which the jib part can be connected to the base part and / or to a retaining profile. The recess or recesses are therefore preferably provided in at least one end portion of the cantilever part, which comes to rest on the base part or in contact with the holding profile. The arrangement of the recess or recesses is preferably carried out in such a way that they can be brought into coincidence with a recess of the leg of the base part.
Darüber hinaus wird vorgeschlagen, dass das Auslegerteil in zumindest einem Endabschnitt eine Aussparung zur Freistellung laschenartiger Abschnitte aufweist, über welche das Auslegerteil mit dem Basisteil und/oder dem Halteprofil verbindbar ist. Die Aussparung reduziert den Kontaktbereich des Auslegerteils mit dem Basisteil bzw. dem Halteprofil, so dass die Wärmeübertragung reduziert wird. Die Stabilität der Haltevorrichtung wird durch diese Maßnahme nicht oder nicht wesentlich beeinträchtigt, wenn die Gesamtbreite der laschenartigen Abschnitte einschließlich Aussparung im Wesentlichen der Breite des Auslegerteils entspricht.In addition, it is proposed that the boom part in at least one end portion has a recess for releasing tab-like portions, via which the boom part with the base part and / or the retaining profile is connectable. The recess reduces the contact area of the cantilever part with the base part or the retaining profile, so that the heat transfer is reduced. The stability of the holding device is not or not substantially affected by this measure, if the total width of the tab-like sections including recess substantially corresponds to the width of the jib part.
In Weiterbildung der Erfindung wird vorgeschlagen, dass das Auslegerteil mindestens eine in der Fläche angeordnete Aussparung aufweist. Durch die mindestens eine in der Fläche angeordnete Aussparung kann der Wärmeabfluss über das Auslegerteil reduziert werden. Auf diese Weise lassen sich Haltevorrichtungen realisieren, die passivhaustauglich sind. Ähnlich einem Fachwerkträger wird die Belastbarkeit des Auslegerteils durch die mindestens eine in der Fläche angeordnete Aussparung nicht beeinträchtigt. Zugleich kann Material und damit Gewicht eingespart werden.In a further development of the invention, it is proposed that the jib part has at least one recess arranged in the surface. By the at least one recess arranged in the surface of the heat flow can be reduced via the boom part. In this way, holding devices can be realized which are passivhaustauglich. Similar to a truss girder, the load capacity of the jib part is not impaired by the at least one recess arranged in the surface. At the same time material and thus weight can be saved.
Alternativ oder ergänzend wird vorgeschlagen, dass die Haltevorrichtung mindestens einen Dämmstoffstreifen zur Realisierung einer thermischen Trennung des Basisteils vom bauseitigen Untergrund umfasst. Bei der Montage der Haltevorrichtung am Untergrund kann der Dämmstoffstreifen unter das Basisteil gelegt werden, um eine thermische Trennung zu realisieren. Alternativ kann der Dämmstoffstreifen bereits werkseits am Basisteil befestigt sein, so dass ein Arbeitsschritt an der Baustelle entfällt. Vorzugsweise ist der Dämmstoffstreifen aus gesintertem Polystyrol gefertigt, das auch in geringen Stärken gute Wärmedämmwerte besitzt und zudem ausreichend formstabil ist, um die Haltevorrichtung am Untergrund abzustützen.Alternatively or additionally, it is proposed that the holding device has at least one insulation strip for realizing a thermal separation of the base part from the on-site background includes. When mounting the holding device to the substrate, the insulating strip can be placed under the base part in order to realize a thermal separation. Alternatively, the insulation strips can already be factory-fixed to the base part, so that a step on the site is eliminated. Preferably, the insulating strip is made of sintered polystyrene, which has good thermal insulation values even in small thicknesses and is also sufficiently dimensionally stable to support the holding device on the ground.
Um die Formsteifigkeit des Auslegerteils zu erhöhen, wird vorgeschlagen, dass das Auslegerteil mindestens einen umgeformten, insbesondere ein- oder mehrfach gekanteten oder gebördelten, Kantenbereich aufweist. Vorzugsweise sind zwei parallel zueinander liegende Kantenbereiche auf diese Weise umgeformt. Die umgeformten Kantenbereiche sind vorzugsweise derart gestaltet, dass sie den bzw. die Schenkel des Basisteils umgreifen oder hintergreifen, so dass zusätzlich eine formschlüssige Verbindung des Auslegerteils mit dem Basisteil erzielbar ist. Zum Verbinden des Auslegerteils mit dem Basisteil muss in diesem Fall das Auslegerteil auf den bzw. die Schenkel des Basisteils aufgeschoben werden. Um eine ebene Anlagefläche zur Verbindung des Auslegerteils mit einem Halteprofil zu gewährleisten, erfolgt vorzugsweise die Umformung in der Weise, dass die umgeformten Kantenbereiche jeweils auf derselben Seite des Auslegerteils zu liegen kommen.In order to increase the dimensional stability of the jib part, it is proposed that the jib part has at least one deformed, in particular one or more folded or flanged edge region. Preferably, two mutually parallel edge regions are formed in this way. The deformed edge regions are preferably designed such that they engage around or engage behind the leg (s) of the base part, so that in addition a positive connection of the jib part to the base part can be achieved. In order to connect the jib part to the base part, in this case the jib part has to be pushed onto the leg (s) of the base part. In order to ensure a flat contact surface for the connection of the jib part with a retaining profile, the forming preferably takes place in such a manner that the deformed edge regions each come to rest on the same side of the jib part.
Ferner wird ein Verfahren zur Herstellung einer erfindungsgemäßen Haltevorrichtung vorgeschlagen. Das Verfahren zeichnet sich dadurch aus, dass das Basisteil und/oder das Auslegerteil der Haltevorrichtung in einem Stanz-Biegeverfahren aus einem Metallblech, insbesondere aus einem Edelstahlblech, hergestellt wird bzw. werden. Das Verfahren ermöglicht eine besonders einfache und damit kostengünstige Herstellung der erfindungsgemäßen Haltevorrichtung.Furthermore, a method for producing a holding device according to the invention is proposed. The method is characterized in that the base part and / or the jib part of the holding device is or are produced in a punch bending method from a metal sheet, in particular from a stainless steel sheet. The method enables a particularly simple and thus cost-effective production of the holding device according to the invention.
Zur Ausbildung des mindestens einen Schenkels des Basisteils wird vorzugsweise durch Stanzen eine Lasche aus dem Metallblech freigelegt, die anschließend gebogen wird, so dass die Lasche im Wesentlichen senkrecht zur Basisplatte steht. Die Basisplatte kann während des Stanzens auf Maß gebracht werden, so dass sie eine längliche Form aufweist, deren Längsachse parallel zum Schenkel verläuft.To form the at least one leg of the base part, a tab is preferably exposed by punching from the metal sheet, which is then bent, so that the tab is substantially perpendicular to the base plate. The base plate can be made to measure during the punching so that it has an elongated shape whose longitudinal axis is parallel to the leg.
Ferner wird ein Haltesystem zum Anbringen plattenförmiger Wand- oder Deckenbekleidungselemente an einem bauseitigen Untergrund mit mindestens einer erfindungsgemäßen Haltevorrichtung und mindestens einem Halteprofil vorgeschlagen. Das Halteprofil dient der Aufnahme der plattenförmigen Wand- oder Deckenbekleidungselemente. Um die Verbindung des Halteprofils mit der erfindungsgemäßen Haltevorrichtung zu erleichtern, wird vorgeschlagen, dass das Halteprofil im Querschnitt T-förmig ausgebildet ist. Der vorzugsweise mittig angesetzte Steg des im Querschnitt T-förmigen Halteprofils kann seitlich an das Auslegerteil der Haltevorrichtung angelegt und mit diesem unter Zuhilfenahme von Verbindungsmittel, wie beispielsweise Schrauben, Bolzen oder Nieten, verbunden werden. Der endseitig am Steg angeordnete Flansch, der der Aufnahme der plattenförmigen Wand- oder Deckenelemente dient, kommt auf diese Weise parallel zum Untergrund zu liegen. Gleiches gilt entsprechend für die plattenförmigen Wand- oder Deckenelemente.Furthermore, a holding system for attaching plate-shaped wall or ceiling clothing elements to an on-site substrate with at least one holding device according to the invention and at least one holding profile is proposed. The retaining profile serves to receive the plate-shaped wall or ceiling clothing elements. In order to facilitate the connection of the holding profile with the holding device according to the invention, it is proposed that the holding profile is formed in cross-section T-shaped. The preferably centrally located web of the cross-sectionally T-shaped holding profile can be laterally applied to the jib part of the holding device and connected to this with the aid of connecting means, such as screws, bolts or rivets. The end arranged on the web flange, which serves to receive the plate-shaped wall or ceiling elements, comes to lie in this way parallel to the ground. The same applies accordingly for the plate-shaped wall or ceiling elements.
