Description

Die Erfindung betrifft einen Haltewinkel für ein Fassadensystem zur unmittelbaren oder mittelbaren Befestigung wenigstens eines im Wesentlichen plattenförmigen Wand- oder Deckenbekleidungselementes an einem bauseitigen Untergrund mit den Merkmalen des Oberbegriffes des Anspruchs 1. Des Weiteren betrifft die Erfindung eine Befestigungsvorrichtung für ein Fassadensystem mit einem solchen Haltewinkel sowie ein Fassadensystem, das eine solche Befestigungsvorrichtung umfasst.The invention relates to a bracket for a facade system for the direct or indirect attachment of at least one substantially plate-shaped wall or ceiling covering element to an on-site substrate with the features of the preamble of claim 1. Furthermore, the invention relates to a fastening device for a facade system with such a bracket and a facade system comprising such a fastening device.

Wände und/oder Decken moderner Gebäude sind in der Regel systemartig aufgebaut, um den jeweils an sie, beispielsweise als Außenwand oder Wohnungstrennwand, gestellten Anforderungen zu entsprechen. D.h., dass sie mehrere Schichten bzw. Ebenen umfassen, die unterschiedliche Funktionen erfüllen. Ein Wand- oder Deckenaufbau setzt sich somit in der Regel aus der tragenden Konstruktion, die in Massiv- oder in Skelettbauweise erstellt werden kann, sowie wenigstens einer weiteren Schicht oder Ebene zusammen, um beispielsweise bauphysikalischen Anforderungen Rechnung zu tragen und/oder der Wand bzw. Decke eine besondere Gestaltung zu verleihen. Als außenliegende Schicht oder Schale finden häufig plattenförmige Werkstoffe oder Bauelemente Einsatz, die eine flächendeckende Verkleidung einer dahinterliegenden Wärmedämmschicht oder Installationsebene ermöglichen. Diese plattenförmigen Elemente gilt es dauerhaft sicher mit der tragenden Konstruktion der jeweiligen Wand oder Decke zu verbinden.Walls and / or ceilings of modern buildings are usually constructed systemically to meet the requirements placed on each, for example, as an exterior wall or apartment partition wall. That is, they include multiple layers that perform different functions. A wall or ceiling structure is thus usually composed of the load-bearing construction, which can be created in solid or skeleton construction, and at least one other layer or level together, for example, to take account of building physics requirements and / or the wall or Ceiling to give a special design. As an outer layer or shell plate-shaped materials or components often find use, which allow a comprehensive covering of an underlying thermal insulation layer or installation level. These plate-shaped elements must be permanently securely connected to the supporting structure of the respective wall or ceiling.

Da die Anforderungen an die Wärmedämmung von Gebäuden stetig steigen, müssen zum Teil starke Wärmedämmschichten überbrückt werden. Diese können beispielsweise 10 bis 20 cm stark sein. Zudem hat aus statischen Gründen die Befestigung grundsätzlich immer an der tragenden Konstruktion der Wand oder Decke zu erfolgen. Ein Haltewinkel einer hierzu vorgesehenen Befestigungsvorrichtung hat demnach auch die Funktion eines Distanzelementes zu erfüllen, um einen ausreichenden Abstand der plattenförmigen Wand- oder Deckbekleidungselemente zur tragenden Konstruktion zu gewährleisten. Der Abstand der plattenförmigen Wand- oder Deckenbekleidungselemente ist dabei in der Regel derart zu bemessen, dass zwischen der Wärmedämmung und den plattenförmigen Wand- oder Deckenbekleidungselementen eine Luftschicht zur Ausbildung einer Hinterlüftung der Fassade verbleibt. Eine Hinterlüftung der Fassade ist aus bauphysikalischen Gründen häufig unentbehrlich.Since the requirements for the thermal insulation of buildings are constantly increasing, sometimes strong thermal insulation layers must be bridged. These can be, for example 10 to 20 cm thick. In addition, for static reasons, the attachment must always be made to the supporting structure of the wall or ceiling. A bracket of a fastening device provided for this purpose therefore has to fulfill the function of a spacer element in order to ensure a sufficient distance of the plate-shaped wall or cover clothing elements to the supporting structure. The distance between the plate-shaped wall or ceiling cladding elements is usually to be dimensioned such that between the thermal insulation and the plate-shaped wall or ceiling cladding elements remains an air layer to form a rear ventilation of the facade. Rear ventilation of the facade is often indispensable for building physics reasons.

Mit zunehmendem Abstand der plattenförmigen Wand- oder Deckenbekleidungselemente zur tragenden Konstruktion einer Wand oder Decke steigen auch die statischen Anforderungen an die Vorrichtung zur Halterung bzw. Befestigung der jeweiligen Wand- oder Deckenbekleidungselemente. Dies gilt vor allem, wenn besonders schwergewichtige Materialien, wie beispielsweise Naturstein oder Glas, als plattenförmige Wand- oder Deckenbekleidungselemente vorgesehen sind. Ein gattungsgemäßer Haltewinkel mit einem ersten Schenkel zur Befestigung an einem bauseitigen Untergrund und einem zum ersten Schenkel im Wesentlichen senkrecht angeordneten zweiten Schenkel zur Befestigung eines Halteprofils bzw. einer Tragschiene wird dabei vor allem auf Biegung beansprucht. Einfluss auf die Belastung haben das Maß der Auskragung des Haltewinkels sowie die Höhe des Gewichts der Fassadenelemente. Mit zunehmender Auskragung des Haltewinkels und/oder mit zunehmendem Gewicht der Fassadenelemente steigen auch die Anforderungen an die Formsteifigkeit des Haltewinkels.With increasing distance of the plate-shaped wall or ceiling cladding elements to the load-bearing construction of a wall or ceiling, the static requirements for the device for mounting or fastening of the respective wall or ceiling cladding elements also increase. This is especially true when particularly heavy-weight materials, such as natural stone or glass, are provided as plate-shaped wall or ceiling clothing elements. A generic bracket with a first leg for attachment to an on-site ground and a first leg substantially perpendicularly arranged second leg for fastening a retaining profile or a mounting rail is claimed mainly to bending. Influence on the load have the extent of the projection of the bracket and the height of the weight of the facade elements. With increasing projection of the bracket and / or with increasing weight of the facade elements also increase the requirements for the dimensional stability of the bracket.

Bei der Auslegung eines Wand- oder Deckensystems, insbesondere eines Fassadensystems, gilt es jedoch nicht nur bauphysikalische und/oder statische Anforderung zu erfüllen, auch gestalterische Gesichtspunkte sind zu berücksichtigen. Neben der Wahl eines geeigneten, optisch ansprechenden Materials muss die Fugeneinteilung festgelegt und dabei die Größe der plattenförmigen Wand- oder Deckenbekleidungselemente bestimmt werden. Weiterhin wirkt sich die Art der Befestigung des plattenförmigen Materials - sichtbare Befestigung oder nicht sichtbare Befestigung - auf die Gestaltung der Fassade aus. Zur Ausbildung einer nicht sichtbaren Befestigung kann der Haltewinkel beispielsweise mit weiteren Halteelementen einer Befestigungsvorrichtung in Form von Profilen, Schienen oder dergleichen verbunden werden.When designing a wall or ceiling system, in particular a façade system, it is not only structural and / or static requirement to meet, also design considerations are taken into account. In addition to the choice of a suitable, visually appealing material, the joint classification must be determined and the size of the plate-shaped wall or ceiling cladding elements must be determined. Furthermore, the type of attachment of the plate-shaped material - visible attachment or invisible attachment - affects the design of the facade. To form a non-visible attachment of the bracket can be connected, for example, with other support elements of a fastening device in the form of profiles, rails or the like.

Ein Haltewinkel der eingangs genannten Art ist beispielsweise der Druckschrift DE 298 14 855 U1 zu entnehmen. Er umfasst einen ersten Schenkel zur Befestigung an einem bauseitigen Untergrund sowie einem zum ersten Schenkel im Wesentlichen senkrecht angeordneten zweiten Schenkel zur Befestigung einer Tragschiene, die ebenfalls Bestandteil einer Tragvorrichtung von Wand- oder Deckenverkleidungen ist. Des Weiteren umfasst der Haltewinkel wenigstens eine Federzunge, die am zweiten Schenkel des Haltewinkels vorgesehen ist und mittels derer die Tragschiene klemmend am Haltewinkel befestigbar ist. Die Federzunge bzw. Klemmzunge ist als separates Bauteil ausgeführt und weist vorzugsweise ein gekröpftes Einsteckende auf, das in einer Einsteckausnehmung am zweiten Schenkel des Haltewinkels einsteckbar ist. Die erst vor Ort erfolgende Befestigung der Klemmzunge soll die Montage der Tragvorrichtung erleichtern, da zur vorläufigen Festlegung der Lage der Tragschiene die Klemmzunge beidseitig am zweiten Schenkel des Haltewinkels befestigt werden kann. Zudem sollen zusätzliche Schraub- oder Nietverbindungen zur Befestigung der Klemmzunge am Haltewinkel entbehrlich sein. Als Nachteil erweist sich jedoch, dass die Anbringung der Klemmzunge einen weiteren Arbeitsschritt erfordert. Eine vor Ort erfolgende Befestigung der Klemmzunge kann sich zudem aufgrund etwaiger Fertigungs- und/oder Montagetoleranzen als schwierig erweisen.A bracket of the type mentioned is, for example, the document DE 298 14 855 U1 refer to. It comprises a first leg for attachment to an on-site substrate and a first leg substantially perpendicularly arranged second leg for attachment of a mounting rail, which is also part of a supporting device of wall or ceiling panels. Furthermore, the bracket comprises at least one spring tongue, which is provided on the second leg of the bracket and by means of which the support rail can be fastened by clamping on the bracket. The spring tongue or clamping tongue is designed as a separate component and preferably has a cranked insertion end, which can be inserted in a Einsteckausnehmung on the second leg of the bracket. The only on-site attachment of the clamping tongue to facilitate the mounting of the support device, since the clamping tongue can be fixed on both sides on the second leg of the bracket for preliminary determination of the position of the support rail. In addition, additional screw or rivet connections for fastening the clamping tongue on the bracket should be dispensable. The disadvantage, however, proves that the attachment of the clamping tongue requires a further step. An on-site attachment of the clamping tongue can also prove to be difficult due to any manufacturing and / or assembly tolerances.

Weitere Haltewinkel sind aus DE 85 01 840 U1 und DE 78 22 761 U1 bekannt. Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Haltewinkel derart weiter zu bilden, dass sowohl die Montage des Haltewinkels am Untergrund, als auch die Montage eines weiteren Halteelementes einer Befestigungsvorrichtung für ein Fassadensystem am Haltewinkel vereinfacht wird. Zudem soll der Haltewinkel eine hohe Formsteifigkeit aufweisen, um schwere Lasten halten bzw. tragen zu können. Ferner soll er dazu beitragen bauphysikalische Anforderungen zu erfüllen.Further brackets are off DE 85 01 840 U1 and DE 78 22 761 U1 known. Object of the present invention is to further develop a generic bracket so that both the mounting of the bracket on the ground, as well as the mounting of another retaining element of a fastening device for a facade system on the bracket is simplified. In addition, the bracket should have a high stiffness to hold or carry heavy loads can. Furthermore, he should contribute to meeting building physics requirements.

Zur Lösung der Aufgabe wird ein Haltewinkel mit den Merkmalen des Anspruchs 1, eine Befestigungsvorrichtung mit den Merkmalen des Anspruchs 11 sowie ein Fassadensystem mit den Merkmalen des Anspruchs 12 vorgeschlagen. Vorteilhafte Weiterbildungen eines erfindungsgemäßen Haltewinkels werden in den Unteransprüchen angegeben.To solve the problem, a bracket with the features of claim 1, a fastening device with the features of claim 11 and a facade system with the features of claim 12 is proposed. Advantageous developments of a bracket according to the invention are specified in the subclaims.

Der vorgeschlagene Haltewinkel für ein Fassadensystem zur unmittelbaren oder mittelbaren Befestigung wenigstens eines im Wesentlichen plattenförmigen Wand- oder Deckenbekleidungselementes an einem bauseitigen Untergrund umfasst einen ersten Schenkel zur Befestigung an einem bauseitigen Untergrund und einen zum ersten Schenkel im Wesentlichen senkrecht angeordneten zweiten Schenkel zur Befestigung eines Halteprofils. Am zweiten Schenkel ist zudem wenigstens eine Federzunge vorgesehen, mittels derer das Halteprofil klemmend befestigbar ist. Erfindungsgemäß weist der Haltewinkel ferner eine Lasche auf, die zumindest über einen Teilbereich beabstandet zum zweiten Schenkel angeordnet ist und eine Einführöffnung zur Aufnahme und Führung eines Halteprofils in einer Längs- und Querrichtung begrenzt. Dabei bestimmt der Abstand der Lasche zum zweiten Schenkel die Breite der Einführöffnung und legt damit die maximale Profilstärke eines einführbaren Halteprofils fest. Indem nur ein Teilbereich der Lasche beabstandet zum zweiten Schenkel des Haltewinkels angeordnet ist, weist die Lasche einen anderen Teilbereich auf, der mit dem zweiten Schenkel verbunden ist. Bevorzugt ist die Lasche über einen Steg mit dem zweiten Schenkel verbunden. Der Steg wiederum legt die Tiefe der Einführöffnung fest, so dass der Steg bzw. die Lasche, da der Steg Bestandteil der Lasche ist, beim Einführen eines Halteprofils in die Einführöffnung einen in zwei Richtungen wirksamen Anschlag ausbildet. Hierdurch vereinfacht sich die Montage eines Fassadensystems, da der Anschlag eine genaue Positionierung des Halteprofils ermöglicht. Zum einen ist durch den Anschlag der Abstand des Halteprofils zum Untergrund festgelegt, zum anderen wird das Halteprofil in einer Querrichtung gehalten, wobei eine Verschiebung des Halteprofils in seiner Längsrichtung weiterhin möglich bleibt. In seiner Funktion als Anschlag wird die Lasche zudem von der Federzunge unterstützt, da die Klemmkraft der Federzunge ebenfalls in Querrichtung des Halteprofils wirkt.The proposed bracket for a facade system for direct or indirect attachment of at least one substantially plate-shaped wall or ceiling covering element to an on-site base comprises a first leg for attachment to an on-site substrate and a first leg substantially perpendicularly arranged second leg for attachment of a retaining profile. At least one spring tongue is provided on the second leg, by means of which the retaining profile can be fastened by clamping. According to the invention, the bracket further comprises a tab which is at least over a portion spaced from the second leg and defines an insertion opening for receiving and guiding a holding profile in a longitudinal and transverse direction. In this case, determines the distance of the tab to the second leg, the width of the insertion and thus determines the maximum profile thickness of an insertable holding profile. By only a portion of the tab spaced from the second leg of the bracket is arranged, the tab on another portion which is connected to the second leg. Preferably, the tab is connected via a web to the second leg. The web, in turn, determines the depth of the insertion opening, so that the web or tab, since the web is part of the tab, forms a stop effective in two directions when a retaining profile is introduced into the insertion opening. This simplifies the assembly of a facade system, since the stop allows accurate positioning of the retaining profile. On the one hand is determined by the stop the distance of the holding profile to the ground, on the other hand, the holding profile is held in a transverse direction, with a displacement of the holding profile in its longitudinal direction remains possible. In its function as a stop, the tab is also supported by the spring tongue, since the clamping force of the spring tongue also acts in the transverse direction of the holding profile.

Nach einer bevorzugten Ausführungsform sind die Federzunge und/oder die Lasche in einem Stanz-/Biegeverfahren aus dem zweiten Schenkel des Haltewinkels heraus geformt worden. Dies hat den Vorteil, dass eine nachträgliche Anbringung der Federzunge und/oder der Lasche am Haltewinkel in einem weiteren Arbeitsschritt entfallen kann. Zur Herstellung des Haltewinkels werden aus einem plattenförmigen Material zunächst durch Stanzen die Federzunge und/oder die Lasche frei gelegt und danach durch Biegen in ihre endgültige Form bzw. Lage gebracht. Die Freilegung der Lasche erfolgt vorzugsweise durch Stanzen einer schlitzartigen Öffnung, wobei am Ende der Öffnung eine stegartige Verbindung zwischen Lasche und Schenkel verbleibt. Durch Abkanten des zweiten Schenkels im Bereich der stegartigen Verbindung wird die Lasche schließlich ausgeformt und dabei die Einführöffnung ausgebildet.According to a preferred embodiment, the spring tongue and / or the tab have been formed in a punching / bending process from the second leg of the bracket out. This has the advantage that a subsequent attachment of the spring tongue and / or the tab on the bracket can be omitted in a further step. To produce the holding angle, the spring tongue and / or the tab are first exposed from a plate-shaped material by punching and then brought into their final shape or position by bending. The exposure of the tab is preferably carried out by punching a slot-like opening, wherein at the end of the opening a web-like connection between the tab and leg remains. By folding the second leg in the region of the web-like connection, the tab is finally formed and in the process the insertion opening is formed.

Vorzugsweise sind die Federzunge und die Lasche an sich gegenüberliegenden Seitenkanten des zweiten Schenkels angeordnet. Somit weisen Federzunge und Lasche einen Abstand zueinander auf. Mit zunehmendem Abstand wird die Führung eines Halteprofils, beispielsweise bei einer Längsverschiebung zu seiner Positionierung, verbessert, da die Druckpunkte bzw. Druckpunkt und Anschlag weiter auseinander liegen.Preferably, the spring tongue and the tab are arranged on opposite side edges of the second leg. Thus, spring tongue and tab at a distance from each other. With increasing distance becomes the guidance a holding profile, for example, in a longitudinal displacement to its positioning, improved because the pressure points or pressure point and stop are further apart.

Erfindungsgemäß ist die Lasche im Wesentlichen senkrecht zum zweiten Schenkel angeordnet. Bevorzugt ist die Lasche im Wesentlichen senkrecht zum ersten Schenkel .According to the invention, the tab is arranged substantially perpendicular to the second leg. Preferably, the tab is substantially perpendicular to the first leg.

Die Anordnung senkrecht zum zweiten Schenkel weist den Vorteil auf, dass die Führung des Halteprofils über eine schmale Seitenkante der Lasche erfolgt, die gesamte Breite der Lasche jedoch statisch wirksam ist. Dadurch weist die Lasche - im Unterschied zur Federzunge - eine hohe Formsteifigkeit auf, so dass ein Federn der Lasche bei Einführen eines Halteprofils verhindert wird. Dadurch ist eine sichere Führung des Halteprofils gewährleistet.The arrangement perpendicular to the second leg has the advantage that the leadership of the holding profile is made over a narrow side edge of the tab, the entire width of the tab, however, is statically effective. As a result, the tab - in contrast to the spring tongue - a high dimensional stability, so that a spring of the tab is prevented upon insertion of a holding profile. As a result, a secure guidance of the holding profile is ensured.

Vorteilhafterweise umfasst die Lasche zudem wenigstens eine Bohrung zur Aufnahme eines Befestigungsmittels, insbesondere einer Schraube. An der Lasche können somit weitere tragende und/oder aussteifende Konstruktionselemente befestigt werden. Insbesondere bei Anbringung von Deckenbekleidungselementen, die in einem großen Abstand zur tragenden Decke befestigt werden, kann zur Aussteifung der Befestigungsvorrichtung eine Sekundärkonstruktion vorgesehen sein. Bedarf es einer solchen aussteifenden Sekundärkonstruktion, kann diese über die Lasche des Haltewinkels mit der Befestigungsvorrichtung verbunden werden.Advantageously, the tab also comprises at least one bore for receiving a fastening means, in particular a screw. On the tab thus further supporting and / or stiffening construction elements can be attached. In particular, when mounting ceiling cladding elements which are attached at a great distance from the supporting ceiling, a secondary construction may be provided for stiffening the fastening device. If such a stiffening secondary construction is required, it can be connected to the fastening device via the lug of the retaining bracket.

Erfindungsgemäß ist auch die Federzunge zumindest über einen Teilbereich im Wesentlichen senkrecht zum ersten Schenkel angeordnet. Im Unterschied zur Lasche ist dieser Teilbereich jedoch zugleich im Wesentlichen parallel zum zweiten Schenkel geführt. An diesen Teilbereich schließen jeweils in einem stumpfen Winkel weitere Teilbereiche an, die die Federzunge mit dem zweiten Schenkel verbinden oder die Klemmflächen ausbilden, mit denen die Federzunge an einem eingesetzten Halteprofil anliegt. Die einzelnen Teilbereiche der Federzunge werden durch Biegen bzw. Abkanten hergestellt.According to the invention, the spring tongue is arranged at least over a portion substantially perpendicular to the first leg. In contrast to the tab, however, this portion is at the same time guided substantially parallel to the second leg. At this sub-area in each case close at an obtuse angle to further sub-areas which connect the spring tongue with the second leg or form the clamping surfaces with which the spring tongue rests against an inserted retaining profile. The individual sections of the spring tongue are produced by bending or folding.

Weiterhin bevorzugt ist das freie Ende der Federzunge derart abgewinkelt und/oder gebogen, dass eine Einführschräge ausgebildet wird. Die Einführschräge vereinfacht das Einsetzen eines Halteprofils, da sie eine automatische Zentrierung ermöglicht und das Aufbiegen der Federzunge erleichtert.Further preferably, the free end of the spring tongue is angled and / or bent such that an insertion bevel is formed. The insertion bevel simplifies the insertion of a retaining profile, as it allows automatic centering and facilitates the bending of the spring tongue.

Um den Haltewinkel mit einem Untergrund und/oder einem weiteren Halteelement einer Befestigungsvorrichtung zu verbinden, besitzen bevorzugt der erste Schenkel und/oder der zweite Schenkel wenigstens eine Öffnung zur Aufnahme eines Befestigungsmittels. Als Befestigungsmittel zur Verbindung des Haltewinkels mit dem Untergrund werden bevorzugt Schrauben eingesetzt. Die Verbindung weiterer Halteelemente am Haltewinkel kann beispielsweise mittels Schrauben und/oder Nieten erfolgen. Vorteilhafterweise werden die zur Aufnahme der Befestigungsmittel vorgesehenen Öffnungen als Langlöcher ausgeführt. Als Langlöcher ausgeführte Öffnungen ermöglichen zum einen eine Justierung des Halteprofils noch während des Einsetzens der Befestigungsmittel, zum anderen können über die Langlöcher thermisch bedingte Längenänderungen der verbundenen Profile aufgenommen werden. Ein derartiger Haltewinkel ermöglicht somit die Ausbildung eines Gleitpunktes. Zur Ausbildung eines Festpunktes wird ein Haltewinkel verwendet, der anstelle der Langlöcher Rundlöcher besitzt. Ob der Einsatz eines Haltewinkels mit Lang- oder Rundlöchern, das heißt die Ausbildung eines Gleit- oder Festpunktes erforderlich ist, ergibt die jeweilige Objektstatik.To connect the bracket with a substrate and / or another holding element of a fastening device, preferably the first leg and / or the second leg have at least one opening for receiving a fastening means. As fastening means for connecting the bracket with the ground screws are preferably used. The connection of further holding elements on the bracket can be done for example by means of screws and / or rivets. Advantageously, the openings provided for receiving the fastening means are designed as elongated holes. Holes designed as openings permit on the one hand an adjustment of the retaining profile even during the onset of the fastening means, on the other hand thermally induced changes in length of the connected profiles can be taken on the slots. Such a bracket thus allows the formation of a floating point. To form a fixed point, a bracket is used, which has round holes instead of slots. Whether the use of a bracket with long or round holes, that is the formation of a sliding or fixed point is required results in the respective object statics.

Vorzugsweise sind im Bereich des ersten Schenkels mehrere unterschiedliche Löcher angeordnet, die eine Anbringung des Haltewinkels auf verschiedenen Untergründen ermöglichen. So ist für alle Untergründe, egal ob Beton, Holz oder Stahl, nur noch ein Haltewinkel vorzuhalten.Preferably, several different holes are arranged in the region of the first leg, which allow attachment of the bracket on different substrates. Thus, for all substrates, no matter whether concrete, wood or steel, only a holding bracket is available.

Nach einer bevorzugten Ausführungsform besitzt der erste Schenkel zur Aussteifung entlang einer Längskante eine Aufkantung, die vorzugsweise parallel zum zweiten Schenkel verläuft. Die Aufkantung verleiht dem ersten Schenkel und damit dem Haltewinkel insbesondere eine höhere Torsionssteifigkeit. Dadurch ist der Haltewinkel in der Lage auch besonders schwere Lasten zu tragen.According to a preferred embodiment, the first leg for stiffening along a longitudinal edge has an upstand, which is preferably parallel to the second Thigh runs. The upstand gives the first leg and thus the bracket in particular a higher torsional stiffness. As a result, the bracket is able to carry even heavy loads.

Um die Festigkeit des Haltewinkels weiter zu erhöhen, wird des Weiteren die Fertigung des Haltewinkels aus Edelstahl vorgeschlagen. Dieses Material erweist sich als besonders formstabil. Ein Haltewinkel aus Edelstahl ist somit ebenfalls für besonders schwere Lasten geeignet. Edelstahl weist zudem eine geringere Wärmeleitfähigkeit als Aluminium auf, das üblicherweise zur Herstellung derartiger Befestigungsvorrichtungen Verwendung findet. Durch Einsatz eines solchen Haltewinkels kann zudem der Wärmebrücken-Effekt deutlich reduziert werden. Eine thermische Trennung durch zusätzlich angebrachte Isolatoren ist somit nicht erforderlich.In order to increase the strength of the bracket further, the production of the support bracket made of stainless steel is further proposed. This material proves to be particularly dimensionally stable. A bracket made of stainless steel is thus also suitable for particularly heavy loads. Stainless steel also has a lower thermal conductivity than aluminum, which is commonly used for producing such fastening devices. By using such a bracket also the thermal bridge effect can be significantly reduced. A thermal separation by additionally attached insulators is therefore not required.

Da ein aus Edelstahl gefertigter Haltewinkel eine höhere Festigkeit gegenüber einem aus Aluminium gefertigten Haltewinkel aufweist, können hierüber nicht nur besonders schwere Lasten, beispielsweise aus Glas- oder Natursteinfassaden, die ein Gewicht zwischen 80 und 100 kg/m2 haben können, abgetragen werden, sondern auch der Abstand der zu befestigenden plattenförmigen Wand- oder Deckenbekleidungselemente zum Untergrund kann vergrößert werden. Denn ein aus Edelstahl gefertigter Haltewinkel vermag ein größeres Biegemoment aufzunehmen. Somit können auch besonders stark ausgeführte Wärmedämmschichten mittels eines erfindungsgemäßen Haltewinkels problemlos überbrückt werden. Vorteilhafterweise werden Haltewinkel mit unterschiedlichen Auskragungen vorgehalten, so dass unterschiedlichen Dämmschichtstärken Rechnung getragen werden kann.Since a bracket made of stainless steel has a higher strength compared to a bracket made of aluminum, not only particularly heavy loads, such as glass or natural stone facades, which can have a weight between 80 and 100 kg / m 2 , can be removed here, but Also, the distance between the plate-shaped wall or ceiling clothing elements to be fastened to the ground can be increased. Because a made of stainless steel bracket can absorb a larger bending moment. Thus, particularly highly executed thermal barrier coatings can be bridged easily by means of a bracket according to the invention. Advantageously, holding brackets are provided with different projections, so that different insulation thicknesses can be taken into account.

Die ebenfalls zur Lösung der Aufgabe vorgeschlagene Befestigungsvorrichtung für ein Fassadensystem mit wenigstens einem Halteprofil und einem Haltewinkel zur Befestigung wenigstens eines im Wesentlichen plattenförmigen Wand- oder Deckenbekleidungselementes an einem bauseitigen Untergrund zeichnet sich dadurch aus, dass sie einen erfindungsgemäßen Haltewinkel umfasst. Eine derart ausgebildete Befestigungsvorrichtung ermöglicht eine vereinfachte Montage selbst schwerer Glas- oder Natursteinfassaden, indem am Haltewinkel neben einer Federzunge zusätzlich eine von einer Lasche begrenzten Öffnung vorgesehen ist, die einen Anschlag zur genauen Positionierung des Halteprofils in einer Längs- und Querrichtung ausbildet.The likewise proposed for solving the problem fastening device for a facade system with at least one retaining profile and a bracket for attaching at least one substantially plate-shaped wall or ceiling covering element to a site-side underground is characterized characterized in that it comprises a bracket according to the invention. Such a trained fastening device allows for simplified assembly of even heavy glass or natural stone facades by additionally provided on the bracket in addition to a spring tongue an opening delimited by a tab, which forms a stop for accurate positioning of the holding profile in a longitudinal and transverse direction.

Das weiterhin zur Lösung der Aufgabe vorgeschlagene Fassadensystem wiederum zeichnet sich dadurch aus, dass es eine erfindungsgemäße Befestigungsvorrichtung umfasst.The facade system, which is furthermore proposed for solving the problem, in turn, is characterized in that it comprises a fastening device according to the invention.

Das dargestellte Ausführungsbeispiel eines erfindungsgemäßen Haltewinkels besitzt einen ersten Schenkel 1 sowie einen senkrecht hierzu angeordneten zweiten Schenkel 2. Der vorliegende Haltewinkel weist somit im Wesentlichen eine L-Form auf (siehe Fig. 3). Am ersten Schenkel 1 ist an der dem zweiten Schenkel 2 gegenüber liegenden Längskante 12 eine Aufkantung 13 ausgebildet, die der Aussteifung des ersten Schenkels 1 dient. Auf diese Weise wird ein sehr formsteifer erster Schenkel 1 ausgebildet, mittels dessen der Haltewinkel an einem Untergrund befestigbar ist. Da der Untergrund unterschiedlich beschaffen sein kann, weist der erste Schenkel 1 mehrere unterschiedliche, zum Teil als Langlöcher ausgebildete Öffnungen 11 zur Aufnahme von Befestigungsmitteln auf (siehe Fig. 1). Als Befestigungsmittel finden insbesondere Schrauben Einsatz.The illustrated embodiment of a support bracket according to the invention has a first leg 1 and a second leg 2 arranged perpendicular thereto. The present bracket thus substantially has an L-shape (see Fig. 3 ). On the first leg 1, a raised edge 13 is formed on the second leg 2 opposite longitudinal edge 12, which serves to stiffen the first leg 1. In this way, a very dimensionally rigid first leg 1 is formed, by means of which the bracket can be fastened to a substrate. There the base may be of different design, the first leg 1 has a plurality of different, partially formed as slots holes 11 for receiving fasteners (see Fig. 1 ). As fasteners find particular screws use.

Der senkrecht zum ersten Schenkel 1 angeordnete zweite Schenkel 2 weist eine Federzunge 3 sowie eine angeformte Lasche 5 auf, wobei sich Federzunge und Lasche an zwei Seitenkanten 6, 7 des zweiten Schenkels 2 gegenüberliegen. Zur Ausbildung der Federzunge 3 wurde zunächst am zweiten Schenkel 2 ein zungenartiges Stück mittels Stanzen freigelegt. Das zungenartige Stück wurde danach mehrfach abgekantet bzw. gebogen, so dass vier Teilabschnitte hergestellt wurden, von denen ein Teilabschnitt 3.2 parallel und im Abstand zum zweiten Schenkel 2 verläuft. Ein hieran anschließender abgewinkelter Teilabschnitt 3.1 verbindet den parallelen Teilabschnitt 3.2 mit dem zweiten Schenkel 2 des Haltewinkels und ein weiterer am parallelen Teilabschnitt 3.2 anschließender abgewinkelter Teilabschnitt 3.3 führt die Federzunge 3 wieder an den zweiten Schenkel 2 heran. Hieran schließt sich ein vierter Teilabschnitt 3.4 an, der das freie Ende 9 der Federzunge 3 bildet und derart schräg zum zweiten Schenkel 2 geführt ist, dass eine Einführschräge 10 ausgebildet wird, die das Einsetzen eines Halteprofils zwischen der Federzunge 3 und den zweiten Schenkel 2 erleichtern soll (siehe Figuren 2 und 3). Der Abstand der Federzunge 3 zum zweiten Schenkel 2 ist dabei derart gewählt, dass die Federzunge 3 unter Vorspannung an einem eingesetzten Halteprofil anliegt, so dass eine Klemmwirkung erreicht wird.The perpendicular to the first leg 1 arranged second leg 2 has a spring tongue 3 and a molded tab 5, wherein the spring tongue and tab on two side edges 6, 7 of the second leg 2 are opposite. To form the spring tongue 3, a tongue-like piece was first exposed by punching on the second leg 2. The tongue-like piece was then folded or bent several times, so that four sections were made, of which a section 3.2 runs parallel and at a distance from the second leg 2. A subsequent angled section 3.1 connects the parallel section 3.2 with the second leg 2 of the bracket and another on the parallel section 3.2 subsequent angled section 3.3 leads the spring tongue 3 back to the second leg 2 zoom. This is followed by a fourth section 3.4, which forms the free end 9 of the spring tongue 3 and is guided obliquely to the second leg 2, that an insertion bevel 10 is formed, which facilitate the insertion of a retaining profile between the spring tongue 3 and the second leg 2 should (see FIGS. 2 and 3 ). The distance of the spring tongue 3 to the second leg 2 is selected such that the spring tongue 3 is applied under bias to an inserted holding profile, so that a clamping effect is achieved.

An der der Seitenkante 6 gegenüberliegenden Seitenkante 7 des zweiten Schenkels 2 ist die Lasche 5 mittels Stanzen und Biegen angeformt (siehe Figuren 3 und 4). Durch Stanzen wurde die Lasche 5 zunächst freigelegt und danach durch Abkanten im Bereich des verbleibenden Verbindungssteges in eine senkrechte Lage zum zweiten Schenkel 2 gebracht. Die die Lasche 5 freilegende schlitzförmige Ausnehmung bildet zugleich eine Einführöffnung 4 aus, die von einer Seitenkante der Lasche 5 und einer Seitenkante des Steges 4 der Lasche 5 begrenzt wird. Die Einführöffnung 4 dient somit zugleich als in zwei Richtungen wirksamer Anschlag, so dass eine genaue Positionierung eines einzusetzenden Halteprofils erleichtert wird.At the side edge 7 opposite the side edge 7 of the second leg 2, the tab 5 is formed by means of stamping and bending (see Figures 3 and 4 ). By punching the tab 5 was first exposed and then brought by bending in the region of the remaining connecting web in a vertical position to the second leg 2. The tab 5 exposing slot-shaped recess also forms an insertion 4, which from a side edge the tab 5 and a side edge of the web 4 of the tab 5 is limited. The insertion opening 4 thus serves at the same time as an effective stop in two directions, so that an accurate positioning of a holding profile to be used is facilitated.

Der zweite Schenkel 2 weist ebenfalls Öffnungen 11 auf, die vorliegend als Langlöcher ausgebildet sind und der Aufnahme von Befestigungsmitteln zur Befestigung bzw. Lagefixierung eines eingesetzten Halteprofils dienen. Die Ausbildung als Langlöcher gewährleistet dabei die Aufnahme thermisch bedingter Längenänderungen des Halteprofils. Der dargestellte Haltewinkel kann somit zur Ausbildung eines Gleitpunktes eingesetzt werden. Ein entsprechender, jedoch zur Ausbildung eines Festpunktes geeigneter Haltewinkel (nicht dargestellt) weist anstelle der Langlöcher Rundlöcher auf.The second leg 2 also has openings 11, which are in the present case designed as elongated holes and serve to receive fastening means for fixing or fixing the position of an inserted holding profile. The training as slots ensures the recording thermally induced changes in length of the retaining profile. The illustrated bracket can thus be used to form a floating point. A corresponding bracket (not shown) which is suitable for forming a fixed point has round holes instead of the elongated holes.

Die Lasche 5 weist zwei Bohrungen 8 auf, die ebenfalls der Aufnahme von Befestigungsmitteln dienen. So können beispielsweise mittels Schrauben oder Nieten Teile einer aussteifenden Sekundärkonstruktion an der Lasche 5 befestigt werden.The tab 5 has two holes 8, which also serve to receive fasteners. For example, by means of screws or rivets, parts of a stiffening secondary construction can be fastened to the lug 5.

Die Erfindung ist nicht auf die dargestellte Ausführungsform eines Haltewinkels beschränkt. So kann beispielsweise die Länge des zweiten Schenkels 2 variierten, um hierüber den Abstand der zu befestigenden plattenförmigen Wand- oder Deckenbekleidungselemente zum bauseitigen Untergrund festzulegen. Ferner kann die Tiefe der Einführöffnung 4 geändert werden, um hierüber ebenfalls auf den Abstand der plattenförmigen Wand- oder Deckenbekleidungselemente zum Untergrund Einfluss zu nehmen. Des Weiteren können sämtliche Bohrungen 8 bzw. Öffnungen 11 zur Aufnahme von Befestigungsmitteln in unterschiedlicher Form und Größe am ersten Schenkel 1, am zweiten Schenkel 2 und/oder an der Lasche 5 angeordnet sein. Auch die Federzunge 3 kann eine andere Ausgestaltung als dargestellt aufweisen. Beispielsweise kann sie weniger oder mehr als vier Teilabschnitte umfassen. Bei besonders lang gestreckten Befestigungswinkeln kann zudem zwischen der Federzunge 3 und der Lasche 5 wenigstens eine weitere Federzunge 3 angeordnet sein, um die Klemmwirkung zu verstärken.The invention is not limited to the illustrated embodiment of a bracket. For example, the length of the second leg 2 varied in order to determine the distance between the plate-shaped wall or ceiling clothing elements to be fastened to the on-site base. Furthermore, the depth of the insertion opening 4 can be changed in order to influence this also on the distance of the plate-shaped wall or ceiling clothing elements to the ground. Furthermore, all bores 8 or openings 11 for accommodating fastening means of different shape and size can be arranged on the first leg 1, on the second leg 2 and / or on the tab 5. Also, the spring tongue 3 may have a different configuration than shown. For example, it may comprise fewer or more than four subsections. For particularly elongated mounting brackets can In addition, between the spring tongue 3 and the tab 5 at least one further spring tongue 3 may be arranged in order to reinforce the clamping action.
