Description

Die Erfindung betrifft ein Befestigungssystem. Insbesondere betrifft die Erfindung ein Befestigungssystem für ein Fassadenelement. Weiterhin betrifft die Erfindung die Verwendung des Befestigungssystems für die Befestigung eines Fassadenelements in einem Fassadensystem.The invention relates to a fastening system. In particular, the invention relates to a fastening system for a facade element. Furthermore, the invention relates to the use of the fastening system for fastening a facade element in a facade system.

Fassadenelemente werden zum Vorsatz an Gebäuden benutzt. Solche Fassadenelemente können dabei den Werkstoff Aluminium aufweisen, wobei hier und im Folgenden unter dem Begriff Aluminium jeder metallische Werkstoff verstanden wird, der Aluminium enthält. Die Fassadenelemente können aber auch jeden anderen geeigneten Werkstoff, insbesondere jeden anderen metallischen Werkerstoff aufweisen.Façade elements are used for attachment to buildings. Such facade elements can have the material aluminum, the term aluminum being used here and below to mean any metallic material that contains aluminum. However, the façade elements can also have any other suitable material, in particular any other metallic material.

Vorhangfassaden aus Aluminiumprofilen bieten die Möglichkeit, innerhalb kurzer Zeit große Wandflächen an Gebäuden zu bekleiden. Neben der effizienten Montage erlauben Aluminiumelemente einen - im Vergleich zu anderen Baustoffen - relativ großen Gestaltungsspielraum für Architekten und Designer, da sich mit ihnen eine Vielzahl an Oberflächenbeschaffenheiten und Farben umsetzten lassen. Ferner bieten sie - aufgrund ihrer Oberflächeneigenschaften - einen verlässlichen und langlebigen Witterungsschutz der Bausubstanz.Curtain walls made of aluminum profiles offer the possibility of cladding large wall areas on buildings within a short time. In addition to efficient assembly, aluminum elements allow architects and designers - compared to other building materials - a relatively large scope of design, since they can be used to implement a large number of surface textures and colors. Furthermore, due to their surface properties, they offer reliable and long-lasting weather protection for the building fabric.

Aktuell ist die Baubreite von den am häufigsten genutzten Aluminiumsidingprofilen aufgrund der fehlenden Aussteifung orthogonal zur Längsrichtung begrenzt. Beispielsweise werden Aluminiumsidingprofilen auf ca. 400 mm Baubreite begrenzt. Die Fassadenelemente müssen an der Fassade so befestigt sein, dass Umwelteinflüsse, beispielsweise Windlasten, nicht dazu führen, dass Fassadenelement sich von der Fassade lösen. Weitere Anforderungen sind die Möglichkeit einer werkzeuglosen Montage, Einteiligkeit, damit an der Baustelle nicht mit zu vielen Einzelteilen gearbeitet werden muss, und die rüttelsichere Montage der Sidingprofile. Weiterhin müssen die Befestigungselemente auch unter Witterungseinflüssen langlebig sein.The overall width of the most commonly used aluminum siding profiles is currently limited due to the lack of stiffening orthogonal to the longitudinal direction. For example, aluminum siding profiles are limited to a width of approx. 400 mm. The facade elements must be attached to the facade in such a way that environmental influences, such as wind loads, do not cause the facade element to become detached from the facade. Other requirements are the possibility of tool-free assembly, one-piece design so that you don't have to work with too many individual parts on the construction site, and vibration-proof assembly of the siding profiles. Furthermore, the fastening elements must also be durable under the influence of the weather.

Dazu sind Befestigungssysteme bekannt, die eine tragende Unterkonstruktion in Form von Tragprofilen und Befestigungselemente für die Befestigung der Sidingprofile an dem Tragprofil aufweisen. Befestigungselemente sind vielfältig bekannt. Einfache Ausführungen bestehen beispielsweise aus Kunststoff und können einfach in eine Tragschiene eingeklipst werden. Hier kommt es aber zu Problemen mit der Rüttelfestigkeit und Langlebigkeit. Andere Ausführungsformen bestehen aus Metall und werden von vielen Einzelteilen gebildet, was sie teuer in der Herstellung macht. Andere Ausführungsformen weisen an der Baustelle zu montierende Einzelteile auf, was zu einem hohen Montageaufwand vor Ort führt. Infolge steigen die Montagekosten insbesondere bei wachsendem Lohnniveau.For this purpose, fastening systems are known which have a supporting substructure in the form of supporting profiles and fastening elements for fastening the siding profiles to the supporting profile. Fastening elements are widely known. Simple versions are made of plastic, for example, and can simply be clipped into a mounting rail. However, there are problems with the vibration resistance and longevity. Other embodiments are made of metal and are formed from many separate parts, making them expensive to manufacture. Other embodiments have individual parts to be assembled at the construction site, which leads to high assembly costs on site. As a result, assembly costs increase, especially with rising wage levels.

Die üblicherweise als Fassadenelemente eingesetzten Aluminiumfassadenbekleidungssysteme sind Sidingprofile oder Sandwichprofile. Sidingprofile können einschalig oder mehrschalig aufgebaut sein und haben vorgefertigte seitliche Anschlussgeometrien, so dass sie einfach Seite an Seite endlos verbaut werden können. Sidingprofile können auch als Sandwich-Profile mit einer Materialkombination aufgebaut sein, wobei die Aluminiumsichtseite mit einem weiteren Material hinterfüttert ist oder die der Aluminiumsichtseite gegenüberliegende Seite eine Beschichtung aufweist.The aluminum facade cladding systems commonly used as facade elements are siding profiles or sandwich profiles. Siding profiles can be single-layer or multi-layer and have prefabricated lateral connection geometries so that they can simply be installed endlessly side by side. Siding profiles can also be constructed as sandwich profiles with a combination of materials, whereby the visible aluminum side is lined with another material or the side opposite the visible aluminum side has a coating.

Eine weitere Aufgabe der Erfindung besteht in der Angabe eines Verfahrens zur Befestigung eines Fassadenelements. Ein weiterer Aspekt der Erfindung betrifft die Verwendung des Befestigungssystems für die Befestigung eines Fassadenelements.The object of the invention is to provide a fastening system, in particular a fastening system for a facade element, which minimizes the aforementioned disadvantages. A further object of the invention consists in specifying a method for fastening a facade element. Another aspect of the invention relates to the use of the fastening system for fastening a facade element.

Die erste Aufgabe der Erfindung wird mit einem Befestigungssystem gemäß dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Weiterentwicklungen des Befestigungssystems ergeben sich aus den Ansprüchen 2 bis 7. Die weitere Aufgabe der Erfindung wird mit einem Verfahren gemäß Anspruch 8 gelöst. Der weitere Aspekt der Erfindung betrifft die Verwendung eines entsprechenden Befestigungselements gemäß Anspruch 9.The first object of the invention is solved with a fastening system according to independent claim 1 . Advantageous developments of the fastening system result from claims 2 to 7. The further object of the invention is achieved with a method according to claim 8. The further aspect of the invention relates to the use of a corresponding fastening element according to claim 9.

Ein erfinderisches Befestigungssystem weist ein Tragprofil mit Durchbrüchen und eine Befestigungsschale mit Durchbrüchen auf und ist dadurch gekennzeichnet, dass das Befestigungssystem weiterhin eine Befestigungsklammer als Befestigungselement aufweist, wobei die Befestigungsklammer einen Befestigungklammerverbindungssteg aufweist, wobei das Innenmaß der Länge a im Befestigungsklammerverbindungssteg gleich der Differenz des Mittenabstands d der Durchbrüche in dem Tragprofil und der Breite f der Durchbrüche in dem Tragprofil ist und gleich-zeitig größer oder gleich als die Differenz des Mittenab stands g der Durchbrüche in der Befestigungsschale und der Breite h der Durchbrüche in der Befestigungsschale ist. Das Tragprofil kann dabei an einer Gebäudewand befestigt sein. Die Befestigungsschale kann mittels des Befestigungselements an dem Tragprofil befestigt sein. Die Befestigungsschale kann dazu ausgestaltet sein, ein Fassadenelement aufzunehmen. Damit ist mit dem erfinderischen Befestigungssystem ein Fassadenelement an einer Gebäudefassade befestigbar. Insbesondere kann das Fassadenelement mittels des erfinderischen Befestigungssystems ohne Werkzeug verwenden zu müssen an einer Wand, beispielsweise einer Außenwand eines Gebäudes, d.h. einer Gebäudehülle, befestigt werden. Das Tragprofil ist einfach gestaltet und kann beispielsweise ein einfaches, d.h. unprofiliertes, T-Profil sein, bestehend aus einem Steg und einem Flansch als Querteil des T-Profils, wobei der Flansch im Raster angeordnete Aussparungen aufweist.An inventive fastening system has a support profile with openings and a fastening shell with openings and is characterized in that the fastening system also has a fastening clamp as fastening element, the fastening clamp having a fastening clamp connecting web, the internal dimension of the length a in the fastening clamp connecting web being equal to the difference in center distance d of the openings in the support profile and the width f of the openings in the support profile is and at the same time greater than or equal to the difference in center stand g of the openings in the fastening shell and the width h of the openings in the fastening shell. The support profile can be attached to a building wall. The fastening shell can be fastened to the support profile by means of the fastening element. The fastening shell can be designed to accommodate a facade element. A facade element can thus be fastened to a building facade with the fastening system according to the invention. In particular, the facade element can be inventive fastening system without having to use tools on a wall, for example an outer wall of a building, ie a building envelope, are attached. The support profile has a simple design and can be, for example, a simple, ie unprofiled, T-profile consisting of a web and a flange as a transverse part of the T-profile, the flange having recesses arranged in a grid.

In einer vorteilhaften Ausführungsform ist das Befestigungselement als Befestigungsklammer realisiert. Die Befestigungsklammer ist einfach und kostengünstig herstellbar.In an advantageous embodiment, the fastening element is implemented as a fastening clip. The fastening clip is easy and inexpensive to produce.

Die Befestigungsklammer weist zwei Schenkel und ein zwischen den Schenkeln liegenden Befestigungsklammerverbindungssteg auf. Die beiden Schenkel können gleich lang sein. Die beiden Schenkel können auch ungleich lang sein, beispielsweise kann der erste Schenkel zwischen 1mm und 60 mm lang sein, während der zweite Schenkel 1 mm bis 30 mm lang sein kann. In diesem Zahlenbeispiel beträgt die Innenlänge des Befestigungsklammerverbindungsstegs zwischen den Schenkeln zwischen 5 und 80 mm. Es hat sich darüber hinaus aus vorteilhaft erwiesen, wenn der Befestigungsklammerverbindungssteg in Richtung der Schenkel bombiert, also vorgespannt, ist. Durch diese Vorspannung wird die für die Montage wichtige Toleranz in der Verbindung wieder herausgenommen, so dass die Befestigungsschale rüttelfrei auf dem Tragprofil sitzt.The fastening clip has two legs and a fastening clip connecting web lying between the legs. The two legs can be of equal length. The two legs can also be of unequal length, for example the first leg can be between 1 mm and 60 mm long, while the second leg can be 1 mm to 30 mm long. In this numerical example, the inner length of the fastening clip connecting web between the legs is between 5 and 80 mm. In addition, it has proven to be advantageous if the fastening clip connecting web is cambered in the direction of the legs, ie is prestressed. This pre-tension removes the tolerance in the connection that is important for assembly, so that the mounting shell sits on the support profile without shaking.

In einer vorteilhaften Ausführungsform weist das Befestigungssystem genau drei Elemente auf, nämlich das Tragprofil, die Befestigungsschale und die Befestigungsklammer. Damit weist das Befestigungssystem nur drei Einzelteile auf. Da das Tragprofil vor der Montage der Fassadenelemente an die Wand angebracht wird, muss der Monteur des Fassadenelements nur mit dem Fassadenelement selbst sowie der Befestigungsschale und der Befestigungsklammer hantieren, was ihm die Arbeit auf der Baustelle erleichtert.In an advantageous embodiment, the fastening system has exactly three elements, namely the support profile, the fastening shell and the fastening bracket. The fastening system thus has only three individual parts. Since the support profile is attached to the wall before the facade elements are installed the fitter of the facade element only has to handle the facade element itself as well as the fastening shell and the fastening clamp, which makes his work on the construction site easier.

Es hat sich als vorteilhaft erwiesen, wenn das Tragprofil, die Befestigungsschale und die Befestigungsklammer einen metallischen Werkstoff aufweisen. Metallische Werkstoffe weisen eine hohe Resistenz gegen Witterungseinflüsse auf und haben eine vergleichsweise hohe Festigkeit, so dass Rüttelfestigkeit und eine feste Verbindung von Fassadenelementen, auch bei widrigen Umweltbedingungen, beispielsweise hohen Windlasten, gegeben ist.It has proven to be advantageous if the support profile, the mounting shell and the mounting bracket are made of a metallic material. Metallic materials are highly resistant to the effects of weather and have a comparatively high strength, so that there is vibration resistance and a firm connection of facade elements, even under adverse environmental conditions, such as high wind loads.

In einer weiteren vorteilhaften Ausführungsform ist die Befestigungsklammer aus einem Federstahl gefertigt. Federstahl ist ein Stahl, der im Vergleich zu anderen Stählen eine höhere Festigkeit besitzt. Jedes Bauteil kann bis zu einer durch den Werkstoff bestimmten Spannung, der Elastizitätsgrenze, verformt werden, um danach ohne bleibende Verformung elastisch in den Ausgangszustand zurückzukehren. Die Werkstoffeigenschaft, die das ermöglicht, ist die Elastizität. Darüberhinausgehende Verformungen führen zu plastischer Deformation. Beispielsweise hat der Federstahl 38Si7 eine Elastizitätsgrenze von mindestens 1150 N/mm2 bei einer Zugfestigkeit von 1300 bis 1600 N/mm2, verglichen mit 235 N/mm2 bei dem Baustahl S235JR (Zugfestigkeit 360 N/mm2). Der maßgebliche Unterschied ist hierbei das Streckgrenzenverhältnis, d. h. das Verhältnis von Streckgrenze zu Zugfestigkeit des Werkstoffs, welches bei Federstählen üblicherweise im Bereich > 85 % liegt. Der Vorteil der Verwendung von Federstahl für die Befestigungsklammer ist damit, dass sie elastisch verformbar ist und werkzeuglos in Durchbrüche in dem Tragprofil eindrückbar ist. Insbesondere entsteht eine feste formschlüssige Verbindung zwischen der Befestigungsklammer und dem Tragprofil, wenn die Befestigungsklammer bügelförmig mit zwei Schenkeln und einem Verbindungssteg ausgestaltet ist, wobei sich die Schenkelenden im unbelasteten Zustand enger zueinander angeordnet sind als der Verbindungssteg lang ist und das Tragprofil Durchbrüche aufweist, wovon sich jeweils zwei Durchbrüche in einer Entfernung zueinander befinden, die weiter voneinander entfernt sind, als die Schenkelenden der Befindungsklammer im unbelasteten Zustand voneinander entfernt sind, aber nicht weiter voneinander entfernt sind wie die Länge des Verbindungsstegs. Ähnliche Vorzüge lassen sich mit rostfreien Edelstählen, beispielsweise 1. 4310 (X10CrNi18-8), erreichen. Die Materialstärke der Verbindungsklammer kann beispielsweise 0,7 mm betragen.In a further advantageous embodiment, the fastening clip is made from spring steel. Spring steel is a steel that has higher strength than other steels. Every component can be deformed up to a stress determined by the material, the elastic limit, in order to then return elastically to its original state without permanent deformation. The material property that makes this possible is elasticity. Deformations going beyond this lead to plastic deformation. For example, 38Si7 spring steel has an elastic limit of at least 1150 N/mm 2 with a tensile strength of 1300 to 1600 N/mm 2 , compared to 235 N/mm 2 for mild steel S235JR (tensile strength 360 N/mm 2 ). The main difference here is the yield point ratio, ie the ratio of the yield point to the tensile strength of the material, which is usually in the range of > 85% for spring steel. The advantage of using spring steel for the mounting bracket is that it is elastically deformable and can be pressed into openings in the support profile without tools. In particular, a firm form-fitting connection is created between the fastening clamp and the support profile if the fastening clamp is designed in the shape of a bow with two legs and a connecting web, with the ends of the legs being arranged closer to one another in the unloaded state than the length of the connecting web and the support profile having openings, of which two perforations are located at a distance from each other which is further apart than the leg ends of the location clip are apart in the unloaded state, but are not further apart than the length of the connecting bar. Similar benefits can be achieved with stainless steels such as 1. 4310 (X10CrNi18-8). The material thickness of the connecting clip can be 0.7 mm, for example.

In einer weiteren vorteilhaften Ausführungsform weist die Befestigungsschale den Werkstoff Aluminium auf. Aluminium weist bei geringem Gewicht eine ausreichende Festigkeit auf. Ein geringes Gewicht des gesamten Befestigungssystems ist wichtig, um die Statik eines Gebäudes, an dem eine Vorhangfassade aus Fassadenelementen befestigt werden soll, nicht über Gebühr zu beanspruchen.In a further advantageous embodiment, the fastening shell is made of aluminum. Aluminum has sufficient strength with low weight. A low weight of the entire fastening system is important in order not to overburden the statics of a building to which a curtain wall made of facade elements is to be fastened.

In einer weiteren vorteilhaften Ausführungsform weist auch das Tragprofil den Werkstoff Aluminium auf.In a further advantageous embodiment, the support profile is also made of aluminum.

In einer weiteren vorteilhaften Ausführungsform weist das Tragprofil ein Flachprofil mit in einem Raster angeordneten Durchbrüchen auf. Das Flachprofil ist einfach herzustellen und ist nur durch seine Länge, Breite und Materialdicke definiert. Das Flachprofil kann auch durch den Horizontalschenkel eines T-Profils gebildet werden.In a further advantageous embodiment, the support profile has a flat profile with openings arranged in a grid. The flat profile is easy to manufacture and is only defined by its length, width and material thickness. The flat profile can also be formed by the horizontal leg of a T-profile.

In die Durchbrüche des Tragprofils kann die Befestigungsklammer eingeklipst werden. Dazu kann der Mittenabstand der Durchbrüche in dem Tragprofil d beispielsweise 50 mm betragen, wobei die Breite der Durchbrüche in dem Tragprofil f 20 mm betragen kann. Der Mittenabstand der Durchbrüche in der Befestigungsschale g kann beispielsweise 36 mm betragen, wobei die Breite der Durchbrüche in der Befestigungsschale h 20 mm betragen kann. Das Innenmaß der Länge im Befestigungsklammerverbindungssteg a kann in diesem Beispiel 30,2 mm betragen. Es gilt a = d − f ≥ g − h = b .

Figure imgb0001
The mounting bracket can be clipped into the openings in the support profile. For this purpose, the center distance between the openings in the support profile d can be 50 mm, for example, and the width of the openings in the support profile f can be 20 mm. The center distance between the openings in the mounting shell g can be 36 mm, for example, and the width of the openings in the mounting shell h can be 20 mm. The internal dimension of the length in the fastening clip connecting web a can be 30.2 mm in this example. It applies a = i.e − f ≥ G − H = b .
Figure imgb0001

Insbesondere kann die Befestigungsschale und die Befestigungsklammer derart ausgestaltet sein, dass die Befestigungsklammer in die Befestigungsschale einsteckbar ist. Anschließend kann die Befestigungsschale, nun mit der Befestigungsklammer verbunden, einfach in die Durchbrüche an dem Tragprofil befestigt werden. Der Monteur auf der Baustelle hat immer nur mit maximal zwei Bauteilen zu hantieren, indem er zunächst die Befestigungsklammer in die Tagschale steckt, nun die Befestigungsschale mit dem Tragprofil verbindet, indem er die aus der Befestigungsschale ragenden Schenkel der Befestigungsklammer in die entsprechenden Durchbrüche in dem Tragprofil steckt. Nachdem der Monteur eine der Länge des zu montierenden Fassadenelements angepasste Menge an Befestigungsschalen auf diese Weise montiert hat, kann er ein Fassadenelement in die Befestigungsschale betten, so dass das Fassadenelement montiert ist. Dazu wird das Fassadenelement beispielsweise über einen Formschluss mit der Befestigungsschale verbunden.In particular, the mounting shell and the mounting bracket can be designed in such a way that the mounting bracket can be inserted into the mounting shell. The mounting shell, now connected to the mounting bracket, can then be easily attached to the support profile in the openings. The fitter on the construction site only ever has to handle a maximum of two components by first inserting the fastening bracket into the day tray, now connecting the fastening tray to the support profile by removing the one from the Mounting shell protruding leg of the mounting bracket is inserted into the corresponding openings in the support profile. After the fitter one of the Length of the facade element to be mounted has mounted an adjusted amount of fastening shells in this way, he can embed a facade element in the fastening shell, so that the facade element is mounted. For this purpose, the facade element is connected to the fastening shell, for example via a form fit.

Fig. 1 zeigt ein Befestigungssystem 100 gemäß einer ersten Ausführungsform mit einem eingebetteten Fassadenelement 150 in einer Schnittdarstellung. Das Fassadenelement 150 ist in eine Befestigungsschale 120 eingebettet. Die Befestigungsschale 120 ist mit einem Befestigungselement 110 an einem Tragprofil 130 befestigt. Das Befestigungselement 110 weist eine Blattfeder und bewegliche Klipselemente auf. Die Klipselemente sind federbelastet und können hinter einer entsprechenden Einbauöffnung verrasten, d.h. einen Formschluss hinter der Einbauöffnung bilden. Die Blattfeder hält das Befestigungselement 110 in diesem Fall unter Spannung, so dass es rüttelfest in der Einbauöffnung verrastet. Die Klipselemente sind mit beispielsweise mit einem Schraubendreher betätigbar, d.h. insbesondere zurückziehbar, so dass der Hinterschnitt aufgelöst und das Befestigungselement 110 wieder demontierbar ist. Dadurch ist das Befestigungselement 110 wiederverwendbar. Die gezeigte Ausführungsform des Befestigungselements 110 gemäß der ersten Ausführungsform besteht aus Metall. Durch die über mehrere Einzelteile verwirklichten Funktionalitäten machen das Befestigungselement 110 gemäß der ersten Ausführungsform allerdings teuer in der Herstellung. 1 shows a fastening system 100 according to a first embodiment with an embedded facade element 150 in a sectional view. The facade element 150 is embedded in a fastening shell 120 . The fastening shell 120 is fastened to a support profile 130 with a fastening element 110 . The fastening element 110 has a leaf spring and movable clip elements. The clip elements are spring-loaded and can latch behind a corresponding installation opening, ie form a form fit behind the installation opening. In this case, the leaf spring keeps the fastening element 110 under tension, so that it latches in the installation opening without shaking. The clip elements can be actuated, for example with a screwdriver, ie in particular can be pulled back, so that the undercut is released and the fastening element 110 can be removed again. As a result, the fastening element 110 can be reused. The shown embodiment of the fastening element 110 according to the first embodiment consists of metal. However, due to the functionalities realized via several individual parts, the fastening element 110 according to the first embodiment is expensive to manufacture.

Die Befestigungsklammer 110 lässt sich deutlich günstiger herstellen als das Befestigungselement der ersten Ausführungsform. Die Befestigungsklammer 110 ragt mit einem ersten Befestigungsklammerschenkel 115 und einem zweiten Befestigungsklammerschenkel 117 jeweils durch Durchbrüche 124, 134 in dem Verbindungssteg der Befestigungsschale 120 und dem Tragprofil 130. Die beiden Befestigungsschenkelabschnitte 115, 117 sind in dem gezeigten Ausführungsbeispiel unterschiedlich lang, was eine bessere Handhabung bei der Montage ermöglicht. Die Erfindung kann aber auch mit gleich langen Befestigungsabschnitten 115, 117 ausgeführt werden. Die zwei Durchbrüche 124 in dem Befestigungsschalenverbindungssteg 113 weisen einen Abstand b, gemessen zwischen der jeweiligen Innenkante, auf. Die zwei Durchbrüche 134 in dem Tragprofil 130 weisen einen Abstand a, gemessen zwischen der jeweiligen Innenkante, auf. Die beiden Befestigungsklammerschenkel 115, 117 weisen eine Kontur auf, die gegenüber den Durchbrüchen 124, 134 in dem Befestigungsschalenverbindungssteg 123 und dem Tragprofil 130 einen Hinterschnitt bilden. 4 shows a fastening system 100 according to the invention according to a second embodiment. In this embodiment, the fastening element 110 is realized by a fastening clamp 110 . The fastening clip 110 can be manufactured much more cheaply than the fastening element of the first embodiment.

Fig. 6 zeigt eine Befestigungsklammer 110 des erfindungsgemäßen Befestigungssystems 100 in einer weiteren Ausführungsform in einer Seitenansicht. Die Befestigungsklammer 110 weist einen Befestigungsklammerverbindungssteg 113 auf, der an seinen Enden einen ersten Befestigungsklammerschenkel 111 bzw. einen zweiten Befestigungsklammerschenkel 112 aufweist. Die Übergänge zwischen Befestigungsklammerverbindungssteg 113 und dem einen ersten Befestigungsklammerschenkel 111 bzw. dem zweiten Befestigungsklammerschenkel 112 sind mit Radien versehen. Der Befestigungsklammerverbindungssteg 113 dieser weiteren Ausführungsform ist mit einer Vorspannung versehen, d.h. gegenüber dem geraden Verlauf aus der zweiten Ausführungsform mit einer Bombierung mit dem Maß i versehen. Das Maß i kann beispielsweise weniger al 1 mm betragen. Die Bombierung weist in Richtung der Schenkel 111, 112. Durch diese Vorspannung wird die für die Montage wichtige Toleranz in der Verbindung wieder herausgenommen, so dass die mit der Befestigungsklammer 113 dieser Ausführungsform auf dem Tragprofil 130 befestigte Befestigungsschale 120 rüttelfrei auf dem Tragprofil 130 sitzt. 6 shows a fastening clip 110 of the fastening system 100 according to the invention in a further embodiment in a side view.

In der Draufsicht gemäß Fig. 8 (a) ist zu erkennen, dass das Tragprofil 130 ein Flachprofil mit in einem Raster angeordneten Durchbrüchen 134 aufweist. Dabei ist das Flachprofil in der gezeigten Ausführungsform der Horizontalschenkel 135 eines T-Profils. Der Mittenabstand der Durchbrüche 134 in dem Tragprofil 130 beträgt das Maß d, wobei die Breite der Durchbrüche 134 in dem Tragprofil 130 das Maß f beträgt. Dabei verhalten sich die Maße a (Innenmaß Länge Befestigungsklammerverbindungssteg 113), b (Innenabstand zweier benachbarter Durchbrüche 124 in dem Befestigungsschalenverbindungssteg 123), d (Mittenabstand der Durchbrüche 134 im Tragprofil 130), f (Breite eines Durchbruchs 134 im Tragprofil 130). g (Mittenabstand der Durchbrüche 124 in der Befestigungsschale 120) und h (Breite eines Durchbruchs 124 in der Befestigungsschale 120) wie folgt zueinander: a = d-f ≥ g-h = b. Damit ist die Befestigungsklammer 110 mit ihren Schenkeln 111, 112 in die Befestigungsschale 120 und das Tragprofil 130 derart einsteckbar, dass sie die Befestigungsschale 120 mit dem Tragprofil 130 rüttelfest und spiellos verbindet. Ist ein Fassadenelement 150 in die Befestigungsschale 120 eingebettet. so ist auch dieses Fassadenelement über die Befestigungsklammer 110 spiellos und rüttelfest mit dem Tragprofil 130 verbunden. Das Tragprofil 130 ist wie in Fig. 8 (b) zu sehen, beispielsweise als T-Profil mit einem Horizontalschenkel 135 und einem Vertikalschenkel 136 ausgebildet, wobei es mit seinem Vertikalschenkel 136 mit einer Wand 160 verbindbar ist, so dass über das Befestigungssystem 100 ein Fassadenelement rüttel- und spielfrei auf einer Wand 160 montierbar ist. 9 shows a section of a support profile 130 of the fastening system 100 according to the invention of the second embodiment, with FIG Figure 8(a) a top view and in Figure 8(b) the view of an end face is shown. According to the top view Figure 8(a) it can be seen that the support profile 130 has a flat profile with openings 134 arranged in a grid. The flat profile in the embodiment shown is the horizontal leg 135 of a T-profile. The center distance between the openings 134 in the support profile 130 is dimension d, the width of the openings 134 in the supporting profile 130 being dimension f. The dimensions a (internal length of the fastening clip connecting web 113), b (internal distance between two adjacent openings 124 in the fastening shell connecting web 123), d (center distance of the openings 134 in the support profile 130), f (width of an opening 134 in the support profile 130) are related. g (center distance of the openings 124 in the fastening shell 120) and h (width of an opening 124 in the fastening shell 120) to one another as follows: a=df≧gh=b. The mounting bracket 110 can thus be inserted with its legs 111, 112 into the mounting shell 120 and the support profile 130 in such a way that it connects the mounting shell 120 to the support profile 130 in a vibration-resistant and play-free manner. Is a facade element 150 embedded in the mounting shell 120. this facade element is also connected to the support profile 130 via the fastening clamp 110 without play and without shaking. The support profile 130 is as in Figure 8(b) embodied, for example, as a T-profile with a horizontal leg 135 and a vertical leg 136, it being connectable with its vertical leg 136 to a wall 160, so that a façade element can be mounted on a wall 160 without vibration and play via the fastening system 100.
