Description

Die Erfindung betrifft eine Fassade mit einem zwischen einer Wand und zumindest einer Fassadenplatte angeordneten wärmedämmenden Material, wobei eine die Wand mit der Fassadenplatte verbindende Metallkonstruktion vorgesehen ist, welche eine erste Lage von Metallprofilen und eine zweite Lage von Metallprofilen aufweist, wobei die zweite Lage von Metallprofilen die Fassadenplatte trägt.The invention relates to a facade with a heat-insulating material arranged between a wall and at least one facade panel, with a metal construction connecting the wall to the facade panel being provided, which has a first layer of metal profiles and a second layer of metal profiles, the second layer of metal profiles supports the facade panel.

Weiter betrifft die Erfindung ein Verfahren zur Herstellung einer wärmedämmenden Fassade, wobei eine erste Lage von Metallprofilen mit einer Wand verbunden wird, wonach eine zweite Lage von Metallprofilen mit der ersten Lage von Metallprofilen verbunden wird, wonach zumindest eine Fassadenplatte mit der zweiten Lage von Metallprofilen verbunden wird.The invention also relates to a method for producing a heat-insulating facade, in which a first layer of metal profiles is connected to a wall, after which a second layer of metal profiles is connected to the first layer of metal profiles, after which at least one facade panel is connected to the second layer of metal profiles will.

Fassaden der eingangs genannten Art und Verfahren zur Herstellung solcher Fassaden sind aus dem Stand der Technik hinlänglich bekannt, um brandsichere Fassaden auszubilden, bei welchen insbesondere keine Holzlatten erforderlich sind. Als nachteilig hat sich bei derartigen Fassaden herausgestellt, dass bei intensiver Sonneneinstrahlung unterschiedliche thermische Dehnungen der Metallkonstruktion einerseits und der Fassadenplatten andererseits zu thermischen Spannungen führen, welche zu Beschädigungen der Fassade führen können.Facades of the type mentioned at the outset and methods for producing such facades are well known from the prior art in order to form fireproof facades in which, in particular, no wooden slats are required. A disadvantage of such facades has been found that in intense sunlight, different thermal expansions of the metal structure on the one hand and the facade panels on the other hand lead to thermal stresses, which can lead to damage to the facade.

Hier setzt die Erfindung an. Aufgabe der Erfindung ist es, eine Fassade der eingangs genannten Art anzugeben, welche einerseits einfach herstellbar und andererseits unempfindlich gegenüber Änderungen der Außentemperatur ist.This is where the invention comes in. The object of the invention is to provide a facade of the type mentioned, which on the one hand is easy to produce and on the other hand is insensitive to changes in the outside temperature.

Weiter soll ein Verfahren zur Herstellung einer solchen Fassade angegeben werden.A method for producing such a facade is also to be specified.

Die erste Aufgabe wird erfindungsgemäß durch eine Fassade der eingangs genannten Art gelöst, bei welcher die zweite Lage von Metallprofilen über zumindest zwei Schrauben, welche jeweils einen Kopfabschnitt und einen Schaftabschnitt aufweisen, mit der Fassadenplatte verbunden ist, wobei die Schrauben durch Durchgangslöcher in der Fassadenplatte ragen und in ein Metallprofil der zweiten Lage geschraubt sind, wobei die Durchgangslöcher einen Durchmesser aufweisen, welcher größer als ein Durchmesser der Schrauben im Schaftabschnitt ist.The first object is achieved according to the invention by a facade of the type mentioned at the outset, in which the second layer of metal profiles is connected to the facade panel via at least two screws, each of which has a head section and a shaft section, with the screws protruding through through-holes in the facade panel and are screwed into a metal profile of the second layer, the Through holes have a diameter which is larger than a diameter of the screws in the shank portion.

Im Rahmen der Erfindung wurde erkannt, dass durch eine entsprechende Übermaßpassung an der Schraube Spannungen aufgrund unterschiedlicher Wärmeausdehnungskoeffizienten der Fassadenplatte und der Metallkonstruktion auf einfache Weise vermieden werden können.Within the scope of the invention, it was recognized that stresses due to different coefficients of thermal expansion of the facade panel and the metal structure can be avoided in a simple manner by means of a corresponding interference fit on the screw.

Bevorzugt ist vorgesehen, dass die Fassadenplatte relativ zur Metallkonstruktion in einer Ebene bewegbar ist. Die Ebene ist dabei üblicherweise senkrecht zu einer Achse der Schrauben bzw. einer Hauptebene der Fassadenplatte, sodass unterschiedliche Dehnungen der Metallkonstruktion und der Fassadenplatte in einer entsprechenden Ebene einfach durch Relativbewegungen ausgeglichen werden können, welche sich üblicherweise durch einen Durchmesser der Durchgangslöcher ergeben, welcher größer ist als ein Durchmesser der Schrauben im Schaftabschnitt bzw. als ein Durchmesser der Schrauben in jenem Schaftabschnitt, in welchem die Schrauben innerhalb der Fassadenplatte angeordnet sind.Provision is preferably made for the facade panel to be movable in one plane relative to the metal structure. The plane is usually perpendicular to an axis of the screws or a main plane of the facade panel, so that different expansions of the metal structure and the facade panel in a corresponding plane can be easily compensated for by relative movements, which usually result from a larger diameter of the through holes as a diameter of the screws in the shank section or as a diameter of the screws in that shank section in which the screws are arranged within the facade panel.

Es hat sich bewährt, dass die Schrauben einen Hinterschnitt aufweisen, wobei ein Durchmesser bei Schrauben im Bereich des Hinterschnittes um zumindest 1 mm kleiner ist als ein Durchmesser der Durchgangslöcher in der Fassadenplatte. Die Schrauben weisen somit kein Gewinde auf, welches sich bis zum Schraubenkopf erstreckt, sondern sind in einem Bereich des Hinterschnittes zwischen dem Schraubenkopf und dem Gewinde gewindelos ausgebildet. Dadurch sind Beschädigungen der Fassadenplatte auch dann auf einfache Weise vermieden, wenn diese durch Wärmedehnungen an den Schrauben anliegen. Der Bereich des Hinterschnittes der Schrauben ist üblicherweise jener Bereich, welcher bei fertig montierter Fassade innerhalb der Fassadenplatte bzw. im Durchgangsloch positioniert ist.It has proven useful for the screws to have an undercut, with the diameter of the screws in the area of the undercut being at least 1 mm smaller than the diameter of the through-holes in the facade panel. The screws therefore do not have a thread that extends to the screw head, but are designed without a thread in an area of the undercut between the screw head and the thread. As a result, damage to the facade panel is also avoided in a simple manner if it is in contact with the screws due to thermal expansion. The area of the undercut of the screws is usually that area which is positioned within the facade panel or in the through hole when the facade is fully assembled.

Eine hohe Stabilität der Fassade wird erreicht, wenn die Fassadenplatte über drei Schrauben mit dem Metallprofil der zweiten Lage verbunden ist. Es versteht sich, dass die Fassade üblicherweise eine Vielzahl entsprechender Fassadenplatten aufweist. Bevorzugt sind sämtliche Fassadenplatten der Fassade entsprechend ausgebildet und über entsprechende Schrauben mit der Metallkonstruktion verbunden.A high stability of the facade is achieved if the facade panel is connected to the metal profile of the second layer with three screws. It goes without saying that the facade usually has a large number of corresponding facade panels. All facade panels are preferably designed to correspond to the facade and are connected to the metal structure by appropriate screws.

Es hat sich bewährt, dass die Durchgangslöcher zumindest 30 mm von einer Unterkante der Fassadenplatte und zumindest 20 mm, vorzugsweise zumindest 25 mm, von einer Seitenkante der Fassadeplatte beabstandet sind. Dadurch wird eine Rissbildung im Bereich der Durchgangslöcher auf einfache Weise vermieden.It has proven useful that the through holes are spaced at least 30 mm from a lower edge of the facade panel and at least 20 mm, preferably at least 25 mm, from a side edge of the facade panel. This avoids the formation of cracks in the area of the through-holes in a simple manner.

Bevorzugt ist vorgesehen, dass die Fassadenplatte eine Breite von 400 mm bis 800 mm, vorzugsweise etwa 600 mm, aufweist.It is preferably provided that the facade panel has a width of 400 mm to 800 mm, preferably about 600 mm.

Weiter ist bei einer erfindungsgemäßen Fassade bevorzugt vorgesehen, dass die Fassadenplatte eine Höhe von 200 mm bis 400 mm, vorzugsweise etwa 300 mm aufweist.Furthermore, with a facade according to the invention, it is preferably provided that the facade panel has a height of 200 mm to 400 mm, preferably about 300 mm.

Natürlich kann eine erfindungsgemäß ausgebildete Fassade auch mit Fassadenplatten anderer Abmessungen, insbesondere mit kleinformatigen Fassadenplatten, ausgebildet sein.Of course, a facade designed according to the invention can also be designed with facade panels of other dimensions, in particular with small-format facade panels.

Günstig ist es, wenn zumindest einige Fassadenplatten der Fassade zumindest teilweise übereinander positioniert sind, wobei bevorzugt eine obere Fassadenplatte eine untere Fassadenplatte an einem unteren Ende teilweise überlappt. Dadurch ist ein Eindringen von Wasser in die Fassade auf einfache Weise vermieden. Üblicherweise sind die Fassadenplatten nur in einem Bereich eines unteren Endes mit Durchgangslöchern versehen, durch welche diese mit der Metallkonstruktion verbunden werden. Bevorzugt ist dann vorgesehen, dass die Durchgangslöcher der oberen Fassadenplatte unmittelbar oberhalb einer Oberkante der unteren Fassadenplatte angeordnet sind.It is favorable if at least some facade panels of the facade are at least partially positioned one above the other, with an upper facade panel preferably partially overlapping a lower facade panel at a lower end. This prevents water from penetrating the facade in a simple manner. Usually, the facade panels are only provided with through holes in a region of a lower end, through which they are connected to the metal structure. Provision is then preferably made for the through-holes of the upper facade panel to be arranged directly above an upper edge of the lower facade panel.

Bei einer solchen Konstruktion ist bevorzugt vorgesehen, dass zumindest eine Schraube, bevorzugt sämtliche Schrauben, welche eine Fassadenplatte durchdringt, die eine andere Fassadenplatte an einem unteren Ende teilweise überlappt, einen Hinterschnitt mit einer Länge aufweist, welche etwa einer Dicke von zwei Fassadenplatten entspricht. Dadurch können Beschädigungen der Fassadenplatten, welche durch ein Anliegen eines Gewindes an einer Innenseite der Durchgangslöcher entstehen könnten, auf einfache Weise vermieden werden, auch wenn eine Fassadenplatte mit den Schrauben mit der Metallkonstruktion verbunden wird, welche eine darunter angeordnete Fassadenplatte überlappt.In such a construction it is preferably provided that at least one screw, preferably all screws, which penetrates a facade panel which partially overlaps another facade panel at a lower end, has an undercut with a length which corresponds approximately to a thickness of two facade panels. As a result, damage to the facade panels, which could result from a thread touching an inside of the through-holes, can be avoided in a simple manner, even if a facade panel is connected with the screws to the metal structure which overlaps a facade panel arranged underneath.

Die Schrauben sind bevorzugt als Edelstahl ausgebildet, um eine einfache Montage zu gewährleisten.The screws are preferably designed as stainless steel to ensure easy assembly.

Es hat sich bewährt, dass die Metallprofile aus Aluminium ausgebildet sind, um eine leichtgewichtige und korrosionsbeständige Konstruktion zu erreichen.It has been proven that the metal profiles are made of aluminum in order to achieve a lightweight and corrosion-resistant construction.

Ein besonders einfacher Arbeitsablauf ist gewährleistet, wenn die Schrauben jeweils eine Bohrspitze aufweisen. Dadurch können die Fassadenplatten ohne ein vorgehendes Bohren von Löchern in den Metallprofilen bzw. ohne Schneiden von Gewinden in den Metallprofilen in die Metallprofile eingeschraubt werden, indem die Bohrungen in die Metallprofile während des Einschraubens der Schrauben gebildet werden.A particularly simple workflow is guaranteed if the screws each have a drill bit. As a result, the facade panels can be screwed into the metal profiles without previously drilling holes in the metal profiles or without cutting threads in the metal profiles, in that the holes are formed in the metal profiles during screwing in of the screws.

Die Fassadenplatten können grundsätzlich auf jede beliebige Weise ausgebildet sein, beispielsweise als Metallplatten, als Kunststoffplatten, als Holzplatten oder dergleichen. Ein besonders kostengünstiger und witterungsbeständiger Aufbau wird erreicht, wenn die Fassadenplatte als Faserzementplatte ausgebildet ist.In principle, the facade panels can be designed in any desired manner, for example as metal panels, as plastic panels, as wooden panels or the like. A particularly inexpensive and weather-resistant construction is achieved when the facade panel is designed as a fiber cement panel.

Üblicherweise ist vorgesehen, dass die Metallprofile der ersten Lage etwa normal zu den Metallprofilen der zweiten Lage ausgerichtet sind. Die Metallprofile der ersten Lage sind in der Regel horizontal ausgerichtet und die Metallprofile der zweiten Lage sind in der Regel vertikal ausgerichtet. Durch die Anordnung von zwei Lagen von Metallprofilen kann ein besonders einfacher Aufbau erreicht werden, weil an wenigen Metallprofilen der ersten Lage, welche vergleichsweise aufwendig zu befestigen sind, zumal diese mit einer Wand eines Gebäudes zu verbinden sind, eine Vielzahl von Metallprofilen der zweiten Lage verbunden werden kann, welche aufgrund einer Metall-Metall-Verbindung zwischen den Profilen der ersten Lage und den Profilen der zweiten Lage sehr einfach mit den Metallprofilen der ersten Lage verbunden werden können. Dadurch können die Metallprofile der zweiten Lage mit geringem Arbeitsaufwand einen derart geringen Abstand zueinander aufweisen, dass auch kleinformatige Fassadenplatten an den Metallprofilen einfach befestigbar sind.It is usually provided that the metal profiles of the first layer are aligned approximately normal to the metal profiles of the second layer. The metal profiles of the first layer are usually oriented horizontally and the metal profiles of the second layer are usually oriented vertically. By arranging two layers of metal profiles, a particularly simple structure can be achieved because a large number of metal profiles of the second layer are connected to a few metal profiles of the first layer, which are comparatively difficult to attach, especially since they are to be connected to a wall of a building can be, which can be very easily connected to the metal profiles of the first layer due to a metal-to-metal connection between the profiles of the first layer and the profiles of the second layer. As a result, the metal profiles of the second layer can have such a small distance from one another with little effort that even small-format facade panels can be easily attached to the metal profiles.

Die weitere Aufgabe wird erfindungsgemäß durch ein Verfahren der eingangs genannten Art gelöst, bei welchem die Fassadenplatte über durch Durchgangslöcher ragende Schrauben, welche einen Kopfabschnitt und einen Schaftabschnitt aufweisen, mit der zweiten Lage von Metallprofilen verbunden wird, wobei ein Durchmesser der Schrauben im Schaftabschnitt geringer ist als ein Durchmesser der Durchgangslöcher.The further object is achieved by a method of the type mentioned, in which the facade panel projecting through through holes screws having a head portion and a shank portion, with the second layer of metal profiles is connected, wherein a diameter of the screws in the shank portion is smaller than a diameter of the through holes.

Dadurch wird eine Fassade erreicht, welche einerseits aufgrund des Einsatzes von Metallprofilen brandsicher ist und andererseits auch über einen großen Temperaturbereich hinweg einsetzbar ist, zumal unterschiedliche Wärmedehnungen der Fassadenplatten und der Metallprofile durch eine Spielpassung im Bereich der Schrauben und der Durchgangslöcher in den Fassadenplatten leicht ausgeglichen werden können.In this way, a facade is achieved which, on the one hand, is fireproof due to the use of metal profiles and, on the other hand, can also be used over a wide temperature range, especially since different thermal expansions of the facade panels and the metal profiles are easily compensated for by a loose fit in the area of the screws and the through-holes in the facade panels be able.

Further features, advantages and effects of the invention result from the exemplary embodiment presented below. The drawings to which reference is made show:
  • 1 and 2 various work steps of a method for producing a facade according to the invention;
  • Figures 3 and 4 Screws for connecting facade panels with metal profiles of the second layer;
  • figure 5 a front view of a facade panel;
  • 6 a sectional view of a facade according to the invention.

Fig. 1 und 2 zeigen verschiedene Verfahrenszustände eines Verfahrens zur Herstellung einer erfindungsgemäßen Fassade. Wie ersichtlich sind an einer Wand 1 zwei Lagen von Metallprofilen angeordnet, wobei die Metallprofile der ersten Lage, welche als L-Profile 14 ausgebildet sind, über Wandwinkelstützen an der Wand 1 befestigt und horizontal ausgerichtet sind. An diesen L-förmigen Metallelementen der ersten Lage sind wie in Fig. 2 ersichtlich vertikal ausgerichtete Metallprofile einer zweiten Lage angeordnet, welche in einem Querschnitt etwa Hut-förmig bzw. als sogenannte Hut-Profile 16 ausgebildet sind. Die Metallprofile der zweiten Lage sind mit den Metallprofilen der ersten Lage, welche üblicherweise sämtlich aus Aluminium bestehen, durch eine Metall-Metall-Verbindung, beispielsweise eine Schraubverbindung, verbunden. 1 and 2 show different process states of a method for producing a facade according to the invention. As can be seen, two layers of metal profiles are arranged on a wall 1, the metal profiles of the first layer, which are designed as L-profiles 14, being fastened to the wall 1 via wall brackets and aligned horizontally. On these L-shaped metal elements of the first layer, as in 2 vertically aligned metal profiles of a second layer can be seen, which are approximately hat-shaped in cross-section or designed as so-called hat profiles 16 . The metal profiles of the second layer are connected to the metal profiles of the first layer, which are usually all made of aluminum, by a metal-to-metal connection, for example a screw connection.

Fig. 1 zeigt dabei einen Arbeitsschritt, in welchem die L-Profile 14 der ersten Lage bereits über die Wandwinkelstützen an der Wand 1 befestigt sind, wonach zwischen den Profilen der ersten Lage wärmedämmendes Material in Form von Matten 13 aus Steinwolle angeordnet ist. 1 shows a step in which the L-profiles 14 of the first layer are already attached to the wall brackets on the wall 1, after which between the profiles the first layer of insulating material is arranged in the form of mats 13 made of rock wool.

Fig. 2 zeigt einen späteren Arbeitsschritt, in welchem an den Metallprofilen der ersten Lage bereits die senkrechten Metallprofile der zweiten Lage über den Matten 13 befestigt sind. In einem dritten, nicht dargestellten Arbeitsschritt werden dann an den Metallprofilen der zweiten Lage Fassadenplatten 2 befestigt, und zwar üblicherweise mit drei Schrauben 3, weswegen ein horizontaler Abstand zwischen den Metallprofilen der zweiten Lage in der Regel weniger als 50 Prozent einer Breite 11 der Fassadenplatten 2 entspricht. 2 shows a later step in which the vertical metal profiles of the second layer are already attached to the metal profiles of the first layer over the mats 13. In a third work step, not shown, facade panels 2 are then attached to the metal profiles of the second layer, usually with three screws 3, which is why a horizontal distance between the metal profiles of the second layer is usually less than 50 percent of a width 11 of the facade panels 2 is equivalent to.

Fig. 3 und 4 zeigen Schrauben 3, mit welchen die Fassadenplatten 2 an den Metallprofilen der zweiten Lage befestigt sind bzw. befestigt werden. Wie ersichtlich weisen die Schrauben 3 jeweils einen Kopfabschnitt 4 und einen Schaftabschnitt 5 auf, wobei der Schaftabschnitt 5 einen Hinterschnitt 6, ein Gewinde und eine Bohrspitze 7 aufweist. Die üblicherweise aus Edelstahl gebildeten Schrauben 3 sind somit dazu geeignet, auf einfache Weise in die Metallprofile der zweiten Lage geschraubt zu werden, und zwar ohne dass zuvor in einem gesonderten Arbeitsschritt mit einem separaten Bohrer Bohrungen in die Metallprofile eingebracht werden. Dadurch können die Fassadenplatten 2 auf besonders einfache Weise an den Metallprofilen befestigt werden. Figures 3 and 4 show screws 3, with which the facade panels 2 are fastened or are fastened to the metal profiles of the second layer. As can be seen, the screws 3 each have a head section 4 and a shank section 5 , the shank section 5 having an undercut 6 , a thread and a drill bit 7 . The screws 3, which are usually made of stainless steel, are therefore suitable for being screwed into the metal profiles of the second layer in a simple manner, without having to drill holes in the metal profiles in a separate work step using a separate drill. As a result, the facade panels 2 can be attached to the metal profiles in a particularly simple manner.

Um thermische Dehnungen der Metallprofile relativ zu den Fassadenplatten 2 zu ermöglichen, sodass Beschädigungen durch thermisch verursachte mechanische Spannungen vermieden werden, weisen die Durchgangslöcher 8 in den Fassadenplatten 2 einen größeren Durchmesser als die Schrauben 3 im Bereich des Hinterschnittes 6 auf. Im dargestellten Ausführungsbeispiel beträgt der Durchmesser der Schrauben 3 im Bereich des Hinterschnittes 6 etwa 2,8 mm und der Durchmesser der Durchgangslöcher 8 in den Fassadenplatten 2 etwa 4,8 mm, sodass bei zentrischer Positionierung der Schrauben 3 in den Durchgangslöchern 8 eine Bewegbarkeit in jede Richtung in einer Ebene normal zu einer Längsachse 17 der Schrauben 3 von etwa 1 mm gegeben ist.In order to allow thermal expansion of the metal profiles relative to the facade panels 2 so that damage from thermally induced mechanical stresses is avoided, the through holes 8 in the facade panels 2 have a larger diameter than the screws 3 in the area of the undercut 6 . In the illustrated embodiment, the diameter of the screws 3 in the area of the undercut 6 is about 2.8 mm and the diameter of the through holes 8 in the facade panels 2 is about 4.8 mm, so that when the screws 3 are positioned centrally in the through holes 8, mobility in each Direction is given in a plane normal to a longitudinal axis 17 of the screws 3 of about 1 mm.

Fig. 3 zeigt dabei eine Schraube 3, mit welcher eine einzelne Fassadenplatte 2 an den Metallprofilen der zweiten Lage befestigt werden kann. Der Hinterschnitt 6 weist dabei eine etwa der Dicke einer Platte entsprechende Länge auf. Fig. 4 zeigt eine entsprechende Schraube 3, mit welcher zwei einander überlappende Fassadenplatten 2 an einem Metallprofil der zweiten Lage befestigt werden können. Eine Länge des Hinterschnittes 6 entspricht dabei etwa der Dicke zweier aufeinander liegender Fassadenplatten 2, sodass mit dieser Schraube 3 beispielsweise übereinander angeordnete Fassadenplatten 2 in einer einander teilweise überlappenden Weise mit einer Schraube 3 gemeinsam an einem Hut-Profil 16 befestigt werden können. Nachdem Fassadenplatten 2 in der Regel überlappend angeordnet sind, werden die in Fig. 4 dargestellten langen Schrauben 3 häufiger als die in Fig. 3 dargestellten kurzen Schrauben 3 eingesetzt, welche kurzen Schrauben 3 üblicherweise nur an einem unteren Ende einer Fassade oder ähnlichen Positionen eingesetzt werden, an denen Fassadenplatten 2 einander nicht überlappen. 3 shows a screw 3, with which a single facade panel 2 can be attached to the metal profiles of the second layer. The undercut 6 has it a length corresponding approximately to the thickness of a plate. 4 shows a corresponding screw 3, with which two overlapping facade panels 2 can be attached to a metal profile of the second layer. A length of the undercut 6 corresponds approximately to the thickness of two facade panels 2 lying one on top of the other, so that with this screw 3, for example, facade panels 2 arranged one above the other can be fastened together with a screw 3 to a hat profile 16 in a partially overlapping manner. After facade panels 2 are usually arranged in an overlapping manner, the 4 shown long screws 3 more often than in 3 shown short screws 3 used, which short screws 3 are usually used only at a lower end of a facade or similar positions where facade panels 2 do not overlap each other.

Fig. 5 zeigt eine schematische Darstellung einer Fassadenplatte 2 für eine erfindungsgemäße Fassade. Wie ersichtlich weist die Fassadenplatte 2 drei Durchgangslöcher 8 auf, über welche die Fassadenplatte 2 an den Metallprofilen der zweiten Lage befestigbar ist. Üblicherweise weist eine entsprechende Fassadenplatte 2 nur in einem unteren Bereich wie dargestellt drei Durchgangslöcher 8 auf. figure 5 shows a schematic representation of a facade panel 2 for a facade according to the invention. As can be seen, the facade panel 2 has three through holes 8, via which the facade panel 2 can be fastened to the metal profiles of the second layer. A corresponding facade panel 2 usually has three through-holes 8 only in a lower region, as shown.

Die dargestellte Fassadenplatte 2 weist eine Breite 11 von etwa 600 mm und eine Höhe 12 von etwa 300 mm auf. Die seitlichen Durchgangslöcher 8 weisen jeweils einen Abstand zur nächstliegenden Seitenkante 10 von etwa 25 mm und einen Abstand zur Unterkante 19 der Fassadenplatte 2 von etwa 37 mm auf, sodass zuverlässig verhindert ist, dass die Fassadenplatte 2 an den Durchgangslöchern 8 einreißt.The facade panel 2 shown has a width 11 of about 600 mm and a height 12 of about 300 mm. The lateral through-holes 8 each have a distance from the nearest side edge 10 of approximately 25 mm and a distance from the lower edge 19 of the facade panel 2 of approximately 37 mm, so that the facade panel 2 is reliably prevented from tearing at the through-holes 8 .

Fig. 6 zeigt einen Schnitt durch eine erfindungsgemäße Fassade. Ersichtlich ist, dass an der Wand 1 ein horizontal ausgerichtetes L-Profil 14 über Wandwinkelstützen 18 befestigt ist, wobei am L-Profil 14 ein vertikal ausgerichtetes Hut-Profil 16 angeordnet ist, an welchem Hut-Profil 16 die Fassadenplatten 2 mittels in Durchgangslöchern 8 positionierten Schrauben 3 befestigt sind. Wie ersichtlich überlappt dabei eine obere Fassadenplatte 2 eine untere Fassadenplatte 2 an einem unteren Ende, sodass ein Eindringen von Nässe in die Fassade bzw. zu den Matten 13 des Dämmmaterials auf einfache Weise vermieden ist. Die in Fig. 6 ersichtliche Schraube 3 entspricht dabei der in Fig. 4 dargestellten Schraube 3 und weist einen Hinterschnitt 6 mit einer Länge auf, welche etwa einer Dicke zweier aufeinander liegender Fassadenplatten 2 entspricht. Dadurch sind sowohl Beschädigungen der oberen Fassadenplatte 2, welche die Schraube 3 durchdringt, als auch Beschädigungen der unteren Fassadenplatte 2 durch das Gewinde auf einfache Weise vermieden. Wie ersichtlich sind die Fassadenplatten 2 derart angeordnet, dass die Oberkante 9 der unteren Fassadenplatte 2 knapp unter den Durchgangslöchern 8 der oberen Fassadenplatte 2 bzw. knapp unter den Schrauben 3 angeordnet ist, sodass sich eine Überlappung von etwa 30 mm ergibt. Dies gewährleistet eine gute Fixierung der beiden Fassadenplatten 2 mit den Schrauben 3, wobei ein Eindringen von Nässe zuverlässig vermieden ist. 6 shows a section through a facade according to the invention. It can be seen that a horizontally oriented L-profile 14 is attached to the wall 1 via wall brackets 18, with a vertically oriented hat profile 16 being arranged on the L-profile 14, on which hat profile 16 the façade panels 2 are attached by means of through holes 8 positioned screws 3 are fixed. As can be seen, an upper facade panel 2 overlaps a lower facade panel 2 at a lower end, so that penetration of moisture into the facade or to the mats 13 of the insulating material is avoided in a simple manner. In the 6 The visible screw 3 corresponds to the in 4 screw 3 shown and has an undercut 6 with a length which corresponds approximately to a thickness of two superimposed facade panels 2. As a result, both damage to the upper facade panel 2, which the screw 3 penetrates, and damage to the lower facade panel 2 by the thread are avoided in a simple manner. As can be seen, the facade panels 2 are arranged such that the upper edge 9 of the lower facade panel 2 is located just below the through holes 8 of the upper facade panel 2 or just below the screws 3, resulting in an overlap of about 30 mm. This ensures a good fixation of the two facade panels 2 with the screws 3, with penetration of moisture is reliably avoided.

Eine erfindungsgemäße Fassade ist einerseits einfach herstellbar, zumal nur vergleichsweise wenige Verbindungen zwischen den Metallprofilen der ersten Lage und der Wand 1 des Gebäudes, an welcher die Fassade angeordnet ist, über Wandwinkelstützen oder dergleichen hergestellt werden müssen und dennoch aufgrund der Möglichkeit, Profile der zweiten Lage auf einfache Weise mit den Metallprofilen der ersten Lage zu verbinden, eine Vielzahl vertikal ausgerichteter Metallprofile der zweiten Lage zur Aufnahme auch kleinformatiger Fassadenplatten 2 angeordnet werden können. Darüber hinaus ist eine erfindungsgemäße Fassade auch feuerbeständig bzw. erfüllt aktuelle entsprechende Richtlinien, zumal keine Holzlatten mehr erforderlich sind, um die Matten 13 des Dämmmaterials und die Fassadenplatten 2 mit der Wand 1 zu verbinden. Darüber hinaus ist aufgrund der Spielpassung, mit welcher die Schrauben 3 in den Durchgangslöchern 8 der Fassadenplatten 2 angeordnet sind, auch eine Bewegbarkeit in einer Ebene senkrecht zu einer Achse der Schrauben 3 bzw. einer Ebene der Fassadenplatten 2 gegeben, sodass unterschiedliche thermische Dehnungen der Metallprofile und der Fassadenplatte 2 leicht ausgeglichen werden können.On the one hand, a facade according to the invention is easy to produce, especially since only comparatively few connections have to be made between the metal profiles of the first layer and the wall 1 of the building on which the facade is arranged, via wall brackets or the like, and yet due to the possibility of profiles of the second layer to connect in a simple way with the metal profiles of the first layer, a variety of vertically aligned metal profiles of the second layer can be arranged to accommodate small-format facade panels 2. In addition, a facade according to the invention is also fire-resistant or meets current relevant guidelines, especially since wooden slats are no longer required to connect the mats 13 of the insulating material and the facade panels 2 to the wall 1 . In addition, due to the loose fit with which the screws 3 are arranged in the through holes 8 of the facade panels 2, there is also mobility in a plane perpendicular to an axis of the screws 3 or a plane of the facade panels 2, so that different thermal expansions of the metal profiles and the facade panel 2 can be easily compensated.
