In Fig.l ist die Außenwand 10 eines Gebäudes 1 dargestellt, an welcher mittels Tragelementen 2 eine Vorrichtung zur Befestigung von Fassadenplatten 6 vorgesehen ist, wobei diese Vorrichtung aus vertikal ausgerichteten und voneinander im Abstand befindlichen ersten Tragschienen 3 sowie an diesen befestigten, horizontal ausgerichteten und gleichfalls voneinander im Abstand befindlichen zweiten Tragschienen 4 besteht. Die Fassadenplatten 6 sind mittels Tragbügel 5 an den horizontal ausgerichteten zweiten Tragschienen 4 befestigt. Zwischen den Fassadenplatten 6 und der Außenwand 1 befindet sich eine Isolierung 60. Weiters befinden sich zwischen den vertikalen Rändern der Fassadenplatten 6 an den zweiten Tragschienen 4 befestigte Fugenleisten 61.In Fig.l the outer wall 10 of a building 1 is shown, on which by means of support elements 2, a device for fastening facade panels 6 is provided, this device consisting of vertically aligned and spaced apart first mounting rails 3 and attached to this, horizontally aligned and there is also a second spaced apart mounting rails 4. The facade panels 6 are fastened to the horizontally aligned second mounting rails 4 by means of mounting brackets 5. Insulation 60 is located between the facade panels 6 and the outer wall 1. Furthermore, joint strips 61 fastened to the second mounting rails 4 are located between the vertical edges of the facade panels 6.
Wie dies aus Fig.2 ersichtlich ist, bestehen die Tragelemente 2 aus einer ersten Tragplatte 21 , welche unter Zwischenlage einer Isolierung 20 an die Außenwand 10 anliegt und aus einer von dieser quer abragenden zweiten Tragplatte 22. Die erste Tragplatte 21 ist mittels Bolzen 23 an der Außenwand 10 befestigbar.As can be seen from FIG. 2, the support elements 2 consist of a first support plate 21, which lies against the outer wall 10 with the interposition of insulation 20, and of a second support plate 22 projecting transversely therefrom.

Gemäß einer in Fig.4 dargestellten zweiten Ausführungsform der zweiten Tragschienen 4a sind diese im Querschnitt als rechtwinkeliges Dreieck ausgebildet, wobei die erste Seitenwand 41 an die ersten Tragschienen 3 anliegt, die zweite Seitenwand 41c von der ersten Seitenwand 41 im rechten Winkel abragt und die dritte Seitenwand 41 d die Enden der beiden anderen Seiten- wände 41 und 41c diagonal verbindet. Weiters sind die zweiten Tragschienen 4a mit von den Seitenwänden 41 nach oben abragenden Fortsätzen 42a ausgebildet, welche mittels Schrauben 30 an den ersten Schienen 3 befestigbar sind.According to a second embodiment of the second mounting rails 4a shown in FIG. 4, these are designed in cross section as a right-angled triangle, the first side wall 41 abutting the first mounting rails 3, the second side wall 41c projecting from the first side wall 41 at a right angle and the third Side wall 41 d the ends of the other two side walls 41 and 41c diagonally. Furthermore, the second mounting rails 4a are formed with extensions 42a projecting upwards from the side walls 41, which can be fastened to the first rails 3 by means of screws 30.
Bei dieser Ausbildung der zweiten Tragschienen 4a sind nur die an deren Oberseite vorgesehenen Befestigungsschrauben 30 erforderlich, wodurch eine Vereinfachung in der Montage erzielt wird.In this embodiment of the second mounting rails 4a, only the fastening screws 30 provided on the upper side thereof are required, which simplifies assembly.
Die Seitenwände 41c sind an ihrer Oberseite mit nach oben abragenden Leisten 43a ausgebildet, welche von einem hakenförmigen Teil 52a von Tragbügeln 5a übergriffen sind. Weiters sind die zweiten Tragschienen 4a an ihrer der Seitenwand 41 gegenüberliegenden Seite mit einer Nut 44a ausgebildet, in welche ein von den Tragbügeln 5a quer abragender Steg 53a einragt. Zudem sind die Tragbügel 5a mit einem im Querschnitt H-förmigen Teil 54 ausgebildet, durch welche zwei Nuten 54a und 54b gebildet sind, in welche die unteren Enden 64a bzw. die oberen Enden 64b der Platten 6 einragen, wodurch die Platten 6 an den Tragschienen 5a befestigbar sind.The side walls 41c are formed on their upper side with upwardly projecting strips 43a which are overlapped by a hook-shaped part 52a by carrying brackets 5a. Furthermore, the second mounting rails 4a are formed on their side opposite the side wall 41 with a groove 44a, into which a web 53a protrudes transversely from the mounting brackets 5a. In addition, the support bracket 5a is formed with a part 54 which is H-shaped in cross section and through which two grooves 54a and 54b are formed, into which the lower ends 64a and the upper ends 64b of the plates 6 protrude, as a result of which the plates 6 on the support rails 5a are attachable.
Da die horizontal ausgerichteten zweiten Tragschienen 4, 4a im Querschnitt als dreieckige Hohlprofile ausgebildet sind, kommt ihnen eine sehr große Tragfestigkeit, insbesondere Torsionsfestigkeit, zu. Da weiters die zweiten Tragschienen 4, 4a gegenüber den ersten Tragschienen 3 verschiebbar befestigt sind und da weiters auch die zweiten Tragschienen 4, 4a und die Tragbügel 5, 5a gegeneinander verschiebbar sind, werden infolge von Wärmedehnungen der Tragschienen 3, 4 bzw. 4a bedingte Belastungen der Tragkonstruktion weitestgehend vermieden.Since the horizontally aligned second support rails 4, 4a are designed as triangular hollow profiles in cross section, they have a very high load capacity, in particular torsional strength. Furthermore, since the second mounting rails 4, 4a are slidably fastened with respect to the first mounting rails 3, and since the second mounting rails 4, 4a and the mounting brackets 5, 5a are also displaceable relative to one another, loads are caused as a result of thermal expansion of the mounting rails 3, 4 and 4a the supporting structure largely avoided.
Die in Fig.5 dargestellte dritte Ausführungsform unterscheidet sich von der in Fig. 3 dargestellten Ausführungsform dadurch, dass die zweiten Tragschienen 7, ebenso wie die Tragbügel 8 für die Fassadenplatten 6 eine geänderte Ausbildung aufweisen. Die Tragbügel 7 liegen mit einer ersten Seitenwand 71 an die ersten Tragschienen 3 an. An ihrem oberen Ende ist diese Seitenwand mit einem Haken 72 ausgebildet. Durch die beiden von der Seitenwand 71 abragenden Seitenwände 71a und 71b ist diese Tragschiene 7 im Querschnitt als gleichseitiges Dreieck ausgebildet, welche an deren der Seitenwand 71 gegenüberliegenden freien Ende mit einer quer abragenden Lei- ste 73 ausgebildet ist. Die Tragbügel 8 weisen einen ersten Schenkel 81 auf, welcher an die obere Seitenwand 71a anliegt und dessen freies Ende 82 in den Haken 72 einsetzbar ist. Weiters ist der Tragbügel 8 mit einem quer abragenden Fortsatz 83 ausgebildet, welcher hinter der Leiste 73 einsetzbar und in dieser Lage verr astbar ist. An seinem anderen Ende ist der Tragbügel 8 gleichfalls wiederum mit einem H-förmigen Teil 84 ausgebildet, welcher zwei Nuten 84a und 84b aufweist, in welche die unteren Enden 64a und die oberen Enden 64b der Platten 6 einsetzbar sind.The third embodiment shown in FIG. 5 differs from the embodiment shown in FIG. 3 in that the second mounting rails 7, like the mounting bracket 8 for the facade panels 6, have a different design. The support brackets 7 rest on the first support rails 3 with a first side wall 71. This side wall is formed with a hook 72 at its upper end. Due to the two side walls 71a and 71b projecting from the side wall 71, this support rail 7 is designed in cross section as an equilateral triangle, which at its free end opposite the side wall 71 has a transversely projecting line. ste 73 is formed. The support brackets 8 have a first leg 81 which bears against the upper side wall 71a and whose free end 82 can be inserted into the hook 72. Furthermore, the support bracket 8 is formed with a transversely projecting extension 83 which can be used behind the bar 73 and can be locked in this position. At its other end, the support bracket 8 is likewise in turn formed with an H-shaped part 84 which has two grooves 84a and 84b, into which the lower ends 64a and the upper ends 64b of the plates 6 can be inserted.
Die Tragschienen 7 und die Tragbügel 8 sind in den Fig.5a und 5b gegenüber der Fig.5 vergrößert dargestellt. In Fig. 5a ist der Tragbügel 8 in seiner mit der Tragschiene 7 nicht verriegelten Lage und in Fig. 5b in seiner mit der Tragschiene 7 verriegelten Lage dargestellt. Wie dies aus diesen Darstellungen weiters ersichtlich ist, ist der Fortsatz 83 des Tragbügels 8 mit einer nach unten abragenden Nase 83a ausgebildet, welcher an der Leiste 73 eine nach innen abragende Nase 73a zugeordnet ist.The mounting rails 7 and the mounting bracket 8 are shown in FIGS. 5a and 5b enlarged compared to FIG. 5a shows the support bracket 8 in its position not locked with the support rail 7 and in FIG. 5b in its position locked with the support rail 7. As can also be seen from these representations, the extension 83 of the support bracket 8 is formed with a downwardly projecting nose 83a, which is assigned an inwardly projecting nose 73a on the bar 73.
Zur Befestigung der Tragbügel 8 in den Tragschienen 7 wird der Fortsatz 82 in den Haken 72 eingesetzt und wird in der Folge der Tragbügel 8 nach unten verschwenkt. Hierdurch gelangt der Fortsatz 82 hinter die Leiste 73, wobei die Nase 83a unter die Nase 73a gelangt. Hierdurch werden die Tragbügel 8 in den Tragschienen 7 verrastet. Durch diese konstruktive Gestaltung ist eine sehr einfache und dessen ungeachtet den technischen Erfordernissen entsprechend starre Befestigung möglich. To fasten the support bracket 8 in the support rails 7, the extension 82 is inserted into the hook 72 and the support bracket 8 is subsequently pivoted downward. As a result, the extension 82 passes behind the bar 73, the nose 83a reaching under the nose 73a. As a result, the mounting bracket 8 are locked in the mounting rails 7. This constructive design enables a very simple and, regardless of the technical requirements, rigid attachment.
