Abstract

Das System zeichnet sich durch eine flache, maximal 28°, Aufständerung aus. Hierdurch wird eine möglichst geringe Angriffsfläche für die Windlasten geboten. Windverwirbelungen sichern das System durch die Anpressdrücke, die entweder auf dem Modul entstehen, oder auf dem Aerodynamikblech. Diese Anpresskräfte sorgen für einen sicheren Stand der Anlage, welche zu geringeren Beschwerungen führen und dadurch die durchschnittliche Dachlast senken.The system is characterized by a flat, maximum 28 °, elevation. As a result, the smallest possible contact surface for the wind loads is offered. Wind turbulences secure the system through the contact pressures that arise either on the module or on the aerodynamic sheet. These pressing forces ensure that the system is in a safe position, which leads to lower loads and thus reduces the average roof load.

Description

Das Flachdach-Montagesystem „Vario Ultra Light” besteht vollständig als Aluminium und Edelstahl um eine dauerhafte Witterungsbeständigkeit gewährleisten zu können. Hierzu werden Aufstellwinkel auf ein Aluminiumprofil geschraubt, welches durch Bautenschutzmatten und Fließ von der Dachhaut getrennt auf dem Dach aufgestellt werden. Für diese Montage sind keinerlei Dachdurchdringungen notwendig! Die Photovoltaik-Module werden einfach zwischen zwei Aufstellwinkel in eine U-Führung eingeschoben und dann an der oberen Kante durch umknicken einer Lasche gesichert. Auf der Rückseite befindet sich ein Aerodynamikblech, welches das ganze System stabilisiert. Durch diese Konstruktion wird die gesamte Anlage aerodynamisch optimiert, so dass geringe bis keine Auftriebskräfte entstehen, wodurch wiederum keine weiteren Beschwerungen benötigt werden. Übliche Einschränkungen sind die Begrenzung der Auflasten durch die jeweilige Gebäudestatik und die vorhandenen Lastreserven.The flat roof mounting system "Vario Ultra Light" is made entirely of aluminum and stainless steel to ensure lasting weather resistance. For this purpose, installation angles are screwed onto an aluminum profile, which are set up on the roof separated from the roof by building protection mats and fleece. No roof penetrations are necessary for this installation! The photovoltaic modules are simply inserted between two installation angles in a U-guide and then secured at the top edge by folding over a tab. On the back is an aerodynamic sheet, which stabilizes the whole system. This construction aerodynamically optimizes the entire system so that little to no buoyancy forces arise, which in turn requires no further weighting. Usual restrictions are the limitation of the loads by the respective building statics and the available load reserves.

Ein weiteres Problem bei herkömmlichen Systemen ist ein Montieren mit vielen einzelnen Bauteilen, Modulklemmen, Schrauben, Nutensteinen usw.Another problem with conventional systems is mounting with many individual components, module clamps, screws, sliding blocks, etc.

Schutzanspruch 1 bezieht sich auf das Problem, dass übliche Montagesysteme eine große Angriffsfläche für Windverwirbelungen bieten, oder diese durch hohe Aufstellwinkel sogar verstärken.Protection claim 1 refers to the problem that conventional mounting systems offer a large attack surface for wind turbulence, or even increase it by high installation angle.

Der Schutzanspruch 1 liegt in der aerodynamischen Form des Systems und vor allem des Aerodynamikbleches.The protection claim 1 lies in the aerodynamic shape of the system and especially the aerodynamic sheet.

Ein Problem bei Montagesystemen ist die geringe Aufnahmefähigkeit von Querkräften. Also Kräften die in Modulreihenrichtung auftreten.A problem with mounting systems is the low absorption capacity of shear forces. So forces that occur in module row direction.

Im Schutzanspruch 2 geht es um die Aufnahme von Querkräften durch das Aerodynamikblech, welches sich hinter den Modulen befindet.In protection claim 2 is about the absorption of shear forces through the aerodynamic sheet, which is located behind the modules.

Ähnliche Systeme wie das „Vario Ultra Light” bieten ebenfalls ein Rückblech an, um einen aerodynamischen Vorteil zu erzielen. Bei diesen Blechen prallt der Wind ab, es kommt zu geringen Vorteilen was die Aerodynamik angeht, aber die Schubkräfte nehmen erheblich zu,Similar systems like the "Vario Ultra Light" also offer a back plate for aerodynamic benefit. With these sheets, the wind bounces off, it comes to low benefits in terms of aerodynamics, but the shear forces increase significantly,

Im Schutzanspruch 3 handelt es sich um einige dreieckige Ausnehmungen. Ihre Lage und Form gestattet einen kontrollierten Einlass von Wind unter die Module.The protection claim 3 is a few triangular recesses. Their position and shape allows a controlled inlet of wind under the modules.

Die meisten Montagesysteme verschrauben die Module mit Hilfe von Modulklemmen. Dieses ist Zeit- und Geld-Aufwendig.Most mounting systems screw the modules together using module clamps. This is time and money-consuming.

Im Schutzanspruch 4 ist zu sehen, dass die Module frei innerhalb des Aufstellwinkels liegen und mittels zweier Laschen ausreichend gesichert werden.In protection claim 4 it can be seen that the modules are free within the installation angle and sufficiently secured by two tabs.

Claims (4)

Das System zeichnet sich durch eine flache, maximal 28°, Aufständerung aus. Hierdurch wird eine möglichst geringe Angriffsfläche für die Windlasten geboten. Windverwirbelungen sichern das System durch die Anpressdrücke, die entweder auf dem Modul entstehen, oder auf dem Aerodynamikblech. Diese Anpresskräfte sorgen für einen sicheren Stand der Anlage, welche zu geringeren Beschwerungen führen und dadurch die durchschnittliche Dachlast senken.The system is characterized by a flat, maximum 28 °, elevation. As a result, the lowest possible attack surface for the wind loads is offered. Wind turbulences secure the system by the contact pressures that arise either on the module or on the aerodynamic sheet. These contact forces ensure a secure position of the system, which leads to lower weighting and thereby lower the average roof load. Das Aerodynamikblech stützt das gesamte „Vario Ultra Light” gegen knicken, indem das Blech die auftretenden Querkräfte aufnimmt und auf die Unterkonstruktion weiterleitet.The aerodynamic sheet supports the entire "Vario Ultra Light" against kinking, as the sheet absorbs the transverse forces and transfers them to the substructure. Die dreieckigen Ausnehmungen in dem Aerodynamikblech entlasten das gesamte Montagesystem, indem kontrolliert der angestaute Winddruck unter die Module abgeleitet wird. Dieses bietet einen großen Vorteil, da die entstehenden Kräfte aus dem Staudruck abgebaut werden und das System weniger Schubkräfte aufnehmen muss. Dieses verringert die benötigte zusätzliche Beschwerung bzw. sorgt dafür, dass keinerlei zusätzliche Beschwerung eingesetzt werden muss. Ein zusätzlich positiver Nebeneffekt ist der, dass die durch die Luftströmung erzeugten Auftriebskräfte an den Modulen verringert werden.The triangular recesses in the aerodynamic sheet relieve the entire assembly system by controlling the accumulated wind pressure is discharged under the modules. This offers a great advantage as the resulting forces are reduced by the dynamic pressure and the system has to absorb less thrust. This reduces the additional weight required or ensures that no additional weighting must be used. An additional positive side effect is that the buoyancy forces generated by the air flow on the modules are reduced. Die Module werden einfach in die Aufstellwinkel geschoben und mit Hilfe von umgebogenen Laschen gesichert. Diese Art der Befestigung ist ohne jegliches Werkzeug möglich und dazu noch sehr schnell und einfach zu realisieren. Sobald das Modul eingeschoben ist, wird die obere Lasche am rechten und linken Aufstellwinkel von Hand umgebogen. Die Lasche sorgt für eine formschlüssige Sicherung und das Modul kann Spannungsfrei gesichert werden.The modules are simply pushed into the installation angles and secured with the help of bent tabs. This type of attachment is possible without any tools and also very fast and easy to implement. As soon as the module is pushed in, the upper flap on the right and left installation angles is folded by hand. The tab provides a positive locking and the module can be secured tension-free.
