Abstract

The cover (1) has a frame (5) connected to the opening formed on a building roof, blades (2) that move between closed and open position, and smoke deflection walls (3) for reducing cross-wind effect in the interchange of air through the roof opening. The walls move between start position (8) in which the walls are perpendicular to the roof surface, and smoke deflection position in which the walls exceed the height of the frame.

Description

Für die Rauch- und Wärmeabführung im Brandfall sind für bestimmte Gebäudearten sogenannte Rauch- und Wärmeabzugsanlagen vorgeschrieben. Ein wesentlicher Bestandteil dieser Anlagen ist vor allem die Abzugsklappe (1) im Deckenbereich. Ein wichtiger Aspekt bei diesen Klappen ist die aerodynamische Wirkung. Das bedeutet, dass die Abzugsklappe (1) bei einer bestimmten Größe, einer bestimmten Öffnungsweite des Flügels (2), und einer bestimmten Einbaulage auf dem Dach einen möglichst guten Wirkungsgrad haben sollte. Dies ist deshalb wichtig da gesetzliche Forderungen für einen bestimmten Gebäudebereich eine definierte aerodynamisch wirksame Öffnungsfläche vorschreiben. Je nach Wirkungsgrad der Klappen (1) müssen hier entsprechend viele solcher Anlagen eingebaut werden. Klappensysteme mit einem besonders guten Wirkungsgrad sind durch einen hohen Aufsatzkranz, durch eine sehr große Öffnungsweite und durch das Vorhandensein von Windleitwänden (3) gekennzeichnet. Diese Ausführung ist natürlich bei den Architekten bei der Konzeption eines Glasdaches nicht tragbar. Hier sollen die Abzugsklappen (1) möglichst flach sein, es sollen natürlich auch keine nach oben überstehende Windleitwände (3) vorhanden sein, und die Öffnungsweiten sollen ebenfalls kleiner sein um kleinere Motoren (4) einbauen zu können. Diese Ausführung hat den gravierenden Nachteile das der Wirkungsgrad sehr schlecht ist. Dies kann dann nur durch den Einbau von zusätzlichen Klappen (1) ausgeglichen werden. Unser Erfindung löst dieses Problem folgendermaßen:
Die Ausführung der RWA-Abzugsklappe (1) entspricht äußerlich der eines Lüftungsflügels für Glasdächer, und besitzt im geschlossenen Zustand keine sichtbaren bzw. nach oben stehenden Windleitwände (3). Wird der RWA-Flügel (2) geöffnet klappen oder schwenken mittels einer Zwangssteuerung an den Seiten bzw. an der Vorderseite Windleitwände (3) heraus die bei Seitenwind die aerodynamische Wirkung der RWA-Klappe (1) verbessern. Diese zusätzlichen Bleche (3) sind an der Innenseite der Rahmenprofile (5) angeordnet, oder können aber auch in einer Zwischenkammer untergebracht sein damit sie auch von innen nicht sichtbar sind. Diese Bleche (3) können entweder durch Gelenke (6) (5) oder Längsführungen (7) (3 und 4) nach oben herausgefahren oder herausgeschwenkt werden. Die Bleche (3) können einteilig oder auch mehrteilig ausgeführt sein. Durch entsprechende Anordnung und Höhe der Windleitwände (3) kann die Funktion besonders bei Seitenwind wesentlich verbessert werden.For the smoke and heat dissipation in case of fire so-called smoke and heat exhaust ventilation systems are required for certain types of buildings. An essential component of these systems is above all the exhaust flap ( 1 ) in the ceiling area. An important aspect of these valves is the aerodynamic effect. This means that the exhaust flap ( 1 ) at a certain size, a certain opening of the wing ( 2 ), and a certain installation position on the roof should have the best possible efficiency. This is important because legal requirements for a certain building area prescribe a defined aerodynamically effective opening area. Depending on the efficiency of the flaps ( 1 ), a corresponding number of such systems must be installed here. Flap systems with a particularly good efficiency are characterized by a high curb, by a very large opening width and by the presence of Windleitwänden ( 3 ). Of course, this design is not acceptable to the architects when designing a glass roof. Here are the flaps ( 1 ) be as flat as possible, it should of course not upwardly projecting wind deflectors ( 3 ) and the opening widths should also be smaller around smaller motors ( 4 ) to install. This design has the serious disadvantages that the efficiency is very poor. This can then only by the installation of additional flaps ( 1 ). Our invention solves this problem as follows:
The design of the RWA exhaust flap ( 1 ) corresponds externally of a ventilation wing for glass roofs, and has in the closed state no visible or upward Windleitwände ( 3 ). If the RWA wing ( 2 ) open or pivot by means of a forced control on the sides or at the front wind deflectors ( 3 ) in the crosswind the aerodynamic effect of the SHE flap ( 1 ) improve. These additional sheets ( 3 ) are on the inside of the frame profiles ( 5 ), or can also be accommodated in an intermediate chamber so that they are not visible from the inside. These sheets ( 3 ) can be either through joints ( 6 ) ( 5 ) or longitudinal guides ( 7 ) ( 3 and 4 ) are moved outwards or swung out. The sheets ( 3 ) can be made in one piece or in several parts. By appropriate arrangement and height of the wind deflectors ( 3 ), the function can be significantly improved, especially in crosswinds.

In einer weitere Ausgestaltung der Erfindung kann das Ausklappen der Windleitwände (3) auch in der Weise erfolgen, das im Lüftungsbetrieb z.B. bis zu einer Öffnungsweite von 40 Grad die Windleitbleche (3) in ihrer Parkposition (8) bleiben, und erst bei weiterem Öffnen z.B. bei 70 Grad in die RWA-Position (9) gezogen werden. Im geschlossenen oder Lüftungszustand sieht die Abzugsklappe (1) wie ein normaler Lüftungsflügel aus. Die Windleitwände (3) können aus verschiedenartigem Material, wie z.B. aus Stahlblech, aus Kunststoff oder auch aus Glas bestehen.In a further embodiment of the invention, the unfolding of the wind deflectors ( 3 ) also be carried out in the manner that in ventilation operation, for example up to an opening width of 40 degrees, the wind deflectors ( 3 ) in their parking position ( 8th ), and only on further opening eg at 70 degrees in the RWA position ( 9 ) to be pulled. In the closed or ventilation state, the exhaust flap ( 1 ) like a normal ventilation wing. The wind deflectors ( 3 ) can be made of various materials, such as sheet steel, plastic or glass.
