VENTILATION STRUCTURE FOR A WALL OPENING OF A FUNCTIONAL BUILDING, FUNCTIONAL BUILDING COMPRISING A VENTILATION STRUCTURE AND METHOD FOR INSTALLING AND / OR OPERATING A VENTILATION STRUCTURE FOR A WALL OPENING OF A FUNCTIONAL BUILDING

摘要

The invention relates to a ventilation structure for a wall opening of a functional building, a functional building with a ventilation structure and a method for installing and / or operating a ventilation structure for a wall opening of a functional building. The ventilation structure comprises at least one horizontally oriented shaft and a plurality of cover elements which are arranged in a rotationally fixed manner on the at least one horizontally oriented shaft. The ventilation structure further comprises at least one bearing for rotatably fastening the at least one shaft to the functional building. The at least one shaft has a reduced cross-sectional area at least in sections. The at least one bearing is arranged in a partial section of the shaft with a reduced cross-sectional area.
