Description

In the inner courtyard of the Chamber of Commerce at Würzburg three extraordinary umbrellas were installed, offering an impressing sight. Each umbrella has a height of approximately 13 m and the total covered area is approximately 475 m². The biggest umbrella has an edge length of 14 m x 14 m. The funnel shape, which often is used in desert areas to collect rain, also has the advantage that it can drain the surface rain via the posts. Thus, costly drainage systems are avoided.
The main sub-structure of the roof consists of clamped steel posts and a fine frame fixed on the posts by horizontal and sloped struts. The extremely demanding tensioning process of the posts was carried out via the top plate into the ceiling of the underground parking directly beneath.
Due to the use of ETFE-foil for these umbrellas their appearance is very filigree and light. A cable net integrated in the ETFE-foils transmits the external loading to the frame and post.
