Abstract

Projection wall systems having projection walls are used, for example, for cinema screens or planetariums. They are provided in the form of cupola-shaped, dome-like superstructures, which have an exterior supporting structure and, on the inside, have a primarily concave surface that is used as a projection wall for special cinema projectors. The inventive device is a projection wall system comprising a projection wall with a simplified design, whereby segment constructional units (13) are fastened to a supporting structure (199) by means of retaining elements (222) provided with adjusting devices.
