Pleated steel construction mounted on three columns. Vaulted main beams run radially (spoke-shaped) to the peripheral beams. The main beams are reinforced by longitudinal and transverse ribs. The underside of the roof is made of supporting steel. The roof is drained via an open edge groove designed as a gutter. The water collects at the two lowest points from where it is drained via the columns into the sewage system. Since the two lowest points on the outer sides of the roof are below the lowest column drainage point, they are additionally drained via spouts.
