At least two wall segments (2,3) arranged adjacent to each other. A sealing member (15) which bridges the gap between the end sides (6,7) of the segments, is placed in opposing receiving channels (11). The ratio of the distance between two opposing channel walls (14) of a respective receiving channel, measured from the base (12) of the channel, and the thickness of the sealing member is greater than or equal to 1.1. |
