<p>A hollow body is made up from individual tube elements having groove and tongue connections constructed in their ends. The tube ends also carry flanges disposed on the outside and/or inside thereof, the flanges each having an oblique rear surface so that the flange width increases towards the base of the flange. The two flanges of confronting tube ends are overlapped by a ring which has an inner ring channel, the side edges of which enclose both flanges in the manner of a clamp. The distance between these side edges when they are in the unstressed state is shorter than the distance between the base points of the two oblique surfaces. The ring abuts the outer sides of the tubes and can be tightened by a clamping device. The tube elements may each be formed by a plurality of sectional shells.</p> |
