Tube wall made of tubes which extend parallel to one another and horizontal to inclined

Claim 1

A tube wall suspendable from a supporting structure for assuming the forces resulting from the dead weight of the tube wall and from additional loads, comprising a plurality of tubes extending parallel to one another and horizontal to inclined, said tubes include oppositely directed fins, the latter having longitudinal edges welded gas-tight respectively to one another, adjacent of said tubes thereby being operatively welded gas-tight to one another, said fins, respectively, being formed as a continuous band having a width exceeding the outer diameter of said tubes, respectively, said band being connected tangentially on an outerside of said tube, respectively, such that the thickness of the connection is at least as thick as the sum of the thickness of the tube and band, said bands being adapted to be suspended from the supporting structure, a tension chord forming one-piece with said tubes and constituting said band, the latter having a surface facing said tubes substantially tangentially aligned with the adjacent imaginary outer periphery of said tubes.
