BRIDGE AND METHOD FOR MANUFACTURING THE BRIDGE

摘要

The bridge is constructed of one inner tube (2) and an outer tube (1) sur rounding the inner tube (2). The inner and outer tube (1, 2) are joined to e ach other by connecting pipes (3 - 13) welded to the outer surface of the in ner tube (2) and to the inner surface of the outer tube (1) so that the inne r tube (2) and the outer tube (1) are connected to each other through said c onnecting pipes (3 - 13) whereby a rigid composite structure is formed. The tubes and pipes are preferably laser welded to each other, preferably by a c ontinuous seam.
