CONSTITUTION:An arm 5 rotatably supported by the support member 11 of a lower chord 3 constituting a truss 1 is connected to an upper chord 2 via a wire rope 17. A suspended scaffold 6 is fitted to the field-assembled truss 1 in the folded state, it is suspended at the preset position by a crane or the like, the suspended scaffold 6 is utilized to fix the upper and lower chords 2 and 3 to pillars, and a sub-truss 21 is suspended and temporarily-tightened to the truss 1.
