PROBLEM TO BE SOLVED: To decrease the number of parts, to facilitate manufacturing and installation and to reduce man-hours by bending both ends of a diagonal material disposed between a top cord and a bottom chord to form in an S-shape, and joining the diagonal members to each other to dispose with a gusset plate. SOLUTION: A diagonal member 1 connecting a top cord 2 provided on the back of a bridge floor system to a bottom chord formed by a PC steel wire or the like is formed by bending both ends of an H-steel or the like to be S-shaped, and installing a connecting flange plate or the like at the end part. The top chord 2 and the bottom chord 3 are connected by the diagonal member 1 to construct a truss structure. In this case, the diagonal members 1 are directly connected to each other to be continuous, and the joint part is firmly fixed by a fastening member such as a bolt or the like. In the case where the bottom chord 3 is only a PC steel wire, a cable band is fitted to the PC steel wire 3, and the diagonal member 1 is joined thereto to constitute a structure. The number of parts can be remarkably reduced, Thus, the term of works can be shortened.
