SOLUTION: The joint member 10 is embedded in notches 8, 8 each formed in an upper portion of an edge of a bridge body (a bridge girder or a bridge abutment) which is arranged in a manner opposed to a counterpart across an expansion gap 4 at the midpoint or the edge of the bridge 1, in a manner slidable by means of a simple bearing or a plate. The joint member is made of high-toughness fiber-reinforced cement 11 which is obtained by blending Vinylon fibers etc. in a cement matrix, exhibits large pseudo-extensibility caused by cracking and dispersion, and has a suitable rigidity withstanding wheel loads. Then the joint member 10 is connected to the bridge body in one body by means of stress transfer members, anchors, couplers, etc.

摘要： PROBLEM TO BE SOLVED: To fabricate a shear reinforcing bar by joining a steel bar such as a reinforcing bar with a locking plate made of flat steel efficiently with a small welding device.
SOLUTION: A pair of cramp means 4 are arranged facing each other so as to sandwich a pair of fixing stands 3, which are prepared at the central part in the longitudinal direction of a base 2, and a steel bar 6 cramped by the cramp means 4 is pressure-welded from both sides with a locking plate 7 held by the pair of fixing stands 3. Thus, the pressure applied to the pair of fixing stands 3 is canceled each other so that the fixing stands 3 does not require a large and strong structure and can be miniaturized. While a plurality of locking plates 7 are held by the fixing stands 3, a plurality of steel bars 6 are cramped by cramp means 4, and they are joined to the locking plates 7 at one time so that joining efficiency is improved.
