PROBLEM TO BE SOLVED: To facilitate the connecting work of unit rail materials by providing connecting plates on the unit rail materials protrusively outward from their ends, and connecting the connecting plates through a connecting tool with the ends abutting each other. ;SOLUTION: Connecting members 84L, 84R are arranged on lateral connecting-side ends of a unit rail material 80. The connecting member 84L is formed of a connecting plate 84a, a flange 84b and a rib 84c. The connecting member 84R is constituted symmetrically. According to the above structure, the flanges 84b, 84b of both the connecting members 84L, 84R form a substantially square connecting flange 85 as the whole in the connecting ends of the unit rail materials 80. The connecting members 84L, 84R are preliminarily fixed to the unit rail materials 80 by bolts 26a and nuts 27a in the factory production step. Accordingly, the connection of the two unit rail materials 80 can be attained only by making the respective connecting flanges 85, 85 to abut each other, and fastening nuts 27 to bolts 26 inserted to a plurality of holes 84d, 84d.;COPYRIGHT: (C)2000,JPO
