PROBLEM TO BE SOLVED: To provide a stopper mechanism capable of preventing the disposed position of a steel plate panel for a composite floor slab from coming out of the range of a proper position while preventing an excessive internal stress from being introduced into the steel plate panel or the steel plate panel from being deformed even if an unexpected horizontal force in the direction perpendicular to a bridge axis acts on the steel plate panel before a floor slab concrete is hardened after the steel plate panel is installed on a steel girder.SOLUTION: This stopper mechanism includes stoppers 12, 14 which are installed on the upper surface of the steel girder 62 while providing predetermined expansion gaps s1, s2 between themselves and a support member 60 in the direction perpendicular to the bridge axis, respectively. The stopper mechanism allows the movement of the steel plate panel 50 equal to or shorter than the predetermined gaps s1, s2 in the direction perpendicular to the bridge axis but does not allow the movement thereof exceeding the predetermined gaps s1, s2. |
