FILLING CONCRETE FALL PREVENTION MECHANISM IN CONCRETE BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a filling concrete fall prevention mechanism in a concrete bridge capable of preventing the fall of collapsed concrete pieces and a steel plate by bearing the steel plate laid between PC girders by uniform force. SOLUTION: The mechanism includes a fall prevention plate 4 mounted between the PC girders 1 so as to cover the bottom of the filling concrete, a string-like supporting material 6 located downward of the fall prevention plate 4 and stretched between horizontal girders 5 constructed for connecting each PC girder 1 and a plurality of vertical supporting materials 9 vertically arranged so that the string-like supporting material 6 can be successively getting longer toward the center of each horizontal girder 5 required to be stretched in an arched shape between the fall prevention plate 4 and the string-like supporting material 6.
