PROBLEM TO BE SOLVED: To provide a floor slab structure which reduces manufacturing costs, has high fatigue strength, allows section stiffness to be selected by a filler with which the inside of a floor slab is to be filled, and can prevent the freezing of a road surface. SOLUTION: A sandwiched floor slab structure is characterized in that an intermediate corrugated steel plate 4 is bound to upper and lower steel plates 2 and 3, which are vertically arranged in parallel and coupled together with a coupler 6, by nonwelding, while being sandwiched between the steel plates 2 and 3 in a state in which corrugated top parts abut on the steel plates 2 and 3, respectively. An upper or lower corrugated space of the floor slab 1 can also be filled with a curable filler and a thermal storage filler. COPYRIGHT: (C)2004,JPO |
