PROBLEM TO BE SOLVED: To keep a buffer function against repeated load inputs from a vehicle and thus prevent electric corrosion with bridge girders and damages caused by the bridge girders. SOLUTION: A plurality of floor slab components 12, 12 of extruded shapes of aluminum alloys with each longitudinal hollow part 13 are arranged across a plurality of parallel girders 1, 1, at right angles, and a plurality of dowels 24 vertically fixed on the upper surface of the girder 1 are inserted into the hollow parts 13 through insertion holes 19 formed in lower plates 18 of the plurality of the floor slab components 12, and further, mortar M is filled into the hollow parts 13 of the floor slab component 12 which are fitted with the plurality of the dowels 24 and spaces between the insertion holes 19 and the upper surface of the girder 1 and then solidified. Thus, an installation structure for floor slab 10 is formed. COPYRIGHT: (C)2004,JPO
