STEEL-CONCRETE SYNTHETIC FLOOR SLAB AND SYNTHETIC FLOOR SLAB BRIDGE USING STEEL SHEET PILE, AND CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To provide a steel-concrete synthetic floor slab and a synthetic floor slab bridge using steel sheet piles that easily prevent a leak of mortar in construction of a floor slab and a floor slab bridge, and to provide a construction method for the synthetic floor slab and the synthetic floor slab bridge. SOLUTION: A plurality of steel sheet piles 1 each having joints 5 on its lateral side edges are arranged in a row, and concrete 12 is placed and solidified at least in recessions 11 formed between rowed steel sheet piles 1 adjacent to each other to integrate together the row of steel sheet piles 1 to construct the steel-concrete synthetic floor slab. A leak preventing connection member 13 preventing a concrete leak is provided to bridge a gap between joints 5 of steel sheet piles 1 laterally adjacent to each other, and the concrete 12 is placed to bury each leak preventing connection member 13 therein. The steel sheet piles 1 is provided as a hat-shaped steel sheet pile, a U-shaped steel sheet pile, or a Z-shaped steel sheet pile. The leak preventing connection member 13 is provided as a strip of an elastic material, a thin plate, a steel plate, etc. COPYRIGHT: (C)2009,JPO&INPIT
