FLOATING SLAB EXECUTING METHOD AND ITS SUPPORTING STRUCTURE

PURPOSE:To simply execute a floating slab serving as a roadbed for an electric car and a vehicle without requiring a wide place by using a vibration-proof rubber core body and an extensile levelling jig, and to make the floating slab vibration-proof and its exchange easy by applying the vibration-proof rubber core body. CONSTITUTION:A floating slab executing method is to insert an extensile levelling jig 10 between a slab sleeve 2 buried in a slab concrete 1 and a vibration- proof rubber core body 5 for raising a slab, and then to fittedly insert a wedge member 6 between them for holding the slab. In a floating slab supporting structure, the vibration-proof rubber core body 5 is formed about into a truncated cone-shape by inserting a vibration-proof rubber 5c between a double ring, and the vibration-proof rubber core body 5 is arranged in the through hole Ia of the slab concrete, and a wedge member 6 is inserted between the inner wall of the through hole 1a and the vibration-proof rubber core body 5 to support the slab.
