PROBLEM TO BE SOLVED: To provide a vibration control floor structure capable of reducing vibration propagating to the periphery from the inside of a building and vibration propagating to the inside of the building from the building periphery by use of minimum support piles. SOLUTION: A floor slab 18 isolated from a structure 12 and the ground 16 is arranged in the structure 12 in a state of being supported on a support base 22 by a support member 20, and since a vibration cutoff means 26 is arranged in the support member 20 for cutting off the transmission to the ground 16, the vibration propagating to the periphery of the structure 12 from a floor slab 18 in the structure 12 having a vibration generating source A can be reduced. Since the support member 20 is required to support only the floor slab 18 having the vibration generating source A, the vibration reducing effect can be provided by a small number of support members 20 having a small cross section (a small diameter).
