<p>PROBLEM TO BE SOLVED: To provide a flooring material and a floor structure of a building, easily constructible at a low cost, and capable of easily adjusting a soundproof performance level.SOLUTION: A floor structure 1 comprises a flooring material 4 supported on a sleeper (a structure) 2 of the building via a floor joist (an intermediate member) 3, and the flooring material 4 includes a first wooden part 41 provided on the floor surface side, a second wooden part 42 provided on the reverse surface side on the opposite side of a floor surface and a viscoelastic member 43 sandwiched between the first wooden part 41 and the second wooden part 42. Since the first wooden part 41, the second wooden part 42 and the viscoelastic member 43 are mutually integrally adhered, damping force of the viscoelastic member 43 is exhibited to a load of acting on the flooring material 4, and impact noise can be reduced by damping vibration of the flooring material 4 by this damping force.</p> |
