PROBLEM TO BE SOLVED: To provide a floor structure that offers excellent cushioning property at a central side of a floor of a room or a corridor, for mitigating an impact from falling, and is also capable of suppressing sinking at a peripheral part of the floor of the room or the corridor, at the same time offering enhanced impact noise reduction property for a light-weight floor and absorbing unevenness of a slab surface.SOLUTION: A floor structure 1 includes a floor slab 2, an unevenness absorbing layer 3, a substrate layer 4, and a floor finishing layer 5. An unevenness absorbing layer part formed below the floor finishing layer 5 at a peripheral part of a room or a corridor is formed as an unevenness absorbing layer 6 having rubber for absorbing unevenness of a slab surface, while an unevenness absorbing layer formed below the floor finishing layer 5 at a central side other than the peripheral part of the room or the corridor is formed as an unevenness absorbing layer 7 having an inorganic fiber for absorbing unevenness of a slab surface 21. The unevenness absorbing layer with rubber includes a plurality of rubber block bodies 63 mounted on the slab surface and having a plurality of protrusions 64 for absorbing unevenness of the slab surface, and a plate part 61 installed over the plurality of rubber block bodies laid with an interval in between.SELECTED DRAWING: Figure 1 |
