Title:
FLOOR STRUCTURE
Document Type and Number:
Japanese Patent JP2010180575
Kind Code:
A
Abstract:

To provide a floor structure excelling in floor impact sound cut-off performance and improving workability.

An upper floor material 14 is supported on a sleeper 30 through joists 32, and elastic members 40 of dynamic vibration absorbers 34 are supported to the sleeper 30 through mounting bolts 38 or the like. Consequently, when vibration is applied to the upper floor material 14, the vibration is transmitted to the elastic members 40 of the dynamic vibration absorbers 34 through the joists 32, the sleeper 30 and the mounting bolts 38 or the like. The elastic members 40 of the dynamic vibration absorbers 34 are thereby deformed elastically, and mass bodies 42 supported by the elastic members 40 in the dynamic vibration absorbers 34 are vertically moved to absorb the vibration to thereby damp the vibration from the upper floor material 14 to a floor slab 12.
