Abstract
A sound insulation floor structure comprises a floor backing member, a floor finishing layer, and an intermediate layer between the floor backing member and the floor finishing layer, the intermediate layer comprising a buffer member comprising a nonwoven structure. The nonwoven structure comprises a thermal adhesive fiber under moisture which is melt-bonded to a fiber of the nonwoven structure to fix the fibers. For example, the sound insulation floor structure may comprise, in sequence, a floor backing member, a buffer layer, an air layer, a hard layer, and a floor finishing layer. In the floor structure, a support memberis disposed between the buffer layerand the hard layer. The support member may occupy 10 to 70% of a floor area. The sound insulation floor structure prevents subsidence of a floor member due to walking, achieves comfortableness to walk, and has improved floor impact sound insulation.
