SOUND INSULATION FLOOR STRUCTURE AND SOUND INSULATION FLOOR COMPONENTS AS WELL AS METHOD FOR REDUCING FLOOR IMPACT SOUNDS

Document Type and Number:

WIPO Patent Application WO/2011/111608

Kind Code:

A1

Abstract:

Intermediate layers including shock absorbing members formed of nonwoven fiber structures are interposed between a floor substrate member and a floor finish layer, resulting in a sound insulation floor structure being formed. Structures which contain moist heat adhesive fibers and wherein fibers are fixed by the fusion of these moist heat adhesive fibers, are used as said nonwoven fiber structures. As regards such a sound insulation floor structure, it is permissible, for example, to successively laminate a shock absorbing layer (2), a blank layer (3), a hard layer (4), and a floor finish layer (5) over the floor substrate member (1). In said structure, support members (6) exist between the shock absorbing layer (2) and the hard layer (4). The total area of the support members may account for 10 to 70% of the floor area. This sound insulation floor structure is such that the sinking of floor members due to walking is restricted, resulting in a satisfactory walking feeling being obtained, and that there is high performance for insulating floor impact sounds.
