Title:
VIBRATION INSULATION AND SOUND INSULATION FLOOR STRUCTURE
Document Type and Number:
Japanese Patent JP2018178502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration insulation and sound insulation floor structure capable of reducing propagation of floor impact sound, generated by an upstairs floor, to a downstairs floor by improving weight floor impact sound insulating performance of a wooden building.SOLUTION: A vibration insulation and sound insulation floor structure 10 is provided at a floor part between an upper story 30 and a lower story 31 of a wooden building, and includes a floor substrate material 12 supported by floor support members 11a, 11b and laid on upper surfaces of the floor support members 11a, 11b, a sheet-like floating floor material 13 overlaid on an upper surface of the floor substrate material 12, and a heavy floor panel material 14 overlaid on an upper surface of the sheet-like floating floor material 13. The sheet-like floating floor material 13 forms a vibration insulation layer 16 which bears a load from the heavy floor panel material 14 in an elastically deformable state to suppress vibration from the heavy floor panel material 14 from reaching the floor substrate material 12. The heavy floor panel material 14 is formed by laying a plurality of unit floor panel members 15 side by side longitudinally and laterally on the upper surface of the sheet-like floating floor material 13.SELECTED DRAWING: Figure 1
