Document Type and Number:
Japanese Patent JP3852343
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a double floor, a sound insulating floor, and a sound insulating floor construction method capable of strengthening mechanical strength, and capable of reducing a floor impulsive sound level when forming the sound insulating floor of a plurality of backing panels.
SOLUTION: The plurality of backing panels for forming the sound insulating floor 200 forms the sound insulating floor 200 by using an anisotropic hollow backing panel 210, and arranging so that the anisotropic direction of the adjacent hollow backing panels 210 crosses at a right angle to each other.
