Abstract
A sound-insulating floor structure, which can conspicuously reduce heavy floor impact sounds, is provided. The sound-insulating floor structure includes a floor base and an underfloor member. A plurality of sound-insulating floor members are arranged between the floor base and the underfloor member, and each of the sound-insulating floor members includes a plurality of impact-absorbing members and a support member supporting the impact-absorbing members. The impact-absorbing members are provided at at least one of upper and lower faces of the support member. Each of the sound-insulating floor members is fixed to the floor base or to the underfloor member, thereby supporting the underfloor member.
