Sound-insulating floor structures, sound-insulating floor members and method for constructing said sound-insulating floor structures
First Claim
1. A sound-insulating floor structure comprising a floor base, a plurality of sound-insulating floor members arranged on the floor base, and an underfloor member placed on the sound-insulating floor members, each of said sound-insulating floor members comprising a plurality of impact-absorbing members and a support member supporting said impact-absorbing members, said impact-absorbing members being provided on lower faces and optionally on upper faces of the support member, said impact-absorbing members on the lower faces of the support member extending to the floor base, each of said sound-insulating floor members being fixed to the floor base or the underfloor member to support the underfloor member, and each of the impact-absorbing members possesses at least one spring characteristic selected from a linear spring, a degressive spring, progressive spring and a stationary load spring, and at least one impact-absorbing member has a spring characteristic different from that of another impact-absorbing member.

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.

- 1. A sound-insulating floor structure comprising a floor base, a plurality of sound-insulating floor members arranged on the floor base, and an underfloor member placed on the sound-insulating floor members, each of said sound-insulating floor members comprising a plurality of impact-absorbing members and a support member supporting said impact-absorbing members, said impact-absorbing members being provided on lower faces and optionally on upper faces of the support member, said impact-absorbing members on the lower faces of the support member extending to the floor base, each of said sound-insulating floor members being fixed to the floor base or the underfloor member to support the underfloor member, and each of the impact-absorbing members possesses at least one spring characteristic selected from a linear spring, a degressive spring, progressive spring and a stationary load spring, and at least one impact-absorbing member has a spring characteristic different from that of another impact-absorbing member.
- 3. A sound-insulating floor member to be provided between a floor base and an underfloor member above said floor base, said sound-insulating floor member comprising a plurality of impact-absorbing members and a support member supporting said impact-absorbing members, said impact-absorbing members being provided on lower faces and optionally on upper faces of the support member, wherein when a plurality of said sound-insulating floor members are arranged between the floor base and the underfloor member, said impact-absorbing members on the lower faces of the support member extending to the floor base and each of said sound-insulating floor member being fixed to the floor base or the underfloor member to support the underfloor member, and each of the impact-absorbing members possesses at least one spring characteristic selected from a linear spring, a degressive spring, progressive spring and a stationary load spring, and at least one impact-absorbing member has a spring characteristic different from that of another impact-absorbing member.

23. A method for constructing a sound-insulating floor structure comprising a floor base, a plurality of sound-insulating floor members on said floor base, and an underfloor member on the sound-insulating floor members, said method comprising the steps of preparing a plurality of impact-absorbing members and support members for supporting said impact-absorbing members, forming each of the sound-insulating floor members by providing the impact-absorbing members on lower faces and optionally on upper faces of the support member, arranging the sound-insulating floor members between the floor base and the underfloor member such that the impact-absorbing members on the lower faces of the support member extend to the floor base, fixing each of the sound-insulating floor members to the floor base or the underfloor member, and thereby supporting the underfloor member with the sound-insulating floor members.
