摘要： PURPOSE:To reduce the extent of a floor impact noise due to a light weight impact source in a long joist high floor type soundproof floor by installing a buffer layer in space between a bedding floorboard and a finishing floorboard. CONSTITUTION:A sleeper 4 consisting of wood, laminated wood, etc., and a framework being composed of a long joist 5 consisting of wood, laminated wood or the like are set up on a floor slab 1 via vibro-proofing rubber. Next, a bedding floorboard 3 consisting of a veneer board, a particle board or the like is stuck on the framework. In succession, a finishing floorboard 2 consisting of plywood, flooring or the like is stuck onto the bedding floorboard via a buffer layer 8 consisting of a rubber mat, a soft resin mat or the like. In addition, this buffer layer 8 absorbs any possible impact exciting force to be added to the finishing floorboard 2 in space between both upper and lower living rooms. With this constitution, a floor impact noise due to a light weight impact source is thus reducible.

摘要： PURPOSE:To reduce the extent of a floor impact noise due to a light weight impact source in a long joist high floor type soundproof floor by installing a buffer layer, containing an independent bubble sponge chip mat in space between a bedding floorboard and a finishing floorboard. CONSTITUTION:A sleeper 4 consisting of wood, laminated wood or the like and a framework being composed of a long joist 5 consisting of wood, laminated wood or the like are set up on a floor slab 1 via vibro-proofing rubber 6. Next, a bedding floorboard 3 consisting of a veneer board, a particle board or the like is stuck onto the framework. In succession, a finishing floorboard 2 consisting of fancy plywood, flooring or the like is stuck onto the bedding floorboard 3 via a buffer layer 8 containing an independent bubble sponge mat. In addition, this buffer layer 8 absorbs any impact exciting force to be added to the finishing floorboard 2 in both upper and lower living rooms. With this constitution, a floor impact noise due to a light weight impact source is thus reducible.

摘要： PURPOSE:To reduce the extent of a floor impact noise in a long joist high floor type soundproof floor by setting up a block consisting of sound absorbing material dispersively in space between two long joists beneath a floorboard. CONSTITUTION:A sleeper 3 consisting of wood, laminated wood and a framework being composed of a long joist 4 consisting of wood, laminated wood or the like are set up on a floor slab via vibro-proofing rubber 5. Next, a floorboard 2 consisting of a veneer board, a particle board, flooring or the like is stuck onto this framework. At this time, a block 8 consisting of sound absorbing material is dispersively set up in space between two long joists 4 and 4 beneath the floorboard 2. With this constitution, even if an amount of service consumption in the sound absorbing material is little, a floor impact noise is reducible for both light and heavy impact sources almost in the whole frequency area.

摘要： PURPOSE:To reduce the extent of a floor impact noise in a long joist high floor type soundproof floor by installing a clearance between a floorboard and a wall and/or a column in the peripheral edge of a floating floor, and making a flow of underfloor air be free of running. CONSTITUTION:A sleeper 5 consisting of wood, laminated wood or the like and a framework being composed of a long joist 6 consisting of wood, laminated wood, etc., both are set up on a floor slab 3 via vibro-proofing rubber 7. Next, a floorboard 4 consisting of a veneer board, a particle board, flooring or the like is stuck onto this framework. At this time, a proper clearance 11 is installed in space between the floorboard 4 and a wall 1 and/or a column 1 in the peripheral edge of a floating floor, thereby making a flow of underfloor air be free of running via the clearance 11. In this case, floor impact force having acted on the floorboard 4 is transmitted to a building body of the floor slab 3 via an underflooring space 8, but a resonant phenomenon is attenuated as air in this underfloor space 8 is hermetically sealed. With this constitution, a floor impact noise due to a heavy impact source is thus reducible.

摘要： PURPOSE:To reduce harmful effect of vibration and radiant sound by placing a dynamic vibration absorber, composed of an added load and spring stands, to the upper floor side in a space beneath the upper floor supported above a floor slab, and by making the absorber coordinated to the natural frequency of the floor slab. CONSTITUTION:An upper floor 3 is laid above a floor slab 1 through vibration isolating rubber stands 5, joists 4a (for span) and joists 4b (for connection). A dynamic vibration absorber with a rigid added load 7, made from a concrete block or the like, supported by spring stands 8 and further supported by supporting instruments 11, is laid in a space beneath the floor. By such arrangement, adjustment coordinative to the natural frequency of the floor slab can be made and, because of this, radiant sound 10 produced by impulsive shaking force 9 can be reduced. Thereby, a soundproof floor structure that reduces vibration and radiant sound harmful to the residents of the upper and lower stories can be obtained.

摘要： PROBLEM TO BE SOLVED: To form sound-insulating walls as separation walls of acoustical various rooms in structure, in which the sound-insulating walls can correspond to the time of the generation of the change of a site planning, and to ensure a sound field clearer than that in the case where plasterboards are used on surfaces on the insides of the rooms. SOLUTION: The sound-insulating wall is composed of a fixed sound- insulating wall 2 consisting of a precast concrete board arranged between an upper-layer side slab 4 and a lower-layer side slab 5 and a floating sound- insulating wall 3 made up of the precast concrete board forming a space between the floating sound-insulating wall 3 and the fixed sound-insulating wall 2 and being disposed onto the lower-layer side slab 4. A floor board 6 consisting of concrete is laid on the lower-layer side slab 5 under the state, in which the floor board 6 is not brought into contact directly with the lower-layer side slab 5, and the floating sound-insulating wall 3 is arranged onto the floor board 6.

摘要： PURPOSE:To keep sonically good living environment by reducing the noise and vibration generated from a bubble bathtub and to anchor said bathtub to a multiple dwelling house, by arranging the bubble bathtub on a damping stand having a heavy wt. and arranging said damping stand to a base through a damping member. CONSTITUTION:A damping stand 5 has damping effect as the wt. thereof is increased and has effect in an aspect reducing the up-and-down behavior of the upper peripheral part of the bathtub when the loads of water and a person are added. Therefore, a cross-sectional shape increasing the wt. of the stand as heavy as possible by making only the part directly above the arrangement place of vibrationproof rubber is employed and a pan-shaped box 9 made of stainless steel for rust inhibition is filled with concrete 10. The planar shape of the damping stand 5 is determined corresponding to the shape of a bathroom and is not especially restricted and the bathtub 7 is placed on the damping stand 5. The vibration proof rubbers 4 arranged at 6-8 places by calculating a center-of-gravity position on the basis of the shape of the damping stand 5 are made of rubber having high water resistance and said stand 5 is constituted by arranging ones having an almost S-shaped structure in order to reduce the shaking in a horizontal direction to make the spring constants equal in vertical and horizontal directions.
