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. |
