において大きい。[Problems to be Solved by the Invention] In the above-mentioned conventional building, there is a problem in that weight impact noise caused by children jumping on the upper floor is transmitted to the lower floor. According to the findings of the present inventors, this weight impact sound is caused by the sound being supported by the lower floor ceiling structure when the load acting on the floor surface of the upper floor propagates to the lower floor ceiling structure via the upper floor structure. This occurs due to the bending vibration of the ceiling support material and ceiling surface material, and is particularly large in the mid-to-high range.

。In addition, as a conventional soundproof structure for buildings, for example,
As described in Japanese Patent No. 17884, there is a system that elastically supports the lower floor ceiling by shearing deformation of an elastic body. However, in this soundproof structure, it is necessary to arrange an elastic support member made of vibration-proof rubber or the like in the ceiling, and to attach the lower floor ceiling to the elastic support member so as to suspend it, which makes the ceiling structure complicated.

量衝撃音発生を抑制する。[Function] Since the stiffener is arranged to intersect with the ceiling support material, it is possible to improve the planar rigidity of the ceiling and effectively suppress bending vibration of the ceiling support material. Therefore, a weight impact load such as a child jumping on the upper floor propagates to the ceiling support material through the upper floor structure and the lower floor ceiling structure, causing bending vibration in the ceiling support material. At this time, this bending vibration is effectively suppressed by the presence of the stiffener. In other words, the stiffener suppresses the generation of vibrations in the ceiling support material, and as a result also suppresses the generation of bending vibrations in the ceiling surface material, and prevents the generation of heavy impact noise, especially in medium and high frequencies, due to the vibration of the ceiling support material and ceiling surface material. suppress.
なお、補剛材は天井面材の裏面領域に設けられるもので
あるから、天井表面の美観を損ねたり、下階天井高さを
低くすることもなく１重量衝撃音の発生を抑制できる。In addition, since the stiffener is provided in the back surface area of the ceiling surface material, the generation of single-weight impact noise can be suppressed without spoiling the aesthetic appearance of the ceiling surface or lowering the height of the ceiling of the lower floor.
すなわち、本発明によれば、補剛材を前述の如く設ける
