CEILING VIBRATION ISOLATION MATERIAL AND CEILING VIBRATION ISOLATION STRUCTURE
To provide a ceiling vibration isolation material and a ceiling vibration isolation structure having a vibration isolation property against floor impact sound in a wide range of frequency band without depending on weight.SOLUTION: A ceiling vibration isolation material 10 laid over opposing ceiling backing materials 20 in the ceiling backing materials 20 supporting a ceiling surface material 40 comprises: a hat material 3 of a hat shape in a front view in which left and right L-shaped locking pieces 1 locked to the ceiling backing materials 20 and a bottom piece 2 connecting the left and right locking pieces 1 are integrated; and a vibration isolators 5 which is attached to each of the right and left sides of the bottom surface 2a of the bottom piece 2 and is brought into contact with the ceiling surface material 40 in a compressed state within a compression ratio of 10% to 20%.SELECTED DRAWING: Figure 1
【課題】重量に依存することなく、広範囲の周波数帯域の床衝撃音に対する防振性を有する天井防振材及び天井防振構造を提供すること。【解決手段】天井面材４０を支持する天井下地材２０において、対向する天井下地材２０に架け渡される天井防振材１０であって、天井下地材２０に係止される左右のＬ型の係止片１と、左右の係止片１を繋ぐ底片２と、が一体とされている、正面視ハット型のハット材３と、底片２の底面２ａの左右二箇所に取り付けられていて、圧縮率１０％乃至２０％の範囲で圧縮された状態で天井面材４０に当接される防振材５と、を有する。【選択図】図１
