To provide a ceiling hanger capable of improving sound insulation by reducing propagation of the noise generated on an upper floor to a lower floor ceiling.SOLUTION: A ceiling hanger 1 includes a floor side fixing part 2 fixed to the floor side of an upper floor, a ceiling support part 3 supporting a lower floor ceiling structure, a first vibration isolation part 4 provided in the floor side fixing part and suppressing vibration propagation from the floor side, and a second vibration isolation part 341 provided in the ceiling support part and suppressing vibration propagation to the lower floor ceiling structure. The vibration isolating characteristic of the first vibration isolation part 4 is different from the vibration isolating characteristic of the second vibration isolation part 341.SELECTED DRAWING: Figure 1
【課題】上階で発生した騒音の下階天井への伝播を低減して防音性を向上できる天井吊具を提供する。【解決手段】天井吊具１は、上階の床側に固定される床側固定部２と、下階天井構造を支持する天井支持部３と、上記床側固定部に設けられて上記床側からの振動伝播を抑制する第１防振部４と、上記天井支持部に設けられて上記下階天井構造への振動伝播を抑制する第２防振部３４１と、を備える。上記第１防振部４の防振特性と上記第２防振部３４１の防振特性は相違する。【選択図】図１
