CEILING MEMBER AND CEILING STRUCTURE
To provide a ceiling member excellent in soundproofing property, especially in soundproofing property at high frequency, and also excellent in lightweight property.SOLUTION: A ceiling member has: a spandrel 10 having a square main surface 11, side surfaces 13a, 13b erected toward the same surface side of the main surface 11 on opposite sides 12a, 12b of the main surface 11, a first engagement part 14a provided on one side surface 13a, and a second engagement part 14b having a shape engageable with the first engagement part 14a provided on the other side surface 13b; and an elastic member 20 disposed in a recess part 15 formed by the main surface 11 and the side surfaces 13a, 13b. The maximum thickness of the elastic member 20 disposed in the recess part 15 is larger than the depth of the recess part 15, and the elastic member 20 disposed in the recess part 15 has a compression modulus of 1 MPa or less measured in accordance with JIS K 7220: 2006.SELECTED DRAWING: Figure 1
【課題】防音性、特に高周波数での防音性に優れており、かつ、軽量性にも優れた天井部材を提供する。【解決手段】四角形の主面１１を有し、主面１１の対向する辺１２ａ，１２ｂにおいて主面１１の同一面側に向かって側面１３ａ，１３ｂが立設され、一方の側面１３ａには第１係合部１４ａが設けられ、他方の側面１３ｂには第１係合部１４ａと係合可能な形状の第２係合部１４ｂが設けられているスパンドレル１０と、主面１１及び側面１３ａ，１３ｂによって形成される凹部１５に配置された弾性部材２０とを備え、凹部１５に配置された弾性部材２０の最大厚みは、凹部１５の深さより厚く、凹部１５に配置する弾性部材２０は、ＪＩＳ Ｋ７２２０：２００６に準拠して測定した圧縮弾性率が１ＭＰａ以下である。【選択図】図１
