大きくなるという問題があった。However, when a single metal plate is used as a ceiling material, since the surface is hard, it reflects sound and is hardly absorbed (NRC = 0.
1). Therefore, an opening for absorbing sound is provided by punching or the like, but in this case, there is a problem that the appearance of the metal surface is impaired by the opening, which makes the appearance unsightly and the design limit becomes large.

Therefore, the metal foil 2 on the surface vibrates due to sound and vibrates. Is absorbed by the elastic fiber layer 3 inside, so that sound is not reflected and it is not necessary to provide a sound absorbing opening on the metal surface. Therefore, the surface makeup can be freely applied while leaving the appearance of the metal surface good.

いる。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In this embodiment, the ceiling material 1 is illustrated as being bridged over the flange portions 5 and 5 of the left and right ceiling bars 4 and 4. The surface of the ceiling material 1 is covered with stainless steel foil (metal foil) 2 that is hard and has a decorative makeup. The stainless steel foil 2 is set to have a thickness of, for example, about 50 μm so that the film is easily vibrated.

いる。On the other hand, inside the ceiling material 1, a rock wool board layer (fiber layer) 3 is packed. The rock wool board layer 3 is lightweight, has elasticity, and can absorb the vibration of the stainless steel foil 2.
Rock wool board of 00 Kg / m 3 is used. Here, when the rock wool board is a wet rock wool board using starch as an adhesive, the density is high (300 Kg / m 3 or more), and the elasticity is also low, so it is difficult to obtain sound absorption characteristics. Will be things. From this, in the present embodiment, for example, rock wool is blown away in the air, an adhesive (phenolic resin or the like) is sprayed, and the net is blown to be molded to have elasticity capable of absorbing the vibration of the stainless steel foil 2. The dry rock wool board is used.

作製することができる。Therefore, when the stainless steel foil 2 on the surface vibrates due to sound, this vibration is absorbed by the elastic rock wool board layer 3, which is different from the conventional metal veneer. The reflection can be sufficiently prevented. Therefore, since there is no opening for sound absorption by punching on the metal surface and there is no restriction on the design, it has a sound absorbing property while leaving the appearance of the metal surface or in the state where the surface makeup can be freely applied. The ceiling material 1 can be manufactured.

という効果がある。As described above, according to the present invention, since the surface is covered with the hard metal foil and the fiber layer having elasticity is provided inside, the film vibration of the metal foil on the surface and the sound absorption of the fiber layer inside are absorbed. As a result, it is possible to prevent the reflection of sound, and as a result, there is an effect that the ceiling material can have sound absorbing characteristics without impairing the appearance of the metal surface.
