Description of the Related Art Conventionally, the floor of the first floor or the upper floor of a pre-hap building using a wooden house or lightweight steel, etc., has a joist member on the upper floor of the first floor. In the floor part, joist members are arranged on the beam members, a heat insulating material is usually arranged between the joist members, and a floor board material is stretched on the joist member on the upper layer with a moisture-proof layer interposed between them. It is widely known to place finishing flooring. Then, the joist member and the haul or beam member have been pinned with an angle metal fitting or a vault nut and positioned.

きる。In the vibration isolating and sound insulating device of the floor according to the present invention, since the joist member connected to the horizontal member such as the big pull or beam of the building is elastically held, the vibration between the rigid bodies can be alleviated and the joist. The porous material of the crushed particles of the ALC panels placed between the materials makes the sound insulation effect more efficient, and the sound absorbing plywood floor and non-combustibility are provided on the space part and the joist material provided on the crushed particles of the ALC panel. Since a finishing floor material is stretched after forming a composite floor part in which boards and lightweight cellular concrete panels are laminated, an AL that is interposed between the joists of the floor parts of the upper floor and the lower floor.
The crushed particles of the C panel and the above-mentioned composite floor portion laminated on the C panel can alleviate the vibration propagating to the floor portion, absorb the vibration sound waves and damp them, thereby providing vibration damping and sound insulation effects.

It turned out to be excellent. This has not been fully elucidated scientifically, but when sound waves enter the porous channels of the crushed particles, the porosity of the crushed particles of large size and the porosity of the crushed particles of small size are obtained. There is a difference in the wave-dissipating effect between the channel and the channel depending on the wavelength of the sound wave. Therefore, the sound wave that is difficult to be attenuated and attenuated in the large-grained porous channel is attenuated in the small-grained porous channel, On the contrary, it is recognized that the sound waves with small particle size and difficult to be wave-absorbed are wave-damped and attenuated by the porous channels of the large-sized crushed particles.
