Description of the Related Art Recently, there has been a problem that sound generated when a child jumps or drops an object on the upper floor, or sound generated from a television, a stereo, or the like reaches downstairs and hinders sleep. From the viewpoint of improving the livability, it has been strongly desired to reduce noise from the second floor.

されている。Generally, in order to prevent sound (airborne sound) from a television or a stereo from being transmitted downstairs, a material having a large surface density or a large thickness, that is, a floor material having a large transmission loss of the airborne sound, is used. It is said that it is necessary to use soundproofing or to reduce the number of openings that easily leak sound. On the other hand, in order to prevent sound propagating as vibration sound (solid sound transmission) from being transmitted downstairs due to impact on a structure such as a wall or a floor such as a child jumping or dropping an object, (1) (2) installing a high-density plate material (that is, a sound-insulating material having a high surface density) in the space under the ceiling; and (3) installing a cushioning material (effective for a lightweight impact source). It is necessary to increase the rigidity of the floor structure (effective for a heavy impact source). Various sound-insulating floor materials and floor structures have been proposed to solve such problems.

としてはほとんど使用されていなかった。However, in so-called detached houses such as wooden houses and steel-framed houses, particularly in wooden houses built by small and medium-sized construction shops and carpenters in the area, it has been difficult to impart sufficient sound insulation to the houses. This is because wooden houses and steel-framed houses are lightweight and have low rigidity, so even if high-rigid flooring is used, the effect is not fully exhibited. Because it is rarely built, it took considerable time and effort to implement sound insulation measures including the floor structure, resulting in high costs. On the other hand, a cement-based molded plate is considered to be used as a sound insulating flooring material because of its high surface density and bending rigidity.However, when a low rigidity joist is used or the number of nails used for fixing to the joist is small, If the fixing is insufficient, there is a problem that a sufficient sound insulation effect cannot be obtained. Moreover, it is difficult for small and medium-sized construction firms and carpenters to use cement-based molded boards as flooring materials, because cement-based molded boards generally have poor sawing and nailing properties.

The nailing performance at the time of sticking was also good. On the other hand, the floor panels of Comparative Example 1 and Comparative Example 3 using plywood or particle board as plate materials were easy to manufacture, but had low surface density and insufficient bending rigidity, and thus had little sound insulation effect. Was. Further, the floor panel using the ALC plate as a plate material has a sufficient bending rigidity although the surface density is insufficient, so that a certain degree of sound insulation effect was expected. However, since only a sheet having a width of 606 mm was available, two ALC plates were spliced together when forming a panel, so that sound leaked from the joint and there was not much sound insulation effect.
