Abstract

PROBLEM TO BE SOLVED: To reduce propagation of an impact sound on the floor face of upper floors to under floors by disposing a porous plate on the lower side of a floor joist, arranging a plate material on the upper side of the floor joist to form a hollow part, and providing a sound absorbing material on the hollow part. SOLUTION: Sets of two floor joists 3 are disposed at required intervals, and a wooden porous plate 4 is fixed on the lower side of the floor joist 3 so that a part of the floor joist is exposed. A sound absorbing material 5 composed of rock fiber of required thickness is fitted between the upper face floor joists 3 of the porous plate 4, and the plate material 6 of a wooden plywood is fixed on the upper side of the floor joist 3 to mold a floor panel 1. Next, the floor panel 1 is laid on an upper story floor beam 2, and a floor finish material 7 composed of a decorative plywood is stuck on the plate material 6 of the floor panel 1. A ceiling material 11 is hung on the lower side of the floor beam 2 by a hanging member 10 mounting a vibration-proof hanging timber 9 from a hanging receiving member 8, and a sound absorbing material 12 composed of rock fiber is disposed on the upper face of the ceiling material 11. Thus, impact sound on the floor face is reduced to eliminate discomfort feeling in the lower floors for the impact sound.

By the way, in the above-mentioned prior art, since there is a large space between the upper floor and the lower floor ceiling, the acoustic reflection area due to the impact sound on the upper floor is large, and the impact sound is reduced as described above. It is transmitted to the lower floor as air propagation in the space, and is reduced to some extent by the ceiling assembly (plaster board, ceiling finishing material), but the generation of unpleasant noise cannot be suppressed. In addition, the impact vibration of the upper floor is caused by the lower floor finishing material 1
There is a problem that the sound propagates to the lower floor and generates an unpleasant sound. Moreover, in the prior art, the sectional rigidity of the floor set itself is small, and no measures against heavy floor impact noise are taken.
