とを特徴とする。[Structure of the Invention] Means for Solving the Problems The method for preventing sound insulation defects in a finished wall directly attached to a board of the present invention is to apply a kneading bond to a wall base surface such as a concrete skeleton in a dango-like manner at appropriate intervals, A wall board is pasted with a felt-like cushioning material made of a fiber system such as glass fiber or rock wool fiber between and, and an air layer of 35 to 60 mm is provided between the wall base surface and the wall board. It is characterized by being formed.

The wall board 3 has a thickness of 12 mm or 15 mm, for example, and the cushioning material 4 described above is used. Is a felt-like material made of glass fiber or rock wool fiber, for example, and has a thickness of 1 to several mm.
Are preferred.

成する。As shown in FIG. 4, the wall board 3 with the cushioning material 4 as described above is adhered by pressure contact with the cushioning material 4 being sandwiched between the bond 2 previously applied in a dango shape on the concrete skeleton 1. To do. Here, the interval between the dango-shaped bonds 2 is, for example, 450 mm, and the height of the mountain is increased to make the cushioning material 4
An air layer 5 (see FIG. 5) having a thickness of 35 to 60 mm is formed.

くなったことによる。FIG. 6 is a comparison of the sound insulation performance between the finished wall directly attached to the board by the sound insulation loss prevention method of the present invention and the conventional one. As is clear from this figure, the sound insulation performance is improved over all frequencies. It can be seen that there is a great improvement, especially near 250 to 500 Hz and 4,000 Hz. This is bond 2 and wall board 3
Since the cushioning material 4 is sandwiched between and, it becomes difficult for the vibration of the concrete skeleton 1 to be transmitted to the wall board 3, so that the sound insulation loss in the high frequency range near the coincidence frequency of the wall board 3 is prevented. Further, since the wall board 3 is attached in a state of being floated by the cushioning material 4, resonance in the middle and low frequency band of the wall board 3 having the bond 2 as a support point is eliminated.

ランスのとれた遮音性能とすることが出来る。Also, by increasing the height of the bond 2, the air layer 5 is made about 20 mm thicker than the conventional thickness (20 to 25 mm) to a thickness of about 35 to 40 mm, and the cushioning material 4 is used as described above. By sandwiching. The resonance frequency of the air layer 5 can be lowered from the conventional 250 Hz to 100 Hz, and the sound insulation performance can be balanced as a whole.

る。[Advantages of the Invention] (1) Since the felt-like cushioning material made of a fiber system such as glass fiber or rock wool fiber is adopted, vibration transmission transmitted from the bond to the wall board is reduced, and sound insulation due to resonance of the surface of the wall board is achieved. It is possible to prevent the deterioration of the function.
