Description of the Related Art In a building, noise that is a problem between floors and between adjacent rooms is a sound that is generated when a person starts speaking, walking, walking, or playing a musical instrument such as a piano. , And various other things. In particular, in apartment houses such as condominiums, in recent years, the number of flooring-type rooms that use wood-based flooring materials has increased, and with the spread of audio equipment, the noise generated from daily life has become more and more serious. . Conventionally, as a sound insulation means for these noises, an increase in the mass of concrete or the like,
In other words, in addition to increasing the thickness of the slab and the doorway wall, we adopted materials with high sound insulation performance for the floor material and attached sound insulation sheets to the slab and the doorway wall.

っており、有効な解決策が望まれていた。However, in the sound insulation means for increasing the thickness of the slab and the door wall as described above, it is usually necessary to hit about 13 cm of concrete to hit about 20 cm at a place with sufficient strength. As described above, hitting concrete with a strength higher than necessary for sound insulation has many problems such as an increase in the weight of the building, an increase in the construction cost and a longer construction period. . In addition, it is said that a method such as attaching a sound insulation sheet to a slab or a doorway wall or using a floor material with high sound insulation performance is very time-consuming when constructing, and the cost per unit area is said to be high. Have challenges. Therefore, there are still many buildings that do not have satisfactory sound insulation performance, which is a big social problem, and an effective solution has been desired.

転することができる。Since the member having the sound absorbing property is arranged by the spraying means, it can be completely applied to various shapes of the building, and the outer surfaces such as the floor slab and the doorway wall are shielded from the atmosphere. It That is, the vibration energy generated in the floor slab and the door boundary wall is absorbed by the buffering effect of the air bubbles contained in the sound absorbing member, and is prevented from propagating to the outside of the foamable resin layer. Then, the vibration energy is completely absorbed by the synthetic resin layers having different sound absorbing characteristics, which are laminated and coated on the foamable resin layer. Further, the sound insulation is made more complete by the raising material arranged on the surface of the sound absorbing layer, and the noise generated in the adjacent room is not transmitted to the living room. Similarly, the noise generated in the living room is not transmitted to the adjacent room. Further, since these sound absorbing layers also have a function as a heat insulating material, the air conditioner and the like can be efficiently operated.

According to this, the outer surface 3a of a floor slab 3 and the outer surface 4a of a doorway wall 4 have sound absorbing properties. The sound absorbing layer 5 of the member is provided, and the wall finishing material 7, the floor finishing material 8 and the ceiling finishing material 9 are arranged on the surface 5c of the sound absorbing layer. In the present embodiment, the sound absorbing layer 5 is formed into a plurality of layers, for example, two layers as shown in FIGS. 2 and 3, and the foamable resin is applied to the outer surface 3a of the floor slab 3 by a spraying means such as a spray. A layer 5a is coated, and a high-density and heavy-mass synthetic resin layer 5b made of a soft resin is coated on the layer 5a by the spraying means. Also, as shown in FIG. 3, the outer surface 4 of the doorway wall 4
Also in a, the foamable resin layer 5a and the synthetic resin layer 5b are formed in two layers by the same means as described above.

aに吹き付けコーティングすることもできる。The foamable resin layer 5a is, for example, 3 to 5 mm.
The bubbles 6 for obtaining a buffering effect are obtained by spraying so as to have a thickness and using urethane foam as the material. The synthetic resin layer 5b to be overlaid is sprayed so as to have a thickness of about 2 mm, and synthetic rubber or soft resin such as vinyl chloride is used as its material. However, the materials and dimensions shown here are examples, and other sound absorbing members may be used for the outer surface 3 a of the floor slab 3 and the outer surface 4 of the doorway wall 4.
It is also possible to spray-coat a.

When spraying the layer 5a, it is necessary to remove stains or the like on the outer surfaces 3a and 4a in advance.

According to this embodiment, since the two sound absorbing layers 5 are formed by the spraying means, the sound absorbing layer 5 can be completely applied to a complicated portion in the living room 2. In other words, the living room 2 (adjacent room 1 formed by being partitioned by the floor slab 3 and the doorway wall 4)
0-13) can be completely covered with the expandable resin layer 5a and the synthetic resin layer 5b, which are shielded from the atmosphere.

This vibration energy is first blocked by the foamable resin layer 5a, and is further absorbed by the buffering action of the bubbles 6 contained in the foamable resin layer 5a to prevent it from propagating to the outside of the foamable resin layer 5a. I'm out. Next, a synthetic resin layer 5b having different sound absorbing characteristics, which is coated on the foamable resin layer 5a in a different manner.
The vibration energy is completely absorbed by. Then, the wall finishing material 7, the floor finishing material 8 and the ceiling finishing material 9 arranged on the surface 5c of the sound absorbing layer 5 provide more complete sound insulation, and the noise generated in the adjacent rooms 10 to 13 becomes
Will not be transmitted to. Similarly, noise generated in the living room 2 is not transmitted to the adjacent rooms 10 to 13. Further, since the sound absorbing layer 5 can also serve as a heat insulating material by the action of the bubbles 6 contained in the foamable resin layer 5a, it can contribute to energy saving such as efficient operation of an air conditioner and the like.

ルギにも寄与することができるものである。As is apparent from the above description, according to the present invention, the following excellent effects can be obtained. In other words, since a member having a sound absorbing property is applied by spraying to completely cover the noise transmission path, it is possible to obtain a remarkably dampening characteristic as never before and to reduce noise between adjacent dwelling units such as condominiums. Complete sound insulation can be achieved. Moreover, since such a spraying method can be carried out in the same manner as the painting work, it can be easily and safely carried out in a short period of time at low cost. In addition, since the sound absorbing layer formed by the method of spraying is a lightweight member such as foamable resin or synthetic resin, it does not apply an extra load to the building, so that concrete pouring can be kept to the necessary minimum. In addition to the above, the heat insulating function of the sound absorbing layer can contribute to energy saving such as efficient operation of the air conditioner and the like.
