The acoustic building of the present invention comprises a floor wall, a side wall, a ceiling wall, a frame member provided on the floor wall and spaced apart from the floor wall, and the side wall on the frame member. a laminated floor spaced apart; and a first elastic body spaced from the side wall between the side wall and the frame member, wherein the side wall and the first elastic body is less than the distance between the side wall and the edge of the laminated floor, and the frame member inserts a plate member parallel to the floor wall between the floor wall and the laminated floor. and a second elastic body is provided between the plate member and the floor wall.

FIG. 1 is an external perspective view of an acoustic building 1 of this embodiment. Here, the floor wall 40, the side walls 20, the ceiling wall 70, the external door 52, etc. are illustrated. The entire structure of the acoustic building of this embodiment, including the floor wall 40, the side wall 20 and the ceiling wall 70, is in the shape of a shipping container.

FIG. 2 is a plan view of the acoustic building of this embodiment. In this embodiment, an inner door 51 and an outer door 52 are provided, and the inner door 51 is used as a soundproof door. A panel area 53 is provided inside the outer door 52 . In the panel area 53, for example, an outdoor unit of an air conditioner, a power supply panel, and the like can be provided.

FIG. 3 is a cross-sectional view of the acoustic building of this embodiment, corresponding to the AA cross section of FIG. A mirror 28, a sound absorbing panel 29, or the like may be attached to the inner side of the side wall 20 as necessary. The installation area, material, etc. of the sound absorbing panel 29 are appropriately changed according to the purpose of use. For example, it can be changed according to the type of musical instrument in the musical instrument performance. Also, the floor wall 40 may be made of C-shaped steel or the like.

FIG. 4 is a cross-sectional view showing the sidewall 20 in this embodiment. The side wall 20 in this embodiment is composed of an inner wall 21, an outer wall 22, and a soundproof material 23 provided therebetween. The soundproofing material 23 can further enhance the soundproofing and soundproofing effects.

The inner wall 21 may be made of plywood, for example, and may be made of one layer or multiple layers. Among them, a plurality of layers, that is, a laminate is preferable. In the case of a laminate, the effect of soundproofing and soundproofing can be further enhanced.

For example, an iron plate (for example, a corrugated plate) can be used for the outer wall 22, and the thickness thereof can be appropriately changed as necessary. In this embodiment, the thickness of the iron plate is made larger than that of a general transportation container. As a result, the soundproofing effect and the soundproofing effect can be further enhanced.

Although not shown, the top wall 70 preferably has an inner wall and an outer wall like the side walls 20, and the inner wall of the top wall 70 is preferably a laminate. Moreover, it is preferable to provide a soundproof material between the inner wall and the outer wall.

In this embodiment, the entire structure including the floor wall 40, the side walls 20, and the ceiling wall 70 is in the shape of a container for transportation, and the shape of the container for transportation facilitates transportation. For example, by having the first hole 61 (forklift claw hole) and the second hole 62 (lifting hole), the acoustic structure can be moved more easily.

FIG. 5 is a plan view showing the acoustic building according to the present embodiment, and is a diagram showing an example of the arrangement of the steel frame, the first elastic bodies, and the second elastic bodies. In this embodiment, a steel frame 10 is used as a frame member and has a lattice shape.

A plurality of first elastic bodies 11 are provided at intervals, and ten in this embodiment. The number, position, and spacing of the first elastic bodies 11 are not limited to this, and can be changed as appropriate.

FIG. 6 is a schematic cross-sectional view of the essential part showing this embodiment, and corresponds to the BB cross section of FIG. As illustrated, in this embodiment, a first elastic body 11 is provided between the side wall 20 and the steel frame 10, and the distance between the side wall 20 and the first elastic body 11 (( b)) is smaller than the distance between the side wall 20 and the edge of the laminate floor 30 ((a) in the figure).

As a result, even when the laminated floor 30 vibrates in the lateral direction (direction parallel to the floor wall 40), the first elastic bodies 11 come into contact with the side walls 20 before the laminated floor 30 contacts the side walls 20, so that the laminated floor 30 Contact with the side wall 20 can be prevented. Therefore, it is possible to suppress deterioration due to lateral vibration of the laminated floor when the acoustic building of this embodiment is used or transported.

In addition, by using the first elastic body 11, it is possible to adjust the width of the lateral vibration of the laminated floor 30, thereby suppressing excessive vibration. On the other hand, if the width of the laminated floor 30 swaying in the horizontal direction is large, the laminated floor 30 deteriorates, and the second elastic body (described later) provided between the laminated floor 30 and the bottom wall 40 tends to deteriorate. put away.

The distance ((b) in the drawing) between the side wall 20 and the first elastic body 11 can be appropriately changed depending on the mass of the laminated floor 30, the material of the first elastic body 11, and the like. For example, in this embodiment, the distance between the side wall 20 and the first elastic body 11 is 5 mm. Also, the distance between the side wall 20 and the edge of the laminated floor 30 ((a) in the figure) is 20 mm.

The first elastic body 11 of this embodiment is adhered to the steel frame 10 and provided apart from the floor wall 40 . Friction between the first elastic body 11 and the floor wall 40 can be suppressed by separating the first elastic body 11 from the floor wall 40 . Also, although the first elastic body 11 in this embodiment is provided apart from the laminated floor 30 , it is not limited to this and may be in contact with the laminated floor 30 .

In the example shown in FIG. 6, the steel frame 10 is provided apart from the floor wall 40, because the second elastic body 12, which will be described later, is provided. Since the steel frame 10 is separated from the floor wall 40 , it is possible to further prevent vibrations from the laminated floor 30 from being transmitted to the side walls 20 . However, the arrangement of the steel frame 10 is not limited to this, and may be in contact with the floor wall 40 .

When moving the acoustic structure, a fixing member such as an L-shaped clamp may be used to fix the laminated floor 30 . In this case, deterioration during movement can be further prevented.

On the other hand, for example, Patent Document 1 discloses a configuration in which an elastic body is provided between the bottom wall and the ground (Fig. 9 of Patent Document 1). , it is difficult to move the container from the place where it is installed. In addition, in the case of the structure shown in FIG. 4 of Patent Document 1, even if there is a hole for a forklift, there is a concern that the claws of the forklift may come into contact with the raised floor, which will affect the soundproofing effect and vibrationproofing effect. It is difficult to move as one because it gives.

FIG. 7 is a schematic cross-sectional view of the essential part showing the present embodiment, and corresponds to the CC cross section of FIG. As illustrated, the steel frames 10 are spaced apart on the floor wall 40 and the laminated floor 30 is provided on the steel frames 40 . The laminated floor 30 is provided apart from the side wall 20 , and the separation of the laminated floor 30 from the side wall 20 can prevent the vibration of the laminated floor 30 from propagating to the side wall 20 .

The floor wall 40 in this embodiment is not particularly limited, and can be changed as appropriate. For example, a combination of steel frame and urethane can be used. Further, as shown in FIG. 3, the floor wall 40 may include C-shaped steel or the like.

FIG. 8 is an enlarged schematic diagram of a main part in FIG. As illustrated, a plate member (iron plate 13) parallel to the floor wall 40 is attached to the steel frame 10 by, for example, adhesion, and the second elastic body 12 is provided between the iron plate 13 and the floor wall 40. . Also, the iron plate 13 and the second elastic body 12 are fixed by a screw construction method using screws 14 .

In this embodiment, the laminated floor 30 is not directly grounded, but has a floating floor structure provided on the second elastic body 12 . Thereby, resonance of internal sound can be prevented. On the other hand, since the first elastic body 11 is provided, the effect of the second elastic body 12 can be exhibited more effectively, and deterioration of the second elastic body 12 can be prevented.

In this embodiment, the steel frame 10 is provided apart from the floor wall 40 . It is preferably spaced even when under load. Thereby, the above effects are more exhibited. In addition, in this embodiment, the distance between the steel frame 10 and the floor wall 40 is 10 mm, for example.
In order to keep the steel frame 10 and the floor wall 40 apart even when a load is applied, the thickness, type, number and arrangement of the second elastic bodies 12 may be appropriately adjusted.

In addition, by adopting a configuration using plate members (iron plates 13), the distance between the laminated floor 30 and the floor wall 40 can be suppressed to about the height of the steel frame 10, thereby suppressing the height of the laminated floor 30. can be done. On the other hand, the second elastic body 12 may be arranged above or below the steel frame 10 without using the iron plate 13, but it should be noted that the height of the laminated floor 30 will be increased.

By having the second elastic body 12, it is possible to prevent the vibration of the laminated floor 30 from propagating to the side wall 20 via the floor wall 40, and prevent sound leakage caused by the propagation of sound and vibration to the side wall 20. can be prevented.

The position and the number of the second elastic bodies 12 are set as shown in FIG. As shown in FIG. 5, the uneven arrangement allows the load applied to the laminated floor 30 and the steel frame 10 to be distributed more evenly. By arranging the second elastic bodies 12 at different distances instead of at a constant distance, it is possible to absorb not only the sound of a specific frequency but also the sound of a plurality of frequencies.

The second elastic body 12 is not particularly limited, and can be changed as appropriate. For example, commercially available anti-vibration rubber can be used. Also, the size, elasticity, etc. can be changed as appropriate. Furthermore, the arrangement positions and the number of the second elastic bodies 12 are not limited to those described above, and can be changed as appropriate.

In this embodiment, a soundproof material 43 is provided between the laminated floor 30 and the floor wall 40 . This prevents the sound from being reflected and amplified between the laminated floor 30 and the floor wall 40, thereby enhancing the soundproofing effect.

As described above, the distance between the side wall 20 and the first elastic body 11 ((b) in the figure) is smaller than the distance between the side wall 20 and the laminated floor 30 ((a) in the figure). ing. On the other hand, when the distance between the side wall 20 and the laminated floor 30 ((b) in the drawing) is less than or equal to the distance between the side wall 20 and the first elastic body 11 ((a) in the drawing), the laminated floor 30 vibrates in the lateral direction, it contacts and collides with the side wall 20.例文帳に追加When the laminated floor 30 contacts or collides with the side wall 20, the vibration of the laminated floor 30 is propagated to the side wall 20, or the lateral vibration of the laminated floor 30 applies a load to the second elastic body 12, causing the second elastic body 12 to move. Problems such as accelerated deterioration of the body 12 arise.

9-11 are plan views showing the layers of the laminated floor.
The configuration of the laminated floor is not particularly limited, and can be changed as appropriate. The laminated floor of this embodiment is composed of a first wooden board 31, an iron board 32 and a second wooden board 33 in order from the floor wall. Plywood, for example, can be used as the first wooden board 31 and the first wooden board 33 . In addition to the above, a sound insulation sheet or the like may be provided.

By adopting a laminated structure as in the present embodiment, it is possible to enhance the soundproofing effect while having high rigidity. By using a laminated structure, it is possible to prevent not only sounds of specific frequencies but also sounds of various frequencies.

9 to 11 are plan views of the first wooden board 31, the iron plate 32 and the second wooden board 33, respectively. In addition, the steel frame 10 is shown by the broken line.
As shown in the figure, the laminated floor 30 of the present embodiment is formed by laminating layers composed of a plurality of divided members, and the boundaries between the plurality of members are inconsistent between the layers.

By forming each layer from a plurality of divided members, transmission of specific frequencies can be prevented. When each layer is made of one member, a specific frequency is likely to be transmitted, and transmitted through the laminated floor 30 to propagate to the floor wall 40 and the side wall 20, and sound leakage is likely to occur.

The inconsistency of the boundaries between the members between the layers effectively prevents different frequency sounds generated inside the acoustic building. When the boundaries of the layers coincide with each other, specific frequencies are more likely to pass through the laminated floor 30 and propagate to the floor walls 40 and side walls 20, resulting in more sound leakage.

Note that "the boundaries between a plurality of members do not match between layers" means that the boundaries between layers do not all match, and a part of the boundaries may match. Moreover, when the boundary is grasped as a line, the line may intersect between the layers.

Also, in this embodiment, as illustrated, the boundaries between the members in each layer are patterned. The term "patterned" refers to, for example, those in which all members are regularly arranged as shown in FIGS. and partly arranged differently.

In addition, the area of the plurality of members in each layer can be changed as appropriate, and all the members may have the same area or may have different areas. Among them, it is preferable to have at least one member having a different area. In this case, since the sound of the frequency corresponding to the area of the member can be absorbed, the sound of more frequencies can be absorbed. Moreover, the resonance caused by the same area can be further suppressed.

In the laminated floor of this embodiment, a first wooden board 31, an iron plate 32 and a second wooden board 33 are laminated in this order. By adopting such a configuration, it is possible to suppress problems such as the formation of gaps due to contraction of the iron plate, and it is possible to further prevent sound leakage.

Although the number of layers can be changed as necessary, it is preferable to use three layers as in the present embodiment in consideration of the thickness of each layer, the mass of the layered floor 30, the effect of soundproofing, and the like. By setting an appropriate number of layers, there is an advantage that even if the layered floor 30 vibrates, the entire layer is less likely to vibrate.

In addition, if the number of layers is appropriate, the rigidity of the laminated floor 30 can be increased while suppressing the mass of the laminated floor 30 from becoming too large.

The thickness of each layer in the laminated floor 30 can be changed as appropriate, but the thickness of each layer is preferably different. In this case, propagation of sound of a specific frequency can be suppressed.

The acoustic building of this embodiment can be used for various purposes. Examples include musical instrument performance studios, residences, offices, game arcades, sports gyms, and restaurants. It is also possible to install solar panels and supply power by photovoltaic power generation.
The installation location of the acoustic building of this embodiment can be changed, and it may be installed outdoors or indoors. Since it is movable, it has the advantage of being able to change the place of use and facilitate second-hand sales.
