FIG.

The following describes embodiments of the present invention with reference to the drawings. The various features shown in the following embodiments can be combined with each other.

1. Configuration In the first section, the configuration of this embodiment will be described.

1-1. Soundproofing structure 100
FIG. 1 is a structural diagram showing a soundproof structure 100.

The soundproofing structure 100 comprises a structure body 200, an anti-vibration hanging bracket (second anti-vibration material) 210, a ceiling 300, a wall 400, an anti-vibration rubber (first anti-vibration material) 500, a floor 600, and a constant ventilation duct 700. These components will be described below.

In addition, the soundproofing structure 100 does not have a frame structure. Therefore, the soundproofing structure 100 can be made compact by the amount of space that would be occupied by a frame structure, which allows the floor height of the building to be reduced.

1-2. Body 200
The skeleton 200 functions as a framework that structurally supports the entire building. The skeleton 200 includes, for example, columns, beams, walls, and slabs. The skeleton 200 supports a ceiling 300 and a floor 600. In this embodiment, the frame 200 supports the ceiling 300 via the vibration-proof hanging brackets 210. The frame 200 also supports the floor 600 via the vibration-proof rubber 500. Therefore, the frame 200 supports the ceiling 300. and below the floor 600. The skeleton 200 may be made of, for example, concrete.

1-3. Anti-vibration hanging bracket 210
The vibration-proof hanging fitting 210 is configured to be capable of absorbing shock by deforming due to shock applied to the ceiling 300. The vibration-proof hanging fitting 210 includes vibration-proof rubber (not shown). That is, when vibration (shock) caused by sound occurs in the ceiling 300, the vibration-proof hanging fitting 210 is configured so that the vibration-proof rubber deforms due to the vibration, thereby absorbing the vibration. The vibration-proof hanging fitting 210 is disposed between the frame 200 and the ceiling 300.

1-4. Ceiling 300
FIG. 2 is a diagram showing the configuration of the ceiling 300.

The ceiling 300 is disposed below the structure 200 and is suspended from the structure 200. That is, the ceiling 300 is connected to vibration-proof hanging brackets 210 connected to the structure 200, and is formed as a double ceiling. Since the ceiling 300 is formed as a double ceiling, a space is created between the structure 200 and the ceiling 300, and this space can be used as a piping space for electricity, water pipes, etc. In this embodiment, the space between the structure 200 and the ceiling 300 is used as an installation space for a constant ventilation duct 700.

The ceiling 300 is layered in the order of reinforced gypsum board 310, soundproofing sheet 320, and hard gypsum board 330 from the building structure 200 side to the floor 600 side, and may further be layered with rock wool sound absorbing board 340 or cloth 350. By layering these materials, the ceiling 300 has the effect of attenuating sound 810 propagating upward from within the soundproof structure 100. By layering the materials in the above order, the ceiling 300 has the effect of efficiently attenuating sound 810 propagating upward from within the soundproof structure 100.

1-5. Wall 400
FIG. 3 is a diagram showing the configuration of the wall 400. As shown in FIG.

The wall 400 is provided vertically between the ceiling 300 and the floor 600. The wall 400 is supported by the ceiling 300 and the floor 600. In other words, the wall 400 is separated from the building structure 200 and has a ceiling-front and floor-front configuration. Airtight sound-proof caulking may be applied between the wall 400 and the ceiling 300, and between the wall 400 and the floor 600.

The wall 400 may be layered in the following order from the outside to the inside of the room: steel base material 405, reinforced gypsum board 410, soundproofing sheet 420, hard gypsum board 430, and wallpaper 440. By layering these materials, the wall 400 has the effect of attenuating sound 810 propagated horizontally from within the soundproof structure 100. By layering the materials in the above order, the wall 400 has the effect of efficiently attenuating sound 810 propagated horizontally from within the soundproof structure 100.

1-6. Anti-vibration rubber 500
The anti-vibration rubber 500 is configured to be capable of deforming and absorbing an impact applied to the floor 600. The anti-vibration rubber 500 is disposed between the building frame 200 and the floor 600. The anti-vibration rubber 500 is connected to both the building frame 200 and the floor 600. The anti-vibration rubber 500 may be made of, for example, natural rubber. The anti-vibration rubber 500 has, for example, a cylindrical shape.

1-7. Floor 600
FIG. 4 is a diagram showing the configuration of the floor 600.

The floor 600 is a dry floating floor. In other words, a space is provided between the structure 200 and the floor 600, which prevents sound from being transmitted directly to the structure 200. The floor 600 is placed on top of the anti-vibration rubber 500. When an impact is applied to the floor 600, the anti-vibration rubber 500 compresses and deforms, causing the floor 600 to sink slightly, so the wall 400 and the floor 600 are placed at a predetermined distance from each other.

The floor 600 is constructed by stacking multiple soundproofing plate-shaped members in addition to multiple flooring materials. The multiple flooring materials are configured to improve the construction accuracy of the floor 600. The multiple soundproofing plate-shaped members are configured to improve the soundproofing performance of the floor 600. The multiple flooring materials include plywood 610 and flooring (finishing material) 640. The multiple soundproofing plate-shaped members include reinforced gypsum board (gypsum board) 620 and soundproofing sheet (soundproofing sheet) 630.

The multiple soundproofing plate-shaped members may be arranged between a floor material and another floor material. That is, the reinforced gypsum board 620 and the soundproofing sheet 630 may be arranged between a plywood 610 and another plywood 610.

According to this embodiment, the construction accuracy of the floor 600 can be improved while improving the soundproofing performance of the floor 600.

The multiple soundproofing plate-like members may each have a different thickness. That is, the thickness of the reinforced gypsum board 620 may be different from that of the soundproof sheet 630, the thickness of the reinforced gypsum board 620 may be different from that of another reinforced gypsum board 620, or the thickness of the soundproof sheet 630 may be different from that of another soundproof sheet 630.

The thicker the reinforced gypsum board 620, the better its sound insulation performance. However, the reinforced gypsum board 620 has a property that the sound insulation performance for sounds of a specific frequency corresponding to the thickness decreases due to the coincidence effect. Therefore, by stacking multiple reinforced gypsum boards 620 of different thicknesses, the decrease in sound insulation performance due to the coincidence effect can be mutually compensated for. Therefore, by stacking multiple reinforced gypsum boards 620 of different thicknesses, sounds of various frequencies can be efficiently attenuated. The same can be said for the sound insulation sheet 630.

In particular, the floor 600 may be laminated in the following order from the bottom: plywood 610, reinforced gypsum board 620, sound insulation sheet 630, reinforced gypsum board 620, sound insulation sheet 630, reinforced gypsum board 620, plywood 610, and flooring 640. In this way, the sound insulation sheet 630 may be placed between two reinforced gypsum boards 620. At this time, the floor 600 may be laminated in the following order from the bottom: plywood 610 with a thickness of 12 mm, reinforced gypsum board 620 with a thickness of 21 mm, sound insulation sheet 630 with a thickness of 4 mm, reinforced gypsum board 620 with a thickness of 15 mm, sound insulation sheet 630 with a thickness of 4 mm, reinforced gypsum board 620 with a thickness of 12.5 mm, plywood 610 with a thickness of 12 mm, and flooring 640 with a thickness of 16 mm. Here, the thickness of the reinforced gypsum board 620 is thinner in the upper layer than in the lower layer. In other words, the multiple soundproofing plate members may be configured so that the upper layers are thinner than the lower layers.

The laminated structure of the soundproofing plate-like member as described above is constructed so that the upper layer is thinner than the lower layer, thereby reducing the weight on the lower layer and allowing the lower layer to more reliably support the upper layer. In addition, the laminated structure of the floor 600 as described above is a dry laminated structure, which allows for weight reduction while improving the construction accuracy of the floor 600.

The joints of the multiple flooring materials and multiple soundproofing plate-like members may be arranged so that they do not overlap in the vertical direction. This arrangement of the joints will be described with the north side of the soundproofing structure 100 as the reference for the start of the joints. For example, (1) in the plywood 610, the start of the joint is 1 cm, and the joint spacing is 90 cm. (2) in the reinforced gypsum board 620, the start of the joint is 30 cm, and the joint spacing is 90 cm. (3) in the soundproofing sheet 630, the start of the joint is 60 cm, and the joint spacing is 90 cm. By arranging the joints as in (1) to (3) above, it is possible to configure the joints so that they do not overlap in the vertical direction.

In other words, when joints overlap, sound that enters the joint is easily propagated through the joint. Therefore, by preventing joints from overlapping and blocking the sound that enters the joint, it is possible to effectively suppress the propagation of sound.

1-8. Continuous ventilation duct 700
FIG. 5 is a diagram showing the configuration of the constant ventilation duct 700.

The constant ventilation duct 700 is a duct used in a constant ventilation system (so-called 24-hour ventilation system). The constant ventilation duct 700 is connected to a ventilation device 710 and includes an air supply duct 720 and an exhaust duct 730. The air in the room and the outside air are replaced within a predetermined time by the air supply and exhaust control performed by the ventilation device 710. The constant ventilation duct 700 is arranged between the building frame 200 and the ceiling 300 through a hole in the ceiling 300. The constant ventilation duct 700 extends from the connection with the ventilation device 710 toward the outside of the soundproof structure 100. A gap filler and airtight soundproof caulking may be applied to the gap between the constant ventilation duct 700 and the ceiling 300. The constant ventilation duct 700 may be made of, for example, a galvanized iron plate.

The length of the constant ventilation duct 700 is at least half the length of the side of the contact surface where the ceiling 300 and the wall 400 come into contact. That is, for example, if the length of the side formed by the contact surface where the ceiling 300 and the wall 400 come into contact on the north side of the soundproof structure 100 is 10 m, the length of the constant ventilation duct 700 may be at least 5 m. Specifically, for example, 5, 5.2, 5.4, 5.6, 5.8, 6, 6.2, 6.4, 6.6, 6.8, 7, 7.2, 7.4, 7.6, 7.8, 8, 8.2, 8.4, 8.6, 8.8, 9, 9.2, 9.4, 9.6, 9.8, 10, 10.2, 10.4, 10.6, 10.8, 11, 11.2, 11.4, 11.6, 11.8, 12, 12.2, 12.4, 12.6, 12.8, 13, 13.2, 13.4, 13. 6, 13.8, 14, 14.2, 14.4, 14.6, 14.8, 15, 15.2, 15.4, 15.6, 15.8, 16, 16.2, 16.4, 16.6, 16.8, 17, 17.2, 17.4, 17.6, 17.8, 18, 18.2, 18.4, 18.6, 18.8, 19, 19.2, 19.4, 19.6, 19.8, 20 m or more, and may be within a range between any two of the numerical values exemplified here.

Here, a comparison will be made with virtual duct 740, which is a virtual duct. Virtual duct 740 is configured to have approximately the shortest distance from the air intake or exhaust port that is in contact with the outside of soundproof structure 100 to ventilation device 710. On the other hand, constant ventilation duct 700 is configured to have a greater distance from the air intake and exhaust port to ventilation device 710 compared to virtual duct 740. Therefore, sound propagating within constant ventilation duct 700 is attenuated according to the distance it takes to reach the air intake and exhaust port.

2. Operation In Section 2, the operation of this embodiment will be described.

Figure 6 shows the state in which sound is generated inside the soundproof structure 100.

In FIG. 6, a drum 800 is illustrated as an example of a sound source. When sound 810 is generated from the drum 800, the sound 810 propagates toward each structure of the soundproof structure 100. The soundproofing effect of each structure of the soundproof structure 100 will be described below.

2-1. Soundproofing effect of the ceiling 300 The sound 810 reaches the rock wool sound absorbing board 340 in the ceiling 300. The sound 810 is absorbed by the rock wool sound absorbing board 340, and attenuates by the amount of sound absorption. Next, the sound 810 reaches the hard gypsum board 330. The sound 810 is insulated by the hard gypsum board 330, and attenuates by the amount of sound insulation. Next, the sound 810 reaches the sound insulation sheet 320. The sound 810 is insulated by the sound insulation sheet 320, and attenuates by the amount of sound insulation. Next, the sound 810 reaches the reinforced gypsum board 310. The sound 810 is insulated by the reinforced gypsum board 310, and attenuates by the amount of sound insulation.

The sound 810 then reaches the glass wool (not shown). The sound 810 is absorbed by the glass wool, and attenuates accordingly. The sound 810 then reaches the structure 200. The sound 810 is insulated by the structure 200, and attenuates accordingly. After going through the above soundproofing process, the sound 810 reaches the outside of the soundproof structure 100 (outdoors or an adjacent dwelling).

As a result, the ceiling 300 acts to attenuate the sound 810 propagating upward from the drum 800.

2-2. Soundproofing effect of wall 400 Sound 810 reaches the wallpaper 440 in the wall 400. Next, the sound 810 reaches the hard gypsum board 430. The sound 810 is insulated by the hard gypsum board 430 and attenuates by the amount of sound insulation. Next, the sound 810 reaches the sound insulation sheet 420. The sound 810 is insulated by the sound insulation sheet 420 and attenuates by the amount of sound insulation. Next, the sound 810 reaches the reinforced gypsum board 410. The sound 810 is insulated by the reinforced gypsum board 410 and attenuates by the amount of sound insulation.

The sound 810 then reaches the glass wool (not shown). The sound 810 is absorbed by the glass wool, and attenuates accordingly. The sound 810 then reaches the structure 200. The sound 810 is insulated by the structure 200, and attenuates accordingly. After going through the above soundproofing process, the sound 810 reaches the outside of the soundproof structure 100 (outdoors or an adjacent dwelling).

As a result, the wall 400 acts to attenuate the sound 810 propagating horizontally from the drum 800.

2-3. Soundproofing effect of floor 600 Sound 810 reaches flooring 640 in floor 600. Next, sound 810 reaches plywood 610. Sound 810 is insulated by plywood 610 and attenuates by the amount of sound insulation. Next, sound 810 reaches reinforced plasterboard 620. Sound 810 is insulated by reinforced plasterboard 620 and attenuates by the amount of sound insulation. Next, sound 810 reaches sound insulation sheet 630. Sound 810 is insulated by sound insulation sheet 630 and attenuates by the amount of sound insulation. Next, sound 810 reaches reinforced plasterboard 620. Sound 810 is insulated by reinforced plasterboard 620 and attenuates by the amount of sound insulation.

Then, sound 810 reaches sound-proofing sheet 630. Sound 810 is insulated by sound-proofing sheet 630 and attenuates by the amount of sound insulation. Next, sound 810 reaches reinforced gypsum board 620. Sound 810 is insulated by reinforced gypsum board 620 and attenuates by the amount of sound insulation. Next, sound 810 reaches plywood 610. Sound 810 is insulated by plywood 610 and attenuates by the amount of sound insulation. Furthermore, vibrations of floor 600 caused by sound 810 are absorbed by vibration-proof rubber 500.

Sound 810 that passes through floor 600 reaches glass wool (not shown). Sound 810 is absorbed by the glass wool, and attenuates by the amount absorbed. Next, sound 810 reaches structure 200. Sound 810 is insulated by structure 200, and attenuates by the amount insulated. After going through the above soundproofing process, sound 810 reaches the outside of soundproof structure 100 (outdoors or an adjacent dwelling).

As a result, the floor 600 acts to attenuate the sound 810 propagating downward from the drum 800.

3. Others Although the embodiment of the present invention has been described above, the present invention is not limited to this, and can be modified as appropriate without departing from the technical concept of the invention.

As a first modification, the vibration-proof material is not limited to the vibration-proof rubber 500 made of natural rubber, but may be made of, for example, fluororubber, silicone resin, urethane resin, etc.

As a second variation, the constant ventilation duct 700 is not limited to being made of zinc-plated iron plate, but may be made of, for example, galvalume steel plate (registered trademark), stainless steel plate, polyvinyl chloride-coated steel plate, etc.

As a third variation, the finishing material is not limited to flooring 640, but may be, for example, carpet.

According to this embodiment, the floating floor, which is made by stacking multiple soundproofing plate-like members, can improve the soundproofing performance for adjacent dwelling units above and below. In other words, sound inside a structure such as a room has the tendency to propagate more in the vertical direction than in the horizontal direction, so sound can be attenuated efficiently. In addition, because the wall is separated from the building frame, vibrations caused by sound generated in the wall and propagating to the building frame can be attenuated.

(2) The soundproof structure described in (1) above, which includes a plurality of floor materials, and the plurality of soundproof plate members are disposed between the floor materials and the other floor materials.

In this manner, the flooring material acts to improve the construction accuracy of the soundproofing plate-shaped members.

(3) In the soundproofing structure described in (1) or (2) above, the multiple soundproofing plate members each have a different thickness.

In this manner, the reduction in sound insulation performance caused by the coincidence effect that occurs in the soundproofing plate-shaped member is compensated for by each other, and various sounds that pass through can be attenuated.

(4) In the soundproofing structure described in (3) above, the multiple soundproofing plate members are configured so that the upper layer is thinner than the lower layer.

This configuration not only attenuates sound but also improves the support performance of the floor.

This type of structure allows for a lighter soundproofing structure compared to wet floating floors made of concrete, etc.

(7) A soundproof structure according to any one of (1) to (6) above, wherein the plurality of soundproof plate-shaped members include gypsum boards and soundproof sheets.

This type of configuration allows for the use of materials suitable for soundproofing.

In this manner, various sound frequencies can be efficiently attenuated by stacking components made of different materials in sequence.

This type of design improves sound insulation performance, allowing sound frequencies to be attenuated more efficiently than with sound-absorbing sheets.

(10) In the soundproof structure described in any one of (7) to (9) above, the flooring material includes plywood and a finishing material, and the floor is layered in the following order from the bottom up: plywood, gypsum board, soundproof sheet, gypsum board, soundproof sheet, gypsum board, plywood, and the finishing material.

In this manner, soundproofing plate-like members are placed between the plywood panels, improving the construction accuracy of the floor and efficiently attenuating various sound frequencies.

(11) A soundproof structure according to any one of (1) to (10) above, in which the ceiling is suspended from the structure.

In this manner, the ceiling is separated from the building structure, so that vibrations caused by sound generated in the ceiling that propagate to the building structure can be attenuated.

(12) A soundproofing structure according to any one of (1) to (11) above, further comprising a first vibration-proofing material disposed between the building frame and the floor and configured to deform in response to an impact applied to the floor to absorb the impact.

(13) A soundproofing structure according to any one of (1) to (12) above, further comprising a second vibration-proofing material, the second vibration-proofing material being disposed between the building frame and the ceiling and configured to deform in response to an impact applied to the ceiling, thereby absorbing the impact.

In this manner, the second vibration-proofing material can attenuate vibrations caused by sound generated in the ceiling that propagate to the building structure.

(14) A soundproof structure according to any one of (1) to (13) above, further comprising a constant ventilation duct, the constant ventilation duct being disposed between the building structure and the ceiling, and the length of the constant ventilation duct being at least half the length of the side of the contact surface where the ceiling and the wall come into contact.

According to this aspect, since the overall length of the duct can be secured, sound propagating within the duct can be efficiently attenuated before it reaches the outside.
Of course, this is not the case.
