Description

  The present invention relates to a soundproof panel, and more particularly to a soundproof panel that can be used as a wall or a door.

  In recent years, due to growing interest in the living environment, we have blocked the noise that occurs around us, such as the sound of vehicles such as cars and trains, the sound of musical instruments, and the noise of animals kept as pets, so as not to become noise, or Absorption is required. In order not to generate noise, it is necessary to surround a space where sound such as a wall or a door is generated with a soundproof panel. In recent years, soundproof panels having various structures have been developed.

  For example, a soundproof panel as shown in Patent Document 1 is disclosed. This soundproof panel accommodates a substantially elliptical capsule whose inside is vacuum between two plates forming a wall surface.

The structure is adopted.

  The present invention can provide a soundproof panel having excellent soundproofing efficiency by being configured as described above.

It is a figure which shows an example of the soundproof panel in this invention. It is a figure for demonstrating the internal structure of the soundproof panel disclosed in FIG. It is a figure which shows a mode when manufacturing the soundproof panel disclosed in FIG. It is a figure which shows the modification of the structure of the soundproof panel disclosed in FIG.

<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing an example of the configuration of a soundproof door using a soundproof panel according to the present invention. FIG. 2 is a diagram showing the internal structure of the soundproof door and the state of sound transmission. FIG. 3 is a diagram illustrating a method for manufacturing a soundproof door. FIG. 4 is a view showing a modification of the structure of the soundproof door.

  FIG. 1 shows a soundproof door 1 using a soundproof panel according to the present invention. The soundproof door 1 is used as a door of a room where a loud sound is output, such as a room where a musical instrument is played or a room where a pet such as a dog is kept. Therefore, although not shown, the door is provided with a door knob that is operated when the door is opened and closed. The door knob will be described later.

  The soundproof door 1 disclosed in FIG. 1 includes a panel body 10 having a soundproof structure inside, and surface members 21 and 22 that cover both surfaces of the panel body 10. In addition, in FIG. 1, sectional drawing of the panel main body 10 is shown. Hereinafter, the configuration of the soundproof door 1 will be described in detail.

  FIG. 2A is an enlarged partial sectional view of the soundproof door 1 constituted by the panel body 10 and the surface members 21 and 22. The panel main body 10 has a substantially rectangular parallelepiped shape, specifically, a plate shape having a predetermined thickness, and has a rectangular cross section. And the panel main body 10 is equipped with the hollow member 11 in the center part, as shown in FIG. The hollow member 11 is formed, for example, by forming an aluminum plate into a rectangular parallelepiped shape (plate shape having a predetermined thickness) by welding so that the inside is hollow, and the internal space 11a formed inside is in a vacuum state. is there. And the valve | bulb which leads to the inside from the outside is provided in the predetermined location of the surface of the hollow member 11, and it is possible to make the internal space 11a into a vacuum state using a suction pump.

  In addition, a damping material 12 that is a material having a damping effect is attached to the periphery of the hollow member 11 having a substantially rectangular parallelepiped shape, that is, the entire surface thereof without any gap. For example, the damping material 12 is a material that has a viscosity and elasticity, such as rubber and silicon gel, and controls vibrations of solids. The damping material 12 may be any material as long as it has a damping effect.

  And the sound absorbing material 13 which is a material which has a sound absorption effect is affixed on the further periphery of the said damping material 12, ie, the whole surface of the said damping material 12, without a gap. For example, the sound absorbing material 13 is a foamable material such as urethane foam or sponge, and is a material having a function of absorbing sound transmitted by air vibration. The sound absorbing material 13 may be any material as long as it has a sound absorbing effect.

  As described above, the panel main body 10 has a rectangular parallelepiped shape, and the vibration damping material 12 and the sound absorbing material 13 are laminated and attached to the outer surface of the hollow member 11 having a vacuum inside, in other words, the hollow member The laminated member which has the vibration suppression effect and the soundproofing effect is affixed on the outer surface of 11, and is comprised. The panel body 10 to which the damping material 12 and the sound absorbing material 13 are attached is also formed in a plate shape (a rectangular parallelepiped shape) having a predetermined thickness slightly larger than that of the hollow member 11. . In addition, the lamination | stacking order of the damping material 12 and the sound absorption material 13 is arbitrary, and may be laminated | stacked and provided in the reverse order. Further, the vibration damping material 12 and the sound absorbing material 13 may be provided in a plurality of layers, and other materials may be laminated.

  Here, since the internal space of the hollow member 11 located at the center of the panel body 10 is a vacuum, as shown in FIG. 3A, the center portion of the front and back surfaces 13a and 13b, that is, each side portion. The part away from is a shape recessed inside. In other words, the panel body 10 is formed in a plate shape having a predetermined thickness, but each of the mutually facing surfaces 13a and 13b forming the widest plate surface has a concave shape recessed in the inner direction. Become. Therefore, the surface of the panel main body 10 is formed flat by processing such as cutting or cutting the sound absorbing material 13 located on the recessed surface. That is, as shown by the dotted line in FIG. 3A, the sound absorbing material near each side of the panel member 13 that is a rectangular parallelepiped so that the surfaces 13a and 13b of the sound absorbing material 13 positioned on the outermost surface of the panel body 10 are flat. 13 is shaved in the thickness direction. Thereby, as shown in FIG. 3B, the thickness of the sound absorbing material 13 is not constant, and specifically, the thickness of the sound absorbing material 13 in the vicinity of each side of the panel member 13 is formed thinner than the vicinity of the center. However, the surfaces 13a and 13b in the entire panel body 10 are flat.

  In addition, although the case where the sound-absorbing material 13 was shaved was illustrated above, since the surface of the panel main body 10 should just become flat, you may grind and level the damping material 12 located in the lower layer of the sound-absorbing material 13. In this case, at the stage where the damping material 12 is pasted around the hollow member 11, a process such as shaving or cutting is performed so that the surface of the damping material 12 becomes flat, and then the flat damping material is applied. A sound absorbing material 13 having a uniform thickness may be attached to the surface of the vibration material 12. It should be noted that the surface of the panel body 10 may be finally flattened by machining other materials to be laminated.

  Then, on the surfaces 13a and 13b forming the widest surface of the panel main body 10, as shown in FIG. 2 (A), surface members 21 and 22 such as a stainless material forming the surface of the sound absorbing door 1 are provided. Each is provided by being pasted. In addition, the surface of these surface members 21 and 22 may be further painted or wallpaper may be affixed.

  Moreover, although not shown in figure, the valve | bulb provided in the hollow member 11 as mentioned above will be in the state which penetrated the damping material 12, the sound-absorbing material 13, and also the surface members 21 and 22 and was exposed outside. That is, the vibration damping material 12, the sound absorbing material 13, and the surface members 21 and 22 are formed with bubble holes that allow the valve to be exposed to the outside corresponding to the position of the valve provided in the hollow member 11. Has been. Thereby, even after manufacturing the soundproof door 1, the internal space of the hollow member 11 located inside can be made into a vacuum state through the valve | bulb exposed outside.

  Although not shown in FIG. 1, the sound absorbing door 1 is provided with an operation unit for operating a door such as a door knob. However, the sound absorbing door 1 in this embodiment is equipped with only one side to open and close. The door knob and the key, that is, the operation unit that can be locked and unlocked are attached. For example, a gremon lock is attached to one surface of the sound absorbing door 1, and a roller tightening handle lock is provided on the other surface. Accordingly, since the door can be opened and closed without using a door knob that is attached by being penetrated in the thickness direction of the door 1, the panel body 10, that is, the hollow member 11 whose inside is vacuum is provided in the entire soundproof door 1. Can be used.

  The sound absorbing door 1 configured as described above operates as shown in FIG. That is, as indicated by the solid line arrow in FIG. 2B, the sound input from the upper surface side first tries to be transmitted to the hollow member 11 provided therein. However, sound that can be transmitted to the hollow member 11 is first attenuated by the sound absorbing material 13 and can absorb a certain proportion of sound. Further, even if vibration due to sound is transmitted to the hollow member 11, it is absorbed by the sound absorbing material constituting the laminated member (see dotted line arrow). Further, since the hollow member 11 has a vacuum inside, no sound is transmitted to the other surface through the hollow portion (see the dotted arrow).

  Therefore, by using the panel body 10 described above, it is possible to efficiently absorb sound transmitted from one surface of the soundproof door 1 to the other surface, and to provide a soundproof door having a high soundproofing effect.

  And especially the soundproof door 1 in this embodiment is the one panel main body 10 (The hollow member 11 in which the damping material 12 and the sound-absorbing material 13 were provided) with the substantially same shape as the magnitude | size of the said door with respect to one door. ) Is used, the connection portion between the one surface and the other surface of the door is reduced, and transmission of sound can be further suppressed. Moreover, since the panel main body 10 is one, the vacuum of the hollow member 11 becomes easy, manufacture and maintenance of the soundproof door 1 are facilitated, and cost reduction can be achieved. Note that the present invention is not limited to the case where only one panel body 10 is provided in one soundproof door 1 or soundproof panel. That is, a plurality of panel bodies 10 may be provided inside one soundproof door 1 or soundproof panel.

  Here, another configuration of the soundproof door 1 having the above-described configuration will be described with reference to FIG. In the internal space 11a of the hollow member 11 located at the center of the panel main body 10 shown in this figure, a rib member 30 is provided for connecting between mutually facing surfaces. The rib member 30 is columnar. The rib member 30 has one end fixed to the inner side of one surface of the hollow member 11 with solder or the like, and the other end provided with a damping material 31 such as rubber on the inner side of the other surface of the hollow member 11. Is touching through. Thereby, it can suppress that the center part of the hollow member 11 dents, and can attain flattening of panel main body 10 itself. As a result, as described above, the process of flattening the surface of the panel body 10 is not required, or a minimum process is required, and the manufacture of the soundproof door 1 is facilitated, the cost is reduced, and the quality is improved. Can be achieved.

  The panel body 10 described above can be used not only as the soundproof door 1 but also as a soundproof wall.

<Embodiment 2>

In addition, the soundproof panel is configured, for example, by covering the one hollow member on which the laminated member is laminated with the surface member.

  According to the soundproof panel having the above configuration, the sound input to one surface of the soundproof panel is first transmitted to the hollow member in which the laminated members provided therein are laminated. Then, the transmitted sound is absorbed by the sound absorbing material constituting the laminated member. Even if the housing of the hollow member is vibrated by sound, the vibration is attenuated by the damping material laminated around the hollow member. Furthermore, since the hollow member has a vacuum inside, no sound is transmitted to the other surface of the soundproof panel. Therefore, the sound transmitted from one surface to the other surface can be efficiently absorbed through the hollow member itself, and a soundproof panel having a high soundproofing effect can be provided. And in particular, by configuring the soundproof panel using only one hollow member in which laminated members are laminated, the connection portion between one surface and the other surface is reduced, and transmission of sound is further suppressed. can do. In addition, the hollow member can be easily evacuated, the soundproof panel can be easily manufactured and maintained, and the cost can be reduced.

Specifically, in the soundproof panel, the hollow member has a substantially rectangular parallelepiped shape, and the thickness of the laminated member located near each side of the hollow member is thinner than the thickness of other portions of the laminated member. Has been. Furthermore, in the said sound-insulation panel, the structure that the rib member which connects between the mutually opposing surfaces of the said hollow member was provided in the inside of the said hollow member is taken.

  Thereby, since the hollow member has a vacuum inside, a part of the housing may be recessed due to negative pressure, but the surface of the hollow member can be formed flat by adjusting the thickness of the laminated member. Therefore, the surface member can be easily attached, the panel itself can be flattened, the cost can be reduced, and the quality can be improved. In addition, flattening can be further achieved by providing a rib member in the hollow member.

  In the above-described method for manufacturing a soundproof panel, a laminated member made of a damping material and a sound absorbing material is laminated around a hollow member whose inside is a vacuum, and the laminated member is covered with a surface member that forms the surface of the panel. The configuration is taken.

  And in the manufacturing method of the said sound-insulation panel, the structure of laminating | stacking the said laminated member on the said hollow member in order of a damping material and a sound-absorbing material is taken. Furthermore, in the manufacturing method of the said sound-insulation panel, after laminating | stacking the said laminated member around the said hollow member, the structure of forming the surface of the said laminated member flat is taken. Specifically, after laminating the laminated member around the hollow member having a substantially rectangular parallelepiped shape, the thickness of the laminated member located near each side of the hollow member is made thinner than other portions of the laminated member. And the structure of forming the surface of the said lamination | stacking member flat is taken.

  Even the invention of the method for manufacturing a soundproof panel having the above-described configuration has the same effect as that of the soundproof panel, and thus the above-described object of the present invention can be achieved.

  The soundproof panel in the present invention can be used for a wall or a door of a soundproof room, and has industrial applicability.
