Description

  The present invention relates to a vibration proof type soundproof door having both high sound insulation and vibration proofing function.

  When installing a soundproof door in a machine room or the like, it is necessary to consider two ways of sound transmission. That is, it is necessary to block air-propagating sound that is transmitted through the air by vibrating air and solid-propagating sound that is transmitted as vibration on the floor or wall. Solid-propagating sound is transmitted from the wall to the soundproof door through the door support, such as a soundproof door hinge, and the vibration is changed into sound at the door panel and radiated into the air. is there. For example, noise generated with the operation of a pump station for transferring, draining, or pressurizing fresh water, sewage, or other liquids, or other mechanical equipment propagates to the outside as air propagation sound and solid propagation sound.

  In such a case, in order to obtain a predetermined soundproofing performance, two functions of sound insulation of air propagation sound and reduction of solid propagation sound by vibration isolation are required. In addition, when a soundproof door is supported in a vibration-proof manner, an earthquake countermeasure different from that of a general door is required, and it may be required to have a mechanism for that purpose.

The conventional soundproof door is intended for sound insulation of air propagation sound, and the sound insulation is enhanced by thickening the door panel or filling the door panel with a sound absorbing material.
FIG. 15 shows a general conventional soundproof door intended only for sound insulation of air propagation sound. 15 (a) is a front view, FIG. 15 (b) is a longitudinal sectional view as seen in the direction AA of FIG. 15 (a), and FIG. 15 (c) is a cross section as seen in the BB direction of FIG. 15 (a). FIG. A door panel 10 is attached to a door frame 14 by a hinge 12. The door panel 10 is filled with a filler 16 such as glass wool for sound insulation. That is, the door panel 10 enhances sound insulation by sandwiching a sound absorbing material such as glass wool between two steel plates. A door packing 18 using an elastic body for preventing sound leakage is provided at a portion where the door panel 10 and the door frame 14 come into contact with each other. That is, in order to prevent sound waves from leaking through the gap between the door panel 10 and the door frame 14, the door packing 18 using an elastic body such as rubber is provided.

  Such a soundproof door can exhibit a predetermined sound insulating property against air propagation sound, but when the vibration of the device is propagating to the door, it prevents solid propagation sound generated from it. I can't. Therefore, even if the air propagation sound is sufficiently insulated, the noise may not be reduced to the target noise value due to the generation of the solid propagation sound.

  On the other hand, depending on the location where the door is installed, not only can sound insulation be improved and noise transmitted through the door panel can be suppressed, but also noise generated by opening and closing the door (a kind of “solid-borne sound”) can be suppressed. It may be necessary. For this reason, the following measures are taken.

  In patent document 1, the structure which affixes a vibration-proof material on the attachment metal fitting of a door frame, and is vibration-proof is disclosed. An object of the present invention is to prevent generation of vibration and impact sound due to opening and closing of a door. In other words, it is an object to prevent noise generated from the door itself from diffusing outside the door (for example, in an adjacent room).

In Patent Document 1, the door frame is in contact with the wall body via the vibration isolator at the place where the mounting bracket is attached. However, the door frame is in contact with the wall body outside this place. Is avoiding vibration propagation by contacting the wall body through a waterproof material made of an elastic material. However, in this structure, the elastic material receives the load of the door so that the frictional force against the elastic material and the force in the direction of shearing the elastic material work, and the elastic material is likely to be sheared or deteriorated. . Therefore, a heavy door cannot be installed.

  In Patent Document 2, a door frame mounting structure for a partition panel is devised in which a vibration isolating material is provided between the door frame and the opening over the entire periphery of the door frame. It is intended for relatively lightweight doors for partition panels. The object and the effect are the same as in Patent Document 1.

  Patent Document 3 discloses a door frame mounting structure characterized in that a buffer material is provided over the entire periphery of the door frame between the door frame and the opening of the building, as in Reference 2. The purpose and effect are the same as in Document 1. The purpose is to prevent noise propagation to the adjacent rooms and upper and lower floors, and relates to doors installed in buildings.

  Patent Documents 1 to 3 are all intended to prevent noise (door opening / closing sound, etc.) generated from the door itself from diffusing outside the door (for example, in the adjacent room). The door. Therefore, no countermeasure is taken against noise that propagates from the noise source inside the room (inside the room) through the door itself to the outside (outside the room).

  In Patent Document 4, one soundproof door is constituted by two door panels, and solid propagation sound is removed by supporting one of the two door panels so as to surround the periphery of the door panel with a vibration isolating material. A soundproof door is disclosed. It is said that the anti-vibration material is not exposed on the door surface, so it has excellent fire resistance. An object of the present invention is to provide a structure for blocking noise from outside in a studio or the like, and to suppress vibration generated in the door panel due to sound entering from the outside to the door panel by the structure. Noise is prevented from being transmitted to the inside. In patent document 4, it aims at prevention of the noise which enters into a room from the outside, and is not considered about the soundproof measure in case solid propagation sound is radiated outside.

  Patent Document 5 discloses a structure for attenuating vibrations generated in a door by constituting a column to which a hinge of a door is attached by using anti-vibration rubber at two upper and lower portions of the column following the column. The anti-vibration rubber is designed to cut off the sound and vibration associated with opening and closing the door. However, in this structure, since a load is not applied vertically (in the direction of gravity) to the anti-vibration rubber and a force in the bending direction may be applied, it is difficult to attach a heavy door. Moreover, in order to exhibit appropriate vibration-proof performance, it is necessary to adjust the compression amount of the upper and lower vibration-proof rubbers, but the structure of Patent Document 5 is difficult.

Next, with reference to the accompanying drawings, embodiments of the vibration-proof and soundproof door according to the present invention will be described in detail. In the following, the same reference numerals are assigned to the same members.
FIG. 1 is a diagram showing a schematic configuration of a vibration-proof soundproof door 20 according to an embodiment of the present invention. FIG. 1A is a front view, and FIG. 1B is a longitudinal sectional view as seen in the AA direction of FIG. The vibration-proof soundproof door 20 has a panel frame 24 attached to a door frame 22 which is a frame portion via a hinge 30, and a single sound-insulating panel 28 attached to the panel frame 24 via a vibration-proof material 26. . The panel frame 24 surrounds the outer periphery of the sound insulation panel 28 and has a U-shaped cross section. The vibration isolator 26 is disposed on four sides of the sound insulation panel 28. A vibration isolator 26 is disposed on the U-shaped portion of the panel frame 24. The anti-vibration material 26 surrounds each of the four sides of the sound insulation panel 28 in a U shape, and the lower portion of the sound insulation panel 24 is supported by the anti-vibration material 26 for anti-vibration while receiving the load of the sound insulation panel 28.

  In FIG. 1, the size of the anti-vibration material 26 is set so that the inner end portion 26 a of the anti-vibration material 26 is located at the same position as the inner end portion 24 a of the panel frame 24. In FIG. 1A, the inner end portion 26a of the vibration isolator 26 and the inner end portion 24a of the panel frame 24 are shown to coincide with each other. In FIG. 1A, four sides of the outer periphery 28a of the sound insulation panel 28 are indicated by dotted lines.

The anti-vibration material 26 is intended for vibration insulation, and the material thereof is an elastic material such as anti-vibration rubber, glass wool or rock wool.
The sound insulation panel 28 only needs to have sound insulation properties. For example, a cement board (also called “slate board”) can be used. A cement board is comprised from a cement and a fiber raw material. The panel frame 24 is made of a metal such as a steel plate or a high-strength plastic.

  The vibration-proof soundproof door 20 is fitted in the door frame 22, and the soundproof door 20 is supported by the door frame 22 with a hinge 30 like a normal door. A handle for opening and closing the soundproof door 20 is attached to the panel frame 24. The door frame 22 is fitted in and fixed to an opening in a wall (not shown).

  With the above structure, vibration generated in the room due to machine operation or the like is prevented from propagating from the door support (hinge 30) to the sound insulation panel 28, and solid propagation sound generated from the sound insulation panel 28 to the outside is suppressed. Can be reduced.

  FIG. 2 shows a schematic configuration of a vibration-proof and soundproof door 120 according to another embodiment of the present invention. 2A is a front view, and FIG. 2B is a longitudinal sectional view as seen in the AA direction of FIG. 2A. In the anti-vibration type soundproof door 120 of the present embodiment, the anti-vibration material 126 surrounds each of the three sides of the sound insulation panel 28 except the lower side in a U-shape, and is arranged on the lower side of the sound insulation panel 28. Is a plurality of independent anti-vibration rubbers 34.

  On the three sides excluding the lower side of the panel frame 24, a vibration-proof material 126 is disposed on the U-shaped portion. The lower part of the sound insulation panel 24 is supported by vibration isolation rubber 34 for vibration isolation. The anti-vibration material 126 surrounds each of the three sides except the lower side of the sound insulation panel 28 in a U-shape.

  For the anti-vibration rubber 34 which is the anti-vibration device at the lower part of the panel frame 24, an appropriate natural frequency is set after installation in consideration of the mass of the sound insulation panel 28 supported by the anti-vibration rubber 34 and the frequency of vibration to be anti-vibration. The spring constant of the anti-vibration rubber 34 is selected so that the anti-vibration rubber 34 has.

  The natural frequency (resonance frequency) of the vibration isolating rubber 34 is determined by the spring constant and the number of the vibration isolating rubber 34 and the mass of the sound insulation panel 28 to be supported. That is, the natural frequency is determined from the compression amount of the vibration-proof rubber 34. The amount of compression of the anti-vibration rubber 34 is set so that this natural frequency is different from the frequency of the vibration to be anti-vibrated. As a result, vibration can be prevented from being transmitted from the panel frame 24 to the sound insulation panel 28.

  In this embodiment, since the vibration isolator can be designed according to the frequency of the vibration to be anti-vibrated, for example, if the frequency of the vibration generated from a nearby machine is known, the vibration is efficiently prevented. be able to.

  An example of a specific method for attaching the vibration-proof rubber 34 is shown in FIGS. 3 (a) and 4 (a) show anti-vibration rubber parts 34a and 34b before installation, and FIGS. 3 (b) and 4 (b) show anti-vibration rubber parts 34a and 34b after installation. Show. The anti-vibration rubber component 34a of FIG. 3 has the anti-vibration rubber 34 attached to the bottom plate 36, and the bottom plate 36 has two through holes 38 for bolts. A plate 42 to which bolts 40 are attached is attached to the upper part of the vibration isolating rubber 34. As a mounting procedure, the bottom plate 36 of the vibration-proof rubber component 34a is fixed to the panel frame 24 with a nut 44 using a bolt. Next, the sound insulation panel 28 is positioned and positioned on the vibration isolating rubber part 34 a, and is fixed to the sound insulation panel 28 with a nut 46 using a bolt 40. The sound insulation panel 28 has a space for access so that the nut 46 can be rotated.

In the anti-vibration rubber component 34b of FIG. 4, the anti-vibration rubber 34 is attached to the bottom plate 36a, and a bolt 48 is attached to the bottom plate 36a. A plate 42 to which bolts 40 are attached is attached to the upper part of the vibration isolating rubber 34. As an attachment procedure, the bolt 48 is passed through a through hole provided in the lower part 50 of the panel frame 24. Next, the bottom plate 36a of the anti-vibration rubber component 34b is fixed to the panel frame 24 with the nuts 44 using the bolts 48. The sound insulation panel 28 is positioned and positioned on the vibration isolating rubber 34 b, and is fixed to the sound insulation panel 28 with a nut 46 using a bolt 40. The sound insulation panel 28 has a space for access so that the nut 46 can be rotated.

  3 and 4, for the purpose of closing the gap between the side surface of the sound insulation panel 28 and the side surface of the panel frame 24 facing the side surface without receiving a load, and An elastic sealing material 51, which is a kind of vibration-proof material that does not transmit vibration, can be inserted.

The elastic sealant is a silicon sealant or a polysulfide sealant.
5 and 6 show a schematic configuration of a vibration-proof type soundproof door according to another embodiment of the present invention. FIG. 5 is a longitudinal sectional view of the lower part of the soundproof door. In the anti-vibration type soundproof door of this embodiment, the anti-vibration material surrounds the three sides of the sound insulation panel 28 except the lower side in a U-shape, as in FIG. The vibration isolation materials 52, 54, and 56 disposed on the lower side of the sound insulation panel 28 are U-shaped, but are not integrated and are divided into three parts. The vibration isolating materials 52, 54, and 56 are disposed on the front surface 58 and the back surface 60 of the sound insulation panel 28 and the lower surface 62 of the sound insulation panel 28.

  FIG. 6 shows the embodiment of FIG. 5 further provided with compression means for compressing the vibration isolating materials 52 and 54 disposed on the front surface 58 and the back surface 60. The purpose of compressing the anti-vibration materials 52 and 54 is the same as the reason why the anti-vibration rubber 34 is selected so as to exhibit the anti-vibration performance in FIG. That is, the compression amount of the vibration isolation materials 52 and 54 is set so that the natural frequency of the vibration isolation materials 52 and 54 is different from the frequency of the vibration to be vibration isolation. In FIG. 2, the anti-vibration rubber 34 is compressed by the load of the sound insulation panel 28, but in FIG. 6, the anti-vibration materials 52 and 54 are compressed by the compression means.

  The compression means includes a plate 64 that pushes the vibration isolator 54, a push bolt 68 that pushes the plate 64, and a fixing nut 70. The fixing nut 70 is fixed to the panel frame 24 by welding or the like. The compressive force applied to the vibration isolation materials 52 and 54 is set by setting the distance between the head of the push bolt 68 and the fixing nut 70.

  FIG. 7 shows a schematic configuration of a vibration-proof type soundproof door according to another embodiment of the present invention. FIG. 7 is a longitudinal sectional view of the lower part of the soundproof door. In this embodiment, as in the embodiment of FIG. 5, the vibration isolating material surrounds the three sides of the sound insulation panel 28 except for the lower side in a U shape, and is disposed on the lower side of the sound insulation panel 28. , 54 and 56 are arranged on the front surface 58 and the back surface 60 of the sound insulation panel and the lower surface 62 of the sound insulation panel. The anti-vibration materials 52 and 54 disposed on the front surface 58 and the back surface 60, the panel frame 24, and the sound insulation panel 28 are penetrated, and the anti-vibration materials 52 and 54, the panel frame 24, and the sound insulation panel 28 are fixed to each other. It has a fixing member. The fixing member has at least one of the effects of preventing the vibration isolating materials 52 and 54 and the sound insulation panel 28 from falling off, taking measures against earthquakes, and setting the compressive force on the vibration isolating materials 52 and 54.

  The fixing members include bolts 72 that pass through the vibration isolating materials 52 and 54, the panel frame 24, and the sound insulation panel 28, nuts 74, washers 76 and 78, and vibration isolating materials 80 and 82. By adjusting the tightening amount by the bolt 72 and the nut 74, the compression amounts of the vibration isolating materials 52 and 54 and the vibration isolating materials 80 and 82 are changed, and the vibration isolating materials 52 and 54 and the vibration isolating materials 80 and 82 are inherently separated. Change the frequency. As a result, vibration can be effectively prevented. In this case, the panel frame 24 has a rigidity that causes deformation to such an extent that the vibration-proof materials 52 and 54 are compressed by tightening the bolts 72 and the nuts 74.

  Further, when wind load acts on the door panel and the door panel is pushed or pulled in the horizontal direction, the vibration isolation materials 52 and 54 and the vibration isolation materials 80 and 82 are pre-compressed with bolts and nuts. Even if the position of the door is slightly moved by the wind pressure, either the vibration isolator 52 or the vibration isolator 54 increases in compression amount and the other compression amount decreases, but within the range of the compression amount given in advance. If so, both will remain compressed.

  In general, a vibration-proof material cannot exhibit vibration-proof performance unless it is compressed by a length determined for each product. If it is not compressed in advance, if the compression amount of either the vibration isolator 52 or the vibration isolator 54 is too small or too small due to the wind pressure, the necessary vibration isolating performance cannot be exhibited, and the vibration propagates to the door panel, Solid propagation sound may occur. In the case of FIG. 7, such a problem can be prevented.

  In addition, as shown in FIG. 8, you may provide the door packing 18 which uses an elastic body for the sound leak prevention in the part which the panel frame 24 and the door frame 22 contact. Further, the panel frame 24 may have a back panel 84. The vibration isolator 86 is disposed not only on the outer periphery of the sound insulation panel 28 but also on the entire surface of the sound insulation panel 28 between the back panel 84 and the sound insulation panel 28. This is to improve sound insulation.

  FIG. 9 shows a schematic configuration of a vibration-proof and soundproof door 220 according to another embodiment of the present invention. FIG. 9 is a longitudinal sectional view of the soundproof door 220. The soundproof door 220 is integrated with a normal door 88 that does not have a vibration isolator. Specifically, the panel frame 224 of the door 88 has an extension frame portion 225. The sound insulation panel 28 is disposed on the outdoor side of a normal door 88 that does not have a vibration isolation portion via a vibration isolation material 286. In this embodiment, the anti-vibration material 286 includes an anti-vibration material 286 a disposed on the extension frame portion 225 and an anti-vibration material 286 b disposed between the door 88 and the sound insulation panel 28. The vibration isolator 286a and the vibration isolator 286b are integrated. The anti-vibration material 286a and the anti-vibration material 286b may be separate parts.

  FIG. 10 shows a schematic configuration of a vibration-proof type soundproof door 320 according to another embodiment of the present invention. FIG. 10A is an embodiment in which the door opening / closing portion protrudes from the door frame when the door is closed, and FIG. 10B is an embodiment in which the door opening / closing portion is accommodated. Normally, door packing is attached to the soundproof door, but it may not be attached. FIG. 10 is a longitudinal sectional view of the soundproof doors 320 and 320a. In FIG. 10A, the sound insulation panel 28 protrudes out of the door frame 22. In FIG. 10B, the entire soundproof door 320 a is inside the door frame 22, and the sound insulation panel 28 does not jump out of the door frame 22.

  A shielding plate 324 for reducing noise is attached to the sound insulation panel (cement plate) 28 by screws 108, and a function of a vibration isolating material is provided between the frame portion of the door panel 90 of the normal door and the shielding plate 324. An elastic sealant 326 is disposed.

  The vibration-proof and soundproof doors 320 and 320a include a normal door panel 90, and the frame portion of the vibration-proof and soundproof doors 320 and 320a is a frame portion of the normal door panel 90. A sound insulation panel 28 is attached to a normal door panel 90 via a vibration isolation rubber 92 which is a vibration isolation member. The anti-vibration rubber 92 is attached to the outside of the normal door panel 90, that is, the outer surface.

  The soundproofing doors 320 and 320a are attached to a normal door 90 having no vibrationproofing properties via a vibration isolation rubber 92. Specifically, the vibration isolation rubber 92 includes a support member 94 and a bolt nut 96. Is attached to a normal door 90. A sound insulation panel 28 is attached to a normal door 90 via a vibration-proof rubber 92 and an elastic sealing material 326. Accordingly, it is possible to prevent solid propagation sound from being generated with respect to the normal door 90.

  As described above, in the embodiment of FIG. 10, the sound insulation panel 28 is attached to the panel frame of the normal door panel via the vibration isolating material. The shielding plate is attached to the sound insulation panel 28, and there is a gap between the door panel so that vibration is not transmitted from the door panel, but it is elastic so that sound does not leak from here (also serves as waterproofing). Filled with sealing material.

The shielding plate is attached to the sound insulation panel side, but in some cases, the shielding plate may be attached to the door panel. Since the sound insulation panel and the door panel need to be vibration-insulated, leave a gap somewhere. At that time, an elastic sealing material or the like is filled to prevent sound leakage. Therefore, the shielding plate does not support the sound insulation panel. The panel frame supports the panel, and in this embodiment, the shielding plate is intended to prevent sound leakage from various gaps and does not support anything.

  In manufacturing, it is possible to make the panel frame and the shielding plate integrally, but their purpose is different, basically the panel frame is attached to the door frame, and the shielding plate is attached to the sound insulation plate (cement plate) Therefore, it is not integrated in this embodiment.

There are various attachment methods for the shielding plate. In this embodiment, the shielding plate is attached to the sound insulation panel, and the gap with the door panel or the like is filled with an elastic sealing material.
Note that the vibration-proof soundproof door of the present invention can be used as a door of a building, or can be used by being fitted into a part of a sound insulating wall installed outside the building as a soundproof door. Therefore, it is possible to improve the soundproofing performance by preventing the solid propagation sound only for the building door, and when it is fitted as a soundproof door to a part of the sound insulation wall, the solid propagation sound of the door installed on the sound insulation wall is It is possible to improve the soundproofing performance.

Next, various configuration examples of the door panel will be described. FIG. 11 shows various configuration examples of the sound insulation panel according to the present invention.
What is shown in FIG. 11A is that shown in FIG. The door shown in FIG. 1 and FIG. 1 is obtained by inserting a cement plate 97 into a panel frame 24 made of steel plate, and the sound insulation panel 28 is attached to the panel frame 24 made of steel plate. As shown in this figure, the sound insulation panel 28 can be improved in sound insulation by using a cement plate 97 having a high density.

As in another example shown in FIG. 11 (b), the sound insulation panel 128 of the soundproof door is composed of a steel plate 98 covering the entire outside and a filler 100 filled in the steel plate 98. As the filler, glass wool with a relatively high density (about 32 kg / m ³ ) or rock wool (about 80 kg / m ³ ) is used.

In yet another example shown in FIG. 11C, the sound insulation panel 128a has a cement plate 97 disposed inside a steel plate 98 covering the entire outside.
In addition, the surface of the sound insulation panel can be made suitable in terms of design, such as matching the outer wall of a building or finishing like a general door.

  FIG. 12 shows still another various configuration examples of the sound insulation panel according to the present invention. In FIG. 12, the entire outside of the sound insulation panel 128 is formed into a multilayer panel composed of the damping steel plate 102 and the sound insulation sheet 104. In these, the damping steel plate 102 is arranged in the outermost layer and the sound insulation sheet 104 is arranged on the inner side, and the sound insulation performance is slightly lowered, but it is on the front side of the sound insulation panel as a method for making the door as light as possible. The steel plate portion was made into a thinner damping steel plate 102 to form a multilayer panel in order to compensate for the decrease in sound insulation performance.

As a material for the sound insulation sheet, a hard plastic or a hard rubber plate can be used.
In FIG. 12A, by installing the cement plate 97 inside the sound insulation sheet 104, the sound insulation is not lowered while the mass is reduced. FIG. 12B shows the sound insulation sheet 104 filled with a filler 106 such as glass wool. In FIG. 12C, the same sound insulation sheet 104 as in FIG. 12A includes a cement plate 97a thinner than that shown in FIG. 12A, and the filler 106 is disposed around the cement plate 97a. By doing so, the sound insulation is not lowered while reducing the mass.

  FIG. 13 shows a schematic configuration of a vibration-proof and soundproof door according to another embodiment of the present invention. When a cement board is used, the door panel becomes heavy, so the load on the hinge when the door is opened and closed is large. Therefore, a caster mounting leg to which a caster is fixed is attached to the door panel surface on the door opening side.

  For example, the caster 112 with the rubber tire 110 is attached to the panel frame 224 via the caster mounting legs 114 as shown in FIG. 13 to the soundproof door 220 shown in FIG. In this case, the door 220 can be opened and closed while receiving the load of the door 220 on the floor 116, and the vibration is attenuated by the rubber tire 110, so that the vibration propagates from the floor surface to the door 220 and solid propagation sound is generated. There is nothing. Further, by using the rubber tire 110, there is no hindrance to opening and closing the door 220 even if the floor surface has some unevenness. Further, since the load on the hinge is reduced, it is possible to prevent problems such as a decrease in durability and the inability to smoothly open and close.

  FIG. 14 shows a schematic configuration of a vibration-proof and soundproof door 420 according to another embodiment of the present invention. 14A is a cross-sectional view taken along the line AA in FIG. 14B, and FIG. 14B is a front view. The present embodiment is similar to the embodiment of FIG. 10A, but in this embodiment, a vibration proof rubber 92 is attached to the inside of the door panel 190 to support the sound insulation panel (cement board) 28. This is different from the embodiment of FIG. The sound insulation panel 28 does not protrude from the door frame without increasing the depth of the door frame, as compared with the embodiment of FIG. When the depth of the door frame 422 can be made larger than the door frame 422 shown in FIG. 14A, the sound insulation panel 28 can be housed in the door frame.

  A shielding plate 424 for reducing noise is attached to the sound insulation panel 28, and an elastic sealing material 426 having a function of a vibration isolating material is disposed between the frame portion of the door panel 190 of the normal door and the shielding plate 424. Has been.

  The vibration-proof soundproof door 420 includes a normal door panel 190, and the frame portion of the vibration-proof soundproof door 420 is a frame portion of the normal door panel 190. A sound insulation panel 28 is attached to a normal door panel 190 via a vibration isolation rubber 92 which is a vibration isolation member. The anti-vibration rubber 92 is attached to the inside of the normal door panel 190, that is, the inner surface. In particular, it is attached to the inner surface of the indoor panel 190a.

  The soundproof door 420 is attached to a normal door 190 that does not have sound insulation properties via a vibration isolation rubber 92. Specifically, the vibration isolation rubber 92 is a normal member by a support member 94 and a bolt nut 96. Attached to the door 190. A sound insulation panel 28 is attached to a normal door 190 via a vibration-proof rubber 92 and an elastic sealing material 426. Accordingly, it is possible to prevent solid propagation sound from being generated with respect to the normal door 90.

The interior of the door panel 190 can be either hollow or solid. In the case of the solid, only the portion to which the anti-vibration rubber 92 is attached is provided with a space.
As described above, in the embodiment of FIG. 14, the shielding plate is attached to the panel frame of the normal door panel via the vibration isolator. The shielding plate 424 is attached to the sound insulation panel 28, and there is a gap between the door panel so that vibration is not transmitted from the door panel, but the sound does not leak from here (also serves as waterproofing). An elastic sealant 426 is filled.

  By the way, in this invention, you may give the following additional structures to a soundproof door. By attaching a reinforcing material such as a turnbuckle or diagonal to the sound insulation panel shown in FIG. 2 and the like, even a heavy sound insulation panel using a cement board can be given sufficient strength without deformation.

Moreover, sound insulation, dustproofness, and rainwater sealability (dripproofness) can be improved by duplicating the door packing.
Further, by making a relief hole for rainwater or the like in the lowermost structure of the panel frame, this can be drained even when rainwater or the like enters from the periphery of the panel frame.

  Moreover, it can also be set as the structure which can remove a door by setting it as the insertion / extraction hinge which can be inserted / extracted in the part of an axis | shaft. When a large device is carried in / out through a door in a machine room or the like, the operation becomes easy.

  In addition, it is possible to improve the security by attaching a key to the door, or to attach a rod rod that fixes the door to the floor surface in conjunction with the handle. The rod bar is fixed in a hole provided on the floor surface, so that the closed state of the door becomes stronger and the sound insulation is improved.
