Description of the Related Art A conventional soundproofing material utilizing vacuum is used, for example, in Japanese Patent Application No. 48-85289, Japanese Patent Application No. 52-91828, Japanese Patent Application No. 5-151688 to hold a vacuum layer. Core and Japanese Patent Application No. 6-101916
Such a block member is inserted as a space maintaining member for the airtight material. Therefore, when the sound is radiated from the back surface of the sound receiving surface material, the sound is not transmitted in the vacuum portion, but in the gap holding material portion such as the honeycomb core and the frame member, the sound is transmitted as vibration inside the material, and the sound is emitted. The airtight material emits sound.

Therefore, the spacing member influences the performance as a vacuum soundproofing material, but in the honeycomb core and many block members, the ratio of the contact length of the spacing member to the area of the hermetic material is large, and the performance of the hermetic material is large. Since there are many contact points of the spacing member, many vibrations are transmitted, and there is almost no vibration damping between the sound receiving surface and the sound emitting surface, which reduces the soundproofing effect.

[0004]

The problem to be solved is that in the vacuum soundproof material, the amount of vibration transmitted by the spacing member between the sound receiving surface and the radiation surface is large.

[0005]

[Means for Solving the Problems] Therefore, the vibration transmission amount

[0035]

The soundproofing material utilizing the vacuum has the following features.
There are performances that cannot be obtained with conventional soundproofing materials. Sound insulation and sound absorption can be performed at the same time, thickness is not affected, high sound insulation and sound absorption effect can be obtained even at light weight, high sound insulation performance can be obtained even at low frequencies, and performance is the sum of the number of layers.

The conventional sound insulating material attenuates based on the mass law of sound, and the sound reaching the back surface is emitted as it is. Since the mass law improves the sound insulation performance by the logarithmic ratio of the weight of the material, for example, even if the thickness of the plate is doubled, there is only a performance improvement of about 1.3 times,
On the other hand, about 10 times the weight is required to obtain twice the sound insulation performance.

On the other hand, since a material having high sound insulation has a large amount of surface reflection sound, that is, reverberation, a thick sound absorbing material such as glass wool is required. Sound absorption performance is required.

[Claim 1] A force corresponding to the area acts on the vacuum body from the entire circumference toward the inside by atmospheric pressure. As a result, the bottom surface of the hard airtight material is pushed inward, but the continuous deformation in the vertical and horizontal directions or the reinforcing material reduces flexural deformation and maintains the shape of the vacuum body.

On the other hand, since the soft airtight material cannot resist the inward pressing by the atmospheric pressure by the face material itself, the pressure is applied to the hard airtight material through the bent pieces of the joined hard airtight material. . As a result, the total pressure exerted by the lightweight airtight material becomes a force that pulls the bent piece inward, which translates into a force that tends to collapse inward.

In response to this force, the rib or the reinforcing material is formed or attached so as to be integrated from the bottom surface to the rising surface, so that the deformation is slight and the shape of the vacuum body is maintained.

When using a vacuum body, always place a lightweight hermetic surface in the direction of sound. When the lightweight airtight material receives sound, a very slight sound is transmitted as vibration from the airtight material to the bent piece on the outer peripheral portion, and is radiated as sound into the vacuum and the atmosphere on the back surface.

On the other hand, the sound received by most of the area except the outer peripheral portion is replaced with energy for vibrating the lightweight airtight material. The lighter the airtight material, the easier it is to vibrate, and the energy is emitted to the back surface without being attenuated. If there is air on the back side, it will be transmitted as sound, but since it is a vacuum, it cannot be transmitted as sound.

As a result, most of the energy is not replaced by sound, but is changed to thermal energy due to vibration, so that the soundproof material is capable of high-performance sound insulation and sound absorption at the same time.

[Claim 2] When the vacuum body of Fig. 2 (a) is used outdoors like a soundproof wall, when a large bending force acts in the long side direction due to wind pressure or one side has a long shape. , The whole becomes easier to twist,
In order to prevent deterioration of shape stability, bent pieces are provided in the long side direction.

As a result, the total bending in the direction of the long side is significantly reduced, so that the deformation of the vacuum body can be reduced. Also, since the end is wide due to the shape of the reinforcing plate,
When it is used by dropping it into a groove of a column having grooves on both sides like H-shaped steel, the mounting work is easy by adjusting the bending length of the reinforcing plate to the groove width. In addition, since the sound of the bent piece has sound insulation performance based on the sound mass law,
The narrower the width, the better.

About curved vacuum bodies. Noise suppression measures for the sound emitted from the vibrator for compacting the ground using compressed air and the pile driving machine of the diesel engine are effective measures with the conventional soundproof method because the sound is emitted from the exhaust opening of the engine. I couldn't. On the other hand, the vacuum sound absorbing material absorbs sound, and because it is lightweight and thin, even if it is installed as a cover for these machines with a gap that allows air to be exhausted, the work noise is reduced and the hearing loss of workers is prevented. Can improve the working environment and the sound environment around the work place. The cover may not be a cylinder, but may be only the cover of the exhaust portion.

Sound absorbing materials used in tunnels and subways are targeted for sound absorption. However, sound absorbing materials such as glass wool require a large thickness space and are difficult to use in the presence of running water.
On the other hand, since the vacuum body is thin and has water resistance and fire resistance, it can be used and can be a quiet tunnel.

[Claim 3] When a lightweight airtight material is used as the sound receiving side, the back surface of the vacuum body having the ribs becomes the side that is visible to human eyes, which is not preferable in terms of design. In order to improve this, it is possible to provide a design suitable for the place of use by attaching a cover according to the design.

[Claim 4] A conventional sound deadening box based on the mass law has a large size because a thickness of about 5 cm is required in the method of combining a metal plate and a sound absorbing material such as glass wool. In contrast,
The use of a vacuum body makes it possible to provide a lightweight and small-sized product because it is lighter in weight and thinner than a soundproof material according to the mass law.

[Claim 5] Regarding the partition wall. In order to obtain high sound insulation by the conventional method, several plaster boards and lead sheets are overlaid on both sides of the upper and lower frames and the vertical frame while providing an air layer, and a glass roux is inserted in the space. Therefore, due to the increase in the weight of the building and the increase in assembling time, the cost and the construction period are lengthened. On the other hand, when a vacuum body is used, it is lightweight and can simultaneously perform sound insulation and sound absorption, and has high sound insulation performance. Therefore, the wall thickness becomes thin and the room expands, and the weight of the building and the construction period can be shortened.

[Claim 6] Regarding the soundproof floor structure. When the floor laying method shown in FIG. 8A is used, sound reverberates between the support floor and the floor panel, and the sound insulation performance deteriorates. Therefore, glass wool or plastic foam is inserted to absorb the echo. However, these materials have the ability to absorb the echo sound and have no effect of insulating the sound generated from the floor panel. On the other hand, if a vacuum soundproof material is used, not only the reverberant sound but also the direct sound is absorbed, resulting in a high-performance soundproof floor.

The floor construction method of FIG. 8 (b) is used when sound and vibration of the engine are transmitted through the structural material and dissipated as sound from the floor into the room like a ship. In the past, there was no effective sound insulation method for such sounds, but when a vacuum body is used, the vacuum section does not transmit sound, so it becomes a high-performance soundproof floor and a quiet guest room. The cushioning material is for protecting the lightweight airtight material of the vacuum body and for preventing vibration transmission from the bent piece to the finishing floor.

[Claim 7] Regarding the soundproof panel. Regarding the surface material used for the surface of the soundproof panel, the non-perforated plate absorbs different frequencies depending on the size and hardness of the plate, but when the size exceeds a certain level, the plate vibrates and absorbs low-pitched sound well. To do. Also, as shown in FIG.
% About the perforated plate with open holes around%, it absorbs the sound in the middle range well. Therefore, by selecting a non-perforated plate or a perforated plate and using it in combination with a vacuum body, a soundproofing fitting or soundproofing panel with improved performance in a specific frequency band is obtained.

When used for fittings, hinges are attached to the vertical frame member or hinges to the upper and lower frames, doors are attached to the lower frame, sliding doors are attached to the lower frame, and hanging doors are attached to the upper frame. It is used as a partition panel by attaching fixing brackets to the upper and lower frames. Since the soundproof panel can be made lightweight, it can be easily installed, and can be moved lightly when it is used for a fitting or a movable soundproof panel from the floor to the ceiling.

[Claim 8] Regarding the soundproof wall. The sound insulation performance of conventional sound barriers is determined by the performance of the thickness of the steel plate. Therefore, it is the current situation that it is difficult to obtain the performance higher than that of the current situation due to the limitation of weight and thickness.
On the other hand, since the vacuum body is lightweight and has high sound insulation performance, it can be installed as a new sound insulation wall that does not meet environmental standards, or can be newly installed to form a sound insulation wall with high sound insulation performance.

The effects of sound using a vacuum have been described above, but the following effects are also provided. Under the conditions of use, the conventional soundproof panel generally uses glass wool as a sound absorbing material, but since it is a fiber, the place where it is splashed with water has only a resistance to the extent of the water repellent treatment. Therefore,
It cannot be used in places with running water, such as subway stations, because if it contains water, the sound absorbing effect will be lost.

On the other hand, since the soundproof panel of the present invention uses the airtight material for the vacuum body, it can be used not only in the subway but also in the water extremely. In other performance,
It has the advantages of weight reduction, fire resistance, water resistance, freeze-thaw resistance, etc. It can be used in unprecedented places, and its applications are expanded.

It is also effective against heat. Foamed plastics and glass wool, which are general heat insulating materials, are heat insulating materials that control the convection of air, so the heat insulating performance is determined in proportion to the thickness. In contrast, the use of vacuum results in radiation and heat transfer of the airtight support. Therefore, it becomes possible to perform heat insulation regardless of the thickness.

Since the present invention is mainly intended for soundproofing, the heat insulation is limited to the cutting heat ability obtained as a result of being manufactured for soundproofing. However, when the airtight material is metal, the surface is mirror-finished. In the case of plastic, it is possible to obtain higher heat insulation performance by wrapping aluminum foil.
