DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in soundproofing materials used in the technical field of construction and construction.

[0002]

2. Description of the Related Art The sensation for sound occurs when the sound stimulates a listener (hearing organ). The audible range of the sound in the case of a human is a frequency of 20 Hz to 20 kHz, and it is said that the sensitivity to 1 kHz to 5 kHz is the highest.

[0003] Most of the noise generated in a residential area is airborne sound, solid-borne sound, or a composite sound of these. Such noise sources are ubiquitous, both indoors and outdoors. Defining noise is
This is difficult because there are individual differences and the sensitivity varies depending on the place and time zone. However, noise standards are specified by region and time in the Noise Control Law, so this is helpful. By the way, in the case of a residential area, 40-5
Anything over 0 phones is considered noise. Of particular concern in urban residential areas is traffic noise, which often exceeds 50 phones.

[0004] At present, with respect to traffic noises on highways and railways, by providing facilities with a high soundproofing effect, the results have been reduced. On the other hand, in the case of traffic noise emitted from general roads, the road administration is behind or the control of noise-violating vehicles is insufficient,
Self-defense measures have to be taken.

[0005]

In a case where noise generated from an outdoor sound source is prevented from propagating indoors,
It is desirable to cut off this halfway. From this point of view, fences and fences are also useful for soundproofing. However, fences are more soundproof than fences, but have the drawbacks of lack of ventilation, poor visibility, and a great deal of oppression and blockage. Conversely, fences have the drawback of being very low in soundproofing but good in ventilation and visibility.

On the other hand, as for soundproof walls for blocking sound, it is said that a heavy and solid sound insulating material is effective for airborne sound, and a sound absorbing material is also effective for lowering the noise level. It is said that there is. In other words, many soundproofing walls have been developed based on these considerations. However, the high cost of existing sound barriers has been a major bottleneck, and has not yet become widely used.

SUMMARY OF THE INVENTION [0007] In view of the above technical problems, the present invention provides a high level of soundproofing, air permeability, high strength, light weight,
It is an object of the present invention to provide a soundproofing material for building construction which can satisfy these requirements, such as low price, versatility, simplicity of construction, and removal of harmful substances.

Respectively showing a number of small through holes.

The corrugated plate 11 is typically made of a plastic molded product (a variety of synthetic resin molded products including FRP molded products). As another example, the corrugated plate 11 may be made of a metal processed product or a wooden product / concrete molded product (including a steel bar). Other examples include plastic, metal, tempered glass, wood, concrete, etc.
The corrugated plate 11 may be composed of two or more of these composite materials. Among the corrugated plates 11 made of these materials, the corrugated plate 1 made of a flexible or flexible material
1. For example, the flexible plastic corrugated plate 11 can be contracted or expanded like an accordion type curtain by utilizing the elasticity based on the material and the bent shape.

The convex portions 12 and the concave portions 13 of the corrugated plate 11 are arranged alternately and continuously. In addition,
When viewed from the surface (outer surface) of the corrugated plate 11,
When viewed from the back surface (inner surface), the convex portion 12 and the concave portion 13 are reversed. This means that the convex portion 12 and the concave portion 13 have a front-back integrated relationship.

The many small irregularities 14 on the corrugated plate 11 are formed, for example, by providing a large number of small protrusions on the surface of the corrugated plate 11 adjacent to each other. In the illustrated example, the uneven shape 14 is an uneven shape in which each of the triangular small protrusions is adjacent. For this, a rounded uneven shape, an uneven shape such as a square,
Some have satin patterns. Such uneven shape 14
Is formed on the entire surface (outer surface) of the corrugated plate 11 as shown in the illustrated example, is formed on the entire back surface (inner surface) of the corrugated plate 11, or is formed on the entire front and back surfaces (both inner and outer surfaces) of the corrugated plate 11.

When the soundproofing material for building construction illustrated in FIG. 1 is used as a lining material (non-bearing wall) of a building wall, an example is shown in FIG.

Fixing fittings 22 are mounted at appropriate places on the inner surface of the building wall 21 shown in FIG. The corrugated plate 11 has a tip end of the convex portion 12 applied to the fixing bracket 22, and is then screwed over a part of the corrugated plate 11 and the fixing bracket 22. It is attached to the inner surface of the building wall 21 via the agent. In this case, a fastener 23 such as a screw or a nail may be partially used.
On the other hand, each of the corrugated plates 11 adjacent to each other is provided with a connecting member 24 made of metal or synthetic resin between the adjacent portions, and then a well-known stop extending between a predetermined portion of the corrugated plates 11 and the connecting member 24. The corrugated plates are connected to each other via a tool or an adhesive. In this example, a predetermined number of spaces 25 are formed between the inner surface of the building wall 21 and each of the concave portions 13 of the corrugated plate 11. One or more (including all) of the spaces 25 may be filled with a filtering material and / or an adsorbing material to form a filler layer 26. Filtering material and adsorbent for forming the filler layer 26 are:
It is known or known. These include zeolite, activated carbon, activated alumina, silica gel, titanium oxide, filter paper, felt, glass fiber layer,
Various porous bodies are used alone or in any combination. Therefore, the filler layer 26 may be a filter material alone or an adsorbent material alone.
When the filter material and the adsorbent for the filler layer are smaller than the through-hole 15, they are stored in a breathable bag such as a cloth bag or a mesh bag and packed in the space 25. This is a consideration for preventing a filtering material, a filler material, and the like from spilling out of the through hole 15.

A building wall 21 having such a lining structure
In the case of, the convex portion 12 and the concave portion 1 of the corrugated plate 11 having the inclined surface
Since the sound colliding with 3 is scattered by the inclined surface and the uneven shape 14, the volume of a specific direction or a specific portion does not increase. Also, the sound that has entered the space 25 through the through hole 15 of the corrugated plate 11 is attenuated while the reflection is repeated here. Therefore, the sound generated in the space surrounded by the building wall 21 is suppressed from becoming noise.
In addition, the air entering and exiting the space 25 is filtered or adsorbed by the filler layer 26 in the space 25 to remove harmful substances and impurities therein, so that the air having a high degree of cleanliness is obtained.

In FIG. 3, it is optional to form two or more rows of corrugated plates 11. In addition, the corrugated plates 11 are arranged such that the ridges 12 and the concaves 13 are arranged along the vertical direction,
Arranging the corrugated plates 11 such that the ridges 12 and the recesses 13 are arranged along the horizontal direction is also an arbitrary matter in FIG.

The lining structure illustrated in FIG. 3 can also be applied to the ceiling of a building. The ceiling of the building thus configured also exhibits the same soundproofing function and air purifying function as described above.

FIGS. 4 and 5 show an example in which a fence or fence is formed using the soundproofing material for building construction of FIG.

In FIG. 4, the lower (ground) sound insulating material row has a number of corrugated plates 11 arranged in an upright state, and the upper sound insulating material row also has a large number of corrugated plates 11 arranged in an upright state. Is what it is. Each of the lower and upper soundproofing materials (corrugated plate 1)
1) is to connect with each other using the columns 27 built at intervals corresponding to the width of the corrugated plate. Specifically, since each column 27 has a V-shaped cross section as shown in FIG. 5, each corrugated plate 11 has its left side and right side applied to each column 27 and then has bolts, nuts or It is fixed to each column 27 with a well-known fastener such as a rivet. The column 27 is made of metal, wood or concrete wood.

The fence or fence constructed in this way is
When external noise collides with the corrugated plate 11, most of the noise is irregularly reflected, and only a part of the noise is transmitted through each through hole 15. Therefore, the propagation of external noise to the inside of the boundary where the soundproofing material is built is greatly suppressed. Conversely, the propagation of internal noise to the outside is also greatly suppressed. In addition, since each through-hole 15 imparts ventilation to the fence or fence and eases the feeling of blockage,
These points are also desirable compared to the completely blindfold type.

When the fence or fence shown in FIG. 4 is constructed, the soundproofing material row may be formed in only one step or two or more steps, and the convex portions 12 and the concave portions 13 of the corrugated plate 11 may be in the horizontal direction. Each soundproofing material may be arranged so as to follow.

Next, another embodiment of the soundproofing material for building construction according to the present invention will be described with reference to FIG.

It is configured by connecting. The connecting member 24 for the V-shaped member is as described above. The connecting member 24 is used in the same manner as described above, and one of the V-shaped members 11a is connected and the other of the V-shaped members 11b is connected. The two corrugated plates 11A and 11B are also coupled such that these convex portions 12 and concave portions 13 face each other. The connecting member 28 made of metal or synthetic resin used in this case is a corrugated plate 11A.
Each V-shaped member 11a on the side and each V-shaped member 1 on the corrugated plate 11B side
1b are applied to the inner surface or the outer surface of the abutted portion, respectively, and then both corrugated plates 11A and 11B are connected to the predetermined portions of the V-shaped members 11a and 11b and the connecting member 28 through well-known fasteners or adhesives. Are combined. The thus constructed sound insulation material for building construction of FIG. 6 has a predetermined number of spaces 29 formed between both corrugated plates 11A and 11B. One or more (including all) of these spaces 29 may be filled with the above-described filtering material and / or adsorbing material to form the filler layer 26. When each of the V-shaped members 11a and 11b is made of a flexible or flexible material, the soundproofing material for building construction shown in FIG. 6 has the same elasticity as described above.

In the soundproofing material for building construction shown in FIG. 6, the upper surface and / or the lower surface may be closed by a lid attached to these surfaces. Also, each through hole 15 on the corrugated plate 11A side and each through hole 15 on the corrugated plate 11B side

FIGS. 7 and 8 show an example in which a fence or a fence is formed using the soundproofing material for building construction of FIG.

In FIG. 7, the lower (ground) sound insulating material row and the upper sound insulating material row above the same are both connected in parallel with the combined body (many) of both corrugated plates 11A and 11B in an upright state. Is what it is. These lower and upper soundproofing materials are connected to each other using the columns 30 that are built at intervals corresponding to the width of the corrugated plate. Specifically, each support 30
Has an X-shaped cross section as shown in FIG. 8, so that each soundproofing material (combined body of both corrugated plates 11A and 11B)
After the right side is applied to each column 30, it is fixed to each column 30 with the above-mentioned well-known stopper. Other, X-shaped support 30
On the front and / or back side of the cover plate 3 having many holes
1 is attached. The material of this lid plate 31 is
It is the same as that of 1A and 11B.

The fence or fence constructed in this way also has
Since most of the noise from the outside collides with the corrugated plate 11A, the noise is irregularly reflected, so that the propagation of the external noise to the inside of the boundary where the soundproofing material is installed is greatly suppressed. Conversely, the propagation of internal noise to the outside is also greatly suppressed. In such a fence or fence, the filler layer 2
When the space 6 is not in the space 29, the through holes 15 allow the wall or the fence to have air permeability or reduce the feeling of blockage. When the filler layer 26 is in the space 29,

In addition, the front and / or the back surface of the soundproofing material can be freely painted or covered.

[0040]

The soundproofing material for building construction according to the present invention has the following effects.

[Effect 1: Soundproofing] The noise colliding with the corrugated plate is reflected and scattered by the convex portions and the concave portions, and further scattered by small irregularities. Therefore, the sound volume in a specific direction or a specific portion does not increase, and the high soundproofing property is exhibited as a noise blocking material.

[Effect 2: Air permeability] Since a large number of through holes scattered on the surface of the corrugated plate impart air permeability to the soundproofing material,
There is no sacrifice in ventilation for soundproofing. In addition, since each through hole is provided, the feeling of blockage due to the soundproofing material is reduced.

[Effect 3: High Strength and Light Weight] The soundproofing material mainly composed of a corrugated plate is a continuous body of convex portions and concave portions. This has a greater apparent volume than a flat plate, but is lighter. In addition, the strength of the soundproofing material is high because the convex and concave portions make it difficult for the corrugated plate to buckle. Therefore, vertical and horizontal structures for construction made of this lightweight, high-strength soundproofing material are also effective in terms of earthquake countermeasures, and even if they break, they may damage people and things. Make it trivial.

[Effect 4: Low Price] As described above, the soundproofing material is lightweight, bulky, and strong, but is inexpensive because it is mainly made of a corrugated plate.

[Effect 5: Simplicity of Construction and Versatility] This soundproofing material is a general-purpose material that can be used for fences, fences, inner and outer walls of buildings, ceilings, lining materials, outer lining materials, and various other types. There is. This soundproofing material also has a simple construction since a desired structure can be formed by a less difficult operation such as erection, connection, and attachment.

[Effect 6: Removal of Harmful Substances] When the soundproofing material is mainly composed of two corrugated plates and a filler layer having a ventilation gap is formed in the space between the corrugated plates. Can remove harmful substances in the air through the filler layer. In particular, when the filler layer is made of a filtering material and / or an adsorbing material, the effect of removing harmful substances becomes higher.
