Description

本発明は、防音パネルおよび防音壁の改善に係り、より詳しくは、リサイクル性が高く、かつ軽量で、さらに低い周波数帯域から高い周波数帯域に亘って広範囲の周波数帯域の騒音を吸音することができる防音パネルおよび防音壁に関するものである。   The present invention relates to an improvement in a soundproof panel and a soundproof wall, and more specifically, is highly recyclable and lightweight, and can absorb noise in a wide frequency band from a low frequency band to a high frequency band. The present invention relates to a soundproof panel and a soundproof wall.

吸音構造体としては、従来からグラスウール等の多孔質吸音材と耐候性、耐水性、耐熱性に優れた材料を組み合わせた構造のものが用いられていた。ところが、このような吸音構造体では、グラスウールの耐候性、耐水性、耐熱性を補うことができたが十分ではなく、さらにリサイクル性の問題を解決するに至っていなかった。また、グラスウールに代表される多孔質吸音材を用いた場合以外の吸音構造である共鳴器型吸音構造や板振動型吸音構造等を利用した場合には、吸音のメカニズムの関係上、下記のような不具合があった。
即ち、吸音のメカニズムが共振現象によるエネルギー消散であるため、吸音周波数帯域が狭く、吸音性能がグラスウール等の多孔質吸音材等の多孔質吸音材に比べて劣るという不具合があった。 As a sound absorbing structure, a structure having a combination of a porous sound absorbing material such as glass wool and a material excellent in weather resistance, water resistance and heat resistance has been conventionally used. However, with such a sound absorbing structure, the weather resistance, water resistance, and heat resistance of glass wool could be compensated, but it was not sufficient, and the problem of recyclability was not solved. In addition, when using a resonator type sound absorbing structure or a plate vibration type sound absorbing structure that is a sound absorbing structure other than the case where a porous sound absorbing material typified by glass wool is used, due to the sound absorbing mechanism, There was a problem.
That is, since the sound absorption mechanism is energy dissipation due to a resonance phenomenon, the sound absorption frequency band is narrow, and the sound absorption performance is inferior to that of a porous sound absorbing material such as a porous sound absorbing material such as glass wool.

上記のような問題を解決し得るようにした吸音構造体としては、例えばアルミニウム箔や、アルミニウム薄板を用いた後述するような構成になるものが公知である。これら従来例１、２に係る吸音構造を、添付図面を参照しながら説明する。   As a sound-absorbing structure that can solve the above-mentioned problems, for example, a structure that will be described later using an aluminum foil or an aluminum thin plate is known. The sound absorbing structures according to the conventional examples 1 and 2 will be described with reference to the accompanying drawings.

従来例１に係る防音構造を、その斜視図の図１４と、その断面図の図１５を参照しながら説明する。即ち、この吸音構造は、例えばアルミニウム箔等の金属製の薄膜からなる第一の薄膜４１と、第二の薄膜４２とが互いに隣接するように積層されている。これら第一の薄膜４１と第二の薄膜４２には、図１５に示すように、これら第一の薄膜４１と第二の薄膜４２の積層方向の一側に向いた多数の突部ａが形成されている。そのため、この従来例１に係る防音構造によれば、音波が入射すると、第一、二の薄膜４１、４２が振動して、重なりあった部分が接触して擦れ合いを起こし、その結果、音波のエネルギー消散が生じて吸音される。   A soundproof structure according to Conventional Example 1 will be described with reference to FIG. 14 in a perspective view and FIG. 15 in a sectional view. That is, in this sound absorbing structure, the first thin film 41 made of a metal thin film such as an aluminum foil and the second thin film 42 are laminated so as to be adjacent to each other. As shown in FIG. 15, the first thin film 41 and the second thin film 42 are formed with a plurality of protrusions a facing one side in the stacking direction of the first thin film 41 and the second thin film 42. Has been. Therefore, according to the soundproof structure according to the conventional example 1, when sound waves are incident, the first and second thin films 41 and 42 vibrate and the overlapping portions come into contact with each other and rub against each other. The energy dissipation occurs and the sound is absorbed.

上記構成になる吸音構造では、上記のとおり、第一、二の薄膜４１、４２が接触して擦れ合うというメカニズムによって音波エネルギーを消散させるため、共振現象を利用して音波エネルギーを消散させる吸音構造に比較して、より広範囲の周波数帯域で優れた吸音性能を発揮することができる。また、第一、二の薄膜４１、４２の材料としてアルミニウム等の金属製箔を採用することにより、シュレッダーダスト等として処分せざるを得なかった従来に係る吸音構造のグラスウール等の難リサイクル材に比較して吸音構造のリサイクルが容易である。なお、第一、二の薄膜４１、４２には、多数の微細な貫通孔が設けられている（例えば、特許文献１参照。）。   In the sound absorbing structure configured as described above, as described above, the sound energy is dissipated by the mechanism in which the first and second thin films 41 and 42 come into contact with each other and rub against each other. In comparison, excellent sound absorption performance can be exhibited in a wider frequency band. Moreover, by adopting a metal foil such as aluminum as the material of the first and second thin films 41 and 42, it is difficult to recycle the conventional sound absorbing structure glass wool or the like that had to be disposed of as shredder dust or the like. In comparison, the sound absorbing structure can be easily recycled. The first and second thin films 41 and 42 are provided with a large number of fine through holes (see, for example, Patent Document 1).

次に、従来例２に係る防音構造を、その断面図の図１６を参照しながら同公報に用いられている同一の名称を以て説明する。即ち、この従来例２に係る防音構造は、外装板５１と多数の貫通穴５２ａを有する内装板５２とが対向配置されて構成されている。前記内装板５２は、板厚、穴径および開口率が貫通穴５２ａを流通する空気に粘性作用を発生させる、後述する設計条件を満足するように設定されている。この設定条件は、０．３以上の吸音率となる周波数帯域幅が共鳴周波数に対して１０％以上に設定されている。なお、符号５３は空気層である。   Next, the soundproof structure according to Conventional Example 2 will be described with the same name used in the publication with reference to FIG. That is, the soundproof structure according to the conventional example 2 is configured such that the exterior plate 51 and the interior plate 52 having a large number of through holes 52a are arranged to face each other. The interior plate 52 is set so that the plate thickness, the hole diameter, and the opening ratio satisfy a design condition to be described later that causes a viscous action to occur in the air flowing through the through hole 52a. In this setting condition, the frequency bandwidth that provides a sound absorption coefficient of 0.3 or more is set to 10% or more with respect to the resonance frequency. Reference numeral 53 denotes an air layer.

このような従来例２に係る防音構造によれば、空気に粘性作用を発生させることによって、粘性作用による空気振動の熱エネルギーへの変換が促進される結果、広い周波数帯域幅で十分な吸音性能が確実に発揮される。これにより、共鳴周波数の騒音の他、この周波数以外の騒音に対しても優れた吸音性能が発揮されることとなる。なお、この従来例２に係る防音構造の外装板５１および内装板５２は、鉄やアルミニウム等の金属や合成樹脂により形成されている（例えば、特許文献２参照。）。
特開２００４−２６４３７４号公報 特開２００３−５０５８６号公報 According to such a soundproof structure according to Conventional Example 2, by generating a viscous action in the air, the conversion of air vibrations due to the viscous action into thermal energy is promoted, resulting in sufficient sound absorption performance in a wide frequency bandwidth. Is surely demonstrated. Thereby, in addition to the noise at the resonance frequency, excellent sound absorbing performance is exhibited for noise other than this frequency. Note that the exterior plate 51 and the interior plate 52 having a soundproof structure according to the conventional example 2 are formed of a metal such as iron or aluminum or a synthetic resin (see, for example, Patent Document 2).

図１に示す符号１は、本発明の形態１に係る防音壁で、この防音壁１には後述する構成になる防音パネル２が１６枚使用されている。この防音パネル２は、図２乃至４に示すように、矩形状の後述するケース２ａと、このケース２ａ内に収納される、後述する吸音部材とからなるアルミニウム製のものである。前記ケース２ａは、矩形状の枠部２ｂを備え、この枠部２ｂの一側に背面板２ｃを備えると共に、他側の開口側が、音波が通過し得る複数の音波通過通路Ｐａを備えた着脱自在な０．８ｍｍ厚さの正面板２ｄにより覆われている。この場合、前記音波通過通路Ｐａは、直径が０．８ｍｍの貫通穴である。なお、この防音パネル２が防音壁フレームに取付けられ後、この防音パネル２の正面板２ｄの表面に、防音パネル２内に音波を通し、かつ防音パネル２内への雨の浸入を防止するためのガラリ１ａが取付けられる。   Reference numeral 1 shown in FIG. 1 is a soundproof wall according to the first embodiment of the present invention. The soundproof wall 1 uses 16 soundproof panels 2 configured as described later. As shown in FIGS. 2 to 4, the soundproof panel 2 is made of aluminum including a rectangular case 2a (described later) and a sound absorbing member (described later) housed in the case 2a. The case 2a includes a rectangular frame portion 2b, and includes a back plate 2c on one side of the frame portion 2b, and the other opening side includes a plurality of sound wave passages Pa through which sound waves can pass. It is covered with a free front plate 2d having a thickness of 0.8 mm. In this case, the sound wave passage Pa is a through hole having a diameter of 0.8 mm. In addition, after this soundproof panel 2 is attached to the soundproof wall frame, sound waves are passed through the surface of the front plate 2d of the soundproof panel 2 into the soundproof panel 2 and rain is prevented from entering the soundproof panel 2. The louver 1a is attached.

前記吸音部材は、前記ケース２ａの、図における上下方向の一方向に向く複数の円弧波形加工が施され、かつ図示しない多数の微細な貫通孔が設けられた縦円弧波形付アルミニウム薄板（縦波形付金属部材）２ｅと、この縦円弧波形付アルミニウム薄板２ｅの波形加工方向と直交する図における左右方向の他方向に向く複数の円弧波形加工が施され、かつ図示しない多数の微細な貫通孔が設けられた横円弧波形付アルミニウム薄板（縦波形付金属部材p２ｆとが交互に積層されてなる構成になっている。この場合、波形付アルミニウム薄板は３層構成になっているが、特に３層構成に限るものではなく、２層構成でも、４層構成でも良い。つまり、波形付アルミニウム薄板の層数は仕様によって決定されるべきものである。   The sound absorbing member is made of a thin aluminum plate with a vertical arc corrugation (longitudinal corrugation) in which a plurality of arc corrugations are applied to the case 2a in one direction in the vertical direction in the drawing and a plurality of fine through-holes not shown are provided. Attached metal member) 2e and a plurality of arc-shaped corrugations that are directed in other directions in the left-right direction in the drawing orthogonal to the corrugated direction of the aluminum thin plate 2e with corrugated longitudinal arc, and a large number of fine through-holes not shown. The provided aluminum thin plate with corrugated horizontal arcs (the metal members p2f with vertical corrugations are alternately laminated. In this case, the corrugated aluminum thin plate has a three-layer structure, and in particular, three layers. The number of layers of the corrugated aluminum thin plate should be determined according to the specification.

この形態１係る防音壁１に使用する防音パネル２においては、前記縦円弧波形付アルミニウム薄板２ｅと横円弧波形付アルミニウム薄板２ｆは、何れも０．１〜０．３ｍｍ厚さのものである。これら縦円弧波形付アルミニウム薄板２ｅ、横円弧波形付アルミニウム薄板２ｆは、アルミニウム薄板に、例えばロール圧延により直径０．１ｍｍ程度の多数の微細な貫通孔を明けた後、例えばプレス成形により高さ寸法が２０ｍｍの円弧波状加工を施して製作されたものである。なお、このような防音パネル２は工場で製造され、そして現地に搬送されて防音壁フレームに取付けられるものである。   In the soundproof panel 2 used for the soundproof wall 1 according to the first embodiment, the aluminum thin plate 2e with the vertical arc corrugation and the aluminum thin plate 2f with the horizontal arc corrugation are both 0.1 to 0.3 mm thick. The aluminum thin plate 2e with a vertical arc corrugation and the aluminum thin plate 2f with a horizontal arc corrugation have a height dimension by, for example, press molding after drilling a large number of fine through holes having a diameter of about 0.1 mm by roll rolling, for example. Is produced by applying a 20 mm circular arc-shaped process. Such a soundproof panel 2 is manufactured at a factory and is transported to the site and attached to a soundproof frame.

以下に、本発明の形態１に係る防音壁１、または防音パネル２の作用態様を説明する。
即ち、吸音部材である縦円弧波形付アルミニウム薄板２ｅの円弧波形と、横円弧波形付アルミニウム薄板２ｆの円弧波形との間に空気層が形成されるため、音波の共鳴現象が起こり、これら波形付アルミニウム薄板にあけられた多数の微細な貫通孔部で激しく振動する空気の粘性作用によって音波エネルギーが消散する。従って、本発明の形態１に係る防音壁１、または防音パネル２によれば、従来例の場合と同様に、共振現象のみを利用して音波エネルギーを消散させる吸音構造に比較して、より広範囲の周波数帯域で優れた吸音性能を発揮することができる。 Hereinafter, the operation mode of the soundproof wall 1 or the soundproof panel 2 according to the first embodiment of the present invention will be described.
That is, since an air layer is formed between the circular arc waveform of the aluminum thin plate 2e with longitudinal arc waveform and the circular arc waveform of the aluminum thin plate 2f with horizontal arc waveform, which is a sound absorbing member, a sound wave resonance phenomenon occurs, The sound energy is dissipated by the viscous action of air that vibrates vigorously in a large number of fine through-holes formed in an aluminum thin plate. Therefore, according to the soundproof wall 1 or the soundproof panel 2 according to the first embodiment of the present invention, as in the case of the conventional example, compared with the sound absorbing structure that dissipates the sound wave energy using only the resonance phenomenon, it is more extensive. Excellent sound absorption performance can be exhibited in the frequency band of.

また、本発明の形態１に係る防音壁１または防音パネル２によれば、吸音材がアルミニウム薄板を使用しているから、従来例１または２に係る防音構造と同様に、シュレッダーダスト等として処分せざるを得なかった吸音構造のグラスウール等の難リサイクル材に比較してリサイクルが容易である。   Further, according to the soundproof wall 1 or the soundproof panel 2 according to the first embodiment of the present invention, since the sound absorbing material uses an aluminum thin plate, it is disposed as a shredder dust or the like as in the soundproof structure according to the conventional example 1 or 2. Recycling is easier compared to difficult-to-recycle materials such as glass wool with a sound-absorbing structure that had to be done.

本発明の形態２に係る防音壁に使用する防音パネルを、添付図面を参照しながら説明する。図５は、円弧状波形加工された円弧状傾斜波形付アルミニウム薄板の組立状態説明斜視図である。なお、この防音パネルを使用する形態２に係る防音壁の全体構成は、上記形態１に係る防音壁と同形状であるから、防音壁の構成に係る説明は割愛する。   The soundproof panel used for the soundproof wall according to the second embodiment of the present invention will be described with reference to the attached drawings. FIG. 5 is a perspective view illustrating an assembled state of the aluminum thin plate with an arcuate inclined waveform processed by the arcuate corrugation. In addition, since the whole structure of the soundproof wall which concerns on the form 2 which uses this soundproof panel is the same shape as the soundproof wall which concerns on the said form 1, the description which concerns on the structure of a soundproof wall is omitted.

即ち、この形態２に係る防音パネルの吸音部材は、斜め方向に向く複数の傾斜円弧波形加工が施され、かつ多数の微細な貫通孔が設けられた傾斜円弧波形付アルミニウム薄板２ｇが、隣り合う傾斜円弧波形付アルミニウム薄板２ｇの傾斜円弧波形が交差するように交互に積層されて、図示しないケース内に収納されている。この傾斜円弧波形付アルミニウム薄板２ｇの多数の微細な貫通孔の直径や円弧波形の高さ寸法は、上記形態１の場合と同様の値に設定されている。   That is, the sound absorbing member of the soundproof panel according to the second embodiment is adjacent to the aluminum thin plate 2g with an inclined arc corrugation that has been subjected to a plurality of inclined arc corrugations that are directed in an oblique direction and provided with a number of fine through holes. The aluminum thin plates 2g with inclined arc waveforms are alternately stacked so that the inclined arc waveforms intersect with each other, and are stored in a case (not shown). The diameters of a large number of fine through holes and the height dimension of the arc corrugation of the aluminum thin plate with inclined arc corrugation 2g are set to the same values as in the first embodiment.

本発明の形態２に係る防音壁に使用する防音パネルによれば、アルミニウム薄板に加工されている円弧波形が傾斜している点が上記形態１に係る防音壁に使用する防音パネルと相違しているだけである。従って、本発明の形態２に係る防音壁に使用する防音パネルは、上記形態１に係る防音壁に使用する防音パネルと同効である。   According to the soundproofing panel used for the soundproofing wall according to the second embodiment of the present invention, the arcuate waveform processed into the aluminum thin plate is inclined, unlike the soundproofing panel used for the soundproofing wall according to the first embodiment. There is only. Therefore, the soundproof panel used for the soundproof wall according to the second embodiment of the present invention is the same as the soundproof panel used for the soundproof wall according to the first embodiment.

以上の形態１，２に係る防音パネルの場合、重なり合う円弧状波形付アルミニウム薄板の円弧波形同士は交差して先端同士が接触しているが、重なり合う円弧状波形付アルミニウム薄板の円弧波形同士は交差していなくても良い。例えば、本発明の形態３に係る防音パネルは、後述するように構成されている。即ち、図示省略しているが、重なり合う円弧状波形付アルミニウム薄板の円弧波形同士は同一方向を向いており、そして円弧波形の先端同士が接触するように構成されている。従って、円弧波形の間に空気層が形成されるため、音波の共鳴現象が起こり、これらの波形付アルミニウム薄板にあけられた多数の微細な貫通孔部で激しく振動する空気の粘性作用によって音波エネルギーが消散するから、このような構成によっても、上記形態１，２に係る防音パネルと同等の効果を得ることができる。 For acoustic panel according to Embodiment 1 of the following, but leading ends arc waveform each other intersects the overlapping arcuate waveform with aluminum sheet is in contact, an arc waveform between the overlapping arcuate waveform with aluminum lamellae It does not have to intersect. For example, the soundproof panel according to Embodiment 3 of the present invention is configured as described later. That is, although not shown in the drawings, the arcuate waveforms of the overlapping arcuate corrugated aluminum thin plates face the same direction, and the tips of the arcuate waveforms are configured to contact each other. Therefore, since an air layer is formed between the arcuate waveforms, a sound wave resonance phenomenon occurs, and the sonic energy is generated by the viscous action of air that vibrates vigorously in a large number of fine through holes formed in these corrugated aluminum thin plates. Therefore, even with such a configuration, an effect equivalent to that of the soundproof panel according to the first and second embodiments can be obtained.

本発明の形態４に係る防音壁に使用する防音パネルを、添付図面を参照しながら説明する。図６は本発明の形態３に係る防音壁に使用する防音パネルの模式的正面図、図７は図６のＣ−Ｃ線断面図、図８は図６のＤ−Ｄ線断面図である。   A soundproof panel used for a soundproof wall according to Embodiment 4 of the present invention will be described with reference to the accompanying drawings. 6 is a schematic front view of a soundproof panel used for a soundproof wall according to Embodiment 3 of the present invention, FIG. 7 is a cross-sectional view taken along line CC in FIG. 6, and FIG. 8 is a cross-sectional view taken along line DD in FIG. .

本発明の形態４に係る防音壁に使用する防音パネル３は、図６乃至８に示すように、上記形態１に係るケースと同構成になるケース３ａと、このケース３ａ内に収納される後述する吸音部材とから構成されている。前記吸音部材は、前記ケース３ａの、図における上下方向の一方向に向く複数の縦円弧波形加工が施され、かつ図示しない多数の微細な貫通孔が設けられた縦円弧波形付アルミニウム薄板３ｅと、多数の微細な貫通孔が設けられたアルミニウム薄板３ｆとが交互に積層されてなる構成になっている。   As shown in FIGS. 6 to 8, the soundproof panel 3 used for the soundproof wall according to the fourth embodiment of the present invention has a case 3a having the same configuration as the case according to the first embodiment, and will be described later. Sound absorbing member. The sound absorbing member includes a longitudinal arc corrugated aluminum thin plate 3e which is provided with a plurality of longitudinal arc corrugations that are directed in one direction in the vertical direction in the drawing of the case 3a and in which a number of fine through holes (not shown) are provided. The aluminum thin plates 3f provided with a large number of fine through holes are alternately stacked.

この形態４に係る防音壁に使用する防音パネル３の縦円弧波形付アルミニウム薄板３ｅは、０．１〜０．３ｍｍ厚さのアルミニウム薄板に、例えばロール圧延により直径０．１ｍｍ程度の多数の微細な貫通孔を明けた後、例えばプレス成形により高さ寸法が２０ｍｍの縦円弧波形加工を施したものであり、上記形態１の場合と同様である。なお、この形態３に係る防音壁に使用する防音パネル３においては縦円弧波形付アルミニウム薄板３ｅを採用しているが、上記形態１に係る防音壁に使用する防音パネルに用いた横円弧波形付アルミニウム薄板に置換することができる。   The aluminum thin plate 3e with a vertical arc corrugation of the soundproof panel 3 used for the soundproof wall according to this embodiment 4 is made of a large number of fine pieces having a diameter of about 0.1 mm by roll rolling, for example, on an aluminum thin plate having a thickness of 0.1 to 0.3 mm. After forming a through hole, vertical arc corrugation with a height dimension of 20 mm is performed, for example, by press molding, which is the same as in the case of the first embodiment. In addition, in the soundproof panel 3 used for the soundproof wall according to the third embodiment, the aluminum thin plate 3e with the vertical arc corrugation is adopted, but with the horizontal arc corrugated used for the soundproof panel used for the soundproof wall according to the first embodiment. It can be replaced with an aluminum sheet.

ところで、アルミニウム薄板が極めて薄く、５００ｍｍ×２０００ｍｍ程度の寸法になるとその剛性の関係上、ケースに組込むことが困難な場合には、アルミニウム薄板を後述するような構成になる枠体に取付け、アルミニウム薄板を取付けた枠をケースに組込む構成にすることができる。その場合、ケースの上下構成部品にガイドレールを有するアルミニウム押出し部材を用い、引き戸のようにガイドレールに沿ってスライドさせて押込んだ後、長手方向の一方のサイドの縦部材を固着して矩形状にすることにより、防音パネルが構成されることとなる。   By the way, if the aluminum thin plate is extremely thin and has a dimension of about 500 mm × 2000 mm, if it is difficult to incorporate it into the case due to its rigidity, the aluminum thin plate is attached to a frame body configured as described later. It is possible to adopt a configuration in which the frame with the attached is incorporated into the case. In that case, aluminum extruded members with guide rails are used for the upper and lower components of the case, and after sliding and sliding along the guide rails like a sliding door, the longitudinal member on one side in the longitudinal direction is fixed and rectangular. A soundproof panel will be comprised by setting it as a shape.

即ち、障子枠状の貼着枠に両面テープを用いてアルミニウム薄板を貼着し、このアルミニウム薄板を貼着した貼着枠をケースに組込んでも良い。また、チャンネル状のアルミニウム部材を、開口側を相対する側に向けた矩形状のアルミニウム薄板取付枠を作成し、このアルミニウム薄板取付枠の溝に、アルミニウム薄板の端部が嵌込まれた、断面角状のゴム紐を嵌め込んでアルミニウム薄板を張力を付与した状態で取付け、アルミニウム薄板を取付けたアルミニウム薄板取付枠をケースに組込んでも良い。また、矩形状のアルミニウム薄板取付け枠を作成し、このアルミニウム薄板取付け枠にアルミニウム薄板を巻き付けて無端状にした後、アルミニウム薄板を巻き付けたアルミニウム薄板取付け枠をケースに組込んでも良い。さらに、アルミニウム薄板取付枠の枠部材の側面に溝を設け、ゴム紐をアルミニウム薄板の上側から溝に押し込んで、所謂網戸の網のように、アルミニウム薄板をアルミニウム薄板取付枠に取付け、アルミニウム薄板を取付けたアルミニウム薄板取付枠をケースに組込んでも良い。   That is, an aluminum thin plate may be stuck to a shoji frame-like sticking frame using a double-sided tape, and the sticking frame on which the aluminum thin plate is stuck may be incorporated into the case. In addition, a cross section in which a channel-shaped aluminum member is formed into a rectangular aluminum thin plate mounting frame with the opening side facing the opposite side, and the end of the aluminum thin plate is fitted in the groove of the aluminum thin plate mounting frame An aluminum thin plate may be attached in a state where a square rubber string is fitted and tension is applied, and an aluminum thin plate mounting frame to which the aluminum thin plate is attached may be incorporated in the case. Alternatively, a rectangular aluminum thin plate mounting frame may be prepared, and the aluminum thin plate may be wound around the aluminum thin plate mounting frame to make it endless, and then the aluminum thin plate mounting frame wound with the aluminum thin plate may be incorporated into the case. Furthermore, a groove is provided on the side surface of the frame member of the aluminum thin plate mounting frame, and the rubber cord is pushed into the groove from the upper side of the aluminum thin plate, and the aluminum thin plate is attached to the aluminum thin plate mounting frame like a so-called screen door net. The attached aluminum thin plate mounting frame may be incorporated in the case.

本発明の形態４に係る防音壁に用いる防音パネル３によれば、上記形態１に係る防音壁に用いる防音パネルの場合と同様に、縦円弧波形付アルミニウム薄板３ｅの円弧波形と、アルミニウム薄板３ｆの平面部との間に空気層が形成されるため、音波の共鳴現象が起こり、これら波形付アルミニウム薄板にあけられた多数の微細な貫通孔部で激しく振動する空気の粘性作用によって音波エネルギーが消散する。従って、従来例１の場合と同様に、共振現象のみを用いて音波エネルギーを消散させる吸音構造に比較して、より広範囲の周波数帯域で優れた吸音性能を発揮することができるから、上記形態１に係る防音壁に用いる防音パネルと同効である。   According to the soundproof panel 3 used for the soundproof wall according to the fourth embodiment of the present invention, as in the case of the soundproof panel used for the soundproof wall according to the first embodiment, the arc waveform of the aluminum thin plate 3e with the vertical arc waveform and the aluminum thin plate 3f. An air layer is formed between the flat surface and the acoustic wave resonance phenomenon occurs, and the sound wave energy is generated by the viscous action of air that vibrates vigorously in a number of fine through-holes formed in these corrugated aluminum thin plates. Dissipate. Therefore, as in the case of the conventional example 1, it is possible to exhibit an excellent sound absorbing performance in a wider frequency band than the sound absorbing structure that dissipates the sound wave energy using only the resonance phenomenon. This is the same effect as the soundproof panel used for the soundproof wall according to the above.

本発明の形態５に係る防音壁に用いる防音パネルを説明する。なお、この防音パネルを使用する防音壁の全体構成は、上記形態１に係る防音壁と同形状であるから、防音壁に係る説明は割愛する。   The soundproof panel used for the soundproof wall according to the fifth embodiment of the present invention will be described. In addition, since the whole structure of the soundproof wall which uses this soundproof panel is the same shape as the soundproof wall which concerns on the said form 1, the description which concerns on a soundproof wall is omitted.

この形態５に係る防音壁に用いる防音パネルの吸音部材は、後述する２種類の円弧波形付アルミニウム薄板が交互に積層されて構成されている。即ち、一方の第１円弧波形付アルミニウム薄板の４個所の周縁部には、外方向向きに複数の円弧波形加工が施されており、それ以外の中央部分は平面になっている。そして、これら円弧波形加工領域、および平面領域に多数の微細な貫通孔が設けられている。また、前記第１円弧波形付アルミニウム薄板に積層される他方の第２円弧波形付アルミニウム薄板は、この第１円弧波形付アルミニウム薄板の平面領域に先端部が接触する複数の円弧波形加工が施されおり、それ以外の４個所の周縁部は平面になっている。そして、これら円弧波形加工領域、および平面領域に多数の微細な貫通孔が設けられている。   The sound absorbing member of the soundproof panel used for the soundproof wall according to the fifth aspect is configured by alternately laminating two types of aluminum thin plates with arc corrugations described later. That is, a plurality of arc corrugations are applied outwardly at the four peripheral portions of one first arc corrugated aluminum thin plate, and the other central portion is flat. And many fine through-holes are provided in these circular-arc waveform processing area | regions and plane area | regions. In addition, the other second arcuate corrugated aluminum sheet laminated on the first arcuate corrugated aluminum sheet is subjected to a plurality of arcuate corrugations in which the tip portion contacts the flat area of the first arcuate corrugated aluminum sheet. The other four peripheral portions are flat. And many fine through-holes are provided in these circular-arc waveform processing area | regions and plane area | regions.

本発明の形態５に係る防音壁に用いる防音パネルでは、一方の第１円弧波形付アルミニウム薄板の円弧波形と他方の第２円弧波形付アルミニウム薄板の平面部との間に空気層が形成されると共に、他方の第２円弧波形付アルミニウム薄板の円弧波形と一方の第１円弧波形付アルミニウム薄板の平面部との間に空気形成される。従って、本発明の形態４に係る防音壁に用いる防音パネルによれば、円弧波形と平面部との間に空気層が形成されるため、音波の共鳴現象が起こり、これら波形付アルミニウム薄板にあけられた多数の微細な貫通孔部で激しく振動する空気の粘性作用によって音波エネルギーが消散するから、本実施の形態４は上記形態１と同効である。   In the soundproof panel used for the soundproof wall according to the fifth aspect of the present invention, an air layer is formed between the arcuate waveform of one aluminum thin plate with the first arc corrugation and the flat portion of the other aluminum thin plate with the second arcuate corrugation. At the same time, air is formed between the arcuate waveform of the other aluminum sheet with the second arcuate corrugation and the flat portion of the aluminum sheet with the first arcuate corrugation. Therefore, according to the soundproof panel used for the soundproof wall according to the fourth embodiment of the present invention, an air layer is formed between the arcuate waveform and the flat surface portion, so that a sound wave resonance phenomenon occurs, and the corrugated aluminum thin plate is opened. Since the sound wave energy is dissipated by the viscous action of air that vibrates vigorously in a large number of fine through-hole portions, the fourth embodiment has the same effect as the first embodiment.

本発明の形態１乃至５に係る防音パネルの吸音部材は円弧波形付アルミニウム薄板から構成されているが、箔であっても良く、表面に繊維が貼着されてなる板であっても良く、表面に繊維が貼着されてなる箔であっても良い。   The sound absorbing member of the soundproof panel according to Embodiments 1 to 5 of the present invention is composed of an aluminum thin plate with an arc corrugation, but may be a foil or a plate in which fibers are attached to the surface, It may be a foil in which fibers are attached to the surface.

ところで、以上の実施の形態１乃至５に係る防音パネルの場合にあっては、高速道路の防音壁に用いる防音パネルの吸音部材であるアルミニウム薄板に加工する波形が円弧波形である場合を例として説明した。しかしながら、アルミニウム薄板に加工する波形は、特に円弧波形に限定されるものではない。例えば、アルミニウム薄板に四角波形加工が施されていても良く、台形波形加工が施されていても良く、また三角波形加工が施されていても良く、何れの波形であっても同等の機能を発揮することができる。   By the way, in the case of the sound insulation panel which concerns on the above Embodiment 1 thru | or 5, the case where the waveform processed into the aluminum thin plate which is a sound-absorbing member of the sound insulation panel used for the sound insulation wall of a highway is an arc waveform is an example. explained. However, the waveform processed into the aluminum thin plate is not particularly limited to the arc waveform. For example, an aluminum thin plate may be subjected to square waveform processing, trapezoidal waveform processing, or triangular waveform processing, and the same function can be achieved with any waveform. It can be demonstrated.

以下、本発明の形態７に係る防音壁に使用する防音パネル６の作用態様について説明する。即ち、この防音パネル６によれば、従来例２に係る防音構造と同様に、空気に粘性作用を発生させることによって、粘性作用による空気振動の熱エネルギーへの変換が促進される結果、広い周波数帯域幅で十分な吸音性能が確実に発揮される。これにより、共鳴周波数の騒音の他、この周波数以外の騒音に対しても優れた吸音性能が発揮されるから、上記形態１の防音壁に使用する防音パネルと同効である。   Hereinafter, the operation mode of the soundproof panel 6 used for the soundproof wall according to the seventh embodiment of the present invention will be described. That is, according to the soundproof panel 6, as in the soundproof structure according to the conventional example 2, by generating a viscous action on the air, the conversion of the air vibration by the viscous action into thermal energy is promoted, resulting in a wide frequency range. Sufficient sound absorption performance is reliably demonstrated in the bandwidth. Thereby, in addition to the noise of the resonance frequency, excellent sound absorbing performance is exhibited for noise other than this frequency, and therefore, it is effective as the soundproof panel used for the soundproof wall of the first aspect.

より詳しくは、防音対象となる音の波長の１／２より小さな間隔で仕切り板を設けることにより、この防音パネル内に侵入した音波を吸音部材と直交する方向に進行させることができるため防音パネルの吸音効果が向上する。また、防音対象となる音の波長の１／２の倍数以外の間隔で仕切り板を設けることにより、防音パネル内に侵入した音波の吸音部材に沿う方向への進行を防ぎ、吸音部材と直交する方向に進行させることができるため防音パネルの吸音効果が向上する。さらに、防音対象となる複数の周波数の音に対してランダムな間隔で仕切り板を設けることにより、防音パネル内に侵入した特定周波数の音波の吸音性能の低下を防止することができるため、複数の周波数の音に対する防音パネルの吸音効果が向上する。従って、上記構成になる３種類の防音パネルのうちの何れかを、防音壁フレームの複数のパネル取付け枠のそれぞれに嵌込んで防音壁を構成することにより防音性能がより優れた防音壁を具現することができる。   More specifically, by providing a partition plate with an interval smaller than ½ of the wavelength of the sound to be soundproofed, sound waves that have entered the soundproof panel can be advanced in a direction perpendicular to the sound absorbing member, so that the soundproof panel The sound absorption effect is improved. In addition, by providing partition plates at intervals other than a multiple of 1/2 of the wavelength of the sound to be sound-proofed, the sound waves that have entered the sound-proof panel are prevented from traveling in the direction along the sound-absorbing member, and are orthogonal to the sound-absorbing member.
