1299853 (1) 九、發明說明 【發明所屬之技術領域】 本發明是關於隔音板及隔音牆的改良技術，更詳言之 - 是關於回收性高，且重量輕，而且可吸收低頻率帶域到高 ★ 頻率帶域的廣範圍頻率帶域之噪音的隔音板。 【先前技術】 Φ 就吸音構造體而言，以往是使用將玻璃棉等的多孔質 吸音材以及耐候性、耐水性、耐熱性佳的材料加以組合的 構造。然而，這種吸音構造體雖可補足玻璃棉的耐候性、 耐水性、耐熱性，但卻並不充分，而且並未解決回收性的 問題。此外，在利用使用了以玻璃棉爲代表的多孔質吸音 材之情況以外的吸音構造，即共鳴器型吸音構造或板振動 型吸音構造等的情況下，由於吸音構造的關係，產生了如 下的問題。亦即，吸音構造是利用共振現象進行能量消散 ，因此產生了吸音頻率帶域狹窄，且吸音性能比玻璃棉等 ^ 之多孔質吸音材等的多孔質吸音材差的問題。 就可解決上述問題的吸音構造體而言，形成例如使用 |呂箔或鋁薄板之如後文所述的構成是眾所週知的（例如， ^ 參照專利文獻1及2 )。以下一面參照所附圖面，一面說 明這些專利文獻1、2的吸音構造。 針對專利文獻1的隔音構造，一面參照其斜視圖的第 1 4圖、及其剖面圖的第1 5圖，一面加以說明。亦即，此 吸音構造是使例如由鋁箔等的金屬製薄膜所構成的第一薄 -5- (2) 1299853 膜41、及第二薄膜42彼此相鄰而疊層。在這些第一薄膜 41及第二薄膜42，如第15圖所示，形成有朝向這些第一 薄膜41及第二薄膜42之疊層方向之一側的多數個突部a • 。因此，根據此專利文獻1的隔音構造，當音波射入時， f 第一、第二薄膜41、42就會振動，重疊的部分會接觸而 引起摩擦，該結果便會產生音波的能量消散而可吸音。 形成上述構成的吸音構造由於是如上所述，藉由第一 φ 、第二薄膜41、42接觸而摩擦的構造使音波能量消散， 因此比起利用共振現象使音波能量消散的吸音構造，可在 更廣範圍的頻率帶域發揮優良的吸音性能。而且，第一、 第二薄膜4 1、42的材料是採用鋁等的金屬製箔片，因此 比起必須處理成破碎粉塵等的習知吸音構造之玻璃棉等的 不易回收材，吸音構造的回收較爲容易。此外，在第一、 第二薄膜41、42設有多數個微細貫穿孔。 接下來，針對專利文獻2的隔音構造，一面參照其剖 φ 面圖的第16圖，一面以該公報所使用的同一名稱加以說 明。亦即，此隔音構造是將外裝板5 1及具有多數個貫穿 孔52a的內裝板52相對向配置而構成。前述內裝板52是 將板厚、孔徑及開口率設定成可使通過貫穿孔52a的空氣 產生黏性作用，即滿足後述設計條件。此設定條件是將 ‘ 〇. 3以上之吸音率的頻率帶域寬度相對於共鳴頻率設定在 10%以上。此外，符號53爲空氣層。 根據這種專利文獻2的隔音構造’由於是使空氣產生 黏性作用，因此可促進藉由黏性作用所產生的空氣振動之 -6 - (3) 1299853 轉換成熱能的功能，該結果便可在廣大的頻率帶域寬度確 實發揮充分的吸音性能。因此，除了共鳴頻率的噪音以外 ，對於此頻率以外的噪音也可發揮優良的吸音性能。此外 k ，此專利文獻2的隔音構造的外裝板51及內裝板52是由 < 鐵或鋁等的金屬或合成樹脂所形成。 根據上述專利文獻1及專利文獻2所揭示的吸音構造 ，如上所述，比起僅利用共振現象使音波能量消散的吸音 φ 構造，可在廣範圍的頻率帶域發揮優良的吸音性能。而且 ，構成這些專利文獻1、2之吸音構造的吸音材的回收容 易，因此極爲優良。所以，只要可將這些專利文獻1、2 的吸音構造例如用來作爲快速道路用的隔音牆，對於噪音 公害的消除應該可以有很大的幫助。 然而，上述專利文獻1、2任一個公報當中都僅揭示 出基本構想，具體的構造並未揭示。 〔專利文獻1〕日本特開2004-2643 74號公報 φ 〔專利文獻2〕日本特開2003-5058 6號公報 【發明內容】 本發明是鑒於上述課題而硏創者，其目的在於提供一 > 種可在廣範圍的頻率帶域發揮優良的吸音性能，而且吸音 1 材的回收容易的隔音板。 本發明提供一種隔音板，是隔音板，其特徵爲具備： 具有矩形狀的框部、及安裝於此框部之一側的背面板、及 覆蓋前述框部之另一側的開口側，並且具備音波可通過之 (4) 1299853 複數個音波通過通路的正面板的盒體；以及收容在前述盒 體內的吸音構件，前述吸音構件具備與前述背面板及正面 板之對向方向交叉，並且朝前述對向方向疊層的複數個金 .屬構件，這些金屬構件分別具有朝前述對向方向貫穿的多 < 數個微細貫穿孔，而且從與前述對向方向正交的特定方向 看來形成波型的剖面形狀是分別形成朝前述特定方向延伸 的波型形狀，前述各金屬構件是以分別使前述波型形狀的 φ 頂部彼此接觸的狀態朝前述對向方向疊層。 根據本發明，由於是使形成波型形狀的複數個金屬構 件的頂部彼此接觸而疊層該各金屬構件的構成，因此可在 這些金屬構件之波型的凹部彼此之間形成空氣層。因此， 當音波進入此隔音板時，在前述空氣層會引起音波的共鳴 現象，開設在這些金屬構件的多數個微細貫穿孔內的空氣 會激烈振動，藉由由於空氣之黏性所產生的與貫穿孔的內 側面之間的摩擦，可使音波能量轉換成熱能’該結果’在 φ 以共鳴頻率爲中心的廣大範圍的頻率帶域就會發揮吸音效 果，對於包含共鳴頻率的廣大頻率成分的噪音會發揮優良 的吸音性能。 而且，根據本發明，由於吸音構件是由金屬構件所構 •成，因此比起必須處理成破碎粉塵等的習知吸音構造之玻 k 璃棉等的不易回收材，回收較爲容易。 又，本發明提供一種隔音板，是隔音板’其特徵爲具 備：具有矩形狀的框部、及安裝於此框部之一側的背面板 、及覆蓋前述框部之另一側的開口側’並且具備音波可通 -8 - (5) 1299853 過之複數個音波通過通路的正面板的盒體；以及收容在前 述盒體內的吸音構件，前述吸音構件具備與前述背面板及 正面板之對向方向交叉而配置的複數個第1金屬構件及第 > 2金屬構件，前述各第1金屬構件分別具有朝前述對向方 < 向貫穿的多數個微細貫穿孔，而且從與前述對向方向正交 的特定方向看來形成波型的剖面形狀是分別形成朝前述特 定方向延伸的波型形狀，前述第2金屬構件具有朝前述對 Φ 向方向貫穿的多數個微細貫穿孔，而且前述對向方向的面 爲平坦面，前述第2金屬構件及前述第1金屬構件是朝前 述對向方向交互疊層。 根據本發明，由於是將具有波型剖面形狀的第1金屬 構件、及具有平坦面的第2金屬構件交互疊層的構成，因 此波型剖面形狀的頂部會與前述平坦面接觸，藉此便可在 該各金屬構件的波型凹部與平坦面之間形成空氣層。因此 ，當音波進入此隔音板時，在前述空氣層會引起音波的共 Φ 鳴現象，開設在這些金屬構件的多數個微細貫穿孔內的空 氣會激烈振動，藉由由於空氣之黏性所產生的與貫穿孔的 內側面之間的摩擦，可使音波能量轉換成熱能，該結果， 在以共鳴頻率爲中心的廣大範圍的頻率帶域就會發揮吸音 + 效果，對於包含共鳴頻率的廣大頻率成分的噪音會發揮優 ‘良的吸音性能。 而且，根據本發明，由於吸音構件是由第1及第2金 屬構件所構成’因此比起必須處理成破碎粉塵等的習知吸 音構造之玻璃棉等的不易回收材，回收較爲容易。 -9 - (6) 1299853 又’本發明提供一種隔音板，是隔音板，其特徵爲具 備：具有矩形狀的框部、及安裝於此框部之一側的背面板 、及覆蓋前述框部之另一側的開口側，並且具備音波可通 • 過之複數個音波通過通路的正面板的盒體；以及收容在前 ^ 述盒體內的吸音構件，前述吸音構件具備與前述背面板及 正面板之對向方向交叉，並且朝前述對向方向疊層的複數 個金屬構件，這些金屬構件分別具有從與前述對向方向正 φ 交的特定方向看來形成波型的剖面形狀是朝前述特定方向 延伸的波型部；以及前述對向方向的面爲平坦面的平面部 ，而且是以前述平面部與相鄰的對方金屬構件的波型部接 觸，且前述波型部與相鄰的對方金屬構件的平面部接觸的 狀態，朝前述對向方向疊層。 根據本發明，由於是將分別具有波型部及平面部的複 數個金屬構件疊層的構成，因此波型部與對方的平面部會 接觸，而且平面部與對方的波型部會接觸，因此可在該各 φ 金屬構件的波型凹部與平面部之間形成空氣層。因此，當 音波進入此隔音板時，在前述空氣層就會引起音波的共鳴 現象，開設在這些金屬構件的多數個微細貫穿孔內的空氣 會激烈振動，藉由由於空氣之黏性所產生的與貫穿孔的內 ^ 側面之間的摩擦，可使音波能量轉換成熱能，該結果，在 ^ 以共鳴頻率爲中心的廣大範圍的頻率帶域就會發揮吸音效 果，對於包含共鳴頻率的廣大頻率成分的噪音會發揮優良 的吸音性能。 而且，根據本發明，由於吸音構件是由金屬構件所構 -10- 1299853 (7) 成，因此比起必須處理成破碎粉塵等的習知吸音構造之玻 璃棉等的不易回收材，回收較爲容易。 又，本發明提供一種隔音板，是隔音板，其特徵爲具 k 備：具有矩形狀的框部、及安裝於此框部之一側的背面板 > 、及覆蓋前述框部之另一側的開口側，並且具備音波可通 過之複數個音波通過通路的正面板的盒體；以及收容在前 述盒體內的吸音構件，前述吸音構件具備與前述背面板及 0 正面板之對向方向交叉而配置，並且具有朝前述對向方向 貫穿的多數個微細貫穿孔的金屬構件，此金屬構件是使前 述對向方向的面形成平坦面，並且相對於前述背面板及正 面板朝前述對向方向分開而配置。 根據本發明，由於可在金屬構件與背面板及正面板之 間分別形成空氣層，因此在此空氣層會引起音波的共鳴現 象，開設在這些金屬構件的多數個微細貫穿孔內的空氣會 激烈振動，藉由由於空氣之黏性所產生的與貫穿孔的內側 φ 面之間的摩擦，可使音波能量轉換成熱能，該結果，在以 共鳴頻率爲中心的廣大範圍的頻率帶域寬度就會發揮吸音 性能，對於包·含共鳴頻率的廣大頻率成分的噪音會發揮優 良的吸音性能。 _ 而且，根據本發明，由於吸音構件是由金屬構件所構 ‘成，因此比起必須處理成破碎粉塵等的習知吸音構造之玻 璃棉等的不易回收材，回收較爲容易。 【實施方式】 -11 - (8) 1299853 以下，依序參照所附圖面來說明本發明之形態的隔音 板及隔音牆。 以下說明本發明之形態1的隔音板及隔音牆。第1圖 •是本發明之形態1的隔音牆的正面圖，第2圖是本發明之 f 形態1的隔音牆所使用的隔音板的模式正面圖，第3圖是 第2圖的ΙΠ-ΙΠ線剖面圖，第4圖是第2圖的IV_IV線剖 面圖。 φ 第1圖所示的符號1是本發明之形態1的隔音牆，在 此隔音牆1使用了 1 6片形成後述構成的隔音板2。此隔音 板2是如第2圖至第4圖所示，由矩形狀的後述盒體2a、 以及收容在此盒體2 a內之後述吸音構件所構成的鋁製品 。前述盒體2a具備：矩形狀的框部2b、及安裝於此框部 2b之一側的背面板2c、以及將前述框部2b之另一側的開 口側覆蓋成可裝卸狀態，並且具有音波可通過之複數個音 波通過通路Pa的0.8mm厚度的正面板2d。在此情況下， φ 前述音波通過通路Pa是直徑爲0.8mm的貫穿孔。此外， 在將此隔音板2安裝於隔音牆框架之後，可在此隔音板2 之正面板2d的表面安裝用來使音波通過隔音板2內，並 防止雨水侵入隔音板2內的風道1 a。 ^ '前述吸音構件是使前述盒體2a之，從圖面中的上下 方向（與前述背面板2c及正面板2d之對向方向正交的特 定方向）看來形成波型的剖面形狀是形成朝上下方向延伸 的波型形狀’並且設有朝前述對向方向賃*穿的未圖示的多 數個微細貫穿孔之附縱圓弧波形的鋁薄板（金屬構件）2e -12- (9) 1299853 、以及從左右方向（與前述對向方向正交的特定方向）看 來形成波型的剖面形狀是形成朝左右方向延伸的波型形狀 ，並且設有朝前述對向方向貫穿的未圖示的多數個微細貫 穿孔之附橫圓弧波形的鋁薄板（金屬構件）2f交互疊層而 構成。在此情況下，附波形的鋁薄板是形成三層構成，但 是並不特別限定於三層構成，亦可爲兩層構成或四層構成 。亦即，附波形的鋁薄板的層數應該依樣式來決定。 此形態1之隔音牆1所使用的隔音板2當中，前述附 縱圓弧波形的鋁薄板2e及附橫圓弧波形的鋁薄板2f的厚 度皆爲〇. 1〜0.3 mm。這些附縱圓弧波形的鋁薄板2e、附橫 圓弧波形的鋁薄板2 f是在鋁薄板上，例如藉由軋輥壓延 開設直徑0.1mm左右的多數個微細貫穿孔之後，例如藉由 加壓成形施以高度尺寸爲2 0mm的圓弧波狀加工而製作。 此外，這種隔音板2是在工廠製造，然後被搬運至現場而 安裝在隔音牆框架。 以下，說明本發明之形態1的隔音牆1或隔音板2的 作用樣態。亦即，由於在作爲吸音構件之附縱圓弧波形的 鋁薄板2e的圓弧波形、與附橫圓弧波形的鋁薄板2f的圓 弧波形之間會形成空氣層，因此會引起音波的共鳴現象， 音波能量會因爲在開設於這些附波形的鋁薄板的多數個微 細貫穿孔部激烈振動的空氣之黏性作用而消散。因此，根 據本發明之形態1的隔音牆1或隔音板2，與先前技術的 情況相同’比起僅利用共振現象使音波能量消散的吸音構 造，可在更廣範圍的頻率帶域發揮優良的吸音性能。 -13- (10) 1299853 而且，根據本發明之形態1的隔音牆i或隔音板2， 由於吸音材是使用鋁薄板，因此與專利文獻1或2的隔音 構造相同，比起必須處理成破碎粉塵等之吸音構造的玻璃 . 棉等的不易回收材，回收較爲容易。 、一面參照所附圖面，一面說明本發明之形態2的隔音 牆所使用的隔音板。第5圖是經過圓弧狀波形加工之附圓 弧狀傾斜波形的鋁薄板的組裝狀態說明斜視圖。此外，使 φ 用此隔音板之形態2的隔音牆的整體構成與上述形態1的 隔音牆爲相同形狀，因此省略隔音牆之構成的說明。 亦即，此形態2之隔音板的吸音構件具備：波型的剖 面形狀是形成朝向傾斜於前述框部2b之各邊的方向延伸 的波型，並且設有多數個微細貫穿孔的複數個附傾斜圓弧 波形的鋁薄板2g，並且在這些附傾斜圓弧波形的鋁薄板 2g之相鄰的傾斜圓弧波形之間彼此交叉而交互疊層，然後 收容在未圖示的盒體內。此附傾斜圓弧波形的鋁薄板2g φ 之多數個微細貫穿孔的直徑及圓弧波形的高度尺寸是設定 成與上述形態1之情況同樣的値。 根據本發明之形態2的隔音牆所使用的隔音板，只有 在鋁薄板上加工的圓弧波形爲傾斜的這點與上述形態1之 Λ 隔音牆所使用的隔音板不同。因此，本發明之形態2的隔 '音牆所使用的隔音板具有與上述形態1之隔音牆所使用的 隔音板同樣的效果。 在以上形態1、2之隔音板的情況下，重疊之附圓弧 狀波形的鋁薄板的圓弧波形彼此是交叉而使頂部彼此接觸 -14- (11) 1299853 ，但是重疊之附圓弧狀波形的鋁薄板的圓弧狀波形彼此亦 可不交叉。例如，本發明之形態3的隔音板是以後述方式 構成。亦即，雖省略圖示，但重疊之附圓弧狀波形的鋁薄 • 板的圓弧波形彼此是朝同一個方向，並且使圓弧波形的頂 t 部彼此接觸而構成。因此，在圓弧波形之間會形成空氣層 ’所以會引起音波的共鳴現象，音波能量會因爲在開設於 這些附波形的鋁薄板的多數個微細貫穿孔部激烈振動的空 φ 氣之黏性作用而消散，因此藉由這種構成，也可獲得與上 述形態1、2之隔音板同等的效果。 一面參照所附圖面，一面說明本發明之形態4的隔音 牆所使用的隔音板。第6圖是本發明之形態3的隔音牆所 使用的隔音板的模式正面圖，第7圖是第6圖的VII-VII 線剖面圖，第8圖是第6圖的VIII-VIII線剖面圖。 本發明之形態4的隔音牆所使用的隔音板3是如第6 圖至第8圖所示，由形成與上述形態1之盒體爲相同構成 φ 的盒體3 a ;以及可收容在此盒體3 a內的後述吸音構件所 構成。前述吸音構件是形成使前述盒體3a之從圖面中的 上下方向（與正面板3d及背面板3c之對向方向正交的特 定方向）看來形成波型的剖面形狀是形成朝前述特定方向 ~ 延伸的波型，並且設有朝前述對向方向貫穿的未圖示的多 ‘ 數個微細貫穿孔之附縱圓弧波形的鋁薄板（第1金屬構件 )3 e、以及設有朝前述對向方向貫穿的多數個微細貫穿孔 的鋁薄板（第2金屬構件）3 f交互疊層的構成。 此形態4之隔音牆所使用的隔音板3之附縱圓弧波形 (12) 1299853 的鋁薄板3e是在0.1〜0.3mm厚度的鋁薄板，例如藉由軋 輥壓延而開設直徑0.1mm左右的多數個微細貫穿孔之後， 例如藉由加壓成形施以高度尺寸爲2 0mm的縱圓弧波形加 工，與上述形態1的情況相同。此外，此形態3之隔音牆 ，所使用的隔音板3是採用附縱圓弧波形的鋁薄板3 e，但是 亦可置換成使用在上述形態1之隔音牆所使用的隔音板之 附橫圓弧波形的鋁薄板。 0 又，如果錕薄板極薄，而且是形成 500mmx2000mm 左右的尺寸，則在由於其剛性的關係以致不易裝入盒體的 情況下，可形成將鋁薄板安裝在如後文所述之構成的框體 ，並將安裝有鋁薄板的框體裝入盒體的構成。在該情況下 ，藉由在盒體的上下構成零件使用具有導軌的鋁擠出構件 ，並且如拉門般沿著導軌使其滑動而推入之後，將長邊方 向之一側的縱構件固接而形成矩形狀，便可構成隔音板。 亦即，亦可在拉窗框狀的黏著框使用雙面膠帶來黏貼 φ 鋁薄板，並將此黏貼有鋁薄板的黏著框裝入盒體。另外， 亦可將通道狀的鋁構件作成使開口側朝相對之側的矩形狀 的鋁薄板安裝框，並且在此鋁薄板安裝框的凹槽有鋁薄板 的端部嵌入之嵌入剖面角狀的橡皮帶，然後以賦予張力的 ‘ 狀態安裝鋁薄板，並且將安裝有鋁薄板的鋁薄板安裝框裝 入盒體。另外，亦可作成矩形狀的鋁薄板安裝框，並且在 將鋁薄板捲繞在此鋁薄板安裝框而形成無端狀之後，將捲 繞有鋁薄板的鋁薄板安裝框裝入盒體。又，亦可在鋁薄板 安裝框之框構件的側面設置凹槽，並且將橡皮帶從鋁薄板 -16- (13) 1299853 的上側壓入凹槽，然後以所謂紗門網的方式，將鋁薄板安 裝在鋁薄板安裝框，並將安裝有鋁薄板的鋁薄板安裝框裝 入盒體。 .根據本發明之形態4的隔音牆所使用的隔音板3，與 k 上述形態1之隔音牆所使用的隔音板的情況相同，在附縱 圓弧波形的鋁薄板3 e的圓弧波形、與鋁薄板3 f的平面部 之間會形成空氣層，因此會引起音波的共鳴現象，音波能 φ 量會因爲在開設於這些附波形的鋁薄板的多數個微細貫穿 孔部激烈振動的空氣之黏性作用而消散。因此，與專利文 獻1的情況相同，比起僅利用共振現象使音波能量消散的 吸音構造，可在更廣範圍的頻率帶域發揮優良的吸音性能 ，因此具有與上述形態1之隔音牆所使用的隔音板同樣的 效果。 以下說明本發明之形態5的隔音牆所使用的隔音板。 此外，使用此隔音板的隔音牆的全體構成與上述形態1的 φ 隔音牆爲相同形狀，因此省略隔音牆的說明。 此形態5之隔音牆所使用的隔音板的吸音構件是使後 述兩種附圓弧波形的鋁薄板交互疊層而構成。亦即，在一 方之附圓弧波形的鋁薄板的四個部位的周緣部形成有朝外 ~ 方向的複數個經過圓弧波形加工的部分（波型部），除此 k 之外的中央部分（平面部）是形成平坦面。而且，在這些 圓弧波形加工區域（波型部）及平面部設有多數個微細貫 穿孔。此外，疊層在前述第1附圓弧波形的鋁薄板的另一 方之第2附圓弧波形的鋁薄板是在此第1附圓弧波形的鋁 •17- (14) 1299853 薄板的平面部，形成有頂部會與之接觸的複數個經過圓弧 波形加工的部分（波型部），除此之外的四個部位的周緣 部（平面部）是形成平坦面。而且，在這些圓弧波形加工 . 區域及平面區域設有多數個微細貫穿孔。 本發明之形態5的隔音牆所使用的隔音板當中，在一 r 方之第1附圓弧波形的鋁薄板的圓弧波形與另一方之第2 附圓弧波形的鋁薄板的平面部之間會形成空氣層，而且在 φ 另一方之第2附圓弧波形的鋁薄板的圓弧波形與一方之第 1附圓弧波形的鋁薄板的平面部之間會形成空氣層。因此 ，根據本發明之形態5的隔音牆所使用的隔音板，由於在 圓弧波形與平面部之間會形成空氣層，因此會引起音波的 共鳴現象，音波能量會因爲在開設於這些附波形的鋁薄板 的多數個微細貫穿孔部激烈振動的空氣之黏性作用而消散 ，因此本實施形態5具有與上述形態1同樣的效果。 本發明之形態1至5的隔音板的吸音構件是由附圓弧 φ 波形的鋁薄板所構成，但是亦可爲箔片，或是在表面黏貼 有纖維的板體，或是在表面黏貼有纖維的箔片。 而且，本發明之形態1至5的隔音板之作爲吸音構件 的附圓弧波形的鋁薄板的端緣是藉由後述手段當中的任一 ‘ 個而安裝在盒體的內壁。 1 )將附圓弧波形的鋁薄板的端緣，利用具有密封功能 的接著材接合在盒體。 (2

銘薄板加工的波型並不特別限定於圓弧波形。例如亦可在 鋁薄板施以四角波形加工、或施以梯形波形加工、或施以 三角波形加工，無論是何種波形，皆可發揮同等的功能。 針對本發明之形態6的隔音牆所使用的隔音板，一面 參照其模式橫切剖面圖的第9圖，一面加以說明。本發明 之形態6的隔音牆所使用的隔音板5是由矩形狀的盒體5& -19- (16) 1299853 ;以及可收容在此盒體5 a內之後述吸音構件所構成的鋁 製品。前述盒體5a具備：矩形狀的框部5b ;及安裝於此 框部5b之一側的背面板5 c ;以及將前述框部5b之另一側 . 的開口側覆蓋成可裝卸狀態，並且具有音波可通過之複數 個音波通過通路Pa的正面板5d。在此情況下，前述音波 ► 通過通路Pa是直徑爲0.8mm的貫穿孔。 前述吸音構件在與前述背面板5 c之間、與前述正面 φ 板5d之間、以及本身彼此之間，具備隔著空氣層而設置 的三片鋁箔5f。在這些鋁箔5f的端緣形成有分別設在前 述盒體5a內之上部及下部的對應位置，並且形成沿著長 邊方向的圓形剖面的孔；以及可卡止在設有從相對側與孔 連通之凹槽的三對端部卡止部5e的圓棍狀卡合構件5g。 而且，在各鋁箔5f設有多數個微細貫穿孔。這些鋁箔5f 都是藉由使前述卡合構件5g嵌插在前述端部卡止部5e的 孔而安裝。當然，安裝作業結束後，側面構件就會固接並 φ

INSTRUCTIONS OF THE INVENTION [Technical Fields of the Invention] The present invention relates to an improved technique for a sound insulating panel and a sound insulating wall, and more particularly, relates to a high recovery, light weight, and low frequency band absorption To the high ★ frequency band of the wide range of frequency band noise of the sound insulation board. [Prior Art] In the conventional sound absorbing structure, a porous sound absorbing material such as glass wool and a material having excellent weather resistance, water resistance, and heat resistance are used. However, this sound absorbing structure can make up the weather resistance, water resistance, and heat resistance of the glass wool, but it is not sufficient, and the problem of recovery is not solved. In addition, in the case of a sound absorbing structure other than the case of using a porous sound absorbing material typified by glass wool, that is, a sound absorbing structure or a plate vibration type sound absorbing structure, the following sound absorbing structure is produced. problem. In other words, since the sound absorbing structure dissipates energy by the resonance phenomenon, there is a problem in that the sound absorption rate band is narrow and the sound absorbing performance is inferior to that of a porous sound absorbing material such as a porous sound absorbing material such as glass wool. In the sound absorbing structure which can solve the above problems, it is known to form a structure as described later, for example, using a lye foil or an aluminum foil (for example, ^refer to Patent Documents 1 and 2). The sound absorbing structure of these Patent Documents 1 and 2 will be described below with reference to the drawings. The sound insulating structure of Patent Document 1 will be described with reference to Fig. 4 of the oblique view and Fig. 15 of the sectional view thereof. In other words, the sound absorbing structure is formed by laminating a first thin -5-(2) 1299853 film 41 composed of a metal thin film such as aluminum foil and a second film 42 adjacent to each other. As shown in Fig. 15, the first film 41 and the second film 42 are formed with a plurality of projections a toward one side of the lamination direction of the first film 41 and the second film 42. Therefore, according to the sound insulating structure of Patent Document 1, when the sound waves are incident, the f first and second films 41, 42 vibrate, and the overlapping portions come into contact to cause friction, and as a result, the energy of the sound waves is dissipated. Can absorb sound. Since the sound absorbing structure having the above-described configuration is such that the first φ and the second films 41 and 42 are in contact with each other and the frictional energy is dissipated as described above, the sound absorbing structure that dissipates the sound energy by the resonance phenomenon can be used. A wider range of frequency bands provide excellent sound absorption. Further, since the materials of the first and second films 41 and 42 are made of a metal foil such as aluminum, the sound absorbing structure is not easily recovered as compared with a glass wool or the like which is required to be processed into a conventional sound absorbing structure such as broken dust. Recycling is easier. Further, a plurality of fine through holes are provided in the first and second films 41 and 42. Next, the sound insulating structure of Patent Document 2 will be described with reference to Fig. 16 which is a cross-sectional view of the same. That is, the sound insulating structure is configured such that the exterior panel 51 and the interior panel 52 having a plurality of through holes 52a are opposed to each other. The inner panel 52 has a thickness, a hole diameter, and an aperture ratio which are set to make the air passing through the through hole 52a viscous, that is, to satisfy the design conditions described later. This setting condition is to set the frequency band width of the sound absorption rate of ‘3 or more to 10% or more with respect to the resonance frequency. Further, the symbol 53 is an air layer. According to the sound-insulating structure of Patent Document 2, since the air is viscous, the function of converting the -6 - (3) 1299853 of the air vibration generated by the viscous action into heat energy can be promoted, and the result can be The wide frequency band width does play a full sound absorption performance. Therefore, in addition to the noise of the resonance frequency, excellent noise absorption performance can be exhibited for noise other than this frequency. Further, k, the outer panel 51 and the inner panel 52 of the soundproof structure of the patent document 2 are < A metal such as iron or aluminum or a synthetic resin. According to the sound absorbing structure disclosed in Patent Document 1 and Patent Document 2, as described above, the sound absorbing φ structure which dissipates the sound wave energy by only the resonance phenomenon can exhibit excellent sound absorbing performance over a wide frequency band. Further, since the sound absorbing material constituting the sound absorbing structure of Patent Documents 1 and 2 is easily recovered, it is extremely excellent. Therefore, as long as the sound absorbing structure of these Patent Documents 1 and 2 can be used, for example, as a soundproof wall for a fast road, it is possible to greatly contribute to the elimination of noise pollution. However, in the above-mentioned patent documents 1 and 2, only the basic concept is disclosed, and the specific structure is not disclosed. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2004-2643 No. 2004-A. Patent Publication No. 2003-5058 No. A sound-absorbing panel that can perform excellent sound-absorbing performance in a wide range of frequency bands, and sound-absorbing 1 material is easy to recycle. The present invention provides a sound insulating panel comprising a frame portion having a rectangular shape, a back plate attached to one side of the frame portion, and an opening side covering the other side of the frame portion, and a casing having a front panel through which a plurality of sound waves pass through the passage of (4) 1299853; and a sound absorbing member housed in the casing, wherein the sound absorbing member has an opposite direction to the back panel and the front panel, and a plurality of metal members laminated in the opposite direction, the metal members having a plurality of metal members respectively penetrating in the opposite direction < a plurality of fine through holes, and a cross-sectional shape in which a wave pattern is formed from a specific direction orthogonal to the opposing direction is formed in a wave shape extending in the specific direction, and each of the metal members is respectively The state in which the φ tops of the wave-shaped shape are in contact with each other is laminated in the aforementioned opposing direction. According to the present invention, since the top portions of the plurality of metal members forming the wave-shaped shape are brought into contact with each other to laminate the respective metal members, an air layer can be formed between the concave portions of the wave-shaped portions of the metal members. Therefore, when the acoustic wave enters the baffle, the air layer causes resonance of the acoustic wave, and the air that is opened in the plurality of fine through holes of the metal members vibrates violently, due to the viscosity due to the viscosity of the air. The friction between the inner side surfaces of the through holes allows the sound energy to be converted into thermal energy. The result is a sound absorption effect in a wide range of frequency bands centered on the resonance frequency of φ, for a large frequency component including a resonance frequency. Noise will give you excellent sound absorption. Further, according to the present invention, since the sound absorbing member is made of a metal member, it is easier to recover than a non-recyclable material such as glass wool which has to be processed into a conventional sound absorbing structure such as broken dust. Moreover, the present invention provides a sound insulating panel which is characterized in that it includes a frame portion having a rectangular shape, a back surface plate attached to one side of the frame portion, and an opening side covering the other side of the frame portion. 'And having a sound wave -8 - (5) 1299853 a plurality of sound waves passing through the front panel of the passage; and a sound absorbing member housed in the casing, the sound absorbing member having a pair with the back panel and the front panel a plurality of first metal members and a second metal member disposed to intersect each other, wherein each of the first metal members has a facing side < a plurality of fine through-holes penetrating, and a cross-sectional shape forming a wave shape from a specific direction orthogonal to the opposing direction is a wave-shaped shape extending in the specific direction, and the second metal member has The plurality of fine through holes penetrating in the direction of the Φ direction, and the surface in the opposing direction is a flat surface, and the second metal member and the first metal member are alternately laminated in the opposing direction. According to the present invention, since the first metal member having the corrugated cross-sectional shape and the second metal member having the flat surface are alternately laminated, the top portion of the corrugated cross-sectional shape comes into contact with the flat surface. An air layer may be formed between the wave-shaped concave portion and the flat surface of each of the metal members. Therefore, when the sound waves enter the sound insulating plate, the air layer causes a common Φ squeaking phenomenon of the sound waves, and the air which is opened in the plurality of fine through holes of the metal members vibrates violently, due to the viscosity of the air. The friction between the inner side and the inner side of the through hole converts the sound energy into heat energy. As a result, the sound absorption + effect is exerted on a wide frequency band centered on the resonance frequency, and the frequency is wide. The noise of the ingredients will give you excellent sound absorption. Further, according to the present invention, since the sound absorbing member is composed of the first and second metal members, it is easier to recover than the unrecoverable material such as glass wool which is required to be processed into a conventional sound absorbing structure such as dust. -9 - (6) 1299853 Further, the present invention provides a sound insulating panel which is characterized by comprising: a frame portion having a rectangular shape, a back panel attached to one side of the frame portion, and a cover portion covering the frame portion a casing on the other side of the opening, and a casing having a plurality of sound waves passing through the passage; and a sound absorbing member housed in the casing, wherein the sound absorbing member is provided with the back panel and the front panel a plurality of metal members which are opposed to each other in the opposing direction of the face plate and which are laminated in the opposite direction, and each of the metal members has a cross-sectional shape which is formed into a wave shape from a specific direction intersecting with the opposite direction φ. a wave-shaped portion extending in a direction; and a plane portion in which the surface in the opposing direction is a flat surface, and the planar portion is in contact with a corrugated portion of an adjacent metal member, and the wave portion and the adjacent partner The state in which the flat portions of the metal members are in contact with each other is laminated in the opposing direction.

An air layer may be formed between the wave-shaped concave portion and the flat portion of each of the φ metal members. Therefore, when the sound waves enter the sound insulating plate, the air layer causes resonance of the sound waves, and the air which is opened in the plurality of fine through holes of the metal members vibrates violently, due to the viscosity due to the air. The friction between the inner side and the inner side of the through hole converts the sonic energy into heat energy. As a result, the sound absorption effect is exerted in a wide range of frequency bands centered on the resonance frequency, and a large frequency including the resonance frequency is used. The noise of the ingredients will exert excellent sound absorption properties. Further, according to the present invention, since the sound absorbing member is made of a metal member -10- 1299853 (7), it is more difficult to recover than a glass wool which is required to be processed into a conventional sound absorbing structure such as broken dust. easily. Moreover, the present invention provides a sound insulating board which is characterized in that it is provided with a frame portion having a rectangular shape, a back panel attached to one side of the frame portion, and another covering the frame portion. a side of the opening side, and a casing having a plurality of sound waves passing through the front surface of the passage; and a sound absorbing member housed in the casing, the sound absorbing member having an opposite direction to the back panel and the 0 front panel And a metal member having a plurality of fine through holes penetrating in the opposing direction, wherein the metal member has a flat surface formed in the opposing direction and faces the opposite direction with respect to the back panel and the front panel Configure separately. According to the present invention, since an air layer can be formed between the metal member and the back panel and the front panel, the air layer causes resonance of sound waves, and the air which is opened in the plurality of fine through holes of the metal members is intense. Vibration, by the friction between the inner side φ surface of the through hole due to the viscosity of the air, the sound energy can be converted into heat energy, and as a result, the wide frequency band width centered on the resonance frequency is It will exert sound-absorbing performance, and it will exhibit excellent sound-absorbing performance for noises of a wide range of frequency components including a resonance frequency. Further, according to the present invention, since the sound absorbing member is formed of a metal member, it is easier to recover than a non-recyclable material such as glass wool which has to be processed into a conventional sound absorbing structure such as broken dust. [Embodiment] -11 - (8) 1299853 Hereinafter, a sound insulating plate and a sound insulating wall according to a form of the present invention will be described with reference to the drawings. The sound insulating plate and the sound insulating wall according to the first aspect of the present invention will be described below. Fig. 1 is a front view of a sound insulating wall according to a first aspect of the present invention, and Fig. 2 is a front view showing a sound insulating plate used in a sound insulating wall according to a first aspect of the present invention, and Fig. 3 is a plan view of Fig. 2; The cross-sectional view of the ΙΠ line, and Fig. 4 is a cross-sectional view taken along line IV_IV of Fig. 2. φ The symbol 1 shown in Fig. 1 is a sound insulating wall according to the first aspect of the present invention, and the sound insulating wall 1 is made of 16 sheets of the sound insulating sheet 2 which will be described later. As shown in Figs. 2 to 4, the sound insulating plate 2 is a rectangular shape of a casing 2a which will be described later, and an aluminum product which is accommodated in the casing 2a and which will be described later. The casing 2a includes a rectangular frame portion 2b, a back plate 2c attached to one side of the frame portion 2b, and an open side of the other side of the frame portion 2b in a detachable state, and has an acoustic wave. The plurality of sound waves that can pass through the channel Pa. 8mm thick front panel 2d. In this case, φ the aforementioned sound wave passage passage Pa has a diameter of 0. 8mm through hole. Further, after the baffle 2 is attached to the baffle frame, the surface of the front panel 2d of the baffle 2 can be installed with a sound path for allowing sound waves to pass through the baffle 2 and preventing rainwater from entering the baffle 2. a. ^ 'The sound absorbing member is formed by forming a wave-shaped cross-sectional shape of the casing 2a from the vertical direction in the drawing (a specific direction orthogonal to the direction in which the front panel 2c and the front panel 2d are opposed) The aluminum plate (metal member) 2e -12- (9) having a longitudinal arc shape of a plurality of fine through holes (not shown) that are stretched in the upward direction 1299853 and a cross-sectional shape that forms a wave shape from a left-right direction (a specific direction orthogonal to the opposing direction) is a wave-shaped shape that extends in the left-right direction, and is provided with a non-illustrated shape that penetrates in the opposite direction. A plurality of aluminum thin plates (metal members) 2f having a circular arc shape with a plurality of fine through holes are alternately laminated. In this case, the aluminum plate with a corrugated shape is formed in a three-layer structure, but is not particularly limited to a three-layer structure, and may be composed of two layers or four layers. That is, the number of layers of the wavy aluminum sheet should be determined by the pattern. In the baffle 2 used in the sound insulating wall 1 of this aspect 1, the thickness of the aluminum thin plate 2e with the circular arc shape and the aluminum thin plate 2f with the circular arc shape are all 〇. 1~0. 3 mm. The aluminum thin plate 2e with the longitudinal arc waveform and the aluminum thin plate 2f with the circular arc shape are formed on the aluminum thin plate, for example, by rolling the roll to have a diameter of 0. After a plurality of fine through holes of about 1 mm, for example, a circular arc process having a height of 20 mm is applied by press forming. Further, the baffle 2 is manufactured at the factory and then transported to the site to be mounted on the soundproof wall frame. Hereinafter, the mode of action of the sound insulating wall 1 or the sound insulating plate 2 of the first aspect of the present invention will be described. In other words, an air layer is formed between the circular arc waveform of the aluminum thin plate 2e having the longitudinal arcuate waveform as the sound absorbing member and the circular arc waveform of the aluminum thin plate 2f having the circular arc shape, thereby causing resonance of the sound wave. In other words, the sound wave energy is dissipated by the viscous action of the air which is violently vibrated in the plurality of fine through-hole portions of the aluminum plate having the corrugated shape. Therefore, according to the sound insulating wall 1 or the baffle 2 of the first aspect of the present invention, as in the case of the prior art, the sound absorbing structure which dissipates the acoustic energy by using only the resonance phenomenon can be excellent in a wider frequency band. Sound absorption performance. Further, in the sound insulating wall i or the sound insulating board 2 according to the first aspect of the present invention, since the sound absorbing material is made of an aluminum thin plate, it is the same as the sound insulating structure of Patent Document 1 or 2, and must be processed to be broken. Glass of sound absorbing structure such as dust. Easy to recycle materials such as cotton are easy to recycle. The sound insulating panel used in the sound insulating wall according to the second aspect of the present invention will be described with reference to the drawings. Fig. 5 is a perspective view showing an assembled state of an aluminum thin plate having a circular arc-shaped inclined waveform processed by an arc-shaped waveform. Further, since the entire configuration of the sound insulating wall of the second embodiment of the sound insulating plate is the same as that of the sound insulating wall of the above-described first embodiment, the description of the configuration of the sound insulating wall will be omitted. In other words, the sound absorbing member of the sound insulating panel of the second aspect has a wave-shaped cross-sectional shape in which a wave pattern extending in a direction inclined to each side of the frame portion 2b is formed, and a plurality of fine through holes are provided. The aluminum thin plate 2g having a circular arc shape is inclined, and is alternately laminated between the adjacent inclined circular arc waveforms of the inclined circular arc-shaped aluminum thin plates 2g, and then housed in a casing (not shown). The diameter of the plurality of fine through holes of the aluminum thin plate 2g φ having the inclined circular arc shape and the height dimension of the circular arc waveform are set to be the same as those in the case of the above-described form 1. According to the sound insulating panel of the sound insulating wall according to the second aspect of the present invention, only the circular arc waveform processed on the aluminum thin plate is inclined, which is different from the sound insulating panel used in the sound insulating wall of the above aspect 1. Therefore, the sound insulating board used in the sound insulating wall of the second aspect of the present invention has the same effect as the sound insulating board used in the sound insulating wall of the first aspect. In the case of the baffles of the above aspects 1 and 2, the circular arc waveforms of the aluminum plates which are superimposed with the arc-shaped waveform are crossed with each other so that the tops are in contact with each other - 14 - (11) 1299853, but the overlapping arcs are overlapped The arcuate waveforms of the corrugated aluminum sheets may not intersect each other. For example, the sound insulating plate of the third aspect of the present invention is configured as described below. In other words, although the illustration is omitted, the circular arc-shaped waveforms of the circular arc-shaped waveforms are arranged in the same direction, and the top t portions of the circular arc waveform are brought into contact with each other. Therefore, an air layer is formed between the circular arc waveforms, so that the resonance of the sound waves is caused, and the sound energy of the sound waves is viscous due to the vibration of the air φ gas which is violently vibrated in a plurality of fine through-hole portions of the aluminum thin plates attached to the waveforms.

In addition, if the thin plate is extremely thin and is formed to a size of about 500 mm x 2000 mm, it is possible to form a frame in which the aluminum thin plate is attached as described later in the case where it is difficult to fit into the casing due to its rigidity. The body and the frame in which the aluminum thin plate is mounted are placed in the casing. In this case, by using an aluminum extrusion member having a guide rail on the upper and lower parts of the casing, and pushing it in along the guide rail as in a sliding door, the longitudinal member on one side in the longitudinal direction is fixed. The soundproof plate can be formed by forming a rectangular shape. That is, it is also possible to use a double-sided tape to adhere the φ aluminum sheet to the frame-like adhesive frame, and to attach the adhesive frame to which the aluminum sheet is pasted into the case. In addition, the channel-shaped aluminum member may be formed as a rectangular aluminum thin plate mounting frame having the opening side facing the opposite side, and the groove of the aluminum thin plate mounting frame is embedded with the end portion of the aluminum thin plate. The rubber band is then mounted in an aluminum sheet in a state of imparting tension, and an aluminum sheet mounting frame mounted with an aluminum sheet is loaded into the casing. Alternatively, a rectangular aluminum foil mounting frame may be formed, and after the aluminum thin plate is wound around the aluminum thin plate mounting frame to form an endless shape, the aluminum thin plate mounting frame around which the aluminum thin plate is wound is placed in the casing. Alternatively, a groove may be provided on the side of the frame member of the aluminum sheet mounting frame, and the rubber band may be pressed into the groove from the upper side of the aluminum sheet-16-(13) 1299853, and then the aluminum may be made by a so-called screen door mesh.

Dissipated by sexual effects. Therefore, as in the case of Patent Document 1, the sound absorbing structure that dissipates the sound energy by using only the resonance phenomenon can exhibit excellent sound absorbing performance over a wider frequency band, and therefore has the sound insulating wall used in the above-described aspect 1. The same effect of the baffle. Hereinafter, a sound insulating panel used for the sound insulating wall according to the fifth aspect of the present invention will be described. Further, since the overall configuration of the sound insulating wall using the sound insulating panel is the same as that of the φ sound insulating wall of the above-described first embodiment, the description of the sound insulating wall will be omitted.

(8) The edge of the aluminum thin plate having the circular arc shape is sandwiched by a yoke type nip forming portion formed on the inner wall of the casing. However, in the case of the baffle plates according to the first to fifth embodiments, the case where the waveform of the aluminum thin plate as the sound absorbing member used for the baffle of the sound insulating wall used for the sound insulating wall of the fast road is a circular arc waveform will be described as an example. However, the waveform processed in the Mingban plate is not particularly limited to the circular arc waveform. For example, the aluminum sheet can be processed by a four-corner wave, a trapezoidal waveform, or a triangular wave, and the same function can be performed regardless of the waveform. The sound insulating panel used for the sound insulating wall according to the sixth aspect of the present invention will be described with reference to Fig. 9 which is a cross-sectional view of the mode.

That is, according to the baffle 5, the sound insulating structure of the document 2 is the same, and it is possible to convert the air vibration generated by the viscous action into heat energy by causing the air to be viscous. The vast frequency band width does play a full performance. Thereby, in addition to the noise of the resonance frequency, the sound noise of this frequency can exhibit excellent sound absorbing performance, and therefore has the same effect as the sound insulating board used for the above-mentioned φ sound insulating wall. The sound insulating panel used for the sound insulating wall according to the seventh aspect of the present invention is referred to as a '1' cross-sectional view of the mode cross-sectional view, and the sound insulating panel 6 used for the sound insulating wall of the sixth aspect is a rectangular shape 6a; The aluminum product of the sound absorbing member can be accommodated in the casing 6a. The casing 6a includes a rectangular frame portion 6b, a back plate 6c on one side of the frame portion 6b, and a detachable side on the opening side of the frame portion 6b, and has a plurality of sound waves φ. The sound wave passes through the front panel 6d of the path Pa. In this case, the wave passage Pa is a diameter of 0. 8mm through hole. The sound absorbing member has a three-piece aluminum foil 6f interposed between the back surface plate 6c and the front plate 6d and between itself and the air layer. The end edges of the aluminum foils 6f are respectively provided at the corresponding positions of the upper portion and the lower portion of the above-mentioned inner surface, and are formed by a pair of flat strip-shaped three-ply adhesive members 6e protruding in a direction opposite to each other via a double-sided tape, and are provided in each of the aluminum foils 6f. Most of the fine through holes. In this case, the aluminum foil 6f is formed in a three-layer structure, but with the above-mentioned form 5, the sound-insulating panel is used with a patent to promote the function, and the sound absorption rate is other than the form 1 and the side. The case body of the present invention is attached to the other side. The body 6a provided on the front surface is attached to the front surface. In other words, the same condition -21 - (18) 1299853 ' is not particularly limited to the three-layer configuration, but can be changed according to the style. Further, the thickness of the aluminum foil 6f is 30 μm. Hereinafter, the sound insulating board used for the sound insulating wall of the seventh aspect of the present invention will be described. The mode of action of 6 is explained. That is, according to this baffle 6, with patents. The sound insulation structure of Document 2 is the same, and the function of converting the air vibration generated by the viscous action into heat energy can be promoted by making the air viscous, and the result can be fully utilized in the wide frequency band width. Sound absorption φ can. As a result, in addition to the noise of the resonance frequency, excellent noise absorption performance can be exhibited for noise other than the frequency, and therefore, the same effect as that of the sound insulating panel used in the sound insulating wall of the above-described aspect 1 is obtained. Further, the end edge of the aluminum foil can be attached to the inner wall of the casing by a means other than the above-described forms 6 and 7. (1) The edge of the aluminum foil is sandwiched between the opposing faces of the fitting portions of the fitting case formed of the male frame and the female frame. (Form 8) (2) The end edge of the aluminum foil is fixed by providing a mounting member with an end edge φ having a screw hole at the end edge, and fitting the end edge mounting member into a hole provided in the hole of the case. (3) the edge of the saw blade is received by the end edge protruding from the inner wall of the casing; and the screw is inserted into the inner wall side of the casing by the screw provided in the hole provided in the casing, and then pushed The pressure is fixed by the end edge pressing member of the edge of the wave-attached metal member received by the end edge receiving member.

A foil with a fiber attached to the surface. Further, by providing a plurality of separators in a direction orthogonal to the longitudinal direction of the inner portion of the sound insulating plate of the above-described forms 1 to 12, an excellent sound insulating effect can be obtained which can improve the sound absorbing effect of the sound insulating plate. More specifically, in the direction orthogonal to the above-described opposite direction, the sound wave intruding into the sound insulating plate can be made to face by providing the spacer at an interval smaller than 1 / 2 of the sound wavelength of the sound insulating object. Since the sound absorbing members are orthogonal to each other (the aforementioned opposite direction), the sound absorbing effect of the sound insulating plate is improved. Further, by providing the spacer at an interval other than a multiple of 1 / 2 of the sound wavelength of the sound insulating object, it is possible to prevent the sound wave that has entered the sound insulating plate from traveling in the direction along the sound absorbing member, and to face the sound absorbing member. The direction of the intersection travels, so the sound absorption effect of the sound insulation board will increase. Further, by providing the spacers at a plurality of different intervals, it is possible to prevent the sound absorbing performance of the sound waves entering the specific frequency in the sound insulating panel from being lowered, so that the sound absorbing effect of the sound insulating panel for a plurality of frequencies is improved. Therefore, by forming one of the three types of baffles formed as described above, the plurality of plate mounting frames of the sound insulating wall frame are respectively formed into the sound insulating wall, and the sound insulating wall having better sound insulation performance can be specifically oriented toward the sound insulating plate. When a plurality of separators are disposed in a direction in which the longitudinal direction of the inside of the casing is orthogonal (the opposite direction), any one of the following two methods may be used. -23- 1299853 (20) (1) After the sound absorbing member is disposed in the casing, a plate-shaped partition plate is provided by inserting one end side of the casing. (2) When a sound absorbing member is disposed in the casing, a plate-shaped partition plate is disposed. - In addition, the material of the separator can be metal (from the viewpoint of recycling). It seems to be ideal. It can also be resin and the material is not particularly limited. Further, the partition plate may be disposed so as to be attached to the sound absorbing member by an adhesive or the like, or to a member disposed on the end surface of the casing, and is not connected to the sound absorbing member.

It is known that the sound absorbing performance of any sound absorbing panel is extremely excellent. In the above-described first to twelfth embodiments, the material of the metal member constituting the sound absorbing member is aluminum. However, a metal plate such as a steel plate, a copper plate, a manganese plate or a titanium plate may be used. Therefore, it is not limited to aluminum. Further, the above-described first to fifteenth embodiments are merely specific examples of the present invention, and therefore the scope of the technical idea of the present invention is not limited by these forms. That is, the present invention provides a sound insulating panel comprising a frame portion having a rectangular shape, a back panel attached to one side of the frame portion, and an opening covering the other side of the frame portion. a casing having a front surface of a plurality of sound waves passing through the passage, and a sound absorbing member housed in the casing, wherein the sound absorbing member has an opposite direction to the back panel and the front panel, and a plurality of metal members laminated in the opposing direction, each of the metal members having a plurality of fine through holes penetrating in the opposing direction, and forming a wave-shaped cross-sectional shape from a specific direction orthogonal to the opposing direction Each of the metal members is formed in a wave shape extending in the specific direction, and each of the metal members is laminated in the opposing direction in a state in which the tops of the wave-shaped shapes are in contact with each other. According to the present invention, since the tops of the plurality of metal structures - 2599853 (22) forming the wave-shaped shape are brought into contact with each other to laminate the respective metal members, the concave portions of the wave-shaped portions of the metal members are formed with each other. When the sound wave enters the baffle, the air layer causes a squeak phenomenon in the air layer, and a plurality of fine through holes formed in the metal members vibrate violently, due to the viscous relationship between the air and the flank Friction can convert the sound energy into heat energy, and the wide frequency band centered on the resonance frequency will produce sound absorption performance for the noise of a wide frequency component including the resonance frequency.

In order to laminate the respective metal members with respect to the top contact, the specific directions of the respective metal members are set to be different from each other with respect to the opposite directions. Specifically, each of the metal members may be parallel to each side of the rectangular frame portion, and the metal members may be orthogonal to each other or may be set to be respectively inclined to the front frame portion. Each side, and the adjacent metal members are in the mutual direction, and an air layer is formed between the metal members.

Therefore, when the sound wave enters the sound insulating plate, the air layer causes resonance of the sound waves, and the air which is opened in the plurality of fine through holes of the metal members vibrates violently, due to the viscosity of the air. The friction between the inner side and the inner side of the through hole can convert the sound energy into heat energy. As a result, the sound absorption effect is exerted on a wide frequency band centered on the resonance frequency, and the frequency component containing the resonance frequency is widely used. Noise will give you excellent sound absorption. Further, according to the present invention, since the sound absorbing member is made of a metal member, it is more difficult to recover than the glass -28 - (25) 1299853 glass wool which is required to be processed into a conventional sound absorbing structure such as broken dust. easily.

The result is that the frequency band width of the broad range of the resonance frequency is sticky and sticky. The tone is that the back panel wave can be accommodated on the front panel and the direction of the front panel and the front panel is the inner side of the resonance of the air, in the performance of the sound -29-(26) 1299853 for the resonance frequency Noise from a wide range of frequency components will provide excellent sound absorption. Further, according to the present invention, since the sound absorbing member is made of a metal member, it is easier to recover than a non-recyclable material such as glass wool which has to be processed into a conventional sound absorbing structure such as broken white mash.

The attenuation, so that the sound absorption effect is improved. In the sound insulating plate, it is preferable that the sound absorbing member is disposed at an interval smaller than 1⁄2 of a sound wavelength as a sound insulating object in a direction orthogonal to the opposing direction, and includes a plurality of sounds extending in the opposing direction. -30- (27) 1299853 partitions. According to the baffle plate, a partition plate is provided at an interval smaller than 1⁄2 of the wavelength of the sound as the sound insulating object in the direction orthogonal to the opposing direction. .
