SOUND PROOF APPARATUS FOR SOUND PROOF WALL
PROBLEM TO BE SOLVED: To obtain an inexpensive sound proof wall including a sound proof apparatus A having high sound proof efficiency.SOLUTION: A sound proof apparatus A is mounted on a top section of a sound proof wall B along a longitudinal direction of a road, has front and rear wall plates 11 and 12 which are arranged side by side in a vertical direction, an intermediate plate 14 between the front and rear wall plates, and a bottom plate 13 for closing a lower surface of each plate, and forms an acoustic tube S between the front and rear wall plates 11 and 12 and the adjacent intermediate plate 14. The bottom plate 13 is inclined downward from the rear wall plate 12 toward the front wall plate 11. A lower end of the intermediate plate 14 is made into an inclined piece 14a which does not lead to the bottom plate 13 and is inclined toward the front wall plate 11. The interval between each of the front wall plate 11, the intermediate plate 14, and the rear wall plate 12 and each of the adjacent plates is made 10 cm or more. The height of the intermediate plate 14 is made 10 cm or more. The interval between the front and rear wall plates 11 and 12 is made 1 m or less. The height from a lowermost end to an uppermost end of the acoustic tube S is made 1 m or less.SELECTED DRAWING: Figure 8B
【課題】安価な防音効率の高い防音装置Ａを備えた防音壁を得る。【解決手段】道路の長さ方向に沿った防音壁Ｂの頂部に取付けられ、上下方向の並列する前後壁板１１、１２と、その前後壁板間の中間板１４及びその各板下面を塞ぐ底板１３とを有して、その前後壁板１１、１２と隣接する中間板１４との間で音響管Ｓを形成した防音装置Ａである。底板１３は、後壁板１２から前壁板１１に向かって下り傾斜とし、中間板１４の下端は底板１３に至らずに前壁板１１に向かって傾斜する傾斜片１４ａとする。前壁板１１、中間板１４、後壁板１２のそれぞれ隣接する板との間隔を１０ｃｍ以上、中間板１４の高さを１０ｃｍ以上、前後壁板１１、１２の間隔を１ｍ以下、及び前記音響管Ｓの最下端から最上端までの高さを１ｍ以下とする。【選択図】図８Ｂ
