SUPPORT SOUND-ABSORBING COVER FOR SOUNDPROOF WALL OPENING, AND SOUND ABSORPTION-TYPE SOUNDPROOF WALL
PROBLEM TO BE SOLVED: To enable a reduction in noise, which is leaked to the side of a private house from a soundproof wall opening, by arranging a sound-absorbing cover on an H-shaped steel support at a terminal end of the soundproof wall opening.SOLUTION: A transparent resin sound-insulation plate 8 or a steel plate sound-insulation plate 11 is arranged on an H-shaped steel support 2 at a terminal end of a soundproof wall opening in such a manner that three pieces constituting a square cylinder are made of a translucent film-vibration acoustic board 7 or an aluminum-fiber porous acoustic board 10 and that corner parts are diagonally connected on the inside thereof, and an internal sound-absorbing material 6 is internally provided. A support sound-absorbing cover 1 for the soundproof wall opening, and a sound absorption-type soundproof wall are characterized as above.
【課題】 防音壁開口部の端末のＨ型鋼支柱に吸音カバーを配設することにより、当該開口部から民家側に漏れる騒音を低減することが可能となる。【解決手段】 防音壁開口部の端末のＨ型鋼支柱２に、四角筒を構成する三片を、透光型膜振動吸音板７あるいはアルミニウム繊維多孔質吸音板１０で構成し、その内部にコーナー部を対角状に結ぶように、透明樹脂製遮音板８あるいは鋼板製遮音板１１を配設するとともに、内部に内部吸音材６を具備したことを特徴とする、防音壁開口部の支柱吸音カバー１および吸音型防音壁にある。【選択図】 図１
