SOUND INSULATION PLATE AND SOUNDPROOF WALL USING THE SAME
To easily perform inspection work on the back side from the front side while securing sound insulation performance with a simple structure in a soundproof wall provided with a sound insulation plate between supports.SOLUTION: A sound insulation plate 1 for constructing a soundproof wall is provided with an inspection through-hole 16 of a simple structure penetrating from a front surface part to a back surface part in a lower part of a part close to a support, and a bolt or the like used for a support mounting part on the back surface side can be easily inspected through the inspection through-hole 16 of the sound insulation plate 1 from the front surface side of the soundproof wall; and the inspection through-hole 16 and the storage space of a sound absorbing material 14 are partitioned by wall members 19, 20, 21, 22, and a door 17 for opening and closing the inspection through-hole 16 is provided to secure sound insulation performance in a normal time other than the inspection time.SELECTED DRAWING: Figure 4
【課題】支柱間に遮音板を設けた防音壁において、簡素な構造で、遮音性能を確保しつつ背面側の点検作業を正面側から容易に行えるようにする。【解決手段】防音壁を構築する遮音板１に、支柱寄りの部位の下部で正面部から背面部へ貫通する簡素な構造の点検用貫通口１６を設けて、防音壁の正面側から遮音板１の点検用貫通口１６を通して背面側の支柱取付部に使用されているボルト等を容易に点検できるようにするとともに、その点検用貫通口１６と吸音材１４の収納空間とを壁部材１９、２０、２１、２２で区画し、点検用貫通口１６を開閉する扉１７を設けることにより、点検時以外の通常時における遮音性能が確保されるようにしたのである。【選択図】図４
