SOUND ABSORPTIVE PANEL AND SOUND INSULATION MEASURE FACILITY
PROBLEM TO BE SOLVED: To iteratively use a sound absorptive panel by simple repair even if an appearance of the sound absorptive panel is damaged.SOLUTION: A sound absorptive panel comprises an outer frame body 7 which is disposed further at an upper side of a top of the sound absorptive panel, in which a sound absorption space mounting a sound absorber 6 insides is formed, and which freely forms a partition wall separating a sound source from the surroundings of the sound source. A sound permeation face that a sound can enter and leave over the sound absorption space and the outside is formed over a sound source side front part, a back part and a ceiling part of the outer frame body 7. The outer frame body 7 is configured by providing a main frame body 10 surrounding a bottom part, both right and left side parts and a ceiling part with respect to the sound absorber 6 in a state where a sound permeation state at a sound source side, a back side and a ceiling side with respect to the sound absorber 6 is not disturbed, providing a porous tabular body 11 covering the sound source side front part, the back part and the ceiling part of the sound absorber 6 from the outside, and providing a holding and fixing member 12 for holding the porous tabular body 11 with respect to the main frame body 10 and fixing it in a freely removable manner while supporting the sound absorber 6 with the main frame body 10.SELECTED DRAWING: Figure 9
【課題】吸音パネルの外観が傷んでも簡単な補修により繰り返し使用できるようにする。【解決手段】防音パネルの最上部の更に上に配設し、吸音材６を内装した吸音空間を内部に形成すると共に、音源とその音源の周囲とを隔てる隔壁を形成自在な外枠体７を設け、吸音空間とその外方とにわたる音の出入りを可能にする音透過面を、外枠体７の音源側表面部及び、背面部、並びに天井部に形成し、外枠体７を構成するのに、吸音材６に対する音源側、背面側、天井側の音透過機能を阻害しない状態で、吸音材６に対する底部、左右両側部、天井部、を取り囲む主枠体１０を設けると共に、吸音材６の音源側表面部、背面部、並びに天井部を外側から覆う多孔板状体１１を設け、吸音材６を主枠体１０で支持した状態で、多孔板状体１１を前記主枠体１０に対して挟み込んで着脱自在に固定する挟み込み固定部材１２を設けてある。【選択図】図９
