<p>PROBLEM TO BE SOLVED: To provide a soundproof panel in which a sound insulation plate is mounted to a frame body without providing a mounting hole for screwing or the like in the sound insulation plate and the sound insulation plate is unlikely to be removed from the frame body to which the sound insulation plate has been mounted.SOLUTION: The soundproof panel comprises a rectangular sound insulation plate and a frame body including frame members which are mounted to four sides of the sound insulation plate. In the frame member, a recessed groove is formed into which an edge of the sound insulation plate is inserted. In the recessed groove, a stopper part protruding inwards is formed in a dovetail-groove shape at an opening side. A mounting member is affixed and mounted to the edge of the sound insulation plate without opening a mounting hole in the sound insulation plate. When such a force as to pull the sound insulation plate out of the recessed groove acts on the sound insulation plate, the mounting member is stopped in the stopper part of the recessed groove, and the sound insulation plate is prevented from being dropped from the frame body. The mounting member is affixed and mounted without providing the mounting hole in the sound insulation plate, such that a glass plate or a solar cell panel for which hole processing is difficult can be easily used for the sound insulation plate.</p> |
