A CHANGABLE SOUNDPROOFING PANEL

摘要

PURPOSE: A separable soundproof panel is provided to facilitate the maintenance of a soundproof panel because the front panel can be separated when necessary. CONSTITUTION: A separable soundproof panel(10) comprises a front panel(20) and a sound-absorbing material(30). The front panel having a plurality of sound absorption holes is assembled as the ends are inserted in grooves of flanges of spaced H-beams. The sound-absorbing material is arranged between a rear element(15) with a front recess and the front panel. The rear element comprises a partition(12) which is formed in the inner center of the rear element, supporting parts(13,14) which are formed between the partition and both ends, and a peripheral part(16) whose both ends are arranged in the grooves of the flanges in order to expose internal raised parts(17).
