PURPOSE: A detachable hybrid soundproof board is provided to firmly fix a front board by a cover combined with an insertion-fitting method and to facilitate the replacement of the front board when being damaged. CONSTITUTION: A detachable hybrid soundproof board comprises a sound-absorbing material, a front board(30), a rear board(20), a side board(40), a bracket(60), and a cover(80). A fixing bolt(70) fixes the bracket by touching the front upper and lower sides of the rear board with the upper and lower sides of the front board. An insertion elastic protrusion(81) inside the cover is inserted into the insertion elastic piece(61) of the bracket for combining. An offset space is formed by installing a fixing member in between the front board and the middle surface of an H-beam to facilitate the replacement. |
