<p>The present invention relates to a bidirectional ventilation type soundproof board for a soundproof wall. The purpose of the present invention is to form bidirectional ventilation through a soundproof wall by arranging a zigzag-shaped acoustic board, coated with an absorbing material, in a hexahedral frame combined with a mesh net or punch type cover but forming a ventilation hole on a zigzag surface of the acoustic board. To achieve the purpose, the soundproof board for a soundproof wall, capable of blocking a noise from vehicle driving by being installed between supports stood on foundation concrete at predetermined intervals, includes a hexahedral frame formed through a pipe or angle; a plurality of soundproof boards installed in the frame at predetermined intervals and formed into a shape of a zigzag-shaped curved panel but forming bidirectional ventilation by forming a plurality of ventilation holes on only one zigzag surface among diagonal or reverse-diagonal zigzag surfaces; a cover formed into a shape of a punch or mesh net and installed in the frame; and a finishing panel finishing right and left surfaces and upper and lower surfaces of the frame.</p> |
