<p>The present invention relates to a structure for installing a maintenance panel type soundproof board, which is provides to allow a puzzle type soundproof board to be easily replaced when sound adsorption efficiency or a noise blocking function is lowered due to the damage or fracture of the soundproof board. According to the present invention, a soundproof wall is characterized in that insertion guide frames, which are elongated in the horizontal direction between the inner surface of one side of an H-shaped support and the inner surface of the other side of the other H-shaped support of both sides which are spaced at a predetermined distance and are fixedly installed so as to be vertically spaced at predetermined distance from each other and wherein independent insertion protrusions of a puzzle type soundproof plate are inserted into upper and lower guide grooves of the insertion guide frames. Front surfaces of both ends of the insertion guide frame are fixed by forming stepped portions hooked in the inside of a front surface of the H-shaped support. Insertion protrusions formed on both ends of a rear surface of a panel unit of the puzzle type soundproof board are inserted into the upper and lower guide grooves of the insertion guide frame. Narrow elastic hook protrusions formed on an upper and lower intermediate portion of the panel unit of the puzzle type soundproof plate are inserted into the upper and lower guide grooves of the insertion guide frame, and then a fixing bolt is inserted into a hole formed in the central portion of the narrowness hook groove to be coupled to the insertion guide frame.</p> |
