A Soundproofing panel fixing structure for soundproof tunnel

摘要

The present invention relates to a soundproof panel fixing device for a loop of a tunnel soundproof wall. The present invention is arranged between the struts installed along both sides of the road and the struts adjacent to the struts and the neighboring struts in the vehicle driving direction to connect the side wall frame and the side wall frame and the side wall frame facing each other with a beam to the beam In the tunnel soundproof wall that the soundproof panel is combined to form a roof frame, The sound insulation panel is fixed by a panel fixture fixed to the beam; The panel fixture, A vertical piece that is vertically fixed to the beam and installed along a road width direction; A guide groove is fixed to the vertical piece through a fastener and a nut is inserted in a longitudinal direction at a center thereof, and a guide groove for locking is formed, and the soundproof panel is placed on both sides of the upper surface centered on the guide groove so as to be seated. The panel fixing frame is formed; A cover member having four pressing portions formed on the bottom edges of the plurality of sound insulation panels contacting the edges of the sound insulation panels, the four pressing parts formed on the bottom edges of the plurality of sound insulation panels mounted on the seating surfaces, respectively; And a locking bolt fastened to the nut through the center of the cover member so that the cover member is pressed and fixed to each corner of the soundproof panel.
