A CLAMP STRUCTURE FOR UPPER PLATE FIXING OF SOUNDPROOFING TUNNEL

摘要

The present invention relates to a clamp structure for fixing the upper plate of the tunnel soundproof wall. The present invention is a clamp structure for fixing the upper plate (P) on the upper side of the upper frame (G) constituting the tunnel soundproof wall, the frame that is raised along the longitudinal direction on the upper frame (G) and fixed through the fastening means (100); A mounting portion 200 provided on the upper side of the frame 100 and having a pair of locking projections 210 and 220 so that the ends of the upper plate P are horizontally maintained on both sides and are respectively locked and positioned in a corresponding state. ); The intermediate contact portion 320 is in close contact between the locking protrusion 210 and the locking protrusion 220 and is bent to press and support both ends of the upper plate P corresponding to each other at both ends of the contact protrusion 320. An upper plate fixture 300 forming the pressure plates 330 and 340; It is configured to pass through the contact portion 320 at the center of the upper plate fastener 300 and include a locking tool 400 that is screwed to the inner rib 420 of the frame 100. The present invention has the advantage of maintaining a stable fixed state by being coupled through a frame when the upper plate is arranged and fixed to the upper frame of the tunnel soundproof wall.
