PROBLEM TO BE SOLVED: To provide a gap filling structure for preventing sound leakage by filling a gap between adjacent sound absorbing panels, a gap between adjacent sound insulating walls, and a gap between the sound-absorbing panel and a ballast.SOLUTION: In a gap between a lower end of a panel 1 and a ballast 32, one laterally long rectangular sound insulating plate 33 for closing the gap is disposed on the lower end of the panel 1. A long hole 47 long in a vertical direction is provided on both ends of the sound insulating plate 33. A vertical installation position of the sound insulating plate 33 can be adjusted by a bolt 48 and a nut 49 passing through the long hole 47 and penetrating through the panel 1. By this structure, the gap is constantly closed by the closing plate 33 even when the gap between the lower end of the panel 1 and the ballast 32 is fluctuated.SELECTED DRAWING: Figure 1 |
