PROBLEM TO BE SOLVED: To provide a gap filled structure in which sound leakage is prevented by filling gaps between neighboring sound absorption panels, between neighboring sound-proof walls and between the sound absorption panel and a ballast.SOLUTION: In a gap part between neighboring panels (1) and (2), in a neighboring side part of one panel (1), a member (22) of which the cross section is U-shaped including a protrusion (23) turned toward the other panel (2) is provided so as to cover the side part. In a neighboring side part of the other panel (2), a recess (24) corresponding to the protrusion (23) is formed. An installation position of the U-shaped member (22) can be adjusted in a neighboring direction in such a manner that the protrusion (23) is fitted into the recess (24) each other. Even when a gap between the neighboring panels (1) and (2) is fluctuated, the gap is filled at all the time. |
