As a result, the soundproof panel mounting bracket disclosed in Patent Document 1 can be used for replacement work of the lower soundproof panel and for the soundproof panel even when a plurality of stages of soundproof panels are arranged side by side in the height direction between adjacent columns. It is said that the work of attaching to the support can be simplified.

However, the mounting bracket for the soundproof panel disclosed in Patent Document 1 is only for mounting the soundproof panel to the support column, and does not prevent the existing soundproof panel from falling off. Further, since the soundproof panel mounting bracket disclosed in Patent Document 1 requires a fixed portion to be fixed to the soundproof panel, it is necessary to bother to provide the fixed portion on the soundproof panel in order to mount the mounting bracket. Therefore, when it is used to prevent the soundproof panel from falling, there is a problem that it cannot be easily installed on site.

The sound insulation wall disclosed in Patent Document 2 is characterized in that a flange portion of a support member having an H-shaped cross section is covered with a cover member.

However, the sound insulation wall disclosed in Patent Document 2 has a problem that the sound insulation panel cannot be prevented from falling off, although the aesthetic appearance and corrosion resistance can be improved by covering the support member having an H-shaped cross section with the cover member. was there.

The airtight shelter disclosed in Patent Document 3 includes a structural material, a soundproof panel, and a connecting member, and a panel connecting piece of the connecting member arranged along the structural material is attached to the soundproof panel via a fixture such as a valve tight. It is connected, and the structural material connecting piece of the connecting member is connected to the structural material via a fixture such as a bolt or nut.

However, in the airtight shelter disclosed in Patent Document 3, since the connecting member is connected to the soundproof panel and the structural material via a fixture such as a valve tight and a fixture such as a bolt nut, the existing soundproof panel can be used. In order to be used to prevent falling off, it is necessary to newly drill holes in the soundproof panel and structural material for mounting these fixtures, and there is a problem that construction cannot be easily performed on site. There was a point.
