As a result, the mounting bracket for the soundproof panel disclosed in Patent Document 1 can be used to replace the lower soundproof panel and to install the soundproof panel even when a plurality of soundproof panels are installed side by side between adjacent columns. It is said that the mounting work 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. Moreover, since the mounting bracket of the soundproof panel 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 used as a means to prevent the soundproof panel from falling, there is a problem that it cannot be easily constructed 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, although the sound insulation wall disclosed in Patent Document 2 can improve the aesthetics and the corrosion resistance by covering the supporting member having an H-shaped cross section with the cover member, the sound insulation panel cannot be prevented from falling off. 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 valve tight. The structural member connecting piece of the connecting member is connected to the structural member via a fixture such as a bolt and nut.

  However, in the airtight shelter disclosed in Patent Document 3, the connecting member is connected to the soundproof panel and the structural material via a fixture such as valve tight and a fastener such as a bolt and nut. In order to be used in order to prevent falling off, it is necessary to drill holes in the soundproof panel and the structural material for newly mounting these fixtures, and it is difficult to perform construction on site. There was a point.
