There was a problem that it could not be adequately addressed for use at construction sites.

  Therefore, the applicant of the present invention embeds a phenol foam 34 in a large number of cells 33 of the honeycomb panel 32 as a soundproof panel that is preferably used by being mounted inside the temporary enclosure. The application of the honeycomb panel 32 covered with the cover 35 was previously filed.

  For example, as shown in FIGS. 9 and 10, such soundproof panels are arranged one by one along the upper and lower sides of the plate body 36 of each temporary enclosure board B surrounding the construction site and the material storage area. If the stop plate 38 is spanned between the both side surfaces 37 and both ends of the stop plate 38 are fixed to the screw holes provided in the bent portions 37a of the both side surfaces 37 with screws 39, The upper and lower sides of the temporary enclosure B are mounted.
