[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof wall and a soundproof panel mainly installed along a boundary between a roadway and a sidewalk or along a median strip to prevent noise pollution in a vehicle.

[0002]

2. Description of the Related Art For example, on general roads such as streets,
In order to prevent pedestrians and inhabitants along the road from noise pollution of vehicles, a relatively low sound barrier of about 700 to 1500 mm may be installed along the boundary between the road and the sidewalk or along the median strip. . Conventionally, as this type of soundproofing wall, for example, a soundproofing panel mounted so as to be dropped between opposing concave grooves of a column made of H-shaped steel erected on a road at a predetermined interval, As described in Japanese Unexamined Patent Publication No. 3-2009, the lower surface of the soundproof panel having a wall formed upright on one side edge of the lower surface is fixed to anchor bolts of a mortar portion provided on the side edge of a roadbed. What you did,
Etc.

[0003]

SUMMARY OF THE INVENTION Sound barriers installed on general roads such as streets are more effective than noise barriers installed on motorways such as expressways, which only need to prevent noise pollution.
In addition to preventing noise pollution, aesthetics are also required, and it is necessary that they do not impair the cityscape.
In the conventional soundproof wall as described above, little consideration is given to the cityscape. That is, in the case of the former pillar-supported soundproof wall that supports the soundproof panel by the pillar, the pillar is exposed to the front side and the rear side, and the lower side of the soundproof panel is directly fixed to the roadbed, and In the sound-insulating wall, the bolt mounting part on the lower surface is exposed on the front side or the rear side. Not preferred.

[0004] Also, in terms of workability, in the case of the former sound-insulating wall with support columns, the support columns need to be constructed, and the number of construction steps increases. In particular, since the support columns are heavy, heavy machinery such as cranes are required. The construction is not easy, and it takes time to adjust the angles of the columns in order to cope with the slopes and curves that match the road alignment. There are construction problems such as the inability to support the panel. In the latter self-supporting soundproof wall, the connecting portion of the adjacent soundproof panel has a packing material fixed to a groove formed on a side surface portion of the soundproof panel, and is connected through the packing material. Therefore, it is necessary to arrange adjacent soundproof panels with almost no gap, and there is a construction problem such that extremely high construction accuracy is required because a sound leak occurs when the gap is opened.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and to provide a soundproof wall and a soundproof panel which are excellent in aesthetic appearance and have good workability.

[0006]

In order to achieve the above object, the present invention has the following arrangement. That is, the soundproof wall according to the present invention includes a plurality of soundproof panels arranged in a row on a road at intervals, and a connection panel attached between adjacent soundproof panels, and the soundproof panel has soundproofness. At the left and right side surfaces of the panel body, mounting plates project from the lower end thereof in the longitudinal direction, and are fixed on the road by the mounting plates, and the connection panel is inserted between adjacent soundproof panels, The connection panel closes a gap between adjacent soundproof panels.
