[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to soundproof walls provided on both sides of a highway.

[0002]

2. Description of the Related Art Soundproof walls are provided on both sides of an expressway near a school or a residential area near a residential area for the purpose of preventing noise generated by a car running on an expressway. Also, some soundproof walls are provided on the road side of the Shinkansen. The noise barriers have different heights depending on the environment around the road, and also have different facility ranges. As a material of the soundproof wall, a concrete plate, an asbestos board, a glass wool, or the like that reflects noise and has a high sound absorbing effect has been used.

[0003] A soundproof wall in which a sound-absorbing material is covered with a metal back plate and a metal front plate provided with countless horizontal holes has also been devised. (For example, Japanese Utility Model Publication No. 52-133508) Since sound-absorbing materials use many non-combustible materials and harmful substances that generate pollution when incinerated, they can be incinerated if the sound-insulating wall is aged or damaged by a collision with a car. And the waste material were separated and processed.

[0004]

[Problems to be Solved by the Invention] If a large number of soundproof walls are to be discarded in the future, there is a problem that it is difficult to secure a dumping place. Further, there is a problem that as the sound absorbing efficiency of the sound insulating wall is improved, the structure becomes complicated and the cost increases.
The present invention has been made in view of the above-mentioned problems of the related art, and an object of the present invention is to provide a soundproof wall that can be assembled to any size and that can be reproduced. .

[0005]

In order to achieve the above object, a soundproof wall according to the present invention comprises a core material made of a renewable material, a renewable back plate attached to the back surface of the core material, And a front plate made of aluminum alloy that covers the front side of the core material from the back plate. The front plate includes an upper member, a lower member, and an intermediate member that is continuously fixed between the upper and lower members. A female connecting portion is provided at the lower portion of the member, and a male connecting portion is provided at the upper portion of the lower member and the intermediate member to partially overlap and reinforce the female connecting portion, thereby forming a reinforcing portion projecting inward on the plate wall of the intermediate member. Things.

[0017]

[Effect of the Invention] Since the soundproof wall of the present invention is configured as described above, the following effects can be obtained. Since the core material constituting the soundproof wall, the back plate attached to the back surface thereof, and the front plate body covering the front side of the core material from the back plate are all formed of a renewable material, the soundproof wall is Even if it is damaged by aging or collision of a car, it can be recovered and easily regenerated. As a result, it has a remarkable effect on the effective use of resources.

Further, the top plate is composed of an upper member, a lower member, and an intermediate member which is continuously fixed between the upper and lower members. Since the male connection part is formed by partially overlapping and reinforcing the female connection part, and the intermediate members are successively arranged between the upper and lower members, an arbitrary height can be obtained by forming several types of intermediate members having different plate widths. The soundproof wall can be easily constructed and can be provided at low cost.
