2. Description of the Related Art Noise emitted from automobiles is a very serious problem for residents living near roads. Therefore, measures have been taken to continuously install a sound insulating plate and a sound absorbing plate on the roadside or the median strip of the road to prevent the noise of the vehicle from leaking to the periphery of the road as much as possible. Various types of sound insulating plates have been proposed, such as those made of a transparent or translucent synthetic resin plate or the like.

When driving a car at night, the headlight of a car traveling in an oncoming lane may directly enter the eyes of the driver. In such a case, the driver gets the eyes. Being dazzled by the bright light, it is easy to drive incorrectly and cause an accident.

When houses and parks are located near roads, the lights of the headlights of automobiles illuminate the houses and parks intermittently at night, damaging the environment of the houses and parks. When the wildlife conservation area is located near the road, the environment of the wildlife conservation area is damaged because the headlights of automobiles illuminate the wildlife conservation area intermittently at night.

Therefore, various anti-glare plates have been proposed to prevent the light of an automobile headlight from directly entering the eyes of a driver in an oncoming lane or to prevent the light of an automobile headlight from leaking out of the road as much as possible. Have been installed.

FIG. 8 is an explanatory view showing an example of a protective fence to which a glare prevention plate and a soundproof wall are added. The protective fence 10 is installed along the road at the center of the road, and is attached to the protective fence 10. Sound absorbing panel 12 and protective fence 10 on the sound absorbing panel 12
The sound absorbing panel 12 has sound absorbing materials attached to both front and back surfaces thereof. As the antiglare plate 14, for example, an expanded metal is used which is formed by expanding an iron plate with slit-like cuts to form a net.

In this soundproof wall, the noise emitted from the automobile is absorbed by the sound absorbing panel 12 to reduce the noise. In addition, light emitted from the headlights of an automobile running diagonally ahead of the oncoming lane is emitted obliquely to the antiglare plate 14, and the light is blocked by the mesh portion of the antiglare plate 14 and runs in the opposite lane. You will not be able to see the driver of your car.

[0008]

By the way, the noise emitted from the automobile is absorbed by the sound absorbing panel 12, but a part of the noise comes around from above the sound absorbing panel 12. Sound absorbing panel 1
The anti-glare plate 14 is installed on the upper surface of the sound absorbing panel 1. Since the anti-glare plate 14 is made of expanded metal, the holes of the net remain in the space and are hollow.
The noise sneaking in from the upper part of 2 passes through the antiglare plate 14 as it is and leaks.

Therefore, if the antiglare plate can be provided with a sound insulation function, the noise leaking around the road is reduced, which is convenient.

According to the present invention, the scenery extending to the side of the road is not obstructed so much that the light of the headlights of the vehicle traveling in the opposite lane is blocked, and the noise of the vehicle can be reduced as much as possible. The purpose is to provide a plate.
