Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound-insulating glare which is installed on a roadside or a median strip in an urban area and has a sound-insulating property and a function of preventing dazzling due to light from a headlight of an oncoming vehicle. It relates to the prevention plate.

[0002]

2. Description of the Related Art Noise emitted from automobiles is a very serious problem for residents living near roads. Therefore, we installed sound insulation boards and sound absorption boards continuously on the side of the road and on the median strip,
Measures have been taken to prevent the noise of automobiles from leaking around 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. 11 is an explanatory view showing an example of a soundproof wall provided with a glare prevention plate. A protective fence 10 installed along the road at the center of the road, and a sound absorbing panel 12 attached to the protective fence 10. And a glare prevention plate 14 mounted on the sound absorbing panel 12 via the protective fence 10. 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 and attenuated by the sound absorbing panel 12. In addition, light emitted from the headlights of an automobile running diagonally forward 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. It will not be directly visible to the driver of the existing 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.

[0011]

The anti-glare plate according to the present invention is characterized in that an anti-glare material is provided inside a translucent plate. Here, the plate-shaped body is composed of a pair of plate-shaped materials facing each other at a predetermined interval, and the antiglare material may be sandwiched between the pair of plate-shaped materials. The antiglare material may be embedded inside.

Further, the antiglare material means a material having a property of shielding light entering from an oblique direction, and examples thereof include expanded metal, punching metal, glass cloth or non-woven fabric. As a material for the antiglare material, steel, stainless steel, aluminum, opaque synthetic resin, or the like can be used.

Further, the translucent plate member includes not only a transparent plate member but also a semitransparent plate member. As a material for the plate-like member, a synthetic resin such as a polycarbonate resin or an acrylic resin, or glass can be used.

The surface of the antiglare plate may be coated with a photocatalytic function. The photocatalyst means a substance having a function of decomposing and removing stains such as organic substances by irradiation of light. TiO for coating with photocatalytic function
₂ (titanium oxide) is included,
Other components may be included as long as they have a function of decomposing and removing stains such as organic substances by light. .

The antiglare plate may be installed on the road as it is, may be installed on a protective fence, may be installed on a soundproof wall, or may be a vertically connected protective fence and a soundproof. It may be mounted further above the wall.

A transparent polycarbonate resin is used as the plate-like body 18.

The antiglare plate 14 is installed, for example, on the roadside of the city or on the median strip in parallel with the road.

Light coming from a headlight of an automobile in an oncoming lane obliquely enters the antiglare plate 14 and is shielded by an antiglare material (expanded metal) 16 to prevent glare.
Light from the lateral direction of the antiglare plate 14 passes through the holes of the antiglare material (expanded metal) 16 and reaches the driver or the like, so that the driver or the like can see the scenery to some extent.

Further, the noise emitted from the automobile is prevented by the antiglare plate 1.
However, since the opening (through hole) is not formed in the antiglare plate 14, the noise that hits the antiglare plate 14 is reflected and does not easily leak to the opposite side of the antiglare plate 14.

As a method of installing the anti-glare plate 14, the anti-glare plate 14 may be installed alone as shown in FIG. 7, or as shown in FIG. It may be installed in combination with, or as shown in FIG. 9, it may be installed in combination with a low-rise type soundproof wall 24, or as shown in FIG. 10, a low-rise type soundproof wall 24 and a protective fence 22.
