では第３図や第４図に示すような透視性の道路用
防音壁（以下、透視性防音壁と称する）が開発さ
れるようになつてきた。
Traditionally, commonly used road noise barriers are:
As shown in Figure 2 A and B, a structure in which a sound absorbing material 4 such as glass wool is filled between a metal back plate 3 and a metal surface plate 1 having a large number of through holes 2... A sound insulating material 5 such as a rubber plate is interposed at the joint between the sound insulating walls. This type of soundproofing wall has high road noise absorption and soundproofing properties, and exhibits excellent soundproofing effects.
This has the disadvantage that the driver feels uncomfortable because the outside scenery is completely blocked. For this reason, transparent soundproof walls for roads (hereinafter referred to as transparent soundproof walls) as shown in FIGS. 3 and 4 have recently been developed.
第３図に示す透視性防音壁は、前記第２図イ，

色として見ることができるのである。 The transparent soundproof wall shown in FIG.
Vertically long slits 6 are arranged at regular intervals on a metal soundproof wall as shown in B, and the width of each slit 6 is expanded in a tapered manner from the front plate 1 side to the back plate 3 side. This is what I did. That is, the driver can see the intermittent scenery outside the wall due to the slits 6 as a continuous scenery due to the retinal phenomenon of the eyes while driving.
第４図に示す透視性防音壁は、透明で、遮音効

ズの板７に形成し、これらを金属枠１４で補強し
て防音壁としたものである。 The see-through soundproof wall shown in FIG. 4 is made of transparent, highly sound-insulating, and certain-strength plastic, such as polycarbonate resin, formed into plates 7 of a desired size, which are reinforced with a metal frame 14. It was designed as a soundproof wall.
しかしながら、前記第３図および第４図に示し
た透視性道路用防音壁には、いずれも次のような
問題がある。
However, the transparent road soundproof walls shown in FIGS. 3 and 4 have the following problems.
すなわち、第３図の透視性防音壁は、壁面の多
数のスリツト６……を通して道路側の騒音が外部
へ透過してしまうため、肝心の防音効果が大巾に
低下すること。 That is, in the transparent soundproof wall shown in FIG. 3, noise from the road side is transmitted to the outside through the many slits 6 in the wall surface, so that the essential soundproofing effect is greatly reduced.
第４図の透視性防音壁は、プラスチツクの一重
壁構造であるため、第２図イ，ロに示すような二
重壁構造の防音壁に比べて防音効果が低く、また
強度的にも金属製の防音壁よりかなり劣ることで
ある。 The transparent soundproof wall shown in Figure 4 has a single wall structure made of plastic, so it has a lower soundproofing effect than the soundproof wall with a double wall structure as shown in Figure 2 A and B. This is considerably inferior to a manufactured soundproof wall.
本考案は、このような従来の問題を解決するた

In general, a double wall structure has higher sound insulation properties than a single wall structure with a larger wall thickness (mass) (mass law). Since the soundproof wall 8 of the present invention has a double wall structure consisting of a plastic plate 12 and a metal plate 10, it has higher sound insulation performance than a soundproof wall having a single wall structure made of only plastic plates or metal plates.
Furthermore, noise from the roadway 9 is effectively absorbed in the internal cavity between the corrugated metal plate 10 and the transparent plastic plate 12. Therefore, it exhibits a very high soundproofing effect.

The corrugated metal plate 10 has a large number of through holes 2 on the entire surface.
... are provided, so the driver can continuously view the scenery outside the wall through these through holes 2.
