ない。[Conventional technology] Progress will be made as the development of today's high-speed automobile networks and high-speed railway networks, as well as the development of transportation routes for high-speed vehicles such as maglev trains, which are scheduled to be put into practical use in the near future, will progress. The more accidents and damage caused by noise caused by vehicles traveling at high speeds occur, the more safety measures and measures to prevent damage caused by noise must be taken.

悪影響を及ぼすことも不可避的である。 In other words, as the speed of vehicles such as automobiles that travel at high speed increases, the risk of causing noise damage to the surrounding environment naturally increases. especially,
In a country as small as Japan, there is often no room for large-scale evergreen forest belts as buffer zones, and it is difficult to construct these traffic routes while avoiding densely populated residential areas. It is also inevitable that it will have a negative impact on densely populated residential areas.

与える可能性があるという問題もあつた。 For this reason, improvement measures have been studied for a long time, such as the installation of non-light-transmitting sound-absorbing walls mainly made of metal or other materials along traffic routes, and the installation of second walls along traffic routes.
This is realized by installing a light-transmitting sound insulating wall 21 mainly made of transparent or matte plastic material as shown in the figure. However, non-light-transparent sound-absorbing walls violate the right of sunlight to the surrounding environment, reduce the sense of distance and speed due to poor visibility to the side, and cause psychological pressure and discomfort. Problems such as deterioration of the driving and boarding environment have been pointed out. On the other hand, regarding the translucent sound insulating wall 21, if the speed of the vehicle C traveling on the traffic road R is 70 km/h, the driving visibility θ 1 is approximately
65°, and in that case, the light-transmitting sound insulating wall 2 of the line of sight 11 of the left limit point of the driver
The angle of incidence θ 2 on 1 is about 32.5°, and most of it is reflected, making it impossible to see through it.
In addition, although the use of the translucent sound insulating wall 21 alleviates the problem of violation of the right of sunlight to the surrounding environment to some extent, the reflection of sunlight and the headlights of oncoming cars may cause a sense of dazzle to the driver, creating a danger. In addition to this, there was also the problem that reflected light could cause a nuisance to the surrounding environment.

みも既になされている。 To solve this problem, for example, a ``transparent sound insulation material for traffic roads'' (Tokuko Showa), which is made of a transparent rigid board material with a large number of vertically striped translucent parts parallel to each other at regular intervals, has been developed. Attempts have already been made to solve this problem by providing a solution (see Publication No. 61-35327).
［考案が解決しようとする問題点］

の多くは確かに改善することができる。[Problems to be solved by the invention] By the way, if the above-mentioned "transparent sound insulating material for traffic roads" is used, problems will arise when the non-transparent sound absorbing wall or the transparent sound insulating wall 21 is installed. Many of the problems that existed can certainly be improved.

In addition, forming a large number of vertically striped translucent portions parallel to each other at regular intervals on a transparent rigid plate material is complicated in terms of work, and there is also the problem of increased product cost.

定することができる。 FIG. 1 is a plan view showing the installation situation of a sound insulating wall material 1 as an embodiment of the present invention.
It is formed as a continuum that alternates in a zigzag pattern. Of these, the see-through wall portion 2 is arranged at an inclination angle θ 3 that is substantially perpendicular to the line of sight 11 from the side of the vehicle C traveling on the traffic route R. Further, the non-see-through wall portion 3 is
They are arranged so as to be inclined in a substantially right-angled direction so as to have a flying geese-like positional relationship with respect to the see-through wall portion 2 .
The specific bending situation between the see-through wall 2 and the non-see-through wall 3 corresponds to the average speed of a vehicle C such as a car traveling on the traffic route R on which the sound insulation wall material 1 is installed. Determined by Specifically, for example, it is said that the driving field of view θ 1 of the driver in the vehicle C traveling at 70 km/h is approximately 65°, and in this case, the positional relationship is perpendicular to the line of sight 11 of the left limit point. In this way, the see-through wall portion 2 is installed. In addition, among the pair of non-see-through walls 3 that are connected to the see-through wall 2, the non-see-through wall 3 located on the lower side in the figure is at a right angle that is inside the see-through wall 2. In this direction, the non-see-through wall portions 3 located on the upper side are bent in the outward orthogonal direction, respectively.
The sound insulating wall material 1 is formed by forming the transparent wall portion 2 and the non-transparent wall portion 3 into a zigzag-like continuous body. Therefore, when the average traveling speed of the traveling object C becomes faster, the driving field of view θ 1 also becomes narrower, and conversely, as the average traveling speed of the vehicle C becomes slower, the driving field of view θ 1 becomes wider, so that each driving field of view θ 1 becomes narrower. Line of sight at left limit point 1
1, the inclination angle θ 3 of the see-through wall portion 2 can be set in a Y positional relationship that is not substantially perpendicular to the line of sight 11.

ことができる。 The sound insulating wall material 1 is formed in such a bent shape between the see-through wall portion 2 and the non-see-through wall portion 3.
is entirely made of a rigid plate material, and at least the see-through wall portion 2 and, if necessary, the non-see-through wall portion 3 are also made of a transparent plate material. In addition, for the non-see-through wall portion 3 of the sound insulation wall material 1, in addition to a transparent board material, an opaque board material can be used from the viewpoint of respecting privacy. From the viewpoint of improvement, a structure having an appropriate structure, such as one with a sound absorbing material added thereto, can be used.

できる。 On the other hand, as the rigid plate material used for the sound insulation wall material 1, plastic materials and glass materials are preferable. In particular, polycarbonate is used when impact resistance and workability are prioritized, and tempered glass is used when weather resistance is prioritized. or laminated glass can be suitably used.
次に、このようにして構成されている本考案に
つき、交通路Ｒを走行する走行体Ｃの時速が70Km
である場合を例に、その望ましい構造の遮音壁材
１の作用につき第１図を参酌して説明する。 Next, regarding the present invention configured in this way, the speed of the traveling body C traveling on the traffic road R is 70 km/h.
Taking the case as an example, the operation of the sound insulating wall material 1 having a desirable structure will be explained with reference to FIG.

なることから、運転者にとつて死角となり、直接
目に触れることがなくなる。 That is, the transparent wall portion 2 of the sound insulation wall material 1 installed on the running path R is at an angle θ 3 substantially perpendicular to the line of sight 11 at the left limit point of the driving visibility θ 1 of the traveling body C.
Since it is located in the same position and is transparent, the outside can be seen through without being affected by reflected light. In addition, since the non-see-through wall portion 3 extends perpendicularly to the see-through wall portion 2,
Since it is located substantially parallel to the line of sight 11, it becomes a blind spot for the driver and does not come into direct contact with the driver's eyes.

Not only can you get a sense of speed and speed, but you will not experience any abnormal psychological pressure, anxiety, or discomfort.

おそれを極力少なくすることができる。 On the other hand, the non-see-through wall portion 3 in the sound insulation wall material 1 is
Since it is not often visible to the driver's eyes, it should be made transparent like the see-through wall part 2, or it should be made opaque, or it may be coated with sound-absorbing material, etc., as appropriate. It is possible to install a structure with a more favorable soundproofing effect, and by increasing the degree of freedom in design, it minimizes the risk of negative effects such as sunlight and noise problems on the surrounding environment. be able to.
