〔産業上の利用分野〕
本発明は、対面2車線道路用の中央分離帯、特に、対面
2車線であるが規制速度を70Km/Hとした対面2車

関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a median strip for two-lane roads, particularly for two-lane expressways with two lanes on each side but with a speed limit of 70 km/h. The present invention relates to a method of configuring a median strip and an apparatus therefor.
〔従来の技術〕

配列設置している。[Prior Art] Some roads with two facing lanes are provided with a center separation 41F to prevent a running vehicle from crossing the center line and running out into the oncoming lane. Conventional median strips are made of light metal chatter bars, concrete blocks, etc., arranged in an array using anchor bolts.
しかし乍ら、チャッターバーは、雨や雪などで表面がぬ
れると滑りやすくなり、特に、舗装面から脱出すると非
常に危険であって、対面2車線道路には好ましくない。However, the chatter bar becomes slippery when its surface becomes wet due to rain or snow, and is particularly dangerous if it escapes from the paved surface, making it undesirable for two-lane roads.
前記の如き従来の中央分離帯は、何れも硬質材で構威さ

来の中央分離帯は、前記の如きブロックなどであるので
、車輌が乗り越えやすいという問題がある。All of the conventional median strips mentioned above are made of hard materials, so when a vehicle comes into contact with or collides with them, the strong shock and vibration that occurs at that moment is transmitted to the steering wheel. The handle may be taken off. Furthermore, since conventional median strips are made of blocks as described above, there is a problem in that vehicles can easily cross over them.

路が認められて来た。-3 On the other hand, the speed limit on expressways is 80km/t {
Unless the speed limit of the two-way two-lane road connected to this expressway is increased, its value as an expressway will decline, so an expressway with two two-way lanes but with a speed limit of 70km/l has been approved.

行中万一タイヤが中央分離帯に接触ないし衝突したとき
には、その瞬間に発生する強力な運動エネルギーによっ
てハンドルが取られないようにすることが望まれる。When the speed limit is set to 70 km/h, it is desired that the median strip of a two-lane road has a function different from the conventional one. In other words, the median strip on a two-lane expressway does not make drivers feel uneasy while driving, provides clear line-of-sight guidance, and provides reliable guidance. When a vehicle contacts or collides with a median strip, it is desirable to prevent the steering wheel from being taken off by the powerful kinetic energy generated at that moment.
本発明は、前記の如き70Km/ITなどの対面2本線
高速道路用の中央分離帯として好適な中央分離帯の構成
方法およびその装置を提供することを目的とする。An object of the present invention is to provide a method and apparatus for configuring a median strip suitable for use as a median strip for a two-way two-way expressway such as the above-mentioned 70 km/IT expressway.

At the same time, the kinetic energy is absorbed by plastic deformation when a vehicle tire contacts or collides between each upright sign and the upright sign.
A shock absorber with a low dispersion height of, for example, about 150 mm is laid along the center line, and the raised indicator guides the driver's line of sight and prevents the driver from receiving a shock when the vehicle's tires touch or collide. is absorbed and dispersed by the buffer.

車輌に与える衝撃を緩衝させることができる。Also, when a tire touches or collides with a shock absorber installed along the center line while driving, the shock absorber is plastically deformed and generates a powerful amount of kinetic energy. By absorbing and dispersing energy, it can buffer the impact on the vehicle.

Drill holes through the backing plate 43, 44 and the pipe at two locations near both ends of the washer 4 from inside the pipe.
The bolt 46 is inserted into the hole through the bolt 46 so that the tip of the bolt 46 protrudes outward.
Screw them together. Incidentally, a retroreflective sheet 49 in the shape of an arrow, for example, is adhered to the surface of the pipe 41.

and the screw hole of the buried leg 48, screw the bolt 46 into the buried leg 48 and tighten it, and then insert the hollow pipe 41.
A foamed foam 42 such as polyurethane foam is filled or foamed inside. Note that FIGS. 3 and 4 show an example in which expanded foam is formed in the hollow pipe 41, but for example, a plate-shaped expanded foam rolled into a cylindrical shape is placed in the hollow pipe 4l. It can also be inserted and filled.

とよりなるので,両者の色彩を次の如くすることにより
運転者に対して案内,警戒等の感覚を与え、安全運転に
資することができる。8. As mentioned above, the present invention consists of upright signs installed at appropriate intervals and buffers installed between each upright sign. It can provide a sense of guidance, caution, etc. to the driver and contribute to safe driving.

グレー地の緩衝体が敷設されているので、運転者に抵抗
感を与えず、また汚でもその汚れが目立たないという利
点がある。That is, the background color of the buffer is made gray, and the retroreflective sheet 49 provided on its surface is made yellow. Since the roadway is paved with asphalt, it is black, and a gray cushioning material is placed in the center, which has the advantage that it does not give drivers a sense of resistance, and even if it gets dirty, it is not noticeable.
これに対し、起立標示体は、その地色がグリーン系など

の起立標示体を敷設する。On the other hand, stand-up signs are prepared in at least two types, one with a background color such as green that does not irritate the eyes, and one with a background color such as red that is irritating to the eyes. The main part of the installation will be upright signs with a ground color that does not give any irritation to the eyes, but upright signs with a ground color that will irritate the eyes will be installed over a certain section.
例えば、グリーン系の地色の起立標示体を2Kmにわた

系は目に刺激を与えないので安全感を与え、その状態が
あまり長く続くとたいくつするので、次の100m間を
レッド系にし、目に刺激を与えて気付薬になるようにす
る。For example, stand-up signs with a green background color are laid for 2km, then stand-up signs with a red-base color are laid for 100m, and then green-type signs are laid again for the next 2km. If you do this, the green color will give you a sense of safety as it will not irritate your eyes, but if this condition continues for too long, you will feel tired, so for the next 100 meters, you will use the red color, which will irritate your eyes and give you a sense of safety. I will make it happen.
このように、緩衝体と起立標示体の色彩を組み合せるこ
とにより、道路自体にエレガントな感覚を付与させると
共に、運転者の神経を苛立たせることなく、安全運転に
資することができる。In this way, by combining the colors of the shock absorber and the upright sign, it is possible to give an elegant feeling to the road itself and contribute to safe driving without irritating the driver's nerves.
以上述へたように、本発明によれば、走行中の運転者に
対して鮮明な視線誘導を行なうと共に、車輌のタイヤが
センターラインに接触ないし衝突した際にはその衝撃を
吸収,分散させて安全運転に資することができる効果が
ある。As described above, according to the present invention, it is possible to clearly guide the driver's line of sight while driving, and also to absorb and disperse the impact when the tires of the vehicle contact or collide with the center line. This has the effect of contributing to safe driving.
