DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield used for a median strip such as a highway. In addition, the shield for the median strip here is not limited to the one used for the median strip, which is generally used, and is located at the center of the road like the shield for the median strip, for example, for protection of the lower part of the pier. Including guard blocks for toll booths and concrete at the toll booths, and also includes guard concrete walls located on the side of the road but within the driver's view and limiting the width of traffic, and elevated concrete walls of bridges It is.

[0002]

2. Description of the Related Art Heretofore, as a shield used for a median strip such as a highway, a fence-shaped shield and a natural tree have been used. The purpose of the shield is to clarify the center line, prevent head-on collisions, and block the lights of oncoming vehicles at night. Of these, the fences are fences made of concrete or metal, and in the case of natural trees, they are densely planted in fences. Its height is often about 1 to 2 m.

[0003]

The appearance of a fence made of concrete or the like (fence-shaped body) is poor, especially on a highway that passes through a region with excellent local scenery. Become. In addition, it causes the driver to feel as if he / she is trapped in a narrow place, which is not preferable for mental health. Driving over long distances can be very boring, drowsy and dangerous.

[0004] In addition, even the method of juxtaposing natural trees has the following disadvantages. In areas and seasons when the road freezes at night, salts such as calcium chloride are often sprayed on the road surface to prevent the road from freezing. These salts were scattered by the tires of the automobile and attached to the leaves and branches of the trees, causing the trees to die. Even if you know this,
From the viewpoint of preventing slip accidents due to freezing, salt is sprayed. Of course, it is impossible to clean and remove the attached salt due to labor cost. They often die for other reasons.

[0005] Therefore, the dead trees are replanted, but the construction is not easy because of the central part of the highway. That is, the road must be blocked or one-sided, which is not easy. It is natural that there is a danger when one-way traffic is used.

Furthermore, in the case of natural trees, the leaves are inevitably fallen, and the road becomes messy. Cleaning this is also a tough task. It goes without saying that trees grow as long as they are creatures. Therefore, when the back is elongated and only the trunk without leaves is formed at the lower portion, the shielding effect of the lights and the like of the oncoming vehicle is reduced.

[0007] Since it is mainly used on highways, since it inhales a large amount of exhaust gas from automobiles constantly, there is a disadvantage that only trees that can withstand the exhaust gas can be used. Therefore, even if there is a desire to plant a more beautiful tree in terms of landscape, or a desire to plant a locally famous tree, it is often impossible to do so. Therefore, there has been a long-awaited demand in the industry for a shield having no such disadvantages.

[0008]

In view of the above situation, the present inventor has completed the shield of the present invention as a result of intensive studies, and the feature of the present invention is that it has a central separation such as a highway. It is used for a band, and is composed of a main body and a cover that covers the main body. The main body is erected on the median strip, and the cover is a film-like body and has a surface. There is a point that artificial plants are stuck to the plant.

The expressways and the like referred to here are not only the expressway national roads and motorways described in the Road Traffic Act, but also expressways.
It also includes general roads. That is, it can be used anywhere where a shield is provided in the median strip of the road.

The median strip is a portion that separates and separates the oncoming lane.

The main body is provided upright on the median strip and is made of concrete, metal, FRP, hollow lightweight concrete containing steel, or the like. The height and thickness of the shielding body of the present invention are determined by this main body, and this is also a part to be called a core. The main body does not need to be special, and may be the above-mentioned conventional wall-shaped body or the like. In addition, an existing fence can be used for this. The shape of this main body is not only fenced, but also conical,
Any shape such as a cylindrical shape may be used. The standing method may be any method, and a normal construction method may be used. Further, in addition to the connection or integration to form a long fence, individual objects may be erected with or without a gap.

Further, in the case of metal, not only a usual fence-shaped one but also a type having only a metal frame may be used. These are very simple to build and inexpensive.

The main body may be manufactured at the median strip of the road. Of course, the above-mentioned cones and the like may be made of metal or concrete, but may be formed as a molded product at a factory.
You may install what was manufactured by mass production. This is better in terms of the construction period.

The cover portion is used to cover the main body portion, and may be any film-like material such as a sheet-like material or a net-like material. In short, any material may be used as long as it is flexible and can be covered along the main body. Woven fabrics and plastic sheets having weather resistance are suitable. In addition, a certain strength is required because it is necessary to avoid being broken by the wind or the like and flying away. It is necessary that this cover part be detachably and firmly fixed to the main body part.
The method of fixation is free, but tying with eyelets,
It is convenient to fix with bolts and nuts.

The cover does not need to cover the entire body, but may be partial. For example, it may cover only one side. Two sides may be used to cover both sides. This one-sided one is easy to wind up and easy to construct. Further, a plurality of main units may be covered by one cover unit.

[0016] Further, if it is made partial, it is easy to partially replace it, and it is easy to deal with damage, fading and the like.

If the cover is of a net shape and the main body is of a fence shape, there is also an effect that the facing portion can be seen. In the case of a net-like material, since the wind passes, separation due to wind pressure can be reduced.

The artificial plant is the subject of the present invention,
It does not need to be the whole plant, but may be only leaves or flowers. These plants are artificially produced,
The plastic used as the material may be any material such as polyolefin such as polyethylene and polyvinyl chloride.
Because of being exposed to direct sunlight and wind and rain, those having excellent weather resistance are desirable. For example, polycarbonate, polyester and the like. Branches and leaves are naturally colored to a color close to a natural tree. The production of this plastic plant is well-known in the usual way and without any limitations.

In the case of an entire tree having a trunk, branches and leaves, a branch formed by fixing a large number of leaves is inserted and fixed in a plastic trunk to form a natural tree. Of course, not only leaves but also flowers and fruits can be fixed to the branches.

The artificial plant is firmly fixed to the cover. The fixing method may be any method such as fusing or bonding. It must be firmly fixed so that it does not separate by wind or the like. It is also because the object of the present invention is that leaf fall does not occur. Only the leaves may be adhered to the cover to form a planar pattern, or a part of the branch or trunk may be fixed to form a three-dimensional pattern. When applied three-dimensionally, it is necessary to adhere more firmly because there are few fixed parts.

Further, the artificial plant of the present invention may be coated with a fluorescent paint. This is to clarify the median strip at night, prevent collision with them, and obtain a neon-like aesthetic. Furthermore, in order to make it brighter, a lighting fixture can be positively attached. For example, a colored light bulb or the like is provided on a branch. In the case of a natural tree, it will die due to the heat of the light bulb, but there is no problem if it is made of plastic. It is also possible to pass the cord inside the trunk or branch.

The size of the artificial plant is not limited, but may be the same as that of a natural tree used in a usual median strip.
However, they can be larger than natural products or have a distinct color for better visibility from a distance.
