Abstract

PURPOSE:To obviate the change of plants and simplify the cleaning work by sticking branches having at least plastic leaves to a natural or plastic trunk so as to constitute artificial trees. CONSTITUTION:A dead tree is used for a trunk 2, for example, and branches 3, which are made of polycarbonate and to which many artificial leaves 4 made of polypropylene are stuck, are inserted in the trunk 2 and fixed to it. In addition, the branches 3 and leaves 4 are colored into nearly same colors as those of natural trees, or fluorescent coating is applied to the branches 3 and leaves 4. These artificial trees installed on the central partition belts provide beauties and light shielding effects, and replacing natural trees with artificial trees made of plastics prevents the shedding and dieing. Therefore, the change of plants is eliminated, and the cleaning work can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shield for use in a median strip of an expressway.

[Prior Art] Traditionally, natural trees have been planted as median strips on expressways. This is to make the center line clear and prevent head-on collisions, and to block the lights of oncoming vehicles at night.

In addition, simple fences and shelves are also used solely from the viewpoint of accident prevention.

However, usually, evergreen trees with a height of about 1 m to 1.5 m are often used. For example, Tsutsushi etc.

[Problem to be solved by the invention] Conventional natural trees have the following drawbacks.

In areas and seasons where roads freeze at night, salts such as Thangcal (calcium carbonate) are often sprayed on the road surface to prevent roads from freezing. This salt is released by car tires.
The particles were scattered and attached to the leaves and branches of trees, causing them to die. Even with this knowledge, salt is still being sprayed to prevent slips and accidents caused by freezing. Of course, it is impossible to clean and remove adhered salts due to labor costs.

Therefore, the dead trees will need to be replanted, but since the area is located in the center of the expressway, the construction work will not be easy. In other words, the road must be blocked off or made one-sided, which is not an easy task.

It goes without saying that there are dangers involved when making one-way traffic possible.

Furthermore, in the case of natural trees, fallen leaves inevitably occur, which makes roads messy. It is also difficult to clean this.

It goes without saying that trees will continue to grow as long as they are living things. Therefore, if the tree grows tall and there is a part of the trunk without leaves at the bottom, the effect of shielding the headlights of oncoming cars will be reduced.

Since it is used on expressways, it constantly inhales large amounts of automobile exhaust gas, so it also has the disadvantage that only trees that can withstand the exhaust gas can be used. Therefore, there is a desire to plant more aesthetically pleasing trees,
Even if there is a desire to plant locally famous trees, in many cases this is not possible.

To overcome this problem, some roads are simply constructed with walls. However, this is not aesthetically pleasing and may destroy the local landscape, making it difficult to use, especially in tourist areas. Furthermore, it is not good for the driver's mental health because it makes the driver feel like he or she is trapped in a small space.

Therefore, there has been a long-awaited desire in the industry for a shield that does not have the above-mentioned drawbacks.

[Means for Solving the Problems] In view of the above-mentioned current situation, the present inventor has completed the present invention shielding body as a result of intensive research. The artificial tree consists of a trunk made of natural or plastic and branches having at least plastic leaves attached to it.

Expressways as used herein include national expressways and automobile-only roads as defined in the Road Traffic Act.

A median strip separates oncoming traffic lanes.

Artificial trees are the subject of the present invention and have at least a trunk, branches and leaves. The trunk can be cut from a natural tree or molded into a plastic shape (120 colors).Plasti-Tsuku branches are inserted into this and fixed.
It forms like a natural tree. Also, attach plastic leaves to the branches. Of course, not only leaves but also flowers and fruits can be attached to the branches.

The plastic material may be any type of material, such as polyolefin such as polyethylene, polyvinyl chloride, etc.
Since it will be exposed to direct sunlight and wind and rain, it is desirable to use one with excellent weather resistance. For example, polycarbonate, polyester, etc.

Branches, leaves, etc. are naturally colored in colors similar to those of natural trees.

Furthermore, the artificial tree of the present invention may be coated with a fluorescent paint. This is to make the median strip clearer at night, to prevent collisions with it, and to give it a neon-like appearance.

Furthermore, you can proactively install lighting equipment to make it even brighter. For example, the branches can be equipped with colored light bulbs. Natural trees will die from the heat from the light bulb, but there is no problem if they are made of plastic. It is also possible to run the cord inside the trunk or branches.

The height of the artificial tree is free, but it may be the same as that of natural trees used for normal median strips, and the width and size of each tree is also free.

The shield of the present invention can be used as a median strip by itself, but it can also be used in conjunction with a step or a shelf made of steel to prevent cars from entering oncoming lanes. Good too.

[Example] FIG. 1 is a perspective view showing an example of the artificial tree 1 of the present invention. A dead tree is used as the trunk 2, and polycarbonate branches 3 are inserted and fixed thereto. A large number of leaves 4 made of polypropylene are fixed to this branch 3. The fixing method may be any method such as adhesion or fusion. Naturally, the colors are the same as natural trees.

FIG. 2 is a perspective view showing the example shown in FIG. 1 applied to a median strip of an expressway. A #jJ6 made of steel is provided in the center of the median strip 5 to prevent cars from protruding. Artificial trees 1 are provided on both sides of the fence 6. This creates an aesthetic appearance and a light shielding effect. Of course, there is no need for a central fence, and artificial trees may be planted in a row in the center.

■ Also, there are no fallen leaves, making cleaning easier.

■ Since it does not grow, there is no need to adjust its length or height.

■ It is possible to apply fluorescent paint or attach lighting equipment, which helps prevent accidents.

■ Since it is not a natural tree, there is no need for soil and roads will not get dirty.

■ Since there are no problems with exhaust gas, any type of tree can be used to match the surrounding landscape.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing an example of the present invention, and FIG. 2 is a perspective view showing the present invention in use. [Effects of the Invention] The shielding body of the present invention has the following advantages. ■ Since it is made of plastic, it will not wither and there is no need to repot it. 1...
