DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be specifically described below with reference to the drawings.
1-3 is explanatory drawing which shows one Embodiment of the installation method of the vehicle stop column and the vehicle stop column concerning this invention. First, FIG. 1 is an explanatory view showing a cover material according to the present invention. As shown in FIG. 1A, the cover material 1 has a cylindrical shape and is formed using an elastic synthetic resin. A reflector 11 in which glass beads are attached to a band-shaped metal or synthetic resin is wound around the upper outer wall, or a reflector 11 formed by directly embedding a bead-like reflector is attached. In addition, the visibility at night is improved by providing retroreflectivity by light rays of a vehicle headlamp or the like.
[0020]
The AA sectional view of the cover material 1 shown in FIG. The cover member 1 is closed at the upper end and has a hollow portion 12 into which the core column can be inserted from the lower end. A hollow portion 12 is provided at the upper end of the hollow portion 12. If the upper end of the core pillar is fitted in the recess 13, the periphery of the recess 13 functions as the upper spacer 41 in the upper part of the core pillar. A lower spacer 42 is provided at the lower part so as to protrude from the inner peripheral surface of the cover material 1 toward the inside.
[0021]
Here, the synthetic resin having elasticity used for molding the cover material 1 is not particularly limited as long as it has elasticity. Natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, Elastic materials made of various synthetic rubbers and synthetic resins such as butyl rubber, ethylene propylene terpolymer, urethane resin, polyisobutylene resin, polyethylene resin, ethylene vinyl acetate copolymer, silicon resin, soft and hard vinyl chloride resin, elastomer, etc. A foam or the like may be appropriately used in consideration of molding conditions and the like. Further, recycled materials such as waste tires and factory waste materials and those obtained by processing them into chips may be used.
[0022]
As shown in FIG. 2, the cover member 1 is covered with a core column 2 erected on a road surface to form a vehicle stop column 10. First, with respect to a), the core column 2 is inserted through the hollow portion 12 from the lower end of the cover material 1. The inner diameter of the hollow portion 12 of the cover material 1 is made larger than the outer diameter of the outer peripheral surface of the core column 2, and when the cover material 1 is put on the core column 2, the cover material 1 covers the entire core column 2. As shown in (b), a space 3 is provided between the inner surface of the cover material 1 and the outer peripheral surface of the core column 2. Further, a screw or the like may be screwed to the core pillar 2 through the lower spacer 42 of the cover material 1 to fix the lower spacer 42 to the core pillar 2.
[0023]
Here, the core column 2 is not particularly limited. If the core column 2 is formed of a strong material such as a metal such as steel, aluminum, and stainless steel, concrete, or a main stone, the force to physically prevent the vehicle from entering is large. Larger and preferable. Such a strong material generally has a high surface hardness, and if a pedestrian collides, the pedestrian may feel more pain and injury. However, covering the cover material 1 reduces the degree of the pain and injury. The effect to do can be made larger. Further, the core pillar 2 may be erected on the road surface with the cover material 1 covered, but if the core pillar 2 previously erected on the road surface is covered with the cover material 1, it is already present around the road. It is possible to form the car stop column 10 using the core column 2. Furthermore, if the core pillar 2 is a pillar that formed a guard rail, a street fence, a railing, etc., these are mainly strong components made mainly of metal and concrete, and physically block the entry of vehicles. It is preferable because it has a large force to be used and also leads to the reuse of the columns.
[0024]
2A) is a cross-sectional view taken along the line AA in FIG. 3, and the one near the upper end is a) and the one near the lower end is b). As shown in (b), a space 3 is provided between the outer peripheral surface of the core column 2 and the cover material 1, but the upper end of the core column 2 is provided at the upper end of the hollow portion 12 of the cover material 1. It is fitted in the recess 13. Further, as shown in (b), a lower spacer 42 is integrally provided in the vicinity of the lower end of the cover member 1 so as to sandwich the outer peripheral surface in the vicinity of the road surface of the core pillar 2.
[0025]
Since the upper spacer 41 and the lower spacer 42 on the cover material 1 are provided, the cover material 1 placed on the core column 2 has no gap near the upper end and the lower end, thereby preventing the cover material 1 from shaking. It is possible to eliminate such a problem that the vehicle stop column 10 appears to be tilted due to the position shift. Further, the space portion 3 can be secured between the upper spacer 41 and the lower spacer 42 of the cover material, and it is possible to reduce the loss of the shock absorbing property of the vehicle stopper column 10.
[0026]
1 to 3, according to the vehicle stop column 10 in the present embodiment, the cover member 1 is simply covered on the core column 2, and the space portion 3 exists between the inner surface of the cover member 1 and the core column 2. Therefore, it is not necessary to provide the cover member 1 with a complicated cross-sectional shape in order to provide a mechanism for reducing the impact, and therefore the cover member 1 can be easily formed. Further, the combination of the synthetic resin having elasticity and the space portion 3 enables not only a strong impact such as a vehicle collision but also a weak impact such as a pedestrian collision. Pain and injury to pedestrians can be reduced even in the event of a collision.
[0027]
In the present embodiment, the cover member 1 may be provided with air pressure adjusting means for adjusting the air pressure in the space 3. In the case where the space 3 is sealed, since the air is simply compressed when an impact is applied, the impact cannot be expected to be reduced so much. If the air in the space 3 is excessively removed, the impact cannot be reduced if the elasticity of the cover material 1 is small. By adjusting the air pressure of the space portion 3 by the adjusting means, it is possible to set the impact absorbing power with a degree corresponding to the assumed impact.
[0028]
It is preferable that the air pressure adjusting means is provided by a method of providing an air passage from the space portion 3 to the outside air and regulating the passage, and a through-hole from the space portion 3 to the outside air is formed in a part of the cover material 1. The diameter of the hole may be adjusted or a valve may be attached to the hole, or the size of the gap between the cover material 1 and the core pillar 2 may be set. It may be formed from a shaped material and allow air to pass through voids remaining after molding.
[0029]
Further, by forming the vehicle stopper column 10 by the method according to the present embodiment, the cover member 1 is simply covered on the core column 2, and the space portion 3 exists between the inner surface of the cover member 1 and the outer peripheral surface of the core column 2. Therefore, the vehicle stop strut 10 having a shock absorbing function can be easily formed. Further, when the cover material 1 is placed on the core pillar 2, the space serving as the space portion 3 for absorbing the shock is sufficient, and the portion that becomes resistance when covered is the portion of the lower spacer 42, without using a lubricant or the like. The cover material 1 can be covered and the formation of the car stopper column 10 can be easy.
[0030]
Moreover, even if the core pillar 2 is an existing one, it is easy to form the stop post 10, so that metal or concrete facilities such as guardrails, street fences, railings, etc. are removed due to changes in road conditions. In this case, it is possible to cover the cover material 1 without removing the support column to form the vehicle stop column 10 and to recycle the support column, and to harmonize the design of the cover material 1 with the surrounding landscape. It is also possible to improve the maintenance of the landscape.
[0031]
4 and 5 show another embodiment according to the present invention, and are explanatory views showing another example of the lower spacer 42 of the cover material 1. First, as shown in FIG. 4A, a mounting bracket is attached as a lower spacer 42 near the road surface of the core column 2 as shown in FIG. The lower spacer 42 is wound around the core pillar 2 and fixed with bolts 421 as shown in FIG. By forming a through hole in the lower spacer 42 or providing a gap with the core column 2, the air pressure adjusting means may be used.
[0032]
FIG. 5 is a cross-sectional view showing the vicinity of the road surface of the vehicle stop column 10 formed by covering the core column 2 and the lower spacer 42 with the cover material 1. The inner surface of the cover member 1 is brought into contact with the outer surface of the lower spacer 42, and the cover member 1 and the lower spacer 42 are fixed by screws 5, so that the cover member 1 is connected to the core pillar via the lower spacer 42. 2 is fixed. The lower spacer 42 is provided in the vicinity of the road surface where it is difficult to feel pain when a pedestrian collides.
[0033]
By covering the core material 2 with the cover material 1 via the lower spacer 42, the hollow portion 12 of the cover material 1 can be made into a simple cylindrical shape, which facilitates molding and forms the cover material 1 longer. In addition, it is possible to easily cope with various lengths of the core column 2 by cutting the lower end and adjusting the length. Since the cover material 1 is formed of a synthetic resin, the cutting is easy.
[0034]
【The invention's effect】
According to the vehicle stopper strut according to the present invention, a space portion exists between the inner surface of the cover material and at least the outer peripheral surface of the core column only by covering the core column with the cover column. However, the cover material does not need to have a complicated cross-sectional shape, and therefore the cover material can be easily formed.
[0035]
According to the method for installing the vehicle stopper strut according to the present invention, since the space portion exists between the inner surface of the cover material and at least the outer peripheral surface of the core column only by covering the cover material on the core column, the function of absorbing shock It is possible to easily form a vehicle stop strut provided with Further, when the cover material is put on the core column, the space portion becomes roomy, and the formation of the vehicle stopper column can be facilitated.
