[Prior Art]

 Stone columns, concrete columns, etc. are generally used as conventional structures for this type of partition.

Since these have great rigidity, they are easily broken or damaged when subjected to a large impact such as a rear-end collision of an automobile, and there is a risk of scattering fragments, and not only the damage on the automobile side is large. However, the operator also has a material defect that is harmful. In addition, even if a pedestrian hits the pedestrian, it is easily affected.

Further, since the color definition is inferior in terms of material, it is not only difficult to obtain an excellent marking effect, but also it is difficult to obtain a soft and harmonious color with the environment of the installation site. In addition, it is impossible and expensive to obtain the required color in the stone pillar.

In addition, the concrete column has a drawback that it is easily polluted at an early stage and has poor aesthetic retention. In addition, the columnar body made of these materials is heavy and difficult to handle during installation.

[Problems to be solved by the device]

 It is necessary to eliminate the material defect due to the large rigidity of the conventional example by a structure having sufficient shape retention and cushioning property.

[0007] In addition, a free and vivid color can be obtained for the pillar material itself, not a paint-like feeling, and a material with excellent marking properties can be easily obtained with a soft and harmonious color to the environment of the installation site. Therefore, it is necessary to have an excellent structure that can maintain its aesthetic appearance for a long time even under wind and rain.

In addition, there is a need to prevent the risk of breakage or scatter easily due to a rear-end collision of an automobile or the like. Furthermore, it is to obtain a configuration that is relatively lightweight, easy to install on the ground, and easy to replace.

Therefore, an object of the present invention is to provide a lightweight bogie post for a car stop, which is excellent in shape retention, cushioning property, free color and marking, and is excellent in safety. is there.

[0010]

[Means for Solving the Problems]

 As a result of exploration to achieve the above-mentioned object, the inventors found that all of the conventional defects can be achieved by constructing a columnar body composed of a three-layer combination of a shape-retaining inner column, a buffer layer, and an elastic outer column. It is a conclusion that can be resolved.

That is, a car-stop column according to the present invention comprises a hard hollow shape-retaining inner column made of a hard resin material or a metal, and a buffer layer made of a rubber-based or plastic-type buffer material covering the inner column. An elastic pillar for a car stop, which is composed of three layers of an elastic outer pillar made of an elastomer having a large toughness and covering the buffer layer, is excellent in shape retention and cushioning.

As the hard resin material forming the shape-retaining inner column, hard thermoplastic, thermosetting plastic, FRP (Fibrous glass Reinforced Plastics), FRTP (Fibrous glass Reinforced Thermoplastics, Fibrous-reinforced Thermoplastics) are used. it can. A rubber-like material or a composite of rubber and fiber can be used as the rubber-based cushioning material that constitutes the cushioning layer that covers this, and a plastic-based cushioning material is a cushioning material such as cushioning hard urethane foam. Hard plastic foam is used.

The elastic outer column is an elastic polymer material having excellent weather resistance and aging resistance, and an elastomer having high toughness is suitable. For example, EPT (ethylene / propylene / diene monomer terpolymer), polyurethane rubber or the like is used. Further, if a thin film of plastic such as polyvinyl chloride, polypropylene or polyethylene is integrally formed on the above elastomer, further water resistance and aging resistance can be obtained. The shape may be a round shape, a square shape, a polygonal shape, or the like, and various shapes can be formed as desired. In addition, the above-mentioned elastomers not only give free and vivid colors, but are colored by the composition, so it is possible to change the color and pattern such as the formation of a marble pattern using various colors. Further, the elastic outer column can be divided into a head, a lower part, and the like to give a color change, thereby giving a wider variety of marking properties.

[0014]

[Action]

 Unlike the conventional stone pillars and concrete pillars, the above-mentioned elastic pillars for bollards are assembled from shape-retaining inner pillars, buffer layers and elastic outer pillars, and have good shape-retaining properties as well as cushioning characteristics. It is rich.

Further, the elastic outer column is made of an elastomer having high toughness, and not only secures a high degree of safety without the risk of being easily broken or scattered, but also is effective for pedestrians. Also has a function as a safety pillar. In addition, it is possible to obtain a clear and colorful color as a standard pillar in terms of material, and there is no danger of being easily peeled off by hitting, impact, mischief, etc. like paint, and it is easy to create an aesthetic pillar that matches the environment and color of the installation site. Can be obtained. Moreover, it is possible to maintain the beauty without being contaminated for a long period of time. Moreover, since the buffer layer is provided between the shape-retaining inner column and the elastic outer column, it has a three-layer structure. Each can be easily implemented by utilizing the deformation of the buffer layer, and cannot be easily removed after the fitting due to the restoration of the buffer layer.

In addition, it is relatively lightweight as a whole and is easy to handle during installation.

[0017]

FIG. 1 shows an embodiment of an elastic post pillar for a car stop according to the present invention. The shape-preserving inner pillar 1, a buffer layer 2 covering the outer side of the inner pillar, and the buffer layer 2 are shown. It is composed of a three-layer combination with an elastic outer column 3 made of an elastomer having a large toughness that covers the outside of the.

The shape-retaining inner column 1 is configured as a hard hollow shape-retaining inner column made of FRP, and the buffer layer 2 is made of a cushioning hard urethane foam. Both of them are integrally bonded by heating at the time of molding, but they may be fitted and fixed. In this case, the structure can be easily fitted by utilizing the deformation of the buffer layer 2, and the structure is hard to come off after the fitting. Reference numeral 4 is a disc made of a hard resin material, which is adhered to the head of the shape-retaining inner column 1. When the shape-retaining inner pillar 1 is made of metal, this disc may also be made of metal. Needless to say, the upper surface of the disk may be covered with the buffer layer 2.

The elastic outer column 2 is fitted to the outer periphery of the buffer layer 2, but can be easily fitted by utilizing the deformation of the buffer layer 2, and after the fitting, the buffer layer is restored. It becomes difficult to come off. In addition, it is also possible to bond and fix by fitting through an adhesive.

Since the elastomer constituting the elastic outer column 2 is heat-cured from the compounding composition of the required color, the material itself can obtain a clear and vivid color. In the example shown in the figure, it is constructed as one body, but it is also possible to form it in a properly divided state, change the color of each, and fit and adhere it to the outer periphery of the buffer layer 2.

Reference numeral 5 denotes a flange portion that is formed at the same time when the shape-retaining inner pillar 1 is formed, and is embedded and fixed in the ground 6. However, as a fixing method, various methods such as forming a fitting projection or the like on the ground 6 and fitting and fixing the shape-retaining inner pillar 1 can be appropriately adopted as required. In addition, it can be fixed to a movable mounting base and used as an elastic pole post for a car stop that can be moved and used. Numeral 7 is a bolt hole for mounting an anchor bolt or the like which is used as necessary.

As the shape, the most general circular shape is shown as an example, but it can be formed into any shape as desired. Depending on the application, the appearance of the elastomeric elastic column is to increase the wall thickness at points where impact, contact, or other external forces act, and to make it functionally protruding or to improve the marking. The shape is changed, the fluorescent band is set, or the like.

In addition, a protective ring made of hard plastic or the like is provided along the outside of the elastic outer column near the part to be buried in the ground and the lower part to be embedded, and is transformed into a bonding part of the fixed fixing part with fixed cement. It is preferable to form a strong bonding portion between the protective ring and the cement, which is not deformed, so as to prevent the occurrence of the above phenomenon.

When the shape-retaining inner column 1 is made of metal, the flange portion 4 is also made of metal and is separately prepared and attached by welding or the like as shown in FIG.
