An object of the present invention is to provide an elastic bollard for roads in which the body tube and the refraction recess are reduced in weight. It is to provide a bollard to strengthen the body tube assembly force.

The present invention will be described in detail with reference to the accompanying drawings.

The roadway elastic bollard of the present invention supports a body tube 20 at the upper portion of the ground support 30, and a tubular refraction recess 10 having a refractive motion and an elastic restoration operation; An assembly apparatus for attaching the refractive recess 10 to the upper portion of the ground support 30; An assembly device for attaching the body tube 20 to the upper portion of the refraction recess; The body tube 20 is composed of a refractive wrinkle 11 is installed around the refractive recess so that when the side pressure is given. The tubular refractive recess 10 is made of an elastic material having cold resistance, moisture resistance, and chemical resistance. Such materials are materials including synthetic rubber, vinyl, PVC, rubber, silicone and polyurethane.

The refractive action of this inventive bollard is given by the tubular refractive recess 10 made of an elastic material. When the vehicle impacts the side of the body tube 20, the refraction recess 10 is stably refracted as shown in Figs. As the bollard is refracted at the portion of the refraction recess 10, the impact is alleviated to reduce damage to the crash vehicle, and the amount of breakage of the bollard also decreases. When the impact pressure applied to the bollard side is released, the posture is restored to its original state by the elastic return force of the refraction recess 10. The refraction recess 10 is a polymer elastic corrugated tube having cold resistance, moisture resistance, and chemical resistance, so that a wide range of temperature changes according to seasons and weather conditions, and reliably operates at any time on a road in which the installation environment changes variously, such as during a snowfall. do. This invention bollard can be manufactured at low cost because the body tube 20 and the refraction recessed part 10 is the main part of the interior and the product is light.

The tube attachment device includes an annular groove (16) for coupling the body tube (20) of the upper main surface of the refractive recess (10); A hard inner tube member 17 inserted into the inner surface of the bent portion of the refractive recess 10 to impart body tube support force to the elastic tube member; The body tube 20 is attached to the bent portion of the body tube 20, and half-tightened by tightening with a screw 23. At the same time, the body tube 20 is inserted into the annular groove 16 in the assembled state. It consisted of the bisecting tie bands 21 and 22 which press-fix. The tie bands 21 and 22 are attached to the bent portion by insert injection during molding of the body tube 20 or to the bent portion of the body tube 20 by other attachment means. The tool insertion hole is installed on the outer surface of the body tube 20 to tighten the screw 23. When the two tie bands 21 and 22 attached to the bent portion of the body tube 20 are forcibly inserted into the annular groove 16, the bent portion of the body tube 20 is slightly inflated and then contracted. When the screw 23 is tightened, the half tie bands 21 and 22 are assembled into one and the diameter of the band is narrowed, and the hard inner tube 17 is in close contact with the bent portion of the refractive recess 10 so that the body tube 20 and the refractive recess ( 10) Connect firmly. In the embodiment, the hard inner tube 17 extends to a portion covering the upper end of the refractive recess 10. This extension keeps the coupling state of the inner tube 17 and the refraction recess 10 always correct. The screw 23 may be loosened and the body tube 20 may be separated from the refraction recess 10. In this way, the body tube 20 of the present invention is assembling the body tube 20 to the refraction recess 10 by the upper assembly device, and can only replace the body tube 20 when the body tube 20 is damaged.
