[0001] Prefabricated safety bollard [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated safety bollard capable of preventing entry of a vehicle or the like into a vehicle through which a pedestrian passes and securing the safety of the pedestrian in the event of an impact with a pedestrian, And a protective cover that is detachably attached to an outer side of the impact absorbing portion to prevent breakage of the impact absorbing portion and is provided with a restoring portion that is inclined at a predetermined angle when the pedestrian and the vehicle collide with the safety bollard .

Generally, a bollard is an obstacle installed on the boundary between a road and a road to prevent the entry of a vehicle into a road and a park, thereby securing the safety of a pedestrian. The bollard used for this purpose is usually produced by processing stone or by processing iron or synthetic resin.

The bollard used for this purpose was initially used as a stone bollard. Stone bollard has high strength but no impact absorption, frequent collision with blind people or pedestrians, frequent collision, collision with other vehicle or other external impact, And the bollard made of steel afterwards was able to shorten the production time by securing the low construction cost and the productivity, but there was a problem that the corrosion rate due to aging and the accident rate of the pedestrians falling down during the night shift were increased.

In addition, the bollard made of synthetic resin material has a tendency to be mass-produced, easy to install and install, and widely used, but it is easily broken due to external impact during winter, resulting in increased maintenance cost.

In order to solve such a problem, in recent years, the advantages of each of them have been combined, a column made of a metal material has been buried in the ground so as to protrude at a predetermined height, the lower end of the column is fixed to the ground, The cover is covered and a space is formed in the cushion cover so that when the human body hits it, it is bent so as not to be injured, thereby developing a shock absorbing bollard.

However, since the shock absorbing cover is made of a soft material and exposed to the outside, if a small impact or impact is applied, it tears or breaks, and therefore the entire shock absorbing cover can not be replaced, resulting in economic loss. And the reflective tape was easily detached from the surface of the buffer cover due to the influence of the climate.

Also, since the bottom of the conventional bollard is firmly fixed to the ground, when the vehicle or motorcycle collides with the bottom of the bollard, the bollard is drawn out from the ground, thereby damaging the sidewalk block and causing an economical loss. The problem that has been caused continuously.

Therefore, the impact absorbing member can be absorbed from the outside of the bollard as well as the durability can be improved because the impact absorbing member is not exposed to the outside, and it is formed in a prefabricated structure, so that the installation and construction method is easy. It is necessary to develop a prefabricated safety bollard that can prevent the bollard from being pulled out from the ground due to a tilted angle.
