Safety barrier

Abstract

A safety barrier includes: a body installed on a road; a steel plate portion placed between the body and the road; and an anchor portion passing through the steel plate portion and having an upper part buried in the body and a lower part buried in the road, wherein a first space in which a middle part of the anchor portion other than the upper part and the lower part is placed, is formed between the body and the road, and when an impact is applied to the body, the body is moved while accompanying bending deformation of the middle part in the first space so that the impact is absorbed, and after bending deformation of the middle part occurs, the steel plate portion breaks the anchor portion to implement further movement of the body caused by the impact so that the impact is dispersed.

What is claimed is: 
     
         1 . A safety barrier comprising:
 a body installed on a road;   a steel plate portion placed between the body and the road; and   an anchor portion passing through the steel plate portion and having an upper part buried in the body and a lower part buried in the road,   wherein a first space, in which a middle part of the anchor portion other than the upper part and the lower part are placed, is formed between the body and the road, and   when an impact is applied to the body, the body is moved while accompanying bending deformation of the middle part in the first space so that the impact is absorbed, and   after bending deformationdeformation occurs in the middle part, the steel plate portion breaks the anchor portion to implement further movement of the body caused by the impact so that the impact is dispersed.   
     
     
         2 . The safety barrier of  claim 1 , wherein the first space is provided by the road and the body includes a second space in which the steel plate portion is placed at a lower part, and the steel plate portion is moved together with the body when the body moves as a result of the impact. 
     
     
         3 . The safety barrier of  claim 2 , wherein the steel plate portion covers the first space before the impact is applied to the body. 
     
     
         4 . The safety barrier of  claim 2 , further comprising a damage prevention portion placed at a lower side of the first space, defining the lower side of the first space and preventing damage of the road due to the lower part when bending deformation occurs in the middle part. 
     
     
         5 . The safety barrier of  claim 1 , wherein the first space is provided for the lower part of the body, and the steel plate portion is accommodated in a second space provided by the road and is implemented independently of movement of the body due to the impact. 
     
     
         6 . The safety barrier of  claim 5 , wherein the steel plate portion defines the lower side of the first space before the impact is applied to the body. 
     
     
         7 . The safety barrier of  claim 5 , further comprising a damage prevention portion placed at an upper side of the first space, defining the upper side of the first space and preventing damage of the body due to the upper part when bending deformation occurs in the middle part. 
     
     
         8 . The safety barrier of  claim 1 , further comprising a connector placed around the middle part, allowing the first space when at least one of the road and the body is formed, to be formed and allowing connection of the road and the connector after the road and the body are formed. 
     
     
         9 . The safety barrier of  claim 8 , wherein the connector is made of a material having a lower strength than a strength of at least one of the road and the body. 
     
     
         10 . The safety barrier of  claim 1 , wherein a plurality of first spaces are spaced apart from each other in a longitudinal direction of the body or are continuously formed in the longitudinal direction of the body. 
     
     
         11 . The safety barrier of  claim 1 , wherein the steel plate portion includes a through hole through which the anchor portion passes, and an inner surface, on which the through hole is defined, is inclined so that fracture of the anchor portion due to the steel plate portion is easily performed. 
     
     
         12 . The safety barrier of  claim 1 , wherein the steel plate portion includes a through hole through which the anchor portion passes, and a diameter of a portion of the anchor portion that corresponds to the through hole is relatively smaller than a diameter of the other portion of the anchor portion so that fracture of the anchor portion due to the steel plate portion is easily performed.
