AI Technical Summary

Benefits of technology

The present invention is a safety barrier that can prevent cars from accidentally invading opposite lanes and minimize damage to cars and drivers in case of a collision. It also reduces the risk of driving on the opposite road and getting hit by car fragments.

Problems solved by technology

However, due to such characteristics, there is a problem in that the safety barrier according to the related art has a very large amount of impact applied as a consequence of a car that directly collides with the safety barrier.
This causes a driver to be seriously injured, and in some cases, may cause death.
Thus, protection of a colliding car is not suitably performed.
In addition, when a high load is instantaneously transferred to the safety barrier due to the car that collides with the safety barrier, fragments such as concrete occur.
These fragments may also cause an injury to a driver of a car that is driven on an opposite road.

first embodiment

[0061]FIG. 1 is a schematic perspective view of a safety barrier according to a first embodiment of the present invention, FIG. 2 is a schematic cross-sectional view of the safety barrier according to the first embodiment of the present invention, and FIG. 3 is a schematic cross-sectional view for explaining a deformed situation of when an external impact is applied to the safety barrier according to the first embodiment of the present invention.

[0062]Referring to FIGS. 1 through 3, a safety barrier 100 according to the first embodiment of the present invention may include a body 110 installed on a road L, an accommodation space 112 formed inside the body 110, and an anchor portion 120 installed to pass through the accommodation space 112. The body 110 may be installed between lanes of the road L on which a car is driven in both directions, and in the present embodiment, the body 110 may be made of concrete, for example.

[0063]Also, in the present embodiment, the body 110 is formed t...

second embodiment

[0086]FIG. 7 is a schematic cross-sectional view of a safety barrier according to a second embodiment of the present invention.

[0087]Referring to FIG. 7, a safety barrier 200 according to the second embodiment of the present invention has the same elements as those of the safety barrier 100 according to the first embodiment of the present invention described with reference to FIGS. 1 through 6 but is different from the safety barrier 100 according to the first embodiment of the present invention described with reference to FIGS. 1 through 6 in that an accommodation space 212 is formed not in a body 210 but in a road L.

[0088]In this way, even when the accommodation space 212 is formed in the road L, the external impact can be effectively dispersed through deformation of the anchor portion 220.

[0089]The accommodation space 212 may be formed in only one of the body 210 and the road L and may be also formed in both the body 210 and the road L.

third embodiment

[0090]FIG. 8 is a schematic cross-sectional view of a safety barrier according to a third embodiment of the present invention.

[0091]Referring to FIG. 8, a safety barrier 300 according to the third embodiment of the present invention is the same as the safety barrier 100 according to the first embodiment of the present invention described with reference to FIGS. 1 through 6 in that an accommodation space 312 is formed in a body 310 but is different from the safety barrier 100 according to the first embodiment of the present invention in that an auxiliary accommodation space 322 is formed in the road L.

[0092]The auxiliary accommodation space 322 may be formed at the other side of the body 310 and the road L in which the accommodation space 312 is not formed. The auxiliary accommodation space 322 forms a room space around the anchor portion 320 so as to allow displacement caused by strain of the anchor portion 320.

[0093]That is, the auxiliary accommodation space 322 increases a displac...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 2018-0062706, filed on May 31, 2018, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND1. Field of the Invention[0002]The present invention relates to a safety barrier installed on a road, and more particularly, to a safety barrier capable of promoting safety.2. Discussion of Related Art[0003]In general, a safety barrier is installed for the purpose of preventing collision between cars that move in opposite directions on a road on which a car is driven, in particular, an expressway on which high-speed driving is performed, or a vehicular road, for the purpose of preventing a vehicle that is driven in a wrong direction, from deviating from a road, entering an opposite lane, or the like, and for the purpose of minimizing a passenger's injury or damage of a vehicle.[0004]A safety barrier according to the related art is usua...
