Description

도로용 가드레일 구조{GUARDRAIL STRUCTURE FOR ROAD}Road guardrail structure {GUARDRAIL STRUCTURE FOR ROAD}

본 고안은, 도로용 가드레일에 관한 것으로서, 더욱 상세하게는 차량과 충돌시 가드레일의 파손 및 전도 현상을 최소화할 수 있어 대형 사고를 미연에 방지하도록 개발된 도로용 가드레일 구조에 관한 것이다.The present invention relates to a road guardrail, and more particularly, to a road guardrail structure developed to prevent a large accident in advance by minimizing damage and fall of the guardrail when colliding with a vehicle.

일반적으로 도로의 일측 또는 양측에는 다양한 종류의 시설물이 설치되는데, 대부분의 도로에는 콘크리트를 이용한 시설 또는 아연도 강판을 이용한 가드레일이 설치된다.In general, various types of facilities are installed on one side or both sides of the road, and most roads are equipped with a facility using concrete or a guard rail using galvanized steel.

이러한 시설물, 특히 가드레일은 곡선 도로에 설치되어 차량의 추락을 예방함은 물론, 직선 도로에 설치되어 차량의 추락을 예방하게 된다.These facilities, in particular the guardrail is installed on a curved road to prevent the fall of the vehicle, as well as installed on a straight road to prevent the fall of the vehicle.

도 1은 종래의 가드레일과 차량과 충돌되는 상태를 나타내는 도면으로서, 방호책 지주(10)에는, 도로 중앙을 행해 날개형 방호책(30)이 체결 볼트(20)로 체결된 구조로 가드레일(50)이 설치된다.1 is a view showing a state in which a conventional guard rail and the vehicle collides, the guard rail (10), the guard rail (50) in a structure in which the wing-shaped guard fence 30 is fastened with a fastening bolt 20 through the center of the road ) Is installed.

상기 가드레일(50)은, 차량(60)과 충돌시 별도의 충격흡수 시설이 설치되지 않아 도시된 도면과 같이 가드레일(50)이 파손되거나 전도되어 차량이 도로를 이탈하여 대형 사고가 발생되는 문제점이 있다.The guard rail 50, when a collision with the vehicle 60 is not provided with a separate shock absorbing facility, as shown in the figure, the guard rail 50 is broken or conducted as the vehicle is off the road to cause a large accident There is a problem.

또한, 도면에서는 설명하지 않았지만, 가드레일(50)에 충격흡수 시설을 설치하여 도로 시설물로 이용하는 경우에도, 그 충격흡수 시설이 제대로 작동되지 않아 충격을 흡수하지 못하는 문제점을 갖는 경우가 많았다.In addition, although not illustrated in the drawings, even when a shock absorbing facility is installed on the guard rail 50 to be used as a road facility, the shock absorbing facility does not operate properly, and thus there are many cases in which a shock cannot be absorbed.

본 고안은 상술한 문제점을 감안하여 안출된 것으로, 본 고안은, 차량과 충돌시 가드레일의 파손 및 전도 현상을 최소화할 수 있도록 날개형 가드레일의 전,후방에 충격을 흡수할 수 있는 전방 충격흡수재 및 후방 충격흡수재가 설치되고,가로 보강재를 사용하여 날개형 방호책을 고정하는 새롭게 개발된 도로용 가드레일 구조를 제공함을 그 목적으로 한다.The present invention is conceived in view of the above-described problems, the present invention, the front impact that can absorb the shock to the front and rear of the wing-type guard rail to minimize the damage and fall of the guard rail when colliding with the vehicle It is an object of the present invention to provide a newly developed road guardrail structure in which an absorber and a rear shock absorber are installed and a wing reinforcement is fixed using a horizontal reinforcement.

상기 가로 보강재(240)는, I형 형태로, 이탈 방지틀(220)의 내측에 삽입된 후방 충격 흡수재(230)의 전방측에 삽입되는 한편, 상기 가로 보강재(240)는 아연도 강판을 이용하여 제작하여 사용할 수 있다.The horizontal reinforcement member 240 is inserted into the front side of the rear shock absorber 230 inserted into the release prevention frame 220 in the form of I, while the horizontal reinforcement member 240 uses a galvanized steel sheet. Can be manufactured and used.

상기 체결 볼트(250)(250)는, 날개형 방호책(260)을 방호책 지주(210)에 고정하는 체결 볼트(250)와, 날개형 방호책(260)의 돌출부(262)에 전방 충격 흡수재(270)를 고정하는 체결 볼트(250')가 사용된다.The fastening bolts 250 and 250 are fastening bolts 250 for fixing the wing-shaped protection fence 260 to the guard fence support 210, and the front shock absorbing material 270 to the protrusion 262 of the wing-shaped protection fence 260. Fastening bolt 250 'is used.

상기 날개형 방호책(260)은, 격자형 구조물로, 내측으로 절곡된 정중앙에 다수개의 볼트홀(261)이 형성되고, 그 정중앙을 기준으로 양측에 돌출된 위치에 돌출부(262)가 형성되며, 그 돌출부(262)에 볼트홀(263)이 형성된다.The wing-shaped protection 260 is a lattice structure, a plurality of bolt holes 261 is formed in the center of the bending bent inward, the protrusion 262 is formed at a position protruding on both sides with respect to the center of the center, A bolt hole 263 is formed in the protrusion 262.

즉, 상기 날개형 방호책(260)은, 중앙의 볼트홀(261)에 체결 볼트(250)가 관통되어 방호책 지주(210)에 결합된다.That is, the wing-shaped protection fence 260, the fastening bolt 250 penetrates through the bolt hole 261 in the center is coupled to the guard fence support 210.

상기 전방 충격 흡수재(270)는, U자형 형태로, 양측에 다수개의 관통홀(272)이 형성되어 날개형 방호책(260)의 돌출부(262)에 삽입되어 체결 볼트(250')로 고정된다.The front shock absorber 270 has a U-shape, and a plurality of through holes 272 are formed at both sides thereof and inserted into the protrusion 262 of the wing-shaped protection 260 to be fastened by a fastening bolt 250 ′.

상술한 가드레일(200)은, 방호책 지주(210)의 상부 일측에 고정된 이탈 방지틀(220)에 후방 충격 흡수재(230)가 설치되고, 날개형 방호책(260)의 돌출부(262)에 전방 충격 흡수재(270)가 설치되는 관계로, 외부 충격력을 전방 충격 흡수재(270)와 후방 충격 흡수재(230) 순으로 흡수하게 되므로, 날개형 방호책(260)과 방호책 지주(210)의 파손을 예방할 수 있음은 물론, 대형의 추돌 사고에 의하여 가드레일(200)이 파손되는 경우, 방호책 지주(210), 후방 충격 흡수재(230), 가로 보강재(240), 체결 볼트(250)(250'), 날개형 방호책(260) 및 전방 충격 흡수재(270)를 간단하게 교체할 수 있는 장점을 갖는다.In the above-described guard rail 200, the rear shock absorber 230 is installed on the release prevention frame 220 fixed to the upper side of the guard fence support 210, the front of the projection 262 of the wing-shaped guard fence 260 Since the shock absorber 270 is installed, the external shock force is absorbed in the order of the front shock absorber 270 and the rear shock absorber 230, thereby preventing damage to the wing-shaped protection measure 260 and the protection guard strut 210. Of course, if the guard rail 200 is damaged by a large collision accident, the guard fence 210, the rear shock absorber 230, the horizontal reinforcement 240, fastening bolts 250 (250 '), wings The mold protection 260 and the front shock absorber 270 can be easily replaced.

상술한 가드레일의 구성에 의한 효과를 설명한다.The effect by the structure of the guardrail mentioned above is demonstrated.

본 고안의 가드레일은, 날개형 방호책의 전방과 후방에 각각 전방 충격 흡수재와 후방 충격 흡수재가 설치되는 관계로, 외부의 충격력을 전방 충격 흡수재와 후방 충격 흡수재에서 순차적으로 흡수하게 되므로 가드레일의 파손을 최소화할 수 있는 효과를 얻을 수 있다.The guardrail of the present invention has a front shock absorber and a rear shock absorber respectively installed at the front and the rear of the wing protection, so that the external shock force is sequentially absorbed by the front shock absorber and the rear shock absorber, so that the guard rail is damaged. The effect can be minimized.

또한, 상기 가드레일은 대형의 추돌 사고에 의하여 가드레일(200)이 파손되는 경우, 방호책 지주, 후방 충격 흡수재, 가로 보강재, 체결 볼트, 날개형 방호책 및 전방 충격 흡수재를 간단하게 교체할 수 있는 효과를 얻을 수 있다.In addition, when the guard rail 200 is damaged due to a large collision accident, the guard rail is an effect that can easily replace the guard fence, the rear shock absorber, the horizontal reinforcement, the fastening bolt, the wing-shaped protective shield and the front shock absorber. Can be obtained.
