본 발명은 탄성고무를 이용한 차량의 충격흡수 가드레일에 관한 것으로서, 특히 차량이 가드레일에 충돌시 가드레일을 탄성재질로 함으로써 운전자 또는 탑승자의 충격을 완화시키며 또한 차량이 가드레일에 충돌 후 도로로 튕겨져나가 후방에서 근접하는 차량과의 2차적인 충동사고를 방지하는 것에 관한 것이다.The present invention relates to a shock absorbing guard rail of a vehicle using elastic rubber, and in particular, when the vehicle collides with the guard rail, the guard rail is made of an elastic material to alleviate the impact of the driver or passenger, and the vehicle is bounced off the road after the collision with the guard rail. The present invention relates to preventing secondary impulse accidents with a vehicle approaching from behind.

일반적으로 고속도로 및 자동차 전용도로 등의 고속주행로 급커버길의 중앙차로와 갖길 등에는 자동차의 고속 주행시 운전자의 부주위(졸음운전, 운전미숙 등)로 인하여 중앙차로 넘어가거나 도로 밖으로 튕겨져나가는 것을 차단하기 위한 중앙분리대 및 가드레일 등이 설치된다. In general, high-speed driving lanes such as highways and car-only roads, such as the central lane of the rapid cover road, are blocked from passing over to the central car or being thrown out of the road due to the driver's sub-circumference (drowsy driving, immature driving, etc.) during high-speed driving of the vehicle. Central separator and guard rail for the purpose is installed.

이러한 중앙분리대 및 가드레일은 콘크리트 구조물 또는 철재 분리대 등으로 이루어져 있어, 자동차가 중앙차로를 넘어 반대편 차로로 넘어가는 것을 차단하거나, 도로 난간으로 떨어져 나가게 되는 것을 방지하여 운전자 및 탑승자의 생명을 보호하게 되는 것이다.The central separator and the guard rail are made of concrete structures or steel separators, which prevents the vehicle from crossing the central lane to the opposite lane or prevents the vehicle from falling off the road railing to protect the driver and the passenger. will be.

그러나, 이와 같은 종래 중앙 분리대 및 가드레일 등은 충돌시 자동차가 반대편 차로로 넘어가거나 도로 난간으로 떨어지는 것을 차단하게 되는 근본적인 역할을 수행할 수 있으나, 자체에 자동차 충격을 어느 정도 완충할 수 있는 수단이 마련되지 못하여 충격에너지가 자동차로 그대로 전달됨으로써 운전자 및 탑승자의 안전에 심각한 문제점이 발생하였다.However, such a conventional central separator and guard rail may play a fundamental role of preventing the vehicle from falling to the other lane or falling into the road railing in the event of a collision, but a means for cushioning the car shock to some extent may be provided. Since the shock energy was not delivered to the vehicle as it was not prepared, serious problems occurred for the safety of the driver and the occupant.

주지하다시피 경제적 규모의 확대 및 소득 증가로 인한 교통량의 급격한 팽창, 그리고 차량 성능 향상에 따른 도로 교통의 고속화로 교통사고가 날로 증가하고 있고, 교통 사고 형태도 대형화되어 막대한 국가 사회적 손실을 초래하고 있으며, 또한 교통사고 중 특히 차량 단독 사고가 통계상으로 급격한 증가추세에 있어 노변 시설물을 정비하고 엄격한 연구결과를 통하여 입증된 방호 구조물의 설치가 시급하게 요구되고 있다. 이러한 방호 구조물들 중 가장 대표적인 것이 가드레일 및 이 가드레일의 전방에 설치되는 도로용 차량충돌 충격흡수장치가 있다.As is well known, traffic accidents are increasing due to the rapid expansion of traffic volume due to the expansion of economic scale and income increase, and the speed of road traffic due to the improvement of vehicle performance. In addition, there is an urgent need for the maintenance of roadside facilities and the installation of protective structures proven through rigorous research, especially in the case of traffic accidents, especially vehicle accidents. The most representative of these protective structures is a guard rail and a road vehicle impact shock absorber installed in front of the guard rail.

여기에서 가드레일은 도로의 양쪽 외측 또는 도로의 중앙선에 설치되어 도로의 차량 주행폭을 구획하면서 차량이 도로의 외측으로 벗어날 경우 노변의 위험으로부터 승객 및 차량을 보호하고 그 방향을 완만하게 유도시켜 뒤따르는 후속사고 를 방지하는 동시에 차량 탑승자 및 차량 파손을 방지하기 위해 사용되고, 도로용 차량충돌 충격방지장치는 가드레일 또는 콘크리트구조물 전방에 설치되어 전방으로 진행하는 차량이 충돌할 시 충격을 흡수하도록 한 것이다.The guardrails are installed on both sides of the road or on the centerline of the road to divide the roadway's vehicle width, protecting passengers and vehicles from roadside hazards and gently guiding their direction when the vehicle leaves the road. It is used to prevent the following accidents and to prevent vehicle occupants and vehicle damage, and the road vehicle collision shock prevention device is installed in front of the guardrail or concrete structure to absorb the impact when the vehicle traveling forward collides. .

이러한 종래의 가드레일은 가드레일의 구조를 보강하여 자동차가 부딪쳤을 때 도로 밖으로 이탈하여 큰 사고를 유발하는 것을 막도록 하였으나, 자동차가 부딪칠때 발생하는 충격력을 극복할 수 있는 보강구조를 만들기가 쉽지 않고, 가드레일에 자동차가 부딪쳤을때 가드레일의 강도가 강하면 자동차에 탄 사람들이 충격을 받아 생명이 위험하거나 차체가 크게 파손되는 문제가 발생한다.The conventional guard rails reinforce the structure of the guard rails to prevent them from escaping out of the road and cause a big accident when the cars hit, but it is not easy to make a reinforcement structure that can overcome the impact force generated when the cars hit. If a car is hit by a guard rail, the strength of the guard rail is strong and the people in the car are shocked, resulting in a risk of life or serious damage to the body.

그리고 차량의 인명사고는 차량이 가드레일에 충돌할 경우 보다, 후방에서 사고차량에 접근하는 차량과의 2차적인 충돌이 더 큰 사고를 불러 일으키는 문제점이 있었다.In addition, a vehicle accident has a problem that a secondary collision with a vehicle approaching the accident vehicle from the rear causes a larger accident than when the vehicle collides with the guard rail.

The purpose is to prevent secondary impulse accidents with the vehicle.
