본 발명은 차량 충돌시의 충격을 1,2차에 걸쳐 흡수하여 최대한 상쇄할 수 있는 도로용 충격흡수대에 관한 것으로, 보다 상세하게는 충돌되는 차량의 충격에 대해 전방의 공간체가 1차 찌그러져 충격을 흡수되는 동시에 후방의 스프링 판상체에 의해 2차적으로 탄성 반발되면서 차량의 충격이 구조적으로 최소화될 수 있도록 한 이중 흡수구조의 도로용 충격흡수대에 관한 것이다.The present invention relates to a road shock absorber that can absorb the impact of a vehicle crash in one or two cars to offset the impact as much as possible. More specifically, the front space is first distorted against the impact of a crashed vehicle. The present invention relates to a shock absorber for a road having a dual absorbent structure which is absorbed and elastically rebounded secondly by a rear spring plate body to minimize structural impact of the vehicle.

일반적으로 도로 중앙의 중앙분리대 또는 도로 양측의 난간에는 차량이 충돌되면서 이탈되는 것을 막으면서 차량 충돌시의 충격을 흡수시켜 차량을 보호하기 위한 충격흡수장치로서 가드레일이라 불리우는 방호벽의 충격흡수대가 설치되고 있다. 이러한 충격흡수대는 통상 도로의 중앙분리대(중앙 난간)의 경우에 양측으로 모두 설치되며, 도로 양측의 난간인 경우에는 각각 도로쪽의 일측에만 설치되는 것이 보통이다.In general, a shock absorber called a guard rail is installed as a shock absorber for protecting a vehicle by absorbing the impact of a vehicle crash while preventing the vehicle from being separated while colliding with the central divider in the middle of the road or the railings on both sides of the road. have. Such a shock absorber is usually installed on both sides in the case of a central separator (center railing) of the road, and in the case of railings on both sides of the road, it is usually installed only on one side of the road.

한편, 지금까지 소개된 대부분의 충격흡수대는 차량의 충돌에 대해 지주에 설치된 가드레일이 일정부분 찌그러지면서 차량의 충격을 흡수하게 되는데, 경우에 따라 차량의 충돌이 강할 때에는 충격흡수대가 충돌시의 충격을 이겨내지 못하고 파손되면서 심각한 교통참사로 이어지기도 한다.On the other hand, most of the shock absorbers introduced so far to absorb the impact of the vehicle as the guard rail installed on the shore against the collision of the vehicle to some extent, in some cases, when the impact of the vehicle is strong, the shock absorber is shock It is not able to cope with the damage and can lead to serious traffic disaster.

이와 같이 도로용 충격흡수대로서 중앙분리대 또는 난간의 지주에 설치되는 가디레일은, 차량 충격시의 충격하중을 제대로 흡수하여 운전자의 안전을 도모하는 동시에 도로 밖으로 차량이 이탈되는 것을 방지함에 근본적인 기능이 있다 할 수 있다.As such, the guardrail installed on the central divider or the railing pillar as a road shock absorber has a fundamental function to prevent the vehicle from falling off the road while absorbing the impact load during the vehicle shock and improving the driver's safety. can do.

도 1은 도로용 충격흡수대로서 중앙 난간의 일측에 설치된 종래의 가드레일중 일예를 도시한 것으로, 통상 차량의 접촉높이에 해당되는 중앙 난간(300)의 상부에 가드레일(100)이 고정볼트(500)로서 결합 고정되었으며, 상기 중앙 난간(300)은 도로 지면에 통상 앵커볼트로서 고정 지지되는 결합구조를 이루고 있다.1 illustrates an example of a conventional guard rail installed on one side of a central rail as a shock absorber for a road, and the guard rail 100 is fixed to the upper part of the central railing 300 corresponding to the contact height of a vehicle. 500 is fixedly coupled, and the central railing 300 forms a coupling structure fixedly supported as anchor bolts on the ground of the road.

특히 종래의 충격흡수대로서 적용시킨 가드레일(100)을 보면, 외부로부터의 충격을 받았을 때 1차적으로 탄성 반발력을 발휘하여 충돌되는 차량의 방향이 상기 가드레일(100) 반대방향으로 튕겨질 수 있도록 하는 동시에, 차량의 충격에 대해 자연스럽게 찌그러지면서 동시에 탄발 복원력을 발휘하여 차량이 심하게 파손되는 것을 최대한 상쇄시켜 줄일 수 있도록 하고 있다.In particular, when the guard rail 100 applied as a conventional shock absorber, when the impact from the outside exerts an elastic repulsion force so that the direction of the colliding vehicle can be bounced in the opposite direction to the guard rail 100 At the same time, it naturally distorts the impact of the vehicle and at the same time exerts a resilient resilience to offset the severe damage of the vehicle as much as possible.

또한 종래의 충격흡수대는 구조상 차량의 충격을 흡수하면서 동시에 차량의 파손을 효과적으로 줄일 수 있도록 최대한 얇은 두께의 곡면 판체로 형성되고 있는데, 이는 결과적으로 차량의 충돌이 강할 경우에는 활처럼 휜 곡면 판체의 설치구조로서는 정상적인 충격흡수가 이루어지지 못할 뿐만 아니라 쉽게 파손됨으로서 보다 심각한 대형사고로 이어질 수 있다는 구조적인 한계가 있다.In addition, the conventional shock absorber is formed of a curved plate with a thickness as thin as possible to absorb the impact of the vehicle at the same time, effectively reducing the damage of the vehicle, as a result of the installation of a curved curved plate when the impact of the vehicle is strong As a structure, there is a structural limitation that not only normal shock absorption is achieved but also can be easily broken, leading to more serious accidents.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 충돌되는 차량의 충격에 대해 전방의 공간체가 1차 찌그러져 충격을 흡수되는 동시에 후방의 스 프링 판상체에 의해 2차적으로 탄성 반발되면서 차량의 충격이 구조적으로 최소화될 수 있도록 하는 이중 흡수구조의 도로용 충격흡수대를 제공함에 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, the impact of the vehicle while the front space body is first crushed to absorb the impact against the impact of the impacted vehicle, while at the same time elastically rebounded second by the spring plate body of the rear It is an object of the present invention to provide a shock absorber for a road having a double absorbing structure that can be minimized structurally.

이러한 목적을 달성하기 위한 본 발명의 이중 흡수구조의 도로용 충격흡수대는, 차량 등의 충격이 발생되어 처음 전달되는 가드레일의 형상을 알파벳 "D"자 형태로 형성시키고, 내부에 충격에 의한 가드레일의 파손을 방지하기 위해 골격부를 형성하여 충격을 흡수하고 상기 가드레일과 지주 사이에 판스프링을 설치함으로서, 가드레일을 통과한 외력은 판스프링이 상하로 벌어지면서 충격을 흡수하도록 형성된 구성관계를 기술적 특징으로 한다.In order to achieve the above object, the shock absorber for a road of the dual absorption structure of the present invention forms the shape of the guard rail firstly transmitted when an impact such as a vehicle is generated in the form of an alphabet "D", and the guard by the impact inside. By forming a skeleton to prevent the damage of the rail to absorb the shock and by installing a leaf spring between the guard rail and the support, the external force passing through the guard rail has a configuration relationship formed so as to absorb the impact as the leaf spring spreads up and down It is technical feature.

이하, 본 발명의 구체적인 구성관계 및 작용을 첨부된 바람직한 실시예의 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the drawings of the preferred embodiments of the present invention will be described in detail the specific configuration and operation of the present invention.

도면에서 보는 바와 같이, 본 발명은 도로의 지면이나 교량 등의 가장자리 또는 중앙선 부분에 일정한 간격으로 지주(3)를 매입 설치시키고, 상기 지주(3)에 관통되어 형성된 볼트공(52)과 가드레일(1)에 형성된 볼트공(52)에 볼트(5)와 고정너트(51)로 체결됨으로서 기본적인 가드레일(1)을 구성한다.As shown in the drawings, the present invention is installed by installing the struts 3 at regular intervals on the edge or the center line portion of the ground, bridges, etc. of the road, the bolt hole 52 and the guard rail formed through the struts 3 A basic guard rail 1 is constituted by being fastened by the bolt 5 and the fixing nut 51 to the bolt hole 52 formed in (1).

상기 가드레일(1)을 내부에 공간부(121)가 있는 봉형태로 형성시켜 충격이 가해지면 가드레일(1)이 압박되면서 충격을 흡수하도록 하고, 상기 가드레일(1)과 지주(3)사이에 2차 충격을 흡수시키는 볼트공(52)이 형성된 판스프링(2)을 설치하여 한 구성관계를 이루게 된다.The guard rail 1 is formed in a rod shape having a space 121 therein, so that when the impact is applied, the guard rail 1 is pressed to absorb the shock, and the guard rail 1 and the support 3 are A plate spring 2 having a bolt hole 52 for absorbing secondary impact therebetween is provided to form a configuration relationship.

그리고 가드레일(1)의 후면부(12)는 판스프링(2)과 밀접하게 결합되어야 충격에 의해 서로 분리되지 않고 완충역할을 충분히 발휘할 수 있다.In addition, the rear part 12 of the guard rail 1 should be closely coupled with the leaf spring 2 so that it can sufficiently exert a buffering role without being separated from each other by the impact.

따라서 판스프링(2)과 결합되는 가드레일(1)의 후면부(12)는 판스프링(2)의 곡면부(21)와 대응되도록 형성시킨 것으로, 특히 가드레일(1)의 단면을 마치 "D"자로 형성시켜, 판스프링(2)과 밀접하게 결합시킴이 바람직하다.Therefore, the rear portion 12 of the guard rail 1 coupled to the leaf spring 2 is formed to correspond to the curved portion 21 of the leaf spring 2, and in particular, the cross section of the guard rail 1 is almost like "D "It is desirable to form a ruler and to closely couple with the leaf spring (2).

상기 판스프링(2)의 바닥면(22)과 맞닿는 지주(3)의 벽면에는 설치홈(31)을 형성하여, 충격이 전달되어 변형이 시작되는 판스프링(2)이 고정볼트(5)를 중심으로 회전되지 않고, 상하로만 벌어지면서 충격을 흡수하게 되는 것이다.The mounting groove 31 is formed on the wall surface of the support 3 which is in contact with the bottom surface 22 of the leaf spring 2, so that the shock spring is transmitted and the deformation of the leaf spring 2 starts with the fixing bolt 5. It is not rotated around the center, but only up and down to absorb shock.

또한 가드레일(1)의 내측에 형성된 공간부(121)에는 상기 가드레일(1)의 두께가 얇아 낮아지는 강성을 높임으로써, 외력에 의해 가드레일(1)이 파손되는 것을 방지하는 골격부(122)를 형성하는 것이 바람직하다.In addition, the space portion 121 formed inside the guard rail 1 has a skeleton portion which prevents the guard rail 1 from being damaged by external force by increasing the rigidity of the thickness of the guard rail 1 being lowered. 122).

그리고 상기 가드레일의 전면부(11)에는 가드레일(1)과 판스프링(2)과 지주(3)를 체결하는 고정볼트(5)가 외부로 노출되는 것을 방지하도록 요홈부(111)를 형성시키고, 나아가 상기 요홈부(111)에 빛에 상응하는 형광부재(4)를 설치하여 운 전자가 쉽게 위험구간을 파악하도록 구성된다.In addition, the front portion 11 of the guard rail is formed with a recess 111 to prevent the fixing bolt 5 for fastening the guard rail 1, the leaf spring 2, and the support 3 to the outside. Further, by installing a fluorescent member 4 corresponding to the light in the groove 111, the driver is configured to easily identify the danger zone.

첨부된 도면 도 5는 지주가 설치된 위치에서 차량이 충돌되었을 때 충격을 흡수하는 도면으로, 차량 등에 의해 충격이 발생되면 먼저 가드레일에 충격이 전달된다. 그러면 압박된 가드레일은 충격을 흡수하면서 눌려지게 된다. 이때, 가드레일의 내부에 형성된 골격부가 외력에 의해 가드레일이 파손되는 것을 방지한다.5 is a view of absorbing shock when a vehicle collides at a location where a support is installed. When an impact is generated by a vehicle or the like, an impact is first transmitted to the guard rail. The pressed guardrail is then pressed while absorbing the impact. At this time, the skeleton portion formed inside the guardrail prevents the guardrail from being damaged by an external force.

가드레일에서 전달되는 충격은 판스프링에 전달되고, 스프링은 지주에 형성된 요홈부를 따라 상하로 벌어지면서 충격을 흡수하게 되며, 체결된 볼트는 충돌에 의해 발생되는 외력 만큼 뒤로 후퇴되어, 사고 후 돌출된 볼트에 의해 발생되는 사고를 방지하게 되는 것이다. 본 발명은 전술한 실시 예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있음은 물론이다.The shock transmitted from the guard rail is transmitted to the leaf spring, and the spring absorbs the shock as it rises up and down along the recess formed in the support, and the fastened bolt is retracted backward by the external force generated by the collision and protrudes after the accident. This will prevent accidents caused by bolts. The present invention is not limited to the above-described embodiments, and of course, various modifications can be made within the scope of the technical idea of the present invention.

이상에서와 같이 본 발명의 이중 흡수구조의 도로용 충격흡수대에 의하면, 충돌되는 차량의 충격에 대해 전방의 공간체가 1차 찌그러져 충격을 흡수되는 동시에 후방의 스프링 판상체에 의해 2차적으로 탄성 반발되면서 차량의 충격이 구조적으로 최소화될 수 있도록 한다.As described above, according to the road shock absorber of the dual absorption structure of the present invention, while the front space body is first crushed by the impact of the impacted vehicle, the shock is absorbed and the second elastic repulsion is performed by the rear spring plate body. The impact of the vehicle can be minimized structurally.

즉, 구성되는 가드레일이 내부에 공간부가 형성된 봉형태의 "D"자 형태로 형성하여 1차로 발생되는 충격을 흡수하면서도, 내부에 형성된 골격부가 가드레일의 파손을 방지하여 차량이 낭떠러지 등으로 떨어져 발생되는 2차 사고를 미연에 방지할 수 있다. 또한 지주와 가드레일 사이에는 충격을 흡수하는 판스프링에 의해 차 량이 지주가 설치된 위치에서 충돌이 되더라도 이를 2중으로 충격을 흡수하여 차량과 탑승자를 2차 사고로부터 보다 확실하게 보호할 수 있는 작용효과를 제공될 것으로 기대된다.That is, the guardrail is formed in the form of a rod-shaped "D" formed with a space therein to absorb the primary shock, while the skeleton formed therein prevents the guardrail from being damaged and the vehicle falls off the cliff. Secondary accidents can be prevented. In addition, even if the vehicle collides in the position where the support is installed by the shock absorbing leaf spring between the support and the guard rail, it absorbs the double shock to provide a more effective effect of protecting the vehicle and the occupant from the second accident. It is expected to be provided.
