차량 방호책Vehicle protection
본 발명은 차량 방호책에 관한 것으로서, 보다 상세하게는 레일의 강도를 보강하고, 차량 충돌시 상부레일과 하부레일이 크게 벌어지지 않고 견고하게 유지되며, 반사시트의 시인성이 우수하고, 차량 충돌 등 외력이 가해지면 지주가 기울어졌다가 탄성력에 의해 원상복원되는 차량 방호책에 관한 것이다. The present invention relates to a vehicle protection measure, and more particularly, to reinforce the strength of the rail, and to maintain the upper rail and the lower rail firmly without large gap during vehicle collision, excellent visibility of the reflective sheet, external force such as vehicle collision When this is applied, it is related to the vehicle protection measures in which the prop is tilted and restored to its original state by the elastic force.
일반적으로 차량 방호책은 도로의 중앙선 즉, 차량 주행폭을 한정하는 중앙의 황색실선을 따라 설치되어 마주보며 주행하는 차량의 진로를 엄격히 구분함과 더불어 주행차량의 반대쪽 차선 침범을 억제시킴으로 인해 차량간의 대형 충돌사고를 미연에 방지하거나, 또는 도로변이나 교량의 가장자리 부분에 설치되어 주행차량의 이탈을 방지하는 역할을 한다.In general, vehicle protection measures are installed along the center line of the road, ie, along the yellow solid line in the center limiting the driving width of the road, to strictly classify the paths of the vehicles facing each other and to suppress the invasion of the lanes opposite to the vehicle. It prevents accidents in advance or is installed at the edge of a roadside or bridge to prevent the departure of the driving vehicle.
통상적으로 차량 방호책은 도로의 중앙 또는 도로 변을 따라 일정 간격으로 수직하게 설치된 복수개의 지주와, 상기 지주들 사이를 수평하게 연결하는 레일을 포함한다.Typically, vehicle protection measures include a plurality of struts installed vertically at regular intervals along a center or side of a road, and rails for horizontally connecting the struts.
도로 중앙에 설치되는 방호책은 지주의 양측에 레일이 일정 간격 이격된 상태로 나란하게 결합되면서 쌍을 이루며, 도로 변에 설치되는 방호책은 지주의 일측면에만 레일이 설치되는 경우가 많다.The protective measures installed in the center of the road are paired side by side with the rails spaced apart at regular intervals on both sides of the shore, and the protective measures installed on the side of the road are often installed only on one side of the shore.
또한, 차체가 낮은 승용차에서부터 차체가 높은 화물차까지 모든 차량을 보호할 수 있도록 하기 위하여 레일은 지주의 상부와 하부 각각에 일정 거리 이격되게 설치된다.In addition, in order to protect all the vehicles from the passenger car with a low vehicle body to the high vehicle with a high vehicle body, rails are installed at a predetermined distance from each of the upper and lower portions of the support.
그런데, 종래의 방호책은 레일이 지주에만 결합되어 있기 때문에 차량이 지주와 지주 사이에 충돌했을 때 상부레일과 하부레일이 상측과 하측으로 벌어지면서 차량의 방호의 기능을 제대로 수행하지 못하는 경우가 종종 있었다. 특히, 도로 변의 방호책의 경우 대부분 레일이 지주의 일측에만 구비되기 때문에 차량이 도로 변의 방호책에 충돌했을 때 상부레일과 하부레일이 벌어지게 되면, 하부레일은 차량의 바퀴부분이 타고 이탈할 수 있는 발판역할을 하게 되어 대형 사고로 이어질 가능성이 크다.However, in the conventional protection measures, since the rail is coupled only to the support, when the vehicle collides between the support and the support, the upper rail and the lower rail often open to the upper side and the lower side, and thus often do not perform the function of protecting the vehicle properly. . In particular, since most rails are provided only on one side of the shore, the upper rail and the lower rail are opened when the vehicle collides with the protective fence of the roadside. The role is likely to lead to a large accident.
이러한 문제점을 해결하기 위하여 종래에도 레일의 강도를 보강하기 위한 많은 연구가 있었다. 일예로 레일 사이에 보강플레이트를 구비함으로써 레일의 강도를 보강하는 기술이 개시되었다. 그러나 이러한 노력에도 불구하고, 차량 충돌에 의한 이탈을 방지하지 못하는 문제는 여전했다. 오히려, 보강플레이트가 태풍 등의 바람의 저항으로 방호책 전체가 파손되는 문제도 발생하고 있다. In order to solve this problem, there have been many studies to reinforce the strength of the rail. As an example, a technique of reinforcing the strength of a rail by providing a reinforcing plate between rails has been disclosed. Despite these efforts, however, the problem of not being able to prevent departures due to vehicle collisions remains. Rather, the reinforcing plate is also a problem that the entire protection measures are damaged by the resistance of the wind, such as typhoons.

In addition, referring to Figure 3 (b), the rail reinforcing plate 40B may be installed so that the front portion 41 is inclined rather than perpendicular to the upper rail or the lower rail. Since the front portion 41 itself of the rail reinforcing plate (40B) is inclined in this way, the visibility is improved even if the reflective sheet (S) is attached only by processing separately without protruding obliquely.
도 4를 참조하면, 본 발명에 의한 충격흡수부재(30A,30B,30C)는 원형 또는 다각기둥형태로 형성되며, 따라서 평면형상이 폐곡선을 이루게 된다. 다만, 원기둥 형태의 지주에 밀착되어 체결될 수 있도록 일측면에는 라운드진 홈(31)이 형성되어 있다. 또한 효과적인 완충을 위해 내부가 중공된 것이 바람직하다. Referring to Figure 4, the shock absorbing members 30A, 30B, 30C according to the present invention is formed in a circular or polygonal column shape, and thus the planar shape forms a closed curve. However, rounded grooves 31 are formed at one side so as to be in close contact with the columnar support. It is also preferred that the interior is hollow for effective cushioning.

Referring to FIG. 5, as another embodiment 1 according to the present invention, a foundation 2 is formed of concrete or the like on the ground, and an L-shaped anchor 3 is used on the foundation 2. The base 4 is fixed, and includes an articulated support which sequentially stacks the lower support 20 and the support 10 on the base 4.
도 6을 참조하면, 상기 지주(10)에는 양측면에 각각 한 쌍의 충격흡수부재(30)가 체결되고, 또한 충격흡수부재(30)에는 각각 상부레일(R1) 또는 하부레일(R2)이 횡방향으로 고정된다. 또한 상부레일(R1)과 하부레일(R2) 사이에는 레일보강판(40)이 구비된다. 이러한 기술구성은 도 1에 도시된 실시예와 동일하다. Referring to FIG. 6, a pair of shock absorbing members 30 are fastened to both sides of the support 10, and an upper rail R1 or a lower rail R2 is transversely attached to the shock absorbing member 30, respectively. Direction is fixed. In addition, the rail reinforcing plate 40 is provided between the upper rail (R1) and the lower rail (R2). This technical configuration is the same as the embodiment shown in FIG.
다만, 본 실시예에서는 상기 지주(10)가 지면에 고정설치되는 것이 아니라 하부지주(20)의 상부에 적층되는 구조이다. 또한 상기 하부지주(20) 또한 베이스(4)에 고정되는 것이 아니라 유동가능하게 단지 올려지는 구조이다. 여기서 상기 하부지주(20)의 상면에는 중공된 지주(10)의 하측 내부에 삽입되는 볼록부(21)가 형성된다. However, in this embodiment, the pillar 10 is not fixed to the ground, but is stacked on top of the lower column 20. In addition, the lower column 20 is also fixed to the base 4, it is a structure that is only raised to flow. Here, the upper surface of the lower support 20 is formed with a convex portion 21 is inserted into the lower side of the hollow strut 10.
또한 상기 지주(10)의 내부에는 위부터 스프링작동판(23)과, 스프링(22)과, 스프링홀더(24)가 순차적으로 내장되고, 상기 스프링(22)을 관통하여 와이어(25)가 구비되는데, 상기 와이어(25)의 상단은 스프링 작동판(23)에 고정되고, 하단은 상기 베이스(4)에 고정된다. 여기서, 와이어(25)의 상단과 하단이 각각 스프링작동판(23)과 베이스(4)에 고정되지 않더라도 가능하지만 최소한 통과하지 못하도록 구성된다. 또한 상기 지주(10)의 상단에는 지주캡(C)이 씌워질 수 있다. In addition, a spring operating plate 23, a spring 22, and a spring holder 24 are sequentially embedded in the support 10 from above, and a wire 25 is provided through the spring 22. The upper end of the wire 25 is fixed to the spring operation plate 23, the lower end is fixed to the base (4). Here, even if the top and bottom of the wire 25 is not fixed to the spring operating plate 23 and the base 4, respectively, but configured to not pass at least. In addition, the top of the support 10 may be covered with a support cap (C).
도 7을 참조하여, 위와 같이 구성된 관절형 지주의 작동을 설명한다. 도시된 바와 같이, 차량의 충돌 등 외력이 가해지면, 레일(R1,R2)과 함께 지주(10)가 힘이 작용하는 방향으로 기울어지게 된다. 이 때, 하부지주(20)는 반작용으로 반대방향으로 기울어지기도 한다. 이와 같이 지주(10)가 기울어지게 되면, 와이어(25)가 굴절되면서 와이어(25)가 고정된 스프링작동판(23)은 지주(10) 내부에서 하강하게 된다. 이러한 동작으로 스프링(22)은 압축 탄성변형하게 되는 것이다. 물론, 상기 지주(10)는 상기 하부지주(20)의 볼록부(21)를 타고 기울어지게 된다. Referring to Figure 7, the operation of the articulated struts configured as described above will be described. As shown, when an external force such as a collision of the vehicle is applied, the support 10 is inclined in the direction in which the force acts together with the rails R1 and R2. At this time, the lower support 20 may be inclined in the opposite direction in reaction. When the strut 10 is inclined as described above, the spring 25 is fixed to the strut 10 while the wire 25 is refracted. In this operation, the spring 22 is compressive elastically deformed. Of course, the support 10 is inclined to ride the convex portion 21 of the lower column 20.
위와 같이 스프링이 압축 탄성변형되기 때문에, 스프링(22)이 인장되는 방향으로 탄성력이 발생된다. 그에 따라 스프링 작동판(23)이 다시 상승되면서 와이어(25)가 수직으로 복귀되면서 기울어졌던 지주(10)가 다시 수직으로 기립된다. 이 때, 상기 지주(10)의 하부는 다시 하부지주(20)의 상부에 형성된 볼록부(21)를 따라 안내되기 때문에 단순한 기립이 아닌 원위치로의 복귀가 가능한 것이다. Since the spring is compressive elastic deformation as described above, the elastic force is generated in the direction in which the spring 22 is tensioned. As a result, the spring 10 is raised again, and as the wire 25 returns vertically, the inclined post 10 stands up again vertically. At this time, since the lower portion of the support 10 is guided along the convex portion 21 formed on the upper portion of the lower support 20, it is possible to return to the original position instead of merely standing.
