충격 흡수형 단부시설물Shock Absorbing End Facility
본 발명은 충격 흡수형 단부시설물에 관한 것으로서, 보다 상세하게는, 충돌 사고 발생 시에 단부시설물의 부피가 감소하도록 압축되면서 충격을 흡수할 수 있고, 단부시설물이 압축되는 속도를 연기시키면서 보다 효과적으로 충격을 흡수할 수 있도록 하는 충격 흡수형 단부시설물에 관한 것이다.The present invention relates to an impact-absorbing end facility, and more particularly, to absorb shock while compressing to reduce the volume of the end facility in the event of a crash, and more effectively while delaying the speed at which the end facility is compressed. It relates to a shock absorbing end facility that can absorb the.
종래의 일반적인 중앙분리대 및 가드레일은, 지면에 수직하게 설치한 기둥의 양측에 완충기를 개재시킨 상태로 파형으로 굴곡된 패널부재를 차선의 방향과 평행하게 설치하고, 중앙분리대 및 가드레일의 단부에는 양측 패널부재의 날카로운 단부를 커버하는 단부마감대가 설치된다.Conventional center separators and guardrails are provided with curved panel members parallel to the lane direction with buffers interposed on both sides of pillars perpendicular to the ground, and at the ends of the center separators and guardrails. An end finisher covering the sharp ends of both panel members is provided.
단부마감대는 평판형의 철판을 "U"자형으로 구부리며, 패널본체의 단부와 결합 설치되는 양단부의 상하부를 패널본체의 경사진 단부와 밀착되게 경사부를 형성하여 그 경사부를 형성한 단부마감대의 양단부를 패널본체의 단부에 볼트로 결합 설치하였다.The end finisher bends a flat iron plate in a "U" shape, and forms both inclined portions to be in close contact with the inclined end portion of the panel body by forming an inclined portion in close contact with the inclined end portion of the panel body. The bolt was attached to the end of the panel body.
이와 같은 중앙분리대 및 가드레일은 차선방향과 평행하게 설치되어서 차도를 주행하던 차량이 중앙분리대 또는 가드레일에 부딪칠 때 대부분이 패널본체의 외측면에 경사방향으로 부딪치게 되고, 중앙분리대 또는 가드레일의 단부에 부딪칠 때는 단부마감대의 중앙부에 부딪치게 된다.Such a median separator and guard rails are installed parallel to the lane direction so that when the vehicle driving on the roadway hits the median separator or guard rail, most of them are inclined against the outer surface of the panel body, and the median or guard rail When hitting the end, it hits the center of the end finisher.
상기와 같이 단부마감대의 중앙부에 차량이 부딪치게 될 때 패널본체의 날카로운 단부를 둥글게 구부려진 단부마감대로 커버해줌에 따라 차량에 치명적인 손상을 커버할 수 있었다.As described above, when the vehicle collides with the center portion of the end closure, the vehicle may cover the damage to the vehicle by covering the sharp end of the panel body with the rounded end closure.
그러나 단부마감대의 중앙부에 매우 강력한 충격하중이 작용할 때는 평판형태의 철판을 "U"자형으로 구부린 것에 따라 단부마감대는 강력한 충격하중을 완충시키거나 그 충격하중에 지지하는 지지력이 턱없이 부족하여 단부마감대가 휴지조각처럼 구부려짐은 물론이고, 차량과 탑승자가 크게 다치게 되는 문제를 야기하게 되는 문제가 있었다.However, when a very strong impact load acts on the center of the end cap, the flat plate-shaped steel plate is bent into a “U” shape, so that the end cap has a strong lack of support to buffer the strong impact load or to support the impact load. Not only was the bench bent like a piece of toilet paper, but there were also problems that could cause serious injuries to the vehicle and occupants.
상기한 바와 같은 문제점을 해결하기 위하여 종래 기술에 따른 도로용 단부 시설물은, 지면에 수직 설치되는 기둥의 양측에 가드레일이 완충기를 개재시킨 상태로 설치되는 도로시설물의 단부에 "U"자형으로 구부려진 단부마감대를 설치하고, 단부마감대는 산형돌출부의 사이에 평탄부가 일체로 연결 형성된 파형으로 형성되고, 단부마감대의 반원형으로 구부려진 라운딩부의 중앙부 후면과 기둥의 정면 사이에 연질 합성수지재로서 바 형태로 형성한 완충기가 상하길이방향으로 설치된다.In order to solve the problems as described above, the road end facility according to the prior art is bent in the shape of the "U" at the end of the road facility installed with the guard rail interposed between the sides of the pillar vertically installed on the ground. The end finisher is provided, and the end finisher is formed in a wave form in which flat portions are integrally connected between the protrusions, and is formed as a soft synthetic resin material between the back of the center of the rounded portion bent in a semicircle of the end finisher and the front of the column. The shock absorber formed in the vertical direction is installed.
또한, 종래 기술에 따른 도로용 단부 시설물은, 도로의 양단부에 설치되는 가드레일에 적용될 수 있으며, 이는 공개특허공보 제10-2015-0031868호 파단 기능의 지주를 갖는 가드레일의 충격흡수장치에 기재된 바와 같이 단부 시설물이 설치되는 가드레일은 차량의 정면 충돌 및 측면 충돌 시에 완충작용을 행하도록 설치될 수 있다.In addition, the road end facility according to the prior art, can be applied to the guard rail is installed on both ends of the road, which is described in the shock absorbing device of the guard rail having a prop of the breaking function of Publication No. 10-2015-0031868 As described above, the guardrail on which the end facility is installed may be installed to cushion the frontal and side impacts of the vehicle.

도 1은 본 발명의 제1실시예에 따른 충격 흡수형 단부시설물이 도시된 사시도이고, 도 2는 본 발명의 제1실시예에 따른 충격 흡수형 단부시설물이 도시된 작동상태도이고, 도 3은, 도 1 및 도 2에 도시된 충격 흡수형 단부시설물의 가변부 및 브래킷 연결구조의 상세 확대도이다.1 is a perspective view of the shock absorbing end facility according to the first embodiment of the present invention, Figure 2 is an operating state diagram showing the shock absorbing end facility according to the first embodiment of the present invention, Figure 3 1 and 2 is a detailed enlarged view of the variable portion and the bracket connection structure of the shock absorbing end facility shown in FIG.
도 1 내지 도 3을 참조하면, 본 발명의 일 실시예에 따른 충격 흡수형 단부시설물은, 도로의 가드레일 또는 중앙분리대의 단부에 연속되게 배치되는 복수 개의 패널부(50)와, 가드레일 또는 중앙분리대의 단부에 연속되게 지지되도록 복수 개의 패널부(50)를 연결하는 연결부(110)와, 연결부(110)가 패널부(50)를 따라 이동 가능하게 결합되도록 패널부(50)에 구비되는 완충이동부(100)를 포함한다.1 to 3, the shock absorbing end facility according to an embodiment of the present invention, a plurality of panel portion 50, guard rail or continuously disposed at the end of the guardrail or the median of the road The connection part 110 for connecting the plurality of panel parts 50 so as to be continuously supported at the end of the center separator, and the panel part 50 is provided so that the connection part 110 is movably coupled along the panel part 50. It includes a buffer moving unit (100).
따라서 차량 충돌 시에 패널부(50)의 단부에 충격이 전달되면 다수 개의 패널부(50)가 일측 방향으로 이동되면서 단부시설물의 부피가 압축되면서 충격을 흡수하게 된다.Therefore, when an impact is transmitted to an end portion of the panel portion 50 during a vehicle collision, the plurality of panel portions 50 are moved in one direction while the volume of the end facility is compressed to absorb the impact.
이때, 측 방향으로 이동되는 패널부(50)는, 다수 개의 패널부(50)를 연결하는 연결부(110)가 완충이동부(100)를 따라 이동되면서 패널부(50)가 측 방향으로 이동되도록 안내하게 된다.At this time, the panel unit 50 which is moved in the lateral direction is such that the panel unit 50 is moved in the lateral direction while the connection unit 110 connecting the plurality of panel units 50 is moved along the buffer moving unit 100. You will be guided.
연결부(110)는, 패널부(50)에 구비되는 체결홀부(102a)와, 복수 개의 패널부(50)가 연결되도록 복수 개의 체결홀부(102a)에 동시에 삽입되는 체결부재(116)와, 체결부재(116)와 결합되는 너트부재(116a)를 포함한다.The connecting portion 110 includes a fastening hole portion 102a provided in the panel portion 50, a fastening member 116 inserted into the plurality of fastening hole portions 102a so as to be connected to the plurality of panel portions 50, and fastening. And a nut member 116a coupled with the member 116.
패널부(50)의 단부에는 체결홀부(102a)가 형성되므로 한 상의 패널부(50)를 겹쳐지도록 배치시켜 한 쌍의 체결홀부(102a)가 포개지게 하고, 한 쌍의 체결홀부(102a)에 체결부재(116)를 삽입한 후에 체결부재(116)와 너트부재(116a)를 체결하여 한 쌍의 패널부재를 연속되게 연결하게 된다.Since the fastening hole portion 102a is formed at the end of the panel portion 50, the fastening hole portion 102a is disposed so as to overlap the upper panel portion 50 so that the pair of fastening hole portions 102a overlap, and the pair of fastening hole portions 102a are provided. After the fastening member 116 is inserted, the fastening member 116 and the nut member 116a are fastened to connect the pair of panel members continuously.
완충이동부(100)는, 체결홀부(102a)로부터 패널부(50)를 따라 연장되는 슬라이딩홀부(102)와, 슬라이딩홀부(102)가 패널부(50)의 이동방향과 이격되게 굴곡되어 이루어지는 곡선부(106)를 포함하므로 차량 충돌 시에 다수 개의 패널부(50)가 측 방향으로 이동되면서 포개질 때에 체결부재(116) 및 너트부재(116a)가 슬라이딩홀부(102)를 따라 이동되면서 패널부(50)를 측 방향으로 안내하게 된다.The buffer moving part 100 includes a sliding hole part 102 extending from the fastening hole part 102a along the panel part 50, and the sliding hole part 102 is bent to be spaced apart from the moving direction of the panel part 50. Since the curved portion 106 includes a plurality of panel parts 50 moving laterally during vehicle collision, the fastening member 116 and the nut member 116a move along the sliding hole part 102 when the panel is stacked. The part 50 is guided laterally.
이때, 체결부재(116)는 곡선부(106)를 따라 상층 및 하측으로 교호로 이동되며 체결부재(116)의 이동경로가 물결 모양을 이루게 되므로 체결부재(116)가 슬라이딩홀부(102)를 따라 이동되는 속도가 설정속도 이상으로 상승되는 것을 방지할 수 있게 된다.At this time, the fastening member 116 is alternately moved to the upper and lower sides along the curved portion 106 and the movement path of the fastening member 116 is wavy, so the fastening member 116 along the sliding hole portion 102. It is possible to prevent the moving speed from rising above the set speed.
따라서 패널부(50)가 측 방향으로 이동되는 속도가 감속되어 차량 충돌에 의한 충격을 보다 효과적으로 완충시키게 되므로 차량의 파손 정도 및 인명 피해를 줄일 수 있게 된다.Therefore, the speed at which the panel unit 50 moves in the lateral direction is decelerated to more effectively cushion the impact caused by the collision of the vehicle, thereby reducing the degree of damage and the casualty of the vehicle.
슬라이딩홀부(102)는, 체결홀부(102a)로부터 연장되고 체결홀부(102a)와 비교하여 폭이 좁게 형성되는 제1홀부(102b)와, 제1홀부(102b)로부터 연장되고 제1홀부(102b)와 비교하여 폭이 좁게 형성되는 제2홀부(102c)와, 제2홀부(102c)로부터 연장되고 제2홀부(102c)와 비교하여 폭이 좁게 형성되는 제3홀부(102d)를 포함한다.The sliding hole 102 has a first hole portion 102b extending from the fastening hole portion 102a and narrower than the fastening hole portion 102a, and extending from the first hole portion 102b and extending from the first hole portion 102b. 2) the second hole portion 102c having a narrower width than the second hole portion 102c and a third hole portion 102d extending from the second hole portion 102c and having a narrower width than the second hole portion 102c.
체결홀부(102a)는 패널부(50)의 단부에 좌우방향으로 긴 장공 모양으로 형성되고, 체결홀부(102a)의 일단부로부터 측 방향으로 상측 및 하측으로 교호로 굴곡되는 물결 모양을 이루면서 슬라이딩홀부(102)가 연장되는데, 제1홀부(102b) 내지 제3홀부(102d)까지 갈수록 폭이 단계적으로 좁아지게 형성된다.The fastening hole 102a is formed in the shape of an elongated long hole in the left and right direction at the end of the panel part 50, and forms a wavy shape that alternately bends upward and downward in the lateral direction from one end of the fastening hole 102a. 102 is extended, and the width is gradually narrowed toward the first hole portion 102b to the third hole portion 102d.
체결부재(116)가 슬라이딩홀부(102)를 따라 이동할 때에는 체결홀부(102a)로부터 일측 방향으로 이동되면서 제1홀부(102b)를 따라 이동되고, 제1홀부(102b)를 통과한 체결부재(116)는 제2홀부(102c)를 따라 이동된 후에 제3홀부(102d)를 따라 이동하게 된다.When the fastening member 116 moves along the sliding hole part 102, the fastening member 116 moves along the first hole part 102b while moving in one direction from the fastening hole part 102a and passes through the first hole part 102b. ) Moves along the second hole 102c and then moves along the third hole 102d.
이때, 제1홀부(102b) 내지 제3홀부(102d)를 차례로 지나는 체결부재(116)는 단계적으로 폭이 좁아지는 슬라이딩홀부(102)를 지나면서 슬라이딩홀부(102)와 체결부재(116) 사이의 마찰력이 상승되면서 체결부재(116)가 이동되는 속도가 감속되어 패널부(50)의 이동속도를 감속시키게 된다.At this time, the fastening member 116 which passes through the first hole part 102b to the third hole part 102d in turn passes between the sliding hole part 102 and the fastening member 116 while passing through the sliding hole part 102 which is narrowed step by step. As the frictional force is increased, the speed at which the fastening member 116 is moved is reduced to reduce the moving speed of the panel unit 50.
여기서, 제1홀부(102b)의 길이는 제2홀부(102c)의 길이와 동일하거나 유사하게 형성되고, 제3홀부(102d)의 길이는 제1홀부(102b) 및 제2홀부(102c)와 비교하여 길게 형성되므로 제1홀부(102b) 및 제2홀부(102c)를 지나면서 감속되는 체결부재(116)의 속도는 제3홀부(102d)를 지나면서 현저하게 감속되므로 패널부(50)의 이동속도가 현저하게 감속되면서 완충작동을 행하게 된다.Here, the length of the first hole 102b is the same as or similar to the length of the second hole 102c, and the length of the third hole 102d is the same as that of the first hole 102b and the second hole 102c. Since the length of the fastening member 116 that is reduced by passing through the first hole 102b and the second hole 102c is significantly reduced by passing through the third hole 102d because it is formed longer than the panel portion 50. As the movement speed is significantly reduced, the shock absorbing operation is performed.
제1홀부(102b), 제2홀부(102c) 및 제3홀부(102d)의 길이는, 3:3:4로 이루어지는 것이 바람직하며, 이는 체결부재(116)의 이동이 완료되는 마지막에 부분에 마찰력을 최대로 증가시켜 체결부재(116) 및 패널부(50)의 이동속도를 급격히 상대적으로 긴 시간 동안 감속시키면서 체결부재(116)와 패널부(50)를 정지시키기 위한 것이다.The length of the first hole portion 102b, the second hole portion 102c and the third hole portion 102d is preferably 3: 3: 4, which is at the end of the movement of the fastening member 116. It is to stop the fastening member 116 and the panel unit 50 while increasing the friction force to the maximum while rapidly decelerating the moving speed of the fastening member 116 and the panel unit 50 for a relatively long time.
또한, 본 발명의 다른 실시예에 따른 슬라이딩홀부(102)는, 체결홀부(102a)로부터 연장되고 체결홀부(102a)와 비교하여 폭이 좁게 형성되는 제1홀부(102b)와, 제1홀부(102b)로부터 연장되고 제1홀부(102b)와 비교하여 폭이 넓게 형성되는 제2홀부(102c)와, 제2홀부(102c)로부터 연장되고 제2홀부(102c)와 비교하여 폭이 넓게 형성되는 제3홀부(102d)를 포함한다.In addition, the sliding hole portion 102 according to another embodiment of the present invention, the first hole portion 102b and the first hole portion (102b) which extends from the fastening hole portion 102a and is formed narrower than the fastening hole portion 102a. A second hole portion 102c extending from 102b and wider than the first hole portion 102b, and a second hole portion 102c extending from the second hole portion 102c and wider than the second hole portion 102c. The third hole portion 102d is included.
본 발명의 다른 실시예에 따른 슬라이딩홀부(102)는, 제1홀부(102b) 내지 제3홀부(102d)로 갈수록 폭이 넓어지는 것이 특징이고, 이는 차량 충돌 시에 발생되는 충격이 충돌 초기에 가장 큰 것을 감안하여 차량 충돌 초기에 체결부재(116) 및 패널부(50)의 이동속도를 효과적으로 줄이기 위한 것이다.The sliding hole portion 102 according to another embodiment of the present invention is characterized in that the width becomes wider toward the first hole portion 102b to the third hole portion 102d, so that an impact generated at the time of a vehicle collision is at the beginning of the collision. In consideration of the largest to effectively reduce the moving speed of the fastening member 116 and the panel unit 50 at the beginning of the vehicle collision.
본 실시예는, 체결부재(116)가 제1홀부(102b)를 지나는 동안 큰 마찰력에 의해 패널부(50)의 속도가 급격히 감소한 후에는 체결부재(116)가 제2홀부(102c) 및 제3홀부(102d)를 지나면서 마찰력이 감소되면서 이동되므로 패널부(50)가 충분히 이동되면서 감소된 충격을 마지막까지 감소시킬 수 있게 된다.In this embodiment, after the fastening member 116 passes the first hole portion 102b rapidly after the speed of the panel portion 50 is rapidly decreased by the large friction force, the fastening member 116 is formed of the second hole portion 102c and the first hole portion 102c. Since the friction force is reduced while moving through the three-hole portion 102d, the panel portion 50 is sufficiently moved to reduce the reduced impact to the end.
제1홀부(102b), 제2홀부(102c) 및 제3홀부(102d)의 폭은 상기한 바와 같이 단계적으로 커지는 구조, 또는 단계적으로 작아지는 구조로 형성될 수 있고, 제1홀부(102b), 제2홀부(102c) 및 제3홀부(102d)의 폭이 작아지다가 다시 커지는 구조로 형성되거나, 폭이 커지다가 다시 작아지는 구조로도 형성될 수 있다.The width of the first hole portion 102b, the second hole portion 102c, and the third hole portion 102d may be formed in a step-wise structure or a step-down structure as described above, and the first hole portion 102b. The width of the second hole portion 102c and the third hole portion 102d may be formed to decrease in size and then increase, or may also be formed to increase in width and decrease in size.
이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 다른 실시예에 따른 슬라이딩홀부(102)의 구조적 특징에 대하여 구체적인 도면은 생략하기로 한다.This can be easily changed and implemented by those skilled in the art with the technical configuration of the present invention will be omitted for the structural features of the sliding hole 102 according to another embodiment.
본 실시예에 따른 패널부(50)는, 가이드레일의 단부에 설치되는 패널부재를 포함하고, 패널부재에 설치되는 단부시설물은, 가드레일에 연결되고 제1완충부(53)가 구비되는 패널부재(50)와, 패널부재(50)를 지지하고 지면에 직립되는 지주부(10)를 포함한다.The panel unit 50 according to the present embodiment includes a panel member installed at an end portion of the guide rail, and an end facility installed at the panel member is connected to the guard rail and provided with a first buffer unit 53. A member 50 and a support 10 supporting the panel member 50 and standing upright on the ground are included.
본 실시예는, 도로의 중앙부에 설치되는 중앙분리대 또는 도로의 가장자리에 설치되는 가드레일의 단부에 설치되어 충돌 사고 발생 시에 충격을 흡수하는 시설물이며, 충돌 사고가 발생되면 제1완충부(53) 및 제2완충부(80)의 작용에 의해 충격이 2차에 걸쳐 흡수되므로 인명 피해를 줄일 수 있게 된다.The present embodiment is a facility installed at the end of the guardrail is installed on the edge of the road or the median is installed in the center of the road to absorb the impact when a crash occurs, the first shock absorber 53 ) And the shock absorbed by the action of the second buffer unit 80 over the secondary it is possible to reduce the damage to life.
제1완충부(53)는, 패널부재(50)의 단부에 설치되고 곡면을 이루며 내부 공간을 형성하는 설치프레임(52a)과, 설치프레임(52a) 내부에 설치되는 탄성부재(52b)를 포함하므로 패널부재(50)의 단부에 차량이 충돌되는 경우에는 설치프레임(52a)이 변형되면서 탄성부재(52b)가 압축되어 1차로 충격 흡수를 행하게 된다.The first shock absorbing portion 53 includes an installation frame 52a installed at the end of the panel member 50 and forming a curved surface to form an inner space, and an elastic member 52b installed inside the installation frame 52a. Therefore, when the vehicle collides with the end of the panel member 50, the mounting frame 52a is deformed and the elastic member 52b is compressed to absorb the primary shock.
차량 충돌에 의한 충격이 완전히 흡수되지 않고 지속되는 경우에는 제2완충부(80)의 작용에 의해 다수 개의 패널부재(50)가 서로 겹쳐지도록 슬라이딩되면서 압축되어 2차에 걸친 충격 흡수가 이루어지게 된다.When the impact due to the vehicle collision is not completely absorbed and persists, the plurality of panel members 50 are compressed while sliding so as to overlap each other by the action of the second shock absorbing unit 80, thereby absorbing the secondary shock. .
따라서 본 실시예에 따른 단부시설물에 차량 충돌이 발생되는 경우에는 제1완충부(53) 및 제2완충부(80)에 의해 2차에 걸쳐 충격 흡수가 이루어지므로 인명 피해를 효과적으로 줄일 수 있게 된다.Therefore, when a vehicle collision occurs in the end facility according to the present embodiment, the first shock absorbing unit 53 and the second shock absorbing unit 80 are shock-absorbed in two steps, thereby effectively reducing casualties. .
여기서, 1차 충격 흡수와 2차 충격 흡수는 미세한 시간 차이를 두고 발생될 수 있으므로 거의 동시에 진행되는 작용으로 간주될 수 있으며, 이는 본 발명의 기술구성을 인지한 당업자가 용이하게 인지할 수 있는 것이므로 1차 충격 흡수와 2차 충격 흡수 사이의 시간 차이에 대한 구체적인 설명은 생략하기로 한다.Here, since the first shock absorption and the second shock absorption may be generated with a slight time difference, it may be regarded as an action that proceeds at about the same time, since it is easily recognized by a person skilled in the art who recognizes the technical configuration of the present invention. A detailed description of the time difference between the primary shock absorption and the secondary shock absorption will be omitted.
본 실시예의 패널부(50)는 복수 개가 유동 가능하도록 연속되게 연결되므로 가드레일 단부에 2개 이상의 패널부(50)가 서로 슬라이딩 가능하게 연결되어 단부시설물을 이루게 된다.Since the panel portion 50 of the present embodiment is continuously connected to allow a plurality of flows, two or more panel portions 50 are slidably connected to each other to form an end facility.
따라서 패널부(50)의 단부에 충돌 사고가 발생되면 다수 개의 패널부(50)가 서로 겹쳐지도록 압축되면서 충격 흡수를 행할 수 있게 된다.Therefore, when a collision accident occurs at the end of the panel unit 50, the plurality of panel units 50 may be compressed to overlap each other, and thus shock absorption may be performed.
지주부(10)는, 지면에 설치되는 제1기둥(12)과, 제1기둥(12)에 삽입되는 제2기둥(14)과, 제2기둥(14)에 유동 가능하게 연결되고 패널부(50)가 고정되는 브래킷(32)이 설치되는 지지대(30)를 포함한다.The strut portion 10 is connected to the first pillar 12 installed on the ground, the second pillar 14 inserted into the first pillar 12, and the second pillar 14 so as to be flowable. The support 30 includes a bracket 32 to which the 50 is fixed.
상기한 바와 같이 제1기둥(12)은 지면에 삽입되어 고정된 것이므로 기존의 가드레일에 설치된 제1기둥(112)을 절단하여 제1기둥(12)의 내부로 상대적으로 지름이 작은 제2기둥(14)을 삽입하면 본 발명에 따른 단부시설물을 용이하게 설치할 수 있게 되고, 기존의 제1기둥(112)을 제거하는 작업 및 새로운 제1기둥(12)을 시공하는 공정이 생략되므로 단부시설물을 교체하는데 소요되는 시간 및 비용을 절감할 수 있게 된다.As described above, since the first pillar 12 is inserted into the ground and is fixed, the first pillar 112 installed in the existing guard rail is cut and the second pillar having a relatively small diameter inside the first pillar 12. Inserting the end 14 facilitates the installation of the end facility according to the present invention, and thus eliminates the process of removing the existing first pillar 112 and the process of constructing the new first column 12. This saves time and costs for replacement.
제1기둥(12)에 삽입된 제2기둥(14)의 상단에는 지지대(30)가 유동 가능하게 연결되므로 충돌 사고가 발생되어 패널부(50)가 서로 겹쳐지도록 압축될 때에 각각의 패널부(50)를 지지하는 지지대(30)도 패널부(50)와 같이 유동되게 된다.Since the support 30 is connected to the upper end of the second pillar 14 inserted into the first pillar 12 so that a collision accident occurs and the panel portions 50 are compressed to overlap each other, each panel portion ( Support 30 for supporting 50 is also to flow with the panel portion (50).
따라서 차량 충돌 시에 지면에 고정된 종래의 지지대(30)에 의해 차량에 가해지던 충격량을 감소시킬 수 있게 된다.Therefore, it is possible to reduce the amount of impact applied to the vehicle by the conventional support 30 fixed to the ground at the time of the vehicle crash.
브래킷(32)은, 제2기둥(14)에 설치되는 본체(34)와, 본체(34)로부터 연장되고 패널부(50)가 지지되는 연장부(32b, 32c)를 포함하므로 지지대(30)의 상단을 본체(34)에 형성되는 홀부에 삽입하여 볼트결합 또는 용접작업에 의해 지지대(30)와 본체(34)를 연결한다.The bracket 32 includes a main body 34 installed on the second pillar 14 and extension portions 32b and 32c extending from the main body 34 and supporting the panel portion 50. Insert the upper end of the hole formed in the main body 34 to connect the support 30 and the main body 34 by bolting or welding operation.
연장부(32b)는 본체(34)로부터 측 방향으로 연장되어 본체(34)의 양단부에 각각 패널부재(50)가 연결될 수 있도록 연장부(32b, 32c)와 패널부(50)는 용접작업 또는 볼트결합에 의해 연결되므로 한 쌍의 패널부(50)가 브래킷(32)을 중심으로 간격을 유지하도록 연결될 수 있게 된다.The extension part 32b extends laterally from the main body 34 so that the panel members 50 can be connected to both ends of the main body 34, respectively. Since it is connected by the bolt coupling, a pair of panel portions 50 can be connected to maintain a gap around the bracket (32).
본체(34)는, 가드레일을 이루는 고정패널부(150)를 지지하는 제1본체(34a)와, 가드레일을 이루는 고정패널부(150)에 유동 가능하게 연결되는 패널부(50)를 지지하고 제1본체(34a)와 비교하여 좁게 형성되는 제2본체(34b)를 포함한다.The main body 34 supports the first main body 34a for supporting the fixed panel unit 150 that forms the guard rail and the panel unit 50 that is fluidly connected to the fixed panel unit 150 that forms the guard rail. And a second body 34b that is narrower than the first body 34a.
기존의 가드레일을 이루는 고정패널부(150)는 상대적으로 넓은 제1본체(34a)에 설치되므로 가드레일은 단부시설물과 비교하여 폭이 넓게 형성되고, 제1본체(34a)와 제2본체(34b)를 연결하는 경사패널부는 폭이 좁아지도록 측면에 굴곡부(50a)가 형성되므로 충돌 사고 발생 시에 다수 개의 패널부(50)가 가드레일 측으로 압축되면서 다수 개의 패널부(50)가 서로 겹쳐지고, 굴곡부(50a)를 따라 벌어지면서 슬라이딩되어 패널부(50)의 압축작동이 서서히 중단되도록 유도하게 된다.Since the fixed panel part 150 forming the conventional guard rail is installed in the relatively wide first body 34a, the guard rail is formed wider than the end facility, and the first body 34a and the second body ( Since the inclined panel portion connecting the 34b) is formed with a bent portion 50a on the side thereof, the plurality of panel portions 50 are overlapped with each other while the plurality of panel portions 50 are compressed to the guardrail side when a collision accident occurs. , Sliding along the curved portion 50a to induce the compression operation of the panel portion 50 to be gradually stopped.
여기서, 제1본체(34a)와 제2본체(34b)의 폭은 가드레일의 구조에 따라 다양하게 가변될 수 있으며, 이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 다른 실시예에 따른 구체적인 도면이나 설명은 생략하기로 한다.Here, the width of the first body (34a) and the second body (34b) can be varied in various ways depending on the structure of the guardrail, which can be easily changed by those skilled in the art to recognize the technical configuration of the present invention Therefore, specific drawings or descriptions according to other embodiments will be omitted.
본 실시예는, 제2기둥(14)을 제1기둥(12)에 유동 가능하게 연결하는 가변부(70)를 더 포함하므로 충돌 사고 발생 시에 패널부재(50)가 서로 겹쳐지도록 압축될 때에 가변부(70)의 작용에 의해 지지대(30)가 유동되므로 패널부재(50)의 압축작동이 원활히 이루어지도록 한다.Since the present embodiment further includes a variable portion 70 that fluidly connects the second pillar 14 to the first pillar 12, when the panel members 50 are compressed to overlap each other when a collision accident occurs, Since the support 30 flows by the action of the variable portion 70, the compression operation of the panel member 50 is smoothly performed.
가변부(70)는, 제2기둥(14)을 제1기둥(12)부에 슬라이딩시켜 조립하도록 연결하는 유동연결부(72)와, 유동연결부(72)에 의해 슬라이딩되는 제2기둥(14)의 슬라이딩 운동을 억제하는 유동억제부(74)를 포함한다.The variable portion 70 includes a flow connecting portion 72 for sliding and assembling the second pillar 14 to the first pillar 12 and a second pillar 14 sliding by the floating connecting portion 72. Flow control unit 74 for suppressing the sliding movement of the.
유동연결부(72)는 제2기둥(14)과 지지대(30)를 슬라이딩 방식으로 연결하므로 제2기둥(14)과 지지대(30)를 결합할 때에 제2기둥(14)의 상단에 지지대(30)의 하단을 슬라이딩 방식으로 삽입하여 지지대(30)를 설치할 수 있으므로 별도의 볼트작업 또는 용접작업을 생략하여 지지대(30)의 설치를 행할 수 있게 된다.Since the flow connecting portion 72 connects the second pillar 14 and the support 30 in a sliding manner, the support 30 at the upper end of the second pillar 14 when the second pillar 14 and the support 30 are coupled to each other. Since the support 30 can be installed by inserting the lower end of the support in a sliding manner, it is possible to perform the installation of the support 30 by omitting a separate bolt work or welding work.
또한, 충돌 사고 발생 시에는 지지대(30)의 하단이 제2기둥(14)의 상단으로부터 슬라이딩되면서 분리되므로 패널부(50) 및 지지대(30)가 고정되지 않은 상태를 이루게 되므로 다수 개의 패널부(50)가 겹쳐지도록 압축되면서 충격 흡수를 행하게 된다.In addition, when the collision occurs, the lower end of the support 30 is separated while sliding from the upper end of the second pillar 14, so that the panel unit 50 and the support 30 are not fixed, so that a plurality of panel units ( 50) is compressed so as to overlap the shock absorption.

슬라이딩홈부(72b)의 단부에는 상측 방향으로 경사지면 곡면으로 형성되는 곡면부(72c)가 형성되므로 슬라이딩홈부(72b)가 연결패널(72a)로부터 분리되어 지면을 따라 슬라이딩될 때에 곡면부(72c)에 의해 슬라이딩홈부(72b)가 지면과 충돌되는 것을 방지할 수 있게 되어 제2기둥(14)이 후방으로 밀리면서 완충작용을 행하게 된다.Since the curved portion 72c is formed at the end of the sliding groove 72b to be curved when inclined upward, the curved portion 72c when the sliding groove 72b is separated from the connection panel 72a and slides along the ground. As a result, the sliding groove 72b can be prevented from colliding with the ground, and the second pillar 14 is pushed backward to perform a buffering action.
유동억제부(74)는, 지면에 설치되는 고정핀(74a)과, 고정핀(74a)에 연결되고 지지대(30)를 관통하여 연장되는 와이어(74b)와, 지지대(30)와 간섭되어 와이어(74b)가 지지대(30)를 통과하여 슬라이딩되는 것을 억제하도록 와이어(74b)에 설치되는 걸림고리부(74c)를 포함한다.The flow restraining portion 74 has a fixed pin 74a installed on the ground, a wire 74b connected to the fixed pin 74a and extending through the support 30, and interferes with the support 30. A hooking portion 74c provided on the wire 74b to prevent the 74b from sliding through the support 30 is included.
고정핀(74a)은 패널부재(50)의 단부, 즉 제1완충부(53)에 대향되는 지면에 설치되므로 차량 충돌이 발생되었을 때에 패널부(50)가 압축되는 방향과 반대 방향으로 와이어(74b)에 인장력을 제공하게 되고, 와이어(74b)에 설치되는 걸림고리부(74c)는 지지대(30)와 간섭되어 와이어(74b)가 지지대(30)에 형성되는 홀부를 따라 통과되는 것을 억제하게 된다.Since the fixing pin 74a is installed at the end of the panel member 50, that is, on the ground facing the first shock absorbing portion 53, when the vehicle collision occurs, the fixing pins 74a are connected in a direction opposite to the direction in which the panel 50 is compressed. Provide a tensile force to 74b), and the hooking portion 74c installed on the wire 74b interferes with the support 30 to inhibit the wire 74b from passing along the hole formed in the support 30. do.

레일부(80)는, 단부시설물의 전단부에 배치되도록 지면에 설치되며 베이스부(210)를 이루는 제1베이스패널(212)과, 단부시설물의 후단부에 배치되도록 지면에 설치되며 베이스부(210)를 이루는 제2베이스패널(214) 사이에 설치되는 복수 개의 와이어(86)와, 제2베이스패널(214)에 일체로 형성되는 배면패널(216)에 설치되고 와이어(86)의 후단부가 고정되는 배면고정패널(86a)과, 제1베이스패널(212)에 설치되고 복수 개의 와이어(86)의 전단부가 고정되는 고정축(84)을 포함한다.The rail unit 80 is installed on the ground so as to be disposed at the front end of the end facility, and comprises a first base panel 212 constituting the base 210, and is installed on the ground so as to be disposed at the rear end of the end facility. A plurality of wires 86 provided between the second base panel 214 constituting the 210 and the rear panel 216 integrally formed on the second base panel 214, the rear end of the wire 86 It includes a rear fixing panel 86a to be fixed, and a fixed shaft 84 installed on the first base panel 212 and fixed to front ends of the plurality of wires 86.
단부시설물의 전단부에 배치되는 제1베이스패널(212)에는 다수 개의 와이어(86)가 고정축(84)에 연결되고, 양단부에 배치되는 한 쌍의 와이어(86)는 배면고정패널(86a)까지 연장되어 고정된다.A plurality of wires 86 are connected to the fixed shaft 84 in the first base panel 212 disposed at the front end portion of the end facility, and the pair of wires 86 disposed at both ends are fixed to the rear panel 86a. It is extended until it is fixed.
단부시설물의 전단부에 배치되는 이동프레임(230)에는 감속부(90)가 설치되어 중앙부에 배치되는 와이어(86)가 감속부(90)를 통과하여 배면고정패널(86a)까지 연장되게 배치되고, 중앙부에 배치되는 이동프레임(230)에는 외측에 배치되는 한 쌍의 와이어(86) 사이의 간격을 벌리도록 한 쌍의 굴곡부재(36)가 설치된다.The moving frame 230 disposed at the front end of the end facility is provided with a reduction unit 90 so that the wire 86 disposed at the center portion extends through the reduction unit 90 to the rear fixing panel 86a. In the moving frame 230 disposed at the center portion, a pair of bending members 36 are installed to widen the interval between the pair of wires 86 disposed at the outside.
감속홈부는, 와이어(86)의 연장방향과 이격되도록 측 방향으로 경사지게 형성되어 제1경사부를 이루고, 감속돌기는, 저면이 하측 방향으로 경사지게 형성되어 제2경사부를 이루게 된다.The deceleration groove is formed to be inclined laterally to be spaced apart from the extending direction of the wire 86 to form a first inclined portion, and the deceleration protrusion is formed to be inclined in a downward direction to form a second inclined portion.
따라서 제1패널에 형성되는 한 쌍의 감속홈부 사이의 간격은 전단부 측 간격과 비교하여 후단부 측 간격이 더 넓게 형성되는 제1경사부를 이루게 되고, 감속돌기의 전단부는 후단부와 비교하여 짧게 형성되어 후단부로 갈수록 낮아지는 제2경사부를 이루게 된다.Therefore, the space between the pair of reduction gears formed in the first panel forms a first inclined portion having a wider space at the rear end side than the space at the front end side, and the front end of the reduction protrusion is shorter than the rear end. It is formed to form a second inclined portion is lowered toward the rear end.
상기한 바와 같은 제1경사부 및 제2경사부에 의해 제1패널과 제2패널(94) 사이의 간격으로 유입되는 와이어(86)는 양측 방향으로 벌어지면서 하측으로 낮아지게 통과 경로가 변경되고, 감속부(90)를 통과한 한 쌍의 와이어(86)는 한 쌍의 굴곡부재(36)에 의해 더 넓게 벌어지면서 통과하게 된다.As described above, the wire 86 introduced into the gap between the first panel and the second panel 94 by the first inclined portion and the second inclined portion is changed in both directions and lowered downward. , The pair of wires 86 passing through the deceleration part 90 are passed while being wider by the pair of bending members 36.
따라서 차량 충돌 시에 이동프레임(230) 및 감속부(90)가 후방으로 후퇴하게 되면 양측 방향으로 벌어지게 배치된 와이어(86)를 중앙부 측으로 모으면서 하측 방향으로 굴곡시키며 와이어(86)를 따라 슬라이딩되므로 이동프레임(230) 및 감속부(90)의 이동속도를 줄이면서 차량 충돌에 의한 충격을 감소시키는 효과가 나타나게 된다.Therefore, when the moving frame 230 and the reduction unit 90 retreat backwards during a vehicle collision, the wires 86 arranged in both directions are bent toward the center and bent downward to slide along the wires 86. Therefore, while reducing the moving speed of the moving frame 230 and the deceleration unit 90, the effect of reducing the impact due to the vehicle collision will appear.
또한, 전면패널(56)에는 운전자가 단부시설물을 인지하도록 하는 반사부재(56a)가 설치되며, 전면패널(56)의 하단에 형성되는 홈부를 통해 제1베이스패널(212)을 마감하는 커버부재(88)가 설치되므로 고정축(84)과 와이어(86) 사이의 연결구조를 커버할 수 있게 된다.In addition, the front panel 56 is provided with a reflective member 56a for allowing the driver to recognize the end facility, the cover member for closing the first base panel 212 through the groove formed in the lower end of the front panel 56 Since the 88 is installed, it is possible to cover the connection structure between the fixed shaft 84 and the wire 86.
또한, 본 실시예의 감속홈부는 제1패널의 상면에 복수 개의 감속블록을 설치하여 감속블록 사이의 간격이 감속홈부를 이루게 되므로 별도의 금형을 제작하여 감속홈부를 제작하는 것과 비교하여 감속홈부를 구비하는 제1패널을 용이하게 제작할 수 있게 된다.In addition, the deceleration groove part of the present embodiment is provided with a plurality of deceleration blocks on the upper surface of the first panel, so that the interval between the deceleration blocks forms a deceleration groove part, so that the reduction groove part is provided in comparison with the manufacture of a separate mold to produce a reduction mold. The first panel can be easily manufactured.
또한, 감속블록의 형상을 다양하게 가변시킬 수 있으므로 제1경사부의 경사 정도를 용이하게 변경하여 제작할 수 있게 되므로 와이어(86)가 감속홈부를 통과할 때에 감속되는 정도를 손쉽게 조절할 수 있게 된다.In addition, since the shape of the deceleration block can be changed in various ways, the degree of inclination of the first inclined portion can be easily changed and manufactured, so that the degree of deceleration when the wire 86 passes through the deceleration groove can be easily adjusted.
미설명 부호 216b는 제2베이스패널(214)과 배면패널(216) 또는 배면고정패널(86a)의 연결부위에 설치되는 보강리브(216b)이다. Reference numeral 216b denotes a reinforcing rib 216b installed at a connection portion between the second base panel 214 and the rear panel 216 or the rear fixing panel 86a.
