상기 도시된 바와 같이 차량충격 흡수장치(10) 전면에는 반원형의 전면고무판(20)가 놓여 있으며, 이 전면고무판(20)후방에는 볼트와 너트로 연결된 한조의 1,2단위체고무판(30, 30′)이 순차적으로 부착되어 있는 것으로서, 상기 전면고무판(20)과 1, 2단위체고무판(30, 30′)은 충격흡수부재로 되어있다.As shown in the drawing, a semi-circular front rubber plate 20 is placed on the front of the vehicle shock absorber 10, and a set of 1,2 unit body rubber plates 30 and 30 'connected to the rear of the front rubber plate 20 by bolts and nuts. ) Are sequentially attached, the front rubber plate 20 and the 1, 2 unit body rubber plate (30, 30 ') is a shock absorbing member.
상기 전면고무판(20)과 1, 2단위체고무판(30, 30′)사이에 삽입된 보강용리브(40)내부에는 복수개의 스틸플레이트(50)가 일정한 간격으로 매입하되 하부층에 있는 스틸플레이트(51)저면에는 요홈(52)이 형성되어 있어 노면에 앙카볼트(61)로 고정된 레일(60)상에 놓이도록 하여 차량충돌시 차량충격 흡수장치(10)가 후방으로 이동할 수 있도록 안내하는 수단을 가지며, 상기 복수개의 스틸플레이트(50, 51)는 충격에 의한 충격에너지를 단위체인 1, 2단위체고무판(30, 30′)으로 전달하는 수단을 갖는 것이다.Inside the reinforcing rib 40 inserted between the front rubber plate 20 and the one and two unit rubber plates 30 and 30 ', a plurality of steel plates 50 are inserted at regular intervals, but the steel plate 51 in the lower layer. A groove 52 is formed at the bottom thereof so that the vehicle shock absorbing device 10 can be moved to the rear when the vehicle is crashed by being placed on the rail 60 fixed to the anchor bolt 61 on the road surface. The plurality of steel plates (50, 51) has a means for transferring the impact energy due to the impact to the unit body 1, 2 unit rubber plates (30, 30 ').
또한 스틸플레이트(50, 51)를 감싸고 있는 보강용리브(40)는 충격에 의해 스틸플레이트(50, 51)가 파손을 최소화 하는 수단을 갖는 것이다.In addition, the reinforcing rib 40 surrounding the steel plates 50 and 51 has a means for minimizing the breakage of the steel plates 50 and 51 by the impact.
상기 1, 2단위체고무판(30, 30′)내향으로는 파형스틸판(70)이 형성되어 있어 전면고무판(20)과 1, 2단위체고무판(30, 30′)자체의 충격감쇄효과에 의해서 흡수되며, 전면고무판(20)과 1, 2단위체고무판(30, 30′) 각각의 내부 공간에는 전면고무판(20)과 1, 2단위체고무판(30, 30′)과 같은 재질의 충격흡수부재(80)가 놓이게 된다.The corrugated steel plate 70 is formed inwardly of the 1, 2 unit rubber plates 30 and 30 'and absorbed by the impact damping effect of the front rubber plate 20 and the 1 and 2 unit rubber plates 30 and 30' itself. In the inner space of each of the front rubber plate 20 and the one and two unit rubber plates 30 and 30 ', an impact absorbing member 80 made of the same material as the front rubber plate 20 and the one and two unit rubber plates 30 and 30'. ) Is placed.
상기 2단위체고무판(30′)후방에는 모든 도로상의 중앙분리대 시작점과 고속도로 분기점, 터널입구, 교량의 시작점의 콘크리트방벽(90) 또는 "H"빔과 같은 고정물에 앙카볼트(91)로 고정될 수 있도록 한다.Behind the two-unit body rubber plate (30 ') can be secured with anchor bolts (91) to the fixtures, such as the concrete barrier 90 or "H" beam of the central divider start point and highway junction, tunnel entrance, bridge start point on all roads Make sure
그리고 상기 전면고무판(20)과 1, 2단위체고무판(30, 30′)각각의 내부 공간에는 스폰지부재(81), 물주머니(82) 또는 모레주머니(83)등이 놓이게 된다.In addition, a sponge member 81, a water bag 82, or a moire bag 83 and the like are placed in the inner space of each of the front rubber plate 20 and the one and two unit rubber plates 30 and 30 '.
상기와 같이 구성된 본 발명은 모든 도로상의 중앙분리대 시작점과 고속도로분기점, 터널입구, 교량의 시작점의 콘크리트방벽(90) 또는 "H"빔과 같은 고정물의 노면에 레일(60)을 앙카볼트(61)로 고정시키고 반원형의 전면고무판(20)가 전면에 배치되도록 상기 레일(60)상에 놓이게 된다.According to the present invention configured as described above, the rail 60 is anchored to the road surface of a fixture such as a concrete barrier 90 or a "H" beam at the center divider starting point and highway junction, tunnel entrance, and bridge starting point on all roads. And the semi-circular front rubber plate 20 is placed on the rail 60 so as to be disposed at the front.
이때 하부층에 있는 스틸플레이트(51)의 요홈(52)이 레일(60)상에 놓이게 된다.At this time, the groove 52 of the steel plate 51 in the lower layer is placed on the rail (60).
또한 2단위체고무판(30′)후방은 고정물 콘크리트방벽(90)또는 "H"빔에 앙카볼트(91)로 고정시킨 상태에서 차량이 정면에서 전면고무판(20)과 충돌하게 되면, 충격흡수능력이 큰 전면고무판(20)과 1, 2단위체고무판(30, 30′)자체의 충격감쇄효과에 의해서 흡수되며, 파형스틸판(70)의 변형에너지 의해 차량충격 흡수장치(10)는 수축된다.In addition, when the vehicle collides with the front rubber plate 20 at the front while the two unit rubber plate 30 'is fixed to the fixed concrete barrier 90 or the "H" beam with an anchor bolt 91, the shock absorbing ability is reduced. It is absorbed by the impact damping effect of the large front rubber plate 20 and the one and two unit rubber plates 30 and 30 'itself, and the vehicle shock absorber 10 is contracted by the strain energy of the corrugated steel plate 70.
이때 하부층에 있는 스틸플레이트(51)는 레일(60)의 안내에 따라 후방으로 슬라이드되어 차량충격 흡수장치(10) 측면으로 이탈되거나 비산되는 것을 막아 2차사고의 위험을 예방할 수 있다.At this time, the steel plate 51 in the lower layer is slid backwards according to the guide of the rail 60 to prevent it from being separated or scattered to the side of the vehicle shock absorber 10 can prevent the risk of secondary accidents.
또한 파형스틸판(70)은 충돌에 의해 소성변형되므로 변형된 1, 2단위체고무판(30, 30′)의 회복력을 억제하여 1, 2단위체고무판(30, 30′)의 반발력에 의해 차량이 튕겨져 나가는 것을 방지하므로, 2차사고의 유발을 억제할 수 있다.In addition, since the corrugated steel plate 70 is plastically deformed by a collision, the vehicle is bounced by the repulsive force of the one and two unit rubber plates 30 and 30 'by suppressing the recovery force of the deformed one and two unit rubber plates 30 and 30'. Since it prevents the outgoing, it is possible to suppress the occurrence of secondary accidents.
충돌 후에는 변형된 파형스틸판(70)만을 교체하여 전면고무판(20)과 1, 2단위체고무판(30. 30′)을 재사용이 가능하도록 하였다.After the collision, only the deformed corrugated steel plate 70 was replaced so that the front rubber plate 20 and the one and two unit rubber plates 30.30 'could be reused.
또한 고속도로와 같이 충돌에너지가 큰 분기점의 콘크리트 방벽에는 일반도로와 달리 1, 2단위체고무판(30, 30′)이외에 또 같은 단위체고무판을 복수개로 연장 설치할 수 있도록 하였다.In addition, unlike the general road, the concrete barrier at the junction where the impact energy is high, such as a highway, can be installed in addition to one or two unit rubber plates (30, 30 ') and a plurality of unit rubber plates.
이상에서 설명한 바와 같이 본 발명은 차량충격용 흡수장치의 설치길이 조절이 용이하게 하여 다양한 충돌속도에 대처 가능하며, 변형 후 본래의 모양으로 복귀하려는 충격흡수시설의 회복력에 의한 반발력을 최소화하여 충돌에 의해 발생되는 충격을 효과적으로 흡수하고 시설물의 파괴와 인명피해를 방지하며, 2차 사고를 방지할 수 있는 안정적인 시설을 제공함은 물론 설치, 보수, 관리가 용이하고 재활용이 가능한 효과등을 갖고 있다.As described above, the present invention can cope with various collision speeds by easily adjusting the installation length of the shock absorber for a vehicle shock, and minimizes the repulsive force due to the resilience of the shock absorbing facility to return to its original shape after deformation. It effectively absorbs the shocks generated, prevents destruction of facilities and damages to life, provides stable facilities to prevent secondary accidents, and is easy to install, repair, manage and recycle.
