본 발명은 차량 충돌에 대해 기본적으로 소성변형 및 탄성변형이 발생되면서 다중분산으로 충격을 흡수 상쇄시킬수 있는 도로용 충격흡수대에 관한 것으로, 보다 상세하게는 충돌되는 차량에 대해 전방의 가드펜스가 먼저 자연스럽게 찌그러지면서 소성변형을 일으켜 충격을 1차 흡수하는 동시에, 중간의 인장흡수체와 함께 후방의 탄성흡수체가 인장변형 및 탄성변형되면서 미처 흡수되지 못한 차량의 충격을 분산 흡수하여 상쇄시켜 차량의 충격이 구조적으로 최소화될 수 있도록 한 차량충격이 다중분산되는 도로용 충격흡수대에 관한 것이다.The present invention relates to a road shock absorber that can basically offset the impact by multi-dispersion while the plastic deformation and elastic deformation occurs for the vehicle collision, more specifically, the front guard fence is naturally first to the impacted vehicle As it is distorted, it causes plastic deformation and absorbs the shock first, and the rear elastic absorber along with the middle tension absorber disperses and absorbs the shock of the vehicle that is not absorbed due to the tensile deformation and elastic deformation. It relates to a road shock absorber in which one vehicle shock is multi-dispersed so that it can be minimized.

일반적으로 도로 중앙의 중앙분리대 또는 도로 양측의 난간에는 차량이 충돌되면서 이탈되는 것을 방지하며, 차량 충돌시의 충격을 흡수시켜 차량을 보호하기 위한 충격흡수장치로서 가드펜스(가드레일)이라 불리우는 방호벽의 충격흡수대가 이들 중앙분리대 또는 난간을 구성하는 난간지주에 설치되고 있다.In general, the central divider in the middle of the road or the railings on both sides of the road prevents the vehicle from being separated and collides with it, and it is a shock absorber to protect the vehicle by absorbing the impact during the collision. Shock absorbers are installed in the handrails that make up these central separators or handrails.

이러한 충격흡수대는 통상 도로 중앙의 중앙분리대의 경우에는 상기 중앙분리대의 양측으로 모두 설치되며, 도로 양측의 난간인 경우에는 각각 도로쪽의 일측에만 설치되는 것이 보통이다.Such a shock absorber is usually installed on both sides of the central separator in the case of the central separator in the middle 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 난간지주에 설치된 가드펜스가 일정부분 찌그러지면서 차량의 충격을 흡수하게 되는데, 경우에 따라 차량의 충돌이 강할 때에는 충격흡수대를 구성하는 가드펜스는 물론 난간지주까지 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 fence installed on the railing holding against the collision of the vehicle, in some cases, when the collision of the vehicle is strong, the guard that constitutes the shock absorber The fence, of course, can not withstand the impact of the collision to the railings, leading to serious tragedy.

이와 같이 도로용 충격흡수대로서 난간지주에 설치되는 가드펜스는, 기본적으로 차량 충돌시의 충격하중을 흡수하여 운전자의 안전을 도모하는 동시에, 도로 밖으로 차량이 이탈되는 것을 차단시킬 수 있도록 구성됨이 당연하다.As described above, the guard fence installed on the railing brace as a road shock absorber is basically configured to absorb the impact load in the event of a vehicle collision, thereby enhancing the safety of the driver and to prevent the vehicle from leaving the road. .

그런데 지금까지 도로의 난간지주에 설치 구성된 충격흡수대를 보면, 차량 충돌시의 충격을 보다 효율적으로 흡수시켜 상쇄시킬 수 있도록 가드펜스의 내부를 충격흡수구조로서 개선시키고 있는 추세이며, 특히 차량 충돌시의 충격에 대해 가드펜스의 1차적인 충격 흡수만으로는 충분하지 못해 가드펜스와 난간지주 사이에 통상 탄성체인 별도의 간격유지재를 개재시켜, 차량 충돌시의 충격이 가드펜스의 찌그러짐에 의해 1차 흡수되는 동시에 간격유지재에 의해 2차 흡수되어 전체적으로 충격이 효과적으로 상쇄될 수 있도록 충격흡수대의 구조가 발전되고 있다.However, the shock absorbers installed on the railings of roads have been improving the interior of the guard fence as a shock absorbing structure in order to more efficiently absorb and offset the impact of the vehicle crash. The shock absorber's primary shock absorption alone is not sufficient for the impact, and the gap between the guard fence and the railing column is interposed between the guard fence and the railing column, so that the impact during the vehicle collision is primarily absorbed by the distortion of the guard fence. At the same time, the structure of the shock absorber is being developed so that the second absorbed by the spacer maintaining the shock can be effectively canceled as a whole.

그러나 기존의 도로용 충격흡수대는 차량의 충돌에 의한 충격이 상당히 큰 경우, 충돌되는 차량에 대해 가드펜스가 1차적으로 적절하게 찌그러지지 못하고 그대로 파손될 뿐만 아니라, 중간의 간격유지재 역시 탄성 반발력에 위한 접촉 충격을 정상적으로 발휘하지 못하고 함께 파손됨으로서 차량이 가드펜스를 넘어 이탈되는 심각한 대형사고로도 이어질 수 있는 구조적인 한계가 해결되지 못하고 있다.However, the existing road shock absorber is not only properly deflected firstly but also damaged as the impact caused by the collision of the vehicle, and the intermediate gap retaining material is also used for elastic repulsion. The structural limitations that can lead to serious catastrophic accidents, in which the vehicle breaks over the guard fence, are not solved due to failure of normal contact shocks.

본 발명은 지금까지의 도로용 충격흡수대에서 기대하기 힘들었던 차량 충돌시의 강한 충격에 견딜 수 있도록 차량의 충격이 구조적으로 보다 확실하게 분산 상쇄될 수 있도록 새로운 차량충격 흡수구조의 도로용 충격흡수대를 제공하고자 하는바, 충돌되는 차량의 충격에 대해 1차적으로 자연스럽게 소성변형되면서 충격을 흡수하며 비교적 충격의 강도가 클 경우에도 소성변형과 함께 2차적으로 인장변형 및 탄성변형으로 충격을 다중분산시켜 상쇄되도록 함으로서, 차량 충돌시의 충격이 다중으로 분산 흡수되어 최소화될 수 있는 새로운 충격흡수 구조체로서의 차량충격이 다중분산되는 도로용 충격흡수대를 제공함에 그 목적이 있다.The present invention provides a road shock absorber for a new vehicle shock absorber structure so that the impact of the vehicle can be more reliably dispersed and canceled structurally to withstand the strong shock in the event of a vehicle crash that was difficult to be expected in the road shock absorber until now. It is intended to absorb the impact while naturally plastically deforming the impact of the colliding vehicle, and even if the strength of the impact is relatively large, the plastic deformation and the secondary deformation by the multi-dispersion of the impact by the tensile and elastic deformation so as to cancel out. Accordingly, an object of the present invention is to provide a shock absorber for a road in which a vehicle shock is multi-dispersed as a new shock absorbing structure that can be minimized by absorbing and scattering multiple impacts during a vehicle crash.

이러한 목적을 달성하기 위한 본 발명의 차량충격이 다중분산되는 도로용 충격흡수대는, 기본적으로 도로의 중앙 또는 양측에 통상 지주받침대를 매개로 일정간격마다 설치 고정되는 난간지주와, 상기 난간지주의 한쪽 또는 양쪽으로 결합 고정되는 일측이 개방되어 내부가 가드요부로 형성되어 차량 충돌시에 소성변형되는 가드펜스와, 상기 난간지주에 중앙의 지지부가 볼트결합되면서 상기 지지부 양측으로 곡면지게 절곡된 탄성부가 돌출되어 차량 충돌시에 탄성변형되는 탄성흡수체와, 상기 가드펜스의 가드요부와 탄성흡수체 양쪽의 탄성부 사이에 지지볼트를 매개로 볼트결합되어 차량 충돌시에 인장변형될 수 있도록 양쪽으로 지지장공이 관통 형성된 인장흡수체를 포함하여 구성된다.In order to achieve the above object, the road shock absorber for multi-dispersion of the vehicle shock of the present invention is basically a handrail holder fixed at regular intervals through a support base on the center or both sides of the road, and one side of the handrail holder. Alternatively, one side coupled to both sides is opened and the inside is formed as a guard recess, and the guard fence is plastically deformed at the time of a vehicle crash, and the elastic part bent to both sides of the support part is bolted as the support part of the center is bolted to the railing column. The support hole is penetrated to both sides so that the elastic absorber is elastically deformed at the time of a vehicle crash, and the support bolt is bolted between the guard recess of the guard fence and the elastic parts of both sides of the elastic absorber so as to be tensilely deformed at the time of the vehicle crash. It comprises a tension absorber formed.

특히 가드펜스는 차량 충돌시의 충격에 따라 균등한 소성변형이 발생되어 충격을 흡수할 수 있도록 알루미늄강판으로 형성된다.In particular, the guard fence is formed of an aluminum steel sheet so that even plastic deformation occurs according to the impact of the vehicle collision to absorb the impact.

이하, 본 발명의 구조 개선된 도로용 충격흡수대의 구체적인 구성관계 및 작용을 첨부된 바람직한 실시예의 도면을 참조하여 상세히 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific structural relations and functions of the road shock absorber for improved structure of the present invention will be described in detail with reference to the accompanying drawings.

도 1과 도 2는 본 발명의 충격흡수대가 난간지주(10)에 설치된 결합상태의 외부구조와 단면구조를 각각 도시한 것이고, 도 3과 도 4는 본 발명의 충격흡수대 가 난간지주(10)에 설치되기 전의 분리상태와 상하 이중으로 설치된 결합상태를 각각 도시한 것이다.1 and 2 show the external structure and the cross-sectional structure of the shock absorbing table of the present invention is installed in the handrail holding 10, respectively, Figures 3 and 4 are the shock absorbing table handrail holding 10 of the present invention. It shows the separated state before the installation and the coupling state installed in the upper and lower double respectively.

도면에서 보는 것처럼, 본 발명에 따라 차량 충돌시의 충격을 소성변형 및 탄성변형은 물론 인장변형을 통한 다중분산으로 구조적으로 보다 확실하게 흡수 상쇄시킬수 있도록 구성되는 도로용 충격흡수대는, 기본적으로 도로의 중앙 또는 양측에 통상 지주받침대(16)를 매개로 일정간격마다 설치 고정되는 난간지주(10)와, 상기 난간지주(10)의 한쪽 또는 양쪽으로 결합 고정되는 일측이 개방되어 내부에 인장흡수체(30) 및 탄성흡수체(40)가 위치하게 되는 가드요부(24)의 공간을 형성하여 차량 충돌시에 1차적으로 소성변형되는 가드펜스(20)를 포함하여 구성된다.As shown in the drawings, the road shock absorber configured to be able to more effectively offset the shock during the vehicle collision by the plastic deformation and elastic deformation as well as the multi-dispersion through the tensile deformation is basically a road of Balustrade column 10 is fixed to the center or both sides installed at regular intervals via the support base 16, and one side coupled to one or both sides of the balustrade column 10 is open to the tension absorber (30) ) And a guard fence 20 which forms a space of the guard recess 24 in which the elastic absorber 40 is positioned and is primarily plastically deformed at the time of a vehicle crash.

그리고 가드펜스(20)와 난간지주(10) 사이에 인장흡수체(30)와 함께 설치고정되어 차량 충돌시 탄성변형을 일으키게 되는 탄성흡수체(40)는 판상인 중앙의 지지부(42)가 상기 난간지주(10)에 대해 고정볼트(46)를 매개로 볼트고정되며, 상기 지지주(42)를 중심으로 양측으로 곡면지게 절곡된 탄성부(44)는 별도의 인장변형체(30)와 함께 상기 가드펜스(20)의 가드요부(24)에 지지볼트(34)를 매개로 결합지지된다.In addition, the elastic absorber 40 is fixed between the guard fence 20 and the railing support 10 together with the tension absorber 30 to cause elastic deformation during the collision of the vehicle. The bolt is fixed to the fixing bolt 46 with respect to (10), the elastic portion 44 bent to both sides around the support column 42 is the guard fence with a separate tensile deformation (30) The guard recess 24 of the 20 is coupled and supported by the support bolt 34.

즉, 탄성흡수체(40)는 중앙의 지지부(42)가 평평한 판상이면서 양측으로 곡면지게 절곡되어 양측이 다시 중앙쪽으로 평평한 판상으로 탄성부(44)가 절곡된 형태를 이루게 되는데, 이는 가드펜스(20)를 거쳐 탄성흡수체(40)로 전달되는 차량의 충격이 상기 탄성흡수체(40) 양측의 탄성부(44)에 의해 순간적으로 탄발동작되면서 충격을 흡수 상쇄시킬 수 있도록 한다.That is, the elastic absorber 40 is bent in a flat plate-like and curved to both sides in the center of the support portion 42 to form a form in which the elastic portion 44 is bent in a flat plate toward both sides, which is a guard fence (20) The impact of the vehicle transmitted to the elastic absorber 40 through the) is instantaneously shot by the elastic parts 44 on both sides of the elastic absorber 40 to offset the shock.

그리고 탄성흡수체(40) 중앙의 지지부(42)는 난간지주(10)의 볼트공(12)과 같이 해당 볼트공(43)이 관통되어 고정볼트(46)의 체결로서 쉽게 결합고정될 수 있으며, 상기 탄성흡수체(40) 양측의 탄성부(44) 역시 각각 볼트공(44)이 관통되어 인장흡수체(30)의 지지장공(32)과 가드펜스(20)의 볼트공(22)에 대해 체결되어 결합고정된다. 물론 상기 양쪽의 탄성부(44)에도 볼트공(45)이 형성됨은 당연하다.In addition, the support 42 in the center of the elastic absorber 40 may be easily coupled and fixed as a fastening of the fixing bolt 46 through the corresponding bolt hole 43, like the bolt hole 12 of the railing column 10. The elastic parts 44 at both sides of the elastic absorber 40 are also fastened to the bolt holes 44 through the support holes 32 of the tension absorber 30 and the bolt holes 22 of the guard fence 20. Is fixed. Of course, the bolt hole 45 is also formed in the elastic portion 44 of both sides.

특히 차량 충돌시의 충격에 대해 1차적으로 소성변형되는 가드펜스(20)의 경우, 차량 충돌시의 충격에 따라 균등한 소성변형이 발생되도록 알루미늄강판으로 형성됨이 바람직하다.In particular, in the case of the guard fence 20 which is primarily plastically deformed with respect to the impact at the time of the vehicle collision, it is preferable that the guard fence 20 is formed of an aluminum steel sheet so that an even plastic deformation occurs according to the impact during the vehicle collision.

그리고 차량 충돌시의 충격에 대해 2차적으로 탄성흡수체(40)의 탄성변형과 함께 상기 탄성흡수체(40) 및 가드펜스(20)를 매개로 인장변형되면서 차량의 충격을 보다 다중분산시킬 수 있도록 이들 사이에 판상의 인장흡수체(30)가 설치되는데, 상기 인장흡수체(30)는 상기 탄성흡수체(40) 양측의 탄성부(44)에 관통된 볼트공(45)과 상기 가드펜스(20)의 가드요부(24)에 관통된 볼트공(22)으로 체결되는 지지볼트(34)가 통과되어 차량 충돌시의 충격강도에 따라 적절하게 인장변형될 수 있도록 양쪽으로 지지장공(32)이 관통된다.In addition to the elastic deformation of the elastic absorber 40 and the tensile deformation through the elastic absorber 40 and the guard fence 20 with respect to the impact during the vehicle collision, so that the impact of the vehicle can be more multi-dispersed Between the plate-shaped tension absorber 30 is installed, the tension absorber 30 is a guard of the bolt hole 45 and the guard fence 20 penetrated through the elastic portion 44 on both sides of the elastic absorber 40 The support bolts 34, which are fastened by the bolt holes 22 penetrated by the recesses 24, pass through the support holes 32 on both sides so that the support bolts 34 may be properly deformed according to the impact strength during the collision of the vehicle.

즉, 인장흡수체(30) 양쪽의 지지장공(32)은 탄성흡수체(40)의 볼트공(44) 및 가드펜스(20)의 볼트공(22)과 달리 장방형태로 길게 형성됨으로서, 차량 충돌시에 전달되는 충격강도에 따라 양쪽의 탄성흡수체(40)와 가드펜스(20) 사이의 상기 인장흡수체(30)가 지지볼트(34)를 매개로 적절하게 위치변경되면서 충격을 흡수하게 되는 인장변형 구조체를 이루게 된다.That is, the support holes 32 on both sides of the tension absorber 30 are formed to have a long shape, unlike the bolt holes 44 of the elastic absorber 40 and the bolt holes 22 of the guard fence 20, so that the vehicle crashes. According to the impact strength transmitted to the tension absorber 30 between the elastic absorbent body 40 and the guard fence 20 of both sides of the tension deformation structure to absorb the shock while properly changing the position via the support bolt 34 Will be achieved.

아울러 난간지주(10)는 지주받침대(16)를 매개로 고정볼트(14)로 도로에 대해 결합고정되며, 특히 본 발명의 충격흡수대를 구성하게 되는 가드펜스(20)와 탄성흡수체(40) 및 인장흡수체(30)는 상기 난간지주(10)에 대해 길이방향으로 한쪽 또는 양쪽 모두에 설치됨으로서 차량 충돌시의 충격을 흡수 및 차량의 이탈을 방지하게 되는 통상의 도로난간 또는 중앙분리대를 구성하게 된다.In addition, the handrail holding 10 is fixed to the road by a fixed bolt 14 via the support base 16, the guard fence 20 and the elastic absorber 40 and constitute a shock absorber of the present invention in particular The tension absorber 30 is installed on one or both sides in the longitudinal direction with respect to the handrail holder 10 to constitute a conventional road railing or a center separator that absorbs a shock during a vehicle collision and prevents the vehicle from being separated. .

이와 같이 구성되는 본 발명의 차량충격이 다중분산되는 도로용 충격흡수대는 도 3의 단면구조에서 보는 것처럼, 도로를 주행하는 차량이 사고로 난간지주(10)에 충돌하게 되면 먼저 바깥쪽에 위치하는 가드펜스(20)가 충돌시의 충격강도에 따라 1차적으로 자연스럽게 찌그러지면서 소형변형을 일으켜 충격을 흡수하게 된다.As shown in the cross-sectional structure of FIG. 3, the road shock absorber for multi-dispersion of the vehicle shock of the present invention configured as described above, when the vehicle traveling on the road accidentally collides with the railing column 10, is located outside the guard. The fence 20 is naturally distorted according to the impact strength at the time of collision, causing a small deformation to absorb the impact.

그리고 1차 가드펜스(20)에 의해 흡수되지 못한 차량의 충격은 다시 가드펜스(20) 내측과 난간지주(10) 외측에 설치된 인장흡수체(30)와 탄성흡수체(40)에 의해 계속해서 흡수되어 상쇄하게 되는데, 상기 가드펜스(20)의 소성변형에 의해 1차 흡수되는 차량의 충격은 계속해서 상기 탄성흡수체(40)를 중심으로 상기 인장흡수체(30)가 지지장공(32)을 통해 자연스럽게 위치변경되면서 인장변형이 발생되며, 동시에 상기 인장흡수체(30)와 함께 상기 탄성흡수체(40)의 양쪽 탄성부(44a)가 순간적으로 뒤로 휘어졌다가 원위치로 탄발 복귀되면서 차량의 충격을 흡수하여 보다 확실하게 상쇄시키게 된다.In addition, the impact of the vehicle that is not absorbed by the primary guard fence 20 is continuously absorbed by the tension absorber 30 and the elastic absorber 40 installed inside the guard fence 20 and the railing support 10. The tension absorber 30 is naturally positioned through the support hole 32 about the elastic absorber 40 while the impact of the vehicle absorbed primarily by the plastic deformation of the guard fence 20 continues to be offset. Tensile deformation occurs while being changed, and at the same time, both elastic portions 44a of the elastic absorber 40 together with the tension absorber 30 are bent backwards momentarily and returned to their original positions, thereby absorbing the impact of the vehicle and thus more reliably. Canceled out.

결국 본 발명의 도로용 충격흡수대로 충돌되어 전달되는 차량의 충격은 기본적으로 가드펜스(20)의 소성변형에 의해 자연스럽게 흡수되며, 상대적으로 강한 충 격이더라도 상기 가드펜스(20)와 함께 인장변형되는 인장흡수체(30) 및 탄성변형되는 탄성흡수체(40)에 의해 추가적으로 충격을 흡수하여 상쇄시킴으로서, 차량 충돌시에 발생되는 충격에 대해 구조적으로 보다 확실하게 흡수하여 상쇄시킬 수 있어 차량의 보호는 물론 도로 밖으로의 차량의 이탈도 효과적으로 방지할 수 있다.Eventually, the impact of the vehicle transmitted by colliding with the shock absorber for the road of the present invention is naturally absorbed by the plastic deformation of the guard fence 20, and the tensile deformation with the guard fence 20 even if the impact is relatively strong. By absorbing and offsetting the shock by the tension absorber 30 and the elastic absorber 40 elastically deformed, it is possible to structurally more reliably absorb and offset the shock generated during a vehicle crash, thereby protecting the road as well as protecting the road. The departure of the vehicle outside can also be effectively prevented.

이상에서와 같이, 본 발명의 차량충격이 다중분산되는 도로용 충격흡수대는 충돌되는 차량의 충격이 자연스럽게 가드펜스의 소성변형에 의해 1차적인 흡수되면서 동시에 인장흡수체 및 탄성흡수체를 통해 인장변형 및 탄성변형에 의해 2차적으로 분산 상쇄될 수 있도록 구조 개선됨으로서, 지금까지의 도로용 충격흡수대가 충분하게 발휘되지 못한 강한 충격에도 구조적으로 견딜 수 있을 뿐만 아니라 차량의 충격이 구조적으로 보다 확실하게 분산 흡수되어 최소화될 수 있으며, 또한 차량이 도로 밖으로 이탈되는 것도 당연히 억제시킬 수 있는 새로운 충격흡수 구조체로서의 작용효과를 제공할 수 있을 것으로 기대된다.As described above, the road shock absorber for multi-dispersion of the vehicle impact of the present invention is the primary shock absorbed by the plastic deformation of the guard fence naturally while at the same time tensile strain and elastic through the tensile absorber and elastic absorber By improving the structure so that it can be partially canceled by deformation, it can not only structurally withstand the strong impact that the road shock absorber has not been sufficiently exhibited until now, but also the impact of the vehicle is more reliably distributed and absorbed structurally. It is expected that it can be minimized and also provide an effect as a new shock absorbing structure that can of course also prevent the vehicle from leaving the road.
