Description
본 발명은 도로에서 차의 사고 방지 또는 차도와 인도와의 칸막이로 설치되는 가드레일의 설치방법에 관한 것으로서, 더욱 상세하게는, 포스트(지주)와 판넬형태의 펜스 사이에 충격흡수용의 스프링과 흡수구를 설치하여, 차량이 가드레일에 충돌될 때, 스프링이 압축되거나 흡수구가 변형되도록 하여 펜스를 통해 차량에 되전달되는 충돌시의 반발력을 줄여 줌으로서, 반발력에 의해 차량이 좌우로 흔들리다가 전복된다든지 또는 다른 차선으로 되튕겨져 올라가서 후속차량과 충돌되는 일이 없도록 한, 가드레일의 설치방법에 관한 것이다.The present invention relates to a method for installing a guardrail installed in a road preventing a car accident or a partition between a roadway and a sidewalk, and more specifically, a spring for shock absorption between a post (holder) and a fence in the form of a panel. When the absorber is installed, the spring is compressed or the absorber is deformed when the vehicle collides with the guard rail, thereby reducing the repulsive force in the event of a collision transmitted back to the vehicle through the fence. A method of installing a guardrail is to prevent the vehicle from being rolled over or bounced back into another lane to collide with a subsequent vehicle.
본 발명이 속하는 기술분야의 종래 기술로서는, 예컨대 도 5와 도 6, 그리고 본 출원인의 선출원 특허 98-32894호(도 4참조) 등이 공지되어 있다.As the prior art in the technical field to which the present invention pertains, for example, FIGS. 5 and 6, and the applicant's prior application patent 98-32894 (see FIG. 4) and the like are known.
이 중, 도 5에 도시된 가드레일(guardrail)은, 가장 널리 알려진 종래 가드레일의 설치상태를 나타낸 종단면도로서, 상기 도면에 의하면, 하단부가 콘크리트 구조물 속에 고정된 포스트(1)와, 상기 포스트(1)의 상단부에 고정되는 소정 형상의 펜스(2)와, 상기 펜스(2) 및 포스트(1)를 일체로 고정시키는 체결볼트(3) 및 고정너트(6)로 구성되었다.Of these, the guardrail shown in Figure 5 is a longitudinal cross-sectional view showing the installation state of the most well-known conventional guardrail, according to the drawing, the post (1) the lower end is fixed in the concrete structure, and the post It consists of a fence (2) of a predetermined shape fixed to the upper end of (1), and a fastening bolt (3) and a fixing nut (6) for integrally fixing the fence (2) and the post (1).
그러나, 이와 같은 구성의 가드레일은 차량과의 충돌시, 가드레일의 펜스 쪽이 받는 충격력만큼의 반발력이 차량에 되작용되어, 차량이 전복되거나 다른 차선으로까지 되튕겨져 또다른 사고를 발생하게 되는 단점이 있었다.However, the guardrail of such a configuration, when the collision with the vehicle, the repulsion force as much as the impact force received by the fence side of the guardrail acts on the vehicle, causing the vehicle to be rolled over or bounced back to another lane, causing another accident. There was a downside.
이러한 상기 도 5에 도시된 가드레일의 문제점을 개선하기 위해, 다수개의 폐타이어(21)를 상하로 배설한 후, 그들의 접합되는 부분을 볼트·너트 형태의 연결요소(22)로 체결하여 완충물(20)을 만들고, 이 완충물의 내부에 소정의 충전재(23)를 부어 만든 것이 있었지만(도 6참조), 상기 구성의 가드레일(방호물)은 중량이 대단히 무겁고, 또한 제작 및 설치에 많은 노력이 필요하다는 단점이 있었다.In order to improve the problem of the guard rail shown in FIG. 5, the plurality of waste tires 21 are disposed up and down, and then the parts to be joined are fastened to the connecting elements 22 in the form of bolts and nuts to be cushioned. (20) was made, and a predetermined filler 23 was poured into the buffer (see Fig. 6), but the guardrail (guard) of the above-described structure was very heavy, and a lot of effort was made in manufacturing and installation. There was a disadvantage that this was necessary.
이에 본 출원인은 상기 도 5와 도 6에 제시된 가드레일의 문제점들을 개선하기 위해, 선출원 특허 98-32894호(도 4참조)에서 신규의 가드레일을 제안한 바 있는데, 그의 기재내용을 살펴보면, 소정 두께의 강판을 벤딩하여 만든 통상의 펜스(2)와, 이 펜스(2)가 상단부분에 고정되는 통상의 포스트(1)와, 이들 펜스(2)와 포스트(1)에 형성되어 있는 볼트 구멍에 끼워져서 이들을 일체화 하는 체결볼트(3)와, 상기 체결볼트(3)의 나사부 끝단 쪽에 나사식으로 체결되거나 또는 용접되어 상기 체결볼트(3)가 포스트(1)에서 분리되지 않도록 하는 고정너트(6)로 구성되는 가드레일의 설치방법에 있어서, 상기 펜스(2)의 전면쪽 중앙부에 작은 크기의 요홈을 길이방향으로 형성하여 이 부분에 반사 테이프(7)를 부착하고, 상기 펜스(2)와 포스트(1) 사이의 볼트 나사부에는 먼저 소정형상의 와셔를 끼운 후, 차례대로 스프링(4)과 통상의 와셔(5a)를 끼워서 구성되도록 되어 있다.In this regard, the present applicant has proposed a new guardrail in Patent Application No. 98-32894 (see FIG. 4) in order to improve the problems of the guardrail shown in FIGS. 5 and 6. A common fence 2 made by bending a steel sheet of a steel plate, a normal post 1 to which the fence 2 is fixed at an upper end portion thereof, and bolt holes formed in these fences 2 and posts 1 A fastening bolt 3 which is fitted to integrate them, and a fastening nut 6 which is screwed or welded to the threaded end of the fastening bolt 3 so that the fastening bolt 3 is not separated from the post 1; In the installation method of the guard rail consisting of a), a small groove is formed in the longitudinal center portion of the front side of the fence (2) in the longitudinal direction, and the reflective tape (7) is attached to this portion, and the fence (2) and The bolt thread between the posts (1) is far from By inserting a washer having a predetermined shape, in turn, it is configured to be sandwiched between the spring 4 and an ordinary washer (5a).
그러나, 상기 본 출원인의 선출원 특허 98-32894호에서 제안하는 방법으로 가드레일을 설치하게 되면, 차량과 가드레일이 충돌했을 때의 충격력을 스프링(4)으로 적당히 흡수 분산시켜 차량에 되작용되는 반발력이 줄어들게 됨으로, 반발력에 의해 차량이 전복되거나 다른 차선으로까지 되튕겨져 올라가 또다른 사고를 유발하는 문제점을 해소할 수 있지만, 차량이 비스듬히 충돌될 때에는 스프링(4)에 의한 충격완화 효과가 낮고, 특히 포스트(1) 사이가 멀수록 펜스(2)가 직접 부담하게 되는 충격력이 커서, 자칫 차량이 펜스를 넘어가 버리는 경우가 있을 수도 있다는 단점이 예측되었다.However, when the guardrail is installed by the method proposed by the applicant's prior application No. 98-32894, the repulsive force acting on the vehicle by absorbing and dispersing the impact force when the vehicle and the guardrail collide with the spring 4 is appropriate. By reducing this, the problem of causing the vehicle to be overturned or rebounded to another lane by the repulsive force to cause another accident can be solved, but when the vehicle collides at an angle, the impact mitigation effect by the spring 4 is low, especially As the distance between the posts 1 increases, the impact force directly applied to the fence 2 is large, and it is predicted that the vehicle may sometimes pass over the fence.
본 발명은 상기의 문제점을 개선하기 위해 안출된 것으로서, 차량이 펜스와 비스듬히 충돌하더라도 그때의 충격력을 충분히 흡수하여 펜스 쪽이 변형되는 에너지로 발산시키고, 그러면서도 펜스가 완전히 부서지거나 찢어지는 일이 없도록 하여 차량이 추락하는 이차적인 사고를 예방할 있도록 하는 가드레일의 설치방법을 제공함에 목적이 있다.The present invention has been made in order to solve the above problems, even if the vehicle collides with the fence at an angle, absorbs the impact force at that time enough to diverge the energy of the fence side, and yet the fence is not completely broken or torn It is an object of the present invention to provide a method of installing a guardrail to prevent secondary accidents in which a vehicle falls.
상기의 목적을 달성하기 위해서, 본 발명에서는 다음과 같은 수단을 강구하였다. 즉, 본 발명에서는, 통상의 펜스와, 이 펜스가 고정되는 통상의 포스트와, 이들을 일체화 하는 체결볼트와, 상기 체결볼트가 포스트에서 분리되지 않도록 하는 고정너트로 구성되는 가드레일의 설치방법에 있어서, 상기 펜스의 전면쪽 중앙부에 작은 크기의 요홈을 길이방향으로 형성하여 이 부분에 반사 테이프를 부착하고, 상기 펜스와 포스트 사이에 소정 형상의 충격흡수구를 위치시킨 후 상기 충격흡수구의 중앙쪽 장공과 상기 포스트에 형성된 볼트구멍 및 펜스에 형성된 볼트구멍을 체결볼트로 관통 결합시켜서 이 체결볼트의 나사부에 스프링 등을 외삽함과 동시에 상기 충격흡수구의 좌우측편에 형성되어 있는 보조 볼트구멍과 펜스의 볼트구멍을 지지볼트로 관통시켜 각 볼트들의 나사부 끝에 너트를 채워서 구성하였다.In order to achieve the above object, the following means have been devised in the present invention.

도 1과 도 2는 본 발명의 방법에 따라서 설치된 가드레일의 측면도와 그의 설치상태를 나타내는 분해 사시도이다.1 and 2 are exploded perspective views showing a side view of the guardrail installed in accordance with the method of the present invention and the installation state thereof.
상기의 도면을 통해 알 수 있는 바와 같이, 본 발명에서는, 소정 두께의 강판을 벤딩하여 만든 통상의 펜스(2)와, 이 펜스가 상단부분에 고정되는 통상의 포스트(1)와, 이들 펜스(2) 및 포스트(1)에 형성되어 있는 볼트 구멍에 끼워 이들을 일체화 하는 체결볼트(3)와, 상기 체결볼트(3)의 나사부 끝단 쪽에 나사식으로 체결되거나 또는 용접으로 고정되어 상기 체결볼트(3)가 포스트(1)에서 분리되지 않도록 하는 고정너트(6)로 구성되는 가드레일의 설치방법에 있어서, 상기 펜스(2)와 포스트(1) 사이에 충격흡수구(9)를 위치시킨 후 상기 충격흡수구(9)의 중앙쪽 장공(9a)과 상기 포스트(1)에 형성된 볼트구멍(1a) 및 펜스(2)에 형성된 볼트구멍(2a)을 체결볼트(3)로 관통 결합시키고, 이 체결볼트(3)의 나사부에 스프링(4)을 외삽함과 동시에 상기 충격흡수구(9)의 좌우 측편(9b)에 형성되어 있는 보조 볼트구멍(9c)과 펜스(2)의 볼트구멍(2a)을 지지볼트(8)로 관통시키며, 상기 각 볼트(3)(8)들의 나사부 끝에는 너트를 채워서 분리되지 않도록 구성한다.As can be seen from the above drawings, in the present invention, a conventional fence (2) made by bending a steel plate of a predetermined thickness, a conventional post (1) in which the fence is fixed to an upper end portion, and these fences ( 2) and a fastening bolt 3 which is inserted into a bolt hole formed in the post 1 to integrate them, and is fastened by screwing or fixed by welding to the threaded end of the fastening bolt 3, the fastening bolt 3 In the installation method of the guard rail consisting of a fixing nut (6) to prevent the separation from the post (1), the shock absorbing opening (9) is located between the fence (2) and the post (1) The fastening bolt 3 penetrates the central hole 9a of the absorption port 9, the bolt hole 1a formed in the post 1, and the bolt hole 2a formed in the fence 2 through the fastening bolts 3, Extrapolating the spring (4) to the screw portion of the (3) and at the same time left and right of the shock absorbing opening (9) The auxiliary bolt hole 9c formed in the piece 9b and the bolt hole 2a of the fence 2 are penetrated through the support bolt 8, and the nut end is filled with the nut end of each of the bolts 3 and 8. Configure it so that it is not separated.
한편, 상기의 충격흡수구(9)로는 단면이형상이고, 그의 중앙과 좌우 측편(9b)에 각각 볼트를 체결할 수 있는 구멍(9a)(9c)이 형성되어 있는 것을 사용하며, 재료로는 금속재료를 사용한다.On the other hand, the cross section of the shock absorption port (9) is It has a shape, and holes 9a and 9c for fastening bolts are formed in the center and the left and right side pieces 9b, respectively, and a metal material is used as the material.
또한, 상기 펜스(2)의 전면쪽에는 길고 폭이 좁은 요홈을 형성하여, 이 부분에 반사 테이프(7)를 부착함으로서 가드레일의 기능을 더욱 향상할 수 있다.In addition, by forming a long narrow groove in the front side of the fence (2), by attaching a reflective tape (7) to this portion, it is possible to further improve the function of the guard rail.
첨부된 도면중 도 3은, 상기와 같은 구성을 갖는 본 발명의 가드레일에 차량이 충돌했을 때의 차량 거동을 시간의 흐름에 따라서 단계적으로 도시한 동작 예측도이다.3 is an operation prediction diagram showing the vehicle behavior when the vehicle collides with the guardrail of the present invention having the above configuration step by step over time.
이 도면에서 보는 바와 같이, 차량(V)이 가드레일(G)에 충돌되었을 때에는, 차량 엔진의 직진력과 가드레일로부터의 반발력이 복합적으로 차량에 작용되어, 차량이 좌우로 흔들리면서 불규칙으로 가드레일의 펜스(2)와 수회에 걸쳐 부딪치게 된다. 이 때, 펜스(2)로부터 주어지는 반발력이 크면 클수록, 차량이 전복될 우려가 높기 때문에, 반발력의 크기를 줄여야만 본 발명의 목적을 달성할 수 있다.As shown in this figure, when the vehicle V collides with the guard rail G, the linear force of the vehicle engine and the repulsion force from the guard rail are acted on the vehicle in combination, and the vehicle swings from side to side and irregularly guardrail. It hits the fence 2 of several times. At this time, the greater the repulsion force given from the fence 2, the higher the risk of the vehicle overturning. Therefore, the object of the present invention can be achieved only by reducing the size of the repulsive force.
상기 반발력은 펜스나 포스트가 찌그러지거나 부서질 때, 그의 변형에너지로 소모되므로써 그의 절대적인 힘은 줄어들 수 있지만, 펜스와 포스트가 완전히 부서지면, 차량이 낭떠러지와 같은 곳으로 추락하거나 중앙선 등을 넘어서 또다른 사고를 유발할 수도 있기 때문에, 펜스나 포스트가 완전히 부서지지 않는 한도 내에서 변형에너지로 발산되도록 유도해야 한다.When the fence or post is crushed or broken, its absolute power may be reduced by being consumed by his strain energy, but when the fence and post are completely broken, the vehicle may fall into a cliff or fall over the centerline or another accident. Because it can cause, it should be induced to dissipate as strain energy as long as the fence or post is not completely broken.
이에 본 발명에서는 가드레일에 가해지는 충격력이 포스트(1) 가까이에 작용할 경우에는 스프링(4)의 전체 길이가 줄어들게 하는 압축력으로 소모되게 하고, 펜스(2)쪽에 작용할 경우에는 펜스가 찌그러지면서 일차적으로 반발력을 소진하고, 펜스가 부서질 있는 더 큰 힘이 작용할 때에는 충격흡수구(9)의 좌우 측편이 휘어지도록 하여 반발력의 크기가 급격히 줄어들도록 만든다.Accordingly, in the present invention, when the impact force applied to the guard rail is acting close to the post (1), the total length of the spring (4) is to be consumed by the compressive force, and when acting on the fence (2) side the fence is crushed primarily When the repulsive force is exhausted, and the greater force that breaks the fence is applied, the left and right sides of the shock absorber 9 are bent, so that the magnitude of the repulsive force is sharply reduced.
이상과 같이, 본 발명의 방법에 따라 가드레일을 설치하면, 가드레일에 차량이 충돌되었을 때, 비록 차량 엔진의 직진력과 반발력이 서로 다른 방향으로 작용하고 있더라도, 펜스(2)를 따라서 차량이 스무스하게 이동되므로 차량이 낭떠러지로 추락하거나 다른 차선으로 되튕겨져 올라가는 일은 없어지게 된다. 따라서, 반발력에 의해 차량이 좌우로 흔들리다가 전복된다든지 또는 다른 차선으로 되튕겨져 올라가서 후속차량과 충돌되는 일이 없어지게 되어, 도로 주행시의 안전성을 더욱 향상시킬 수 있다.As described above, when the guardrail is provided in accordance with the method of the present invention, when the vehicle collides with the guardrail, the vehicle is moved along the fence 2 even though the straight and repulsive forces of the vehicle engine are acting in different directions. The smooth movement eliminates the need for vehicles to fall off the cliff or bounce up into other lanes. Therefore, the vehicle is not shaken from side to side by the repulsive force, and the vehicle is overturned or bounced back to other lanes and not collided with a subsequent vehicle, thereby further improving the safety during road driving.
