본 고안은 도로변에 설치되는 가드레일 단부의 안전구조에 관한 것으로 보다 상세하게는 가드레일 단부와 차량이 충돌시 단부가 차량내부로 파고 들어오는 것을 방지하면서 충격을 완화할 수 있게 하는 완충재의 부착구조에 관한 것이다.The present invention relates to a safety structure of the guard rail end installed on the roadside, and more particularly, to the attachment structure of the cushioning material that can alleviate the impact while preventing the guardrail end from digging into the vehicle when the vehicle collides with the guardrail end. It is about.

도로의 측면이나 중앙에 설치되는 가드레일은 차량이 주행선을 이탈하는 것을 방지하여 2차 사고를 방지하기 위한 것이나 가드레일 단부에 차량이 충돌할 경우 가드레일의 단부가 차량의 내부로 파고 들어와 치명적인 인명사고를 일으키거나 차량이 심하게 손상되는 경우가 있었다.Guardrails installed on the side or center of the road are designed to prevent the vehicle from leaving the line and prevent secondary accidents.However, if the vehicle collides with the guardrail end, the guardrail's end will dig into the interior of the vehicle There were accidents or serious damage to the vehicle.

종래 가드레일의 단부와 차량의 충돌시 차량을 보호하기 위하여 가드레일의 단부를 일체로 라운드지게 하거나 가드레일의 단부에 단조나 압연방식으로 제작된 굴곡부를 부착하는 방법과 가드레일의 단부에 고무나 합성수지재질을 일체로 사출하여 성형되는 완충재로 운전자의 시인성을 향상하고 충격을 완화할 수 있도록 하는 구성이 공지된바 있었다.In order to protect the vehicle in the event of a collision between the end of the guardrail and the vehicle, the end of the guardrail is integrally rounded, or a method of attaching a bent part manufactured by forging or rolling to the end of the guardrail and rubber or As a buffer material molded by injecting a synthetic resin material, there has been known a configuration for improving driver visibility and mitigating impact.

그러나 상기와 같은 가드레일 단부와 고무나 합성수지재를 일체로 사출성형하는 것은 가드레일을 성형하고 융용아연도금을 한 다음 금형을 이용하여 사출성형 하여야 하므로 금형제작비용이 과다하게 소요되고 사출성형시에도 많은 불량이 발생하는 등 작업에 어려움이 있었다.However, injection molding the guardrail end and the rubber or synthetic resin material integrally as described above requires molding the guardrail, hot dip galvanizing and then injection molding using a mold. Difficulty in work, such as a lot of defects occur.

본 고안은 상기와 같은 제반문제점을 해결하기 위하여 개발된 것으로 완충재가 구비된 가드레일의 단부를 형성하되 완충재만을 별도로 사출성형하여 체결구로 부착할 수 있게 하는 구성을 제공하는 것을 목적으로 한다.The present invention was developed in order to solve the above problems, and an object of the present invention is to form an end portion of the guard rail provided with a cushioning material, but to provide a configuration that can be attached to the fastener by injection molding only the cushioning material separately.

본 고안의 또 다른 목적은 가드레일 단부에 열가소성수지를 덧씌우고 열융착하여 완충재를 형성할 수 있게 하는 것이다.Still another object of the present invention is to cover a thermoplastic resin on the guard rail end and to heat-seal and form a cushioning material.

본 고안의 또 다른 목적은 완충재의 표면에 운전자의 시인성을 향상할 수 있는 안전표식을 부착하는 것이다.Another object of the present invention is to attach a safety mark to the surface of the cushioning material to improve the driver's visibility.

상기한 목적을 달성하기 위한 본 고안 '가드레일 단부의 부착식 완충구조'는 가드레일 단부에 고무나 합성수지와 같은 충격흡수효과가 있는 완충재를 덧씌우되, 완충재와 너트를 일체로 사출성형하고 완충재의 이면에는 다수의 슬릿형상의 공극을 형성하여 가드레일 표면에 부착되는 완충재가 충격에 의하여 보다 용이하게 변형될 수 있게 하면서 굴곡진 가드레일의 표면과 완충재의 이면형상이 다소 불일치하더라도 변형되어 쉽게 접촉될 수 있도록 하고 완충재의 가장자리에는 가드레일에 천공된 결합공을 통하여 볼트를 삽입하여 완충재와 일체로 성형된 너트와 볼트체결 하는 구성을 제공한다.The present invention 'adhesive cushioning structure of the guard rail end' to achieve the above object is to cover the guard rail end with a shock-absorbing effect, such as rubber or synthetic resin, injection molding the cushioning material and the nut integrally and On the back side, a plurality of slit-shaped pores are formed so that the cushioning material attached to the guardrail surface can be more easily deformed by impact, and the curved guardrail surface is deformed and easily contacted even if the backside shape of the cushioning material is somewhat inconsistent. And inserting the bolt through the coupling hole drilled in the guard rail at the edge of the cushioning material to provide a configuration for bolting with the nut integrally formed with the cushioning material.

또한 본 고안은 가드레일에 완충재를 부착함에 있어서 열가소성수지로 단부를 덧씌우고 열융착방식으로 접착되게 할 수도 있다.In addition, the present invention may cover the end with a thermoplastic resin in the attachment of the cushioning material to the guard rail and may be bonded in a thermal fusion method.

또한 본 고안은 완충재의 표면에 검은색 바탕면에 사선으로 표기되는 노란색안전표식으로 야광테이프를 부착하여 야간에도 운전자에게 보다 나은 시인성을 제공하게 할 수 있다.In addition, the present invention can be attached to the luminous tape with a yellow safety mark on the black surface of the buffer on the surface of the cushioning material to provide better visibility to the driver at night.

이하에서 본 고안의 바람직한 실시예를 첨부한 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2는 본 고안 가드레일 단부의 부착식 완충구조 단면도이며, 도 3은 본 고안 가드레일 단부의 부착식 완충구조 정면도이고, 도 4는 본 고안의 평면도이며, 도 5는 가드레일의 측단면도이다.FIG. 2 is a cross-sectional view of an attachable buffer structure of the guardrail end of the present invention, FIG. 3 is a front view of the attachable buffer structure of the guardrail end of the present invention, FIG. 4 is a plan view of the present invention, and FIG. 5 is a side cross-sectional view of the guardrail. .

도면에 도시된 바와 같이 본 고안 가드레일 단부의 부착식 완충구조는 가드레일(10)의 단부(11)를 인도측으로 다소 경사지게 굴곡하고 도로측을 향하는 표면에는 완충재(12)를 부착한다.As shown in the figure, the attached shock absorbing structure at the end of the guardrail 10 of the present invention bends the end 11 of the guard rail 10 slightly inclined toward the delivery side and attaches the cushioning material 12 to the surface facing the road side.

완충재(12)는 경질의 고무나 탄성이 있는 합성수지재로 성형되며 충격을 흡수하면서 쉽게 파손되지 않는 재질이 바람직하다.The cushioning material 12 is formed of hard rubber or elastic synthetic resin material, and preferably a material that is not easily broken while absorbing shock.

완충재(12)의 표면은 평탄하게 하여 표면에 안전표식이 부착될 수 있게 한다. The surface of the cushioning material 12 is leveled so that a safety mark can be attached to the surface.

완충재(12)의 이면은 가드레일(10)의 단부(11)굴곡면과 밀착될 수 있도록 동일한 굴곡부를 갖추며 가로 및 세로방향으로 깊은 슬릿형상의 홈(13)을 형성하여 완충재(12)에 가해지는 충격을 흡수시 굴곡부의 변형을 용이하게 하며 완충재(12)의 이면과 가드레일 굴곡부의 표면이 다소 일치하지 않더라도 접촉부가 쉽게 변형되어 밀착을 용이하게 하는 역할을 할 수 있게 한다.The rear surface of the buffer member 12 has the same bent portion to be in close contact with the curved surface of the end 11 of the guard rail 10, and forms a slit-shaped groove 13 deep in the horizontal and vertical directions and applied to the buffer member 12. When the shock is absorbed, it facilitates the deformation of the bent portion, and even if the back surface of the cushioning material 12 and the surface of the guardrail bent portion are somewhat inconsistent, the contact portion is easily deformed to serve to facilitate close contact.

완충재(12)는 사출성형시 가장자리부의 일정위치에 너트(14)를 삽입하여 일체로 성형되게 하며 너트(14)는 가드레일(10)에 천공된 체결공(15)을 통하여 삽입되는 볼트(16)에 의하여 가드레일(10)에 견고하게 고정될 수 있게 한다.The cushioning material 12 is integrally molded by inserting the nut 14 at a predetermined position of the edge portion during injection molding, and the nut 14 is bolt 16 inserted through the fastening hole 15 drilled in the guard rail 10. ) To be firmly fixed to the guard rail 10.

또한 본 고안에서 완충재(12)와 가드레일 단부(11)를 더욱 밀착되게 하기 위하여 가드레일 단부(11)에 열가소성수지로 된 커버를 덧씌우고 열융착방식으로 고정하게 할 수도 있다.In addition, in the present invention, in order to make the cushioning material 12 and the guard rail end 11 come into close contact with each other, the guard rail end 11 may be covered with a thermoplastic resin cover and fixed by heat fusion.

본 고안의 완충재(12)표면에는 운전자의 시인성을 향상할 수 있도록 안전표식(18)이 부착되며 안전표식(18)은 검은색 바탕면에 사선으로 표기된 노란색의 야광테이프(17)를 부착하여 야간에도 쉽게 식별할 수 있게 한다.The safety mark 18 is attached to the surface of the cushioning material 12 of the present invention to improve the driver's visibility, and the safety mark 18 is attached to the black background by attaching a yellow luminous tape 17 indicated by an oblique line at night. Even easy to identify.

이상에서 설명한 바와 같이 본 고안은 가드레일 단부에 완충재를 형성함에 있어서 완충재를 용이하게 부착할 수 있게 하고 차량과의 충돌시에도 충격흡수효과를 증대시켜 차량의 손상을 감소시키며 부착된 완충재의 표면에는 노란색 야광테이프로 형성되는 안전표식을 부착하여 야간에 운전자의 시인성을 향상할 수 있게 하는 효과가 있다.As described above, the present invention makes it possible to easily attach the buffer material at the end of the guard rail, increase the shock absorbing effect even when the vehicle collides with the vehicle, and reduce damage to the vehicle. The safety sign formed by the yellow luminous tape has an effect of improving the visibility of the driver at night.
