Abstract
Description
본 발명은 도로 가장자리에 설치되는 차량 추락방지용 가드레일의 원형 강관지주에 관한 것으로, 도로이탈 차량이 가드레일 판재에 충돌시 지주에 가해지는 수평력에 의하여 지주가 뒤로 밀려 전도되는 것을 억제하도록 지반의 수평 저항력을 높이기 위한 것이다.The present invention relates to a circular steel pipe holding of the guardrail for vehicle fall prevention installed on the edge of the road, the horizontal of the ground so as to suppress the propulsion is pushed backward by the horizontal force applied to the support when the road departure vehicle collides with the guardrail plate It is to increase the resistance.
지반의 수평저항력은 구조체로 사용되는 강관의 지름(=폭)과 길이가 그 주요인자이다. 그러나, 가드레일 지주는 일반적으로 ø139.8×4.5T규격이 표준화되어 사용하고 있으며 도로의 가장자리인 성토 비탈면 정상부에 도2와 같이 설치되고 있어 표준화된 원형 강관지주의 지름인 139.8mm로는 지반의 수평 저항력이 부족하다.The horizontal resistance of the ground is the diameter (= width) and length of the steel pipe used as the structure is the main factor. However, the guardrail prop is generally standardized in ø139.8 × 4.5 T standard and is installed at the top of the fill slope, which is the edge of the road, as shown in Fig. 2. Lack of resistance
따라서, 본 발명에서는 가드레일 지주의 폭을 증가시켜 지반의 수평저항력을 증가시킴으로서 도로이탈 차량의 충돌로 지주에 가해지는 수평력에 의하여 취약한 비탈 정상부에서 가드레일 지주가 뒤로 밀려 전도되는 것을 억제하고자 하는 것이다.Therefore, in the present invention, by increasing the width of the guard rail support to increase the horizontal resistance of the ground by the horizontal force applied to the support due to the collision of the off-road vehicle to prevent the guard rail support from being pushed back at the top of the weak slope. .
지주로 사용되는 강관의 경우 외경과 두께가 표준화되어 생산되기 때문에 종래에는 지반의 수평저항력이 부족할 경우, 흙 속에 설치되는 지주의 길이를 길게 하거나 외경이 큰 강관을 사용해 왔으나 가드레일 지주는 항타하여 매입, 시공하고 있는데 지주의 길이가 길 경우에는 항타 작업이 곤란하고, 관경이 클 경우에는 지하에 매설된 통신케이블 등의 저촉과 통행시 시야차단으로 인한 미관 및 경관장애 등을 감안할 때 표준 규격의 외경보다 큰 치수는 사용이 곤란하다.In the case of steel pipes used as props, since the outside diameter and thickness are standardized and produced, when the horizontal resistance of the ground is insufficient, the length of the posts installed in the soil has been lengthened or steel pipes with large outside diameters have been used. If the length of the post is long, it is difficult to operate the navigator. If the diameter is large, the outside diameter of the standard standard is considered in consideration of the interference of the communication cable buried in the basement and the aesthetics and landscape obstacles caused by the blockage of sight during traffic. Larger dimensions are difficult to use.
이와 같은 기존의 원형 강관지주의 문제점을 보완하기 위하여 본 발명은 기존 가드레일 원형 강관지주를 사용하여 지반의 수평저항력을 높여 보겠다는 것이다. 즉, 지주로 쓰이는 원형 강관지주 외부에 수평지반반력의 계산을 통하여 구해진 적절한 폭과 모양을 가진 철재 보강리브를 고정시킴으로서 수평지반반력을 증가시켜 종래에 사용되어 온 지주보다 같은 외경으로 지반의 수평저항력을 높이는데그 목적이 있다.The present invention is to improve the horizontal resistance of the ground by using the existing guardrail circular steel pipe column to supplement the problems of the existing circular steel pipe column. In other words, by fixing steel reinforcing ribs with the appropriate width and shape obtained through the calculation of the horizontal ground force on the outside of the circular steel pipe column, which is used as the support, the horizontal resistance of the ground is increased with the same outer diameter than the conventionally used shore. The purpose is to increase.

＜도면의 주요부분에 대한 부호의 설명＞<Description of the code | symbol about the principal part of drawing>
1 : 가드레일 지주 2 : 가드레일 판재1: Guardrail Shore 2: Guardrail Plate
3 : 보강리브3: Reinforcement Rib
이러한 목적을 달성하기 위하여 본 발명의 기술적 구상을 살펴보면, 가드레일 지주(1) 외부에 '-'자형 철재 보강리브(3)를 지주에 작용하는 힘의 직각방향으로 고정시키는 것을 특징으로 하고 있다.Looking at the technical concept of the present invention in order to achieve this object, it is characterized in that the '-' shaped steel reinforcing ribs (3) fixed to the right angle direction of the force acting on the posts outside the guardrail support (1).
본 발명의 실시 예를 첨부한 도면을 참고하여 설명하면 다음과 같다.An embodiment of the present invention will be described with reference to the accompanying drawings.
본 발명의 보강리브(3)가 지주(1)의 외부에 설치된 가드레일 원형 강관지주가 필요할 때 먼저 수평지반반력계산을 통하여 도 2와 같이 경사지반에 설치된 지주가 외력에 저항할 수 있는 지주의 폭과 길이를 구한 다음 설계에 맞게 보강리브(3)를 제작하여 강관 외부에 도 3과 같이 용접 등을 이용하여 고정하도록 한다.When the guardrail circular steel pipe column of the present invention is required to have a guard rail circular steel pipe column installed on the outside of the support 1, the support of the support can be resistant to external force as shown in FIG. After obtaining the width and length to make a reinforcement rib (3) according to the design to be fixed to the outside of the steel pipe using a welding or the like as shown in FIG.
상기와 같은 본 발명에 의하면 가드레일 지주로 쓰이는 원형강관의 외부에 철재 보강리브를 설치함으로써 지주가 차량충돌시 발생되는 수평력에 저항하는 지반의 수평저항력이 증가되어 기존의 원형 강관지주의 지반수평저항력의 부족으로 지주가 뒤로 밀려 전도되는 문제점이 해소된다. 따라서, 표준규격의 원형 강관으로 지주를 제작할 수 있고, 지반의 형상에 따라 필요시 보강리브의 폭의 조절과 지주의 길이를 조절할 수 있는 유용한 발명인 것이다.According to the present invention as described above by installing the steel reinforcement ribs on the outside of the circular steel pipe used as guard rail support, the horizontal resistance of the ground to resist the horizontal force generated when the land vehicle crashes, the ground horizontal resistance of the existing circular steel pipe support The problem that the landlord is pushed back due to lack of people is solved. Therefore, it is a useful invention that can be made of the support of the standard standard circular steel pipe, and can adjust the width of the reinforcing rib and the length of the support if necessary according to the shape of the ground.
