Description
볼트캡에 관한 것으로, 더욱 상세하게는 고속도로 또는 자동차전용도로, 일 반도로의 코너부 또는 도로와 교량 측면에 설치되는 교량난간 및 방음벽 지주를 고정하기 위한 고정볼트의 녹을 방지하기 위해 씌워지는 볼트캡에 형광물질을 도포하거나 반사판 등을 부착시켜 주행 중인 차량이 쉽게 육안으로 확인할 수 있도록 하여 도로의 안전사고를 감지할 수 있는 교량난간 및 방음벽 지주에 장착한 안전식별구조겸 녹막이방지용 볼트캡에 관한 것이다.It relates to a bolt cap, and more specifically to the highway or automobile road, work Applying fluorescent material or reflecting plate to bolt cap which is covered to prevent rust of fixing bolt for fixing bridge rail and soundproof wall strut installed on corner of peninsula or side of road and bridge Safety identification structure and rust prevention bolt cap mounted on bridge railings and soundproof wall props to detect road safety accidents.
일반적으로, 도로의 형태에 따라 다양한 구조를 갖추고 있고 새로운 구조물 설치공법의 출현으로 보다 견고한 상태를 유지할 수 있는 식별구조물들이 지속적으로 선 보이고 있으나, 예를들면, 자동차 전용 도로의 경계부에 방음벽지주들이 일정 길이로 설치되게 되는 데, 이는 지면으로부터 일정 높이로 설치되는 원형 또는 H형의 포스트에 볼트 및 너트 등에 의해 연속적으로 체결된다.In general, identification structures that have various structures according to the shape of the road and which can maintain a more solid state with the emergence of new structure installation methods are continuously shown. It is installed to a length, which is continuously fastened by bolts and nuts, etc. to a circular or H-shaped post installed at a certain height from the ground.
특히, 콘크리트 옹벽 위에 H형상 방음벽 지주 및 일정한 콘크리트 높이에 교량 난간이 너트와 볼트로 체결되어 있다.In particular, the bridge railings are fastened by nuts and bolts to the H-shaped soundproof wall support and the concrete concrete height on the concrete retaining wall.
이때, 볼트는 대기중에 노출되어 있기 때문에, 빗물 또는 매연 등에 의해 부식되어 차후 상기 교량난간 및 방음벽지주가 예기치 못한 사고 또는 노후화 되어 교체할 경우 많은 현장에서 너트 및 볼트가 분해되지 않아 산소로 절단하고 재시공이 불가능한 사례가 종종있었다.At this time, since the bolt is exposed to the atmosphere, it is corroded by rainwater or soot, so that the bridge rails and the soundproof wall column are cut and rebuilt with oxygen because many nuts and bolts do not decompose in many sites when the accident occurs due to an unexpected accident or aging. There were often cases of this impossible.
본 고안은 상기와 같은 문제점을 해소하기 위한 것으로, 교량난간이나 방음벽지주를 고정하기 위한 볼트의 외부에 덧씌움으로서, 볼트의 녹막이를 방지할 수 있도록 하는 데에 있다.The present invention is to solve the problems as described above, by covering the outside of the bolt for fixing the bridge railings or soundproof wall pillar, to prevent the rust of the bolt.
또 다른 목적은 상기 볼트의 외주면을 감싸도록 한 볼트캡의 제조시 형광물질 또는 반사물질을 혼합 도포하여 주행중의 차량이 쉽게 육안으로 파악할 수 있도록 함으로서, 안전사고를 미연에 방지하도록 하는 데에 있다.Still another object is to prevent the safety accident by applying a fluorescent material or a reflective material to the outside of the bolt cap to cover the outer circumferential surface of the bolt so that the vehicle can be easily seen by the naked eye.
상기와 같은 목적을 달성하기 위하여, 본 고안은 고속도로 또는 자동차 전용도로, 일반도로의 코너부에 설치되어 주행하는 차량을 보호하기 위한 교량난간 또는 방음벽지주를 고정하기 위한 볼트에 있어서, 상기 볼트의 외부에 녹막이 방지용 볼트캡이 덧씌워진 것을 특징으로 한다.In order to achieve the above object, the present invention is a bolt for fixing a bridge railing or a soundproof wall circumference for protecting a vehicle that is installed in a corner of a highway or an automobile-only road, a general road, the outside of the bolt It is characterized in that the anti-rust bolt cap is overlaid on.
또한, 상기 녹막이 방지용 볼트캡의 외주연에 야광물질 또는 발광물질 및 반사지가 도포됨을 특징으로 한다.In addition, a luminous material or a light emitting material and a reflecting paper are coated on the outer circumference of the rust preventing bolt cap.
또한 상기 녹막이 방지용 볼트캡의 내주면에 와셔 삽입부 및 너트 삽입부가 형성되며, 상기 너트 삽입부의 내측면에 너트에 기밀하게 고정하기 위한 체결수단이 형성됨을 특징으로 한다.In addition, a washer insert and a nut insertion part are formed on an inner circumferential surface of the rust preventive bolt cap, and a fastening means for hermetically fixing the nut is formed on an inner surface of the nut insertion part.

이하, 첨부도면에 의하여 본 고안의 바람직한 실시 예를 상세히 설명하면 다 음과 같다.Hereinafter, the preferred embodiment of the present invention by the accompanying drawings in detail as follows.
본 고안은 도 1에 나타낸 바와 같이, 고속도로 또는 자동차 전용도로, 일반도로의 코너부에 설치되어 주행하는 차량을 보호하기 위한 교량난간 또는 방음벽지주(1)을 고정하기 위한 볼트(10)의 외부에 녹막이 방지용 볼트캡(100)이 덧씌워짐에 그 기술적 구성상의 특징이 부여된다.As shown in FIG. 1, the present invention is installed on a corner of a highway or an automobile-only road, a general road, on the outside of a bolt 10 for fixing a bridge railing or a soundproof wall support 1 for protecting a vehicle. The technical protection feature is given to the rust protection bolt cap 100 is overlaid.
상기 녹막이 방지용 볼트캡(100)의 재질은 합성수지재 또는 고무, 금속재질 로 제조할 수 있으며, 바람직하게는 금속재를 사용할 경우에는 외부의 부식을 고려하여 그 재질을 선택하는 것이 좋으며, 도 2a에 도시된 바와 같이, 하부가 개구되며 볼트(10)를 체결하고 있는 와셔 및 너트(도시하지 않음)가 삽입되기 위한 와셔삽입부(110) 및 너트 삽입부(120)가 각각 형성된다.The material of the rust preventive bolt cap 100 is a synthetic resin material or rubber, metal material In the case of using a metal material, it is preferable to select the material in consideration of external corrosion. As shown in FIG. 2A, a washer having a lower opening and fastening the bolt 10 and Washer insert 110 and nut insert 120 for inserting a nut (not shown) are respectively formed.
또한, 상기 너트 삽입부(120)의 내측면에 너트의 외주면에 기밀하게 고정하기 위한 체결수단(200)이 형성된다.In addition, a fastening means 200 is formed on the inner surface of the nut insert 120 to hermetically fix the outer peripheral surface of the nut.
예를들면, 상기 체결수단(200)은 도 2a의 요부확대도 및 도 3에 도시된 바와 같이, 너트 삽입부(120)에 등간격으로 형성되는 관통 설치구멍(121)과, 이 설치구멍(121)에 삽입되는 스톱볼(122)과, 상기 스톱볼(122)을 탄성력있게 지지하기 위한 탄성수단(123)과, 상기 탄성력을 유지하며, 상기 스톱볼(122)이 설치구멍(120)으로부터 나오는 것을 방지하기 위해 상기 설치구멍(121)에 나사맞춤되는 마구리부(124)로 구성되며, 상기 녹막이방지용 볼트캡(100)이 볼트 및 너트 위에 덧 씌워질 경우 상기 볼트(10)로부터 1차적으로 이탈 되는 것을 방지하기 위해 다수개의 리브(125)가 설치된다.For example, the fastening means 200 is an enlarged view of the main portion of Fig. 2a and as shown in Fig. 3, the through-hole mounting holes 121 formed at equal intervals in the nut insertion portion 120 and the mounting hole ( A stop ball 122 inserted into 121, an elastic means 123 for elastically supporting the stop ball 122, and maintains the elastic force, the stop ball 122 from the installation hole 120 It is composed of a ridge portion 124 that is screwed into the installation hole 121 to prevent it from coming out, and when the rust preventive bolt cap 100 is overlaid on the bolt and nut, primarily from the bolt 10 A plurality of ribs 125 are installed to prevent them from being separated.
이때, 상기 리브(125)의 개수 및 넓이 폭은 볼트 및 너트의 크기에 따라 약간 차이를 두고 설정할 수가 있음과 아울러 볼트의 나사산에 끼워맞춤되도록 입구쪽이 넓고 폐단면쪽으로 향할수록 좁아지도록 경사지게 형성하는 것이 바람직하다.In this case, the number and width of the ribs 125 may be set to be slightly different depending on the size of the bolt and nut, and the inlet side is wider to be fitted to the thread of the bolt and inclined to become narrower toward the closed end surface. It is preferable.
따라서, 상기와 같이 구성되는 교량난간 또는 방음벽지주에 장착한 안전식별구조겸용 녹막이방지용 볼트캡(100)은 도 1에 도시된 바와같이, 볼트(10)의 외주면에 씌워짐으로서, 볼트가 빗물 또는 매연 등에 의해 부식되는 것을 방지할 수가 있 는 것이다.Accordingly, the bolt cap 100 for preventing rust prevention combined with the safety identification structure mounted on the bridge railing or the soundproof wall circumference configured as described above is covered with the outer circumferential surface of the bolt 10, as shown in FIG. Or corrosion by soot Will.
이때, 상기 녹막이방지용 볼트캡(100)에 형성된 체결수단(200)은 와셔와 너트 사이의 틈새에 체결되도록 함으로서, 상기 녹막이방지용 볼트캡(100)가 볼트(10)로부터 이탈되는 것을 2차적으로 방지할 수가 있는 것이다.At this time, the fastening means 200 formed on the rust prevention bolt cap 100 is fastened to a gap between the washer and the nut, thereby preventing the rust prevention bolt cap 100 from being separated from the bolt 10. This can be prevented.
또한, 상기 녹막이 방지용 볼트캡(100)은 상기 형상에 한정하는 것이 아니라 도 2b 또는 도 2c 등에 도시된 바와 같이 여러 형상으로 형성할 수가 있는 것이다.In addition, the rust preventive bolt cap 100 is not limited to the above shape can be formed in various shapes as shown in Figure 2b or 2c.
예를들면, 평면에서보아 대략 '◇','▽','□' 및 육각형상 등으로 사출할 수가 있는 것이다.For example, it can be ejected into approximately '◇', '▽', '□' and hexagonal shapes in plan view.
이상과 같이 본 고안은 교량난간 또는 방음벽지주를 고정하기 위한 볼트의 외주면에 덧 씌워짐으로서, 매연 및 빗물 등에 의해 부식되는 것을 미연에 방지할 수가 있으며, 이로 인한 보수가 용이하고, 또한, 필요에 따라 여러 색상으로 제작할 수 있어 외관이 미려하여 환경미화를 도모할 수가 있다.As described above, the present invention is overlaid on the outer circumferential surface of the bolt for fixing the bridge railing or the soundproof wall circumference, and can prevent corrosion in advance by soot and rainwater. Therefore, it can be produced in various colors, so that the appearance is beautiful and the environment can be promoted.
또한, 상기 녹막이 방지용 볼트캡의 외주연에 야광물질 또는 발광물질을 도포함으로서, 주행 중의 차량이 쉽게 이를 파악하여 안전사고를 미연에 방지할 수가 있는 이점이 있다.In addition, by including a luminous material or a light emitting material on the outer circumference of the rust prevention bolt cap, there is an advantage that the vehicle while driving can easily grasp this and prevent safety accidents.
