Description

Underground track indicator {LINE MARK}

일반적으로 도로의 지하에 매설된 각종선로,배관을 지상에서 알 수 있도록 매설공사가 완료되면 지면에 표시못을 설치한다. 그 설치방법을 보면 도 2에서 보는 바와 같이 매설방향을 표시하기 위하여 드릴로 구멍을 뚫어 표시못을 설치하고 몰타르,시멘트 등 고정재를 넣고 고정시킨다.In general, when the construction is completed so that the various tracks and pipes buried in the basement of the road can be seen from the ground, marking pegs are installed on the ground. In the installation method, as shown in Fig. 2, a drill is installed in order to display the buried direction, and a display nail is installed, and a fixing material such as mortar and cement is inserted and fixed.

도 2는 종래의 표시못을 설치한 도면으로 배관,지중선을 표시하는 머리부(34)와 본체(31)을 고정하는 고정부(32)가 머리부(34)를 형성한 표시못으로 이루어져 있다. 본체(31)의 저면에 가로,세로돌기(36)등을 형성한 고정부(32)에 드릴로 구멍을 뚫어 설치하므로 타이어의 충격등에 표시못의 변형으로 안전을 기할 수 없는 단점이 있었다.FIG. 2 is a view in which a conventional display nail is installed, and includes a display nail in which a head part 34 fixing a pipe and an underground line and a fixing part 32 fixing the main body 31 form a head part 34. . Since a hole is drilled and installed in the fixing part 32 having the horizontal and vertical protrusions 36 formed on the bottom of the main body 31, there is a disadvantage in that safety cannot be provided due to deformation of the display nail in the impact of the tire.

본 고안은 도 1에서와 같이 본체(1)와 본체고정부(2)를 고정볼트(3)와 쐐기형넛트(4)로 꽉조여서 체결하고 본체(1)에 방향표시부(8)를 결합하여 설치하므로 차량의 타이어에 의한 충격등이 있더라도 본체고정부(2)의 하단이 절개홈(7)으로 파쇠되어있고 그 구멍내부에 4개의 돌출턱이 형성된 쐐기형넛트(4)가 고정볼트(3)로 꽉 조여 체결되기 때문에 절개홈이 벌어져 도로면에 드릴로 뚫은 구멍에 체결되어 본체(1)가 회전하지 않도록 하였다.The present invention is fastened by fastening the main body 1 and the main body fixing part 2 with the fixing bolt 3 and the wedge-shaped nut 4 as shown in Figure 1 by combining the direction display portion 8 to the main body 1 Therefore, even if there is an impact caused by the tire of the vehicle, the wedge-shaped nut 4 having the lower end of the main body fixing part 2 is broken into the incision groove 7 and the four protruding jaws formed in the hole is fixed bolt (3). Because it is tightened tightly with), the incision groove is opened and fastened to a hole drilled in the road surface so that the main body 1 does not rotate.
