본 발명은 연결식 접지봉에 있어서 연결부를 보강한 접지봉의 제조방법에 관한 것이다. 종래에는 접지봉을 연결하여 함마로서 땅에 타입하면 피복된 동의 "인발"이 멈춘 절곡 또는 파열되는 결점이 있었다.The present invention relates to a method for manufacturing a grounding rod reinforcing a connecting portion in a grounding ground rod. Conventionally, when the ground rod is connected to the ground as a hammer, the coated copper "pull" has a defect of bending or breaking.

본 발명은 이와같은 점을 감안하여 접지봉의 세봉상이나 경사진 연결부는 동피복 두께가 더 두껍게 형성되게 하여 기계적 강도가 높도록 보강한 것이다.In view of the above, the present invention is to reinforce such that the three rod-like or inclined connection portion of the ground rod is formed to have a thicker copper coating thickness, so that the mechanical strength is high.

본 발명의 제조방법을 설명하면 다음과 같다.Referring to the manufacturing method of the present invention.

제1도와 같이 표면이 "너어링"된 강철봉(1)의 일단은 침(2)으로 형성하고 타단의 일부에는 강철봉(1) 외경보다 약간 가늘게된 세봉(3)의 끝단부에는 동 단관을 압착하여 외경을 크게한 끝단부(4)를 일체로 형성하여 강철봉(1)에 "너어링"된 표면에는 도전성 콤파운드를 도포하여 강철봉의 끝단부(4)의 외경에 꼭 맞는 동파이프(5)에 강철봉(1)을 끼운 다음 제2도와 같이 통상의 "인발"공정으로 침(2)에서부터 세봉(3)의 끝단부(4)까지 "인발"하면 경사부(7)와 내부 공간(8)을 이루면서 끝단부(4)외경에 꼭 끼워진 연결관(6)이 직선상으로 형성되는 것이다. 이와같이 연결관(6)과 경사부(7) 세봉(3)상에는 두껍게 피복되어 연결부를 보강하였고 강철봉(1)에는 얇게 피복된 것이며, 연결관(6)은 세봉(3) 끝단부(4)의 동단관과 결합되어 지지되고 있으므로 연결관(6)에 도시되지 않은 통상의 리드봉을 꽂고 함마로 쳐서 타입해도 경사부(7)는 파손되지 않게되는 것이다.As shown in FIG. 1, one end of the steel rod 1 having the surface "nering" is formed with a needle 2, and a portion of the other end is crimped at the end of the three rod 3 slightly thinner than the outer diameter of the steel bar 1. To the copper pipe 5, which is formed so that the outer end portion 4 having a larger outer diameter is integrally formed, and a conductive compound is applied to the surface that is "nered" on the steel bar 1 to fit the outer diameter of the end portion 4 of the steel bar. Insert the steel bar 1 and then "draw" from the needle 2 to the tip 4 of the three rods 3 in the usual "draw" process as shown in FIG. 2 to form the inclined portion 7 and the internal space 8. While forming a connection pipe 6 is fitted in a straight line to the outer end portion (4). In this way, the connecting pipe 6 and the inclined portion 7 are thickly coated on the three rods 3 to reinforce the connecting portion, and the steel rods 1 are thinly coated, and the connecting tube 6 is formed of the ends of the three rods 4. Since it is supported by being coupled with the same end pipe, the inclined portion 7 will not be damaged even if a normal lead rod (not shown) is inserted into the connecting pipe 6 and hit with a hammer.

한편 "인발"공정으로 표면에서 밀리는 도전성 콤파운드는 "인발"이 멈춘 공간(8)에 밀봉된다. 이로 인하여 강철봉(1)과 동피복이 밀착된 부위로 물기가 유입되지 않게되므로 산화부식 방지도 되고 접촉 도전성도 높이도록 하였다. 이와같이 접지봉은 연결부에는 두께운 동피로 보강하였으므로 기계적인 강도가 높아 제3도와 같이 연결하여 땅에 타성하여도 연결부는 절곡, 파열되지 않는 효과가 있는 것이다.On the other hand, the conductive compound that is pushed off the surface by the "draw" process is sealed in the space 8 in which "draw" has stopped. This prevents water from entering the area where the steel bar 1 and the copper cladding are in close contact, thereby preventing oxidation corrosion and increasing contact conductivity. In this way, the ground rod is reinforced with a thick copper shell on the connection part, so the mechanical strength is high, so that the connection part is not bent or ruptured even if it is inerted on the ground.
