Description

내구성이 향상된 접지봉{GROUNDING ROD}Durable ground rod {GROUNDING ROD}

본 고안은 접지봉에 관한 것이며, 더욱 상세하게는 지중에 설치시 가해지는 강한 충격하중 및 반복하중에 의해 발생되는 휨 현상과 접지봉의 취부에 발생되는 파열 및 균열이 감소되어 내구성과 안정성이 향상된 접지봉에 관한 것이다.The present invention relates to a grounding rod, and more particularly, to a grounding rod having improved durability and stability due to the reduction of warpage and cracking caused by the strong impact load and the repeated load applied to the ground and the installation of the grounding rod. It is about.

기존에 활용된 접지봉은, 도 1에서 보는 바와 같이 인발가공에 의해 제작된 동관(12)의 상단을 확장하여 소켓(20)을 형성한 매설봉부(10)와; 상기 매설봉부에 형성된 소켓(20)에 삽설되며, 접지선(33)과 상기 매설봉부(10)를 연설하는 접지단자부(30)로 구성된다. 상기 동관(12)의 내부에는 철재 심봉(11)이 삽입된다.Existing ground rods, buried rod portion 10 to form a socket 20 by extending the upper end of the copper tube 12 produced by drawing as shown in Figure 1; It is inserted into the socket 20 formed in the buried rod portion, and consists of a grounding wire 33 and a ground terminal portion 30 extending the buried rod portion 10. The iron core 11 is inserted into the copper tube 12.

그러나 이와 같이 구성된 접지봉에 헤머 등을 이용하여 강한 외력을 가하여 지중에 삽설하게 되면 하기와 같은 문제점이 발생된다.However, when the ground rod is constructed in such a manner that a strong external force is applied using a hammer or the like, the following problems occur.

먼저 상기 접지봉은 외주면이 밋밋한 민무늬형태인데, 여기에 헤머 등으로 강한 외력을 가하여 지중에 삽설하면, 접지봉 자체에 휨현상이 발생되므로 사실상 손쉽게 지지봉을 지중에 삽설하기는 어렵다.First, the ground rod is a flat pattern with a flat outer circumference, and when it is inserted into the ground by applying a strong external force with a hammer, etc., it is difficult to easily insert the support rod into the ground because bending occurs in the ground rod itself.

또한 상기 삽입되는 접지단자의 선단부가 위치하는 소켓의 선단 결합부위 및 접지단자부와 접지선과의 결속부위에는 과다한 반복하중 및 충격하중이 가해져 이들 부위에는 파열 및/또는 크랙이 발생하게 되며, 이렇게 발생된 파열 및/또는 크랙부위에는 물이 스며들어가 부식 내지 산화가 빨리 진행되는 문제가 발생됨은 물론, 접지봉의 접지저항이 현저히 저하되는 문제점 또한 발생하게 된다.In addition, an excessive repetitive load and an impact load are applied to the tip coupling portion of the socket in which the tip portion of the ground terminal is inserted and the coupling portion of the ground terminal portion and the ground wire are ruptured and / or cracked at these portions. In addition to the problem of rupture and / or cracks in the water to rust corrosion or oxidation proceeds quickly, the ground resistance of the ground rod is also significantly reduced.

특히 접지봉은, 지중에 매설되어 있는 관계로 접지사고 등이 발생하여 지하에 묻힌 접지봉들을 파헤쳐 보기 전까지는 상기와 같은 문제점을 제대로 파악할 수 없기 때문에 문제의 심각성을 실제로 매우 중대하다고 할 수 있다.Particularly, since the ground rod is buried in the ground, the seriousness of the problem can be said to be very serious because the above problem cannot be properly understood until a ground accident or the like is dug up to dig the ground rod buried underground.

본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로, 본 고안의 목적은 지중에의 삽설시, 해머 등에 의해 가해지는 강한 충격하중 및 반복하중에 의해 발생되는 휨 현상과 접지봉의 취부에 발생되는 파열 및 균열현상이 억제되어 내구성과 사용상의 안전성이 향상된 접지봉을 제공함에 있다.The present invention was devised to solve the above problems, and the object of the present invention is the bending caused by the strong impact load and the repeated load applied by the hammer or the like during insertion into the ground and the rupture caused by the installation of the ground rod. And the crack phenomenon is suppressed to provide an earthing rod with improved durability and safety in use.

이때 접지단자부(30)의 외경은, 상기 접지단자부(30)가 삽설되는 소켓부의 삽입공(21) 내경보다 약간 크도록 제작하는 것이 바람직한데, 이는 소켓부(20)의 삽입공(21)에 접지단자부(30)가 억지끼움되도록 하기 위함이다.At this time, the outer diameter of the ground terminal portion 30, it is preferable to make the ground terminal portion 30 is slightly larger than the inner diameter of the insertion hole 21 of the socket portion is inserted, which is inserted into the insertion hole 21 of the socket portion 20 This is to prevent the ground terminal portion 30 is fitted.

본 고안에서는 이와 같이 구성된 매설봉부(10)와 소켓부(20)의 중첩부위에 외부에서 제공되는 가압력을 제공하여 압착부(22)를 형성함으로써, 매설봉부(10)와 소켓부(20)가 상호 긴밀히 결합되도록 하고 있다.In the present invention, by providing a pressing portion 22 to the overlapping portion of the buried rod portion 10 and the socket portion 20 configured as described above to form a crimping portion 22, the buried rod portion 10 and the socket portion 20 ) Are tightly coupled to each other.

또한 상기 매설봉부(10)와 접지단자부(30)의 외주면 및 소켓부(20)의 내주면에는, 도 5에서 보는 바와 같이 일정한 간격으로 배열된 다수의 종방향의 직선상 요철(13, 23, 31)을 각각 형성하여, 접지봉(1)을 지중에 삽설시 해머 등에 의해 가해지는 외력에 의해 접지봉(1)의 휘는 현상을 방지함과, 동시에 삽설이 보다 용이하게 이루어지도록 하고 있다.Further, on the outer circumferential surface of the buried rod portion 10 and the ground terminal portion 30 and the inner circumferential surface of the socket portion 20, as shown in FIG. 5, a plurality of longitudinal straight irregularities 13, 23, arranged at regular intervals, 31) are formed to prevent the ground rod 1 from bending due to external force applied by a hammer or the like when the ground rod 1 is inserted into the ground, and at the same time, the insertion can be performed more easily.

도 6의 (a)와 (b)는 본 실시예에 따른 접지봉의 설치상태를 보여주는 것으로, 이들 도면을 참조하여 접지봉의 설치과정을 설명하기로 한다.6 (a) and 6 (b) show the installation of the ground rod according to the present embodiment, with reference to these drawings will be described the installation process of the ground rod.

작업자가 매설봉부(10)의 상부에 형성된 소켓부(20)의 삽입공(21)에, 삽입공(21)의 내경보다 작은 가압봉(P)을 삽입하여 해머(H) 등으로 상기 가압봉(P)을 치게 되면, 매설봉부(10) 및 소켓부(20)는 지중에 매설된다.A worker inserts a pressure rod P smaller than the inner diameter of the insertion hole 21 into the insertion hole 21 of the socket portion 20 formed at the upper portion of the embedding rod portion 10 and presses the pressure with a hammer H or the like. When the rod P is hit, the embedding rod portion 10 and the socket portion 20 are embedded in the ground.

이때, 상기 소켓부(20)와 매설봉부(10)가 중첩되는 부위에 형성된 압착부(22)는, 가압봉(P)을 통해 제공된 외력이 매설봉부(10) 전체에 걸쳐 골고루분산되도록 하여, 소켓부(20)가 파열되는 것이 방지하게 되고, 또 매설봉부(10)와 소켓부(20)는, 외주면 또는 내주면에 형성된 다수의 종방향의 직선상 요철(13, 23)에 의해 강성이 보완되어, 휨 현상이 방지된다.At this time, the crimping portion 22 formed at the overlapping portion of the socket portion 20 and the buried rod portion 10, so that the external force provided through the pressure rod (P) is evenly distributed throughout the buried rod portion (10). This prevents the socket portion 20 from rupturing, and the embedding rod portion 10 and the socket portion 20 are formed by a plurality of longitudinal straight unevennesses 13 and 23 formed on the outer circumferential surface or the inner circumferential surface thereof. Rigidity is compensated for, and warpage is prevented.

이후 작업자가 가압봉(P)을 소켓부(20)에서 제거한 후, 접지선(33)이 결속된 접지단자부(30)를 소켓부(20)의 삽입공(21)에 삽입하게 되는데, 이때 상기 접지단자부(30)의 직경은 소켓부(20)의 삽입공(21) 내경보다 외경이 약간 큰 관계로, 작업자가 접지단자부(30)를 해머 등으로 치게 되면, 접지단자부(30)는 소켓부(20)의 삽입공(21)에 억지끼움 되어 안정된 결속상태를 유지하게 된다.Thereafter, after the worker removes the pressure bar P from the socket 20, the ground terminal 33 to which the ground wire 33 is bound is inserted into the insertion hole 21 of the socket 20, wherein the ground Since the diameter of the terminal part 30 is slightly larger than the inner diameter of the insertion hole 21 of the socket part 20, when the worker hits the ground terminal part 30 with a hammer or the like, the ground terminal part 30 is connected to the socket part ( It is inserted into the insertion hole 21 of 20) to maintain a stable binding state.

또한 상기 소켓부(20) 삽입공(21) 내주면과 접지단자부(30)의 외주면에 형성된 다수의 종방향의 직선상 요철들(23, 31)은, 이들의 결합력을 보다 향상시킴과 동시에 강성을 보완하여 접지단자부(30)와 소켓부(20)가 휘는 것을 방지하게 된다.In addition, the plurality of longitudinal straight irregularities 23 and 31 formed on the inner circumferential surface of the socket portion 20 insertion hole 21 and the outer circumferential surface of the ground terminal portion 30 further improve their coupling force and at the same time increase rigidity. In addition, the grounding terminal 30 and the socket 20 are prevented from bending.

상술한 바와 같이, 본 고안에 따른 접지봉은 지중의 삽설시, 해머 등에 의해 가해지는 강한 충격하중 및 반복하중에 의해 발생되는 휨 현상과 접지봉의 취부에 발생되는 파열 및 균열현상이 억제되어 내구성과 사용상의 안전성이 향상되는 효과가 있다.As described above, the grounding rod according to the present invention is suppressed from the bending caused by the strong impact load and the repeated load applied by the hammer or the like during the insertion of the ground, and the rupture and cracking caused by the mounting of the grounding rod are suppressed.
