본 발명은 전주를 세워 매립설치하는 건주 공사시에 전주의 견고한 근착을 위해 전주의 하단부에 오거크레인용 확장기를 이용하여 매립되는 접지기능 아치형 전주근가에 관한 것으로, 특히 콘크리트에 의해 양생된 아치형 전주근가와 그 전주근가의 평면 형상과 대응하여 저면에 밀착 형성되는 금속재로 된 접지판의 사이에 도전성 콘크리트층을 형성하여, 전주근가와 접지판의 견고한 결합은 물론 접지판의 전식 및 부식을 방지하여 접지 저항성이 안정적으로 유지되게 한 것이다.The present invention relates to a grounding function arch type electric pole root which is buried using an auger crane expander at the lower end of the pole for the strong mounting of electric pole at the construction of the construction of the land rebuilding installation of the pole. Conductive concrete layer is formed between the ground plate made of metal material which is formed in close contact with the bottom surface in correspondence with the plane shape of the pole pole. The resistance is kept stable.

현행 가공 배전공사 시 가공지선과 완철 또는 피뢰기나 변압기 등과 같은 전주상에 설치되는 기기류 및 중성선의 대지 접지를 위한 접지공사를 시행함에 있어 접지동봉이나 심타봉 및 접지저항 저감제를 사용한 접지 시공법이 널리 적용되고 있다.Grounding method using grounding rod, core rod, and grounding resistance reducing agent is widely used in grounding work for earth grounding of equipments and neutral wires installed on poles such as processed ground wire and finished iron or lightning arrester or transformer. Is being applied.

현행 접지 시공법에 대해서 간략히 살펴보면, 접지동봉을 사용하는 접지 시공의 경우 접지동봉을 해머로 타격하여 매설한 후 전주 내부를 통하여 지표면 이하 1m 지점에 있는 전주의 접지선 인출구로부터 인출된 접지선과 접지동봉의 상부에 접지극 리드선을 연결하는 형태로 이루어지며, 이때 접지극 리드선은 지표면 이하 0.75m 이상 매설되도록 시공되고 있다. The current ground construction method is briefly described in the case of the grounding construction using the grounding rod, and the grounding rod is hit by the hammer and embedded in the ground. The ground electrode lead wire is connected to the ground electrode lead, and the ground electrode lead wire is constructed to be buried at least 0.75m below the ground surface.

또한, 접지선과 접지극 리드선과의 접속은 스리브 등에 의한 압축접속 또는 권부접속등의 방법으로 접속하며, 접지장소의 토질 또는 현장여건으로 인하여 규정된 접지저항치를 얻기 어려운 곳에서는 다극접지공법 또는 심타접지공법 등을 적용하거나, 접지개소 주변의 환경오염 우려가 없는 고강도 접지저항 저감제 등을 사용하여 시공하고 있는 것이 현실이다.In addition, the connection between the ground wire and the ground electrode lead wire is connected by compression connection or winding connection by a sleeve, etc., and the multi-pole grounding method or deep earthing method should be used where it is difficult to obtain the prescribed grounding resistance due to the soil or site conditions. It is a reality to use a high strength earth resistance reducing agent or the like that does not have the concern of environmental pollution around the grounding point.

이러한 접지공사는, 건주공사 완료 후 접지동봉을 매설하기 위해서는 추가로 굴착작업을 하여야 하고, 타격식 접지동봉을 매설하기 위해 인력 수공작업에 의존하여야 하며, 접지공사 시 원하는 접지저항치를 얻기가 쉽지 않으며, 경년변화에 따른 접지성능 저하로 정기적인 유지보수작업이 수반되는 문제점이 있는 것이다.Such grounding work requires additional excavation work in order to bury the grounding rod after completion of the construction work, and rely on manual labor for laying the impacting grounding rod. However, there is a problem that regular maintenance work is accompanied by deterioration of grounding performance due to secular variation.

이에 따라 본 발명 출원인은 2006년 특허출원 제113665호와 같이, 아치형 전주근가에 대하여 현행 접지공사에 사용되는 접지동봉이나 심타봉을 대체하는 접지판을 일체로 형성한 접지기능이 있는 아치형 전주근가를 이용하여, 접지공사를 위한 별도의 추가 굴착공정 없이 전주근가 장착공정과 동시에 접지공사가 효과적으로 이루어져 획기적으로 공정을 줄일 수 있는, 전주근가 장착 공정 시 접지공사를 병 행할 수 있는 접지판(Earth Plate) 일체식 전주근가를 제안한 바 있다.Accordingly, the applicant of the present invention, as in 2006 Patent Application No. 113665, the arch-shaped pole pole with a grounding function integrally formed with a ground plate to replace the ground rod or core rod used in the current grounding construction Earth plate to perform grounding work in the installation process of all-round roots, which can reduce the process drastically by making the grounding work effectively at the same time without additional additional excavation process for the grounding work. We have proposed an integrated Jeonju Root Price.

또한, 2007년 특허출원 제69478호와 같이 상기한 전주근가의 문제점을 개선한 아치형 전주근가를 제안하되, 전주근가의 양단 상측에는 양끝올림부를 각각 형성하고, 그 전주근가의 아치형 후측부는 보다 작은 외경을 갖도록 축소 형성하며, 아치형 전주근가의 중앙부를 관통하는 후크삽입공과 그 양측에 슬릿 형태의 볼트결합공을 이격 형성함으로써,In addition, as proposed in 2007 Patent Application No. 69478, the arch-shaped pre-tennis price is proposed to improve the above-mentioned problems of the perimeter, the upper end of each of the both ends of the rounded portion formed, respectively, the arcuate rear side of the pretend root By reducing the outer diameter and forming a hook insertion hole penetrating the center portion of the arcuate pole, and slit-shaped bolt coupling hole on both sides,

양끝올림부를 통해 토양과의 접지력을 향상시키면서도 보다 축소된 후측부를 통해 전주근가의 경량화를 꾀하는 것이며, 후크삽입공은 크레인을 이용한 전주근가의 이동 및 투입 작업의 용이함을 제공하고, 볼트결합공은 U볼트의 체결을 용이하도록 한 양끝 올림부를 갖는 건주공사용 아치형 전주근가를 안출한 바 있는 것이다.It is to reduce the weight of the electric pole around the lower side while improving the holding force with the soil through both ends, and the hook insertion hole provides the ease of movement and input work of the electric pole around the crane using the crane. It was conceived that arched electric pole roots for dry craftsmen with both ends raised to facilitate the fastening of U bolts.

그러나, 상기한 바와 같은 접지판을 갖는 전주근가의 경우 그 접지판에 대한 구체적인 구성이나 작용의 구체적인 언급이 없어서, 개량된 아치형 전주근가에 상기한 접지판을 적용하기 위해서는 그 전주근가의 형상과 일치하는 평면 형상을 갖추어야 하면서도, 그 접지판으로부터 인출된 리드선을 전주로부터 발생하는 접지선과 용이하게 연결할 수 있도록 하는 기술적 구성이 부여되어야 하는 것이다.However, in the case of the electric pole having a ground plate as described above, there is no specific configuration or operation of the ground plate, and in order to apply the ground plate to the improved arc-shaped pole pole, the shape of the pole pole is consistent with the shape of the pole pole It should be provided with a planar shape, but the technical configuration to be able to easily connect the lead wire drawn out from the ground plate with the ground wire generated from the pole.

이에 따라 본 발명 출원인은 2007년 특허출원 제07189호와 같이, 평면상 아치형 전주근가의 형상을 갖추면서도, 그 아치형 접지판으로부터 용융접합방식으로 인출되는 리드선을 구성하되, 이들 접지판은 평판형 또는 그레이팅형, 와플형과 같 이 다양하게 변경 적용하여 토양과의 접지력을 향상시키면서도, 전주의 접지선과 용이하게 연결 사용할 수 있게 하여,Accordingly, the applicant of the present invention, as in 2007 Patent Application No. 07189, forms a lead wire drawn out from the arced ground plate in a melt-bonding manner while having a shape of a flat arcuate pole, and the ground plates are flat or Various changes such as grating type and waffle type can be applied to improve the grounding force with the soil, and can be easily connected to the ground line of the pole.

콘크리트 타설에 의한 전주근가의 양생 제작시 그 접지판을 함께 결합시공함에 따라 우수한 생산성은 물론 전주근가의 설치 과정과 동시에 접지공사가 완료되므로 작업 효율성이 뛰어난 것이며, 토양과의 접촉 면적 및 접지 면적이 크게 향상되어 더욱 손쉽게 원하는 접지 저항값을 얻을 수 있어 접지 시공 작업의 편리성 및 효과가 극대화된 아치형 전주근가용 접지판을 제안한 바 있는 것이다.Since the grounding plate is combined with the ground plate when the curing of the electric pole by concrete pouring is completed, the grounding work is completed at the same time as the installation process of the electric pole, so the work efficiency is excellent. It has been greatly improved to obtain the desired ground resistance value more easily, and has proposed an arc-shaped all-pole ground plate that maximizes the convenience and effect of ground construction work.

그러나, 상기한 바와 같은 전주근가 및 그 접지판은 콘크리트로 이루어진 전주근가와 금속재로 된 접지판의 상호 결합력은 우수하나 금속재의 접지판이 토양의 성분에 따라 전식 등의 화학변화를 일으켜 표면 부식이 진행되어 기존의 접지시스템과 같이 동일하게 접지판의 기능이 약화되는 문제점을 갖고 있는 것이다.However, the electric pole and the ground plate as described above is excellent in the mutual bonding strength of the electric pole of the concrete and the ground plate of the metal material, but the ground plate of the metal material causes chemical changes such as erosion according to the soil composition, the surface corrosion progresses The problem is that the ground plate is weakened in the same way as the conventional grounding system.

또한, 금속재로 된 접지판은 기존 접지동봉 등의 시공방법과 같은 매설 상태이므로 고온 다습한 토양 내부 환경에 의해 쉽게 부식되므로 그 사용수명이 짧고 접지 효과가 약화되는 등의 문제점을 내포하고 있는 것이다.In addition, since the ground plate made of metal is buried under the same construction method as the existing grounding rod, it is easily corroded by the environment of high temperature and high humidity, so that the service life is short and the grounding effect is weakened.

본 발명은 전기한 바와 같은 문제점을 개선하고자 안출된 것으로서, 콘크리트 양생된 전주근가와 금속재로 된 접지판의 사이에 접지저감제로 사용되는 도전성 콘크리트층을 형성함으로써, 접지근가와 접지판의 결합력 향상은 물론 우수한 접지효과를 얻으면서도 경년변화가 거의 없고 전식 및 부식 방지 효과가 탁월하므로, 종래의 전주근가가 갖는 제반의 문제점을 극복할 수 있는 도전성 콘크리트층을 갖는 접지기능 아치형 전주근가를 제공함에 본 발명의 목적이 있는 것이다.The present invention has been made to improve the problems as described above, by forming a conductive concrete layer used as a ground reducing agent between the concrete cured pole and the metal ground plate, improving the bonding strength of the ground root and ground plate is Of course, there is almost no change in secular age and excellent corrosion and corrosion prevention effect while obtaining a good grounding effect, the present invention provides a grounding function arch type pole having a conductive concrete layer that can overcome the problems of conventional pole poles There is a purpose.

이상과 같은 본 발명 도전성 콘크리트층을 갖는 아치형 전주근가는, 도전성 콘크리트에 의해 전주근가 및 접지판을 결합 형성함에 따라 경년변화가 거의 없는 도전성 콘크리트가 갖는 우수한 접지 효과와 더불어 탁월한 접지 저항의 저감 효과를 얻게 되는 것이며, 전주근가와 접지판의 견고한 결합 및 금속재로 된 접지판의 부식을 방지하여 더욱 안정적이고 우수한 접지 효과를 기대할 수 있는 것이다.Arch-shaped electric pole root having a conductive concrete layer of the present invention as described above, as a combination of the electric pole root and the ground plate by the conductive concrete has excellent grounding effect of the conductive concrete with little change in secular age and excellent grounding resistance reduction effect It is possible to expect a more stable and excellent grounding effect by preventing the corrosion of the ground plate made of metal and the ground plate firmly coupled with the electric pole root and ground plate.

이하, 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described.

도 1은 본 발명에 따른 전주근가의 전체 사시도이고, 도 2는 본 발명에 따른 전주근가의 측단면도이다.1 is an overall perspective view of the electric pole muscle value in accordance with the present invention, Figure 2 is a side cross-sectional view of the electric pole muscle value in accordance with the present invention.

일반적으로 아치형 전주근가를 매설하기 위한 최소한의 굴착작업(오거크레인 및 백호우 등의 장비나 인력으로 모두 가능)을 완료한 후 U볼트를 이용하여 아치형 전주근가(10)를 전주에 장착하게 된다.In general, after completing the minimum excavation work (both with equipment or manpower such as auger crane and backhoe) to bury the arch type poles, the U-bolt is used to mount the arch type poles 10 to the pole.

이때, 아치형 전주근가(10)의 양단 상부에 돌출상의 양끝올림부(11)(11')가 형성되어 있으므로 상기한 양끝올림부(11)(11')는 되메움에 의한 토양과의 간섭 및 마찰면적을 크게 넓히는 작용을 하므로 결국 토양과의 결속력이 증대하는 전주는 더욱 안정적이고 견고한 설치상태를 유지할 수 있게 된다.At this time, since both protruding end portions 11 and 11 'are formed on both ends of the arcuate pole root 10, the both end portions 11 and 11' are interfering with soil due to backfilling. Since the friction area is greatly widened, the pole which increases the binding force with the soil can maintain a more stable and solid installation state.

또한, 본 발명의 아치형 전주근가는 그 외면에 형성되는 볼트삽입공(14)(14')을 형성하되, 그 볼트삽입공(14)(14')을 횡방향의 슬릿공으로 형성함에 따라 그 전주근가(10)를 전주에 장착하기 위한 U볼트의 조립 설치시, 상기한 U볼트를 보다 신속하게 삽입 및 고정 설치할 수 있는 장점을 갖게 된다.In addition, the arcuate pole root of the present invention forms a bolt insertion hole (14, 14 ') formed on the outer surface, the pole insertion as the bolt insertion hole (14, 14') is formed as a slit hole in the transverse direction When assembling and installing the U bolt for mounting the root 10 to the electric pole, it has the advantage that the above-described U bolt can be inserted and fixed more quickly.

이와 같은 전주근가(10)는 그 후측이 보다 축소 외경으로 된 외축소부(12)로 이루어져 있는 것인데, 외경이 축소 형태로 이루어져 있으므로 전체적인 중량이 크게 감소함에 따라 취급 및 설치의 용이함을 제공하게 되는 것이다.This front pole root 10 is made of an outer contraction portion 12 whose rear side is a reduced outer diameter, because the outer diameter is made of a reduced form to provide ease of handling and installation as the overall weight is greatly reduced. will be.

특히, 상기한 외축소부(12)의 중앙에는 횡상의 후크삽입공(13)이 관통 형성되어 있으므로 크레인을 이용한 아치형 전주근가(10)의 이동 및 설치작업시 그 전주근가를 더욱 편리하게 취급할 수 있게 한 것이다.In particular, since the transverse hook insertion hole 13 is formed in the center of the outer reduction part 12, it is more convenient to handle the forearm root when moving and installing the arch type pole root 10 using a crane. It was made possible.

이와 같은 아치형 전주근가(10)의 저면에는 금속판재로 된 다양한 형상의 접지판(20)이 위치하게 되는 것으로서, 본 발명에서는 상기한 아치형 전주근가(10)와 접지판(20)의 사이에 도전성 콘크리트층(30)을 형성함에 따라 상기한 도전성 콘크리트층(30)이 갖는 고유한 물성을 이용한 우수한 효과를 얻고자 하는 것이다.The ground plate 20 of various shapes made of a metal plate is located on the bottom surface of the arcuate pole root 10, in the present invention, between the arcuate pole pole 10 and the ground plate 20 is conductive. As the concrete layer 30 is formed, an excellent effect using the inherent physical properties of the conductive concrete layer 30 is to be obtained.

즉, 상기한 도전성 콘크리트층(30)에 사용되는 도전성 콘크리트는 특수한 탄소입자와 시멘트를 주성분으로 하고 있으며 땅속에 묻어두면 2~3일 내에 시멘트 및 콘크리트의 강도와 비슷한 강도로 굳어진 탄소판의 고체가 되며, 땅속에서는 부식이 되지 않고 물에 녹지 않아 반영구적인 접지전극으로 사용되고 있는 것이다.That is, the conductive concrete used in the conductive concrete layer 30 is composed of special carbon particles and cement as a main component and when buried in the ground becomes a solid of a carbon plate hardened to a strength similar to that of cement and concrete within two to three days. It is used as a semi-permanent grounding electrode because it does not corrode and dissolve in water in the ground.

특히 일단 굳어진 상태의 도전성 콘크리트는 동판과 유사한 양도체이며 영구적인 접지전극이 되는 것이다.In particular, the conductive concrete once hardened is a good conductor similar to the copper plate and becomes a permanent ground electrode.

그 밖에도 근자의 도전성 콘크리트는 무공해 접지를 가능케 하면서도 경년 변화가 거의 없으며 우수한 접지 효과를 갖고 있는 것이다.In addition, near-conducting concrete enables pollution-free grounding but has little secular variation and has an excellent grounding effect.

이에 따라 상기한 도전성 콘크리트층(30)에 의해 상측의 전주근가(10)와 하측의 접지판(20)을 결합시킴에 따라 하부 접지판(20)의 접지 효과를 향상시킬 수 있는 것이며, 접지판(20)과의 면접부분에는 부식이 발생하지 아니하므로 반영구적으로 그 접지판(20)의 접지 저항이 안정적으로 유지될 수 있게 하는 특징을 갖는다.Accordingly, the grounding effect of the lower ground plate 20 can be improved by combining the upper pole root 10 and the lower ground plate 20 by the conductive concrete layer 30 as described above. Corrosion does not occur in the interview portion with (20) has a feature that allows the grounding resistance of the ground plate 20 can be stably maintained permanently.

특히, 도 3 및 도 4의 도시와 같이 상기한 접지판(20)을 그레이팅 형상으로 제작하여 사용하는 경우 그레이팅 형상의 접지판(20)이 도전성 콘크리트층(30)의 내측으로 그 선단이 매립되게 함으로써, 그레이팅 형상의 접지판(20)이 갖는 우수한 접지 효과는 그대로 유지하면서도 접지판의 상당부분이 도전성 콘크리트층(30) 의 내부로 매립되므로 견고한 결합 상태의 유지 및 부식을 방지하는 효과가 탁월한 것이다.In particular, when the grounding plate 20 is manufactured in a grating shape as shown in FIGS. 3 and 4, the grating-shaped grounding plate 20 is embedded in the conductive concrete layer 30 with its tip embedded. By doing so, while maintaining the excellent grounding effect of the grounding plate 20 of the grating shape as it is, a substantial portion of the grounding plate is embedded in the conductive concrete layer 30 is excellent in the effect of maintaining a firmly bonded state and preventing corrosion .

또한, 도 5의 도시와 같이 상기한 접지판(20)을 와플 형상으로 제작하여 사용하는 경우에도 우수한 결합력의 확보는 물론 경년변화가 거의 없고 전식 및 부식 방지를 통해 안정적인 접지 능력을 유지할 수 있도록 할 수 있는 것이다.In addition, even when the ground plate 20 as shown in FIG. 5 is manufactured and used in a waffle shape, it is possible to maintain a stable grounding capability through securing of excellent bonding force and virtually no secular variation and preventing corrosion and corrosion. It can be.
