본 발명은 전주를 세워 설치하는 건주 공사시에 매립되는 전주근가 중 접지기능을 갖는 아치형 전주근가에 관한 것으로, 특히 강판과 동판으로 된 동복강판체가 배열 형성된 접지판을 도전성 콘크리트층을 갖는 아치형 전주근가에 매설 성형함으로써, 우수한 접지 성능과 경년변화에 대해 반영구적인 내구성을 갖는 효과를 기대할 수 있는 접지판 및 아치형 전주근가에 대한 것이다.The present invention relates to an arc-shaped pole pole having a grounding function among the pole poles buried in the construction of the construction of the pole pole, in particular, the arched pole pole pole having a conductive concrete layer of a ground plate formed of a steel plate and copper plate By embedding in the ground plate, the ground plate and the arc-shaped pole root can be expected to have the effect of excellent grounding performance and semi-permanent durability against secular variation.

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 시 공의 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. If you look at the current grounding method briefly, in the case of grounding construction using grounding rod, bury the grounding rod with hammer and bury it. The ground electrode lead wire is connected to the upper portion, 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 제113665호에 의한 접지판 일체식 아치형 전주근가와, 2007년 특허출원 제69478호에 의한 양끝 올림부를 갖는 건주공사용 아치형 전주근가를 안출한 바 있다.Accordingly, the applicant of the present invention devised an arch-shaped pole pole for dry works having a ground plate-integrated arch pole pole according to Patent Application No. 113665 in 2006 and both raised portions according to 2007 Patent Application No. 69478.

또한, 본 발명 출원인은 상기한 아치형 전주근가의 개량 출원으로서, 2007년 특허출원 제076189호에 의해 평면상 아치형 전주근가의 형상을 갖추면서도, 그 아치형 접지판으로부터 용융접합방식으로 인출되는 리드선을 구성하되, 이들 접지판은 평판형 또는 그레이팅형, 와플형과 같이 다양하게 변경 적용하여 토양과의 접지 력을 향상시키면서도, 전주의 접지선과 용이하게 연결 사용할 수 있게 하여,In addition, the applicant of the present invention is an improved application for the arcuate pole pole, and in 2007 patent application 076189, while having the shape of the arcuate pole pole in plan view, it constitutes a lead wire drawn out from the arcuate ground plate by the melt bonding method However, these ground plates can be used in various ways such as flat plate, grating type, and waffle type to improve the grounding force with the soil, and to easily connect and use the grounding lines of the poles.

콘크리트 타설에 의한 전주근가의 양생 제작시 접지기능을 부가하기 위해 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.When the ground plate is combined together to add grounding function in the curing of electric poles by concrete pouring, it has excellent productivity and excellent work efficiency because the grounding work is completed simultaneously with the installation process of electric poles. As the contact area and the ground area have been greatly improved, the desired ground resistance value can be more easily obtained, and therefore, an arc-shaped all-pole ground plate for maximizing the convenience and effect of ground construction work has been proposed.

또한, 본 발명 출원인은 2007년 특허출원 제108102호와 같이, 콘크리트 양생된 전주근가와 금속재로 된 접지판의 사이에 접지 저감제로 사용되는 도전성 콘크리트층을 형성함으로써, 접지근가와 접지판의 결합력 향상은 물론 우수한 접지효과를 얻으면서도 반영구적으로 경년 변화가 거의 없고 전식 및 부식 방지 효과가 탁월하므로, 종래의 전주근가가 갖는 제반의 문제점을 극복할 수 있는 도전성 콘크리트층을 갖는 접지기능 아치형 전주근가를 제안한 바 있다.In addition, the applicant of the present invention, such as 2007 Patent Application No. 108102, by forming a conductive concrete layer used as a ground reducing agent between the concrete cured pole root and the metal ground plate, thereby improving the bonding strength of the ground root and ground plate Of course, since the semi-permanent change and semi-permanent change and excellent anti-corrosion and corrosion prevention effect, the grounding function arch type electric pole with a conductive concrete layer can overcome the problems of conventional electric poles.

Proceeds with the problem that the grounding plate function is weakened in the same way as the existing 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 성능 및 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 rods, it is easily corroded by the environment of high temperature and high humidity, so that its service life is short and the grounding performance and effect are impaired. will be.

이상과 같은 본 발명 동복강판에 의한 접지판 및 그 접지판을 갖는 전주근가는, 도전성 콘크리트에 의해 전주근가 및 접지판을 결합 형성함에 따라 경년변화가 거의 없이 반영구적인 내구성이 있는 도전성 콘크리트가 갖는 우수한 접지 효과와 더불어 탁월한 접지 저항의 저감 효과를 얻게 되는 것이며, 지중 노출 상태의 동판부분과 이들 동판을 연결하고 있는 접지동대에 의해 부식 방지는 물론 더욱 안정적이고 우수한 접지 효과를 기대할 수 있는 것이다.As described above, the present invention has a ground plate made of copper-clad steel plate and a pole pole value having the ground plate, which is superior to that of the conductive concrete having semi-permanent durability with almost no secular variation as the pole pole value and the ground plate are combined and formed by conductive concrete.
