본 발명은 케이블 및 그 부속재 등이 수용되어 접속되는 공동주택용 터널식 전력구 접지장치에 관한 것으로, 더욱 상세하게는 터널식 전력구 내에 설치되는 송배전용 케이블 또는 통신용 케이블의 접지 작업을 용이하게 할 수 있는 접지구조에 관한 것이다.The present invention relates to a tunnel-type power outlet grounding device for a multi-family house in which the cable and its accessories are accommodated and connected. More particularly, the grounding operation of the transmission / distribution cable or communication cable installed in the tunnel-type power outlet can be facilitated. It relates to a grounding structure.

일반적으로, 전력구는 송배전용 전력선 또는 통신선 등과 같은 다회선의 케이블 및 그 부속재 등을 수용하고 케이블의 접속공간을 구비한 구조물로서, 크게 개착식 및 터널식으로 구분된다.In general, a power outlet is a structure for accommodating a cable of multiple lines such as a power transmission line or a communication line for communication and the like and its accessories, and having a connection space for cables.

개착식 전력구는 도로를 계획된 심도(深度)까지 굴착하여 전력구를 설치하고 되메우기 하는 형태의 전력구를 말하고, 터널식 전력구는 도로를 굴착하지 않고 지 하 공간에 구조물을 설치하는 형태의 전력구를 일컫는다. 이 중 특히 도로를 굴착하지 않는 터널식 전력구에 있어서 콘크리트 세그먼트 링을 이용한 세그먼트형 터널식 전력구의 적용이 확대되고 있는 추세이다.Retractable power bulbs are those that excavate the road to a planned depth and install and replenish them. Tunneled bulbs are structures that install structures in underground spaces without digging roads. . Among them, the application of the segmented tunnel-type power bulb using the concrete segment ring is increasing in the tunnel-type power bulb that does not excavate the road.

한편, 터널식 전력구에는 콘크리트 재질로 이루어진 암거 형태의 전력구가 널리 이용되었지만, 최근에는 각종 소음 및 진동 등의 건설 공해를 최소화할 수 있는 세그먼트 링을 이용한 세그먼트형 터널식 전력구가 적용되고 있는 추세이다.On the other hand, culvert-type power bulbs made of concrete are widely used for tunnel-type power tools, but recently, segment-type tunnel-type power tools using segment rings are being applied to minimize construction pollution such as various noises and vibrations. .

이러한 세그먼트형 터널식 전력구는 지중을 터널형태로 파낸 뒤 터널 내측에 원주방향으로 분할된 다수의 세그먼트 링을 밀착 조립하여 얻어지고, 이러한 다수의 세그먼트 링으로 이루어진 터널식 전력구의 내부에는 다수의 선반이 설치되고, 각 선반에는 다회선의 송배전용 전력케이블 또는 통신용 케이블이 포설된다.Such a segmented tunnel-type power bulb is obtained by digging underground into a tunnel shape and then assembling a plurality of segment rings circumferentially arranged inside the tunnel, and a plurality of shelves are installed inside the tunnel-type power bulb formed of such a plurality of segment rings. Each shelf is equipped with a multi-wire power cable or communication cable.

한편, 이러한 터널식 전력구 내에 수용되는 케이블들은 접지가 필수적으로 요구되며, 이러한 접지공사시에는 기준저항치, 접지대상, 주위여건, 공사의 난이성 및 경제성 등을 고려하여 시공한다.On the other hand, the cables accommodated in the tunnel-type power port is required to be grounded, and when the grounding work is constructed in consideration of the reference resistance value, grounding target, ambient conditions, construction difficulty and economic efficiency.

이와 같이 케이블을 접지하기 위한 종래 국내 공개특허 제10-2006-0081731호(명칭, 터널식 전력구의 접지구조)는 첨부도면 도 1에 도시된 바와 같이 원호형상으로 성형된 세그먼트 링(20)의 외주면 상에 전도체 재질의 접지판(21)이 설치되어 있었고, 각 접지판(21)에는 세그먼트 링(20)을 관통하는 접지돌기(22)가 설치되어 있었으며, 이웃한 접지돌기(22)는 연결도선(23)에 의해 통전 가능하게 접속되어 있었다.As described above, the conventional Korean Patent Publication No. 10-2006-0081731 (namely, the grounding structure of the tunnel-type power bulb) for grounding the cable is formed on the outer circumferential surface of the segment ring 20 formed in an arc shape as shown in FIG. A ground plate 21 made of a conductive material was installed in each ground plate, and each ground plate 21 was provided with a grounding protrusion 22 penetrating through the segment ring 20, and the adjacent grounding protrusions 22 were connected to a connecting wire ( 23) was connected to enable energization.

그러나, 이와 같은 종래 터널식 전력구의 접지구조는 연결도선(23)이 외부로 노출되어 있기 때문에 터널식 전력구의 내부 미관을 해치는 단점이 있었고, 특히 접지돌기(22) 간을 연결도선(23)으로 연결하는 별도의 작업을 필요로 하므로 작업이 매우 불편하게 되는 문제점을 갖고 있었다.However, such a grounding structure of the conventional tunnel-type power bulb has a disadvantage in that it damages the internal aesthetics of the tunnel-type power bulb because the connection wire 23 is exposed to the outside, and in particular, the connection between the ground protrusions 22 with the connection wire 23. Since a separate work is required, the work was very inconvenient.

또한, 종래 터널식 전력구의 접지구조는 세그먼트 링(20)의 외주면 상에 설치된 전도체 재질의 접지판(21)이 평평한 면으로 되어 있었기 때문에 토사와의 결합력이 떨어져 터널 붕괴의 염려가 있었다.In addition, the grounding structure of the conventional tunnel-type power bulb has a ground plane 21 made of a conductor material provided on the outer circumferential surface of the segment ring 20, so that the coupling force with the soil is reduced, causing a tunnel collapse.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 터널식 전력구의 접지작업을 보다 편리하게 할 수 있으며, 터널의 결합력을 향상시켜 터널의 강도를 증대시킬 수 있는 공동주택용 터널식 전력구 접지장치를 제공함에 있다.The present invention has been made to solve the above problems, the purpose of which is to make the grounding of the tunnel-type power bulb more convenient, and can improve the strength of the tunnel to increase the strength of the tunnel tunnel-type power bulb for the apartment house To provide a grounding device.

Overlapping with each other, and an arc-shaped conducting bar 50 having a fastening hole 52 formed at the center thereof is inserted into the cutout 33, so that the adjacent perforated grounding plate 40 contacts the conducting bar 50. Steps formed on the other end of the perforated ground plate 40 and the concrete block 30 through the through holes 47 and 37 which are centered with the fastening holes 52 formed in the perforated ground plate 40. The stud bolt 60 formed at the one end of the concrete block 30 by passing through the fastening hole 52 and the through hole 47 and 37 is formed on the mold tuck 34 to fit the cylinder type washer 62. Secure with nut (64).

또, 콘크리트블록(30)의 타측에 형성된 계단형턱(34)에는 타공접지판(40)의 두께와 동일한 깊이로 자리파기턱(39)을 형성하여 타공접지판(40)이 계단형턱(34)에 밀착되었을 때 타공접지판(40)의 면과 계단형턱(34)의 면이 일치하도록 한다.In addition, the stepped jaw (34) formed on the other side of the concrete block (30) to the same depth as the thickness of the perforated grounding plate (40), the perforated grounding plate (40) is a stepped jaw (34) When in close contact with the surface of the perforated ground plate 40 and the surface of the stepped jaw 34 to match.

그리고, 콘크리트블록(30)의 부착면(36)에 설치되는 타공접지판(40)은 접착에 의해 콘크리트블록(30)에 부착되며, 타공접지판(40)에 설치되는 보강와이어(42)와 접지핀(46) 및 스터드볼트(60)는 모두 용접에 의해 타공접지판(40)에 영구적으로 접합되고, 타공접지판(40)에 형성된 천공구멍(44)은 콘크리트블록(30)에 의해 터널을 형성할 때 토사가 유입되도록 하여 결합력을 더욱 향상시키는 작용을 한다.In addition, the perforated ground plate 40 installed on the attachment surface 36 of the concrete block 30 is attached to the concrete block 30 by adhesion, and the reinforcing wire 42 installed on the perforated ground plate 40 and The ground pin 46 and the stud bolt 60 are both permanently bonded to the perforated ground plate 40 by welding, and the perforated hole 44 formed in the perforated ground plate 40 is tunneled by the concrete block 30. When forming the soil to be introduced to act to further improve the bonding force.

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도9에 도시된 바와 같이 콘크리트블록(30)의 볼록한 부착면(36)에 접착제를 도포한 다음 타공접지판(40)을 콘크리트블록(30)의 부착면(36)에 밀착시키게 되면, 타공접지판(40)이 콘크리트블록(30)의 부착면(36)에 접착된다.As shown in FIGS. 2 to 9, an adhesive is applied to the convex attachment surface 36 of the concrete block 30, and then the perforated ground plate 40 is closely attached to the attachment surface 36 of the concrete block 30. If so, the perforated ground plate 40 is bonded to the attachment surface 36 of the concrete block 30.

이후 콘크리트블록(30)의 일측단에 위치된 계단형턱(32)에 형성된 절개 부(33)에 통전바(50)을 삽입하게 되면, 타공접지판(40)의 일측단에 설치된 스터드볼트(60)가 통전바(50)에 형성된 체결구멍(52)을 통해 돌출된다.After inserting the conduction bar 50 into the cutout portion 33 formed in the stepped jaw 32 located at one end of the concrete block 30, the stud bolt 60 is installed at one end of the perforated ground plate 40 ) Is projected through the fastening hole 52 formed in the energizing bar (50).

그 다음 이웃하는 콘크리트블록(30)의 타측단에 형성된 계단형턱(34)을 이웃한 콘크리트블록(30)의 일측단에 형성된 계단형턱(32)에 맞추어 밀착시키면서 스터드볼트(60)을 타공접지판(40)과 콘크리트블록(30)의 타측단에 형성된 관통구멍(37)(47)으로 삽입하게 되면, 이웃한 콘크리트블록(30)이 맞물린 상태로 결합되고, 스터드볼트(60)는 콘크리트블록(30)을 통해 돌출된다.Then the stud bolt 60 is perforated ground plate while closely contacting the stepped jaw 34 formed at the other end of the neighboring concrete block 30 to the stepped jaw 32 formed at one end of the neighboring concrete block 30. When inserted into the through holes 37 and 47 formed at the other end of the 40 and the concrete block 30, the neighboring concrete block 30 is coupled in an engaged state, the stud bolt 60 is a concrete block ( Protrude through 30).

이때 콘크리트블록(30)을 통해 돌출된 스터드볼트(60)에 실리더형와셔(62)를 끼운 다음 너트(64)로 조이게 되면, 이웃한 콘크리트블록(30)이 강하게 결합되며, 이웃한 타공접지판(40)의 사이에 위치된 통전바(50)와 타공접지판(40)이 너트(64)에 의해 강하게 압축되어 밀착되기 때문에 통전저항이 크게 줄어들게 되고, 이웃한 타공접지판(40) 끼리 접지된 상태가 되어 이웃한 타공접지판(40)끼리 연결하는 별도의 접지 공사가 필요 없게 된다.At this time, when the cylinder type washer 62 is inserted into the stud bolt 60 protruding through the concrete block 30 and then tightened with the nut 64, the neighboring concrete block 30 is strongly coupled to the neighboring ground hole. Since the energizing bar 50 and the perforated ground plate 40 positioned between the plates 40 are strongly compressed and closely adhered by the nut 64, the conduction resistance is greatly reduced, and the neighboring perforated ground plates 40 are It becomes a grounded state, so that no separate grounding work is required to connect the neighboring perforated ground plates 40 to each other.

한편, 콘크리트블록(30)의 부착면(36)에 설치된 타공접지판(40)은 토사와 접촉되어 토압을 견디는 동시에 타공접지판(40)에 형성된 천공구멍(44)으로 유입된 토사에 의해 결합력을 유지하고, 더욱이 천공구멍(44)을 가로방향와 세로방향으로 가로지르도록 설치된 보강와이어(42)에 의해 토사와의 결속력을 더욱 증대되며, 천공구멍(44)의 사이사이에 위치된 접지핀(46)은 토사에 박혀 타공접지판(40)으로 흐르는 전류를 대지로 흘려보내는 작용을 한다.On the other hand, the perforated ground plate 40 installed on the attachment surface 36 of the concrete block 30 is in contact with the soil and withstands the earth pressure and at the same time by the cohesion force introduced into the punching hole 44 formed in the perforated ground plate 40 In addition, the binding force with the earth and sand is further increased by the reinforcing wires 42 installed to cross the perforations 44 in the horizontal and longitudinal directions, and the ground pins disposed between the perforations 44. 46) is embedded in the earth and sand to flow the current flowing to the ground plate 40 to the ground action.

또한, 타공접지판(40) 자체가 통전이 가능한 동판으로 만들어져 있기 때문에 타공접지판(40)이 접지체 역할을 하게 된다.In addition, since the perforated ground plate 40 itself is made of a copper plate that can conduct electricity, the perforated ground plate 40 serves as a grounding body.

이상에서 설명한 바와 같은 본 발명은 콘크리트블록 간의 통전을 위한 별도의 접지공사를 할요로 하지 않고 콘크리트블록을 시공하는 과정에서 간단히 통전이 이루어지도록 구성되어 있기 때문에 시공이 매우 간편하게 되고, 공기를 크게 단축시킬 수 있는 효과가 있으며, 기존과 같이 접지선이 콘크리트블록의 외부로 돌출되는 구조로 되어 있지 않고 내측에 매립된 통전바에 의해 이웃한 콘크리트블록의 타공접지판 간에 통전이 이루어지는 구조로 되어 있기 때문에 외관을 깔끔하게 마무리할 수 있는 효과가 있다.As described above, the present invention does not require a separate grounding work for energizing the concrete blocks, and thus, the construction is very simple, because the electric current is simply made in the process of constructing the concrete blocks, and greatly shortens the air. It has the effect that the ground wire does not protrude to the outside of the concrete block like the existing one, but the structure is made to conduct electricity between the perforated ground plates of the neighboring concrete blocks by the energized bar embedded inside. It is effective to finish.

더 나아가서 본 발명은 콘크리트블록의 볼록한 부착면에 설치되는 타공접지판이 동판으로 성형되어 있기 때문에 콘크리트블록의 보다 넓은 면적을 활용하여 접지할 수 있게 되어 접지저항을 크게 줄이고 대지로의 방전을 원활하게 할 수 있는 효과가 있다.Furthermore, since the perforated ground plate installed on the convex attachment surface of the concrete block is formed of copper plate, the present invention can be grounded by utilizing a larger area of the concrete block, thereby greatly reducing the grounding resistance and smoothing the discharge to the ground.
