건축물내의 지중케이블 파형보호관 연결구조{A connecting structure of a wave type protective pipe for a cable in a building}A connecting structure of a wave type protective pipe for a cable in a building}

본 발명은 건축물내의 지중케이블 파형보호관 연결구조에 관한 것으로서, 더욱 상세하게는 지중케이블을 보호하기 위한 파형보호관을 쉽게 고정할 수 있게 하고, 내부로 수분이 침투하게 되면 수용성발포링이 팽창하여 입구를 막게 하여 완전한 수밀이 되게 하며, 견고하게 고정할 수 있어 접속작업이 매우 간편하게 이루어지는 건축물내의 지중케이블 파형보호관 연결구조에 관한 것이다.The present invention relates to the underground cable corrugated protective tube connection structure in a building, and more particularly, it is possible to easily fix the corrugated protective tube for protecting the underground cable, and when water penetrates into the water-soluble foam ring expands the inlet It is related to the underground cable corrugated protective tube connection structure in a building, which is made to be completely watertight and to be firmly fixed, thereby making the connection work very easy.

일반적으로 공동주택 단지의 지하 공동구는 다수개의 콘크리트 박스가 연결되어 내부에 전력선 및 통신선 등이 설치되거나 배관 라인이 설치된다.In general, underground joint wards of multi-unit housing complexes are connected with a plurality of concrete boxes, and power lines and communication lines are installed therein or plumbing lines are installed.

다수개의 콘크리트 박스가 길이방향으로 연결되는 지하공동구는 이음부에 대한 누설을 방지하기 위해 실링재 및 외벽 보호 미장 구조를 가지지만 이음부가 견고하게 처리되지 않는 경우 바닥 물고임의 문제점을 갖는다.The underground cavity, in which a plurality of concrete boxes are connected in the longitudinal direction, has a sealing material and an outer wall protection plastering structure to prevent leakage to the joint, but has a problem of floor trapping when the joint is not firmly treated.

이러한 콘크리트 박스는 대부분 지중에 설치되는 바, 토사층이 주위를 둘러싸고 있는 관계로 지하수가 이음부를 통해 유입되기 때문이다. 종래에는 맨홀에서 분기되는 지중케이블을 보호하는 파형보호관 이음부에 실링재를 감싸는 구조로 코 킹하는 단순 구조로 시공하게 되므로 이들 파형보호관이나 배관파이프 이음부에서 누수 현상이 빈번하게 발생되는 문제점이 있다.Most of these concrete boxes are installed in the ground because the groundwater flows through the joints because the soil layer is surrounding. Conventionally, since the construction is a simple structure to be cocked in a structure that wraps the sealing material to the corrugated protective pipe joint to protect the underground cable branching from the manhole, there is a problem that frequently occurs in these corrugated protective pipe or pipe pipe joint.

이를 방지하고자 종래에는 콘크리트 박스의 벽체 일측면 바닥에 소정의 두께만큼 1차 콘크리트를 타설한 후 콘크리트박스에 분기되는 파형보호관이 연결되는 연결부를 별도의 실링재로 밀봉되게 코킹한 후 상기 파형보호관의 타측단에 연결소켓을 조립하여 상기 연결소켓에 또 다른 파형보호관이 조립되도록 길게 연결하여 그 내측으로 지중배선용 케이블이 끼워지도록 배선한 다음 이들 연결부를 콘크리트를 이용하여 2차 타설하는 시공방법이 널리 이용되었다.In order to prevent this, in the related art, after pouring the primary concrete to the bottom of one side of the wall of the concrete box by a predetermined thickness, the connector connecting the corrugated protective tube branching to the concrete box is sealed with a separate sealing material and then the other of the corrugated protective tube. The construction method of assembling the connection socket at the side end, connecting the corrugated protection tube to the connection socket for a long time, and wiring the underground wiring cable to the inside thereof, and then placing the connection secondary using concrete was widely used. .

하지만 파형보호관이 연결되는 연결부의 고정상태가 견고하지 않으면 콘크리트 타설시 처짐현상으로 인해 파형보호관의 연결부가 초기 상태를 유지하지 못하고 처지는 현상이 있고 그 정도가 심한 경우에는 단락되게 되어 케이블 배선을 어렵게 하는 문제점이 있고, 이들 단락된 틈새로 물이 유입시에는 감전 사고를 유발하는 등의 원인을 제공하기도 한다.However, if the connection of the corrugated protective tube is not firmly fixed, the connection part of the corrugated protective tube cannot be maintained due to deflection during concrete pouring. There is a problem, and when water enters into these short-circuited gaps, it may provide a cause such as an electric shock accident.

이러한 전기 누전에 의한 감전사고는 매년 몇 차례씩 반복적으로 발생하게 되는 문제점이 지적되었지만 그에 따른 특별한 대안을 제시하지 못하고 있는 실정이다.The electric shock caused by the electrical leakage has been pointed out a problem that occurs repeatedly several times each year, but it does not present a special alternative accordingly.

따라서 두개의 파형보호관을 서로 연결할 때, 수밀이 확실하게 되어 내부로 물이 침투하지 못하게 하고, 연결이 간편한 구조가 필요하게 되었다.Therefore, when connecting two corrugated protective tubes to each other, watertightness is ensured so that water does not penetrate into the inside and a structure that is easy to connect is required.

본 발명은 서로 연결하려는 파형보호관(1) 양단에 체결관(10)을 고정하고, 체결관(10)이 끼워진 파형보호관(1) 외경에 형상기억와이어(20)를 고정하며, 체결관(10)의 후단 외경에 수용성발포링(30)을 끼워 수밀되게 하고, 연결관(40)으로 체결관(10)에 고정하여 파형보호관(1)의 단부를 보호하면서 수밀되게 연결시키는 것을 주요 구성으로 한다. The present invention is to fasten the fastening pipe 10 to both ends of the corrugated protective pipe (1) to be connected to each other, to fix the shape memory wire 20 to the outer diameter of the corrugated protective pipe (1) in which the fastening pipe 10 is fitted, the fastening pipe (10) The water-soluble foaming ring 30 is fitted into the rear end outer diameter of the watertight watertight, and the watertight foam ring 30 is fixed to the fastening pipe 10 by the connecting pipe 40 to protect the end of the corrugated protective pipe 1 while being watertightly connected. .

본 발명에서 연결하려는 파형보호관(1)은 중공의 관체에 나선형 홈부가 내외측에 서로 엇갈리게 형성되고, 내부에 지중케이블이 내장되어 보호된다.In the present invention, the corrugated protective tube 1 to be connected to the hollow groove is formed with the spiral grooves alternately in and out of each other, the underground cable is embedded therein and protected.

파형보호관(1)의 단부 내경에 삽입되어 고정되는 체결관(10)은 중공부가 형성된 관체(11)의 외경에 나선형돌기(13)가 형성되고, 나선형돌기(13)는 전단(12)에서 후단으로 갈수록 직경이 커지도록 형성된다. 전단(12)에 위치하는 나선형돌기(13)의 직경은 파형보호관(1)의 직경보다 작게 형성되어 쉽게 삽입되고, 체결관(10)의 후단으로 갈수록 직경이 크게 형성되어 파형보호관(1)의 내경에 밀착되어 고정된다. 즉 체결관(10)이 회전되면서 나선형돌기(13)가 파형보호관(1) 내경의 홈에 삽입되어 끼워지는데, 후단으로 갈수록 커지는 나선형돌기(13)의 직경에 의해서 파형보호관(1)의 내경에 밀착되게 된다.The fastening tube 10 inserted into and fixed to the inner diameter of the end portion of the corrugated protective tube 1 has a spiral protrusion 13 formed at the outer diameter of the hollow body 11 having the hollow portion, and the spiral protrusion 13 has a rear end at the front end 12. It is formed so as to increase in diameter. The diameter of the spiral protrusion 13 positioned at the front end 12 is smaller than the diameter of the corrugated protective tube 1 and is easily inserted. The diameter of the spiral protrusion 13 is larger than the rear end of the fastening tube 10 so that the diameter of the spiral protrusion 13 is increased. It is fixed in close contact with the inner diameter. That is, as the fastening tube 10 rotates, the spiral protrusion 13 is inserted into the groove of the inner diameter of the corrugated protective tube 1, and is inserted into the groove of the corrugated protective tube 1 by the diameter of the spiral protrusion 13 that increases toward the rear end. It will be in close contact.

체결관(10)의 관체(11)의 후단에 나사산(14)이 형성되고, 관체(11)의 전단(12)이 파형보호관(1)의 단부 내측으로 삽입되어 고정되되 파형보호관(1)의 나선형 내측 홈부에 관체(11)의 나선형돌기(13)가 끼워져 고정된다.A screw thread 14 is formed at the rear end of the tube 11 of the fastening tube 10, and the front end 12 of the tube 11 is inserted into and fixed to the end of the corrugated tube 1. The helical protrusion 13 of the tubular body 11 is fitted and fixed to the helical inner groove part.

체결관(10)이 끼워진 파형보호관(1)의 외측홈부에 형상기억와이어(20)가 끼워져 고정되고, 형상기억와이어(20)는 가열한 상태에서 직경이 늘어나고 상온에서 줄어드는 성질을 가지도록 형성되어 파형보호관(1) 외측을 상온에서 압축하여 밀착시키게 된다.The shape memory wire 20 is inserted into and fixed to the outer groove of the corrugated protective tube 1 in which the fastening tube 10 is inserted, and the shape memory wire 20 is formed to have a diameter that increases in a heated state and decreases at room temperature. The outer surface of the corrugated protective tube 1 is compressed at room temperature to be in close contact.

파형보호관(1)의 외측으로 나선형으로 형성된 형상기억와이어(20)를 회전시켜 고정시킬때, 형상기억와이어(20)를 가열시켜 직경을 늘린 다음 끼워넣는다. 이때 가열하는 온도는 60도에서 80도 사이의 온도로 가열하면 직경이 늘어나게 형상을 기억시켜 파형보호관(1)에 고정한다.When rotating and fixing the shape memory wire 20 spirally formed to the outside of the corrugated protective tube 1, the shape memory wire 20 is heated to increase the diameter and then inserted. At this time, when the heating temperature is heated to a temperature between 60 degrees and 80 degrees, the shape is increased so that the diameter is increased, and it is fixed to the corrugated protective tube 1.

체결관(10)의 후단에서 나선형돌기(13)와 나사산(14) 사이에 끼워지는 수용성발포링(30)은 원형 링 형상으로 제조되어 체결관(10)에 끼워진다. 이러한 수용성발포링(30)은 물에 의해 발포 팽창되어 연결관(40)의 덮개부(43) 내측 공간을 채워 밀폐시킨다.At the rear end of the fastening pipe 10, the water-soluble foam ring 30 fitted between the spiral protrusion 13 and the thread 14 is manufactured in a circular ring shape and fitted to the fastening pipe 10. The water-soluble foam ring 30 is expanded and foamed by water to fill the inner space of the cover portion 43 of the connecting pipe 40 to seal.

따라서 물이 연결관(40)의 내부로 침투되어 들어오게 되면 수용성발포링(30)이 발포되어 팽창되어 수밀되게 된다.Therefore, when water penetrates into the connection pipe 40, the water-soluble foam ring 30 is expanded to be watertightly expanded.

연결관(40)은 중공의 관체(41) 양측으로 덮개부(43)가 형성되고, 덮개부(43)는 관체(41)의 중앙부보다 직경이 크게 형성되어 단턱부(44)가 형성된다. 단턱부(44)에 의하여 형성된 공간부에 파형보호관(1)의 단부가 삽입되고, 공간부로 물이 들어오게 되면, 수용성발포링(30)이 팽창하여 수밀시키게 된다.The connecting pipe 40 has a cover part 43 formed on both sides of the hollow tube body 41, and the cover part 43 has a larger diameter than the central part of the tube body 41, so that the step portion 44 is formed. When the end of the corrugated protective tube 1 is inserted into the space portion formed by the stepped portion 44 and water enters the space portion, the water-soluble foam ring 30 is expanded and watertight.

연결관(40) 관체(41)의 중앙부 내경에 나사산(42)이 형성되어 양측으로 체결관(10)이 고정되고, 덮개부(43)의 내측으로 체결관(10)이 삽입된 파형보호관(1)이 위치하여 보호된다. 연결관(40)의 중앙부 내경에 형성되는 나사산(42)은 양측에서 삽입되는 체결관(10)의 나사산(14)과 결합되도록 서로 다른 방향으로 형성된다. 따라서 연결관(40)을 일측 방향으로 돌리면 두개의 파형보호관(1)에 고정된 체결관(10)의 나사산(14)과 동시에 체결되고, 타측 방향으로 돌리면 두개의 체결관(10)이 연결관(40)에서 분리된다.Corrugated protective tube in which a screw thread 42 is formed at the inner diameter of the center portion of the connecting tube 40, and the fastening tube 10 is fixed to both sides, and the fastening tube 10 is inserted into the cover 43. 1) This location is protected. Threads 42 formed in the inner diameter of the central portion of the connecting pipe 40 are formed in different directions to be coupled to the threads 14 of the fastening pipe 10 inserted from both sides. Therefore, when the connecting pipe 40 is turned in one direction, the screw 14 of the fastening pipe 10 fixed to the two corrugated protective pipes 1 is simultaneously engaged, and in the other direction, the two fastening pipe 10 is connected to the connecting pipe. Are separated at 40.
