본 고안은 외주면에 폴리에칠렌층을 형성한 강관을 연결함에 있어서 일측 강관의 일단부에 팽경부를 형성하여 체결구의 접합부와 패킹의 접합부를 2단으로 형성하고 패킹의 접합부 내측으로 쐐기형의 패킹을 내삽하여 접합부의 외측으로 체결공을 형성한 2개로 분할된 체결구를 끼우고 타측에는 체결공을 형성한 원륜상의 체결구를 강판의 외측으로 끼워 타측 강관을 일측 강관의 평경부로 밀어넣어 체결구와 체결구를 서로 다수의 보울트 너트로 체결토록 하였으므로 접합되는 양강관 사이에서 고정되는 패킹의 위치가 항상 일정하고 강한 수압이나 외력에도 패킹 자체에 변형을 주지 않아 항상양접합강관 사이에 밀착되어 있으므로 수밀성과 밀봉효과가 우수하며 강관 내부의 유수(流水)가 누수될 염려가 없으며 작업을 신속하고 능률적으로 수행케 하는 강관 연결장치에 관한 것이다.The present invention is to connect the steel pipe with a polyethylene layer formed on the outer peripheral surface to form a bulge in one end of the steel pipe on one end to form a joint of the fastener and the joint of the packing in two stages, and insert the wedge-shaped packing inside the joint of the packing Insert the fastener divided into two to form the fastening hole on the outer side of the joint, and on the other side, insert the fastener in the ring which formed the fastening hole to the outside of the steel plate and push the other steel pipe into the flat part of the steel pipe to fasten it with the fastener. Since the balls are fastened with a number of bolt nuts to each other, the packing position fixed between the steel pipes to be joined is always constant, and because the packing itself is not deformed even under strong hydraulic pressure or external force, it is always in close contact between the two welded steel pipes. Excellent effect, no risk of water leakage inside the steel pipe and quick and efficient operation It relates to a steel pipe connecting device.
종래에는 강관과 강관을 연결함에 있어서 일측 강관이 내삽될 수 있도록 직경이 약간 크고 보울트 체결공이 형성된 체결편이 수개 외면에 돌설되고 편단이 나팔형으로 외향 만곡된 강관의 외관에 고무륜과 압압링이 외삽된 일측강관을 내삽하여 "∪"자형 보울트로 압압링의 걸림턱을 압착시켜 연결토록 한 강관 연결장치가 있었으나 체결 보울트가 앵커 보울트형이어서 그 단부가 압압링의 걸림턱에 걸리면서 압압링을 압착하므로 압압링의 압착상태가 견고 하지 못하여 연결상태가 불안정하였음은 물론 압압력이 약하여 내부소압이나 외력에 의하여 강관 내부의 유수가 누수될 염려가 있었으며 수밀성과 밀봉효과가 양호하지 못한 결점이 있었던 것이다.Conventionally, in connecting the steel pipe and the steel pipe, a fastening piece having a diameter slightly larger and a bolt fastening hole is formed on the outer surface so that one side of the steel pipe can be interpolated, and the rubber wheel and the pressure ring are extrapolated to the exterior of the steel pipe in which one end is curved outwardly in a trumpet shape. There was a steel pipe connecting device to insert the one-sided steel pipe and press the locking ring of the pressing ring with the "∪" shaped bolt, but the fastening bolt is anchor bolt type, so that the end is caught by the locking ring of the pressing ring. The pressure state of the pressure ring was not strong, so the connection was unstable, and the pressure was weak, so there could be water leakage inside the steel pipe by internal pressure or external force, and there was a defect that the watertightness and sealing effect were not good.
본 고안은 이와 같은 결점을 시정하기 위하여 보다 연결해체 작업이 간편 신속하고 수밀성과 밀봉효과를 높일수 있도록 한 것으로서 이를 첨부된 도면에 의하여 그 구조를 상세히 설명하면 다음과 같다. 일측 강관(1)의 일단부에 관체의 외경보다 조금 큰 직경을 가지는 돌륜부(2)와 돌륜부(2')를 2단으로 형성하고 돌륜부(2')의 내측에는 "＜"형의 요입부(4)를 형성한 원륜상의 패킹(3)을 내삽하여 일측 강관(1)의 돌륜부(2) 외측에 2개로 분할 형성되어 체결공을 가진 체결구(5)(5')를 감삽하여 일측의 양단 돌부(6)를 타측의 양단 요입부(6')에 끼워 보울트(7)로 체결하고 타측 강관(1') 단부에는 체결공을 가진 원륜상의 체결구(8)를 끼워 그 내측 쐐기형 돌륜부(9)가 요입부(4)에 감삽되게 하고 외측단부 확개요부에 철링(10)을 끼워 외측으로 다수의 보울트(11)를 체결하여 체결구(5)(5')와 체결구(8)를 스테이트 보울트(12)와 너트(12')로 체결토록 한 것을 특징으로 하는 것이다.The present invention is to facilitate the quick disconnection and to increase the watertightness and sealing effect in order to correct such defects as described in detail the structure by the accompanying drawings as follows. One end of one side of the steel pipe (1) is formed with two steps of the wheel wheel part 2 and the wheel wheel part 2 'having a diameter slightly larger than the outer diameter of the tube body, and the inner side of the wheel wheel part 2' has a "<" shape. Interpolating the annular packing (3) having the concave indentation (4) is inserted into two outside the wheel part (2) of one side steel pipe (1) to subtract the fastener (5) (5 ') having a fastening hole The two ends (6) on one end to the other end indentation (6 ') of the other side and tightened with a bolt (7) and the other end of the steel pipe (1') by inserting a circular ring fastener (8) with a fastening hole in the end The wedge-shaped wheel part 9 is inserted into the indentation part 4, and a plurality of bolts 11 are fastened to the outside by inserting the iron ring 10 in the outer end extension part and fastenings 5 and 5 '. It is characterized in that the fastener 8 is fastened with the state bolt 12 and the nut 12 '.
도면중 미설명부호 (13,13, 는 폴리에치렌층이다. 이와 같이 구성된 본 고안의 작용효과를 설명하면 일측 강관(1)의 돌륜부(2') 내측에는 원륜상의 패킹(3)을 내삽하고 돌륜부(2)의 외측에는 체결공을 가진 체결구(5)(5')을 감설하여 체결구(5')의 양단 요입부(6')에 체결구(5)의 양단 돌부(6)를 끼워 맞추어 보울트(7)로 체결하고 타측 강관(1')의 외측에는 체결공을 가진 원륜상의 체결구(8)을 감삽하여 쐐기형 돌륜부(9)를 요입부(4)에 감삽되게 밀어넣으면 상측 돌륜부(9') 내측으로 돌륜부(2')의 단부가 감입In the drawings, reference numerals 13 and 13 denote polyethylene layers, which describe the effect of the present invention configured as described above, and interpolate the annular packing 3 inside the protrusion 2 'of the steel pipe 1. In addition, the fasteners 5 and 5 'having fastening holes are reduced in the outer side of the wheel part 2, and both end protrusions 6 of the fastener 5 are inserted into the recesses 6' at both ends of the fastener 5 '. ) And fasten with bolts (7), and on the outside of the other steel pipe (1 ') by inserting a fastener (8) of a circular ring having a fastening hole so that the wedge-shaped protrusion (9) to be inserted into the indentation (4) When pushed in, the end of the protrusion 2 'is inserted into the upper protrusion 9'.
이와 같이 본 고안은 일측강관의 돌륜부에 감삽되는 패킹의 고정상태가 견고하여 패킹의 위치가 항상 일정하고 강한 수압이나 외력에도 패킹 자체에 변형을 주지 않아 항상 양쪽 접함 강관 사이에 밀착되어 있으므로 수밀성과 밀봉 효과가 우수하여 강관 내부의 누수될 염려가 없으며 연결해체 작업을 능률적으로 수행케 하는 실용적인 유용한 고안이다.As such, the present invention has a rigid fixed state of the packing which is inserted into the wheel part of one side of the steel pipe, so that the packing is always constant and does not deform the packing itself even under strong water pressure or external force. With excellent sealing effect, there is no risk of leakage inside the steel pipe, and it is a practical and useful design to efficiently perform the disconnection work.
