"The inner surface of the cylindrical ring-shaped packing has grooves formed at regular intervals so as to form an arc-shaped melted portion, but the melted portions at both ends are formed longer than the inner melted portion, and the outer surface is formed with both middle recesses. Type overhang and " "Form a protrusion to the outer circumference" "∩" type locking recesses on both sides of the inner side of the connecting pipe forming the wheels to form the recesses of the " "Type" projection and " "The type of joints are pushed into the both ends of the connection pipe by subtracting the protrusions, and the iron ring is inserted into the expansion-recessed both ends of the connection pipe to be fastened with a number of bolt nuts from the outside.
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 견고하지 못하여 연결상태가 불안정하였음은 물론 압압력이 약하여 내부 수압이나 외력에 의하여 강관 내부의 유수가 누수될 염려가 있었으며 시공작업이 번거롭고 수밀성과 밀봉 효과가 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 for crimping the locking ring of the pressing ring by inserting one side steel pipe into the "∪" shaped bolt, but the fastening bolt is anchor bolt type, so the end is caught by the locking ring of the pressing ring, The connection of the press ring was not strong and the connection was unstable, and the pressure was weak.Therefore, there was a risk of water leakage inside the steel pipe due to internal water pressure or external force, and the construction work was cumbersome and the watertightness and sealing effect were not good. It was.
본 고안은 이와 같은 종래의 결점을 시정하여 보다 연결해체 작업이 간편 신속하고 수밀성과 밀봉효과를 높일 수 있도록 한 것으로서 이를 첨부된 도면에 의거하여 그 구조를 상세히 설명하면 다음과 같다.The present invention is to correct the above-mentioned drawbacks so that the connection and disassembly operation can be more easily and quickly, watertightness and sealing effect as described in detail based on the accompanying drawings as follows.
단면이 "" 형의 원륜 상으로 된 패킹(1)(1')의 내측면에는 다수의 호형상 융출부(2)(2')가 형성되게 요홈(3)(3')을 일정한 간격으로 형성하되 양단의 융출부(4)(4')를 내측의 융출부(2)(2')보다 길게 형성하고 외측면에는 중간요입부(5) 양쪽으로 "∩" 형 돌출부(6)와 ""형 돌출부(6')를 형성하여 외주면으로 사다리꼴형의 요입부(7')가 형성되게 원륜상의 돌륜(7")을 형성한 연결관(7)의 내측 양쪽의 "∩"형 걸림요입부(8)(8')과 ""형 걸림요입부(9)(9')에 패킹의 "∩"형 돌출부(6)와 ""형 돌출부(6')를 감삽하여 양측으로 양접관을 밀어넣고 확개 요입부(10)(10')에 철링(11)(11')을 끼워 양측 외측에서 다수의 보울트(12)(12')로 체결토록 하여서 된 것이다.Cross section " The grooves 3, 3 'are formed at regular intervals so as to form a plurality of arc-shaped fusing portions 2, 2' on the inner surface of the packing 1, 1 'which is formed on the circular wheel of the " The indentations 4 and 4 'of the indents are formed longer than the indents 2 and 2', and the outer surfaces of the indents 4 and 4 ' &Quot; ∩ " type locking recesses on both inner sides of the connecting pipe 7, which form a circular protrusion 7 " so as to form a " shaped protrusion 6 " to form a trapezoidal recess 7 " (8) (8 ') and " "∩" shaped protrusions 6 of the packing and the " By inserting the biconvex tube on both sides by subtracting the "shaped projection 6 'and inserting the iron rings 11 and 11' into the expansion recesses 10 and 10 ', a number of bolts 12 and 12' It was made to be tightened with).
도면중 미설명부호(13)(13')는 외주면에 폴리에칠렌층(14)(14')을 형성한 접관하고저 하는 강관이다. 이와 같이 구성된 본 고안의 작용효과를 설명하면 연결관(7)의 내측 양쪽 "∩"형 걸림요입부(8)(8')와 ""형 걸림요입부(9)(9')에 패킹(1)(1')의 "∩"형 돌출부(6)와 ""형 돌출부(6')를 감삽되게 한 다음 연결관(7)의 양쪽으로 접관하고저 하는 강관(13)(13')을 밀어 넣으면 강관(13)(13')의 외주면에 패킹(1)(1')의 내측 융출부(2)(2')(4)(4')가 밀착되므로 강관(13)(13')의 외주면으로 철링(11)(11')을 끼워 철링(11)(11')을 연결관(7)의 양쪽확개요입부(10)(10')에 밀어넣고 그 외측으로 다수의 보울트(12)(12')를 체결하면 보울트(12)(12')의 첨단부가 강관(13)(13')의 외주면으로 적층한 폴리에치렌층(14)(14')을 파고 들어가 양쪽 강관(13)(13')을 고정하여 접관을 하게 된다.In the figure, reference numerals 13 and 13 'are welded and made of steel pipes in which a polyethylene layer 14 and 14' is formed on an outer circumferential surface thereof. Referring to the operation and effect of the present invention configured as described above, both inner " ∩ " type locking recesses 8, 8 'and " &Quot; ∩ " shaped protrusions 6 of the packings 1 and 1 'to the " shaped locking recesses 9 " The steel pipes 13 and 13 'are pushed into the circumferential surface of the steel pipe 13 and 13' by allowing the " -shaped protrusion 6 " Since the inner fusion portions 2, 2 ', 4, and 4' of 1 'are in close contact, the steel rings 11 and 11' are fitted into the outer circumferential surfaces of the steel pipes 13 and 13 '. (11 ') is pushed into both expansion recesses (10) and (10') of the connector (7), and a plurality of bolts (12) (12 ') are fastened to the outside of the bolt (12) (12'). The tip portion penetrates the polyethylene layers 14 and 14 'stacked on the outer circumferential surface of the steel pipes 13 and 13' and fixes both steel pipes 13 and 13 'to be welded.
보수를 하고저 양쪽 강관(13)(13')을 해체할때에는 보울트(12)(12')를 나해하고 양쪽 강관(13)(13')을 외측으로 잡아 당기면 쉽게 해탈된다. 이와 같이 본 고안은 연결관의 내 측 양쪽에 감삽되는 패킹의 고정상태가 견고하여 패킹의 위치가 항상 일정하고 강한 수압이나 외력에도 패킹 자체에 변형을 주지않아 항상 양쪽 접합 강관사이에 밀착되어 있으므로 수밀성과 밀봉효과가 우수하여 강관내부의 유수가 누수될 염려가 없으며 연결 해체 작업을 능률적으로 수행케 하는 실용적인 유용한 고안이다.When dismantling both steel pipes (13, 13 ') after repairing, bolts (12) (12') are released, and both steel pipes (13) (13 ') are pulled out to be easily released. As such, the present invention has a rigid fixed state of the packing which is inserted on both inner sides of the connecting pipe so that the packing position is always constant and does not deform the packing itself even under strong water pressure or external force. It has excellent sealing and sealing effect, so there is no risk of water leakage inside the steel pipe and it is a practical and useful design to make the connection dismantling work efficiently.
