주철관의 접합장치Joining device of cast iron pipe

제1도는 본 고안의 요부를 전개한 일부 절제 사시도.1 is a partially cutaway perspective view of the main part of the present invention.

제2도는 본 고안과 종래의 타이튼 죠인트식 주철관의 체결 상태를 대비한 도면으로서, 2a도는 본 고안의 단면도, 2b도는 종래의 단면도.2 is a view for preparing the fastening state of the present invention and the conventional Titanium joint type cast iron pipe, 2a is a cross-sectional view of the present invention, 2b is a conventional cross-sectional view.

본 고안은 타이튼 죠인트식 주철관의 수구부(受口部)에 착설되는 패킹링의 감착을 위한 접합장치의 개량에 관한 것이다.The present invention relates to the improvement of the joining device for the attachment of the packing ring installed in the water port of the Titanium joint type cast iron pipe.

종래의 타이튼 죠인튼식 주철관(한국 특허 제795호)의 수구부는 제2b도에서와 같이 타이튼식 패킹링의 감착부가 들어가 물리는 직입 요구부의 내측단턱에 호형동출제(弧形突出堤)를 설치하여 끼워진 패킹링이 삽관 작업시에는 밀려나지 않게하고 있는 것이 특징이다. 그러나 좁고 낮은 직업요구부와 그 내측에 설한 얇은 호형 돌출제는 비교적 단면적이 작게 되는 것이므로, 주조(鑄造)시 비중이 작은 주철분순물이 몰려서 기대되는 돌출제가 형성되지 않아 불량품으로 버리거나, 용융주철이 몰리는 힘에 의하여 돌출제를 형성하는 주조형의 요입 부위가 봉괴되어 돌출제가 변형주조되면 그것을 수정하여야 하는 번거러움으로 제작 능률을 크게 저해할 뿐안 아니라, 특히 좁고 낮은 직입 요입부와 연설되는 돌출제의 불완전한 형성은 주철관의 삽관 작업시 패킹링의 착설이 불안전하여 연설삽관작업(延設揷管作業)의 능률을 저해하는 것이다. 또한 그 돌출제가 정확하게 형성된 경우라 할지라도 관을 매설하기 위하여 파놓은 좁은 지하에서 주철관의 수구부에다 착설한 패킹이 밀려나지 않게 삽관부(관말구)를 패킹의 내경에 맞추어 갖다대고 인장용 자크로 삽관을 수구부쪽으로 인장하여The water port of the conventional Titon joinon cast iron pipe (Korean Patent No. 795) is provided with an arc-shaped co-extrusion agent on the inner end of the indentation portion where the fitting portion of the Titon-type packing ring enters and bites as shown in FIG. It is characterized in that the inserted packing ring is not pushed out during intubation. However, the narrow and low job demands and the thin arc-shaped protrusions installed inside them have a relatively small cross-sectional area. Therefore, cast irons with small specific gravity are concentrated during casting, so that the expected protruding agents are not formed. The indentation part of the casting type that forms the protruding force by the driving force is closed and the protrusion is deformed and cast, which not only impedes the production efficiency greatly, but also the narrow and low indentation indentation and the incomplete protrusion of the protruding part. Formation is an unstable installation of the packing ring during intubation of cast iron pipe, which hinders the efficiency of speech intubation. Also, even if the protruding agent is formed correctly, the intubation part is placed in accordance with the inner diameter of the packing so that the packing placed in the narrow part of the cast iron pipe is not pushed out in the narrow underground where the pipe is buried. By pulling the intubation towards the water port

본 고안은 상기한 바와 같은 종래이 타이튼 죠인트식 주철관의 문제점을 해소하기 위하여 제안되는 것으로, 예시도면에 의하여 상세히 설명하면 다음과 같은 것이다.The present invention is proposed in order to solve the problem of the conventional Titanium joint type cast iron pipe as described above, will be described in detail by the following drawings.

본 고안은 제1도에서 보는 바와 같이 주철관(1)의 수구부(2) 내주면 후단부의 삽관부(3)보다 깊게 연설된 종래의 패킹 압착부(4)에다 타이튼 죠인트식 패킹링(a)의 종래의 감착부보다 높게 형성한 감착부(a')를 감착함에 있어서, 상기 패킹압착부(4)의 선단에 상기 패킹감착부(a1)가 걸리는 걸턱(5)을 요입륜부(6)의 외주연에 설한 접합후랜지(7)를 형성하고, 그 후랜지(7)와 동일폭의 접합면(8)을 가지는 외주연에 압착돌륜(9)을 돌설한 그 접합면(8)의 하측연장부(8a)에 절결구(8b)를 설한 체결링(10)에 의하여 체결되는 주철관의 접합장치인 것이다. 도면중 미설명부호 11은 체결공, 12는 체결보울트, 13은 삽관, 13a는 삽관의 돌턱을 표시하는 것이며, 도시하고 있는 패킹(a)의 감착부(a1)는 본 고안의 접합 장치에 착설됨을 요건으로 하는 것이다.The present invention, as shown in FIG. 1, is a Titanium joint packing ring (a) in the conventional packing crimping portion 4, which is deeper than the intubation portion 3 of the rear end surface of the inner circumferential surface of the water pipe portion 2 of the cast iron pipe 1. In the desorption of the desorption part a 'formed higher than the conventional desorption part of the present invention, the jaw 5 in which the packing desorption part a 1 is applied to the tip of the packing desorption part 4 is recessed wheel part 6. Joining flanges (7) formed on the outer periphery of the head), and the joining surfaces (8) protruding the pressing projection wheel (9) on the outer periphery having a joining surface (8) of the same width as the flange (7). It is a joining device of the cast iron pipe which is fastened by the fastening ring 10 is installed in the lower extension portion (8a) of the cutout (8b). In the drawings, reference numeral 11 denotes a fastening hole, 12 a fastening bolt, 13 an intubation, and 13a an incidence of the intubation, and the fitting portion (a 1 ) of the packing (a) shown in FIG. It is required to be installed.

본 고안은 주철관(1) 수구부(2)의 선단부 내주면을 삭설한 요입륜부(6)내에 타이튼 죠인트식 패킹링(a)의 감착부(a1)가 들어가 걸턱(5)에 걸리게 착설한 다음 체결링(10)의 접합면(8)을 접합후랜지(7)에 갖다대고 양측체결공(11)에 보울트(12)를 체결시키면 체결링(10)의 돌륜(9)의 압착으로 패킹(a)의 감착부(a1)는 걸턱(5)에 견고하게 결착되는 것이다. 설명한 바와 같이 주철관의 제조공장 또는 매설현장의 지상에서 미리 패킹(a)를 체결한 것을 매설하기 위해 파놓은 지하에다 들어넣고, 미리 체결된 패킹(a)에 삽관(13)을 갖다대고 인장용 자크로 삽관작업을 시According to the present invention, the fitting portion (a 1 ) of the Tighten joint type packing ring (a) is inserted into the recess (6) in which the inner circumferential surface of the distal end portion of the cast iron pipe (1) and the fitting portion (2) is inserted into the hook (5). Next, the joint surface 8 of the coupling ring 10 is brought to the joint flange 7 and the bolts 12 are fastened to both side fastening holes 11 so as to be compressed by the compression of the protrusions 9 of the coupling ring 10. The fitting part (a 1 ) of (a) is to be firmly bound to the step (5). As described above, in the manufacturing plant of the cast iron pipe or in the buried site, the plunger is placed in the basement to be buried, and the insulated pipe (13) is placed in the prepacked packing (a). During intubation

여기에서의 삽관돌턱(13a)에 관한 설명은 실시의 예시로서, 본 고안의 등록청구의 범위를 제한하는 것이 아니다.Description of the intubation step 13a here is an example of implementation, and does not limit the scope of the registration request of the present invention.

본 고안은 제2a도도에서와 같이 패킹(a)의 압착부(a2)가 삽관(13)의 압입으로 신장되면서 강력히 압착되어 면밀하고 강력한 수밀압력을 가지게 견고히 체결되는 것이며, 유사시에 매설관을 해체하고저 할 때에는 그 체결보울트(12)를 해체하는 것으로 용이하게 삽관을 인출할 수 있게 되는 것이다. 따라서 2b도에서와 같은 종래의 패킹 감착을 위한 돌출제의 형성에 따르는 주철관 주조상의 문제점 및 삽관 작업상의 문제점이 완전히 해소되는 것이다.The present invention, as shown in Figure 2a is a pressing portion (a 2 ) of the packing (a) is extended by the press-fitting of the intubation tube 13 is pressed firmly to have a tight and tight watertight pressure tightly, in case of buried pipe When dismantling, the intubation can be easily taken out by disassembling the fastening bolt 12. Therefore, the problem of casting of the cast iron pipe and the problem of intubation due to the formation of the protrusion for the conventional packing fitting as shown in FIG. 2b is completely solved.

또한 본 고안의 목적하는 바 지하에서의 주철관 부설 또는 해체작업상의 까다로움과 불편에 따르는 모든 낭비를 일소할 수 있는 실용적인 효과 뿐만아니라, 종래에 매설되는 장소보다 좁게 파내도 되는 공사비용의 절감 효과를 제공하는 것이다.In addition, the purpose of the present invention is not only a practical effect that can eliminate all the waste caused by the difficulty and inconvenience of laying cast iron pipes or dismantling work in the basement, but also to reduce the construction cost that can be dug narrower than a conventionally buried place. To provide.
