본 고안은 외주면에 돌출부와 요입부를 나선형으로 형성한 나선파형관을 접속하는 합성수지제 접속구에 관한 것이다.The present invention relates to a synthetic resin connector for connecting a spiral wave tube formed in a spiral shape on the outer circumferential surface.
종래에는 돌출부를 나선형으로 요철되게 형성한 나선파형관의 외주면과 거의 동일한 형상 및 크기의 나선파형을 내주면에 형성한 원통형 카우스(접합구)에 양단부에 상기 나선파형관을 회전시켜 끼워넣어서 생긴 양 요철파형의 틈새에 발포수지등의 충진재를 충진하여 되는 관접속구조 및 방법이 특허공고 제93-2536호로 제안되었으나, 이 카우스의 양단에 나선파형관을 회전시켜 체결하기가 용이한 반면 그 충진재는 비교적 고가이고, 충진작업은 이동식 충진설비 및 기구 등을 이용하여야 하는 것이므로, 이 작업수행에는 그 충진설비 및 숙련된 인력이 동원되어야 하기 때문에 관 매설비용을 크게 증가시키는 것이어서 실용화되지 못하고 있는 것이다.Conventionally, both of the uneven waveforms formed by rotating the spiral wave tube at both ends are inserted into a cylindrical cowl (joint) formed on the inner circumferential surface of a spiral wave of approximately the same shape and size as the outer circumferential surface of the spiral wave tube having the protrusions spirally unevenly formed. Although the connection structure and method for filling a filler such as foamed resin in the gap was proposed in Korean Patent Publication No. 93-2536, it is easy to fasten the spiral wave tube at both ends of the cow, while the filler is relatively expensive. Since the filling operation requires the use of mobile filling facilities and apparatuses, the filling operation and skilled manpower must be mobilized to perform this operation, which greatly increases the use of the irrigation equipment and thus is not practical.
또, 외주면에 돌출부와 요입부를 나선형으로 형성한 나선파형관의 합성수지제 접속구로서, 양측에 설치한 결속편을 체결할 때 양 결속편 사이에 "Y" 자형의 패킹을 끼우고 볼트로 체결되는 체결구가 실용신안공고 제93-6055호로 제안되어 있으나, 이 제안에 의하면 그 접속구조는 접속하고자 하는 양 나선파형관의 외주면을 감싸주는 접속부의 내면이 평면이므로, 나선파형관의 요입부에 발포물질등으로 몰딩하여 패킹처리하여야 한다는 것이다. 이 제안에서 발포물질등의 몰딩으로 패킹을 형성한다는 것은 궁극적으로 누수방지층을 형성하기 위한 것이므로, 이 패킹의 형성없이는 고안의 목적을 기대할 수 없는 것이다.In addition, it is a synthetic resin splicing connector of a spiral wave tube formed by spirally forming protrusions and concave portions on the outer circumferential surface. When fastening the binding pieces installed on both sides, the fastener is fastened with bolts by inserting a "Y" shaped packing between the two binding pieces. Is proposed in Korean Utility Model Publication No. 93-6055. However, according to this proposal, since the inner surface of the connecting portion covering the outer circumferential surface of both spiral wave tubes to be connected is flat, molded parts of the spiral wave tube with foam material or the like Is to be packed. In this proposal, since the packing is formed by molding of a foam material or the like, it is ultimately to form a leakage preventing layer, and thus the purpose of the design cannot be expected without the formation of the packing.
그리나, 상기의 발포물질등을 몰딩하여 패킹처리한다는 것은 발포물질이 비교적 그 가격이 고가이고, 그 작업에 적합한 새로운 몰딩 설비 및 숙련된 조작 인력이 동원되어야 하기 때문에 관 연결비용을 크게 증가시키는 것이어서 지금까지 실용화되지 못하고 있는 것이다.However, molding and packing the above-mentioned foamed material, etc., is a relatively high price of foamed material, and a new molding facility and skilled manpower required for the operation are required to greatly increase the pipe connection cost. It has not been put to practical use.
또한, 종래에 각종 관체의 접속 연결구조는 그 관체의 재질 및 용도에 따라 이에 상응하게 소켓, 플랜지, 분할식 접속구등으로 접속하여 왔으나, 분할식 접속구는 비교적 그 사용이 간편하다는 점에서 더욱 선호하여 온 것이다.In addition, the connection structure of various pipes in the past has been connected with sockets, flanges, split joints, etc. according to the material and use of the pipes, but the split joints are more preferred in that they are relatively easy to use. Came.
그러나 접속 연결하고자 하는 관이 합성수지제 나선파형관일 때 철재로 되는 분할식 접속구를 사용하면 합성수지관보다 먼저 산화부식되어 관 접속의 체결력을 상실하게 되어 그 접속을 유지할 수 없게 되는 것이다.However, if the pipe to be connected is a spiral spiral pipe made of synthetic resin, the use of a split joint made of steel oxidizes and corrodes the synthetic resin pipe, leading to loss of the clamping force of the pipe connection, and thus the connection cannot be maintained.
본 고안자는 상기 문제점등을 해결하기 위하여 합성수지제 나선파형관과 같은 합성수지재로 비교적 그 체결이 간편한 종래에 철재로 되는 분할식 접속구와 같이 반원형 접속판과 플랜지부의 두께를 동일하게 성형하여 시험해 본 바, 제4도에서와 같이 접속구의 반원형 접속판(02)과 같은 두께(h)로 플랜지부(03)의 두께(h)를 형성한 경우 양 플랜지부(03)(03)를 볼트로 체결하였을 때, 그 패킹전체가 균일하게 압착되지 않아 사이가 벌어져서 누수를 방지할 수 없었다. 그 이유는 접속하는 양 나선파형관을 이어놓고 그 요입부 및 돌출부에 착설한 패킹을 압착하여 누수를 방지할 수 있는 정도의 반원형 접속판(02) 체결력을 지탱하지 못하기 때문인 것을 알게되어 시험을 계속한 결과 플랜지부(03)의 두께를 반원형 접속판 두께(h)의 2배이상으로 하였을때에 비로소 양 플랜지부(03)(03)를 체결한 사이가 벌어지지 않고 패킹전체는 균일하게 압착되어 완전하게 누수방지층이 형성되는 것을 알게 되었다.The present inventors molded and tested the same thickness of the semi-circular connecting plate and the flange portion as the conventional split type connector made of steel, which is relatively easy to fasten with synthetic resin material such as synthetic resin spiral wave tube. When the thickness h of the flange portion 03 is formed to the same thickness h as the semicircular connecting plate 02 of the connector as shown in FIG. 4, both flange portions 03 and 03 may be bolted together. At that time, the whole packing was not uniformly compressed and the gap was widened to prevent water leakage. It was found that the reason was that the semi-circular connecting plate (02) was not able to support the fastening force of the semicircular connecting plate (02) to prevent leakage by connecting the spiral wave pipes connected to each other and squeezing the packing installed on the recess and protrusion. As a result, when the thickness of the flange portion 03 is more than twice the thickness of the semicircular connecting plate h, the entire packing is not evenly spaced between the two flange portions 03 and 03. It was found that the leakproof layer was completely formed.
본 고안은 나선파형관의 분할식 접속구를 합성수지재로 성형함에 있어서, 반원형 접속판 두께(h)의 약 2배이상으로 한 플랜지부의 두께(H)를 형성하여 되는 것을 특징으로하는 것으로서, 이를 첨부도면에 의하여 설명한다.The present invention is characterized in that when forming the split joint of a spiral wave tube with a synthetic resin material, the thickness (H) of the flange portion which is at least about twice the thickness (h) of the semicircular connecting plate is formed. It demonstrates with drawing.
제1도는 본 고안 합성수지제 접속구(1)의 분해 사시도로서, 반원형 접속판(2)의 양측연에 그 체결력을 지탱할 수 있는 4각형동체 플랜지부(3)(4)를 일체로 형성함에 있어서, 상기 플랜지부(3)(4)의 두께(H)를 적어도 접속판(2) 두께(h)의 약 2배이상으로 하는 것을 특징으로 하는 합성수지제 접속구이다.1 is an exploded perspective view of the connector 1 made of synthetic resin of the present invention, in which the quadrilateral fuselage flange portions 3 and 4 are integrally formed on both side edges of the semicircular connecting plate 2 to support the fastening force. The thickness H of the flange portions 3 and 4 is at least about twice the thickness h of the connecting plate 2, and is a synthetic resin connecting port.
첨부도면중 미설명부호 5는 플랜지부(3)(4)에 일정한 간격으로 뚫은 볼트의 체결구멍이며, 6 및 6a는 접속관, 7 및 7a는 패킹을 각각 표시하는 것이다.In the accompanying drawings, reference numeral 5 denotes fastening holes of bolts drilled at regular intervals in the flanges 3 and 4, 6 and 6a denote connection tubes, and 7 and 7a denote packings, respectively.
본 고안의 실시에 있어서, 플랜지부(3)(4)는 제1도 내지 제3도에서와 같이 접속판(2) 두께(h)의 약 2배이상의 두께(H)로 접속판(2)의 양쪽연부에 일체로 형성시켜서 되는 것이며, 제2도에서 보는 바와 같이 접속판(2)의 양측연부에 일체로 형성시킨 플랜지부(3)(4)중 일측 플랜지부(3)의 내측단에 경사밀착편(3b)을 일체로 돌설시키고, 타측 플랜지부(4)의 내측단에는 상기 경사밀착편(3b)이 들어가 끼워지는 경사부(4b)를 형성하여 한쌍의 접속구(1)(1)을 대향시켜 체결하였을때 경사밀착편(3b)은 경사부(4b)내에 들어가 끼워져서 밀착되어 접속판(2)의 밀착효과를 증대시켜 더욱 면밀한 압착상태로 패킹(7)(7a)을 압착 유지하도록 하는 것이다.In the practice of the present invention, the flange portion (3) (4) is the connecting plate (2) to a thickness (H) of about twice or more than the thickness (h) of the connecting plate (2) as shown in Figs. Of the flanges 3, 4 formed integrally at both edges of the connecting plate 2, as shown in FIG. The inclined contact piece 3b is integrally protruded, and the inclined part 4b into which the inclined contact piece 3b is inserted is formed at the inner end of the other flange portion 4 so as to have a pair of connection ports 1 and 1. Is pressed against each other, the inclined contact piece 3b is inserted into the inclined part 4b to be in close contact, thereby increasing the contact effect of the connecting plate 2, and pressing and holding the packings 7 and 7a in a more precise crimped state. To do that.
본 고안은 제3도에 도시하고 있는 것과 같이 접속하고자 하는 나선파형관(6)(6a)의 요입부에 들어가 끼워지는 패킹(7a)과 그 외주를 감싸주는 패킹(7)을 각각 착설한 다음 한쌍의 접속구(1)(1)를 체결하므로서 상기의 패킹(7)(7a)을 균일하게 압착하여 누수를 방지하게 되는 것입니다.In the present invention, as shown in FIG. 3, a pair of packings (7a) inserted into the recessed portions of the spiral wave tube (6) (6a) to be connected and a packing (7) surrounding the outer periphery are respectively installed, By tightening the connection ports (1) and (1) of the fitting, the packing (7) and (7a) above are uniformly crimped to prevent leakage.
본 고안은 이상에서 상술한 바와 같이 합성수지제 접속구(1)로서 반원형 접속판(2)에 가해지는 그 체결력을 지탱할 수 있게 4각형동체의 플랜지부(3)(4)를 일체로 형성한 것으로서 그 제작 및 시공이 간편하고, 그 체결상태가 견고할 뿐만아니라 지구력이 우수한 합성수지제 접속구를 염가로 제공하는 것이다.The present invention, as described above, is formed by integrally forming the flange portion (3) (4) of the quadrilateral body to support the fastening force applied to the semi-circular connecting plate (2) as a synthetic resin connector (1) It is easy to manufacture and construct, and the connection state is firm and the endurance is excellent in endurance.
