분리조립이 가능한 이중벽하수관 연결장치{Coupling system of double wall drain pipe which is able to seperate and assemble}Coupling system of double wall drain pipe which is able to seperate and assemble}

본 발명은 이중벽하수관의 선단에 일체로 융착된 연결소켓 및 커플러를 이용하여 이중벽하수관을 원터치로 간편하게 조립연결 가능하면서도 선택적으로 연결소켓 및 커플러를 손상 없이 분리하여 다른 이중벽하수관과 재조립 연결하여 사용할 수 있는 이중벽하수관의 연결에 관한 기술분야에 속하는 것이다.The present invention can be easily assembled and connected to the double wall sewer pipe with one touch by using a connection socket and coupler fused integrally to the tip of the double wall sewer pipe, but can be used by reassembling and connecting with other double wall sewer pipes by separating the connection socket and the coupler without damage. It belongs to the technical field related to the connection of double wall sewer pipe.

일반적으로 합성수지재 이중벽하수관은 내부에 하나 또는 여러 개의 중공을 갖도록 프로파일을 성형한 후 냉각과정을 거쳐 와인더에 나선형으로 공급하면서 프로파일의 사이에 용융원료를 공급하여 프로파일을 연속하여 연결시키는 방법으로 성형한다.In general, synthetic double wall sewage pipes are formed by forming a profile to have one or several hollows therein, and then cooling the spirally to the winder while supplying molten raw material between the profiles to connect the profiles continuously. do.

이와 같은 이중벽하수관은 관벽이 내벽과 외벽으로 되고 그 사이에 공간부를 갖는 이중벽구조로 되어 관벽의 수직모멘트를 강화시키고 외압이나 토압 등에 의한 뒤틀림을 최소화시키며, 또한 흄관 및 타관 등에 비해 중량이 가벼워 운반, 취급, 시공이 용이하며, 내약품성 및 내충격성에 강한 특성을 지니고 있어서 각종 오, 폐수 하수관 및 농업용수관 등으로 널리 쓰이고 있다.Such double wall sewer pipe has a double wall structure with inner wall and outer wall and a space between them to reinforce the vertical moment of the wall and minimize the distortion caused by external pressure and earth pressure, etc. It is easy to handle and construct, and has strong characteristics of chemical resistance and impact resistance, so it is widely used for various sewage, wastewater sewage pipes and agricultural water pipes.

이러한 이중벽하수관은 일정한 길이(약 6미터)로 절단하여 보관하게 되며, 땅속에서 다양한 연결방법으로 연결한다.These double wall sewer pipes are cut to a certain length (about 6 meters) and stored and connected by various connection methods in the ground.

A connection socket 10 having a first lock groove 12 into which 30 is partially fitted; A second lock groove 22 is integrally attached to the other end of the double wall sewer pipe 1 so as to be water flowable, and the lock ring 30 is completely received along the circumferential direction or fitted to protrude outward. A coupler 20 formed; When the coupler 20 is inserted into the connection socket 10, the coupler 20 is completely accommodated in the second lock groove 22 and expands at the moment when the second lock groove 22 and the first lock groove 12 coincide with each other. And lock ring 30 having an expansion elasticity is inserted into the first lock groove 12 at the same time while maintaining the binding force; It can be seen that the organic coupling configuration of the plurality of unlocking holes 40 formed in communication with the first lock groove 12 to the outer periphery of the connecting socket 10.

이하, 상기 개략적인 구성으로 이루어진 본 발명을 실시 용이하도록 좀더 상세하게 설명하기로 한다.Hereinafter, the present invention made of the schematic configuration will be described in more detail.

우선적으로 본 발명의 핵심기술구성요소인 연결소켓(10) 및 커플러(20)는 사출성형을 통해 대량으로 양산한 후 이를 공장에서 기존의 이중벽하수관(1)에 열융착을 통해 일체로 부착함으로써 현장에서 즉석으로 상기 연결소켓(10)에 커플러(20)를 삽입하여 원터치로 이중벽하수관(1)을 조립 연결할 수 있게 된다.First of all, the connecting socket 10 and the coupler 20, which are the core technology components of the present invention, are mass-produced through injection molding, and are then integrally attached to the existing double wall sewer pipe 1 through heat fusion at the factory. By inserting the coupler 20 into the connection socket 10 on the fly, the double wall sewer pipe 1 can be assembled and connected with one touch.

이를 위한 연결소켓(10)은 양측으로 관통하는 통수공(11)이 내부에 형성됨에 따라 이중벽하수관(1)의 일측 선단에 통수가능하게 일체로 부착되고, 상기 내주연에는 원주방향을 따라 록크링(30)이 부분적으로 끼워지는 제1 록크홈(12)이 형성된다.The connection socket 10 for this purpose is integrally attached to one end of the double wall sewer pipe 1 as the water supply hole 11 penetrates to both sides is integrally formed, and the lock ring is circumferentially formed on the inner circumference. A first lock groove 12 into which the 30 is partially fitted is formed.

이때 상기 제1 록크홈(12)은 록크링(30)이 부분적으로 끼워지되 록크링(30)의 단면적상 절반이 끼워지도록 반원형의 홈으로 형성됨으로써 나머지 절반 부위는 제2 록크홈(22)에 정확하게 끼워지면서 결속력이 어느 한쪽의 록크홈에 편중되지 않고 균형을 유지하여 더욱 원활한 결속력을 갖는다.At this time, the first lock groove 12 is formed in a semi-circular groove so that the lock ring 30 is partially fitted, but half of the lock ring 30 is fitted into the second lock groove 22. It fits correctly and the binding force is balanced without being biased in one of the lock grooves, so that the binding force is smoother.

상기 이중벽하수관(1)의 타측 선단에 부착되는 커플러(20)는 역시 내부에 통수공(21)이 형성되고, 외주연에는 원주방향을 따라 록크링(30)이 선택적으로 완전하게 수납되거나 또는 외부로 돌출하게 끼워지는 제2 록크홈(22)이 형성된다.Coupler 20 is attached to the other end of the double wall sewer pipe (1) is also formed with a through-hole 21, the outer ring has a lock ring 30 is selectively received or completely along the circumferential direction The second lock groove 22 is formed to be protruded into the.

그리고 상기 연결소켓(10)과 커플러(20)는 팽창탄성을 갖는 록크링(30)에 의해 일체화된 결속력을 유지하면서 이중벽하수관(1)을 원터치로 조립 연결한다.The connecting socket 10 and the coupler 20 are assembled and connected to the double wall sewer pipe 1 by one touch while maintaining the binding force integrated by the lock ring 30 having expansion elasticity.

이와 같은 역할을 수행하는 록크링(30)은 도 3 및 도 4와 같이 연결소켓(10)에 커플러(20)가 삽입되는 과정에서는 작업자가 록크링(30)을 누르면서 조여주면 외부로 돌출되지 않고 제2 록크홈(22)에 완전하게 수납됨으로써 커플러(20)가 연결소켓(10)에 원활하게 끼움 조립될 수 있게 된다.In the process of inserting the coupler 20 into the connection socket 10 as shown in FIGS. 3 and 4, the lock ring 30 performing the role does not protrude to the outside when the operator tightens the lock ring 30. By being completely accommodated in the second lock groove 22, the coupler 20 can be assembled to the connection socket 10 smoothly.

그리고 상기 제1 록크홈(12)이 제2 록크홈(22)에 일치하는 순간에는 도 5 및 도 6과 같이 록크링(30)은 외측으로 자동 팽창하면서 제1 록크홈(12)에 동시에 중첩으로 끼워져 견고한 결속력을 유지함으로써 이중벽하수관(1)을 일체화 조립 연결할 수 있게 된다.When the first lock groove 12 coincides with the second lock groove 22, the lock ring 30 automatically expands to the outside and overlaps the first lock groove 12 at the same time as shown in FIGS. 5 and 6. The double wall sewer pipe (1) can be integrally assembled and connected by maintaining the firm binding force.

여기에서 상기 제2 록크홈(22)은 커플러(20)가 연결소켓(10)에 삽입되는 과정에서 록크링(30)이 외부로 돌출하지 않도록 완전하게 수납될 수 있는 깊이로 형성되되 상기 제2 록크홈(22)에 록크링(30)이 걸림 현상 없이 원활하게 삽입 및 이탈될 수 있도록 상기 제2 록크홈(22)에는 외주연과 접하는 수직안내면(23)이 양측에 형성된다.Here, the second lock groove 22 is formed to a depth that can be completely accommodated so that the lock ring 30 does not protrude to the outside in the process of the coupler 20 is inserted into the connection socket 10, the second The second lock groove 22 is provided with vertical guide surfaces 23 in contact with the outer circumference thereof so that the lock ring 30 can be smoothly inserted into and released from the lock groove 22 without being caught.

또한, 상기 록크링(30)에 의해 일체화된 결속력을 유지하는 연결소켓(10) 및 커플러(20) 간의 연결부위에는 누수를 방지하기 위해 상기 커플러(20)의 외주연에 등간격으로 다수의 링홈(24)이 형성되고, 이 링홈(24)에는 수밀링(25)이 추가로 끼움 설치됨으로써 더욱 확실한 기밀을 유지한다.In addition, a plurality of ring grooves at equal intervals on the outer circumference of the coupler 20 to prevent leakage in the connection portion between the connection socket 10 and the coupler 20 maintaining the binding force integrated by the lock ring 30. (24) is formed, and the water ring (25) is additionally fitted into the ring groove (24) to maintain more sure airtightness.

한편, 본 발명은 상기 이중벽하수관(1)이 기본 설계도에 맞추어 정확하게 시 공이 제대로 이루어지지 않은 경우, 또는 시공 후에 유지보수가 필요한 경우에 이중벽하수관(1)을 손상 없이 신속하고 간편하게 분리하기 위한 언록킹홀(40)이 연결소켓(10)의 외주연에 방사상으로 제1 록크홈(12)과 외부로 연통하게 형성된다.On the other hand, the present invention, the double wall sewage pipe (1) is unlocked to quickly and easily separate the double wall sewage pipe (1) without damage when the construction is not correctly made according to the basic design, or when maintenance is required after construction The hole 40 is radially formed on the outer circumference of the connecting socket 10 so as to communicate with the first lock groove 12 to the outside.

따라서, 별도의 누름구(47)를 도 8과 같이 상기 언록킹홀(40)에 삽입하여 록크링(30)을 내향으로 눌러주면 상기 록크링(30)이 제1 록크홈(12)을 이탈하면서 결속력이 일시적으로 해제됨으로써 커플러(20)를 간편하게 분리하여 이중벽하수관(1)의 손상을 방지하며, 이에 따라 분리된 이중벽하수관(1)을 재조립 연결하여 사용할 수 있는 효과를 제공한다.Therefore, when the separate pressing hole 47 is inserted into the unlocking hole 40 as shown in FIG. 8 and the lock ring 30 is pressed inward, the lock ring 30 is separated from the first lock groove 12. While the binding force is temporarily released, the coupler 20 is easily separated to prevent damage to the double wall sewer pipe 1, thereby providing an effect of reassembling and connecting the separated double wall sewer pipe 1.

아울러 본 발명은 도 9 내지 도 12와 같이 스냅링(300)이 연결소켓(100)에 일체화 결합된 다른 형태로 실시될 수 있게 된다.In addition, the present invention can be implemented in another form in which the snap ring 300 is integrally coupled to the connection socket 100 as shown in FIGS.

상기 다른 실시예의 연결소켓(100)은 이중벽하수관(1)의 일측 선단에 통수가능하게 일체로 부착되고, 내주연에는 원주방향을 따라 스냅링(300)이 선택적으로 완전하게 수납되거나 또는 내부로 돌출하게 끼워지는 제1 록크홈(102)이 형성된다.The connection socket 100 of the other embodiment is integrally attached to one end of the double wall sewer pipe (1), and the snap ring 300 in the circumferential direction is selectively completely accommodated or protrudes in the inner circumferential direction The first lock groove 102 to be fitted is formed.

또한, 상기 이중벽하수관(1)의 타측 선단에 통수가능하게 일체로 부착되는 커플러(200)는 외주연에 원주방향을 따라 스냅링(300)이 부분적으로 끼워지는 제2 록크홈(202)이 형성된다.In addition, the coupler 200, which is integrally attached to the other end of the double wall sewer pipe 1, is integrally formed with a second lock groove 202 in which the snap ring 300 is partially fitted along the circumferential direction. .

그리고 상기 제1, 제2 록크홈(102)(202)에 동시에 중첩으로 끼워지면서 결속력을 유지하는 팽창탄성을 갖는 스냅링(300)은 상기 연결소켓(100)에 커플러(200)가 삽입되는 과정에서는 제1 록크홈(102)에 완전하게 수납되면서도 상기 제1 록크 홈(102)과 제2 록크홈(202)이 일치한 상태에서 작업자가 일측의 걸림편(301)을 연결소켓(100)에 형성된 고정홀(105)에 고정상태로 끼움 결합된 타측 걸림편(301a)의 방향으로 이동홈(106)을 따라 이동시키면 내향으로 수축하면서 제2 록크홈(202)에 동시에 중첩으로 끼워져 결속력을 유지한다.In addition, the snap ring 300 having an expansion elasticity that maintains the binding force while being inserted into the first and second lock grooves 102 and 202 at the same time is overlapped in the process of inserting the coupler 200 into the connection socket 100. While completely accommodated in the first lock groove 102, the operator forms the engaging piece 301 on one side of the connection socket 100 while the first lock groove 102 and the second lock groove 202 coincide with each other. When moving along the moving groove 106 in the direction of the other locking piece 301a coupled to the fixing hole 105 in a fixed state, it is contracted inward and is simultaneously overlapped with the second lock groove 202 to maintain the binding force. .

이때 이동홈(106)을 따라 이동하는 걸림편(301)은 이동홈(106)의 내면에 돌출 형성된 걸림턱(107)에 선택적으로 걸리면서 이동이 제한됨으로써 록킹을 유지한다.At this time, the locking piece 301 moving along the moving groove 106 is selectively caught by the locking jaw 107 protruding from the inner surface of the moving groove 106, thereby maintaining the locking.

그리고 상기 조립 연결상태의 커플러(200)를 분리하기 위해서는 도 10 및 도 11과 같이 걸림턱(107)에 걸려있는 걸림편(301)을 이동홈(106)을 따라 외향으로 이동시키면 록킹이 해제됨과 동시에 스냅링(300)이 도 12와 같이 팽창하면서 제2 록크홈(202)을 이탈하면서 결속력이 일시적으로 해제됨으로써 커플러(200)를 간편하게 분리하면서도 이중벽하수관(1)의 손상을 방지한다. In addition, in order to separate the coupler 200 in the assembled and connected state, as shown in FIGS. 10 and 11, when the locking piece 301 hanging on the locking step 107 is moved outward along the moving groove 106, the locking is released. At the same time, as the snap ring 300 expands as shown in FIG. 12, the binding force is temporarily released while leaving the second lock groove 202, thereby easily removing the coupler 200 and preventing damage to the double wall sewer pipe 1.
