Description

주하수관과 분기하수관의 연결부재Connecting member of main sewer pipe and branch sewer pipe

본 발명은 주하수관과 분기하수관의 연결부재에 관한 것으로 특히, 주하수관에 분기하수관을 연결하는 연결부재의 설치가 간편하면서 그 연결상태가 견고하고, 기밀성이 양호하여 누수가 되지 않도록 함을 목적으로 한다.The present invention relates to a connection member between the main sewage pipe and the branch sewer pipe, and in particular, the installation of the connection member for connecting the branch sewer pipe to the main sewage pipe is simple and its connection state is solid, and the airtightness is good to prevent leakage. do.

일반적으로 사용되는 하수관은 콘크리트관 또는 합성수지관을 주로 사용하고 있으며, 이중 합성수지관은 외부에 보강리브가 형성된 2 중관체로 제작되므로 내구성과 시공작업성이 우수하기 때문에 근래에 들어 많이 사용되고 있다.Sewage pipes are generally used concrete pipes or synthetic resin pipes, double synthetic resin pipes are made of double pipes with reinforced ribs on the outside, so they have been used in recent years because of excellent durability and workability.

한편, 상기한 바와 같은 종래의 주하수관에는 가정이나 공장 등에서 버려지는 폐수의 배수를 위한 다수의 분기하수관이 연결되는데 이때 적당한 연결부재가 없으므로 종래에는 주하수관에 연결구멍을 뚫고 이에 길이가 짧은 연결관체를 끼운 다음 그 둘레에 접착제 또는 시멘트 몰탈을 덮어 씌워 접착한 후 이에 분기하수관을 연결하고 있다.On the other hand, the conventional main sewage pipes as described above are connected to a plurality of branch sewer pipes for drainage of waste water discarded in homes or factories. After inserting and glued around with adhesive or cement mortar around it, the branch sewer pipe is connected to it.

이와 같이 주하수관에 연결된 분기하수관들은 도로에 매설되므로 차량의 하중충격과 주행진동을 지속적으로 받거나 해동시 지각변동에 의하여 주하수관과의 연결부가 떨어져 누수현상이 일어나면서 지하수오염을 일으키게 되거나, 역으로 주하수관내부로 토사가 유입되어 하수관이 막히게 하는 등의 문제점이 있었다.Since the branch sewer pipes connected to the main sewer pipes are buried on the road, they are continuously subjected to load shocks and driving vibrations of the vehicle, or the groundwater pollution is caused by leakage of the connection with the main sewer pipes due to the earthquake change during thawing. There was a problem such as the sediment inflow into the main sewer pipe to block the sewer pipe.

따라서, 주하수관과 분기하수관의 연결에는 연결작업이 용이하면서 견고하고 누수가 일어나지 않는 연결부재가 요구된다.Therefore, the connection between the main sewage pipe and the branch sewer pipe requires a connection member that is easy to connect and is robust and does not leak.

본 발명은 이상과 같은 필요성에 적합한 연결부재를 제공하기 위하여 강제로 그 부피를 수축시킬 수 있고, 하단에 가변 걸림턱이 구비된 고정단관체를 주하수관에 천공한 분기구멍에 끼워 넣은 후 소켓부가 구비된 연결관체를 상기 고정단관체 내부에 삽입시키면 가변걸림턱이 외향으로 벌어지면서 분기구멍의 내주연턱에 걸려 견고하여 기밀성이 우수하게 고정되도록 구성한 것이다.The present invention can forcibly shrink its volume in order to provide a connection member suitable for such a necessity, the socket portion after inserting a fixed end pipe body having a variable locking jaw at the bottom into a branch hole drilled in the main sewer pipe When the provided connecting pipe is inserted into the fixed end pipe, the variable locking jaw opens outwardly and is secured to be tightly secured to the inner peripheral jaw of the branch hole.

본 발명 예시를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 제1도의 분해 사시도와 같이 통상의 주하수관(100)에 뚫어 설치한 분기구멍(101)에 끼워 고정되는 고정단관체(10)는 강제로 수축시켜 부피(외경)를 축소시킬 수 있는 신축성 재질(고무, 우레탄 등)로 형성하고, 통상의 분기하수관(200)이 끼워 연결되는 연결관체(20)와 상기 연결관체(20)의 이탈 방지를 위하여 고정단관체(10)의 외주연을 압박하는 통상의 결박 밴드(40)로 결합 구성하되, 상기 고정단관체(10)는 하위에 분기구멍(101)의 상주연에 접하는 고정받침턱(11)을 구비하며, 하단에는 내측으로 경사지게 가변걸림턱(12)을 구비하여 상기 고정받침턱(11)과 가변걸림턱(12) 사이에 하수관 삽지홈(13)이 형성되도록 한 것으로 분기구멍(101)에 삽입시에는 제4도와 같이 부피(외경)을 수축시켜 끼우도록 한 것이다.According to the present invention, as shown in the exploded perspective view of FIG. 1, the fixed end pipe body 10 fixed to the branch hole 101 installed and drilled in the general main sewer pipe 100 can be forcibly contracted to reduce the volume (outer diameter). It is formed of an elastic material (rubber, urethane, etc.), and the outer periphery of the fixed end pipe body (10) to prevent the separation of the connecting pipe body 20 and the connecting pipe body 20 is fitted into a conventional branch sewer pipe 200 Composed and configured by pressing the normal strap band 40, the fixed end pipe body 10 has a fixed support jaw (11) in contact with the upper circumference of the branch hole 101 in the lower, variable at an inclined inward A sewage pipe insertion groove 13 is formed between the fixed support jaw 11 and the variable catching jaw 12 by having a catching jaw 12, and when inserted into the branch hole 101, the volume ( The outer diameter) to shrink.

그리고, 연결관체(20)는 상부에 분기하수관(200)이 끼워 연결되는 소켓부(21)를 구비하며, 하부는 고정단관체(10)의 내경에 꼭 맞게 끼워지는 삽착관부(22)로 형성하여 제2도의 착용상태와 같이 삽착관부(22)를 고정단관체(10)의 내부에 끼워주면 그 하단이 가변걸림턱(12)의 내측경사면(12A)을 밀어 가변걸림턱(12)이 외측으로 밀려나도록 함으로서 제3도의 착용된 상태와 같이 가변걸림턱(12)의 외측상면(12B)이 고정받침턱(11)쪽으로 이동하면서 하수관 삽지홈(13)을 좁혀 그 사이에 끼워진 주하수관(100)의 단면(102)을 압박하여 견고하게 결착되면서 기밀성을 유지하게 한다.And, the connecting pipe 20 has a socket portion 21 is inserted into the branch sewer pipe 200 is connected to the upper portion, the lower portion is formed of the insertion pipe portion 22 that fits snugly to the inner diameter of the fixed end pipe body (10) 2, the lower end pushes the inner inclined surface 12A of the variable locking jaw 12 so that the variable locking jaw 12 is outside as shown in FIG. As shown in the worn state of FIG. The cross section 102 of the) is pressed firmly to maintain the airtightness.

본 발명 실시에 있어서, 가변걸림턱(12)외부의 꺽임부에는 홈(14)을 형성하여 가변성이 양호하도록 하며, 가변걸림턱(12) 내부에는 보강철편(30)을 매입시켜 가변걸림턱(12)이 견고하도록 보강할 수 있다.In the practice of the present invention, the grooves 14 are formed in the bent portion outside the variable catching jaw 12 so that the variability is good, and the variable catching jaw 12 is embedded with a reinforcing iron piece 30 inside the variable catching jaw ( 12) can be reinforced to be firm.

이상과 같은 본 발명 연결부재의 착용은 다음과 같다.Wearing the connection member of the present invention as described above is as follows.

고정단관체(10)는 제4도와 같이 강제로 압박하여 부피를 수축시킨다.The fixed end tube 10 is forcibly pressed to shrink the volume as shown in FIG.

특히, 하부의 가변 걸림턱(12)의 외경이 축소되게 수축시켜 주하수관(100)에 뚫려있는 분기구멍(101)에 가변걸림턱(12)부분을 끼워준 후 압박상태를 풀어주면 자체탄성에 의해 원상태로 복귀되어 가변걸림턱(12)은 분기구멍(101)의 내부에서 확대된 상태로 걸려있게 되는 것이다.In particular, the outer diameter of the lower variable locking jaw (12) is reduced to shrink to fit the variable locking jaw (12) to the branch hole 101 drilled in the main sewer pipe 100, and then release the pressure state by the self-elasticity The variable catching jaw 12 is returned to its original state and is caught in an enlarged state inside the branch hole 101.

이와 같은 상태에서 고정단관체(10)내부에 연결관체(20)의 삽착관부(22)를 끼워주면 그 하단부가 가변걸림턱(12)의 내측경사면(12A)을 외측으로 밀어내고 이에 따라 외측상면(12B)이 하수관 삽지홈(13)을 좁혀주게 되므로 결국 주하수관(100)의 하수관 삽지홈(13)에 끼워져 있는 분기구멍(101)의 외주단면(102) 부분이 압박된 상태로 견고하게 결착되는 것이다.In such a state, when the insertion pipe part 22 of the connecting pipe body 20 is inserted into the fixed end pipe body 10, the lower end portion pushes the inner inclined surface 12A of the variable locking jaw 12 outward and thus the outer upper surface. 12B narrows the sewer pipe insertion groove 13, so that the outer peripheral cross section 102 of the branch hole 101, which is inserted into the sewer pipe insertion groove 13 of the main sewer pipe 100, is firmly bound in a pressed state. Will be.

결착후 고정단관체(10)외부에는 통상의 결박 밴드(40)를 묶어 연결관체(20)의 이탈을 방지하므로서 본 발명의 설치가 완료되는 것이다.After the binding, the fixed end pipe 10 is tied to the usual strap band 40 to prevent the detachment of the connecting pipe 20 to complete the installation of the present invention.

이상과 같이 착용되는 본 발명 연결부재는 고정단관체(10)와 연결관체(20)로 구성된 것이어서 그 구성이 간단하고, 그 착용방법은 고정단관체(10)를 수축시켜 분기구멍에 끼운 후 고정단관체(10) 내부에 연결관체(20)를 끼워 결착하는 단순작업이기 때문에 그 설치작업이 간편하고, 설치된 연결부재는 고정단관체(10) 하단의 가변걸림턱(12)이 강제로 외향 이동하여 하수관 삽지홈(13)에 끼워진 하수관의 단면을 압박하면서 체결된 것이므로 그 체결상태가 견고하고 기밀성이 우수하여 누수가 방지되는 효과가 있다.The connection member of the present invention worn as described above is composed of a fixed end pipe body 10 and a connection pipe body 20, the configuration thereof is simple, and the wearing method is fixed after the fixed end pipe body 10 is contracted and inserted into a branch hole. Since the installation work is simple because the fitting pipe 20 is fitted into the short pipe body 10, the installation work is simple, and the variable locking jaw 12 at the lower end of the fixed pipe body 10 is forcibly moved outward. Since it is fastened while pressing the end surface of the sewer pipe inserted into the sewer pipe insertion groove 13, the fastening state is strong and excellent airtightness has the effect of preventing leakage.
