Description

배수용 본관에 지관을 연결하는 장치{Device that connects the branch pipes to the main pipe for drainage}Device that connects the branch pipes to the main pipe for drainage

본 발명은 배수용 본관에 지관을 연결하는 장치에 관한 것으로서, 더욱 상세하게는 배수를 위해 지하에 매설하는 본관에 지관을 매우 신속·용이하고도 견고하게 결합하여 연결할 수 있도록 하는 배수용 본관에 지관을 연결하는 장치에 관한 것이다.The present invention relates to a device for connecting a branch pipe to a main pipe for drainage, and more particularly, to a main pipe for drainage that allows a branch pipe buried underground for drainage to be connected very quickly, easily and firmly. It relates to a device that connects.

종래에는, 내경의 개구부 양쪽에 지관이 삽입되는 방향으로 경사진 래치트돌출링들이 형성되고 래치트돌출링들의 사이에 래치트돌출링 보다 낮은 칫수의 요홈둘레면이 형성된 연결구본체의 걸림돌기들이 형성되어 있는 개구구멍결합면을 본관에 뚫은 개구구멍에 억지맞춤으로 삽입결합하여 걸림돌기들에 의해 연결구본체가 개구구멍으로부터 빠지지 않게 본관에 결합되고, 상기 연결구본체에 지관을 삽입하여 래치트돌출링들이 지관의 둘레면에 긴밀하게 접촉 고정되면서 래치트돌출링들과 래치트돌출링들 사이에 형성되는 충전공간에 의해 지관이 연결구본체내에 기밀을 유지하면서 긴축력있게 고정되도록 하는 배수관용 본관의 지관 연결구(등록실용신안 제20-0469234호)가 있었다.Conventionally, ratchet protrusions inclined in the direction in which the branch pipe is inserted at both sides of the opening of the inner diameter are formed, and locking protrusions of the connector body formed with a groove dimension of a lower dimension than the ratchet protrusion ring are formed between the ratchet protrusion rings. The connecting hole main body is inserted into the main hole so that the connecting hole main body does not come out of the opening hole by forcefully inserting the opening hole engaging surface into the opening hole drilled in the main tube, and ratcheting rings are inserted by inserting the branch tube into the connecting body. While being in close contact with the circumferential surface of the pipe, the branch pipe connector of the main pipe for a drain pipe that allows the branch pipe to be tightly fixed while maintaining airtightness in the main body of the connector body by the filling space formed between the rat projection protrusions and the rat protrusion protrusions ( There was a utility model registration number 20-0469234).

그러나, 이러한 배수관용 본관의 지관 연결구는, 연결구본체를 본관에 뚫은 개구구멍에 삽입결합할 때 연결구본체의 걸림돌기들이 형성되어 있는 개구구멍결합면을 개구구멍에 억지맞춤으로 삽입하여야 하므로 이들을 결합하는데 많은 힘과 시간이 소요되는 등의 문제점은 물론이고, 연결구본체의 개구구멍결합면을 두께가 한정된 본관에 뚫은 개구구멍에 삽입하면 외단이 개구구멍의 내면에 접촉되는 걸림돌기들에 의해서만 연결구본체와 본관의 결합이 유지되는 것이므로, 개구구멍과 걸림돌기들이 접촉하게 되는 면적이 걸림돌기들의 외단으로 제한되어 이들의 결합력이 떨어져 쉽게 이완되기 때문에 이들 사이에서 누수가 발생하거나 심한 경우에는 연결구본체가 분리되는 등의 문제점들이 있었다.However, the branch pipe connector of the main pipe for the drain pipe is coupled to the opening hole coupling surface in which the locking projections of the connector body are formed into the opening hole when the connector body is inserted into the opening hole drilled in the main pipe. As well as problems such as time-consuming and time-consuming, when the opening hole coupling surface of the connecting body is inserted into the opening hole drilled in the main tube having a limited thickness, the connecting hole main body and the main body are connected only by locking protrusions in which the outer end contacts the inner surface of the opening hole. Since the coupling of the retaining hole is maintained, the area in which the opening hole and the locking protrusions are contacted is limited to the outer ends of the locking protrusions, and their coupling force is easily separated to loosen them, so that leakage occurs between them or, in severe cases, the connector body is separated, etc. There were problems.

또한, 외경이 연결구본체의 내경보다 작은 지관의 일 단부를 연결구본체에 삽입하면, 내단이 지관의 외면에 접촉되는 래치트돌출링들에 의해서만 지관의 일 단부와 연결구본체의 연결상태가 유지되는 것이므로, 지관의 외면과 래치트돌출링들이 접촉하게 되는 면적이 래치트돌출링들의 내단으로 제한되어 이들의 고정력이 떨어져 쉽게 이완되기 때문에 이들 사이에서 누수가 벌생하거나 심한 경우에는 연결구본체가 분리되는 등의 문제점도 있었다.In addition, when one end of the branch pipe whose outer diameter is smaller than the inner diameter of the connecting body is inserted into the connecting body, the connection state between the one end of the branch pipe and the connecting body is maintained only by ratchet protrusion rings whose inner end contacts the outer surface of the branch pipe. Since the area where the ratchet protrusion rings come into contact with the outer surface of the branch pipe is limited to the inner ends of the ratchet protrusion rings, their holding force is easily loosened, so that leakage occurs between them or, in severe cases, the connector body is separated. There were also problems.

또한, 종래에는 경질의 플라스틱으로 주름의 단면이 "

"형태로 성형된 주름관으로 지관을 본관에 연결하기도 하였는데, 이러한 주름관의 주름들은 각 상사점들 사이 및 하사점들 사이의 간격이 크고 상사점과 하사점들을 이어주는 좌·우경사면들이 45°정도의 각도로 경사지게 형성되어 있기 때문에 힘을 주어 주름관을 구부려줄 때 가해지는 압력이 경사가 완만하고 동일한 각도의 좌·우경사면에 의해 좌우에서 이들의 중간에 위치하는 각 상사점과 하사점에 동시에 가해지므로 상사점과 하사점들에서 반력이 발생하여 이들이 잘 오므려지거나 벌어지지 않게 됨에 따라 주름관이 용이하게 굽혀지지 않아 강한 힘으로 주름관을 굽혀주어야 하므로 작업성이 크게 저하됨은 물론 굽혀지는 정도도 크지 않게 되는 등의 문제점도 있었다.In addition, conventionally, the cross section of the wrinkle is made of hard plastic. "

"It was also connected to the main tube by a corrugated pipe shaped into a shape. The corrugations of these corrugated pipes have a large gap between each top dead center and bottom dead centers, and the left and right inclined surfaces connecting the top and bottom dead centers are around 45 °. Since it is formed to be inclined at an angle, the pressure exerted when bending the corrugated tube by applying force is applied to each of the top and bottom dead centers located in the middle of the left and right sides at the same time by the left and right slopes of the same angle. As the reaction force is generated at the top dead center and the bottom dead center, they are not easily bent or opened, so the corrugated pipe should not be easily bent, so the corrugated pipe must be bent with strong force, so the workability is greatly reduced and the degree of bending is not large. There were also problems such as.

이하, 본 발명에 따른 배수용 본관에 지관을 연결하는 장치를 첨부된 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, an apparatus for connecting a branch pipe to a main pipe for drainage according to the present invention will be described in detail with reference to the accompanying drawings.

도 1~3의 본 발명에 따른 배수용 본관에 지관을 연결하는 장치는, 고정관부재(10)와, 상기 고정관부재에 전단부를 삽입결합하는 연결관부재(20) 및 상기 연결관부재의 후단에 결합하는 패킹관부재(30)를 포함하여 구성된다.The apparatus for connecting the branch pipe to the main pipe for drainage according to the present invention of FIGS. 1 to 3 includes a fixed pipe member 10, a connecting pipe member 20 for inserting a front end portion to the fixed pipe member, and a rear end of the connecting pipe member. It comprises a packing tube member 30 to be coupled.

고정관부재(10)는, 외면의 외경과 내외길이는 본관(40)에 천공되는 고정공(41)의 내경과 내외두께에 대응하고 내면은 내경이 외단에서 내단으로 갈수록 점차 작아지는 경사면으로 형성되는 관부(11)와, 상기 관부 외면의 외단에 빙둘러 돌출되어 고정공의 외주면에 밀착되는 플랜지부(12)와, 상기 관부의 내면에 형성되는 암나선(13) 및 상기 관부의 내단부분에 일정간격으로 형성되는 절개선(14)을 구비하여 된다.The fixed pipe member 10, the outer diameter and inner and outer lengths of the outer surface correspond to the inner diameter and the inner and outer thickness of the fixing hole 41 perforated in the main pipe 40, and the inner surface is formed of an inclined surface that gradually decreases in diameter from the outer end to the inner end. The pipe portion 11, the flange portion 12 protruding to the outer circumference of the outer surface of the pipe portion to be in close contact with the outer circumferential surface of the fixing hole, the female spiral 13 formed on the inner surface of the pipe portion and the inner end portion of the pipe portion It is provided with a cutting line 14 formed at intervals.

이러한 고정관부재(10)는 고무나 우레탄 등의 고탄성체로 성형되며, 외경이 본관(40)에 천공되는 고정공(41)의 내경에 대응하기 때문에 신속·용이하게 삽입하여 결합할 수 있게 된다.The fixed tube member 10 is formed of a high elastic body such as rubber or urethane, and the outer diameter corresponds to the inner diameter of the fixing hole 41 drilled in the main tube 40, so that it can be quickly and easily inserted and combined.

또한, 관부(11)는 외경이 고정공(41)의 내경에 대응하는 반면에 내면은 내경이 외단에서 내단으로 갈수록 점차 작아지는 경사면으로 형성되는 것이므로, 상기 관부의 두께는 외단에서 내단으로 갈수록 점차적으로 두껍게 된다.In addition, since the outer diameter of the tube portion 11 corresponds to the inner diameter of the fixing hole 41, the inner surface is formed of an inclined surface that gradually decreases as the inner diameter goes from the outer edge to the inner edge, so the thickness of the pipe portion gradually increases from the outer edge to the inner edge. As thick as.

연결관부재(20)는 경질의 플라스틱으로 성형되며, 주름관부(21)와, 상기 주름관부의 내단에서 관부(11)의 경사진 내면의 경사도 보다 완만한 경사로 연장되어 관부의 내부에 삽입결속되는 결속관부(22)와, 상기 결속관부의 외면에 암나선(13)에 체결되게 형성되는 수나선(23) 및 내경이 상기 주름관부의 내경에 대응하게 주름관부의 외단에서 연장되는 연결관부(24)를 구비하여 된다.The connecting pipe member 20 is formed of a hard plastic, and the corrugated pipe portion 21 and the inclined inner surface of the pipe portion 11 at the inner end of the corrugated pipe portion extend at a more gentle slope than the inclined surface to be inserted and bound inside the pipe portion. A pipe portion 22, a male thread 23 formed to be fastened to the female thread 13 on the outer surface of the binding pipe portion, and a connecting pipe portion 24 having an inner diameter extending from the outer end of the corrugated pipe portion corresponding to the inner diameter of the corrugated pipe portion It is done.

패킹관부재(30)는 연질의 고무나 우레탄 등의 탄성체로 성형되며, 연결관부(24)의 외단이 삽입결속되는 결속홈(311)이 빙둘러 형성되는 관체부(31)와, 상기 관체부의 내주면에서 소정길이로 연장되는 패킹부(32)와, 상기 패킹부의 내면 외단측부분에 지관(50)의 삽입방향으로 경사지게 돌출형성되는 패킹턱부(33) 및 상기 패킹부의 내단에서 내측으로 경사지게 연장되며 내측은 평면으로 되고 외측은 만곡형성되는 패킹링부(34)를 구비하여 된다.The packing tube member 30 is formed of an elastic body such as soft rubber or urethane, and the tube 31 is formed with a binding groove 311 in which the outer end of the connecting tube 24 is inserted and bound, and the tube part The packing portion 32 extending from the inner circumferential surface to a predetermined length, the packing jaw portion 33 formed to protrude inclined in the insertion direction of the branch pipe 50 to the outer end portion of the inner surface of the packing portion, and extending inwardly from the inner end of the packing portion The inner side is flat and the outer side is provided with a packing ring portion 34 that is curved.

이와 같이 구성되는 본 발명에 따른 배수용 본관에 지관을 연결하는 장치의 사용상태를 설명하면 다음과 같다.When using the apparatus for connecting the branch pipe to the main pipe for drainage according to the present invention configured as described above is as follows.

도 4는 도 1의 장치로 본관에 지관을 연결한 상태를 보인 확대 단면도이고, 도 5는 도 4에서 "A"부분을 발췌 확대하여 보인 단면도이며, 도 6은 도 4에서 "B"부분을 발췌 확대하여 보인 단면도이다.FIG. 4 is an enlarged cross-sectional view showing a state in which a branch pipe is connected to the main tube with the apparatus of FIG. 1, FIG. 5 is a cross-sectional view showing an enlarged excerpt of the portion “A” in FIG. 4, and FIG. 6 is a portion “B” in FIG. 4 It is an enlarged cross-sectional view.

도 4~6에서와 같이 본관(40)에 지관(50)을 연결할 때에는, 먼저 본관(40)에 천공되는 고정공(41)에 고정관부재(10)의 관부(11)를 삽입하여 플랜지부(12)의 내면이 상기 고정공의 외주면에 밀착되도록 결합한다.4 to 6, when connecting the branch pipe 50 to the main pipe 40, first insert the pipe portion 11 of the fixed pipe member 10 into the fixing hole 41 that is drilled in the main pipe 40, and then the flange portion ( 12) so that the inner surface of the fixing hole is in close contact with the outer surface.

이후, 연결관부재(20)의 결속관부(22)를 고정공(41)에 결합된 고정관부재(10)의 관부(11)에 삽입하여 수나선(23)이 암나선(13)에 완전히 체결되도록 상기 연결관부재를 회전시켜 준다.Subsequently, the male thread 23 is completely fastened to the female thread 13 by inserting the binding pipe 22 of the connecting pipe member 20 into the pipe 11 of the fixed pipe member 10 coupled to the fixing hole 41 The connector member is rotated as much as possible.

이렇게 수나선(23)이 암나선(13)에 완전히 체결되는 과정에서, 결속관부(22)의 경사가 관부(11)의 내면 경사보다 완만하기 때문에 이들의 경사도 차이에 비례하여 상기 결속관부가 관부의 내단부분을 벌려주게 된다.In this way, in the process in which the male thread 23 is completely fastened to the female thread 13, since the slope of the binding pipe part 22 is gentler than the inner surface slope of the pipe part 11, the binding tube part is proportional to the difference in their inclination. Will open the inner rim of the.

이때, 관부(11)의 내단부분에는 일정간격으로 절개선(14)이 형성되어 있기 때문에 내단부분이 순조롭게 벌려지게 되는 것이며, 아울러 상기 관부의 두께가 외단에서 내단으로 갈수록 점차적으로 두껍게 되어 있으므로 벌려지는 정도가 크지 않아도 관부의 외면은 고정공(41)의 내면에 긴밀하게 밀착 고정된다.At this time, since the incision line 14 is formed at regular intervals in the inner end portion of the pipe portion 11, the inner end portion is smoothly spread, and the thickness of the pipe portion gradually increases from the outer end to the inner end, which is wider. Even if the degree is not large, the outer surface of the tube portion is closely fixed to the inner surface of the fixing hole 41.

따라서, 관부(11)에 결속관부(22)를 삽입하여 결합하는 것만으로도 임의로 분리되지 않도록 견고하게 고정됨과 동시에 고정공(11)과 상기 관부의 결합면들 사이에서 누수도 발생하지 않게 된다.Therefore, it is firmly fixed so as not to be arbitrarily separated only by inserting and engaging the binding tube portion 22 in the pipe portion 11 and at the same time, no leakage occurs between the fixing hole 11 and the coupling surfaces of the pipe portion.

이와 같이 관부(11)에 결속관부(22)를 삽입연결하여 고정관부재(10)를 본관(40)에 고정시킨 다음에는, 결속홈(311)에 연결관부(24)의 외단이 삽입되게 패킹관부재(30)를 상기 연결관부재(20)에 결합하여 설치한다.As described above, after the binding pipe portion 22 is inserted and connected to the pipe portion 11 to fix the fixed pipe member 10 to the main pipe 40, the packing pipe is inserted such that the outer end of the connection pipe portion 24 is inserted into the binding groove 311. The member 30 is installed to be coupled to the connecting tube member 20.

이렇게 패킹관부재(30)를 설치하면, 패킹부(32)와 패킹링부(34)의 만곡된 외측면은 연결관부(24)의 내면 외단측에 접촉하게 된다.When the packing tube member 30 is installed in this way, the curved outer surfaces of the packing part 32 and the packing ring part 34 come into contact with the outer end side of the inner surface of the connecting tube part 24.

이러한 상태에서, 외경이 관체부(31) 내면의 내경에 대응하는 지관(50)의 내단부를 패킹부(32)의 내측으로 삽입하면, 상기 지관의 외면이 패킹턱부(33)와 패킹링부(34)를 외측으로 가압하기 때문에 상기 패킹부와 패킹링부의 만곡된 외측면은 연결관부재(20)의 내면에 긴밀하게 밀착되고, 상기 패킹부와 패킹턱부 및 패킹링부의 내측면은 지관의 외면에 긴밀하게 밀착된다.In this state, when the inner diameter of the inner tube of the branch pipe 50 whose outer diameter corresponds to the inner diameter of the inner surface of the tube body portion 31 is inserted into the packing portion 32, the outer surface of the branch pipe has a packing jaw portion 33 and a packing ring portion 34 ), The curved outer surface of the packing part and the packing ring part is in close contact with the inner surface of the connecting pipe member 20, and the inner surface of the packing part, the packing jaw part and the packing ring part is on the outer surface of the branch pipe. Tight fit.

따라서, 연결관부재(20)와 지관(50)은 패킹관부재(30)를 매개로 하여 임의로 분리되지 않도록 서로 견고하게 결합고정됨과 동시에 각 결합면들 사이에서 누수도 발생하지 않게 된다.Therefore, the connecting pipe member 20 and the branch pipe 50 are firmly fixed to each other so as not to be arbitrarily separated via the packing pipe member 30, and at the same time, no leakage occurs between the respective coupling surfaces.

한편, 상기에서는 연결관부재(20)를 고정관부재(10)에 결합한 다음 패킹관부재(30)를 상기 연결관부재에 결합하는 것으로 되어 있으나 반드시 이에 한정되는 것은 아니며, 필요에 따라서는 상기 패킹관부재를 연결관부재에 먼저 결합한 후 연결관부재를 고정관부재에 결합하여도 된다.On the other hand, in the above, the connecting pipe member 20 is coupled to the fixed pipe member 10, and then the packing pipe member 30 is coupled to the connecting pipe member, but is not limited thereto, and if necessary, the packing pipe The member may be first coupled to the connecting tube member, and then the connecting tube member may be coupled to the fixed tube member.

도 7은 도 2에서 연결관부재의 주름관부 일부를 발췌 확대하여 보인 단면도이고, 도 8은 도 2의 연결관부재를 사용한 지관의 다른 연결상태를 보인 단면도이다.7 is a cross-sectional view showing an enlarged excerpt of a part of the corrugated pipe portion of the connecting pipe member in FIG. 2, and FIG. 8 is a cross-sectional view showing another connection state of the branch pipe using the connecting pipe member of FIG.

도 7에서와 같이 주름관부(21)는, 주름들의 각 상사점(211)과 그 좌우의 하사점(212)들을 이어주게 하향연장되는 좌측경사면(213)의 경사각도(r)와 우측경사면(214)의 경사각도(r')를 상기 각 하사점의 중간을 기준으로 하여 좌측경사면의 경사각도 보다 우측경사면의 경사각도를 크게 형성한다.As shown in FIG. 7, the corrugated pipe portion 21 includes an inclined angle r and a right inclined surface of the left inclined surface 213 extending downwardly to connect the respective top dead centers 211 of the wrinkles and the bottom left and right 212 points of the wrinkles ( Based on the inclination angle r 'of 214), the inclination angle of the right inclined surface is made larger than that of the left inclined surface based on the middle of each of the bottom dead center points.

일 예로, 좌측경사면(213)의 경사각도(r)를 12°정도로 할 때 우측경사면(214)의 경사각도(r')는 24°정도로 되게 한다.For example, when the inclination angle r of the left inclined surface 213 is about 12 °, the inclination angle r 'of the right inclined surface 214 is about 24 °.

이렇게 하면, 상·하사점(21)(212)들이 좌·우측경사면(213)(214)들 사이의 중간이 아닌 상기 좌측경사면에 근접하는 위치에 치우쳐있게 되므로 연결관부(24)의 후단을 상향시켜 주름관부(21)를 상방으로 구부려줄 때 가해지는 압력이 상기 좌·우측경사면들을 통해 좌우에서 동일하게 각 상·하사점에 가해지지 않게 되기 때문에 상·하사점에서 반력이 발생하지 않게 되어 구부려주는 정도에 따라 상·하사점들이 용이하게 오므려지거나 벌어지게 되므로 큰 힘을 들이지 않고도 주름관부를 원하는 상태로 신속·용이하게 굽혀줄 수 있게 된다.In this way, the upper and lower dead centers 21 and 212 are biased to a position closer to the left tilted surface than to the middle between the left and right tilted surfaces 213 and 214, so that the rear end of the connecting pipe portion 24 is raised. As the pressure applied when bending the corrugated pipe portion 21 upwards is not applied to each of the upper and lower dead centers equally from the left and right through the left and right inclined surfaces, the reaction force is not generated at the upper and lower dead centers, so that the bending force is not bent. Depending on the degree of giving, the top and bottom dead centers are easily retracted or opened, so it is possible to quickly and easily bend the corrugated pipe into a desired state without applying great force.

이와 같은 본 발명에 따른 배수용 본관에 지관을 연결하는 장치는, 그 구조가 간단하고 본관에 지관을 매우 신속·용이하고도 견고하게 결합고정되도록 함과 동시에 장기간이 경과하여도 임의로 분리되거나 결합면들 사이에서 누수가 발생하지 않게 되도록 하는 등의 특징이 있다.The apparatus for connecting the branch pipe to the main pipe for drainage according to the present invention has a simple structure and allows the branch pipe to be fastened to the main pipe very quickly, easily and firmly, and at the same time, is separated or combined arbitrarily even after a long period of time. There are features such as preventing leakage from occurring.
