본 고안은 원심력 철근 콘크리트관의 소켓 접합 시공시 접합 부분에서의 누수를 방지하도록 하는 원심력 철근 콘크리트관의 누수 방지구에 관한 것이다.The present invention relates to a leak prevention port of the centrifugal reinforced concrete pipe to prevent leakage at the joint portion when the socket joint construction of the centrifugal reinforced concrete pipe.

분류식 오수관 및 합류식관에 사용되는 원심력 철근 콘크리트관은 성형틀안에 콘크리트를 투입시켜 가며 성형틀을 회전시켜 원심력을 이용하여 성형시키게 된다.Centrifugal force reinforced concrete pipes used for sorting sewage pipes and conduit pipes are made by using centrifugal force by rotating concrete while putting concrete in the mold.

이렇게 제작된 원심력 철근 콘크리트관의 시공 방법은 시공이 용이하고 용수배제가 곤란한 곳에서도 시공이 가능한 소켓 접합 방식을 이용하고 있다.The method of constructing the centrifugal reinforced concrete pipe thus manufactured uses a socket joining method that is easy to construct and that can be constructed even where water drainage is difficult.

소켓 접합 방식은 콘크리트관의 접합 부위에 고무링을 끼워 수밀성을 보장하고 있으며 이러한 소켓 접합의 시공 방법은 다음과 같다.Socket joining method is to ensure the watertightness by inserting a rubber ring in the joint of the concrete pipe, the construction method of such a socket joint is as follows.

새로 부설할 소켓관의 수구부(spigot)에 고무링을 끼우고 기부설된 소켓관의 삽구부(bell mouth)에 중심과 중심선을 일치시킨후 새로 부설할 소켓관의 수구부를 기 부설된 소켓관의 삽구부에 밀착시키면 된다.Put the rubber ring on the spout of the socket pipe to be newly installed, and match the center and center line to the bell mouth of the donated socket pipe, and then install the socket part of the socket pipe to be newly installed. It should be in close contact with the insertion part of the.

이때 너무 세게 밀착시키거나 한쪽으로 편중되게 밀착시키면 고무링이 찢어지는 수가 있고 너무 약하게 밀착시키면 접합부분의 일부가 틈이 생겨 수밀이 되지 않는 수가 있다.At this time, if you adhere too tightly or one-sided close contact with the rubber ring may be torn, too weak contact may be a part of the joint is not watertight because there is a gap.

그 이유는 고무링이 끼워지는 원심력 철근 콘크리트관의 삽구부 표면이 거칠어 수구부로 고무링을 밀을때 표면 마찰이 커서 고무링이 밀리지 않기 때문이다.The reason is that the surface of the insertion portion of the centrifugal reinforced concrete pipe into which the rubber ring is inserted is rough so that the rubber ring is not pushed because the surface friction is large when the rubber ring is pushed to the water port.

또한 삽구부의 표면이 거칠어 고무링이 삽입되더라도 고무링과의 기밀성이 낮아 완전 수밀을 기대할 수 없다.In addition, even when the rubber ring is inserted because the surface of the insertion part is rough, the airtightness with the rubber ring is low, so that the watertightness cannot be expected.

본 고안은 상기와 같은 점을 감안하여 소켓 접합 방식의 원심력 철근 콘크리트관의 삽구부 표면을 매끄럽게 해주어 삽입되는 고무링이 두틀리거나 찢어지지 않고 삽일될 수 있게 하며 삽구부와 고무링과의 기밀성을 높일수 있도록 한 것이다.In view of the above, the present invention smoothes the surface of the insertion section of the socket-bonded centrifugal reinforced concrete tube so that the inserted rubber ring can be inserted without twisting or tearing, and the airtightness between the insertion section and the rubber ring It is to increase.

이러한 목적의 본 고안은 원심력 철근 콘크리트관의 성형시 삽구부에 합성수지재의 누수 방지구를 결합시켜 일체로 성형되게 하므로써 삽구부 표면만 합성수지재가 되고 긔 이와는 콘크리트로 제작시키는 것이다.The present invention for this purpose is to combine the leakage prevention tool of the synthetic resin material into the insertion part when forming the centrifugal reinforced concrete tube to be integrally molded, so that only the surface of the insertion part becomes a synthetic resin material and is made of concrete.

이하 본 고안을 첨부 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안 누수 방지구의 사시도로써 누수 방지구(1)의 전체 형상은 원심력 철근 콘크리트관의 삽구부 형태와 동일하며 다만 콘크리트에 함입되어 결합력을 높이는 돌기(2)가 뒷면에 다수개 형성되고 콘크리트관 성형시 이탈을 방지하는 잡음편(3)이 4방형으로 형성된다.1 is a perspective view of the leak prevention device of the present invention, the overall shape of the leak prevention device (1) is the same as the shape of the insert portion of the centrifugal reinforced concrete pipe, but a plurality of protrusions (2) are embedded in the concrete to increase the coupling force on the back side Noise piece (3) is formed in a quadrangular shape to prevent separation when forming the concrete pipe.

여기서 돌기(2)는 표면적을 높여 콘크리트와의 결합력을 높이기 위해 단면이 십자가 형태르 유지하도록 형성시키되 그 설치 갯수는 문제가 되지 않는다.Wherein the projection (2) is formed to maintain the cross-section in the cross-section in order to increase the surface area to increase the bonding force with the concrete, but the number of installation is not a problem.

그리고 잡음편(3)은 굳이 4개를 설치하지 않고 그 갯수를 변화시킬 수 있으나 누수 방지구(1)가 회전력에 의해 성형틀에서 이탈되지 않게 잡아주면 된다.And the noise piece (3) can change the number without having to install four dares, but it is enough to hold the leakage preventing mechanism (1) so as not to be separated from the mold by the rotational force.

이때 누수 방지구(1)는 P. V. C 등의 합성 수지재를 이용한다.At this time, the leak prevention tool 1 uses synthetic resin materials, such as P.V.C.

이러한 누수 방지구(1)가 원심력 철근 콘크리트관의 삽구부(7) 표면을 이루도록 성형시키는 방법을 제2도에 의거 살펴본다.A method of forming such a leak prevention tool 1 to form the surface of the insertion part 7 of the centrifugal force reinforced concrete tube will be described based on FIG. 2.

콘크리트관(20)의 외면을 형성시키는 원통형의 외면 성형틀(4)의 일측은 삽구부(7)를 성형시키는 한편 수구부(8)를 성형시킨다.One side of the cylindrical outer surface forming mold 4 forming the outer surface of the concrete tube 20 forms the insert 7 and the water port 8.

수구부(8)쪽에는 수구부 성형틀(6)을 외면 성형틀(4)에 보울트(10)로 조여 준다.The water port part 8 is fastened to the water port part mold 6 by the bolt 10 to the outer mold 4.

이때 외면 성형틀(4) 보다 높은 수구부 성형틀(6)의 높이에 의해 콘크리트관(20)의 두께가 결정된다.At this time, the thickness of the concrete tube 20 is determined by the height of the water port forming mold 6 higher than the outer surface forming mold (4).

그리고 외면 성형틀(4)의 삽구부(7)쪽에는 누수 방지구(1)를 위치시키고 그 위로 삽구부 성형틀(5)을 위치시킨후 삽구부 성형틀(5)가 외면 성형틀(4)을 보울트(9)로 조여준다.Then, the leakage prevention tool 1 is positioned on the insertion part 7 side of the outer mold 4, and the insert part mold 5 is positioned thereon, and then the insert part mold 5 is formed on the outer mold 4 ) To the bolt (9).

이때 외면 성형틀(4)과 삽구부 성형틀(5)의 맞닿는 부분에 누수 방지구(1)의 잡음편(3)을 위치시켜 잡음편(3)이 외면 성형틀(4)과 삽구부 성형틀(5) 사이에 끼워져 회전시 원심력에 의해서 누수 방지구(1)가 이탈되지 않도록 한다.At this time, the noise piece 3 of the leakage preventing tool 1 is placed at the contact portion between the outer mold 4 and the insert molding die 5 so that the noise piece 3 is molded into the outer mold 4 and the insert. It is sandwiched between the molds (5) to prevent the leakage prevention device (1) is separated by the centrifugal force during rotation.

이때 누수 방지구(1)의 돌기(2)는 콘크리트관(20) 내측을 향하게 된다.At this time, the protrusion 2 of the leakage preventing opening 1 faces the inside of the concrete pipe 20.

이렇게 조립된 상태에서 외면 성형틀(4)을 회전시켜가며 콘크리트를 부으면 회전 원심력에 의해 콘크리트관(20)이 성형되게 된다.The concrete pipe 20 is molded by rotating centrifugal force when the concrete is poured while rotating the outer mold 4 in the assembled state.

즉 삽구부 성형틀(5)과 수구부 성형틀(6)이 결합된 외면 성형틀(4)을 회전시켜가며 외면 성형틀(4)의 내측으로 콘크리트를 부으면 삽구부 성형틀(5)과 수구부 성형틀(6)의 높이만큼 두께를 갖는 콘크리트관(20)을 성형시키게 된다.That is, when the concrete is poured into the outer mold 4 by rotating the outer mold 4 in which the insert part mold 5 and the water mold part 6 are combined, the insert mold 5 and the water tool The concrete pipe 20 having a thickness as high as the height of the secondary mold 6 is molded.

이렇게 성형된 콘크리트관(20)의 삽구부(7)에는 누수 방지구(1)가 결합된 상태가 된다.The inserting portion 7 of the concrete pipe 20 formed as described above is in a state in which the leakage preventing tool 1 is coupled.

여기서 누수 방지구(1)의 돌기(2)는 콘크리트관(20) 내부로 함입되어 콘크리트관(20)의 삽구부(7)에서 누수 방지구(1)가 이탈되지 않게 된다.Here, the protrusion 2 of the leakage preventing device 1 is recessed into the concrete pipe 20 so that the leakage preventing device 1 is not separated from the insertion part 7 of the concrete pipe 20.

그리고 보울트(9)(10)를 풀어 외면 성형틀(4)과 삽구부 성형틀(5) 및 수구부 성형틀(6)을 해체시키면 제3도에 도시된 바와 같은 콘크리트관(20)이 완성된다.Then, the bolts (9) and (10) are released to disassemble the outer mold (4), the insert mold (5), and the tool mold (6), and the concrete tube 20 as shown in FIG. 3 is completed. do.

즉 기존의 삽구부(7)가 콘크리트로 형성되는 것과는 달리 본 고안은 삽구부(7)가 합성수지재의 누수 방지구(1)로 형성되는 것이다.In other words, unlike the conventional inserting portion 7 is formed of concrete, the present design is that the inserting portion 7 is formed as a leak prevention device 1 of the synthetic resin material.

제3도와 같이 성형된 후에는 칼로써 잡음편(3)을 콘크리트관(20)의 외경에 맞추어 잘라내면 된다.After molding as shown in FIG. 3, the noise piece 3 may be cut out using a knife to match the outer diameter of the concrete pipe 20.

완성된 콘크리트관(20)을 이용하여 소켓 접합시킨 상태의 단면도는 제4도에 도시된 바와 같다.The cross-sectional view of the socket-bonded state using the completed concrete pipe 20 is as shown in FIG.

여기서 수구부(8)에 고무링(11)을 끼워 다른관의 삽구부(7)에 밀어 넣으면 고무링(1)은 수구부(8)에 밀리면서 삽구부(7) 내부로 밀려 들어가게 된다.When the rubber ring 11 is fitted to the water port 8, the rubber ring 1 is pushed into the insertion hole 7 of the other tube while being pushed into the water hole 8 while being pushed into the water hole 8.

이때 삽구부(7) 표면이 합성수지재의 누수 방지구(1)로 되어 있어 고무링(11)은 두틀리거나 찢어지는 경우 없이 정밀하게 삽입되어진다.At this time, the surface of the insertion part 7 is made of a leakage preventing device 1 of the synthetic resin material, so that the rubber ring 11 is precisely inserted without being twisted or torn.

즉 기존의 삽구부(7)가 콘크리트로 되어 있어 표면이 거친 관계로 고무링(11)과 표면과의 마찰력이 커서 고무링(11)이 제대로 삽입되지 않고 설사 삽입되더라도 거친 표면과의 기밀성 유지가 되지 않아 누수되는 현상이 발생되었으나 본 고안에서는 누수 방지구(1)의 표면이 매끄러워 고무링(11)이 원할히 삽입되면 또한 누수 방지구(1)의 표면과 고무링(11)과의 기밀성이 확실히 유지된다.In other words, since the existing inserting portion 7 is made of concrete and the surface is rough, the frictional force between the rubber ring 11 and the surface is large, so even if the rubber ring 11 is not properly inserted and diarrhea is inserted, airtightness with the rough surface is maintained. In this invention, when the rubber ring 11 is smoothly inserted, the surface of the water leak prevention device 1 and the airtightness of the rubber ring 11 are also leaked. It is certainly maintained.

한편 본 고안의 누수 방지구(1)는 원심력 철근 콘크리트관(20)의 제조시에만 사용되지 않고 성형틀을 진동시켜가며 흔들어 주어 제작하는 바이브레이션 롤링관의 제조시에도 바이브레이션 롤링관의 삽구부에 형성시켜 이용할 수 있다.Meanwhile, the leakage preventing device 1 of the present invention is not used only in the manufacture of the centrifugal reinforced concrete pipe 20, but is formed in the insert portion of the vibration rolling tube even when the vibration rolling tube is manufactured by shaking and shaking the forming mold. It can be used.

즉 바이브레이션 롤링과의 성형틀에 누수 방지구(1)를 고정시킨 후 관을 성형시킴으로써 바이브레이션 롤링관의 삽구부에 누수 방지구(1)를 일체로 형성시켜도 된다.In other words, the water leakage prevention tool 1 may be integrally formed with the insertion part of the vibration rolling tube by fixing the water leakage prevention tool 1 to the forming mold with the vibration rolling.

이상에서 살펴본 바와 같이 본 고안은 원심력 철근 콘크리트관의 소켓 접합 방식에서 콘크리트관의 삽구부 표면을 합성수지재의 누수 방지구로 형성시킴으로써 고무링이 뒤틀리거나 찢어지는 경우없이 정확히 삽입되며 고무링과의 기밀성을 확실히 유지시켜 누수가 되지 않는 효과가 제공된다.As described above, the present invention forms the insertion surface of the concrete pipe as a leakage preventing device of synthetic resin in the socket jointing method of the centrifugal reinforced concrete pipe, so that the rubber ring is correctly inserted without being twisted or torn, and the airtightness with the rubber ring is ensured. It provides the effect of keeping it from leaking.
