본 고안은 상수도용 주철관을 연결함에 있어 주철관과 이와 접촉되는 이탈방지 압륜의 고정받침쇠간의 접지면을 증대시켜 체결력을 강화하고, 이탈방지 압륜에 나사 결합되는 체결볼트에 의해 고정받침쇠에 가해지는 체결력이 주철관 조립부측으로 작용하게 하여 외부에서 충격이 가해지더라도 이탈방지 압륜에 지지 고정되는 주철관이 쉽게 이탈되는 것을 방지하도록 한 이탈방지 압륜에 관한 것이다.The present invention enhances the fastening force by increasing the ground surface between the cast iron pipe and the fixing support of the release prevention pressure ring in contact with the waterworks cast iron pipe, and is applied to the fixing support by the fastening bolt screwed to the release prevention pressure wheel. The clamping force acts on the cast-iron pipe assembly side, and even if an impact is applied from the outside to prevent the separation of the cast-iron pipe that is supported and fixed to the release-proof pressure wheel to prevent the separation.

일반적으로 이탈방지용 주철관은 일정한 단위 길이로 되는 주철관을 필요한 만큼 연속되게 연결하여 된 것으로, 상수도 주철관은 주철관과 주철관이 연결되는 연결부위의 누수 방지 및 기밀 유지가 절대적으로 필요하다.In general, the cast-iron pipe for prevention of departure is made by continuously connecting the cast iron pipe having a constant unit length as necessary, and the waterworks cast iron pipe is absolutely necessary to prevent leakage and maintain airtightness at the connection portion between the cast iron pipe and the cast iron pipe.

이러한 상수도용 주철관은 제1도와 같이 주철관(1)의 일측단부에 주철관(2)이 끼워지는 조립부(10)를 형성하여 상기 조립부(10)의 내측에 기밀 유지를 위한 패킹(3)과 함께 주철관(2)을 끼워 넣은 다음 상기 패킹(3)과 조립부(10)의 외주면을 체결하도록 된 별도의 이탈방지 압륜(4)을 이용하여 조립 체결하는 시공 방법이 주로 이용되고 있다.The cast iron pipe for waterworks forms an assembling part 10 into which the cast iron pipe 2 is fitted at one end of the cast iron pipe 1 as shown in FIG. 1, and the packing 3 for airtightness is maintained inside the assembling part 10. A construction method of inserting the cast iron pipe 2 together and then assembling and fastening using a separate release preventing pressure ring 4 to fasten the outer circumferential surface of the packing 3 and the assembly part 10 is mainly used.

그리고 주철관(1)과 주철관(2)이 끼워지는 조립부(10)를 감싸도록 된 이탈방지 압륜(4)에는 그 일측에 방사상으로 고정 배치되어 상기 이탈방지 압륜(4)에 나사 결합되는 체결볼트(6)에 조립되는 고정받침쇠(5)가 조립부(10)에 끼워지는 상대 주철관(2)의 외주면을 가압하도록 되어 있다.And the fixing bolt radially fixed to one side of the cast-resistant pipe (4) to surround the assembly portion 10, the cast iron pipe (1) and the cast iron pipe (2) is fitted is screwed to the separation preventing pressure wheel (4) The fixing base 5 to be assembled to (6) presses the outer circumferential surface of the mating cast iron pipe 2 fitted into the assembly section 10.

그렇지만 종래에는 제4도(a)와 같이 주철관(2)과 접촉되는 고정받침쇠(5)의 접지면(55)이 양쪽 끝단이 뾰족하게 돌출되는 돌출부(56,57)를 형성하여 상기 돌출부(56,57)가 주철관(2)의 외주면을 가압 고정되도록 구성되고 있다.However, in the related art, as shown in FIG. 4A, the ground surface 55 of the fixing support 5 which is in contact with the cast iron pipe 2 forms protrusions 56 and 57 at which both ends protrude sharply. 56 and 57 are configured to press-fix the outer circumferential surface of the cast iron pipe 2.

이러한 종래의 고정받침쇠(5)를 이용하여 주철관(2)의 외주면을 고정하게 되면 제4도(b)와 같이 주철관(2)의 외주면에 돌기부(56)만이 접지되는 관계로 주철관과 접촉되는 접촉면이 작아 그다지 견고한 체결력을 유지할 수 없고, 주철관(2)을 고정하는 고정받침쇠(5)의 접지면(55)을 뾰쪽하게 형성하고 있어 이와 접촉되는 주철관(2)에 흠집을 남기게 되어 주철관이 쉽게 부식되거나 파손되는 문제점으로 인해 상수도용 주철관의 수명이 크게 단축되는 문제점이 있었다.When the outer circumferential surface of the cast iron pipe 2 is fixed by using the conventional fixing support 5, as shown in FIG. 4 (b), only the protrusion 56 is grounded on the outer circumferential surface of the cast iron pipe 2, so that it is in contact with the cast iron pipe. Since the contact surface is small and cannot maintain a very strong fastening force, the ground surface 55 of the fixing support 5 for fixing the cast iron pipe 2 is sharply formed, leaving a scratch on the cast iron pipe 2 which is in contact with the cast iron pipe. Due to the problem of easily corroded or broken, there was a problem in that the life of the cast iron pipe for water supply is greatly shortened.

본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 상수도용 주철관을 연결함에 있어 이탈방지용 압륜에 조립되는 고정받침쇠와 주철관의 접촉되는 접지면을 크게하여 체결력을 강화하고, 고정받침쇠에 가해지는 체결력이 주철관 조립부측으로 향하게 하여 암·수결합되는 주철관의 틀새가 최소화할 수 있는 이탈방지 압륜을 제공하는 그 목적이 있다.The present invention is to solve such a conventional problem, in connecting the cast iron pipe for water supply, to increase the fastening force by increasing the grounding surface of the fixed support and the cast iron pipe to be fixed to the separation prevention pressure ring, which is applied to the fixed support The object of the present invention is to provide a release preventing pressure ring which can minimize the mold of the cast iron pipe to be clamped to the cast iron pipe assembly side.

본 고안은 이러한 목적을 달성하기 위하여, 체결볼트에 상대 주철관을 가압 고정하는 고정받침쇠의 접지부가 양측으로부터 중앙 상면으로 돌출시킨 접지부의 선단이 중심 일측으로 편심되게 하여 한쪽 면이 완만한 경사기울기를 가지도록 하고, 상기 접지부 선단은 좌·우 양측으로부터 내측 중앙부위가 오목하게 형성되는 곡면을 이루도록 구성됨을 특징으로 하고 있다.In order to achieve this object, the present invention, the grounding portion of the fixed support which press-fixes the mating cast iron pipe to the fastening bolt to the center of one side of the ground portion protruding from both sides to the center of one side eccentric tilt slope slope The front end of the ground portion is characterized in that it is configured to form a curved surface in which the inner central portion is formed concave from both left and right sides.

이하, 본 고안을 첨부된 예시 도면을 참고하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제1도는 암·수결합되는 주철관과 주철관이 연결되는 조립부를 고정받침쇠가 구비되는 이탈방지 압륜을 이용하여 조립 체결되는 것을 나타낸 단면도이고, 제2도는 본 고안에 따른 이탈방지 압륜에 사용되는 고정받침쇠에 형성되는 접지부를 묘사하고 있는 저면도이다.1 is a cross-sectional view showing the assembling and fastening using a separation prevention pressure ring provided with a fixing support for the cast iron pipe and the cast iron pipe is a male and male coupling is connected, Figure 2 is fixed to be used in the separation prevention pressure wheel according to the present invention Bottom view depicting the grounding part formed on the support.

주철관(1)과 주철관(2)이 끼워지는 조립부(10)를 감싸도록 된 이탈방지 압륜(4)의 일측에 방사상으로 배치되어 나사 결합되는 체결볼트(6)에 상대 주철관(2)의 외주면을 가압시키며 고정되는 고정받침쇠(5)가 구비되는 것에 있어서, 주철관(2)과 접촉되는 상기 고정받침쇠(5)의 접지면이 양측단으로부터 중앙 상면으로 돌출시켜 접지면(55)의 선단(51)이 중심 일측으로 편심되게 하여 한쪽면(52)이 완만한 경사기울기를 가지게 하고, 상기 접지부(50)의 선단(51)은 양끝단으로부터 내측 중앙부(53)가 오목한 곡면라운드를 가지도록 구성됨을 특징으로 하고 있다.The outer circumferential surface of the mating cast iron pipe 2 to the fastening bolt 6 radially disposed and screwed on one side of the anti-separation pressure ring 4 to surround the assembly portion 10 into which the cast iron pipe 1 and the cast iron pipe 2 are fitted. In the fixed support (5) is provided to press and fixed to, the ground surface of the fixed support (5) in contact with the cast iron pipe (2) protrudes from both ends to the center upper surface of the front end of the ground surface (55) The 51 is eccentric to one side of the center so that one side 52 has a gentle slope, and the front end 51 of the ground portion 50 has a rounded surface with a concave central inner portion 53 from both ends. It is configured to be.

상기 체결볼트(6)와 고정받침쇠(5)는 상호 분해 조립이 가능하도록 되고, 고정받침쇠(5) 접지부(50)의 내측 중앙부(53)에 오목하게 형성되는 곡면라운드 주철관(1)의 외직경과 동일하거나 크게 형성하는 것이 바람직하다.The fastening bolt 6 and the fixing support 5 can be mutually disassembled, and the curved round cast iron pipe 1 is formed concave in the inner central portion 53 of the fixing support 5 and the ground portion 50. It is preferable to form the same or larger than the outer diameter of.

이러한 구성으로 된 본 고안은 고정받침쇠(5)의 상면으로 융기 돌출되는 접지부(50)가 주철관(2)에 직교되고, 접지부(50)의 선단(51)이 조립부(10)측으로 향하게 하고 완만한 경사기울기를 이루는 면(52)은 조립부(10)와 반대쪽에 위치하도록 조립한다.The present invention having such a configuration has a ground portion 50 which protrudes upward from the upper surface of the fixed support 5 is orthogonal to the cast iron pipe 2, and the front end 51 of the ground portion 50 moves toward the assembly portion 10 side. Face 52 which faces the slope and forms a gentle slope is assembled so as to be located opposite to the assembly portion 10.

그리하면 주철관(2) 고정을 위해 이탈방지 압륜(4)에 부설되는 체결볼트(6)를 시계방향으로 회전시킴에 따라 체결볼트(6)의 끝단에 조립되는 고정받침쇠(5)는 조립부(10)에 끼워지는 주철관(2)의 외주면과 접촉되게 된다.Then, the fixing bracket (5) is assembled to the end of the fastening bolt (6) by rotating the fastening bolt (6) attached to the release preventing pressure ring (4) for fixing the cast iron pipe (2) to the assembly portion It comes into contact with the outer circumferential surface of the cast iron pipe 2 fitted into the (10).

한편, 주철관(2)을 가압하는 고정받침쇠(5)를 긴밀하게 접촉시키기 위해 체결볼트(6)의 체결력을 점진적으로 증가시키면 고정받침쇠(5)에 가내지는 압력이 점차 증대됨에 따라 고정받침쇠(5)의 접지부(50) 선단(51)은 편심된 쪽 즉, 조립부(10)쪽으로 치우치며 약 3°~5°정도 비스듬하게 경사기울기를 가지게 된다. 이때 체결볼트(6)에 의해 고정받침쇠(5)에 가해지는 체결력은 주철관(2)과 접촉되는 접지면(55) 선단(51)에서 비스듬하게 작용하게 되어 주철관(2)은 조립부(10)측으로 밀리게 된다.Meanwhile, if the fastening force of the fastening bolt 6 is gradually increased in order to closely contact the fastening clamp 5 that presses the cast iron pipe 2, the pressure applied to the fastening clamp 5 gradually increases, and thus it is fixed. The tip portion 51 of the ground portion 50 of the iron 5 is biased toward the eccentric side, that is, the assembly portion 10, and has an inclined slope about 3 ° to 5 °. At this time, the fastening force applied to the fixing support 5 by the fastening bolt 6 acts obliquely at the tip 51 of the ground plane 55 in contact with the cast iron pipe 2 so that the cast iron pipe 2 is assembled to the assembly portion 10. Is pushed to the side.

따라서 주철관(1)과 주철관(2)을 연결하는 과정에서 형성되었던 틈새(C)는 주철관(2)이 조립되는 조립부(10)측으로 이동함에 따라 점차적으로 줄어지게 되어 조립되는 조립부(10)측으로 이동함에 따라 점차적으로 줄어지게 되어 조립되는 주철관(1)과 주철관(2) 사이의 틈새(C)를 최소화하게 되어 누수방지에 만전을 기할 수 있는 장점이 있다.Accordingly, the gap C formed in the process of connecting the cast iron pipe 1 and the cast iron pipe 2 gradually decreases as the cast iron pipe 2 moves to the assembly part 10 on which the assembly part 10 is assembled. As it moves to the side is gradually reduced to minimize the gap (C) between the cast iron pipe (1) and the cast iron pipe (2) to be assembled has the advantage that can be made to prevent leakage.

또한 주철관(2)에 가해지는 압력은 주철관(2)과 직교되지 아니하고 조립부(10)측으로 약간 비스듬하게 작용되므로 외부에서 충격이 가해지더라도 주철관이 쉽게 이탈되는 것을 방지하게 된다.In addition, since the pressure applied to the cast iron pipe 2 is not orthogonal to the cast iron pipe 2 and slightly obliquely acts toward the assembly portion 10, the cast iron pipe is prevented from being easily released even when an impact is applied from the outside.

이상에서 설명한 바와 같이 본 고안은 상수도용 주철관을 연결함에 있어, 주철관과 접촉되는 고정받침쇠의 접지면과 체결력을 증대시키고, 고정받침쇠에 가해지는 체결력이 주철관 조립부 측으로 향하게 함으로써 외부에서 충격이 가해지더라도 주철관이 쉽게 이탈되는 것을 방지하는 등의 작용 효과를 가지고 매우 유용한 고안인 것이다.As described above, the present invention, in connecting the cast iron pipe for water supply, increases the clamping force with the ground surface of the fixed support which is in contact with the cast iron pipe, the impact force from the outside by directing the fastening force applied to the fixed support to the cast iron pipe assembly side. Even if it is added, it is a very useful design with the effect of preventing the cast iron pipe is easily separated.
