본 발명은 상수도 곡선관의 이탈 방지 장치에 관한 것으로서, 보다 상세하게 는 지중에 상수도관을 설치하여 물을 공급할 때 물의 수압으로 인해 상수도관을 연결하고 있는 곡선관이 분리 또는 파손되는 것을 방지할 수 있는 상수도 곡선관의 이탈 방지 장치에 관한 것이다.The present invention relates to a device for preventing the separation of a water supply curve, and more particularly, to install a water supply pipe in the ground to prevent water from being separated or broken due to the water pressure of the water supply pipe. The present invention relates to a device for preventing departure of a tap water pipe.

일반적으로, 도시등에서 각 가정으로 상수도를 공급하기 위해서는 땅속(지중)에 각 가정으로 연결되는 상수도관을 설치하여 수돗물을 공급하게 된다.In general, in order to supply water to each household in a city or the like, tap water is provided by installing a water pipe connected to each household in the ground (underground).

상기한 상수도관은 통상적으로 시멘트로 원통형 제작된 것을 사용하거나 또는 금속관을 제작된 것을 사용하게 되는 바, 이를 지면에서 일정 깊이로 판 땅속으로 묻어서 설치하게 된다.In general, the water pipe is made of a cylindrical cylindrical cement or using a metal pipe, which is buried in the ground to a certain depth from the ground to be installed.

즉, 도3에 도시된 바와 같이 직선상으로 제작된 상수도관(50)을 지중에 매설하다가 곡선관(51)을 매설해야 할 위치가 되면 땅을 곡선관(51)에 맞춰서 판 후, 곡선관(51)의 일측을 상수도관(50)에 끼워서 배치하고, 다시 곡선관(51)의 타측에 상수도관(50)을 끼워서 결합시킴과 아울러 이를 흙(M)으로 묻게 되는 것이다.That is, as shown in FIG. 3, when the water supply pipe 50 manufactured in a straight line is buried in the ground, and the ground pipe 51 is in a position to be buried, the ground is aligned with the curved pipe 51, and then the curved pipe One side of the 51 is inserted into the water supply pipe 50, and the water supply pipe 50 is coupled to the other side of the curved pipe 51 to be combined with the soil (M).

물론, 상기한 상수도관(50)과 곡선관(51)과의 연결 부분은 서로 끼워져 있는 상태로서, 물이 새지 않도록 별도의 실링 부재(미 도시)로 마감 처리하게 된다.Of course, the connection portion between the water supply pipe 50 and the curved pipe 51 is fitted with each other, and is finished with a separate sealing member (not shown) so that water does not leak.

그러나, 상기한 바와 같이 상수도관을 매설할 때 직선 형태인 상수도관과 곡면인 곡선관을 서로 끼움 결합시켜 연결하고 이를 흙으로 묻어서 매설하게 되면, 상기한 상수도관으로 공급되는 상수의 압력에 의해 곡선관이 밀리면서 위치가 변경되고 이로 인해 상수도관과 곡선관의 사이를 통해 물이 누수되는 문제점이 있다.However, when embedding the water supply pipes as described above, when the water pipes in a straight form and the curved pipes are connected to each other by fitting them together and buried them in soil, embedded in the water pipes, the curve by the pressure of the constant water supplied to the water pipes As the pipe is pushed, the position is changed, which causes water leakage between the water supply pipe and the curved pipe.

즉, 직선 형태인 상수도관을 타고 흐르는 물이 곡선관에 도달되면 곡선관에 압력을 가하게 됨으로써, 흙으로 지지된 곡선관이 밀리면서 상수도관과 곡선관의 사이에 유격이 발생되고 이 부분을 통해 누수가 발생되는 것이다.In other words, when water flowing in a straight water pipe reaches the curved pipe, pressure is applied to the curved pipe, so that the clearance between the water pipe and the curved pipe is generated while the curved pipe supported by the soil is pushed. Leakage occurs.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 곡선관에 상수의 압력이 인가되어도 곡선관이 밀리면서 위치 변동되지 않도록 함으로써 곡선관에서의 누수 현상을 방지할 수 있는 상수도 곡선관의 이탈 방지 장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and even if a constant pressure is applied to the curved tube, the curved tube is prevented from being leaked by the position of the curved tube, thereby preventing a leak in the curved tube. It is to provide a departure prevention device.

특히, 상기한 고정봉(1)은 "I" 자 형강을 사용하는 바, 상기한 형강의 흙에 매립되었을 때 접촉하는 표면적이 커서 고정력이 매우 강하기 때문에 사용하는 것인 바, 흙에 매립되었을 때 고정력이 강한 형태의 강재를 사용하면 동일한 효과를 얻을 수 있게 된다.In particular, the fixed bar (1) is used because the "I" shaped bar, because the surface area in contact with the buried in the soil of the above-mentioned steel is very large and the fixing force is used, when embedded in the soil The same effect can be obtained by using steel of strong fixing type.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 작업자가 땅을 파고 상수도관(50)과 곡선관(51)이 매립되도록 한 후, 상수도관(50)과 곡선관(51)을 끼움 결합시키면서 땅(M)에 묻게 된다.When explaining the operation and effect of the present invention as described above, the worker digging the ground and the water supply pipe 50 and the curved pipe 51 is buried, while the water supply pipe 50 and the curved pipe 51 while fitting the ground (M) is asked.

이때, 상기한 곡선관(51)이 매립되는 위치의 측면 땅속에는 길게 형성된 고정봉(1)이 매립되어 있는 바, 상기한 고정봉(1)에는 곡선관(51)의 위치에 맞춰서 고정브라켓(7)에 볼트(5)로 고정되어 있게 된다.At this time, the fixed bar (1) formed long in the side ground in the position where the curved tube 51 is embedded, the fixed bar (1) in accordance with the position of the curved tube 51 is fixed to the fixing bracket ( 7) is fixed to the bolt (5).

곡선관(51)이 매립되면 고정 브라켓(7)과의 위치를 조절하여 곡선관(51)을 흐르는 물에 의해 밀리는 방향을 지지하도록 고정 브라켓(7)을 배치한 후, 상기한 곡선관(51)에 결속부재(4)를 밀착시키게 된다.When the curved tube 51 is embedded, the fixed bracket 7 is disposed to support the direction in which the curved tube 51 is pushed by the flowing water by adjusting the position with the fixed bracket 7, and then the curved tube 51 described above. The binding member 4 in close contact.

결속부재(4)를 밀착시킨 후 와이어(2)를 곡선관(51)에 감아서 결속부재(4)에 설치되어 있는 고리(3)에 이를 고정하여 곡선관(51)에 결속부재(4)를 견고하게 고정시키게 된다.After the binding member 4 is in close contact, the wire 2 is wound around the curved tube 51 to be fixed to the ring 3 installed in the binding member 4 to bind the binding member 4 to the curved tube 51. It will be fixed firmly.

이 상태에서는 결속부재(4)에 돌출 형성된 제2나사부(8)와, 고정브라켓(7)에 돌출 형성된 제1나사부(6)가 일직선상을 이루도록 위치되는 바, 상기한 제1, 2나사부(6, 8)에 결합링 부재(9)를 나사 결합시키게 된다.In this state, the second screw portion 8 protruding from the binding member 4 and the first screw portion 6 protruding from the fixing bracket 7 are positioned to form a straight line. 6, 8 to screw the coupling ring member (9).

결합링부재(9)가 제1, 2나사부(6, 8)에 결합되면, 상기한 결합링부재(9)는 일측이 왼나사로 결합되고, 타측이 오른나사로 결합된 것으로서, 결합링 부재(9)를 회전시키게 되면, 제1, 2나사부(6, 8)가 서로 가까워지거나 멀어지게 된다.When the coupling ring member 9 is coupled to the first and second screw portions 6 and 8, the coupling ring member 9 is coupled to one side by a left screw and the other side by a right screw, and the coupling ring member 9. 1), the first and second screw portions 6 and 8 come closer or farther from each other.

제1, 2나사부(6, 8)가 결합링부재(9)에 의해 가까워지거나 멀어지게 되면, 결과적으로 고정봉(1)과 곡선관(51)의 거리가 조절되는 것으로서, 상기한 결합링 부재(9)를 회전시켜 제1, 2나사부(6, 8)가 멀어지도록 하면 결속부재(4)가 곡선관(51)을 견고하게 지지하게 되는 것이다.When the first and second screw portions 6 and 8 come closer or further away from each other by the coupling ring member 9, the distance between the fixed rod 1 and the curved tube 51 is adjusted as a result. Rotating (9) causes the first and second screw portions 6 and 8 to move away from the binding member 4 so as to firmly support the curved tube 51.

즉, 고정봉(1)은 매립되어 견고하게 고정되어 있는 상태이기 때문에, 상기한 결합링부재(9)를 회전시키면 고정봉(고정브라켓)(1)은 고정된 상태에서 결속부재(4)가 이동하면서 곡선관(51)에 견고하게 밀착되는 바, 상기한 결속부재(4)의 밀착에 의해 곡선관(51)이 견고하게 지지되는 것이다.That is, since the fixing rod 1 is embedded and firmly fixed, when the coupling ring member 9 is rotated, the fixing member 4 is fixed in the fixed rod (fixing bracket) 1 state. Bars are firmly adhered to the curved tube 51 while moving, and the curved tube 51 is firmly supported by the close contact of the binding member 4.

곡선관(51)이 결속부재(4)에 의해 견고하게 지지되면, 상기한 곡선관(51)과 상수도관(50)의 결합이 매우 견고하게 유지될 수 있게 된다.If the curved tube 51 is firmly supported by the binding member 4, the combination of the curved tube 51 and the water supply pipe 50 can be maintained very firmly.

특히, 상수도관(50)으로 물이 유입되어 곡선관(51)에 압력을 가해도 곡선관 (51)을 매립한 흙의 지지력 및 상기한 결속부재(4)의 지지력에 의해 곡선관(51)이 유동하지 않게 되고, 이로 인해 곡선관(51)과 상수도관(50)의 연결 부분에서 누수가 발생되는 것을 방지할 수 있게 되는 것이다.In particular, even if water flows into the water supply pipe 50 and applies pressure to the curved pipe 51, the curved pipe 51 is supported by the bearing force of the soil in which the curved pipe 51 is embedded and the holding force of the binding member 4 described above. This flow does not flow, and thus it is possible to prevent the leakage occurs in the connection portion of the curved tube 51 and the water supply pipe 50.

이상과 같이 본 발명은 땅속에 상수도관과 곡선관의 매립 시 곡선관의 측면을 지지하도록 결속부재를 설치하고, 상기한 결속부재가 고정봉에 지지되도록 함으로써, 곡선관이 물의 압력에 의해 유동하지 않도록 하고 상수도관과 사이에 유격이 발생되지 않도록 함으로써, 물이 누수되는 것을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention provides a binding member so as to support the side surface of the curved tube when the water supply pipe and the curved tube are buried in the ground, and the binding member is supported by the fixing rod, so that the curved tube does not flow under the pressure of water.
