이때, 상기 상하수도관(1)의 전후단에는 플랜지부(2)가 형성되어, 상기 플랜지부(2)를 관통하는 볼트(3)에 의해 상호 수밀하게 연결된다.At this time, flange portions 2 are formed at the front and rear ends of the water and sewage pipes 1, and are watertightly connected to each other by bolts 3 penetrating the flange portions 2.

그런데, 이러한 상하수도관(1)은 지진이 발생되면, 상호 연결된 상하수도관(1)이 서로 다른 방향으로 진동되며, 이에 따라, 상하수도관(1)의 연결부위가 손상되어 누수가 발생되는 문제점이 있었다.However, when an earthquake occurs in these water and sewer pipes (1), the interconnected water and sewer pipes (1) vibrate in different directions, and as a result, there was a problem in that the connection portion of the water and sewer pipes (1) was damaged and water leaks occurred. .

따라서, 최근에는 이러한 문제점을 해결하기 위하여, 등록특허 10-1702990호를 비롯한 다수의 선행문건에 나타난 바와 같이, 다양한 형태의 상하수도용 내진설계가 개발되었으나, 이러한 상하수도용 내진설계는 구조가 복잡하고, 상하수도관(1)이 지진에 의해 비틀릴 때 상하수도관(1)의 연결부의가 손상되는 것을 방지하기 어려운 문제점이 발생되었다.Therefore, recently, in order to solve these problems, various types of earthquake-resistant designs for water supply and sewage have been developed, as shown in a number of prior documents, including registered patent No. 10-1702990. However, these earthquake-resistant designs for water and sewage have a complex structure, When the water and sewage pipes (1) are twisted by an earthquake, it is difficult to prevent damage to the connection portion of the water and sewage pipes (1).

상기 전후방 막음판(24,25)은 내경이 상기 상하수도관(1)의 외경에 비해 큰 반원형상으로 구성되어, 상기 상하측 덮개부(21,22)의 전후단에 볼트(26)로 결합된다.The front and rear blocking plates (24, 25) have a semicircular shape with an inner diameter larger than the outer diameter of the water and sewer pipe (1), and are attached to the front and rear ends of the upper and lower cover parts (21, 22) with bolts (26). .

이를 자세히 설명하면, 상기 전방 막음판(24)과 후방막음판은 각각 2개씩으로 구성된다.To explain this in detail, the front blocking plate 24 and the rear blocking plate each consist of two pieces.

그리고, 상기 전방 막음판(24)을 상하측 덮개부(21,22)의 전단부에 결합하면, 상기 전방 막음판(24)은 전방에 위치된 상하수도관(1)의 플랜지부(2)의 전방에 위치되고, 후방 막음판(25)을 상하측 덮개부(21,22)의 후단부에 결합되면, 상기 후방 막음판(25)은 후방에 위치된 상하수도관(1)의 플랜지부(2)의 후방에 위치된다.And, when the front blocking plate 24 is coupled to the front ends of the upper and lower cover parts 21 and 22, the front blocking plate 24 is attached to the flange portion 2 of the water supply and sewage pipe 1 located in the front. It is located in the front, and when the rear blocking plate (25) is coupled to the rear end of the upper and lower cover portions (21 and 22), the rear blocking plate (25) is connected to the flange portion (2) of the water and sewage pipe (1) located at the rear. ) is located behind the

상기 지지볼트(27)는 전방 막음판(24)을 전방에서 후방으로 관통하도록 결합되고, 후방 막음판(25)을 후방에서 전방으로 관통하도록 결합된다.The support bolt 27 is coupled to penetrate the front blocking plate 24 from front to rear, and is coupled to penetrate the rear blocking plate 25 from rear to front.

이때, 상기 지지볼트(27)는 선단부가 상기 상하수도관(1)의 플랜지부(2)에서 미리 설정된 거리만큼 이격되도록 결합된다.At this time, the support bolt 27 is coupled such that its tip is spaced apart from the flange portion 2 of the water supply and sewage pipe 1 by a preset distance.

따라서, 지진에 의해 상하수도관(1)이 서로 반대방향으로 진동하면서 이격되어 상기 탄성관체(10)를 길이가 늘어나는 방향으로 당기게 될 경우, 상하수도관(1)의 플랜지부(2)가 상기 지지볼트(27)의 선단부에 걸려 더 이상 이격되지 않도록 고정하게 된다.Therefore, when the water supply and sewage pipes (1) are separated while vibrating in opposite directions due to an earthquake and the elastic pipe body (10) is pulled in the direction of increasing length, the flange portion (2) of the water supply and sewage pipe (1) is connected to the support bolt. It is caught on the tip of (27) and fixed so that it is no longer separated.

상기 압축코일스프링(28)은 상기 지지볼트(27)의 외측에 위치되도록 결합되어, 전후방 막음판(24,25)을 외측, 즉, 전후방향으로 밀어냄으로써, 상기 전후방 막음판(24,25)에 결합된 지지볼트(27)의 선단부가 상하수도관(1)의 플랜지로부터 동일한 간격만큼 이격되도록 지지하는 기능을 한다.The compression coil spring 28 is coupled to be located on the outside of the support bolt 27, and pushes the front and rear blocking plates 24 and 25 outward, that is, in the front and rear direction, thereby closing the front and rear blocking plates 24 and 25. The tip of the support bolt 27 coupled to functions to support the flange of the water supply and sewage pipe 1 to be spaced at the same distance apart.

따라서, 도 8에 도시한 바와 같이, 지면에 상기 상하수도관(1)을 매립하기 위한 도랑(5)을 굴착하고, 상기 도랑(5)의 중간부에 상기 맨홀(30)을 매립한 후, 도 9에 도시한 바와 같이, 상기 상하수도관(1)의 단부가 상기 맨홀(30)의 관통공(31)을 통해 맨홀(30)의 내부에 위치되도록 배치하고, 도 10에 도시한 바와 같이, 상기 탄성관체(10)를 상하수도관(1)의 인접단에 나사결합함으로써, 상하수도관(1)을 연결할 수 있다.Therefore, as shown in FIG. 8, after excavating a trench 5 for burying the water supply and sewage pipe 1 in the ground and burying the manhole 30 in the middle of the trench 5, As shown in Figure 9, the end of the water supply and sewage pipe 1 is arranged to be located inside the manhole 30 through the through hole 31 of the manhole 30, and as shown in Figure 10, the The water and sewage pipes (1) can be connected by screwing the elastic tubular body (10) to the adjacent end of the water and sewage pipes (1).

그리고, 도 11에 도시한 바와 같이, 상기 상하수도관(1)의 연결부의 외측에 상기 고정관체(20)를 결합하고, 상기 도랑(5)을 매립함으로써, 상하수도관(1)의 매립을 완료할 수 있다.And, as shown in FIG. 11, the embedding of the water supply and sewage pipe (1) can be completed by coupling the fixing pipe body (20) to the outside of the connection part of the water supply and sewage pipe (1) and filling the trench (5). You can.

이와 같은 상하수도관의 내진구조에 따르면, 상기 상하수도관(1)이 탄성관체(10)에 의해 상호 연결됨으로, 지진이 발생되어 상하수도관(1)이 서로 다르게 진동되더라도 탄성관체(10)가 적절히 변형되면서 상하수도관(1)을 상호 수밀하게 연결하며, 상하수도관(1)의 연결부위가 손상되어 누수가 발생되는 것을 방지할 수 있는 장점이 있다.According to this earthquake-resistant structure of water and sewage pipes, the water and sewage pipes (1) are connected to each other by the elastic pipe body (10), so that even if an earthquake occurs and the water and sewer pipes (1) vibrate differently, the elastic pipe body (10) is appropriately deformed. This has the advantage of connecting the water and sewage pipes (1) watertightly to each other and preventing water leakage from occurring due to damage to the connection part of the water and sewage pipes (1).

또한, 상기 상하수도관(1)의 연결부의 외측에는 상하수도관(1)이 미리 설정된 거리 이상으로 이격되지 않도록 고정하는 고정관체(20)가 구비됨으로, 지진에 의해 상하수도관(1)이 이격되어 탄성관체(10)를 과도하게 잡아당겨, 탄성관체(10)가 손상되는 것을 방지할 수 있는 장점이 있다.In addition, a fixing pipe body 20 is provided on the outside of the connection part of the water and sewage pipes 1 to prevent the water and sewage pipes 1 from being spaced apart by more than a preset distance, so that the water and sewage pipes 1 are separated by an earthquake and become elastic. There is an advantage in preventing the elastic tube body 10 from being damaged by excessively pulling the tube body 10.
