본 발명은 실린더형 신축이음장치에 관한 것으로써 상세하게는 수도관 및 오폐수관등 각종관이 매설되거나 실,내외등 지면으로 노출된 관들에 지반이 침하되거나 또는 지진등 각종 외력에 의해 관에 영향력이 가해질 경우, 서로 연결된 관이 이탈되는 것을 방지할 수 있도록 한 것이다.The present invention relates to a cylindrical expansion joint device, and in detail, various pipes such as water pipes and wastewater pipes are buried or the ground is subsided to pipes exposed to the ground, such as inside and outside of the room, or the ground is influenced by various external forces such as earthquakes. In this case, the pipes connected to each other can be prevented from coming off.

일반적으로 수도관 및 오수관등의 관은 지반을 굴삭하고 지중에 매설하여 시공하며 송유관, 가스관, 전선관및 실내외 배관등 외부로 노출되어 시공되는 것이 일반적이다.In general, pipes such as water pipes and sewage pipes are excavated and buried in the ground, and are generally exposed to the outside such as oil pipelines, gas pipes, conduits, and indoor and outdoor piping.

이때 매설 및 설치된 각종 관들은 각 기능에 따라서 그 밀봉상태를 양호하게 유지해야 한다.At this time, the buried and installed various pipes should maintain their sealed state according to each function.

그러나, 매설 및 설치되는 관을 연결하기 위하여는 일반적으로 각각의 관의 끝단을 용접하여 결합시키거나 또는 프랜지를 이용하여 볼트로 결합하여 연결하여 사용하는 것이 일반적이다.However, in order to connect the buried and installed pipes, it is common to use the ends of the respective pipes by welding them together or by connecting them by bolts using flanges.

상기와 같이 관을 용접이나 프랜지를 이용하여 연결된 관을 매설하면 지반위에서 하중이 가해질 경우 관이 하중에 의하여 아래로 밀려 변형되고 이렇게 되면 관의 연결부 및 프랜지 부분에 틈이 벌어지게되어 물이나 오수등이 외부로 누설되며 심지어 지진이나 지반의 약화로 인한 지반침하 및 지반의 흔들림으로 인하여 관이 파손되거나 이탈등의 문제점이 발생되며 이러한 문제점의 대비는 현재까지 대책이 없는 심각한 문제점으로 나타나고 있다.If you bury the pipe connected by welding or flange as above, if the load is applied on the ground, the pipe is pushed down by the load and deformed. When this happens, the gap between the connection part and the flange part of the pipe is opened. This leaks to the outside, even ground sedimentation and ground shake due to earthquake or ground weakening cause problems such as tube breakage or separation, and the preparation of these problems is a serious problem without countermeasure until now.

또한, 지상으로 관을 형성하여도 관의 하중은 매설시와 동일하게 발생되여 매설시와 같은 문제점이 발생된다. In addition, even if the pipe is formed on the ground, the load of the pipe is generated in the same way as when buried, the same problem occurs when buried.

따라서 본 발명은 상기의 문제점을 해소하기 위하여 안출한 것으로써 본 발명의 목적은 지중으로 매설되거나 지상으로 설치되는 각종관의 지반침하등의 원인으로 변형되어 파손되는 것을 방지하기 위하여 외관과 이 외관의 내측으로 삽입되는 내관으로 형성되며 각각의 관의 끝단으로 고정용링이 형성된 연질합성수지재질 의 신축관을 일체로 형성시키고 상기 내관의 외주면에 여러개의 오링을 형성하여 외관의 내측과 밀착되겨 형성하여 이 오링이 외관의 내벽면을 미끄럼 이동하게 함으로써 지반의 침하나 지진등에 의한 관의 흔들림에도 관이 파손되거나 이탈하지 않도록 형성한 실린더형 신축이음장치를 제공하는데 있다.Therefore, the present invention has been made in order to solve the above problems, the object of the present invention is to prevent the appearance and deformation of the various pipes buried in the ground or ground to prevent damage caused by deformation, etc. It is formed by the inner tube inserted into the inner tube formed of a flexible tube of flexible resin material with a fixing ring formed at the end of each tube integrally and formed a plurality of O-rings on the outer peripheral surface of the inner tube to form a close contact with the inner side of the outer ring It is to provide a cylindrical expansion joint device formed by sliding the inner wall surface of the exterior so that the tube is not broken or detached even when the ground shakes or the earthquake shakes the tube.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 실린더형 신축이음장치의 특징은, 일측으로 연질합성수지 재질의 신축관이 결합되며 이 신축관의 타측에 고정용링이 일체로 결합되여 형성되며 어느한 부분으로 윤활유주입공이 형성된 외관과; 이 외관의 내측으로 삽입되어 외관의 일측으로 형성된 고정용링에 외부면이 밀착되게 형성되며 중앙으로 여러개의 오링이 결합되고 일측으로 연질합성수지재질의 신축관이 일체로 형성되며 이 신축관의 타측으로 상기 외관의 내면에 밀착되는 고정용링이 형성되여 지반의 침하등에 의하여 관이 변형되는 것을 방지하는 것에 있다.Characteristic of the cylindrical expansion joint device according to the present invention for achieving the above object, the expansion pipe is made of soft synthetic resin material is coupled to one side and the fixing ring is formed integrally coupled to the other side of the expansion pipe formed of any one part The appearance and the lubricant oil injection hole is formed; The outer surface is formed in close contact with the fixing ring formed into one side of the exterior and is formed in one side of the exterior, and a plurality of O-rings are coupled to the center, and one side of the flexible tube is made of a flexible synthetic resin material.
