Description

송수관용 연결구조{an expansion joint for water pipe }An expansion joint for water pipe}

본 발명은 송수관용 연결구조에 관한 것이다.
The present invention relates to a connection structure for the water pipe.

일반적으로 상수관이나 하수관과 같은 송수관들은 그 길이가 일정하게 형성되고 연속적으로 결합되어 원하는 목적지까지 물을 이송시킬 수 있도록 되어 있으며, 주로 송수관들의 결합부에는 조인트가 장착되어 관들을 서로 연결시킬 수 있도록 되어 있다.In general, water pipes such as water pipes and sewage pipes are formed to have a constant length and are continuously coupled to transport water to a desired destination. The water pipes are mainly equipped with joints so that pipes can be connected to each other. It is.

이와 같은 조인트는 주로 단순하게 양측관들을 결합시킨 것이므로 지반이 침하되거나 송수관 내부에 과도한 수압이 발생되면 조인트에서 양측 관들이 이탈되어 누수가 발생되는 주요 원인이 되었다.Since these joints are mainly a simple combination of both pipes, if the ground subsides or excessive water pressure is generated inside the water pipe, both pipes are separated from the joint, which is a major cause of leakage.

물론, 이러한 문제점을 감안하여 이탈 방지용 조인트가 개발된 것이 있으나, 이와 같은 조인트는 관이 이탈되는 폐단을 줄일 수 있는 반면 관을 과도하게 조여줌에 따라 관이 손상되는 등의 문제점이 있었다.Of course, in view of these problems, there is a joint for preventing the separation has been developed, but such a joint can reduce the closed end of the tube while there is a problem such as damage to the tube by tightening the tube excessively.

따라서, 지반의 침하가 이루어질 때 지하에 매설된 관의 이탈 및 누수 등으로 막대한 예산 낭비가 있었고 이를 위하여 내진을 이룰 수 있는 신축관의 개발이 절실히 요구되었으며, 지진의 위험에 안심할 수 없는 한반도의 실정을 감안하여 신축되는 조인트에 의하여 내진을 목적으로 한 설계를 이루도록 하였다.Therefore, when the ground subsided, there was enormous budget waste due to the separation and leakage of the pipes buried underground, and for this purpose, the development of new pipes that could achieve earthquake was desperately needed. In view of this, expansion and contraction of the joint was designed to achieve the design.

이에, 대한민국 등록특허 제10-0310659호의 "송수관용 신축 조인트장치"가 제안되었다. 도 1은 종래기술의 송수관용 신축 조인트장치를 도시한 분해사시도이다.Thus, the Republic of Korea Patent No. 10-0310659 of "contraction pipe joint device for water pipes" has been proposed. 1 is an exploded perspective view showing a conventional expansion joint device for water pipes.
