This pipe connection part can not withstand the pressure of the tap water to be reinforced with a clamp, or to prevent it from being separated by a release preventing member therein.

이와 같이 상,하수도관의 연결부위를 보강 연결하기 위한 선행기술에는 등록특허 10-0905299호(발명의 명칭 : 수도관 연결용 클램프), 등록특허 10-1279933호(발명의 명칭 : 합성수지관용 클램프) 및 공개특허 10-2017-0082268호(발명의 명칭 : 수도관 연결용 클램프)가 제공되고 있다.Thus, prior art for reinforcing connection of the connection part of the water and sewage pipes are registered Patent No. 10-0905299 (name of invention: clamp for water pipe connection), Patent No. 10-1279933 (name of invention: clamp for synthetic resin pipe) and Patent Publication No. 10-2017-0082268 (name of the invention: a clamp for connecting a water pipe) is provided.

이와 같은 선행기술의 수도관 연결용 클램프는 합성수지관으로 이루어진 제1,2관을 연결하기 위하여 형성된 확관부에 가해지는 고압의 수압을 충분히 견딜 수 있도록 클램프를 구성하여 강도가 약해진 확관부를 구성하는 제1,2확관부 사이의 제1단턱부에 대한 강도를 보강시키게 되었으며, 또한 지지편과 지지대로써 2중으로 클램프 자체의 강도를 보강시켜 제1,2관의 연결부위를 안정되게 고정함에 따라 클램프 자체 변형이 방지되고, 제1,2관의 이탈이 방지되어 원활한 물공급을 할 수 있는 효과가 제공된다.Such a prior art water pipe connection clamp comprises a clamp configured to sufficiently endure the high pressure of the water pressure applied to the expansion pipe formed to connect the first and second pipes made of a synthetic resin pipe to form a weakened expansion pipe portion. The strength of the first step between the 1st and 2nd expansion parts is reinforced, and the clamp itself is secured by stably fixing the connection part of the 1st and 2nd pipes by reinforcing the strength of the clamp itself by double as the support piece and the support. The deformation is prevented, and the separation of the first and second pipes is prevented, thereby providing an effect of smooth water supply.

그러나 이러한 클램프는 제1관과 제2관의 확관부의 외주면에 제1,2압륜의 협지턱으로써 압착 고정되어 제1,2관의 연결부위를 안정되게 고정됨에 따라 수도라인의 수압에는 충분히 견딜 수 있는 구조이나, 지진 등의 큰 외력에는 제2관의 확관부로부터 제1관이 이탈되는 동시에 제1,2압륜으로부터 이탈되는 문제점을 갖는 것이다.However, these clamps are press-fixed to the outer circumferential surfaces of the expansion pipes of the first and second pipes by the clamping jaws of the first and second pressure rings to stably fix the connection portions of the first and second pipes, thereby sufficiently enduring the hydraulic pressure of the water line. It is possible to have a problem that the first pipe is separated from the expansion pipe of the second pipe and the first and second pressure wheels are separated from the large external force such as a structure or an earthquake.

또한, 선행기술의 합성수지관용 클램프는 편수관 및 일반관에 모두 적용할 수 있으며, 확관부의 종류 및 길이에 상관없이 적용 가능하여, 다양한 종류의 합성수지관에 적용할 수 있는 효과가 제공되는 것이다.
