강관의 결합구조{COUPLING STRUCTURE OF STEEL PIPES}COUPLING STRUCTURE OF STEEL PIPES}

본 발명은 수도용 혹은 일반 산업용 강관의 결합구조에 관한 것으로, 제1강관과 제2강관을 연이어 결합하는 강관의 결합구조에 있어서, 상기 제1강관의 후단부에 확관부를 형성하고, 상기 확관부를 관통하여 상부에 토출밸브를 갖춘 토출구, 하부에 주입밸브를 갖춘 주입구를 각 장착하며, 상기 제1강관의 확관부와 상기 제2강관의 선단부의 사이에 완충성의 패킹을 장착하고, 상기 제1강관의 확관부와 상기 제2강관의 선단부 및 상기 패킹의 사이에 접착제를 충진하여 완성하는 것을 특징으로 한다.The present invention relates to a coupling structure of steel pipes for water or general industrial use, in a coupling structure of steel pipes that connects a first steel pipe and a second steel pipe successively, wherein an expansion pipe portion is formed at a rear end of the first steel pipe, and the expansion pipe portion A through hole is provided with an outlet having a discharge valve in the upper portion and an inlet having an injection valve in the lower portion, and a cushioning packing is installed between the expansion portion of the first steel pipe and the tip portion of the second steel pipe, Characterized by filling the adhesive between the expansion portion of the steel pipe and the distal end of the second steel pipe and the packing is characterized in that completed.

상기 본 발명의 강관의 결합구조에 따르면, 제1강관과 제2강관을 연이어 결합함에 있어, 제1강관을 소켓형으로 구성하고, 후속되는 제2강관의 외주면에 완충성의 패킹을 끼워 접속한 후, 내부에 접착제를 충진하여 강관을 접합함으로써, 각 강관을 접속할 때 마다 현장에서 직접 용접하던 기존의 방식에 비해 공기를 단축할 수 있으며, 지반의 처짐이나 변형에 능동적으로 대처할 수 있어 매우 효과적이다.According to the coupling structure of the steel pipe of the present invention, in the subsequent coupling of the first steel pipe and the second steel pipe, the first steel pipe is configured in a socket shape, and after connecting the cushioning packing to the outer peripheral surface of the subsequent second steel pipe By joining the steel pipes by filling the adhesive inside, it is possible to shorten the air compared to the conventional method of directly welding in the field every time each steel pipe is connected, and it is very effective because it can cope actively with the deflection or deformation of the ground.

일반적으로 수도용 혹은 일반 산업용 강관을 접합하는 방법은, 공사 현장에서 지반을 파 헤친 다음 강관을 부설하고, 발전기를 가동하여 이음(접속)작업을 하되, 주로 용접작업을 통하여 접속시키고 있다.In general, a method of joining steel pipes for water or general industrial use is made by digging the ground at a construction site, then laying steel pipes, and running a generator to connect the joints.

그런데, 이러한 기존의 용접 작업에 의한 접합방법은, 공사현장에서 직접 용접 작업을 시행하여야 하므로 작업 환경이 좋지 않고, 공사기간과 공사비용이 과다하게 소요될 수 있다.By the way, the conventional welding method by the welding work, because the welding work must be carried out directly at the construction site, the working environment is not good, the construction period and the construction cost may be excessive.

또한, 인구가 밀집해 있는 도심지 등에서는, 용접작업으로 인한 안전사고의 예방에 주의하여야 함은 물론, 장기간에 걸쳐 공사를 하여야 하므로 이로 인한 보행자나 차량의 통행에 상당한 불편이 뒤따르게 마련이고.In urban areas with a high concentration of population, attention must be paid to the prevention of safety accidents due to welding work, and construction must be carried out over a long period of time, which leads to considerable inconvenience in traffic for pedestrians and vehicles.

또한, 상기 용접작업에 의하여 강관을 일단 접속한 후에는, 설치구간을 곡선으로 수정하는 경우 등의 갑작스런 지형의 변화에 즉시 대응할 수 없고, 지반의 처짐이나 변형에도 능동적으로 대처할 수 없었다.In addition, once the steel pipe is connected by the welding operation, it is not possible to immediately cope with the sudden change of the terrain, such as when the installation section is corrected by a curve, and actively copes with the deflection or deformation of the ground.

따라서, 본 발명에서는 상기 종래의 문제점을 개선한 것으로, 본 발명의 목적은, 제1강관과 제2강관을 연이어 결합하는 강관의 결합구조에 있어서, 상기 제1강관의 후단부에 확관부를 형성하고, 상기 확관부를 관통하여 상부에 토출밸브를 갖춘 토출구, 하부에 주입밸브를 갖춘 주입구를 각 장착하며, 상기 제1강관의 확관부와 상기 제2강관의 선단부의 사이에 완충성의 패킹을 장착하고, 상기 제1강관의 확관부와 상기 제2강관의 선단부 및 상기 패킹의 사이에 접착제를 충진하여 완성함으로써,Accordingly, the present invention improves the conventional problems, and an object of the present invention, in the coupling structure of the steel pipe to connect the first steel pipe and the second steel pipe in succession, the expansion pipe portion is formed at the rear end of the first steel pipe And through each of the expansion pipes, a discharge port having a discharge valve in the upper portion and an injection hole having an injection valve in the lower portion are mounted, and a cushioning packing is installed between the expansion portion of the first steel pipe and the distal end of the second steel pipe. By filling an adhesive between the expansion pipe portion of the first steel pipe and the tip portion of the second steel pipe and the packing,

제1강관과 제2강관을 연이어 결합함에 있어, 제1강관을 소켓형으로 구성하고, 후속되는 제2강관의 외주면에 완충성의 패킹을 끼워 접속한 후, 내부에 접착제를 충진하여 강관을 접합하여, 각 강관을 접속할 때 마다 현장에서 직접 용접하던 기존의 방식에 비해 공기를 단축할 수 있으며, 지반의 처짐이나 변형에 능동적으로 대처할 수 있는 새로운 형상의 수도용 혹은 일반 산업용 강관의 결합구조를 제공하고자 한다.In joining the first steel pipe and the second steel pipe in series, the first steel pipe is configured in a socket shape, and the buffer packing is connected to the outer circumferential surface of the second steel pipe, followed by filling the adhesive therein to bond the steel pipe. When connecting each steel pipe, we can shorten the air compared to the existing method of directly welding in the field, and provide a new structure of water pipe or general industrial steel pipe that can actively cope with the deflection or deformation of the ground. .
