통상, 마이크로 파일은 지하에 천공된 홀 또는 매설된 관체 등에 길이방향으로 나사선이 형성된 축관을 삽입하고, 상기의 홀 또는 관체에 전송관을 이용하여 콘크리트 몰탈을 주입한 후 일정시간 경화시켜 얻어진다.In general, a micropile is obtained by inserting a shaft tube having a threaded line in a longitudinal direction in a hole or a tube that is underground, and injecting concrete mortar using a transmission tube into the hole or tube, and then hardening it for a predetermined time.
상기와 같은 축관을 철근콘크리트 구조와 철골철근콘크리트 구조에 사용하기 위해서 축관을 서로 이음 해야 하는 경우가 있는데, 이를 위해 축관 단부에 이음구조를 형성한 후, 내주면에 암나사가 형성된 커플러를 통하여 축관의 단부가 서로 연결되도록 되어 있다.In order to use the shaft as described above for the reinforced concrete structure and the steel reinforced concrete structure, the shaft pipes may need to be jointed with each other. For this purpose, after the joint structure is formed at the end of the shaft pipe, the end of the shaft pipe is formed through a coupler having a female thread formed on the inner circumferential surface thereof. Are intended to be connected to each other.
상기와 같은 종래의 축관 이음구조는 커플러의 나사측에 응력이 집중되는 현상이 발생하여 국부적인 커플러 나사선의 파괴 현상이 발생하는 문제점이 있었다.The conventional shaft pipe joint structure has a problem in that stress is concentrated on the screw side of the coupler, so that a breakdown phenomenon of the local coupler thread occurs.
본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 마이크로 파일의 축관 간에 상호 이음 시 축관 단부에 나사선이 형성된 돌출부가 축관의 내경에 체결되도록 구성하여 이음장치인 별도의 커플러 없이 축관 몸체 자체만으로 용이하게 이음할 수 있는 축관 이음구조를 제공함을 목적으로 한다.The present invention was devised to solve the above drawbacks, and when the mutual connection between the shaft of the micro pile, the protrusion formed with a screw thread on the end of the shaft is fastened to the inner diameter of the shaft by the shaft body itself without a separate coupler as a joint device An object of the present invention is to provide a tube joint structure that can be easily joined.
상기 목적을 달성하기 위한 본 고안은 나사선이 길이방향으로 형성된 축관(10)에 있어서,The present invention for achieving the above object in the shaft tube 10 is formed in the longitudinal direction of the thread,
상기 축관(10) 양측 단부에 폭이 점차 좁아지는 돌출부(11)가 형성되고, 상기 돌출부(11)의 외주면에 나사선(11a)이 형성되며, 상기 돌출부(11)의 외경이 타단의 축관(10) 내경에 체결되도록 구성된 것을 요지로 한다.Protruding portions 11 are gradually narrowed at both ends of the shaft tube 10, a threaded line 11a is formed on an outer circumferential surface of the protrusion 11, and an outer diameter of the protrusion 11 is the other end of the shaft tube 10. The main point is to be configured to be fastened to the inner diameter.
