TEMPORARY JOINT SUPPORTING DEVICE FOR STEEL PIPE AND BORING METHOD THEREOF
A temporary support apparatus (200) according to the present invention includes: a band portion (210) formed of a non-ferrous metal material that supports the inside of a joining portion (A) to which a plurality of steel pipes (100) is welded and coupled, and is not coupled to the inside of the steel pipe (100) by welding at the time of welding of the joining portion (A); and a detachable portion (220) coupled to an opening portion (211) of the band portion (210) so as to enable a contract operation of closely contacting the band portion (210) to the inside of the steel pipe (100), and a releasing operation of releasing the close contract. The temporary support device (200) of the present invention is not coupled to the inside of the steel pipe by welding but is easily attached and coupled because the band portion (210) is tightly coupled to the inside of the steel pipe by driving the detachable portion (220). Also, since the temporary support device (200) is formed of a non-ferrous metal material, the temporary support device (200) is not coupled to the inside of the steel pipe by welding of the joining portion (A).
본 발명에 의한 임시지지장치(200)는 복수의 강관(100)이 용접결합되는 결합부(A) 내측을 지지하되, 결합부(A)의 용접결합시 용접에 의해 강관(100)의 내측에 결합되지 않는 비철금속 재료로 형성된 밴드부(210); 밴드부(210)를 강관(100) 내측에 밀착시키는 밀착구동과, 밀착을 해제하는 해제구동이 가능하도록 상기 밴드부(210)의 개방부(211)에 결합된 탈착부(220);를 포함한다. 본 발명의 임시지지장치(200)는 용접에 의해 강관 내부에 결합되는 것이 아니라 탈착부(220)의 구동에 의해 밴드부(210)가 강관 내측에 밀착결합하기 때문에 임시지지장치의 설치와 해제가 용이하다. 또한 임시지지장치(200)는 비철금속 재료로 형성되기 때문에 결합부(A) 용접에 의해 강관 내부에 결합되지 않는다.
