철골 조립용 스크류 클램프{SCREW CLAMP}Screw clamp for steel frame assembly {SCREW CLAMP}

본 고안은 철골 조립용 스크류 클램프에 관한 것으로, 더욱 상세하게는 샤클과 죠우를 분리하여 죠우와 스크루부재 사이에 철판 및 철재빔이 파지되도록 하고, 샤클은 작업 과정에서 좌우로 자유롭게 회전되도록 하여 작업성을 향상시키도록 하는 철골 조립용 스크류 클램프에 관한 것이다.The present invention relates to a screw clamp for assembling steel, and more particularly, to separate the shackle and the jaws so that the steel plate and the steel beam is gripped between the jaws and the screw member, the shackle is rotated to the left and right during the work process workability It relates to a screw clamp for steel assembly to improve the.

일반적으로 철골 조립용 스크류 클램프는 조선, 해양 및 각종 건축 플랜트의 철골 작업시 체인블럭 및 레버블럭의 훅 걸이용으로 사용되는 공구이다.In general, the screw clamp for assembling steel frame is a tool used for hook hook of chain block and lever block during steel frame work of shipbuilding, offshore and various construction plants.

도 1 및 도 2는 종래에 따른 철골 조립용 스크류 클램프의 일예를 나타낸 도면이다.1 and 2 is a view showing an example of a screw clamp for assembling steel according to the prior art.

도시한 바와 같이 철골 조립용 스크류 클램프는 일측에 개구부(1a)가 형성되고, 타측에 파지부(1b)가 형성된 몸체(1)와, 상기 개구부(1a)의 하단부 나사공(1c)에 결합되어 전,후진되고, 외측 단부에 핸들(2a)이 구비된 스크류부재(2)와, 상기 몸체(1)의 개구부(1a) 상측에 관통되게 설치되어 회전가능하고, 상단은 샤클결합공이 형성되며, 하측은 죠우(3a)가 형성되어진 축부재(3)와, 상기 축부재(3)의 외주면에 결합되어진 베어링(4)과, 상기 샤클결합공에 샤클핀(5a)으로 하측이 결합되고, 상측에는 훅이 걸리는 걸이공(5b)이 형성된 샤클(5)로 구성되어 있다.As illustrated, the screw clamp for assembling steel frame is coupled to a body 1 having an opening 1a formed at one side thereof, a gripping portion 1b formed at the other side thereof, and a lower end screw hole 1c of the opening 1a formed therein. Forward and backward, the screw member (2) having a handle (2a) at the outer end, and installed through the opening (1a) upper side of the body (1) is rotatable, the upper end is formed with a shackle coupling hole, The lower side is coupled to the shaft member 3 in which the jaw 3a is formed, the bearing 4 coupled to the outer circumferential surface of the shaft member 3, and the lower side by the shackle pin 5a to the shackle coupling hole. It is comprised by the shackle 5 in which the hook hole 5b which hooks are formed in.

상기와 같은 철골 조립용 스크류 클램프는 샤클(5)의 결합공(5b)에 체인블럭 및 레버블럭의 훅(6)을 결합하고, 상기 개구부(1a)에 철판 또는 철재빔(7)(이하 "부재"라 칭함)을 삽입시킨 상태에서 핸들(2a)을 회전시키게 되면 스크류부재(2)가 전진하여 부재(7)를 파지하게 된다.The screw clamp for assembling the steel frame combines the hook 6 of the chain block and the lever block to the coupling hole 5b of the shackle 5, and the steel plate or the steel beam 7 (hereinafter " When the handle 2a is rotated in the state of inserting the " member ", the screw member 2 advances and the member 7 is gripped.

또한, 상기의 철골 조립용 스크류 클램프의 샤클(5)은 수직 및 수평방향으로 샤클핀(5a)을 중심으로 회전되어 작업이 가능한 것이다.In addition, the shackle 5 of the screw clamp for steel frame assembly is to be rotated about the shackle pin (5a) in the vertical and horizontal directions to work.

그러나, 종래의 철골 조립용 스크류 클램프는 스크류부재(2)와 축부재(3)의 죠우(3a)사이에 부재(7)를 파지한 상태에서 작업의 편리성을 위해 사용 방향(좌,우)으로 회전시킬 수 없으며, 사용 방향으로 회전하게 되면 스크류부재(2)의 나사가 풀리는 현상이 발생하는 문제점이 있다.However, the conventional screw clamp for steel frame assembly uses the direction of use (left and right) for convenience of work in a state where the member 7 is gripped between the screw member 2 and the jaw 3a of the shaft member 3. It can not be rotated, and when rotated in the use direction there is a problem that the screw loosening of the screw member 2 occurs.

또한, 스크류부재(2)와 축부재(3)의 죠우(3a)사이에 부재(7)가 파지되면 베어링(4)이 불필요한 문제점이 있다.In addition, when the member 7 is gripped between the screw member 2 and the jaw 3a of the shaft member 3, there is a problem that the bearing 4 is unnecessary.

즉, 부재(7)가 파지되지 않은 무부하 상태에서는 베어링(4)에 의해 축부재 (3) 및 샤클(5)이 자유자재로 회전 가능하지만, 부재(7)가 철골 조립용 스크류 클램프에 파지되면 고가의 베어링(4)이 필요없게 되는 것이다.That is, in the no-load state in which the member 7 is not gripped, the shaft member 3 and the shackle 5 can be freely rotated by the bearing 4, but the member 7 is gripped by the screw clamp for steel assembly. No expensive bearings 4 are needed.

또한, 수평방향으로 인장작업시 죠우(3a) 끝단부와 샤클(5)의 중심부의 간격(t1)이 넓어(약 81mm) 인장작업중에 부재가 뒤틀림이 발생되는 문제점이 있다.In addition, when the tensioning operation in the horizontal direction, the distance (t1) between the end of the jaw (3a) and the center of the shackle 5 is wide (about 81mm) there is a problem that the member is distorted during the tensioning operation.

본 고안은 이러한 종래의 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 샤클과 죠우를 분리하여 죠우와 스크루부재 사이에 부재가 파지되도록 하고, 샤클은 작업 과정에서 좌우로 자유롭게 회전되도록 하여 작업성을 향상시키도록 하는 잭받침용 지그 철골 조립용 스크류 클램프를 제공함에 있다.The present invention has been made to solve such a conventional problem, the purpose of which is to separate the shackle and the jaw so that the member is gripped between the jaw and the screw member, and the shackle is rotated freely from side to side in the working process to improve workability It is to provide a screw clamp for assembling jig steel frame for jack support.
