본 고안은 주로 건물의 신축시 골조로 사용될 철근이나 또는 건물의 철거작업시 발생된 철근골조를 절단해 주도록 한 철근절단장치에 관한 것으로서 특히 휴대와 취급이 용이하고 작업이 신속하게 이루어질 수 있도록 함을 목적으로 한 것이다.The present invention mainly relates to a rebar cutting device for cutting reinforcing bars to be used as a frame for new construction of buildings or reinforcing frames generated during the demolition work of buildings. It is for the purpose.

종래에는 건물의 신축시 골조로 사용될 철근이나 또는 건물의 철거작업시 건물의 골조를 이루고 있던 철근의 절단작업이 산소용접기의 강한 불꽃에 의해 이루어지도록 하고 있다.In the related art, cutting of reinforcing bars which are used as a frame when a building is being constructed or when reinforcing bars which are a frame of a building when a building is removed is performed by a strong flame of an oxygen welding machine.

따라서 산소용접기를 사용하기 위하여는 비교적 무겁고 부피가 큰 산소통과 LPG통을 필요로 하게 되므로 취급과 이동이 매우 불편하고 힘이 들게 되며, 또한 산소통과 LPG통은 사용후 재충전을 필요로 하게 되므로 재충전시 비용이 많이 소요됨은 물론 특히 작업장이 고층 건물인 경우에는 이 산소통과 LPG통을 옮겨 주는데만도 많은 인력과 시간이 소요되고 항상 화재나 폭발의 위험이 상존하게 되므로 사용하기가 여간 조심스러운 일이 아닐 수 없는 등의 문제점이 있는 것이었다.Therefore, in order to use an oxygen welding machine, a relatively heavy and bulky oxygen cylinder and an LPG cylinder are required, so handling and movement are very inconvenient and laborious. Not only is it expensive, but especially in the case of high-rise buildings, it takes a lot of manpower and time to move the oxygen and LPG tanks, and there is always a risk of fire or explosion. There was a problem such as not.

본 고안은 상기한 바와 같은 제반 문제점을 해결하기 위하여 유압잭(JACK)의 작동봉에 절단날을 연결 형성하여 고정판으로 부터 연결 형성된 고정날을 절단날과 마주보게 설치해 주므로서 전동기와 연결 설치된 편심축의 작동간에 의해 유압잭을 작동시켜 주게 되면 절단날이 전진하여 절단날과 고정날 사이의 철근을 절단시켜 주도록 구성한 것으로서 본 고안의 실시도면을 토대로 보다 상세히 설명하기로 한다.The present invention connects the cutting blade to the operating rod of the hydraulic jack (JACK) in order to solve the problems described above by installing the fixed blade connected to the cutting blade formed from the fixed plate facing the cutting blade operation of the eccentric shaft installed When the hydraulic jack is operated by the liver, the cutting blade is advanced to be configured to cut the reinforcing bar between the cutting blade and the fixed blade, and will be described in more detail based on the embodiment of the present invention.

미설명부호Unexplained code

(62)는 파지부62, the grip

(64)는 철근이다.64 is the rebar.

이와 같이 구성된 본 고안은 압력개폐밸브(34)가 압축스프링(48)의 반발력에 의해 잠금이 풀려있게 되므로 유압잭(JACK)(6)의 작동봉(8)에 연결 형성된 연결편(16)과 고정판(14) 사이에 스프링(18)에 의해 유압잭(6)의 작동봉(8) 또한 최대 후퇴한 상태가 되어 절단날(10)과 지지편(12)의 칼날(14) 사이에 상시 적정 간격이 유지된 상태로 있게 된다. 그리고, 이 상태에서 철근(64)의 절단작업을 해주고자 할 경우에는 작업자가 한 손으로는 본체(2)의 파지부(62)를 잡고 다른 한 손으로는 지지부(50)의 상부로 부터 바로 아래에 설치된 작동손잡이(54)를 함께 움켜 쥔 다음 절단날(10)과 지지편(12)의 칼날(14) 사이에 절단해 주고자 하는 철근(64)이 위치토록 하여 다른 한 손으로 움켜 쥔 작동손잡이(54)를 스프링(48)의 반발력보다 더욱 강할 힘으로 움켜쥐게 되면 작동손잡이(54)가 축핀(52)에 연결된 연결끈(42)이 당겨지게 되므로 연결끈(42)의 당김작동에 의해 압력개폐밸브(34)가 반시계방향으로 회전하여 잠김이 이루어지게 된다.The present invention constituted as described above, the pressure opening and closing valve 34 is released by the repulsive force of the compression spring 48, so the connecting piece 16 and the fixed plate (16) formed connected to the operating rod 8 of the hydraulic jack (JACK) 6 The operating rod 8 of the hydraulic jack 6 is also retracted by the spring 18 between the cutting edges 10 and the proper interval is always maintained between the cutting blade 10 and the blade 14 of the support piece 12. It will remain In this state, in order to cut the reinforcing bar 64 in this state, the worker grasps the grip portion 62 of the main body 2 with one hand, and directly from the upper portion of the support 50 with the other hand. Grasp the operation knob 54 installed below and grip the other hand with the rebar 64 to be cut between the cutting blade 10 and the blade 14 of the support piece 12. When the operation handle 54 is gripped with a force stronger than the repulsive force of the spring 48, the operation handle 54 is pulled by the connecting strap 42 connected to the shaft pin 52, so that the operation of the connecting strap 42 is pulled. As a result, the pressure opening / closing valve 34 rotates in a counterclockwise direction, thereby locking.

또한 작동손잡이(54)의 작동으로 압력개폐밸브(34)의 잠김과 동시에 작동손잡이(54)의 단면이 지지부(50)의 내측으로 돌출 형성된 눌름스위치(58)의 작동봉(60)을 눌러 스위치(58)를 ON시켜 주게 되므로 전동기(20)가 구동하여 구동기어(24)와 치합된 피동기어(26)를 회전시켜 주게 되고 피동기어(26)의 편심축(28)과 연결된 작동간(32)이 좌우 연속 왕복 작동하여 유압잭(6)의 작동실린더(30)를 작동시켜 주게 되므로 작동봉(8)에 연결 고정된 절단날(10)이 전진 작동하여 지지편(12)의 고정날(14)과 절단날(10)사이의 간격이 점차 좁아져 그 사이에 위치한 철근(64)이 절단되는 것이다.In addition, by operating the operating knob 54, the pressure opening and closing valve 34 is closed, and at the same time, the end of the operating knob 54 presses the operating rod 60 of the push switch 58 formed to protrude into the support 50. Since the 58 is turned on, the electric motor 20 is driven to rotate the driven gear 26 engaged with the drive gear 24 and is connected to the eccentric shaft 28 of the driven gear 26. ) And the left and right continuous reciprocating operation to operate the operation cylinder 30 of the hydraulic jack (6), so that the cutting blade 10 connected to the operating rod (8) is moved forward to the fixed blade (14) of the support piece (12) ) And the gap between the cutting blade 10 is gradually narrowed and the reinforcing bar 64 located therebetween is cut.

철근(64)이 절단되었음을 확인한 작업자는 작동손잡이(54)를 잡고 있는 손을 느슨하게 놓아주게 되면 잠금 방향의 연결끈(42)을 당기고 있던 힘이 소멸되어 눌름스위치(58)의 전원이 OFF되어 전동기(20)의 전원이 차단되므로 유압잭(6)의 작동은 정지하게 되고, 또한 이와 동시에 잠금의 해지방향에 연결 설치된 압축스프링(48)의 반발력에 의해 압력개폐밸브(34)가 풀려지게 되므로 유압잭(6)의 압력은 배출되고 압력배출로 그 힘이 상실된 작동봉(8)은 연결편(16)과 고정판(4)사이에 연결 설치된 스프링(18)에 의해 원복되므로 절단날(10)과 고정칼(14) 사이에 간격이 벌어져 다음 작업을 대비하게 된다.When the worker who confirms that the reinforcing bar 64 has been cut releases the hand holding the operation handle 54 loosely, the power pulling the connecting string 42 in the locking direction is lost and the power of the push switch 58 is turned off to turn off the electric motor. Since the power of the 20 is cut off, the operation of the hydraulic jack 6 is stopped, and at the same time, the pressure opening and closing valve 34 is released by the repulsive force of the compression spring 48 installed in the direction of release of the lock. The pressure of 6) is discharged and the operating rod 8 whose pressure is lost by the pressure discharge is retracted by the spring 18 installed between the connecting piece 16 and the fixing plate 4, so that the cutting blade 10 and the fixed knife ( 14) There is a gap in between to prepare for the next task.

이상 설명한 바와 같이 본 고안은 전동기(20)에 의해 작동되는 유압잭(6)의 작동봉(8)에 절단날(10)을 형성하여 지지부(50)에 설치된 작동손잡이(54)를 통하여 유압잭(6)의 압력개폐밸브(34)를 잠금과 동시에 전동기(20)를 구동시켜 유압잭(6)의 일측에 연결 형성된 절단날(10)이 전진토록 하므로서 절단날(10)과 고정칼날(14) 사이에 위치한 철근(64)이 절단되고 절단작업후에는 다시 작동손잡이(54)를 통하여 전동기(20)를 정지시키고 압력개폐밸브(34)를 풀어 유압잭(6)의 압력이 배출되게 하면 절단날(10)이 스프링(18)에 의해 원복되어 다음 작업이 바로 진행될 수 있도록 하므로서 사용이 편리함은 물론 비교적 부피가 작고 가벼워 취급과 이동이 매우 용이하고, 또한 종래 산소와 LPG를 사용하므로서 부대비용이 많이 소요되고, 항상 화재나 폭발의 위험이 있던 것을 없애주도록 하는 등의 많은 효과가 있는 것이다.As described above, the present invention forms a cutting blade 10 on the operating rod 8 of the hydraulic jack 6 operated by the electric motor 20 and the hydraulic jack 6 through the operating handle 54 installed on the support 50. At the same time as locking the pressure opening and closing valve (34) of the electric motor 20 to drive the cutting blade 10 formed connected to one side of the hydraulic jack (6) between the cutting blade 10 and the fixed blade (14) When the reinforcing bar 64 is cut and the cutting operation is performed again, the motor 20 is stopped again through the operation knob 54, and the pressure opening and closing valve 34 is released to release the pressure of the hydraulic jack 6. It is easy to use as it is restored by the spring 18 so that the next work can be immediately performed, as well as relatively small and light, so it is very easy to handle and move, and also requires a lot of additional costs by using conventional oxygen and LPG, There was always a risk of fire or explosion Kids will have many effects such as to give.
