본 발명은 전력용 케이블 트레이 고정구에 관한 것으로, 더욱 상세하게는 걸림핀과 편심체에 의해 케이블트레이의 좌우측에 위치하는 C형강을 행거 하단에 설치된 트레이받침파이프에 고정하는데 이용하는 전력용 케이블 트레이 고정구에 관한 것이다.The present invention relates to a cable tray fastener for power, and more particularly, to a cable tray fastener for power used to fix the C-shaped steel located on the left and right sides of the cable tray by a locking pin and an eccentric body to a tray support pipe installed at the bottom of the hanger. It is about.

일반적으로 아파트단지 등의 공동주택에는 전력선과 통신선 등의 많은 케이블이 설치되는데, 이러한 케이블은 통상 건물의 지하층 등에 배선된다. 이 경우 케이블을 공중으로 배선할 경우 자체의 하중으로 인해 아래로 처질 뿐 아니라 다른 구조물과 간섭되어 손상될 우려가 높다.In general, a lot of cables such as power lines and communication lines are installed in apartment houses such as apartment complexes, which are usually wired to the basement floor of a building. In this case, if the cable is routed in the air, it is not only sag down due to its own load, but also there is a high risk of interference with other structures.

따라서, 상기의 케이블을 수용하는 케이블트레이를 슬래브 아래로 설치된 행거에 안착시켜 케이블을 지지하는 구조가 이용되고 있으며, 그 일예로 국내 실용신안등록 출원번호 제20-2002-0030143호(명칭; 케이블 트레이 고정구)는 첨부도면 도1에 도시된 바와 같이 역(逆) "V"자 모양으로 절곡된 고정구(11)의 단부에 톱니(12)를 형성하고, 고정구(11) 중앙과 트레이받침파이프(13)를 관통하는 볼트(14) 에 의해 C형강(15)의 하부절곡부(16)를 압박함으로써 케이블트레이(10)와 트레이받침파이프(13)를 체결하도록 되어 있었다.Therefore, a structure for supporting the cable by mounting the cable tray for accommodating the cable to a hanger provided under the slab is used.

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도2 내지 도6에 도시된 바와 같이 클램프(50)에 가압볼트(56) 및 걸림핀(70)을 조립하는 과정은 이후 클램프(50)에 형성되어 있는 나사구멍(54)에 가압볼트(56)를 결합한 다음 클램프(50)의 저면에 형성되어 있는 회전방지편(58)의 핀구멍(59)에 걸림핀(70)을 압입하게 되면, 회전핀(80)과 가압볼트(56) 및 걸림핀(70)이 클램프(50)에 조립된다.2 to 6, the process of assembling the pressure bolt 56 and the locking pin 70 to the clamp 50 is then performed by the pressure bolt to the screw hole 54 formed in the clamp 50. When the engaging pin 70 is pressed into the pin hole 59 of the anti-rotation piece 58 formed on the bottom surface of the clamp 50 after engaging the 56, the rotating pin 80 and the pressing bolt 56 are pressed. And the locking pin 70 is assembled to the clamp 50.

한편, 트레이받침파이프(40) 위에 C형강(60)을 얹은 다음 클램프(50)의 저면에 형성되어 있는 회전방지편(58)과 걸림핀(70)을 트레이받침파이프(40)의 상면(42)에 형성되어 있는 십자구멍(30)에 일치시킨 상태에서 십자구멍(30)의 가로홈(32)과 세로홈(34)에 회전방지편(58)과 걸림핀(70)을 삽입한 후 클램프(50)를 후퇴시키게 되면, 걸림핀(70)이 트레이받침파이프(40)의 내측면(44)에 걸리게 되고, 회전방지편(58)은 십자구멍(30)의 가로홈(32)에 결합된다.Meanwhile, the C-shaped steel 60 is placed on the tray support pipe 40, and then the upper surface 42 of the tray support pipe 40 has the anti-rotation piece 58 and the locking pin 70 formed on the bottom surface of the clamp 50. The rotation prevention piece 58 and the locking pin 70 into the horizontal groove 32 and the vertical groove 34 of the cross hole 30 in a state where the cross hole 30 is formed in the When the 50 is retracted, the engaging pin 70 is caught by the inner surface 44 of the tray support pipe 40, the anti-rotation piece 58 is coupled to the horizontal groove 32 of the cross hole (30) do.

이후 클램프(50)를 상측으로 당기게 되면, 회전방지편(58)에 설치되어 있는 걸림핀(70)이 트레이받침파이프(40)의 내측면(44)에 걸리면서 클램프(50)의 저면과 트레이받침파이프(40)의 상면 사이에 공간이 형성되는데, 이 공간으로 편심체(90)를 옆으로 밀어서 집어넣은 다음 편심체(90)에 형성된 나사홀(95)과 클램프(50)에 형성되어 있는 수직구멍(82)의 중심을 일치시킨 상태에서 수직구멍(82)으로 회전핀(80)을 삽입하여 회전핀(80) 상단에 형성된 육각홈(84)에 육각렌치를 결합한 다음 회전핀(80)을 돌리게 되면, 회전핀(80) 하단에 형성된 수나사부(81)가 나사홀(95)에 결합된다.Then, when the clamp 50 is pulled upward, the locking pin 70 installed on the anti-rotation piece 58 is caught by the inner surface 44 of the tray support pipe 40 and the tray bottom of the clamp 50 is supported. A space is formed between the upper surface of the pipe 40, and the space is pushed into the eccentric body 90 to the side, and then the vertical hole formed in the clamp hole 50 and the screw hole 95 formed in the eccentric body 90 Insert the rotary pin 80 into the vertical hole 82 in the state where the center of the hole 82 coincides with the hexagonal wrench 84 formed on the upper end of the rotary pin 80, and then rotate the rotary pin 80. When turned, the male screw portion 81 formed at the bottom of the rotary pin 80 is coupled to the screw hole (95).

이때 수직구멍(82)의 상단과 회전핀(80)의 외주면에 형성되어 있는 멈춤홈(86)의 높이가 일치되는데, 이 멈춤홈(86)으로 스냅링(88)을 측방향으로 밀어서 결합하게 되면, 회전핀(80)이 클램프(50)로부터 이탈되지 않고 회전만 가능하게 된다.At this time, the height of the stop groove 86 formed on the upper end of the vertical hole 82 and the outer circumferential surface of the rotary pin 80 coincides. When the snap ring 88 is coupled to the stop groove 86 by pushing in the lateral direction, The rotation pin 80 is only rotated without being separated from the clamp 50.

위와 같은 상태에서 회전핀(80)의 상단에 형성된 육각홈(84)에 육각렌치를 다시 결합한 상태에서 회전핀(80) 하단에 형성된 수나사부(81)와 편심체(90)에 형 성된 나사홀(95)이 결합되는 방향으로 회전핀(80)을 돌리게 되면, 회전핀(80)과 편심체(90)는 이미 결합되어 있기 때문에 회전핀(80)과 편심체(90)가 동시에 회전되며, 편심체(90)가 C형강(60)의 하부절곡부(62)에 점점 가까워지면서 밀착되어 압력을 가하게 된다.The screw hole formed in the male screw portion 81 and the eccentric body 90 formed at the lower end of the rotating pin 80 in a state in which the hexagonal wrench 84 is formed at the top of the rotating pin 80 again in the above state. When the rotating pin 80 is rotated in the direction in which the 95 is coupled, since the rotating pin 80 and the eccentric body 90 are already coupled, the rotating pin 80 and the eccentric body 90 are rotated at the same time. The eccentric body 90 is in close contact with the lower bent portion 62 of the C-shaped steel 60 is pressed to apply pressure.

이때 클램프(50)의 회전방지편(58)이 십자구멍(30)의 가로홈(32)에 걸려 있기 때문에 클램프(50)는 더 이상 후퇴하지 않게 되어 C형강(60)은 편심체(90)에 의해 강한 힘을 받아 고정되며, 회전핀(80)과 편심체(90)의 풀림을 발생하지 않게 된다.At this time, since the rotation preventing piece 58 of the clamp 50 is caught in the horizontal groove 32 of the cross hole 30, the clamp 50 is no longer retracted, and the C-shaped steel 60 is the eccentric body 90. It is fixed by receiving a strong force, and the rotation pin 80 and the eccentric body 90 does not occur loosening.

그 다음 클램프(50)에 결합되어 있는 가압볼트(56)를 조이게 되면, 가압볼트(56)가 C형강(60)의 하부절곡부(62)를 트레이받침파이프(40)의 상면(42)을 압박하는 동시에 반력에 의해 클램프(50)의 후단에 위치된 원호형지지부(52)를 지점으로 해서 가압볼트(56)가 설치된 부분인 클램프(50)의 선단이 상측으로 들뜨게 되는데, 이때 클램프(50)의 회전방지편(58)에 설치된 걸림핀(70)이 트레이받침파이프(40)의 내측면(44)에 걸려 있기 때문에 클램프(50)는 더 이상 들뜨지 못하고 정지하여 C형강(60)을 압박하게 된다.Then, when tightening the pressure bolt 56 is coupled to the clamp 50, the pressure bolt 56 is the lower bent portion 62 of the C-shaped steel 60 to the upper surface 42 of the tray support pipe 40 At the same time, the tip of the clamp 50, which is the portion in which the pressure bolt 56 is installed, is lifted upward by the circular arc supporting portion 52 positioned at the rear end of the clamp 50 by the reaction force. Since the engaging pin 70 installed on the anti-rotation piece 58 of the) is caught on the inner surface 44 of the tray support pipe 40, the clamp 50 stops lifting and presses the C-shaped steel 60.

즉, C형강(60)이 편심체(90)에 의해 측방향으로 힘을 받는 경우 좌우 양측에 위치된 C형강(60)이 중간에 설치된 크로스바(100)에 의해 벌어지지 않기 때문에 바깥쪽으로 힘을 받아 고정된 상태를 유지하게 된다.That is, when the C-shaped steel 60 receives the force in the lateral direction by the eccentric body 90, because the C-shaped steel 60 located on both left and right sides is not opened by the crossbar 100 installed in the middle, Receive and remain fixed.

이상에서 설명한 바와 같은 본 발명은 트레이받침파이프의 상면에 형성되어 있는 십자구멍의 가로홈에 결합되어 있는 회전방지편에 의해 클램프의 회전이 방지되도록 구성되어 있기 때문에 C형강이 온도변화에 의해 길이방향으로 크게 수축하거나 팽창하는 경우 클램프의 회전을 막아 풀림을 방지할 수 있는 효과가 있으며, 클램프를 트레이받침파이프에 형성된 십자구멍에 결합한 다음 가압볼트를 조이면 고정이 가능하기 때문에 조립작업이 케이블 트레이의 상측에서 모두 이루어지기 때문에 조립작업이 매우 편리하고 신속하게 되는 효과가 있다.As described above, the present invention is configured to prevent the rotation of the clamp by the rotation preventing piece coupled to the horizontal groove of the cross hole formed on the upper surface of the tray support pipe. When it is greatly contracted or expanded, it prevents the clamp from rotating and prevents loosening.It is possible to fix it by joining the clamp to the cross hole formed in the tray support pipe and then tightening the pressure bolt. Because it is all made in the assembly work is very convenient and has the effect of being quick.

더 나아가서 본 발명은 편심체에 의해 C형강을 측방향으로 밀어서 고정하도록 구성되어 있기 때문에 케이블 트레이의 측방향 유동을 막아 고정이 보다 견고하게 되는 효과도 있다.Furthermore, since the present invention is configured to push the C-shaped steel laterally by the eccentric body, it also has the effect of preventing the lateral flow of the cable tray to be more firmly fixed.
