본 발명은 공동주택 배전용 케이블 트레이에 관한 것으로, 더욱 상세하게는 케이블 트레이에 의해 포설되는 전력케이블을 고정하기 위한 결속밴드시공을 보다 편리하게 할 수 있도록 한 공동주택 배전용 케이블 트레이에 관한 것이다.The present invention relates to a cable tray for multi-family home distribution, and more particularly, to a cable tray for multi-family home distribution which makes it easier to construct a binding band for fixing a power cable laid by the cable tray.

일반적으로 공장주택에는 각 세대의 전원공급을 위해 크고 작은 직경의 전력케이블이 천장 및 바닥 또는 벽체를 따라 시공되는데 특히 천장을 따라 시공되는 전력케이블은 케이블 트레이를 이용해서 정돈된 상태로 시공되어 케이블 설치 및 복수, 점검을 용이하게 하고 있다.In general, factory houses have large and small diameter power cables installed along the ceiling, floor, or wall to supply power for each household. In particular, power cables installed along the ceiling are neatly constructed using cable trays. And plural inspections are facilitated.

이와 같은 종래 공동주택 배전용 케이블 트레이를 첨부도면 도1 및 도2에 도시하였는 바, 이에 도시된 바와 같이 천장에 설치된 행거볼트(11)(12)의 하단부에 너트(13a)(13b)를 이용해서 지지바(14)를 설치하고, 렁(15)에 의해 연결된 사이드레일(16)(17)을 지지바(14) 위에 올린 상태로 고정하도록 되어 있었다.As shown in the accompanying drawings, Figures 1 and 2 of the conventional multi-unit housing distribution cable tray, as shown therein using a nut (13a) (13b) on the lower end of the hanger bolt (11) 12 installed on the ceiling The support bar 14 was installed and the side rails 16 and 17 connected by the rung 15 were fixed on the support bar 14.

또, 시공된 케이블 트레이(10)에 전력케이블(18)을 일정한 간격으로 포설한 다음 전력케이블(18)이 움직이지 못하도록 결속밴드(19)를 이용해서 렁(15)에 고정하였다.In addition, the power cable 18 was installed at regular intervals in the constructed cable tray 10 and then fixed to the rung 15 using the binding band 19 to prevent the power cable 18 from moving.

그러나, 종래 케이블 트레이(10)에 구비된 렁(15)은 전력케이블(18)과 직교하기 때문에 결속밴드(19)를 렁(15)에 고정할 때 전력케이블(18)과 렁(15)이 교차하는 지점에서 대각선방향으로 고정할 수밖에 없어 전력케이블(18)이 일직선을 이루지 못하고 결속밴드(19)에 의해 한쪽방향으로 밀리면서 휘는 문제점이 있었다.However, since the rung 15 provided in the cable tray 10 is orthogonal to the power cable 18, the power cable 18 and the rung 15 are fixed when the binding band 19 is fixed to the rung 15. There is a problem in that the power cable 18 does not form a straight line at the intersection point, but is bent while being pushed in one direction by the binding band 19.

또한, 종래에는 결속밴드(19)가 사선방향으로 고정되기 때문에 결속밴드(19)에 의한 결속력이 전력케이블(18)의 국부에 집중되면서 전력케이블(18)의 절연피복이 쉽게 손상되는 문제점이 있었다.In addition, in the related art, since the binding band 19 is fixed in an oblique direction, there is a problem in that the insulation coating of the power cable 18 is easily damaged while the binding force by the binding band 19 is concentrated on the local portion of the power cable 18. .

Since the binding force by the binding band 40 is evenly distributed without being concentrated in the insulation coating portion of the power cable 20, the insulation coating of the power cable 20 can be prevented from being damaged as well as the power cable. It is possible to prevent the 20 from being bent or deformed.

또, 묶음턱(31)(32)의 모서리부분에 형성된 이탈방지턱(31a)(32a)은 결속밴드(40)가 전력케이블(20)의 길이방향을 따라 묶음턱(31)(32)으로부터 미끄러져 이탈되는 것을 방지하는 작용을 하게 된다.In addition, the separation prevention barriers 31a and 32a formed at the corners of the bundle jaws 31 and 32 have a binding band 40 that slides from the bundle jaws 31 and 32 along the longitudinal direction of the power cable 20. It is to prevent the falling off.

그리고, 묶음턱(31)(32)이 렁(30)의 양측 가장자리를 따라 계단형으로 형성되어 있기 때문에 전력케이블(20)을 포설할 때 이 묶음턱(31)(32)의 간격과 동일한 배수간격을 유지하게 되면, 전력케이블(20)의 간격을 일정하게 조절할 수 있게 된다.In addition, since the bundle jaws 31 and 32 are formed stepwise along both edges of the rung 30, the same multiple as the spacing of the bundle jaws 31 and 32 when the power cable 20 is laid. If the interval is maintained, it is possible to constantly adjust the interval of the power cable (20).
