상기 U자형 받침고리(20)는 상기 배전케이블(50)이 안착되는 반원형 안착부(22)와, 상기 반원형 안착부(22)의 양끝단에서 상측방향으로 연장되어 형성된 수직부(24)로 구성된다.The U-shaped support ring 20 includes a semicircular seating portion 22 on which the distribution cable 50 is seated, and a vertical portion 24 extending upwardly from both ends of the semicircular seating portion 22. do.

상기 반원형 안착부(22)는 내주면 곡률반경이 배전케이블(50)의 외주면 곡률반경과 동일한 곡률반경으로 형성되는 것이 바람직하고, 상기 수직부(24)는 상하방향으로 복수개의 관통홀(24a)이 상하방향으로 소정간격을 이루며 형성된다.The semi-circular seating portion 22 is preferably formed with a radius of curvature of the inner circumferential surface curvature radius of the outer circumferential surface curvature of the distribution cable 50, the vertical portion 24 is a plurality of through holes 24a in the vertical direction It is formed to form a predetermined interval in the vertical direction.

상기 고정구(30)는 상기 U자형 받침고리(20)의 수직부(24)에 형성된 관통홀(24a)에 끼움되어 U자형 받침고리(20)와의 사이에 끼움공간(70)을 형성하는 것으로써, 상기 U자형 받침고리(20)의 관통홀(24a)에 끼움되고 외주면 양단에 나선부(32a)가 형성된 앙카봉(32)과, 상기 앙카봉(32)이 삽입되는 앙카나사(34)로 구성된다.The fastener 30 is fitted into the through hole 24a formed in the vertical portion 24 of the U-shaped support ring 20 to form a fitting space 70 between the U-shaped support ring 20. An anchor rod 32 is inserted into the through hole 24a of the U-shaped support ring 20 and has spiral portions 32a formed at both ends of the outer circumferential surface thereof, and the anchor screw 34 into which the anchor rod 32 is inserted. It is composed.

상기 앙카나사(34)는 상기 앙카봉(32)의 나선부(32a)에 맞물려 회전될 수 있도록 내주면에 나선부(34-1a)가 형성된 본체부(34-1)와, 상기 본체부(34-1)의 외주면 하단에서 하측방향을 향하여 연장되어 형성된 두 개의 돌기부(34-2)로 구성된다.The anchor screw 34 is a main body portion 34-1 having a spiral portion 34-1a formed on an inner circumferential surface thereof so as to be engaged with the spiral portion 32a of the anchor rod 32 and the main body portion 34. It consists of two projections 34-2 formed extending from the lower end of the outer peripheral surface of -1) toward the lower direction.

상기 앙카나사(34)의 두 개의 돌기부(34-2)는 그 사이 간격이 상기 철근망(10)의 수평철근(12) 두께와 동일하거나 그 보다 약간 크게 형성되어, 두 개의 돌기부(34-2) 사이에 수평철근(12)이 약간의 외력으로 억지끼움될 수 있도록 구성하는 것이 바람직하다. 따라서, 상기 앙카봉(32)이 상기 U자형 받침고리(20)의 관통홀(24a)을 관통하여 U자형 받침고리(20)의 수직부(24) 외측으로 앙카봉(32)의 나선부(32a)가 돌출되고, 상기 앙카봉(32)의 나선부(32a)에 앙카나사(34)가 나선결합되며, 상기 앙카나사(34)의 돌기부(34-2)에 의하여 고정구(30)가 U자형 받침고리(20)를 그네와 같은 놀이기구처럼 매단 채 상기 철근망(10)의 수평철근(12)에 안착되는 구성을 갖게 된다.The two projections 34-2 of the anchor screw 34 are formed to have a spacing therebetween equal to or slightly larger than the thickness of the horizontal reinforcement 12 of the reinforcing bar 10, and thus two projections 34-2. It is preferable to configure so that the horizontal reinforcing bars 12 can be pressed by a slight external force. Accordingly, the spiral rod 32 of the anchor rod 32 extends through the through hole 24a of the U-shaped support ring 20 to the outside of the vertical portion 24 of the U-shaped support ring 20. 32a protrudes, the anchor screw 34 is helically coupled to the spiral portion 32a of the anchor rod 32, and the fixture 30 is formed by the protrusion 34-2 of the anchor screw 34. It has a configuration that is seated on the horizontal reinforcement 12 of the reinforcing bar 10 while hanging the shaped support ring 20 like a playground equipment.

상기 배전케이블관(40)은 그 정단면 형상이 원형으로 구성되는 긴 관형태로써, 상기 배전케이블(50)이 복수개가 삽입되더라도 모두 수납할 수 있도록 충분히 그 내부공간을 확보한다.The distribution cable tube 40 is a long tube shape having a forward cross-sectional shape of a circular shape, even if a plurality of the distribution cables 50 are inserted to secure enough internal space to accommodate all of them.

상기와 같이 구성된 본 발명에 따른 배전케이블 설치구조의 설치과정을 살펴보면 다음과 같다.Looking at the installation process of the distribution cable installation structure according to the present invention configured as described above are as follows.

먼저, 콘크리트 구조물(60)을 만들기 위하여 그 골격으로 사용되는 철근망(10)을 만들어야 하는데, 상기 철근망(10)은 복수개의 수평철근(12)과 수직철근(14)을 서로 엮어서 메쉬(mesh) 형태로 만든 것이다. 이렇게 철근망(10)이 만들어지면 상기 철근망(10)을 좌우측에 배치한다.First, in order to make the concrete structure 60, the reinforcing bar 10 to be used as its skeleton should be made, the reinforcing bar 10 meshes a plurality of horizontal reinforcing bars 12 and vertical reinforcing bars 14 to each other. ) Is made in the form of. When the reinforcing bar 10 is made, the reinforcing bar 10 is disposed on the left and right sides.

그런 다음, 앙카봉(32)을 상기 U자형 받침고리(20)에 형성된 관통홀(24a)에 끼우고, 앙카나사(34)를 앙카봉(32)의 양단에 회전시켜 결합한다. Then, the anchor rod 32 is inserted into the through hole 24a formed in the U-shaped support ring 20, and the anchor screw 34 is rotated at both ends of the anchor rod 32 to be coupled.

이후, 앙카나사(34)의 돌기부(34-2)를 좌우측에 배치된 철근망(10)의 수평철근(12)에 끼운다.Thereafter, the projection 34-2 of the anchor screw 34 is inserted into the horizontal reinforcement 12 of the rebar network 10 arranged on the left and right sides.

이렇게 해서 U자형 받침고리(20)가 앙카봉(32)과 앙카나사(34)에 의하여 철근망(10)에 고정됐으면, 배전케이블(50)이 삽입된 배전케이블관(40)을 U자형 받침고리(20)와 앙카봉(32) 사이에 형성된 끼움공간(70)에 끼워넣는다.Thus, if the U-shaped support ring 20 is fixed to the reinforcing bar 10 by the anchor rod 32 and the anchor screw 34, the distribution cable tube 40 into which the distribution cable 50 is inserted is the U-shaped support. It is inserted into the fitting space 70 formed between the ring 20 and the anchor rod (32).

상기와 같이 구성되는 본 발명의 배전케이블 설치구조는 배전케이블이 삽입 된 배전케이블관을 철근망에 안정적으로 고정시킬 수 있으므로, 이후에 콘크리트가 타설되어도 배전케이블관의 위치가 변동되지 않아서 배전케이블이 비틀리거나 파손되는 것을 방지할 수 있는 이점이 있다.Since the distribution cable installation structure of the present invention configured as described above can stably fix the distribution cable tube into which the distribution cable is inserted, the reinforcing bar network, the distribution cable tube does not change even after the concrete is laid thereafter. There is an advantage that can be prevented from twisting or breaking.

또한, U자형 받침고리의 수직부에 관통홀이 상하방향으로 복수개가 천공되어 있어서, 배전케이블관의 직경에 따라서 앙카봉을 끼우는 위치를 조절할 수 있고 이에 따라 배전케이블관을 U자형 받침고리에 견고하게 밀착시킬 수 있는 이점이 있다.In addition, since a plurality of through holes are drilled in the vertical portion of the U-shaped support ring in the vertical direction, the position of the anchor rod can be adjusted according to the diameter of the distribution cable pipe, and thus the distribution cable pipe is firmly fixed to the U-shaped support ring. There is an advantage that can be closely adhered to.
