It is formed in the site and is formed by a combination of fasteners 30 that can achieve a fixed connection of the transmission and distribution wires 2 located in the tile side direction.

여기서 상기 활형 판 스프링(10)은 활형 형상을 이루고 있되, 외측 중앙부위에는 마감 너트캡(32)을 이용한 송배전 전선(2)의 잠금 설치를 이룰 수 있는 절개홈(34)이 중앙에 일체로 형성되어 있는 고정구(30)가 일체로 돌출 형성되어 있고, 양측에는 수직으로 관통된 연결공(12)이 일체로 형성되어 있다.Here, the bow leaf spring 10 has a bow shape, but an outer center portion is integrally formed with an incision groove 34 formed at the center thereof to lock the transmission and distribution wire 2 using the closing nut cap 32. The fixture 30 which is present is integrally formed, and the connecting hole 12 vertically penetrated is formed integrally at both sides.

그리고, 상기 반호형 절첩 연결구(20)는 절첩 개폐가 가능한 2조 한쌍의 부재로 이루어져 있되, 외주연 중앙 부위에는 전방으로 연장 돌출되어 있는 연결구(22)가 형성되어 있으며, 상기 연결구(22)의 전방에는 수직 관통된 구멍(24)이 각각 형성되어 있어, 상기 활형 판 스프링(10)의 양측에 형성되어 있는 연결공(12)에 고정볼트(4)를 이용한 연결 고정이 가능한 형상을 이루고 있다.In addition, the half arc-type folding connector 20 is composed of a pair of two members that can be opened and closed, the outer peripheral center portion is formed with a connector 22 which protrudes forward, the connector 22 of the Vertically through holes 24 are formed in the front, and the connection holes 12 formed on both sides of the bow-shaped leaf spring 10 form a shape capable of connection fixing using the fixing bolts 4.

이와 같이 구성되어 있는 본 발명의 설치 방법과 이에 따른 작용 효과를 도면을 참조하여 설명하면 다음과 같다.Referring to the installation method and the effect according to the present invention configured as described above with reference to the drawings as follows.

도 4a는 본 발명인 송배전 전선의 처짐 방지 시설물의 초기 상태를 도시한 평면도이고, 도 4b는 본 발명인 송배전 전선의 처짐 방지 시설물의 작동 상태를 도시한 평면도이다.Figure 4a is a plan view showing the initial state of the sag prevention facility of the present invention transmission and distribution wires, Figure 4b is a plan view showing the operating state of the sag prevention facility of the present invention transmission and distribution wires.

본 발명은 전주(1)에 송배전 전선(2)을 긴밀한 장력을 주어 가선하기 전에 송배전 전선(2) 길이 방향에 걸쳐 의도한 갯수(횡방향으로 당겨지게 하여 수직방향 늘어짐을 방지할 수 있도록 하는..) 만큼 연결 설치를 이루어 사용하는 것으로, 세부적인 설치 과정을 설명하면 다음과 같다.The present invention is to give the electric pole (1) a tight tension of the transmission and distribution wires (2) before the line is wired to the intended number over the length of the transmission and distribution wires (2) to be pulled in the transverse direction to prevent the vertical sag. The connection installation is as much as.) And the detailed installation process is as follows.

즉, 전주(1)의 경완금(3) 양측에 적어도 2조 한쌍으로 가선되는 송배전 전선(2) 중 일측에 위치한 송배전 전선(2)에 일정 간격을 두고 2개의 반호형 절첩 연결구(20)를 위치 시킨다.That is, the two half arc-type folding connectors 20 are spaced at a predetermined distance from the transmission and distribution wires 2 located on one side of the transmission and distribution wires 2 wired to at least two pairs on both sides of the light arm 3 of the pole 1. Position it.

이때 상기 송배전 전선(1)에 위치되는 반호형 절첩 연결구(20)의 연결은 연결구(24)가 위치한 전방을 개구시켜 내측에 송배전 전선(2)을 위치되게 하면 된다.In this case, the connection of the half arc-type folded connector 20 located in the transmission and distribution wire 1 may open the front where the connector 24 is located so that the transmission and distribution wire 2 is positioned inside.

그리고, 이러한 상태를 취함과 동시에 상기 반호형 절첩 연결구(20)의 전방 상,하 부위에 형성되어 있는 연결구(22) 자체에 형성되어 있는 구멍(24) 사이에 활형 판 스프링(10)의 연결공(12)을 위치시킨 후 고정볼트(4)와 너트(5)를 이용하여 연결 시키면 된다.In addition, the connection hole of the spring plate 10 between the holes 24 formed in the connector 22 itself formed in the front upper and lower portions of the half arc-shaped folding connector 20 while taking this state. After positioning (12), it is possible to connect using the fixing bolt (4) and the nut (5).

이와 같이 조립 연결된 활형 판 스프링(10)의 외측 중앙 부위에 일체로 돌출 형성되어 있는 고정구(30)의 절개홈(34)에 타측에 위치한 송배전 전선(2)을 위치시킨 후 마감 너트캡(32)을 이용하여 잠금 설치를 이루면 설치가 완료되게 된다.Thus, the closing nut cap 32 after positioning the transmission and distribution wires 2 located on the other side in the cutout groove 34 of the fixture 30 is formed integrally protruding to the outer center portion of the bow-shaped leaf spring (10) connected to the assembly If you make a lock installation using the installation is completed.

이러한 조립 설치 과정을 통해 상술한 바와 같이 의도한 갯수 만큼의 처짐 방지 시설물의 설치가 이루어진 송배전 전선(2)을 송배전 전선 가선용 풀러(미도시하였음)와 같은 장치를 이용하여 전주(1) 사이에 긴밀한 장력을 주어 연결 설치하면 의도한 작용을 도모할 수 있는 설치 과정이 모두 완료되게 된다. Through this assembly installation process, as described above, the transmission and distribution wires 2 in which the intended number of deflection prevention facilities are installed are installed between the poles 1 using a device such as a puller (not shown) for transmission and distribution wires. If you install tightly connected with tension, the installation process is completed to achieve the intended action.

즉, 송배전 전선(2)간의 팽팽한 상태를 이루게 되는 장력 변화에 의해 초기 형상이 반원형의 활형을 이루고 있던 활형 판 스프링(10)이 도 4a 도시된 바와 같이 펴진 상태로 송배전 전선(2) 사이에 설치되게 된다.That is, the bow leaf spring 10 whose initial shape is a semicircular bow shape is installed between the power distribution wires 2 in an unfolded state as shown in FIG. 4A by the change in tension between the power distribution wires 2. Will be.

그러므로 송배전 전선(2)을 늘어지게 하는 장력 변화시에는 상기 활형 판스프링(10)의 초기 형상을 유지고자 하는 탄성 복원력에 의해 대응 반응하여 도 4b에 도시된 바와 같이 송배전 전선(2)이 횡방향으로 벌어지게 되므로 수직 방향 처짐 현상을 최소화할 수 있게 된다. Therefore, in the case of a tension change that causes the transmission and distribution wires 2 to be stretched, the transmission and distribution wires 2 are transversely oriented as shown in FIG. 4B in response to the elastic restoring force to maintain the initial shape of the bow leaf spring 10. Since it is to be spread out as the vertical sag phenomenon can be minimized.
