도 10은 본 발명에 따른 현수교 바 행어장치가 현수교에 설치된 상태를 도시한 예시도이다.10 is an exemplary view illustrating a suspension bridge bar hanger device according to the present invention installed in a suspension bridge.

이 도면에 도시된 바와 같이, 본 발명에 따른 현수교 바 행어장치를 이용한 현수교 변위제어방법은 전체적으로 삼각형상으로 이루어짐과 동시에 내측에 관통공(12)이 형성된 주케이블정착부(10)와; 상기 주케이블정착부(10)의 관통공(12)의 양측에 배치되는 내측 원형링(14)과; 상기 내측 원형링(14)의 외측에 배치되는 슬라이딩 원형판(16)과; 상기 주케이블정착부(10)로부터 일정한 간격이 이격된 상태로 대향되며, 전체적으로 삼각형상으로 이루어짐과 동시에 내측에 관통공(22)이 형성된 보강거더정착부(20)와; 상기 보강거더정착부(20)의 관통공(22)의 양측에 배치되는 내측 원형링(24)과; 상기 내측 원형링(24)의 외측에 배치되는 슬라이딩 원형판(26)과; 상기 주케이블정착부(10)의 슬라이딩 원형판(16)과 보강거더정착부(20)의 슬라이딩 원형판(26)의 외측에 각각 배치됨과 동시에 양단부에 관통공(32)이 형성된 타원형상의 행어판(30)과; 상기 행어판(30)의 관통공(32) 외측에 각각 배치되는 외측 원형링(40)과; 상기 외측 원형링(40)의 상부와 하부에 각각 관통 삽입되는 고정핀(50)으로 구성된 현수교 바 행어장치(A)를 주케이블(C)과 보강 거더(G)에 고정 설치하여 현수교(B)의 변위를 제어하는 것이다.As shown in this figure, the suspension bridge displacement control method using the suspension bridge bar hanger device according to the present invention is made of a triangular shape as a whole and the main cable fixing portion 10 formed with a through hole 12 therein; An inner circular ring 14 disposed at both sides of the through hole 12 of the main cable fixing part 10; A sliding circular plate (16) disposed outside the inner circular ring (14); A reinforcement girder fixing part 20 which is opposed to the main cable fixing part 10 at a predetermined distance from the main cable fixing part 10 and is formed in a triangular shape as a whole and has a through hole 22 formed therein; An inner circular ring 24 disposed at both sides of the through hole 22 of the reinforcement girder fixing part 20; A sliding circular plate (26) disposed outside the inner circular ring (24); The elliptical hanger plate 30, which is disposed outside the sliding circular plate 16 of the main cable fixing part 10 and the sliding circular plate 26 of the reinforcing girder fixing part 20, and has through-holes 32 formed at both ends thereof. )and; An outer circular ring 40 disposed outside the through hole 32 of the hanger plate 30; Suspension bridge bar hanger device (A) consisting of fixing pins 50 inserted through and respectively inserted into the upper and lower portions of the outer circular ring 40 is fixed to the main cable (C) and reinforcement girders (G) by suspension bridge (B). To control the displacement.

즉, 일반적으로 현수교의 행어케이블은 활하중 및 풍하중의 재하에 의한 보강거더의 변위에 따른 행어의 휨변형의 영향을 고려하도록 기준되어 있으며, 행어케이블이 2m 이상이고 변위차(상대변위)에 의한 꺾임각이 4도 이하로 제한하여 행어에 과도한 휨변형이 생기지 않도록 하는 행어정착구조를 하는 것을 기본으로 하고 있다.That is, in general, the hanger cables of suspension bridges are considered to take into account the influence of the bending deformation of the hanger according to the displacement of the reinforcement girder due to the load of live and wind loads.The hanger cable is 2m or more and is bent due to the displacement difference (relative displacement). It is based on the hanger fixing structure that the angle is limited to 4 degrees or less to prevent excessive bending deformation in the hanger.

교량설계기술이 발전함에 따라 현수교의 주경간장이 증가하고 있으며, 이에 따라 수평방향변위가 증가하여 중앙부 행어의 꺾임각이 크게 발생하여 과도한 휨변형이 발생할 가능성이 커 행어케이블 설계시 주의가 요구되고 있다.As bridge design technology develops, the main span length of suspension bridges is increasing. As a result, the horizontal displacement increases and the bending angle of the central hanger is greatly increased, causing excessive bending deformation. .

따라서, 상기한 바와 같은 현수교 바 행어장치(A)를 주케이블(C)과 보강거더(G) 간에 사용하였을 경우에는 일반 행어 케이블보다 상대변위를 75% 정도 줄일 수 있으므로 중앙행어의 꺾임각을 최소화하여 부가장치의 사용 없이 휨변형을 줄일 수 있으며, 일종의 강봉 형태의 행어장치로서 유지관리가 용이하여 현수교의 장대화에 기여하는 작용효과가 있다.Therefore, when the suspension bridge bar hanger device (A) as described above is used between the main cable (C) and the reinforcement girder (G), the relative displacement can be reduced by 75% compared to the general hanger cable, thereby minimizing the bending angle of the central hanger. Therefore, it is possible to reduce the bending deformation without using the additional device, and it is a kind of hanger device of the steel bar type, which is easy to maintain and has the effect of contributing to the extension of the suspension bridge.
