The present invention relates to an easy-to-install cable-stayed bridge and a construction method thereof. The easy-to-install cable-stayed bridge comprises: an upper settling part (100) in which a plurality of cables (30) are continuously coupled to an upper portion of a tower (30) and settled thereon, and each of steel strands (31) of the cables (30) is elastically installed with an adjustment spring (144) while an exposed portion of the steel strand (31) is encapsulated with a protective agent (151) to be enclosed; a safety support part (200) installed on a bridge deck (20) at a proper height to seat and support a lower portion of each of the cables (30); and a lower settling part (130) for diagonally tensioning the cable (30) and settling the same on the bridge deck (20). Therefore, the easy-to-install cable-stayed bridge allows a tensile force of the cable to be uniformly applied, thereby settling the cable and absorbing vibrations, and allows the plurality of cables to be safely installed on the tower, thereby efficiently protecting the steel strands from which the sheath has been stripped and being easy to install.
본 발명은 설치가 용이한 사장교 및 그 시공방법에 관한 것으로, 주탑(30)의 상부에 여러가닥의 케이블(30)을 연속적으로 결합하여 정착시키되 케이블(30)의 강연선(31) 각각을 조절스프링(144)으로 탄력설치함과 동시에 강연선(31)의 노출부분에 보호제(151)를 충진하여 밀폐시키는 상부정착부(100)와, 상기 교량상판(20)에 적정 높이로 설치하여 케이블(30) 하부를 안치하여 지지하는 안전지지부(200), 및 상기 교량상판(20)에 케이블(30)를 경사지게 인장하여 정착시키는 하부정착부(130)로 구성하므로, 케이블의 인장력을 균일하게 인가하여 케이블을 정착할 수 있도록 함과 동시에 진동을 흡수할 수 있도록 하고 주탑에 복수개의 케이블을 안전하게 설치할 수 있도록 하며 피복이 벗겨진 강연선을 효율적으로 보호할 수 있도록 할 뿐만 아니라 설치가 용이한 것입니다.
