Reinforcement method and reinforcement structure of seismic detailing hoop using fixed device
The present invention relates to arrangement of tie hoops applying seismic details of a rebar concrete column, comprising a main rebar (1a) longitudinally installed to form a rectangular rebar concrete column member and a tie hoop (1b) to surround the periphery of the main rebar at a right angle. An objective of arrangement of tie hoops in accordance with existing seismic details is to bend (hook) an end part of the tie hoop by 135 degrees to prevent the tie hoop from being opened, such that restriction effect is provided to ensure flexibility and seismic performance of the rebar concrete column in occurrence of a seismic load by buckling prevention of the main rebar (1a). According to the present invention, as an alternative to remarkably improve a disadvantage that a method to bend (hook) an existing tie hoop by 135 degrees is difficult to couple a rebar in construction of the tie hoop so as to lower work efficiency and require a lot of time, the end of the tie hoop (2b) is bent (hooked) by 90 degrees and opening of the tie hoop (2b) is prevented by a fixing device (2c) to realize a complete restriction effect so as to make work become efficient while satisfying application of seismic details, thereby rebar arrangement constructability of a rebar concrete column is largely improved.
본 발명은 철근콘크리트 기둥의 내진상세가 적용된 띠철근 배근에 관한 것으로, 사각 형태의 철근콘크리트 기둥 부재 형성을 위해 길이방향으로 설치된 주철근(1a); 상기 주철근 둘레를 직각방향으로 감싸는 띠철근(1b)으로 종래 내진상세에 따른 띠철근의 배근은 띠철근의 끝단을 135˚로 절곡(훅크)(1d)하여 띠철근이 벌어지는 걸 방지함으로서 구속효과가 있어 지진하중 발생시 주철근(1a)의 좌굴 방지로 철근콘크리트 기둥의 연성 및 내진성능을 확보 하는 목적이 있다. 본 발명에 따르면, 기존 띠철근 135˚로 절곡(훅크)(1d) 방식은 띠철근 시공시 철근 체결의 어려움이 많아 작업효율의 저하 및 많은 시간이 소요되는 단점을 획기적으로 개선한 대안으로 띠철근(2b)의 끝단을 90˚로 절곡(훅크) 설치 후 고정장치(2c)를 이용하여 띠철근의 벌어짐을 방지하여 완벽한 구속효과로 내진상세 적용을 만족시키면서 작업의 효율화로 철근콘크리트 기둥의 배근 시공성을 크게 향상시키는 것이다.
