Abstract

에코 데크 플레이트 시스템은 철선일체형 거더와 아연도금 강판을 볼트에 의해 일체화시키기 때문에 기존에 용접에 의해 제작된 철선일체형 데크 플레이트에 비해 친환경 및 우수한 공법으로 인정받고 있다. 본 연구에서는 에코 데크 플레이트의 구조적 거동을 평가하기 위해 12가지 형태의 시험체를 동일한 조건으로 2개씩 총 24개의 시험체를 실물크기로 제작하여 실험적 연구를 수행한다. 실험결과 시공하중 작용에 대한 허용 처짐은 설계값 이내의 값을 나타내 만족하는 것으로 나타났으며, 래티스 철선의 가공은 아래로 향하게 절단해 제작하는 것이 구조적으로 유리한 것으로 나타났다. 또한, 하부철선으로 D13을 사용한 시험체의 경우에는 하부철선과 래티스 철선의 용접부위에서 파괴가 발생해 공장 제작 시 용접에 대한 개선안의 마련이 필요하다. Eco deck plate system is a construction method that deconstruction of galvanized steel sheets is possible by integrating steel-wire-integrated girders and the galvanized steel sheets with bolts. Therefore, compared with previous steel-wire-integrated deck plates which were joined by welding, the system is acknowledged as the construction method possible management and repair. This study conducted an experimental research by manufacturing total 24 full size specimens in a same condition for 12-shape specimens by two parts to evaluate structural behaviors of the eco deck plates. In the results after the test, permissible deflection for the construction load action was shown to be values under design values and satisfactory. The processing of lattice steel wires was presented to be structurally advantageous in being manufactured by cutting downward. Also, in case of a specimen that D13 as a steel wire was used, destruction occurred at the welding part of the bottom steel wire and the lattice steel wire, so improvement measures for the welding in factory manufacture are necessary.
