Abstract

Conventional floor formwork systems using timber and steel plates in bridge girder fabrication have limitations in reusability, leading to reduced construction efficiency and increased environmental burden. This study analyzes the field application performance of a modular composite floor formwork system and evaluates its carbon reduction effect through Life Cycle Assessment (LCA). Field application results show that the proposed system simplifies construction processes and improves work efficiency, resulting in reduced construction time, while ensuring structural stability and surface quality. In addition, LCA conducted in accordance with ISO 14067 confirms a reduction in carbon emissions compared to conventional formwork systems. The results demonstrate the technical and environmental applicability of modular composite floor formwork for sustainable bridge construction

기존 교량 거더 제작 공정에서 사용되는 각재 및 철판 기반 바닥거푸집은 재사용성 한계로 인해 시공 효율 저하와 환경 부하 증가 문제가 지적되어 왔다. 본 연구에서는 모듈식 복합소재 바닥거푸집을 대상으로 현장 적용 성능을 분석하고, 전과정평가(Life Cycle Assessment, LCA)를 통해 탄소저감 효과를 평가하였다. 현장 적용 결과, 시공 공정 단순화와 작업 효율 향상으로 공기 단축 효과가 확인되었으며, 구조적 안정성과 바닥면 품질 또한 우수하게 나타났다. 또한 ISO 14067 기준 LCA 분석을 통해 기존 각재·철판 거푸집 대비 탄소배출 저감 효과를 확인하였다. 본 연구는 모듈식 복합소재 바닥거푸집의 기술적·환경적 적용 가능성을 제시한다.
