The present invention relates to a reinforcing bar-integrated slab formwork unit for a hollow slab in which hollow balls, reinforcing bars, and a formwork are integrally assembled, which enables installation of reinforcing bar-integrated slab formwork units to contact each other and can embody lap splicing by having pull-out type spliced reinforcing bars instead of projected reinforcing bars in a reinforcing bar-integrated slab formwork unit for a hollow slab; a system formwork for a hollow slab which is completed by applying the slab formwork unit to a tunnel form, a flying form, etc.; and a hollow slab construction method wherein the system formwork is preferably used. La présente invention concerne une unité de coffrage de dalle à barres d'armature intégrées pour une dalle creuse, comprenant des billes creuses, des barres d'armature et un coffrage assemblés d'un seul tenant, ce qui permet l'installation d'unités de coffrage de dalle à barres d'armature intégrées de sorte à ce qu'elles soient en contact l'une avec l'autre et de mettre en œuvre un raboutage à recouvrement grâce à des barres d'armature raboutées de type amovible au lieu de barres d'armature saillantes dans une unité de coffrage de dalle à barres d'armature intégrées pour dalle creuse. L'invention concerne en outre un coffrage de système pour une dalle creuse qui est complété par application de l'unité de coffrage de dalle à un coffrage-tunnel, une table coffrante, etc.L'invention concerne enfin un procédé de construction de dalle creuse dans lequel le coffrage de système est de préférence utilisé. 본 발명은 중공볼, 철근, 거푸집이 일체로 조립된 중공 슬래브용 철근 일체형 슬래브 거푸집 유닛에서 돌출된 철근 대신 인출식 이음철근이 구비됨으로써 철근 일체형 슬래브 거푸집 유닛 상호 간을 맞대어 설치할 수 있으면서 겹침이음을 실현할 수 있는 중공 슬래브 용도의 철근 일체형 슬래브 거푸집 유닛과, 이러한 슬래브 거푸집 유닛이 터널폼, 플라잉폼 등에 적용되어 완성되는 중공 슬래브 용도의 시스템 거푸집, 그리고 이러한 시스템 거푸집을 바람직하게 이용한 중공 슬래브 시공방법에 관한 것이다.
