The present invention relates to an elevator capable of blocking smoke in fire and, more specifically, to a platform door unit for an elevator having a smoke blocking structure without receiving interference on the operation of an elevator door normally, capable of blocking the diffusion of smoke between the elevator and the elevator shaft by perfectly blocking a gap between an elevator door and a door frame by the thermal expansion in the fire and specially, capable of stably blocking the smoke in the fire without receiving the interference on the close of the elevator door normally. The elevator comprises: a door frame formed on both sides and an upper of the exit of the elevator; an elevator door to control a platform and the open and close of the elevator shaft; and a doorsill to guide the open and close of the elevator by installing a guide shoe of the elevator door by being installed on the exit floor of the platform.
본 발명은 화재시 연기의 차단이 가능한 승강기에 관한 것으로, 더욱 상세하게는 평상시 승강장 도어의 작동에 간섭받지 않게 하면서도, 화재가 발생시 열에 의한 팽창으로 승강장 도어와 문틀과의 사이 간극을 완벽하게 차단하여 승강장과 승강기 샤프트간의 연기의 소통이 차단되게 하는 등 화재시 승강기 샤프트를 통한 연기의 확산을 차단하며, 특히 평상시에는 승강장 도어의 개폐에 간섭받지 않으면서 꼭 필요한 화재시에만 작동하여 차연이 가능하게 하는 등 안정적인 차연성능의 발휘가 가능하게 하기 위한 차연구조를 갖는 승강기의 승강장 도어 유닛에 관한 것이다.
