The present invention pertains to an elevator landing door system having a fire prevention device that prevents flame or smoke from penetrating into a shaft (60) from a landing and being spread throughout the entire building by blocking the gap between door panels (11, 11') when a fire breaks out in a building. The elevator landing door system having a fire prevention device consists of door panels (11, 11') that are opened and closed; a fire prevention plate (40) that extends alongside the opening and closing edge surface (11b) of one door panel (11) on the side (11b) facing the elevator, equipped with a downward slot (42) inclined toward the opening and closing edge of the door panel, and fixed to the door panel by a fastening means (46) penetrating through the slot; and fixtures (44) made of a fusible material that are tightly attached together with the door panel and the fire prevention plate by the fastening means. The fixtures (44) are arranged between the door panel (11) and the fire prevention plate (40) or between the fire prevention plate (40) and the fastening means (46) and are made of plastic or lead. |
