<p>A landing door of elevator provided with a reinforcing body (2) for enhancing the rigidity on the rear surface of a door panel (1). The landing door comprises an adhesive (3) for bonding the door panel (1) and the reinforcing body (2), and a thermal expansion agent (4) interposed between the door panel (1) and the reinforcing body (2). When high temperature is applied due to occurrence of fire, the thermal expansion agent (4) expands to separate the door panel (1) and the reinforcing body (2) and the door panel (1) can be prevented from being deformed due to difference in the coefficient of thermal expansion between the door panel (1) and the reinforcing body (2). Since the entrance/exit of the elevator can be enclosed surely by the door panel (1), smoke or flame can be prevented from intruding into the cage or the elevator shaft.</p> |
