摘要： PROBLEM TO BE SOLVED: To provide an openable door with smoke insulation performance, which ensures high smoke insulating performance by maintaining the sealing performance of a rubber packing with respect to the door, prevents exposure of the rubber packing even under normal conditions, i.e. when door main bodies are opened, exhibits good appearance, and protects the rubber packing from being excessively pressed at the time of rotation of the door main bodies.
SOLUTION: The openable door is formed of the axially supported door main bodies 4a, 4b, and a door frame 3 enclosing the openable door main bodies 4a, 4b when closed. The door frame 3 has a frontage forming portion 3a extending in parallel with the door main bodies 4a, 4b in a closed position, and the frontage forming portion 3a has a protrusion 7 formed at a rear edge thereof in a manner extending an inner peripheral surface of the frontage forming portion 3a. The protrusion has a right-triangular cross section. Further the protrusion 7 has mounted thereon the rubber packing 9 which is formed of a rubber plate band, in a manner protruding from a corner of the protrusion 7. Thus the rubber packing abuts on the door main bodies 4a, 4b at a location of a face plate 10 inside the periphery of the door main bodies 4a, 4b when they are closed. Further an outer corner portion of each of the door main bodies 4a, 4b, closer to an axially supported location, has a tapered chamfer portion 11 by notching.
