あるだけであるから、その扉を構成する上框、下框、縦
框は熱伸びに対して抱束されずに熱伸びする。縦框の長
さは上框、下框の長さの3〜4倍程度であるから縦框の
熱伸びが大きい。Since the hinged door is attached to the opening of the building by screwing the door frame or by supporting the anchor, the upper frame, the lower frame and the vertical frame constituting the door frame are resistant to thermal expansion. Be hugged. Since the door is only attached to the door frame with a flag hinge, the upper frame, the lower frame, and the vertical frame that compose the door expand without being bound by the heat expansion. Since the length of the vertical frame is about 3 to 4 times the length of the upper frame and lower frame, the thermal expansion of the vertical frame is large.
【0004】このために、火災時に扉が加熱されて熱伸

に変形する。For this reason, when the door is heated and expands during a fire, the upper part of the door contacts the inner surface of the upper frame and the lower part of the door contacts the inner surface of the lower frame. When the door is further heated from this state and tries to thermally expand, the upper part of the door 1 contacts the inner surface 2a of the upper frame 2 and the lower part of the door 1 contacts the inner surface 3a of the lower frame 3 as shown in FIG. Therefore, the door 1 cannot be straightly expanded in the vertical direction, and the upper and lower parts are deformed in a dogleg shape so as to project to the opposite side to the airtight material mounting portion 4 with the upper and lower intermediate portions as boundaries. .
