PROBLEM TO BE SOLVED: To provide a door device of a highly earthquake-resistant partition device that prevents support posts located on both sides of a door structure comprising a door frame and a door panel from influencing each other through the door frame and the door panel, thereby preventing two-stepped lifting force from being exerted on a panel plate adjacent to the door structure, even when a large-scale interlayer displacement takes place at a time of earthquake.SOLUTION: An earthquake-resistant partition device has a plurality of support posts erected at a prescribed interval between earthquake-resistant suspended ceiling structure and floor structure, and a door frame disposed between the prescribed support posts for supporting a door panel, thus configuring a door structure. With the partition device, both vertical door frame materials 11 of a door frame 7 are retained on a support post 5 in a way that allows upward displacement, thereby preventing lifting force from being exerted on the support post on one side to the support post on the opposite side through the door frame and the door panel, even when the support post is locked at a time of earthquake.SELECTED DRAWING: Figure 4 |
