DOOR DEVICE OF HIGHLY EARTHQUAKE-RESISTANT PARTITION DEVICE

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 【課題】ドア枠とドアパネルからなるドア構造体の両側に位置する支柱に対して、ドア枠とドアパネルを介して相互に影響を及ぼさないようにして、地震時に大きな層間変位が生じても、ドア構造体に隣接するパネル板に二段階の持ち上げ作用が生じないようにした高耐震性間仕切装置におけるドア装置を提供する。【解決手段】耐震性の吊り天井構造体とフロア構造体との間に、複数の支柱を所定間隔で立設し、該支柱間にパネル板を装着してパネル構造体を構築するとともに、所定の支柱間にドアパネルを支持するドア枠を配置してドア構造体を構築してなる耐震性間仕切装置において、ドア枠７の両縦ドア枠１１を対応する支柱５にそれぞれ上方変位可能に保持し、地震時に支柱がロッキングしてもドア枠及びドアパネルを介して一方の支柱から反対側の支柱に持ち上がり力が作用しないようにした。【選択図】 図４
