DOOR FRAME MOUNTING DEVICE IN HIGH SEISMIC RESISTANCE PARTITION DEVICE

To provide a door frame mounting device that can return the door structure to an initial position and prevent cumulative lifting of the door frame and preventing falling off the support post even if the lower end of the vertical door frame of the door frame is lifted above the retaining bracket due to the interlayer displacement during a large earthquake, in a high seismic resistance partition device consisting of panel structure and door structure.SOLUTION: By the door frame 7 being guided by the holding fixture 13 and returning to the initial position, the door structure is also returned to the initial position by engaging the vertical door frame 11 constituting the door frame 7 with the column 5 so as to be capable of being displaced upward, and the lower end portion of the vertical door frame 11 is prevented from riding on the holding fixture 13 installed on the floor structure when the column 5 locks during an earthquake.SELECTED DRAWING: Figure 3 【課題】パネル構造体とドア構造体よりなる高耐震性間仕切装置において、大きな地震時の層間変位により、ドア枠の縦ドア枠の下端が保持金具より上に持ち上がっても、ドア構造体を初期位置に復帰させ、ドア枠の累積的なせり上がりを防ぎ支柱からの脱落を防止することができるドア枠取付装置を提供する。【解決手段】地震時に支柱５がロッキングした際に、支柱５に対してドア枠７を構成する縦ドア枠１１を、上方変位可能に係止するとともに、縦ドア枠１１の下端部をフロア構造体に設置した保持金具１３に乗り上げないようにし、ドア枠７が保持金具１３で案内されて初期位置に復帰することで、ドア構造体も初期位置に復帰させる。【選択図】図３
