SLIDING DOOR DEVICE FOR PARTITION WALL

To provide a sliding door device capable of preventing a panel plate from being forced up by allowing the vertical displacement of the panel plate upon an earthquake without being hindered by an installed sliding door, in an earthquake-resistant partition wall in which the panel plate is engaged displaceably in an upward direction with both or either of a front surface and a rear surface of a column erected with a predetermined interval between a ceiling rail and a floor rail by a locking tool, and locking positions can be displaced in a surface in accordance with the inter-layer displacement of upper and lower slabs.SOLUTION: In the sliding door device, a predetermined gap is formed between a rail member 30 and a panel plate 7 through a spacer member arranged at a joint part between the panel plates 7 or between an end member and the panel plate when the rail member 30 is laterally installed over a plurality of columns 6 to suspend an external sliding door 29 to open/close an entrance, the vertical displacement of the panel plate 7 is allowed when locking, and the relative displacement of the rail member 30 is allowed in an in-plane direction to the spacer member.SELECTED DRAWING: Figure 3 【課題】天レールと地レールとの間に所定間隔で立設した支柱の表裏両面又は片面に係止具にてパネル板を上方変位可能に係合し、上下スラブの層間変位に対して面内でロッキング変位可能としてなる耐震性間仕切壁において、設けられた引戸に阻害されず、地震時のパネル板の上下変位を許容してパネル板のせり上がりを防止することが可能な引戸装置を提供する。【解決手段】出入り口を開閉する外付けの引戸２９を吊支するレール部材３０を、複数の支柱６にわたって横設するに当り、パネル板７間の目地部、または端部部材とパネル板間の目地部に設けたスペーサ部材を介在させて、レール部材３０と前記パネル板７との間に所定の隙間を形成して取付け、ロッキング時に、パネル板７の上下変位を許容するとともに、レール部材３０のスペーサ部材に対する面内方向の相対変位を許容してなる。【選択図】図３
