To provide a slide-type fire door which can suppress the expansion of a gap with a door body due to the expansion of a middle rail and suppress the reduction in a pressing function of the door body by the middle rail.SOLUTION: The fire door comprises: an outer frame 10; a door body 4; and a middle rail 20. The middle rail 20 is arranged so as to overlap a target region in a wall orthogonal direction Z view and extend in the width direction X over a first frame part and a second frame part on the side opposite to the side of a wall body 2 with respect to the target region. The middle rail 20 and the first frame part are fixed to each other. The middle rail 20 is engaged with the second frame part via an engagement mechanism 30. The engagement mechanism 30 allows the relative movement in the width direction of the middle rail 20 with respect to the second frame part and regulates the relative movement in the wall orthogonal direction and the slide direction.SELECTED DRAWING: Figure 7
【課題】中桟の膨張による扉体との隙間の拡大を抑制し、中桟による扉体の押さえ機能の低下を抑制することができるスライド式の防火扉を提供する。【解決手段】防火扉は外枠10と扉体4と中桟20とを備え、中桟20は、壁直交方向Z視で対象領域と重複すると共に、対象領域に対して壁体2の側とは反対側において第一枠部と第二枠部とに亘って幅方向Xに延在するように配置され、中桟20と第一枠部とが互いに固定され、中桟20と第二枠部とが係合機構30を介して係合され、係合機構30は、中桟20の第二枠部に対する幅方向の相対移動を許容すると共に壁直交方向及びスライド方向の相対移動を規制する。【選択図】図7
