STEPPED WINDOW
To suppress generating of a connecting passage extending between indoor and outdoor spaces, in a stepped window including at its upper stage a sash that is opened and closed, between a transom and an upper stage sash in the event of fire.SOLUTION: A sash is supported, above a transom 15, in an openable/closable manner via an opening/closing mechanism 82, a thermally expansible material f151 is disposed on the indoor side of the opening/closing mechanism on the upper surface of the transom, concurrently a thermally expansible material f221 is disposed on the indoor side of the opening/closing mechanism on the lower surface of a lower frame 22 of the sash, and a thermally expansible material f222 is disposed on the outdoor side of the opening/closing mechanism on at least one of the upper surface of the transom and the lower surface of the lower frame 22.SELECTED DRAWING: Figure 6
【課題】上段に開閉する障子を備える段窓において、火災時における無目と上段の障子との間に、室内外に連通する連通路の発生を抑制する。【解決手段】無目１５の上方に開閉機構８２を介して障子が開閉自在に支持されており、無目の上面の開閉機構の室内側に加熱膨張材ｆ１５１が配置されているとともに、障子の下框２２の下面の開閉機構の室内側に加熱膨張材ｆ２２１が配置されており、無目の上面もしくは下框の下面の少なくとも一方において、開閉機構の室外側に加熱膨張材ｆ２２２が配置されている。【選択図】図６
