Next, the effect of the sash 1 concerning this Embodiment is demonstrated.
As shown in FIG. 1, even when the aluminum fence or frame 11 is melted by the heat of the fire, as shown in FIG. 1, the glass holding groove reinforcing material 25 made of a material having a higher melting point than aluminum, the lower iron reinforcing material 51, Since the lower stay 19 and the lower frame reinforcing member 52 are fixed in series by screws 50, 30, and 68, the glass 4 can be prevented from falling off.
Furthermore, even if the resin shape 6 of the aluminum resin composite shoji 3 burns out in the event of a fire, the fourth thermal expansion refractory material 32d provided on the lower frame 15 expands due to the heat of the fire, and the lower auxiliary plate of the lower lid 7 29 and the corner portion 7c, and closes the space between the lower collar 7 and the lower frame 15. Thereby, it is possible to prevent the outside air from entering the room from between the lower arm 7 and the lower frame 15 of the aluminum resin composite shoji 3 at the time of a fire, and blowing out the flame in the room to the outside.

上下左右の框5、7、9、9には、ガラス保持溝21内にスチール製のガラス保持溝補強材25が設けてあり、ガラス保持溝補強材25によりガラスの四周を保持しているので、火災時にアルミニウム製の框5、7、9、9及びグレイジングガスケット24が溶けた場合でもガラス4を保持して、ガラス4の脱落を防止できる。
