The stopper 54 is fixed by a fixing member 910 to the reinforcing plate 55 and the collar frame 13 (14). Specifically, the reinforcing plate 55 is formed of a non-combustible material, for example, a metal material such as stainless steel, and the collar frame 14 (13) (a metal such as an aluminum alloy) is fixed to the collar frame 14 (13) of the sash frame 1 by a fixing means. It is fixed to the eaves frame 141 and the like by fixing means.
For this reason, in the event of a fire, the rod 54 provided on the outer cover 2 is reliably supported by the stopper 54 provided on the reinforcing plate 55 made of noncombustible material until the frame 14 is completely melted. Can do. That is, it is possible to provide the raising / lowering window 100 that can securely fix the external shoji 2 to the upper part of the sash frame 1 even during a fire.

  Further, the reinforcing plate 55 has a structure arranged in close contact with the collar frame 14 (13) of the sash frame 1, and the heat conduction between the reinforcing plate 55 and the collar frame 14 (13) is good, Since the heat dissipation is improved, the heat of the sash frame 1 can be radiated well in the event of a fire.

In addition, the reinforcing plate 55 is formed in an elongated plate shape and is formed in an L-shaped cross section, and more specifically, the outdoor portion having a shape bent from the outdoor side end of the plate portion 55a to the inside of the sash (center side). Since the side plate portion 55b is included, the outdoor side plate portion 55b further improves the reinforcing strength and heat dissipation.
In detail, the following can be mentioned as an effect which provided the reinforcement board 55. FIG.
(1) The reinforcing plate 55 has an outdoor side plate portion 55b provided along the inner surface of the rib frame protrusion 14a, and the outdoor plate portion 55b reinforces the rib frame protrusion 14a. Can do. For this reason, it is possible to reinforce the outer panel guide groove 14U constituted by the protrusion 14a and the protrusion 14b, and the outdoor plate portion of the reinforcing plate 55 even when the frame is heated during a fire. It is possible to reduce the occurrence of a gap between the outer panel 2 and the collar frame by the outer panel guide groove 14U reinforced by 55b.
(2) For example, in the case of an outdoor fire, even when the outdoor ridge 14a of the outer frame guide groove 14U of the frame 1 of the frame 1 is melted, the remaining reinforcing plate 55 and the outdoor plate 55b The ridge of the external shoji 2 can be held by the strip 14b.
(3) Since the thermal expansion refractory material 9 is provided on the reinforcing plate 55, the thermal expansion refractory material 9 expands in the event of a fire. It is possible to prevent a gap from being generated between the heel and the heel frame.
