In FIG. 11, the longitudinal cross-sectional view of the upper gutter 20 at the time of fire outbreak is shown. FIG. 11 (a)
This represents a stage where the heating foam 29 starts to foam when a fire occurs. Upper guide part 23 of the upper arm 20
The heating foam material 27 arranged inside fills the inside of the upper guide portion 23, and the heating foam material 28 arranged inside the hollow portion 21c of the upper collar 20 fills the inside of the hollow portion 21c.

The heating foam material 29 provided on the interior side surface of the metal upper casing 21 rises in temperature through the metal upper casing 21 in the event of a fire, and starts to foam when it reaches a predetermined temperature, for example, about 200 ° C. The foaming direction is the direction in which the heated foam material 29 faces, that is, foaming toward the indoor side, and the volume expands.
Since there is a gap between the interior side surface of the metal upper collar 21 on which the heating foam material 29 is provided and the resin upper collar 22, the foam-side tip of the heating foam material 29 is on the resin as shown in FIG. The heated foam 29 continues to expand until it reaches the heel 22. Since the heating foam material 29 is provided on the metal upper casing 21, heat is easily transmitted in the event of a fire, and foaming starts at an early stage.

If the fire continues until the heated foam 29 reaches the resin upper shell 22, the heated foam 29 further continues to foam. Since the maximum foaming width of the heating foam material 29 is larger than the width of the gap between the indoor side surface of the metal upper collar 21 and the resin upper collar 22, the resin upper collar 22 is pressed toward the indoor side by the heating foam material 29. Is done. When the temperature rises, the resin upper collar 22 softens, so the upper engagement portion 2
The engaging force of 2a and the lower engaging portion 22b with respect to the metal upper collar 21 decreases. In addition to this, when the resin upper collar 22 is pressed to the indoor side by the heating foam material 29, as shown in FIG. 11B, the resin upper collar 22 falls to the indoor side.

Even if the heating foam material 29 is not present, the resin upper casing 22 will eventually fall from the metal upper casing 21 as time elapses from the occurrence of the fire, but the heating foam 29 is placed between the metal upper casing 21 and the resin upper casing 22. By providing and pressing the resin upper casing 22 to the indoor side by the heating foam material 29, the resin upper casing 22 can be reliably dropped from the metal upper casing 21 relatively early in the event of a fire. The resin upper collar 22 that has dropped from the metal upper collar 21 to the indoor side is less likely to receive flames and heat directly, and therefore can be prevented from igniting. Thereby, the fireproof performance of the sash can be improved.

Although the heating foam material 29 is attached to the indoor side surface of the metal upper collar 21 in this embodiment, it may be disposed between the metal upper collar 21 and the resin upper collar 22, and the opposing surface portion 22 d of the resin upper collar 22. It may be attached to. Further, in the present embodiment, the heating foam material 29 is provided through substantially the entire length of the upper collar 20, but it is sufficient that a force for dropping the resin upper collar 22 at an early stage can be generated. A plurality of 29 may be provided along the longitudinal direction. Furthermore, in the present embodiment, the heating foam material 29 is provided on the upper part of the indoor side surface of the metal upper collar 21, but if it is an area between the metal upper collar 21 and the resin upper collar 22, It may be provided.
