-FIX window configuration-
As shown in FIGS. It has a frame composed of attachments 55 and 56, and a panel 35 such as glass fitted in the inner circumference of the frame.
The configurations of the transom light 15, the lower frame 12, and the left and right vertical frames 13 and 14 are as described above.

As shown in FIG. 4, the left and right lower attachments 55 and 56 have the same cross-sectional shape (hereinafter, mainly described with reference to the “left lower attachment 55”), and the prospect wall 55a and the prospect wall 55a. The indoor side legs 55b extending in the outer peripheral direction from the indoor outer peripheral surface of 55a, the outdoor side legs 55c extending in the outer peripheral direction from the outdoor side outer peripheral surface of the prospect wall 55a, and the outdoor side of the prospect wall 55a.

Thermal expansion materials f55 and f56 that expand due to heating during a fire are arranged in the lower portion.

As described above, by arranging different attachments above and below the transom 15 with respect to the left and right vertical frames 13 and 14 of the frame 1, different types of windows can be easily arranged above and below the transom 15. be able to.
By the way, among the windows in which the attachments are arranged on the inner circumferences of the left and right vertical frames 13 and 14, the FIX windows arranged at the lower positions of the step windows of the present embodiment are shown in FIGS. 7 (a) and 7 (b). ), The lower attachments 55 and 56 rotate with respect to the left and right vertical frames 13 and 14 due to a strong external force (positive pressure or negative pressure) applied to the panel 35 due to wind or the like, and the lower attachments 55 and 56 are detached or damaged. There is a risk of spilling.

In the stepped window of the present embodiment, the attachments are attached to the left and right vertical frames 13 and 14 by providing a rotation restricting structure on the window formed by arranging the attachments on the inner circumferences of the left and right vertical frames 13 and 14. It prevents it from rotating and coming off or being damaged.
Hereinafter, a specific configuration will be described with reference to the left vertical frame 13 and the lower attachment 55 of the FIX window portion.

In the stepped window of the present embodiment, as shown in FIG. 5, the FIX window portion is found on the indoor side of the left vertical frame 13 formed by arranging the lower attachment 55 on the inner circumference of the left vertical frame 13. A rotation restricting member 91 is arranged between the wall 13b and the indoor side leg portion 55b of the lower attachment 55.

The rotation restricting member 91 is, for example, a piece-shaped member made of a hard resin material, and is attached to the vertical frame 13 in advance with double-sided tape or the like, and the lower attachment 55 is attached from the inner peripheral side to the indoor side finding wall 13b and the outdoor side. By inserting it between the finding wall 13c, it can be arranged between the indoor side finding wall 13b of the left vertical frame 13 and the indoor side leg portion 55b of the lower attachment 55.

If necessary, the rotation restricting member 91 may be fixed to the vertical frame 13 and the lower attachment 55 from the indoor side surface of the indoor side finding wall 13b of the left vertical frame 13 by a fixing means b1 such as a screw.
Further, the rotation restricting member 91 may be a long member.

Further, the lower attachment 55 is positioned on the outdoor side of the prospective wall 55a of the lower attachment 55 in the prospective direction, specifically, at a position between the outdoor side leg 55c and the airtight leg 55d of the prospective wall 55a. It is fixed to the prospective wall 13a of the left vertical frame 13 from the inner peripheral side of the above by a fixing means b2 such as a screw.

As described above, the FIX window portion of the present embodiment has the indoor side finding wall 13b of the left vertical frame 13 and the indoor side leg portion 55b of the lower attachment 55 on the indoor side of the left vertical frame 13 and the lower attachment 55. By providing the rotation restricting member 91 between them, when a force X1 for rotating the lower attachment 55 is generated by the negative pressure shown in FIG. 7A, the indoor side surface of the indoor side leg 55b of the lower attachment 55 is restricted from rotating. It is possible to prevent the lower attachment 55 from rotating further by contacting the member 91 and prevent the lower attachment 55 from coming off.

Further, on the outdoor side of the left vertical frame 13 and the lower attachment 55, the left vertical is provided between the outdoor side leg portion 55c and the airtight leg portion 55d from the inner peripheral side of the prospective wall 55a of the lower attachment 55 by a fixing means b2 such as a screw. By fixing to the frame 13, the rotation X2 of the lower attachment 55 due to the positive pressure shown in FIG. 7B can be suppressed by the fixing means b2.

The rotation control structure provided on the indoor side of the left vertical frame 13 and the lower attachment 55 is arranged between the indoor side finding wall 13b of the left vertical frame 13 and the indoor side leg portion 55b of the lower attachment 55. It is not limited to the separate rotation restricting member 91, and may be integrally provided on the indoor side of the lower attachment 55.

For example, as shown in FIG. 6, a rotation restricting portion 55g that abuts on the outdoor side surface of the indoor side finding wall 13b of the left vertical frame 13 is provided at the outer peripheral end of the indoor side leg portion 55b of the lower attachment 55, and the left vertical is provided. By fixing the indoor side finding wall 13b of the frame 13 and the indoor side leg portion 55b of the lower attachment 55 with a fixing means b1 such as a screw, the rotation X1 of the lower attachment 55 due to the negative pressure shown in FIG. 7A is suppressed. You may do so.

As described above, the stepped window of the present embodiment is provided with a structure for preventing the rotation of the attachment on the indoor side and the outdoor side between the vertical frame and the attachment, so that either the negative pressure or the positive pressure generated in the stepped window is provided. The rotation of the attachment can be regulated against external force, and damage to the attachment and detachment of the panel can be suppressed.

In particular, the rotation regulation structure by the rotation regulation member 91 arranged between the indoor side finding wall 13b of the left vertical frame 13 and the indoor side leg portion 55b of the lower attachment 55 requires processing of the vertical frame and the lower attachment itself. However, it can also be applied to existing stepped windows.
Further, by arranging the rotation restricting member 91 at a necessary portion according to the size of the window, it is possible to achieve the necessary and sufficient rotation regulation of the lower attachment without excessively processing the lower attachment.

Further, even in the event of a fire, the rotation regulation structure suppresses the rotation generated by the warp of the attachment, and thus the fire protection performance can be expected to be improved.
Further, the rotation restricting member 91 may be formed of a metal material, which can be expected to further improve the fire protection performance.

Further, the window type in which the rotation regulation structure of the above embodiment is arranged is not limited to the FIX window, and can be adopted for all window types. Further, it may be adopted at the vertical position (horizontal frame portion) of the window.
It goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
