As shown in FIG. 2, the smoke return piece 72 formed on the indoor side surface of the right stile 34 is attached to the upper portion and the airtight material mounting piece 121e of the lower frame 2 that interfere with the central found wall portion 111d of the upper frame 11. The lower part that interferes has been removed.

Then, in the fireproof fitting of the present embodiment, the structure of the inner and outer shoji 2 and 3 merging parts is devised, and the heated foaming materials f41 and f42 are arranged in the merging part, so that the interior of the merging part is indoors. It suppresses outside communication.
Hereinafter, the configuration of the combined portion of the inner and outer shoji 2 and 3 will be further described with reference to FIG.

As shown in FIG. 4A, the left stile (combination stile) 23 of the internal shoji 2 has a rectangular hollow shape of the left stile main body 231a and dimensions in the prospective direction from the left stile main body 231a. Has a large glass frontage portion 231b, and the outdoor side surfaces of the left rectangular main body portion 231a and the glass frontage portion 231b are formed substantially flush with each other.
The found size A of the sash 23 of the internal shoji 2 of the present embodiment is formed to be relatively large, and has a found size of about 40 mm as an example.

In the left stile 23, the prospective wall 231c that separates the left stile main body 231a and the glass frontage 231b protrudes from the flush outdoor surface to the outdoor side, and then bends to the inner peripheral side, and the glass frontage 231b A smoke return piece 71 is formed along the outdoor side. The indoor side surface of the smoke return piece 71 is formed as an inclined surface toward the outdoor side toward the inner circumference.

The airtight material s4 is arranged on the outdoor side surface on the outer peripheral side of the left stile main body 231a, and the heat foaming material f41 is arranged between the airtight material s4 and the smoke return piece 71.

The right stile (combination stile) 34 of the outer sash 3 has a right stile main body 341a having a rectangular hollow shape and a glass frontage 341b having a larger dimension in the prospective direction than the right stile main body 341a. The interior side surfaces of the right rectangular main body portion 341a and the glass frontage portion 341b are formed substantially flush with each other. The sash 34 of the outer sash 3 and the sash 23 of the inner sash 2 have substantially the same found width dimension A, and the cross-sectional shapes of the vertical stile body and the glass frontage are substantially the same. Is formed in.

In the right stile 34, the outer peripheral wall 341c of the right stile main body 341a protrudes from the indoor side to the indoor side and then bends to the inner peripheral side, and a smoke return piece is formed along the indoor side of the right stile main body 341a. 72 is formed. The indoor side surface of the smoke return piece 72 is formed as an inclined surface toward the indoor side toward the inner circumference.

Then, the allowance between the smoke return piece 71 of the inner shoji 2 and the smoke return piece 72 of the outer shoji 3 (for example, the inclined surface of the smoke return piece 71 of the inner shoji 2 and the smoke return of the outer shoji 3) constituting the smoke return 7. The found dimension x1 of the contact portion of the inclined surface of the piece 72) has at least one-third or more of the found width dimension A of the sashes 23 and 34 of the outer sashes 2 and 3 for comparison. It forms a large amount of smoke.

A recess 341d is formed on the indoor side surface of the right stile main body 341a, and the heated foaming material f42 is arranged in the recess 341d.
As shown in FIG. 4B, the recess 341d formed on the indoor side surface of the right stile main body 341a is a surface substantially perpendicular to the indoor side surface, and is an outer peripheral surface forming a wall surface on the outer peripheral side of the recess 341d. It has 341e, an inner peripheral surface 341f that inclines from the outdoor side to the indoor side as it goes from the outer peripheral side to the inner peripheral side, and a bottom surface 341 g that is a surface parallel to the indoor side surface of the right stile main body 341a. The inner peripheral surface 341f is located on the inner peripheral side of the smoke return piece 72 with respect to the inner peripheral side end.

When arranging the heated foaming material f42 on the indoor side surface of the right stile main body 341a, the heated foaming material f42 is inserted from the inclined inner peripheral surface 341f side of the recess 341d until it reaches the outer peripheral surface 341e to return smoke. The heated foaming material f42 can be positioned and arranged on the outdoor side of the piece 72.

As shown in FIGS. 5A and 5B, the heated foaming material f42 arranged on the indoor side surface of the right stile main body 341a may be arranged on the entire length of the right stile 34 in the longitudinal direction, but FIG. As shown in (c), it may be arranged only in the upper and lower portions including the portion where the lower stiles 31 and 32 are connected to the upper stile 34.

As described above, in the fire-prevention fitting of the present embodiment, the finding size of the sash for the inner and outer sashes is made large, and the finding size of the smoke return allowance formed in the sash is included. Since the size is 1/3 or more of the found size of the shoji shoji, even if the mating part is deformed due to the extension of the upper and lower stiles in the event of a fire, the smoke return pieces are hard to disengage. It is possible to maintain the state of cooperation between the inner and outer shoji screens, and it is possible to suppress the communication between indoors and outdoors at the meeting part.

Furthermore, by arranging a heated foam material near the smoke return in the upper and lower parts of the vertical stile, which is likely to be deformed due to the extension of the upper and lower stiles in the event of a fire, the upper and lower parts of the smoke return, which are likely to have gaps due to deformation, are heated foam material. It is possible to prevent communication between indoors and outdoors of the mating part even in a fitting having a relatively large vertical dimension.

In addition, a recess is formed in the portion where the heated foam material is arranged in the mating portion, and one side surface of the recess is a vertical wall and the other side wall is an inclined surface, so that the heated foam material is arranged and positioned. Can be smoothed.

In each embodiment, the heated foaming material attached to the frame is held by the recess formed in the frame or the frame, but the arrangement of the heated foam is not limited to the recesses, for example. It may be fixed by double-sided tape or adhesive, or may be fixed by screws or the like.
The recess for arranging the heated foaming material may be formed in a portion other than the mating stile.

It goes without saying that the above embodiments do not limit the invention described in the claims and are treated as examples.
