As shown in FIG. 2, the smoke return piece 72 formed on the indoor side surface of the right vertical frame 34 is attached to the upper part of the upper frame 11 that interferes with the central finding wall 111 d and the airtight material attachment piece 121 e of the lower frame 2. The interfering lower part has been cut away.

In addition, in the fire prevention fitting of the present embodiment, the configuration of the combining portion of the inner and outer shojis 2 and 3 is devised, and the heating foam materials f41 and f42 are arranged in the combining portion, so that the indoor space in the combining portion is improved. Outside communication is suppressed.
Hereinafter, the configuration of the combining portion of the inner and outer shojis 2 and 3 will be further described with reference to FIG.

As shown in FIG. 4 (a), the left vertical frame (summing frame) 23 of the inner shoji 2 has a left vertical frame main body 231a having a rectangular hollow shape, and a dimension in an expected direction than the left vertical frame main body 231a. Has a large glass frontage 231b, and the outdoor side surfaces of the left vertical frame main body 231a and the glass frontage 231b are formed substantially flush.
It should be noted that the apparent size A of the summing frame 23 of the inner sash 2 of the present embodiment is formed relatively large, and has an apparent size of about 40 mm as an example.

  In the left vertical frame 23, a prospective wall 231c that partitions the left vertical frame main body portion 231a and the glass frontage portion 231b protrudes from the flush outdoor side surface to the outdoor side, and then bends to the inner peripheral side. 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 as going toward the inner periphery.

  An airtight material s4 is arranged on the outdoor side surface on the outer peripheral side of the left vertical frame main body 231a, and a heated foam material f41 is arranged between the airtight material s4 and the smoke return piece 71.

  The right vertical frame (summing frame) 34 of the outer sliding door 3 has a right vertical frame main body 341a having a rectangular hollow shape, and a glass frontage 341b having a larger dimension in the expected direction than the right vertical frame main body 341a. In addition, the indoor side surfaces of the right vertical frame main body 341a and the glass frontage 341b are formed substantially flush. The summing frame 34 of the outer shoji 3 and the summing frame 23 of the inner shoji 2 have substantially the same apparent width dimension A, and the cross-sectional shapes of the vertical frame main body and the glass frontage are substantially the same. Is formed.

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

  Then, the margin between the smoke return piece 71 of the inner sash 2 and the smoke return piece 72 of the outer sash 3 constituting the smoke return 7 (for example, the slope of the smoke return piece 71 of the inner sash 2 and the smoke return of the outer sash 3) The contact dimension of the inclined surface of the piece 72) The finding dimension x1 is at least one-third or more of the finding width dimension A of the summing frames 23, 34 of the inner and outer sliding doors 2, 3. It is forming a large cost.

A concave portion 341d is formed on the indoor side surface of the right vertical frame main body 341a, and a heated foam material f42 is arranged in the concave portion 341d.
As shown in FIG. 4 (b), the concave portion 341d formed on the indoor side surface of the right vertical frame main body 341a is a surface substantially perpendicular to the indoor side surface and forms the outer peripheral wall surface of the concave portion 341d. 341e, an inner peripheral surface 341f inclined from the outdoor side to the indoor side as going from the outer peripheral side to the inner peripheral side, and a bottom surface 341g which is a plane parallel to the indoor side surface of the right vertical frame main body 341a, The inner peripheral surface 341 f is located on the inner peripheral side of the inner peripheral end of the smoke return piece 72.

  When arranging the heating foam material f42 on the indoor side surface of the right vertical frame main body 341a, the heating foam material f42 is inserted from the inclined inner peripheral surface 341f side of the concave portion 341d to reach the outer peripheral surface 341e, thereby making a smoke return. The heated foam material f42 can be positioned and arranged on the outdoor side of the piece 72.

  As shown in FIGS. 5 (a) and 5 (b), the heated foam material f42 disposed on the indoor side surface of the right vertical frame main body 341a may be disposed over the entire length of the right vertical frame 34 in the longitudinal direction. As shown in (c), it may be arranged only on the upper and lower portions including the portion where the lower frames 31, 32 are connected to each other above the summing frame 34.

  As described above, in the fire prevention fittings of the present embodiment, the found size of the summing frame for the inner and outer shojis is made large, and the found size of the smoke return that is formed in the mating part is set to the inside. , Because it is 1/3 or more of the found size of the sumo frame of the shoji, even if the assembling part is deformed due to extension of the upper and lower frames during a fire, it is difficult for the smoke return pieces to disengage from each other. In addition, it is possible to maintain the cooperative state of the inner and outer sashes, and it is possible to suppress communication between the indoor and the outside at the combining unit.

  In addition, by placing the heating foam near the smoke return on the upper and lower parts of the vertical stile, which tends to be deformed due to the expansion of the upper and lower stairs in case of fire, the upper and lower parts of the smoke return, which are likely to have gaps due to deformation, are heated and foamed Thus, even in the case of a fitting having a relatively large vertical dimension, it is possible to prevent communication between the inside and outside of the fitting section.

  In addition, a concave portion is formed in a portion of the summing portion where the heated foam material is disposed, and one side surface of the concave portion is formed as a vertical wall and the other side wall is formed as an inclined surface, thereby disposing and positioning the heated foam material. Can be smoothed.

In each of the embodiments, the heating foam attached to the frame is held by the recess formed in the frame or the frame. However, the arrangement of the heating foam is not limited to the recess, for example, It may be fixed with a double-sided tape or an adhesive, or may be fixed with a screw or the like.
In addition, the recessed part in which the heating foam material is arranged may be formed in a portion other than the summing frame.

  It is needless to say that the above embodiments do not limit the invention described in the claims but are treated as examples.
