On the other hand, the summoning department operates as follows.
First, as the temperature of the aluminum fireproof attachment 70 rises, the thermally expanded refractory materials 6 to 8 provided in the attachment main body 71 thermally expand as shown by a two-dot chain line in FIG. 6, the space between the first finding piece 73 and the receiving surface 68 </ b> A of the reinforcing finding piece 68 is closed, and the space between the second finding piece 74, the outdoor finding piece 81 and the pushing edge 88 is blocked by the thermal expansion refractory material 7. The space between the extended piece 77 and the indoor finding piece 55 is blocked by the thermal expansion refractory material 8. In this way, the space between the outer summon basket 33 and the inner summit basket 44 is quickly closed by the thermally expanded refractory materials 6-8.
Next, each thermal expansion refractory material 5 provided on the reinforcing members 60 and 65 is thermally expanded by the temperature rise of the outer summon bowl 33 to fill the hollow portion 50 </ b> A and the concave groove forming portion 53. Here, since the refractory attachment 70 is fixed to the reinforcing member 65, even if the outer summing body 50 is softened due to a temperature rise, it keeps a predetermined position without being detached from the outer summoning basket 33. The outer peripheral prospective piece 54 is kept from being exposed to the flame.
Thus, at the time of an outdoor fire, the thermal expansion refractory materials 5 to 8 are thermally expanded to block the interior and the exterior.

In the event of an indoor fire, the thermal expansion refractory material provided on the upper frame 21, the lower frame 22, the left and right vertical frames 23, 24, the upper rods 31, 41, the lower rods 32, 42 and the vertical rods 34, 43 in the same manner as described above. (Illustration omitted) is thermally expanded by heat at the time of fire and shuts off the interior and the exterior. On the other hand, the summoning department operates as follows.

[Effect of the first embodiment]
(1) In the first embodiment, the sliding window 1 has a fireproof attachment 70 fixed to the reinforcing member 65 of the outer summoning basket 33, and the fireproof attachment 70 is composed of the outer summoning basket 33 and the inner summoning. An attachment main body 71 disposed between the flanges 44, and a cover that extends from the attachment main body 71 to the outdoor side and covers a prospective surface that is an outer surface of the outer peripheral prospective piece 54 of the outer summing main body 50 The thermal expansion refractory materials 6 and 7 are provided on the outdoor surface of the attachment main body 71, and the thermal expansion refractory material 8 is provided on the indoor surface of the attachment main body 71. It is characterized by. Since it has the above-described configuration, the fireproof attachment 70 fixed to the reinforcing member 65 can be kept in its position without coming off in the event of a fire, and the thermal expansion refractory materials 6 and 8 are thermally expanded by the heat of the fire. The space between the main body 71 and the outer summoning basket 33 can be blocked, and the thermal expansion refractory material 7 is thermally expanded by the heat of the fire, so that the space between the attachment main body 71 and the inner summoning basket 44 can be blocked. In addition, it is possible to reduce the risk of a flame entering between the outer summon bowl 33 and the inner summit bowl 44. Furthermore, compared with the case where the prospective surface of the outer peripheral prospective piece 54 of the outer summoning bowl 33 is not covered by the cover piece 72, the prospective face is not exposed to the flame. It is possible to suppress the temperature rise and make it difficult to burn out.
(2) The reinforcing member 65 and the fireproof attachment 70 are made of a material having a melting point higher than that of the resin outer summing body 50, and the reinforcing member 65 has a receiving surface 68A along the X-axis direction. The thermal expansion refractory material 6 is disposed on the indoor side with respect to the receiving surface 68A. For this reason, the thermal expansion refractory material 6 is thermally expanded from the attachment main body 71 toward the receiving surface 68A, so that the space between the attachment main body 71 and the outer summoning bowl 33 is smaller than when there is no receiving surface 68A. It can be blocked more reliably.
(3) The fireproof attachment 70 is made of a material having a melting point higher than that of the resin inner summing body 80 and the resin pushing edge 88, and the thermal expansion refractory material 7 includes the inner summing body 80 and the pushing edge 88. It faces the position that straddles both sides. For this reason, the thermal expansion refractory material 7 is thermally expanded from the attachment main body 71 to the indoor side in the event of a fire, thereby closing the space between the attachment main body 71 and the inner summing main body 80, and The seam can be covered, the invasion of the flame from the joint of the inner summing body 80 and the press lip 88, the softening of the press lip 88, and the falling off due to melting can be suppressed, and even if the press lip 88 is burned out The portion where the pressing edge 88 was present can be filled with the thermally expanded refractory material 7.
(4) The fireproof attachment 70 forms a hollow portion 76 by the cover piece portion 72, the first finding piece portion 73, the second finding piece portion 74, and the connecting piece portion 75, and the thermal expansion refractory material 6 is found first. The thermal expansion refractory material 7 is provided in the piece 73, and is provided in the second finding piece 74 that is located on the indoor side with respect to the first finding piece 73. For this reason, compared with the case where the thermal expansion refractory materials 6 and 7 are provided in the outdoor surface and indoor surface of one finding piece part, for example, the intensity | strength of the attachment main-body part 71 can be raised, and the thermal expansion refractory material 6 Can be placed close to the indoor surface of the outside summoning bowl 33 and the thermally expanded refractory material 7 can be placed close to the outdoor surface of the inside summoning bowl 44, so that in the event of a fire, The space between the attachment main body 71 can be quickly closed by the thermal expansion of the thermally expanded refractory materials 6 and 7.
(5) Since the thermal expansion refractory materials 6 and 8 are provided in the first finding piece portion 73 and the extension piece portion 77, compared with the case where only one of the thermal expansion refractory materials 6 and 8 is provided, In the X-axis direction, it is possible to increase an area for closing the space between the outside summoning basket 33 and the attachment main body 71 during a fire. Further, for example, in the case of an outdoor fire, the thermal expansion refractory material 6 provided in the first finding piece portion 73 can be thermally expanded by increasing the temperature before the thermal expansion refractory material 8 provided in the extension piece portion 77.
