In the event of an outdoor fire, the first thermal expansion refractory material 11 thermally expands toward the indoor side when reaching the thermal expansion temperature, and closes the lower end of the hanging vertical stile 34 in the hollow portion 341A. Here, the resin cap 45 may melt and come off from the metal stile material 341 of the hanging vertical stile 34, but the first thermal expansion refractory material 11 also thermally expands downward to a certain extent, so that it can be attached to the hanging vertical stile 34 and below. It also closes the space between it and the frame main body part 221. Further, when the third thermal expansion refractory material 13 reaches the thermal expansion temperature, it thermally expands downward, closes the space between the lower frame 32 and the lower frame 22, and the first thermal expansion refractory material 11 thermally expands. This also indirectly improves the shielding condition between the hanging vertical stile 34 and the lower frame 22.
Following the thermal expansion of the first thermal expansion refractory material 11 and the third thermal expansion refractory material, the second thermal expansion refractory material 12 thermally expands toward the outdoor side when reaching the thermal expansion temperature, and the door stile 33 and the lower end of the hanging vertical stile 34 while blocking the space between the lower end and the door body receiving part 222, and connecting the lower stile 32, the door end vertical stile 33, the hanging vertical stile 34, and the lower frame main body part 221. close the gap between Further, the second thermally expandable refractory material 12 is also connected to the thermally expanded third thermally expandable refractory material 13 in the Z-axis direction, thereby improving the shielding state between the lower frame 32 and the lower frame 22.
In this way, the space between the lower part of the door body 3 and the lower frame 22 is closed by the first thermal expansion refractory material 11, the second thermal expansion refractory material 12, and the third thermal expansion refractory material 13.
