Since it is latched by the folding | returning recessed part 115d of the upper frame 11 which is not received directly, or the smoke returning recessed part 143d of the left vertical frame 14, it can prevent that the one-way sliding door 3 falls to the outdoor side.

  Further, since the stainless steel reinforcing material that reinforces the hanging piece 331c and the bent piece 334c of the sliding door 3 is fixed to the steel plates 32a and 32b and the steel reinforcing materials 34a and 34d constituting the sliding door 3, the entire opening is a steel member. Since it is covered with the thermally expanded refractory material, it is possible to prevent the spread of fire and the intrusion of smoke from the opening.

The piece to be reinforced with the stainless steel reinforcing material is not limited to the hanging piece 331c or the bent piece 334c of the single sliding door 3, but depending on the situation of the place where the fireproof sliding door is installed, the vertical upper piece 115a of the upper frame 11 or the left vertical The bent piece 143b of the frame 14 may be reinforced, or both may be reinforced.
Further, the folding recess 115d of the upper frame 11 and the smoke returning recess 143d of the left vertical frame 14 are open toward the outside of the sliding door (upward, door-end direction), but are provided on the door tip side, for example. In some cases, the recess provided in the frame may be opened toward the inside of the sliding door.
