(Fireproof structure with thermal expansion refractory material)
As shown in FIGS. , 221c, the upper auxiliary material 214, and the lower auxiliary material 224 form spaces S1 and S2. Thermal expansion refractory materials 51, 52, 53, 54 are arranged on the indoor side surface of the installation portions 211c and 221c.

Then, in the event of a fire, the thermal expansion refractory materials 51, 52, 53, 54 expand and fill the spaces S1 and S2, so that the toxic gas generated when the connecting material is burned is surely confined inside the fire prevention door body 1. It is possible to prevent the upper frame 21 and the lower frame 22 from being discharged to the outside, and to prevent the indoor and outdoor communication between the upper frame 21 and the lower frame 22 and the upper stile 31 and the lower stile 32.

On the other hand, as shown in FIGS. Due to the fact that the hanging side of the arm 44 protrudes from the prospective surface of the hanging stile 324 to the outer peripheral side and the influence of the opening / closing trajectory of the shoji 3, a relatively wide interval is required, and therefore the vertical frames 23 and 24 are expected. A large amount of thermal expansion material was required to fill the space between the surface and the door end stile 33 and the hanging base stile 34 with the thermal expansion material. In addition, there is a risk that unevenness will occur due to expansion in a wide space and a gap will be generated.
In particular, in the space on the hanging side where there are no members such as the lock pin 48 and the lock piece 49 on which the thermal expansion refractory material is caught, the expanded refractory material drips between the vertical frame 24 and the hanging base frame 34. There was a possibility that a gap would be created.

Therefore, a protruding piece 345 that projects in the longitudinal direction toward the outer peripheral direction is provided on the outer peripheral side surface of the hanging base stile 34, and the extending portion 241c and the protruding piece 345 of the outer member 241 of the vertical frame 24 are used. A space S3 continuous with the connecting member 243 is partitioned between the hanging base 34 and the vertical frame 24.
A thermal expansion refractory material 56 is arranged on the prospective surface of the vertical frame 24 in the space S3 so as to cover the connecting material 243.

As a result, in the event of a fire, the thermal expansion refractory material 56 expands in the space S3 narrowly partitioned by the extending portion 241c of the outer material 241 and the projecting piece 345, and fills the space S3 and occurs when the connecting material burns. It is possible to confine the toxic gas to the inside of the fire prevention door main body 1 to prevent it from being released to the outside, and to block the communication between the vertical frame 24 and the hanging stile 34.

Further, the protruding piece 345 protruding into the space between the hanging base stile 34 and the vertical frame 24 itself has the effect of hindering communication in the indoor and outdoor directions at a wide distance between the hanging base stile 34 and the vertical frame 24. Further, when the shoji 3 is warped due to the heat of a fire, the shoji 3 is curved into a warp prevention piece 242d provided on the inner peripheral surface of the vertical frame 24 on the hanging side in the inner peripheral direction. The protruding piece 345 of the hanging stile 34 of the above can be brought into contact with the hanging piece 345, and the generation of a gap due to warpage can be suppressed.

As described above, the outer peripheral side surface of the hanging stile 34 is provided with a projecting piece 345 projecting in the longitudinal direction toward the outer peripheral direction, and the projecting piece 345 and the extending portion of the outer material 241 of the vertical frame 24 are extended. A space S3 is formed by partitioning the space S3 between the hanging base 34 and the vertical frame 24 generated when the opening / closing window W is closed by the 241c, and the thermal expansion refractory material 56 is provided in the space S3. The expanded refractory material can be expanded and filled in the small space S3, and the toxic gas generated when the connecting material is burned can be trapped inside the fireproof door body 1 and prevented from being released to the outside. At the same time, it is possible to prevent indoor / outdoor communication between the vertical frame 24 and the hanging stile 34.

Further, since the warp prevention piece 242d is provided on the prospective surface portion 242c of the inner profile member 242 of the vertical frame 24 on the hanging side of the opening / closing window W toward the inner peripheral direction, even if the shoji 3 warps in the event of a fire. The protruding piece 345 protruding into the space between the hanging stile 34 and the vertical frame 24 can come into contact with the warp prevention piece 242d to prevent further warpage, and a gap is generated due to the warp of the shoji 3. Can be prevented.

In the above embodiment, a vertical sliding window provided on the fireproof door is illustrated as an opening / closing window, but the place where the opening / closing window is installed and the method of the opening / closing window are not limited, and the toilet of the building, It can be used for opening and closing windows provided in bathrooms and other rooms, and can be used for any type of window as a technique for sealing the space between the window frame and the shoji with a thermal expansion material.
