In the structure described in the above-mentioned publication, the unwound flame retardant sheet is extended by the weight of the divided weight bar. Because of the multiple slits, smoke and the like can easily flow out of each slit in the event of a fire, and when fanned by the wind pressure at the time of fire, each slit opens greatly due to the wind pressure, and the opening of each slit is exhausted. Smoke makes it easier for smoke to flow out, and the divided weight bar extends the unwound flame-retardant sheet. There is a problem that smoke or the like at the time of a fire easily flows out of a gap between the surface and the surface, and therefore, the shielded portion is insufficiently shielded to prevent the diffusion and spread of the smoke.

According to the invention of claim 6, according to claims 1 to 4,
In addition to the effects of the invention, the flame-retardant fire-resistant sheet body has at least two flame-retardant fire-resistant strips on both sides which are arranged in such a manner that the overlap margins of the outer ends of at least two flame-retardant sheets are overlapped. And
The upper ends of the flame-retardant strips on both sides were fixed to the winding drum, and the flame-retardant landing bodies were attached to the lower ends of the flame-retardant strips on both sides. Because the fire-retardant strip supports the flame-retardant flooring,
When the overlap of the flame-retardant refractory sheets is joined to each other by a magnet body so that they can be separated from each other, and the opposing surfaces of the divided landing bodies are adsorbed by the magnet body, one flame-retardant fire-resistant sheet By pushing the sheet from the near side to the opposite side, for example, the overlapping margins can be easily separated from each other, and the divided landing bodies can be easily separated from each other.
