るようになっている。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a heat-resistant sheet shutter according to a preferred embodiment of the present invention. 1 and 2 show the structure of the lower part of the sheet. Reference numeral 1 denotes a sheet made of a flexible heat-resistant material, for example, on both sides or one side of a sheet of heat-resistant fiber such as silicon or silicate synthetic fiber, for example, silicone resin or the like. It is coated with a refractory material such as a fluororesin, the lower part of which is inserted from the upper opening 3 of a seat plate (weight) 2 made of a combination of mold steel, the weight member 4 is fixed to the lower end thereof, and 2), the seat plate 2 is suspended, and in a lowered state (see FIG. 1), the floor 5
The seat plate 2 is seated on the seat 1, and the upper opening 3 of the seat plate 2 is closed by the heat shield members 6 (61, 62) sewn to both lower surfaces of the seat 1, so that the space between the seat 1 and the floor surface 5 is shielded. It is supposed to be.

は良好な防災効果が得られる。The above-mentioned heat shielding member 6 (61, 62) is made of the same flexible and heat-resistant material as the sheet 1,
The upper edge portion is stitched integrally with the seat 1 and the lower portion thereof is in a free state. When the seat 1 is wound up, the heat shielding members 61 and 62 are attached to the seat plate 2.
Away from the L-shaped steel 41, 4
The bolts and nuts 8 and 9 for fixing the flat bar 43 and the reinforcing flat bar 43 to the seat 1 are covered by the heat shielding members 61 and 62. As a result, the boundary between the seat plate 2 and the seat 1 is protected, and when the seat 1 is wound up, the seat 1 directly comes into contact with the lintel portion 10 (see FIG. 5) provided immediately below the winding device 31. Therefore, the heat resistance of the portion is prevented from lowering, and the upper opening 3 of the seat plate 2 is prevented.
Is shielded by the heat shielding members 61 and 62, so that a good disaster prevention effect can be obtained in the event of a fire.

The supporting cloth member 22 made of glass cloth is inserted, and the cloth member 22 is sewn together with the folded piece portion 12 that is superposed on the two sheets. With such a configuration, the side edges 11 of the sheet 1 slidably in contact with the guide rails 20 are effectively reinforced, so that a decrease in heat resistance is prevented, and the heat shielding member 6 provided below the sheet 1 is provided.
Together with 1, 62, the passage P can be effectively blocked, and the disaster prevention effect can be further improved. 24 is the sheet 1

Thus, the space Q above the ceiling plate 35 is blocked immediately above the seat 1. Accordingly, in combination with the above-described effect of blocking the passage P by the sheet 1, the movement of fire and smoke is more effectively prevented, and a high disaster prevention effect can be obtained. In addition, manual winding,
In the lowering operation, a handle (not shown) is inserted into a manual winding device attached to a side wall (not shown) so as to interlock with the above-mentioned winding device 31 so that the sheet 1 can be opened and closed from any side. ing.

得ることができる。In the apparatus configured as described above, in the event of a fire or the like, the spread of the fire can be prevented by lowering the seat 1 by electric or manual operation to block the passage P and prevent the movement of the flame or smoke. Although it can be effectively prevented, since the lower portion and the side portions of the sheet 1 are reinforced, good heat resistance can be secured, and the ceiling plate 35 or the like falls on the sheet 1 or foreign matter falls down. Even if it collides with the sheet 1, it is not easily broken, and a high disaster prevention effect can be obtained.
