The right and left guide rails (14) and (14) are used to wind up and down by a winding shaft (16) housed in an upper shutter case (15). The fire prevention shutter (1)
Is provided with a seat plate (2) over the entire lower end. As shown in FIG. 3, a safety storage box (3) is attached to the seat plate (2) over the entire lower surface. The safety storage box (3) has a shaft (5) having a spring built therein. The shaft (5) has about 600 mm made of various woven fabrics such as silica cloth, acrylic resin, and glass cloth.
A non-combustible cloth (6) is wound up and down freely. A decorative board (7) is supported at the lower end of the non-combustible cloth (6) by hanging. A permanent magnet (8) attached to the safety storage box (3) is provided between the safety storage box (3) and the decorative plate (7).
According to (8), the decorative plate (7) is supported in a sucked state. A movable rod (9) that presses and separates the decorative plate (7) downward is laterally attached to the safety storage box (3).
2) It is pivotally connected by the above. As shown in FIG. 4, a protruding end (13) of the movable rod (9) presses a receiving projection (11) provided on the decorative plate (7). Also,
Reference numeral (10) denotes a pressing piece which pushes up and passes the movable rod (9) upward when it is lowered, and the pressing piece (10) is provided at a predetermined position on the guide rail (14) side. Further, the movable rod (9) does not cause any problem in passing because of the escape mechanism when the shutter is raised. Reference numeral (17) indicates a switch, (18) indicates a lintel portion, and (19) indicates a wall surface of a structure.

When the smoke or heat detector detects the smoke or heat, the fire prevention shutter (1) activates the automatic shutter closing device according to the signal from the receiver, opens the switch (17), and lowers the shutter by its own weight. Let it. At this time, when the movable rod (9) of the safety storage box (3) comes into contact with the pressing piece (10) provided on the guide rail (14) side and is pressed, the movable rod (9) is moved.
The receiving projection (11) of the decorative board (7) is pushed by the protruding end (13) of the tip of the decorative board (7), and the decorative board (7) is made permanent magnet (8) (8).
And the spring in the shaft (5) falls by the weight of the decorative board (7), and the non-combustible cloth (6) is suspended by about 600 mm during the descent of the fireproof shutter (1). A barricade of the non-combustible cloth (6) is formed under the shutter (1) in a state of being hooked, thereby preventing a person or the like from passing through and preventing pinching.

When 1) is lowered to the floor, the non-combustible cloth (6) is completely wound and stored, and the decorative plate (7) is moved to the safe storage box (3) by the permanent magnets (8) and (8). Adhesively supported in its original position. In addition, when the fire prevention shutter (1) is wound up, the movable rod (9) comes into contact with the pressing piece (10) of the guide rail again, but because of the escape mechanism, it can easily pass through.

効果がある。Since the present invention is configured as described above, the non-combustible cloth prevents the shutter from passing under the shutter during its closing and descending automatically by its own weight in an emergency. In addition, since the non-combustible cloth drops in an emergency, the smoke-preventing effect can be sufficiently achieved by preventing the movement of the smoke by the non-combustible cloth. Further, since the safety storage box is provided below the seat plate of the shutter, it is easy to provide the safety storage box, and the size is reduced so that there is no obstruction to the operation of the shutter. In addition, the non-combustible fabric is wrapped up by the shaft provided with the spring provided inside the safety storage box, and can be stored safely.
There is an effect that the decorative board is always safely supported by the permanent magnet provided at the lower end. Further, the movable stick provided on the side of the safety storage box has an effect that the decorative plate can be reliably pressed in an emergency.
