Description of the Related Art In general, this type of fire and smoke prevention device for a rolled-up sheet shutter has a bag portion formed in a lateral direction of the sheet shutter, a reinforcing pipe is inserted into the bag portion, and both ends are guided. Had been extended to the rails. In this case, since the strength increases as the width of the sheet shutter increases, it is necessary to increase the diameter of the pipe or increase the number of pipes. Also,
There are drawbacks such as the groove width of the guide rail becoming large and the outer diameter when being wound up on the shaft of the winding cylinder.

However, in this case, there are disadvantages in that it is very difficult to fix the sheet shutter to the metal, and the sheet is easily damaged because the metal is exposed. In addition, various types of smoke shielding materials such as rubber are attached to the inside of the guide rail, but they are not effective in an emergency, and have a drawback that they are easily broken.

分に果たすものである。The seat shutter of the present invention configured as described above serves as a fire and smoke proof by ascending and descending between the left and right guide rails (1). Both ends of the sheet shutter (3) and the swelling press contact portions (9) (9) are constantly pressed against the inside of the guide rails (1) and (1) to shut off ventilation from inside and outside to prevent fire and fire. It plays the role of smoke.
Further, when wind pressure is applied from the front and back surfaces of the sheet shutter (3), the bulging pressure contact portion (9) is pressed against the rail inner surface side to form a plurality of ridges of a two-step bulging portion. Then, they are pressed against each other in a close contact state to reliably prevent leakage and sufficiently fulfill the functions of fire prevention and smoke prevention.

に、捲込胴を小型化できる効果がある。Since the present invention is constructed as described above, there is no fear that the sheet is scratched or damaged as in the case where a tongue piece or a metal piece is mounted in a guide rail as in the prior art. This has the effect of reliably preventing the seat shutter from coming off the guide rail. Then, both ends of the sheet shutter to which the non-combustible sheet pieces are sewn are formed into a bag-shaped wrapped portion, and a short body made of a non-combustible rope or non-combustible cloth is internally provided at a predetermined interval in the wrapped portion. As it is buffered and contacts the inner surface of the guide rail to prevent breakage, it has the effect of completely preventing both ends of the seat shutter from coming off, and the short body is inserted at a predetermined interval. In addition, the diameter of the sheet wound around the winding shaft is reduced, and the size of the winding cylinder can be reduced.

Air leakage can be safely prevented by always in contact with the inside of the sheet, and according to the swelling pressure contact portion, when the sheet shutter is subjected to wind pressure from the front and back, the swelling pressure contact portion is also attached to one side. Since it is inclined and pressed to form a two-step bulging portion, there is an effect that smoke and the like can be reliably prevented from entering.
