2. 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.

Further, in the conventional apparatus, L-shaped or T-shaped hardware is attached to both ends of the sheet shutter to prevent the hardware from being caught in the guide rail groove and coming out to the outside. 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.

Since the present invention is constructed as described above, the sheet may be damaged 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. 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.

In addition, one or more bulging pressure contact portions bulging outward are protrudingly provided on one or both of the end portions of the sheet shutter and the folded short piece having the winding portion extended, so that the guide rail is provided. 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.
