Field of the Invention The present invention relates to a rolled-up or lowered fire-resistant sheet shutter, in which the lower end seat plate and the upper end lintel are closed when the lower end and floor are closed. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat plate portion of a roll-up sheet shutter and a lintel fire and smoke prevention device for reliably blocking smoke and the like that pass through a gap between a surface and a lintel portion. 2. Description of the Related Art Conventionally, this type of rolled sheet shutter has a fire and smoke prevention device which is lighter in weight than a metal shutter, for example, and is provided with a shock absorber or the like on the lower surface of a seat plate. There is no need to perform the operation, and the whole is lightweight and the seat plate portion and the floor surface are directly in contact with each other without any intervening material at the lower end of the seat plate portion. In this case, there is a gap between the lower end of the seat plate and the floor, and there is a drawback that in the event of a fire, smoke enters through the gap. Further, as a device for blocking the invasion of smoke and the like from a gap formed in the lintel at the top of the sheet shutter, a conventional metal pipe or the like is used, but metal has a resilient force. Poor adhesion, so it surely blocks smoke and fire,
It is impossible to serve as a smoke proof. SUMMARY OF THE INVENTION [0004] The present invention solves the drawbacks of the above-described conventional seat and lintel fire and smoke prevention devices of a rolled sheet shutter, and has a main object thereof. When the holding plate of the seat plate provided at the lower end of the seat shutter is joined to the floor, the extension of the lower end of the seat shutter is bent and pressed against the floor to block the air flow. In addition, when the upper end of the sheet shutter is closed at the lintel portion, the sheet is filled with a non-combustible rope or the like made of a soft non-combustible rope filled inside the sheet to prevent the invasion and movement of smoke and the like. It is. [0005] In order to achieve the above-mentioned object, in the seat plate portion and lintel fire and smoke prevention device of the rolled-up sheet shutter according to the present invention, the sheet shutter has several sheets. A seat plate portion is formed at the lower end of the sheet shutter formed by sewing non-combustible sheet pieces with opposing holding plates and backing plates. An inclined piece is formed on the holding plate with the lower end directed downward, and a slight gap is formed inside the lower surface of the inclined piece. The lower end of the sheet shutter is extended in the gap to form a bent press contact portion. In addition, a soft noncombustible filling strip is inserted in the upper part of the sheet shutter in the lateral direction so as to be pressed against the inclined support provided in the lintel portion. Referring to the drawings, an embodiment of the present invention will be described. Referring to FIGS. 1 and 2, a sheet shutter (3) for fire and smoke prevention is provided with left and right guide rails (2) and (2). ), It is wound up and down by a winding shaft (18) of an upper winding case (1). The sheet shutter (3) includes:
Several sheet pieces in the vertical direction are continuously formed by sewing portions (17) and (17). The sheet shutter (3)
Is made of a non-combustible woven fabric in which a flame retardant is impregnated into a woven fabric of glass cloth, silica cloth, polyester, acrylic resin or the like. As shown in FIGS. 3 and 4,
The lower end of the sheet shutter (3) is composed of a pair of holding plates (6) and (6) opposed to each other and a pair of contact plates (7) and (7) on the outside thereof, and a bolt (8) and a nut (9). To form a seat plate (5). The holding plates (6) and (6) are formed with inclined pieces (11) and (11) whose lower ends are inclined downward. Slight gaps (12) (12) are formed in the lower surfaces of the inclined pieces (11) and (11). In the gaps (12), (12), a bending press-contacting portion is formed so as to extend and protrude from the lower end of the sheet shutter (3) and be freely bent. In the embodiment shown in FIG. 5 and FIG. 6, inclined support portions (14) (14) which are inclined outward are provided above the lintel portion (20) inside the winding case (1). Form. Sewing portions (17) (17) are provided on the upper side of the seat shutter (3) which does not pass through the inclined support portions (14) (14).
And a filling strip (13) made of a noncombustible rope or a noncombustible soft noncombustible cloth is inserted into the inside of the bag. The portion of the filling strip (13) presses and adheres to the inclined support portions (14) and (14) when closed to prevent air leakage from the lintel portion (20).
Reference numeral (15) indicates a ceiling, (16) indicates a floor surface,
(19) shows a switchgear. The seat and lintel fire and smoke prevention devices of the seat shutter having the above-described structure are adapted to raise and lower the left and right guide rails (2) and (2) to perform the function of fire and smoke prevention. To fulfill. When the seat shutter (3) is closed, before the inclined pieces (11) and (11) come into contact with the floor surface (16), the bent protruding piece (1) at the lower end of the sheet shutter (3).
0) comes in contact with the floor surface (16) first, and the inclined piece (11)
When (11) stops on the floor surface, the bent protruding piece (10) is bent as shown in FIG. Can be prevented. [0010] When the seat shutter (3) is closed, a soft filler filled into the inside of the seat shutter (3) is filled in the opposite inclined support part (14) provided above the lintel part (20). The strips (13) are in close contact with each other by pressure, and air leakage and smoke leakage from the upper portion of the sheet shutter (3) can be reliably prevented. The seat and lintel fire and smoke prevention devices of the seat shutter according to the present invention having the above-described structure completely eliminate the gap between the seat shutter and the floor when the seat shutter is closed. In addition, the effect of preventing the gap in the lintel section to reliably block the ventilation of smoke and the like, and preventing the inflow of smoke entering through the gap in the floor surface as in the past, ensuring the safety of the victims effective. Further, there is an effect that a seat plate portion in which the lower end of the seat is firmly held by the holding plate and the contact plate provided at the lower end of the seat shutter is provided. Since the holding plate is formed as an inclined piece whose lower end is inclined downward, each tip of the opposing inclined piece is in contact with the floor surface, and has an effect of increasing the air leakage effect. With the gap formed inside the lower surface of each inclined piece, the extended bent piece of the sheet shutter is stored and
There is an effect that the bent protruding piece is bent down on the ground contact surface to completely prevent the gap, thereby ensuring the smoke shielding. In addition, the non-combustible filling strip made of a soft material in the lateral direction provided on the upper portion of the sheet shutter is securely joined to the opposite inclined support provided in the winding case when descending, and the soft property is improved. In this way, the non-combustible filled strip is elastically pressed and hermetically sealed, thereby significantly improving the purpose of smoke prevention.
