摘要： PROBLEM TO BE SOLVED: To effectively cut off a flame and smoke while easily securing an evacuating opening part by extending an auxiliary sheet being deformable by a temperature rise at fire time and sandwiching an end part of the other sheet body together with one sheet body along the end part of the other sheet body on one sheet body for forming a superposing part. SOLUTION: At ordinary time, an auxiliary sheet 7 is folded back in the center, and is wound on a winding shaft 1 in a double ply state. While, at fire time, a screen 2 composed of first/second sheet bodies 3, 4 is delivered by receiving a fire signal to close an opening part, and at the beginning, the auxiliary sheet 7 exists in a position separate from a right end part 3a of the first sheet body 3 still in a double ply state. Thus, the first sheet body 3 can be push-opened by hand so that an evacuating opening part S can be easily formed. However, when an ambient temperature rises, a sheet belt 8 expansively opens by restoring force of the auxiliary sheet 7, and an end part of the first sheet body 3 is sandwiched by the auxiliary sheet 7 and the second sheet body 4 to cut off the outflow of a flame and smoke.

摘要： PROBLEM TO BE SOLVED: To easily form an opening for taking shelter at the time of shelter, and also to properly close the opening after the refugees passed through the opening provided to sheets. SOLUTION: A screen 2 for entirely closing an opening part is constituted by two sheet bodies 4, 5 whose end parts in the width direction are mutually overlapped to each other, and a sheet plate 6 is provided to the lower end of the screen 2, and a base plate 9 of a prescribed length extended in the width direction of the opening from the overlapped part is provided to the lower end of the sheet body 5 on one side separately from the sheet plate 6. The base plate 9 is flexible via a plate spring 13 provided to the other end of the base plate in the length direction, and an opening for shelter is formed in the screen 2 by opening at least a part of the sheet body 5 on one side making a door front side of the overlapped part, and the sheet body 5 on one side opened at least a part thereof is returned to its initial position by means of the force of the plate spring 13.

摘要： PROBLEM TO BE SOLVED: To provide a fire shutter allowing a person to escape by oneself even if nipped between a shutter curtain and a floor surface by providing a shutter curtain for opening and closing an opening part consisting of a fireproofing sheet occupying the surface area to a prescribed height in the full close of the opening part and a metallic slut occupying the surface area other than this. SOLUTION: A shutter curtain 3 is regularly wound on a winding shaft and housed in the ceiling above an opening part. When a fire occurs, an automatic closing device is operated according to the fire generation signal from a sensing means, and the shutter curtain 3 is automatically lowered by the weight of a seat plate 40 provided in the lower end while both the lateral end parts are guided by guide rails 5. In this case, the shutter curtain 3 consists of an upper part formed of a steel slat 3a and a lower part formed of a fireproofing sheet 7. The seat plate 40 is arranged on the upper end of the fireproofing sheet 7, and the upper end part is fixed to the steel slat 3a through a laterally extending flat bar 8.

摘要： PURPOSE: To improve a heat insulation property of a shutter curtain by providing a heat insulator on one side of a slat for forming the curtain. CONSTITUTION: A heat insulator B which is so constructed that a thermal insulating cover body 9 covering a thermal insulating material 8 and a thermal insulating material 5 are supported on a support member 6 is disposed on the other side of a slat surface 2a for forming a shutter curtain. The vertical length of the heat insulator B is set to such a length that the end parts of the heat insulator 8 and the fully opened shutter curtain adjacent to each other are closely opposite to each other without being limited by the interlock connecting parts 2b, 2c. The heat insulator B overlops the upper interlock connecting part 2b of the slat 2. Accordingly, the upper and lower interlock connecting parts 2b, 2c are provided in such a closing state as to overlap with the heat insulator B, whereby the regions form heat bridges so as to improve a heat insulation property.
