  • Operating, Guiding And Securing Of Roll- Type Closing Members (AREA)

Abstract

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.

2. Description of the Related Art A fire protection shutter which is required to be installed in a building such as a building is provided with a detection means such as a smoke detector and a heat detector and an automatic closing device. The shutter is automatically closed to prevent the spread of hot air flow and smoke due to the fire to prevent the spread of fire. Since the shutter curtain of the fireproof shutter is required to have fire resistance, the shutter curtain of the fireproof shutter is generally formed of a metal slat such as steel.

That is, when the opening is fully closed, at least the main surface area of the surface area from the lower end of the shutter curtain to a predetermined height is formed of a flexible fire-resistant sheet, so that it can be lowered. Even when the fireproof sheet is caught below the shutter curtain, the fireproof sheet functions as a cushion and can be escaped by lifting the fireproof sheet. The refractory sheet does not necessarily need to be provided over the entire width of the shutter curtain, and may be provided so as to occupy most of the width direction. It is preferable to form a refractory sheet having flexibility.

[0007] The fire-resistant sheet may have good fire-resistance performance and flexibility, and is formed of, for example, cloth (silica cloth), a thin metal plate, or a metal foil. A seat plate is provided at the lowermost end of the shutter curtain to promote the lowering of the weight of the shutter curtain, but instead of a single steel seat plate, a chain seat plate or a sandbag is used. By using a flexible seat plate such as a seat plate, escape can be further facilitated.

In the first embodiment, when the opening is fully closed, the refractory sheet 7 occupies most of the height of the opening, and the shutter curtain 30 is suspended. In this state, the refractory sheet 7 serves as a cushion. Therefore, the entire shutter curtain, including the seat plate 40, is lighter in weight than a conventional fireproof shutter made of steel slats, and in the unlikely event that a person is pinched below the shutter curtain. Can escape on their own.

The thing shown in FIG. 4 is greatly different from the first embodiment in that the existing shutter curtain 3 is used as it is simply by removing the seat plate 4. The second guide rail member 50 has a predetermined height H from the lower end of the opening.
(For example, 1 m), and its basic configuration is the same as that of the first embodiment. The width detail 50a formed in the existing guide rail 5 by the second guide rail member 50 has a dimension smaller than the thickness of the steel slat 3a. The refractory sheet 7 has a predetermined height H.

Therefore, when the shutter curtain 3 descends under its own weight, the lower end of the steel slat 3a is moved to the second guide rail.
By contacting the upper edge of the sealing member 50, it does not descend below it, while the fireproof seal provided with the seat plate 40 is provided.
The guide 7 descends to the floor while being guided by the groove formed by the second guide rail member 50. The load caused by the steel slats 3a at the time of its own weight drop is the second guide rail member 50.
Therefore, even if a person falls under the shutter curtain where the person descends, only the burden of the weight of the seat plate is sufficient, and the person can escape by himself. Seat plate 40
Is made of a metal chain or a sandbag, the weight of the entire seat plate does not act on the sandwiched human body.

FIG. 5 relates to a third embodiment of the present invention.
The repair work includes the steps of removing the seat plate 4 of the shutter curtain 3 made of the existing steel slats 3a,
A portion having a predetermined height from the lower end of the curtain 3 is cut and removed while leaving both ends in the width direction of a predetermined width, and the remaining end slat portion 10 is formed.
To fix the cut slats by attaching the end fittings 11 to the slats, and to fasten the refractory sheet 7 to the site where the steel slats have been cut and removed (the refractory sheet 7 is located immediately above the cut portion). And a flexible seat plate 40 such as a chain or a sandbag is fastened to the refractory sheet 7 and the slat portion 10 at the end.

In this case, when the opening is fully closed, the slat weight is supported by the remaining slat portion 10 at the end. Even if it is sandwiched below,
The weight of the entire shutter curtain is not added, and the user can escape by himself. In the second embodiment and the third embodiment, the shutter in the fully closed state is not used.
Most parts are made of steel slats except for a part at a predetermined height from the lower end of the curtain, so it is possible to cope with a case where an object falls down at the time of fire in terms of strength. .

FIG. 6 relates to a fourth embodiment of the present invention.
The repair work is a step (a) in which the slats 3a are welded or screwed together to form the shaft-shaped wrapped body 20 (thick shaft state) in a state where the slats 3a are accommodated in the ceiling above the opening of the building. Step (b) of removing and attaching the refractory sheet 7 provided with the seat plate 40, the second guide rail
The step (c) of repairing the groove width of the existing guide rail 5 to a narrow width so as to correspond to the refractory sheet 7 by providing the rail member 50 is included.

According to the present invention, the shutter curtain housed above the opening of the building is lowered while being guided by the guide rails erected on both right and left sides of the opening, and the opening is completely closed. A fireproof shutter and a shutter which occupy at least a main surface area of a surface area from the lower end of the shutter curtain to a predetermined height when the opening is fully closed. Since it is characterized by comprising a metal slat occupying an area other than the refractory sheet of the curtain, it has good fire prevention (smoke prevention) performance, but has a human descending shutter. Even if it is caught under the curtain, it can escape on its own. Since the shutter curtain according to the present invention can be installed without breaking the existing ceiling, guide rails, etc., it can be advantageously used when renovating a conventional fireproof shutter made of steel slats. It is expected to be adopted.
