DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof screen mounting apparatus, and more particularly, to a fireproof screen mounting apparatus for mounting a fireproof sheet body on a winding shaft for preventing the spread of smoke and the spread of fire in a fire.

[0002]

2. Description of the Related Art Conventionally, as this type of fireproof screen device, for example, a winding shaft is rotatably provided on a ceiling of a shielded portion such as an opening of an entrance, and the shielded portion is shielded by the winding shaft. There is a known configuration in which the upper end of the refractory sheet body to be mounted is attached with a plurality of mounting screws at predetermined intervals in the width direction of the refractory sheet body, and the refractory sheet body is rewound around the winding shaft so as to be freely rewound. Have been.

[0003]

In the above-mentioned conventional configuration,
Since the refractory sheet body is relatively thin and light, there is a problem that the refractory sheet body does not easily fall down when descending, and that the lower end of the refractory sheet body does not easily adhere to the floor surface of the shielded part.

Therefore, it is necessary to quickly drop the fire-resistant sheet body onto the lower end of the fire-resistant sheet body and attach a landing body that also functions as a weight to bring the lower end of the fire-resistant sheet body into close contact with the floor surface of the shielded part. It is considered.

However, in this configuration, when the refractory sheet is rewound and the shielded part is shielded, the upper end of the refractory sheet is pulled by the weight of the flooring body itself, and the upper end of the refractory sheet is closed. There is a problem that the screw mounting portion mounted with the plurality of mounting screws is easily broken, and the upper end of the fireproof sheet body is easily detached from the plurality of mounting screws.

Further, when the fire-resistant sheet is blocked by a strong wind pressure during a fire when the shielded portion is shielded, or when an external force is applied to the fire-resistant sheet during evacuation or the like, the upper end of the fire-resistant sheet is damaged. Is pulled, and the upper end portion of the fire-resistant sheet body is easily detached from the plurality of mounting screws.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the upper end of a flame-retardant refractory sheet can be securely attached to a winding drum. Even if the upper end of the flammable fire-resistant sheet is pulled by an external force or pulled by an external force, the upper end of the flame-retardant fire-resistant sheet can be prevented from coming off the winding drum, and its installation is simple and easy. The purpose is to provide.

In a state where the folded portion 21 is sandwiched between the drum and the drum 7, the retaining protrusion 20 is attached by the mounting bracket 34.
Is stopped and fixed.

When the flame-retardant refractory sheet body 14 is wound, the rotation of the winding drum 7 causes the flame-retardant fire-resistant sheet body 14 to be wound ahead of the retaining ridge 20. Has become. Further, when the flame-retardant refractory sheet 14 is rewound by the winding drum 7 and the shielded part 2 is shielded by the flame-retardant fireproof sheet 14, the floor of the shielded part 2 is closed. The flame-retardant refractory sheet 14 is tensioned by the flame-retardant landing body 16 that has landed on the surface 15 and the attachment 32 that is attached to the winding drum 7.

The flame-retardant refractory sheet 14, the flame-retardant flooring
16. The flame-retardant sewing thread 22, the retaining ridge 20, and the attachments 28 , 32 are resistant to heat of fire and difficult to burn.

Next, the operation of the above embodiment will be described.

In the event of a fire, the motor 10 is operated to
When the winding shaft 8 is rotationally driven in the direction of rewinding the flame-retardant refractory sheet body 14 by the output from the motor, the flame-retardant fire-resistant sheet body 14 is sequentially rewound by the winding drum 7 of the winding shaft 8. While being guided by the insertion openings 3 of the left and right guide rails 1, and is smoothly lowered by the weight of the flame-retardant flooring body 16.

Then, the flame-retardant landing body 16 at the lower end of the flame-retardant refractory sheet 14 is brought into close contact with the floor surface 15 of the shielded portion 2 and the operation of the motor 10 is stopped. The shielded portion 2 is quickly and completely shielded by the fire-resistant sheet 14 and the flame-retardant flooring body 16. Partitioning prevents the spread of smoke and the spread of fire.

At this time, the retaining ridge 20 at the upper end of the flame-retardant refractory sheet 14 is attached to the winding drum 7 by the fixtures 28 and 32. even if such parts is pulled, the retaining projection 20 of the upper portion is supported by the fitting 28, 32, the fixture 28, 32
As a result, the retaining ridge 20 does not fall out of the cover, so that the flame-retardant refractory sheet 14 is kept in a state where the shielded portion 2 is shielded.

The retaining ridge 20 is a flame-retardant fire-resistant sheet.
By folding back the upper end of 14 via a rod-shaped core material 19 and forming the folded portion 21 fixed to the flame-retardant fire-resistant sheet body 14, the retaining ridge 20 has a flame-retardant fire-resistant property.
The retaining ridges 20 are easily formed as fittings 28 and 32.
It is securely supported without slipping out, and its attachment is easy.

One of the attachments 28 is a retaining ridge.
Since the pressing plate 29 is in contact with the turn-up portion 21 and a plurality of mounting screws 30 for attaching the press-down plate 29 to the winding drum 7 through the turn-up portion 21, the When the upper end is pulled, the retaining ridge 20 is held down by the upper end of the flame-retardant refractory sheet body 14 being pressed by the holding plate 29 screwed by the plurality of mounting screws 30. It is possible to prevent the formation of loose wrinkles at the upper end portion of the flame-retardant refractory sheet body 14 as well as to ensure that it does not come off.

[0043] The other fitting 32 includes a plurality of mounting screws 33 for mounting the winding drum 7, of the plurality mounting screws 33
Support plate that is attached to and retains the retaining ridge 20
Since the upper end of the flame-retardant refractory sheet body 14 is pulled, the retaining ridge 20 is supported by the support plate portion 38 of the supporting member 34, In addition to ensuring that the article 20 does not come off, the flame-retardant refractory sheet 14
The formation of loose wrinkles at the upper end of the sheet can be more reliably prevented.

Further, the upper end of the flame-retardant fire-resistant sheet 14 can be formed on the winding drum 7 without the necessity of forming a hole for forming a plurality of mounting screws 33 at the upper end of the fire-resistant fire-resistant sheet 14. Parts can be easily attached. Further, since there is no plurality of mounting holes, the strength of the upper end portion of the flame-retardant refractory sheet body 14 is not weakened, so that it can be used for a long time.

Next, in the above-described embodiment, the weight body is a flame-retardant landing body attached to the lower end of the flame-retardant refractory sheet 14.
Although description has been made by exemplifying the example 16, the weight is not limited to this. For example, the weight may be a reinforcing material that is attached to the flame-retardant refractory sheet 14 in the middle thereof as a reinforcement. That is, the weight body allows the flame-retardant fire-resistant sheet 14 to fall smoothly, thereby shielding the shielded portion 2.
What is necessary is just to be able to bring the lower end of 14 into close contact with the floor surface of the shielded portion 2.
