The flame-retardant fire-resistant sheet body 14, the see-through fire-resistant glass 19 of the fire-resistant see-through part 18
In the refractory edge frame 20, the term "fireproof" means that the frame is resistant to heat of fire and hard 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 guide grooves 3 of the left and right guide rails 1 and lowered.

The grounding surface 17 of the seating body 16 at the lower end of the flame-retardant refractory sheet 14 comes into contact with the floor surface 15 of the shielded portion 2 to be seated, and the operation of the motor 10 is stopped. The shielded portion 2 is completely closed by the flame-retardant fire-resistant sheet member 14, and the front side and the opposite side are partitioned in an airtight state by the flame-retardant fire-resistant sheet member 14, thereby preventing the diffusion of smoke and the spread of fire. .

At this time, the flame-retardant refractory sheet body 14 is
, The plurality of fire-resistant see-through portions 18 are provided in the vicinity, and the fire situation and the like on the opposite side of the flame-retardant fire-resistant sheet member 14 can be easily confirmed from the near side through each fire-resistant see-through portion 18.
Therefore, evacuation, guidance, rescue activities, and the like can be performed quickly and smoothly depending on the fire situation and the like.

Further, since the flame-retardant fire-resistant sheet 14 has flame retardancy and each fire-resistant see-through portion 18 has fire resistance, the flame-retardant fire-resistant sheet 14 and each fire-resistant see-through portion 18 It does not easily burn due to the heat of fire, etc., and can contribute to evacuation, guidance, rescue activities, etc.

Further, since each of the fire-resistant see-through portions 18 has the see-through fire-resistant glass 19, the flame-retardant fire-resistant sheet is passed through the respective see-through fire-resistant glass 19 from the near side when the shielded portion 2 is completely shielded. The fire situation on the opposite side of the body 14 is easily confirmed, but the heat resistance and flame resistance of the see-through fire-resistant glass 19 ensure that the spread of smoke and the spread of fire in combination with the fire-resistant fire-resistant sheet body 14 are ensured. Is prevented.

Incidentally, the flame-retardant refractory sheet 14 may be lowered in the event of a fire to completely close the shielded portion 2.
Further, the flame-retardant refractory sheet 14 may completely cover the shielded portion 2 in normal times other than during a fire.

Further, each of the fire-resistant see-through portions 18, that is, each of the fire-resistant fire-resistant glass 19 is provided on the fire-resistant fire-resistant sheet 14 in the vicinity of the seating body 16, so that the fire-resistant fire-retardant sheet 14 is provided. When the fire-resistant sheet body 14 is rolled up and raised, the fire-resistant fire-resistant sheet body 14 is sufficiently wound on the winding drum 7 without winding the transparent fire-resistant glass 19, and the rolled-up flame-retardant Each transparent fire-resistant glass 19 is raised to a position above the shielded portion 2 without being sandwiched between the fire-resistant sheet members 14, so that the shielded portion 2 is fully opened.

Then, the transparent fire-resistant sheet 19 is not wound between and sandwiched between the fire-resistant fire-resistant sheet members 14, so that the fire-resistant fire-resistant sheet member 14 is wound up orderly, and the height of the screen box 5 is reduced. The size can be reduced.

Next, in the above-described embodiment, the case where each transparent fire-resistant glass 19 sandwiches the edge frame 20 at the peripheral edge and directly exposes both side surfaces of each transparent fire-resistant glass 19 has been described.

The peripheral edge of the transparent fire-resistant glass 19 may be sandwiched by the edge frame 20 together with the peripheral edge of the transparent fire-resistant glass 19.

With this configuration, when the transparent fire-resistant glass 19 is broken, the broken glass pieces with the broken transparent fire-resistant glass 19 are prevented from being scattered by the fire-resistant porous body 25 from both sides. The risk of injury due to stepping on glass fragments during guidance, rescue operations, etc. is prevented.

When a wire mesh is used as each fire-resistant porous body 25, the see-through fire-resistant glass 19 is seen through the mesh of the wire mesh, and the see-through fire-resistant glass 19 is protected from both sides by the entire wire mesh. When the transparent fire-resistant glass 19 is broken, the glass fragments are prevented from being scattered from both sides, and furthermore,
Mounting work is easy and inexpensive.

When a punching metal is used, a transparent fire-resistant glass is formed in each hole of the punching metal.
The transparent fire-resistant glass 19 is protected from both sides by the whole of the punching metal, and when the transparent fire-resistant glass 19 is broken, the hole diameter prevents the glass fragments from being scattered from both sides. Work is easy and inexpensive.

Next, in the above-described embodiment, the case where the plurality of fire-resistant see-through portions 18 are provided on the wind-up type flame-retardant fire-resistant sheet 14 wound around the wind-up drum 7 has been described. As shown in FIG. 5, for example, as shown in FIG. 5, the plurality of fire-resistant see-through portions 18 are wound around a winding drum 7 to pull up the fire-resistant fire-resistant sheet body 14 and fold it. It may be provided on the body 14.
5 shows a state in which the flame-retardant refractory sheet 14 is pulled up and folded, and a chain line in FIG. 5 shows a state in which the flame-retardant sheet 14 is lowered and the shielded part 2 is closed.

Regarding the configuration, reference numerals used in the above embodiment are added, and the description is omitted.

With this configuration, the operation is performed in the same manner as in the above-described embodiment, and the flame-retardant refractory sheet 14
When the shielded part 2 is closed by descending, the side opposite to the front side is partitioned off in an airtight state by the flame-retardant fire-resistant sheet member 14, so that the diffusion of smoke and the spread of fire are prevented. The flame-retardant fire-resistant sheet 14 is located in the vicinity of the seat 16 and has a plurality of fire-resistant see-through portions 18.
With this configuration, it is possible to easily check the fire status and the like on the opposite side of the flame-retardant fire-resistant sheet member 14 from each side through the fire-resistant see-through portions 18. Therefore, evacuation, guidance, rescue activities, and the like can be performed quickly and smoothly depending on the fire situation and the like.

Next, in the above-described embodiment, the case where the fire-resistant see-through portion 18 is made of the see-through fire-resistant glass 19 has been described. However, the present invention is not limited to this. It may be made of a synthetic resin plate. In this case, the present invention is effective for a wind-up type fire-resistant screen device for winding up the flame-retardant fire-resistant sheet 14. That is, when the flame-retardant fire-resistant sheet 14 is wound up, the transparent fire-resistant synthetic resin plate is elastically deformed, and this transparent fire-resistant synthetic resin plate is caught between the flame-retardant fire-resistant sheet members 14. The refractory sheet body 14 is wound up without being bulky.
