The distal ends of the insertion protruding pieces 32 at both ends protrude on the same plane continuous with the distal ends of the insertion portions 18 of the left and right flame-retardant fire-resistant strips 16.

The support plate 31 is positioned opposite to the respective magnets 27 at the lower ends of the plurality of flame-retardant refractory sheets 15 and is provided with the respective magnets 27 of the plurality of flame-retardant refractory sheets 15. The magnetic bodies 33 to be adsorbed are buried integrally. Each of the magnetic bodies 33 is formed in a long shape in a thin narrow plate shape.

The lower ends of the flame-retardant fire-resistant strips 16 on both sides are integrally attached to both ends of the support plate portion 31, respectively. Thus, the support plate portion 31 has a pair of opposed holding plates 34, and the left and right flame-retardant fire-resistant strips 16 each have a retaining ridge 35 at the lower end.
The left and right flame retardancy is provided between the pair of holding plates 34 in a state in which a retaining ridge 35 at the lower end of the left and right flame-retardant refractory strip 16 is projected below the pair of holding plates 34. Refractory strip 16

And the magnetic body 24 adsorbed by the magnet body 25 is closed in an overlapped state, and therefore, the flame-retardant refractory sheet body
14 is wound around the winding drum 8 in a state where the overlap margins 17 and 19 are always separably closed.

The mutually opposing surfaces of the lower end of each of the plurality of flame-retardant fire-resistant sheets 15 of the flame-retardant fire-resistant sheet 14 and the support plate 31 of the flame-retardant flooring body 29 are in contact with the magnet 27. It is closed in a state of being superposed by the magnetic body 33 adsorbed by the magnet body 27,
Therefore, the lower end portions of the plurality of fire-retardant fire-resistant sheets 15 of the fire-retardant fire-resistant sheet body 14 are always supported so as to be separably closed to the fire-retardant flooring body 29.

The plurality of flame-retardant refractory sheets 15 and the flame-retardant flooring body 29 of the flame-retardant refractory sheet body 14 are meant to be highly resistant to the heat of a fire or hot air at the time of a fire and to be difficult to burn.

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

When the motor 10 is operated by a fire signal from the control means in the event of a fire that shields the shielded portion 2, the output from the motor 10 causes the winding shaft 8 to rotate the flame-retardant fire-resistant sheet 14.
The flame-retardant refractory sheet body 14 is guided by the left and right guide rails 1 while being rewound sequentially by the winding drum 7 of the winding shaft 8, and is lowered.

At this time, the insertion portions 18 of the flame-retardant refractory strip 16 at both ends and the insertion projections 32 at both ends of the flame-retardant landing body 29 are inserted into the insertion openings 3 of the left and right guide rails 1 respectively. In this state, it is lowered along the left and right insertion ports 3,
The flame-retardant refractory sheet 14 and the flame-retardant floor 29 are lowered smoothly and quickly.

Then, the lower end surface of the flooring member 30 of the flame-retardant flooring body 29 at the lower end of the flame-retardant refractory sheet body 14 is landed on the floor surface 28 of the shielded part 2 and the control means is activated. The operation of the motor 10 is stopped by this control means, and the landing member 30
The shielded portion 2 is securely shielded by the flame-retardant fire-resistant sheet member 14 and the flame-retardant flooring member 29 in a state where the lower end surface is in close contact with the floor surface 28 of the shielded portion 2.

At this time, the mutually facing surfaces of the adjacent overlap margins 17 of the respective flame-retardant refractory sheets 15 of the flame-retardant refractory sheet body 14 are overlapped by the magnet body 25 and the magnetic body 24 without gaps. The mutually facing surfaces of the overlap margin 19 of the outer end of the flame-retardant refractory sheet 15 on both sides and the inner end of the flame-retardant refractory strip 16 at both ends are closed with the magnet body 25 and the magnetic body 24, respectively. Further, the mutually opposing surfaces of the lower end portion of each flame-retardant refractory sheet 15 and the support plate portion 31 of the flame-retardant flooring body 29 are magnetized and magnetic bodies 33 and 33, respectively. As a result, the shielded portion 2 is completely shielded by the flame-retardant fire-resistant sheet 14 having a flame-retardant flooring body 29 at the lower end.

Even if the fire-retardant fire-resistant sheet 14 is blown by wind pressure or the like in a fire, or if a pressure difference is generated between the near side and the opposite side of the fire-resistant fire-resistant sheet 14, Between the overlapping margins 17 of the respective flame-retardant refractory sheets 15 and between the overlapping margins 17 of the flame-retardant refractory sheets 15 on both side ends and the flame-retardant refractory strips 16 at both ends, and between the respective margins. The gap between the lower end of the fire-resistant fire-resistant sheet 15 and the support member 31 of the flame-retardant flooring body 29 can be easily opened and does not become a smoke outlet, and the airtightness between these members is maintained. .

Therefore, the spread and spread of smoke from the shielded part 2 in the event of a fire can be prevented by the flame-retardant refractory sheet 14 having the flame-retardant landing body 29, so that evacuation, guidance, rescue activities, etc. can be performed quickly. It will be possible to carry out the activities smoothly and contribute to these activities.

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

Next, in the case of an emergency where evacuation, guidance, rescue activities, etc. are performed from the shielded portion 2 when the shielded portion 2 with the flame-retardant refractory sheet body 14 unwound is shielded, for example, When performing evacuation, guidance, rescue activities, etc. from the near side to the opposite side, push the flame-resistant fire-resistant sheet 15a at one end of the fire-resistant fire-resistant sheet body 14 from the near side to the opposite side. Then, the one fire-resistant fire-resistant sheet 15a is pushed open from the near side to the opposite side, and one end of the shielded portion 2 is opened as an emergency exit 21 with the fire-resistant fire-resistant sheet 15a.

That is, the flame-retardant refractory sheet 15 at one end
a from the near side to the opposite side, the magnet body of the overlap margin 17 on the inner end of this one flame-retardant refractory sheet 15a
25 is the overlap margin of the outer edge of the adjacent flame-retardant fire-resistant sheet 15b.
In addition to being easily separated from the magnetic material 24 of the flame-retardant fire-resistant sheet 15a, the magnet body 25 of the overlap margin 17 on the outer end of the fire-resistant fire-resistant sheet 15a is easily separated from the magnetic material 24 of the fire-resistant fire-resistant strip 16 at one end. The magnet body 27 at the lower end of the one flame-retardant refractory sheet 15a is easily separated from the magnetic body 33 of the support plate part 31 of the flame-retardant landing body 29.

Therefore, the flame-retardant fire-resistant sheet at one end
The Rukoto is pushed toward the opposite side 15a from the front side, the one flame retardant refractory sheet 15a is pushed open from the front side toward the opposite side, the hidden in this flame retardant refractory sheet 15a One end of the part 2 is easily opened as an emergency exit 21 and can easily pass through the emergency exit 21 to perform evacuation, guidance, rescue activities, and the like.

At this time, the flame-retardant refractory sheet 15a at one end
Emergency exit indication 20 is formed on the surface (front side) of the vehicle, so that emergency exit 21 is appropriately indicated in emergency exit indication 20 in the event of emergency such as evacuation, guidance, rescue, etc. It can be fully contributed to evacuation, guidance, rescue activities, etc. In addition, since the intrusion prohibition sign 22 is formed on the surface (front side) of the other fire-resistant fire-resistant sheet 15b adjacent to the one fire-resistant fire-resistant sheet 15a, the other fire-resistant fire-resistant sheet 15b is erroneously made in the event of a fire emergency. Flammable fireproof sheet
This can sufficiently contribute to the prevention of the action of pushing the 15b from the near side to the opposite side or forcing the flame-retardant refractory sheet 15b to open.

The fire-retardant refractory sheet 15a at one end is pushed open to open the emergency exit 21. The lower end of the fire-retardant fire-resistant sheet 15a is supported by the support plate of the fire-retardant flooring body 29. Even if it is separated from the part 31, since both ends of the flame-retardant landing body 29 are supported by the left and right flame-retardant fire-resistant strips 16, the insertion portions of the left and right flame-retardant fire-resistant strips 16 are provided. The insertion protrusions 32 at both ends of the fire-retardant flooring body 18 and the flame-retardant landing body 29
There is no departure from.

Next, a flame-retardant refractory sheet 15a at one end is provided.
After passing through the emergency exit 23 which is opened at, the fire-resistant fire-resistant sheet 15a at one end of the pushed-out portion is connected to the adjacent fire-resistant fire-resistant sheet 15b and the fire-resistant fire-resistant strip 16 at one end.

The magnetic body 24 of the overlap margin 17 at the outer end of the adjacent flame-retardant refractory sheet 15b is attracted by the magnet body 25 of the overlap margin 17 at the inner end of the inner end 15a, and the flame retardancy of this one end is Fireproof sheet 15
The magnetic body 24 of the flame-retardant refractory strip 16 at one end is attracted by the magnet body 25 of the overlap margin 17 at the outer end of the a, and the lower end of the flame-retardant fire-resistant sheet 15a at one end. The magnetic body 33 of the flame-retardant landing body 29 is attracted by the magnet body 27.

Therefore, the flame-retardant refractory sheet at one end
After passing through the emergency exit 23 opened at 15a, the emergency exit 21 is automatically closed airtight again by the fire-resistant fire-resistant sheet 15a at one end, and the flame-retardant The shielded portion 2 is shielded by the flame-retardant fire-resistant sheet 14 having the fire-resistant sheet 15a, and the diffusion of smoke from the shielded portion 2 and the spread of fire are prevented.

Next, when another fire-resistant fire-resistant sheet 15b adjacent to one fire-resistant fire-resistant sheet 15a is used as the emergency exit 23, the other fire-resistant fire-resistant sheet 15b is moved from the opposite side to the near side. By pushing inward, the fire-retardant fire-resistant sheet 15b is pushed open similarly to the case where the fire-resistant fire-resistant sheet 15a is pushed open as an emergency exit 21 and is easily opened as an emergency exit 23. Evacuation, guidance, and rescue activities.

After passing through the emergency exit 23 opened by the flame-retardant fire-resistant sheet 15b, the emergency exit 23 is automatically closed by the fire-resistant fire-resistant sheet 15b as in the case of the fire-resistant fire-resistant sheet 15a. It is closed airtight again, and the shielded portion 2 is shielded by the flame-retardant refractory sheet body 14 having the flame-retardant refractory sheet 15b, so that the diffusion of smoke from the shielded portion 2 and the spread of fire are prevented. You.

At this time, since an emergency exit sign (not shown) is formed on the back surface (opposite side) of the fire-resistant fire-resistant sheet 15b, emergency such as evacuation, guidance, rescue operation, etc., Sometimes the emergency exit 23 is appropriately indicated on the emergency exit display and guided without panic, which can sufficiently contribute to evacuation, guidance, rescue activities and the like. In addition, since an intrusion prohibition sign (not shown) is formed on the back surface (opposite side) of the fire-resistant fire-resistant sheet 15a adjacent to the fire-resistant fire-resistant sheet 15b, the fire-resistant fire-resistant sheet 15a is erroneously made in the event of a fire. Fireproof sheet 15a
Can be sufficiently prevented from being pushed from the opposite side toward the front side or the behavior of forcibly pushing open the flame-retardant refractory sheet 15a.

Further, even if the fire-resistant fire-resistant sheet 15b is pushed open to open the emergency exit 23, the lower end of the fire-resistant fire-resistant sheet 15b is separated from the support plate 31 of the fire-retardant flooring body 29. ,
Both ends of the flame-retardant landing material 29 are left and right flame-retardant refractory strips.
Since the supporting portions 16 support the insertion portions 18 of the left and right flame-retardant refractory strips 16 and the insertion protrusions at both ends of the flame-retardant landing body 29.
32 does not come off the insertion openings 3 of the left and right guide rails 1.

Next, in the above-described embodiment, the case where the flame-retardant landing body 29 is formed as one integral body having a common length at the lower end of the flame-retardant refractory sheet 14 has been described. However, the present invention is not limited thereto, and the flame-retardant landing body 29 may be composed of a plurality of divided landing bodies 36.

In this case, each divided landing body 36 is, for example,
As shown in FIGS. 5 and 6, each flame-retardant fire-resistant sheet 15 is formed flat in the same length as the width of the lower end, and the lower end of each flame-retardant fire-resistant sheet 15 is retained at the upper end. The upper end of the ridge 35 is clamped and fixed. Also, each split landing body
A disc-shaped magnetic body 37 is buried in one of opposing surfaces of both ends of 36, and a disc-shaped magnet body 38 for adsorbing the magnetic body 37 is buried in the other side of the opposing surface.

With this configuration, the both ends of each divided landing body 36 are always closed without any gap in a state where the opposing surfaces are superimposed by the respective magnet bodies 38 and magnetic bodies 37. A flame-retardant landing body 29 that is in close contact with the floor surface 28 of the shielded part 2 is configured by the landing body 36.
