For reference, in order to increase the discriminating power of each component in the drawings, the opening preventing opening 600 is shown only in FIGS. 6 and 7 for convenience, and the opening preventing opening 600 is omitted in FIGS. 1 to 5.

1 to 3, the fire prevention screen shutter having the opening preventing device according to the embodiment of the present invention is wound on the gun holder 200 installed on the ceiling (not shown) and automatically in case of fire. The descending main screen 100 is configured to include.

In this case, a winding roller (not shown) is installed in the winding part 200, and the main screen 100 is raised or lowered while being wound or unrolled by the rotation of the roller.

The upper support 410 is coupled to the upper side 410 in the width direction, that is, the horizontal direction, and the lower support 450 is coupled to the upper side of the main screen 100 in the width direction, that is, the horizontal direction.

Here, the upper support 410 and the lower support 450 is preferably a metal material having a proper weight and heat resistance in order to keep the surface taut by pulling the main screen 100 downward.

Particularly, a fixing member 610 having a locking groove 611 is coupled to one side of the center portion of the lower support 450, so that the third emergency door 570, which is the outermost emergency door, is closed once, the opening room. As the fitting member 620, which is one of the components of the earth 600, is caught by the catching groove 6 11, it is not easily opened even if a fire pressure is formed during a fire, while the evacuator is artificially The technical feature of the present invention is that it can be easily opened and secured.

And, the emergency exit 300 is formed through the main screen 100 between the upper support 410 and the lower support 450, it can pass through it when a fire occurs to evacuate to a safe place.

In addition, as shown, the emergency exit 300, the first emergency door 510, the second emergency door 550 and the third emergency door 570 is installed in a zigzag form.

At this time, the first emergency door 510 has a lower end coupled to the first support member 512 coupled to one side of the lower support 450 as the first hinge 514, and thus an opening is covered while a part of the emergency exit 300 is covered.

A part of the second emergency door 550 is provided to overlap, and in particular, a fitting member 620 that can be caught by the locking groove 611 is coupled to a central portion of the third supporting member 572 at the bottom.

Therefore, even if a fire pressure is formed during a fire, the third emergency door 570 is not easily opened, while the evacuator H is artificially opened easily (FIGS. 6 and 7). Reference)

As configured as described above, the first emergency door 510, the second emergency door 550, and the third emergency door 570 are the other one of the right side or the left side of the emergency exit 300 which is not coupled. That is, the openings are formed by reinforcing bars 515, 555, 575, respectively, and the openings of the emergency exit 300 are entirely covered, so that each of the emergency doors 510, 550, 570 and the main screen 100, and between each emergency door 510, 550, 570. Since smoke, toxic gases and flames do not leak, there is another technical feature of the present invention because the damage caused by the fire is no longer spread to other places.

As a result, the width of the first emergency door 510 is the shortest, the width of the second emergency door 550 is second, and the width of the third emergency door 570 is the widest.

Here, the main screen 100, the first emergency door 510, the second emergency door 550 and the third emergency door 570 is preferably formed of a flame retardant fabric, each of which is a flexible material (flexible) By being made, it can be easily wound or unwound on the winding roller disposed in the winding part 200, and there is another technical feature of the present invention for easy installation and maintenance of the fire screen shutter.

In addition, one end of the first wire 511 is connected to the upper one side of the first emergency door 510, and the other end of the first wire 511 is connected to the upper support 410, and the second emergency door 550. One end of the second wire 551 is connected, the other end of the second wire 551 is connected to the upper support 410, and similarly, the upper one side of the third emergency door 570 is the third wire ( One end of the 571 is connected, and the other end of the third wire 571 is connected to the upper support 410.

At this time, the upper support 410 is provided with an elastic means (not shown), such as a tension spring that can pull the first wire 511, the second wire 551 and the third wire 571, respectively. As a result, not only the emergency doors 510, 550, 570 can be easily opened and closed, but also the main doors 100 are in close contact with the emergency doors 510, 550, 570, and are closed to the winding rollers disposed in the winding part 200. Can be coiled or loosened.

That is, when the first emergency door 510 is opened, the elastic means provided on the upper support 410 pulls the first wire 511 so that the first emergency door 510 opened soon closes automatically. When the second emergency door 550 and the third emergency door 570 are also opened, the elastic means provided in the upper support 410 attracts the second wire 551 and the third wire 571, Soon each closes automatically.

In addition, since the first emergency door 510 is located at the first, the innermost, the second emergency door 550 is located at the second, the next, and the third emergency door 570 is located at the third, The doors 510, the second emergency door 550, and the third emergency door 570 are sequentially opened in the same direction, and are sequentially closed and closed.

Therefore, since the order in which the emergency doors are closed is closed immediately after being first opened, the emergency doors 510, 550, and 570 do not interfere with each other. (See FIGS. 1, 4, and 5).

In addition, each of the first emergency door 510 and the third emergency door 570 has a lower width than the upper width, and the second emergency door 550 has a wider upper width than the lower width. 1, 4 and 5)

In addition, by supporting members 512, 552, 572, such as heavy metal pipes, coupled to the lower ends of the emergency doors 510, 550, 570, the emergency doors 510, 550, 570 are pulled downward and are kept taut.

Here, when the emergency doors 510, 550 and 570 are opened by pushing, only the surface of the force portion of the center portion, which is formed of a plate type, gently protrudes, and the surface is slightly deformed, and the first to be inclined from the top to the bottom, respectively. The emergency door 510, the second emergency door 550, and the third emergency door 570 open and close as a general emergency door.

At this time, each of the emergency door (510, 550, 570) is rotated around the hinge in the process of opening and closing, the closing time is different depending on the difference in the rotation radius, respectively, the closing time of the narrowest first emergency door (510) is the most Fast, followed by the closing time of the second emergency door 550 second, and the closing time of the widest third emergency door 570 is the slowest.

Thus, the order in which the emergency doors 510, 550, 570 are opened and then closed, respectively, is that the first emergency door 510 with the earliest opening time is closed first, the second emergency door 550 is next, and the third emergency door 570 is closed. ) Closes last.

In this case, the first wire 511, the second wire 551, and the third wire 571 may use a steel wire having excellent heat resistance and strength.

As shown in FIG. 4, the lower end of the first emergency door 510 is coupled to the first support member 512 coupled through the lower support 450 and the first hinge 514, and the second emergency door 550. The lower end of the) is coupled to the second support member 552 coupled through the lower support 450 and the second hinge 554, the lower end of the third emergency door 570 is the lower support 450 and the third hinge It is coupled to the third support member 572 coupled through 574.

In addition, since the first hinge 514, the second hinge 554 and the third hinge 574 are provided with elastic means (S) such as a coil spring therein, the emergency doors (510, 550, 570) are respectively the main screen ( 100 to be pressed in close contact with each other, the emergency door (510, 550, 570) is prevented from being easily opened by the fire pressure (fire) in the event of a fire, and at the same time to return immediately after the emergency door (510, 5500, 570), respectively. (See Figure 7)

In addition, when the third hinge 574 presses the third emergency door 570, the third emergency door 570 and the second hinge 554 press the second emergency door 550, and the second emergency door 550 is pressed. The door 550 and the first hinge 514 pressurize the first emergency door 510, thereby eliminating gaps between the emergency doors 510, 550, 570 and the main screen 10 0. Prevent your back from leaking.

Accordingly, the first emergency door 510, the second emergency door 550, and the third emergency door 570 may include the first wire 5 11, the first hinge 514, the second wire 551, and the second emergency door 510. The hinge 554, the third wire 571, and the third hinge 574 are normally kept in the emergency exit 300. (See Fig. 4).

If a fire occurs in a building in which a fire screen shutter is installed, a heat detector (not shown) attached to the ceiling detects this, and emergency power is supplied according to a detection signal. As you descend, you will block the spread of fire.

Subsequently, the emergency doors 510, 550, 570 are pulled in the closing direction by the wires 511, 551, 571, and pressed in the closing direction by the hinges 514, 554, 574, thereby closing and maintaining the state in which the emergency doors 3 00 are closely arranged. .

Since each of the emergency doors (510, 550, 570) closed as described above is arranged in close contact with the zigzag form, it can maintain excellent airtightness, thereby fundamentally blocking the leakage and diffusion of toxic gases, soot, flames, etc., out of the fire zone. There is a technical feature of the present invention.

In particular, even if a fire pressure is generated at the fire site due to the fire, not only the elastic force of each hinge 514,554,574 pressurizing the emergency doors 51 0, 550, 570, but also a fitting member which is one of the components of the opening preventing device 600. As the 620 is locked to the locking groove 611, the emergency doors 510, 550, and 570 may be prevented from being opened.

At this time, in the state where the emergency doors (510, 550, 570) are closed, first, when the evacuator pushes and opens the first emergency door 510 in the exit direction, that is, evacuation direction, the second emergency door 550 is pushed open, and finally, the third emergency door. The emergency door 570 is also pushed open, so as to evacuate from the fire generating area.

In the evacuation process, the first emergency door 510 is first closed between opening the first emergency door 510 and then opening the second emergency door 550. Then, the second emergency door 550 is first closed between opening the second emergency door 550 and opening the third emergency door 570. Finally, when the third emergency door 570 is opened and exited, the third emergency door 570 is finally closed.

At this time, in order to release the locking state of the fitting member 620 hanging in the locking groove 611, the third emergency door 570 is lifted up, and the play between the fastening means 576 and the fastening hole h2 is increased. As the third emergency door 570 is easily lifted up (see FIG. 7), the fitting member 620 caught in the locking groove 611 is easily pulled out, so that the third emergency door 570 is finally removed. Open and evacuate (see Figure 6).

Then, when the first emergency door 510, the second emergency door 550, the third emergency door 570 is pushed open in the order, the first emergency door 510, the second emergency door 550, the third emergency door. Automatically closing in the order of the door 570 is obvious.

At this time, each of the emergency door (510, 550, 570), each of the reinforcing bar (515, 555, 575) that is the edge portion connecting the upper end and the lower end is inclined, the first emergency door 510, the second emergency door 550 and the third emergency door (570). ) Are overlapped in a zigzag form, and after the first emergency door 510 is opened, the second emergency door 550 and the third emergency door 570 may be easily opened sequentially.

Therefore, evacuators can easily and safely evacuate from the fire-generating area by pushing the emergency doors 510, 550, 570, respectively, sequentially in the evacuation direction.
