The present invention relates to the automatic closing and evacuation of the evacuation door of the fire screen shutter, more specifically in the direction to be closed at all times by installing a tension coil spring between the lower frame of the shutter shutter lower frame and the lower door of the evacuation door By allowing the force to be applied to the evacuation door, it not only induces the automatic closing of the open evacuation door but also improves the sealability of the lower edge of the evacuation door through the pressing force in the sealing direction. By installing the upper cover attached to the cable so that it can be connected to the evacuation door in a wired state, it reinforces the sealing force at the upper edge of the evacuation door without affecting the opening / closing operation of the evacuation door at all. The light can more effectively block external leaks, so By minimizing the damage of the evacuator, it is possible to improve the reliability of the product.

In general, fire and smoke shutters literally block smoke and endure flames, so when a fire breaks out in a building, the people who evacuate the building gain time and prevent the flames from spreading and moving across the building. In order to resist the flame for a certain time,

In the past, it was common to provide a fire prevention shutter or a flame retardant shutter separately, and if the building has only a smoke shutter, smoke and toxic gas generated in a fire are lighter than air, so they float upwards and spread out on the ceiling. In order to prevent this, by installing a smoke-controlled boundary wall in the middle of the ceiling, the toxic gas can be trapped for a while to reduce the rate at which smoke and toxic gases spread, but the smoke can be prevented for a while, but the flame cannot spread to the entire building. Not very practical,

On the other hand, fire doors or fire shutters are made of thick steel because they have to withstand high temperatures for a long time. When a smoke sensor or a heat sensor detects a fire, it sends this signal to a fire detection interlock controller. In principle, if the fire shutter is closed too early, the interlock controller will close after the fire detection has given enough time to evacuate all the people inside. In order to prevent this, a separate evacuation door may be installed on the side of the fire shutter. However, the cost of the evacuation door is added to the construction of the evacuation door, which is not properly observed.

In addition, steel fire doors or fire shutters are designed to be used repeatedly, but when used several times, deformation occurs due to the high temperature of the flames, causing gaps in the closed areas, resulting in unstable opening and closing of flames or smoke. There are drawbacks to this.

In view of the above problems, in recent years, flame retardant and flame retardant are carried out at the same time, but it is known that a flame retardant screen shutter is constructed using a flame retardant fabric which is easy to manufacture and low cost. The installation of the evacuation door based on the standard is essential. For this purpose, the existing flame-retardant screen shutters are known as the evacuation door and the structure for opening and closing the same as shown in FIGS. 11 to 12, which will be described in more detail.

When the evacuation door of the structure as shown in Figure 11 is inclined state of the open line is narrow in the upper portion and the lower portion is wide when the evacuation door 100 rotates around the inclined hinge at the lower end to form a passage space When a lot of people escape to the emergency door in the form of a triangle, there is a problem that many casualties occur because of bottlenecks do not escape quickly.

In addition, the evacuation door 100 is closed by the inclined hinge itself, but there is no structure that can be in close contact with the evacuation door 100 forcibly on the screen, due to lack of airtightness between the evacuation door 100 and the screen There is a high risk of gaps in the structure, and the structure that can reinforce the sealing force of the evacuation door 100 is only the side cover 101, which is also a structure that can only support the lower edge of the evacuation door 100 by pressing the seal Toxic gas, soot, and flames are leaked due to the drop, and they are not applied due to insufficient installation standards.

In order to improve the problems as described above in Figure 12 for the purpose of reducing the casualties by allowing many people to evacuate quickly by opening the emergency door, the emergency door (100A) that the person can escape in the center of the fire screen Is disposed, and the upper frame (100A ') for holding the emergency door (100A) in the longitudinal direction is disposed on the upper end of the emergency door (100A), the upper portion and the side of the emergency door (100A) is toxic on the opposite side in case of fire First and second smoke barriers are installed to prevent gas from leaking into the gap, and hinges are installed on the upper and lower ends of the emergency door so that the emergency door can be opened at an angle of 90 °. Although it is known as -0414728, this constitutes a rectangular passageway through which the evacuator can pass, and the problem as shown in FIG. 11 can be solved.

Also, as shown in FIG. 11, only the third smoke blocking membrane 101 ′ reinforces the sealing force of the side portion of the emergency door 100A through the third smoke blocking membrane 101 ′ and imparts force in the direction to be closed to the emergency door 100A itself. Since there is no structure and there is no structure for sealing and reinforcing the upper edge of the emergency door 100A, there is a disadvantage that a flame or smoke may flow due to a gap between the emergency door 100A and the fire screen due to deterioration of airtightness. .

The present invention has been made to solve and solve all the problems caused by the existing in the above,

It is an object of the present invention to induce automatic closing of an open evacuation door, as well as to improve the sealability of the lower edge of the evacuation door through the pressing force in the sealing direction, and also to seal the upper edge of the evacuation door without affecting the opening and closing operation of the evacuation door at all. Fire retardant screen shutter which can improve the reliability of the product by minimizing the transfer of fire and minimizing the damage of evacuation by toxic gas, soot, flame etc. Provides automatic closing and evacuation reinforcement structure

In order to achieve the above object, the present invention provides a tension coil spring between the shutter lower frame of the bottom of the screen shutter and the lower frame of the bottom of the evacuation door so that the force in the direction to be closed at all times can be applied to the evacuation door. In addition, the upper cover is attached to the screen shutter to the upper edge portion of the evacuation door directly connected to the evacuation door to operate through the wire,

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Both ends are fixed to the shutter lower frame 1A at the lower end of the screen shutter 1 and the lower frame 3B at the lower end of the evacuation door 3 to impart a constant pulling force to the evacuation door 3 in the closing direction. Each of the tension coil spring 51 is to include a refuge door tension member 50 is configured by integrally connecting the flexible connection wire 52 to one end.

※ Unexplained code in the drawing ※

70 is composed of the plate member 71 and the wire 72 is coupled to show the closing induction member is installed between the lower frame of the shutter shutter frame and the lower frame 4A of the side cover (4).

Referring to the operation of the present invention configured as described above in detail as follows.

The upper cover stand 20 of the present invention is composed of a flame-retardant fabric in the same way as the screen shutter (1) and the frame and evacuation door (3) and side cover (4) and the top cover applied to the screen shutter (1) All the frames applied to the base 20 can keep the flame-retardant fabric tight and give proper contact pressure to help hermeticity and when holding means using magnetic force additionally configured to reinforce hermeticity are applied. It is suitable to be composed of a metal material having an appropriate weight in preparation for.

In addition, the evacuation door support wire 10 and the cover operation wire 30 is also configured using a heat resistant strong steel wire.

On the other hand, when a fire occurs in the building, the rated power is automatically cut off by a heat sensor or combustion detector attached to the ceiling, and as the emergency power is supplied, the fire screens installed in each section of the building descend to block the spread of the fire.

3, 6, and 8 are views in which the evacuation door 3 is blocked in the state where the fire screen shutter of the present invention is lowered.

The lower edge of the evacuation door (3) is in close contact with the shutter lower frame (1A) of the screen shutter (2) by the pulling force of the evacuation door tension member 50 and the open end side of the evacuation door (3) is a side It is covered by the cover 4,

The lower frame 4A of the side cover 4 is in a state in which a force is applied in the direction in which the lower frame 3B of the evacuation door 3 is pressed by the tension hinge 4B and the upper cover stand 20 is pressed. Is covering the upper edge of the evacuation door (3), the upper and lower side portions of the evacuation door (3) is in close contact with the screen shutter (1) and covered through the side cover (4) and the upper cover (20) The airtightness is maintained to prevent leakage of toxic gas, soot and flames from the fire area into the evacuation area.

 Meanwhile, the bar 60-type magnet 60 is integrally attached to the inner surface of the upper cover 20 in the width direction so that the upper frame 3A and the upper frame 3A of the evacuation door 3 are attached to each other through the magnetic force. The upper side of 3) has the effect of reinforcing additional airtightness.

In this state, if the evacuation door is forced to push the evacuation door 3 to escape from the fire-generating area, the evacuation door 3 is opened while being rotated outward through the hinge 3C. 50 is forcibly stretched to maintain a state in which the tensile force is increased, wherein the evacuation door support wire 10 fixed to the outer end of the upper frame 3A is made of fabric paper and difficult to maintain the fixed form of evacuation door ( The upper outer part of 3) catches the sag below.

When the evacuation door 3 is opened and rotated, the cover operation wire 30 fixed at both ends of the outer frame of the upper frame 3A and the cover frame 21 of the upper cover 20 is also as in the arrow of FIG. 2. The upper cover 20 is lifted upward by the opening angle of the evacuation door 3 so that it does not come into contact with the upper cover 20 in the process of opening the evacuation door 3. It does not interfere with the opening operation and the evacuation door (3) is to be opened to the extent that the upper cover (20) is completely flipped to contact the screen shutter (1).

On the other hand, when the evacuation door (3) is opened as described above, the free end side of the lower frame (3B) of the evacuation door (3) is forcibly pushed while contacting the inner surface of the side cover (4) that is covered thereon and thereby the side cover (4) is rotated with respect to the tension hinge (4B) is opened so as not to interfere with the opening of the evacuation door (3), the tension hinge (4B) is the opening angle of the side cover (4) is a predetermined angle or more Automatically applying the tension in the opposite direction to open at a set maximum angle without a separate external force is one of the known functional hinges that are already applied in various fields.

On the other hand, if the escape of the evacuation is completed through the open evacuation door (3) and there is no opening pressure applied to the evacuation door (3), the tension door of the evacuation door tension member (50) in the closing direction to the evacuation door (3) The upper cover for covering the evacuation door (3) during the closing process of the evacuation door (3) is generated by the rotation moment is generated and close to the surface of the screen shutter (1) as the initial rotation while rotating about the hinge (3C) The stand 20 and the side cover 4 are interlocked in the closing direction, which will be described in more detail.

First, when the evacuation door (3) is rotated in the closing direction, the pulling force to the cover operation wire 30 fixed to the outer end of the upper frame (3A) is eliminated and thereby the upper cover (20) is closed by its own weight The length of the cover operation wire 30 connected to the upper cover stand 20 is pulled and pulled so that the evacuation door 3 is closed and moved to be absorbed while the upper cover stand 20 is leaned. The wire 30 is maintained in a tense state without being folded, regardless of opening and closing of the evacuation door (3), it is possible to perform an accurate transmission function.

On the other hand, when the side cover 4 is completely open, the closing guide member 70 constituted by the plate member 71 and the wire 72 is exposed to the outside at the inner edge of the side cover 4, and as shown in FIG. It is kept straight.

When the evacuation door 3 is rotated in the closed direction in this state, the end of the evacuation door 3 is rotated inward by pressing the plate member 71 as shown in FIG. 10 while the wire 72 connected thereto is dragged inward. The side cover 4 connected to the wire 72 is forcibly rotated in the closing direction. In this case, when the closing angle of the side cover 4 is more than a predetermined angle, tension in the opposite direction is automatically applied to the evacuation door without a separate external force. It pushes and closes until it comes in contact with the lower frame 3B of (3).

The upper cover 20 and the side cover 4 is a structure that can not be closed earlier than the evacuation door (3) in the structure does not interfere with the closing operation of the evacuation door (3), of course.

In the above, one embodiment of the present invention has been described, but modifications and variations within the scope without departing from the technical spirit of the present invention by those skilled in the art belong to the scope of the present invention Of course.

The present invention as described above induces the automatic closing of the open evacuation door through the tension coil spring installed between the metal frame at the bottom of the screen shutter and the bottom of the evacuation door, as well as the sealing property of the lower edge of the evacuation door through the pressing force in the sealing direction Also, the upper edge of the evacuation door is attached to the screen shutter directly above the evacuation door, and is connected to the evacuation door through wires so that the opening and closing operation of the evacuation door can be prevented. By reinforcing the sealing force of the upper edge part, toxic gas, soot, flame, etc. in the fire place can effectively block external leakage, which can improve the reliability of the product by minimizing the transfer of fire and minimizing the damage of the evacuator. It works.
