Description

{EQUIPMENT OF FIRE DOOR}

More particularly, the present invention relates to a fire door, and more particularly, to a fire door device capable of preventing a fire door from being opened and closed by a packing member having an opened elastic wing, The present invention relates to a fire alarm device in which sound is sounded.

In general, a fire door is a door installed in an opening to prevent expansion and combustion of a fire in a building, such as a house, an apartment, or an office. The Ministry of Land, Transport and Maritime Affairs publicly announced the rules on the standards of the fire escape structure of buildings such as strengthening the performance standards of fire doors installed in apartment escape spaces and clarifying the width standards of stairs and landings It is expected to be implemented in April 2016. According to the above rule, a performance criterion for keeping the outside temperature of the apartment escape space at 30 ° C or higher and 60 ° C or lower is required for the heat shield performance of the fire door.

These conventional fire doors are simply filled with loess panels, vermiculite panels, super board and cement boards in a hollow rectangular steel plate case, which weighs up to 70 ~ 90 kg, which makes it difficult to carry and construct, There was a problem that children and elderly people had difficulty in opening and closing the fire door.

In addition, the fire door is kept in the door frame and airtight so that smoke and gas generated by the fire can be prevented from leaking, and a sealing structure for preventing heat loss and soundproofing is provided. The sealing structure of such a fire door is shown in Fig. 1 of Korean Registered Patent No. 10-0562039.

1 shows a state in which packing is formed in one corner of the square tubular body toward the other corner and arc-shaped vanes are formed on both sides of the square tubular body, and a plurality of insertion protrusions are formed so as to stably contact the insertion groove of the door frame will be.

When the fire door is rotated and closed around the hinge on one side of the door frame, the corner of the fire door is easy to get into the wing of the packing. When the wing wing is hooked, the fire door is not closed properly The square tubular body was pulled, and the closed end of the packing could be generated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

In addition, the size, line thickness, and the like of the components shown in the drawings to be referred to in describing the present invention may be somewhat exaggerated for convenience of understanding, and terms used in the description of the present invention And therefore, the definition of the terms should be based on the contents of the entire specification of this specification, which may vary depending on the user, the intention of the operator, and the customs.

1 to 5 are views for explaining a fire door device according to the present invention in detail.

As shown in the figure, a fire door frame 10 connected in a rectangular frame shape by four first to fourth frames 10a, 10b, 10c and 10d, and a hinge 21 on one side of the fire door frame 10, 10b, 10c, and 10d of the fire door frame 10 to be closely attached to the fire door 20 when the fire door 20 is closed And a packing member (30).

The first to fourth frames 10a, 10b, 10c and 10d are plate profiles bent so that the outer side is open, and the first side 11 and the second side 11b, which are orthogonal to each other for seating at least the fire door 20, A second surface 12 is formed and a trapezoidal groove 13 is formed between the first surface 11 and the second surface 12 of the door.

Particularly, the fourth frame 10d is provided with the first end stop 14 so as to receive the door wing 22 of the fire door 20 and not protrude to the outside of the fire door frame 10. This configuration is such that when the fire door 20 is rotated about the hinge 21 and closed, the door wing 22 of the fire door 20 is recessed into the first end groove 14, It is possible to secure an elegant fire door device.

The packing member 30 includes a first packing member 30a assembled to the second frame 10b forming the fire door frame 10, that is, a frame on the hinge side, and first, third, 4 frames 10a, 10c, and 10d, respectively.

The first packing member 30a includes a first packing body 31a having a trapezoidal cross section that is fitted in a trapezoidal groove 13 of the second frame 10b and a second packing body 31b having a trapezoidal cross- And is formed as a first elastic blade 32a extending in a translational direction toward the edge of the first elastic blade 32a.

The second packing member 30b includes a second packing body 31b having a trapezoidal cross section and fitted in the trapezoidal grooves 13 of the first, third and fourth frames 10a, 10c and 10d, And a second elastic blade 32b of an inverted U-shaped shape extending upward from one corner of the body 31b and extending downwardly.

The second frame 10b on which the first packing member 30a is assembled is provided on one side of the fire door 20 with a second seal member 30a, A step groove 23 is provided. The second stage tongue 23 having such a configuration is provided on the second side of the door 20 only when the door 20 is closed when the door 20 is rotated about the hinge 21, So that the portion of the step groove 23 is touched and pressed tightly.

The second packing member 30b is provided on the second surface 12 of the first, third and fourth frames 10a, 10c and 10d with the second elastic wing 32b of the second packing member 30b supported The second elastic wing 32b is formed in an inverted U-shape in which one side of the fire door 20 is open when the fire door 20 is rotated about the hinge 21, So that the second elastic wing 32b of the second packing member 30b can reliably come into close contact with the edge portion of the fire door 20 without getting wet.

The first and second packing bodies 31a and 31b of the first and second packing members 30a and 30b are formed to have a trapezoidal cross section so that the first to fourth frames 10a to 10d 10b, 10c, 10d from the trapezoidal grooves 13 of the first to fourth frames 10a, 10b, 10c, 10d so that the first and second packing members 30a, 30b The first and second packing bodies 31a and 31b of the first and second packing bodies 31 and 32 do not come off or come off.

As described above, when the fire door 20 is closed, the corner of the fire door 20 prevents the first and second elastic wings 32a and 32b from entering the door, The elastic wings of the packing are elastically pressed and tightly adhered to each other, thereby preventing heat loss as well as soundproofing.

The fire door 20 is formed by a seam in which both ends of the first plate 23 and the second plate 24 are fitted to each other and pressed and fixed. The thickness of the fire door 20 is about 45 mm, It is preferable that the loam panel 25 and the flameproof styrofoam 26 are installed so as to secure the heat shielding performance of the fire door according to the rules on criteria such as the evacuation fire prevention structure. At this time, the loess panel 25 is about 15 mm and the flameproof styrofoam 26 is about 30 mm, so that the heat-shielding performance of the fire door can be ensured and the weight can be reduced.

If the louver panel 25 and the flameproof styrofoam 26 are built in the inside of the fire door 20 as described above, the weight of the fire door can be reduced by 40 to 50% And it is also possible to secure the heat shield performance of the fire door according to the rules on criteria such as the evacuation fire structure of the building.

The trapezoidal grooves 13 formed between the first surface 11 and the second surface 12 of the first to fourth frames 10a, 10b, 10c and 10d constituting the fire door frame 10, The first and second packing bodies 31a and 31b of the packing member 30 are also formed in the arcuate grooves 16 as shown in FIG. It should be formed of a third packing body 31c of an arc shape corresponding to the shape. If the arc-shaped groove 16 and the arc-shaped third packing body 31c are formed as described above, any shape can be used as long as the shape prevents the third packing body 31c of the packing member 30 from being pulled out or separated as well as the trapezoidal shape. will be.
