Description

FIREPROOF DOOR CAPABLE OF DETECTING FIRE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fire door, and more particularly, to a fire door capable of recognizing a temperature change caused by a fire by means of visual (visual) or auditory sense, To a fire door capable of detecting a fire temperature that can prevent secondary damage such as a back draft.

In the event of a fire, personal injury caused by a fire is much more likely to be caused by fire or flame spreading due to fire heat or fire than to casualties caused at the place where the fire occurs.

Therefore, it is essential that safety devices are installed in various buildings in order to prevent the spread of fire and to protect human life. One of the measures to prevent the spread of fire is to prevent the fire from moving into other spaces and expanding the fire area or the smoke generated by the fire from entering or diffusing into other areas. And a fire door is installed between the spaces.

Conventional fire doors are required to be closed at all times so that smoke or heat can be blocked, so door closures are provided on fire doors and door frames to maintain the closed state of fire doors.

On the other hand, if a fire occurs in an enclosed space, oxygen will be deficient in the state of fire without combustion, and if oxygen is rapidly introduced into the closed space, a large amount The back-draft phenomenon (explosion of smoke) in which carbon monoxide and other combustible gases are exploded is inevitably generated.

Accordingly, when a fire occurs in any one of two closed spaces divided by a fire door that is kept closed at all times, if the fire door is opened in another space where no fire occurs, Sudden combustion or explosion due to the back-draft phenomenon occurs.

As a result, there is a problem that it can cause serious injury to a person who opens the fire door for fire escape or fire escape in the event of a fire, and also causes a sudden spread of fire. In order to compensate for this, a fire door having a fire detection function has been developed as shown in the following Patent Document 1, but a complicated structure has to be added to the existing fire door, resulting in cost increase in actual application.

A fire door (hereinafter referred to as a 'fire door') capable of detecting a fire temperature according to a preferred embodiment of the present invention allows a temperature change caused by a fire to be recognized through visual (auditory) , Especially to avoid the secondary damage such as the back draft due to the opening of the fire door when evacuees are evacuated due to the fire. In other words, the fire door of the present invention is provided as a safety device that can prevent a second person from experiencing second-degree damage regardless of the intention of the person, such as a back draft, when the second person is evacuated.

As shown in FIG. 1, the fire door according to the embodiment of the present invention divides an internal space of a building to block the propagation of a fire when a fire occurs. The fire door includes a fire door 100 and a fire door 100, And a plurality of visible markers 200 that are separately displayed on the surface of the fire door body 100 in response to changes in the fire temperature.

The fire door body 100 is made of an ordinary steel material, and the surface thereof is painted with mostly dark blue color pigments. The visibility marker 200 is displayed on the fire door 100 when the occupant is evacuated in the event of a fire as described above and the temperature change of the space around the fire door 100 and the fire door 100 is visually It is easily identifiable. In other words, when the visibility mark 200 is displayed on the fire door body 100, the occupant can judge that the fire temperature is equal to or higher than a predetermined temperature. In this case, the fire door body 100 is not opened, Occurrence can be prevented. It is preferable that the visibility marker 200 is not separately displayed on the fire door body 100 so that the occupant can not be visually confirmed or hard to see when the fire is not generated.

In the present invention, as shown in FIG. 1, the visibility marker 200 may be formed of at least one of a phrase and a pattern, and is provided by painting a pigment on the fire door body 100.

Here, it is preferable that the pigment forming the visibility marking 200 is applied as a thermochromic pigment whose color changes when the temperature of the space around the fire-fighting door body 100 or the fire-shielding door body 100 reaches a set temperature. In addition, the thermosensitive pigment forming the visibility marking (200) can be used as a flame or sunlight-luminescent pigment or a glittering pigment so as to enable the occupant to visually recognize the display of the phrase or the pattern even in the dark state of the room due to a fire. . Therefore, it is impossible to confirm the visibility mark 200 that the occupant sees in the dark indoor space or at night, and the fire safety door body 100 is opened to cause the secondary safety damage like the back draft It is possible to further prevent it.

In the present invention, it is preferable that the thermosensitive pigment forming the visibility mark 200 is applied as a pigment in which the hue of the fire door body 100 is changed in color with a color of a complementary color with the color of the painted color (paint) . For example, if the fire door body 100 has a dark blue color, the thermochromic pigment forming the visible mark 200 may be applied as a yellow or yellowish pigment. Accordingly, there is an advantage in safety that the occupant can more easily confirm the visibility mark 200. [

In the present invention, as shown in FIG. 2, the visibility markers 200 may be provided in plural numbers so as to be spaced apart from each other in the left-right direction or the vertical direction of the fire-fighting door body 100.

In other words, for example, the visibility markers 200 may be provided three in the vertical direction of the fire door body 100, in which case the thermo-sensitive pigments forming each of the three visibility markers 200 are not applied equally. Specifically, the thermochromic pigments forming the three visibility markers 200 are each applied with different set temperatures at which the hue varies, for example, the thermochromic pigments forming the uppermost visibility mark 200 are approximately 40 degrees And the lower temperature visible pigment 200 may be applied as a color change at a temperature of approximately 60 degrees (moderate temperature), and the lowermost visibility mark 200 ) Can be applied in which the color changes at a temperature of approximately 100 degrees (high temperature).

In this case, the three visibility markers 200 can be sequentially displayed on the fire door body 100 in the form of a phrase such as " fire generated ", " open / closed prohibited & have. If the fire temperature is approximately 40 degrees, only the text "Fires" is displayed. If the fire temperature rises to approximately 100 degrees, the words "fire", "open / close" and "no access" are all displayed. The occupant can visually confirm that the lowermost " Approach prohibited " phrase is displayed and thereby prevent access to the fire door body 100 at the source.

On the other hand, the reversible thermosensitive pigment is a pigment which changes its color at a designated temperature and is restored to its original color when the temperature is lowered. The irreversible thermosensitive pigment is a pigment which maintains a changed color even when the temperature falls. In the present invention, it is preferable that the thermosensitive pigment forming the visibility mark 200 is applied as a non-reversible thermosensitive pigment which irreversibly acts on the fire temperature change. In this case, even if the temperature in the space around the fire door body 100 becomes low, It is possible to prevent damage such as a vapor explosion due to the opening of the fire door body 100 due to the presence of vapor in the space.

In the present invention, it is preferable that the plurality of temperature-changing pigments are each applied with electrical conductivity. This will be described in detail below.

3, the fire door according to the present invention includes a fire detection unit 300 for detecting at least one of temperature change, fire smoke generation, and oxygen concentration change in the space around the fire door or the fire door, A control unit 500 for receiving the sensed value of the fire sensing unit 300 and controlling on / off the driving of the fire alarm unit 400, a fire alarm unit 400 for generating a fire alarm and applicable as a speaker or an LED alarm, As shown in FIG.

Here, the fire detection unit 300 may be installed in the fire door body 100, installed on the outer surface of the fire door body 100, or may be installed in a peripheral structure adjacent to the fire door body 100. In this way, the fire detection unit 300 can be integrally formed with or separate from the fire door body 100, but can be integrally manufactured.

In the present invention, the fire sensing unit 300 includes a fire sensor 100 and a temperature sensor for sensing a temperature change of a surrounding space, a fire toxic gas such as carbon dioxide, hydrogen sulfide, etc., And an oxygen sensor for measuring the oxygen partial pressure of the air around the fire door body 100 according to the fire occurrence. In addition, the fire sensing unit 300 may be a combination of at least two of a temperature sensor, a smoke sensor, and an oxygen sensor. In this case, Can be detected. For example, when the detection value of the temperature sensor is approximately A and the gas detection concentration of the smoke detection sensor is approximately B, the control unit 500 compares the fire detection range satisfying the values A and B with the set reference value, The degree of occurrence can be judged.

The fire alarm unit 400 may be configured to provide auditory or other visual recognition methods to the occupant in addition to visual recognition of the occupant's visibility mark 200 and may be applied as a speaker or / and an LED alarm.

The control unit 500 receives the sensed value of the fire sensing unit 300 and controls the fire alarm unit 400 to be turned on and off. Specifically, if the detection values of the temperature sensor, the smoke sensor, and the oxygen sensor are detected to be out of the reference setting range, the control unit 500 can output a warning warning broadcast through a speaker and emit a warning light through an LED alarm light . Here, it is preferable that the intensity of the light emitted from the LED alarm light has such a brightness as to be recognizable by the visually impaired.

The control unit 500 outputs a warning warning message such as " a fire has occurred, do not open the fire door ", etc. through the speaker, so that the present invention can prevent the visually impaired person from opening the fire door body 100 according to the occurrence of fire.

As described above, the thermochromic pigment forming the visible marking 200 can be applied as having electrical conductivity. In this case, the fire detection unit 300 such as a temperature sensor, a smoke detection sensor, an oxygen sensor, etc. may be omitted.

In this case, as shown in Fig. 4, the control unit 500 senses changes in the resistance values of the plurality of (three) temperature-transition pigments and detects whether or not the three resistance value changes are within the respective setting ranges The driving of the speaker or / and the LED alarm can be controlled on / off based on the sensed value. Specifically, when the temperature-dependent pigment has electrical conductivity, when the temperature of the fire door body 100 changes according to the occurrence of a fire, a change occurs in the current value through the temperature-dependent pigment. At this time, the control unit 500 senses a change in the resistance value of the thermo-sensitive pigment part of the visibility marker 200 and compares the sensed value with the normal set resistance value range, and then drives the speaker or / and LED warning light do.

According to the present invention, the visually impaired or hearing-impaired person can more effectively perceive the fire state according to the difference in the degree of fire, that is, the environment change such as the early stage of the fire (the fire door temperature low temperature described above), the middle stage (middle temperature) An additional control method is applied.

Specifically, the controller 500 senses changes in the resistance values of the three thermochromic pigments, respectively, and selectively controls driving of the fire alarm unit 400 according to the degree of the three resistance values.

The control unit 500 sets the value of the signal value comparing unit 600 for determining whether the resistance value of the thermosensitive pigment having the relatively high temperature temperature range is varied among the three thermosensitive pigments forming each of the three visibility markers 200 Based on this, the output value of the speaker is increased or decreased, and the intensity of the LED alarm light is adjusted.

For example, when the color of the visible pigment 200 (middle mark in the drawing) corresponding to the relatively hot fire temperature is changed, the control unit 500 senses the color and outputs the output of the speaker or the brightness of the warning light . In addition, when the color of the visible pigment 200 (the lowest mark in the drawing) which is responsive to the fire temperature of the relatively high temperature is changed, the controller 500 senses the change of the color of the output of the speaker, .

Although the present invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the present invention is not limited thereto but is limited by the following claims. Accordingly, those skilled in the art will appreciate that various modifications and changes may be made thereto without departing from the spirit of the following claims.
