Abstract

The present invention relates to a fire door that can be easily identified in the dark, and more specifically, to identify the location of the door of the building that the occupants can enter the outside in the dark when a power outage and fire occurs at night to evacuate quickly It is characterized in that the coating layer coated with a photoluminescent pigment on the surface of the fire door is installed indoors.

Description

Fire door easy to identify in the dark {A fire door}

The present invention is a powder coating of the photoluminescent pigment on the surface of the fire door installed indoors so that the occupants can check the location of the entrance door of the building which can be accessed from the outside in the dark when the blackout and fire occurs at night. It is related with the fire door which formed the coating layer by the general coating which included.

Normally, doors and door frames formed by bending steel plates are installed at generation doors of apartments or front doors of buildings, and should be decorated with harmony with interior and exterior interiors with functionality to maintain flame retardancy and fire protection in case of fire. In particular, household doors of apartment houses, apartments, and multi-family homes are excluded from fire door installations, and there is a risk of damage in case of fire spread. Therefore, legislation is mandated to install household doors as fire doors. Installing on

However, the main function of the conventional fire door is to prevent the spread of the fire, and in case of fire, the heat is transferred to another space to prevent the fire zone from expanding or the smoke generated by the fire from entering or spreading into another area. If there is a power outage, there is a problem that it is difficult for the occupants to find the door because the surrounding is dark.

In addition, in case of a power outage due to fire, even if the emergency light installed on the fire door is turned off, there is no way to check the position of the fire door, so the residents who do not know the position of the fire door have no choice but to go indoors. There is a problem that a safety accident occurs injured by hitting furniture, facilities, etc. located.

Therefore, in case of power failure by fire or at night when power failure occurs due to electric accident, residents should be able to find out the location of fire door and evacuate quickly.

Accordingly, the present invention forms a coating layer with a general coating including a powder coating of the photoluminescent pigment on the surface of the fire door installed in the indoor entrance of the building to generate smoke and power outage during night fire, so that the occupant emits light when the interior is dark. It provides a fire door that is easy to identify in the dark so that you can quickly evacuate to the outdoors after locating the location.

As described above, in the present invention, a fire door installed in a room without a separate lighting device self-illuminates in the dark, so that the occupants or those who are not familiar with the doorway at the time of fire and power failure occurring at night can check the location on the fire door and evacuate quickly. It can be effective.

Therefore, the fire door of the present invention is capable of evacuating the fire and power failure quickly due to the self-illumination in the dark has the effect of preventing a large casualty accident.

Figure 4 is a perspective view showing another embodiment of the fire door of the present invention.

In order to achieve the above objects and effects, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a fire door of the present invention, Figure 2 is a cross-sectional view showing the fire door of the present invention.

The fire door (1) of the present invention is installed at the indoor entrance of the building and includes a powder coating on the surface of the phosphorescent pigment (2) so that the occupants can quickly check the position of the fire door (1) and evacuate to the outside during a power outage at night It is the structure which formed the coating layer 5 by general coating.

On the other hand, the photoluminescent pigment (2) refers to a material having a property of absorbing and accumulating energy sources of natural light and artificial light used in daily life such as mercury lamps, fluorescent lamps, incandescent lamps, and the like to emit fluorescent light in a dark place.

Figure 3 is a cross-sectional view showing another embodiment of the fire door of the present invention, when the phosphorescent pigment (2) to the fire door (1) powder or general coating, the effect is the same because the phosphorescent pigment (2) itself is expensive The manufacturing cost is reduced and the light emission time can be adjusted.

In order to reduce the manufacturing cost and the light emission time as described above, 30 to 70% by weight of the phosphorescent pigment (2) and 30 to 70% by weight of barium (3) are mixed to apply powder or general coating.

Therefore, when a sudden blackout occurs in the interior of the building and becomes dark, the fire door 1 emits light emitted from the photoluminescent pigment 2 to provide psychological stability so that residents can evacuate quickly without embarrassment.

In addition, the photoluminescent pigment (2) is preferably used to the inorganic photoluminescent pigment (2) so that static electricity does not occur in the interior of the building.

On the other hand, barium (3) is one of the alkaline earth metal element, a silvery white soft metal having excellent light transmittance.

Therefore, when the phosphorescent pigment 2 and the barium 3 are mixed to apply powder or general coating to the surface of the fire door 1, the light emitted from the phosphorescent pigment 2 is transmitted through the barium 3.

In addition, the light emission time can be adjusted by varying the amount of barium 3 mixed in the photoluminescent pigment 2.

Example

Luminous Pigment 100% by weight (Luminous Time): 8 hours

50% by weight of phosphorescent pigment and 50% by weight of barium (light emitting time): 2 hours

30% by weight of phosphorescent pigment and 70% by weight of barium (light emitting time): 1 hour

Figure 4 is a perspective view showing another embodiment of the fire door of the present invention.

The present invention does not form a coating layer (5) by applying a powder or general coating to the entire fire door (1), but attaches or integrally a plurality of light emitting decoration (4) to a part of the front surface of the fire door (1) In the state of molding to form a coating layer (5) by powder or general coating a mixture of the photoluminescent pigment (2) or barium (3) only in the light emitting decorative portion (4).

Then, when the interior of the building becomes dark, the entire fire door 1 does not emit light, and only the light emitting decoration part 4 emits light so that the position of the fire door 1 can be easily confirmed.

In addition, the surface of the fire door (1) by forming a photoluminescent pigment (2) or a mixture of the photoluminescent pigment (2) and barium (3) to form a coating layer (5) to mark the doorway at night.

For example, if the door is marked with a luminous pigment (2), both the occupant and the unfamiliar person in the dark can easily find the fire door (1).
