Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evacuation guidance device for a disaster in a building.

[0002]

2. Description of the Related Art Conventionally, in this type of guide device, when evacuation guidance is performed, a sensor installed in a building detects a fire place and guides evacuation in a direction away from it by voice or blinking light. Was there.

[0003]

However, in the above-mentioned conventional evacuation guidance system, it is assumed that the place where the fire is generated is the point where the sensor detects it, and since the detection range is the point, the accurate place where the fire occurs is determined. There was a possibility that I could not grasp. Also, because it is based on the judgment of the sensor,
It was not possible to judge the movement of smoke and the degree of danger, and there was a possibility that evacuation guidance could not always be made based on accurate judgment.

In addition, a fire door is always installed at the opening on the fire prevention section stipulated in the Building Standards Act, and all the fire prevention doors are closed at the time of a fire, so whether or not the guide space is safe. I couldn't find out without opening the door. The present invention has been proposed in view of the problems of the above-mentioned prior art, and the purpose thereof is to improve the reliability of evacuation guidance,
The point is to provide an evacuation guidance device at the time of a disaster that has a low installation cost and can be easily installed in an existing building.

[0005]

In order to achieve the above-mentioned object, the evacuation device for a disaster in a building according to the present invention is
On the evacuation route in the building, a transparent glass door or fire door (hereinafter collectively referred to as "glass door") is provided at the opening to a safer compartment than the current compartment, and The brightness of the opening to the partition is configured to be larger than the brightness of the side surface, floor, or ceiling surface of the opening.

According to a second aspect of the invention, when the glass door is in a poorly closed state and smoke from the fire generating chamber enters the stairs through the opening in which the glass door is installed, the smoke door is installed in the staircase. It is configured with a control device that detects the smoke through a sensor and turns off the illumination inside the stairs.

[0007]

In the present invention, as described above, a door using transparent glass or a fire door using transparent glass is provided at the opening to the safer compartment than the current compartment in the evacuation route in the building. Since the brightness of the opening is set to be higher than the brightness of the vicinity of the opening, evacuation guidance is performed by utilizing the light directional property that a person escapes to a brighter side during evacuation.

According to the second aspect of the present invention, the glass door is in a poorly closed state due to deformation of the building at the time of an earthquake disaster, or is left open because a pet is kept for everyday use. If smoke enters the stairs through the opening of the glass door, a sensor installed in the stairs will turn off the lighting inside the stairs, and the evacuees will find that the stairs are darker than other spaces and dangerous. Can be informed.

[0009]

The present invention will be described below with reference to the illustrated embodiments. When a fire occurs in a building and you evacuate from the living room 1, the lighting in the space is changed from the living room 1 to the primary safety compartment (corridor 2) to the secondary safety compartment (stairs 3 and 4) as shown in FIG. ), And the glass door 5 made of transparent glass is provided in the opening between the living room 1 and the corridor 2, and between the corridor 2 and the stairs 3 and 4.

A glass fire door is used on the fireproof compartment. Thus, when the evacuee 6 in the living room 1 evacuates, the brightness of the opening to the safe space is made higher than the brightness around the opening. Therefore, when the evacuee 6 evacuates, the brightness of the opening to the safer space becomes larger than the brightness around the opening of the current space where the evacuees are located, and therefore the light directional property as human behavior during evacuation is used. , Evacuation guidance is performed safely and in an orderly manner.

[0011] In addition, when the glass door is not closed properly due to the deformation of the building after the earthquake disaster, or when the glass door is kept for everyday use, the glass door remains open.
Even if smoke from the fire room enters the staircase 4 through the opening where the glass door is installed, the sensor installed inside the stairs will work and the lighting inside the stairs will be turned off. It is possible to inform the evacuees 6 that it is darker and more dangerous than the space.

In addition, even if the sensor fails, the entrance to the stairs 4 can be seen through the glass door 5 made of transparent glass, so that the evacuees 6 know that the stairs 4 are dangerous. It is possible to judge before opening the glass door and prevent accidents.

[0013]

As described above, the evacuation guidance apparatus for a disaster in a building according to the present invention uses a glass door using a transparent glass in the opening to the safer section than the current section in the evacuation route in the building. The brightness of the opening is
The evacuees themselves can judge the evacuation direction by using the light directional property as human behavior during evacuation by making it larger than the brightness of the side surface, floor, and ceiling surface of the opening.
The reliability of the evacuation guidance system is improved.

Further, since the glass door itself is large, the see-through portion becomes large, and it is easy to see, and it becomes a guide light itself, so that the evacuation guidance effect is improved. Furthermore, since this device is a combination of a sensor and lighting installed on each member,
No complicated control system is required and installation cost is low.
Furthermore, according to the present invention, this device can be installed in an existing building by a simple construction by simply replacing the door or door, the lighting fixture, and the sensor.
