JP3672263B2 - Evacuation guidance device for disasters in buildings - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to an evacuation guidance device at the time of disaster in a building.
[0002]
[Prior art]
Conventionally, in this type of guidance device, when performing evacuation guidance, a fire place is sensed by a sensor installed in the building, and evacuation guidance is performed by voice, flashing light, or the like in a direction away from it.
[0003]
[Problems to be solved by the invention]
However, in the conventional evacuation guidance device, it is assumed that the place where the fire occurred is a point detected by the sensor, and since the detection range is a point, there is a possibility that the exact place where the fire has occurred cannot be grasped. In addition, since it is based on the judgment of the sensor, the movement of smoke, the degree of danger, etc. cannot be judged, and there is a possibility that evacuation guidance may not be performed based on accurate judgment.
[0004]
In addition, fire doors are always installed in the openings on the fire compartments stipulated by the Building Standards Act, and all the fire doors are closed in the event of a fire. I didn't understand without trying.
The present invention has been proposed in view of the above-described problems of the prior art. The purpose of the present invention is to improve the reliability of evacuation guidance, to lower the installation cost, and to be easily installed in an existing building. The point is to provide an evacuation guidance device in case of disaster.
[0005]
[Means for Solving the Problems]
Order to achieve the object, the evacuation device disaster in a building according to the present invention, traffic at the time of dividing the evacuation routes in buildings into a plurality of sections, evacuees moves from one compartment to another compartment (collectively "glass door" would leave) fire door using the door or see-through glass with a see-through glass into the opening between the compartments which is arranged, the lighting of each compartment during a fire Control the brightness of the door or fire door glass located in the opening between the current section of the refugee and the safer section adjacent to it, as viewed from the side of the current section. It is characterized by being made larger than the brightness of the periphery , floor, and ceiling surface of the glass portion .
[0006]
In the invention of claim 2, when the glass door is in a poorly closed state and smoke from the fire chamber enters the stairs through the opening where the glass door is installed, the sensor is installed in the stairs. and it is configured to provide a control device to drop the lighting in the staircase as well as detect the smoke Te.
[0007]
[Action]
In the present invention, as described above, a door using a see-through glass or a fire door using a see-through glass is disposed in an opening between sections where evacuees in a building pass , and when a fire occurs, The brightness when viewing the glass part of the door or fire door located at the opening between the current section of the evacuees and the safer section adjacent to it from the side of the current section is the glass in the current section. since the portion of the peripheral or floor, is greater than the brightness ceiling surface, evacuation using Kokosei that escapes towards bright when human evacuation is performed.
[0008]
The invention of claim 2 is that the glass door becomes poorly closed due to deformation of the building at the time of an earthquake disaster, or has been kept open due to daily use, etc., so that the smoke from the fire chamber is glass When entering the stairs through the door opening, the sensors installed in the stairs work to turn off the lights in the stairs and inform the evacuees that the stairs are darker than other spaces and dangerous. Can do.
[0009]
【Example】
The present invention will be described below with reference to illustrated embodiments.
As shown in FIG. 1, the evacuation route in the building is divided into a plurality of sections, and the sections in the illustrated example are a total of four sections: a living room 1, a corridor 2, a staircase 3, and a staircase 4.
When a fire breaks out of the building and evacuates from the living room 1, the lighting in each section is controlled, and the lighting in the space is changed to the living room 1 → first safety section (corridor 2) → second as shown in FIG. The lighting is increased in the order of the secondary safety zone (steps 3 and 4) . In addition, in the openings between the living room 1 and the hallway 2 and between the hallway 2 and the stairs 3 and 4 , which are openings between the compartments when the evacuees move from one section to another section , the glass door 5 with a see-through glass keep disposed.
[0010]
A glass fire door is used on the fire prevention compartment. Thus, when the refugee 6 in the living room 1 evacuates, the glass portion of the glass door 5 disposed in the opening between the current division of the refugee 6 and a safer division adjacent to the evacuator 6 is placed on the side of the current division. The brightness when viewed from above is made larger than the brightness of the periphery, floor, and ceiling surface of the glass portion in the current section .
Accordingly, when the refugee 6 evacuates, the brightness of the glass portion of the glass door 5 disposed in the opening to the safer space becomes larger than the brightness around the opening of the current space where the refugee is located. Evacuation guidance is performed in a safe and orderly manner using the light-transmitting property of human behavior.
[0011]
In addition, the glass door remains open due to poor closure of the glass door due to deformation of the building after an earthquake disaster, or when a glass door is kept for daily use. Even if you enter the staircase 4 through the opening where the door is installed, the sensor installed in the staircase works and the lighting in the staircase turns off, making the staircase darker and more dangerous than other spaces Can be reported to the evacuees 6.
[0012]
In addition, even if the sensor breaks down, the entrance to the stairs 4 can be seen through the glass door 5 made of glass that can be seen through, so the refugee 6 can confirm that the stairs 4 is dangerous. It can be judged before opening and can prevent accidents.
[0013]
【The invention's effect】
As described above, the evacuation guidance device for a disaster in a building according to the present invention divides the evacuation route in the building into a plurality of sections, and the evacuee moves between one section and another section when passing from one section to another section. A glass door made of transparent glass is installed in the opening, and the lighting of each section is controlled in the event of a fire , and is placed in the opening between the current section of the evacuees and the safer section adjacent to it. by brightness when viewed settings glass portion of the glass door from the side of the current partition, and around the floor of the glass portion of the current in the compartment, and to be larger than the brightness of the ceiling surface, human evacuation Since the evacuees themselves can determine the evacuation direction by using the light-transmitting property as the behavior, the reliability of the evacuation guidance device is improved.
[0014]
In addition, since the glass door itself is large, the see-through portion is large and easy to see, and it becomes a guide light itself.
Furthermore, since this apparatus is based on the combination of the sensor and illumination installed on each member, a complicated control system is not required and the installation cost is low.
Furthermore, according to the present invention, the present apparatus can be installed in an existing building simply by replacing a door or door, a lighting fixture, and a sensor.
