JPH0496769A - Building using elevator hall as temporary refuge room - Google Patents

Abstract

PURPOSE:To directly use an elevator for everyday use as a refuge device by providing a fire limit in an elevator hall, and providing an electric system for controlling the drive of the elevator independently of the electric system of a building. CONSTITUTION:Should an emergency such as a fire and the like occur in a building main body 3, people in each room of the building main body 3 temporarily take refuge in an elevator hall 9. Since the elevator hall 9 is constructed into fireproof construction together with an elevator 7, the fire would not stret to the hall 9 so safety is ensured. The people then take refuge outside of a building 1 by using the elevator 7. Even if the electric system of the building main body 3 is cut off, the elevator 7 would not be stopped halfways since the electric system of the elevator 7 is provided independently of that of the building main body 3.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a building in which an elevator hall is used as a temporary evacuation room, and more specifically, the invention relates to a building in which an elevator hall is used as a temporary evacuation room. In particular, the present invention relates to a building in which an elevator hall is used as a temporary evacuation room so that evacuation can be carried out safely and reliably even in hospitals, nursing homes, etc.

(Prior Art) Conventional buildings, such as hotels, hospitals, parking lots, and other various facilities, are becoming taller and larger, and are equipped with elevators.

In such buildings, fire shutters are installed at appropriate locations in preparation for the outbreak of fire, or disaster prevention equipment such as fire alarms and emergency stairs are installed.

Further, the power source for operating the elevator is generally the same as the power source for other equipment provided in the building, and the electrical control system in the middle is commonly used.

(Problems to be Solved by the Invention) However, although fire shutters are effective in preventing the spread of fire, they not only pose a risk for people in the place where a fire occurs, but also cause them to lose the opportunity to evacuate. Other areas could not be used as evacuation sites either.

Additionally, if a fire breaks out in a building, the elevator hall, which is the most frequently used building, cannot be used as a temporary evacuation site because it is not zoned for fire protection. Furthermore, the use of elevators for evacuation in the event of a fire was prohibited.

In other words, if a fire occurs while an elevator is in use, the power supply for the elevator is the same as the building's power supply, so there is a risk that the power supply will be disconnected and the elevator may stop mid-floor or halfway between floors. You must wait for rescue at the stopped position. In particular, if the elevator stops midway between floors, rescue becomes difficult. For this reason, the use of elevators has traditionally been prohibited in the event of a fire.

In this way, even though conventional buildings are equipped with evacuation hawks, their use for evacuation in the event of a fire is prohibited;
In other cases, it was impossible to evacuate quickly and some people were left behind, resulting in serious injury.

Furthermore, when evacuating using stairs (including emergency stairs), it is dangerous if people are flooded with people, and depending on the fire situation, it may not be possible to evacuate using stairs. Particularly in high-rise hospitals, nursing homes, etc., it takes a great deal of effort to evacuate sick people on beds through the stairs.

(Purpose of the Invention) This invention was made with a focus on the above-mentioned problem, and aims to enable safe and reliable evacuation even in the event of a fire by actively utilizing elevators that are used on a daily basis. The purpose of this project is to provide a building in which the elevator hall can be used as a temporary evacuation room.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration.

That is, the building includes an elevator and an elevator hall for getting on and off the elevator, the elevator and the elevator hall are made of fire-resistant materials, and the space between the elevator hall and other rooms or passages is made of fireproof material. The elevator hall is configured as a temporary evacuation area by dividing it into a fireproof section with doors, and the electrical system for driving and controlling the elevator is provided separately from the electrical systems for the various facilities provided in the building. .

(Operation of the invention) In the above configuration, when an emergency such as a fire occurs in the building, evacuees first move from each room of the building to the elevator hall, which is a temporary evacuation site. ! make it difficult The elevator hall, along with the elevators, has a fireproof structure.
p! -fli? jl! It can be used as a difficult room. They can then evacuate the building by using the elevator in turn.

Even if the power to the building is cut off, the elevator will not stop because the elevator is powered separately.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings.

FIGS. 1 and 2 show a building according to an embodiment of the present invention, in which a building (for example, the 5th floor in this embodiment) 1 includes a building body 3 and an elevator tower 5 protruding from the building body 3. This elevator tower 5 is equipped with an elevator 7 for going up and down that connects each floor, and an elevator hall 9.9 that is open to rooms on each floor for getting on and off the elevator 7. 7 and elevator hall 9 are used on a daily basis.

Then, this elevator 7 and elevator hall 9 are
The elevator Ri5 is constructed with a fireproof floor and walls made of concrete sheet or the like, and a fire door 11 is provided between the elevator hall 9 and the building main body 3, so that the fireproof compartment can be accessed from the building main body 3. has been done. The fire door 11 is normally open, but is configured to be closed automatically or manually in the event of a fire. When the fire door 11 is closed in the event of a fire, the elevator hall 9 constitutes a temporary evacuation center, and the spread of the fire and the intrusion of smoke into the elevator hall 9 and the elevator 7 are prevented.

Therefore, the elevator hall 9 can be used as a temporary evacuation room. For this reason, it is preferable that the area of the elevator hall 9 is set to a certain extent to be large enough to be a safe area as an evacuation area, taking into consideration the situation of the floor (number of people, number and structure of other elevators, planar configuration), etc.

In the above configuration, the elevator hall 9 used as an evacuation room has a fire door that can be completely sealed and is kept at a slightly higher pressure than the outside in order to prevent smoke and toxic gases from entering from the outside. is preferable. For example, if air is supplied by a compressor, a high pressure state in the elevator hall 9 can be easily achieved.

Further, devices necessary for ensuring safety, such as a communication device and an external monitoring device, can be appropriately provided in the elevator hall 9.

Further, the electrical system of the elevator tower 5 is provided separately from the electrical systems of the various facilities provided in the main building body 3. Specifically, the elevator 7 is configured to be able to be driven and controlled even if the electrical system that drives and controls various equipment in the building body 3 is disconnected. Therefore, the illumination lights, indicator lights, etc. in the elevator hall 9 will not be out of power as well as the elevators.

Next, the effect will be explained.

In the above configuration, when an emergency such as a fire occurs in the building body 3, people in each room of the building body 3 temporarily evacuate to the Nirebane Hall 9. Since the elevator hall 9 and the elevator 7 are constructed of a fire-resistant construction, the elevator hall 9 is safe and prevents the spread of fire. Then,
It is sufficient to evacuate to the outside of the building 1 by using the elevator 7 in order. Furthermore, even if the electrical system of the building body 3 is disconnected, the elevator 7 will not stop midway since the electrical system of the elevator 7 is provided separately.

As described above, the present invention provides a safe elevator for evacuation, and as a result, it is possible to evacuate sick people along with their beds, especially in hospitals, nursing homes, etc., and as a result, early evacuation can be realized.

Therefore, the elevator 7 and elevator hall 9 used in the present invention are not separately provided for evacuation purposes and are used on a daily basis, so they can be used for evacuation operations without special evacuation training. can be done quickly and calmly.

Furthermore, since the elevator 7 is used on a daily basis, it is routinely tested for failures, making it suitable for evacuation use. Needless to say, regular maintenance and management are required.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, an emergency staircase (including an inner staircase and an outer staircase) that communicates directly with the elevator hall 9 may be provided (or an emergency staircase that is connected to the electrical system on the elevator 7 side). Evacuation lighting, smoke evacuation equipment, or evacuation display means may be provided.Such display means may include any display means, such as a display of fire prevention techniques, a display of priority order of elevator stopping floors, etc. Can be used.

Further, the elevator 7 and the elevator hall 9 may be built into the building body 3 instead of being provided in the elevator tower 5 projecting from the building body 3.

In this case, the fire protection 11 may be provided on all walls in three directions except for the elevator 711M of the elevator hall 9, or may be provided on two walls. Regarding the arrangement of the fire door 11, the vertical positions of the respective WI layers do not need to be aligned.

Furthermore, if the doors of the elevator 7 are installed in two locations, one on the elevator hall 11 side and the other on the opposite side, and the door on the opposite side of the elevator hall 9 is opened on the evacuation floor (first floor), the door on the opposite side of the elevator hall 9 can be opened. A person who gets off the elevator 7 can directly go outside without entering the building body 3 once.

In addition, on the evacuation floor, if an exit 13 leading to the outside is provided in the elevator hall 11, it is possible to go outside directly.
You can evacuate safely.

(Effects of the Invention) As explained above, according to the present invention, the elevator hall is constructed in a fireproof section with temporary evacuation.
Since the electrical system that drives and controls the elevator is provided separately from the building's electrical system, the elevator that is used daily can be used as an evacuation device. In general, an evacuation room must be a place where people who are unable to escape in the event of a fire can quickly find out its location and escape, but in this invention, the elevator hall, which is used most on a daily basis, is used as an evacuation room. , suitable as an emergency evacuation room.

In addition, the elevator can be used in the event of a fire, so
You can safely and reliably evacuate from hospitals, nursing homes, etc.
