  Each elevator car 5 has a first car doorway 5a and a second car doorway 5b opposite to the first car doorway 5a. That is, the first and second car entrances 5 a and 5 b are arranged before and after the elevator car 5. Each first car doorway 5a is opened and closed by a first car door device 6 including a first car door. Each second car doorway 5b is opened and closed by a second car door device 7 including a second car door.

  On the elevator stop floor, a normal elevator hall (getting on / off lobby) 8, corridor 9, living room 10, ancillary room 11, and special escape staircase room 12 are provided. A room entrance door 13 is provided between the hallway 9 and the room 10. An auxiliary room fire door 14 is provided between the corridor 9 and the auxiliary room 11. A staircase fire door 15 is provided between the ancillary room 11 and the special escape staircase room 12. In some cases, a fire door with a hollow door is provided between the elevator hall 8 and the corridor 9.

  Thereby, the ancillary room 11 is a fire prevention section different from the elevator hall 8, the corridor 9, the living room 10, and the special escape staircase room 12. The special evacuation staircase room 12 is a fire prevention section different from the elevator hall 8, the hallway 9, the living room 10, and the ancillary room 11. The elevator hall 8, the living room 10, the auxiliary room 11, and the special evacuation staircase room 12 are provided with fire detectors 16 to 19 that detect fire independently.

  The elevator hall 8 is provided with two normal hall entrances 20 which are first hall entrances corresponding to the first car entrance 5a. Each normal landing doorway 20 is opened and closed by a normal landing door device 21 including a normal landing door.

  The ancillary room 11 is provided with an ancillary hall entrance / exit 22 that is a second entrance / exit corresponding to the second car entrance / exit 5b of the elevator car 5 of Unit A. The ancillary hall entrance / exit 22 is opened and closed by an ancillary hall landing door device 23 including an ancillary hall landing door.

  The special evacuation staircase room 12 is provided with a staircase hall entrance / exit 24 that is a second landing entrance corresponding to the second car entrance 5b of the elevator car 5 of Unit B. The staircase hall entrance / exit 24 is opened and closed by a staircase hall door device 25 including a staircase hall door.

  The normal landing door device 21 is opened and closed in conjunction with the first car door device 6. The ancillary hall door device 23 and the staircase hall door device 25 are opened and closed in conjunction with the second car door device 7.

  As described above, the normal hall entrance / exit 20, the ancillary hall entrance / exit 22 and the staircase hall entrance / exit 24 are provided in different fire prevention sections. In addition, the fire prevention section in which the normal hall entrance / exit 20 is provided, the fire prevention section in which the ancillary hall entrance / exit 22 is provided, and the fire prevention section in which the staircase hall entrance / exit 24 are provided are separately provided for fire detection. Containers 16, 18, and 19 are provided.

  FIG. 2 is a block diagram showing the control system for the building with an elevator shown in FIG. Each elevator is controlled by a corresponding elevator control device 31. Further, the elevator control device 31 of the elevators included in the common elevator group is comprehensively controlled by the elevator group management device 32. The fire detectors 16 to 19 are connected to the disaster prevention management device 33. That is, the disaster prevention management device 33 monitors the states of all the fire detectors 16 to 19 in the building.

  The elevator group management device 32 and the disaster prevention management device 33 are connected to an evacuation operation control device 34 as an open / close management unit. The evacuation operation control device 34 receives the fire occurrence information from the disaster prevention management device 33 and instructs the elevator group management device 32 to perform a fire control operation. Moreover, the evacuation operation control apparatus 34 commands the evacuation operation to the elevator group management apparatus 32 after the end of the fire control operation.

  FIG. 3 is a flowchart showing the operation of the evacuation operation control device 34 of FIG. When a fire is detected by at least one of the fire detectors 16 to 19 and the occurrence of the fire is confirmed by the disaster prevention management device 33, the fire occurrence confirmation information is input to the evacuation operation control device 34. Thereby, the evacuation operation control device 34 first outputs a command to perform the fire control operation to the elevator group management device 32 (step S1). In the fire control operation, all the traveling elevator cars 5 are stopped at a predetermined return floor, and then opened, and passengers in the elevator cars 5 get off.

  Next, the evacuation operation control device 34 determines whether or not to perform an evacuation operation by an elevator (step S2). If the evacuation operation cannot be performed, the process ends. If the evacuation operation can be performed, the evacuation operation control device 34 formulates an evacuation operation method and outputs an evacuation operation command to the elevator group management device 32 (step S3).

  Here, although various methods can be considered as the evacuation operation method, the same operation method as a normal automatic operation is mentioned as an example. In this method, when a landing call is registered by a passenger pressing a landing button at the landing, an appropriate elevator car 5 is assigned by the elevator group management device 32 and responds. Then, a passenger moves to an evacuation floor (for example, entrance floor) by an elevator and escapes from the building. According to this evacuation operation method, passengers are not confused about how to use the elevator.

  Further, as another evacuation operation method, there is a method in which a rescue floor where the elevator car 5 can be boarded is set and the elevator car 5 is reciprocated only between the rescue floor and the evacuation floor. In this method, the passenger moves to the rescue floor by the stairs and moves from the rescue floor to the evacuation floor by the elevator. According to this evacuation operation method, the operation efficiency of the elevator is high, and it can be expected that the time until the evacuation is completed is shortened. However, in this method, since the operation is different from the normal operation, it is desirable to perform guidance guidance using an emergency broadcast device or a display device.

  Although the evacuation operation method can be considered in addition to the above, an appropriate method can be planned and set in advance in the evacuation operation control device 34 depending on the shape of the building, the application, the population in the hall, and the like.

  As described above, when the evacuation operation is performed and the evacuation of the person in the building advances, there is no passenger who desires to use the elevator. Therefore, the evacuation operation control device 34 repeatedly determines whether or not to end the evacuation operation during the evacuation operation (step S4). For example, it is determined that the evacuation operation is to be terminated when no passengers are detected for a predetermined time on the floor where passengers to be evacuated are to be boarded in the elevator car 5 or when no hall call is detected. When ending the evacuation operation, the evacuation operation control device 34 outputs a command to end the evacuation operation to the elevator group management device 32 and ends the process (step S5).

  Here, the evacuation operation control device 34 manages permission / prohibition of opening / closing of the first car doorway 5a and opening / closing of the second car doorway 5b. In this example, the evacuation operation control device 34 normally permits the opening and closing of the first car doorway 5a and prohibits the opening and closing of the second car doorway 5b. Further, the evacuation operation control device 34 prohibits the opening and closing of the first car doorway 5a and permits the opening and closing of the second car doorway 5b in the event of a fire.

  The evacuation operation control device 34 has a computer. That is, the function of the evacuation operation control device 34 can be realized by a calculation process by a computer.

  In such a building with an elevator, it is possible to get on and off the elevator car 5 from different fire prevention zones, so that a passenger can be put on the elevator car 5 from a safer point in the event of a fire.

  In addition, the normal hall entrance / exit 20 is provided in the normal elevator hall, and the ancillary hall entrance / exit 22 and the staircase hall entrance / exit 24 are provided in the ancillary room 11 and the special evacuation staircase room 12, respectively. By combining evacuation and evacuation by an elevator, the elevator can perform more efficient evacuation operation.

  Furthermore, fire detectors 16 for detecting fire independently are provided in the fire prevention compartment provided with the normal hall entrance / exit 20 and the fire prevention compartment provided with the auxiliary hall entrance / exit 22 and the staircase hall entrance / exit 24, respectively. Since 18 and 19 are provided, a passenger can be put on the elevator car 5 from a safer point.

  Furthermore, since the evacuation operation control device 34 automatically permits the opening and closing of the car entrances 5a and 5b which are different between normal times and fires, the boarding point of the elevator car 5 is made a safer point when a fire occurs. Can be switched quickly.

Embodiment 2. FIG.
Next, FIG. 4 is a block diagram showing a building with an elevator according to Embodiment 2 of the present invention, and the planar layout of each floor is the same as FIG. In this example, the elevator control device 31 and the elevator group management device 32 are installed in an elevator machine room 35 provided above the hoistways 2 and 3. The disaster prevention management device 33 is installed in a disaster prevention center 36 that is separated from the elevator machine room 35. Further, the evacuation operation control device 34 is provided in an elevator monitoring panel 37 installed in the disaster prevention center 36.

  The disaster prevention management device 33 and the elevator monitoring panel 37 are monitored and operated by the disaster prevention center personnel. Whether the evacuation operation control device 34 of the elevator monitoring panel 37 permits the opening / closing of the first car entrance / exit 5a and the opening / closing of the second car entrance / exit 5b depending on the situation of the fire. Can be entered. Other configurations are the same as those in the first embodiment.

  The disaster prevention center staff sets a service cut method by the elevator monitoring panel 37 according to the fire progress situation obtained from the display contents of the disaster prevention management device 33. For example, during normal times, the opening and closing of the second car entrance 5b is prohibited on all floors. Thus, of course, opening and closing of the ancillary hall entrance / exit 22 and the staircase hall entrance / exit 24 are also prohibited.

  In addition, immediately after the occurrence of a fire, if the elevator hall 8, the attached room 11 and the attached room 11 on all floors are not contaminated with heat or smoke, no fire is detected by all of the fire detectors 16, 18, and 19. After confirming this with the disaster prevention management apparatus 33, the service cut of all the entrances is cancelled | released. Thereby, boarding / alighting with respect to the elevator car 5 becomes possible using both the first and second car entrances 5a and 5b.

  Further, when the fire progresses and the elevator hall 8 on the fire floor is contaminated, the fire prevention device 16 of the elevator hall 8 on the fire floor confirms that the fire is detected by the disaster prevention management device 33. The opening and closing of the first car doorway 5a is prohibited. Therefore, after this, it is possible to get on and off the elevator car 5 using only the second car entrance 5b.

  Furthermore, when the ancillary room 11 on the fire floor is contaminated with smoke, the fire prevention device 18 of the ancillary room 11 on the fire floor confirms that the fire is detected by the disaster prevention management device 33, and then The opening and closing of the second car entrance 5b of the elevator car 5 is prohibited. Therefore, after this, on this floor, it is possible to get on and off the elevator car 5 using only the second doorway 5b of the elevator car 5 of the Unit B. The service cut procedure as described above is merely an example, and various settings can be made according to the fire situation.

  In such a building with an elevator, it is possible to input to the evacuation operation control device 34 whether to permit the opening and closing of the first car doorway 5a and whether to permit the opening and closing of the second car doorway 5b during a fire. Therefore, service cuts can be added / released depending on the fire situation, passengers can be put in the elevator car 5 from a safer point, and evacuation by the elevator can be utilized to the maximum .

In the above example, a building in which two elevators are installed is shown, but one or three or more may be used.
Further, in the above example, two car doorways are provided in one elevator car, but three or more car doorways may be provided.
Furthermore, the fire prevention section in which the second landing entrance is provided is not limited to the special escape staircase attached room and the special escape staircase room.
Furthermore, in the above example, the car entrances 5a and 5b are provided before and after the elevator car 5. However, the present invention is not limited to this. For example, the first and second parts are provided on the front surface of the car and the side surface perpendicular thereto. A car doorway may be provided. Also in this case, of course, the first and second landing entrances are provided in different fire prevention sections.
