Problems solved by technology

[0004] However, if the rescue operation continues until the elevator hall is contaminated by flames or smoke, for example due to flames and water used in conjunction with fire-fighting activities, etc., there is an increased possibility of sudden failure of the elevator during the rescue operation
Therefore, in order to prevent the rescue operation from being stopped due to a failure (abnormality) of the elevator, it is necessary to implement various measures against fire prevention, smoke prevention, and waterproofing for the elevator, resulting in an increase in cost

Embodiment approach 1

[0016] figure 1 It is a block diagram showing a fire evacuation support system according to Embodiment 1 of the present invention. and, figure 2 Yes means there is figure 1 Floor plan of the building with the elevator shown. In the figure, a plurality of elevator groups 2 are provided in a building 1 . Each elevator group 2 has a plurality of elevators 3 .

[0017] On each floor of the building 1, a common hall (elevator hall) where each elevator 3 is installed and a passage adjacent to the hall are provided. The landing is used as the elevator installation area 4 . The passageway is divided into an adjacent area 5 adjacent to the elevator setting area 4, and two outer areas 6 and 7 ( figure 2 ).

[0018] The adjacent area 5 communicates with the elevator installation area 4 through the first communication port 8 . Between the elevator installation area 4 and the adjacent area 5, the 1st fire door 9 which opens and closes the 1st communication port 8 is provided. Ea...

Abstract

Each floor of a building has an elevator installation zone where an elevator is provided, an adjacent zone adjacent to the elevator installation zone and communicated with the elevator installation zone through a first communication opening, and an external zone communicated with the adjacent zone through a second communication opening different from the first communication opening. The first communication opening is opened and closed by a first fire door, and the second communication opening is opened and closed by a second fire door. If a fire occurs in the building, a fire evacuation support system controls operation of the elevator based on information from fire detectors provided in each floor. Also, the fire evacuation support system has an evacuation operation command section. The evacuation operation command section enables the elevator to perform evacuation operation by which persons left in the building are transported to an evacuation floor when effects by the fire in both the elevator installation zone and the adjacent zone are prevented, and the evacuation operation command section stops the execution of the evacuation operation when at least either of the elevator installation zone and the adjacent zone has effects of the fire.

Description

technical field [0001] The present invention relates to a fire evacuation support system and a fire door control device for evacuating people remaining in a building when a fire breaks out in the building. Background technique [0002] Conventionally, there has been proposed a fire control operation system for elevators that rescues people remaining in the building to an evacuation floor when a fire detector installed in the building operates. In the conventional elevator fire control operation system, based on the information from the fire detector, the evacuation time for fire or smoke reaching the elevator hall is predicted and calculated, and the elevator rescue operation for rescuing the remaining personnel is carried out within the range of the predicted evacuation time. Therefore, the elevator rescue operation may be performed until fire or smoke reaches the elevator hall (refer to Patent Document 1).
