The landing floor member bolt 213 is detachably attached to the landing floor member female thread anchor 212. The landing floor member bolt 213 is attached to the landing floor member female thread anchor 212, whereby the landing floor waterproofing member 202 is fixed to the landing floor member 105. This configuration allows the landing floor waterproofing member 202 to be fixed to the landing floor member 105 with a simple configuration.

In addition, the landing floor waterproofing member 202 is released from the landing floor member 105 by removing the landing floor member bolt 213 from the landing floor member female thread anchor 212. This configuration allows the landing floor waterproofing member 202 to be removed from the landing floor member 105 with a simple configuration.

In addition, when the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103 and the landing floor waterproofing member 202 comes into surface contact with the landing floor member 105, the landing wall waterproofing member 201, the landing floor waterproofing member 202, and the waterproof cover member 203 cover the landing operating panel 102. This configuration prevents the landing operating panel 102 from being submerged by water that has entered the landing.

Embodiment 2.
Fig. 7 is a block diagram showing an elevator shaft water-ingress prevention device according to embodiment 2.

The elevator shaft water-ingress prevention device 2 according to embodiment 2 further includes a surface contact detection device 214 that detects that the landing wall waterproofing member 201 is in surface contact with the landing wall member 103.

The detection results of the surface-contact detection device 214 are input to the elevator control panel 106. The elevator control panel 106 switches the operation mode of the elevator 1 based on the detection results of the surface-contact detection device 214. Specifically, when the surface-contact detection device 214 detects that the landing wall waterproofing member 201 is in surface contact with the landing wall member 103, the elevator control panel 106 switches the operation mode of the elevator 1 from the normal operation mode to the flood operation mode. When the operation mode of the elevator 1 is the flood operation mode, the car stops at the landing on the top floor, and the ascent and descent of the car is suspended.

The surface contact detection device 214 has a detection device main body 215 provided on the landing wall member 103, and a detectable object 216 provided on the landing wall waterproofing member 201. A detection area of the detection device main body 215 is set around the detection device main body 215. When a magnet is placed in the detection area of the detection device main body 215, the magnet is detected. The detectable object 216 is composed of a magnet. Therefore, when the detectable object 216 is present in the detection area of the detection device main body 215, the detection device main body 215 detects the detectable object 216.

When the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103, the object to be detected 216 is placed in the detection area of the detection device main body 215. Therefore, when the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103, the surface contact detection device 214 detects that the landing wall waterproofing member 201 is in surface contact with the landing wall member 103.

The other configurations of the elevator shaft flood prevention device 2 in embodiment 2 are the same as those of the elevator shaft flood prevention device 2 in embodiment 1.

As described above, the elevator shaft flood prevention device 2 according to embodiment 2 is equipped with a surface contact detection device 214. The surface contact detection device 214 detects that the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103. The detection result of the surface contact detection device 214 is input to the elevator control panel 106. With this configuration, when the elevator shaft flood prevention device 2 is installed at a landing, the operation mode of the elevator 1 can be switched from the normal operation mode to the flood operation mode.

In the second embodiment, the configuration of the surface contact detection device 214 that detects that the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103 has been described. However, the configuration is not limited to this, and the surface contact detection device 214 may be configured to detect that the landing floor waterproofing member 202 comes into surface contact with the landing floor member 105. Even with this configuration, when the elevator shaft flood prevention device 2 is installed at the landing, the operation mode of the elevator 1 can be switched from the normal operation mode to the flood operation mode. In addition, the surface contact detection device 214 may be configured to detect that the landing wall waterproofing member 201 comes into surface contact with the landing wall member 103 and that the landing floor waterproofing member 202 comes into surface contact with the landing floor member 105. In other words, the surface contact detection device 214 may be configured to detect at least one of the landing wall waterproofing member 201 coming into surface contact with the landing wall member 103 and the landing floor waterproofing member 202 coming into surface contact with the landing floor member 105.

In addition, in the first and second embodiments, the configuration in which the female thread anchor 210 for the landing wall member is arranged to extend perpendicularly to the surface of the landing wall member 103 has been described. However, as shown in FIG. 10, the female thread anchor 210 for the landing wall member may be arranged to be inclined with respect to the surface of the landing wall member 103 so as to be downward toward the back side of the landing wall member 103. In other words, the female thread anchor 210 for the landing wall member may be arranged to be inclined with respect to the surface of the landing wall member 103 so as to be downward as it moves away from the surface of the landing wall member 103 in the depth direction of the landing entrance/exit 104. According to this configuration, the landing wall waterproofing member 201 is pressed against the landing wall member 103 and the landing floor waterproofing member 202 is pressed against the landing floor member 105 by attaching the landing wall member bolt 211 to the female thread anchor 210 for the landing wall member. In this configuration, the elevator shaft flood prevention device 2 does not need to be equipped with a landing floor fixing member 209.
