Abstract

[Problem] When a major disaster occurs, rescuers from the fire department can use a cleaning gondola, ladder truck, or helicopter to rescue people, but rescue is difficult and time-consuming due to rain or strong winds. Depending on road conditions, ladder trucks may be delayed and there is a limit to the number of ladder trucks available. In high-rise buildings, carrying a tanker down the stairs limits the physical strength and number of rescuers. To provide rescue equipment to be installed inside a building to quickly rescue people from high-rise buildings.
[Solution] By installing rescue equipment inside the building, rescue can be carried out regardless of rain or strong winds. We propose that by creating vertical holes (vertical holes) about 20m deep inside the building, one after the other, fire rescuers can carry out rescue using a tanker and rope. With daily training, rescue is possible at a height of about 20m with little wear and tear, and the vertical holes have ladders attached so that people can descend to the bottom.

Description

When a major disaster occurs and the elevators become unusable due to a loss of power, the current situation is that there are no facilities in place for fire rescue teams to evacuate people from buildings.

When a major disaster occurs, rescuers from the fire department can use cleaning gondolas, ladder trucks, or ledges to carry out rescue operations, but rescue operations are difficult and time-consuming in rain or strong winds. Depending on road conditions, ladder trucks may be delayed, and there is a limit to the number of vehicles available.
Carrying a tanker down the stairs of a high-rise building places limitations on physical strength and the number of people that can be rescued.

By installing rescue equipment inside the building, rescue can be carried out without being affected by rain or strong winds.
We propose that by creating vertical holes (vertical cavity holes) about 20m deep alternating downwards inside the building, fire rescue crews would be able to carry out rescue operations using tankers and ropes.
Through daily training, rescue is possible with minimal wear and tear at heights of around 20m. This vertical cavity has a ladder that allows people to descend to the bottom.

If several fire rescuers arrive, they can use tankers and ropes to rescue many people without having to move up and down.

A vertical hole (hollow cavity) 1 is installed in the building, and a fishing hook 4 is installed on the ceiling above this vertical hole 1. A dedicated fishing hook 7 is attached to this fishing hook 4, and a tanker 9 is attached to a rope coming out of the dedicated fishing hook 7, and a rescuer 10 on the tanker 9 is lowered. A ladder 3 is attached to this hollow cavity 1, allowing people to descend to the bottom.

External view By creating vertical holes (vertical hole cavities) 1 inside the building, one after the other, tankers can be lowered in several batches. A fishing hook 4 is installed above the vertical holes (vertical hole cavities) 1 (on the ceiling).

Dedicated fishing equipment

The rope 5 is wound around the shaft 12 of the special fishing fitting 7, and the blocks 14 and 15 are joined together and secured with a set screw 16 to store the rope. A weak leaf spring 17 is attached to prevent the rope 5 from getting tangled inside the special fitting 7.
Rope storage block

A rope 5 is wound around the shaft 12 and used in conjunction with rope storage blocks 15 and 14.
Dimension A is for 3 ropes, and dimension B is for 10 ropes. If the space is too narrow, the winding shape of the rope 5 inside the special fitting 7 may change. Dimension C is 15 cm long to prevent the rope from getting tangled inside the fitting, and the hole for the rope to enter and exit is as small as possible, and is prevented by a weak leaf spring 17.

How to tie a rope This explains how to tie a rope 5 to the shaft 12. The thickness of the shaft 12 needs to be changed according to the rope.

Rope explanation: In Figure E, connect the carabiner with the loop on rope 5A to the tanker fitting, then operate rope 5B to lower the tanker. Once the tanker has been lowered, pull rope 5A until it reaches the position of rope 5D in Figure F. Lightly press rope 5C and pull rope 5D. When rope wound position 18 moves to rope wound position 19, and the carabiner with the loop on rope 5D is connected to the tanker of the next person to be rescued, the next person can be lowered with this special fishing fitting, which eliminates the need to rewind the rope.

It is necessary to install them when constructing a new building. Because it involves human life, it may be difficult for ordinary people to use it, but if there is a helper and they train, they can use the ladder to climb down by attaching a rope with a special metal fitting as a lifeline.
If fire doors are installed in vertical holes (vertical cavities) in a building, their utility value increases.

It is not affected by the weather, it is less physically demanding for fire rescuers and there is no danger, so it can be used in various ways and you can also descend using a ladder.
