Description

{A fire escape for an emergency staircase}

The present invention relates to an emergency stair fire evacuation device that allows the evacuation of a building to move to a safe area quickly and safely in case of an emergency due to a fire of a high or low rise building. In case of occurrence, the emergency staircase used by the evacuees is installed with a mobile passage configured to receive fresh air while the evacuators are safely moved from flames and harmful gases. The present invention relates to a fire escape apparatus for emergency stairs provided with an intake duct to prevent the evacuator from being exposed to flames and harmful gases.

Typically, high-rise or low-rise buildings are equipped with fire-fighting equipment to extinguish the fire in the event of a fire.

 It is installed for the purpose of extinguishing a fire in a building, and evacuators in a building are installed to move quickly to a safe place on a rooftop or lower floor of a non-flame building. Generally, in various mass media, high heat and flame progress during a fire. I do not use an elevator that can not grasp the situation and imprint it to use emergency stairs.

In the event of a fire, bulldozers in the building must use the emergency stairs quickly through the exit.

At this time, there is a need for a device to protect the evacuator who is trying to use the emergency stairway from the flame or toxic gas generated in the fire of the building, such a conventional device is disclosed in Utility Model Publication No. 20-2007-0001065 It is disclosed in the method of the smoke control using the and the device name.

Looking at the prior art disclosed in the accompanying drawings Figure 1 as follows.

It has an outdoor air inlet 61 for air supply on the rooftop or the ground, and has a vertical air supply duct 12 and a horizontal air supply duct 12-1 inside the building, and an accessory room 32 is provided on each floor of a high-rise building. The air cut device 41 connected to the horizontal air supply duct 12-1 is installed in the upper part of the inside door of the accessory compartment. When the air curtain device 41 operates in the event of fire, the fresh air blown out from the outside air inlet 61 is installed. Air is discharged to the air curtain device discharge port through the vertical air supply duct 12 and the horizontal air supply duct 12-1. The air curtain is formed by the discharge pressure of the discharged air. A fuming method for high-rise buildings, such as apartments and business buildings, characterized in that the smoke is directly prevented from entering the ancillary room 32;

Remove the air supply blower installed on the rooftop or rooftop and basement floor, and replace the air supply opening 61, the vertical air supply duct 12 and the horizontal air supply duct 12-1 at the boundary of the smoke control area (upper side of the access door) among the smoke control areas of each floor. It is disclosed as a smoke control device characterized in that the air curtain device 41 is connected to the installation, it can be seen that the installed air curtain to prevent the toxic gas generated in the building interior from entering the auxiliary room or emergency stairs.

However, the problem of the prior art as described above

First, when a fire occurs, it is difficult to supply power to the air curtain device installed on each floor due to the power off.

Second, if a fire occurs in the air curtain device due to the explosion that can occur during the fire, it is difficult to use the emergency stairs of the floor.

Third, many evacuees have to be installed in a narrow and wide area to pass through doors to annex or emergency stairs, which consumes huge operating costs.

Fourth, it is difficult for the elderly, pregnant women and the disabled to open and pass through the weight chain fire door installed in the front of the air curtain device.

Fifth, the strong wind coming from the air curtain equipment has a problem that increases the flame to increase the flame.

The present invention has been made to solve the above-mentioned problems, and in an emergency such as a fire in a building to evacuate to the roof or lower floor of the building safely through the mobile passage, and also fresh air outside the building flowed into the mobile passage The air is discharged to the emergency staircase so that there is no difficulty in evacuation of the evacuator.
