Description

[0001] The present invention relates to a ventilation system using emergency stairs of a multi-story building,

The present invention relates to a ventilation system using an emergency stairway of a multi-story building. More particularly, the present invention relates to a ventilation system using an emergency staircase. More particularly, The present invention relates to a ventilation system using an emergency stairway of a multi-story building, in which gas and smoke generated in an indoor area of a multi-story building are prevented from entering into an emergency stairway so that large piles can be safely evacuated without difficulty in breathing.

Typically, multi-storey buildings are equipped with fire fighting equipment to extinguish the fire when a fire occurs.

It is installed for the purpose of suppressing the building fire. The big pizza in the building is installed to move quickly to the safety zone on the roof or the lower floor of the fireless building. Generally, in various media, I do not use an elevator that I can not grasp.

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

On the other hand, in general, large-sized buildings such as high-rise apartment buildings and buildings cause large-scale casualties in case of fire.

Such smoke has a relatively low risk of personal injury rather than a flame condition and toxic gas immediately after combustion, but the main factor causing smoke damage in the event of a fire is a duct inside the building, Because of the rapid spread of the area to the evacuation area as well as the area, it is difficult to evacuate quickly through the evacuation area such as emergency stairs.

Conventional emergency stairs have a system in which a ventilation window is formed at the top of a natural ventilation system, and air in an emergency staircase is discharged to the outside through natural ventilation.

Therefore, if a fire occurs, hot fire and smoke will flow into the emergency staircase naturally as the air flows and spread to the upper part. If a fire occurs in the 6th floor, But it is difficult to escape to the emergency stairway due to the smoke and fire that flow in.

Meanwhile, in order to solve such a problem, in the Utility Model No. 20-2007-0001065, a method called " a ventilation method using an air curtain device and its device " is disclosed.

Referring to FIG. 1, the air conditioner includes a supply air inlet 61 on the roof or ground, a vertical supply duct 12 and a horizontal supply duct 12-1 on the inside of the building, And an air curtain device 41 connected to the horizontal air supply duct 12-1 is provided at the boundary of the smoke inlet area (inner upper portion of the entrance room door). When the air curtain device 41 is activated during a fire, Fresh air blown from the outside is blown out through the vertical air supply duct 12 and the horizontal air supply duct 12-1 to the air curtain device discharge port. At this time, the air curtain (air film) formed by the discharge pressure of the discharged air, And the smoke generated in the living room or hallway of the floor is directly blocked from entering the auxiliary room 32. [

That is, the air curtain device 41 connected to the outside air intake port 61, the vertical air supply duct 12, and the horizontal air supply duct 12-1 is provided at the boundary of the smoke chamber of each floor And it is known that an air curtain is installed to prevent the toxic gas generated in the inside of the building from flowing into the subsidiary room or the emergency staircase.

However, in the above-mentioned conventional technology, when the fire occurs, it is difficult to supply power to the air curtain device installed on each floor due to the cutoff of the power source, and when a fire occurs in the air curtain device due to an explosion that may occur during a fire, The emergency stairs of the floor cause problems that are difficult to use.

In addition, many escapees are required to be installed narrowly and broadly in order to pass through the door or the emergency stairs. However, there is a problem in that a large operating cost is incurred, and the strong wind from the air curtain device increases the flame, There is a problem that it becomes large.

Therefore, it is possible to easily install and repair the air conditioner because the separate ventilation unit for each floor is not connected to the air conditioner, so that the air current can flow from the upper part to the lower part of the multi- A ventilation system using an emergency stairway is required.
