Document Type and Number:
WIPO Patent Application WO/2022/055041
Kind Code:
A1
Abstract:
The present invention relates to the structure of an air-supplying/pressurizing/smoke-controlling equipment for a high-rise building stairwell, the equipment comprising: a flap damper (10) installed in a stairwell (4) of a high-rise building (1) so as to discharge air in the stairwell (4) to the outside by being automatically opened when pressure in the stairwell (4) is equal to or higher than a predetermine pressure; an air-supplying unit (20) for automatically supplying outside air to a specific floor of the stairwell (4) in the event of a fire; and an air curtain unit (30) installed at each of entrances of the stairwell (4) so as to automatically operate at the time of opening of an entrance door to reduce the cross-sectional area of an entrance door outflow air current. The present invention is advantageous in that smoke generated in a living room on fire can be restrained from moving into the stairwell by reducing a chimney effect in the event of a fire, and thus residents can safely evacuate and take refuge through the stairwell in the event of a fire, and a fire-fighting team can easily enter to easily extinguish a fire, whereby casualties and property damage due to the outbreak of the fire can be reduced.
