Can I buy the floor of the fire corridor?
1, floor advantages of the fire corridor: the middle apartment facing north of the fire corridor can maximize lighting and ventilation. There is generally no concave-convex shape on the south side of a building with a fire corridor, so the windows and balconies on the south side can avoid blocking each other. The floor itself is designed for the personal safety of residents, so that in case of fire, firefighters can put out the fire and residents can escape.
2. Disadvantages of the floor of the fire corridor: the corridor is close to the middle apartment. If the other two households walk in the corridor, it is easy to see the owner's house in the middle apartment through the window. If the railing of the corridor is not high enough, it is easy for children to climb it when playing, which is more dangerous. The pool area is large, which increases the cost of the head of household.
Why should high-rise buildings design corridors?
High-rise corridors are more and more common. Besides being used for lighting and ventilation of intermediate residents, its real purpose is to meet the requirements of fire prevention in high-rise buildings.
The high-rise corridor itself does not need to leave under normal circumstances. The corridor exists to meet the "two evacuation exits" (stairs) of high-rise buildings.
On both sides of the corridor are two units, each with an elevator and stairs. The door leading to the corridor is a normally closed fire door (automatically closed, but not locked).
When there is a fire, people can't take the elevator or escape from the stairs, but the downstairs of their own unit is on fire, so the stairs of this unit may be impassable. At this time, people above the fire floor enter the stairs of the next unit through the corridor to escape.
