High rise building with a stairwell and a intake air shaft

1. A high-rise building, comprising:

a plurality of stories having a height of the building;

a stairwell;

an air supply shaft extending over the entire height of the building;

inlet openings connecting the air supply shaft to the stairwell; and

a pressure system for keeping the stairwell free from smoke,

wherein the stairwell is vertically divided into partial spaces by at least one partition, each partial space extends over multiple of said stories, each partition comprises at least one pressure flap and a door, and the door enables a passage from one partial space of the stairwell into an adjacent partial space,

at least one of (i) each partial space has a number of said inlet openings that is less than the number of said multiple stories over which said partial space extends, (ii) at least two adjacent stories of the same partial space are connectable to the air supply shaft by only one of said inlet openings, and (iii) at least one story of each partial space does not include an inlet opening, and

at least one inlet opening within each partial space provides air to those of said stories within that partial space that does not include an inlet opening,

wherein the air supply shaft is connected to each of the partial spaces via at least one of the inlet openings that have a valve allocated thereto,

wherein the building comprises a fire alarm system and a control unit, the control unit is operatively connected to the fire alarm system, and in case of a source of fire located in one of the stories, the control unit controls air flows through the inlet openings and supplies with air only said partial space of the stairwell that corresponds to the location of the source of the fire, and wherein the valve controls said flow of air passing through the inlet openings and is operatively connected to the control unit therefore, and

wherein information is stored in the control unit as to which of the stories of the building are associated with which of the partial spaces of the stairwell.

2. A high-rise building according to claim 1 , wherein the partial spaces extend over ten to thirty stories.

3. A high-rise building according to claim 1 , wherein the at least one pressure flap is a barometric pressure flap.

4. A high-rise building according to claim 1 , wherein the partition comprises two pressure flaps disposed in different flow directions.

5. A high-rise building according to claim 1 , wherein the door opens in an escape direction.

6. A high-rise building according to claim 1 , wherein the door is normally in an opened position, and, only in case of a fire alarm, the door is moved into one of a partially closed position and a closed position.

7. A high-rise building according to claim 1 , wherein the partition is normally incomplete, and mechanically completed in response to a fire alarm.

8. A high-rise building according to claim 1 , further including a fire alarm system, wherein the fire alarm system comprises a plurality of fire detectors and is configured such that a story of the building in which a case of fire occurs can be determined.

9. A high-rise building according to claim 1 , wherein the door is one of a hinged door and a swinging door.

10. A high-rise building according to claim 1 , wherein the partial spaces extend over fifteen to twenty stories.

11. A high-rise building according to claim 1 , wherein the partition normally does not completely separate adjacent partial spaces, and in case of a fire alarm, the partition is configured to completely separate said adjacent partial spaces.

12. The high-rise building according to claim 1 , wherein the partition comprises two pressure flaps that allow air to flow in different directions.
