<p>A negative-pressure smoke-guiding fireproof building structure comprises at least one vertical discharge flue(1) arranged in the building and a transverse discharge flue(2) arranged in the upper space of each floor. The vertical discharge flue(1) is in fluid communication with the transverse discharge flue(2). At least one natural air inlet window(4) and at least one smoke discharge window(5) are arranged in the wall(3-1) of each independent room(3) of each floor. The natural air inlet window(4) consists of an air inlet window(4-1), an air inlet window door(4-2) capable of sealing the air inlet window(4-1) in the normal state and an air inlet window door opening mechanism capable of automatically opening the air inlet window(4-1) at fire hazard. The smoke discharge window(5) consists of a smoke discharge window(5-1), a smoke discharge window door(5-2) capable of sealing the smoke discharge window(5-1) in the normal state and a smoke discharge window door(5-2) opening mechanism capable of automatically opening the smoke discharge window(5-1) at fire hazard. The smoke discharge window(5) is in fluid communication with the transverse discharge flue(2). With a simple structure, the building structure effectively prevents fire spreading to peripheral adjacent rooms when one room in the building is in fire so as to prevent larger fire hazard.</p> |
