A negative-pressure smoke-guiding fireproof building structure includes at least one vertical smoke discharge flue (1) arranged in the building and a transverse smoke discharge flue (2) arranged in upper space of each floor. The vertical smoke discharge flue (1) is in fluid communication with the transverse smoke discharge flue (2). At least one natural air inlet window (4) and at least one smoke-gas discharge window (5) are arranged in a 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 a fire hazard. The smoke-gas 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 opening mechanism capable of automatically opening the smoke discharge window (5-1) at a fire hazard. The smoke-gas discharge window (5) is in fluid communication with the transverse smoke discharge flue (2). With a simple structure, the building structure effectively prevents fire spreading to peripheral adjacent rooms when one room in the building catches fire, so as to prevent a larger fire hazard. |
