摘要

A building fire escape system, comprising an auxiliary descent device, the auxiliary descending device being a sliding pole (6) or a spiral slide (6'), and at least one refuge chamber, the refuge chamber being a fireproof spatial structure connected to the building. The inside of the refuge chamber is divided into a first space (2) and a second space (3) by means of fireproof partitions (1, 4). The first space (2) communicates with the internal space of the building. The second space (3) is connected to the external space of the building. The fire partition (4) is provided with a fireproof door (11) connecting the first space and the second space. Any two neighboring refuge chambers are connected. The fire partition is provided with an observation window (12). The first space and the second space are provided with an air supply conduit (14) and an air exhaust pipe (15). Disposed at the top of the refuge chamber is a water tank (16) connected to the fire main (17). Sprinkler devices (9) are disposed in the first space.
