The inside of the refuge chamber is divided into a first space (2) and a second space (3) by fire partitions (1, 4). The first space (2) communicates with the interior space of the building. The second space (3) communicates with the exterior space of the building. The fire partition (4) is provided with a fireproof door (11) connecting the first space with the second space. Any two neighboring refuge chambers are interconnected. The fire partition is provided with an observation window (12). The first space and the second space are provided with an air supply pipe (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 pipe (17). Drencher devices (9) are disposed in the first space. ## Claims ### Claim 1 A building fire escape system, comprising an auxiliary descending device, which can be used by evacuators to quickly descend from said building to evacuate if a fire takes place. ### Claim 2 (canceled) ### Claim 3 (depends on 1) A building fire escape system according to claim 1, wherein said auxiliary descending device is a sliding pole. ### Claim 4 (depends on 3) A building fire escape system according to claim 3, wherein a cushioning device is disposed at the bottom of said sliding pole; and wherein said cushioning device is a metal wire mesh affixed to a metal framework. ### Claim 5 (canceled) ### Claim 6 (depends on 3) A building fire escape system according to claim 3, wherein the upper end of said sliding pole is provided with a safety rope and a rope hook. ### Claim 7 (depends on 1) A building fire escape system according to claim 1, wherein said auxiliary descending device is a chute; wherein said chute is spiral shaped. ### Claim at position 8 8-9.
