Structure for supplying water to same layer by different alarm valve banks in super high-rise building

Abstract

The invention belongs to the technical field of automatic water spraying and fire extinguishing system design in building fire fighting, and provides a structure for supplying water to the same layerby different alarm valve banks in a super high-rise building. The technical scheme adopted by the invention is that a first automatic water spraying and fire extinguishing system is used for supplyingwater to first water spraying pipeline systems of corresponding floors through first water distribution pipes of different floors from a first alarm valve bank along the water flowing direction afterbeing shunt through a first water distribution main pipe; a second automatic water spraying and fire extinguishing system is used for supplying water to second water spraying pipeline systems of corresponding floors through second water distribution pipes of different floors from a second alarm valve bank along the water flowing direction after being shunt through a second water distribution mainpipe; and on all floors, the first water distribution pipes, the first water spraying pipeline systems, the second water distribution pipes and the second water spraying pipeline systems are arranged. The problem of risk control of alarm valve banks and water distribution main pipes is solved, the structure that water is supplied to the water spraying pipeline systems on the same layer in the super high-rise building by the water distribution pipes of different alarm valve banks is benefited, and the reliability of the whole automatic water spraying and fire extinguishing system is favorablyimproved.

Description

technical field [0001] The invention belongs to the technical field of automatic sprinkler system design in building fire protection, and particularly relates to the water supply structure of alarm valve groups in super high-rise buildings. Background technique [0002] Automatic sprinkler system is an effective and economical water fire extinguishing system, which has been widely recognized and used in building fire protection design. From industrial buildings to civil buildings, from residential buildings to various public buildings, the fire extinguishing effect of automatic sprinkler systems has gradually been reflected. How to further improve the reliability of automatic sprinkler system is particularly important. [0003] In the traditional sprinkler system design, the floor area of ​​super high-rise buildings is limited, and a single alarm valve group supplies water from the main water distribution pipe through the water distribution pipe to the sprinkler piping syst...
