EXTINGUISHING SYSTEM FOR MULTISTORY BUILDING OR BUILDING STRUCTURE Russian patent published in 2006 - IPC A62C35/58 

FIELD: fire-fighting, particularly to extinguish multistory buildings.

SUBSTANCE: system comprises sealed vessel for fire-extinguishing composition storage under pressure, fire-extinguishing composition supply pipelines, which are adapted to feed fire-extinguishing composition into objects to be protected and vessel pressure maintaining means. The vessel is made as a number of tubular accumulation high-pressure tanks connected with each other and arranged preferably along vertical and horizontal building axes along the full height of building stories provided with rooms to be protected. Connection devices between tubular accumulation high-pressure tanks are made as connection tubular high-pressure tanks. Fire-extinguishing composition supply pipelines, which deliver fire-extinguishing composition into object to be protected, are connected to fire-extinguishing composition storage vessel through valves. Fire-extinguishing system is provided with refilling means to compensate fire-extinguishing composition losses. The refilling means is connected to the vessel. Accumulation and connection tubular tanks may be made as a part of load-bearing building frame. Accumulation and connection tank diameters may not exceed 150 mm. Fire-extinguishing composition storage vessel capacity provides double fire-extinguishment operation in room to be protected having maximal possible volume.

EFFECT: increased efficiency of multistory building extinguishment, improved operational reliability and simplified operation.
