FIRE BUILDING BLOCK, METHOD FOR BUILDING BLOCK PRODUCTION AND FIRE-PROOFING WALL STRUCTURE TO BE CONSTRUCTED OF SAID BLOCKS Russian patent published in 2007 - IPC E04C1/40 

FIELD: construction, particularly all-purpose buildings, namely structures to prevent fire and combustion product spread from burning room or fire site compartment to other rooms.

SUBSTANCE: fire building block comprises outer layers of fine concrete and heat-insulation core layer of light-weight porous concrete. Outer layers define closed shell enclosing the core layer. Pipes with three-way valves are inserted through outer layer to communicate core layer with vacuum-compression and water pipelines. Temperature sensor is installed on outer surface of outer layer. The temperature sensor sends signals to each three-way valve to lock one pipe and to communicate core layer with vacuum-compression pipeline through another pipe to evacuate air therefrom to increase heat transfer resistance. As fire occurs pipe is brought into communication with water pipeline to fill core layer with water for building block cooling. After fire liquidation pipe is communicated with vacuum-compression pipeline for core layer drying. Method for fire building block production and fire-proofing wall structure erection are also disclosed.

EFFECT: increased fire protection.
