SYSTEM FOR FIRE PROTECTION OF BUILDINGS Russian patent published in 2018 - IPC E04B1/76 E04B1/94 

FIELD: fire safety.

SUBSTANCE: system for fire protection structures includes outer walls at least partially covered by insulating plates made of the combustible thermoplastic insulating material, in particular, rigid foam blocks made of polystyrene, polyurethane and the like which are attached to the wall construction by gluing and/or anchoring. The coating is interrupted by at least one preferably continuous or circular layer of fire retardant beams and/or contains a fire barrier above each hole. Fire retardant beams are formed from materials that are non-flammable and/or retain their shape stability when exposed to heat and form a barrier between the upper and lower layers of heat-insulating panels (4-6) against flame propagation in the event of a fire. Thermal insulation plates made of a thermoplastic thermal insulation material are located above and/or below the fire retardant beams, and the upper side (9) of the fire retardant beam (3) oriented towards the overlying layer of heat-insulating plates (5) is perpendicular to the front side (8') of the fireproof of the beam (3) and/or has a bevelled surface (9) that is inclined downwardly towards the exterior wall (1) of the building, and this top side (9, 9') is covered with a flame retardant agent.

EFFECT: invention makes it possible to reduce the spread of flame over an open coating.
