FIELD: fire safety.
SUBSTANCE: system for fire protection structures includes outer walls at least partially covered by insulating plates made of 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. Coating is interrupted by at least one or preferably a continuous circular grate layer and/or comprises a hole over each grate. Grates are made of materials which are non-flammable and/or retain its shape under heat, in particular of gas-filled materials such as PUR, PIR, EPS coated silicate and the like, and is formed between the upper layer and the lower insulation board ( 4-6) barrier against flame propagation in case of fire. Insulation plate made of a thermoplastic insulating material, arranged above and/or below the fire bars, the coating is prepared for application of stuccowork. The surface (9) of the grate (3), oriented to the overlying layer of insulation boards (5) has an inclined surface (9) inclined downwards to the outer wall (1) of the construction. The upper front side (9) and the front side 8' of the grate, facing away from the wall structure, it is clean, that is free of coatings, so that the front side of the grate itself is accessible for applying stuccowork.
EFFECT: invention improves the efficiency of the fire protection foreside of the constructions, formed from insulation board, in particular made of thermoplastic insulating material.
