EXTERNAL HEAT-SAVING FIREPROOF SHELL OF A BUILDING MADE OF POLYSTYRENE CONCRETE ENCLOSING STRUCTURES Russian patent published in 2022 - IPC E04B1/76 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction and concerns the external enclosing structures of buildings with the use of particularly light environmentally friendly polystyrene concrete. The solution of this problem is achieved by the fact that for the external heat-saving fireproof shell of a building made of polystyrene concrete enclosing structures, prefabricated or monolithic, consisting of exterior walls and reinforced concrete coverings and floors insulated with polystyrene concrete, the exterior walls are made in the form of prefabricated products: wall blocks, panels and overhead bridges with a density of D300-D600, or a monolith with a density of D400-D600 made of non-combustible polystyrene concrete containing expanded polystyrene granulated in an amount of no more than 1.9 wt. % in relation to Portland cement, and the insulation of reinforced concrete coatings and floors is carried out with the use of low-combustible polystyrene concrete thermal insulation boards with a density of D150-D225 of increased strength grades M2.5-M7 and the creation for them of a fire-resistant layer of non-reinforced or reinforced cement-sand screed with a thickness of 5-40 mm.

EFFECT: objective of the invention is to create an outer shell of a building made of polystyrene concrete enclosing structures with improved fire protection, heat-saving and technical and economic characteristics.
