FIELD: construction industry.
SUBSTANCE: invention can be used for erecting buildings and constructions. Building block consists of more than two rigid plates made from reinforced concrete and arranged vertically, and heat-insulating layer is installed between at least two of them. The above plates are attached to neighbouring plates with a gap not exceeding plate thickness by means of rigid straps made with possibility of compressive and tensile operation. Straps do not pass through block plates. Location of straps in neighbouring gaps does not coincide with each other. External block plates are made from concrete with additions ensuring improvement of their operating and/or decorative properties. Block ends are provided with protrusions and hollows made with possibility of being aligned during block work.
EFFECT: providing increased strength of building block and improving its heat-insulating properties.
