FIELD: construction.
SUBSTANCE: invention relates to construction, namely to construction materials, particularly blocks or stones, and can be used for construction of walls of civil and industrial buildings and structures with required thermal resistance for different climatic conditions of their operation. Construction unit comprises an external bearing unit with the same length and width and an internal heat-insulating structural unit retained from the inside by the structure of the external unit. Building block is made with possibility of connection in horizontal and vertical planes with other blocks by dense placement thereof in each other due to that on upper pastel surface of indoor unit there is a projection, and on bottom - corresponding to it with clearance recess, forming together with corresponding ledges and recesses of other units tight seamless vertical socket connection, and on one of header and spoon outer surface of external unit symmetrical identical projections are arranged, and on the outer surface of the outer unit, which is opposite to them, are recesses corresponding to them with a gap, which form together with the corresponding projections and recesses of other units a sealed seamless horizontal connection joint. Version of the block is also described.
EFFECT: objective of invention is reduction of labour intensity of erection of walls and improvement of their energy-saving characteristics.
