FIELD: construction.
SUBSTANCE: invention may be used in production of lime-sand and ceramic bricks, and also hollow blocks made of foam concrete and other mixes. Masonry unit has partitions in bed sides and through cavities of rectangular section. Heat insulation inserts made of cane fiber or cork plates are tightly installed in cavities. Cavities on both sides are closed by metal covers. Blind cavities are arranged in section in the form of truncated cone, their lower wider part is pneumatically communicated with its vertical holes to atmosphere. Ratio of unit wall thickness δw to width δc of cavity makes 0.9÷1.3. Ratio of partition thickness δp to thickness of unit wall δw makes 0.8÷1.0. Ratio of outlet opening diameter doo of blind cavity to diameter of its wider part dwp makes 1:2.
EFFECT: higher strength of wall made of suggested masonry unit, and increased heat engineering properties.
