FIELD: construction.
SUBSTANCE: invention relates to building blocks and moulds for making blocks. Building block is made in form of monolithic solid body in form of rectangular parallelepiped, on one side has groove, and on opposite side projection. Unit comprises ledges and slots located on opposite bases, channel located along perimeter of upper base, handles on end faces; wherein projections and slots are made with inclined side faces with formation of closed air circuits in seams between units; wherein the inclination angle of the grooves faces is greater than the angle of inclination of the protrusion faces to form sealed air circuits between the interlayer of the bonding material in the seams between the blocks. Form for making a concrete construction block is also described.
EFFECT: technical result for this invention is structural design of units, which provides convenience of laying and reduces time spent on masonry control.
