FIELD: construction engineering; external walls of heated buildings. SUBSTANCE: ceramic stone has on its top edge two vertical rectangular through holes equidistant over its longitudinal axis from middle of its length and is provided with slotted-ridge vertical members on side edges; ridges on left-hand edge are opposing the slots on right-hand edge; two additional vertical slots are provided on each side edge filling them with fine-grain in-situ concrete for reinforcing and compacting, and with solution; depth of mentioned slots is half the width of vertical through holes arranged symmetrically to longitudinal axis of stone relative to slots. Sides of vertical through holes are measuring between 3.5 and 4.5 cm. EFFECT: improved heat-insulating and monolithic properties, tightness, and strength of brickwork; provision for dispensing with plastering. 2 dwg
