METHOD OF WARMTH-KEEPING OF EXTERNAL WALLS OF BUILDINGS AND STRUCTURES Russian patent published in 1998 - IPC

FIELD: construction. SUBSTANCE: the method consists in cementing of a heat-insulating block to the wall and subsequent application of an air-placed concrete layer onto its external surface and onto anchors. A "radoslav" block with an expanded polystyrene self-stopping warmth-keeping jacket frothed in a steel frame is used as the heat- insulating block. Prior to installation of the block, the wall surface is floated with hardening mortar, then a strip of continuous adhesive layer is applied in outline of the block surface, and the block is pressed to the wall to the working position, passing the anchors through the block frame and fastening the mesh reinforcement on them at a distance from the block surface, then a protective air-placed concrete layer is applied onto the mesh reinforcement over the whole open surface of the heat-insulating block. The thickness of the air-placed concrete layer makes up 1/1.2 to 1/7 of the thickness of the heat-insulating block. As a result, a multi-layer monolithic wall with frothed effective heat insulation is obtained. EFFECT: enhanced fire protection. 9 cl, 5 dwg
