THREE-LAYERED WALL PANEL Russian patent published in 2005 - IPC

FIELD: building units, particularly wall panels used for erection of large precast panel buildings.

SUBSTANCE: wall panel includes reinforced outer and inner concrete layers and intermediate heat-insulation layer connected one to another with flexible metal ties. Heat-insulation layer is made of no-fine concrete including light porous filler encapsulated with binding material which binds filler particles so that binding material coats filler particles to form monolithic layer. Outer concrete layer is made of high-strength concrete. Inner concrete layer is created of claydite-concrete and has inner case formed of tubes having rectangular or square section. The case is made as closed rectangular frame with partitions located along panel perimeter and embedded in claydite-concrete layer for 15-25 mm depth measured from inner surface of the panel. Opposite ends of steel tubes forming major frame side extend to side panel surfaces and are opened to form mounting openings. Reinforcing net of outer layer is connected to inner layer case along perimeter thereof by flexible ties made as coarse net.

EFFECT: improved performance.
