CONSTRUCTION HEAT- OR COLD-ACCUMULATION BLOCK AND WALL ERECTED OF ABOVE BLOCKS Russian patent published in 2007 - IPC E04C1/40 

FIELD: construction, particularly multilayered construction blocks and stones used for building wall erection and adapted to stabilize temperature inside room.

SUBSTANCE: construction block has several layers formed of cement based material. Block includes two extreme layers, one core layer and one face layer. Block is provided with the second face layer. Extreme layers are heat-insulating ones and are formed of porous concrete. Core layer is arranged between extreme ones and is made of fine concrete having high heat capacity and heat conductivity. Face layers lie in planes transversal to extreme and core layers and are arranged from opposite construction block ends. Face layers are hollow and made as sealed panel of two-ply sheet provided with inner stiffening ribs. Each cavity of sealed panel is defined by concrete layer in inner space of two-ply sheet along face panel perimeter. Each sealed panel has two connecting pipes with valves to be linked to pipelines. Fluid supply device is also discloses.

EFFECT: increased cold- or heat-accumulation capacity, possibility of inward and outward heat radiation.
