THREE-LAYER REINFORCED CONCRETE PANEL Russian patent published in 2010 - IPC E04C2/06 

FIELD: construction.

SUBSTANCE: invention refers to construction, in particular - to barrier structures of industrial buildings. Three-layer reinforced concrete panel includes heat insulation layer, external and internal reinforced concrete layers joined to each other by means of rigid links arranged in the form of reinforced concrete keys passing through heat insulation layer and reinforced concrete ribs arranged along panel perimetre. Panel is additionally provided with at least two reinforced concrete keys, which are located at opposite ends of panel, and reinforced concrete ribs in section parallel to layers of panel have area determined from the ratio of panel area, thickness of its medium layer, coefficients of conductivity of rib, panel layers, reinforcement and insulator materials, and also required resistance of heat transfer. Coefficient of heat conductivity of material of reinforced concrete keys passing through heat insulation layer 2.5-3 times exceeds coefficient of heat conductivity of material of reinforced concrete keys arranged at opposite ends of panel.

EFFECT: maintenance of panel thermal properties under variable weather conditions.
