THREE-LAYERED RESOURCE-SAVING REINFORCED-CONCRETE PANEL Russian patent published in 2018 - IPC E04C2/06 E04B1/76 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular to the enclosing structures of industrial buildings. Three-layer resource-saving reinforced concrete panel includes a heat-insulating layer, external and internal reinforced concrete layers, interconnected by rigid connections, made in the form of reinforced concrete keys passing through the heat-insulating layer, and reinforced concrete fins located along the perimeter of the panel are additionally provided with at least two reinforced concrete keys that are located on opposite ends of the panel, and the reinforced concrete ribs in a section parallel to the layers of the panel have an area determined from the ratio of the panel area, the thickness of its middle layer, the coefficients of thermal conductivity of the fin materials, layers of the panel, reinforcement and insulation, as well as the required resistance to heat transfer. Coefficient of thermal conductivity of the material of reinforced concrete keys passing through the heat-insulating layer is 2.5–3 times higher than the coefficient of thermal conductivity of the material of reinforced concrete keys located on opposite ends of the panel. Heat-insulating layer is made from thin-fibre material and located in the form of twisted bundles longitudinally elongated throughout the panel length. Bundles of fine-fiber material in pairs of at least four are arranged in the form of sinusoids, longitudinally elongated along the length of the panel, the protrusions and valleys of which, when combined, are concentrators of moving seismic vibrations. Tangent of the first twisted beam of each pair has a direction in the clockwise direction, and the tangent of the helical line of the second twisted pair of this pair has a direction opposite the movement of the clockwise direction. Areas of greatest convergence of pairwise arranged twisted bundles are nodes that contribute to the formation of standing waves. At the same time, the ends of the three-layer resource-saving panel that contact the outside air surrounding the industrial building of the environment are covered with a nano-like glass-like film of tantalum oxide made by the ion-plasma method.

EFFECT: technical result consists in providing normalized heat-shielding properties in transitional periods of the year with increased humidity of the environment by eliminating the penetration of vaporous and fine-dispersed moisture into the heat-insulating layer.
