WALL PANEL Russian patent published in 2017 - IPC E04C2/28 E04B1/74 

FIELD: construction.

SUBSTANCE: invention relates to construction, in particular to wall panels for constructing buildings, houses and similar structures. Wall panel contains a concrete plate, two crossbars, two ribs, the first heat-insulating plate, two second heat-insulating plates, two third heat-insulating plates, two U-shaped elements. Concrete plate is equipped with the outer surface, the inner surface, two side surfaces, the upper and the lower surfaces. Outer surface and the inner surface are made in the form of rectangles and have larger square if compared to the other surfaces of the concrete plate. Side surfaces are located on opposite sides, the upper surface is located on opposite side from the lower surface. One crossbar is located on the outer surface along its upper edge from one side surface to the other one, the other crossbar is located on the outer surface along its lower edge from one side surface to the other one. Ribs are arranged on the outer surface parallel to the side surfaces from the upper surface to the lower surface. Herewith the ribs are spaced from an appropriate to each of them side surface. Surface of each of the ribs opposite to the outer surface is located from the outer surface at a larger distance than surfaces of the crossbars opposite to the outer surface. First heat-insulating plate is arranged between the ribs flush with the ribs surfaces opposite to the outer surface. Second heat-insulating plates are located along corresponding to each of them ribs and with overlap onto the first heat-insulating plates. Each U-shaped element is arranged vertically so, that it covers the relevant second heat-insulating plate on the side opposite to the outer surface. Third heat-insulating plates are located on the side of ribs facing towards the appropriate side surface, between crossbars, from the outer surface to the surface of large rib opposite to the outer surface.

EFFECT: technical result is improvement of heat-insulating properties of joints of adjacent wall panels and arranging the concrete plate in the zone of positive temperatures in case if there is heating of the building.
