BAR-LIFTING PANEL Russian patent published in 2017 - IPC E04B5/02 

FIELD: construction.

SUBSTANCE: bar-lifting panel comprises a panel body made of a light and strong material with longitudinal hollow cavities. Inside the panel there are bar-lifting elements, arranged in the longitudinal direction in two rows, and in the transverse direction their number is unlimited and determined by the panel width. Each bar-lifting element comprises two longitudinal rectangular E-shaped vertical cavities, not connected pneumatically to each other, symmetrically arranged and facing each other with their three lateral longitudinal channels closed from both butt sides. The lowest lateral longitudinal channels of the E-shaped cavities are blind, and each of the upper lateral longitudinal channels is pneumatically connected to a corresponding vertical longitudinal channel opening onto the upper panel surface, and by means of an inclined longitudinal channel - with an internal cavity of the corresponding longitudinal pipe closed from both butt sides. Both medium longitudinal channels are connected to the inner cavities of the respective longitudinal pipes closed from both butt sides. All the opposite walls of the cavities and channels are equal in area. All the arc surfaces of cross-lying pipes are equal in area. On the upper surface of the panel, two covers are installed in the guides with the possibility of moving transversely by means of a screw mechanism, having through longitudinal windows equal in width and length to the vertical channels of the panel. To reduce the weight inside the panel, longitudinal cavities not associated with the bar-lifting elements are made in free places. At the lower part of the panel, four supports are made.

EFFECT: improving the operation characteristics of the panel.
