PRE-FABRICATED PANEL Russian patent published in 2008 - IPC E04F15/24 

FIELD: construction.

SUBSTANCE: pre-fabricated consists of the upper flat plate and lower plate provided with a set of molded projections, and peripheral supporting edge with flange connected with the upper plate edges around the whole perimeter. Each projection surface is realised as spherical zone with smaller base locating in the bottom plane of the upper plate. Larger base is situated in the initial plane of plate. Projections are implemented as mutually perpendicular lines, which are parallel to panel sides. Projections are placed at a equal distance from each other. Closed space between plates is filled up with self-setting material. As a result beam system is formed in the form of crossed beams with variable width and height. End of beams are joined with peripheral supporting edge. Distance between adjoining parallel lines of projections is 1.1-1.3 of the larger projection base diameter.

EFFECT: improved bending rigidity of panel.
