SHEET OF CELLULAR POLYCARBONATE WITH ARCHED CELL Russian patent published in 2015 - IPC B32B3/12 E04C2/20 

FIELD: construction.

SUBSTANCE: invention relates to structural materials for use in the field of glazing of small-size structures and relates to a sheet of cellular polycarbonate. The sheet has partial bulge of the upper wall and stiffening ribs. It is made from polycarbonate by the method of extrusion and represents a laminated sheet material. Cells within the sheet are made with cross section in the form of a square having arched curves due to reinforcement of a unit of coupling of each stiffening rib to the upper wall of the sheet. Reinforcement of coupling units of stiffening ribs is made by arrangement of symmetrical bulges in areas of stiffening ribs adjacency to the upper wall of the sheet within its cell.

EFFECT: invention provides for improved technical properties of a finished item, increased total bearing capacity of a finished item, increased single-sided flexibility of an upper wall in a finished item, increased area of transmission of visible spectrum of light due to increased total area of an upper wall of each cell.
