Abstract
A triangulated rib structure including first, second and third sets of "egg-crate" interlocking ribs. The first set is oriented in a predetermined direction such as the horizontal or vertical coordinate, and the second and third sets are oriented at angles of first and second senses, respectively, thereby forming triangulated spaces which are inherently rigid. The individual ribs have edges falling adjacent to a desired overall reflector surface, each of these being precut before assembly to provide the required line of curvature as a function of the individual ribs placement. Each rib is itself a planar piece, and the "egg-crate" interlocking slot joints may be stabilized with one or more seam welds. A conductive mesh forming the actual contoured reflector surface is conformed to the desired contoured shape and affixed as by tack-welding to the edges of the ribs adjacent the contoured surface.
