ABSTRACT:
An elongated sheet metal corner framing element is provided having an essentially "E" shaped cross-sectional area. The center point of the "E" is longer than the end points and one section of the "E" is configured to engage a flange of an H- or I-beam structural member. The other section of the "E" extends from the structural beam and forms a squared open corner section along the entire beam length for attachment of wallboard thereto. The extra length center point of the "E" configuration permits shooting (with power driven pins or nails) of the corner element to the beam at spaced intervals along the element length where more than a frictional fit is desired or required. The corner element may be cold-rolled, extruded, or formed of a flat or square bottom U-channel with an uneven side sheet metal angle attached therein via spot welding or metal screws. An alternate embodiment for covering concrete columns includes an outside corner element having a cross-sectional area in the shape of an open square with ear flange extension 91,92 serving as attachments for element 80 to the concrete column.
