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.

Dependent claims

A framing structure for attaching protective wallboard covering to a H- or I-beam structural member comprising:

an elongated sheet metal corner element extending the length of the structural member to be covered and having an essentially "E" shaped cross-sectional area,
said "E" shaped cross-sectional area of said corner element having a straight back section, a first leg perpendicularly extending from one end of said straight back section and forming one end of said "E" shaped cross-sectional area,
a second leg perpendicularly extending from the other end of said straight back section and in the same direction as said first leg and forming the other end of said "E" shaped cross-sectional area,
a third lege perpendicularly extending from said straight back section and disposed in spaced relationship between said first and said second legs,
said third leg forming the center of said "E" shaped cross-sectional area and being longer than said first and said second legs,
said first leg, said third leg and a portion of said straight back forming a first open section in said "E" shaped cross-sectional area of said corner element,
said first open section of said corner element being configured to frictionally engage a flange edge of a H- or I-beam structural member,
said second leg, said third leg and a portion of said straight back forming a second open section in said "E" shaped cross-sectional area of said corner element,
said second open section of said corner element extending laterally from said H-or I-beam and forming a squared open corner structure for attachment of protective wallboard thereto.
