发明名称 Flexible drywall grid member for framing drywall structures
摘要 A curvable grid tee for suspending drywall capable of being configured vertically into convex or concave shapes comprising a series of identical web segments joined end-to-end, the segments being formed of sheet metal into a tee shaped cross section, the sheet metal of a segment being folded such that each segment has a vertical double layer stem with the stem layers joined at a common fold at upper edges thereof, the sheet metal at lower edges of each layer of the stem being bent outwardly to form a flange, a junction between adjacent segments permitting such adjacent segments to be angularly displaced relative to one another in a vertical plane such that the flanges are capable of supporting a drywall panel in a curved plane.

主权项 1. A curvable grid tee for suspending drywall capable of being configured vertically into convex or concave shapes comprising a series of identical web segments joined end-to-end, the segments being formed of sheet metal into a tee shaped cross section, the sheet metal of a segment being folded such that each segment has a vertical stem with two stem layers joined at a common fold at upper edges thereof, the sheet metal at lower edges of each layer of the stem being bent outwardly to form a flange, a junction between adjacent segments permitting such adjacent segments to be angularly displaced relative to one another in a vertical plane such that the flanges are capable of supporting a drywall panel in a curved plane, the stems of adjacent segments being in overlapping direct contact through a full range of convex shapes up to a 90 degree bend and a full range of concave shapes up to a 90 degree bend when the tee is viewed from below whereby the stems of adjacent segments can be fixed relative to one another with the tee in a desired convex or concave configuration without use of a separate splice plate.
