Abstract: A corner stud (50) has intersecting first and second walls (52, 54) that back up corner edge portions of wallboard panels (40, 42) that meet at the inside corner. The walls (52, 54) are braced by walls (64, 70) and flanges (76, 78). Wall (52) and wall (70) may be parallel to each other and to flange (76). Wall (54) and wall (64) may be parallel to each other and flange (78). The stud (50, 52, 200, 202) may have a web bent about a longitudinal axis to form web parts separated by an inside angle (a). The angle a may be an obtuse angle below one hundred eighty degrees (180°) to about two hundred seventy degrees (270°).

Abstract: A plurality of studs (14) are spaced apart relative to each other. Upper end portions (32) of the studs fit into an upper channel space (22) and lower end portions (34) fit into a lower channel space (30). The lower channel space (30) is defined in part by a pair of spaced apart sidewalls (24, 26). Screw fasteners (52) extend through the sidewalls (24, 26) and connect them to the lower end portion (34) of the stud (14). The studs (14) have upper ends that are spaced from a web (20) forming the upper boundary of the upper channel space (22). Vertical elongated slots (48, 50) are provided in the sidewalls (38, 40) of the studs (14). Screw fasteners extend through the sidewalls (16, 18) of the upper channel member (10) and then extend into and through the slots (48, 50). The heads of the screw fasteners (52) bear against the sidewalls (16, 18) when the screw fasteners (52) are tightened.
