Sheet metal intersection studs

Abstract

A corner stud ( 40 ) has a four-sided post portion ( 42 ) that sits into a corner region of a framing wall. The post portion includes a pair of flanges ( 92, 96 ) which form a right angle inside corner at the inside corner of the framing wall. Edge portions of wallboard panels ( 108, 110 ) connect to the flanges ( 92, 96 ). A post portion 112 of an intersection stud ( 110 ) fits within the tracks at a location between the corners. Inside corners are formed by flanges ( 148, 160 ) and ( 154, 166 ) against which edge portions ( 180, 182 ) of wallboard panels ( 184, 186 ) and ( 188, 190 ) are connected. The edge portions ( 180, 182, 188, 190 ) of the wallboard are connected to and backed up by the flanges ( 148, 160, 154, 166 ).
