Wall assembly

A wall stud for use with a support channel, the support channel being elongated along a longitudinal axis and being formed from a base wall with two spaced side walls extended perpendicularly from the base wall for forming a U-shaped cross-sectional configuration for the channel having a pre-determined width between the side walls of the channel, wherein the channel comprises at least one set of ratchet teeth formed on each side wall of the support channel, the ratchet teeth extending inwardly into the U-shaped cross sectional configuration of the channel and comprising a plurality of adjacent teeth separated by grooves to define a sawtooth configuration for the teeth, which comprises:

• a stud having a pre-determined cross-sectional length extending between two opposed transverse sides of the wall stud which generally corresponds to the width between the side walls of the channel such that the stud can have one end thereof installed transversely across the channel with the transverse sides of the stud being located adjacent the side walls of the channel, and further including at least one spline located on each transverse side of the wall stud, wherein the spline is dimensioned to be received in the grooves between adjacent ratchet teeth for forming a ratchet engagement with one of the sets of ratchet teeth, whereby the ratchet engagement extends between each side of the wall stud and one of the side walls of the support channel.
