Abstract: A building construction includes a wall, floor or ceiling assembly wherein a pair of walls or the like each include adjacent wallboards having edge formations defining a mating tongue and groove configuration. The wall pairs are supported in a stable manner by metal posts having a variety of edge flange configurations and which are captively secured within the confines of each wallboard tongue and groove joint. Tight joints between adjacent wallboards and the posts are insured by the formation of one or more kerfs in the area of the wallboard joints and which engage portions of the entrapped posts to provide enhanced rigidity throughout the wall height. By angling the post edge flanges outwardly and providing correspondingly angled wallboard kerfs, maximum structural integrity is achieved with use of minimum thickness wallboards.

Abstract: A wall system includes a plurality of wall sections secured to one another or to fixed building structure through a peripheral framework of profile elements each having a web bounded by pairs of large and small flanges respectively defining deep and shallow grooves. The shallow grooves serve to engage and retain the edges of panels which are held against the large flanges while rigid splines are insertable within opposed deep grooves of adjacent profile element-equipped panels to interlock the plurality of wall sections. By employing various width splines, alternate spacing between wall sections is achievable and various supplemental members such as shelf brackets or trim elements may be installed over the exposed portions of the splines.
