Wall panel assemblies

A wall panel assembly in a building having a floor and walls, said panel assembly comprising a pair of co-planar panels having adjacent spaced end edges, opposite end edges secured to respective walls and lower edges secured to the floor, a first partial column member extending upwardly from the floor to substantially the height of the panels on one side thereof and also extending transversely across the space therebetween, a second partial column member extending upwardly from the floor to substantially the height of the panels on an opposite side thereof and also extending transversely across the space therebetween, each partial column member comprising a main portion extending transversely across the space between the panels and outwardly spaced from the respective side thereof, and intermediate portions extending from opposite ends of the main portion to transversely and outwardly extending flanges overlying the panels, the main portion of each partial column member being substantially parallel to the transversely extending flanges, and the intermediate portions being substantially perpendicular to the main portion and the transversely extending flanges, first removable bolt means passing through one flange of the first column member, one of the panels and one flange of the second column member to secure the column members to said one panel, and second removable bolt means passing through the other flange of the first column member, the other panel and the other flange of the second column member to secure the column members to the other panel, with the first and second column members forming a vertical hollow column with the adjacent spaced end edges of the panels, said vertical hollow column containing no structural support member.
