Abstract
A structural component, such as a load-bearing column or a floor panel, is initially made undersize between two opposed faces and is brought to accurate size and the angularity of said faces made accurate, by locating the component relative to a reference surface, with a gap between that surface and one of the faces, that face is provided in the gap with a layer of settable material capable of adhering to the face, and this material is squeezed by relative adjustment between the reference surface and an abutment to give the component the desired accuracy. A load-bearing structure of room height, consisting of two such columns spaced apart with a cross-member between them, for rigid attachment to such a floor panel, is made by adjusting the two columns in such manner that they are parallel, the distance between them conforms substantially to an accurately predetermined value, bearing surfaces at their corresponding upper and lower ends are level with one another, and rigidly connecting eachh column to the cross-member by tolerance-accommadating joints spaced apart in the height of each column.
