Abstract
This invention relates to a corner alignment jig for box-like structures to be joined together in side-by-side or end-to-end assembled relation which comprises four horizontally adjustable vertically-disposed prealigned stanchions positioned to receive the box-like structure therebetween, fastener means for detachably connecting a corner post to the inside planar face of each stanchion, spacer means to be interposed between each stanchion and the corner post associated therewith to maintain a fixed spaced parallel relation therebetween, and jack means for temporarily elevating the box-like structure into position to have the four corner posts fastened thereto. The invention also encompasses the method of affixing corner posts to a box-like structure in fixed spaced parallel relation to one another which includes the steps of placing the box-like structure in position such that the stanchions are located at the corners thereof, temporarily fastening a corner post to each stanchion in fixed spaced parallel relation, raising the box-like structure up into proper position relative to the corner posts, permanently fastening the corner posts to the box-like structure, detaching the corne…
