Abstract
Apparatus for assisting in weld assembling a box column from a tack-welded pre-assembly of planar plate components. The apparatus features (1) an elongate frame defining a rotational-assembly axis, and (2) plural pre-assembly-receiving, rotational support structures mounted at spaced locations on the frame—each support structure including (a) an openable/closable yoke possessing a collar-reception zone, (b) an openable/closable collar rotatably receivable within this reception zone, and possessing a central throughpassage having a cross-sectional configuration which is larger than that of a box-column which is to be assembled, and (c) a pair of removably-collar-attachable, throughpassage clamping shoes for forming cooperatively, within the collar throughpassage, a window for complementarily, receiving extension therethrough of a box-column pre-assembly's cross section. A so received pre-assembly is rotatable about the rotational-assembly axis to position the existing seams of adjacency between the pre-assembly plate components for full-strength welding by an automated, traveling welding instrumentality.
