Box column assembly

1. Apparatus for promoting the weld assembling of an elongate box-column from a rectangular-cross-section pre-assembly of elongate, adjacent, planar plate components having a long, central axis which is to become the long, central axis of a finally assembled box column, said apparatus comprising

an elongate, substantially horizontal frame possessing a long axis

an elongate, substantially horizontal, rotational-assembly axis operatively associated with and disposed above said frame,

at least a pair of pre-assembly rotational support structures mounted at spaced locations on said frame designed to receive, and to furnish support for rotation about said rotational-assembly axis for, such the pre-assembly,

each support structure including, operatively centered on said rotational-assembly axis,

(a) an openable and closable, dual-section, split-structure yoke defining an openable and closable collar-reception zone which, with the yoke closed, is circular in configuration,

(b) an openable and closable, dual-section, split-structure collar, which is circular in perimetral outline when closed, and removably receivable, and rotatable effectively, within said collar-reception zone, said collar, when closed, possessing a central, non-rectangular throughpassage defined by a first pair of opposite, straight-angle sides, and a second pair of opposite, outwardly-directed-obtuse-angle sides, opening of a collar splitting its throughpassage, along a line connecting the vertices of its obtuse-angle sides, into two, equal and matching-configuration, wedge-shaped troughs, and

(c) a pair of removably collar-attachable, double-wedge clamping shoes, one for each obtuse-angle side of said throughpassage, said shoes, when attached to the collar, and with the collar closed, forming, in cooperation with said throughpassage's straight-angle sides, a rectangular-outline window for confinedly, and complementarily, receiving extension therethrough of the rectangular cross section of the box-column pre-assembly in a condition with the pre-assembly's long, central axis substantially coincident with said rotational-assembly axis.

2. The apparatus of claim 1 which more specifically is for promoting the weld assembling of the box-column from the pre-assembly of elongate, planar plate components having long, lateral edges, pairs of which edges, respecting adjacent plate components in the pre-assembly, lie parallel and adjacent one another to define, collectively in the pre-assembly, plural, elongate, parallel, inter-plate-component, weld-awaiting interface seams, and wherein said yokes and collars are respectively configured whereby opening of said yokes and collars is effective to expose, in a manner facing upwardly to accommodate welding access, a pair of such seams.

3. The apparatus of claim 2 , wherein each section in each yoke and in each collar is generally arcuate and semicircular in configuration, and each yoke and collar is structured to promote cooperative openings thereof about a substantially horizontal plane disposed above said frame.

4. The apparatus of claim 2 which further comprises, operatively associated with said frame, a traveling welding instrumentality having a pair of laterally spaced welding heads disposed appropriately above the frame, and an elongate track supporting said instrumentality for movement along a travel path paralleling said rotational-assembly axis and for thereby guiding said welding heads along laterally spaced welding paths that are disposed, respectively, immediately overhead, and parallel to, any open-yoke and open-collar, upwardly exposed interface seams in any pre-assembly then supported by said support structures.

5. The apparatus of claim 2 which is constructed in a manner whereby, with said shoes attached to an associated collar, opening of the collar and the associated yoke under, circumstances with the pre-assembly then supported by said support structures, is permissible without de-attaching the shoes from the collar.

6. The apparatus of claim 1 , wherein said rotational support structures are repositionably mounted on said frame.

7. Apparatus for assisting in the final welding assembly of an elongate, square-cross-section, structural-building-frame box column from a box-column pre-assembly of elongate, adjacent, planar, plate components that are to form the sides of such a finally assembled box column, and where the pre-assembly has a square cross section which is to become that of the intended, finally assembled box column, and a long, central axis which is to become the long, central axis of such a finally assembled box column, said apparatus comprising

an elongate, substantially horizontal frame,

an elongate, substantially horizontal rotational-assembly axis disposed above, and associated operatively with, said frame,

plural, openable and closable, dual-section, split-structure yokes mounted on said frame at plural, spaced locations distributed therealong, each yoke defining an upright, openable and closable collar-reception zone which, with the yoke closed, is circular in configuration, and centered on said rotational-assembly axis,

for each yoke, an openable and closable, dual-section, split-structure collar, which is circular in perimetral outline when closed, and removably receivable, and rotatable about said rotational-assembly axis when received, effectively, within the yoke's associated collar-reception zone,

each collar, when closed, possessing a central, non-square, polygonal throughpassage defined by a first pair of opposite, straight-angle sides, and a second pair of opposite, outwardly directed, obtuse-angle sides, opening of a collar splitting its throughpassage, effectively along a line connecting the vertices of its obtuse-angle sides, into two, equal and matching-configuration, wedge-shaped troughs, each throughpassage being centered on said rotational-assembly axis under circumstances with its associated collar closed, and disposed for rotation about the rotational-assembly axis, and

for the obtuse-angle sides associated with the throughpassage in each collar, a pair of removably collar-attachable, double-wedge clamping shoes, one for each obtuse-angle side of the throughpassage, said shoes, when attached to the associated collar, and with the collar closed, forming, in cooperation with said straight-angle sides of said throughpassage, a square-outline window for confinedly, and essentially complementarily, receiving extension therethrough of the square cross section of the box-column pre-assembly,

the box-column pre-assembly, when so received by said throughpassages in said collars, being disposed for rotation about said rotational-assembly axis in a condition with its associated long, central axis being substantially coincident with the rotational-assembly axis.

8. The apparatus of claim 7 which more specifically is for promoting the weld assembling of the box-column from the pre-assembly of elongate, planar plate components having long, lateral edges, pairs of which edges, respecting adjacent plate components in the pre-assembly, lie parallel and adjacent one another to define, collectively in the pre-assembly, plural, elongate, parallel, inter-plate-component, weld-awaiting interface seams, and wherein said yokes and collars are respectively configured whereby opening of said yokes and collars is effective to expose, in a manner facing upwardly to accommodate welding access, a pair of such seams.

9. The apparatus of claim 8 , wherein each section in each yoke and in each collar is generally arcuate and semicircular in configuration, and each yoke and collar is structured to promote cooperative openings thereof about a substantially horizontal plane disposed above said frame.

10. The apparatus of claim 8 which further comprises, operatively associated with said frame, a traveling welding instrumentality having a pair of laterally spaced welding heads disposed appropriately above the frame, and an elongate track supporting said instrumentality for movement along a travel path paralleling said rotational-assembly axis and for thereby guiding said welding heads along laterally spaced welding paths that are disposed, respectively, immediately overhead, and parallel to, any open-yoke and open-collar, upwardly exposed interface seams in any pre-assembly then supported by said support structures.

11. The apparatus of claim 8 which is constructed in a manner whereby, with said shoes attached to an associated collar, opening of the collar and the associated yoke under, circumstances with the pre-assembly then supported by said support structures, is permissible without de-attaching the shoes from the collar.
