An apparatus for connecting collar components to an elongate member is disclosed. The apparatus includes a frame structure having a central opening that is configured to receive an elongate member and that includes at least a first gripping station and a second gripping station. Each gripping station includes a reference surface and a clamp device that is configured to force a collar component against the reference surface. The first and second gripping stations are configured to control relative spatial location of a first collar component held by the first gripping station relative to a second collar component gripped by the second gripping station, prior to connecting the first and second collar components to the elongate member.

A full-moment column collar is disclosed, including four collar flange components and four collar corner components. Each collar flange component includes an upper transverse element and a lower transverse element, connected by a bridging member. Each collar corner component includes first and second expanses defining a corner and a standoff portion extending from the corner, the standoff portion having a distal T-shaped structure. Each collar corner component is configured to connect two adjacent collar flange components, and each collar corner component has a multi-axis alignment structure extending from a bottom end portion for vertically positioning a lower transverse element of a respective collar flange component.

A beam-end component welding fixture including a stand having a central horizontal axle mechanism and a housing. A handle is mounted on a first end portion of the axle mechanism and a rotatable plate structure is mounted on a second end portion of the axle mechanism. A column connecting simulator is attached to the plate structure and configured to support a beam-end component.

Methods and apparatus for assembly of moment connection components

A collar flange assembly welding fixture is disclosed, including a stand, a circular mount structure, and a support assembly which are configured to provide access to a front side and a back side of a collar flange assembly held by the support assembly. The stand has a plurality of circumferential bearings equidistant from an axis of rotation, the circular mount structure is rotatably supported by the circumferential bearings, and the support assembly is configured for mounting on the circular mount structure.

A collar flange assembly clamping tool is disclosed, including an axle having a long axis, and a pair of arms mounted on the axle. At least one of the arms is slideable along the long axis. Each arm includes a primary axis perpendicular to the long axis of the axle, a proximal end portion, and a distal end portion with a tab. The proximal end portion includes a clamping device that moves in a direction perpendicular to the primary axis of the arm and the long axis of the axle.

A lifting tool assembly is disclosed, including a crossbar having a long axis spanning between first and second end portions. A first hook member is pivotably suspended from the first end portion and a second hook member is pivotably suspended from the second end portion. The end portions are symmetrically angled relative to the long axis and each hook member includes first and second finger structures.

A gripping apparatus is disclosed, including a rigid housing having a slot with an engagement axis, and a shaft extending parallel to the engagement axis. The apparatus further includes a tab member on a distal end of the shaft and a rotational actuator on a proximal end of the shaft. The rotational actuator is configured to rotate the shaft, causing the tab member to move between a hooked position and an unhooked position.

A precision fabrication form system for preparing a poured-concrete (with upwardly projecting anchor bolts) footing for anchorably supporting the base of an elongate, upright, structural-frame column. The system includes a reversibly stackable plurality of independent, intercooperative, fabrication-form templates&#x2014;grade, pedestal, base-plate, anchor-bolt and centerline&#x2014;reversibly assembleable in a predetermined stack order above a prepared ground excavation into which concrete pouring to be associated with such a footing is to occur, certain ones of these templates being infinitely adjustable relative to one another and to the ground in both pre-pour and post-pour conditions to accommodate staged, precision, X-axis, Y-axis, Z-axis, and pitch, roll and yaw axes dispositions for the concrete and anchor bolts in such a footing.

Modular, six-axis-adjustable, concrete-pour form-structure system

I-beam-attachable lifeline system, including methods and apparatus, for worker safety. In some embodiments, the system may comprise a frame structure including upright columns and horizontal I-beams. The system also may comprise a pair of fittings connected to a horizontally-spaced pair of the I-beams. Each fitting may have a first hook component and a second hook component received on respective opposite edge regions of a flange of an I-beam of the pair of I-beams and attached to one another with a fastener such that the fitting spans the flange transversely and is supported by the I-beam. The system further may comprise a cable having opposite ends connected to the pair of fittings.

A pipe-support system including a pipe-support frame structure having plural, substantially horizontal, pipe-support levels supported by columns including a distribution of side columns uniformly spaced along at least one side of the frame structure, and featuring selectively graduated, support-level-indifferent, lateral-connectivity access for quickly available, removeable, outrigger gravity attachment to the frame's side columns, through gravity catch and hook structures, of modular, outrigger, lateral, worker-platform scaffolding either as individual scaffolding units, or as assemblies of plural, individual units, all such units deriving vertical support through outrigger connections made to the frame structure.

Plural-story, pipe-support frame system with modular, removably attachable lateral-worker-support scaffolding

A system for handling various structural building components including a pick and stack-registry lug which is anchorable to the top of a building component for handling that component in either one, or both sequentially, of its two, pick and stack-registry functional modes, (b) a clamshell-style, releasably lockable clasp adapted to receive and close capturingly upon the lug under operational circumstances with the lug anchored to the top of a building component, and ready to function in its pick category of component-handling behavior, and (c) a guide socket includable in the base of a building component functional for camming, guided reception of a lug with the lug then functioning in its stack-registry mode of behavior to facilitate overhead stack registering of two building components in relation to the lowering of an overhead component onto the top of an underlying component whose top also has a lug anchored to it.
