Slab-embedded precision height-and-tilt-adjustable plinth anchoring for a column base

摘要

Precision-adjustable, plinth structure for anchoring the base of a building-frame column to a poured concrete slab including (a) a first load-reaction structure embeddable in a pre-cured (i.e., wet, and not yet fully cured) pour of concrete which will cure/harden to form such a slab, (b) a second load-reaction structure disposed above the first load-reaction structure, anchorable to the base of a column, and including at least one depending retention element which extends downwardly toward the first load-reaction structure so as to be embeddable in the same still-wet concrete pour, and (c) adjustable, differential, load-reaction-interaction structure load-transmissively and operatively interposed the first and second load-reaction structures, and offering plural, laterally spaced adjusters which are manipulable from above selectively to shift the two load-reaction structures relative to one another in both elevational and tilting senses. The methodology of the invention includes (a) placing a precision, position-adjustable plinth in an intended slab zone, (b) pouring concrete into that zone so as effectively to engage the placed plinth, (c) adjusting, as desired, the position of the plinth in three-dimensional space before full curing of the poured concrete, and (d) locking the adjusted position of the plinth through curing of the poured concrete.
