<p>STRUCTURAL CONNECTION A structural connection between adjacent ends of vertically superimposed precast columns in a structural framework of precast beams and columns. As in precast columns of the prior art sections of tubing are cast in the columns and extend longitudinally of them. However, the tubing at one end of the columns, rather than terminating at or just beyond the column end face, projects outwardly of the column a substantial distance, preferably through an opening formed through a beam at a beam-column intersection where the column joint is formed, and one end of a spindle is received in this portion of tubing and also in a second portion of tubing projecting only a slight distance from the opposite end of the adjacent column. A washer or washers may be loosely attached to or merely slipped over the spindle to engage the opposed ends of the tubing and transfer loads from an upper to a lower column. This construction provides shorter length spindles and a direct transfer of loads from upper to lower columns.</p> |
