W-column for on-site erection of steel framed high rise buildings, and methods of use

摘要

An improved W-column provides flange tabs on the top-and-bottom outside corners of the W-column flanges, and vertical bolt-on connections to temporarily mount one column positioned by a crane on top of another by bolting the bolt-on connections to the corresponding flange tabs to properly align one W-column above another W-column. The improved W-column further allows the two vertically positioned W-columns also to be connected together by bolting the web of the upper W-column to the web of the lower W-column before permanently welding the two vertical W-columns together. Once positioned, these vertically aligned W-columns are can be permanently joined together with the Arcmatic® VertaSlag® ESW-NG welding process. In this manner all vertical W-column elements of a steel framed high rise building can be quickly erected.

主权项

1. An improved W-column, comprising in combination:
a) a longitudinal length of two parallel W-column flanges, each W-column flange comprising a flange top end cut at an acute angle and a flange bottom end cut at an acute angle, a flange outer surface comprising at least one bolt-on flange tab comprising at least one aperture, and a flange inner surface, each flange top end comprising at least two spacer blocks tack welded to the acute angle cut, flange top end; b) a longitudinal length of W-column web connecting the two parallel W-column flanges and comprising a web front surface, a web rear surface, a web top end further comprising at least one relief groove and a plurality of apertures through the web front surface and the web rear surface, a web bottom end further comprising at least one relief groove and at least one beveled side, and a plurality of apertures through the web front surface and the web rear surface; c) at least one moment connection between W-column cut flange ends, the at least one moment connection comprising a pair of front moment plates, each of the front moment plates corresponding to the web front surface and each flange inner surface corresponding to the web front surface at a predetermined position relative to the parallel W-column flanges and W-column web, and a pair of rear moment plates, each of the rear moment plates corresponding to the web rear surface and each flange inner surface corresponding to the web rear surface at the predetermined position relative to the parallel W-column flanges and W-column web; d) a web assembly affixed to the W-column web top end to align and connect the W-column web top end to a second W-column web bottom end when the second W-column is vertically positioned above the W-column; and e) a flange assembly affixed to the W-column flange outer surface at the W-column flange top and bottom ends to connect the W-column flange top ends to the second W-column flange bottom ends and align the respective flange top and bottom ends to provide dual, parallel equal sized weld cavities between the first W-column flange top ends and the second W-column flange bottom ends, comprising at least one bolt-on connection comprising at least one aperture and sized to be received by and connected to the at least one bolt-on flange tab with at least one fastener sized to correspond to the at least one bolt-on connection aperture and the at least one bolt-on flange tab aperture.
