ABSTRACT:
A structural member for use in concrete forming structures and the like is disclosed. The member comprises a pair of spaced parallel tubular members interconnected by means of opposed webs. The combination defines an enclosure extending the length of the tubular members. Each of the webs attaches to a side of the tubular member opposite the enclosure. The outer surface of each web includes opposed flanges, which in combination with the web, define an open bolt slot that extends the length of the structural member. This structural member is particularly useful as an upright in concrete shoring.
