Abstract
A panel connecting member for use with tie rods and panels for a concrete forming structure, which panels each have bolt holding structures along the edges thereof. This member is tubular and has two connecting flanges extending outwardly from one side. Slots to receive bolts are cut in the edges of these flanges. First and second aligned holes are provided in opposite sides of the tubular member for passage of a tie rod. Channel-forming, longitudinally extending projections are provided on the side of the tubular member opposite said one side. These projections are adapted to receive between them flanges provided on the edges of the panels. The preferred panel has a corrugated, aluminum core member substantially covering an interior space of the panel defined by two siderails and two end rails. Inner and outer structural sheets extend between these two sets of rails and are both connected to said core member.
