Abstract
A wall form panel for use in constructing a poured concrete wall form is preferably extruded from aluminum and a plurality of sections which are joined together form the wall form panel. The outer side most sections of the wall form panel advantageously include integrally formed and extruded side flanges to provide enhanced load-bearing capability and reduce the likelihood of failure. The extruded panel sections are coupled together along longitudinally extending joint members and reinforced beams and struts are welded to the back face of the wall panel sections for added strength and rigidity. Advantageously, the wall form panel sections can be formed in a plurality of widths and joined together in various combinations to conveniently provide a variety of widths of wall form panels. The side flanges of the wall form panels includes holes for attaching pins and other associated hardware. Advantageously, a reinforced bushing is seated within the flange to provide increased strength and avoid material failure in this location.
