Abstract
Multipurpose concrete form panels are constructed using cross stiffener members for resistance to deflection under load. Each of the cross stiffener members is formed of a base strip of metal with a pair of parallel ribs of hat section extending therefrom and joined to opposite side rails of the form panel. Rail stiffener strips are fastened to the side rails on alternate sides of the rail for added rigidity. Bores for connecting pins extend through the side rails to join the panels side by side to form a wall or, using a corner form, to form a column. Bores through the side rails are positioned between the cross stiffener members and between the ribs in each pair of ribs for joining the side rails together with continuity of the cross stiffener members for maximum dispersal of stress. Holes for wall ties extend through the face of the form panel and between the ribs in each pair of ribs. Fasteners for the ends of the wall ties engage the pairs of ribs to disperse localized stress.
