In the support of a concrete form panel, an elongate beam, acting as a waler, is employed that is in the general cross-sectional shape of an I-beam having an outwardly opening pocket extending along one edge to retain a nailer for securing the beam to the form panel and a Y-shaped segment extending along the opposite beam edge. The Y-shaped segment is formed by legs which are parallel for one length thereof to define an outwardly opening cavity there between and then the legs diverge outwardly for a second length with oppositely directed flanges extending from the outer ends of the diverging second length of the legs. A bracket having a flat portion inserted into the beam cavity is secured in the cavity and has a tubular portion connected to the flat portion, the tubular portion accommodating a fastening element therewithin to fasten the bracket to a stiffener member, preferrably provided by spaced outwardly facing channels with the bracket tubular portion disposed between the channel webs.
