Abstract
A structural column assembly of the type used for erecting building structures and the like is bedded in a concrete footing formed in situ in an earthen hole. The column assembly includes a post whose bottom end is suspended above a floor of the hole by a stilt. The stilt includes a plurality of legs which extend from the post's bottom end and grip the hole floor through a plurality of cleats. The cleats help stabilize the column assembly during the concrete pour operation so that it does not shift out of position. The stilt legs are provided with a base pad, which is set below the bottom end of the post at a predetermined distance so that the concrete footing can be poured in a single operation immediately after the hole is formed. The stilt can accommodate posts made from wood, pre-cast concrete or any other known construction material. The stilts can be manufactured from formed flat steel or commercially available angle iron and channel stock.
