Abstract: A reusable coupler for accurately setting a threaded anchor in a concrete foundation to be poured having an attachment member for releasable attachment to a supporting structure and a tongue member that is formed with means for releasably gripping the threaded portion of the anchor. The releasable mechanical grip of the reusable coupler on the anchor is strong enough to insure that the orientation and the placement of the anchor will be maintained when the lower portion of the anchor is subjected to laterel forces during the concrete pour. The reusable coupler utilizes a one-piece design, wherein the mechanical gripping means works independantly from the attachment member. The reusable coupler can attach to a single form member for a concrete structure.

Abstract: A reusable column mold particularly adapted for use in casting concrete pillars or columns, that mold including a sheet of flat, flexible material which can be rolled into a columnar configuration to erect the mold form and which can be readily stripped from a set-up concrete column cast into the mold form. In preferred form, the flat sheet is of a rectangular configuration and is characterized by a plurality of tongues on one side edge which, when the sheet is rolled into columnar configuration, are adapted to fit into slots in the sheet located on one of a series of slot lines (the slot lines are parallel to the sheet's tongued side edge and are positioned intermediate the sheet's side edges); the cross-sectional area of the mold form is determined by that slot line of the sheet which cooperates with the sheet's tongued edge.
