Biodegradable structures for suspending anchor bolts
First Claim
1. A biodegradable assembly useful in suspending anchor bolts of a selected one of a plurality thickness into a poured concrete form characterized by a width and a length for immersion of portions thereof into the poured concrete, comprising:
- a generally elongate planar segment defined by longitudinally folding a corrugated cardboard panel into a plurality of overlying segments each having a longitudinal dimension greater than the span across said concrete form for forming a bridging suspension thereacross, each said segment further including a at least one opening aligned with corresponding openings in the other ones of said overlying segments for receipt of the shank of said anchor bolt in each said opening upon the overlying alignment of said segments; and
a corrugated cardboard retaining strip including a plurality of spaced holes each dimensioned for conforming interior receipt of said anchor bolt shank upon the repeated folding of said strip for common alignment of said holes for providing a suspending support of said anchor bolt within the common interior of said strips and said segments each being coated with a selected biodegradable color in accordance with the selected thickness of said anchor bolts receivable therein.

Abstract
An anchor bolt suspending array comprises a biodegradable bridging structure attachable across a concrete form or in cantilever from one side thereof conformed by folding longitudinally a corrugated cardboard panel into overlying segments each provided with a set of spaced openings that are aligned upon folding to receive the shank of an anchor bolt therein. A retainer either formed as a frustoconical cardboard pulp structure dimensioned to capture the anchor bolt shank end, or as an accordion folded corrugated cardboard strip perforated by spaced holes conformed to grasp the shank, is then useful to suspend the bolt from the bridging structure into the poured concrete. Both the retainers and the bridging structures can be color coded by a biodegradable coating in accordance with the size of the anchor bolt that is receivable therein.
