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.

Claims

1. A biodegradable assembly useful in suspending anchor bolts into a poured concrete form 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 plurality of longitudinally spaced openings of generally equal size aligned with corresponding openings on the other ones of said overlying segments for receipt of the shank of said anchor bolt in the common interior thereof; 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 a selected group of said corresponding openings.

2. Apparatus according to claim 1, wherein:

said strips and said segments are each coated with a selected biodegradable color in accordance with the dimension of said anchor bolts receivable therein.

3. Apparatus according to claim 2, wherein:

said strips and said segments each comprise partly severed portions of a packaging container.

4. Apparatus according to claim 1, wherein:

said segments include markings indicative of the placement thereof on said concrete form.

5. Apparatus according to claim 4, wherein:

said strips and said segments are each coated with a selected biodegradable color in accordance with the dimension of said anchor bolts receivable therein.

6. Apparatus according to claim 5, wherein:

said strips and said segments each comprise partly severed portions of a packaging container.

7. A biodegradable assembly useful in suspending anchor bolts into a poured concrete form 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 plurality of longitudinally spaced openings of generally equal size aligned with corresponding openings on the other ones of said overlying segments for receipt of the shank of said anchor bolt in the common interior thereof; and

a conical retainer formed of a biodegradable material and conformed to engage the shank end of said anchor bolt in the interior thereof.

8. Apparatus according to claim 7, wherein:

said retainers and said segments are each coated with a selected biodegradable color in accordance with the dimension of said anchor bolts receivable therein.

9. Apparatus according to claim 8, wherein:

said segments each comprise partly severed portions of a packaging container.

10. Apparatus according to claim 7, wherein:

said segments include markings indicative of the placement thereof on said concrete form.

11. Apparatus according to claim 10, wherein:

said retainers and said segments are each coated with a selected biodegradable color in accordance with the dimension of said anchor bolts receivable therein.

12. Apparatus according to claim 11, wherein:

said segments each comprise partly severed portions of a packaging container.

13. A method for converting packaging defined by a plurality of corrugated panels into a suspension assembly conformed to extend from the edges of a concrete form to suspend an anchor bolt therein, comprising the steps of

folding a selected one of said corrugated cardboard panels into a plurality of overlying segments each having a longitudinal dimension greater than the span across said concrete form to form a bridging suspension thereacross, each said segment further including a plurality of longitudinally spaced openings of a generally equal size aligned with corresponding openings on the other ones of said overlying segments for receipt of the shank of said anchor bolt in the common interior thereof;

and

engaging the end of said anchor bolt to a retainer of a dimension greater than said openings.

14. A method according to claim 13, wherein:

said step of folding said selected one of said corrugated panels includes the further step of partly severing said selected one of said panels to form said overlying segments.

15. A method according to claim 14, wherein:

said step of engaging the end of said anchor bolt includes the further step of partly severing a selected other one of said corrugated panels into a plurality of strips each including a plurality of holes conformed to engage said anchor bolt upon the accordion folding of said strips.

16. A method according to claim 15, wherein:

each said selected one and other panels are coated by a biodegradable coloring.
