Method for Tool Free Rebar TieA method for securing rebar prior to concrete pour. The method consists of tying by hand, in a series of unique steps, a piece of 16 gauge steel wire with 2 inch loops on either end around the rebar at joints where the rebar sections come together. This method is used in place of a mechanical system as required in prior art, and requires no tools or other devices. Application of the method is up to 4 times faster and twice as strong when compared to the methods currently in use, providing substantial savings in manpower and time on any construction job where reinforced concrete is required. Being entirely manipulated by hand, this method produces an extraordinary and unexpected result over the prior art.

At least one bar clip may be movably mounted on the support rod. An orientation of the at least one bar clip on the support rod is adjustable, and a position of the at least one bar clip on the support rod is adjustable.

A rebar set-up bar used to construct a rebar grid that provides reinforcement for a concrete wall or structure. The set-up bar is vertically positioned in the grid and includes a metal or steel rod having a plurality of supports. The supports are attached to the elongated rod at intervals and are adapted to receive horizontal rebars therein.
