Abstract

A support structure for retaining a reinforcing bar (“rebar”). Such a structure includes a rebar engaging portion, where the rebar engaging portion includes a receptacle. The receptacle includes a channel sized to receive the rebar, where the channel includes a first portion and a bar retaining portion defined by sidewalls that extend radially outward from a first end to a second end. The retaining features are disposed on the walls of the channel, where the sidewalls are configured to spread so that the rebar passes the retaining features and rests in the bar retaining portion as the rebar moves down the channel. Additionally, the support structure includes a support portion supporting the rebar engaging portion, where the support portion includes a plurality of legs which project outward from a central axis. In addition, the support structure includes a base configured to distribute weight of the support structure.
