Abstract: A reinforcement support spacer for spacedly positioning one or more concrete reinforcement members from a surface on which concrete is poured. The spacer comprises a support which has at least one recess therein for receiving a reinforcement member. Barbs or tines formed integrally with the support project into the recesses. The barbs or tines on each recess are oriented so as to permit a reinforcement member to be forced past the barbs or tines into the recess but substantially to prevent a reinforcement member from being forced past the barbs or tines out of the recess once a reinforcement member has been inserted into the recess. The support spacers of the present invention permit reinforcement members to be preassembled in spaced relationship to each other and installed as an assembly. The preassembled reinforcement assembly can be lifted onto the surface on which concrete is to be poured, saving on-site labor costs involved in assembling at the point of use.
