ABSTRACT:
A chair for supporting, positioning and retaining a concrete reinforcing bar in place at predetermined height in the pouring and construction of concrete slabs or beams at a jobsite wherein the concrete reinforcing bar remains as an integral, strengthening element of the construction. The chair includes a cap with a recessed or slotted upper face for retaining and supporting the concrete reinforcing bar, and a base; the cap (which supports the concrete reinforcing bar) being supported above the base via a stem. Caps and bases of standard size can be supplied to a jobsite, and chairs of varying height readily constructed therefrom at the jobsite by cutting stems of desired length from a concrete reinforcing rod, based on the requirements of slab thickness, or beam depth.
