Abstract

A combined rebar chair and depth gauge supports reinforcing steel within an open-sided mold or form, with controlled spacing from outboard and inboard sides of a resultant formed concrete shell structure, e.g., a concrete shell for a swimming pool. The rebar chair has a broad base seated against a closed side of the form defined by soil or a wooden form structure. At least one gusset projects from the base and carries a support member for receiving and supporting a reinforcing steel bar with predetermined spacing from the form. A rod-shaped depth gauge projects a predetermined distance beyond the support member. In use, the concrete shell structure is formed by spraying concrete material against the form until a free end of the depth gauge is covered, thereby insuring a predetermined minimum spacing between an inboard side of the shell structure and the reinforcing steel supported therein.
