ABSTRACT:
A holder for use in building construction for holding anchor bolts, rebar, in-concrete plumbing, and the like, in predetermined positions during the pouring of concrete therearound The holder is molded in one piece from a suitable plastic and includes an elongated base plate, the front end which has an end hole therethrough; a sleeve projecting from the base plate over the end bole; elongated first and second re-enforcing side ribs providing from the base plate and connected to the sleeve; an end rib partially wrapped around the sleeve and integrally joining the sleeve and the forward ends of the side ribs where they meet the sleeve; a center rib projecting from the base plate between the side ribs and also connected to the sleeve; webs projecting from the base plate, interconnecting the side and center ribs, and having nail holes therethrough, and preferably also including an end plate. The integration of the ribs and webs with each other and with the base plate, the sleeve and the end plate, in one piece, and out of plastic, provides a light-weight, durable, low-cost holder for the purposes described. A feature of the invention is the molding of the holder out of a brightly colored plastic so that it can be readily seen by construction workers after the concrete has been poured partially covering it An alternative embodiment provides such a holder that can be spread apart for receiving and clamping around anchor bolts, rebar, or similar construction elements.
