Abstract

Disclosed are a concrete dowel placement devices and a method of utilizing the same. A metallic stud is driven, screwed, or otherwise attached to a form. The stud may be a unitary structure, or may be a hollow tube with conventional fastening means such as nails and screws extending through and holding the hollow tube to the form. A cover having an interior compartment substantially equal in diameter to the stud is slidably placed thereon, and a first enclosed area is developed with a plurality of forms. Concrete is poured into the first enclosed area, and upon curing, the form and the stud are removed, leaving the cover embedded in the concrete. A metallic dowel is inserted into the cover, and a second enclosed area is developed with like configured forms. The metallic dowel extends into the second enclosed area. Upon pouring concrete into the second enclosed area, a cold joint is formed between the concrete of the first enclosed area and the concrete of the second enclosed area, supported and braced by the metallic dowel.
