Abstract
A concrete dowel placement apparatus comprising a base member and an elongate, tubular dowel receiving sheath which is connectible to the base member. The base member comprises an outer sleeve having first and second ends, and an inner sleeve which is disposed within the outer sleeve. Extending between the inner and outer sleeves is at least one reinforcement wall. Extending about the first end of the outer sleeve is a flange portion which defines a generally flat back surface. The inner sleeve defines an aperture which extends from the second end of the outer sleeve to the back surface of the flange portion, and is sized to accommodate a fastener such as a nail to facilitate the attachment of the base member to a concrete form subsequent to the abutment of the back surface of the flange portion thereagainst. The sheath has an open proximal end, a closed distal end, and a hollow interior comportment extending longitudinally therein, with the proximal end being slidably extensible over the outer sleeve such that the outer sleeve resides within the interior compartment.
