Concrete dowel placement apparatus
First Claim
1. A concrete dowel placement apparatus, comprising:
- a base member comprising;
an outer sleeve having first and second ends;
a flange portion extending about the first end of the outer sleeve and defining a front surface, a back surface, and a peripheral edge;
an inner sleeve disposed within the outer sleeve, said inner sleeve defining an aperture which extends longitudinally therethrough to the back surface of the flange portion; and
at least one reinforcement wall extending between the inner and outer sleeves;
a dowel receiving sheath having an open proximal end, a closed distal end, and a hollow interior compartment extending longitudinally therein;
the open proximal end of the sheath being extensible over the outer sleeve such that at least a portion of the outer sleeve resides within the interior compartment.

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 a flange portion which extends about the first end of the outer sleeve and defines front and back surfaces and a peripheral edge. The base member further comprises an inner sleeve which is disposed within the outer sleeve and defines an aperture extending longitudinally therethrough to the back surface of the flange portion. Extending between the inner and outer sleeves is at least one reinforcement wall. The sheath has an open proximal end, a closed distal end, and a hollow interior compartment extending longitudinally therein. The open proximal end of the sheath is extensible over the outer sleeve such that at least a portion of the outer sleeve resides within the interior compartment.

35. A method of extending a dowel rod through a joint between adjacent concrete slabs, comprising the steps of:
-
(a) providing a base member which comprises; (i) an outer sleeve having first and second ends; (ii) a flange portion extending about the first end of the outer sleeve and defining a front surface, a back surface, and a peripheral edge; (iii) an inner sleeve disposed within the outer sleeve, said inner sleeve defining an aperture which extends longitudinally therethrough to the back surface of the flange portion; and (iv) at least one reinforcement wall extending between the inner and outer sleeves; (b) attaching the base member to a concrete form such that the outer sleeve protrudes therefrom; (c) providing a sheath which includes an open proximal end, a closed distal end, and a hollow interior compartment extending longitudinally therein; (d) extending the open proximal end of the sheath over the outer sleeve of the base member such that at least a portion of the outer sleeve resides within the interior compartment; (e) making a first pour of concrete within the concrete form about the sheath; (f) removing the outer sleeve of the base member from within the sheath subsequent to the curing of the first pour; and (g) inserting the dowel rod into the open proximal end of the sheath. - View Dependent Claims (36, 37, 38)
