Abstract
A disc dowel system is interposed between adjacent first and second concrete pours defining a pour joint therebetween. The disc dowel system comprises a positioner bracket, a pocket former and an orthogonally shaped dowel plate. The positioner bracket has a horizontal plate portion and a vertical base flange that is rigidly attachable to a concrete form. The pocket former has a horizontally extending interior compartment with an open straight side that is aligned with the pour joint. The pocket former is positioned within the first pour by the positioner bracket. The dowel plate has an orthogonal shape with an embedded portion and a slidable portion. The embedded portion is rigidly encapsulated within the second pour. The slidable portion is slidably disposed within the pocket former such that the dowel plate permits relative horizontal movement of the first and second pours while restricting relative vertical movement thereof.
