Plate concrete dowel system
First Claim
1. A disc dowel system interposed between adjacent first and second concrete pours defining a pour joint therebetween, the disc dowel system comprising:
- a dowel plate having an orthogonal shape and defining an embedded portion and a slidable portion, the dowel plate having a pair of opposing side edges;
a pocket former disposed within the first pour and having a laterally extending interior compartment with an open generally straight side, a pair of opposing compartment sides and a compartment end, the straight side being aligned with the pour joint; and
a rib insert configured to be removably insertable into the pocket former and comprising a spaced pair of side members interconnected by a connecting member, each one of the side members being configured to extend along at least a portion of an adjacent one of the compartment sides when the rib insert is installed in the pocket former, each one of the side members including three laterally outwardly extending biasing members sized and configured to bear against a side edge of the dowel plate, the biasing members being disposed in spaced relation to one another and extending along a direction toward the connecting member;
wherein the embedded portion is rigidly encapsulated within the second pour and the slidable portion is slidably disposed within the pocket former, the pair of opposing side edges being positioned parallel to the pair of opposing compartment sides, the side members being configured to resiliently deflect such that the dowel plate permits relative horizontal movement of the first and second pours while resisting relative vertical movement thereof.

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 pocket former having a rib insert disposable therewithin for engaging the sides of a dowel plate. The pocket former has a vertical base flange with a pair of fastener-receiving bosses for securing the pocket former 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 and is positioned within the first pour. 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.

9. A rib insert for a pocket former of a disc dowel system adapted for installing an orthogonally shaped dowel plate within a pour joint between adjacent first and second concrete pours, the pour joint being formed by a concrete form, the dowel plate having a generally orthogonal shape with an embedded portion and a slidable portion, the dowel plate having a pair of opposing side edges, the pair of opposing side edges being positioned parallel to the pair of opposing compartment sides, the pocket former having an open, straight side, a pair of opposing compartment sides and a compartment end, the rib insert comprising:
-
a spaced pair of side members sized and configured to extend along at least a portion of an adjacent one of the compartment sides when the rib insert is installed in the pocket former, the side members being configured to resiliently deflect in response to direct engagement with side edges of the dowel plate; and a connecting member interconnecting the side members and being configured to resiliently deflect in response to direct engagement with an end edge of the dowel plate, the connecting member including a deflection member extending laterally outwardly therefrom and being configured to bear against the end edge of the dowel plate when installed within the pocket former. - View Dependent Claims (10, 11, 12, 13)
