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; and
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;
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;
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.

12. A disc dowel system 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 disc dowel system comprising:
-
a pocket former having a laterally extending interior compartment configured to be complementary to the dowel plate, the interior compartment having an open straight side, a pair of opposing compartment sides and a compartment end, the pocket former including a base flange formed on the straight side and having a pair of bosses extending outwardly therefrom adjacent respective ones of the compartment sides, each boss having an aperture extending through the base flange and being adapted to receive a fastener to facilitate mounting of the pocket former to the concrete form; wherein the slidable portion is sized and configured to be complementary to the interior compartment with the straight side generally abutting the base flange during pouring of the first pour prior to removal of the concrete form for subsequent insertion of the slidable portion into the interior compartment and pouring of the second pour to encapsulate the embedded portion therewithin, the pair of opposing side edges being positioned parallel to the pair of opposing compartment sides.

15. A pocket former for a disc dowel system adapted to minimize relative vertical displacement of adjacently disposed concrete slabs, the pocket former comprising:
-
an orthogonally shaped interior compartment having upper and lower outer surfaces and having an open, straight side, a pair of opposing compartment sides and a compartment end, at least one of the upper and lower outer surfaces having at least one stiffener rib disposed thereon and being oriented in angled relation to the compartment sides; a rib insert configured to be removably insertable into the pocket former and 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, each of the side members having at least one biasing member extending toward the compartment end. - View Dependent Claims (16)

17. 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. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method for installing a generally orthogonally shaped dowel plate having a pair of opposing side edges within a pour joint between adjacent first and second concrete pours using a pocket former having an interior compartment with an open, straight side, a pair of opposing compartment sides, a compartment end, the pocket former further including a base flange connected to the straight side and having a pair of bosses extending laterally outwardly therefrom adjacent the compartment sides, each of the bosses having an aperture formed therein, the interior compartment being configured complementary to the dowel plate, the dowel plate defining an embedded portion and a slidable portion, the method comprising the steps of:
-
positioning a concrete form along a desired location of the pour joint; attaching the pocket former to the concrete form by extending fasteners through each of the apertures and into the concrete form such that the base flange is disposed in contact with the concrete form; pouring the first pour such that the pocket former is rigidly encapsulated therewithin; removing the concrete form after the first pour has cured; inserting the slidable portion into the interior compartment, the pair of opposing side edges being positioned parallel to the pair of opposing compartment sides; and pouring the second pour such that the embedded portion is rigidly encapsulated within the second pour and the slidable portion is slidably disposed within the pocket former. - View Dependent Claims (25)
