On-grade plates for joints between on-grade concrete slabs
First Claim
1. An on-grade joint-stability system for substantially restricting relative vertical movement of on-grade concrete-slab portions that meet at a joint that does not require load transfer, the system comprising:
- a first on-grade concrete-slab portion;
a second on-grade concrete-slab portion that meets the first on-grade concrete-slab portion at the joint;
multiple, separate first on-grade plates each having a first portion and a second portion, the first portion of each first on-grade plate being positioned underneath, and connected to, in opposition to vertical separation from, the first concrete-slab portion, and the second portion of each first on-grade plate being positioned underneath the second concrete-slab portion; and
multiple, separate second on-grade plates each having a first portion and a second portion, the first portion of each second on-grade plate being positioned underneath the first concrete-slab portion, and the second portion of each second on-grade plate being positioned underneath, and connected to, in opposition to vertical separation from, the second concrete-slab portion;
the first and second on-grade plates having portions, positions and connections as described such that through such portions, positions and connections the first and second on-grade plates substantially restrict relative vertical movement of the first and second on-grade concrete-slab portions that would otherwise result in a height differential across the joint between the first and second on-grade concrete-slab portions;
wherein a substantial quantity of the first and second on-grade plates are tapered such that such plates each have a relatively wider end and a relatively narrower end, and adjacent the joint, have a portion with a gradually decreasing width.

Abstract
Embodiments of the invention relate to an on-grade joint-stability system for on-grade concrete slabs. Embodiments of the system may include: a first on-grade concrete-slab portion; a second on-grade concrete-slab portion that is separated from the first on-grade concrete-slab portion by a joint; a first on-grade plate having a first portion and a second portion, the first portion of the first on-grade plate being positioned underneath, and connected to, the first concrete-slab portion, and the second portion of the first on-grade plate being positioned underneath the second concrete-slab portion; and a second on-grade plate having a first portion and a second portion, the first portion of the second on-grade plate being positioned underneath the first concrete-slab portion, and the second portion of the second on-grade plate being positioned underneath, and connected to, the second concrete-slab portion, such that height differentials across the joint are substantially prevented.

11. A method of stabilizing a joint for substantially restricting relative vertical movement of on-grade concrete slab portions that meet at a joint that does not require load transfer, the method comprising:
-
establishing a positive connection between first portions of multiple, separate first on-grade plates and a first portion of an on-grade concrete slab, in opposition to vertical separation therefrom, wherein second portions of the first on-grade plates are positioned underneath a second portion of the on-grade concrete slab that meets the first portion of the on-grade concrete slab at a joint; and establishing a positive connection between second portions of multiple, separate second on-grade plates and the second portion of the on-grade concrete slab, in opposition to vertical separation therefrom, wherein the first portions of the second on-grade plates are positioned underneath the first portion of the on-grade concrete slab; the establishment of the connections and positions as described being such that through such connections and positions, the first and second on-grade plates substantially prevent height differentials across the joint from occurring; and establishing the connections and positions as described with a substantial quantity of the first and second on-grade plates being tapered such that such plates each have a relatively wider end and a relatively narrower end, and adjacent the joint, have a portion with a gradually decreasing width. - View Dependent Claims (12, 13, 14, 15, 16)

17. For use in creating an on-grade joint-stability system for substantially restricting relative vertical movement of on-grade concrete-slab portions that meet at a joint that does not require load transfer, the on-grade concrete-slab portions including portions, panels and slabs poured independently of each other and portions poured together as one slab and then separated into portions, panels or slabs, and the on-grade slab portions including a first on-grade concrete-slab portion, and a second on-grade concrete-slab portion that meets the first on-grade concrete-slab portion at the joint, apparatus comprising:
-
multiple, separate first on-grade plates each having a first portion and a second portion, the first portion of the first on-grade plates being positioned underneath, and connected to, in opposition to vertical separation therefrom, the first concrete-slab portion, and the second portion of the first on-grade plates being positioned underneath the second concrete-slab portion; and multiple, separate second on-grade plates each having a first portion and a second portion, the first portion of the second on-grade plates being positioned underneath the first concrete-slab portion, and the second portion of the second on-grade plates being positioned underneath, and connected to, in opposition to vertical separation therefrom, the second concrete-slab portion; the first and second on-grade plates having portions, positions and connections as described such that through such portions, positions and connections the first and second on-grade plates substantially restrict relative vertical movement of the first and second on-grade concrete-slab portions that would otherwise result in a height differential across the joint between the first and second on-grade concrete-slab portions; and wherein a substantial quantity of the first and second on-grade plates are tapered such that the plates each have a relatively wider end and a relatively narrower end, and adjacent the joint, have a portion with a gradually decreasing width. - View Dependent Claims (18)
