Abstract

Various embodiments of the present disclosure provide a load transfer plate and load transfer plate pocket that co-act to transfer vertical or substantially vertical loads from one concrete slab to the adjacent slab in an enhanced manner by optimizing the positions of the load transfer plate relative to the adjacent concrete slabs for load transfers between the adjacent concrete slabs.

First claim

The invention is claimed as follows:

1. A load transfer plate pocket configured to receive a load transfer plate for transferring loads across a joint between a first cast-in-place concrete slab and a second cast-in-place concrete slab, the load transfer plate pocket comprising:
an attachment wall defining a load transfer plate receiving slot; and
a generally triangular shaped body extending from the attachment wall, the body including:
(a) a generally triangular upper wall;
(b) a generally triangular lower wall, said lower wall spaced apart from the upper wall such that the load transfer plate can freely move between the lower wall and the upper wall;
(c) a first side wall connected to the upper wall and to the lower wall;
(d) a second side wall connected to the upper wall and to the lower wall;
(e) a first load transfer plate positioner extending from the first side wall;
(f) a second load transfer plate positioner extending from the second side wall;
(g) a centering third load transfer plate positioner extending from the first side wall and configured to engage a first tip of the load transfer plate that partially defines a widest area of the load transfer plate; and
(h) a centering fourth load transfer plate positioner extending from the second side wall and configured to engage a second tip of the load transfer plate that partially defines the widest area of the load transfer plate,
wherein the generally triangular shaped body is configured and sized such that the load transfer plate is positionable in the load transfer plate pocket beyond a center line of the load transfer plate when the centering third load transfer plate positioner and the centering fourth load transfer plate positioner engage the first and second tips of the load transfer plate.

2. The load transfer plate pocket of claim 1 , which includes:
(i) a fifth load transfer plate positioner extending from the first side wall; and
(j) a sixth load transfer plate positioner extending from the second side wall.

3. The load transfer plate pocket of claim 1 , which includes:
(i) a first load transfer plate engager connected to the first load transfer plate positioner; and
(j) a second load transfer plate engager connected to the second load transfer plate positioner.

4. The load transfer plate pocket of claim 3 , wherein the first load transfer plate engager is connected to the second load transfer plate engager.

5. The load transfer plate pocket of claim 3 , wherein the first load transfer plate engager is connected to the second load transfer plate engager at a substantially perpendicular angle.

6. The load transfer plate pocket of claim 3 , wherein the first load transfer plate engager extends substantially parallel to the first side wall.

7. The load transfer plate pocket of claim 6 , wherein the second load transfer plate engager extends substantially parallel to the second side wall.

8. The load transfer plate pocket of claim 3 , wherein the first load transfer plate engager is configured to engage a first side edge of the load transfer plate.

9. The load transfer plate pocket of claim 8 , wherein the second load transfer plate engager is configured to engage a second side edge of the load transfer plate.

10. The load transfer plate pocket of claim 1 , wherein the generally triangular shaped body is configured and sized such that the load transfer plate is positionable in the load transfer plate pocket beyond the widest area of the load transfer plate at installation.

11. A load transfer plate pocket configured to receive a load transfer plate for transferring loads across a joint between a first cast-in-place concrete slab and a second cast-in-place concrete slab, the load transfer plate pocket comprising:
an attachment wall defining a load transfer plate receiving slot; and
a generally triangular shaped body extending from the attachment wall, the body including:
(a) a generally triangular upper wall;
(b) a generally triangular lower wall, said lower wall spaced apart from the upper wall such that the load transfer plate can freely move between the lower wall and the upper wall;
(c) a first side wall connected to the upper wall and to the lower wall;
(d) a second side wall connected to the upper wall and to the lower wall;
(e) a first centering load transfer plate positioner extending from the first side wall and configured to engage the load transfer plate adjacent to a first tip of the load transfer plate that partially defines a widest area of the load transfer plate; and
(f) a second centering load transfer plate positioner extending from the second side wall and configured to engage the load transfer plate adjacent to a second tip of the load transfer plate that partially defines the widest area of the load transfer plate.

12. The load transfer plate pocket of claim 11 , which includes:
(e) a first load transfer plate positioner extending from the first side wall; and
(f) a second load transfer plate positioner extending from the second side wall.

13. The load transfer plate pocket of claim 11 , wherein the generally triangular shaped body is configured and sized such that the load transfer plate is positionable in the load transfer plate pocket beyond the widest area of the load transfer plate at installation.
