Abstract

Various embodiments of the present disclosure provide a cast-in-place concrete slab load transfer and slab connection apparatus and method of employing same.

Claims

1. A concrete slab load transfer and connection apparatus comprising:

a plurality of load transfer dowels;

a basket supporting the load transfer dowels; and

a plurality of slab connection members forming part of or connected to the basket.

2. The concrete slab load transfer and connection apparatus of claim 1, wherein a plurality of the load transfer dowels are positionable at a first contraction joint between and configured for load transfer between a first pair of adjacent concrete slabs.

3. The concrete slab load transfer and connection apparatus of claim 2, wherein a plurality of the load transfer dowels are positionable at a second contraction joint between and for connecting a second pair of adjacent concrete slabs.

4. The concrete slab load transfer and connection apparatus of claim 3, wherein one of the slab connection members is positionable at a third contraction joint between and for connecting one of the first pair of adjacent concrete slabs and one of the second pair of adjacent concrete slabs.

5. The concrete slab load transfer and connection apparatus of claim 4, wherein the first pair of adjacent concrete slabs are longitudinally adjacent concrete slabs in a roadway or a floor, and the second pair of adjacent concrete slabs are longitudinally adjacent concrete slabs in the roadway or the floor.

6. A concrete slab load transfer and connection apparatus comprising:

a plurality of load transfer dowels;

a plurality of baskets supporting the load transfer dowels; and

a plurality of slab connection members connecting the plurality of baskets.

7. The concrete slab load transfer and connection apparatus of claim 6, wherein one of the slab connection members is positionable at a contraction joint between and for connecting adjacent concrete slabs.

8. The concrete slab load transfer and connection apparatus of claim 6, wherein the load transfer dowels are positionable at first and second contraction joints.

9. The concrete slab load transfer and connection apparatus of claim 8, wherein the slab connection members are positionable at third and fourth contraction joints.

10. The concrete slab load transfer and connection apparatus of claim 8, wherein the first and second contraction joints extend transversely in a roadway or a floor, and the third and fourth contraction joints extend longitudinally adjacent concrete slabs in the roadway or the floor.
