Abstract

An embodiment configured according to principles of the invention of an apparatus for transferring a load between a first concrete slab and a second concrete slab, defining a joint, includes a plate configured to transfer a load between concrete slabs, a form having a slot configured to closely receive a first portion of the plate prior to pouring concrete thereon, and a sheath configured to receive a second portion of the plate. An embodiment configured according to principles of the invention of a method of forming concrete includes providing a plate configured to transfer a load between concrete slabs; providing a form having a slot configured to closely receive a first portion of the plate; positioning the form to receive concrete; inserting the first portion in the slot wherein a second portion of the plate is exposed; pouring a first volume of concrete on the form and the second portion; curing the first volume of concrete and defining a first slab; removing the form from the first slab and exposing the first portion; and disposing a sheath on the first portion. An embodiment configured according to principles of the invention of a method of forming concrete includes providing a plate configured to transfer a load between concrete slabs; providing a form having a slot configured to closely receive a first portion of the plate; positioning the form to receive concrete; inserting the first portion in the slot wherein a second portion of the plate is exposed; disposing a sheath on the second portion; pouring a first volume of concrete on the form and the sheath; and curing the first volume of concrete and defining a first slab. An embodiment configured according to principles of the invention of a method of forming concrete includes providing a form configured to secure a sheath thereto, thereby orienting an exterior of the sheath for contacting concrete when poured thereon; positioning the form to receive concrete; securing the sheath to the form; pouring a first volume of concrete on the form and the exterior; and curing the first volume of concrete and defining a first slab.

Claims

1. Apparatus for forming concrete comprising:

a plate configured to transfer a load between concrete slabs;

a form having a slot configured to closely receive a first portion of said plate prior to pouring concrete thereon; and

a sheath configured to receive a second portion of said plate;

wherein said slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which said slot receives said plate.

2. Apparatus of claim 1, wherein, prior to pouring concrete thereon, said sheath receives said plate.

17. Apparatus of claim 1, wherein said form has a side surface and a back surface with which said annular surfaces define proximal intersections and distal intersections configured to contact corresponding proximal portions and distal portions of said plate.

3. Apparatus for forming concrete comprising:

a sheath having an interior configured to receive a first portion of a plate, configured to transfer a load between concrete slabs, and an exterior for contacting concrete;

a form configured to secure said sheath thereto, thereby orienting said exterior so that concrete poured thereon contacts only said form and said exterior.

4. Apparatus of claim 3, wherein said form has a slot configured to closely receive a portion of said sheath.

5. Apparatus of claim 4, wherein:

said sheath further comprises a mounting plate; and

said slot is configured to closely receive said mounting plate.

6. Apparatus of claim 3, wherein said form is configured to secure a plurality of sheaths thereto at pre-determined intervals.

7. Apparatus of claim 3, wherein said form has pre-drilled holes for receiving fasteners for fixing said sheath to said form.

8. Apparatus of claim 3, further comprising a plate configured to transfer a load between concrete slabs and to be received in said interior.

9. Method of forming concrete comprising:

providing a plate configured to transfer a load between concrete slabs;

providing a form having a slot configured to closely receive a first portion of the plate;

positioning the form to receive concrete;

inserting the first portion in the slot wherein a second portion of the plate is exposed;

pouring a first volume of concrete on the form and the second portion;

curing the first volume of concrete and defining a first slab;

removing the form from the first slab and exposing the first portion; and

disposing a sheath on the first portion.

10. Method of claim 9, further comprising:

pouring a second volume of concrete adjacent to the first slab and on the sheath; and

curing the second volume of concrete and defining a second slab.

18. Method of claim 9, wherein the slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which the slot receives the plate.

11. Method of forming concrete comprising:

providing a plate configured to transfer a load between concrete slabs;

providing a form having a slot configured to closely receive a first portion of the plate;

wherein the slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which the slot receives the plate;

positioning the form to receive concrete;

inserting the first portion in the slot wherein a second portion of the plate is exposed;

disposing a sheath on the second portion;

pouring a first volume of concrete on the form and the sheath; and

curing the first volume of concrete and defining a first slab.

12. Method of claim 11, further comprising:

removing the form from the first slab and exposing the first portion;

pouring a second volume of concrete adjacent to the first slab and on the first portion; and

curing the second volume of concrete and defining a second slab.

13. Method of forming concrete comprising:

providing a form configured to secure a sheath thereto, thereby orienting an exterior of the sheath for contacting concrete when poured thereon;

positioning the form to receive concrete;

securing the sheath to the form;

pouring a first volume of concrete on the form and the exterior; and

curing the first volume of concrete and defining a first slab.

14. Method of claim 13, wherein the form has a slot for closely receiving a portion of the sheath, said securing comprising inserting the portion in the slot.

15. Method of claim 13, wherein the form has pre-drilled holes for receiving fasteners for fixing the portion to the form, said securing comprising fixing the portion on the form.

16. Method of claim 13, further comprising:

removing the form from the first slab;

disposing in the sheath a first portion of a plate configured to transfer a load between concrete slabs;

pouring a second volume of concrete adjacent to the first slab and on a second portion of the plate; and

curing the second volume of concrete and defining a second slab.
