Stephen McDonald - Loganville GA, US

International Classification:

E04C003/30

US Classification:

052730100

Abstract:

An apparatus for forming concrete includes a form having a slot configured to closely receive a plate. The slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which the slot receives the plate. A method for forming same includes providing a sheet of form material; disposing a release layer on the sheet; cutting the sheet into a plurality of forms having a predetermined form height; and cutting a slot in each of each of the plurality of forms. Another apparatus for forming concrete includes a plate having a first portion and a second portion. A coating is disposed on the first portion. When disposed in a joint defined by a first volume of concrete and a second volume of concrete, the first volume of concrete adheres only to the coating and the second volume of concrete adheres only to the second portion. A method for forming concrete includes providing a plate having a coated first portion and a second portion; providing a form having a slot configured to closely receive the second portion; inserting the second portion in the slot; positioning the form to receive concrete; pouring a volume of concrete on the form and the first portion; curing the volume of concrete and defining cured concrete; and removing the form from the cured concrete. The plate remains in the cured concrete.

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.
