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

exact text as granted — not AI-modified
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.  
   
   
       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.    
   
   
       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.    
   
   
       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.  
   
   
       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.
