Method of Making an Apparatus for Forming Concrete

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.

1 . Method of making an apparatus for forming concrete comprising: 
 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.    
   
   
       2 . Method of  claim 1 , wherein the slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which the slot receives a plate.  
   
   
       3 . Method of  claim 1 , wherein each of the plurality of forms has a side surface and a back surface with which the annular surfaces define proximal intersections and distal intersections configured to contact corresponding proximal portions and distal portions of a plate.  
   
   
       4 . Method of  claim 1 , wherein each of the plurality of forms has a back surface and a top surface, further comprising cutting a chamfer between the back surface and the top surface in each of the plurality of forms.
