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 . Apparatus for forming concrete comprising a form having a slot configured to closely receive a plate, wherein said slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which said slot receives the plate.  
   
   
       2 . 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 a plate.  
   
   
       3 . Apparatus of  claim 1 , wherein said form has a back surface, a top surface and a chamfer interposed therebetween defining an angle relative to said top surface ranging from 10° to 89°.  
   
   
       4 . Apparatus of  claim 1 , further comprising a release layer on said form.  
   
   
       5 . Apparatus of  claim 4 , wherein said release layer is constructed of phenolic paper, kraft paper, acrylic, latex, melamine, Formica®, foil, oil, high density overlay, metal or combinations thereof.  
   
   
       6 . Apparatus of  claim 1 , wherein said form is constructed of oriented strand board, dimensional lumber, particle board, metal, plastic, cardboard, fiber board, polyurethane foam, Styrofoam® or combinations thereof.  
   
   
       7 . Apparatus of  claim 1 , wherein said form has a width ranging from 0.125 to 3.000 inches.  
   
   
       8 . Apparatus of  claim 1 , wherein said form has a top surface width ranging from 0.125 to 0.875 inch.
