2x4 coupling plate

Abstract

The 2×4 Coupling Plate allows two boards to be reversibly coupled so that the lengths of the two boards may be added together. The coupling plates allows both boards to be separated without damaging them. This device allows a concrete fabricator to assembly two 2×4 boards together and hold them together to form a structure to contain liquid concrete. Once the concrete is set, the installer removes the two boards from the coupling plate so that the boards can be used on another concrete form.

I hereby claim: 
     
         1 . A concrete form plate, or bracket, comprising:
 a plate having a substantially channel-shaped body dimensioned to slidably receive two lumber boards when in use to form a concrete form,   wherein the channel-shaped body comprises a flat plate, two sidewalls, and two rims;   wherein each of the two sidewalls connects a length of the flat plate to one of the two rims;   wherein each of the two rims includes one or more holes, and   wherein each of the one or more holes is formed to receive a nail, or other securing means, when in use to form a concrete form.   
     
     
         2 . The device of  claim 1 , wherein the lumber boards are 2×4s. 
     
     
         3 . The device of  claim 1 , wherein the lumber boards are 1×4s. 
     
     
         4 . The device of  claim 1 , wherein the channel-shaped body is composed of 26 gauge steel. 
     
     
         5 . The device of  claim 1 , wherein the channel-shaped body is at least 16 inches in length. 
     
     
         6 . The device of  claim 5 , wherein the channel-shaped body is less than 20 inches in length. 
     
     
         7 . The device of  claim 6 , wherein the channel-shaped body has a width of 3 and ⅝ inches. 
     
     
         8 . The device of  claim 7 , wherein each of the two sidewalls has a width of ⅞ inches.
