Connectors for concrete footer frames

Abstract

A stamped, sheet metal, form connector connects two concrete form boards together in end-to-end abutting relationship in one embodiment. In another embodiment, the connector connects two form boards in overlapping relationship. In a third and fourth embodiment, the connector connects two form boards at an inside and outside corner, respectively. Double headed nails fasten the connector to the form boards, allowing for easy removal without damage to the forms. The connector is inexpensive to manufacture, and is simple and convenient to use.

1 ) A connector for connecting two form boards, used for forming a concrete footing, across a joint between the form boards in fixed relationship, the concrete form boards having an inner surface which confines the concrete poured therein, an upper edge, and an outer surface, said connector comprising: 
 an upper portion which extends across the upper edge of the form boards and spans the joint;    an outer portion, connected to said upper portion, which extends downwardly from said upper portion over a part of said outer surface of the form boards;    and, means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards.    
   
   
       2 ) The connector of  claim 1 , further comprising an inner portion connected to said upper portion, said inner portion extending downwardly from said upper portion over a part of said inner surface of said form boards.  
   
   
       3 ) The connector of  claim 2 , wherein said means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards comprises nails which pass through said upper portion and into said upper edge of said form boards.  
   
   
       4 ) The connector of  claim 2 , wherein said means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards comprises nails which pass through said outer portion and into said outer surface of said form boards.  
   
   
       5 ) The connector of  claim 1 , wherein said means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards comprises a screw having an inner end and an outer end, said inner end threadably engaged in said outer portion and passing therethrough, a plate connected to said screw at said inner end and engaged against said outer surface of said form board, and a T-handle fixed to the outer end of said screw for facilitating turning of said screw.  
   
   
       6 ) The connector of  claim 1 , wherein said outer portion has an opening therein, said opening spanning said joint between said form boards on said outer surface, thereby allowing for accurate placement of said connector across said joint.  
   
   
       7 ) The connector of  claim 2 , wherein said outer portion has an opening therein, said opening spanning said joint between said form boards on said outer surface, thereby allowing for accurate placement of said connector across said joint.  
   
   
       8 ) A connector for connecting two form boards, used for forming a concrete footing, across an outside corner joint between the form boards in fixed relationship, the concrete form boards having an inner surface which confines the concrete poured therein, an upper edge, and an outer surface, said connector comprising: 
 an upper portion which extends across the upper edge of the form boards and spans the joint, said upper portion having two legs formed at right angles to each other;    an outer portion, connected to said upper portion, said outer portion extending downwardly from said upper portion over a part of said outer surface of the form boards, said outer portion having two legs formed at right angle to each other;    and, means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards on both sides of said joint.    
   
   
       9 ) The connector of  claim 8 , wherein said means for fixedly attaching one of said upper portion or said outer portion to said concrete form boards comprises nails which pass through said upper portion and into said upper edge of said form boards.  
   
   
       10 ) A connector for connecting two form boards, used for forming a concrete footing, across an inside corner joint between the form boards in fixed relationship, the concrete form boards having an outer surface which confines the concrete poured therein, an upper edge, and an inner surface, said connector comprising: 
 an upper portion which extends across the upper edge of the form boards and spans the joint, said upper portion having two legs formed at right angles to each other;    an inner portion, connected to said upper portion, said inner portion extending downwardly from said upper portion over a part of said inner surface of the form boards, said inner portion having two legs formed at right angle to each other;    and, means for fixedly attaching one of said upper portion or said inner portion to said concrete form boards on both sides of said joint.    
   
   
       11 ) The connector of  claim 10 , wherein said means for fixedly attaching of said upper portion or said outer portion to said concrete form boards comprises nails which pass through said upper portion and into said upper edge of said form boards.
