Stay-in-place concrete footing forms

Abstract

A stay-in-place concrete footings form is used for forming a concrete footing between a spaced-apart pair of the stay-in-place concrete footings forms. Each concrete footing form is elongate and has a cavity inside the form. Each form has a pair of elongate sides wherein openings are formed in the elongate sides to permit water to flow into the cavity. Each form has a dovetail pin or dovetail slot formed along the lengthwise extent of both sides of the form. The dovetails permit clamps, having a mating dovetail slot or dovetail pin, to be clamped to the form for anchoring the form to the ground with a stake carried by the clamps.

1 . A stay-in-place concrete footings form, wherein a concrete footing can be formed between a spaced-apart pair of said stay-in-place concrete footings forms, which comprises: 
 an elongate, hollow concrete footings form having a cavity inside said form, having a pair of elongate sides wherein openings are formed in said elongate sides to permit water to flow into the cavity;    said form having a dovetail pin or dovetail slot formed along the lengthwise extent of both sides of said form, said dovetails permitting clamps having a mating dovetail slot or dovetail pin for clamping to said form for anchoring said form to the ground with a stake carried by said clamps.    
   
   
       2 . The concrete footings form of  claim 1 , which has dovetail slots form along its lengthwise extent and said claims have mating dovetail pins.  
   
   
       3 . The concrete footings form of  claim 1 , which has dovetail pins form along its lengthwise extent and said claims have mating dovetail slots.  
   
   
       4 . The concrete footings form of  claim 1 , wherein one side has a dovetail slot and the other side has a dovetail pin.  
   
   
       5 . The concrete footings form of  claim 1 , which is formed from plastic.  
   
   
       6 . The concrete footings form of  claim 1 , wherein the top and bottom also have a dovetail pin or dovetail slot formed along its lengthwise extent.  
   
   
       7 . The concrete footings form of  claim 6 , wherein a pair of said forms are stacked atop each other and a mating spline connects said forms together.  
   
   
       8 . The concrete footings form of  claim 6 , wherein a fabric sheet is secured to the top dovetail pin or dovetail slot with a mating spline.  
   
   
       9 . A pair of the concrete footings forms of  claim 6  spaced apart with said secured fabric sheet therebetween.  
   
   
       10 . The concrete footings form of  claim 1 , having a rebar clip secured to said dovetail tip or dovetail slot.  
   
   
       11 . The concrete footings form of  claim 10 , wherein said rebar clip is formed from one or more of plastic or metal.  
   
   
       12 . A concrete footer having the stay-in-place concrete footings form of  claim 1  affixed thereto.  
   
   
       13 . A concrete footer having the stay-in-place concrete footings form of  claim 5  affixed thereto.  
   
   
       14 . A concrete footer having the stay-in-place concrete footings form of  claim 6  affixed thereto.  
   
   
       15 . A concrete footer having the stay-in-place concrete footings form of  claim 8  affixed thereto.  
   
   
       16 . A concrete footer having the stay-in-place concrete footings form of  claim 10  affixed thereto.
