Concrete wood form

Abstract

An improved form construction enables wooden planks to be secured together with a novel clamp member when pouring various concrete structures. The novel clamp member has an L shaped body with the lower leg of the clamp member physically supporting the wooden plank while the upper leg of said clamp member is fastened to an already fixed retaining stake adjoining the clamp member. A pair of these clamp members can also be physically joined together in the present form construction to further position the supported plank members in a right angle orientation.

1 . A removable L shaped clamp member to temporarily secure a wooden plank in place, the lower leg of said clamp member providing physically support of said wooden plank and the upper leg of said clamp member including fastening means to physically join said clamp member to an already fixed retaining stake.  
   
   
       2 . The clamp member of  claim 1  wherein the lower leg of said clamp member includes a raised outer edge keeping the supported wooden plank fixed in place.  
   
   
       3 . The clamp member of  claim 1  wherein the upper leg of said clamp member includes a laterally extending projection.  
   
   
       4 . The clamp member of  claim 1  wherein the lower leg of said clamp member includes at least one inner pointed spike.  
   
   
       5 . The clamp member of  claim 1  wherein the upper leg of said clamp member includes at least one inner pointed spike.  
   
   
       6 . The clamp member of  claim 1  wherein both upper and lower legs of said clamp member include inner pointed spikes.  
   
   
       7 . The clamp member of  claim 1  wherein the fixed retaining stake to which said clamp member is physically joined includes nail openings.  
   
   
       8 . The clamp member of  claim 1  wherein the fastening means of said clamp member includes nail openings.  
   
   
       9 . The clamp member of  claim 1  wherein the fixed retaining stake and the fastening means of said clamp member both include nail openings.  
   
   
       10 . The clamp member of  claim 1  wherein a removable clip further resists movement of said clamp member after joinder to said already fixed retaining stake.  
   
   
       11 . The clamp member of  claim 9  wherein joinder of said clamp member to said already fixed retaining stake is carried out with a conventional metal nail being inserted into the nail openings.  
   
   
       12 . The clamp member of  claim 9  wherein joinder of said clamp member to said already fixed retaining stake is carried out with threaded screw means included in the fastening means of said clamp member.  
   
   
       13 . The clamp member of  claim 1  wherein joinder of said clamp member to said already fixed retaining stake is carried out with cam locking means included in the fastening means of said clamp member.  
   
   
       14 . The clamp member of  claim 1  wherein the fastening means of said clamp member includes a vertically extending hollow cylinder in which the already fixed retaining stake is lodged.  
   
   
       15 . The clamp member of  claim 1  wherein the lower leg of said clamp member provides a horizontal shelf physically supporting said wooden plank.
