Concrete forms

Abstract

Moisture resistant foundation footing form sections constructed from corrugated plastic are disclosed. Supports for holding sections of reinforcing bar, and connecting the side walls of the form sections are included. The form sections can be secured in position with stakes, and leveling devices for leveling the form once it is secured in position are disclosed. The form sections disclosed herein can be reused, but they do not attract insects and therefore they do not have to be removed from finished foundation footings.

1 . A form section comprising:
 a. a plurality of anchoring devices;   b. a plurality of leveling devices, wherein the leveling devices are movable along the anchoring devices; and   c. a pair of substantially planar side walls, each side wall having a long axis, a first end, a second end, an interior surface an exterior surface, a top edge, and a bottom edge.   whereby anchoring devices anchor the side walls in a substrate and the leveling devices are movable along the anchoring devices to support the side walls at the desired level.   
   
   
       2 . A form section comprising:
 a. a plurality of stakes;   b. a plurality of leveling discs; and   c. a pair of substantially planar side walls.   whereby anchoring devices anchor the side walls in a substrate and the leveling devices are movable along the anchoring devices to support the side walls at the desired level.   
   
   
       3 . The form section of  claim 2 , wherein the side walls are made from corrugated plastic having spaced, integral interconnecting ribs between two facing sheets of plastic, each side wall having a long axis, a first end, a second end, an interior surface an exterior surface, a top edge, and a bottom edge; wherein the side walls are constructed such that the channels created by the integral interconnecting ribs are open at the top edge and the bottom edge of the side walls, whereby the channels are sized to allow the stakes to be inserted and anchor the sidewalls in a substrate. 
   
   
       4 . The form section of  claim 3 , wherein the stakes are made from plastic. 
   
   
       5 . The form section of  claim 3 , wherein the leveling disc is made from a sheet metal ring with leaves extending towards the center of the ring to form an aperture, wherein the leaves also extend in a direction below the plane of the ring whereby the level disc is adjustable at different positions along the length of the stake. 
   
   
       6 . The form section of  claim 3 , wherein a plurality of side walls can be connected end to end by a clip. 
   
   
       7 . The clip of  claim 6 , wherein the is made of plastic. 
   
   
       8 . The clip of  claim 6 , wherein the clip is made of metal. 
   
   
       9 . The method for creating a foundation footing form comprising the steps of:
 a. preparing a substrate at a location where a foundation footing is desired such that it comprises at least one roughly level surface;   b. selecting the appropriate number of form sections, the sections having a pair of substantially planar side walls made from corrugated plastic having spaced, integral interconnecting ribs between two facing sheets of plastic, the side walls being constructed such that the channels created by the integral interconnecting ribs are open at the top edge and the bottom edge of the side walls;   securing the side walls in a desired location using stakes inserted through channels in the side walls whereby the stakes anchor the side walls in the substrate;   d. securing side walls end to end to one another;   e. positioning the side walls to the desired level by resting the side walls on leveling discs when the leveling discs are attached to stakes; and   f. pouring concrete into the form.   
   
   
       10 . The method according to  claim 9 , wherein the means for ensuring the form section is level is by attaching leveling discs to the stakes at the desired height with the leaves of the leveling discs extending toward the substrate. 
   
   
       11 . The method according to  claim 9 , wherein the means for securing the side walls end to end to one another is by using clips.
