The forming apparatus herein is horizontally elongated and highly flexible. This apparatus is constructed in various lengths and widths depending on the user's requirements. Hereon vertical tabs (11) are welded to the outside of the form at pre-determined intervals to support angled iron (12) to achieve horizontally straight and sturdy forming. Whereby removing said angled iron (12), you are able to achieve any desired curve, whether concave or convex. A manually adjustable apparatus (10), consisting of two sections of tube steel, one having a larger inside diameter than the outside diameter of the other, wherein assembled are slidable for horizontal adjusting of the said forms. Hereon, welded to the said adjuster, a vertical round tube having a set screw within, holds a vertical steel rod. Herein, the steel rod is driven into the earth for stability and vertical adjusting is achieved by means of the set screw. Hereon each length of form, end plates are welded at ninety degree angles, whereby two sections can be assembled by means of male and female connection. By means of each sections ability to connect, these forms can be assembled and dismantled for transportation from job site to job site. |
