Abstract: The reusable concrete form device especially provides for extreme portability due to light weight, easily assembled components, and tools used repetitively in the application of the forms, flexible forms, braces, and pegs of the device. The device further provides for exact positioning and for maintaining that positioning until desired removal. The sliding dovetail joints of the forms and braces provide this feature. The pegs are located into a surface such as ground, then selectively locked in position relative to each brace via pivot head lock screws disposed within each brace. The headed pegs removably pass through chambers within the braces and are locked in position via pivot headed lock screws. Concrete poured is thereby poured exactly as needed. Joiners with tails are used to also form sliding dovetail joints and to joint forms and flexible forms together.

Abstract: A foundation structure comprises a plurality of light metal parts which assemble and secure in place prior to placement of foundation in situ concrete. Assemblage is supported by coarsely threaded rods which screw directly into earth and attach to parts by various methods.

Abstract: A concrete forming device made from plastic components which can be assembled in the location of use to form a desired shape and fastened to the ground with steel stakes driven through brackets attached to components. After use, the stakes are removed and the components disassembled for use elsewhere. Desirably, the components are formed from fiberglass reinforced resins and additives of a type which impart a surface to the components of such a nature as to have little tendency to adhere to the concrete. This makes it easy to remove the components and to reuse them without cleaning. The components are constructed with suitable adaptors and couplers so that assembly can be accomplished by merely inserting male parts into female parts in a slip fit relationship. Both straight and curved shapes can be formed, as well as shapes that have both straight and curved elements.
