Patent ID: 8574471

Claim:
A system for creating a form used to make concrete structures comprising: (A) a plurality of panels, each panel having multiple sets of spaced-apart tie apertures, each set of tie apertures being set in a longitudinal orientation upon the panel, each set of tie apertures being spaced apart from one another in a parallel configuration; (B) a plurality of ties, each tie comprising of a body, ends, stop tabs, the body being located between two ends with each end having a locking aperture, the stop tabs being located between the respective end and the body; (C) a plurality of L-shaped brackets, the plurality of L-shaped brackets having top and bottom flanges connected along a common edge in perpendicular orientation to one another, each flange further having a respective set of spaced-apart perforations located along the lengthwise center of the flange; (D) a plurality of locking mechanisms that can attach to the L-shaped brackets by the perforations and can attach to the ties by the locking apertures; wherein two or more ties are located between and perpendicular to at least a pair of panels to hold the panels in spaced-apart, parallel and opposing orientation, the ends of the ties protruding through respective tie apertures and corresponding perforations of plurality of L-shaped brackets located on the outside of the panels, said panels and L-shaped brackets being held in place on the ties by locking mechanisms respectively engaging ends to form an assembled pair of panels, two or more assembled pairs of panels are connected together in tandem by overlaying a first L-shaped bracket upon a portion of one of the L-shaped brackets holding one assembled pair of panels together and upon a portion of one of the L-shaped brackets holding another assembled pair of panels together, the two or more assembled pairs of panels then forming a continuous cavity into which plastic concrete is poured to make a concrete structure.
