A plastic forming system designed to save form erection and stripping time needs no nailing, double staking, or form release agents for assembly. Its basic components include 2x4- or 2x6-inch forms, end connectors, and cam lock clamps. The hollow forms are about one-third the weight of wood. Molded plastic connectors stapled into the ends of each form allow workers to snap forms together for setup and unsnap them when stripping. Each form has a dovetail slot that runs the entire length of one side. Reusable cam lock clamps can be inserted anywhere along the slot to coincide with stake locations, even after the form is in place. More
Commercially available form ties have safe tension load ratings of 1,000 to 50,000 pounds or more. More
