The invention disclosed herein is remarkable in its simplicity and promises wide commercial application as the labor costs for construction become increasingly prohibitive. The extraordinary absence of nails, screws, bolts, welds or any other fastening device allows these barriers to compete with many conventional barrier systems, such as those employed for fencing, vehicular trailer beds, removable stages, and scale models or toys of all fabrications mentioned plus many more. In this age time is money and the erection speed this barrier system offers may well revolutionize conventional "post and beam" framing. The invention is specifically aimed at eccentric beam loading where barriers must be economically fabricated to withstand hurricane force winds, earthquake reactions, or liquid concrete pressure in a sub-rigid manner. The Fast-Form System will offer insurers building products that will protect their interests for any and all applications. When the barriers disclosed herein are utilized for concrete formwork, contractors will have a new option that embraces standard building products, with barrier fabrication accomplished in half the time of the systems that precede it.
