ABSTRACT:
An elongated flexible form is presented. The elongated flexible form may be shaped to fit the contour of a concrete structure of variable shape and is held in position by a plurality of positioning brackets. The flexible form is made out of a flexible material such as natural or synthetic rubber and may be reinforced by wire, cables, steel belts, nylon cord, ply material or a combination of the same. Each of the positioning brackets has a hollow body portion which is bolted to the flexible form. A stake and wedge are used to hold each bracket in place. Connecting flanges may be used to attach the end of the flexible form to another flexible form or to a metal form. The connecting flanges are bolted to the end of each form and are held together by a fastening device. Another embodiment of the positioning brackets may be bolted to the end of the flexible form and also used for the purpose of attaching the end of the flexible form to another form.
