ABSTRACT:
Forms for a cylindrical wall of poured concrete are made of plywood sheets nailed to horizontally-spaced beams, to which are clamped transversely arranged walers. The walers are assembled in strings and the string are in parallel spaced relationship. The walers in a string are hinged together at the sheet-facing side of the walers and at least one of two adjacent waler sections is curved. Screw assemblies are mounted in brackets located at the ends of the walers but on the sides facing away from the sheets, and are operable to push or pull the walers out of alignment so that they can be pulled or pushed into a ring shape and, in so doing, bend the sheets into generally cylindrical shapes. When the sheets are raised on end, with the beams disposed vertically they provide the inside and outside wall forms for receiving concrete, for example, poured between them to form an annular cylindrical wall for a tank or the like.
