A compactible inner form assembly for forming concrete building shafts
Abstract An inner form assembly for forming concrete building shafts has a quadrant of boards and corner posts therebetween. Each corner post has angled interface surfaces converging towards exposed orthogonal skin surfaces. The boards have respective angled interface surfaces meeting respective angled interface surfaces of the corner posts so that the boards are held orthogonally by the corner posts. The angled interface surfaces of the corner posts and the boards slidably bear against each other and mechanically interlock with catches sliding along slots so that the boards move in together to form a compacted cross section configuration when the corner posts rise with respect to the boards and the boards move out to form an expanded cross section configuration when the corner posts fall with respect to the boards and wherein the orthogonal skin surfaces come into alignment with respective skin surfaces of adjacent boards.
