Abstract

The stirrup has two legs (7a, 7b) supporting rectangular sliding concrete shutters (10, 11) and has traverse member (7c) which holds a jack (8) which varies shutter spacing and hence the thickness of the cast wall. The shutter climbs a metal bar (5), which is angled to the vertical to produce the conical effect, by means of a second, per perpendicular jack (9). A pair of brackets (12, 13) provide outside and inside working patforms for placing the concrete while lateral support is given to the shutters by further pairs of brackets (14, 15) and (16, 17) which form quadrilaterals which deform as the work moves inwards by articulating about guide wires (20) fixed to the centre of curvature of the work.
