1536453 Wall shuttering A C WHITTING 21 April 1976 [22 April 1975] 16153/76 Heading E1S Concrete wall shuttering for, e.g. a building, is supported, at least on one wall face, by a vertically-movable member, e.g. 40, (Fig. 4(a), which is supported in a vertical position by a tube e.g. 44 cast into the wall structure, and which is of a height, or can be extended to a height, which is more than twice the height of the shuttering. In theembodiment of Fig. 3, inner and outer shutters 15, 16 are supported, via a yoke 14, on a double-acting piston-andcylinder device 32, 33 located within an asbestos-cement tube 31 embedded in the first lift of concrete, 17. The shutters are hinged outwards, and raised by the piston, which is raised hydraulically. The shutters are then fixed to the concrete wall, the piston 33 retracted, a further tube 35 erected, the piston and cylinder are then raised again, in turn, and a supporting device placed under the cylinder, after which the second pour of concrete is made. In the embodiment of Fig. 4, climbing jacks 45, 46 and climbing rods 47, 48 are employed, in conjunction with a steel tube 40 having collars 41, 42, and located within an asbestos-cement tube 44. Yoke 14 is raised by the jacks climbing the rods, whereafter the shutters are again fixed to the wall. A yoke 49 supporting the rods, is arranged to be moveable sideways to allow a further asbestoscement tube 50 to be positioned above the tube 44. Tube 40 is then raised by raising rods 47, 48 through the jacks 45 and 46. In the embodiment of Fig. 5, a single, central jack (53) is arranged on a yoke (14), and the vertically movable member (52), similar to tube 40, is modified so that the jack (53) can engage it. The shutters are then raised via the jack, which moves up member (52), which is designed to be split into two parts to allow the positioning of further asbestos-cement tubes (54) to form the vertical hole in the wall.
