Abstract (en)
[origin: EP0342657A2] The shuttering serves for simultaneously making a set of annular finished elements of different standard sizes. It has concentrically arranged shuttering rings 2 to 6 forming between them shaping spaces which are limited at the lower end by bottom rings 12 to 15 and which are filled from the upper end with a paper concrete. After lifting and turning, the shuttering is deposited on a pallet 39, against which it is firmly pressed by means of a clamping device 44 to 46. The bottom rings 12 to 15 are connected via ejector rods 24 to a setting plate 30 which is displaceable relative to the shuttering rings 2 to 6 by means of a hydraulic setting device 35, in order first to compact the concrete in the shaping spaces and then, after the release of the clamping device, to eject the set of finished elements. <IMAGE>
