Abstract

1359627 Moulding concerte ties CONCRETE INDUSTRIES (MONIER) Ltd 11 Oct 1972 [27 Oct 1971] 46761/72 Heading B5A Concrete railway sleepers 58 cast with reinforcing wires 21 and rail support inserts 41 in a multi-cavity mould 32 are removed therefrom by inverting the mould 32 about the pivot bar 49 of a frame 48 (see also Fig. 7) releasably holding the mould 32 to rails 10 by pivotal claws 51. The latter allow the mould to slide along the rails 10 when the tension applied to the wires 21 by rams (28, Fig. 3) during moulding is released. The mould 32 may be inverted by a slewing crane (16, Fig. 5) via a cable 56 attached to apertured lugs 55 on the mould 32. During inversion the sleepers 58 are retained within the mould 32 by pins passing through apertures in the inserts 41. The removal of the sleepers 58 may be facilitated by spraying the moulds with oil prior to casting and by shaking and heating the mould 32 after iversion. The sleepers may be collected by a fork-lift truck (60, Fig. 5). The wires 21 may be positioned within the mould 32 by spacers (36-38, 40) placed between the ends of adjacent, aligned multi-cavity moulds (Figs. 1-3). Following casting, an abrasive saw may be used to sever the wires 21 between adjacent multi-cavity moulds. The mould 32 may be filled by a movable hopper (42, Fig. 4) provided with vibrators (44) and a screed plate (43). The concrete may be formed from portland cement, aggregate, sand and water.
