摘要:
The invention is concerned with a method and a mould for the casting of large-size concrete objects or elements for compacting the high-viscosity casting mix, the mould (3 or 17) comprising a bottom (8 or 24) and side walls (6,7) as well as, additionally, a deck (9 or 25) for bringing the high-viscosity casting mix present in the mould (3 or 17) mechanically under pressure. According to the invention, repeated parallel dislocations back and forth are produced in the various regional zones of the mechanically pressurized high-viscosity casting mix (1) present in the mould (3 or 17), and in particular in parallel dislocation planes (2) of the casting mix. This is achieved by pivoting two opposite mould (3 or 17) walls (4, 5) or wall portions (20, 21, 22, 23) in synchronism and always in the same direction in relation to each other or in relation to their corresponding portions provided in pairs, which pivoting takes place around shafts (10, 11 or 28, 29) placed at a distance from one another, included in the planes of the said mould walls, and being parallel to each other and to the parallel dislocation planes (2) of the casting mix (1).

The invention is concerned with a method and a mould in continuous slide-casting of large-size concrete objects or corresponding elements for compacting high-viscosity casting mix. The slide-casting mould (33) comprises a bottom plane (34), side walls (38,39) of the mould, as well as means (37) for pressurizing the casting mix mechanically. According to the invention, before the parallel side walls (44, 54) at the outlet end of the slide-casting mould (33), within the casting line concerned, walls or wall portions (40 to 43, 50 to 53) are provided as fitted to each other or to their corresponding portions, provided as pairs, as pivotable always in the same direction around substantially vertical shafts (45 to 49, 55 to 59) included in their planes. The moving parts of the side walls (38, 39) may be displaced in pairs in the lateral direction, relative the casting direction, e.g., by means of cylinder-piston devices (61 to 63). Thereat, repeated parallel dislocations back and forth are produced in the various regional zones of the mechanically pressurized high-viscosity casting mix (35) present in the slide-casting mould (33), and in particular in parallel dislocation planes of casting mix (35) in the mould (33), placed perpendicularly to the longitudinal direction of the casting base.

Method and device for the casting of concrete products either by means of a periodic method or by means of a continuous slide casting method. Into the product, one or several cavities are formed by means of a cavity mandrel (4). The mix is compacted by rotating the cavity mandrel (4) back and forth around its longitudinal axis.
