DISPOSITIF DE PREFABRICATION DE PIECES EN MATIERE DURCISSABLE, NOTAMMENT EN BETON

摘要

The precasting bed produces concrete beams, using trestles (3) to support longitudinal beams (2) to which a mould (1) is attached. The beam and mould assembly is interchangeable and the trestles are mounted on vibrators (4). Elastic attachment of the beam to the trestle is made by suckers (6) connected to a vacuum source. A laminar bearing (7) in rubber may interpose the trestles and the beams sound proofing may be provided by cladding of insulating panels (8) with elastic joints.
