Abstract
The machine precasts reinforced concrete beams of double inverted 'T' section and with webs notched at regular longitudinal intervals. The notches locate transverse reinforcing bars. The machine rotates -the beam mould (1, 54) about its longitudinal axis and has laterally sliding notch-formers (15) which are displaced by jacks (16). The notch formers (15) may be mounted on a longerons (14) each side of the mould enter openings (13) in the mould sidewall, and are shaped (15a) to accommodate continuous longitudinal beam reinforcement (51). Each end of the mould may be mounted on a stub-axle which projects from the end walls of a supporting rail-guided wagon.
