摘要：The present invention relates to a method for producing hollow membersmade of concrete or polymer concrete in the shape of bars. To this end, this method usesa mould comprising a plurality of cores as well as an outer mould which laterallysurrounds the cores so as to define a gap and is capable of displacement relative to saidcores. The mould further comprises a lower sleeve which is also capable of displacement,wherein said sleeve comprises a plurality of openings for the cores and is arranged underthe outer mould. A reinforcing cage is placed approximately in the middle of the cavitiesformed between the cores and the outer mould. The material is then fed into the cavitiesand shaken in order to be compacted. The core (1) comprises at its upper surface aplurality of receiving members (8) which open upwardly and in which the reinforcing cage(6) is attached using fixation hooks (7) provided on its upper surface, with a componentextending radially towards the inside. The reinforcing cage is biased against the core (1)by centring pins (9) which are distributed along its periphery with a component extendingradially towards the inside.
