Abstract (en)
[origin: EP0465755A2] The invention relates to a process for the production of one or a plurality of reinforced concrete beams at the same time, a concrete extruding machine for carrying out the process and a reinforced concrete beam produced in accordance with the process. The process is characterised in that the concrete strip which is produced in the first process step forms an upwardly open channel. In the further course of the process, the steel reinforcement is inserted into this channel and the channel is then filled with concrete. By means of this process, it is possible to produce lattice girders with steel reinforcements protruding from the concrete and nevertheless to achieve high strengths. <IMAGE>
