摘要

Procedure for the manufacture of continuous concrete plates, for which part of a machine provided with a hopper that, in a controlled manner, poured concrete in pasty state on steel cables stretched longitudinally between a pair of rails, by which the aforementioned machine slides, which is characterized in that said machine, in addition to offering the mentioned features, pushes the concrete that descends from the hopper by means of the concurrence of a series of parallel mechanisms located in battery under it, each one of them being composed of mechanisms referred to by a small hydraulic motor in charge of driving a screw and a cylinder that rotate in unison, having a common axial axis all the aforementioned elements, the augers having been conceived to advance the pasty mass of concrete, while the cylinders are responsible for configuring, as if it were lathes, the hollow parts of the continuous plate, which at the same time, it is subjected to the compaction that a vibration bridge located above it holds, as well as a mold made up of two side walls, responsible for forming the sides of the continuous plate, advancing the machine on the rails thanks to the combined forces that on the concrete mass make the screws and the vibrating mechanism, and find these forces the resistance offered by the plate as it emerges from the machine and gradually solidifies on the track between the rails.
