Abstract
A device for molding internal cavities in elongated concrete bodies, characterized in that it consists of a hollow cylinder fixedly fixed at one end and with a cap threaded on the other; a solid body located inside said cylinder in contact with its inner walls and shorter than the cylinder, so that said solid body can run inside the cylinder, being provided with central holes the two caps of the cylinder and the solid inner body, remaining said holes in alignment and the solid body having at one end a frusto-conical extension and a transverse hole in which a pin is located which, when introduced, is wedged against the central rod passed through the longitudinal hole of the solid body , so that said body and said rod are firmly fixed to each other so that when a pulling or pushing force is exerted on the rod, in order to displace it, the solid body follows its displacement.
