摘要

A device assigned to a manufacturing apparatus with sliding formwork or displaceable densifying apparatus equipped with three stages of vibration, to compress the ribs of hollow plates of reinforced concrete with a vibrator that governs several vibratory plates, being provided for each nerve to form a plate vibrator or two vibrating plates arranged at a certain distance from one another, characterized by the arrangement of a ram that fixes the height of the ribs and that in a roller plate has for each rib to form a skate at least in front of the vibrating plates which compress the nerves by contact vibration, and because the tamper drive is so coupled with the drive of a material feeder, that the ram is fed with concrete whenever its runners are in their highest position.
