Abstract:
A device for receiving formwork elements for the manufacture of concrete structural parts, the device comprising:(A) a static carrying structure;(B) a formwork shell which 1) has a flat upper surface that forms means for directly supporting the concrete, and 2) defines means for being set in vibration;(C) an intermediate layer via which the formwork shell is supported on the static structure, the intermediate layer being formed from a sound-insulating and vibration-insulating viscoelastic material disposed between the static structure and the formwork shell; and(D) exciter means, bypassing the intermediate layer and engaging the formwork shell, for setting the formwork shell in vibration so as to compact still-plastic concrete supported directly thereon, and wherein the intermediate layer insulates the static structure from sound and vibrations in the formwork shell.
