Device for vibrating and compacting

Abstract

The invention concerns a vibrating machine for vibrating and compacting of compactable materials, in particular raw concrete filled into concrete molds for concrete mold parts, preferably low water content raw concrete, wherein the vibrating machine is comprised of a machine base (1), an oscillator (6) and a vibrating table (4) which can be caused to vibrate by oscillations of the oscillator (6), upon which a concrete mold (16) for the concrete molded parts can be placed, wherein means are provided for coupling the concrete mold (16) and the vibrating table (4) to each other for reduction of noise. The means for coupling comprises a vacuum coupling (4, 13, 16), which draws the vibrating table (4) and the concrete mold (16) form locking towards each other during the vibrating process. The vacuum coupling is preferably comprised of the vibrating table, the base (19) of the concrete mold (16), a hollow space (17) between the vibrating table and the base of the concrete mold (16), as well as a vacuum seal (15) surrounding the hollow space.
