ABSTRACT:
A vibrating apparatus for forming a concrete block by a vibration compaction method. The apparatus has a mold box for contouring a concrete block to be produced, a receiving plate which is detachably and resiliently attached to the bottom of the mold box, a device for vibrating the mold box, and an air spring device which permits a close and resilient contact between the mold box and the receiving plate. This close contact permits the receiving plate to effectively follow the vibration of the mold box. The vibration of the mold box is effectively transmitted to the concrete block material.
