Abstract:
An ergonomic non-motorized vibratory concrete screed is provided that is designed to be used in the fashion of a standing one-man wet screed having a double barred, floating strike plate oriented in a planar fashion with which to strike and consolidate a concrete slab surface. The vibratory concrete leveling device according to the invention includes a bracket assembly having an upper surface and a lower surface. The lower surface of the bracket assembly includes a plurality of spaced apart slots, each spaced apart slot extending across a width of the bracket assembly. A corresponding plurality of screed bars are removably positioned in the plurality of spaced apart slots. Each of the plurality of screed bars are loosely fitted into each corresponding slot to promote vibratory action during use. An elongated handle is provided having a first end attached to the bracket assembly and a second end for grasping by a user.
