ABSTRACT:
A vibratory concrete screed includes a generally triangular, open support frame to which front and rear screed blades are coupled. Air vibrators are coupled at intervals along the front and rear screed blades to impart vibratory motion to the blades. First and second end brackets are coupled to the screed top pipe and to the front and rear screed blades and include first and second side members which define a plane oriented perpendicular to the front and rear screed blades. A vertically and horizontally adjustable extension bracket is coupled to the first and second side members of the end bracket of the screed and is maintained in a plane perpendicular to the plane defined by the first and second side members of the end bracket.
