摘要： An improved flatwork concrete finishing apparatus includes a side-by-side pair of parallel spaced elongate brush assemblies, each brush assembly having an elongate head with a pair of upper corners or stops, a downwardly directed throat with opposing inwardly directed grooves, and a plurality of replaceable elongate blocks, each having at least one row of color-coded bristles with a stiffness different than the bristles of at least one of the other blocks. Each of the blocks have outwardly directed ridges adapted to be slidably received by the grooves. A plurality of corresponding pairs of brackets attached to each of the pair of brush assemblies are interconnected by a plurality of spacers pivotally connected thereto. Interaction between the spacers and one of the stops of each of the brush assemblies establishes the angular orientation of the brush assemblies as the apparatus is displaced across the flatwork in one direction, and between the spacers and the other stops of the brush assemblies establishes the equal but opposite angular orientation of the brush assemblies as the apparatus is displaced across the flatwork in the opposite direction. The pair of brush assemblies are adapted to be disassembled and interchangeably attached to a screw-on type handle or a push-pin type handle for small jobs.
