Abstract
A concrete screed assembly broadly includes a plurality of elongated drum sections. The drum sections are interchangeably interconnectable in an end-to-end relationship to cooperatively form a rotatable concrete screed drum that is selectively variable depending on the drum sections interconnected to form the drum. The drum sections each present a concrete-forming outer surface configured to engage concrete as the drum is rotated. The drum sections each include opposite connection ends.
Claims25
A concrete screed assembly comprising:
- a plurality of elongated drum sections interchangeably interconnectable in an end-to-end relationship to cooperatively form a rotatable concrete screed drum,
- said drum sections each presenting a concrete-forming outer surface configured to engage concrete as the drum is rotated,
- said drum sections each including opposite connection ends,
- said connection ends each including an alignment element;
- and
- an adapter interposed between a corresponding pair of the connection ends of adjacent drum sections,
- said adapter including alignment structure that engages the alignment elements of the corresponding pair of connection ends, with the alignment structure of the adapter and each engaged alignment element cooperatively defining an interengaging male/female coupling.

A concrete screed assembly comprising:
- a plurality of elongated drum sections interchangeably interconnectable in an end-to-end relationship to cooperatively form a rotatable concrete screed drum being selectively variable depending on the drum sections interconnected to form the drum,
- said drum sections each presenting a concrete-forming outer surface configured to engage concrete as the drum is rotated,
- said drum sections each including opposite connection ends that are similarly constructed, such that each connection end of one of the drum sections is operable to interconnect with either of the connection ends of any of the other the drum sections.
