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.
Claims42
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,
- each of said connection ends including a plurality of fastener pockets recessed radially inward relative to the outer surface of the drum;
- and
- a plurality of fasteners interconnecting the connection ends of adjacent drum sections,
- each of said fasteners extending into corresponding ones of the pockets of the interconnected connection ends.
A concrete screed assembly comprising:
- a plurality of elongated drum sections 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, such that an adjacent pair of drum sections forming at least part of the drum present interconnected connection ends,
- said interconnected connection ends each including a plurality of fastener pockets recessed radially inward relative to the outer surface of the respective drum section;
- and
- a plurality of fasteners interconnecting the connection ends of the adjacent drum sections,
- each of said fasteners extending into corresponding ones of the pockets of the interconnected connection ends.
An interchangeable drum section interconnectable in an end-to-end relationship with other interchangeable drum sections to cooperatively form a rotatable concrete screed drum selectively variable depending on the drum sections interconnected to form the drum, said interchangeable drum section comprising:
- an elongated drum body presenting a concrete-forming outer surface configured to engage concrete as the drum is rotated,
- said drum body including opposite connection ends that are similarly constructed, such that each connection end is operable to interconnect with either of the connection ends of the other drum sections,
- said drum body presenting a central rotational axis,
- said connection ends including respective alignment elements, each being configured to at least in part cooperate with an alignment element of one of the other drum sections to align the rotational axes of interconnected drum sections, such that the drum has a common axis of rotation,
- each of said connection ends including a plurality of fastener pockets recessed radially inward relative to the outer surface of the drum body.
A drum section interconnectable in an end-to-end relationship with other drum sections to cooperatively form a rotatable concrete screed drum selectively variable depending on the drum sections interconnected to form the drum, said drum section comprising:
- an elongated drum body presenting a concrete-forming outer surface configured to engage concrete as the drum is rotated,
- said drum body including opposite connection ends,
- each of said connection ends including a plurality of fastener pockets recessed radially inward relative to the outer surface, such that corresponding pockets of interconnected adjacent drum sections of the drum are configured to receive a fastener interconnecting the adjacent drum sections.
