ABSTRACT:
Rebars to be embedded in a monolithic concrete structure are spliced together; also deformed rebars are spliced together across an expansion joint or construction joint between two or more monolithic concrete pours in that one rebar is provided with a threaded receiver barrel, possibly having a flange, and into which is introduced the, preferably, expanded and threaded end of the other rebar; no third splicing element is involved. Short rebars with a receiver at one end can also serve for defining anchor points in the outer surface of a concrete structure.
