Prefabricated Structural Concrete Beam and Methods for Use

摘要

A structural beam, and methods for use, comprising a prefabricated structural concrete portion and a poured-in-place structural concrete portion, wherein said poured-in-place portion comprises at least ten percent of the total weight of said structural beam. Reinforcing extends from the prefabricated portion to the poured-in-place portion. In a preferred embodiment, the structural beam is an “inverted-T” beam, and the prefabricated structural concrete portion comprises the lower corbel portion of the beam, and the poured-in-place portion comprises an upper stem portion of the beam.
