Abstract
A structural concrete beam, and method therefor, 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 concrete beam. Reinforcing extends from the prefabricated portion to the poured-in-place portion. In a preferred embodiment, the structural concrete 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 structural concrete portion comprises the remaining upper stem portion of the beam.
Claims20
A structural concrete beam, comprising:
- a prefabricated structural concrete portion;
- 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 concrete beam;
- and
- reinforcing extending from said prefabricated structural concrete portion into said poured-in-place structural concrete portion.
A method for constructing a structural concrete beam, the method comprising:
- prefabricating a portion of said structural concrete beam;
- erecting said prefabricated portion of said structural concrete beam;
- erecting formwork for facilitating the placement of a remaining poured-in-place portion of said structural concrete beam;
- and
- placement of said remaining portion of said structural concrete beam in-place, whereby said poured-in-place portion comprises at least ten percent of the total weight of said structural concrete beam.
A method of constructing an “inverted-T” structural concrete beam, the method comprising:
- prefabricating a lower corbel portion of said structural concrete beam;
- erecting said prefabricated portion of said structural concrete beam;
- erecting formwork for facilitating the placement of a remaining poured-in-place stem portion of said structural concrete beam;
- and
- placement of said remaining portion of said structural concrete beam in-place, whereby said poured-in-place portion comprises at least ten percent of the total weight of said structural concrete beam.
