Further details and examples are illustrated in the accompanying drawings and descriptions.
The formwork assembly includes a plurality of longitudinally-extending and laterally spaced-apart steel reinforcing bars.
The formwork assembly includes a hoop reinforcement shaped to extend about the reinforcing bars. The hoop reinforcement is configured to provide shear strength to concrete poured into the formwork so positioned.
The formwork assembly includes a plurality of receptacles circumferentially spaced-apart about, coupled to and radially inwardly-extending from the hoop reinforcement so as to promote a desired positioning or spacing of the reinforcing bars.
The formwork assembly includes a plurality of spacers circumferentially spaced-apart about, coupled to and radially outwardly-extending from the hoop reinforcement.
The formwork assembly includes a formwork shaped to extend about and be positioned in place via the plurality of spacers. There is further provided a concrete stirrup apparatus comprising said hoop reinforcement, receptacles and spacers.
