摘要

Vertical reinforcing bars (V) in each corner of a void are located by profiles (2-5) fixed in the corners of the modules, the profiles being of an 'S' section providing a guide ramp and a segmental groove locating the bar. Tapered notches (8, 11) in the top edges of each module locate horizontal bars (H), having one vertical and one inclined wall positioning the bar accurately against the vertical bars. Tell tale openings (21) may also be provided in the top external edge, providing a check on the progress of the concrete pour, and being of rectangular elevation with a ramped invert falling towards the exterior.
