摘要
The shuttering unit comprises a table(2) with demountable side forms(3, 4, 5) on a movable frame(1). Openings(8) in the transverse side forms(5) locate full length core-formers (10), and the frame may pivot to position the shutter on edge. One of the transverse forms can slide between the longitudinal forms, the former having plane internal faces with holes(18) locating reinforcing bars, and the latter incorporating longitudinal groove-forming ribs. The core-formers may be of a splayed rectangular section, may be threaded through the transverse forms, and may be a collapsible arrangement of two 'U' sections each comprising inter-articulating 'L' sections.
