Abstract

Four identical 'L' shaped pieces (2, 3, 4, 5) are incorporated in an adjustable shuttering collar for reinforced concrete square section columns (1), connecting to form a ring without any fasteners traversing the shutters. A primary leg has a length exceeding that of the max required column side, the secondary leg (13) comprising two back to back U-sections with aligned web-holes (15) at longitudinal intervals. A perpendicularly movable box section tongue (12) is mounted at the free end of the primary leg, having two holes (17) at one end and contg. a captive wedge (21) at the other.
