摘要

When the feet of rectangular prefabricated concrete columns are to be cast into vertical holes in a concrete foundation, ribs of truncated cone shape are moulded to the hole walls and mirror image male ribs on the foot. The internal ribs (15) are made on shuttering (12) of plastic material with a flexural modulus of 25000 kg/sq.cm. such as polyamide (NYLON RT), neoprene or chloroprene. The shuttering for the column foot is a mirror image. ADVANTAGE - This permits this shuttering to be recovered and to be used many times.
