Table-form/flying-form. A table form/flying form is a large pre-assembled formwork and falsework unit, often forming a complete bay of suspended floor slab. It offers mobility and quick installation for construction projects with regular plan layouts or long repetitive structures, so is highly suitable for flat slab, and beam and slab layouts.
Methods of placing should be such as to avoid segregation. Care should be taken to avoid displacement of reinforcement or movement of formwork. Formwork should be continuously watched during and after the concreting. In case of leakages, bulging or sagging immediate action should be taken before initial setting of the concrete.
