Support apparatus and formwork used in casting concrete floors

摘要

The invention relates to a support apparatus for use in forming a concrete floor of a building or other structure and consists of a formwork for retaining wet concrete in position while it is setting and a tower for supporting the formwork. The formwork comprises at least one pan which is hingedly mounted for movement between an unfolded position in which it extends laterally outwards from the tower and a folded position in which it extends alongside the tower. Preferably there are nine square pans in total (A-I figure 4) arranged around a central square pan (A figure 4) mounted on the tower. The pans may be raised or lowered by gas damping springs 4 and supported in the raised position by struts 1. A later embodiment relates to a system of formwork comprising said support apparatus.
