摘要
Formwork comprising two facing casting panels (3) interconnected by hinged linking members for spacing the panels (3) apart to define a gap for receiving a filler material such as concrete, or holding them in a collapsed position for storage and transport. The hinged linking members consist of substantially zigzag-folded elongate members (7A), and each folded elongate member comprises opposite staggered portions (6) interconnected by oppositely angled tie-rods (4A) on either side of each of said opposite portions (6). The alternate opposite portions (6) of all the elongate linking members are mutually parallel and preferably connected to the panels (3) via fastening means (5, 12) that enable only one degree of rotational freedom. Said hinged linking members generate compressive forces in the cast concrete that are perpendicular and parallel to the outer wall surfaces, whereby a binding effect reinforcing the wall strength is achieved.
