<p>A concrete form panel (25) has a non-removable lifting claim (31) with one end attached to an anchor pin (28). The pin does not protrude from an upper peripheral rib (15) which extends outwardly from the form panel. The other end of the chain (36) is adapted to engage with a lifting hook of a crane. The length of the chain is such that the lifting angle is approximately 60°. Also disclosed is a clamping assembly to clamp form panels together. The clamping assembly comprises an elongate locking channel which is fitted over abutting elongate ribs (17, 18) on adjacent panels to lock the ribs together.</p> |
