Abstract
A formwork panel assembly for concrete building construction has a pair of formwork panels with parallel walls, an elongate support member extending between the walls and a clamp securing the walls of the formwork panels to the support member. The support member has a substantially U--shaped cross-section with a pair of opposite sides and an opening between the opposite sides. The clamp has a pair of clamp jaws each having a first projecting portion, the support member and the parallel walls extending between the first projecting portions of the jaws, and a second projecting portion, the second portions extending into the opening between the opposite sides of the U-shaped cross-section. A wedge displaces the clamp jaws relative one another to caus e the first portions to exert a clamping pressure urging the pair of parallel walls against the opposite sides of the U-shaped cross-section and simultaneously urging the second portions apart from one another against the opposite sides of the U-shaped cross-section to counteract distortion of the opposite sides by the clamping pressure.
