<p>The main vertical formwork members (1) are concave in cross section, either trapezoidal or curved, and may be lined or filled with insulation (3) on the inner face (2). The panel elements (1) have interlock grooves (12,14) on the long edges for receiving T-shaped projections (23) on the sides of a connecting spacer rib (8) in a sliding fit. - The ribs, acting both as spacers and ties, are generously apertured for the insertion of reinforcement and to allow the free flow of concrete. Special elements may include curves (44), corners (45), stop-ends (42), and filler pieces (13) if a flat face surface is required.</p> |
