Abstract (en)

The shuttering is made from a series of adjacent rock wool panels (l1, l2) with anchoring elements (E1, E'1, E2, E'2) for reinforcing mesh (T) on one side and metal reinforcing sheets (1) on the other. The metal sheets, made from galvanised steel, have raised sides (3, 4) and turned-over horizontal edges (7) that engage with slots in the rock wool panels. The base of each metal sheet has lengthwise stiffening ribs, while its turned-over edges have V-section locking ribs (30).
