Formwork element profiled sheet steel for the production of floors with interacting metallic principal

摘要

The formwork component (1) for making the metal pan (4) has a section composed off a succession of omega shapes (7). These shapes have a top (8) on either side of which extend two inclined web plates (9) and two sole plates (10). On the web plates are beads (12) located on the diagonal (13) of a rectangle representing a design. The beads define a number of designs forming inclined notching. An Independent claim is also included for the pan joist concrete floor.
