(57) A steel soldier for supporting concrete formwork comprises a pair of elongated steel
elements connected back to back and parallel with one another by tie plates (3) at
their ends and, if necessary, by diaphragms intermediate their ends. Each channel
has a web (1) which, in order to increase its strength, is formed at longitudinally
spaced intervals with flanged openings (1a). These openings characteristically according
to the invention have peripheral flanges (1c) which are of channel-shaped radial profile,
thereby increasing the shear carrying capacity and reducing the risk of cracking of
the soldier under load.
