Abstract

A composite beam especially for pile driving comprises an H-beam core whose flanges are bridged by steel sheets having inwardly bent edges engaging over outwardly projecting spurs on the flange edges. The web of the H-beam thus defines with the sheets two compartments which are internally lined with colloidal concrete, the outer steel surfaces being likewise coated with colloidal concrete.
