Floor deck structure and composite floor deck

A floor deck structure comprising:

• a profiled metallic sheet including at least a first, a second and a third upper portion separated by a first and a second longitudinal groove, each including a base, a first lateral wall linking the base to one of the first, second and third upper portions and a second lateral wall linking the base to an adjacent one of the first, second and third upper portions;
• a first and a second rebar truss each extending longitudinally in or above, respectively, the first and second longitudinal groove;
• and
• a plurality of connectors fastening the first and the second rebar trusses to the profiled metallic sheet so that relative movement of the first and the second rebar trusses with respect to the profiled metallic sheet is prevented.

A process for assembling a floor deck structure, the process comprising the steps of:

• providing a profiled metallic sheet including at least a first, a second and a third upper portion separated by a first and a second longitudinal groove, each including a base, a first lateral wall linking the base to one of the first, second and third upper portions and a second lateral wall linking the base to an adjacent one of the first, second and third upper portions;
• providing at least a first and a second rebar truss;
• respectively positioning the rebar trusses in or above the first and second longitudinal grooves;
• and
• fastening the first and the second rebar trusses to the metallic sheet using connectors so that relative movement of the first and the second rebar trusses with respect to the profiled metallic sheet is prevented.
