Floor deck structure and composite floor deck

Abstract

A floor deck structure (1) including a profiled metallic sheet (2) including at least a first, a second and a third upper portion (7) separated by a first and a second longitudinal groove (3) comprising a base (5), a first lateral wall (13) linking the base (5) to one of the upper portions and a second lateral wall (14) linking the base (5) to an adjacent upper portion (7); a first and a second rebar truss (10) each extending longitudinally in and/or above, respectively, the first and second longitudinal groove (3) and a plurality of connectors (9a) fastening the first and the second rebar trusses (10) to the profiled metallic sheet (2).

1 - 14 . (canceled) 
     
     
         15 . 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.   
     
     
         16 . The floor deck structure as recited in  claim 15  wherein the connectors include a first and a second side respectively fastened to the first lateral wall and the second lateral wall. 
     
     
         17 . The floor deck structure as recited in  claim 15  wherein the shape of each of the connectors matches at least partially the shape of a corresponding one of the first and second longitudinal grooves. 
     
     
         18 . The floor deck structure as recited in  claim 15  wherein the profiled metallic sheet has a unique transverse shape. 
     
     
         19 . The floor deck structure as recited in  claim 15  wherein a height dimension between the base of the first and second grooves and the adjacent one of the first, second and thord upper portions is between thirty millimeters and eighty millimeters. 
     
     
         20 . The floor deck structure as recited in  claim 15  further comprising at least one longitudinal plate including a longitudinal side fastened to the base of the first or second longitudinal groove and extending perpendicularly to the base. 
     
     
         21 . The floor deck structure as recited in  claim 15  wherein each of the first and second rebar trusses includes a plurality of longitudinal metallic rebars. 
     
     
         22 . The floor deck structure as recited in  claim 15  wherein each of the first and second rebar trusses has a triangular transverse section. 
     
     
         23 . The floor deck structure as recited in  claim 15  wherein each of the connectors is designed for, and capable of, being clipped on a corresponding one of the first and second rebar trusses. 
     
     
         24 . The floor deck structure as recited in  claim 15  wherein each of the connectors is unmovingly fastened to the profiled metallic sheet. 
     
     
         25 . The floor deck structure as recited in  claim 15  wherein the first and second rebar trusses are unmovingly fastened to the plurality of connectors. 
     
     
         26 . A composite floor deck comprising:
 the floor deck structure as recited in  claim 15 ; and   a concrete structure embedding the first and second rebar trusses and anchored to the metallic sheet.   
     
     
         27 . 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.   
     
     
         28 . A process for assembling a composite floor deck, the process comprising the steps of:
 providing the floor deck structure as recited in  claim 15 , and   pouring concrete on the metallic sheet of the floor deck structure in order to encompass the first and second rebar trusses.
