Abstract The invention pertains to an assembling device for setting up metal structures, characterized on the one hand, by the fact that the uprights are built as box-type elements having a front plane portion adjacent to two deep mouldings, which themselves are next to the side walls, to which aforesaid mouldings are connected by a semitubular edge, aforesaid deep mouldings being provided with spaced elongated openings, and on the other hand, by the fact that the hooking elements, which are integral with the cross-members, are provided along their height with alternate parallel and perpendicular protrusions with respect to aforesaid front face of the upright, aforesaid perpendicular protrusions fitting into aforesaid openings provided in the bottom of the deep mouldings in the upright.
In a metal structure having a plurality of upright post members and cross members extending between said post members, the improvement comprising: said post members each having spaced parallel side walls curved inwardly at their forward edges to define semi-tubular front portions, then reversely bent to define channels adjacent said semi-tubular portions and a central planar front face between said channels; a pair of vertical rows of first openings in said front face; a vertical row of second openings in the bottom of each of said channels; said cross members each having an end plate perpendicular thereto abutting a side wall of a post and having alternating portions extending across an adjacent channel into abutment with said front face with intermediate portions bent to closely embrace the adjacent semi-tubular portion and extend into said adjacent channel; each of said intermediate portions having a downwardly hooked inner edge engaged in one of said second openings; and said portions extending across said adjacent channel having upper edges generally coincident with lower edges of first openings of one of said rows.
