US 8,739,491 B2 · Thin-walled, cold formed lightweight structural profile element and method for producing such a profile element

Abstract

The invention relates to a thin-walled, cold-formed profile element, in particular a structural profile, for example a drywall construction, facade, plaster, screed, tile or cable carrier profile or a shelf or drain rail. The profile element has an elongated profile body, in particular metallic or consisting of plastic, in which a multiplicity of openings is formed. The profile body comprises at least two separately constructed longitudinal sections, each longitudinal section comprising a serpentine longitudinal edge. The longitudinal sections each comprise an elongated section and a plurality of connecting sections projecting laterally beyond the elongated section, which are bordered by the serpentine longitudinal edge. The connecting sections of the one longitudinal section face the connecting sections of the other longitudinal section and are in each case welded to the latter edge to edge or joined to one another along curved abutting edges. At least in some sections, the openings are bordered by sections of the serpentine longitudinal edges. Formed in the longitudinal sections are reinforcing beads running in the longitudinal direction of the longitudinal sections and also reinforcing beads running transversely thereto, the reinforcing beads running transversely being connected to the reinforcing beads running in the longitudinal direction, and the reinforcing beads running transversely extending into the connecting sections. The invention further relates to a method for producing such a profile element.

A thin-walled cold formed lightweight sectional element having an elongated section body (2) in which a plurality of openings (5) are formed,

wherein the section body (2) includes at least two separately formed longitudinal portions (10, 11);
wherein each longitudinal portion (10, 11) includes a meandering longitudinal edge (12, 13);
wherein the longitudinal portions each include an elongated portion (16, 17) as well as a plurality of connection portions (14, 15, 23, 24, 37, 38, 45, 46, 47, 48) which project laterally beyond the elongated portion (16, 17) and which are bordered by the meandering longitudinal edge (12, 13);
wherein the connection portions (14, 23, 37, 45, 47) of the one longitudinal portion (10) face the connection portions (15, 24, 38, 46, 48) of the other longitudinal portion (11) and are welded to them end-to-end in each case or are connected to one another along bent-over abutment edges (56);

A method for manufacturing a thin-walled cold formed lightweight sectional element having an elongated section body (2) in which a plurality of openings (5) are formed, the method comprising the steps of:

providing two separate longitudinal portions (10, 11) each having a meandering longitudinal edge (12, 13) to produce the section body (2), with the longitudinal portions (10, 11) in each case including an elongated portion (16, 17) as well as a plurality of connection portions (14, 15, 23, 24, 37, 38, 45, 46, 47, 48) which project laterally beyond the elongated portion (16, 17) and which are bordered by the meandering longitudinal edge (12, 13);
moving apart the longitudinal portions (10, 11) transverse to their longitudinal extent;
and
welding the connection portions (14, 23, 37, 45, 47) of the one longitudinal portion (10) to the connection portions (15, 24, 38, 46, 48) of the other longitudinal portion (11) end-to-end so that the openings (5) are formed between portions of the meandering longitudinal edges (12, 13);
forming stiffening beads (31) extending in the longitudinal direction of the longitudinal portions (10, 11) as well as forming stiffening beads (30) extending transverse thereto in the longitudinal portions (10, 11), with the transverse extending stiffening beads (30) being in communication with the stiffening beads (31) extending in the longitudinal direction and the transverse extending stiffening beads (30) extending into the connection portions (14, 15, 23, 24, 37, 38, 45, 46, 47, 48) and beyond the weld seams between the connection portions (14, 15, 23, 24, 37, 38, 45, 46, 47, 48).
