Definitions

• the present invention relates to a sheet metal profile for drywall construction.
• Sheet metal profiles are used in dry construction in various designs.
• a known embodiment of such a profile is referred to as C-profile and has two leg portions and a bottom portion connecting the leg portions, wherein on the leg portions each one extending in the longitudinal direction of the profile bent supporting edge is provided.
• Object of the present invention is to provide a particularly stable for a given material thickness profile. This object is achieved by a profile of sheet metal for drywall with two leg sections and a bottom portion connecting the leg sections, wherein at least one of the leg sections is provided in the longitudinal direction of the profile extending bent support edge, wherein on the bent support edge a reinforcing strip is provided and wherein the reinforcing strip extends over the entire width of the folded support edge solved.
• a further improvement in stability is achieved in that the reinforcing strip and / or the bent-over support edge has plastic material deformations for fastening the reinforcing strip to the bent-over support edge.
• a plurality of local plastic material deformations may preferably be provided.
• the plastic material deformations have an elongated shape and extend in particular in the longitudinal direction of the reinforcing strip.
• the plastic material deformations can be produced by forming joining of supporting edge and reinforcing strip, in particular by clinching.
• the stability of the profile can be further improved.
• the production of the profile is particularly simple if the reinforcing strip is a bent-back part of the leg section.
• the reinforcing strip may be a separate element, in particular a sheet metal strip.
• a forming step of the sheet can be omitted since the reinforcing strip is not bent back.
• the reinforcing strip may instead be separately fed during manufacture and e.g. be connected by the plastic material deformations with the supporting edge.
• the reinforcing strip extends along the supporting edge, in particular over its entire length, and / or is arranged on the side of the supporting edge facing the bottom section.
• the supporting edge in the transverse direction of the supporting edge has a curvature. This can be designed such that the supporting edge facing away from the bottom portion Side convex and / or concave on the side facing the bottom portion.
• the stability is also improved in that the reinforcing strip has a first region for bearing against the supporting edge and a second region for abutment with the leg section.
• the first and the second area can be connected to each other via a bending line. Good support is achieved when the first region extends parallel to the supporting edge and the second region extends parallel to the leg section.
