Abstract: A method for the production of a fastening element for dry construction elements involving feeding a flat sheet metal material through a nip formed between a top roller having first teeth and a bottom roller having second teeth, in order to create depressions and elevations as well as slanted sliding surfaces.

Abstract: Fastening element for dry construction elements, and method for the production of such a fastening element.

Abstract: A C-shaped sheet metal profile for partitions that are planked on both sides is provided. The C-shaped profile comprises two leg sections and a bottom section that interconnects the leg sections. The leg sections form lateral faces of the C-shaped profile. At least one of the leg sections is provided with beads which protrude outward and form a support area for the planking. At least some sections of the beads are embodied such that the support area corresponds to more than 5 percent and less than 25 percent of the lateral face when the depth of penetration of the beads into a planking amounts to 0.3 mm.

Abstract: The invention relates to a sheet metal section for dry construction, including two limb portions and a base portion that connects said limb portions. According to the invention, at least one of the limb portions is equipped with a bent supporting edge that extends in the longitudinal direction of the section, the bent supporting edge being provided with a reinforcement strip. The section is characterised in that the reinforcement strip extends over the entire width of the bent supporting edge.

Abstract: The invention relates to a sheet metal section for dry construction, including two limb portions and a base portion that connects the limb portions, in addition to at least one reinforcement strip that is situated on one of the limb portions. The sheet metal section is characterized in that it is equipped with a device for fixing the reinforcement strip to the limb portion.

Abstract: A C-shaped sheet metal profile for partitions that are planked on both sides is provided. The C-shaped profile is made up of two leg sections and a bottom section that interconnects the leg sections. At least one of the leg sections encloses an opening angle exceeding 90° along with the bottom section in the unstressed state of the C-shaped profile.

Abstract: A self-cutting fast construction screw for the fastening of fiber plates to a metal substructure carries on the screw shaft at least one turn of a thread. The screw core passes into a conical drill point. On the conical drill point two cutting edges are arranged in a symmetrical layout, said cutting edges cutting to a diameter located between the diameter of the screw core and the diameter of the outer thread tip. Upon impact on the metal substructure, the two cutting edges break off.
