A cross edge rolling process for increasing a thickness of a strip in longitudinal edge strips on both longitudinal sides of the strip. According to the invention, this is achieved in that firstly a step extending in the longitudinal direction of the strip is produced by means of a roll profiling process, wherein the strip is supported during the cross edge rolling process on said step against a compression force acting transversely to the strip, so that the strip is not compressed outside the longitudinal edge strip. After the edging process for increasing the thickness of the longitudinal edge strips, the strip is bent by means of a roll profiling process to form a C-profile rail.

A fastener includes an anchor bolt and a nut. The nut has a nut hole and an internal thread. The anchor bolt has an anchor portion and a threaded rod that has an external thread and that is connected to the anchor portion. The nut is arranged on the threaded rod and the internal thread of the nut threadedly engages the external thread of the threaded rod. The nut has a rearward nut section, a forward nut section, and an outside shoulder for load transfer into the nut which is located between the forward nut section and the rearward nut section and which faces the anchor portion of the anchor bolt. The internal thread of the nut extends at least in the forward nut section and threadedly engages the external thread of the threaded rod at least in the forward nut section.

An anchor channel of C-shaped cross-section for embedding in concrete, wherein a lip which adjoins the slot-like opening has been reinforced. In order to achieve high holding forces against withdrawal of a hammerhead element, a setting angle assumes a maximum value in a region that is located closer to the side wall than to the opening.

Anchor channel and combination of anchor channel and hammerhead element

A combination of an anchor rail with a hammer head element for setting in concrete. In order to achieve the best possible load-carrying capacity in the longitudinal direction L of the anchor rail, the anchor rail has toothing, specifically in a region close to a slot-like opening for the insertion of the hammer head element. The hammer head element, in a force-free state, rests only on the toothing and comes to rest over an entire head upper side only in the case of increased tensile forces, as a result of which the force transmission moves outwards to side walls of the anchor rail. This facilitates the load-carrying capacity of the anchor rail with respect to tensile forces.

A roller forming device and method for forming a material provided with geometric elements, in particular holes, is disclosed. The device has at least one forming roller and at least one counter roller, wherein a roll gap is configured between the forming roller and the counter roller for carrying through the material. The forming roller has a molding structure on its cylindrical surface, which molds the material when the material runs through the roll gap. The forming roller has carrier elements for an engagement with the geometric elements of the material running through the roll gap.

A method for producing a profile from a sheet-metal strip is disclosed. The sheet-metal strip is bent at least twice during a first stage, where, as viewed in the cross-section of the sheet-metal strip, a center section as well as two flank sections are formed, which project angularly from two opposing end regions of the center section. During a second stage following the first stage, the center section is compressed by two complementary roller arrangements which engage on the two opposing end regions of the center section, and the sheet-metal strip is thereby locally thickened.

A process of producing profiles whose cross-section is variable in the longitudinal direction, characterized by the process stages of cutting a blankwith a substantially constant width along a longitudinal direction, deforming the blankby deep-drawing to form an open profile whose cross-section is variable along the longitudinal direction, and cutting the flanges projecting from the open profile.

A conduit hanger with at least one bracket element to receive a pipe, with a load-distribution plate that is placed into the bracket element, and with a fastening device for fastening the load-distribution plate to the bracket element. The fastening device has at least one catching element to grip the bracket element as well as a counter-bearing element, which are arranged offset on the load-distribution plate in the lengthwise direction of the plate, and between which a holding space is formed for the bracket element, and that the front of the bracket element has at least one recess that corresponds to the catching element so that the bracket element can be placed into the holding space.

A fastening arrangement, including a quick-action nut that has two nut parts. The nut parts each have a groove to receive a threaded rod, and including a locking element with at least one passage opening for securing the quick-action nut to the threaded rod. In the passage opening, the locking element has a locking surface for pressing the nut parts against the threaded rod as well as a centering surface for centering the threaded rod in the passage opening. In the passage opening, the locking element has a transition surface that adjoins the locking surface and the centering surface, and that runs between the locking surface and the centering surface.
