Abstract: A drywall anchor and a method for installing the drywall anchor. The drywall anchor includes a drilling element at the front end of a base body for the introduction into a gypsum plaster board in a self-drilling manner and a non-circular region having a cross-section including at least three corners at the outer contour thereof. In particular, the non-circular region forms a prism.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A multi-chamber cartridge having an outer tube and an inner tube arranged coaxially in the outer tube for a separate storage of two components—e.g., a hardener and binder of a two-component synthetic resin. The multi-chamber cartridge has a pushing-out element with four cutting edges, which cut the inner tube of the multi-chamber cartridge into four strips when the multi-chamber cartridge is pushed out, that roll up, fold, and/or bunch up in four receiving spaces in the pushing-out element. The pushing-out element has a head pin, the head of which seals in the inner tube. In order to injection-mold the pushing-out element from plastic, a collar of the pushing-out element surrounding the head pin has two collar openings opposite each other, through which two sliders of an injection mold for demolding the pushing-out element are pulled out after injection molding, that form a shank of the head pin.

Abstract: Multi-component synthetic mortar fixing system, especially for fixing anchoring elements in building substrates, which comprises in one component reactive synthetic resins (i) based on urethane (meth)acrylate, (ii) based on epoxy resin or (iii) based on free-radical-hardening (or -hardenable) unsaturated reactive resins, in a further component hardener, and at least one filler selected from oxides of silicon and aluminium, or mixed oxides in the presence of further cations, the d50 average particle size of which is 50 ?m or less, and also especially a silane having at least one hydrolysable group, and also its use, methods including its use in fixing anchoring elements in building substrates and related subject-matter.

Abstract: An expansible fixing plug, having a sleeve-like portion, an expander body, and an expansion part which has expansion elements which, in a non-expanded state, are integrally joined to the sleeve-like portion and to the expander body. In addition, the expansion part has connecting elements which integrally join the sleeve-like portion and the expander body in the non-expanded state and also in the expanded state. The connecting elements are interlockingly connected to the expander body.

Abstract: An anchor for an anchoring with, for example, a synthetic resin mortar in an anchoring hole in an anchoring substrate made, for example, of stone, concrete or masonry. In order that a displacement of the anchor in the direction of a mouth of the hole and, as a result, potential failure of the anchoring can be ascertained at an early stage, a cap as position sensor holder having an electrical counter-contact, which cap is mounted on the anchor. If the anchor becomes displaced, the counter-contact moves out of contact with the anchor, with the result that the displacement can be ascertained.

Abstract: A toggle fixing with two obliquely arranged compression elements which enter into engagement with a screw thread of a screw passed through a screw hole and provide triangular support for the screw. A tension element absorbs compressive forces of the compression elements.

Abstract: A toggle fixing having a crosspiece and a strip which is pivotally connected to the crosspiece via a flexible portion. The crosspiece is formed with a detent with which the crosspiece, on insertion through a through-hole in a plasterboard panel, is supported against a toothing of the strip.

Abstract: A toggle fixing for fixing to a panel which is accessible only from one side. The toggle fixing has a crosspiece and a strip which is flexible and, as a result, pivotally connected to the crosspiece and on which a sleeve is displaceable in the direction of the crosspiece. The sleeve is provided with a screw hole, so that a screw cannot be pushed through but rather needs to be screwed through the sleeve in order that it can be screwed into the crosspiece. The sleeve relieves the crosspiece of an axial force of the screw.
