Abstract: A connecting element is provided for connecting an essentially vertically arranged or arrangeable upright for a non-bearing wall structure with an essentially horizontal bar, in particular a steel profile with a U-shaped cross section, preferably a ceiling profile, to allow a sliding compensation movement in essentially the vertical direction, and with at least one fastening section for fastening to the bar or the preferable ceiling profile of a load-bearing or non-loading-bearing ceiling structure and with a least one sliding guide for the upright.

Abstract: Edge profile 10 for forming a part of a suspended ceiling substructure comprising a plurality of support profiles arranged suspended from a raw ceiling of a building structure and a plurality of base profiles, each of which being attached to at least one of the plurality of support profiles, the edge profile 10 having a U-shaped cross-section with a base portion 11 capable of being fixed to a wall structure, a first leg portion 12 and a second leg portion 13, the first leg portion 12 having an outer section 122 and an inner section 121, wherein the outer section 122 is arranged offset towards the second leg portion 13 relative to the inner section 121.

Abstract: A process for producing a recess (“negative base”) in the base region of a wall construction in the drywall technique, preferably a wall construction with fire protection and/or sound insulation, wherein for the wall construction on a stud frame, using board-shaped construction elements, preferably construction elements containing gypsum and/or cement, a paneling is attached on both sides of the stud frame, and wherein at least one side of the stud frame is provided with a double-layer paneling, the outer paneling layer of which is recessed in order to produce the recess in the base region, a compensating insulant is introduced into the intermediate space between the panelings of the stud frame at least over the vertical height of the recess in the base region in order to compensate the weakening of the base region resulting from the recessed paneling.
