Dry construction system for making partition walls, suspended ceilings or the like, carrier profile therefor, and use of this dry construction system

摘要

The present invention relates to a dry construction system for making partition walls (1), suspended ceilings or the like, with improved sound insulation properties. In particular, the invention provides a system including: a support structure (2) in the form of a metal load-bearing structure, a cladding (3) arranged on at least one side thereof, and an insulation layer (4), which is arranged in the region of the support structure (2), wherein the support structure (2) comprises a plurality of carrier profiles (22), to which at least one cladding (3) is secured, wherein the carrier profiles (22) are formed from a sheet material and comprise in the cross-section a base section (22a) as well as two limb sections (22b, 22b’) arranged perpendicular thereto, and wherein the limb sections (22b, 22b’) of the carrier profiles (22) comprise an embossing with regularly distributed elevations and depressions, wherein the base section (22a) of the carrier profile (22) comprises an embossing with elevations and depressions regularly distributed into an orthogonal array, such that regions of the carrier profile (22) comprise elevations with four neighbouring depressions and wherein the centre-to-centre distance between two adjacent elevations of the embossing on one side of the sheet material is between three and six times the rated sheet thickness, and wherein the base section (22a) is connected to the adjacent limb section (22b, 22b’) in each case by means of a curved section (22c) with an outer radius (R1) which amounts to at least three times the rated sheet thickness. This combination of features results in relatively little distortion of the sound reducing elevations over the curved sections of the carrier profile, as the distance between two adjacent elevations is relatively small compared to the radius of the curved section. This has the technical effect of improving the sound insulation properties of the curved section of the carrier profile and the carrier profile as a whole.
