Process for producing a recess in the base region of a wall construction, corresponding wall construction and system and construction element therefor

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.

Claims

9. The wall construction according to claim 8, characterized in that the compensating insulant introduced into the intermediate space between the panelings of the stud frame comprises an insulant suitable for ensuring the fireproofing and/or sound insulation.

10. The wall construction according to claim 8, characterized in that the intermediate space between the panelings of the stud frame is completely filled with the compensating insulant at least in its base region.

11. The wall construction according to claim 8, characterized in that strips of compensating insulant are placed into the base region.

12. The wall construction according to claim 8, characterized in that the compensating insulant is arranged in the intermediate space between the panelings of the stud frame without mechanical fastening.

13. The wall construction according to claim 8, wherein the wall construction has fire protection and/or sound insulation.

14. The wall construction according to claim 8, wherein the board-shaped construction elements contain gypsum and/or cement.

15. A system for producing a wall construction, comprising: profile elements for a stud frame and board-shaped construction elements, for attaching an at least single-layer paneling to both sides of the stud frame; wherein at least one recess is produced in the base region of the wall construction according to claim 8, further including at least one compensating insulant strip for compensating the weakening of the base region resulting from the recessed paneling.

16. A wall construction in the drywall technique, comprising: a stud frame comprising dual stud profiles, each of the stud profiles comprising a bottom rail fixed directly to a floor, with sides extending from the bottom rail, with board-shaped construction elements, attached on both sides of each stud profile; wherein for the production of a recess in the base region of the wall construction at least one side of each stud profile 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; and a compensating insulant introduced into the intermediate space above the bottom rail and between the panelings of each stud profile in a region approximating 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, wherein the compensating insulant comprises compactable rock wool and elastic dampening elements are located adjacent the bottom rail and/or below a lower edge of an inner panel of said double-layer paneling.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The attached drawings show exemplary embodiments, from which other inventive characteristics can also be gathered, but which basically should only be interpreted as examples and are not intended to restrict the object of the invention or its scope of protection in any way. In these drawings:

(2) FIG. 1 shows a basic vertical section through an inventive base region of an exemplary wall construction with a stud frame comprising single studs, and

(3) FIG. 2 shows a basic vertical section through an inventive base region of an exemplary wall construction with a stud frame comprising double studs.

DETAILED DESCRIPTION

(4) FIG. 1 shows a basic vertical section through an inventive base region of an exemplary wall construction with a stud frame that comprises single studs.

(5) The wall construction illustrated in FIG. 1 comprises in its shown base region a bottom rail 2 that is fixed on a floor 1, as well as stud profiles 3 that vertically rise from the bottom rail 2. Both sides of the stud profiles 3 are paneled with wall boards 4, 5 down to the floor 1. In the base region, however, the outer wall boards 5 are recessed or shortened on both sides of the stud profiles 3 in order to thereby respectively create a recess 6 in the base region. Not-shown baseboards can be fitted into these recesses 6 in such a way that they end flush with the outer surface of the outer wall boards 5, i.e. such that they do not or only slightly protrude into the room bordered or separated by the wall construction. This may have merely aesthetic reasons with respect to the interior design.

(6) However, the remaining base region of the wall construction is narrowed and weakened in its illustrated cross section due to these recesses 6. This preferably counteracts any potential fire protection and/or sound insulation measures to be ensured with the wall construction.

(7) According to the invention, this weakened fire protection and/or sound insulation is compensated in that a suitable, special compensating insulant 7, particularly a highly heat-insulating, non-combustible and/or sound-absorbing insulant, preferably rock wool, is introduced into the weakened base region, namely into the region of the compartments formed by the stud profiles 3 between the wall boards 4 of the inner paneling. This is preferably already carried out during or shortly after the construction of the stud frame, but before the panelings are attached or closed. With respect to the illustration in FIG. 1, it is noted that the fastening screws 8 shown merely serve for fastening the panelings on the stud frame whereas the compensating insulant 7 is preferably not mechanically fastened on the stud frame. The height of the special compensating insulant 7 preferably exceeds the height of the recesses 6 in the vertical direction.

(8) The wall boards 4, 5 may preferably be gypsum boards, gypsum plaster boards or gypsum fiber boards.

(9) A conventional insulant 9, for example glass wool, can be used above the special compensating insulant 7, i.e. in the regions, in which the double paneling is still intact.

(10) FIG. 2 shows a basic vertical section through an inventive base region of an exemplary wall construction with a stud frame that comprises double studs. Identical construction elements are identified by the same reference symbols as in FIG. 1.

(11) In contrast to the exemplary embodiment illustrated in FIG. 1, the wall construction in FIG. 2 has a double stud construction, i.e. two stud profiles 3 are arranged adjacent to one another. The panelings are arranged to both sides of this double stud construction and otherwise realized as in FIG. 1.

(12) In addition, the wall construction in FIG. 2 features elastic damping elements 10 for acoustically damping and decoupling the wall construction.
