14. A construction element for a wall construction, preferably a drywall construction with fire protection and/or sound insulation, comprising: a strip of a highly heat-insulating, non-combustible and/or sound-absorbing insulant, preferably of rock wool, which is intended for being introduced into the base region of a stud frame.

Description

[0019] 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:

[0020] 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

[0021] FIG. 2 shows a basic vertical section through an inventive base region of an exemplary wall construction with a stud frame comprising double studs.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] The wall boards 4, 5 may preferably be gypsum boards, gypsum plaster boards or gypsum fiber boards.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] In addition, the wall construction in FIG. 2 features elastic damping elements 10 for acoustically damping and decoupling the wall construction.
